Description

Technical Field

[0001] This utility model relates to the field of pipe jacking technology, and to a convenient pipe jacking cleaning device. Background Technology

[0002] Pipe jacking is a construction method that uses jacking equipment within a working shaft to overcome the friction between the pipe and the surrounding soil, pushing the pipe into a predetermined position and removing soil and other debris. When the total length of the pipe jacking project is long, grouting holes need to be pre-installed on some pipe sections to facilitate the spraying of bentonite grout onto the outside of the pipe. This forms a grout film on the outer wall of the pipe section, which serves to lubricate, reduce frictional resistance, and facilitate pipe jacking.

[0003] During the pipeline prefabrication process, cement slurry or other impurities can easily get into the grouting holes, making it difficult to install grouting nozzles or plugs. Therefore, before the jacking pipe is moved into the working shaft, the grouting holes on the pipe section need to be cleaned to facilitate the installation of grouting nozzles or plugs.

[0004] Currently, in pipe jacking projects, dozens or even more grouting pipe sections are usually used, and each grouting pipe section usually has 6-8 grouting holes. Although general tools can clean the grouting holes on the pipe sections, the manual operation by workers is time-consuming, labor-intensive, and inefficient, and needs to be improved. Utility Model Content

[0005] To address the aforementioned technical problems in existing technologies, a convenient pipe jacking cleaning device is provided, which solves the problems of time-consuming, labor-intensive, and inefficient cleaning of grouting holes on pipe sections.

[0006] The purpose and effects of this utility model are achieved by the following specific technical means:

[0007] A convenient pipe jacking cleaning device includes: a base, a transverse drive component, a support component, a longitudinal drive component, a tap, and a hole cleaning station. The transverse drive component is mounted on the base, the support component is fixed on the transverse drive component, the longitudinal drive component is mounted on the support component, and the tap is fixed to the output end of the longitudinal drive component. The tap is used to clean the grouting holes on the pipe section. Multiple hole cleaning stations are provided and all are mounted on the base. The tap is located above the hole cleaning station, and the hole cleaning station is used to support the pipe section and drive the pipe section to rotate.

[0008] Furthermore, the lateral drive component includes a screw rotatably mounted on the top of the base via a bearing seat, a first geared motor fixed to the top of the base, and a slide block slidably connected to the top of the base. One end of the screw is fixedly connected to the output end of the first geared motor, a nut is fitted onto the screw, the bottom of the slide block is fixedly connected to the nut, and the support member is fixed on the slide block.

[0009] Furthermore, the support includes a bracket fixed to the slide and a plate fixed to the top of the bracket, and the longitudinal drive component is fixed to the plate.

[0010] Furthermore, the longitudinal drive component includes a first electric cylinder fixed on a flat plate, a lifting frame fixed to the output end of the first electric cylinder, and a second motor fixed inside the lifting frame. The output shaft of the second motor extends out of the lifting frame and is fixedly connected to a tap.

[0011] Furthermore, the hole cleaning station includes two rollers rotatably mounted on the top of the base via bearing seats and a third geared motor fixed on the top of the base. The two rollers are parallel to each other, and a sprocket is fixed to one end of each roller. The two sprockets are connected by a chain drive, and the other end of one roller is fixedly connected to the output end of the third geared motor.

[0012] Furthermore, a movable plate is provided below the flat plate, and two pressure rollers are fixedly connected to the bottom of the movable plate. The two pressure rollers are symmetrically distributed on both sides of the tap. An opening slot adapted to the hanging frame is provided through the top of the movable plate. Multiple second electric cylinders are fixedly installed on the top of the flat plate, and the output ends of the second electric cylinders are all fixedly connected to the top of the movable plate.

[0013] Furthermore, multiple guide rods are slidably threaded through the top of the plate, and the bottom ends of the guide rods are fixedly connected to the top of the hanging frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The hole cleaning station in this portable pipe jacking cleaning device is used to support and drive the pipe section to rotate. The position of the grouting holes on the pipe section can be adjusted so that the tap can clean the grouting holes in different positions of the pipe section laterally. When the lateral drive component works, it will drive the support component, the longitudinal drive component and the tap to move laterally together. When the longitudinal drive component works, it will drive the tap to move longitudinally, so as to change the lateral and longitudinal displacement of the tap, thereby achieving lateral cleaning of the grouting holes on multiple pipe sections. The grouting hole cleaning is convenient and greatly improves the grouting hole cleaning efficiency. The entire operation does not require manual cleaning by the staff, reducing the workload of the staff. Attached Figure Description

Detailed Implementation

[0020] Please see Figure 1-3 The embodiments of this utility model will be further described below;

[0021] A convenient pipe jacking cleaning device includes: a base 1, a transverse drive component, a support component, a longitudinal drive component, a tap 13, and cleaning stations 19. The transverse drive component is mounted on the base 1, the support component is fixed to the transverse drive component, the longitudinal drive component is mounted on the support component, and the tap 13 is fixed to the output end of the longitudinal drive component. The tap 13 is used to clean the grouting holes 24 on the pipe section 23. Multiple cleaning stations 19 are provided and all are mounted on the base 1. The tap 13 is located above the cleaning stations 19. The cleaning stations 19 are used to support the pipe section 23 and drive the pipe section 23 to rotate. Adjustable pipe... The position of the grouting holes 24 on section 23 is determined so that the tap 13 can clean the grouting holes 24 in different positions on section 23 laterally. When the lateral drive component works, it will drive the support, the longitudinal drive component and the tap 13 to move laterally together. When the longitudinal drive component works, it will drive the tap 13 to move longitudinally, so as to change the lateral and longitudinal displacement of the tap 13, thereby achieving the lateral cleaning of the grouting holes 24 on multiple sections 23. The grouting holes 24 are easy to clean, which greatly improves the cleaning efficiency of the grouting holes 24. The whole operation does not require manual cleaning by the staff, reducing the workload of the staff.

[0022] The lateral drive component includes a screw 4 rotatably mounted on the top of the base 1 via a bearing seat, a first reduction motor 6 fixed to the top of the base 1, and a slide block 7 slidably connected to the top of the base 1. Specifically, guide rails 2 are fixedly connected to both sides of the top of the base 1 on the screw 4, and sliders 3 are slidably sleeved on the guide rails 2. The sliders 3 are fixedly connected to the bottom of the slide block 7. One end of the screw 4 is fixedly connected to the output end of the first reduction motor 6, and a nut 5 is fitted onto the screw 4. The bottom of the slide block 7 is fixedly connected to the nut 5, and the support is fixed on the slide block 7.

[0023] The support includes a bracket 8 fixed to the slide 7 and a plate 9 fixed to the top of the bracket 8, and the longitudinal drive component is fixed to the plate 9.

[0024] The longitudinal drive component includes a first electric cylinder 10 fixed on the plate 9, a lifting frame 11 fixed to the output end of the first electric cylinder 10, and a second motor 12 fixed inside the lifting frame 11. The output shaft of the second motor 12 extends out of the lifting frame 11 and is fixedly connected to the tap 13.

[0025] The hole cleaning station 19 includes two rollers 20 rotatably mounted on the top of the base 1 via bearing seats and a third geared motor 22 fixed on the top of the base 1. The two rollers 20 are parallel to each other, and a sprocket 21 is fixed to one end of each roller 20. The two sprockets 21 are connected by chain drive, and the other end of one roller 20 is fixedly connected to the output end of the third geared motor 22.

[0026] The working principle of this solution is as follows:

[0027] The pipe section 23, whose grouting hole 24 needs to be cleaned, is placed between two rollers 20 on the cleaning station 19. The two rollers 20 support the pipe section 23, ensuring that one of the grouting holes 24 on the pipe section 23 faces upwards. Figure 1 and 2 As shown, the first reduction motor 6 in the transverse drive component is started. The first reduction motor 6 drives the screw 4 to rotate to provide power to the slide 7. The slide 7 will drive the slider 3 at its bottom to slide on the guide rail 2, thereby driving the support, the longitudinal drive component and the tap 13 to move laterally together.

[0028] When tap 13 moves below the upward-facing grouting hole 24, the first reduction motor 6 is turned off, and then the second motor 12 in the lifting frame 11 and the first electric cylinder 10 on the plate 9 are started. The first electric cylinder 10 will drive the lifting frame 11, the second motor 12, and tap 13 to move downward, gradually approaching the grouting hole 24. The second motor 12 will drive tap 13 to rotate. As tap 13 moves downward and rotates, it can clean out the cement slurry or other impurities in the grouting hole 24. Afterward, the first electric cylinder 10 will drive the lifting frame 11, the second motor 12, and tap 13 upward. Move away from the cleaned grouting hole 24, turn off the second motor 12, and then start the third reduction motor 22 to drive the connected idler roller 20 to rotate. Through the sprocket 21 and chain, the other idler roller 20 will rotate synchronously, thereby promoting the pipe section 23 to rotate between the two idler rollers 20. By rotating the pipe section 23, the other grouting hole 24 at this location can be turned upwards. Turn off the third reduction motor 22, and continue to start the second motor 12 to complete the cleaning of the second grouting hole 24. The remaining grouting holes 24 at this location can be cleaned by following the above operation.

[0029] While cleaning the first pipe section 23, the worker can place the second pipe section 23 on another hole cleaning station 19. After the grouting hole 24 on the first pipe section 23 is cleaned, the first reduction motor 6 can be started to drive the tap 13 to move laterally. The specific operation will not be described in detail. During this process, the first pipe section 23 is taken out. Thus, the grouting holes 24 on multiple pipe sections 23 can be cleaned continuously. The operation is simple and convenient for cleaning the grouting holes 24, which greatly improves the cleaning efficiency of the grouting holes 24. The entire operation does not require manual cleaning by the workers, which reduces the workload of the workers.

[0030] To enhance the stability of pipe section 23 on the two idler rollers 20, a movable plate 16 is provided below the plate 9. Two pressure rollers 17 are fixedly connected to the bottom of the movable plate 16, and the two pressure rollers 17 are symmetrically distributed on both sides of the tap 13. An opening slot 18 adapted to the lifting frame 11 is provided through the top of the movable plate 16 so that the lifting frame 11 can pass through the opening slot 18 when moving longitudinally. Multiple second electric cylinders 15 are fixedly installed on the top of the plate 9, and the output ends of the second electric cylinders 15 are all connected to the movable plate 16. When the top of the pipe section 23 is fixedly connected, multiple second electric cylinders 15 are activated to drive the movable plate 16 to move down. The movable plate 16 will then drive the two pressure rollers 17 to gradually approach the pipe section 23. When the two pressure rollers 17 limit the pipe section 23, the multiple second electric cylinders 15 are turned off. If it is necessary to release the limit, the multiple second electric cylinders 15 are activated directly to drive the movable plate 16 and the two pressure rollers 17 to move up, so that the limit can be released, and the pipe section 23 can be rotated through the hole cleaning station 19 later.

[0031] To enhance the stability of the longitudinal movement of the hanging frame 11, multiple guide rods 14 are slidably inserted through the top of the plate 9. The bottom end of the guide rod 14 is fixedly connected to the top of the hanging frame 11. When the hanging frame 11 moves, it will drive the guide rod 14 to move on the plate 9, which can limit the movement of the plate 9.
