Description

Technical Field

[0001] This utility model relates to the field of building pipeline construction, and in particular to an underground pipeline construction splicing device. Background Technology

[0002] Rubber flexible bendable pipes are widely used in underground drainage construction. Their flexible structure adapts to complex terrain, bending to avoid underground obstacles and reducing excavation. The material is acid and alkali resistant and corrosion resistant, adapting to different media such as sewage and rainwater, extending its service life. The joint adopts a socket design, providing good sealing performance and effectively preventing leakage. Lightweight, they are convenient for transportation and installation, reducing construction intensity. Simultaneously, they possess good anti-settlement capabilities, are not easily broken when the foundation deforms, ensuring the stable operation of the drainage system. Suitable for municipal pipe networks, residential drainage, and agricultural irrigation, they are an efficient and durable underground drainage solution. Currently, when laying this type of pipe, the dead point position of a four-bar linkage is used to clamp the pipe. A rope device is combined with the clamping device to lift the pipe and achieve pipe splicing (see invention patent application number CN201811515803.5). This method has the problem of cumbersome arrangement of the clamping device and rope on the pipe; improper installation can easily lead to uneven stress on the pipe, making it impossible to guarantee coaxiality. Repeated adjustments are required during the splicing process, which needs improvement. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an underground pipeline construction splicing device.

[0004] The technical solution of this utility model is: an underground pipeline construction splicing device, including two guide rails arranged in this configuration, a U-shaped handle, a first semicircular hoop, and a second semicircular hoop. The two hoops are of the same size and are concentrically arranged.

[0020] Example 1, see appendix Figure 1-2 An underground pipeline construction splicing device includes two guide rails 1, a U-shaped handle 2, a first semicircular hoop 31, and a second semicircular hoop. The first semicircular hoop 31 is connected between the two guide rails 1. A sliding sleeve is provided on the guide rail, which can slide along the guide rail 1. The second semicircular hoop is connected between the two sliding sleeves. As the sliding sleeve moves along the guide rail 1, the first semicircular hoop 31 and the second semicircular hoop can move towards or away from each other. The surface of the guide rail 1 is provided with teeth 11. The upper end of the sliding sleeve is provided with a drive wheel 41 that matches the teeth 11 through a wheel axle 42. The drive wheel 41 moves along the guide rail 1 and moves the sliding sleeve synchronously. The lower end of the U-shaped handle 2 is provided with a U-shaped fork 51. The two ends of the U-shaped fork 51 are rotatably connected to the two wheel axles 42. A push plate 52 is hinged in the middle of the U-shaped fork 51. The outer end of the push plate 52 is provided with an inwardly bent push head 53. The push head 53 matches the size of the tooth groove on the drive wheel 41.

[0021] The hinge of the push plate 52 is provided with a first torsion spring 54. One end of the first torsion spring 54 is supported on the side of the U-shaped fork 51, and the other end is supported in the middle of the push plate 52. The first torsion spring 54 provides the push plate 52 with an inward rotational torque, so that the push head 53 at its end can press against the tooth groove on the drive wheel 41 to ensure the driving effect.

[0022] A positioning toothed plate 55 is rotatably connected to one end of the sliding sleeve. The outer end of the positioning toothed plate 55 is matched and supported in the tooth groove of the drive wheel 41. A second torsion spring 56 is installed on the rotating part of the positioning toothed plate 55. One end of the second torsion spring is supported in the middle of the positioning toothed plate, and the other end is supported on the end face of the sliding sleeve. The second torsion spring 56 provides inward pressure to the positioning toothed plate 55, so that its outer end can be pressed tightly in the tooth groove of the drive wheel 41.

[0023] After the pusher plate 52 pushes the drive wheel 41 to rotate once, the positioning tooth plate 55 falls into the groove on the drive wheel 41, providing a limit brake for the drive wheel, preventing the reaction force generated by the tension of the pipeline from causing the drive wheel 41 to move in the opposite direction along the track, thus improving the driving efficiency.

[0024] When using the underground pipeline construction splicing device of this embodiment, the first semicircular hoop 31 is fitted into the annular groove on one side of the pipeline, and the second semicircular hoop is fitted into the annular groove on the other side of the pipeline. After the installation is secure, press the U-shaped handle 2. The push plate 52 in the U-shaped fork 51 at the lower end of the U-shaped handle 2 will then push downward into the tooth groove on the drive wheel 41. The drive wheel 41 moves along the teeth 11 on the guide rail 1. When the U-shaped handle 2 is lifted upward, the push head 53 at the outer end of the push plate 52 leaves the tooth groove on the drive wheel 41. By repeatedly pressing the U-shaped handle 2, the drive wheel 41 can move continuously along the track, thereby driving the sliding sleeve to slide along the guide rail 1. The semicircular hoop moves accordingly to drive the two pipelines to move towards each other, thus achieving splicing. This device is convenient to install and use on pipelines. The semicircular hoop makes the pipeline uniformly stressed and has high coaxiality, which can effectively improve the splicing efficiency and quality.

[0025] Example 2, see appendix Figure 1 , 3 -5. This embodiment is basically the same as embodiment one, and the similarities will not be repeated. The difference is that the gate-shaped handle 2 includes two symmetrically arranged L-shaped tubes 21 and sleeves 22. The upper end of the L-shaped tube is inserted into the port of the two sleeves. The depth of the L-shaped tube 21 inserted into the sleeve 22 is different, which can change the width of the gate-shaped handle 2, thereby changing the distance between the two guide rails 1. The first semi-circular hoop 31 and the second semi-circular hoop of the corresponding size are installed between the guide rails 1 and between the sliding sleeves, which can be used for the splicing operation of pipes of different sizes.

[0026] The upper part of the sleeve 22 and the L-shaped tube 21 is provided with several positioning holes 23 at equal intervals. Inside the L-shaped tube 21, there is a flexible positioning pin 24. The positioning pin 24 is inserted between two corresponding positioning holes 23 to lock the sleeve 22 and the L-shaped tube 21. After the insertion depth of the two L-shaped tubes and the sleeve is changed, the positioning pin 24 and the positioning holes 23 lock the two together, ensuring the stability after the width of the gate-shaped handle 2 is adjusted.

[0027] A rubber positioning block 25 is provided at the lower end of the positioning pin 24, and a support sleeve 26 is provided radially inside the L-shaped tube 21. A spring 27 is connected between the rubber positioning block 25 and the positioning pin 24. The rubber positioning block 25 is fixed to the bottom of the support sleeve 26. The rubber positioning block is fixed in the support sleeve by elastic deformation, thereby connecting the spring 27 and the positioning pin 24 to the support sleeve 26 to prevent slippage. When the L-shaped tube 21 moves with the positioning pin 24 and contacts the sleeve 22, the positioning pin 24 will compress the spring 27 and enter the support sleeve 26, so that the L-shaped tube 21 and the sleeve 22 can slide normally. When it corresponds to the next positioning hole 23, it will extend again under the action of the spring 27 to achieve locking.
