A connecting rod 6 is installed on the connecting seat 3, and one end of the connecting rod 6 is used for fixing and connecting the foundation 1 by bolts. An adjustment mechanism 7 is installed at one end of the connecting seat 3, and the adjustment mechanism 7 is used to adjust the position of the connecting rod 6. A limiting mechanism 8 is installed on the bridge plate 4, and the limiting mechanism 8 is used to limit the guardrail 5. The bottom surface of the bridge plate 4 is provided with anti-slip grooves to enhance the friction between the bridge plate 4 and the connecting seat 3 and improve the stability of the trestle. A reinforcing rib 10 is provided at the bottom of the support column 2 to increase the connection strength between the support column 2 and the foundation 1 and improve the bearing capacity of the trestle.

[0031] See also Figure 2-4 The adjusting mechanism 7 comprises: a threaded rod 71, a threaded rod 71 is installed inside the connecting seat 3, threaded sliders 72 are symmetrically threaded at both ends of the threaded rod 71, the middle part of the threaded slider 72 is rotatably connected to the connecting rod 6, an extension rod 73 is slidably connected inside the connecting rod 6, threaded holes are equidistantly provided on one side of the extension rod 73, threaded holes are also provided on one side of the connecting rod 6, and the two corresponding threaded holes are fixedly connected by bolts 74, an L-shaped bracket 75 is fixedly connected to one side of the connecting seat 3, one end of the threaded rod 71 extends out of the L-shaped bracket 75, and a threaded groove is provided on one end of the threaded rod 71 extending out of the connecting seat 3, and one end of the threaded rod 71 is located on both sides of the L-shaped bracket 75 and is threadedly connected to fastening nuts 76.

[0032] It should be noted that the core component of the adjustment mechanism 7 is the threaded rod 71, and its design fully considers the flexibility and accuracy of the adjustment. Through the symmetrical thread design at both ends, the two threaded sliders 72 can move independently and synchronously on the threaded rod 71. This design not only realizes the dual adjustment of the position and direction of the connecting rod 6, but also ensures the stability and reliability of the adjustment process. The threaded rod 71 is a bidirectional threaded rod.

[0033] See also Figure 5-6The limiting mechanism 8 includes: a cylindrical clamping block 82, the guardrail 5 is designed in an I-shape and is slidably connected to the bridge plate 4, springs 81 are symmetrically fixedly connected on both sides of the guardrail 5 on the bridge plate 4, and the ends of the two springs 81 are fixedly connected to the cylindrical clamping blocks 82, and the cylindrical clamping block 82 is slidably connected to the bridge plate 4. A clamping groove 83 is opened on one side of the guardrail 5, and the cylindrical clamping block 82 is clamped with the clamping groove 83. One side of the cylindrical clamping block 82 is fixedly connected to an L-shaped push rod 9.

[0034] It should be noted that the guardrail 5 adopts an I-shaped design, which not only makes the guardrail 5 structure stable, but also can be slidably connected with the bridge plate 4. This sliding connection mode allows the guardrail 5 to easily slide to a predetermined position during installation and removal, thereby improving installation efficiency.

[0035] The working principle of the new assembled steel structure trestle provided by the utility model is as follows:

[0036] The main structure of the trestle includes a foundation 1, a support column 2, a connecting seat 3, a bridge deck 4 and a guardrail 5; among them, the design of the guardrail 5 is particularly unique. It adopts an I-shaped structure and is slidably connected with the bridge deck 4; this design not only ensures the stability of the guardrail 5, but also makes its installation and disassembly extremely convenient;

[0037] During the installation of the guardrail 5, the key component is the limiting mechanism 8; the limiting mechanism 8 is composed of a spring 81 and a cylindrical clamping block 82; when the guardrail 5 slides to the predetermined position of the bridge board 4, the spring 81 is compressed, pushing the cylindrical clamping block 82 to move toward the guardrail 5; at this time, the cylindrical clamping block 82 will accurately dock with the clamping groove 83 on the side of the guardrail 5 to form a clamping state, thereby firmly fixing the guardrail 5 on the bridge board 4;

[0038] This clamping design not only ensures the stability of the guardrail 5, but also makes it extremely easy to disassemble; when the guardrail 5 needs to be disassembled, it is only necessary to push the cylindrical clamping block 82 through the L-shaped push rod 9 to disengage it from the clamping slot 83, and then gently slide the guardrail 5 to achieve quick disassembly;

[0039] Due to terrain differences and installation errors, the connection base 3 and the foundation 1 may not be directly connected to each other in an ideal manner; in this case, the adjustment mechanism 7 plays a vital role.

[0040] The core component of the adjustment mechanism 7 is the threaded rod 71, which is designed as a bidirectional thread, so that the threaded sliders 72 at both ends can move independently; when the threaded rod 71 rotates, the threaded slider 72 will move accordingly, and adjust the position and direction of the connecting rod 6 through the rotation connection with the connecting rod 6; in this way, even if there is a slight installation deviation, the adjustment mechanism 7 can be accurately adjusted to ensure that one end of the connecting rod 6 can be accurately fixedly connected to the foundation 1 by bolts;

[0041] In addition to the direct adjustment of the connecting rod 6, the adjustment mechanism 7 also includes an extension rod 73; the function of the extension rod 73 is also to further adjust the connection seat 3 and the foundation 1. The extension rod 73 can slide to a suitable position and be fixedly connected to the connecting rod 6 by a bolt 74; in this way, through the coordinated use of the connecting rod 6 and the extension rod 73, a more precise and flexible adjustment of the trestle structure can be achieved.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
