Description

Technical Field

[0001] This utility model relates to the field of semi-trailer technology, specifically to a semi-trailer suspension assembly mechanism. Background Technology

[0002] To ensure the stability of semi-trailers during operation, existing semi-trailers generally use suspension as the core connecting component, connecting the frame at one end and the wheels at the other. This structure can not only effectively transfer and bear the weight of the vehicle itself, but also stably support the transported goods, providing key support for the smooth movement of the semi-trailer.

[0003] As the core component connecting the chassis and wheels, the semi-trailer suspension, through the design of elastic elements, has elastic support and shock absorption functions, giving the semi-trailer good dynamic load-bearing capacity and smooth driving. It can also buffer impacts and protect cargo in complex road conditions, making it a key technical link in ensuring transportation safety and stability and controlling cargo damage.

[0004] However, the existing blade spring frame assembly usually relies on manual installation onto the semi-trailer beam. Due to the strong elasticity of the spring frame itself, it is difficult for workers to quickly and accurately position it during the installation process. This not only makes the assembly operation time-consuming and labor-intensive, but also directly affects the overall assembly efficiency of the blade spring frame. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a semi-trailer suspension assembly mechanism that can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A semi-trailer suspension assembly mechanism, comprising: The semi-trailer body has two sets of main beams symmetrically arranged at the bottom. Two sets of support holes are symmetrically arranged at the bottom end of the main beams. Bolts are arranged inside the support holes. Mounting rings are inserted into the support holes. A spring frame is arranged at one end of the mounting ring. A base plate is arranged at the bottom of the spring frame. A steel beam is arranged inside the base plate and the spring frame. Axles are rotatably arranged at both ends of the steel beam. The mounting components include a lead screw, a rotating ring, and a support frame. Two sets of second threaded holes are evenly arranged at the bottom of the main beam. A lead screw is threaded inside the second threaded hole, and a rotating ring is rotatably arranged outside the lead screw. A connecting rod is provided at one end of the rotating ring, a limit block is rotatably arranged at one end of the connecting rod, and a support frame is provided at one end of the limit block. The limiting assembly includes a rotating rod, a sliding rod, and a threaded rod. Two sets of rotating rods are symmetrically arranged at the bottom of the main beam, and a sliding rod is slidably arranged on the inner side of the rotating rod.

[0007] Furthermore, a handle is provided at the outer end of the lead screw.

[0008] Furthermore, a limiting groove is provided at the bottom of the main beam, and a limiting block is slidably embedded inside the limiting groove.

[0009] Furthermore, the support frame engages with the mounting ring.

[0010] Furthermore, the sliding rod has a threaded rod on its inner side, and the base plate has a first threaded hole on its inner side, with the threaded rod screwed into the inner side of the first threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model include: When the spring frame needs to be assembled into the support hole, the worker first contacts the mounting ring on the spring frame with the bottom of the main beam, so that the mounting ring is located inside the support frame. Then, by turning the handle, the worker can drive the screw to screw into the inner side of the second threaded hole. Therefore, the connecting rod can drive the limiting block to move inside the limiting groove, so that the support frame drives the mounting ring to move into the inner side of the support hole. This makes it easy for the worker to fix the mounting ring inside the support hole with bolts, thus quickly fixing the spring frame. 2. After the spring frame is installed, the operator rotates the rotating rod and then pulls the sliding rod to align the threaded rod with the first threaded hole. The operator then screws the threaded rod into the first threaded hole to connect the sliding rod to the base plate. During the operation of the spring frame, the operation of the spring frame can be limited by the cooperation of the two sets of rotating rods, thereby preventing the multiple leaf springs inside the spring frame from shifting.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figure 1 - Figure 6 As shown, this utility model provides a semi-trailer suspension assembly mechanism, comprising: The semi-trailer body 100 has two sets of main beams 200 symmetrically arranged at its bottom. Two sets of support holes 605 are symmetrically arranged at the bottom end of the main beams 200. Bolts 604 are arranged inside the support holes 605. Mounting rings 603 are inserted into the support holes 605. A spring frame 601 is arranged at one end of the mounting ring 603. A base plate 602 is arranged at the bottom of the spring frame 601. A steel beam 400 is arranged inside the base plate 602 and the spring frame 601. Axles 300 are rotatably arranged at both ends of the steel beam 400. The mounting assembly 700 includes a lead screw 701, a rotating ring 703, and a support frame 705. Two sets of second threaded holes 708 are evenly provided at the bottom of the main beam 200. The lead screw 701 is threaded inside the second threaded hole 708, and the rotating ring 703 is rotatably provided on the outside of the lead screw 701. A connecting rod 702 is provided at one end of the rotating ring 703, and a limit block 706 is rotatably provided at one end of the connecting rod 702. The support frame 705 is provided at one end of the limit block 706. The limiting component 500 includes a rotating rod 501, a sliding rod 502, and a threaded rod 503. Two sets of rotating rods 501 are symmetrically rotatably arranged at the bottom of the main beam 200, and the sliding rod 502 is slidably arranged on the inner side of the rotating rod 501.

[0016] In the above scheme: 1. When installing the spring frame 601, the mounting ring 603 is placed inside the support frame 705, and then the control screw 701 is screwed into the second threaded hole 708. This allows the connecting rod 702 to drive the support frame 705 to move the mounting ring 603, so that the mounting ring 603 moves into the support hole 605, which facilitates the assembly of the spring frame 601 by the workers. 2. The movement of the limiting block 706 within the limiting groove 707 can drive the support frame 705 to move, thereby facilitating the installation of spring frames 601 of different specifications on the semi-trailer by the staff. 3. By cooperating with the rotating rod 501 and the sliding rod 502, the multiple sets of leaf springs in the spring frame 601 can be limited, thereby preventing the leaf springs from shifting.

[0017] In this embodiment, a handle 704 is provided at the outer end of the lead screw 701.

[0018] In the above solution: when the operator needs to adjust the lead screw 701, there is no need to use tools such as wrenches. He only needs to hold the grip section of the handle 704 with both hands and turn it clockwise or counterclockwise to drive the lead screw 701 to rotate.

[0019] In this embodiment, a limiting groove 707 is provided at the bottom of the main beam 200, and a limiting block 706 is slidably embedded in the inner side of the limiting groove 707.

[0020] In the above scheme: when the lead screw 701 drives the rotating ring 703 to rotate, the rotating ring 703 drives the connecting rod 702 to rotate. At this time, the top of the limiting block 706 slides inside the limiting groove 707. The limiting groove 707 can restrict the movement direction of the limiting block 706, so that it can only move along the length direction of the limiting groove 707, thus avoiding the lateral displacement of the limiting block 706.

[0021] In this embodiment, the support frame 705 engages with the mounting ring 603.

[0022] In the above scheme: when the staff positions the spring frame 601 using the installation component 700, the two sets of mounting rings 603 on the spring frame 601 are first attached to the inner arc surface of the corresponding support frame 705. The outer wall of the mounting ring 603 is in complete contact with the arc surface of the support frame 705, which facilitates the movement of the mounting ring 603.

[0023] In this embodiment, the inner side of the sliding rod 502 is provided with a threaded rod 503, and the inner side of the base plate 602 is provided with a first threaded hole 504, and the threaded rod 503 is screwed into the inner side of the first threaded hole 504.

[0024] In the above scheme: after the spring frame 601 is fixed to the main beam 200 by the mounting ring 603, the worker first rotates the rotating rod 501 so that it rotates around the hinge to a vertical state perpendicular to the base plate 602, and then pulls the sliding rod 502 to slide down along the inner cavity of the rotating rod 501 until the threaded rod 503 at the bottom of the sliding rod 502 is completely aligned with the first threaded hole 504 on the base plate 602.

[0025] In this embodiment, when installing the spring frame 601, the operator first moves both sets of mounting rings 603 on the spring frame 601 to the inner arc of the corresponding support frame 705. Then, by turning the handle 704, the bottom screw 701 is screwed into the second threaded hole 708. At this time, driven by the rotating ring 703, the connecting rod 702 rotates, thereby causing the limiting block 706 to slide inside the limiting groove 707. This allows the support frame 705 to press against the spring frame 601, thereby moving the mounting rings 603 to the inner side of the support hole 605. Then, the operator connects the mounting rings 603 to the support hole 605 with bolts 604, thus quickly installing the spring frame 601. The operator rotates the rotating rod 501 to keep it vertical, then pulls the sliding rod 502 to align the threaded rod 503 with the first threaded hole 504. The operator then screws the threaded rod 503 into the first threaded hole 504, thus fixing the position of the sliding rod 502. During the operation of the spring frame 601, this limits the movement of the leaf springs within the spring frame 601, effectively preventing the leaf springs from wobbling and ensuring stable operation of the spring frame 601. By installing the steel beam 400 inside the spring frame 601, the spring frame 601 can operate quickly and reduce vibration when the semi-trailer is traveling on rough roads, thus ensuring stable semi-trailer operation.
