Abstract
The utility model discloses a kind of brake pad mounting structure, in the friction mechanism of ramp-down device, the friction mechanism includes swinging mounting and brake pad, the swinging mounting includes the support arm that cross section is polygon, the brake pad opens up shape mounting hole corresponding with the support arm and is slidably socketed on the support arm, and the vertex of the mounting hole sets the groove of invagination.Compared with prior art, since vertex of the utility model in brake pad upper installing hole is provided with groove, therefore the groove can be relied on to increase the width of vertex, it allows the apex angle of support arm that brake pad can be installed on support arm in the range of being located at groove in assembling, the assembly difficulty between support arm and brake pad can be reduced.
Description
Technical field
The utility model is related to escape device for high-rise buildings technical field more particularly to a kind of brake pad mounting structures.
Background technology
When earthquake, fire occurs when disasters, the personnel in high-storey building quickly can not reach in ground using elevator
Face, can only be by stair downlink, but the speed that stair is utilized to escape is too slow, and the personnel of often leading to can not escape from time.Although
Under the assistance of fire-fighting and rescue strength, the personnel in high building can also be escaped by aerial ladder or life saving gas cushion, but deteriorated in disaster and endangered
Fire-fighting and rescue strength can not necessarily be on the scene before machine personal safety, if escape gold will be affected adversely by blindly waiting for rescue
Time.
To enable the personnel in high building, when disaster occurs, timely voluntarily escape to ground, has developed at present
Relevant escape device, wherein most strong with the practicability of ramp-down device.Ramp-down device include coiling have the rotating member of steel wire rope with
And the friction mechanism in rotating member is arranged at, using frictional force rotating member is driven to rotate when steel wire rope is extracted out from rotating member.It rubs
Wiping mechanism includes swinging mounting and the slidably brake pad on the support arm of swinging mounting, rubs when swinging mounting rotates
Block is outwards thrown away by centrifugal forces affect and is contacted with rotating member inner wall, so as to generate frictional resistance to rotating member inner wall, with limitation
The rotating speed of rotating member.
The cross section of swinging mounting support arm is rectangular, and the mounting hole of a rectangle is opened up on brake pad and is installed to support arm
On.To prevent brake pad from occurring rocking during sliding on support arm, beat, the size of mounting hole, which is only slightly larger than, to be supported
Arm, four apex angles which results in the support arm in assembling are needed completely with four apex angles of mounting hole to that could will rub after just
Block is set on support arm, and assembly manipulation is more difficult.
It is necessary to provide a kind of mounting structures for reducing assembly difficulty between support arm and brake pad.
Utility model content
The purpose of this utility model is to provide a kind of mounting structures for reducing assembly difficulty between support arm and brake pad.
To achieve these goals, the utility model provides a kind of brake pad mounting structure, arranged on rubbing for ramp-down device
It wipes in mechanism, the friction mechanism includes swinging mounting and brake pad, and the swinging mounting includes the branch that cross section is polygon
Brace, the brake pad opens up shape mounting hole corresponding with the support arm and is slidably socketed on the support arm, described
The vertex of mounting hole sets the groove of invagination.
Compared with prior art, since vertex of the utility model in brake pad upper installing hole is provided with groove,
The groove can be relied on to increase the width of vertex, allow the apex angle of support arm that can will rub in the range of being located at groove in assembling
Cleaning block is installed on support arm, can reduce the assembly difficulty between support arm and brake pad.
It is preferred that the vertex of the support arm sets chamfering.Chamfered is carried out on support arm, is made sharp on support arm
Sharp apex angle disappears, and avoids install failure caused by propping up inner wall of the hole installing due to support arm apex angle in assembling process.
It is preferred that the cross section of the support arm is rectangle, the mounting hole is the hole of rectangle.
It is preferred that the swinging mounting, in cross and including four support arms, the friction mechanism includes four
The brake pad.

Specific embodiment
Description is made to the preferred embodiment of the utility model with reference to the Figure of description provided.
With reference to shown in Fig. 1 to Fig. 4, the utility model provides a kind of brake pad mounting structure, is arranged at ramp-down device
In friction mechanism 1, when the rotating member that ramp-down device mid-game is wound with steel wire rope rotates, friction mechanism 1, which applies rotating member, to rub
Resistance, so as to limit the speed of the rotating speed of rotating member and steel wire rope.Where the concrete structure of ramp-down device is not the focus of this case,
It is not described.
Friction mechanism 1 includes swinging mounting 11, transmission shaft 12 and brake pad 13, swinging mounting 11 to be fixed with transmission shaft 12,
Transmission shaft 12 is connected by the transmission component in ramp-down device with rotating member, and transmission shaft 12 can be driven when rotating member rotates, from
And rotate swinging mounting 11.Swinging mounting 11 include cross section be polygon support arm 14, brake pad 13 open up shape with
14 corresponding mounting hole 131 of support arm is simultaneously slidably socketed on support arm 14, brake pad 13 can on support arm 14 inwardly or to
Outer slip.Specifically, in cross and including four support arms 14, friction mechanism 1 includes swinging mounting 11 in the present embodiment
Four brake pads 13, four brake pads 13 are slidingly arranged at respectively on four support arms 14.Support arm 14 is that cross section is square
The structure of shape, therefore it is also the hole of rectangle that mounting hole 131 is corresponding.
The groove 132 of invagination is set respectively in four vertex of mounting hole 131, by setting the groove 132 can be apparent
Increase the width of 131 vertex of mounting hole, allow the apex angle of support arm 14 that can will rub in the range of being located at groove 132 in assembling
Cleaning block 13 is installed on support arm 14, can reduce the assembly difficulty between support arm 14 and brake pad 13.
It is preferred that with reference to Fig. 5, further to reduce assembly difficulty, can chamfering 141 be set in the vertex of support arm 14,
The cross-sectional shape of support arm 14 is rectangle, then is respectively arranged with chamfering 141 in four vertex of support arm 14.
Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art
Understand and implement according to this, the interest field of the utility model cannot be limited with this certainly, thus it is special according to the present utility model application
The equivalent variations that sharp scope is made still fall within the scope that the utility model is covered.
