The existing steel wire braking in market comprises the voussoir pinch brake at present, also comprises the brake facing underframe of drg and the forward and backward backing plate assembly that side plate fixedly is provided with between the frame plate, and the needle roller of placing respectively between the forward and backward backing plate assembly is secondary; The brakeage bar is connected with the shake-up plate.When ascending for elevator was rushed to summit, voussoir pinch brake by gravity moved down and clamps steel rope.It is the milestone that part concerns human life that ascending for elevator is rushed to summit; Must in the shortest time, prevent; Yet the voussoir pinch brake under slide into and clamp steel rope and need a period of time, long more during this period of time, just more dangerous in the car (casing); Therefore, braking time how to accelerate the voussoir pinch brake has been put on people and has been studied schedule.
Summary of the invention
In order to address the above problem, but the utility model provides a kind of lift car protection device for over-speed ascending of snap catch rational in infrastructure.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of lift car protection device for over-speed ascending; Comprise base and the wedge shape slipper that is installed in the base; Base is made up of adapter plate, left and right side plate and baffle plate; The wedge shape slipper is arranged in order by rope clamping plate, sliding clamping plate and left and right wedge block and forms, and is provided with touch device between said wedge shape slipper and the base, and the rope clamping plate that faces adapter plate is provided with the deep-slotted chip breaker relative with steel rope.
In the utility model, the side of said left and right wedge block is provided with tongue, and left and right side plate is provided with and the corresponding positioning groove of tongue.
In the utility model, be connected with spring between said wedge shape slipper and the base, spring distributes along the direction that the wedge shape slipper moves.
In the utility model, said touch device comprises the throw rod that is installed on the wedge shape slipper and is installed in the release arm on the base, and release arm blocks throw rod, and release arm is connected with an electric switch.
In the utility model, the outside face of said left and right wedge block is provided with guide rail, and guide rail is provided with needle roller slide plate piece, but needle roller slide plate piece is provided with several free rolling needle rollers.
The beneficial effect of the utility model is: the utility model is provided with the deep-slotted chip breaker relative with steel rope on rope clamping plate, increases the frictional area of rope clamping plate and steel rope, increases friction force, accelerates the speed that the wedge shape slipper moves down, and reaches the effect of faster braking; Further, between wedge shape slipper and base, be connected with spring, spring distributes along the direction that the wedge shape slipper moves, and further accelerates the speed that the wedge shape slipper moves down through the elastic force of spring; The wedge shape slipper of the utility model moves down rapidly and clamps steel rope under the effect of the pulling force of the friction force of self gravitation, steel rope and rope clamping plate and spring, thereby reaches the effect of snap catch, ensures personage's in the car safety.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of present embodiment.
The specific embodiment
With reference to Fig. 1; But the lift car protection device for over-speed ascending of a kind of snap catch rational in infrastructure that the utility model provided; Comprise base 1 and the wedge shape slipper 2 that is installed in the base 1, base 1 is made up of adapter plate 11, left and right side plate 12,13 and baffle plate 14, and wedge shape slipper 2 is arranged in order by rope clamping plate 21, sliding clamping plate 22 and left and right wedge block 23,24 and forms; Be provided with touch device 3 between said wedge shape slipper 2 and the base 1; The rope clamping plate 21 that faces adapter plate 11 is provided with several deep-slotted chip breakers 211 relative with steel rope, increases the frictional area of rope clamping plate 21 and steel rope, increases friction force; Accelerate the speed that wedge shape slipper 2 moves down, reach the effect of faster braking
As preferred embodiment; The side of said left and right wedge block 23,24 is provided with tongue 25; Left and right side plate 12,13 is provided with and tongue 25 corresponding positioning grooves 15; Reduce left and right wedge block 23,24 and left and right side plate 12, the gap between 13, can not swing, make sliding of wedge shape slipper 2 more smooth.
Further, be connected with spring between said wedge shape slipper 2 and the base 1, spring distributes along the direction that wedge shape slipper 2 moves.At left and right wedge block 23, be provided with middle slide block between 24, middle slide block is provided with Spring screws, an end of spring is installed on the Spring screws, the bottom of other end mounting seat 1.After touch device 3 unclamps wedge shape slipper 2; Wedge shape slipper 2 is under the effect of the pulling force of the friction force of self gravitation, steel rope and rope clamping plate 21 and spring; Move down rapidly and clamp steel rope, thereby reach the effect of snap catch, ensure personage's in the car safety.
