Abstract

The utility model discloses a prevention of out off top device for elevator comprising a breaker. The utility model is characterized in that the chassis of the breaker is fixed at the lower end of a mast, one end of a collision bar is connected with the switch rotation shaft of the breaker for controlling the switch of the breaker, the other end of the collision bar is provided with a rolling wheel, the rolling wheel extends into a guide sleeve, a steel wire rope passes though the guide sleeve from the center, and a movable clutch clamped by a bolt is installed on the steel wire rope above the guide sleeve. The movable clutch moves downward into the guide sleeve and collides the rolling wheel and the collision bar. The collision bar contacts the switch of the breaker and cuts the winding engine power to prevent the suspension cage top. The utility model has the advantages of high precision position, high reliability, convenient installation and fast adjustment.

Description

Elevator erosion control ejection device

The utility model relates to Architectural Equipment, especially relates to a kind of elevator erosion control ejection device.

Building hoist is widely used in occasions such as industrial building, civil construction, bridge construction, hoistway lifting at present, it is a kind of important vertical transport equipment, but this kind equipment in use device damage occurs and human casualty accident is of common occurrence, and its major cause is to lack a kind of safe and reliable erosion control ejection device.The Chinese patent of Granted publication CN2167079Y " height limiting device of arch type lifter " is though have the effect that prevents that effectively cage from rushing to summit, but it is loaded down with trivial details that it installs adjustment, the every rising of the height of elevator once, just needing the people to climb up adjusts once, and accuracy of positioning is low, fiduciary level is poor, uses maintenance complicated.

The purpose of this utility model be to provide a kind of accuracy of positioning height, fiduciary level height, simple in structure, easy for installation, adjust elevator erosion control ejection device efficiently.

The purpose of this utility model is achieved in that the utility model comprises cutout relay, feature is that the underframe of cutout relay is fixed on the guide rail bracket bottom, touching lever one end is connected with the switch turning cylinder of cutout relay, the switch of control cutout relay, the other end is equipped with roller, roller stretches in the orienting sleeve, and steel rope passes orienting sleeve from the centre, and movable collision block is clamped on the steel rope of orienting sleeve top with bolt.

Movable collision block is made up of two block-shaped size identity partss, and taper is processed at its two ends.

The utility model design has movable collision block and cutout relay, and when cage rose, movable collision block was to descending, when cage rises to the limes superiors position, be advanced in the orienting sleeve under the movable collision block, bump roller, touching lever is moved downward, touch the breaker switch handle, the switch of cutout relay is bumped to open position, cut off the winch main power source, winch stall and braking, cage stops to rise, thereby has prevented that cage from rushing to summit.Movable collision block can change its position on steel rope according to the needs of rising limiting altitude, therefore the utlity model has accuracy of positioning height, fiduciary level height, simple in structure, easy for installation, adjust advantage efficiently, be adapted at using on the elevator of all steel wire rope type transmissions.

Fig. 1 is installed in structural representation on the elevator for the utility model;

Fig. 2 is a structural representation of the present utility model.

Below in conjunction with embodiment and contrast accompanying drawing the disconnected type of this practicality is described in further detail.

Guide rail bracket 1 stands on the ground, and winch 8 drives cage 2 by steel rope 3 and moves up and down.The underframe 7 of cutout relay 6 is fixed on guide rail bracket 1 bottom, touching lever 11 1 ends are connected with the switch turning cylinder of cutout relay 6, the switch of control cutout relay 6, the other end is equipped with roller 10, roller 10 stretches in the orienting sleeve 5, and steel rope 3 passes orienting sleeve 5 from the centre, and movable collision block 4 is made up of two oad identity partss, movable collision block 4 links into an integrated entity by four bolts 9 and is clamped on the steel rope 3 of orienting sleeve 5 tops, and taper is processed at the two ends of movable collision block 4.
