Abstract
The utility model belongs to elevator overspeed governor field especially discloses a novel brake scotch and overspeed governor, the problem of the technique is solved provide a simple structure, can promote brake scotch and wire rope frictional force, make the overspeed governor carry the milder novel brake scotch and overspeed governor of pulling force, the technical scheme who adopts: including brake scotch seat and braking lining, brake scotch seat and braking lining fixed connection, the material of braking lining is friction material.
Description
Technical field:
The utility model belongs to elevator governor field, particularly relates 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.
Model utility content:
The utility model 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 adopted in the utility model 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 utility model 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 utility model compared with prior art has following beneficial effect: the utility model 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 utility model is described in more detail
Fig. 1 is the structural representation of brake shoe.
Fig. 2 is the lift force curve figure using the utility model brake shoe speed limiting device.
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.The utility model brake shoe is fixed by the box-like plate of locating stud 3 with speed limiting device.
The utility model 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 utility model 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 embodiment of the utility model.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 embodiment of the present utility model is explained in detail above, but the utility model 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 the utility model aim.
