Description

Technical Field

[0001] This patent relates to the field of aerial passenger transport devices in coal mines, specifically a full-line protection device for aerial passenger transport devices. Background Technology

[0002] Aerial passenger transport systems bear significant safety responsibilities as routine personnel transportation equipment in coal mines. In recent years, partial protection measures have been implemented, such as protection against overspeeding, slippage, emergency stop, rope derailment, tension reduction, and overrun. These protections are mostly concentrated at the head and tail sections of the system, and their principles are based on motor-driven brakes on the drive wheels and reducers. Under normal conditions, this provides adequate protection. However, reliable braking devices are lacking on transport lines long enough to be 300-800 meters. A suitable system is needed that not only provides full-line protection under extreme conditions but can also be tailored to the specific needs of each mine. Therefore, a comprehensive protection system for aerial passenger transport systems is required, which is compact, lightweight, and easy to install and maintain. Summary of the Invention

[0003] The purpose of this patent is to provide a full-line protection device for aerial passenger transport devices, in order to solve the problem of providing full-line protection for aerial passenger transport devices under extreme conditions in the aforementioned background technology.

[0004] To achieve the above objectives, this patent provides the following technical solution: a full-line protection device for an aerial passenger transport device, comprising a movable rope gripper, a cylinder and its accessories, an aerial passenger transport device crossbeam, U-bolts, a support base, a fixed rope gripper, a rope pulley, a steel wire rope, a pneumatic control cabinet, and a compressed air pipe, characterized in that: the upper end of the movable rope gripper is connected to the cylinder and its accessories, the cylinder and its accessories are fixed to the aerial passenger transport device crossbeam with bolts, the cylinder and its accessories are controlled by the pneumatic control cabinet to realize the linear movement of the cylinder to grip the steel wire rope; the middle part uses a round steel as a rotating shaft to realize torque transmission, the two sides of the round steel are sleeved on square steel with machined movable openings, one end of the square steel is welded to the aerial passenger transport device crossbeam; the lower end of the rope gripping surface is a knurled surface to increase friction.

[0005] The fixed rope gripper is a welded assembly, consisting of square steel and a rope gripping surface welded together. One end of the square steel is welded to the support base, and the support base is fixed to the crossbeam of the aerial passenger transport device with U-bolts. The rope gripping surface of the fixed rope gripper is knurled to increase friction.

[0006] Preferably, the movable rope gripper is a set of welded parts. The upper end pin mechanism is connected to the cylinder. The piston connection port of the cylinder has an elongated oval hole structure, which can realize the conversion of linear motion to circular motion. Utilizing the lever principle, the cylinder provides power to realize the action of gripping the wire rope. The lower end rope gripping surface is knurled with a roughness greater than 12.5.

[0007] Preferably, the fixed rope gripper is a set of welded parts, one end of which is welded to the support base and fixed in place. The movable rope gripper and the set together achieve the gripping of the wire rope. The surface of the rope gripper is knurled to a roughness greater than 12.5.

[0008] Preferably, the cylinder and its accessories are bolted to the support base and then fixed together on the crossbeam of the overhead passenger vehicle to provide power to the movable rope gripper. The power source is compressed air, and the action is controlled by a pneumatic control cabinet.

[0009] Compared with existing technologies, the beneficial effects of this patent are: the comprehensive protection system for the aerial passenger transport device.

[0010] This device utilizes simple mechanical principles to provide full protection along the 300-800 meter long transport line of the aerial personnel carrier. Even in extreme situations such as rope drop or breakage in the middle of the transport line, the aerial personnel carrier can achieve full-line braking, ensuring the safety of miners. Previous protection methods focused on the head and tail of the machine, and the braking principle was based on motor-driven wheels and reducers, failing to protect the middle section of the aerial personnel carrier and the entire steel cable line. This made it prone to loss of control after shaft or rope breakage. Attached Figure Description
