Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel drainage, in particular to a tunnel longitudinal drainage pipeline dredging device. BACKGROUND

[0002] Tunnel waterproofing and drainage refers to the waterproofing and drainage measures taken to ensure that the tunnel building will not be damaged by seepage water, endangering driving safety, corroding equipment in the tunnel, and reducing the service life of the structure. After the tunnel is built, the original water system balance of the mountain is destroyed, and the tunnel becomes a channel for underground water to gather near the mountain. These underground water is rich in many minerals and other trace elements. After the underground water flows through the tunnel drainage pipeline for a long time, a large amount of solid crystalline substances will be deposited or condensed in the drainage pipeline. If these crystalline substances are not treated, they will seriously affect the drainage effect, and thus threaten the structure of the tunnel and affect the driving safety of the tunnel.

[0003] The existing treatment method generally uses cleaning agents that can dissolve crystalline substances to dredge the pipeline. In the pouring process, the staff can also insert a long rod into the pipeline to crush the crystalline substances. This method is simple and fast to operate, but the cleaning agent can dissolve the crystalline substances to a certain extent, which will erode the mountain. The existing tunnel drainage pipeline directly discharges water flow into the mountain depression outside, which can easily cause the structure of the mountain to be affected by the cleaning agent, and also pollute the surrounding ecological environment. In view of this, the present application provides a tunnel longitudinal drainage pipeline dredging device. SUMMARY

The rear end of the first guide groove 36 and the second guide groove 37 is provided with ball grooves 38 which are slidingly matched with the sliding ball 35. The front surface of the first guide groove 36 and the second guide groove 37 is wavy and annular in structure and centrally symmetrically arranged.

[0041] Working principle: The worker can place the device at the opening end of the tunnel longitudinal drainage pipe, and make the dredging mechanism 4 of the device extend into the pipeline. Then the worker can twist the hand wheel 45 to make the threaded rod 40 move downward along the threaded connection direction with the fixed seat 1, and the sliding seat 39 will also move downward. At the same time, the connecting rod 43 rotatingly connected on the sliding seat 39 will also move downward, because the lower end of the connecting rod 43 is rotatingly connected with the extrusion plate 42 which cannot move downward, so the connecting rod 43 can only deflect downward within the end point of the position rotatingly connected with the extrusion plate 42. Then the extrusion plate 42 can translate away from the fixed seat 1, and the multiple anti-skid strips 44 on the outer wall of the extrusion plate 42 can be extruded with the inner wall of the drainage pipeline to form a fixed effect. At this time, the mutual fixation of the device and the drainage pipeline is completed, and the opening end position of the drainage pipeline belongs to a relatively convenient cleaning area, so there will be no dredging dead angle due to the existence of the fixed seat 1.

[0042] During the process of extending the rotating shaft 5 into the drainage pipeline, the worker can connect multiple rotating shafts 5 together through the plug-in cooperation of the plug rod 10 and the rod slot 11, and the clamping cooperation of the clamping block 12 and the clamping slot 13. Two connected rotating shafts 5 will not separate without external pulling force. It should be noted that the structures of the remaining rotating shafts 5 in the device are the same except the first and the last two rotating shafts 5. The front end of the second spiral groove 15 on the first rotating shaft 5 and the rear end of the first spiral groove 14 on the last rotating shaft 5 are both open design. After the rotating shaft 5 is connected with other rotating shafts 5, the first spiral groove 14 and the second spiral groove 15 at the intersection position of the two rotating shafts 5 can be connected with each other and slidingly cooperate with the guide block 17. The rear end of the first spiral groove 14 on the first rotating shaft 5 and the front end of the second spiral groove 15 on the last rotating shaft 5 are the same. The front end of the second spiral groove 15 on the first rotating shaft 5 and the rear end of the first spiral groove 14 on the last rotating shaft 5 are the same. The front end of the second spiral groove 15 on the first rotating shaft 5 and the rear end of the first spiral groove 14 on the last rotating shaft 5 are the same. The closed structure is set to prevent the moving seat 6 and the rotating disc 8 from being out of the range of the rotating shaft 5 during the work of the device, and to reduce the operation difficulty of the device.

[0043] After the shaft 5 is connected, the motor 3 can drive the shaft 5 to rotate. The motor 3 is fixed on the bottom of the fixed seat 1, and is not coaxially fixed with the fixed seat 1. Therefore, the rotation of the motor 3 output end will not cause the rotation of the fixed seat 1 and the motor 3 under the action of friction. The moving seat 6 is also the same, because it is not coaxially arranged with the shaft 5, and the multiple shovel plates 7 on the outer wall are in sliding contact with the inner wall of the drainage pipeline. Therefore, the rotation of the shaft 5 will cause the moving seat 6 to move forward under the extrusion of the first spiral groove 14 and the second spiral groove 15. The moving seat 6 is also the same, because it is not coaxially arranged with the shaft 5, and the multiple shovel plates 7 on the outer wall are in sliding contact with the inner wall of the drainage pipeline. Therefore, the rotation of the shaft 5 will cause the moving seat 6 to move forward under the extrusion of the first spiral groove 14 and the second spiral groove 15.

[0044] On the other hand, the rotation of the shaft 5 will also drive the rotating disc 8 to rotate through the sliding connection relationship between the limiting block 21 and the limiting groove 22. The limiting groove 22 is relatively narrow, and the guide block 17 is a hemispherical structure, so it will not affect the extrusion of the two spiral grooves on the guide block 17. The rotating disc 8 is eccentrically connected with the moving seat 6 through the rotating rod 18 and the rotating groove 19, so its rotation will not affect the moving seat 6. The hostile broken blade 9 on the rotating disc 8 will also preliminarily crush the scale inside the drainage pipeline and break the crystalline substances in the middle of the drainage pipeline. These crystalline substances are far away from the inner wall of the drainage pipeline and are newly condensed, so their texture is softer than that of the crystalline substances at the edge of the drainage pipeline. They can be crushed by simple drilling. The stubborn crystalline substances at the edge position are cleaned by the horizontally arranged drill bit 27. These drill bits 27 will rotate with the rotating disc 8 during the forward movement of the moving seat 6 and the rotating disc 8. The rotation axis is not only the shaft 5 and the shaft groove 16, but also the disc 23. In this way, the bevel gear 25 at the inner end will always rotate under the action of the tooth groove 24. The bevel gear 25 drives the drill bit 27 to rotate through the multi-section telescopic rod 26. The sleeve rod near the drill bit 27 is a cylinder and is coaxial with the bevel gear 25. The other slidable extension rods are elliptical cylinders. The slots on each rod for the other extension rods are also elliptical cylinders. This design allows the multi-section telescopic rod 26 to have telescopic function and drive the drill bit 27 to rotate;

[0045] With the rotation of the multi-section telescopic rod 26 and the bevel gear 25, the movable plates 30 on them will also rotate synchronously, the movable plates close to the disc 23 will not move away from the disc 23 under the restriction of the slide plates 31 and the ring grooves 32, but will make a rotating movement with the center of the shaft of the disc 23 as the center, and the movable plates 30 away from the disc 23 will make a rotating movement while moving in and out under the sliding cooperation of the slide plates and the corresponding guide grooves, because the lengths of the first slide plate 33 and the second slide plate 34 are different, and the slide balls 35 are connected to the ends of the two slide plates, the position of the slide ball 35 on the second slide plate 34 corresponds to the position of the slide ball 35 on the first slide plate 33, and the slide ball 35 on the first slide plate 33 is located behind the slide ball 35 on the second slide plate 34, so even if there is a position of intersection between the two guide grooves, the two slide plates and the slide balls 35 thereon will not have the problem of stringing, but will only move in the corresponding guide grooves, under the guidance of the wave-shaped ring structure of the guide grooves, the multi-section telescopic rod 26 will continuously stretch and shrink, at the same time, the drill bit 27 will be pushed towards the inner wall of the drain pipe, in addition to the rotation of the drill bit 27 and the second breaking blade 28 and the plurality of crushing heads 29 arranged thereon for scraping off the crystalline substances, the drill bit 27 will sequentially and gradually break and crush the crystalline substances on the inner wall of the drain pipe in the process of approaching the inner wall of the drain pipe, and the portions of the two guide grooves close to the edge positions of the moving seat 6 are complementary, and the two guide grooves are coaxial with the moving seat 6, so there will be no cleaning dead angle.

[0046] During the occurrence of the above-mentioned actions, the guide block 17 will reciprocate and alternately correspond to the plurality of first spiral grooves 14 and the plurality of second spiral grooves 15, when it corresponds to the first spiral grooves 14, the rotating speed of the rotating disc 8 will not change, but the forward movement speed of the moving seat 6 will decrease, during which the stubborn crystalline substances on the inner wall of the drain pipe are crushed and destroyed to facilitate the complete scraping of the shovel plate 7 later, when the guide block 17 corresponds to the second spiral grooves 15, the opposite is true, which is to make the plurality of drill bits 27 quickly move to the next area of the inner wall of the drain pipe, reduce the overlapping part of the cleaning area of the two drill bits 27, and help to improve the cleaning speed.

[0047] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features thereof; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
