Description

Technical Field

[0001] This utility model relates to the field of building construction related equipment, and in particular to a pipe inversion construction device for building pipe wells. Background Technology

[0002] A pipe inversion construction device for building pipe shafts is a specialized piece of equipment used for inverting pipe installations within pipe shafts. It refers to a construction method where pipes are installed section by section from top to bottom within the pipe shaft. Using hoisting equipment, pipe sections are installed one by one from a higher position to a lower position. All welds are made in fixed positions. After each section is welded, it is lifted upwards to install the next section until the entire vertical pipe is installed. The aim is to improve construction efficiency, ensure construction safety, and reduce the impact on the surrounding environment.

[0003] Currently, existing pipe inversion construction equipment for building pipe wells is not adaptable enough and may not be able to fully adapt to pipes of different diameters. Especially when dealing with non-standard pipes, it is necessary to replace the equipment with one of the appropriate specifications according to the pipe and then repeat the hoisting operation. This requires frequent replacement or adjustment of equipment parts, which increases construction time and cost. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a construction device for reversing pipe installation in building pipe wells.

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

[0006] The pipe inversion construction device for building pipe wells includes a frame, a dual-axis motor mounted on the frame, and support mechanisms respectively mounted on the two output ends of the dual-axis motor. Each of the two support mechanisms includes a bidirectional screw mounted on the output end of the dual-axis motor. Nuts are threaded onto the bidirectional screws and symmetrically distributed. A sliding plate is fixedly connected to the nut. A connecting rod is hinged to the sliding plate. A fastening plate is hinged to the end of the connecting rod away from the sliding plate.

[0007] The fastening plate is equipped with an adjustment component and a limiting component. After the adjustment component contacts the pipe, it causes the limiting component to move and fix the pipe.

[0008] Preferably, an arc-shaped rubber pad is fixedly connected to one side of the fastening plate. The surface of the arc-shaped rubber pad has notches arranged in a linear array along the length of the fastening plate, and the notches make the surface of the arc-shaped rubber pad serrated.

[0009] Preferably, the frame includes two base plates, and a plurality of support rods arranged in a circular array are fixedly connected between the two base plates. A mounting plate fixedly connected to the support rods is provided at the middle position of the two base plates, and the dual-axis motor is mounted on the mounting plate.

[0010] Preferably, the slide plate has an "X" shaped structure, the support rod passes through the slide plate and slides with it, and the end of the bidirectional screw away from the bidirectional motor is rotatably connected to the base plate.

[0011] Preferably, the adjusting assembly includes a receiving box fixedly connected to one side of the fastening plate. A gear is rotatably disposed in the receiving box via a shaft pin. A first toothed plate and a second toothed plate are disposed on both sides of the gear and mesh with the gear. One end of the first toothed plate passes through the receiving box, the fastening plate, and the arc-shaped rubber pad in sequence. The other end of the first toothed plate passes through the receiving box. One end of the second toothed plate passes through the receiving box. A connecting rod that can pass through the receiving box is fixedly connected to the end of the second toothed plate away from the gear.

[0012] Preferably, a limiting rod is fixedly connected inside the receiving box and is arranged parallel to the first toothed plate. A limiting ring connected to the first toothed plate is slidably arranged on the limiting rod. A first spring is provided between one side of the limiting ring and the inner wall of the receiving box and is sleeved on the limiting rod.

[0013] Preferably, the limiting component includes a push plate fixedly connected to the connecting rod, a circular tube fixedly connected to the push plate, a circular ring slidably disposed inside the circular tube, a limiting pin fixedly connected to the inner ring of the circular ring, a second spring disposed between one side of the circular ring and the inner wall of the cylinder, a pull rope fixedly connected to one end of the limiting pin, and the end of the pull rope away from the limiting pin passing through the circular tube.

[0014] Preferably, the second toothed plate has a through hole, and a slide rod passing through the through hole is fixedly connected inside the receiving box. The second toothed plate is limited by the barrel groove and the slide rod.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this application, a dual-axis motor drives a bidirectional screw to move the slide plate and fastening plate quickly, thereby achieving rapid clamping and fixing of the pipe. The arc-shaped rubber pad increases friction through the serrated notch, fixing the pipe from the inside. It can adapt to pipes of different diameters, reduce the frequency of equipment replacement, and reduce construction costs.

[0017] 2. In this application, when the support mechanism is fixed inside the pipe, the adjustment component is adjusted by contacting the pipe, so that the limiting component moves and the pop-out limiting pin limits the pipe. While being fixed inside the pipe, the limiting is performed from the outside, making it less likely to loosen during the lifting process and improving safety performance.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figure 1-8 As shown, this utility model provides a pipe inversion construction device for building pipe wells, including a frame 100, a dual-axis motor 200 mounted on the frame 100, and support mechanisms 300 respectively mounted on the two output ends of the dual-axis motor 200. Each support mechanism 300 includes a bidirectional screw 301 mounted on the output end of the dual-axis motor 200. Nuts 302 are symmetrically distributed and threaded onto the bidirectional screw 301. A sliding plate 303 is fixedly connected to the nut 302. A connecting rod 304 is hingedly mounted on the sliding plate 303. A fastening plate 305 is hingedly mounted on the end of the connecting rod 304 away from the sliding plate 303.

[0030] The fastening plate 305 is equipped with an adjustment component 400 and a limiting component 500. After the adjustment component 400 contacts the pipe, the limiting component 500 is displaced to fix the pipe.

[0031] In this embodiment, an arc-shaped rubber pad 306 is fixedly connected to one side of the fastening plate 305. The surface of the arc-shaped rubber pad 306 has notches arranged in a linear array along the length of the fastening plate 305. The notches make the surface of the arc-shaped rubber pad 306 serrated. When the arc-shaped rubber pad 306 contacts the surface of the pipe, the serrated structure of the notches increases the friction, improves the clamping force, and prevents the pipe from sliding.

[0032] In this embodiment, the frame 100 includes two base plates 101, and a plurality of support rods 102 arranged in a circular array are fixedly connected between the two base plates 101. A mounting plate 103 fixedly connected to the support rods 102 is provided at the middle position of the two base plates 101. A dual-axis motor 200 is mounted on the mounting plate 103. The frame 100 has a stable structure and can withstand a large load.

[0033] In this embodiment, the slide plate 303 has an "X" shaped structure. The support rod 102 passes through the slide plate 303 and slides with it. The end of the bidirectional screw 301 away from the bidirectional motor is rotatably connected to the base plate 101. When the bidirectional screw 301 rotates, it drives the nut 302 and the slide plate 303 to move. The "X" shaped structure of the slide plate 303 increases the contact points with the support rod 102 and improves stability.

[0034] In this embodiment, the adjustment assembly 400 includes a receiving box 401 fixedly connected to one side of the fastening plate 305. A gear 402 is rotatably disposed inside the receiving box 401 via a shaft pin. A first toothed plate 403 and a second toothed plate 404 are disposed inside the receiving box 401 and located on both sides of the gear 402 and meshing with the gear 402. One end of the first toothed plate 403 passes through the receiving box 401, the fastening plate 305 and the arc-shaped rubber pad 306 in sequence. The other end of the first toothed plate 403 passes through the receiving box 401. One end of the second toothed plate 404 passes through the receiving box 401. A connecting rod 405 that can pass through the receiving box 401 is fixedly connected to the end of the second toothed plate 404 away from the gear 402. When the first toothed plate 403 contacts the pipe surface, it is manually squeezed. The first toothed plate 403 moves and, through its engagement with the gear 402, causes the gear 402 to rotate, which in turn drives the second toothed plate 404 to move the connecting rod 405.

[0035] In this embodiment, a limiting rod 406 is fixedly connected inside the receiving box 401 and is arranged parallel to the first toothed plate 403. A limiting ring 407 connected to the first toothed plate 403 is slidably arranged on the limiting rod 406. A first spring 408 is provided between one side of the limiting ring 407 and the inner wall of the receiving box 401 and is sleeved on the limiting rod 406. The limiting ring 407 and the limiting rod 406 limit the first toothed plate 403, and the first spring 408 resets the first toothed plate 403.

[0036] In this embodiment, the limiting component 500 includes a push plate 501 fixedly connected to the connecting rod 405. A circular tube 502 is fixedly connected to the push plate 501. A circular ring 503 is slidably disposed inside the circular tube 502. A limiting pin 504 is fixedly connected to the inner ring of the circular ring 503. A second spring 505 is disposed between one side of the circular ring 503 and the inner wall of the cylinder. A pull rope 506 is fixedly connected to one end of the limiting pin 504. The end of the pull rope 506 away from the limiting pin 504 passes through the circular tube 502. The movement of the connecting rod 405 can drive the push plate 501 to move the circular tube 502 and the limiting pin 504. The limiting pin 504 is dynamically adjusted by the pull rope 506 and the second spring 505. The pull rope 506 can cause the limiting pin 504 to retract inside the circular tube 502, thereby releasing the limitation on the pipe.

[0037] In this embodiment, a through hole 409 is provided on the second toothed plate 404, and a slide rod 410 passing through the through hole 409 is fixedly connected inside the receiving box 401. The second toothed plate 404 is limited by the barrel groove and the slide rod 410.

[0038] How to use and how to work this device:

[0039] When using this device, first pass the frame 100 through the pipe, start the dual-axis motor 200, and the bidirectional screw 301 starts to rotate, driving the nut 302 to move, which in turn drives the slide plate 303 to move and the connecting rod 304 pushes the fastening plate 305 to extend towards the pipe. The arc-shaped rubber pad 306 on the fastening plate 305 contacts the pipe surface, and the serrated structure of the notch increases the friction, fixing the device inside the pipe. It can adapt to pipes of different diameters and lengths, has a wide range of applications, and does not require frequent replacement or adjustment of equipment parts, thus avoiding increased construction time and costs.

[0040] When the support mechanism 300 is fixed inside the pipe, as the fastening plate 305 approaches the pipe, the first toothed plate 403 contacts the pipe before the fastening plate 305. Upon contact with the pipe, the first toothed plate 403 is squeezed and moved, causing the gear 402 to rotate and simultaneously driving the second toothed plate 404 to drive the connecting rod 405 to move the push plate 501. Before the push plate 501 moves, the limiting pin 504 is squeezed inside the round tube 502 by the fastening plate 305. As the push plate 501 moves until the position of the limiting pin 504 is misaligned with the fastening plate 305 and the pipe, the second spring 505 pushes the ring 503 to pop out the limiting pin 504. After popping out, the limiting pin 504 is located on the outer ring of the pipe, limiting the pipe. While being fixed inside the pipe, it is also limited from the outside, making it less likely to loosen during lifting and improving safety performance.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
