Abstract

The utility model relates to an elevator accident prevention, concretely relates to anti -falling protection device of elevator, including setting up the buffer gear in the elevartor shaft bottom, buffer gear includes shock pad, damping spring and fixed plate, the shock pad distributes from top to bottom, and installs damping spring between two shock pads, installs the fixed plate that is used for fixed damping spring between shock pad and the damping spring, still including setting up the reduction gear at the elevator bottom half. The utility model discloses make the elevator in the buffering of in -process through 2 shock pads and a set of a plurality of damping spring of falling, impact force in the time of can reducing to fall greatly to the guarantee personal safety, the setting is at the reduction gear of elevator bottom half, and the circumstances and signals that measuring elevator that can be accurate falls control reverse fan work, let elevator bottom when falling produce the back draught for the elevator slows down, reduces the momentum of elevator when falling to the buffer gear in shaft bottom, protection passenger safety.

Description

A kind of elevator fall protection equipment

Technical field

The utility model relates to elevator safety technology, is specifically related to a kind of elevator fall protection equipment.

Background technology

Along with day by day frequently occurring of used during elevator falling accident, a kind of invention of used during elevator falling safety guard is extremely urgent, and used during elevator falling is very large to the impulsive force of bottom, often jeopardizes personal safety.

The lifter apparatus such as elevator relate to human safety issues, when control system is out of control fall time, requiring a set of independently detector can detect in time and brake immediately.In prior art, common solution adopts mechanical velocity limiter, and the steel wire namely when car is walked by being attached thereto drives governor sheave to rotate, and when speed is higher than threshold values, the centrifuge arm touching safety switch on pulley, provides the signal that falls.The method of the mechanical velocity limiter of this employing needs the mechanical mechanisms such as steel wire, pulley, centrifuge arm, spring, steel wire length is proportional to story height, need consumable material more, also exist simultaneously and numerous and diverse problem is installed, cause the problems such as cost is high, construction is difficult, and in current elevator device, elevator keeps the state stopping at certain position, the band-type brake friction force of towing machine is relied on to stop the rotation of motor to realize.Once band-type brake lost efficacy, car or counterweight will fall along hoistway under gravity.This situation is once occur in level position of elevator enabling turnover passenger, and the personal injury accident of generation is very serious.Also do not have a kind of device initiatively can prevent the generation of this accident at present.Current embraces the device that the products such as rail device, wire holder are also the passive prevention car movements when producing fault, and can produce harmful effect to the life-span of elevator components.

Utility model content

For prior art Problems existing; the utility model provides a kind of elevator fall protection equipment; solving traditional elevator detects main comprehensive not by physical construction, and in drop event, safety guard is mainly through the problem easily causing passenger injured that contacts with each other.

For solving above technical matters, the utility model is achieved by the following technical programs:

A kind of elevator fall protection equipment, comprise the buffer gear be arranged on bottom elevator, described buffer gear comprises cushion blocking, damping spring and adapter plate, described cushion blocking distributes up and down, and between two pieces of cushion blockings, damping spring is installed, the adapter plate for fixing damping spring is installed between cushion blocking and damping spring; Also comprise the retarder be arranged on bottom elevator box, described retarder comprises acceleration pick-up, controller and reverse blower fan, and described acceleration pick-up connection control device, described controller controls reverse blower fan work.

Preferably, described cushion blocking is polyurethane foam material.

Preferably, described reverse blower fan quantity is at least 1.

Preferably, described elevator fall protection equipment also comprises urgent air bag, and described urgent air bag to be arranged on bottom elevator box and to be controlled by described controller.

Beneficial effect:

The utility model provides a kind of elevator fall protection equipment, by being arranged on the buffer gear bottom elevator, make elevator buffering through 2 pieces of cushion blockings and one group of multiple damping spring in drop event, greatly can reduce impulsive force when falling, to guarantee personal safety; Be arranged on the retarder bottom elevator box; can the situation of used during elevator falling be detected accurately and send signal; control reverse blower fan work; allow elevator when falling bottom produce back draught; make deceleration of elevator; reduce the momentum of elevator when falling the buffer gear to shaft bottom, protection passenger safety.
