Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance, and specifically relates to an anti-falling rod dedicated to elevator maintenance. Background Technique

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. When maintaining an elevator, an anti-falling rod is needed to ensure the safety of maintenance personnel.

[0003] At present, when using the anti-falling rod for elevator maintenance, the anti-falling rod needs to be placed at the elevator door. The anti-falling rod supports at the elevator door, and the safety rope is hung above the anti-falling rod to prevent the worker from falling during maintenance. Since most anti-falling rods are simply placed at the elevator door and are stabilized by the extended rod body blocking outside the elevator door, the anti-falling rod is not firmly stabilized, and it will shift during actual use, reducing the safety of elevator maintenance. Secondly, when the safety rope is hung above the anti-falling rod, the safety rope will rub against the edge of the elevator opening, easily causing damage to the safety rope and reducing the safety of elevator maintenance.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, when a maintenance worker enters the interior of the elevator shaft, the rope will generate a pulling force, which in turn drives the stable frame to move. The movement of the stable frame drives the trapezoidal block to move. The movement of the trapezoidal block is limited by the fixed rod and the limit plate. At the same time, the inner wall of the limit chute moves along the outer wall of the limit plate, and then the limit plate squeezes the return spring. When the trapezoidal block is driven by the pulling force to move, the inclined surface of the trapezoidal block squeezes the inner wall of the inclined chute, and the inclined chute being squeezed drives the movable plate to move. The movement of the movable plate drives the push plate and the rubber plate to move towards the inner side of the elevator door. By squeezing the inner side of the elevator door with the rubber plate, the stable fixing frame is thus stabilized. When the movable plate moves, the stable chute moves along the outer wall of the movable plate, and the sliding chute moves along the outer wall of the limit block, thereby limiting and stabilizing the movable plate. Through the pulling force generated by the maintenance worker entering the interior of the elevator shaft on the rope, the rubber plate is driven to squeeze the inner side of the elevator door, increasing the stability of the device during use, avoiding the phenomenon of the device shifting, and increasing the safety of use.

[0013] In the present utility model, the fixing frame is placed at the elevator door opening. At the same time, the blocking plate is blocked by the elevator door opening, and the rubber plate is located inside the elevator door opening. The safety rope is hung above the hanging rod, and the rope is located between the protective sleeves. First, rotate the threaded rod, and through the threaded groove, drive a set of extension plates to move towards the direction of the other set of extension plates, thereby driving the moving ring to move along the outer wall of the hanging rod, and then driving the protective sleeve to move. The movement of the protective sleeve wraps the rope. When the maintenance worker enters the interior of the elevator shaft, the outer wall of the protective sleeve contacts the edge of the elevator door opening. Through the protection of the protective sleeve for the safety rope, the phenomenon of the safety rope being damaged when contacting the edge of the elevator door opening is avoided.

The movement of the movable plate 401 drives the push plate 405 and the rubber plate 406 to move towards the inner side of the elevator door, and the inner side of the elevator door is pressed by the rubber plate 406.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown in the figure, the safety rope stabilizing mechanism 5 includes a stabilizing frame 501, a hanging rod 502, a moving ring 503, an extension plate 504, a threaded groove 505, a threaded rod 506, and a protective sleeve 507. One side of the stabilizing frame 501 is fixedly connected to one side of the trapezoidal block 301. One side of the stabilizing frame 501 is fixedly connected to one end of the hanging rod 502. The outer wall of the hanging rod 502 is movably connected to the inner wall of the moving ring 503. The bottom end of the moving ring 503 is fixedly connected to the top end of the extension plate 504. A threaded groove 505 is provided inside one side of the extension plate 504.

At the same time, the rope is located between the protective sleeves 507. First, rotate the threaded rod 506 to drive a group of extension plates 504 to move towards the other group of extension plates 504 through the threaded groove 505, thereby driving the moving ring 503 to move along the outer wall of the hanging rod 502, and then driving the protective sleeve 507 to move. The movement of the protective sleeve 507 wraps the rope. When the maintenance personnel enter the elevator shaft, the outer wall of the protective sleeve 507 contacts the edge of the elevator door opening.

[0031] The usage method and advantages of the present invention: When the anti-falling rod dedicated to elevator maintenance works, the working process is as follows:

[0032] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, place the fixing frame 101 at the elevator door. At the same time, the blocking plate 102 is blocked by the elevator door, and the rubber plate 406 is located inside the elevator door. Hang the safety rope above the hanging rod 502, and the rope is located between the protective sleeves 507. First, rotate the threaded rod 506 to drive a set of extension plates 504 to move towards the other set of extension plates 504 through the threaded groove 505, thereby driving the moving ring 503 to move along the outer wall of the hanging rod 502, and then driving the protective sleeve 507 to move. The movement of the protective sleeve 507 wraps the rope. When the maintenance personnel enter the elevator shaft, the outer wall of the protective sleeve 507 contacts the edge of the elevator door. At the same time, when the maintenance personnel enter the elevator shaft, the rope will generate a pulling force, which will then pull the stabilizing frame 501 to move. The movement of the stabilizing frame 501 drives the trapezoidal block 301 to move. The movement of the trapezoidal block 301 is limited by the fixing rod 306 and the limiting plate 305. At the same time, the inner wall of the limiting chute 302 moves along the outer wall of the limiting plate 305, and then the limiting plate 305 squeezes the return spring 304. When the trapezoidal block 301 is driven by the pulling force to move, the inclined surface of the trapezoidal block 301 squeezes the inner wall of the inclined groove 402. The inclined groove 402 being squeezed drives the movable plate 401 to move. The movement of the movable plate 401 drives the pushing plate 405 and the rubber plate 406 to move towards the inside of the elevator door. The rubber plate 406 squeezes the inside of the elevator door, thereby stabilizing the fixing frame 101. When the movable plate 401 moves, the stabilizing groove 403 moves along the outer wall of the movable plate 202, and the sliding groove 404 moves along the outer wall of the limiting block 203, thereby limiting and stabilizing the movable plate 401.
