Description
Technical Field
The application relates to the technical field of elevators, in particular to an elevator overhaul safety device.
Background
Elevators are used as vehicles and require maintenance and repair during their daily use. Some maintenance needs maintenance personnel to enter the elevator pit for operation, and in order to prevent the elevator from accidentally falling and causing the life safety of the maintenance personnel, a common safety measure is to arrange a buffer and a cement pier in the pit. This approach is not feasible for elevators with shallower pits. Especially for the elevator with sundries, it is inconvenient to install and design the mechanical stopping device because the space of the shaft is too small.
Disclosure of Invention
The technical scheme of the utility model is that: the utility model provides an elevator overhauls safety device, its constitution includes the guide rail and rather than swing joint's ejector pin, its characterized in that: the utility model discloses a safety elevator, including ejector pin, rotary connection board, backup pad, fixed plate and backup pad, the right side symmetry movable mounting at the upper and lower both ends of ejector pin has rotary connection board, rotary connection board's the other end and the left end swing joint of backup pad, the backup pad passes through guide rail clamp plate fixed mounting on the guide rail, the one end movable mounting that the backup pad is close to the ejector pin has rotatory locking plate, on the ejector pin still fixed mounting have with rotatory locking plate and backup pad matched with locking plate, on the guide rail still fixed mounting have the fixed plate, the one end fixed mounting that the fixed plate is close to the ejector pin has UKT automatic re-setting switch, fixed mounting has the switch beating plate.
The utility model has the advantages that:
1. the utility model discloses a swivelling joint board and backup pad are connected ejector pin and guide rail, and when opening the ejector pin, the ejector pin passes through the rotor plate and moves the right front of guide rail, and is located car bottom plate's below, can play the supporting role to the car, and the switch beater leaves UKT automatic re-setting switch this moment, and the electrical control safety circuit's of elevator power is cut off, and the elevator stop motion can effectively guarantee maintainer's safety.
2. When the ejector rod of the utility model is folded through the rotary connecting plate, the locking baffle is clamped between the rotary locking plate and the supporting plate, so that the ejector rod is fixed; at the moment, the switch beating plate is contacted with the UKT automatic reset switch, the power supply of the elevator is switched on, and the elevator can normally run; and the ejector rod is arranged on the right side of the guide rail after being retracted, so that the normal operation of the elevator is not influenced, and the space is also saved.
3. The utility model discloses simple structure, simple to operate, the security is also higher, does benefit to and uses widely.
Drawings
Fig. 1 is a schematic structural diagram of the working state of the present invention.
Fig. 2 is a schematic structural view of the utility model when the mandril is retracted.
Fig. 3 is a left side view of fig. 1.
Fig. 4 is a left side view of fig. 2.
In the figure: 1. the car bottom plate locking device comprises a top rod, 2 support assemblies, 3 rotating connecting plates, 4.UKT automatic reset switch fixing plates, 5. locking plates, 6. rotating locking plates, 7. switch striking plates, 8. guide rails, 9. guide rail pressing plates, 10.UKT automatic reset switches and 11. car bottom plates.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
In fig. 1 to 4, an elevator overhaul safety device comprises a guide rail 8 and a mandril 1 movably connected with the guide rail, and is characterized in that: the right side symmetry movable mounting at the upper and lower both ends of ejector pin 1 has rotating connection plate 3, the other end of rotating connection plate 3 and the left end swing joint of backup pad 2, backup pad 2 passes through guide rail clamp plate 9 fixed mounting on guide rail 8, backup pad 2 is close to the one end movable mounting of ejector pin 1 has rotatory locking plate 6, go back fixed mounting on ejector pin 1 and have locking plate 5 with rotatory locking plate 6 and backup pad 2 matched with, it has fixed plate 4 to go back fixed mounting on guide rail 8, fixed plate 4 is close to the one end fixed mounting of ejector pin 1 has UKT automatic re-setting switch 10, fixed mounting has the switch tie plate 7 with UKT automatic re-setting switch 10 matched with on the ejector pin 1, UKT automatic re-setting switch 10 establishes ties with the electrical control safety circuit of elevator.
The utility model adopts the technical scheme that a support plate 2 is fixed on a guide rail 8 by a guide rail pressing plate 9, a push rod 1 is connected with the support plate 2 by a rotary connecting plate 3, and a switch beating plate 7 and the push rod 1 are driven to be in a circular arc motion track by the rotation of the rotary connecting plate 3, so that an UKT automatic reset switch 10 is triggered, the power supply of an elevator is switched on at the moment, and the elevator works normally; and then the locking plate 5 is clamped between the rotating locking plate 6 and the supporting plate 2 by rotating the rotating locking plate 6, so that the retraction action of the ejector rod is realized. When the maintainer need get into the pit, only need to rotate rotatory locking plate 6, utilize the gravity of ejector pin 1 to realize that the automation of ejector pin falls to the ground, switch beat the board 7 and leave UKT automatic re-setting switch 10, the elevator outage this moment guarantees maintainer's safety.
