Abstract
The utility model relates to an elevator goes upward overspeed hydraulic pressure system rope device, including a pair of brake block, fixed brake block is fixed on the support, and the activity brake block is connected with a hydraulic cylinder piston, and the start-up of hydraulic pump is controlled by overspeed governor wire rope. The hydraulic brake mechanism is adopted, so that the brake pressure of the traction steel wire rope is controllable, and the brake is safe and reliable. The method is suitable for overspeed protection of the traction elevator.
Description
1, technical field
The utility model belongs to a kind of towed elevator overspeed protection device, particularly a kind of ascending for elevator hypervelocity hydraulic pressure rope making device.
2, background technology
At present; in the towed elevator overspeed protection device; be provided with length of spring compressed and discharge and drive cam and the action of follower driving brake shoes; introduced " a kind of spring device that drives the elevator brake brake shoes " in the patent 200420082647; comprise a pair of brake shoes, drive the brake shoes action cam and follower, spring and latch hook spiral; spiral spring profile by latch hook control is a rectangle or cylindrical, and the cross section of spring steel is a rectangle.The spring that spirals and form by spring steel by the square-section, reach identical releasing effect, the square-section spring that spirals can be realized with less height, in use, because the limitation of spring pressure can not exceed the speed limit by actv. control ascending for elevator, causes elevator to cause the accident of rushing to summit because of hypervelocity, in construction and application process, its debugging and maintenance difficult.
3, summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of elevator overspeed brake equipment, and it is simple in structure, reliable operation.
The technical scheme in the invention for solving the technical problem is: comprise a pair of brake shoes, fixedly brake shoes is fixed on the support, and movable brake shoes is connected with a hydraulic cylinder piston, and the startup of Hydraulic Pump is to be controlled by speed limiter wire rope.
The beneficial effects of the utility model are simple in structure, adopt hydraulic brake mechanism, make the traction steel-cable brake-pressure controlled, and brake safe is reliable.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure is a kind of ascending for elevator hypervelocity hydraulic pressure rope making device scheme drawing
Among the figure: 1. fixing brake shoes 2. movable brake shoes 3. traction steel-cables 4. piston rods 5. hydraulic efficiency pressure systems 6. supports
5, the specific embodiment
The specific embodiment:
In the drawings, fixedly brake shoes (1) is fixed on the support (6), movable brake shoes (2) is fixed on the piston rod (4), when ascending for elevator motor velocity limiter detects hypervelocity, by speed limiter wire rope control source switch, primer fluid pressing system (5), the hydraulic oil of certain pressure promote piston, the close fixedly brake shoes (1) of piston rod drive activity brake shoes (2), traction steel-cable (3) is produced gripping power, reach the braking purpose.
Claims (2)
1, a kind of ascending for elevator hypervelocity hydraulic pressure rope making device comprises fixedly brake shoes and movable brake shoes, it is characterized in that described fixedly brake shoes is fixed on the support, and described movable brake shoes is fixed on the hydraulic cylinder piston.
2, according to a kind of ascending for elevator hypervelocity hydraulic pressure rope making device described in the claim 1, the startup that it is characterized in that Hydraulic Pump is to be controlled by speed limiter wire rope.
