Description

Technical Field

[0001] This invention belongs to the field of tunnel dredging technology, specifically relating to a dredging device for underground tunnel drainage ditches. Background Technology

[0002] In existing underground roadways, drainage ditches are severely silted up. Current technology usually involves manual dredging for regular cleaning, which results in a huge workload for workers. Not only is the work frequency low and the labor intensity high, but it also greatly affects the dredging efficiency of underground drainage ditches. If dredging is not done in time, it will cause blockage of the drainage ditches. In other words, the current dredging method is extremely inefficient and affects the working environment of underground roadways.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a dredging device for underground roadway drainage ditches, so as to at least solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sludge removal device for underground roadway drainage ditches includes a sedimentation tank set at intervals in the drainage ditch, and a sludge removal device set between two adjacent sedimentation tanks.

[0007] The dredging device includes:

[0008] A tracked vehicle has tracked tracks laid at the bottom of the drainage ditch along its extension direction, and the tracked vehicle moves on the tracked tracks.

[0009] A serrated shovel blade is installed at the front end of the tracked vehicle. As the tracked vehicle moves forward, the serrated shovel blade scoops up the silt in the drainage ditch.

[0010] The storage mechanism is located at the rear end of the tracked vehicle. During the forward movement of the tracked vehicle, sludge accumulates in the storage mechanism and is unloaded into the sedimentation tank after the vehicle moves to the sedimentation tank position.

[0011] In the underground roadway drainage ditch dredging device described above, preferably, the front end of the tracked drive vehicle is an inclined structure, and the inclined structure is transitionally connected to the sawtooth shovel.

[0012] In the underground roadway drainage ditch dredging device described above, preferably, both sides of the front end of the tracked vehicle are provided with elastic guide mechanisms. The elastic guide mechanism includes at least a guide wheel, which contacts the side wall of the drainage ditch and rolls against the side wall of the drainage ditch.

[0013] The underground roadway ditch dredging device has the advantages that the elastic guide mechanism further comprises a guide rod, one end of the guide rod is hingedly connected to the front end of the crawler driving vehicle, and the other end of the guide rod is rotatably provided with a guide wheel.

[0014] The underground roadway ditch dredging device has the advantages that a torsion spring is arranged between the guide rod and the crawler driving vehicle, so that the guide rod is elastically expanded towards the side wall of the ditch.

[0015] The underground roadway ditch dredging device has the advantages that the storage mechanism is soft cloth, and the soft cloth is used for temporarily storing the sludge.

[0016] The underground roadway ditch dredging device has the advantages that the bottom of the soft cloth is provided with a wear-resistant layer.

[0017] The underground roadway ditch dredging device has the advantages that the storage mechanism comprises a storage tank, and the storage tank is arranged at the rear of the crawler driving vehicle.

[0018] The underground roadway ditch dredging device has the advantages that the bottom of the storage tank is provided with an opening, a sealing plate is hingedly arranged at the opening position, and the sealing plate is downwardly rotated to open the opening.

[0019] The underground roadway ditch dredging device has the advantages that the lower end of the sealing plate is rotatably provided with a pulley.

[0020] Beneficial effects:

[0021] In the dredging device, the sawtooth blade at the front end scoops up the sludge in the ditch during the movement of the crawler driving vehicle along the track in the ditch, and the sludge is transported to the storage mechanism at the rear end of the crawler driving vehicle under the action of the movement of the crawler driving vehicle, so as to temporarily store the sludge, realize the collection of the sludge in the ditch, and clean the sludge at the front end of the crawler driving vehicle, so as to not affect the movement of the crawler driving vehicle; when the crawler driving vehicle moves to the sedimentation tank position, the storage mechanism unloads the stored sludge into the sedimentation tank. At this time, only the sludge in the ditch needs to be cleaned, water can be added to the sedimentation tank to dilute the sludge, and the sludge can be pumped out and transported; the dredging device greatly reduces the labor intensity of the dredging work and improves the work efficiency.

[0022] The crawler driving vehicle is more convenient to drag the soft cloth to move forward, and when the crawler driving vehicle moves to the sedimentation tank position, 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 caterpillar vehicle moves to the sedimentation tank position, the pulley loses support and swings downward with the sealing plate into the sedimentation tank to open the opening at the bottom of the storage tank, allowing the sludge in the storage tank to naturally unload into the sedimentation tank.

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

[0032] According to a specific embodiment of the present application, as shown in Figs. 1-3 The present application provides a device for dredging a drainage ditch in a mine roadway, wherein a sedimentation tank 10 is arranged in the drainage ditch at a distance, and a dredging device is arranged between two adjacent sedimentation tanks 10.

[0033] The dredging device comprises:

[0034] A caterpillar drive vehicle 1 is arranged on the bottom of the drainage ditch along the extension direction of the drainage ditch, and the caterpillar drive vehicle 1 moves on a caterpillar track 8.

[0035] A sawtooth blade 2 is arranged at the front end of the caterpillar drive vehicle 1, and the sawtooth blade 2 scoops up the sludge 20 in the drainage ditch during the forward movement of the caterpillar drive vehicle 1.

[0036] A storage mechanism is arranged at the rear end of the caterpillar drive vehicle 1, and the sludge 20 is accumulated in the storage mechanism during the forward movement of the caterpillar drive vehicle 1, and the sludge 20 is unloaded into the sedimentation tank 10 after being displaced to the position of the sedimentation tank 10.

[0037] In the dredging device, the sawtooth blade 2 at the front end scoops up the sludge 20 in the drainage ditch during the forward movement of the caterpillar drive vehicle 1 along the caterpillar track 8 in the drainage ditch, and the sludge 20 is transported to the storage mechanism at the rear end of the caterpillar drive vehicle 1 under the action of the forward movement of the caterpillar drive vehicle 1, and is temporarily stored in the storage mechanism. Not only is the sludge 20 in the drainage ditch collected, but also the sludge 20 at the front end of the caterpillar drive vehicle 1 is cleaned, so that the forward movement of the caterpillar drive vehicle 1 is not affected. When the caterpillar drive vehicle 1 is moved to the position of the sedimentation tank 10, the sludge 20 stored in the storage mechanism is unloaded into the sedimentation tank 10. At this time, only the sludge 20 in the drainage ditch needs to be cleaned, 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. The dredging device greatly reduces the labor intensity of dredging work and improves the work efficiency.

[0038] After completing the dredging of the drainage ditch once, the dredging device can be manually turned around to reciprocate along the drainage ditch. The dredging device can also be manually transported to the starting position of the drainage ditch to repeatedly dredge the drainage ditch.

[0039] The front end of the caterpillar drive vehicle 1 is an inclined structure, and the inclined structure is transitionally connected with the sawtooth blade 2. In an embodiment of the present application, the inclined structure is arranged at the front end of the caterpillar drive vehicle 1, so that the sludge 20 is gradually transitionally transported to the rear end of the caterpillar drive vehicle 1 through the inclined structure during the forward movement of the caterpillar drive vehicle 1, facilitating the transportation and storage of the sludge 20.

[0040] The front end of the track drive vehicle 1 is provided with an elastic guide mechanism 3 on both sides, which at least comprises a guide wheel 32, which is in contact with the side wall of the drainage ditch and rolls along the side wall. In an embodiment of the present application, the elastic guide mechanism 3 is arranged at the front end of the track drive vehicle 1, which facilitates the track drive vehicle 1 to realize the transfer movement in the drainage ditch with a certain bending radius, so that the dredging device can adapt to the drainage ditch with different bending radii.

[0041] The elastic guide mechanism 3 further comprises a guide rod 31, one end of which is hinged to the front end of the track drive vehicle 1, and the other end is rotatably provided with the guide wheel 32. In an embodiment of the present application, the guide rod 31 is an extension of the guide wheel 32, so that the track drive vehicle 1 can adapt to the drainage ditch with different widths.

[0042] A torsional spring is arranged between the guide rod 31 and the track drive vehicle 1, so that the guide rod 31 is elastically expanded towards the side wall of the drainage ditch. In an embodiment of the present application, the torsional spring is arranged to enable the guide rod 31 to elastically contact the side wall of the drainage ditch, so that the track drive vehicle 1 can better realize smooth turning in the drainage ditch with different widths.

[0043] The storage mechanism is a soft cloth 4, which is used for temporarily storing the sludge 20. In an embodiment of the present application, the track drive vehicle 1 is more convenient to drag the soft cloth 4 to move forward, and when the track drive vehicle 1 moves to the position of the settling tank 10, the soft cloth 4 naturally falls into the settling tank 10, so that the sludge 20 on the soft cloth 4 falls into the settling tank 10, thereby facilitating the unloading operation of the sludge 20.

[0044] The bottom of the soft cloth 4 is provided with a wear-resistant layer. In an 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 to increase the service life of the soft cloth 4.

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

[0046] The bottom of the storage tank 5 is provided with an opening, and a sealing plate 5 is hingedly arranged at the opening position, which is downwardly rotated to open the opening. In an embodiment of the present application, when the track drive vehicle 1 moves to the position of the settling tank 10, the sealing plate 5 is downwardly rotated to open the opening towards the settling tank 10, so that the sludge 20 in the storage tank 5 is unloaded into the settling tank 10.

[0047] The lower end of the sealing plate 5 is rotatably provided with a pulley 7. In an embodiment of the present application, when the caterpillar drive vehicle 1 moves to the position of the sedimentation tank 10, the pulley 7 loses support and swings downward together with the sealing plate 5 toward the sedimentation tank 10 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 can be understood that the above description is only exemplary, and the embodiments of the present application are not limited thereto.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application is within the scope of the claims of the present application.
