Downside, be respectively equipped with the first positioning plate 22 and the second positioning plate 23 on the first semi-brake watt 11 and the second semi-brake watt 12,
One positioning plate 22 and the second positioning plate 23 are fixedly connected with the first semi-brake watt 11 and the second semi-brake watt 12 respectively, the first positioning
The top and bottom of plate 22 are fixedly installed with the first telescopic rod 24 and the second telescopic rod 25 respectively, and the first telescopic rod 24 and second stretch
The end of contracting bar 25 is slidably mounted in first sliding groove 20, and the lower end and upper end of the second positioning plate 23 are fixedly installed with respectively
The end of three telescopic rods 26 and the 4th telescopic rod 27, third telescopic rod 26 and the 4th telescopic rod 27 is slidably mounted on second sliding slot
In 21, enable the first semi-brake watt 11 and the second semi-brake watt 12 with the swing of the first brake arm 2 and the second brake arm 3
And it leaves or close to braked wheel, constitutes the first semi-brake watt 11 and the second semi-brake watt 12 declutches simultaneously with brake scotch 4 and band-type brake
Structure.
When the utility model is used, brake need to be installed on the brake wheel, after brake is placed on main machine base,
Foundation bolt is screwed on, rotating rod 6, the nut on brake scotch 4, on the first semi-brake watt 11 and the second semi-brake watt 12 is answered at this time
It is elastic appropriate, it is bonded brake two sides brake scotch 4 with braked wheel, it is bad if fitted, continue rotating rod 6, when brake scotch 4
It stops rotating when being bonded with braking wheel surface and reach optimum state, then tightens foundation bolt.
When energized, electro hydraulicthruster acts, and push rod 18 rises rapidly, and makes the first system by the effect of lever 5
Swing arm 2 and the inwardly rotation of the second brake arm 3 so that the first brake scotch 4 by the first spring 14 elastic force top on the brake wheel, together
When 18 skelagia wedge block 17 of push rod slide to the left so that wedge block 17 moves up a certain distance, then wedge block 17
By expansion plate 15 drive the second semi-brake watt 12 move up so that the second semi-brake watt 12 top on the brake wheel, i.e., so that
Brake scotch 4, the first semi-brake watt 11 and the second semi-brake watt 12 close up (band-type brake), and when power is off, electro hydraulicthruster pushes away
Bar 18 under spring force, declines rapidly, then the first semi-brake watt 11 with the first brake arm 2 and the second brake arm 3 from
Braked wheel is opened, and expansion plate 15 drives the second semi-brake watt 12 to leave braked wheel, i.e. brake scotch under the action of second spring 19
4, the first semi-brake watt 11 and the second semi-brake watt 12 open (declutching).
Inspect periodically the working condition of brake.It should focus on the following terms when inspection:
A, whether the component movement of brake normally fasten.
B, whether the work of pusher is normal, and whether hydraulic oil is enough, and whether there is or not oil leaks and permeability phenomenon, introduces the exhausted of electric wire
Whether edge is good.
C, whether brake scotch 4 normally leans on the brake wheel, and whether the state of friction surface is intact, and it is existing that whether there is or not greasy booties
As.When the thickness of brake rim reaches certain numerical value, then Ying Genghuan.
D, the temperature of braked wheel is no more than 200 DEG C.
If e, lever 5 and spring find seminess, should replace immediately.
The beneficial effects of the utility model are: power hydraulic pressure block brake open in usual can be used for lifting, transport, metallurgy,
The mechanical braking of the mechanical actuation devices such as mine, harbour, building.With brake steady, safe and reliable, easy to maintenance, little power consumption,
The features such as service life is long, noiseless.Its number of operations per hour up to 720 times, and can the surrounding to braked wheel brake,
Braking effect is splendid.
