[0002] In the existing underground tunnels, the drainage ditches are seriously accumulated with silt. The existing technology usually adopts manual dredging for regular cleaning, which leads to 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 the 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 desilting device 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 desilting device for drainage ditches in underground tunnels, wherein a sedimentation tank is arranged at intervals in the drainage ditch, and a desilting device is arranged between two adjacent sedimentation tanks;

[0007] The desilting device 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 desilting device, preferably, the front end of the crawler-driven vehicle is an inclined structure, and the inclined structure is transitionally connected to the serrated shovel blade.

[0012] As described above, in the underground tunnel drainage ditch desilting device, preferably, elastic guide mechanisms are provided on both sides of the front end of the crawler-driven vehicle, 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] In the underground tunnel drainage ditch desilting device as described above, preferably, the elastic guide mechanism also includes 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 desilting device, 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] In the underground tunnel drainage ditch desilting device as described above, preferably, the storage mechanism is a soft cloth, and the soft cloth is used to temporarily store silt.

[0019] As described above, in the underground tunnel drainage ditch desilting device, preferably, a pulley is rotatably provided at the lower end of the sealing plate.

[0020] Beneficial effects:

[0021] In the dredging device, when the crawler-driven vehicle moves forward in the drainage ditch along the crawler track, the serrated shovel 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 dredging pump can be used to pump out and transport the silt; the dredging device greatly reduces the labor intensity of dredging work and improves work efficiency.

[0022] The crawler-driven vehicle is more convenient for dragging the soft cloth forward, and when the crawler-driven vehicle moves to the sedimentation tank, the soft cloth naturally falls into the sedimentation tank, so that the sludge on the soft cloth falls into the sedimentation tank, thereby facilitating the unloading operation of the sludge.

[0023] When the crawler-driven vehicle moves to the sedimentation tank, the pulley loses support and swings downward into the sedimentation tank together with the sealing plate to open the opening at the bottom of the storage tank, so that the sludge in the storage tank is naturally unloaded into the sedimentation tank.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0032] According to a specific embodiment of the present invention, Figure 1-3 As shown, the present invention provides a desilting device for a drainage ditch in an underground tunnel, wherein a sedimentation tank 10 is arranged at intervals in the drainage ditch, and a desilting device is arranged between two adjacent sedimentation tanks 10;

[0033] The desilting equipment includes:

[0034] A crawler-driven vehicle 1 is provided with crawler tracks 8 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 8;

[0035] A sawtooth shovel blade 2, which 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 scoops up the silt 20 in the drainage ditch;

[0036] 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 20 is accumulated in the storage mechanism, and after being moved to the position of the sedimentation tank 10 , the sludge 20 is unloaded in the sedimentation tank 10 .

[0037] In the dredging device, when the crawler-driven vehicle 1 moves forward along the crawler track 8 in the drainage ditch, the sawtooth shovel blade 2 at the front end shovels up the sludge 20 in the drainage ditch, and under the forward movement of the crawler-driven vehicle 1, the sludge 20 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 the sludge 20 in the drainage ditch, but also enables the sludge 20 at the front end of the crawler-driven vehicle 1 to 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 sludge 20 into the sedimentation tank 10. At this time, it is only necessary to clean the sludge 20 in the drainage ditch at a fixed point, and water can be added to the sedimentation tank 10 to dilute the sludge 20, and the sludge 20 can be pumped out and transported by a dredging pump; the dredging device greatly reduces the labor intensity of dredging work and improves work efficiency.

[0038] After completing one drainage ditch desilting operation, the desilting device can be manually turned around to make the desilting device reciprocate along the drainage ditch, or the desilting device can be manually transferred to the starting point of the drainage ditch to repeat the desilting operation on the drainage ditch.

[0039] 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 the sludge 20 is gradually transferred to the rear end of the crawler-driven vehicle 1 through the inclined structure during the forward advancement of the crawler-driven vehicle 1, so as to facilitate the transportation and storage of the sludge 20.

[0040] 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 transfer movement in the drainage ditch with a certain curvature, so that the silt removal device can adapt to drainage ditches with different curvatures.

[0041] 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 of which 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.

[0042] 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.

[0043] The storage mechanism is a soft cloth 4, which is used to temporarily store the sludge 20. In one embodiment of the present application, the track-driven vehicle 1 is more convenient to drag the soft cloth 4 forward, and when the track-driven vehicle 1 moves to the sedimentation tank 10, the soft cloth 4 naturally falls into the sedimentation tank 10, so that the sludge 20 on the soft cloth 4 falls into the sedimentation tank 10, thereby facilitating the unloading operation of the sludge 20.

[0044] A wear-resistant layer is provided at the bottom of the soft cloth 4. In one embodiment of the present application, the wear-resistant layer can be a PE film or a PTFE film, so that the soft cloth 4 has better wear resistance and increases the service life of the soft cloth 4.

[0045] The storage mechanism includes a storage tank 5, which is arranged at the rear of the track-driven vehicle 1. In one embodiment of the present application, the storage tank 5 is fixed at the rear of the track-driven vehicle 1, and the storage tank 5 is arranged in a square structure for storing the sludge 20 scooped up by the track-driven vehicle 1.

[0046] The bottom of the storage tank 5 is provided with an opening, and a sealing plate 5 is hingedly provided at the opening position, and the sealing plate 5 is rotated downward to open the opening. In one embodiment of the present application, when the crawler-driven vehicle 1 moves to the sedimentation tank 10 position, the sealing plate 5 is rotated downward to open the opening toward the sedimentation tank 10, so that the sludge 20 in the storage tank 5 is unloaded and re-discharged into the sedimentation tank 10.

[0047] The lower end of the sealing plate 5 is rotatably provided with a pulley 7. In one embodiment of the present application, when the crawler-driven vehicle 1 moves to the sedimentation tank 10, the pulley 7 loses support and swings downward toward the sedimentation tank 10 together with the sealing plate 5 to open the opening at the bottom of the storage tank 5, so that the sludge 20 in the storage tank 5 is naturally unloaded into the sedimentation tank 10.

[0048] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.
