Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor safety protection, and specifically relates to an emergency stop device for a belt conveyor. Background Art

[0002] The mine belt conveyor, also known as a conveyor, is an essential key device in coal mine and mining production. It is mainly used to continuously and efficiently transport materials such as coal and ore from the mining point or processing area to the designated location. The mine belt conveyor is usually composed of wear-resistant and high-strength belts, which, driven by driving rollers and tensioning rollers, achieve continuous material transportation. Its high efficiency, automation, and long-distance transportation ability greatly improve the efficiency and safety of mining production.

[0003] However, during the operation of the mine belt conveyor, various emergencies may occur, such as belt deviation, slipping, tearing, or material accumulation and blockage. These situations will not only affect the production progress but also pose a threat to the safety of equipment and personnel. Therefore, in order to promptly respond to these emergencies, emergency stop devices are usually equipped on the mine belt conveyor.

[0004] The emergency stop device is an emergency braking device that can quickly cut off the power supply or stop the belt movement when the belt conveyor malfunctions, thereby preventing the situation from deteriorating further. Among them, the pull-wire emergency stop switch is a relatively common emergency stop device. It arranges pull ropes along the belt conveyor. When an abnormal situation is detected, the staff can quickly pull the pull rope to immediately stop the belt conveyor from working.

[0005] However, if multiple emergency stop devices are connected by steel ropes and the steel ropes become loose or damaged, the emergency stop devices will not be able to function effectively. This will not only lead to the failure of emergency braking but also may exacerbate the severity of the accident. Therefore, during the daily maintenance and inspection of the mine belt conveyor, it is necessary to ensure the integrity of the emergency stop devices and their connecting components to cope with possible emergencies and ensure production safety. Content of the Utility Model

[0006] In view of this, the utility model provides an emergency stop device for a belt conveyor, which can make the connection between the emergency stop device and the steel rope more firm and avoid the emergency stop device from failing to function due to the loosening of the steel rope.

[0007] The utility model is implemented as follows:

[0008] The utility model provides an emergency stop device for a belt conveyor, which comprises a housing. A main component for controlling the start and stop of a motor is arranged inside the housing. Two swing arms are arranged at the front end outside the housing. The two swing arms are symmetrically distributed at the center and the included angle therebetween is 180°. A pull ring is arranged at the top of each swing arm. The pull ring is rotatably connected to the top end of the swing arm. Among them, a fixing component for fixing a steel wire rope is arranged on the pull ring.

[0009] On the basis of the above technical solution, the emergency stop device for a belt conveyor of the utility model can be further improved as follows:

[0010] Among them, the pull ring is rectangular, one end is rotatably connected to the swing arm through a rotating shaft, and the fixing component is detachably connected to the pull ring.

[0011] Furthermore, the fixing component comprises a fixing upper cover, a fixing groove and a fixing pin. The fixing upper cover is detachably connected to the front end face shell of the pull ring. Linear fixing grooves are arranged on one side of the fixing upper cover close to the pull ring and the front end face of the pull ring. The fixing grooves on the fixing upper cover and the pull ring are symmetrically arranged face to face. Fixing pins are arranged on the surface of the fixing groove. The fixing pins are integrally formed with the fixing upper cover and the pull ring.

[0012] The beneficial effect of adopting the above improvement scheme is that by arranging the fixing groove, it is convenient to place the steel wire rope, and by arranging the fixing pin, the steel wire rope is tightly fixed in the fixing groove and cannot move.

[0013] Furthermore, the groove formed by the fixing grooves on the pull ring and the fixing upper cover is cylindrical, one end penetrates through the side wall of the fixing upper cover, and the other end is located inside the fixing upper cover.

[0014] Furthermore, the length of the fixing pin is equal to 4 / 5 of the radius of the cylinder formed by the fixing grooves.

[0015] Furthermore, the shape of the fixing groove is U-shaped.

[0016] The beneficial effect of adopting the above improvement scheme is that by arranging the shape of the fixing groove to be U-shaped, it is convenient for the installation of the steel wire rope and improves the construction efficiency of workers.

[0017] Furthermore, the shape of the fixing groove is S-shaped.

[0018] The beneficial effect of adopting the above improvement scheme is that by arranging the shape of the fixing groove to be S-shaped, the fixing of the steel wire rope is more firm.

[0019] Furthermore, the shape of the fixing groove is spiral.

[0020] The beneficial effects of adopting the above improvement scheme are as follows: By setting the shape of the fixed groove as spiral, while the steel wire rope is firmly fixed, the bending radian of the steel wire rope is small, which is convenient for installation.

[0021] Furthermore, the pull ring and the fixed upper cover are detachably connected by bolts.

[0022] Furthermore, the pull ring and the fixing component are made of cast aluminum or stainless steel.

[0023] Compared with the prior art, the beneficial effects of a belt conveyor emergency stop device provided by the present utility model are as follows:

[0024] Convenient and safe operation: There are two swing arms symmetrically distributed at the center outside the device, and a rotatable pull ring is provided at the top of each swing arm, enabling the operator to quickly pull the pull ring to trigger the emergency stop mechanism in an emergency, thereby quickly stopping the operation of the belt conveyor and ensuring operation safety.

[0025] Efficiently fix the steel wire rope: The pull ring is designed with a fixing component for fixing the steel wire rope, including a fixed upper cover, a fixed groove and a fixed pin. This design not only facilitates the installation and disassembly of the steel wire rope, but also ensures the stable fixing of the steel wire rope, improving the reliability and stability of the overall device.

[0026] Diversified fixed groove design: The shape of the fixed groove can be designed as U-shaped, S-shaped or spiral according to requirements, and these designs have their own advantages. The U-shaped groove is convenient for installation, the S-shaped groove increases the fixing strength, while the spiral groove reduces the bending radian of the steel wire rope while ensuring firmness, which is convenient for installation. This flexibility enables the device to adapt to different working environments and requirements.

[0027] Excellent material: The pull ring and the fixing component are made of high-quality materials such as cast aluminum or stainless steel, having good corrosion resistance and wear resistance, which can extend the service life of the device and reduce the maintenance cost.

[0028] Compact structure and easy to maintain: The overall structure of the device is reasonably designed, compact and easy to maintain. When components need to be replaced or repaired, the relevant components can be conveniently disassembled and installed.

[0029] Improve production safety: In industrial production, the emergency stop function of the belt conveyor is crucial. The emergency stop device of the present utility model can quickly respond and stop the operation of the belt conveyor, effectively preventing safety accidents caused by equipment failures or operation mistakes, and improving the production safety level.

[0030] In summary, the belt conveyor emergency stop device of this utility model has significant advantages such as convenient operation, safety and efficiency, and easy maintenance, which is of great significance for improving the safety and efficiency of industrial production.
