Abstract
The invention pertains to the field of elevator speed limiters, in particular to a novel brake shoe and a speed limiter. In order to solve technical problems, the invention is aimed at providing the novel brake shoe and the speed limiter having a simple structure and capable of increasing friction force between the brake shoe and a steel wire rope such that lifting force of the speed limiter becomes smoother. The technical scheme adopted is characterized in that the novel brake shoe comprises a brake shoe seat and a brake lining; and the brake shoe seat is fixedly connected with the brake lining made by friction material.
Description
Technical field:
The invention belongs to elevator governor field, particularly relate to a kind of Novel brake watt and speed limiting device.
Background technique:
Elevator governor is one of safety con-trol part in elevator safety protection system.When elevator is in operation, no matter which kind of reason makes car exceed the speed limit, the danger of even falling, and in the inoperative situation of every other safety protection device, then speed limiting device and catch block generation linkage action, makes elevator cab stop.Lift power is one of speed limiting device main performance, namely for lifting catch block, the braking lining major part of existing speed limiting device brake shoe is all adopt sintered alloy material, but this alloy material in use lifts power change curve, and fluctuation ratio is larger, present change of rising, and friction factor is little, run not steady.
Summary of the invention:
The present invention overcomes the deficiency that prior art exists, and solves prior art Problems existing, aims to provide a kind of structure simple, can Hoist braking watt and friction force of steel rope, makes speed limiting device lift the milder Novel brake of power watt and speed limiting device.
For solving the problems of the technologies described above, the technical solution used in the present invention is: Novel brake watt, and comprise brake shoe seat and braking lining, brake shoe seat is fixedly connected with braking lining, and the material of braking lining is friction material.
Further, described brake shoe seat is metal material.
Further, described brake shoe seat is preset with dovetail groove, the side of braking lining is provided with the clamping joint with dovetail groove adaptability, and brake shoe seat to be coordinated with clamping joint by dovetail groove and the two junction plane adopts gluing to fix with braking to serve as a contrast.
Further, described brake shoe seat is preset with for fixing locating stud.
The present invention's another technological scheme claimed is: a kind of speed limiting device, comprises brake shoe, and described brake shoe is above-mentioned Novel brake watt.
The present invention compared with prior art has following beneficial effect: the present invention changes friction material into by the side (namely braking lining) contacted with wire rope by brake shoe, the friction factor of wire rope and brake shoe can be increased, promote frictional force, and after employing friction material, the change of speed limiting device lift force curve is mild.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention will be further described in detail
Fig. 1 is the structural representation of brake shoe.
Fig. 2 is the lift force curve figure using brake shoe speed limiting device of the present invention.
In figure: 1 is brake shoe seat, 2 is braking lining, and 3 is locating stud.
Embodiment:
As shown in Figure 1, Novel brake watt, comprise brake shoe seat 1 and braking lining 2, brake shoe seat 1 is fixedly connected with braking lining 2, and the material of braking lining 2 is friction material, and brake shoe seat 1 is metal material.The brake shoe seat 1 of metal material provides enough intensity, and braking lining 2 provides stable frictional force.
In order to the join strength between Hoist braking watt seat 1 and braking lining 2, described brake shoe seat 1 is preset with dovetail groove, the side of braking lining 2 is provided with the clamping joint with dovetail groove adaptability, brake shoe seat 1 with brake lining 2 and to be coordinated with clamping joint by dovetail groove and the two junction plane adopts gluing to fix.Be preset with on brake shoe seat 1 in addition for fixing locating stud 3.Brake shoe of the present invention is fixed by the box-like plate of locating stud 3 with speed limiting device.
The present invention's another technological scheme claimed is: a kind of speed limiting device, comprises brake shoe, and described brake shoe is above-mentioned Novel brake watt.
The present invention changes friction material into by the side (namely braking lining 2) contacted with wire rope by brake shoe, the friction factor of wire rope and brake shoe can be increased, promote frictional force, can find out as shown in Figure 2 after employing friction material, the change of speed limiting device lift force curve is mild.
Above content combines embodiment's accompanying drawing and has made detailed description to specific embodiments of the invention.In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
