2. The handle is arranged on the lock rod, so that maintenance personnel can hold the handle to pull the lock rod to insert the lock rod into the lock hole or withdraw the lock rod from the lock hole, and the operation is simple and convenient.
3. The side plates are provided with rectangular holes, the rectangular holes can limit the moving space of the handle so as to limit the moving distance of the lock rod, and the metal sheet is prevented from impacting the metal sensor to damage the metal sensor.
4. Be equipped with the knob of second screw rod and control second screw rod action in the curb plate, when the locking lever inserted the lockhole, after the handle swung the bottom in U-shaped hole, twisted the second screw rod through rotatory knob and made first screw rod stretch out, thereby prevented the locking lever roll-off from the lockhole in the bottom in U-shaped hole to the handle restriction, increased the safety guarantee when maintenance personal maintained.
Drawings
The following detailed description of embodiments of the invention is provided in conjunction with the appended drawings, in which:
fig. 1 is a schematic structural view of an elevator locking device of the invention;
fig. 2 is a schematic view of the elevator locking device of the present invention with the locking bar inserted into the locking hole;
FIG. 3 is a cross-sectional view of a side panel of the present invention;
fig. 4 is an enlarged view of the structure of part a of fig. 3 in the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1 to 4, the elevator locking device comprises a locking plate 1 and a bottom plate 2, wherein a locking rod 3 for locking an elevator car on the locking plate 1 and a metal sensor 4 for sensing metal and breaking an elevator safety circuit are arranged on the bottom plate 2, a metal sheet 5 for sensing the metal sensor 4 is arranged at one end of the locking rod 3, which is far away from the locking plate 1, and a locking hole 11 for inserting the locking rod 3 is arranged on the locking plate 1.
When maintenance personnel need to enter an elevator shaft, the lock rod 3 is inserted into the lock hole 11 of the lock plate 1, the car can be locked on the lock plate 1, the car can be prevented from falling off, and therefore the maintenance personnel can be injured, at the moment, the metal sheet 5 fixed to the other end of the lock rod 3 can be close to the metal sensor 4, the metal sensor 4 senses the metal 5 and then breaks a safety circuit of the elevator, casualties of personnel caused by the fact that the elevator runs due to the fact that other people touch a switch of the elevator by mistake in the maintenance process are prevented, after the elevator is maintained, the lock rod 3 is withdrawn from the lock hole 11, at the moment, the metal sheet 5 is far away from the metal sensor 4, the metal sensor 4 cannot sense the metal and then closes the safety circuit of the elevator again, and therefore the elevator can run normally.
The handle 31 for pulling the lock rod 3 by holding by hand is arranged on the lock rod 3, so that the maintenance personnel can insert the lock rod 3 into the lock hole 11 of the lock plate by only holding the handle 31 to pull the lock rod 3, and the operation is simple and convenient.
The bottom plate 2 is provided with a side plate 6, the side plate 6 is provided with a rectangular hole 61 for providing a space for the handle 31 to move in the left-right direction, and the left end and the right end of the rectangular hole 61 are provided with U-shaped holes 62 for providing a space for the handle 31 to swing in the up-down direction.
The bottom plate 2 is provided with a lock rod seat 7 for installing the lock rod 3, and the lock rod seat 7 is provided with a through hole for the lock rod 3 to pass through and guiding the lock rod 3.
The lock lever 3 is a circular lever that can rotate around its central axis.
When a maintenance person pulls the handle 31 to enable the handle 31 to move in the rectangular hole 61, the rectangular hole 61 can limit the moving space of the handle 31 in the left-right direction and further limit the moving distance of the lock rod 3, the metal sheet 5 is prevented from colliding on the metal sensor 4 due to the fact that the distance of pulling the handle 31 is too large to damage the metal sensor 4, the lock rod 3 can rotate around the central shaft of the lock rod 3, the handle 31 can swing to the lowest end of the U-shaped hole 62 to be fixed, and the lock rod 3 is prevented from moving left and right.
