Description

Technical Field

[0001] The present application belongs to the technical field of bucket elevators, and specifically relates to a skip elevator for underground coal mines. Background Art

[0002] Coal mine underground skip hoist is a vertical transportation equipment used in underground coal mines or other workplaces. It usually consists of a chain or belt conveyor mechanism equipped with a skip, which is used to lift ore, coal or other materials from underground to the ground or other required places. The main components of the underground skip hoist include the skip, transmission system, motor, support frame and fixed bracket, etc. The skip is usually made of strong steel plate and can withstand the load of heavy objects. The transmission system uses a chain or belt drive to transmit power and lift or lower the skip vertically. The motor provides driving force so that the skip can operate efficiently.

[0003] The safety of underground coal mine operations is extremely important because the coal mine operating environment is highly risky and complex. Bucket elevators for coal mines take up a large space, which can be reasonably utilized. On the premise of completing the basic functions of the elevator, it can be optimized to increase the possibility of escape for underground workers after an accident occurs.

[0004] For example, the application with publication number CN212387143U discloses a bucket elevator for coal mines, including an elevator body, a driving motor installed on one side of the elevator body, a connecting shaft symmetrically arranged inside the elevator body, a driving roller installed on the outer side wall of the connecting shaft, and a traction belt transmission-connected to the outside of the driving roller; the traction belt drives the bucket to perform a circulating operation by rotating, the moving bucket pushes one side of the movable plate, and flips one side of the movable plate upward along the groove until the bucket is separated from the movable plate, and the movable plate flips downward under the influence of gravity and connects to the next bucket, so that during the interval between buckets, the movable plate can block the material, making it difficult for the material to fall to the bottom of the elevator body, thereby ensuring the lifting efficiency, and the inner wall of the bucket can block the material entering the bucket because it is higher than the slot, making it difficult for the material to slip out, thereby reducing waste.

[0005] However, this application does not provide a response structure and method for safe escape when an accident occurs in a coal mine, and placing it in a limited space in a coal mine is a waste of resources. Utility Model Content

[0006] The purpose of the present application is to provide a skip hoist for an underground coal mine in order to solve the above-mentioned problem that there is no response structure and method for safe escape when an accident occurs in an underground coal mine.

[0007] The technical solution adopted in the present application is as follows: a skip hoist in a coal mine, comprising a main body shell, an outer surface of one side of the main body shell is fixedly connected to a motor body, an outer surface of the output end of the motor body is fixedly connected to a transmission tooth, an outer surface of the transmission tooth is movably connected to a chain, a positioning rod is provided on the outer surface of the chain, a positioning ring is movably connected to the outer surface of the positioning rod, a skip body is welded to the outer surface of the positioning ring, a movable shaft is provided on the outer surface of the upper end of the skip body, and the movable shaft is movably connected to a skip side plate corresponding to the outer surface of the skip body.

[0008] By adopting the above technical scheme, when the equipment is used, the main body shell is placed first, the inclination of the supporting shell is set by a hydraulic press at one end, and the friction is increased by a supporting gasket at the other end to ensure the stability of the equipment. The inclination angle of the supporting slide bar is fine-tuned by unscrewing the hexagonal screw to ensure the stable displacement of the bucket. The motor body provides mechanical power for the displacement of the bucket. The transmission teeth, chains, and positioning rods cooperate with the positioning rings to enable the bucket to be displaced periodically. The upper sides of the bucket body are provided with movable shafts so that the side plates of the bucket can rotate along the inner side of the bucket body at the center axis of the movable shaft. Coal mines are transported above the equipment, and the empty bucket is below. In case of danger, the upper supporting weight itself is high to provide buffering. When the whole is broken, the bucket is fixed in the hole between the supporting rod and the supporting beam to block most of the debris collapsed above. The trapped personnel below open the bucket by pushing the side plates of the bucket forward. When the inclination is large, they climb up the ladder formed by the supporting rod and the supporting beam to complete the escape. The overall equipment provides a possibility for safety when the underground space is limited, and ensures the reliability of coal mine production operations.

[0009] In a preferred embodiment, support rods are fixedly connected to the inner surface of the main body shell, and support beams are welded to the outer surface between the support rods.

[0014] By adopting the above technical solution, the supporting slide rod and the side support groove cooperate with each other, which increases the force effect of the equipment while ensuring the stability of the displacement of the bucket, thereby ensuring the mechanical efficiency of the bucket elevator.

[0015] In a preferred embodiment, a buffer support is provided on the middle outer surface of the support rod, and a buffer block is provided on the upper surface of the buffer support.

[0016] By adopting the above technical solution, the buffer block can be telescopically movable on the inner surface of the buffer support, and a spring is arranged inside to assist in supporting the side support groove to ensure the operating effect.

[0017] In a preferred embodiment, a transmission support body is fixedly connected to the inner surface of the main body shell corresponding to the transmission teeth, and the transmission support body is movably connected to the outer surface of the transmission teeth.

[0018] By adopting the above technical solution, the transmission support body is used to support the transmission teeth, thereby ensuring the stable operation of the entire transmission unit components.

[0019] In a preferred embodiment, a support shell is fixedly connected to the lower end of the inner surface of the main shell, a limit plate is welded to the outer surface of one end of the support shell, and an auxiliary support plate is welded to the outer surface of one end of the support shell away from the limit plate.

[0020] By adopting the above technical solution, the supporting shell provides a buffer space under the equipment bucket, while the empty bucket can be moved down to the maximum extent. The limit plate ensures that the bucket rotates when it goes down, ensuring that the bottom is downward and retaining the possibility of a safe passage. The auxiliary support plate assists in stabilizing the loading of the bucket.

[0021] In a preferred embodiment, a hydraulic press is provided below the limit plate on the inner surface of the main shell, and a support gasket is movably connected below the auxiliary support plate on the inner surface of the main shell.

[0022] By adopting the above technical solution, the hydraulic press provides a tilt angle setting for the equipment by lifting at one end, and the support gasket increases the friction at the other end to ensure the stability of the equipment.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
