Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to an auxiliary connection device for municipal road pipelines. Background Technology

[0002] Municipal road pipelines are an important component of urban infrastructure. Buried beneath municipal roads, pipelines are devices used to transport gases, liquids, or fluids containing solid particles, connected by pipes, pipe fittings, and valves. Grooved pipelines are a type of pipeline system that uses grooved connection technology. Their core feature is the creation of annular grooves at the joints of pipes and fittings, which are then connected using components such as clamps, rubber seals, and fasteners.

[0003] During the installation of trench pipes, a docking device can be used to assist in the docking of the pipes, reducing the difficulty of installation. For example, the utility model patent with publication number CN210232809U discloses a pipe docking auxiliary device, which includes two parallel guide rails. The guide rails are composed of a rack on the left and a round rod on the right. The rightmost end of the guide rail is fixedly connected to a half-ring clamp, and the leftmost end of the guide rail is fixedly connected to a limiting block. The rack end of the guide rail is connected to a docking moving device, which includes a rocker arm. Each end of the rocker arm is fixedly connected to a frame. A pawl is connected to a shaft one inside the frame. The pawl and a ratchet engage. The ratchet is connected to a housing through a shaft two. The housing and the frame are connected through shaft two. The ratchet engages with the rack of the guide rail. The right end of the rectangular housing is fixedly connected to a half-ring clamp two.

[0004] However, this utility model patent still has the following problems: when connecting pipes, the first and second semi-ring clamps can only be inserted into the groove of the upper part of the pipe, while the lower part of the pipe is not fixed, that is, the end of the pipe is in a movable state. If the pipe deviates downward when it moves, the first and second semi-ring clamps will not be able to be effectively inserted into the groove of the pipe, thus requiring multiple adjustments, affecting the normal connection of the pipe and reducing construction efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary docking device for municipal road pipelines, which solves the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A municipal road pipeline auxiliary docking device includes two parallel base plates, each base plate having a support at its bottom. Both base plates share a traction structure and a semi-circular first annular hoop. The traction structure has a second annular hoop with the same diameter as the first annular hoop. Both ends of the first and second annular hoops are rotatably connected to arc-shaped hoops with the same diameter as the first annular hoop. The first annular hoop has a first clamping structure, the second annular hoop has a second clamping structure, and multiple arc-shaped hoops have third clamping structures. The first, second, and third clamping structures are identical in structure and are all designed to fit into grooves on the pipeline. The first and second annular hoops are slidably connected to a limiting structure, which restricts the rotation of the arc-shaped hoop when the third clamping structure on the arc-shaped hoop is embedded in the groove on the pipeline.

[0008] As a preferred embodiment of this utility model, the traction structure includes a traction screw rotatably connected to one of the base plates and a slide rod fixedly connected to the other base plate. The traction screw is threaded with a slide seat that is slidably connected to the corresponding base plate. A connecting seat is slidably sleeved on the slide rod. The two ends of the second annular hoop are respectively fixed to the slide seat and the connecting seat. A crank handle is rotatably connected to one of the base plates. Both the crank handle and the traction screw are fixedly connected with bevel gears, and the two bevel gears mesh with each other.

[0009] In a preferred embodiment of this utility model, the crank handle is fixed to the base plate by a mounting bracket, and the rotation center line of the crank handle is perpendicular to the upper surface of the base plate.

[0010] As a preferred embodiment of the present invention, the first locking structure includes a plurality of locking screws, and each locking screw is rotatably connected to the first annular hoop along the radial direction of the first annular hoop. One end of each locking screw located inside the first annular hoop is rotatably connected to a ball bearing via a mounting seat.

[0011] As a preferred embodiment of this utility model, the limiting structure includes two arc-shaped plates, and the two arc-shaped plates located on the first annular hoop are symmetrical and slidably connected to the outer arc surface of the first annular hoop. The two arc-shaped plates located on the second annular hoop are symmetrical and slidably connected to the outer arc surface of the first annular hoop. Each arc-shaped plate is provided with an annular groove for the locking screw to pass through, and each arc-shaped plate is provided with a locking bolt.

[0012] As a preferred embodiment of this utility model, counterweights can be detachably installed on both base plates.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention involves fitting a first annular hoop and a second annular hoop into the grooves on two pipes, then rotating multiple arc-shaped hoops until a third clamping structure engages with the grooves on the pipes. A limiting structure then restricts the rotation of the arc-shaped hoops, allowing the arc-shaped hoops on both sides of the first and second annular hoops to restrict the lower half of the pipes. This ensures that the first, second, and third clamping structures remain engaged within the grooves of the pipes, enabling the traction structure to effectively pull the pipes for docking and guaranteeing the construction progress.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, this utility model provides an auxiliary docking device for municipal road pipelines, including two parallel base plates 1. Each base plate 1 has a support 11 at its bottom. Both base plates 1 are provided with a traction structure 2 and a semi-circular first annular hoop 3. The traction structure 2 is provided with a second annular hoop 4 with the same diameter as the first annular hoop 3. Both ends of the first annular hoop 3 and the second annular hoop 4 are rotatably connected with arc-shaped hoops 5 with the same diameter as the first annular hoop 3. The first annular hoop 3 is provided with a first clamping structure 6, the second annular hoop 4 is provided with a second clamping structure 8, and multiple arc-shaped hoops 5 are provided with a third clamping structure 9. The first clamping structure 6, the second clamping structure 8, and the third clamping structure 9 have the same structure and are all used to fit into the groove on the pipeline. The first annular hoop 3 and the second annular hoop 4 are slidably connected with a limiting structure 7, and the limiting structure 7 is used to restrict the rotation of the arc-shaped hoop 5 when the third clamping structure 9 on the arc-shaped hoop 5 is embedded in the groove on the pipeline.

[0025] In actual use, the bracket 11 is placed on the ground and supports the two base plates 1. The bottom of the two base plates 1 has space to allow the arc-shaped hoop 5 to rotate, so that one of the pipes (the pipe that does not need to be moved) is located inside the first annular hoop 3 and in contact with the inner side of the first annular hoop 3, and the other pipe that needs to be moved is located inside the second annular hoop 4 and in contact with the inner side wall of the second annular hoop 4. At this time, the first annular hoop 3 and the second annular hoop 4 are respectively located in the grooves on the two pipes.

[0026] Then, rotate the two arc-shaped clamps 5 at both ends of the first annular clamp 3 until they abut against the outer wall of the pipe. Then, the rotation of the two arc-shaped clamps 5 is restricted by the limiting structure 7. Finally, they are engaged into the groove on the pipe by the first clamping structure 6 and the third clamping structure 9. Continue to rotate the two arc-shaped clamps 5 on the second annular clamp 4 until they contact the outer wall of the pipe, and control the second clamping structure 8 and the third clamping structure 9 to engage into the groove on the pipe. The first annular clamp 3 and the second annular clamp 4 respectively cover the upper half of the two pipes. The two arc-shaped clamps 5 on the first annular clamp 3 and the two arc-shaped clamps 5 on the second annular clamp 4 abut against the lower half of the corresponding pipes, and are engaged into the groove of the pipe by the first clamping structure 6, the second clamping structure 8 and the third clamping structure 9, so that the end of the pipe is fixed and the pipe will not detach. This ensures that the pipe is always pulled by an external force during the docking process, thereby ensuring construction efficiency.

[0027] After the pipe is fixed, the traction structure 2 pulls the second annular hoop 4 to move, thereby driving the pipe to move synchronously to another pipe for docking. After docking, the limiting structure 7 releases the restriction on the arc hoop 5. At this time, the entire device can be lifted so that the pipe passes between the two base plates 1. The pipe can continue to carry out subsequent installation procedures. The arc hoop 5 does not contact the bottom of the pipe, so it will not interfere with the ground when flipped, which improves the convenience of use. In addition, there is enough space on the side of the arc hoop 5 to facilitate the use of the third clamping structure 9.

[0028] The third clamping structure 9 can be used before the arc-shaped clamp 5 rotates to abut against the pipe, or after the arc-shaped clamp 5 abuts against the pipe.

[0029] In this embodiment, the first annular hoop 3 and the second annular hoop 4 are both semi-annular plates, and the arc-shaped hoop 5 is an arc-shaped plate.

[0030] The traction structure 2 includes a traction screw 201 rotatably connected to one of the base plates 1 and a slide rod 205 fixedly connected to the other base plate 1. The traction screw 201 is threadedly connected to a slide seat 202 that is slidably connected to the corresponding base plate 1. A connecting seat 206 is slidably sleeved on the slide rod 205. The two ends of the second annular hoop 4 are respectively fixed to the slide seat 202 and the connecting seat 206. A crank handle 203 is rotatably connected to one of the base plates 1. Both the crank handle 203 and the traction screw 201 are fixedly connected to bevel gears 204, and the two bevel gears 204 mesh with each other.

[0031] The worker turns the crank handle 203, which drives one of the bevel gears 204 to rotate. Through the meshing relationship, the bevel gear 204 on the traction screw 201 rotates, thereby driving the traction screw 201 to rotate. The rotation of the traction screw 201 drives the slide block 202 to move, thereby pulling the second annular hoop 4 to move. The slide rod 205 is used to support the movement of the connecting seat 206, and the connecting seat 206 supports the movement of the second annular hoop 4 to ensure the stability of the movement.

[0032] The crank handle 203 is fixed to the base plate 1 by a mounting bracket, and the rotation center line of the crank handle 203 is perpendicular to the upper surface of the base plate 1.

[0033] The crank handle 203 is located above the base plate 1 for easy use by workers.

[0034] The first locking structure 6 includes a plurality of locking screws 601, and each locking screw 601 is rotatably connected to the first annular hoop 3 through the radial direction of the first annular hoop 3. One end of each locking screw 601 located inside the first annular hoop 3 is rotatably connected to a ball bearing 602 through a mounting seat.

[0035] By rotating the locking screws 601 in sequence, multiple locking screws 601 move into the grooves on the pipe, thereby sequentially embedding multiple balls 602 into the grooves on the pipe. This allows the balls 602 to be prevented from disengaging along the axial direction of the pipe by the grooves on the pipe. Combined with the third clamping structure 9 being embedded in the grooves on the pipe, the pipe can be fixed inside the first annular clamp 3. Similarly, the second clamping structure 8 is also embedded in the grooves on the pipe.

[0036] The limiting structure 7 includes two arc-shaped plates 701. The two arc-shaped plates 701 located on the first annular hoop 3 are symmetrical and slidably connected to the outer arc surface of the first annular hoop 3. The two arc-shaped plates 701 located on the second annular hoop 4 are symmetrical and slidably connected to the outer arc surface of the first annular hoop 3. Each arc-shaped plate 701 is provided with an annular groove 702 for the locking screw 601 to pass through. Each arc-shaped plate 701 is provided with a locking bolt.

[0037] When the arc-shaped clamp 5 rotates to abut against the pipe, the sliding arc-shaped plate 701 slides to the outer surface of the arc-shaped clamp 5, thereby restricting the arc-shaped clamp 5 from rotating in a direction away from the pipe. This restricts the pipe to the inside of the arc-shaped clamp 5 and the first annular clamp 3 (or the second annular clamp 4). The arc-shaped plate 701 is then fixed by the locking bolt, ensuring the stability of the limiting structure 7 when restricting the rotation of the arc-shaped clamp 5. The locking screw 601 passes through the annular groove 702 and can move within the annular groove 702, avoiding interference between the arc-shaped plate 701 and the locking screw 601 when the arc-shaped plate 701 moves.

[0038] Counterweights 10 can be detachably installed on both base plates 1.

[0039] To improve the stability of the entire device, the counterweight 10 is detachable and can be moved separately, which facilitates the movement of the entire device. The counterweight 10 can be detachably installed on the base plate 1 by plugging it in.

Any person skilled in the art can make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in the present utility model, but these should still be regarded as the same technology or embodiment as the present utility model.
