Description

Technical Field

[0001] This utility model relates to the field of hooklift truck technology, and in particular to a rear support structure for a hooklift truck and a hooklift truck. Background Technology

[0002] Hooklift trucks, also known as detachable garbage trucks, are a highly efficient garbage transfer tool. They utilize a fully hydraulic control system, allowing the garbage container to be completely separated from the chassis. They offer advantages such as a reasonable structure, simple and stable operation, good sealing performance, and convenient dumping. Hooklift trucks can easily achieve combined operation of one truck with multiple garbage containers for cyclical transportation, greatly improving the vehicle's transport capacity and garbage disposal efficiency, making them an important piece of equipment for modern urban waste management.

[0003] The existing hooklift truck rear support structure usually includes a rotatable support roller and a hydraulic cylinder that drives the support roller to move. The support roller flips to the support position to support the rear end of the hooklift truck. Since hooklift trucks work in different working environments and road conditions vary, some road surfaces are uneven or have a certain slope. Therefore, the distance between the support roller and the road surface during use will have a certain height difference from the design.

[0004] When the distance between the support rollers increases, the impact of the garbage bins as they are loaded onto the hooklift truck causes a significant vertical displacement of the support rollers. This results in considerable swaying of the hooklift truck and a substantial radial impact force on the bearings connecting the support rollers. Over time, this leads to faster bearing wear, reduced bearing lifespan, and in severe cases, bearing deformation, thus degrading the rolling performance of the support rollers. Conversely, when the distance decreases, the support rollers may collide with the ground structure. Therefore, the existing rear support structure of hooklift trucks has poor adaptability to different working environments. Utility Model Content

[0005] This application provides a rear support structure for a hooklift truck to improve the adaptability of the rear support rollers to different road conditions. This application also provides a hooklift truck.

[0006] The first aspect of this application provides a rear support structure for a hooklift truck, comprising:

[0007] Connecting bracket, for connection to the vehicle frame;

[0008] The drive shaft is rotatably connected to the connecting seat;

[0009] A drive component is connected between the vehicle frame and the drive shaft, and the drive component is used to drive the drive shaft to rotate;

[0026] Example 1

[0027] like Figure 1 As shown, a hooklift truck rear support structure includes: a connecting seat 1, a drive shaft 2, a drive component 3, a connecting plate 4, a slider 5, a support roller 6, and an adjustment mechanism 7. The connecting seat 1 is connected to the vehicle frame 8. The drive shaft 2 is rotatably connected to the connecting seat 1. The drive component 3 is connected between the vehicle frame 8 and the drive shaft 2 and is used to drive the drive shaft 2 to rotate. The connecting plate 4 is connected to the drive shaft 2. The connecting plate 4 has a groove 401 along its length. The slider 5 is slidably disposed in the groove 401. The support roller 6 is rotatably connected to the slider 5. The adjustment mechanism 7 connects the slider 5 to the connecting plate 4 and is used to adjust the position of the slider 5.

[0028] Specifically, such as Figure 1As shown, there are two connecting seats 1, which are symmetrically arranged on the bottom rear end of the frame 8. The connecting seats 1 are connected to the frame 8 by bolts. The drive shaft 2 is located between the two connecting seats 1. The two ends of the drive shaft 2 are equipped with first shaft bodies 201, which are rotatably connected to the connecting seats 1. There are two connecting plates 4. Each first shaft body 201 is fitted with a connecting plate 4. The connecting plates 4 are connected to the corresponding end faces of the drive shaft 2 by bolts. The other end of the connecting plate 4 is provided with a sliding groove 401, which is a through hole. The inner wall of the sliding groove 401 is equipped with a guide strip 402. The slider 5 is equipped with a guide groove corresponding to the guide strip 402. The slider 5 is slidably set on the guide strip 402 through the guide groove. The slider 5 is separated into two plates at the guide groove position. The plates are connected by bolts. The assembly operation of the slider 5 and the guide groove is achieved in this way. A second shaft body 9 is also connected between the two connecting plates 4. The support roller 6 is rotatably fitted on the outer periphery of the second shaft body 9.

[0029] Specifically, such as Figure 1 As shown, a lug 202 extends outward from the middle of the drive shaft 2. The drive component 3 is hinged to the lug 202. There are two lugs 202, which are spaced apart. A third shaft 10 is installed between the lugs 202. The drive component 3 is a hydraulic cylinder. The upper end of the cylinder body is connected to the mounting seat 11 by bolts. The mounting seat 11 is hinged to the frame 8. The end of the hydraulic cylinder piston rod is fitted onto the third shaft 10, thereby realizing the assembly of the hydraulic cylinder with the frame 8 and the drive shaft 2.

[0030] Specifically, such as Figure 1 As shown, the adjustment mechanism 7 includes: an adjustment rod 701, which is threadedly connected to the connecting plate 4 and rotatably connected to the slider 5. The adjustment rod 701 is a screw. A connecting block 12 is welded to the outer surface of the connecting plate 4. The connecting block 12 has a threaded hole corresponding to the adjustment rod 701. The adjustment rod 701 is threadedly connected to the connecting block 12. One end of the adjustment rod 701 has a regular hexagonal block. The operator drives the block to move by using a wrench. The other end of the adjustment rod 701 has a ball end. The upper end of the slider 5 has a hemispherical groove that matches the shape of the ball end. The upper end of the slider 5 is also connected to a pressure cap 13. The pressure cap 13 has an arc-shaped through hole corresponding to the ball end. The through hole and the groove form a limiting structure for the ball end. The ball end is rotatably set in the limiting structure.

[0031] Specifically, such as Figure 1 As shown, the adjustment mechanism 7 also includes an anti-loosening component 702, which is disposed between the adjustment rod 701 and the connecting plate 4. The anti-loosening component 702 adopts a hexagonal flange nut, which tightens the connecting block 12 to achieve the anti-loosening effect. In addition, a double nut structure can also be used for anti-loosening.

[0032] Specifically, such as Figure 1 , 2As shown, in use, the rear support structure of this hooklift truck applies external force to the drive shaft 2 through the drive component 3, causing the support roller 6 to move to the support position or to the folded position. When it is necessary to adjust the height position of the support roller 6, the operator uses a wrench to loosen the anti-loosening component 702 and drives the adjusting rod 701 to rotate, thereby causing the slider 5 to slide in the slide groove 401, thus changing the height position of the support roller 6, so that the support roller 6 can better match the working environment, avoid the support roller 6 being too far or too close to the ground, and improve the ease of use and environmental adaptability of this hooklift truck rear support structure.
