Abstract
The utility model discloses a lift car falling safety device for a car lift. The lift car falling safety device comprises a small-sized hydraulic power pack, a high-pressure hose, a plunger cylinder, a plunger rod, a fixing mother board, a safety contact switch and an automatic reset travel switch. The small-sized hydraulic power pack is connected to the upper end of the plunger cylinder through the high-pressure hose. The plunger rod is installed at the left end of the plunger cylinder. The fixing mother board and the automatic reset travel switch are connected and then arranged at the front end of the plunger rod. By means of the way, according to the lift car falling safety device, a lift control system controls the small-sized hydraulic power pack to work, and the plunger cylinder pushes the plunger rod out and the plunger rod is inserted into a mother board through hole of the fixing mother board. When a car enters or leaves a lift car, due to the fact that stress on the edge of a car lift doorway is centralized, the lift car falling safety device is used for preventing unforeseen circumstances caused by the fact that guide shoes break or sinking of the lift car exceeds the stretching-out and drawing-back amount of a steel wire rope, and ensuring absolute safety of transporting car equipment and personnel inside the car.
Description
Technical field
The utility model relates to the elevator field, particularly relates to dropping safety device under a kind of car of car elevator, and this device mainly uses at car elevator and super-tonnage cargo lift.
Background technology
Raising along with people's living standard, with society the requirement of quality of the life is improved constantly, the people who has automobile is more and more, and the people who has private villa and automobile is a lot of equally, in order to allow automobile can be parked in assigned address, need automobile to be parked on the roof platform as the somebody, car elevator has just become the transportation means of necessary use so, and the most scabrous problem of car elevator is exactly when automobile is come in and gone out car, it is unexpected that sinking can appear in one of car terrace, both cage guide, fixedly body of wall, lead boots and impact, equally also have security risk.
The utility model content
The technical matters that the utility model mainly solves provides dropping safety device under a kind of car of car elevator, solved when automobile is come in and gone out car in the prior art, it is unexpected that sinking can appear in one of car terrace, both cage guide, fixedly body of wall, lead the problem that boots impact.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: dropping safety device under a kind of car of car elevator is provided, comprise small-sized hydraulic pumping plant, high pressure hose, plunger case, plunger rod, fixedly motherboard, safety contact switch and the travel switch that automatically resets, described small-sized hydraulic pumping plant is connected the upper end of plunger case by high pressure hose, described plunger rod is installed in the left end of plunger case, described fixedly motherboard and the front end that is placed on plunger rod after the travel switch that automatically resets is connected.
In preferred embodiment of the utility model, described fixedly motherboard also is provided with a motherboard through hole, and described motherboard through hole matches with the top of plunger rod.
In preferred embodiment of the utility model, an end of described safety contact switch is installed on the plunger case, and the other end is installed on the plunger rod.
In preferred embodiment of the utility model, described plunger rod is stretching structure.
In preferred embodiment of the utility model, when described plunger rod was extended, the safety contact switch disconnected; When described plunger rod shortens, the safety contact switch connection.
The beneficial effects of the utility model are: dropping safety device under the car of the car elevator that the utility model provides, carry out work by apparatus for controlling elevator control small-sized hydraulic pumping plant, plunger case is released plunger rod and is inserted in the motherboard through hole of fixing motherboard, when automobile enters car or leaves car, because edge, car elevator doorway is stressed more concentrated, be used for preventing sinking to exceeding unforeseen circumstances due to the steel rope stroke owing to lead boots fracture or car self, guarantee being perfectly safe of the automobile equipment that transports and occupant.
Description of drawings
Fig. 1 is the structural representation of dropping safety device one preferred embodiment under the car of car elevator of the present utility model;
The mark of each parts is as follows in the accompanying drawing: 1, small-sized hydraulic pumping plant, 2, high pressure hose, 3, plunger case, 4, plunger rod, 5, fixing motherboard, 6 safety contact switches, 7 travel switches that automatically reset, 51, the motherboard through hole.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model provides dropping safety device under a kind of car of car elevator, comprise small-sized hydraulic pumping plant 1, high pressure hose 2, plunger case 3, plunger rod 4, fixedly motherboard 5, safety contact switch 6 and the travel switch 7 that automatically resets, described small-sized hydraulic pumping plant 1 is connected the upper end of plunger case 3 by high pressure hose 2, described plunger rod 4 is installed in the left end of plunger case 3, described fixedly motherboard 5 and the front end that is placed on plunger rod 4 after the travel switch 7 that automatically resets is connected.Wherein, an end of described safety contact switch 6 is installed on the plunger case 3, and the other end is installed on the plunger rod 4.
In above-mentioned, described fixedly motherboard 5 also is provided with a motherboard through hole 51, and described motherboard through hole 51 matches with the top of plunger rod 4.
Wherein, described small-sized hydraulic pumping plant 1 is fixed on bottom, car elevator car doorway; Fixedly motherboard 5 is fixed on the well enclosure of landing sill downside.
When elevator stops layer, after small-sized hydraulic pumping plant 1 is received the signal of apparatus for controlling elevator, send oil by high pressure hose 2 toward plunger case 3 rear sides, promote plunger rod 4 and move, enter in the motherboard through hole 51 of fixing motherboard 5.
After elevator is finished handling labor, apparatus for controlling elevator is given small-sized hydraulic pumping plant 1 signal, small-sized hydraulic pumping plant 1 is by the anterior oiling of high pressure hose 2 toward plunger case 3, plunger rod 4 begins to shrink, after get back to reference position, plunger rod 4 was left the travel switch 7 that automatically resets, the switch electrical contact automatically reset, when plunger rod 4 was got back to reference position, safety contact switch 6 was connected.
Dropping safety device under the car of the car elevator that the utility model provides has realized that the car elevator car that will stop is locked at level position with mechanical part, when car elevator starts, realizes safe release.Simultaneously, realize the electric verification step synchronous with mechanical part by safety contact switch 6 and the travel switch 7 that automatically resets, guaranteed the safety of system.
Dropping safety device under the car of the car elevator that the utility model discloses, carry out work by apparatus for controlling elevator control small-sized hydraulic pumping plant, plunger case is released plunger rod and is inserted in the motherboard through hole of fixing motherboard, when automobile enters car or leaves car, because edge, car elevator doorway is stressed more concentrated, be used for preventing sinking to exceeding unforeseen circumstances due to the steel rope stroke owing to lead boots fracture or car self, guarantee being perfectly safe of the automobile equipment that transports and occupant.
