Abstract
The invention discloses a device for preventing a lift car from moving by accident. The device comprises the lift car located in a shaft. One fixing plate (2) is arranged on each floor in the shaft. Each fixing plate (2) is provided with a transverse penetrating hole (21). The lift car (5) is further provided with locking pieces (3) capable of moving transversely to be inserted into the penetrating holes (21) in the corresponding fixing plates (2) and drive devices (4) for driving the locking pieces (3). Compared with the prior art, the locking pieces on the lift car are matched with the penetrating holes in the fixing plates on all the floors in the shaft in a penetrating manner, the lift car is prevented from moving by accident, the structure is simpler, working is more reliable, and use is safer.
Description
Technical field
The present invention relates to and a kind ofly prevent the involuntary mobile device of car for cage lifter system.
Background technology
When the cage operation of cage lifter is come in and gone out for passenger to level position, must relative static conditions be kept, prevent the involuntary movement of car from causing safety misadventure.Prevent the involuntary mobile device of lift car from being all generally that mechanism by being arranged on towing machine part realizes in prior art, such as Chinese invention patent CN103274275, disclosed in it, a kind of involuntary mobile device of lift car that prevents adopts the cooperation of movable clamping block and folding clamp to clamp hoist ropes, prevent the involuntary movement of car, its complicated structure, trouble is installed, and may occurs slipping the situation of restricting because of insufficient clamping force, not reliably.
Summary of the invention
In view of this, the object of this invention is to provide that a kind of structure is simpler, work is more reliable, use and safer prevent the involuntary mobile device of car.
For achieving the above object, the invention provides one and prevent the involuntary mobile device of car, comprise the car being arranged in hoistway, it is characterized in that: every layer of level position in described hoistway is all separately installed with an adapter plate, each described adapter plate offers the perforation laterally run through, described car is also provided with can cross motion to insert the locking piece of the described perforation in adapter plate described in one of them and to drive the actuating device of described locking piece.
Wherein, described perforation is strip hole, and its length direction extends longitudinally.The design of strip hole, after locking piece is inserted in the hole, can meet elevator again flat bed time car experiencing small oscillating movements in the vertical requirement.
Preferably, described locking piece is anchor shaft, and it is arranged along self axial cross motion.
In one embodiment, described actuating device is motor.During Elevator landing, give described feeding electric motors by communication signal or electric signal, thus drive locking piece motion, penetrate in the perforation of adapter plate, prevent the involuntary movement of car.
Wherein, each described adapter plate is fixed on the sidewall of described hoistway respectively by support.
This prevents the involuntary mobile device of car from also comprising the guide rail of longitudinal extension setting, and each described adapter plate is separately fixed on described guide rail.
Compared to prior art, the present invention adopts the perforation on the adapter plate of the locking piece on car and each level position to carry out interting cooperation, prevents the effect of car involuntary movement when reaching Elevator landing, and structure is simpler, and work is more reliable, uses safer.And in further improving, by the perforated design growth bar shaped on adapter plate, can meet elevator again flat bed time car upper and lower experiencing small oscillating movements requirement.
Accompanying drawing explanation
Fig. 1 is that the present invention prevents the structural representation of the involuntary mobile device of car when elevator operation.
Fig. 2 is that the present invention prevents the structural representation of the involuntary mobile device of car when Elevator landing state.
Fig. 3 is the structural representation of the adapter plate in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to Fig. 1 to 3, one prevents the involuntary mobile device of car, comprise the car 5, the longitudinal extension that are arranged in hoistway to be arranged on guide rail 1 outside car 5, to be arranged on locking piece 3 on car 5 and actuating device 4, every layer of level position in hoistway is all separately installed with an adapter plate 2, each adapter plate 2 offers the perforation 21 laterally run through.In the present embodiment, each adapter plate 2 is all directly fixed on guide rail 1, and in other embodiments, each adapter plate 2 can be fixed on the sidewall of hoistway respectively by support.
Locking piece 3 is wherein anchor shaft, and it can along self axial motion under the driving of actuating device 4.Actuating device 4 is motor.When Elevator landing, apparatus for controlling elevator gives described feeding electric motors by communication signal or electric signal, thus drive locking piece 3 along self axial motion and insert in the perforation 21 of one of them adapter plate 2, thus prevent the involuntary movement of car during Elevator landing state, as shown in Figure 2.When the elevator is run, apparatus for controlling elevator makes motor power-off by communication signal or electric signal, thus drives locking piece 3 to move along own axes and exit the perforation 21 of adapter plate 2, and car 5 can continue to run up and down, as shown in Figure 1.
Refer to Fig. 3, the perforation 21 on adapter plate 2 is strip hole, and its length direction extends longitudinally, namely parallel with the direction of car up-and-down movement.Adopt the design of strip hole, locking piece 3 inserted after in perforation 21, can meet elevator again flat bed time car 5 experiencing small oscillating movements in the vertical requirement.
As seen from the above embodiment, the involuntary mobile device of car that prevents of the present invention is coordinated with the perforation grafting of adapter plate by locking piece, the object of car involuntary movement is prevented when reaching Elevator landing, and perforation adopts the design of strip hole can also meet the requirement of elevator flat bed again, integral structure is simple, easy for installation, use more reliable and safety.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
