Abstract

The utility model discloses a manual unlocking device of a hoistway door, comprising a second rotating shaft internally provided with a keyhole, a hook and a first rotating shaft, wherein the hook can rotate around the first rotating shaft; the hook part of the hook is hook-jointed and fastened with the hook on the top of the hoistway door; furthermore, a spring which can provide a resilience is arranged above the hook and between the first rotating shaft and the hook part; the external circumferential edge of the second rotating shaft is fixedly connected with a rotating wheel; a rope in a tensioning state is connected between the rotating wheel and the hook; and the connecting position of the rope and the hook is arranged at one side in the hook, opposite to the hook part. The manual unlocking device has the advantages of saving material, and being convenient to assemble.

Description

The manual unlocking apparatus of hoistway door
Technical field
The relevant a kind of manual unlocking apparatus that is used for the breakdown hoistway door of the utility model.
Background technology
Existing vertical lift all is equipped with manual unlocking apparatus in the elevator hall of each layer, so that when being in an emergency or keep in repair, can utilize manual unlocking apparatus opening elevator Room door, as shown in Figure 1, in including, establishes existing manual unlocking apparatus second rotating shaft 2 of the key hole 1 that mates with key, the eccentric block 3 of captiveing joint with second rotating shaft 2, ejector pin 6 and link up with 8, hook 8 can be around rotating with first rotating shaft 9 of elevator support bonded assembly, the hook portion 12 of hook 8 is connected with the fastener 7 at hoistway door top, ejector pin 6 is positioned at hook 8 belows, and between the hook portion 12 and first rotating shaft 9, the upper end of ejector pin 6 is replaced with hook 8, lower end and eccentric block 3 offset, above hook 8, be provided with and push away the spring 11 of low hook 8 toward next pressure, on ejector pin 6, be arranged with simultaneously and be used to push against the spring 4 that eccentric block 3 sets back and replace piece 5, concrete operating process is: the maintainer inserts triangular key in the key hole 1, screw key, drive rotating shaft 2 rotations, and drive eccentric block 3 rotations, thereby promoting push rod 6 moves up, pushing tow hook 8 rotates around first rotating shaft 9, make the hook portion 12 of hook 8 and fastener 7 disengagings of hoistway door, throw off the locking of 8 pairs of fasteners 7 of hook, thus can manually opened elevator hall (not shown).When not needing to withdraw from key when manually opened, make push rod 6 and link up with 8 by means of the restoring force of spring 11,4 to return to original position.
This manual unlocking apparatus has following deficiency in use:
Because key hole must be located at the position of the convenient plug of maintenance person, and hook must be located at the top of lift car, therefore make that the distance L 1 between eccentric block and the hook is long, thereby cause ejector pin long, so in order to reach the stiffness of ejector pin, must increase the cost of material, and have the inconvenient problem of installing.
The utility model content
The purpose of this utility model is to provide a kind of features simple structure, uses more reliable, safe manual unlocking apparatus.
In comprising, the manual unlocking apparatus of hoistway door in the utility model is provided with second rotating shaft of key hole, hook, first rotating shaft, described hook can rotate around described first rotating shaft, the hook portion of described hook hooks together with the fastener at described hoistway door top and is connected locking, and between described first rotating shaft and described hook portion, be provided with the spring that restoring force can be provided above the described hook, the outer peripheral edges of described second rotating shaft are fixedly connected with runner, be connected with the rope that is tension between described runner and described hook, described rope is arranged in a side opposite with described hook and hook portion with the connection location of described hook.
Described hook is arranged in described and the opposite side of hook hook portion and is provided with and is used for the hole that is connected and fixed with described rope.
Described second rotating shaft and described runner are connected and fixed by screw or other securing devices.
The manual unlocking apparatus of hoistway door in the utility model is owing to use rope, thereby can change at any time according to the position that the key hole of bottom and top are linked up with, and reduced difficulty of processing and material cost, and is easy for installation.
Description of drawings
Fig. 1 is the structural representation of existing manual unlocking apparatus;
Fig. 2 is the structural representation of manual unlocking apparatus in the utility model;
Fig. 3 is the enlarged diagram of A part among Fig. 2.
The specific embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 2 and 3, be provided with second rotating shaft 2 of key hole 1 in the manual unlocking apparatus of hoistway door comprises in the utility model, with the runner 14 that second rotating shaft 2 is captiveed joint, rope 15 and link up with 8.Wherein be connected and fixed by screw or other securing devices between second rotating shaft 2 and the runner 14.Hook 8 structure, shape are all identical with hook in the existing elevator in the utility model, be provided with hook portion 12, and can rotate around first rotating shaft 9, the hook portion 12 of hook 8 is connected with the fastener 7 at hoistway door top, fastener 7 is captiveed joint with hoistway door, and above hook 8, between first rotating shaft 9 and hook portion 12, be provided with spring 11, and be positioned at an end opposite with hook portion 12 and be provided with the hole 10 that is used to be connected and fixed rope 15 linking up with 8.The two ends of rope 15 are connected to hook 8 and runner 14, and are tension, and wherein rope 15 and the connection of linking up with 8 are positioned at a side opposite with hook portion 12, promptly are connected and fixed with hole 10.When the manually opened hoistway door of needs, key is inserted in the key hole 1, and screw key, so can drive second rotating shaft 2 and rotate, rotate, rope be rotated take turns 14 windings thereby drive runner 14, pulling hook 8 makes the hook portion 12 of hook 8 and fastener 7 break away from the opening elevator Room.And when not needing the opening elevator door,, make hook around first rotating shaft, 9 rotations by means of the strength of spring 11, and drive the runner counter-rotation by rope 15, return to locking position.
