Description

Technical Field

[0001] This utility model relates to the field of bridge pile testing technology, specifically to a strength testing device for bridge piles. Background Technology

[0002] Bridge piles are infrastructure used in bridge construction to support beam structures or piers. Their main function is to provide stable foundation support for bridges, ensuring that bridges have stable support points under various geological conditions, thereby guaranteeing the safety and smooth flow of traffic.

[0003] To improve the efficiency of bridge installation, people usually use steel bars and concrete to prefabricate bridge piles. To ensure the strength of the bridge piles, their strength usually needs to be tested after production. This requires the use of strength testing equipment. However, existing strength testing equipment usually tests from the outside of the bridge, and the testing equipment is relatively large, making it difficult to test the strength from the inside of the bridge, thus affecting the test results. Utility Model Content

[0004] In view of the problems existing in the strength testing equipment for bridge piles, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a strength testing device for bridge piles, which solves the problem that existing strength testing devices usually test from the outside of the bridge and are relatively large, making it difficult to test the strength from the inside of the bridge, thus affecting the test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A strength testing device for bridge piles includes a bridge pile body. A fixing block is disposed inside the bridge pile body. Slide grooves are formed on both sides of the fixing block. Fixing mechanisms are disposed inside each of the slide grooves. The fixing block is fixedly connected to the interior of the bridge pile body via the fixing mechanisms. A cavity is formed between the two slide grooves. An adjustment mechanism is disposed inside the cavity. Both fixing mechanisms are matched with the adjustment mechanism. A limit mechanism is disposed on the upper surface of the fixing block. The adjustment mechanism is matched with the fixing mechanism. Two cylinders are symmetrically fixedly connected to the upper surface of the fixing block. A top plate is fixedly connected to the output ends of the two cylinders. An installation groove is formed on the upper surface of the top plate. A pressure sensor is fixedly connected inside the installation groove.

[0008] Preferably, the fixing mechanism includes two lead screws, two sleeves, two fixing plates, and two first bevel gears. The two lead screws are rotatably connected to the interior of the corresponding slide grooves. The two sleeves are threaded onto the rod walls of the corresponding lead screws. One end of each of the two lead screws passes through one side of the corresponding slide groove and extends into the interior of the cavity. The two first bevel gears are respectively sleeved onto the rod walls of one end of the corresponding lead screws. The two fixing plates are respectively fixedly connected to one end of the sleeves.

[0009] Preferably, the adjusting mechanism includes a rotating rod, a second bevel gear, and a handle. The rotating rod is rotatably connected to the interior of the cavity, and the lower end of the rotating rod penetrates the lower surface of the cavity and is fixedly connected to the handle. The second bevel gear is fixedly sleeved on the rod wall of the rotating rod and meshes with two first bevel gears.

[0010] Preferably, the limiting mechanism includes a fixed frame, a rod, a baffle, a spring, a pull ring, and a circular plate. The fixed frame is fixedly connected to the upper surface of the fixed block. A through hole is provided on the upper surface of the fixed frame. The rod is slidably disposed inside the through hole.

[0011] Preferably, the upper surface of the circular plate is provided with a plurality of slots, and the lower end of each of the inserts penetrates the upper surface of the fixing block and matches each slot.

[0012] Preferably, the inner walls of the two slides are symmetrically provided with limiting grooves, and the interior of the two limiting grooves is slidably provided with limiting blocks, each of the limiting blocks being fixedly connected to the outer surface of the corresponding sleeve.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model uses two cylinders to activate the top plate, which then presses against the inner wall of the bridge pile body. The pressure applied by the top plate to the bridge pile body can be detected by a pressure sensor, thereby testing the strength of the bridge pile body.

[0015] 2. In this utility model, by turning the handle, the rotating rod is rotated, which in turn causes the second bevel gear to rotate.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a strength testing device for bridge piles.

[0024] This utility model provides, for example Figure 1-3 The strength testing device for bridge piles shown includes a bridge pile body 1. A fixing block 2 is provided inside the bridge pile body 1. Slide grooves are provided on both sides of the fixing block 2. Fixing mechanisms are provided inside the two slide grooves. The fixing block 2 is fixedly connected to the inside of the bridge pile body 1 through the fixing mechanisms. A cavity is provided between the two slide grooves. An adjustment mechanism is provided inside the cavity. The two fixing mechanisms are matched with the adjustment mechanisms. A limit mechanism is provided on the upper surface of the fixing block 2. The adjustment mechanism is matched with the fixing mechanism. Two cylinders 3 are symmetrically fixedly connected to the upper surface of the fixing block 2. The output ends of the two cylinders 3 are fixedly connected to a top plate 4. An installation groove is provided on the upper surface of the top plate 4. A pressure sensor 5 is fixedly connected inside the installation groove.

[0025] The fixing block 2 is placed inside the bridge pile body 1, and then the fixing mechanism is used to fix the fixing block 2. Then, the two cylinders 3 are activated, and the top plate 4 is pressed against the inner wall of the bridge pile body 1. The pressure sensor 5 can then detect the pressure applied by the top plate 4 to the bridge pile body 1, thereby detecting the strength of the bridge pile body.

[0026] To fix block 2, such as Figure 1 As shown, the fixing mechanism includes two lead screws 6, two sleeves 7, two fixing plates 8, and two first bevel gears 9. The two lead screws 6 are rotatably connected to the interior of the corresponding slide grooves. The two sleeves 7 are threaded onto the rod walls of the corresponding lead screws 6. One end of each lead screw 6 passes through one side of the corresponding slide groove and extends into the interior of the cavity. The two first bevel gears 9 are respectively sleeved onto the rod walls of one end of the corresponding lead screw 6. The two fixing plates 8 are respectively fixedly connected to one end of the sleeves 7. The adjusting mechanism includes a rotating rod 10, a second bevel gear 11, and a handle 12. The rotating rod 10 is rotatably connected to the interior of the cavity. The lower end of the rotating rod 10 passes through the lower surface of the cavity and is fixedly connected to the handle 12. The second bevel gear 11 is fixedly sleeved onto the rod wall of the rotating rod 10 and meshes with the two first bevel gears 9.

[0027] Turning handle 12 causes the rotating rod 10 to rotate, which in turn causes the second bevel gear 11 to rotate. This, in turn, drives the two first bevel gears 9 to rotate, which in turn causes the two lead screws 6 to rotate. Subsequently, the two sleeves 7 drive the corresponding fixing plates 8 to move, so that the two fixing plates 8 press against the inner wall of the bridge pile body 1, thereby fixing the fixing block 2.

[0028] To prevent the rotating rod 10 from rotating during use, such as Figure 1-3 As shown, the limiting mechanism includes a fixed frame 13, a rod 14, a baffle 15, a spring 16, a pull ring 17, and a circular plate 18. The fixed frame 13 is fixedly connected to the upper surface of the fixed block 2. A through hole is provided on the upper surface of the fixed frame 13. The rod 14 is slidably disposed inside the through hole. The baffle 15 is fixedly sleeved on the rod wall of the rod 14. The spring 16 is slidably sleeved on the rod wall of the rod 14. The circular plate 18 is fixedly connected to the upper end of the rotating rod 10. Multiple slots are provided around the upper surface of the circular plate 18. The lower end of each rod 14 penetrates the upper surface of the fixed block 2 and matches each slot.

[0029] Pulling the pull ring 17 moves the insertion rod 14 out of the slot, which then allows the circular plate 18 to rotate, i.e., the rotating rod 10 to rotate. After the rotating rod 10 rotates, the pull ring 17 is released, and the spring force of the spring 16 pushes the baffle 15 to move, thereby moving the insertion rod 14 into the corresponding slot, thus fixing the circular plate 18 and the rotating rod 10.

[0030] To prevent sleeve 7 from rotating, such as Figure 1As shown, the inner walls of the two slides are symmetrically provided with limiting grooves, and the interior of the two limiting grooves is provided with limiting blocks 19, each limiting block 19 being fixedly connected to the outer surface of the corresponding sleeve 7.

[0031] Each limit block 19 can be used to limit the movement, thereby preventing the sleeve 7 from rotating with the corresponding lead screw 6.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
