[0033] 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, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0034] According to a specific embodiment of the present invention, Figs. 1-2 As shown, the present invention provides a desilting device for a drainage ditch in an underground tunnel. A sedimentation tank 200 is provided at intervals in a drainage ditch 100, and a desilting device is provided between two adjacent sedimentation tanks 200.

[0035] The desilting equipment includes:

[0036] The two scrapers 1 are rotatably arranged on the same rotating shaft 2 , and the two scrapers 1 are symmetrically arranged along the rotating shaft 2 .

[0037] The elastic member is arranged between the two scrapers 1 and is used to keep the two scrapers 1 in an outwardly expanded state at all times.

[0038] The balancing frame 6 is hinged on the rotating shaft 2 , with the hinge axis perpendicular to the extending direction of the rotating shaft 2 , and the balancing frame 6 is located on the backs of the two scrapers 1 .

[0039] The driving assembly is connected to the rotating shaft 2 and drives the scraper 1 to move along the drainage ditch 100 by driving the rotating shaft 2 to move.

[0040] In the dredging device, the elastic member keeps the two scrapers 1 in an open state, and the elastic member enables the two scrapers 1 to always adapt to the different widths of the drainage ditch 100, so that the silt in the drainage ditch 100 can be cleaned more efficiently. The balance frame 6 is arranged at the back of the two scrapers 1, so that the two scrapers 1 can be in a vertical state with a certain angle of backward inclination, which is more convenient for the scraper 1 to scrape the silt in the drainage ditch 100. The driving assembly drives the scraper 1 to move along the drainage ditch 100, so that the scraper 1 pushes the scraped silt into the drainage ditch 100. At this time, only the silt in the drainage ditch 100 needs to be cleaned, which greatly reduces the labor intensity of the dredging work and improves the work efficiency.

[0041] The elastic member is a torsion spring 3, the torsion spring 3 is sleeved on the rotating shaft 2, and the two elastic segments of the torsion spring 3 are connected to the two scrapers 1 respectively. In an embodiment of the present application, two torsion springs 3 are arranged between the two scrapers 1, so that the two scrapers 1 can be more evenly expanded under the action of the elastic force, so as to better adapt to the drainage ditch 100 of different widths after the two scrapers 1 are elastically expanded. In other embodiments of the present application, the elastic member can also be a common spring, and the two ends of the spring are connected to the two scrapers 1 respectively, and the spring is in a compressed state, which is used to enable the two scrapers 1 to always bear the outward expansion of the elastic force.

[0042] The edge of the two scrapers 1 close to the side wall of the drainage ditch 100 is rotationally provided with a pulley 4, and the pulley 4 rolls along the side wall of the drainage ditch 100. In an embodiment of the present application, two pulleys 4 are arranged on one side of the scraper 1 close to the side plate of the drainage ditch 100. The sliding arrangement can avoid the contact between the side edges of the scraper 1 and the side wall of the drainage ditch 100, so as to reduce the frictional resistance between the scraper 1 and the side wall of the drainage ditch 100, and facilitate the movement of the scraper 1 along the drainage ditch 100.

[0043] The bottom of the scraper 1 is provided with a sawtooth blade 5, which is used to shovel the silt at the bottom of the drainage ditch 100. In an embodiment of the present application, the sawtooth blade 5 can more efficiently shovel the silt at the bottom of the drainage ditch 100, and the end of the sawtooth blade 5 is serrated, which reduces the contact area with the bottom of the drainage ditch 100, and facilitates the smooth movement of the sawtooth blade 5 along the drainage ditch 100.

[0044] The balance frame 6 is a steel frame structure, and the bottom of the balance frame 6 is provided with a plurality of rollers. In an embodiment of the present application, the balance frame 6 of the steel frame structure is provided with four rollers, which are used to ensure that the balance frame 6 has a more stable state, so as to provide sufficient supporting force for the scraper 1.

[0045] The balance frame 6 is provided with an upper limiting block 8, and the upper limiting block 8 is in the same plane as the rotating shaft 2. The upper limiting block 8 is used to limit the upward turning angle of the two scrapers 1.

[0046] The lower limiting block 7 is arranged on the balance frame 6 and is in the same plane as the rotating shaft 2, and is used to limit the angle of the two scrapers 1 being turned downward.

[0047] In an embodiment of the present application, the upper limiting block 8 and the lower limiting block 7 are arranged to limit the rotating angle of the two scrapers 1 relative to the balance frame 6, so that the scrapers 1 are always in a vertical state with a certain angle of backward inclination, thereby avoiding the extreme state position of the two scrapers 1 being completely rotated to the horizontal state and the vertical state.

[0048] The driving assembly includes two front electric hoists 9, and the steel wire ropes of the two front electric hoists 9 are connected to the rotating shaft 2, and are used to pull the rotating shaft 2 to move forward. In an embodiment of the present application, the front electric hoists 9 are arranged near the position of the sedimentation tank 200, and the steel wire ropes of the two front electric hoists 9 are arranged to pull the rotating shaft 2 to move forward, so that the force acting on the two scrapers 1 is more uniform, thereby driving the two scrapers 1 to move forward stably to hang and drop the sludge in the drainage ditch 100 into the sedimentation tank 200.

[0049] The driving assembly further includes a rear electric hoist 10, and the steel wire rope of the rear electric hoist 10 is connected to the balance frame 6, and is used to pull the balance frame 6 to move backward. In an embodiment of the present application, the rear electric hoist 10 is arranged behind the balance frame 6, and is used to pull the balance frame 6 to move backward; and the front electric hoist 9 and the rear electric hoist 10 interact with each other to make the scrapers 1 reciprocate in the drainage ditch 100.

[0050] The present application further provides a method for dredging the drainage ditch 100 in the underground roadway, and the dredging method uses the dredging device for the drainage ditch 100 in the underground roadway according to claim 9, and the dredging method includes the following steps:

[0051] Step 1: start the front electric hoist 9 to pull the scrapers 1 to move toward the sedimentation tank 200 to scrape the sludge in the drainage ditch 100 into the sedimentation tank 200; in this process, under the limiting action of the lower limiting block 7, the scrapers 1 will not be turned downward excessively, so as to ensure that the scrapers 1 are always in a vertical state with a certain angle of backward inclination, and the scrapers 1 have a better sludge scraping state;

[0052] Step 2: when the scrapers 1 move to the position of the sedimentation tank 200, start the rear electric hoist 10 to pull the balance frame 6 backward to move the scrapers 1 away from the sedimentation tank 200 to reset the scrapers 1; in this process, under the action of the upper limiting block 8, the scrapers 1 will not be turned upward excessively to the horizontal state;

[0053] Step 3, repeating steps 1-2, the scraper 1 reciprocating in the gutter 100, to remove the silt in the gutter 100 in time to the sedimentation tank 200, to the sedimentation tank dilution silt, and using the dredging pump to remove the silt transport.
