Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking machines, in particular to a power cable retracting and releasing device for a pipe jacking machine. Background Art

[0002] The power cable retracting and releasing device of the pipe jacking machine is an indispensable key equipment in the pipe jacking operation. With the acceleration of urbanization, the demand for underground pipeline construction is growing. As a trenchless construction method, pipe jacking technology has significant advantages. However, in traditional pipe jacking operations, the retraction and release of power cables and soil transportation often rely on manual operations, which are inefficient and pose safety hazards.

[0003] During the construction of the rectangular pipe jacking machine, the power cable needs to be continuously retracted and released due to the extension of the pipe sections and the cables must pass through the newly installed pipe sections. The power cable needs to be removed once for each next pipe section and the cable of the main machine needs to be extended. Manual removal of the cable is not only time-consuming and labor-intensive, but also has high safety risks. Utility Model Content

[0004] Based on the above description, the utility model provides a power cable retracting and releasing device for a pipe jacking machine to solve the problem that the existing power cable retracting and releasing device for a pipe jacking machine is inconvenient in retracting and releasing the cable.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A power cable retracting and releasing device for a pipe jacking machine comprises a pipe jacking body, a surface of one side of the pipe jacking body being clamped with a plurality of pipe sections which can be installed in a stacked manner, a pipe jacking machine body which can push the pipe jacking body to move is provided on one side of the pipe jacking body, a retracting and releasing mechanism which can facilitate the retracting and releasing of the cable is provided inside the pipe jacking body, an unearthing mechanism which transports soil out of the equipment is also provided inside the pipe jacking body, and an isolation component which prevents the retracting and releasing mechanism and the transport mechanism from interfering with each other is also provided inside the pipe jacking body.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the retracting and releasing mechanism includes a moving trolley, which is located on the inner bottom surface of the top tube body. The moving trolley can be driven by a signal through a remote control. An electric reel is fixedly installed on the upper surface of the moving trolley. A cable is wound on the surface of the electric reel. An aviation plug is provided at one end of the cable. The cable can be connected to the incoming cable outside the equipment through the aviation plug.

[0009] Furthermore, the excavation mechanism includes two soil transport pipes, which are respectively connected to one side of an earth entry port, a friction ring is arranged inside the soil transport pipe, and an excavation hole is opened at one end of the soil transport pipe. The excavation mechanism also includes a soil loading vehicle, which is located inside the jacking pipe body.

[0010] Furthermore, the isolation component includes an isolation plate, which separates the bottom of the top tube body into a trolley track and a transport track, and a slidable limiting component is also provided on the upper surface of the isolation component.

[0011] Furthermore, the limiting component is used to limit the moving distance of the retracting and releasing mechanism, a plurality of fixing holes are provided on the side surface of the isolation plate, and a slidable limiting baffle is provided on the upper surface of the isolation plate.

[0012] Furthermore, the limiting assembly also includes: a limiting plate, which is fixedly mounted on a side surface of the moving vehicle and slides on the upper surface of the isolation plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] By setting up a retracting and releasing mechanism, during the process of installing a new pipe section by jacking, the cable can be released or recovered by the electric reel according to the jacking progress, which greatly shortens the operation time. At the same time, the excavation mechanism can continuously and efficiently dig out the soil and transport it to the outside after crushing the soil through the friction ring, avoiding the impact of soil accumulation on the operation progress. This design significantly improves the efficiency of the jacking operation, reduces labor intensity, and makes the operation process smoother.

[0015] In this solution, the isolation component and the limiting component work together to effectively isolate the retracting and extending mechanism from the excavation mechanism, ensuring that the two do not interfere with each other. The isolation plate divides the bottom of the pipe jacking machine into different areas, allowing the mobile trolley and the soil loader to slide stably on their respective tracks. The setting of the limiting component limits the moving distance of the mobile trolley, preventing the retracting and extending mechanism from interfering with the excavation mechanism, thereby improving the safety of the operation.

[0029] The retracting and releasing mechanism includes a mobile trolley 7, which is located on the inner bottom surface of the top tube body 1. The mobile trolley 7 can be driven by a signal through a remote control. A battery 14 for providing power to the mobile trolley 7 is fixedly installed on the upper surface of the mobile trolley 7. An electric reel 13 is fixedly installed on the upper surface of the mobile trolley 7. A rotatable take-up reel is provided at the center of the electric reel 13. A cable 15 is wound on the surface of the take-up reel. One end of the cable 15 is connected to the main motor inside the top tube body 1, and the other end is provided with an aviation plug 16. The cable 15 can be connected to the incoming cable outside the equipment through the aviation plug 16.

[0030] The excavation mechanism includes two soil transport pipes 12, which are respectively connected to one side of a soil entry port 5. A friction ring 18 is arranged inside the soil transport pipe 12, and an excavation hole 17 is opened at one end of the soil transport pipe 12. The excavation mechanism also includes a soil loader 11, which is located inside the top pipe body 1 and can slide on the bottom surface inside the top pipe body 1. The soil loader 11 is located below the two excavation holes 17; the isolation component includes an isolation plate 6, which divides the bottom of the top pipe body 1 into a trolley runway 9 and a transport path 10. The mobile trolley 7 slides on the upper surface of the trolley runway 9, and the soil loader 11 slides on the upper surface of the transport path 10. A slidable limiting component is also provided on the upper surface of the isolation component.

[0031] The retraction and release of the power cable is completed by the retraction and release mechanism. The mobile trolley 7 is driven by a remote control to move on the trolley runway 9 inside the jacking pipe body 1. The electric reel 13 installed on the mobile trolley 7 is powered by a battery 14. A rotatable take-up drum is arranged at the center of the electric reel 13. A cable 15 is wound on the take-up drum. One end of the cable 15 is connected to the main motor inside the jacking pipe body 1, and the other end is provided with an aviation plug 16, which can be connected to the incoming cable outside the equipment. When the next pipe section is needed, the aviation plug of the cable retraction and release device is unplugged, and the incoming cable end can be recovered. When the pipe section is placed in place, the aviation plug is plugged in to start jacking. According to the progress of the jacking of the pipe jacking machine, the remote control electric reel releases the cable, and the electric reel 13 drives the take-up drum to rotate to realize the retraction and release of the cable 15. When entering the next cycle, the mobile trolley 7 moves to a suitable position along the trolley runway 9 according to the instruction, and the cable reel is driven to move to the predetermined position of the new pipe section by the remote control electric flatbed car, so that the length of the aviation plug incoming line can be reduced.

The limiting component also includes a limiting plate 8, which is fixedly mounted on one side surface of the moving trolley 7 and slides on the upper surface of the isolation plate 6 through a slide groove provided at the bottom.

[0033] The working principle of the utility model is:

[0034] The retraction and release of the power cable is completed by the retraction and release mechanism. The mobile trolley 7 is driven by a remote controller to move on the trolley runway 9 inside the jacking body 1. The electric reel 13 installed on the mobile trolley 7 is powered by a battery 14. The power cable retraction and release device of the jacking machine realizes the automation and efficiency of the retraction and release of the power cable and the soil transportation in the jacking operation through an integrated design. The working process of the device is mainly divided into three links: the retraction and release of the power cable, the transportation of the soil, and the coordinated work of the isolation component and the restriction component.

[0035] Soil transportation is completed through the excavation mechanism. During the jacking operation, the toothed disc 4 rotates to dig out the soil, and enters the soil transport pipe 12 through the soil entry port 5. The friction ring 18 inside the soil transport pipe 12 increases the friction between the soil and the pipe wall, making the soil more fine and able to move smoothly along the soil transport pipe 12. The soil is finally discharged through the excavation hole 17 and falls on the soil loader 11. The soil loader 11 slides on the transport path 10 and transports the soil to the outside of the jacking pipe body 1 for processing.

[0036] The isolation component and the limiting component work together to ensure that the retracting mechanism and the excavation mechanism do not interfere with each other. The isolation plate 6 divides the bottom of the interior of the jacking pipe body 1 into a trolley runway 9 and a transport track 10. The mobile trolley 7 slides on the trolley runway 9, and the loader 11 slides on the transport track 10. The limiting baffle 19 in the limiting component is fixed to the isolation plate 6 by the fixing bolt 21, and cooperates with the limit plate 8 to limit the moving distance of the mobile trolley 7 to prevent the retracting mechanism from interfering with the work of the excavation mechanism. At the same time, the setting of the limiting component also ensures that the retracting mechanism retracts and releases the cable in the appropriate position, thereby improving the safety and efficiency of the operation.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
