Technical Field

[0001] The invention belongs to the technical field of tunnel desilting, and in particular relates to a desilting device for a drainage ditch in an underground tunnel. Background Art

[0002] In existing underground tunnels, drainage ditches are seriously accumulated with silt. The existing technology usually adopts manual dredging for regular cleaning, which results in a huge workload for the staff. Not only is the labor frequency low and the labor intensity high, but it also greatly affects the dredging efficiency of underground drainage ditches. If the dredging is not timely, the drainage ditches will be blocked. That is, the existing dredging method is extremely inefficient, affecting the working environment of the underground tunnels.

[0003] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

[0004] The object of the present invention is to provide an underground tunnel drainage ditch desilter to at least solve the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A silt remover for a drainage ditch in an underground tunnel, wherein a sedimentation tank is arranged at intervals in the drainage ditch, and a silt remover is arranged between two adjacent sedimentation tanks;

[0007] The silt remover comprises:

[0008] A crawler-driven vehicle, wherein crawler tracks are laid at the bottom of the drainage ditch along the extension direction of the drainage ditch, and the crawler-driven vehicle moves on the crawler tracks;

[0009] A sawtooth shovel blade, which is arranged at the front end of the crawler-driven vehicle, and which shovels up the silt in the drainage ditch when the crawler-driven vehicle moves forward;

[0010] The storage mechanism is arranged at the rear end of the crawler-driven vehicle. When the crawler-driven vehicle moves forward, the sludge accumulates in the storage mechanism, and after the displacement to the sedimentation tank position, the sludge is unloaded in the sedimentation tank.

[0011] As described above, in the underground tunnel drainage ditch cleaner, preferably, the front end of the crawler-driven vehicle is an inclined structure, and the inclined structure is transitionally connected with the serrated shovel blade.

[0012] As described above, in the underground tunnel drainage ditch desilter, preferably, both sides of the front end of the crawler-driven vehicle are provided with elastic guide mechanisms, and the elastic guide mechanisms at least include guide wheels, and the guide wheels are in contact with the side walls of the drainage ditch and roll along the side walls of the drainage ditch.

[0013] As described above, in the underground tunnel drainage ditch desilter, preferably, the elastic guide mechanism further comprises a guide rod, one end of which is hinged to the front end of the crawler drive vehicle, and the other end of which is rotatably provided with a guide wheel.

[0014] As described above, in the underground tunnel drainage ditch desilter, preferably, a torsion spring is provided between the guide rod and the crawler drive vehicle so that the guide rod can be elastically expanded toward the side wall of the drainage ditch.

[0015] As described above, in the underground tunnel drainage ditch desilter, preferably, the storage mechanism comprises a storage tank, and an opening is provided at the bottom of the storage tank.

[0016] As described above, in the underground tunnel drainage ditch desilter, preferably, the storage mechanism further comprises a pair of scissor plates hingedly arranged at the bottom of the storage tank, and the pair of scissor plates are sealed at the opening position when closed to each other.

[0019] As described above, the underground tunnel drainage ditch silt remover is preferably provided with a pair of blocks at the bottom of the drainage ditch in front of the sedimentation tank. When the crawler-driven vehicle moves forward to the block position, the block and one edge of the L-shaped scissor plate block each other, causing the pair of scissor plates to rotate outward to open the opening at the bottom of the storage tank.

[0020] Beneficial effects:

[0021] In the silt remover, when the crawler-driven vehicle moves forward in the drainage ditch along the crawler track, the serrated shovel blade at the front end shovels up the silt in the drainage ditch, and under the forward movement of the crawler-driven vehicle, the silt is transported to the storage mechanism at the rear end of the crawler-driven vehicle for temporary storage, which not only realizes the collection of silt in the drainage ditch, but also enables the silt at the front end of the crawler-driven vehicle to be cleaned, so as not to affect the forward movement of the crawler-driven vehicle; when the crawler-driven vehicle moves to the sedimentation tank, the storage mechanism unloads the stored silt into the sedimentation tank. At this time, it is only necessary to clean the silt in the drainage ditch at a fixed point, and water can be added to the sedimentation tank to dilute the silt, and a silt removal pump can be used to pump out and transport the silt; the silt remover greatly reduces the labor intensity of silt removal work and improves work efficiency.

[0022] When a pair of scissor plates are closed to each other, the opening position is blocked so that the storage tank can store sludge; when the crawler drive vehicle moves to the sedimentation tank position, the pair of scissor plates rotate and open to each other so that the opening at the bottom of the storage tank is opened toward the sedimentation tank, which makes it easier to unload the sludge temporarily stored in the storage tank into the sedimentation tank.

[0032] A crawler-driven vehicle 1 is provided with crawler tracks 7 at the bottom of the drainage ditch along the extension direction of the drainage ditch, and the crawler-driven vehicle 1 moves on the crawler tracks 7;

[0033] The sawtooth shovel blade 2 is arranged at the front end of the crawler-driven vehicle 1. When the crawler-driven vehicle 1 moves forward, the sawtooth shovel blade 2 shovels up the silt in the drainage ditch;

[0034] The storage mechanism is arranged at the rear end of the crawler-driven vehicle 1 . During the forward movement of the crawler-driven vehicle 1 , the sludge accumulates in the storage mechanism, and after being moved to the position of the sedimentation tank 10 , the sludge is unloaded in the sedimentation tank 10 .

[0035] In the silt remover, when the crawler-driven vehicle 1 moves forward along the crawler track 7 in the drainage ditch, the sawtooth shovel blade 2 at the front end shovels up the silt in the drainage ditch, and under the forward movement of the crawler-driven vehicle 1, the silt is transported to the storage mechanism at the rear end of the crawler-driven vehicle 1 for temporary storage, which not only realizes the collection of silt in the drainage ditch, but also makes the silt at the front end of the crawler-driven vehicle 1 be cleaned, so as not to affect the forward movement of the crawler-driven vehicle 1; when the crawler-driven vehicle 1 moves to the sedimentation tank 10, the storage mechanism unloads the stored silt into the sedimentation tank 10. At this time, it is only necessary to clean the silt in the drainage ditch at a fixed point, and water can be added to the sedimentation tank 10 to dilute the silt, and the silt can be pumped out and transported by a silt removal pump; the silt remover greatly reduces the labor intensity of silt removal work and improves work efficiency.

[0036] After completing one drainage ditch dredging operation, the dredging device can be manually transferred to the starting point of the drainage ditch so that the dredging device can repeat the dredging operation on the drainage ditch.

[0037] The front end of the crawler-driven vehicle 1 is an inclined structure, and the inclined structure is transitionally connected to the sawtooth blade 2. In one embodiment of the present application, an inclined structure is provided at the front end of the crawler-driven vehicle 1, so that during the forward movement of the crawler-driven vehicle 1, the sludge is gradually transferred to the rear end of the crawler-driven vehicle 1 through the inclined structure, so as to facilitate the transportation and storage of the sludge.

[0038] Both sides of the front end of the crawler-driven vehicle 1 are provided with elastic guide mechanisms 3, and the elastic guide mechanisms 3 at least include guide wheels 32, and the guide wheels 32 are in contact with the side walls of the drainage ditch and roll along the side walls of the drainage ditch. In one embodiment of the present application, an elastic guide mechanism 3 is provided at the front end of the crawler-driven vehicle 1, so that the crawler-driven vehicle 1 can realize the transport movement in the drainage ditch with a certain curvature, so that the silt remover can adapt to drainage ditches with different curvatures.

[0039] The elastic guide mechanism 3 further includes a guide rod 31, one end of which is hinged to the front end of the crawler-driven vehicle 1, and the other end is rotatably provided with a guide wheel 32. In one embodiment of the present application, the guide rod 31 serves as an extension of the guide wheel 32, so that the crawler-driven vehicle 1 can adapt to drainage ditches of different widths.

[0040] A torsion spring is provided between the guide rod 31 and the crawler drive vehicle 1 to enable the guide rod 31 to be elastically extended toward the side wall of the gutter. In one embodiment of the present application, a torsion spring is provided to enable the guide rod 31 to be elastically in contact with the side wall of the gutter, so that the crawler drive vehicle 1 can better achieve smooth steering in gutterings of different widths.

[0041] The storage mechanism comprises a storage tank 4 , and an opening is arranged at the bottom of the storage tank 4 . In one embodiment of the present application, the storage tank 4 is convenient for temporarily storing sludge, and the opening at the bottom of the storage tank 4 is convenient for unloading the sludge into the sedimentation tank 10 .

[0042] The storage mechanism further includes a pair of scissor plates 5 hingedly arranged at the bottom of the storage tank 4, and the pair of scissor plates 5 are sealed at the opening position when they are closed. In one embodiment of the present application, when the pair of scissor plates 5 are closed, the opening position is blocked so that the storage tank 4 plays the role of storing sludge; when the crawler drive vehicle 1 moves to the sedimentation tank 10, the pair of scissor plates 5 rotate and open to each other, so that the opening at the bottom of the storage tank 4 is opened toward the sedimentation tank 10, so that the sludge temporarily stored in the storage tank 4 is unloaded into the sedimentation tank 10.

[0043] The scissor plate 5 is an L-shaped structure. The inflection point of the L-shaped scissor plate 5 is hinged to the bottom of the storage tank 4. In one embodiment of the present application, by pushing one side of the L-shaped scissor plate 5, the scissor plate 5 can be rotated, thereby controlling the closing and opening process of the opening.

[0044] A pair of blocks 6 are provided at the bottom of the drainage ditch in front of the sedimentation tank 10. When the track-driven vehicle 1 moves forward to the position of the block 6, the block 6 and one edge of the L-shaped scissor plate 5 are mutually blocked, so that the pair of scissor plates 5 rotate outward to open the opening at the bottom of the storage tank 4. In one embodiment of the present application, when the block 6 and one edge of the L-shaped scissor plate 5 are mutually blocked and interfered, as the track-driven vehicle 1 moves forward, the L-shaped scissor plate 5 rotates around its hinge point, so that the opening at the bottom of the storage tank 4 is opened, so that the sludge in the storage tank 4 is unloaded into the sedimentation tank 10, and then water is added to the sedimentation tank 10 to dilute the sludge, and then the diluted sludge is pumped away by the dredging pump to complete the dredging work in the laneway drainage ditch, thereby greatly improving the dredging efficiency of the laneway drainage ditch.
