Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, and in particular to a flushing pipe that facilitates cleaning the inner wall of the pipe. Background Technology

[0002] Based on their working principles, tunnel boring machines (TBMs) are generally classified into manual TBMs, extrusion TBMs, semi-mechanical TBMs, and mechanical TBMs. Modern TBMs integrate optics, mechanics, electronics, hydraulics, sensing, and information technology, and have functions such as excavating and cutting soil, transporting excavated material, assembling tunnel lining, and measuring, guiding, and correcting deviations.

[0003] According to patent publication number CN213915295U, a flushing pipe for easy cleaning of the inner wall of a tunnel boring machine (TBM) is disclosed. The pipe includes a body and a slot. A first motor is installed on one side of the body, and a telescopic pipe connects the regulating box to the body. A fixing block is fixed to one end of the flushing pipe, and a locking block is connected to one end of a spring. The slot near the locking block is located on one side of the fixing block. This flushing pipe for easy cleaning of the inner wall of the TBM includes an regulating box and a telescopic pipe. When the first motor is started, it drives a first rotating shaft to rotate. The rotation of the first rotating shaft drives the regulating box to rotate. When the regulating box rotates, it deforms the telescopic pipe. Water flowing into the telescopic pipe is blocked at one end by a second baffle, causing the water flowing into the inner wall of the flushing pipe to flow out through a filter plate for rinsing. The rotation of the regulating box changes the orientation of the flushing pipe inside the regulating box, thereby changing the rinsing angle of the flushing pipe for easy adjustment.

[0004] However, the second baffle in the above application is fixed by a connection between a clip and a slot. However, the clip and the slot are connected by a tenon joint. It is difficult for the cleaner to push open the second baffle. After long-term use, impurities will gradually accumulate in the slot, making it difficult to insert the clip into the slot. As a result, the second baffle will not be closed, thus affecting the protection. Summary of the Invention

[0005] One of the objectives of this invention is to provide a flushing pipe that facilitates cleaning of the inner wall of the pipe.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flushing pipe that facilitates cleaning of the inner wall of a pipe, comprising a second baffle, a cleaning plug, and a flushing pipe body. An outer plate is provided on the flushing pipe body, and a sliding rod is slidably connected to the outer plate. One end of the sliding rod is connected to the second baffle. An insert plate is provided on the second baffle. A socket is provided on the flushing pipe body in the direction of movement of the insert plate, and a top seat is connected to the socket. The top seat is slidably connected to the side wall of the flushing pipe body.

[0007] Preferably, a baffle is provided at the other end of the slide rod, the diameter of the baffle being larger than the diameter of the slide rod, and a first return spring is sleeved on the slide rod between the baffle and the outer plate.

[0008] Preferably, the insert plate is connected through the outer plate, the insert plate has a slot, and the end of the insert plate facing the socket is connected to a bevel.

[0009] Preferably, the flushing pipe body has a horizontal groove, and a guide rod is installed in the horizontal groove.

[0010] Preferably, a guide plate is slidably connected to the guide rod, a second return spring is sleeved on the guide rod below the guide plate, and the guide plate is connected to the connecting seat.

[0011] Preferably, one end of the connector is connected to a socket, and the other end of the connector is connected to a top seat, the top seat being arc-shaped toward the end of the cleaning plug.

[0012] Preferably, the socket is arranged in a U-shape, a plug is inserted into the socket, and a locking head is provided at the top of the socket, which is engaged in the locking slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This flushing pipe facilitates cleaning of the inner wall of the pipe. An outer plate is installed on the main body of the flushing pipe, and a sliding rod can be mounted on the outer plate. One end of the sliding rod is connected to a second baffle. The second baffle moves horizontally via the sliding rod, thus moving in the same direction as the cleaning plug. An insert plate is connected to the second baffle, and a socket is positioned in the direction of the insert plate's movement. The socket is located in a transverse groove within the main body of the flushing pipe and is connected to a top seat via a connecting seat. The top seat is located within the main body of the flushing pipe. When the cleaning plug moves to the top seat, it actuates the top seat, causing it to move into the transverse groove. When the cleaning plug resets, the top seat also resets. As the top seat moves into the transverse groove, the socket moves upward, causing the locking head to disengage from the locking slot, thus freeing the insert plate from restriction. When the cleaning plug pushes impurities to the position of the second baffle, the second baffle is pushed open by the easy movement of the cleaning plug, thereby cleaning the impurities. After the cleaning plug resets, the second baffle is reset by the action of a first reset spring, thus achieving protection of the pipe with the second baffle. At this time, the insert plate is reinserted into the socket for fixation, ensuring the stability of the second baffle during protection. Attached Figure Description

[0024] like Figures 1 to 5As shown, the present invention provides a flushing pipe for easy cleaning of the inner wall of a pipe, comprising a second baffle 1, a cleaning plug 3, and a flushing pipe body 2. An annular outer plate 4 is fixedly mounted on the flushing pipe body 2. Multiple sliding rods 5 are slidably connected through the outer plate 4. One end of each sliding rod 5 is fixedly connected to the second baffle 1. The second baffle 1 is disc-shaped and rests against one end of the flushing pipe body 2. A large number of filter holes are provided in the middle of the second baffle 1, all of which communicate with the port of the flushing pipe body 2. An insert plate 10 is fixedly connected to the second baffle 1, penetrating the side wall of the outer plate 4. A long, horizontal groove 6 is opened on the flushing pipe body 2 in the direction of movement of the insert plate 10. A socket 12 is provided in the horizontal groove 6, and a top seat 9 is fixedly connected to the bottom side of the socket 12. The top seat 9 vertically penetrates... The top seat 9 is slidably connected to the side wall of the flushing pipe body 2. In its natural state, the bottom part of the top seat 9 is located inside the flushing pipe body 2. When cleaning the pipe, the cleaning plug 3 pushes the impurities towards the position of the second baffle 1. When the cleaning plug 3 moves to the position of the top seat 9, it pushes the top seat 9 into the transverse groove 6. At this time, the top seat 9 will be pushed out and remain stationary, and the insert plate 10 will disengage from the socket 12. As the cleaning plug 3 moves forward, the second baffle 1 will be pushed open, thereby cleaning the impurities. During this process, the cleaning plug 3 will keep the top seat 9 in the pushed-out state according to its length. After the cleaning plug 3 disengages from the top seat 9, the insert plate 10 will be inserted back into the socket 12, and the clamp head 17 can be inserted back into the clamping slot 18. The second baffle 1 can be fixed, thereby achieving stable protection.

[0025] A baffle 7 is fixedly installed at the other end of the slide rod 5. The diameter of the baffle 7 is larger than the diameter of the slide rod 5. A first return spring 8 is sleeved on the slide rod 5 between the baffle 7 and the outer plate 4. The two ends of the first return spring 8 are fixedly connected to the side walls of the baffle 7 and the outer plate 4, respectively. The first return spring 8 can be used to reverse the movement of the slide rod 5, thereby ensuring the reset after the second baffle 1 is pushed open. The torque of the first return spring 8 is greater than the torque of the second spring. When the insert plate 10 is inserted into the socket 12, it can move the socket 12 upward slightly. When the latch 17 is inserted into the latch 18, the socket 12 is reset by the movement of the second return spring 14.

[0026] The plug plate 10 is connected through the outer plate 4. The plug plate 10 has a slot 18. The end of the plug plate 10 facing the socket 12 is connected to a bevel 11, which can be easily inserted into the socket 12.

[0027] A horizontal groove 6 is provided on the flushing pipe body 2, and a guide rod 15 is provided in the horizontal groove 6. The guide rod 15 can restrict the guide plate 16, and the guide plate 16 will move up and down along the guide rod 15.

[0028] A guide plate 16 is slidably connected to the guide rod 15. A second return spring 14 is sleeved on the guide rod 15 below the guide plate 16. The guide plate 16 is connected to the connecting seat 13. The guide plate 16 can be moved along the guide rod 15 by the second return spring 14.

[0029] One end of the connector 13 is connected to the socket 12, and the other end of the connector 13 is connected to the top seat 9. The top seat 9 is arc-shaped towards the end of the cleaning plug 3. The connection between the socket 12 and the top seat 9 can achieve linkage. When the top seat 9 is pushed, the socket 12 will move outward, thereby enabling the clip 17 to be pulled out of the slot 18, thus ensuring that the plug plate 10 can be separated from the socket 12.

[0030] The socket 12 is shaped like a square. A plug plate 10 is inserted into the socket 12. A latch 17 is provided at the top of the socket 12. The latch 17 is engaged in the latch 18. By engaging the latch 17 in the latch 18, the plug plate 10 can be restricted, thereby ensuring that the plug plate 10 will not come out of the socket 12 and the second baffle 1 will not be easily opened.

[0031] The working principle of this utility model is as follows: Water is injected into the flushing pipe body 2, and the water will eventually be discharged through the filter plate on the second baffle 1, thereby achieving flushing. After flushing is stopped, the cleaning plug 3 is pushed along the inner wall of the flushing pipe body 2 by the hydraulic component. During the movement of the cleaning plug 3, impurities can be scraped off. As the cleaning plug 3 moves forward, impurities will continue to be pushed. When the cleaning plug 3 moves to the position of the top seat 9, it will squeeze the top seat 9 out of the pipe. The top seat 9 will then drive the socket 12 to move outward. The latch 17 on the socket 12 can then be removed from the latch 18 of the insert plate 10. At this time, the insert plate 10 can be disengaged from the socket 12. As the cleaning plug 3 advances, impurities reach the position of the second baffle 1. With the feeding of the cleaning plug 3, the second baffle 1 is pushed open, and the impurities can be discharged from the pipe. Then, the cleaning plug 3 is controlled to reset. The second baffle 1 is reset by the action of the first reset spring 8, thereby blocking the pipe again. At this time, the insert plate 10 on the second baffle 1 will be inserted into the socket 12 again. With the reset of the cleaning plug 3, the top seat 9 will not be pushed. The socket 12 will be driven down by the action of the second reset spring 14, and the clamp head 17 can be locked into the clamp slot 18 again. The second baffle 1 can be stably restricted and will not easily dislodge and open.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
