Description

Elevator car bottom deformation detection device

Technical Field

The utility model relates to an elevator technical field especially relates to a deformation detection device at bottom of elevator sedan-chair.

Background

The car is a box-shaped space used by elevators to carry and transport people and materials. The elevator car is generally composed of main components such as a car bottom, a car wall, a car roof, a car door and the like, and is a car body component for carrying passengers, goods and other loads. With the popularization and application of elevators, the safety of elevators is more and more emphasized. Freight elevators, due to the need to carry heavy loads. When taking place following two kinds of circumstances, make elevator sedan-chair bottom serious deformation easily and local collapse, influence safety, the first kind: when the cargo exceeds the design load; and the second method comprises the following steps: when goods are placed more intensively, large stress is easily generated on the local part of the elevator car bottom, so that the car bottom deformation detection device is required to be designed, the deformation and the collapse of the car bottom can be detected in time, and serious safety accidents are avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 2, an elevator car bottom deformation detection device comprises an elevator car bottom 6, wherein a fixing support 2 is fixedly arranged at the bottom of the elevator car bottom 6, and the fixing support 2 plays a supporting role for the elevator car bottom 6 and is convenient for installation of a normally closed micro detection switch 4; the elevator safety detection device is characterized in that a plurality of normally closed micro detection switches 4 are arranged at the bottom of the fixed support 2, the normally closed micro detection switches 4 are uniformly distributed, the normally closed micro detection switches 4 are connected in series through connecting wires 5, the connecting wires 5 are connected with an elevator safety detection loop 7, and when the elevator car bottom 6 is deformed or collapsed due to overlarge bearing capacity, the normally closed micro detection switches 4 are triggered to be opened, so that the elevator safety detection loop 7 is disconnected, and the elevator stops working; the normally closed micro detection switch 4 and the connecting wire 5 are electrically connected with an elevator safety detection loop 7.

Connecting rods 3 are arranged at two ends of the fixed support 2, and the fixed support 2 is fixedly connected with the elevator car bottom 6 through locking bolts 1 on the connecting rods 3, so that the heights of the elevator car bottom 6 and the normally closed micro-motion detection switch 4 can be conveniently adjusted at any time.

The length of the fixed support 2 is consistent with that of the elevator car bottom 6, and the straight line of the fixed support 2 in the length direction is parallel to that of the elevator car bottom 6 in the length direction.

The top end of the normally closed micro detection switch 4 is fixedly connected with the connecting rod 3 through a hexagon nut.

The normally closed micro-detecting switches 4 are specifically arranged in three numbers, one of the normally closed micro-detecting switches is located in the middle of the bottom of the connecting rod 3, and the other two normally closed micro-detecting switches are symmetrically arranged about the center line of the elevator car bottom 6 in the length direction.

The utility model discloses a theory of operation: a plurality of normally closed micro-motion detection switches 4 are located at the bottom of the connecting rod 3 and are connected in series with each other through connecting wires 5, when the elevator car bottom 6 is deformed or collapsed due to overlarge bearing, the normally closed micro-motion detection switches 4 are punished, the normally closed micro-motion detection switches 4 are opened, the connecting wires 5 are disconnected with an elevator safety detection loop 7, and therefore the elevator stops running until maintenance personnel get rid of faults, and the elevator is recovered to be normally used.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
