Description

Explosion-proof elevator

Technical Field

The utility model relates to an explosion-proof safety equipment technical field, concretely relates to explosion-proof elevator.

Background

The industrial elevator is an electric dragging vertical transportation device which generally uses a plurality of independent steel wire ropes to drag a car to ascend and descend. When the elevator runs, the motor drives the traction sheave to run, and the extrusion force of the steel wire rope crossing the traction sheave to the traction sheave is utilized to generate the static friction force between the traction sheave and the traction steel wire rope to drive the traction steel wire rope to lift the lift car and the load. The principle of an explosion-proof elevator is the same as that of a common elevator, but the explosion-proof elevator has the performance required by the common elevator and also has the explosion-proof performance. Explosion-proof elevators must be designed to reliably prevent dangerous spark ignition and dangerous high temperature ignition.

A explosion-proof elevator for industrial purpose, often influence electric component normal work because of the dust gets into the switch board, can produce electrostatic interference between the dust, in case contact with electric component, just very easily cause the dust to adsorb, it is not good to lead to the interior radiating effect of switch board, can be because of high temperature in the switch board even, it explodes to lead to the dust of low ignition point, thereby and thereby the dust discharges elevator outside and guide rail friction production spark among the prior art, with the interior combustible gas emergence reaction of well, lead to gas explosion, influence the normal operating of elevator, do not guarantee to take personnel's life safety.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem that proposes in the above-mentioned technical background, provide an explosion-proof elevator, can realize collecting the dust and reduce the function of dust potential safety hazard to possess explosion-proof advantage, solved dust explosion, electrostatic interference, gas explosion scheduling problem.

The utility model adopts the following technical scheme:

the utility model provides an explosion-proof elevator, includes car and install bin, be provided with a pair of deciliter lift-cabin door in the car, deciliter lift-cabin door inboard symmetry is provided with infrared receiving and dispatching photoelectricity board, the install bin sets up car bottom, install bin inner wall top is equipped with a dust absorption section of thick bamboo, dust absorption bottom of thick bamboo left side is equipped with connection director's dust concentration sensor and temperature sensor, and the right side is equipped with the case of keeping in temporary, a dust absorption section of thick bamboo still connects the dust extraction fan through the dust extraction union coupling, the dust extraction fan passes through the dust exhaust union coupling and keeps in the case temporarily, the equal fixed mounting of dust extraction fan and case of keeping in the install bin bottom.

As the utility model relates to an explosion-proof elevator's preferred technical scheme, car and install bin all adopt the aluminum alloy preparation, a plurality of arranges orderly dust inlet hole has been seted up to the car bottom, dust inlet hole intercommunication car and suction tube.

As a preferred technical scheme of explosion-proof elevator, infrared receiving and dispatching photoelectric board detected signal output links to each other with elevator control system input port.

As the utility model relates to an explosion-proof elevator's preferred technical scheme, the install bin right side is equipped with the open-close plate, the case of keeping in can follow the open-close plate and take out.

The beneficial effects of the utility model are that:

the utility model discloses be provided with dust concentration sensor and temperature sensor, when dust concentration or temperature to the critical value in the suction drum, the controller just can start the dust extraction fan and carry out the dust exhaust to the dust in the suction drum to reach safe explosion-proof function.
