[0001] This utility model relates to the field of tractor assembly technology, and in particular to a tractor chassis assembly loading device. Background Technology
[0002] A tractor is a self-propelled power machine used to traction and drive work machinery to complete various mobile tasks. It is widely used in rural areas of my country to replace manual labor in heavy tasks such as sowing and harvesting. Generally, the power output from the engine is reduced by the gearbox and then transmitted to the rear axle to drive the tractor to move and perform work. At present, many companies manufacture tractors by assembly. Therefore, in the tractor assembly workshop, the various parts of the tractor need to be assembled into several large components in batches, and then the several components are assembled and combined to finally complete the assembly of the tractor.
[0003] During the assembly of tractors, especially the chassis, the chassis is heavy and requires support and fixation by a carrier. However, existing tractor chassis carriers have a relatively simple structure and cannot ensure stability when bearing tractor chassis of different sizes, resulting in low practicality. Therefore, a tractor chassis assembly carrier is proposed to solve the above problems. Utility Model Content

The spacing adjustment mechanism can adjust the spacing between the two vertical rods, thereby adjusting the spacing between the two support plates, so that the two support plates can support tractor chassis of different lengths. It has the advantages of supporting and fixing tractor chassis of different sizes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] like Figure 1-6 As shown, the present invention proposes a tractor chassis loading device, including a base plate 1, two vertical rods 5 are arranged above the base plate 1, two support plates 2 are arranged above the two vertical rods 5, and a fixing structure 3 is arranged at the top of each of the two vertical rods 5. The two vertical rods 5 are respectively connected to the two support plates 2 through two sets of fixing structures 3. A spacing adjustment mechanism 4 is arranged at the top of the base plate 1, and the base plate 1 is connected to the vertical rods 5 through the spacing adjustment mechanism 4.
[0025] In this invention, two support plates 2 can support the left and right sides of the bottom of the tractor chassis respectively, and two vertical rods 5 and a fixing structure 3 can support the two support plates 2 respectively. After support, the fixing structure 3 can fix and limit tractor chassis of different widths, and the spacing adjustment mechanism 4 can adjust the spacing of the two vertical rods 5, thereby adjusting the spacing of the two support plates 2, so that the two support plates 2 can support tractor chassis of different lengths. With the cooperation of the fixing structure 3 and the spacing adjustment mechanism 4, tractor chassis of different sizes can be supported and fixed, ensuring the stability of the tractor chassis on the vehicle, and also facilitating the transportation of the tractor chassis.
[0026] like Figure 1-3 As shown, in an optional embodiment, the fixed structure 3 includes a U-shaped plate 31, two movable slots 32, two rotating rods 33, two fixed rods 34, a double-axis reciprocating cylinder 35, two movable blocks 36, two connecting rods 37, and two sets of T-shaped components 38. The U-shaped plate 31 is located at the bottom of the support plate 2. The two movable slots 32 are respectively opened on the front and back of the support plate 2. The top and bottom of the two movable slots 32 are connected to the outside. The two rotating rods 33 are rotatably connected to the inside of the two movable slots 32 by pins. The two fixed rods 34 are respectively located at the top of the two rotating rods 33. The double-axis reciprocating cylinder 35 is located on the inner bottom wall of the U-shaped plate 31. The two movable blocks 36 are respectively located on the two piston rods of the double-axis reciprocating cylinder 35. The two connecting rods 37 are respectively hinged to the opposite side of the two movable blocks 36 by pins. The other end of the two connecting rods 37 is respectively hinged to the bottom of the two rotating rods 33 by pins. The two T-shaped components 38 are respectively located at the bottom of the two movable blocks 36.
[0027] When supporting the tractor chassis, first adjust the distance between the two support plates 2 according to the length of the tractor chassis to match the length of the chassis. Then, place the tractor chassis on top of the two support plates 2. Next, start the dual-shaft double-acting cylinder 35. The two piston rods of the dual-shaft double-acting cylinder 35 will drive the two movable blocks 36 to move to opposite sides. The two movable blocks 36 will drive the ends of the two connecting rods 37 near the movable blocks 36 to move to opposite sides. Under the action of the pin, the other ends of the two connecting rods 37 will drive the two rotating rods 33 to move... The rotation causes the two rotating rods 33 to rotate to their opposite sides, which in turn drives the two fixed rods 34 to rotate to their opposite sides. When the opposite sides of the two fixed rods 34 abut against the front and back of the tractor chassis, the tractor chassis is fixed, ensuring its stability during transport. After transport is completed, the two fixed rods 34 are rotated to their opposite sides by reversing the operation of the dual-shaft double-acting cylinder 35, thus losing their fixation to the tractor chassis and allowing it to be removed from the support plate 2.
[0028] like Figure 2-3 As shown, in an optional embodiment, both T-shaped components 38 include a T-shaped groove 381 and a T-shaped block 382. The two T-shaped grooves 381 are both formed on the inner bottom wall of the U-shaped plate 31, and the two T-shaped blocks 382 are respectively disposed at the bottom of the two movable blocks 36. The two T-shaped blocks 382 are slidably connected to the inside of the two T-shaped grooves 381.
[0029] When the two movable blocks 36 move to the opposite side or away from each other, the T-slot 381 and T-block 382 can guide and limit the movable blocks 36, ensuring the stability of the movable blocks 36 during the movement and preventing the movable blocks 36 from tilting up during the movement.
[0030] like Figure 1 , Figure 4 and Figure 5 As shown, in an optional embodiment, the spacing adjustment mechanism 4 includes a fixed block 41, two mounting plates 42, a rotating rod 43, two threaded grooves 44, two threaded rods 45, a rotating handle 46, and a support assembly 47. The fixed block 41 is located on the top of the base plate 1, and the two mounting plates 42 are both located on the top of the fixed block 41. The rotating rod 43 is rotatably connected between the opposite sides of the two mounting plates 42 via bearings. The two threaded grooves 44 are respectively opened at both ends of the rotating rod 43, and the two threaded rods 45 are respectively rotatably connected to the inside of the two threaded grooves 44. The opposite ends of the two threaded rods 45 are respectively connected to the opposite sides of the two vertical rods 5. The support assembly 47 is located at the bottom of the vertical rods 5.
[0031] Before supporting the tractor chassis, the handle 46 needs to be rotated according to the length of the tractor chassis. Rotating the handle 46 will drive the rotating rod 43 to rotate, which in turn will drive the two threaded grooves 44 to rotate. Under the action of the threaded thrust, the two threaded grooves 44 will drive the two threaded rods 45 to move to the opposite side or the opposite side respectively. The two threaded rods 45 will drive the two vertical rods 5 to move to the opposite side or the opposite side respectively. Under the action of the fixed structure 3, the two vertical rods 5 will drive the two support plates 2 to move to the opposite side or the opposite side respectively, thereby adjusting the distance between the two support plates 2, so that the two support plates 2 can support tractor chassis of different lengths.
[0032] like Figure 1 , Figure 4 and Figure 6 As shown, in an optional embodiment, the support assembly 47 includes two horizontal plates 471, two guide blocks 472, two guide grooves 473, and four rollers 474. The two horizontal plates 471 are respectively located at the bottom ends of the two vertical rods 5. The two guide blocks 472 are both located at the top of the base plate 1. The two guide grooves 473 are respectively opened on the opposite side of the two guide blocks 472. The two ends of the two horizontal plates 471 are slidably connected to the inside of the two guide grooves 473. The four rollers 474 are respectively located at the bottom of the two horizontal plates 471 and are evenly distributed. The outer bottom of the four rollers 474 abuts against the top of the base plate 1.
[0033] When the two vertical rods 5 move to the opposite side or away from each other, they will drive the two horizontal plates 471 to move to the opposite side or away from each other. At this time, the two horizontal plates 471 will slide inside the two guide grooves 473. The two guide blocks 472 and the two guide grooves 473 can provide certain support and guidance for the horizontal plates 471, ensuring the stability of the movement of the horizontal plates 471. During the movement of the two horizontal plates 471, the rollers 474 can provide stable support for the horizontal plates 471, ensuring the stability of the horizontal plates 471, vertical rods 5 and support plates 2 when supporting the tractor chassis.
[0034] like Figure 1 As shown, in an optional embodiment, the bottom of the base plate 1 is provided with four evenly distributed movable wheels. The base plate 1 can be moved by the movable wheels, thereby moving the entire vehicle, and further moving the tractor chassis carried on the vehicle, facilitating the carrying and movement of the tractor chassis.
[0035] In addition, a battery is installed at the bottom of the base plate 1 and a controller is installed at the top of the base plate 1. The battery can supply power to the dual-axis double-acting cylinder 35 and the controller, and the controller can control the dual-axis double-acting cylinder 35.
[0036] Working principle:
[0037] Before using this tractor chassis loading device to support the tractor chassis, the handle 46 needs to be rotated according to the length of the tractor chassis. This causes the two vertical rods 5 to move to opposite sides. Under the action of the fixing structure 3, the two vertical rods 5 will respectively drive the two support plates 2 to move to opposite sides, thus adjusting the distance between the two support plates 2. This allows the two support plates 2 to support tractor chassis of different lengths. Then, the tractor chassis is placed on top of the two support plates 2, and the dual-axle double-acting cylinder 35 can be activated. The two piston rods of 5 will drive the two movable blocks 36 to move to opposite sides respectively. Under the action of the connecting rod 37, the two rotating rods 33 will rotate to their opposite sides respectively. The two rotating rods 33 will drive the two fixed rods 34 to rotate to their opposite sides respectively. When the opposite sides of the two fixed rods 34 abut against the front and back of the tractor chassis respectively, the tractor chassis can be fixed to ensure the stability of the tractor chassis during transportation. Then, the base plate 1 and the tractor chassis supported on it can be moved by the moving wheels to transport and assemble the tractor chassis.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
