A kind of miniature no-dig technique horizontal directional drilling machine chassis ridgepole luffing structure
Technical field
The invention belongs to luffing structures, are more particularly to a kind of miniature no-dig technique horizontal directional drilling machine chassis ridgepole luffing knot
Structure.
Background technique
In no-dig technique drilling machine, chassis ridgepole jib lubbing mechanism is a very crucial structure, and crossbeam is horizontal when walking, when work
Chassis fixation is worked by crossbeam with different angle of penetration.Previous jib lubbing mechanism change angle is big but structure is complicated, needs
Two groups of front and back amplitude oil cylinder and individual chassis support leg mechanism.
Summary of the invention
The object of the present invention is to provide a kind of relatively simple novel luffing structures of structure.
According to an aspect of the invention, there is provided a kind of miniature no-dig technique horizontal directional drilling machine chassis ridgepole luffing knot
Structure, comprising:
Support frame,
Chassis, installs the bottom of support frame as described above, and the rotation on the chassis drives the movement of support frame as described above, the chassis
On be fixedly installed pedestal,
The bottom of rear support leg, one end and support frame as described above is rotatably connected,
Amplitude oil cylinder, cylinder body are rotatably connected with the rear support leg,
One end of crossbeam, the pedestal is fixedly connected with support frame as described above, and the other end of the pedestal and the crossbeam can
Rotation connection, the telescopic rod of the amplitude oil cylinder are rotatably connected with the crossbeam,
When the telescopic rod of the amplitude oil cylinder does not stretch out the cylinder body, the free end of the rear support leg is for hanging
State, the crossbeam are set in parallel with ground, described when gradually stretching out the cylinder body with the telescopic rod of the amplitude oil cylinder
Rear support leg moves closer to ground until support is in ground, and the angle that the crossbeam is formed with ground is gradually increased.
In some embodiments, the pedestal includes three connecting rods, and one end of three connecting rods is fixed respectively
On the upper surface of support frame as described above, the other end of three connecting rods converges to be rotatably connected with the crossbeam.
In some embodiments, the chassis is at least provided with two.
In some embodiments, the rear support leg and the one end of ground face contact are equipped with contact disc.
Its advantages: crossbeam and support frame are for parastate when walking by the present invention, and when work, rear support leg will be filled
Fixation is set, as the telescopic rod of amplitude oil cylinder gradually stretches out cylinder body, the angle on crossbeam and ground is gradually increased, until required angle
Degree, the configuration of the present invention is simple, need to only adjust amplitude oil cylinder can make crossbeam bury work with preset angle.

Specific embodiment
Fig. 1 and Fig. 2 schematically shows the miniature no-dig technique horizontal directional drilling machine bottom of one embodiment of the present invention
Disk crossbeam luffing structure.As depicted in figs. 1 and 2, which includes: branch
Support 1, chassis 2, rear support leg 3, amplitude oil cylinder 4 and crossbeam 5.
The bottom of support frame 1 is installed on chassis 2, and chassis 2 is at least provided with two.With guarantee the more firm walking of device and
Work.The rotation on chassis 2 drives the movement of support frame 1, is fixedly installed pedestal 6 on chassis 2.One end of rear support leg 3 and branch
The bottom of support 1 is rotatably connected.Specifically, one end of rear support leg 3 is rotatably connected by shaft and the bottom of support frame 1
It connects.Rear support leg 3 and the one end of ground face contact are equipped with contact disc 31.The surface area of contact disc 31 is greater than the table of rear support leg 3
Area buffers contact of the rear support leg 3 with ground, plays the role of protection.The cylinder body 41 and rear support leg 3 of amplitude oil cylinder 4 can
Rotation connection.Specifically, the cylinder body 41 of amplitude oil cylinder 4 is rotatably connected by shaft with rear support leg 3.One end of pedestal 6 with
Support frame 1 is fixedly connected, and the other end and the crossbeam 5 of pedestal 6 are rotatably connected.Specifically, the other end of pedestal 6 by shaft with
Crossbeam 5 is rotatably connected.Pedestal 6 includes three connecting rods 61, and one end of three connecting rods 61 is separately fixed at the upper of support frame 1
On surface, the other end of three connecting rods 61 converges to be rotatably connected with crossbeam 5.Specifically, three connecting rods 61
The other end is rotatably connected by shaft with crossbeam 5.It is stably mounted at crossbeam 5 more on support frame 1.Luffing oil
The telescopic rod 42 of cylinder 4 is rotatably connected with crossbeam 5.Specifically, the telescopic rod 42 of amplitude oil cylinder 4 can be turned by shaft with crossbeam 5
Dynamic connection.When the telescopic rod 42 of amplitude oil cylinder 4 does not stretch out cylinder body 41, the free end of rear support leg 3 is for vacant state, greatly
Beam 5 is set in parallel with ground, and when gradually stretching out cylinder body 41 with the telescopic rod 42 of amplitude oil cylinder 4, rear support leg 3 is moved closer to
Until support is in ground, the angle that crossbeam 5 is formed with ground is gradually increased on ground.
As shown in Figure 1, the present invention when walking crossbeam 5 and support frame 1 for parastate.As shown in Fig. 2, the present invention exists
When work, rear support leg 3 fixes device, as the telescopic rod 42 of amplitude oil cylinder 4 gradually stretches out cylinder body 41, crossbeam 5 and ground
Angle α gradually increase, until required angle, the configuration of the present invention is simple, need to only adjust amplitude oil cylinder 4 can make crossbeam 5 with
Preset angle is buried work.
The above are merely some embodiments of the present invention.For those of ordinary skill in the art, this is not being departed from
Under the premise of innovation and creation are conceived, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.
