Technical Field

[0001] This utility model relates to the field of auxiliary support technology for pull arm systems, and more specifically, to an auxiliary support mechanism for a pull arm superstructure system. Background Technology

[0002] A hooklift truck, also known as a hooklift garbage truck, is a commonly used type of detachable truck that combines self-unloading of goods and automatic loading and unloading of the container. It consists of a hooklift driven by a hydraulic cylinder, and the garbage container is typically attached to a hook at one end of the hooklift. However, existing technology has the following shortcomings in its use:

[0003] When the boom and the box are rotated by two hydraulic cylinders, the hydraulic cylinders need to withstand a large force. Relying solely on the support of the hydraulic cylinders may not guarantee the stability of the boom during movement, and there are often no auxiliary support mechanisms on the vehicle body.

[0004] Therefore, there is an urgent need for an auxiliary support mechanism for the boom superstructure system to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that when the arm and the body are rotated by two hydraulic cylinders, the hydraulic cylinders need to withstand a large force, and the stability of the arm during the movement may not be guaranteed by the hydraulic cylinders themselves alone, while the vehicle body often does not have an auxiliary support mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An auxiliary support mechanism for a boom superstructure system is provided to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] An auxiliary support mechanism for a boom lift system includes a vehicle body. A first U-shaped block and two symmetrically distributed second U-shaped blocks are fixedly connected to the top of the vehicle body. A boom lift body is hinged to the first U-shaped block. Fixing blocks are fixedly connected to opposite side surfaces of the boom lift body. A hydraulic cylinder is hinged between the second U-shaped blocks and the fixing blocks.

[0031] Example:

[0032] like Figure 1-4 As shown, the auxiliary support mechanism of the boom lift system proposed in this embodiment includes a vehicle body 1. A first U-shaped block 2 and two symmetrically distributed second U-shaped blocks 3 are fixedly connected to the top of the vehicle body 1. A boom lift body 4 is hinged to the first U-shaped block 2. Fixing blocks 5 are fixedly connected to the opposite two sides of the boom lift body 4. A hydraulic cylinder 6 is hinged between the second U-shaped block 3 and the fixing blocks 5. A first fixing plate 7 is fixedly connected to the top of the vehicle body 1. A reciprocating motor 8 is fixedly installed on one side of the first fixing plate 7. A lead screw 9 is fixedly connected to the output end of the reciprocating motor 8. A bearing plate 10 is threadedly connected to the lead screw 9. Two guide rods 11 are fixedly connected to the first fixing plate 7. An installation opening 12 is opened on the upper surface of the bearing plate 10. A first support wheel 13 is rotatably connected in the installation opening 12. Two second support wheels 14 are installed at the bottom of the bearing plate 10.

[0033] The reciprocating motor 8 is electrically connected to the vehicle's control power supply. When the two hydraulic cylinders 6 are working, the hydraulic cylinders 6, the first U-shaped block 2, the second U-shaped block 3, and the fixed block 5 work together to drive the pull arm body 4 to rotate, increasing the angle between the pull arm body 4 and the vehicle body 1. At the same time, the reciprocating motor 8 is started, which drives the lead screw 9 to rotate. The rotating lead screw 9 drives the bearing plate 10 to move closer to the second fixed plate 15, so that the first support wheel 13 on the bearing plate 10 contacts the outer surface of the pull arm body 4. Through the cooperation of the first support wheel 13, the bearing plate 10, and the two second support wheels 14, auxiliary support for the pull arm body 4 can be achieved, reducing the force on the two hydraulic cylinders 6 and ensuring the stability of the pull arm body 4 during movement, which helps to extend the service life of the hydraulic cylinders 6.

[0034] like Figure 1 and Figure 2 As shown, a second fixed plate 15 parallel to the first fixed plate 7 is fixedly connected to the top of the main body 1 of the vehicle plate. The end of the lead screw 9 away from the reciprocating motor 8 is rotatably connected to the second fixed plate 15 through a bearing.

[0035] The bearings are designed to ensure the stability of the lead screw 9 during rotation.

[0036] like Figure 1 and Figure 3 As shown, the two fixed blocks 5 and the two hydraulic cylinders 6 are symmetrically distributed about the central axis of the arm body 4, and the hydraulic rod end of the hydraulic cylinder 6 is hinged to the fixed block 5.

[0037] When the hydraulic cylinder 6 is running, it can drive the main body 4 of the pull arm to rotate.

[0038] like Figure 1 and Figure 2 As shown, the two guide rods 11 are symmetrically distributed about the central axis of the lead screw 9. The end of the guide rod 11 away from the first fixed plate 7 is fixedly connected to the second fixed plate 15. The bearing plate 10 is slidably sleeved on the two guide rods 11.

[0039] The two guide rods 11 can guide the support plate 10 and prevent the support plate 10 from shifting its position during movement.

[0040] like Figure 1 and Figure 4 As shown, the two second support wheels 14 are symmetrically distributed about the central axis of the bearing plate 10, and the second support wheels 14 are in rolling contact with the upper surface of the vehicle body 1.

[0041] The two second support wheels 14 can evenly transfer the force on the first support wheel 13 and the bearing plate 10 to the vehicle body 1, reducing the situation of excessive local stress.

[0042] like Figure 1 and Figure 2 As shown, a hook 16 is installed on the side end of the pull arm body 4 away from the first U-shaped block 2.

[0043] Garbage containers are typically attached to hooks 16 installed at one end of the boom.

[0044] like Figure 4 As shown, the first support wheel 13 and the second support wheel 14 are parallel.

[0045] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
