Description

Vertical shock absorption buffer seat for passenger elevator counterweight device

Technical Field

The utility model relates to a passenger elevator technical field specifically is a vertical shock attenuation buffer seat for passenger elevator counterweight.

Background

The counterweight device is a structural functional component which must be configured for a passenger elevator, mainly comprises a counterweight and a weight compensation device, is used for relatively balancing the weight of the elevator car, can keep the weight difference between the elevator car and the counterweight within a limit during the operation of the elevator, and ensures the normal traction and transmission of the elevator. The counterweight is essentially a counterweight and functions as dynamic balance, and in terms of function, the counterweight is a component of an elevator traction system and functions to reduce the power of a traction motor and the torque on a traction sheave and a worm wheel. The counterweight device is installed in a hoistway of an elevator, and is connected with a car through a traction sheave by a traction rope, so that the weight of the car and a payload part are balanced, and the energy consumption and the loss of the motor power are reduced. In the running process of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoe to play a role in balancing in running.

At present passenger elevator is with counterweight structure has the multiple, but no matter what kind of to heavy form, all adopts to correspond on four angles of counterweight to set up four and lead boots in order to guarantee to move along counterweight guide rail vertical operation when the elevator moves, must install the buffer in counterweight bottom moreover, and should adopt removable buffer, and the purpose is exactly the shock attenuation that reduces in going down the motion to counterweight, reduces the vibrations influence to the car to guarantee passenger elevator's operating stability and comfort level.

The buffer of the existing counterweight device is arranged at a station in the middle of a beam at the bottom of the counterweight device, an upper-lower double-layer structure is adopted, namely the buffer is composed of a positioning seat and a supporting seat, and the positioning seat fixes the whole set of buffer on the bottom surface of the beam of the counterweight device through a bolt to form a convex rectangular frame structure assembly; the supporting seat is the striking block, the top of the supporting seat is fixedly connected with the positioning seat through a bolt, and the bottom plane of the supporting seat strikes against the vertically raised buffer seat in the elevator shaft, so that the bottom building stopping motion effect is realized. As for the existing buffer at the bottom of the counterweight device, the structure is simple, the buffer is fixedly connected through bolts, and the buffer is convenient and fast to disassemble and assemble in daily use; because car and counterweight quality are great, and the intensity requirement of perpendicular descending acceleration of gravity to building end structure spare is higher, so adopt all metal material (Q-235A hot rolled steel plate) welded forming, can satisfy the end of building in passenger elevator car and the counterweight reciprocating motion and stop the needs, still have certain not enough, promptly:

(1) The bottom building stability is poor and the vibration is easy: the counterweight buffer and the well buffer seat are both metal structural parts, so that the strength is high, the rigidity is good, the yield and bending resistance is strong, the rigidity is deficient, the flexibility is poor, the car and the counterweight are stopped by building a bottom stop (stopping) by the buffer structure under the action of the gravity acceleration, the surface contact of the buffer structure is completely relied on, and the plane of the metal structure belongs to hard landing, so that the running stability and the comfort degree of the passenger elevator are influenced to a certain extent.

(2) The buffer contact surface has deformation phenomenon: the buffer structure member adopts a rectangular frame structure, the upper plane and the lower plane are rectangular steel plates, the middle part is a hollow upright post made of square steel, the impact load resistance of the inner side of the square upright post is superior to that of the outer side, particularly four corner areas, the local collapse and deformation of corners are easy to occur, the stability of the buffer structure member during bottom building can be influenced, and the service life of the buffer structure member can be reduced.

(3) The double-layer structure connecting bolt is easy to loosen: buffer structure adopts double-deck perpendicular stack shape system from top to bottom, connects fixedly by 4 pieces of M106 hex bolts and nuts, because of receiving long-time striking influence, connects the bolt of usefulness and easily appears the not hard up phenomenon of nut, though set up lock washer still can not fundamentally eliminate the not hard up phenomenon of nut, especially the well is in long-term unmanned on duty state, in case the nut is not hard up the back and in time discover to deal with, not only can cause the elevator trouble, causes the potential safety hazard to a certain extent. At present, the problem is not solved fundamentally because the maintenance expense is increased to a certain extent by adopting a regular inspection and maintenance mode for disposal.
