Abstract

A slope-adaptive inclined special elevator includes a bumper, an elevator car system, a slope guide rail system, a counter-weight system, a traction machine, a governing rope governor, and a traction rope guiding wheel. The two ends of the traction rope are connected to the elevator car system and the counter-weight system respectively, and the traction rope is towed and lifted under the driving action of the traction machine and the guiding action of the traction rope guiding wheel; over-speed protection is realized by means of the governing rope governor and a safety gear linkage and the bumper; to adapt to slope variations, the car body is leveled automatically by an automatic leveling assembly, the traction rope is guided forcibly via traction rope lifting devices and traction rope pressing devices, and the governing rope is guided forcibly via governing rope lifting devices and governing rope pressing devices.

First claim

The invention claimed is:

1. A slope-adaptive inclined special elevator, comprising: a slope guide rail system arranged on a slope, an elevator car system, a counterweight system, traction rope lifting devices, traction rope pressing devices, a traction rope, traction rope guiding devices, a traction machine, a governing rope governor, governing rope pressing devices, a governing rope, governing rope lifting devices, and a governing rope tensioner; wherein
the slope guide rail system comprises a plurality of guide rail supports arranged at an interval on the slope, wherein each guide rail support comprises two vertical support plates arranged symmetrically and two cross plates, composed of an upper cross plate and a lower cross plate, connected between the two vertical support plates, elevator car guide rails are connected and fixed at two sides of the upper cross plates of the plurality of guide rail supports, and counterweight guide rails are connected and fixed at two sides of the lower cross plates;
the elevator car system is arranged on the elevator car guide rails and operates in a leveled attitude, the counterweight system connected to the elevator car system is arranged on a top of the counterweight guide rails, the traction rope lifting devices are arranged on the two cross plates of the guide rail supports respectively in a start section of the slope, the traction rope pressing devices are arranged on the two cross plates of the guide rail supports respectively in an upper section of the slope, and the traction rope guiding devices are arranged on the two cross plates of a last guide rail support respectively in the upper section of the slope; the elevator car system is driven via the traction rope lifting devices, the traction rope pressing devices, and the traction rope guiding devices;
the elevator car system comprises a car body and a pulley block arranged on a bottom of the car body, wherein front guide shoes and rear guide shoes are arranged below the pulley block, the front guide shoes and the rear guide shoes ride on the elevator car guide rails, one side of a front end between the car body and the pulley block is hinged to each other, a rear end of the car body is connected to an automatic leveling assembly, a bottom of the pulley block is connected to a first end of the traction rope, and a second end of the traction rope is connected to the counterweight system;
the traction machine is arranged at a top of the slope, and drives the traction rope to lead the elevator car system to move upwards or downwards, the governing rope governor and a traction rope guiding wheel are arranged at the traction machine, and the traction rope maintains a distance between the elevator car system and the counterweight system via the traction rope guiding wheel; a door at a bottom part of the slope corresponding to the elevator car system when the elevator car system lands at the bottom part of the slope and a door at the top part of the slope corresponding to the elevator car system when the elevator car system lands at the top part of the slope are arranged at a first side of the slope guide rail system, the governing rope lifting devices and the governing rope pressing devices are arranged at a second side of the slope guide rail system and are fixed to a ground, the governing rope is arranged above the governing rope lifting devices and below the governing rope pressing devices and forms a closed loop, an upper part of the governing rope is driven by the governing rope governor, and a lower part of the governing rope is tensioned via the governing rope tensioner.

2. The slope-adaptive inclined special elevator according to claim 1 , wherein a safety gear linkage is arranged on a bottom of the elevator car system.

3. The slope-adaptive inclined special elevator according to claim 1 , wherein a bumper is arranged at a lower end of the slope guide rail system.

4. The slope-adaptive inclined special elevator according to claim 1 , wherein the counterweight system comprises a rear counterweight, a front counter-weight hinged to the rear counterweight, and counterweight guide shoes arranged on a bottom of the rear counterweight and a bottom of the front counterweight respectively.
