Description

Technical Field

[0001] This utility model relates to the field of steel-concrete composite arch bridges, and in particular to a combined bearing capacity testing platform. Background Technology

[0002] A steel-concrete composite arch bridge is a type of arch bridge that combines steel pipes and concrete. The safety of a steel-concrete composite arch bridge is paramount. During construction, factors such as the quality of concrete pouring and the degree of coordination between the steel pipes and concrete affect the actual load-bearing capacity of the structure. A load-bearing capacity testing platform can accurately detect whether the structure meets the design requirements for load-bearing capacity. Different testing equipment has its own advantages; combining these devices on a single platform allows for multi-faceted testing of the load-bearing capacity of a steel-concrete composite arch bridge, providing complementary and verifiable results.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: the existing load-bearing capacity testing platform generally includes a testing mechanism, a support mechanism, a fixing bolt and other structures. Most of the existing testing mechanisms are integrated with the support mechanism. When multi-angle testing is required, the entire equipment must be replaced for testing, which is troublesome and time-consuming. At the same time, most of the existing support mechanisms are fixed, which occupy too much space after use, thus wasting space.

[0004] Therefore, those skilled in the art have provided a combined load-bearing capacity testing platform to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combined load-bearing capacity testing platform. The support mechanism reduces the space occupied, while the fixing mechanism makes the testing results more comprehensive and accurate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined load-bearing capacity testing platform, comprising a support mechanism and a fixing mechanism. The support mechanism includes a fixed slide plate and four fixing bolts. A sliding plate is slidably connected to the inner wall of the fixed slide plate. A first shaft is rotatably connected to the inner wall of the fixed slide plate on the side away from the sliding plate. A first plate is fixedly connected to both the front and rear ends of the first shaft. A second shaft is rotatably connected to the inner wall of the sliding plate on the side away from the fixed slide plate. A second plate is fixedly connected to both the front and rear ends of the second shaft.

[0007] The fixing mechanism includes a double-ended screw, a bearing block is rotatably connected to the middle of the outer wall of the double-ended screw, a fixing plate is threadedly connected to the outer wall of the double-ended screw away from the bearing block, a movable plate is slidably connected to the inner wall of the two fixing plates, a card plate is fixedly connected to the top of the movable plate.

[0008] Furthermore, the bottoms of the two card plates are movably connected to the tops of the two fixed plates, and a pull block is fixedly connected to the tops of the two card plates.

[0009] Furthermore, multiple springs are fixedly connected to the bottom of the inner walls of both fixed plates, and the tops of the multiple springs are fixedly connected to the bottoms of the two movable plates.

[0010] Furthermore, the bottom of one of the two fixed plates is slidably connected to the top of the sliding plate, and the bottom of the other fixed plate is slidably connected to the top of the fixed slide plate.

[0011] Furthermore, the sliding plate and the inner wall of the top of the fixed sliding plate are both threadedly connected to four fixing bolts, and the outer walls of the second shaft and the first shaft are both movably connected to the bottom of the four fixing bolts.

[0012] Furthermore, the top side of the fixed slide plate is fixedly connected to the support block, the top of the support block is movably connected to the testing machine, and the outer walls of the testing machine are movably connected to the two fixed plates near the testing machine.

[0013] Furthermore, the two second plates, the two first plates, and the outer walls of the fixed slide plate and the sliding plate are all movably connected with fixing strips, and the multiple fixing strips are elastic bands.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a combined load-bearing capacity testing platform. Three fixing bars are removed, freeing the platform from restricting plate number one and plate number two. The sliding plate is then pulled to the left, and four fixing bolts are removed. After losing their fixation to axle number one and plate number two, plate number one and plate number two are rotated 90 degrees to make their bottoms parallel to the ground. The fixing bolts are then reset to re-fix axle number one and plate number two, preventing them from swaying left and right. When not in use, the entire platform can be folded for storage, reducing space occupation and improving space utilization.

[0016] 2. The combined load-bearing capacity testing platform proposed in this utility model allows for the following steps when changing the placement of different testing machines: Rotating the double-ended screw causes the two threaded fixing plates to move inwards to secure the testing machine; pulling the two pull blocks, clamping plates, moving plates, and springs upwards; then releasing the upward movement allows the two clamping plates to be pulled downwards by the springs to secure the testing machine. By changing different testing machines, the test data can be more comprehensive and accurate, ensuring the quality and speed of subsequent projects. Attached Figure Description

[0026] Specifically, remove the multiple fixing strips 2 to remove their restriction on plate 102 and plate 107. Pull the sliding plate 105 to the left along the inner wall of the fixed sliding plate 101. Then rotate the four fixing bolts 104 and remove them to remove their fixation on shaft 103 and shaft 106. Rotate plate 102 and plate 107 90 degrees so that their bottom edges contact the ground and remain parallel. Finally, rotate the multiple fixing bolts 104 in the opposite direction to re-fix shaft 103 and shaft 106 to prevent left and right swaying and maintain stability.

Pull blocks 405 are fixedly connected to the tops of the two card plates 406. Multiple springs 403 are fixedly connected to the bottom of the inner walls of each of the two fixed plates 402. The tops of the multiple springs 403 are fixedly connected to the bottoms of the two movable plates 407. The bottom of one of the fixed plates 402 is slidably connected to the top of the sliding plate 105. The bottom of the other fixed plate 402 is slidably connected to the top of the fixed slide plate 101. The sliding plate 105 is connected to the fixed slide plate 101. The top inner wall of 01 is threadedly connected to four fixing bolts 104. The outer walls of shaft 2 106 and shaft 1 103 are movably connected to the bottom of the four fixing bolts 104.

Rotate multiple fixing bolts 104 to move it upward and lose the fixation of the bottom first shaft 103 and second shaft 106. Rotate the first shaft 103 and second shaft 106 to drive the first plate 102 and second plate 107 to rotate 90 degrees so that their bottoms are parallel to the ground. Then rotate the multiple fixing bolts 104 in the opposite direction to re-fix the first shaft 103 and second shaft 106 to prevent it from shaking.

[0030] Next, when different testing machines 3 are placed on top of the support block 404, rotate the double-headed screw 401 to move the two fixing plates 402 connected by the outer wall threads inward to clamp and fix the testing machine 3. Pull the two pull blocks 405 upward to move the bottom clamping plate 406 and the moving plate 407 upward. The two moving plates 407 move upward to pull the multiple springs 403 at the bottom upward. When the two clamping plates 406 cover the top of the bottom testing machine 3, release your hand. Under the action of the multiple springs 403, the two clamping plates 406 will be pulled downward to fix the testing machine 3.
