Abstract
A mechanical interlocking device for a feeding door of a lift cage relates to an aid for a lift and is provided with a toothed plate, a beak and a touch block. The toothed plate is mounted on a cage door; the beak is mounted on a cage door frame; the touch block is mounted on a ground fence; and a gap is reserved between the upper portion of the beak and the touch block. In the whole operating cycle, the beak has no action if the feeding door of the cage is not opened, when the cage runs to a ground station and the feeding door is opened, the upper portion of the beak is abutted rightwards to the touch block on the fence under the action of the a spring, and acting force is extremely small so that no sliding fiction is generated. When the cage leaves the position of the bottommost layer, the cage feeding door is opened upwards, the upper portion of the beak is opened rightwards under the action of the spring without being blocked by the touch block on the fence, the lower portion of the beak is abutted to teeth of the toothed plate, and then the cage door cannot be opened upwards any more so that automatic opening of the cage door is prevented. In the whole interlocking process, the action of the beak is slight without friction or damage, the reliability of the interlocking device is improved, the service life of the interlocking device is prolonged, and the safety performance of the interlocking device in use is improved.
Description
Technical field
The utility model relates to a kind of auxiliary device of elevator, especially relates to a kind of elevator craning cage feeding gate mechanical interlocks.
Background technology
Cage feeding gate mechanical interlocks is the visual plant in the elevator, the existing mechanical interlock system mainly by be installed in the tooth plate on the cage door, the beak that is installed on the cage doorframe is formed, collision block on being installed in the ground fence is worked, and plays the effect of mechanical interlock.Its principle of work is: when cage stopped at the bottom, the top of beak contacted with collision block on the fence, and the bottom of beak breaks away from tooth plate, and the cage feeding gate can arbitrarily be opened or close this moment.When building hoist was worked, personnel closed the cage feeding gate after entering cage or installing material, upwards operation, and beak top breaks away from collision block, withstands tooth on the tooth plate because of action of the spring beak bottom, and the cage feeding gate just can not upwards spur unlatching.But break away from collision block at every turn friction and slip are all arranged.In the whole working cycle, when particularly cage enters the bottom from the top down, beak top promotes beak top left with to be installed in collision block on the fence gate be behind the cliding friction and overcome spring force, application force and sliding stroke is all bigger longitudinally, and impact bigger to collision block when moving contact because of cage, and this mechanical interlock mechanism to be each working cycle of cage all must move once, act frequently, so often cause spring failure and cause interlock mechanism to be lost efficacy.
Summary of the invention
The purpose of this utility model is to provide the improved elevator craning cage feeding gate mechanical interlocks that a kind of reliability is better, service life is long.
The utility model is provided with tooth plate, beak and collision block; Tooth plate is installed on the cage door, and beak is installed on the cage doorframe, and collision block is installed on the fence of ground, the top of beak and be installed between the collision block of described ground fence and leave the gap.
The width in described gap can be 1.5～2.5mm.
Compare with existing elevator craning cage feeding gate mechanical interlocks, the utlity model has following outstanding advantage:
Owing to leave the gap of 1.5～2.5mm between the last collision block of the utility model with the top of beak and described ground fence, therefore in the whole working cycle, if the feeding gate of not opening cage then beak does not have any employing, when cage runs to the ground stop and opens feeding gate, leave the gap between the collision block because of the top of beak and ground fence, beak top also has only the action about 1.5～2.5mm, be that cage is when static, beak top leans against on the collision block of fence to the right because of action of the spring, application force is very little, also fricton-tight friction.But if left the position of the bottom at cage, when the cage feeding gate upwardly opens, open to the right because of action of the spring on beak top, because of the collision block on the no fence blocks, the bottom just withstands on the tooth of tooth plate, the cage door just can not upwards have been opened again, has also played the effect that prevents cage door self-opening.And in the whole interlocking process, the action of beak is all very slight, and not friction and damage basically improved this greatly and overlapped the reliability and the service life of interlock mechanism, improved the safety performance that equipment uses.
Description of drawings
Fig. 1 is that the structure of the utility model embodiment is formed scheme drawing.
Fig. 2 is one of the running condition of a utility model embodiment scheme drawing.
Fig. 3 is two scheme drawings of the running condition of the utility model embodiment.
The specific embodiment
Referring to Fig. 1～3, the utility model embodiment is provided with tooth plate 1, beak 2 and collision block 3.Tooth plate 1 is installed on the cage door M, and beak 2 is installed on the cage doorframe P, and collision block 3 is installed on the fence Q of ground, leaves the gap that width L is 1.5～2.5mm between the last collision block of the top of beak 2 and described ground fence Q.
Principle of work of the present utility model is: when cage stops at the bottom, if cage feeding gate (sliding door) is closed, the bottom of beak contacts with the upper plane of tooth plate, this moment is when upwards moving, and there is not mutual action between the collision block, make collision block on the top of beak and the fence also maintain the gap of 1.5～2.5mm, do not have direct contact; If when being parked in the bottom and being pulled upwardly the cage feeding gate, (stroke just stops to have moved after having only 1.5～2.5mm) because of action of the spring beak top touches collision block on the fence, the bottom of beak also do not enter into the tooth plate bottom tooth on, do not mesh with tooth plate as yet, (referring to Fig. 2) can be arbitrarily opened or close in the cage charging.When building hoist was worked, personnel closed the cage feeding gate after entering cage or installing material, upwards operation, the gap that also maintains 1.5～2.5mm because of the top and the collision block on the fence of beak, thus during operation and collision block do not have interaction force, beak is attonity also.In the whole working cycle, if the feeding gate of not opening cage then beak do not have any employing, also have only the action of 1.5～2.5mm when opening feeding gate, be that cage is when static, beak top leans against to the right on the collision block of fence because of action of the spring, and application force is very little, also fricton-tight friction.But if left the position of the bottom at cage, when the cage feeding gate upwardly opens, open to the right because of action of the spring on beak top, because of the collision block on the no fence blocks, the bottom just withstands on the tooth of tooth plate, the cage door just can not upwards have been opened again, has also played the effect that prevents cage door self-opening.And in the whole interlocking process, the action of beak is all very slight, and not friction and damage basically improved this greatly and overlapped the reliability and the service life of interlock mechanism.
