Description
Technical field
The present invention relates to a kind of deadman's brake, specifically a kind of rope brake.
Background technique
For the pernicious personnel casualty accidents for preventing carriage accidental movement from generating, the safety that elevator uses is improved, meets electricity
The safety standard requirement that ladder is installed and used, applicant proposed a kind of the new of wedge-shaped rope brake that can be used as elevator safety brake
Design.The structure of this wedge shape rope brake is to be provided with two opposite braking fixture blocks of sandwich serface, two brake clips in the frame
Form rope channel between the sandwich serface of block, in two braking fixture blocks, at least one is the work that can be moved up and down in the frame
Dynamic fixture block.Movable clip block is wedge block, and the inner edge of the rack to fit with the lozenges of movable clip block is wedge-shaped inner groove surface, activity
Fixture block is sticked on the wedge-shaped inner groove surface of frame by tension spring.The design utilizes the cooperation of sphenoid and lozenges, can be in elevator
When accident occurs for carriage or hoisting heavy, press from both sides haulage cable rapidly by rope brake extremely, to prevent serious accident
Occur.
To implement the braking of effective rope-clamping, the weight of movable clip block is and this heavy weight with regard to relatively large in rope brake
Movable clip block, it is first larger with the frictional resistance of frame inner wall, it is unfavorable for the raising of rope brake action sensitivity；Second activity folder
Block, since the weight of movable clip block is big, is needed using pulling force by the way that the four of rack quadrangle tension spring drawing positioning are arranged in
Very big tension spring can be just pulled, and make its positioning, and use of this big pulling force tension spring in rope brake, can be directly resulted in
The reduction of rope brake action sensitivity and reliability correspondingly reduces the safety braking performance of deadman's brake.
Summary of the invention
It is an object of the invention to provide a kind of rope brakes, to solve rope brake because using big pulling force tension spring positioning activity to press from both sides
Block and the problem of rope brake action sensitivity and reliability are reduced.
The object of the present invention is achieved like this: a kind of rope brake, including rack, fixing clip, movable clip block, in fixation
It is attached with friction plate respectively on the sandwich serface of fixture block and movable clip block.
The rack includes two side plates and the end plate between two side plates, and being provided on the side plate makes to live
Dynamic fixture block keeps the first spring-loaded plunger of normality positioning, is equipped on the inner wall of the end plate and movable clip block is pushed to implement rope-clamping
The uplink motion-stopping surface and downlink motion-stopping surface of movement are provided with the rear ejection machine of ejection movable clip block rear wall on the end plate
Structure is fixed with the preceding penetrating mechanism of ejection movable clip block front end face on the front port of the rack.
The movable clip block includes fixture block ontology and friction plate；The front surface of the fixture block ontology is vertical surface, described
The back side of fixture block ontology is equipped with uplink slideway, downlink slideway and vertical plane slideway, the uplink on the uplink slideway and rack
Motion-stopping surface is opposite, and the downlink slideway is opposite with the downlink motion-stopping surface in rack, the vertical plane slideway and is mounted on rack
On it is described after penetrating mechanism it is opposite, have detent translot, first spring-loaded plunger in the two sides of the fixture block ontology
Cylinder front end be connected in the detent translot.
The bulb plunger that penetrating mechanism includes pedestal and is arranged on the pedestal after described；The ball head column is plugged at least
Two, it is not set to be adjacent to end plate for ejection movable clip block forward at longitudinal arrangement.
The preceding penetrating mechanism includes substrate, second spring plunger, bracket and penetrator ram；The second spring plunger setting
In the plate face of the substrate, the bracket is arranged on the cylinder of the second spring plunger, and the penetrator ram is arranged in institute
It states on bracket, and perpendicular with the cross central line of the substrate.
The present invention is realized by the preceding penetrating mechanism and rear penetrating mechanism of setting through type on the rack to movable clip block
Front and rear direction elastic ejection, then the accurate detent of elasticity of the spring-loaded plunger by two sides, so that movable clip block is normal
It can steadily be supported on the inner groove surface for sticking on rack under state, also, the design of original preceding penetrating mechanism, not influence also to lead
Draw wirerope from the emergency braking passed through with rope brake in rope brake rope-clamping channel, thus both eliminates making for tension spring
With in turn avoiding because the movable clip block that movable clip block weight itself is excessive, tension spring tension is not easy to determine etc. caused by reasons is in machine
It is not easy accurate positioning in frame and is easy to appear the problem of gravity sinks, and becomes fixed and positioned in rack of movable clip block
Simply and conveniently.
The present invention is respectively arranged with the sliding row of roll shaft on the uplink slideway and downlink slideway of the end plate；The roll shaft is sliding
Row is that roll shaft row is provided between the opposite clamp rail of two openings, and the roll shaft axial plane on roll shaft row is higher by the top surface of clamp rail,
Tension spring is connected between the roll shaft row and the end plate.
The present invention can make movable clip block by the way that roll shaft row is respectively set on the uplink motion-stopping surface and downlink motion-stopping surface of rack
Sliding friction in rack becomes the rolling friction that support is arranged by roll shaft, can thus substantially reduce coefficient of friction, improve and live
The dexterity of action of dynamic fixture block；The roll shaft row in slideway is connected by tension spring, roll shaft can be made, which to come in slideway, appropriate displacement, from
And impact force when adapting to and dissolving movable clip block initial actuating, neutralizing impact well is played, resistance is reduced, improves braking and ring
Answer the effect of speed.
It is provided with upper adjustment frame at the top of the rack, upright screw hole is provided on the upper adjustment frame, screw thread connects
It is connected to the upper mandril of limitation movable clip block uplink final position.
The bottom of the rack is provided with lower adjustment frame, upright screw hole is provided on the lower adjustment frame, screw thread connects
It is connected to the next mandril of limitation movable clip block downstream end position.
The present invention is by the cushion rubber bumper being arranged in fixing clip and movable clip block, it can be achieved that a degree of buffering is made
It is dynamic, herein under the premise of, by the upper mandril and the next mandril being arranged on the rack, can uplink and downlink to movable clip block it is whole
Stop bit is set to be adjusted in right amount, and gravity deceleration when thus can be to rope brake emergency braking regulates and controls, urgent to meet
Standard regulation of the gravity deceleration-based controller between 0.2-0.4g when braking, meets the standard of accident brake brake legislation
It is required that having also complied with the range that human body is able to bear, the case where injuring passenger-in-elevator because of emergency braking generation is effectively avoided.
In addition, the present invention can also by the front end face of upper adjustment frame and lower adjustment frame is cut into rope channel top and
Lower space region thus can play certain leveling to the jitter conditions for the haulage cable for passing through rope channel,
Touch movable clip block, because jitter amplitude is excessive to avoid haulage cable to cause the case where movable clip block malfunctions,
The effect for playing the anti-unusual fluctuation of rope brake has correspondinglyd increase the job stability and reliability of rope brake.
The present invention improves rope brake action sensitivity and functional reliability, improves the safety arrestment of deadman's brake
Energy.
