Description

Technical Field

[0001] This utility model relates to the field of power pipe testing, specifically a power pipe impact resistance testing device. Background Technology

[0002] Electrical conduits are commonly used plastic pipes, often pre-embedded in walls during construction to facilitate the passage of electrical wires. These conduits are subjected to compression during concrete setting, and the conduits also need to withstand the impact of vibrators used during concrete pouring to prevent breakage. Furthermore, the cost of replacing pre-embedded electrical conduits is relatively high. Therefore, impact resistance testing of electrical conduits is an important aspect of construction. Existing impact resistance testing equipment for electrical conduits includes [list of equipment]. CN222579858U The method involves setting a second limit block on the wire rope to limit the lifting height of the lifting frame, and disconnecting the power supply to the electromagnet through a spring switch assembly. This causes the lowering frame to rise to a predetermined height and then be released, thus falling and impacting the power pipe under test to simulate an impact. However, in actual use, when the lowering frame falls under the action of gravity, it needs to fall along the guide tube. There is friction between the lowering frame and the guide tube, which affects the free fall of the lowering frame and thus affects the test results. Therefore, we propose an impact resistance testing device for power pipes. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this invention, when the electromagnetic block is de-energized, the impact block detaches from the electromagnetic block and falls onto the power pipe, thus completing the impact detection. When the impact block falls, it is constrained by the impact pipe to ensure that the impact block will hit the power pipe, and there will be no large friction between the impact block and the impact pipe, reducing the impact on the fall of the impact block. In addition to ensuring that the impact block hits the power pipe, the hydraulic cylinder is activated to drive the lifting frame to move down. The movement of the lifting frame will also drive the impact pipe to move down, so that the arc groove at the bottom of the impact pipe will tightly fit the outside of the power pipe, thereby fixing the power pipe. The impact block, together with four sets of placement blocks, can stably clamp the power pipe. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 - Figure 3This utility model discloses an impact resistance testing device for power pipes, comprising a support 1, a hydraulic cylinder 2 fixedly installed at the top of the support 1, the telescopic end of the hydraulic cylinder 2 slidingly penetrating the inner side of the support 1 and fixedly connected to a lifting frame 3, an impact component 4 mounted on the lifting frame 3, and an adjustment component 5 mounted on the lifting frame 3, the impact force of the impact component 4 on the power pipe being adjusted by the adjustment component 5.

[0018] The impact assembly 4 includes an impact tube 401, a slider 402 slidably connected inside the impact tube 401, an electromagnet 403 fixedly installed inside the slider 402, and an impact block 404 adsorbed and connected to the bottom of the electromagnet 403. When the electromagnet 403 is in use, it needs to be connected to a suitable external power supply with its dedicated controller and controlled by the controller. When the electromagnet 403 is energized and generates magnetic force, it can firmly attract the impact block 404. When the electromagnet 403 is de-energized, the impact block 404 detaches from the electromagnet 403 and falls to hit the power tube. When the impact block 404 falls, under the restriction of the impact tube 401, it is ensured that the impact block 404 will hit the power tube. There will be no large friction between the impact block 404 and the impact tube 401, reducing the impact on the fall of the impact block 404.

[0019] The impact tube 401 is fixedly connected to the lifting frame 3, and the bottom of the impact tube 401 is set to be arc-shaped. When in use, the arc-shaped groove at the bottom of the impact tube 401 will tightly fit the outside of the power pipe, thereby fixing the power pipe.

[0020] The adjustment assembly 5 includes two sets of fixed seats 501, both of which are fixedly installed on the outer wall of the impact tube 401. Both sets of fixed seats 501 are rotatably connected to screws 502 via bearings. The screws 502 are threadedly connected to the inner side of the slider 402. Two sets of guide rods 503 are fixedly installed between the two sets of fixed seats 501. Both sets of guide rods 503 slide through the inner side of the slider 402. A servo motor 504 is fixedly installed at the top of one set of fixed seats 501. The drive end of the servo motor 504 passes through the inner side of the fixed seat 501 and is fixedly connected to the screws 502. In use, starting the servo motor 504 will drive the screws 502 to rotate. The rotation of the screws 502 will drive the slider 402 to move up and down along the guide rods 503, thereby adjusting the distance between the impact block 404 and the power tube. When using the servo motor 504, it needs to be connected to a suitable external power supply with its dedicated controller and controlled by the controller. The servo motor 504 is a servo motor with a uniform self-locking mechanism.

[0021] Two sets of guide rods 6 are fixedly installed at the top of the lifting frame 3. Both sets of guide rods 6 slide through the inner side of the bracket 1. The two sets of guide rods 6 provide guidance for the hydraulic cylinder 2 to drive the lifting frame 3 to move up and down. When the hydraulic cylinder 2 is used, it needs to be used with a hydraulic pump, hydraulic pipeline, etc., and the hydraulic pump and its controller are connected to a suitable external power supply.

[0022] The bracket 1 is fixedly installed on the top of the testing platform 7, and multiple sets of support legs 8 are fixedly installed on the bottom of the testing platform 7, so that the device installation structure is stable.

[0023] Four sets of placement blocks 9 are fixedly installed on the top of the testing platform 7. Each placement block 9 has an arc-shaped groove. In use, the power pipe can be supported by the placement blocks 9.

[0024] The working principle of this utility model is as follows: In use, the power tube is placed in the arc-shaped groove of the placement block 9. The hydraulic cylinder 2 is activated to drive the lifting frame 3 to move down. The movement of the lifting frame 3 will drive the impact tube 401 to move down, so that the arc-shaped groove at the bottom of the impact tube 401 will tightly fit the outside of the power tube, thereby fixing the power tube. Then, the servo motor 504 is activated to drive the screw 502 to rotate. The rotation of the screw 502 will drive the slider 402 to move up and down along the guide rod 503, thereby adjusting the distance between the impact block 404 and the power tube. Then, the electromagnetic block 403 is de-energized, and the impact block 404 falls off the electromagnetic block 403 and hits the power tube, thereby completing the impact detection. When the impact block 404 falls, under the restriction of the impact tube 401, it is ensured that the impact block 404 will hit the power tube. There will be no large friction between the impact block 404 and the impact tube 401, reducing the impact on the fall of the impact block 404.

[0025] After the testing is completed, the servo motor 504 is restarted to drive the slider 402 to move down. The slider 402 moves down and drives the electromagnetic block 403 to move down, so that the electromagnetic block 403 contacts the impact block 404. When the electromagnetic block 403 is energized again, the electromagnetic block 403 will attract the impact block 404 again.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions.
