Description

Technical Field

[0001] This utility model relates to the field of coal mining dust control technology, specifically a dust control interface device for hydraulic supports in coal mining faces. Background Technology

[0002] Hydraulic supports for coal mining are essential equipment used in the coal mining process. They are primarily used to ensure the safe operation of coal mining operations and serve as a protective device to safeguard workers and prevent damage to mining equipment. Because coal mining generates a large amount of dust, dustproof interfaces or dust covers are typically installed around the shut-off valves on the hydraulic supports to prevent dust from clogging them.

[0003] Currently, the dustproof interfaces or dust covers used around the gate valve only have one opening on the top or side. Workers can only turn the gate valve through the narrow opening. This is limited by the location and space of the dustproof interface or dust cover, making it very inconvenient for workers to turn the gate valve. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dustproof interface device for hydraulic supports in coal mining faces. This device can effectively prevent dust in the air from falling onto the stop valve through a flip-type dustproof component. When the two sets of flip-type semi-dustproof covers are opened, the stop valve can be fully exposed. When the operator rotates the stop valve, he / she will not be restricted by the location of the dustproof device and will be able to rotate the stop valve more easily.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:

[0006] A dustproof interface device for a hydraulic support in a coal mining face includes a detachable positioning assembly installed on a hydraulic pipe. The detachable positioning assembly includes an upper positioning clamp and a lower positioning clamp, which are detachably installed above and below the hydraulic pipe, respectively.

[0007] A flip-type dustproof assembly capable of completely surrounding the shut-off valve is rotatably mounted on the detachable positioning assembly. The flip-type dustproof assembly includes two sets of flip-type semi-dustproof covers. The bottom of the flip-type semi-dustproof covers is rotatably mounted on the lower half positioning hoop, and a locking assembly is installed on the top of the flip-type semi-dustproof covers.

[0008] The two sets of flip-up semi-dust covers can fully expose the shut-off valve when flipped down from the top, and can completely surround the shut-off valve when flipped up from the bottom.

[0009] Using the above solution, the device can effectively prevent airborne dust from falling onto the shut-off valve through the flip-type dustproof component. When the two sets of flip-type semi-dustproof covers are opened, the shut-off valve can be fully exposed. When the operator rotates the shut-off valve, he / she will not be restricted by the location of the dustproof device and will be able to rotate the shut-off valve more easily.

[0010] As a preferred embodiment of the dustproof interface device for hydraulic supports in coal mining faces, the flip-type semi-dustproof cover is a transparent cover that allows for visualization.

[0011] The above solution uses a transparent cover for dust protection to facilitate observation of the internal shut-off valve status, making it more convenient to use.

[0012] As a preferred embodiment of a dustproof interface device for a hydraulic support in a coal mining face, the top of the flip-type semi-dustproof cover is an inclined arc surface, which gradually decreases from the inside to the outside.

[0013] In order to reduce the accumulation of dust on the top of the flip-type semi-dust cover, the top of the cover is designed as an inclined arc surface, which can effectively reduce the accumulation of dust on the top of the flip-type semi-dust cover.

[0014] As a preferred embodiment of the dustproof interface device for hydraulic support in a coal mining face, the locking assembly includes a lock plate fixed to the top of the flip-type semi-dustproof cover, and two lock cylinders extending from both sides are fixed on the lock plate; a lock buckle is rotatably installed at one end of the lock cylinder; a keyhole is fixed at the end of the lock buckle, and a lock groove that cooperates with the keyhole is also provided at the end of the lock cylinder away from the lock buckle.

[0015] The lock plate has a clearance groove; when the two sets of flip-type semi-dust covers flip up from the bottom and can completely surround the stop valve, the lock cylinder is located in the clearance groove of the other lock plate. At this time, flipping the latch can lock the keyhole into the lock groove.

[0016] A protruding throttle is fixed to the side of the latch.

[0017] Using the above scheme, in order to fix the two sets of flip-type semi-dust covers after closing, when the two sets of flip-type semi-dust covers flip up from the bottom and can completely surround the stop valve, the lock cylinder is just located in the clearance groove of another lock plate. At this time, the flip-type latch can lock the keyhole into the lock groove, and the two sets of flip-type semi-dust covers can be completely fixed. The operation is simple and flexible.

[0018] As a preferred embodiment of the dustproof interface device for hydraulic support in a coal mining face, the upper half positioning hoop and the lower half positioning hoop are fixedly installed by bolt and nut assembly. The bottom of the lower half positioning hoop is fixed with a side ear plate, and two rotating shafts are fixed on the side ear plate. Two sets of flip-type semi-dustproof covers are respectively rotatably installed on the rotating shafts. The assembly relationship between the flip-type semi-dustproof covers and the rotating shafts is clearance fit.

[0019] In order to achieve the flipping of the two sets of flip-type semi-dust covers, the two sets of flip-type semi-dust covers are rotatably mounted on a rotating shaft so that they can be flipped from the bottom.

[0020] After adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. This device can effectively prevent airborne dust from falling onto the shut-off valve through the flip-type dustproof components. When the two sets of flip-type semi-dustproof covers are opened, the shut-off valve can be fully exposed. When the operator rotates the shut-off valve, he / she will not be restricted by the location of the dustproof device and will be able to rotate the shut-off valve more easily.

[0022] 2. To facilitate observation of the status of its internal shut-off valve, a transparent cover is used for dust protection, making it more convenient to use;

[0023] 3. In order to reduce the accumulation of dust on the top of the flip-type semi-dust cover, its top is designed as an inclined arc surface, which can effectively reduce the accumulation of dust on the top of the flip-type semi-dust cover.

[0024] 4. In order to fix the two sets of flip-type semi-dust covers after closing, when the two sets of flip-type semi-dust covers flip up from the bottom and can completely surround the stop valve, the lock cylinder is just located in the clearance groove of the other lock plate. At this time, the flip-type lock can lock the keyhole into the lock groove, and the two sets of flip-type semi-dust covers can be completely fixed. Its operation is simple and flexible.

[0025] 5. In order to enable the two sets of flip-type semi-dust covers to flip, the two sets of flip-type semi-dust covers are rotatably mounted on the rotating shaft so that they can be flipped from the bottom. Attached Figure Description
