Description

Technical Field

[0001] The utility model belongs to the technical field of trestles, and in particular relates to a water conservancy construction transportation trestles. Background Art

[0002] Water conservancy construction mainly refers to the construction of different types of hydraulic structures such as dams, dikes, sluice gates, and channels. During the construction process, foundation pits are easily formed, resulting in the inability to deliver construction materials to the construction site in a timely manner. To solve the above problem, the existing technology usually builds concrete bridges for transportation. The construction process is time-consuming and needs to be dismantled in the later stage of the project. It cannot be reused, which wastes resources.

[0003] A Chinese patent with publication number CN115341466A discloses a temporary plank bridge structure for a water conservancy project. The scheme includes a first main body and a second main body. One end of the first main body is fixedly connected to a fixed connection block, and one end of the second main body is provided with an installation groove for clamping with the fixed connection block. One end of the surface of the first main body is fixedly connected to a first limit block, and the other end of the surface of the second main body is fixedly connected to a second limit block. The above scheme utilizes the fixed connection block to be clamped in the installation groove to realize the splicing of the first main body and the second main body, which is convenient for the staff to disassemble and assemble the bridge structure.

[0004] In actual work, the ground after excavation usually has potholes and is uneven. During use of the above-mentioned solution, it is necessary to clamp the fixed connecting block in the installation groove. This step requires that the surfaces of the first main body and the second main body are located in the same plane, but because the lengths of the first limit block and the second limit block are fixed, part of the first limit block or the second limit block cannot contact the ground, resulting in poor stability of the above-mentioned solution when it is installed on the pothole-prone ground, and the applicable scenarios are relatively limited. Utility Model Content

[0005] The utility model aims to provide a water conservancy construction transport trestle to solve the problem that the above-mentioned solution has limited applicable scenarios.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water conservancy construction transport trestle comprises a support frame and a bridge deck, wherein the left and right sides of the bottom of the support frame are respectively provided with vertical rods, the bottoms of the vertical rods are slidably inserted with support rods, and a lifting mechanism is also arranged in the vertical rods for driving the support rods to move up and down, the support frames are arranged in plurality at intervals along the front and rear directions, and the bridge decks are arranged in plurality, each bridge deck is arranged between two adjacent support frames, and the front and rear ends of each bridge deck are respectively rotatably connected to the top of the corresponding support frame.

[0008] The principle and effect of this technical solution:

[0009] Make the two lifting mechanisms in the first support frame move the corresponding support rods to the appropriate positions respectively, fix the first support frame on the ground in a horizontal posture, and rotatably connect the front end of the first bridge panel with the top of the first support frame. According to the above steps, fix the next support frame on the ground, make the rear end of the first bridge panel and the front end of the next bridge panel with the top of the next support frame, and repeat the above operations to set the corresponding number of support frames and bridge panels according to the actual length on site.

[0010] Through the above arrangement, the support rods are slidably inserted into the bottom of the two vertical rods at the bottom of the support frame, and the length of the corresponding support rods extending out of the vertical rods is adjusted by the lifting mechanism to make the top of the support frame in a horizontal state, so that the device can stably set up the support frame on the bumpy ground, which solves the problem of the limited application scenarios of the above solution.

[0011] In the utility model, the lifting mechanism includes a screw and a rotating shaft. The screw is arranged in the vertical rod for vertical rotation. The top of the support rod is fitted on the bottom of the screw. The rotating shaft is inserted into the vertical rod for horizontal rotation. The top of the screw and the end of the rotating shaft extending into the vertical rod are respectively fixed with mutually meshing bevel gears.

[0012] The principle and effect of this technical solution:

[0013] When the rotating shaft is rotated, the two bevel gears fixed on the top of the screw and extending into one end of the vertical rod of the rotating shaft mesh with each other, thereby driving the screw to rotate. Since the vertical rod limits the rotation of the support rod, the support rod moves up and down with the rotation of the screw.

[0014] Through the above arrangement, the purpose of using the lifting mechanism to drive the support rod to move is achieved, so that the utility model can be stably erected on the pothole ground.

[0015] In the utility model, the front and rear ends of the bridge deck are respectively fixed with a first connecting ear and a second connecting ear, and the first connecting ear and the second connecting ear are staggered in the left and right directions. A connecting block is fixedly provided on the top of the support frame, and a round pin is slidably inserted at the right end of the connecting block. The first connecting ear and the second connecting ear are both provided with pin holes that cooperate with the round pin.

[0016] In the utility model, the support frame is provided with a slide groove in the horizontal direction below the connecting block, a slider is fixedly provided at the bottom of the round pin, the slider is slidably embedded in the slide groove, a tension spring is provided in the slide groove, and both ends of the tension spring are respectively connected to the slider and the right end wall of the slide groove.

[0017] In the utility model, a through groove is arranged at the bottom of the slide groove along its length direction, and a lever which slides through the through groove is fixedly arranged at the bottom of the slide block.

[0018] The principle and effect of this technical solution:

[0019] When installing the bridge deck, push the lever to move the slider to the left end of the slide slot, thereby driving the round pin to move to the left and stretching the tension spring until the round pin moves into the connecting block. Move the bridge deck to align the pin holes on the first connecting ear and the second connecting ear with the corresponding round pins. Release the lever, and the tension spring pulls the slider to reset, so that the round pin passes through the pin holes on the first connecting ear and the second connecting ear in turn.

[0020] The above arrangement can facilitate the workers to disassemble and assemble the bridge deck, and the tension spring can be used to prevent the round pin from falling out of the first connecting ear and the second connection, thereby improving the safety of the utility model during use.

[0021] In the utility model, a support plate is fixedly arranged at the bottom of the support rod in the horizontal direction, and through holes for inserting the drill rod are opened at the four corners of the top of the support plate. Through the above arrangement, the drill rod passes through the through hole on the support plate and is inserted into the ground, so that the support rod is fixed on the ground, and then the support frame is fixed on the pit ground.

[0022] The utility model further comprises an oblique support rod, which is X-shaped and arranged between the two vertical rods, and the left and right ends of the oblique support rod are respectively fixedly connected to the vertical rods by bolts. The above arrangement can further improve the stability of the utility model when in use. BRIEF DESCRIPTION OF THE DRAWINGS
