Abstract
The utility model pertains to the crane mechanic technology field and discloses a tyre crane. The utility model comprises a bodywork which is provided with an elevator boom composed of a plurality of box arms and a landing leg with outer thimble. The elevator arm is provided with steel ropes controlled by hydro press. The hydro press is provided with a balance valve. The utility model has the advantages of even-pace rise and fall, good stable performance, accurate positioning and safe and labor-saving operation.
Description
Technical field
The utility model belongs to the elevator machinery technical field, relates in particular to a kind of wheel-mounted crane.
Background technology
In the inaccessiable narrow occasion of goliath, originally use mostly and lead chain, not only time-consuming but also require great effort.Quick for convenience, people are arranged on crane arm and supporting leg on the four-wheeled, developed wheel-mounted crane, wheel-mounted crane is littler many than goliath volume, and need not re-use the bogie transportation, the alleyway in many narrow occasions such as rural area, wheel-mounted crane can both pass in and out flexibly, and is very easy to use.But, presently used wheel-mounted crane, because hoist rope is hoisting, is all adopting in the falling process brake control sinking speed, thereby stability is not high, is difficult to realization and at the uniform velocity rises and falls; There is the gap in the end that respectively saves the box-shaped arm of crane arm, makes crane arm easily produce side-bend in the course of the work, position error occurs; The joint of steel rope adopts the dop clamping type, makes the joint easily thread off, and forms accident potential; When withdrawing X type supporting leg, because supporting leg and its outer tube friction force are bigger, withdrawing is required great effort very much.
The utility model content
The purpose of this utility model just provides a kind of stability height, accurate positioning, labour-saving safe in utilization wheel-mounted crane.
The technical solution adopted in the utility model is: comprise car body, car body is provided with the crane arm that is made of some joint box-shaped arms and has the supporting leg of outer tube, and crane arm is provided with the steel rope that is subjected to hydraulic compressor control, and described hydraulic compressor is provided with balance cock.
Its additional technical feature is: the terminal medial surface vertical direction of described box-shaped arm is provided with limiting stopper; Described limiting stopper is symmetrically arranged two; The joint of described steel rope adopts the formula of inserting of compiling; The lower end of the outlet of described supporting leg outer tube is provided with sliding roller.
Wheel-mounted crane provided by the utility model compared with prior art has the following advantages: one, be provided with balance cock on the hydraulic compressor of control steel rope, make the hydraulic compressor stable output power, hoisting, falling after rise of steel rope need not be again by brake control, improved stability, steel rope can at the uniform velocity be risen and fallen; Its two, each terminal medial surface vertical direction that saves the box-shaped arm is symmetrical arranged two limiting stoppers, makes the end respectively save the box-shaped arm no longer have the gap, crane arm no longer produces side-bend, accurate positioning in the course of the work; Its three, the joint of steel rope adopts compiles the formula of inserting, the joint is dragged tighter and tighter, can not occur threading off again, safety performance improves greatly; Its four, the lower end of the outlet of supporting leg outer tube is provided with sliding roller, the supporting leg withdrawing is to rotate by sliding roller when going out outer tube, greatly reduces friction force, uses very laborsaving.
Description of drawings
Fig. 1 is the structural representation of the utility model wheel-mounted crane;
Fig. 2 is the structural representation of hydraulic compressor;
Fig. 3 is the structural representation of wireline adapter;
Fig. 4 is the structural representation of box-shaped arm;
Fig. 5 is the structural representation of supporting leg.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of the drawings and specific embodiments the utility model wheel-mounted crane.
As shown in Figure 1, the utility model wheel-mounted crane comprises car body 1, and car body 1 is provided with crane arm 3 that is made of some joint box-shaped arms 2 and the supporting leg 5 that has outer tube 4, and crane arm 3 is provided with the steel rope 7 that is subjected to hydraulic compressor 6 controls.As shown in Figure 2, hydraulic compressor 6 is provided with balance cock 8.As shown in Figure 3, the joint 9 of steel rope 7 adopts the formula of inserting of compiling.As shown in Figure 4, the terminal medial surface vertical direction of box-shaped arm 2 is symmetrically arranged with two limiting stoppers 10.As shown in Figure 5, the lower end of the outlet of the outer tube 4 of supporting leg 5 is provided with sliding roller 11.
When wheel-mounted crane provided by the utility model uses, be arranged on hoisting, falling after rise of balance cock 8 control steel ropes 7 on the hydraulic compressor 6, make hydraulic compressor 6 stable output power, improved the stability of wheel-mounted crane, steel rope 7 can at the uniform velocity be risen and fallen.The terminal medial surface vertical direction of box-shaped arm 2 is symmetrical arranged two limiting stoppers 10, makes the end that respectively saves box-shaped arm 2 no longer have the gap, and crane arm 3 no longer produces side-bend, wheel-mounted crane accurate positioning in the course of the work.The joint 9 of steel rope 7 adopts compiles the formula of inserting, and joint 9 places drag tighter and tighter, and threading off can not appear in steel rope 7 again, and the wheel-mounted crane safety performance improves greatly.The lower end of the outlet of the outer tube 4 of supporting leg 5 is provided with sliding roller 11, and supporting leg 5 withdrawings are to rotate by sliding roller 11 when going out outer tube 4, greatly reduce friction force, use wheel-mounted crane very laborsaving.
