Suspension device of elevator compensation chain with cleaning function

technical field

The invention relates to the technical field of compensation chain suspension, in particular to a suspension device for an elevator compensation chain with a cleaning function.

Background technique

It is used to connect the elevator car and the counterweight, balance the weight of the traction rope and the accompanying cable, and play a balancing role in the operation of the elevator. During the operation of the elevator, the length of the steel wire rope on the side of the car and the side of the counterweight is constantly changing. , resulting in changes in the weight of the wire ropes on both sides of the traction sheave. When the car is at the bottom station, most of the weight of the wire rope acts on the side of the car; when the car is at the top floor, most of the weight of the wire rope acts on the counterweight side. This change has little effect on the operating performance of the elevator when the lifting height of the elevator is not large, but when the lifting height exceeds a certain height, it will seriously affect the stability of the elevator operation and endanger the safety of passengers and property. When the lifting height exceeds a certain height, it is necessary to install components with a certain weight to balance the balance weight change caused by the height change, so the compensation chain (rope) of the elevator came into being, and the compensation chain is connected to the car , it is necessary to use a suspension device to complete the connection between the compensation chain and the bottom side of the car.

7. The method of using a suspension device for an elevator compensation chain with cleaning function according to claim 6, characterized in that the working steps of the suspension device are as follows:

s1, when a compensation chain is hung on a hanging hook (1), the compensation chain penetrates out of the top side of an air injection plate (8) from the bottom side of the air injection plate (8), so that the compensation chain is surrounded by an air injection hole (9), when an elevator is in operation, the elevator is lifted, the compensation chain moves in the air injection plate (8) along with the lifting, at the moment, an air pump (11) injects external air into the air injection plate (8) through a connecting pipe (12), air flow is sprayed onto the compensation chain from the air injection hole (9), and therefore the compensation chain is flushed by the air flow, dust and impurities attached to the outer wall of the compensation chain are blown away, bending of the compensation chain due to the fact that dust accumulation is not cleaned for the time of the compensation chain length is avoided, and the use effect of the compensation chain is improved;

s2, when the hanging hook (1) is screwed and fastened, the pressing plate (16) is screwed and embedded into the groove (14) along with the screwing, the pressing plate (16) presses the trigger block (18), the trigger block (18) moves to enable the pull rope (19) to be loosened, the third spring (22) with tensile storage force pulls the touch plate (23) to move, the touch plate (23) is pressed on the top of the pressure sensor (21), when the hanging device is loosened, the bottom plate (2) of the hanging device is loosened, the pressing plate (16) protrudes out of the groove (14), the second spring (17) ejects the trigger block (18), the trigger block (18) pulls the touch plate (23) to move through the pull rope (19), the touch plate (23) moves upwards and is not contacted with the pressure sensor (21), and at the moment, the pressure sensor (21) does not detect the pressure exerted by the touch plate (23), the alarm (13) is sounded, and therefore the problem of fixing and loosening of the hanging device can be quickly found;

s3, a temperature sensor (25) is positioned on the top side of a contact point of the suspension hook (1) and the compensation chain, when the suspension point of the suspension hook (1) is increased in temperature due to shaking friction of the compensation chain when the suspension hook (1) and the compensation chain are less in lubricating oil, a motor (29) rotates to drive a gear (30) to rotate, the gear (30) rotates to drive a toothed plate (28) to move, the toothed plate (28) moves to drive a piston (27) to move, and the piston (27) moves to guide the lubricating oil to the suspension point of the suspension hook (1) through a flow pipe (31), so that the contact part of the suspension hook (1) and the compensation chain is lubricated, abrasion between the suspension hook (1) and the compensation chain is reduced, and the service life of the suspension hook (1) is prolonged;

s4, one end of a steel wire rope (37) of the spring is directly fixed at the bottom of the bottom plate (2), when a compensation chain is hung, the embedded block (38) penetrates through the compensation chain, the embedded block (38) is inserted into the embedded groove (36), the pulling plate (34) is loosened, the pulling plate (34) is restored by the spring (33) IV, the clamping rod (35) is inserted into a clamping hole of the embedded block (38), and accordingly the steel wire rope (37) is fixed.

8. The method of using a suspension device for an elevator compensation chain with cleaning function according to claim 7, characterized in that in said step S1, it further comprises the steps of:

s11, an air jet plate (8) of the elevator car extends to one side of the outer wall of the elevator car, so that the compensating chain penetrates through the air jet plate (8) and is in a natural falling state;

in the step S2, the method further includes the following steps:

s21, the elastic force applied by the spring II (17) to the trigger block (18) is larger than the tensile force applied by the spring III (22) to the touch plate (23);

in the step S4, the method further includes the following steps:

s41, the steel wire rope (37) is attached to the outer wall of the bottom side of the hanging hook (1), so that the steel wire rope (37) does not affect the compensation chain when not used.
