Abstract

The utility model relates to a new roller guide shoe of hoist, comprising a roller seat 3, a lateral guide wheel connected with a crank and a pair of alignment guide wheels 61a and 61b connected with a torsion spring. The pressure of a spring 22 is acted on a crank 21 to drive the lateral guide wheel 5 to press tightly on bottom side face of guide rail of a channel steel 8. The pressure of a spring 62 is acted on a torsion spring 6 to make the torsion spring generate torsion force and the torsion spring 6 drives the alignment guide wheels 61a and 61b to automatically press against bother inner side faces 81 and 82 of guide rail of the channel steel 8. Each guide wheel automatically aligns, meshes with and combines with guide rails of the channel steel, so that the lifting or elevator cabin can automatically locate weights of both the front and rear directions and move upward and downwards without deviation and wobbling which can also provide efficient guarantee in performing flat-layer location and limit stop control for the elevating gear at the same time.

Description

The elevator roller guide shoe

Technical field

The utility model relates to the roller guide shoe device that cooperates with guide rail of elevator or elevator.

Background technology

Roller guide shoe is the bridge case that is installed in elevator, elevator, four jiaos of slider roller devices that cooperate with guide rail of locating of left and right sides upper and lower side of counterweight body.

The slide rail of present high-grade elevator mainly is a T type guide rail of adopting special manufacturing, and roller guide shoe also is to be fit to T type Guide Rail Design specially.And most elevator gears is to adopt channel-section steel as guide rail; the bridge case of the elevator of existing mating groove steel guide rail and elevator and the roller guide shoe on the counterweight body all are to be made of the better simply fixed idler whell of structure; the bridge case; when each guide wheel at four jiaos of places cooperates with the channel-section steel guide rail on the counterweight body; can not all be pressed on the inner groove surface of guide rail channel-section steel fully in the automatic compensation location; tolerance clearance is big between guide wheel and channel-section steel inner groove surface; make elevator; the bridge case of elevator and counterweight body produce skew and swing in operational process; move not steady; produce bigger vibration and dry sound; because operation is not steady; also be unfavorable for jacking system is carried out flat bed location and position limitation protection control

Summary of the invention

But the purpose of this utility model provides a kind of self-orientation that uses at the channel-section steel guide rail, the elevator that operates steadily, elevator roller guide shoe.

The technical solution of the utility model is by roller mount 3; by load be connected on the roller mount 3 cooperate with guide rail channel-section steel bottom surface by the elasticity bonded assembly side guide wheel 5 of cranking arm; by load be connected on the roller mount 3 cooperate with guide rail channel-section steel two sides by a pair of centering guide wheel of elasticity pivoted arm bonded assembly 61a; 61b constitutes; side guide wheel 5 tightly is pressed against on the channel-section steel bottom surface automatically under the supporting of cranking arm by action of the spring and rolls; make lifting; the bridge case of elevator; the left and right directions self-orientation of counterweight body; centering guide wheel 61a; 61b tightly is pressed against on the channel-section steel two sides automatically respectively under the centering pivoted arm by action of the spring drives and rolls; make lifting; the bridge case of elevator; the fore-and-aft direction self-orientation of counterweight body; be no gap self-orientation near cooperating between three rollers of roller guide shoe and channel-section steel guide rail; make the bridge case of jacking system or elevator; the counterweight running body is steady; do not produce skew and swing, this also jacking system is carried out the flat bed location and position limitation protection control gives effective assurance
