Description

Technical Field

[0001] The utility model belongs to the field of line construction equipment, and more specifically, relates to a support adjustment mechanism for a tractor. Background Art

[0002] A tractor is a construction machine commonly used in the construction of overhead transmission lines and is used for the traction of conductors, ground wires, and optical cables in the tension stringing process. However, due to factors such as the fast rotation speed and small diameter of the drum in the current tractor, during the process of recovering old conductors, ground wires, and optical cables, the cable is likely to slip out of the drum, posing a great safety hazard.

[0003] Chinese Patent with the authorization announcement number CN209434777U discloses a cable tractor, which includes a cable drum, a drum mounting seat, and a base, and also includes a cable guiding mechanism and a cable drum guardrail. The top of the cable guiding mechanism is provided with a cable guiding frame, and the cable guiding frame includes a guiding seat, a rotating shaft installed on the guiding seat, and a sliding sleeve sleeved outside the rotating shaft and capable of rotating around it; the rotating shaft is parallel to the axis of the cable drum, and the cable drum guardrail includes a guardrail seat, a radial support rod, and an axial stop rod, and the axial stop rod is parallel to the axis of the cable drum.

[0004] The above technical solution has the following defects:

[0005] Similar to traditional tractors, when performing construction traction on cables, for its own stability, only the self-weight of the tractor realizes stability during traction, or it is fixed to the ground by means of anchoring. However, when two or more tractors are operating simultaneously, their stability still depends on their respective independent parts, and it is impossible to connect the tractors together to increase the overall stability. Summary of the Utility Model

[0006] In view of the above defects, the utility model provides a support adjustment mechanism for a tractor, including a tractor body, the tractor body includes a frame, wheels, and a traction roller. A front hydraulic cylinder is installed at the front end of the frame, two rear hydraulic cylinders are installed at the rear end of the frame, an L-shaped floor gripper is installed at the bottom end of the front hydraulic cylinder, and two stabilizing plate groups for reinforcement are movably installed at the bottom of the tractor body.

[0007] Furthermore, the stabilizing plate group includes a first stabilizing plate and a second stabilizing plate, and the first stabilizing plate and the second stabilizing plate are respectively installed on the left and right sides of the tractor body through movable mechanisms;

[0008] The movable mechanism includes two telescopic couplings respectively movably connected to the bottom ends of the left and right sides of the tractor body. Connecting arms are fixed to the bottom ends of the two telescopic couplings, and the two connecting arms are respectively connected to the first stabilizing plate and the second stabilizing plate.

[0009] With the above technical solution, when the independent tractor is in use, the first stabilizing plate and the second stabilizing plate are used overlappingly, and the stability between the tractor and the ground can be increased by adding an anchor.

[0010] When two or more tractors are used simultaneously, the first stabilizing plate or the second stabilizing plate is rotated to the outside and superimposed with the first stabilizing plate or the second stabilizing plate of another tractor, and the connection between two adjacent tractors is achieved through anchoring, so as to increase the dead weight to fix to the ground and achieve better stability.

[0011] Furthermore, both the first stabilizing plate and the second stabilizing plate are L-shaped, and meshing teeth adapted to each other are provided on the bending surfaces. The bottom near one end of the connecting arm is conical, and both the first stabilizing plate and the second stabilizing plate are provided with equally spaced anchoring holes.

[0012] With the above technical solution, through the L-shaped design, when the first stabilizing plate and the second stabilizing plate are used superimposedly, they fit more closely, and no protrusions will occur to affect the contact with the ground. The bending end is conical, and when the tractor displaces, it can hook with the ground to play a limiting role. The equally spaced anchoring holes can correspond to different lengths as needed and be fixed to the ground using an anchor.

[0013] Furthermore, two convex strips are fixed on the bending surface of the grounding plate.

[0014] With the above technical solution, the depth of insertion into the ground is increased.

[0015] The utility model has the following beneficial effects compared with the prior art:

[0016] When the tractor is used independently, the first stabilizing plate and the second stabilizing plate can be used superimposedly and located in the middle of the tractor, and the connection force with the ground is increased through anchoring to ensure the overall stability.

[0017] When two or more tractors are used simultaneously, the first stabilizing plate or the second stabilizing plate is rotated to the outside and superimposed with the first stabilizing plate or the second stabilizing plate of another tractor, and the connection between two adjacent tractors is achieved through anchoring, so as to increase the dead weight to fix to the ground and achieve better stability.

[0024] Embodiment

[0025] As Figures 1-3 shown, this embodiment provides a support adjustment mechanism for a tractor, including a tractor body 1. The tractor body 1 includes a frame, wheels, and a traction roller. A front hydraulic cylinder 3 is installed at the front end of the frame, and two rear hydraulic cylinders 2 are installed at the rear end of the frame. The bottom end of the front hydraulic cylinder 3 is installed with an L-shaped ground-gripping plate 4, and two ribs 5 are fixed on the bending surface of the ground-gripping plate 4. When the ground-gripping plate 4 is inserted into the ground, the depth of insertion into the ground can be increased. It should be noted that the bending angle value of the ground-gripping plate 4 is preferably between 60° and 75°, which can play a better role in hooking the ground, that is, when the tractor body 1 is displaced, it can be hooked with the ground to play a limiting role;

[0026] At the bottom of the tractor body 1, two stabilizing plate groups for reinforcement are also movably installed. The stabilizing plate group includes a first stabilizing plate 6 and a second stabilizing plate 8. The first stabilizing plate 6 and the second stabilizing plate 8 are respectively installed on the left and right sides of the tractor body 1 through movable mechanisms. The movable mechanism includes two telescopic couplings 71 respectively movably connected to the bottom ends of the left and right sides of the tractor body 1. In this embodiment, a universal coupling of model JB5513-91 is used. At the bottom ends of the two telescopic couplings 71, connecting arms 72 are fixed. The two connecting arms 72 are respectively connected to the first stabilizing plate 6 and the second stabilizing plate 8 and can be rotated as needed, which is convenient for stacking and using with another tractor body 1. When stacking, the telescopic couplings 71 expand and contract, so that there is enough space between the first stabilizing plate 6 and the second stabilizing plate 8 for the alignment of the meshing teeth 9, which is convenient for the fitting work after alignment.

[0027] Specifically, both the first stabilizing plate 6 and the second stabilizing plate 8 are L-shaped, and meshing teeth 9 are provided on the bending surfaces in a matching manner. The bottom of the end close to the connecting arm 72 is conical. This design will not produce protrusions during stacking use, will not affect the contact with the ground, and both the first stabilizing plate 6 and the second stabilizing plate 8 are provided with anchoring holes 10 distributed at equal distances, and different lengths can be selected according to needs for corresponding use, and they are fixed to the ground by anchoring (that is, when stacking and using with another tractor body 1, the distance between the two can be adjusted).

[0028] It should be noted that the structure of the present utility model can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other items, is included in the protection scope of the present utility model.
