Description
Technical field
The utility model belongs to the safety guard-safeguard apparatus technical field of tractive driving jacking equipment, is specifically related to a kind of lift car that prevents and surprisingly moves up and down the gradual bidirectional rope gripper with up-running over-speed protection.
Background technology
At present; China does not propose clear and definite protection for the accidental movement of elevator cage operating mode of tracking-driven elevator and requires (not having relevant provision in GB788-2003 standard); cause now elevator cause, when opening layer door and Room door, lift car accidental movement up or down occurs under drg and other parts are in abnomal condition, easily cause passenger that the personal safety accident sheared occurs when passing in and out elevator door.In order to solve this safety problem, GB7588-2003 revises, on all elevators, wherein mainly force increase to prevent accidental movement of elevator cage fender guard.
For tackling this revised standard, mainly contain the version preventing accidental movement of elevator cage fender guard as follows at present:
1, the drg of redundancy is utilized, and by electrical control to prevent accidental movement of elevator cage.But this version practical function is also little, if brake lost efficacy, lift car still can produce and slowly move phenomenon, causes fender guard to lose efficacy.
2, the stop layers protection mechanism on building hoist is used for reference; namely when the cage of building hoist arrives stop; the connecting rod mechanism be connected with door can stretch out two strut bars and be supported in the hole of well enclosure when door is opened, realize stop layers protection, prevent cage accidental movement.But the structure of this kind of fender guard is comparatively simple and crude, be unfavorable for the ride comfort ensureing lift car.
3, a kind of HW wire holder disclosed in US Patent 5228540, effectively can prevent the accidental movement of lift car.But its volume is comparatively large, price is higher, and is not easy to install additional on existing operation elevator, does not meet China's national situation.
Chinese patent 2012103116617 discloses a kind of progressive rope gripper, it is adopt voussoir progressive folder rope principle to realize clamping of steel rope, its enormous impact kinetic energy that stop elevator car can be produced and potential energy change elastic potential energy into, effectively avoid the Fast Wearing of steel rope distortion or friction lining.But traction steel-cable only can be clamped by this kind of progressive rope gripper in one direction, can not meet the requirement preventing accidental movement of elevator cage fender guard from need be clamped by traction steel-cable in the two directions.
Utility model content
The purpose of this utility model is the structural principle utilizing existing progressive rope gripper, provides a kind of gradual bidirectional rope gripper, to solve the deficiencies in the prior art part.
For achieving the above object, the utility model adopts following technical scheme:
Gradual bidirectional rope gripper, comprises support body, is provided with adapter plate and corresponding described adapter plate formation wedge shape slideway in described support body; To being provided with folder rope assembly by wedge shape slideway in described support body; Described folder rope assembly is two gradual folder rope assemblies, and the corresponding described wedge shape slideway of this two gradual folder rope assembly is oppositely arranged.
Further, often organize gradual folder rope assembly to comprise: one or two energy-storaging spring mechanisms, are arranged in described support body; One uncoupling rigging, is arranged in described support body; One swash plate, to be oppositely arranged in support body with described adapter plate and to be connected with described two energy-storaging spring mechanisms; One wedge shape activity slipper, is arranged in the wedge shape slideway formed between described swash plate and adapter plate; With certain slipper, be arranged on the medial surface of described adapter plate by an Elastic Sliding assembly.
Further, described swash plate is provided with needle roller slide plate, one side and the described needle roller slide plate wipe contact of described wedge shape activity slipper.
Further, each uncoupling rigging corresponding is provided with electric flame-out switch and electromagnetic valve.
The utility model, by adopting said structure, can realize the accidental movement preventing lift car in the two directions, and can retain original over-speed protection function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-support body; 11-adapter plate; 12-wedge shape slideway; 2-two energy-storaging spring mechanisms; 3-uncoupling rigging; 4-swash plate; 41-needle roller slide plate; 5-wedge shape activity slipper; 6-determine slipper; 61-Elastic Sliding assembly; 7-electromagnetic valve; 8-electrically flame-out switch.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
Detailed description of the invention
As shown in Figure 1, gradual bidirectional rope gripper described in the utility model, comprises support body 1, is provided with adapter plate 11 and corresponding adapter plate formation wedge shape slideway 12 in support body 1, and in support body 1, corresponding wedge shape slideway oppositely arranges two groups of gradual folders rope assemblies.Often organize gradual folder rope assembly to determine slipper 6 primarily of a two energy-storaging spring mechanism 2, uncoupling rigging 3, swash plate 4, wedge shape activity slipper 5 and one and form: two energy-storaging spring mechanisms 2 are arranged in support body 1; Uncoupling rigging 3 to be arranged in support body 1 and to be connected with two energy-storaging spring mechanisms; Swash plate 4 and adapter plate 11 to be oppositely arranged in support body 1 and to be connected with two energy-storaging spring mechanisms 2, form wedge shape slideway 12 between swash plate 4 and adapter plate 11; Wedge shape activity slipper 5 is arranged in this wedge shape slideway 12; Determine slipper 6 and be arranged on (structure of this Elastic Sliding assembly 61 is with the Elastic Sliding assembly disclosed in 2012103116617) on the medial surface of described adapter plate by an Elastic Sliding assembly 61.In addition, swash plate 4 is provided with needle roller slide plate 41, one side and this needle roller slide plate 41 wipe contact of wedge shape activity slipper 5.Further, corresponding each uncoupling rigging is provided with electromagnetic valve 7 and electric flame-out switch 8.
Folder rope operating principle of the present utility model, with 2012103116617, does not repeat them here.And it should be noted that, because two groups of gradual folder rope assemblies oppositely arrange, therefore can realize the clamping in traction steel-cable both direction, thus the object of the accidental movement preventing lift car can be reached.
In addition, a flat bed inductor (distance by the given accidental movement of standard-required) can be set up in elevator door zone, to monitor car accidental movement, once be moved, give electromagnetic valve signal immediately, electromagnetic valve triggers wire holder, makes the unexpected car stop moved up or down.
Further, can utilize the electric switch of bidirectional speed limiter, when lift car reaches velocity limiter electric switch action before responsiveness up or down, give electromagnetic valve signal immediately, electromagnetic valve triggers wire holder, makes the car stop exceeded the speed limit up or down.
Further, utilize the various sensors on elevator, monitor the operational situation of elevator, faulting instruction is sent by computer control system, the electromagnetic valve of gradual bidirectional rope gripper triggers wire holder immediately, implements the braking (now, wire holder is equivalent to sure brake) to lift car.
The utility model can also utilize velocity limiter to exceed the speed limit simultaneously, pulls governor rope, and machinery triggers the wire holder of up mobile protection, makes it still have the function of up-running over-speed protection.
