Description

Technical Field

[0001] This utility model relates to the field of utility pole testing technology, and in particular to a testing device for the strength of concrete utility poles. Background Technology

[0002] After the concrete utility poles are manufactured, a rebound hammer in the testing device is pressed onto the surface of a sampled pole. The rebound value displayed by the rebound hammer is the strength test data of the utility pole. The operators compare the sampled test data with the test data of standard utility poles to obtain the strength test results of the utility poles, thereby ensuring the quality of the concrete utility poles produced.

[0003] Among them, a search revealed Chinese patent CN210037416U, which discloses a testing device for the strength of utility poles. In the application of the above patent's technical solution, the threaded rods controlling the rebound spring and the clamping plate are not located in the same place, which makes it inconvenient for operators to operate. Therefore, in order to better facilitate the use of the testing device, promote technological progress in the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the structure of the testing device in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing testing devices are inconvenient for operators to use, and to propose a testing device for the strength of concrete utility poles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for testing the strength of concrete utility poles includes a support assembly, a testing assembly, a sliding assembly, a clamping assembly, and a transmission assembly. The support assembly includes a top plate, with side plates fixedly connected to both ends of the bottom of the top plate. The testing assembly includes a rebound hammer. The sliding assembly includes a bidirectional threaded rod, which is rotatably mounted between the two side plates via interlocking bearings. Sliding plates are threaded to both ends of the bidirectional threaded rod. Two guide rods are fixedly connected between the two side plates, and the sliding plates slide between the two guide rods. The clamping assembly is located at the bottom of the sliding plates. The transmission assembly includes a connecting frame, which is fixed to the bottom of the top plate by bolts. A worm gear is rotatably mounted between the inner walls of the top and bottom ends of the connecting frame via interlocking bearings. The top end of the worm gear passes through the top plate. A worm wheel is keyed to the outer wall of the bidirectional threaded rod, and the worm wheel meshes with the worm gear.

[0007] Furthermore, a support frame is fixedly connected to the bottom of the side plate, two ground wheels are fixedly connected to the bottom of the support frame, and two support rods are fixedly connected between the two support frames.

[0008] Furthermore, the detection assembly includes a lead screw, which is rotatably mounted on the top plate via an interlocking bearing. A threaded cylinder is threadedly connected to the outer wall of the lead screw, and the rebound spring is fixed to the bottom end of the threaded cylinder by bolts.

[0009] Furthermore, two vertical rods are fixedly connected to the bottom of the top plate, and the bottom ends of the two vertical rods are fixedly connected to the same fixed plate, through which the threaded cylinder passes.

[0010] Furthermore, a sliding plate is fixedly connected to one side of the outer wall of the threaded cylinder, and the sliding plate slides between the two vertical rods.

[0011] Furthermore, the clamping assembly includes two clamping frames, which are fixed to the bottom end of the sliding plate by bolts, and anti-slip pads are adhered to the inner side of the clamping frames.

[0012] Furthermore, the top of the clamping frame is fixedly connected to two fixing ribs, one side of which is fixedly connected to one side of the sliding plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting the lead screw of the rebound spring and the worm gear of the clamping plate on the same top plate, it is convenient and quick for operators to operate.

[0015] 2. By turning the worm gear, the double-threaded rod rotates under the action of meshing with the worm wheel, which causes the sliding plate to move along the guide rod, thereby driving the two clamping frames to converge in the middle, thus clamping the concrete utility pole for subsequent inspection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A device for testing the strength of concrete utility poles includes a support assembly 1, a testing assembly 2, a sliding assembly 3, a clamping assembly 4, and a transmission assembly 5. The support assembly 1 includes a top plate 101, and side plates 102 are welded to both ends of the bottom of the top plate 101. Both the top plate 101 and the side plates 102 are made of high-strength steel.

[0025] The detection component 2 includes a rebound spring 205, and the sliding component 3 includes a bidirectional threaded rod 302. The threads at both ends of the bidirectional threaded rod 302 have opposite directions. The bidirectional threaded rod 302 is rotatably mounted between two side plates 102 via interlocking bearings. Both ends of the bidirectional threaded rod 302 are threadedly connected to sliding plates 303. Two guide rods 301 are welded between the two side plates 102 to ensure that the sliding plate 303 moves smoothly only in the horizontal direction, avoiding misalignment due to offset of the sliding plate 303. The sliding plate 303 slides between the two guide rods 301. The clamping component 4 is set on the sliding plate 302. At the bottom of the moving plate 303, the transmission assembly 5 includes a connecting frame 501, which is fixed to the bottom of the top plate 101 by bolts. A worm 503 is rotatably mounted between the inner wall of the top end and the inner wall of the bottom end of the connecting frame 501 through an embedded bearing. The top end of the worm 503 passes through the top plate 101. A worm wheel 502 is keyed to the outer wall of the bidirectional threaded rod 302. The worm wheel 502 meshes with the worm 503. The lead angle of the worm 503 is less than or equal to the equivalent friction angle. At this time, the worm wheel 502 cannot drive the worm 503 to rotate in the opposite direction by external force, that is, the transmission is irreversible, thereby achieving the purpose of locking.

[0026] Tightening the worm 503 causes the bidirectional threaded rod 302 to rotate under the meshing action of the worm 503 and the worm wheel 502, thereby causing the sliding plate 303 to move along the guide rod 301, which in turn causes the two sets of clamping components 4 to converge towards the middle, thus clamping the concrete utility pole.

[0027] A support frame 103 is welded to the bottom of the side plate 102. Two ground wheels 104 are fixed to the bottom of the support frame 103 by bolts, which facilitates the overall movement of the device. The ground wheels 104 are equipped with a braking function. Two support rods 105 are welded between the two support frames 103 to form a transverse reinforcement structure, which can enhance the lateral bending resistance of the support frame 103.

[0028] The testing component 2 includes a lead screw 202 with a trapezoidal thread. The lead screw 202 is rotatably mounted on the top plate 101 via an interlocking bearing. A threaded cylinder 204 is threadedly connected to the outer wall of the lead screw 202. A rebound hammer 205 is fixed to the bottom end of the threaded cylinder 204 by bolts. Tightening the lead screw 202 causes the threaded cylinder 204 to move downward along the lead screw 202, thereby driving the rebound hammer 205 to move downward and make close contact with the surface of the utility pole. The strength of the concrete utility pole is then tested by the rebound hammer 205.

[0029] Two vertical rods 201 are welded to the bottom of the top plate 101. The bottom ends of the two vertical rods 201 are welded to the same fixing plate 206. The threaded cylinder 204 passes through the fixing plate 206. A sliding plate 203 is fixed to one side of the outer wall of the threaded cylinder 204 by bolts. The sliding plate 203 slides between the two vertical rods 201. The sliding plate 203 can slide vertically along the vertical rods 201, which restricts the rotation of the threaded cylinder 204 and ensures that the threaded cylinder 204 moves only vertically and smoothly, so as to avoid the rebound hammer 205 from deviating during the movement, which would cause the detection point to be misaligned.

[0030] The clamping assembly 4 includes two clamping frames 401, which are fixed to the bottom of the sliding plate 303 by bolts. An anti-slip pad 402 is bonded to the inner side of the clamping frame 401. The anti-slip pad 402 is made of rubber material with a high coefficient of friction, such as nitrile rubber, and has anti-slip texture on its surface, which can increase the friction with the surface of the utility pole and prevent the utility pole from sliding during the inspection process.

[0031] Two fixing ribs 403 are welded to the top of the clamping frame 401. One side of the fixing rib 403 is fixedly connected to one side of the sliding plate 303, which can enhance the connection strength between the clamping frame 401 and the sliding plate 303 and prevent the clamping frame 401 from deforming due to excessive clamping force.

[0032] The working principle of this embodiment is as follows: When in use, firstly, push the support component 1 to make the ground wheel 104 roll on the ground, thereby moving the detection component 2 to the detection location. Then, turn the worm 503. Under the action of the worm 503 meshing with the worm wheel 502, drive the bidirectional threaded rod 302 to rotate, thereby causing the sliding plate 303 to move along the guide rod 301, which in turn drives the two clamping frames 401 to converge towards the middle, thereby clamping the concrete utility pole.

[0033] Then, the screw 202 is turned so that the threaded cylinder 204 moves downward along the screw 202. At the same time, the slide plate 203 moves downward along the vertical rod 201, thus ensuring that the threaded cylinder 204 moves downward smoothly, thereby driving the rebound hammer 205 downward. When the detection head of the rebound hammer 205 is perpendicular to and in close contact with the surface of the utility pole, the screw 202 is stopped, and the trigger button of the rebound hammer 205 is pressed. The impact hammer inside the rebound hammer 205 pops out and hits the surface of the utility pole. After the impact hammer rebounds, the pointer of the rebound hammer 205 will display the corresponding rebound value. The higher the rebound value, the higher the concrete strength. Finally, the staff records the rebound value and compares the data to determine the strength of the concrete utility pole, thus completing the test.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
