Description

Technical Field

[0001] This utility model relates to a plastic pipe diameter detection device, specifically a plastic pipe diameter detection device for road and bridge engineering, belonging to the technical field of road and bridge engineering testing equipment. Background Technology

[0002] In the construction and acceptance phases of road and bridge engineering, the application of plastic pipes spans core scenarios such as drainage systems, cable laying, and rainwater collection. The diameter deviation of plastic pipes must be controlled within a certain range. If the diameter exceeds the standard, it may cause a series of engineering hazards: for example, if the diameter of the drainage pipe is too small, it will lead to poor drainage of water accumulation on the road during the rainy season; if the diameter deviation of the communication protection pipe is too large, it will cause difficulties in cable laying; and even cause the pipe to break due to uneven stress during later use. Therefore, the diameter of plastic pipes must be accurately tested during the engineering acceptance phase to ensure that they meet the design and specification requirements.

[0003] However, plastic pipes are usually inspected using vernier calipers. Vernier caliper inspection requires bringing the calipers close to the pipe. When inspecting pipes that are tall, ladders or other tools are often needed to elevate the operator, which is quite cumbersome. In addition, multiple inspection points are often required for a single pipe, so the ladder needs to be moved frequently, which is quite exhausting. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the diameter of plastic pipes used in road and bridge construction in order to solve the above problems. This device can conveniently detect the diameter of pipes at high altitudes, improve the convenience of pipe detection at high altitudes, and can detect pipes from multiple angles, thus obtaining more accurate detection results.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a diameter detection device for plastic pipes used in road and bridge construction, comprising a long rod, a connecting shaft rotatably connected to the long rod, a measuring structure on the connecting shaft, an adjusting structure on the long rod, the adjusting structure comprising a guide seat and a sliding rod, two guide seats fixedly connected to the long rod, the same sliding rod slidably connected to the two guide seats, a connecting rod fixedly connected to one end of the sliding rod, a rack fixedly connected to the connecting rod, a gear fixedly connected to the connecting shaft, the rack meshing with the gear, and a limiting structure on one of the guide seats.

[0006] Preferably, the connecting rod has a cross-section in the shape of an "U", and a handle is fixedly connected to the long rod.

[0007] Preferably, the measuring structure includes a connecting block and a sleeve. The connecting block is fixedly connected to the connecting shaft, and a sleeve is fixedly connected to one end of the connecting block. A sliding tube is slidably connected inside the sleeve. One clamping rod is fixedly connected to the sleeve, and another clamping rod is fixedly connected to the sliding tube.

[0008] Preferably, the slide tube has multiple graduated grooves on both sides, and the cross-section of one end of the clamping rod is trapezoidal.

[0009] Preferably, a threaded sleeve is fixedly connected to the sleeve, and a knob is threadedly connected to the threaded sleeve.

[0010] Preferably, the limiting structure includes guide posts and a pull plate, two guide posts are fixedly connected to one of the guide seats, the same pull plate is slidably connected to the two guide posts, the slide rod is provided with multiple slots, a locking block is fixedly connected to one side of the pull plate, and one end of the locking block engages with one of the slots.

[0011] Preferably, a spring is sleeved on the outside of the guide post, with one end of the spring abutting against the guide post and the other end of the spring abutting against the guide seat.

[0012] Preferably, the cross-section of one end of the card block is trapezoidal, and the cross-section of one end of the guide post is T-shaped.

[0013] The beneficial effects of this utility model are as follows: When inspecting plastic pipes at high locations, a long handheld pole can be used. Due to the considerable height of the pole, the measuring personnel can move the measuring structure to a higher position, thus enabling the inspection of pipes at high locations without the need for a ladder. This significantly improves the convenience of inspecting pipes at high locations. Furthermore, when inspecting different positions of the pipe, a sliding rod can be pushed. The sliding rod drives a connecting rod, which in turn drives a rack, which in turn drives a gear. The gear's rotation causes the connecting shaft to rotate, changing the orientation of the measuring structure. By changing the orientation of the measuring structure, the diameter of the pipe can be inspected at different locations, resulting in more comprehensive inspection data and improved inspection accuracy.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-6 As shown, a plastic pipe diameter detection device for road bridges includes a long rod 1, a connecting shaft 2 is rotatably connected to the long rod 1, a measuring structure 3 is provided on the connecting shaft 2, an adjusting structure 4 is provided on the long rod 1, the adjusting structure 4 includes a guide seat 401 and a slide bar 402, two guide seats 401 are fixedly connected to the long rod 1, the same slide bar 402 is slidably connected to the two guide seats 401, one end of the slide bar 402 is fixedly connected to a connecting rod 403, a rack 404 is fixedly connected to the connecting rod 403, a gear 405 is fixedly connected to the connecting shaft 2, the rack 404 and the gear 405 are meshed with each other, and a limiting structure 5 is provided on one of the guide seats 401.

[0018] As a technical optimization scheme of the present utility model, the cross-section of the connecting rod 403 is in a "C" - shaped structure, and a handle 406 is fixedly connected to the long rod 1, so that the slide bar 402 can be conveniently moved by holding the handle 406.

[0019] The measuring structure 3 includes a connecting block 301 and a sleeve 302. The connecting block 301 is fixedly connected to the connecting shaft 2. The sleeve 302 is fixedly connected to one end of the connecting block 301. A sliding tube 303 is slidably connected inside the sleeve 302. One clamping rod 304 is fixedly connected to the sleeve 302. Another clamping rod 304 is fixedly connected to the sliding tube 303. Therefore, the pipe diameter can be measured by inserting the pipe between the two clamping rods 304.

[0020] As a technical optimization of this utility model, multiple scale grooves 305 are provided on both sides of the slide tube 303. Therefore, the distance between the two clamping rods 304 can be known by pointing the edge of the sleeve 302 to different scale grooves 305. The cross-section of one end of the clamping rod 304 is trapezoidal, so it can play a role in guiding the movement when the pipe is inserted between the two clamping rods 304.

[0021] As a technical optimization of this utility model, a threaded sleeve 306 is fixedly connected to the sleeve 302, and a knob 307 is threadedly connected to the threaded sleeve 306. Therefore, the fixed position of the slide tube 303 is achieved by the contact between the end of the knob 307 and the slide tube 303.

[0022] As a technical optimization of this utility model, the limiting structure 5 includes guide posts 501 and pull plates 502. Two guide posts 501 are fixedly connected to one of the guide seats 401. The pull plates 502 can be guided by the two guide posts 501. The same pull plate 502 is slidably connected to the two guide posts 501. The slide rod 402 is provided with multiple slots 504. A locking block 503 is fixedly connected to one side of the pull plate 502. One end of the locking block 503 engages with one of the slots 504. Therefore, by locking the locking block 503 into the interior of different slots 504, the orientation of the two clamping rods 304 can be adjusted.

[0023] As a technical optimization of this utility model, a spring 505 is sleeved on the outside of the guide post 501. One end of the spring 505 abuts against the guide post 501, and the other end of the spring 505 abuts against the guide seat 401. Therefore, under the action of the spring 505, the locking block 503 can always be engaged with the locking groove 504.

[0024] As a technical optimization of this utility model, the cross-section of one end of the locking block 503 is trapezoidal, so it can play a role in guiding the movement when the locking block 503 and the locking groove 504 are engaged. The cross-section of one end of the guide post 501 is T-shaped, so it can limit the spring 505.

[0025] When in use, the utility model can adjust the positions of the two clamping rods 304 according to the required standard diameter of the pipeline to be detected. During the adjustment, the sliding pipe 303 can slide inside the sleeve 302. When the sliding pipe 303 moves, the distance between the two clamping rods 304 will change. By providing scale grooves 305 on both sides of the sliding pipe 303, and different dimensions can be marked on one side of the scale grooves 305 on both sides, so that the distance between the two clamping rods 304 can be known by the scale groove 305 corresponding to the edge of the sleeve 302 at a specified scale. When the distance between the two clamping rods 304 is adjusted to the standard diameter of the pipeline to be detected, the knob 307 can be rotated. When one end of the knob 307 is tightly pressed against one side of the sliding pipe 303, the sliding pipe 303 cannot slide on the sleeve 302, and at this time the distance between the two clamping rods 304 cannot change. Then, the long rod 1 can be held by hand to make the pipeline to be detected clamped between the two clamping rods 304. If the pipeline can just be clamped between the two clamping rods 304, it is qualified; otherwise, it is unqualified. During the detection, since the long rod 1 has a relatively long height, the measuring personnel can move the two clamping rods 304 to a relatively high height by holding the long rod 1 by hand, so that the detection of the high pipeline can be realized without the need to use a ladder, effectively improving the convenience of the high pipeline detection. At the same time, when it is necessary to detect different orientations of the pipeline, the pull plate 502 can be pulled. The movement of the pull plate 502 will cause the clamping block 503 to move away from one of the clamping slots 504, and the two springs 505 will contract simultaneously. When one end of the clamping block 503 is not engaged with one of the clamping slots 504, the sliding rod 402 can be pushed. The sliding rod 402 will drive the connecting rod 403 to move. The movement of the connecting rod 403 will drive the rack 404 to move. The movement of the rack 404 will drive the gear 405 to rotate. The rotation of the gear 405 will cause the connecting shaft 2 to rotate. The rotation of the connecting shaft 2 will change the orientation of the two clamping rods 304. By inserting the clamping block 503 into different clamping slots 504, the clamping rods 304 can be oriented in different directions, so that the diameters of different directions of the pipeline can be detected, and more comprehensive detection data can be obtained, which is convenient for improving the accuracy of the detection.
