Description

Roof Working Device with Truss Frame

The present invention relates to a design in which a truss structure is introduced into a frame for a lightweight design of a structure in a roof work device structure that works by hanging on a crane or the like.

The roof work device is a device necessary for installing, dismantling and repairing the roof material from the roof. More specifically, it provides a base for the operator to work safely, and at the same time, a working platform for loading roof materials such as slats is optimal. Relates to a roof work device to provide.

Roofing work is a dangerous work that is concerned with safety accidents and requires the development of safe and efficient work equipment.

In particular, slate, which has been used as a roofing material since the 1960s, contains a large amount of asbestos, a first-class carcinogen, and must be dismantled and sequestered as a dangerous substance that threatens the public's health. It must be handled legally.

Therefore, the development of a safe and efficient work device required for dismantling the slate is more socially required, but the development of an efficient device that can be applied to a small aerial work truck with a small allowable load has not yet been achieved.

Hereinafter, a configuration and a preferred embodiment including a truss frame according to the present invention will be described with reference to the drawings.

1 is a first perspective view of a roof working apparatus having a truss frame according to the present invention.

Roof working apparatus having a truss frame of the present invention is connected to the vertical connecting beam 10 to the adapter of the boom end, such as a crane, the main frame 100 is rotatably connected to the lower vertical connecting beam, the main frame angle It is possible to control the inclination angle of the main frame by the control means 40.

The turntable 20 to enable the roof work device to rotate about the vertical axis and the composite shock absorber 30 to mitigate the impact may be assembled on the vertical connection beam 10 as necessary.

The main frame 100 includes a vertical frame 110 having a truss structure, a parallel transverse frame 120, and a connection frame 130 connecting the parallel transverse frame 120 for convenience.

If the longitudinal frame 110 is a simple beam form, the greater the distance from the seat frame 200 due to the load of the seat frame 200 and the occupant connected thereto, the greater the bending moment acting on the longitudinal frame 110 occurs In order to support this, the weight of the member is increased.

However, when the truss-shaped frame is applied, the moment is not applied to the truss member, which is advantageous for the lightweight design which reduces the weight of the member.

The shape of the truss can be various shapes such as triangle or trapezoid, and the number and shape of the constituent members of the truss can also be varied.

Figure 1 shows a truss shape with a relatively simple and symmetrical shape of the configuration member.

The longitudinal frame 110 of the truss structure is connected to the lower elastic truss member 111, the lower fixed truss member 112, the terminal inclined truss member 113, the central inclined truss member 114, the upper truss member 115 The upper joint bracket 116, the intermediate joint bracket 117, the distal joint bracket 118 and the center joint bracket 119 and the like. In the exemplary embodiment shown in the drawing, the longitudinal frame 110 includes two lower elastic truss members 111, a lower fixed truss member 112, a terminal inclined truss member 113, and a central inclined truss member 114, respectively. Although illustrated, the number may vary according to specific embodiments of the present invention. In addition, although the upper joint bracket 116, the intermediate joint bracket 117, and the distal joint bracket 118 are respectively shown in the drawing to connect these members to each other, the structure or number of the brackets may vary depending on the embodiment. .

The lower half of the vertical connection beam 10 is formed with a slit 11 to prevent interference when the longitudinal frame 110 of the truss structure rotates, and may be partially reinforced by the reinforcing plate 15.

A roller or a sliding member may be attached to a portion of the slit 11 that may contact the longitudinal frame 110 of the truss structure.

The longitudinal frame 110 and the parallel transverse frame 120 of the truss structure may correspond to various working conditions and may have a flexible structure to reduce the volume during transport.

The parallel transverse frame 120 is telescopically expandable as shown in FIG. 1.

As shown in FIG. 2, the longitudinal frame 110 of the truss structure has a pin hole formed at one end of the inclined truss member 113 and pin holes of a plurality of chain links 102 formed at the other end thereof, and a lower stretch truss. Since a plurality of pin holes are also formed in the member 111, stepwise by selecting the fastening pin holes when pinning them to the pin holes of the upper joint bracket 116, the intermediate joint bracket 117 and the distal joint bracket 118. Adjustable length

The end slant truss member 113 is always used because the tensile force acts as a chain link 102, when the length of the end slant truss member 113, the extra chain link 102 is the upper truss member 115 Can be stored in the inner space.

If the overall shape of the truss is triangular, since the members connected to the end slope members form a straight line, only a plurality of pin holes need to be provided, and a chain link is not necessary.

A pair of seat frames 200 are rotatably assembled at both ends of the longitudinal frame 110 of the truss structure, and the seat frame 200 is provided with a seat and a safety bar, and the seat frame angle control means 210. The connection angle can be controlled.

A pair of rotating shafts are provided at the ends of the parallel frame 120 to form a rotating joint rotatably connected to the pair of connecting rods 140.

The other end of the pair of connecting rods 140 is rotatably connected to one mounting table 300 in parallel, and the connecting rod angle control means 310 between the connecting frame 130 and the connecting rod 140. Is equipped.

Although not shown, instead of the rotary joint connecting the pivot shaft and the connecting rod 140 at the end of the parallel transverse frame 120, a dual rotary joint capable of simultaneously rotating the pivot shaft and the connecting rod central axis may be applied. In this way, the connection angle between the connecting rod 140 and the rotating shaft can be variously designed.

The axis reinforcement bar 150 has one end connected to the bracket of the vertical connection beam 10 and the other end rotatably connected to the rotation shaft 131 provided at the extension line of the main rotation shaft on the connection frame 130. Most of the load to act as a moment in the parallel frame to support the large load is replaced by the tensile force to the axis reinforcing bar 150 is very helpful in the lightweight design .

Since the axis reinforcing bar 150 always acts only a tensile force, it is possible to replace all or part of it with a flexible material such as a rope, a chain or a belt. This can provide convenience when there is a joint deformation of the vertically connected beam 10.

Here, the reinforcing bar connection bracket 132 may be integrated with the axis reinforcing bar 150.

The central axis of the rotation shaft 131 is the same axis as the central axis of the pre-competition shaft 50.

Although not shown, it may be provided with a length adjusting means for finely adjusting the length in any one or the connection portion of the axis reinforcement bar 150, which can give an optimal tension to the axis reinforcement bar 150. It can be a means of giving a function.

In the first embodiment, the seat frame 200 and the connecting rod 140 is configured to be disassembled and assembled for the convenience of transportation.

The vertical connection beam 10 can also be disassembled and assembled by connecting the upper and lower parts with two connecting pins, and can be conveniently used when transporting since only one pin can be disassembled and moved like a joint.

Although not shown, the seat frame 200 and the connecting rod 140 may also have a joint structure as necessary.

3 illustrates a case where a plurality of planar reinforcement bars 160 and inclined reinforcement bars 170 are further installed in the main frame 100 of the first embodiment of the present invention, and the rest are the same as those of FIG. 1.

By adding the reinforcing bars 160 and 170 as described above, the strength and stiffness of the mainframe 100 can be effectively increased while increasing a little weight.

4 illustrates an improved design method of one side of the parallel transverse frame 120, a connecting rod 140 rotatably assembled therewith, and a loading table 300 rotatably connected thereto. It is showing.

A part of the parallel transverse frame 120 has a truss structure, a transverse frame axis 122 and a conical housing 123 relative to the horizontal frame axis 122, an arm nut 124 having an arm protruding from one side, and a transverse parallel truss. The truss structure is completed as the assembly member 125 to be fastened to the member 121, in which the special point is to accommodate the celebration housing 123 capable of oscillating motion in the truss structure.

Although the cross-section of the parallel frame 120 is generally a planar structure such as AA, the present invention also considers a three-dimensional structure having a plurality of transverse parallel truss members 121, such as the cross-section A'-A ', which is the main frame This is to maintain the strength and stiffness of the parallel transverse frame 120 above the required level even when the entire rotation of the 100 is inclined with respect to the large pivot shaft 50.

The parallel transverse frame 120 may have a telescopic structure even in a structure having a plurality of lateral parallel truss members 121.

The celebration housing 123 includes a connection rod 140 having a truss structure.

Stack main frame 301 also has a truss structure, the stack main frame truss member 302,

Comprised of the mounting shaft 303, the mounting shaft housing 304, the arm nut 305 and the assembly member 306 is similar to the parallel transverse frame 120, corresponding to the acting axial force The thrust bearing 307 is further applied.

Thrust bearings can also be applied to the horizontal frame shaft 122 as necessary.

It is preferable to apply a bearing of an appropriate type and size between the horizontal frame shaft 122 and the shaft housing 123 and the mounting shaft 303 and the mounting shaft housing 304.

The mounting pedestal housing 304 includes a lower connection rod 141 of the truss structure, the lower connection rod 141 may be assembled with the connection rod 140, if necessary, the connection rod 140 ) And the lower connection rod 141 may be integrated.

5 shows an improved design of the connecting frame 130 as the truss structure is applied to the parallel transverse frame 120.

The connecting frame truss member 133 connects the connecting frame 130 and the parallel transverse frame truss member 121 to make it more structurally strong, and through the pivot shaft 131 provided in the connecting frame 130, the axis line. Reinforcement bar 150 allows to support the load.

The parallel transverse frame 120, the mounting frame main frame 301 and the connecting frame 130 may be a whole or part of the truss structure, if necessary, may also be a variety of truss shape.

The roof work device having the truss frame configured as described above may have a light and durable structure. When the angle of the main frame 100 is adjusted to the inclination of the roof, the two seat frames 200 and the two mounting tables 300 may be used. The position can be kept in sync with the slope so that two workers can perform the roofing work at the optimum working position.

The present invention can be used in the industry to install, dismantle and repair the roof of various buildings.
