Abstract
The utility model relates to an elevator guard device, in particular to an elevator shock-absorbing safety guard device. The elevator shock-absorbing safety guard device comprises an elevator car body, a first air bag, second air bags, third air bags, a shock-absorbing spring assembly, an acceleration sensor assembly and a lower cover plate, wherein the first air bag is mounted at a top cover plate of the elevator car body; the second air bags are arranged around the car wall of the elevator car body; the lower cover plate is arranged on the elevator car body near a base plate; the shock-absorbing spring assembly and the acceleration sensor assembly are arranged between the elevator car body and the lower cover plate; and the third air bags are arranged in the lower cover plate. The elevator shock-absorbing safety guard device provided by the utility model aims to enhance the safety of an elevator and has the advantage of simple structure and strong buffering and absorbing ability; the acceleration sensor assembly mounted at the bottom of the elevator car monitors whether the elevator is normal or not; and once the elevator breaks down, the shock-absorbing spring assembly works to absorb energy, and the air bags protect the safety of persons in the elevator car.
Description
Technical field
The utility model relates to a kind of elevator protective device, relates in particular to a kind of elevator damping safety device.
Background technology
At present, elevator is extensive use of in skyscraper, and the safety of elevator also more and more comes into one's own.General elevator all is equipped with brake gear, and brake gear can be monitored the falling speed of elevator.When elevator breaks down, when falling speed surpasses 1.3 times of normal descending speed, the control mechanism of brake gear will cut off the power supply of elevator cage to decommission.After if cut off the electricity supply, when falling speed still surpassed 1.4 times of descending speed, control mechanism started brake gear to stop elevator.
Even yet the brake gear of elevator start, the speed that elevator falls reduces because the reducing rapidly of elevator descending speed, acceleration/accel is still bigger, the people of elevator the inside still can bear the huge pressure that the elevator bottom is transmitted.If the personnel of elevator the inside do not have awareness of safety, stance mal when brake still can cause position such as lumbar vertebrae injured.When elevator brakes, also can make the elevator vibrations.The personnel's astasia that causes the inside.When elevator breaks down; the passenger of the inside is very easy to occur panic psychology; what hope can have protect self to increase the sense of security; it not is directly to cause because of elevator faults that a lot of elevator safety accidents is arranged; but because trapped personnel heart fear has taked improper measure to cause other safety misadventure.At present, also there is not corresponding protective device in the elevator.
The utility model content
Above-mentioned shortcoming that the utility model provides the customer service of a kind of elevator damping safety device, a kind of cage lifter car damping safety device is provided, when Lift out of order, make the passenger's body of the inside can disperse to bear pressure, reduce injured probability or property damage, improve the elevator safety shock absorption device of the safety performance of elevator.
The utility model adopts following technical scheme:
A kind of elevator damping safety device comprises the lift car body, first air bag, second air bag, the 3rd air bag, damping spring group, groups of acceleration sensors, lower cover; First air bag is installed at the lamina tecti place of described lift car body, second air bag is arranged in around the sedan-chair wall of lift car body, arrange lower cover at the lift car body near the base plate place, arrange damping spring group and groups of acceleration sensors between lift car body and the lower cover, arrange the 3rd air bag in the lower cover.
Elevator damping safety device described in the utility model, described lower cover is the damping alloy sheets.
Elevator damping safety device described in the utility model, described damping spring group be that rigidity is connected between lower cover adds.
Elevator damping safety device described in the utility model is characterized in that: described accelerator sensor group is made of 3 or 5 accelerator sensors.
Beneficial effect
The purpose of this utility model is to strengthen elevator safety; a kind of simple in structure, strong damping safety device of buffering absorption power is provided; whether the groups of acceleration sensors monitoring elevator that is installed in the lift car bottom occurs unusually; the elevator damping spring group work of in a single day breaking down; absorb energy, personal security in the air bag protection car.
Description of drawings
Fig. 1 is the utility model structural representation;
1 is the lift car body among the figure, and 2 is first air bags, and 3 is second air bags, and 4 is the 3rd air bags, the 5th, and damping spring group, the 6th, groups of acceleration sensors, the 7th, lower cover.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: a kind of elevator damping safety device comprises lift car body 1, the first air bag 2, the second air bags 3, the three air bags 4, damping spring group 5, groups of acceleration sensors 6, lower cover 7.
Install first air bag, 2, the second air bags 3 and arrange second air bag 3 around being arranged in the sedan-chair wall of lift car body 1 at the lamina tecti place of lift car body 1.Arrange lower cover 7 at lift car body 1 near the base plate place, arrange damping spring group 5 and groups of acceleration sensors 6 between lift car body 1 and lift car body 1 base plate, arrange the 3rd air bag 4 in the lower cover 7.Described lower cover 6 is damping alloy sheets.
Elevator is under normal operation, and the spring in the spring shock absorption group is in compressive state, is rigidly connected by the spring housing in the spring shock absorption group between damping alloy sheets and the lower steel plate.
Work as Lift out of order, abnormal tenesmus appears, groups of acceleration sensors obtains the acceleration/accel of lift car, finally determine it is the time by information fusion near the movement of falling object, spring in the spring shock absorption group is opened the working buffer state that is in immediately, and being connected no longer between lower steel plate and the damping alloy sheets is rigidly connected.Groups of acceleration sensors is generally become by 3-5 groups of acceleration sensors, and it specifically is installed in the wall of car bottom or top or car side, and it has the information fusion function, has high sensitivity and fault detection capability.
Be provided with several safety air bags in the buffering alloy sheets of the bottom of lift car, all around wall and everywhere, top are provided with a safety air bag at least at elevator.The damping alloy sheets is a kind of buffering alloy sheets of inner filled and process aluminium, and this buffering alloy sheets is simple in structure, and processing and manufacturing is easy, cost is low, and the buffering absorption power is strong.
