Description

Technical Field

[0001] The invention relates to the technical field of tunnel excavation equipment, and in particular to a stagnation dredging device and a use method thereof. Background Art

[0002] During the shield construction process, due to the complexity and changeability of the strata, different geology will bring different construction problems to the equipment construction. For example, in the pebble stratum, there is a problem of pebbles accumulating and blocking the slag outlet. The clogging problem can be solved by using a screw machine in conjunction with the slurry outlet pipe, but its effect is limited. If the situation is serious, the warehouse needs to be opened for treatment, which will have a great impact on equipment safety, economic benefits, and project progress. For stones that are too large, slag is usually discharged through a slurry outlet pipe or a screw machine combined with a crusher for comprehensive treatment.

[0003] For example, the patent with publication number CN105065007A discloses a shield machine mud-water circulation and stone crushing system, including a slurry inlet pipe, an air cushion cabin, a discharge pipe, a mud pipeline crusher, a slurry pump and a slurry discharge pipe which are connected in series in sequence through pipelines; the discharge pipe is used to transport the mud and sand and gravel in the air cushion cabin to the mud pipeline crusher, the mud pipeline crusher crushes the stones from the air cushion cabin, and the crushed materials are discharged to the outside of the system along with the mud through the slurry discharge pump and the slurry discharge pipe; and the mud pipeline crusher is a closed jaw crusher comprising a sealing gasket, a frame and a movable jaw assembly, and the interior of the crusher can seal mud fluid with a pressure of more than 0.5MPa.

[0004] In the above-mentioned mud-water circulation and stone crushing system, a mud pipeline crusher is arranged at the front end of the slurry discharge pump to crush the mud and stones entering the slurry discharge pump. However, since the material discharged from the discharge pipe is a mixture of mud and stones, the mud pipeline crusher cannot accurately crush the stones, and the mud pipeline crusher is prone to doing useless work. Continuous operation of the mud pipeline crusher will cause energy waste. Summary of the invention

[0005] The present invention provides a device for clearing and unblocking wastewater and a method for using the device, which solves the problem in the prior art that it is impossible to accurately crush the rocks blocking the warehouse.

[0006] The technical solution of the present invention is achieved in this way: A device for clearing and unblocking a stagnation of drainage comprises a connecting base and a crushing component, wherein a rotating mechanism is provided on the connecting base, and a valve is connected to the rotating mechanism; when the device is in use, the head of the crushing component passes through the valve and the rotating mechanism, and the head of the crushing component extends out of the connecting base. When a silo is blocked, the valve is opened, and the head of the crushing component is extended through the valve to the position of the stone, and the angle of the crushing component is adjusted by the rotating mechanism so that the crushing component can be aligned with the stone, so that the crushing component can accurately crush the stone, thereby avoiding the situation where the device for clearing and unblocking a stagnation of drainage does useless work and saving energy.

[0007] The rotating mechanism includes a first rotating seat, a rotating member, and a second rotating seat. The first rotating seat is connected to the connecting base, and the second rotating seat is detachably connected to the first connecting seat. The first rotating seat and the second rotating seat are provided with relatively arranged limiting structures. The rotating member includes a spherical rotating part, and the spherical rotating part is rotatably matched with the limiting structure. The first rotating seat is installed on the connecting base through a fixing bolt, and the second rotating seat is connected to the first rotating seat through a fixing bolt. The limiting structures on the first rotating seat and the second rotating seat limit the spherical rotating part of the rotating member, so that the rotating member can only rotate around the center of the spherical rotating part and cannot translate; the rotation of the spherical rotating part drives the head of the crushing assembly to swing, thereby realizing the adjustment of the direction of the head of the crushing assembly.

[0008] A sealing structure is provided between the first rotating seat and the second rotating seat, between the first rotating seat and the rotating member, and between the second rotating seat and the rotating member.

The flange connection part is connected to the valve through a fixing bolt, and the valve is used to control the opening and closing of the through hole. When the device is in use, the valve opens and the head of the crushing component passes through the through hole. After the device is used, the crushing component is withdrawn from the through hole, and the valve is closed. At this time, the through hole is closed, and the installation of the device on the shield machine does not affect the normal use of the shield machine.

[0010] The valve is connected with a sliding seal assembly, the sliding seal assembly and the rotating member are respectively located at both ends of the valve, and the sliding seal assembly cooperates with the head of the crushing assembly in a sliding seal. After the crushing assembly is connected to the valve, the sliding seal assembly seals the gap between the head of the crushing assembly and the valve to prevent mud from passing through the through hole and the valve channel, thereby ensuring water and soil pressure.

[0011] The sliding seal assembly includes a sealing cylinder, the end of which is connected to the valve, and a plurality of sealing rings are arranged on the inner wall of the sealing cylinder, and the sealing rings are slidably matched with the head of the crushing assembly. When the crushing assembly is crushing stones, the head of the crushing assembly will move forward, and at this time, the sealing ring ensures the sealing of the gap between the head of the crushing assembly and the valve during the movement of the crushing assembly.

[0012] The connecting base is provided with a driving assembly for driving the rotating mechanism to move. The driving assembly can adjust and support the rotation angle of the rotating member. Before the stone is crushed, the driving assembly adjusts the rotation angle of the rotating member. During the stone crushing process, the driving assembly keeps the crushing assembly in a stable direction, ensuring that the crushing assembly can crush the stone stably, avoiding the situation where the crushing assembly head and the stone slip, and ensuring the stone crushing efficiency.

[0013] The drive assembly includes a plurality of telescopic oil cylinders, which are evenly arranged on the outside of the rotating part. One end of the telescopic oil cylinder is movably connected to the connecting base, and the other end of the telescopic oil cylinder is movably connected to the rotating part.

The crushing assembly is installed when in use and can be removed at any time when not in use for easy inspection and maintenance.

[0014] In S3, the rotation member of the rotating mechanism is driven to rotate by the extension and retraction of each telescopic oil cylinder in the driving assembly, and the direction of the crushing assembly is adjusted by the rotation of the rotating member.
