Abstract

The utility model relates to guide rail calipers. The calipers comprise a calipers engine base (1), wherein the calipers engine base (1) is vertically provided with a dovetail groove; the dovetail groove is internally provided with a slide block (2) and the slide block (2) is symmetrically provided with wedged blocks (3) left to right; a wedged surface of each wedged block (3) is correspondingly matched with a groove wall of the dovetail groove; guide wheels (4) are symmetrically arranged at the upper part of the slide block (2) from left to right; a spring positioning block (2.1) is arranged on the back surface of the top of the slide block (2) and the spring positioning block (2.1) is located above the calipers engine base (1); one end of a spring (7) is connected with the bottom of the spring positioning block (2.1) and the other end of the spring is connected with the top of the calipers engine base (1); and the top of the spring positioning block (2.1) is connected with a rope leaning idler wheel (6) through a rope leaning connecting rod (5). The guide rail calipers disclosed by the utility model can improve the safety performance of aloft construction equipment including a hanging basket and the like.

Description

The guide rail clamp

Technical field

The utility model relates to a kind of guide rail clamp, especially relates to a kind of guide rail clamp that are used for plaing on the building hanging basket safety precaution effect.

Background technology

At present, the hanging basket that uses on the construction trade does not all have safety prevention measure, and easily because of the hawser fracture has an accident, serious also causes casualties easily, leads to the loss that can't retrieve in the work progress of high-altitude building.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of guide rail clamp that improve high-altitude preparation of construction safety performances such as hanging basket are provided.

The purpose of the utility model is achieved in that a kind of guide rail clamp; Said clamp include the clamp support, and said clamp support is vertically arranged with dovetail furrow, are plugged with a slide block in this dovetail furrow; Left-right symmetric is equipped with wedge on the said slide block; The lozenges of said wedge is symmetrically set with leading sheave with the corresponding coupling of the cell wall of dovetail furrow, said slide block top, and the said slider top back side is provided with a spring locating piece; And this spring locating piece is positioned at clamp support top; Have a spring one end to link to each other with the bottom of spring locating piece, the other end links to each other with the top of clamp support, and the top of said spring locating piece is through linking to each other by the rope roller with one by the rope connecting rod.

The utility model guide rail clamp, the dovetail furrow on the said clamp support is the trapezium structure of open upper end less than lower ending opening.

Compared with prior art, the beneficial effect of the utility model is:

After adopting the utility model guide rail clamp, when the situation of hawser fracture suddenly took place, wedge can clamp guide rail by fast speed, thereby plays necessary anti-fall safeguard procedures, helps to improve the safety performance of high-altitude preparation of construction.

Fig. 2 is the front elevation of the utility model guide rail clamp.

Wherein:

Clamp support 1, slide block 2, spring locating piece 2.1, wedge 3, leading sheave 4, by rope connecting rod 5, lean on restrict roller 6, spring 7.

The specific embodiment

Referring to Fig. 1 and Fig. 2, a kind of guide rail clamp that the utility model relates to, said clamp include clamp support 1; Said clamp support 1 is vertically arranged with dovetail furrow, and this dovetail furrow is the trapezium structure of open upper end less than lower ending opening, is plugged with a slide block 2 in this dovetail furrow; Left-right symmetric is equipped with wedge 3 on the said slide block 2; The lozenges of said wedge 3 and the corresponding coupling of the cell wall of dovetail furrow, said slide block 2 tops are symmetrically set with leading sheave 4, and the back side, said slide block 2 top is provided with a spring locating piece 2.1; And this spring locating piece 2.1 is positioned at clamp support 1 top; Have a spring 7 one ends to link to each other with the bottom of spring locating piece 2.1, the other end links to each other with the top of clamp support 1, and the top of said spring locating piece 2.1 is through linking to each other by rope roller 6 with one by rope connecting rod 5.

During use, the utility model guide rail clamp are installed in the right ends of high-altitude preparation of construction such as hanging basket, the lifting hawser of high-altitude preparation of construction such as hanging basket is affiliated to by rope roller 6, and the guide rail clamp are arranged on the guide rail, and guide rail is between two leading sheaves 4; This moment, wedge 3 did not contact with guide rail compression spring 7, thereby this moment simultaneously because the lifting hawser, makes that driving slide plate 2 by rope lever 5 moves down with wedge 3 to the compressing by rope roller 6; When fracture takes place in the lifting hawser; Forces by on the rope roller 6 disappears immediately; Thereby make slide block 2 on rapid under the promotion of spring 7, move; Because wedge 2 cooperates with dovetail furrow, make wedge 2 clamp guide rail fast brake action is timely played in downslide, guaranteed workmen's life security.

And in manufacturing and using, the guide rail clamp must satisfy following properties:

1) the suspension platform degree of tilt that vertically inclines in service is not more than 6 °, can pin also out of service automatically;

2) under the locking state, can not automatically reset;

When 3) bearing plate loading test, static 10min must not have any sliding phenomenon;

4) card rail pincers should be connected reliably with suspension platform, and its Joint strenght should be less than 1.5 times permission impulsive force;

5) guide rail clamp impulsive force computing formula is: F=fk

In the formula: F------allows impulsive force;

The f------coefficient of impact, value 2.5;

The gravity that half produced of deadweight of k------suspension platform and nominal payload sum;

6) card rail pincers must effectively use in the demarcation phase, and effectively the demarcation phase is not more than 1 year.

Claims
