Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a leveling locking device for an elevator or a lifting machine. Background Art

[0002] Floor locking for elevators or lifts is one of the core technologies for safe elevator operation. Its core goal is to ensure that the car is precisely aligned with the landing door when it stops at the floor, and to prevent accidental movement through the locking mechanism, ensuring the safe entry and exit of passengers.

[0003] The leveling locking structure in the existing technology usually requires real-time monitoring of the car position through an encoder, photoelectric sensor or magnetic induction device, and comparing it with the preset floor position data, so as to control the electromagnetic brake to automatically engage after leveling, fix the traction machine shaft, and prevent the car from sliding. However, when part of the structure of the above-mentioned locking device fails, there is a lack of additional mechanical structure to support the elevator car. Therefore, a leveling locking device for an elevator or lifting machine is proposed to solve the above-mentioned problem. Summary of the Invention

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] An elevator or lift leveling locking device comprises an elevator, wherein both sides of the elevator are provided with locking mechanisms;

[0006] The elevator includes a car, a hanging plate guide rail is fixedly installed on the upper end of the front of the car, and slide grooves are provided on both sides of the front of the hanging plate guide rail. Each of the slide grooves is consistent with the hanging plate guide rail in the length direction, and a buffer pad is bonded and fixed on both sides of the inner wall of each of the slide grooves;

[0007] Among them, locking rods are also slidably connected on both sides of the inner wall of the hanging plate guide rail, and each locking rod is fixedly connected to a clamping block at both ends of one side close to the middle of the hanging plate guide rail, and pulleys are rotatably connected on the surface of the locking rod and located above and below each clamping block.

[0008] As a further solution of the present invention: the front end of the clamping block extends to the inner side of the slide groove, and each of the pulleys is slidably connected along the inner side of the slide groove, and the side edges of the pulleys also abut against the surface of the buffer pad.

[0009] As a further solution of the present invention: door hanging plates are slidably connected to both sides of the outer wall of the hanging plate guide rail, and the upper end of the back side of each door hanging plate is symmetrically connected to a clamping wheel for rotation, and the bottom surface of each clamping wheel is slidably connected to the upper surface of the hanging plate guide rail.

[0010] As a further solution of the present invention: a push block is fixedly connected to the middle of the back side of each door hanging plate, the rear end of the push block extends into the inside of the slide groove, and both sides of each push block are respectively against the clamping block.

[0011] As a further solution of the present invention: a car door guide rail is fixedly installed at the lower end of the front side of the car, and a car door body is slidably connected to both sides of the top surface of the car door guide rail, and the top surfaces of the two car door bodies are respectively fixedly installed with door hanging plates.

[0012] As a further solution of the present invention: the locking mechanism includes an elevator shaft mounting plate, and there are two elevator shaft mounting plates in total. The surface of each elevator shaft mounting plate is penetrated and connected with fastening bolts on all four sides. A locking sleeve is fixedly installed in the middle of the surface of the elevator shaft mounting plate, and a dust blocking plate is fixedly connected to the top of the locking sleeve. The bottom surface of the locking sleeve is provided with several dust discharge ports.

[0013] As a further solution of the present invention: each of the elevator shaft mounting plates is respectively arranged on both sides of the car, and the inner wall of the locking sleeve is plugged into the locking rod.

[0014] Beneficial effects of the present invention:

[0015] (1) The present invention provides an additional mechanical locking structure in the door hanging plate area above the elevator car door. When the car door is opened to both sides, it can drive the locking rod to insert into the locking sleeves installed on both sides in the elevator shaft, thereby providing auxiliary support for the front end of the elevator to prevent the car from shaking due to the forward shift of the center of gravity of the car when the people in the car walk out.

[0016] (2) The surface of the locking rod is connected to the pulley and moves along the slide groove. Rubber buffer pads are set on both sides of the slide groove to prevent the pulley from bumping when it moves to the end of the slide groove, reducing the noise when the locking rod moves. In addition, an ash baffle is set above the locking sleeve connected to the locking rod to prevent the dust in the elevator shaft from entering the inside of the locking sleeve, and an ash discharge port is opened on the bottom surface of the locking sleeve. When the locking rod is inserted into the locking sleeve, the locking rod can push any debris that may exist in the locking sleeve to the outside of the ash discharge port, thereby avoiding connection jamming, which causes the elevator door to fail to open and close normally.

Figure 4 、 Figure 5 As shown, the buffer pad 109 prevents the pulley 112 from directly hitting the inner wall of the chute 108, thereby reducing noise;

[0026] The front end of the clamping block 111 extends to the inner side of the slide groove 108, and each pulley 112 is slidably connected along the inner side of the slide groove 108, and the side of the pulley 112 is also against the surface of the buffer pad 109. Figure 4 、 Figure 5 As shown, there is a gap between the clamping block 111 and the pulley 112, thereby preventing the friction between the clamping block 111 and the pulley 112 from hindering the normal opening and closing of the elevator door.

[0027] The outer walls of the hanging plate guide rail 107 are slidably connected to the door hanging plates 104 on both sides, and the upper end of the back of each door hanging plate 104 is symmetrically connected to the clamping wheel 105, and the bottom surface of each clamping wheel 105 is slidably connected to the upper surface of the hanging plate guide rail 107. The middle part of the back of each door hanging plate 104 is fixedly connected to a push block 106, the rear end of the push block 106 extends to the inside of the slide groove 108, and the two sides of each push block 106 are respectively against the clamping block 111. Figure 4-Figure 5 As shown, the push block 106 is inserted between two adjacent clamping blocks 111, and the distance between adjacent clamping blocks 111 is consistent with the width of the push block 106;
