Abstract

A mining elevator carrying platform and carrying method, the platform comprises a power system ( 1 ) and a four-rod carrying device ( 5 ), a rotating rod ( 3 ) connected with the power system ( 1 ) is set on the carrying device ( 5 ); the power system ( 1 ) comprises a flameproof motor ( 1 - 1 ), a upper-limited switch ( 1 - 2 ), a down-limited switch ( 1 - 5 ) and a main pulley ( 1 - 6 ), the flameproof motor ( 1 - 1 ) is connected with the main pulley ( 1 - 6 ) through a main steel cable ( 1 - 4 ), a baffle ( 1 - 3 ) is set on the main steel cable ( 1 - 4 ), a double cable channel is set on the main pulley ( 1 - 6 ), and the main pulley ( 1 - 6 ) is connected with a sub-pulley ( 1 - 8 ) by a sub-steel cable ( 1 - 7 ), a sliding plate ( 1 - 9 ) is set on the sub-steel cable ( 1 - 7 ), and a sliding rod ( 1 - 10 ) is set on the sliding plate ( 1 - 9 ). The main pulley ( 1 - 6 ) is driven to rotate by the flameproof motor ( 1 - 1 ) through the main steel cable ( 1 - 4 ), thus the sub-pulley ( 1 - 8 ) is driven to rotate. The sliding rod ( 1 - 10 ) moves in a strip-opening sliding slot in the rotating rod ( 3 ) by the sliding plate ( 1 - 9 ) moving up and down, then the rotating rod ( 3 ) and a carrying plate ( 5 - 1 ) are driven to move circumferentially. A rocker ( 5 - 3 ) is rotated around a supporting bracket ( 5 - 4 ) driven by a connecting rod ( 5 - 2 ), thus a credible carrying platform in multi-plane is realized. The platform is simple in structure, controlled accurately, convenient to be fixed and maintained, operated stably and reliably, and has the self-locking function.

First claim

The invention claimed is:

1. A mining elevator carrying platform, comprising:
a power system fixed to an elevator car and a four-rod carrying device, wherein, a rotating rod connected with the power system is arranged on the carrying device;
the power system comprises:
an explosion-proof motor, an upper limit switch, a lower limit switch, and a main pulley that are fixed to a bottom beam of the elevator car in sequence, the explosion-proof motor is connected with the main pulley via a main steel cable wound on the explosion-proof motor, a stop plate is arranged on the main steel cable, the main pulley has a double cable channel, and is connected with a sub-pulley fixed to a side beam of the elevator car via a sub-steel cable, a sliding plate is arranged on the sub-steel cable, and a sliding rod is arranged on the sliding plate, the rotating rod has a strip-opening sliding slot fitted over the sliding rod designed to fixedly rotate the rotating rod relative to the sliding rod; and

the carrying device comprises:
a supporting bracket fixed to a ground sill support of the elevator car and a carrying board that is fixedly connected to the rotating rod and can rotated around a rotating shaft of the ground sill support, a rocker connected with the supporting bracket is provided on a lower part of the carrying board, and a connecting rod connected with the carrying board is provided on the rocker.

2. The mining elevator carrying platform according to claim 1 , wherein, strengthening ribs are provided under the carrying board and a supporting plate rib supported on the rocker is provided on an outer end of the carrying board.

3. A carrying method for the mining elevator carrying platform of claim 1 , wherein:
when the elevator car lands, the explosion-proof motor drives the main steel cable, the main steel cable drives the main pulley to rotate, and the sub-steel cable wound on the main pulley drives the sub-pulley to rotate at the same time, the sliding plate moves up and down so that the sliding rod moves in the strip-opening sliding slot of the rotating rod, and thereby the rotating rod and the carrying board are driven to move circularly, and the connecting rod drives the rocker to rotate around the supporting bracket;
when the stop plate on the main steel cable hits the upper limit switch, the explosion-proof motor stops, the end face of the rocker abuts against the end face of a supporting plate rib on the carrying board, and the carrying board reaches a preset position and self-locks, so that the persons and goods can enter or exit the elevator car via the carrying board; and
when the landing door and elevator car door are closed, the explosion-proof motor drives the main steel cable and thereby drives the main pulley to rotate in reverse direction, and, when the stop plate hits the lower limit switch, the explosion-proof motor stops, and the carrying board is retracted and reset.
