Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to 5, it is the utility model provides an elevator overhauls locking device's structure schematic diagram. The elevator maintenance locking device comprises a support 10, an inserting plate 20 positioned on one side of the support 10, a safety switch 30 arranged on the support 10, an inserting rod 40 movably arranged on the support 10 and a limiting rod 50 arranged on the inserting rod 40. It is conceivable that the elevator service locking device further comprises other functional modules, such as connecting members, elevator car roofs, and elevator guide rails, etc., which are well known to those skilled in the art and will not be described herein again.

The bracket 10 is fixed to the edge of the elevator car and is used to arrange the safety switch 30 and the plunger 40, so that the bracket is provided with various functional structures such as screws, bolts, etc. to accomplish the installation with the elevator car, which can be arranged according to actual needs, and will not be described in detail herein.

Two through holes 11 which are coaxially arranged are respectively arranged at two sides of the bracket 10, and the central axes of the through holes 11 are vertical to the plane of the inserting plate 20. The through hole 11 is used for movably inserting the insertion rod 40 and determining the moving direction of the insertion rod 40, so that the insertion rod 40 can only move along the central axis of the through hole 11, and the insertion rod 40 moves towards the direction close to or far away from the insertion plate 20, so as to insert or extract the insertion rod 40 into or out of the insertion plate 20.

The bracket 10 is provided with a sliding groove 12. The sliding groove 12 is used for sliding the limiting rod 50, so that the inserted rod 40 is driven to move by moving the limiting rod 50. The sliding chute 12 is of an I-shaped structure and includes a sliding section 122 and two fixing sections 122 disposed at two ends of the sliding section 122. The extending direction of the sliding section 122 is parallel to the moving direction of the inserting rod 40, the two fixing sections 122 are perpendicular to the sliding section 122, and the two fixing sections 122 are respectively used for fixing the position of the limiting rod 50 when the inserting rod 40 extends out or retracts, so that the inserting rod 40 is fixed, and the phenomenon that the inserting rod moves to touch the safety switch 30 by mistake to affect the safety is prevented. The concrete description of the slide groove 12 will be described below in conjunction with the stopper rod 50.

The inserting plate 20 is provided with a plurality of mounting holes 21 and a plurality of inserting holes 22, the inserting plate 20 is fixed on an elevator guide rail by arranging fixing pieces in the mounting holes 21, and the inserting holes 22 are used for inserting the inserting holes 40, so that the inserting rods 40 are further fixed.

The safety switch 30 is a microswitch and is connected with a safety loop of the elevator, the safety loop is disconnected when the safety switch 30 is triggered, and the safety loop is disconnected when the safety switch 30 is not triggered. The safety loop of the elevator is that each safety component of the elevator is provided with a safety switch, all the safety switches are connected in series to control a safety relay. Only all safety switches all switch on, safety relay just can the actuation, and the elevator just can have the electricity operation, as long as there is a safety switch disconnection, whole safety circuit will break off for the elevator outage can't be moved, and the safety circuit of elevator should be prior art, no longer gives details here. The safety switch 30 is located in the moving direction of the inserting rod 40, so that when the inserting rod 40 moves towards the inserting plate 20, the safety switch 30 can be triggered to disconnect a safety loop, thereby ensuring that the elevator cannot run when the elevator is powered off.

The insertion rod 40 is movably inserted into the two through holes 11, that is, the insertion rod 40 can move or rotate along the through holes 11. The limiting rod 50 is inserted into the sliding groove 12 and can slide in the sliding groove 12, one end of the limiting rod 50 is connected with the outer side wall of the inserted link 40, and the movement of the inserted link 40 can be controlled by moving the limiting rod 50 in the sliding groove 12. Because the two fixing sections 122 are perpendicular to the sliding section 122 and the inserted link 40 can rotate, the limiting rod 50 can be pulled off, so that the limiting rod 50 enters the fixing sections 122 and is clamped in the fixing sections 122, the limiting rod 50 is fixed when the inserted link 40 extends or retracts, and the inserted link 40 is prevented from mistakenly touching the safety switch 30 during normal operation of the elevator or being separated from the safety switch 30 during maintenance to influence safety. Meanwhile, the sliding groove 12 is I-shaped, so that the limiting rod 50 can be pulled upwards or downwards to enter the fixing section 122 when being fixed, thereby improving the convenience of operation.

When the elevator is in normal operation, the limiting rod 50 is located in the fixing section 122 far away from the inserting plate 20, so that the inserting rod 40 retracts to not touch the safety switch 30, and a safety circuit is normally connected. When the maintenance is needed, a worker enters the top of the elevator car, breaks the limiting rod 50 to move along the sliding section 122 and is clamped into the fixing section 122 close to the inserting plate 20. The inserting rod 40 is moved towards the inserting plate 20 and inserted into the inserting hole 22, and simultaneously touches the safety switch 30, so that a safety loop is disconnected, and the elevator cannot run, and is convenient to overhaul.

Compared with the prior art, the utility model provides an elevator overhauls locking device passes through spout 12 with gag lever post 40 controls inserted bar 40 stretches out or the withdrawal to disconnection or switch-on safety circuit. The sliding chute 12 is of an I-shaped structure and includes a sliding section 122 and two fixing sections 122 disposed at two ends of the sliding section 122. The two fixing sections 122 can fix the limiting rod 50 when the inserted link 40 extends or retracts, so that the inserted link 40 is prevented from mistakenly touching the safety switch 30 during normal operation of the elevator or being separated from the safety switch 30 during maintenance, and safety is guaranteed. The sliding groove 12 is I-shaped, so that the limiting rod 50 can be pulled upwards or downwards to enter the fixing section 122 when being fixed, thereby improving the convenience of operation. In addition, the elevator maintenance locking device is small in overall structure and small in occupied space, so that the requirement on installation space is low, and workers can conveniently maintain the elevator car.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
