Detailed implementation manners

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , a crawler transporter for facilitating the shipment of heavy goods, comprising a crawler vehicle 1, a base 2 and a cargo box 3. The base 2 is fixed at the top of the crawler vehicle 1. The cargo box 3 is arranged above the base 2. The front end of the cargo box 3 is hinged to the front end of the base 2. A hydraulic rod 4 is rotatably connected to the top end of the base 2. The other end of the hydraulic rod 4 is rotatably connected to the bottom end of the cargo box 3. When the hydraulic rod 4 is lifted, the rear end of the cargo box 3 rises. A lifting mechanism for lifting goods is arranged on the cargo box 3. The lifting mechanism comprises two sliding rails 5. The two sliding rails 5 are respectively arranged on the inner walls on both sides of the cargo box 3. A threaded rod 6 is rotatably connected in the sliding rail 5. One end of the threaded rod 6 passes through the cargo box 3 backward. Two first motors 7 are installed at the rear side of the cargo box 3. The output end of the first motor 7 is fixed to the threaded rod 6 on the same side. A sliding block 8 is slidably connected in the sliding rail 5. The sliding block 8 is threadedly connected to the threaded rod 6. A lifting block 9 is rotatably connected to one side of the sliding block 8 close to the center of the cargo box 3. A clamping block 10 is fixed on the side wall of the sliding block 8. The clamping block 10 contacts the front end of the lifting block 9. A limiting column 11 is fixed at the front end position of the sliding rail 5. The limiting column 11 can contact the front end of the lifting block 9.

[0022] When this crawler transporter is in use and needs to load heavy goods, the hydraulic rod 4 is activated. The hydraulic rod 4 extends, pushing the rear end of the car body 3 to lift. In the initial state, the sliding block 8 is located at the front end of the car body 3. The lifting block 9 is rotated to contact the clamping block 10. Under the action of the clamping block 10, the lifting block 9 cannot rotate forward anymore. The goods are placed on the car body 3 and come into contact with the lifting block 9. The first motor 7 is activated to drive the threaded rod 6 to rotate. The sliding block 8 threadedly connected to the threaded rod 6 drives the lifting block 9 to move along the sliding rail 5 towards the rear end of the car body 3. The lifting block 9 lifts the goods and moves them towards the rear end of the car body 3. The threaded rod 6 is rotated in the reverse direction again to move the lifting block 9 to the front end of the car body 3. This process is repeated until the car body 3 is filled with goods. Then, the hydraulic rod 4 is contracted to make the car body 3 horizontal. At the same time, the lifting block 9 plays a role in fixing the goods. When unloading, the first motor 7 is activated to make the sliding block 8 move forward along the sliding rail 5. While moving, the front end of the lifting block 9 contacts the limit post 11. Under the action of the limit post 11, the lifting block 9 rotates and disengages from the clamping block 10 and contacts the side wall of the sliding block 8. The lifting block 9 is located within the sliding rail 5. Then, the hydraulic rod 4 is extended again to lift the rear end of the car body 3, facilitating unloading.

[0023] In actual use, it is found that when loading some small items such as sand, the sliding rail 5 will be blocked, affecting subsequent use. To avoid the above problems, in this embodiment, two first baffle plates 12 are rotatably connected to the inner bottom wall of the car body 3, and the two first baffle plates 12 are symmetrically distributed left and right.

[0024] In actual use, it is found that when the first baffle plate 12 is lifted and contacts the inner wall of the car body 3, there is no limit and positioning, and it will rotate, affecting the loading of goods. To solve the above problems, in this embodiment, two limit blocks 13 are symmetrically arranged at the rear end of the car body 3, and the two limit blocks 13 are rotatably connected to the car body 3.

[0025] In actual use, it is found that the lifting block 9 will slip when contacting the goods. To avoid the above problems, in this embodiment, a strip-shaped anti-slip protrusion 14 is provided at the rear end of the lifting block 9.

[0026] In actual use, it is found that under the action of force, the sliding block 8 may shift, causing the threaded rod 6 to deform. To avoid the above problems, in this embodiment, the sliding rail 5 is provided in a cross shape, and the sliding block 8 is adapted to the sliding rail 5.

[0027] In actual use, it is found that the amount of goods that can be loaded is small. To increase the loading capacity, in this embodiment, two clamping chute grooves 15 are symmetrically opened at the front end of the car body 3, and a second baffle plate 16 is slidably connected to the two clamping chute grooves 15.
