Mining elevator

A mining elevator operable between an upper platform and a lower platform, the mining elevator comprising:

• an explosion-proof traction system;
• an explosion-proof elevator car protection system;
• a flexible guide rail guiding system arranged between the upper platform and the lower platform;
• and
• a composite elevator car and a counterweight system that run up and down along a guide rail of the flexible guide rail guiding system;
• wherein the explosion-proof traction system comprises an explosion-proof traction machine connected to an explosion-proof control cabinet and a traction rope wound on the explosion-proof traction machine, wherein, one end of the traction rope is connected to a traction rope terminating device fixed to the upper platform, and the other end of the traction rope is provided with a traction rope tension regulator fixed to the upper platform;
• wherein the explosion-proof elevator car protection system comprises a rope gripper, a speed limiter, a speed limiter rope, first and second hydraulic dampers, a braking rope connector, a speed limiter rope tensioner, a safety clamp, a safety clamp link mechanism, a braking rope, and a braking rope damping tensioner, wherein, the rope gripper is arranged on the traction rope between the traction machine and at least one guide pulley, the speed limiter is fixed to the upper platform, the first and second hydraulic dampers and the speed limiter rope tensioner are fixed to the lower platform, the speed limiter rope is connected between the speed limiter and the speed limiter rope tensioner, an upper end of the braking rope is connected to the braking rope damping tensioner and a lower end is connected to the braking rope connector, and a plurality of braking rope guiding sleeves and the safety clamp fixed to the composite elevator car are arranged on the braking rope;
• wherein the flexible guide rail guiding system comprises steel rope guide rails, guide rail tensioners fixed to the upper platform and connected to an upper end of the steel rope guide rails, and guide rail connectors fixed to the lower platform and connected to a lower end of the steel rope guide rails, wherein, a plurality of flexible guide rail guiding sleeves fixed to the composite elevator car are arranged on the steel rope guide rails;
• wherein the composite elevator car comprises a car body with a rail provided in the car body, and a trailing cable suspended to a bottom of the car body, wherein, an explosion-proof control box for controlling is arranged in the car body, car arresters are arranged on the rail, and a supporting platform for access of a mine car is arranged atan entry of the composite elevator car;
• wherein the counterweight system comprises a counterweight for balancing with the composite elevator car, a compensating rope suspender arranged on a lower part of the counterweight, and a compensating rope connected to the compensating rope suspender;
• and
• wherein a plurality of braking rope guide sleeves are fixed to two sides of the car body respectively, with three guide sleeves on each side, wherein two guide sleeves are fixed to an upper side and a lower side of the safety clamp, and the other guide sleeve is fixed to an upper side of the car body.
