Abstract

A mining elevator lapping platform suitable for a flexible guide rail and a mining elevator lapping method. The lapping platform mainly comprises a support claw package ( 1 ) and a power package ( 2 ), wherein the support claw package ( 1 ) comprises a mounting plate ( 1 - 14 ), a screw rod bearing base ( 1 - 15 ), a screw rod ( 1 - 4 ), a screw nut ( 1 - 2 ), a support rod ( 1 - 5 ), a pushing rod ( 1 - 3 ), a support claw ( 1 - 6 ). a footboard ( 1 - 7 ), a guide rail ( 1 - 9 ) and a guide rail frame ( 1 - 12 ); the power package ( 2 ) comprises an explosion-proof motor ( 2 - 1 ) and a bevel gear; and the support claw package ( 1 ) and the power package ( 2 ) are both installed on a cross beam ( 3 ) below an elevator car. The lapping method is as follows: the sharing between a lapping platform and a plurality of horizontal planes is realized, the self-locking function is achieved, the reliable connection of the lapping platform in the plurality of horizontal planes is met, the reliable lapping between the elevator car and a hoistway layer door is realized, and the mining elevator lapping platform plays a role in safety protection, and convenience of getting in and out of the elevator for cargos and people.

First claim

The invention claimed is:

1. A mining elevator lapping platform suitable for flexible guide rail, comprising:
a support claw package comprising:
two mounting plates arranged in symmetry on a bottom beam of the elevator car;
a support rod shaft arranged on the left between the two mounting plates and fixed via a mounting base;
a screw rod bearing housing arranged in the middle of the two mounting plates at certain spacing to the support rod shaft and perpendicular spatially to the support rod shaft;
a screw rod arranged in the screw rod bearing housing;
a driven bevel gear arranged on the right end of the screw rod;
a screw rod nut fitted over the screw rod;
a push rod hinged to the screw rod nut;
a support rod hinged to the middle part of the push rod and fixed to the support rod shaft; and
wherein together the screw rod nut, push rod, support rod, and screw rod constitute an in-line slider-crank mechanism;
a support claw hinged to the other end of the push rod;
a guide rail arranged on the upper part of the support claw and fixed in a guide rail bracket via a pin shaft; and
a foot board arranged on the outer side of the lower part of the support claw; and

a power package operably coupled to the support claw package comprising:
an explosion-proof motor fixed to the bottom beam of the elevator car; and
a driving bevel gear arranged on the output shaft of the explosion-proof motor and engaged with the driven bevel gear.

2. A lapping method for the mining elevator lapping platform suitable for flexible guide rail as set forth in claim 1 , comprising:
deploying the lapping platform, wherein the explosion-proof motor drives the driving bevel gear, the driving bevel gear drives the driven bevel gear, and the driven bevel gear drives the screw rod to rotate, so that the screw rod nut fitted over the screw rod moves horizontally, and thus drives the in-line slider-crank mechanism;
wherein the movement of the in-line slider-crank mechanism converts the movement of the push rod into upward vertical translation movement, the support rod rotates around the support rod shaft on the mounting base, and the pin shaft hinged to the support claw on the push rod moves along the trace, so that the foot board fixed to the support claw laps horizontally; and
retracting the lapping platform, wherein the explosion-proof motor rotates in a reverse direction, so that the screw rod rotates in a reverse direction and the screw rod nut is driven to move in a reverse direction, and the support claw is retracted along the trace and is then reset.
