Abstract
The utility model discloses a safety brake which comprises a base, wherein a left brake arm and a right brake arm which correspond to each other are installed on the base in a rotary mode, both the left brake arm and the right brake arm are V-shaped, an arc-shaped brake shoe is installed in the middle of the left brake arm, an arc-shaped brake shoe is installed in the middle of the right brake arm, a connecting plate is installed at the upper end of the left brake arm, the outer side of the connecting plate is connected to a spring pull rod, a push rod is connected to the end of the outer side of the connecting plate, the bottom end of the push rod is installed on a pusher, and the inner end of the connecting plate is hinged to the upper end of the right brake arm through the pull rod. According to the safety brake, the structural design is reasonable; due to the arrangement of the arc-shaped brake shoes, friction generated during braking is reduced, and potential safety hazards caused by reduction of braking torque are reduced; the pusher drives the connecting plate to further drive the arc-shaped brake shoes on the left brake arm and the right brake arm to be combined, and in this way, braking efficiency is high; after braking is finished, the left brake arm and the right brake arm are driven to restore through the elastic force of the spring pull rod, then the arc-shaped brake shoes are made to restore to stop braking, the recovering performance is good, and using requirements are met.
Description
Technical field
The utility model relates to continuous rope continuous drafter field of components, relates in particular to a kind of sure brake.
Background technology
In the continuous traction winch of continuous rope, sure brake is that the torque of transmitting when movable parts (or movable machinery) or rotating speed are while exceeding certain limit value, movable parts (or movable machinery) is there is to the drg of braking function, existing sure brake is simple in structure, the friction force that in use arc brake scotch is subject to is large, after long-time use, easily there is the situation that lock torque declines, have potential safety hazard.
Utility model content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of sure brake is provided.
The utility model is achieved through the following technical solutions:
A kind of sure brake, include base, it is characterized in that: on described base, be rotatablely equipped with two mutual corresponding left and right brake control levers, the V-shaped structure of described left and right brake control lever, its middle part is provided with arc brake scotch, and the upper end of described left brake control lever is provided with connecting panel, the outside of described connecting panel is connected on spring pull bar, and the end in its outside is connected with push rod, and described push rod bottom is arranged on pusher, and the inner of described connecting panel is hinged by the upper end of pull bar and right brake control lever.
Between the bottom of described arc brake scotch and brake control lever, be provided with adjustment screw.
The utility model has the advantages that:
The utility model reasonable in design, the structure of arc brake scotch, has reduced the friction force producing in braking procedure, reduce lock torque decline and brought potential safety hazard, drive connecting panel by pusher, and then drive the involutory of arc brake scotch on left and right brake control lever, brake work efficiency high, after end of braking, drive left and right brake control lever to reset by the elastic force of spring pull bar, and then arc brake scotch is resetted, braking stops, restore funcitons is good, has met operating needs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, a kind of sure brake, include base 1, on base 1, be rotatablely equipped with two mutual corresponding left and right brake control levers 2,3, left and right brake control lever 2,3 V-shaped structures, its middle part is provided with arc brake scotch 4, the upper end of left brake control lever 2 is provided with connecting panel 5, and the outside of connecting panel 5 is connected on spring pull bar 6, and the end in its outside is connected with push rod 7, push rod 7 bottoms are arranged on pusher 8, and the inner of connecting panel 5 is hinged with the upper end of right brake control lever 3 by pull bar 9.Between the bottom of described arc brake scotch 4 and brake control lever, be provided with and adjust screw 10.
Claims (2)
1. a sure brake, include base, it is characterized in that: on described base, be rotatablely equipped with two mutual corresponding left and right brake control levers, the V-shaped structure of described left and right brake control lever, its middle part is provided with arc brake scotch, the upper end of described left brake control lever is provided with connecting panel, the outside of described connecting panel is connected on spring pull bar, and the end in its outside is connected with push rod, described push rod bottom is arranged on pusher, and the inner of described connecting panel is hinged by the upper end of pull bar and right brake control lever.
