Abstract
The utility model discloses a lifting cage door lock of a construction lifter. The lifting cage door lock of the construction lifter comprises a seat board, an oblique thorn-shaped block, a tooth block and a rotation stopper block, wherein the tooth block is located on one side of the seat board, the rotation stopper block is located on the other side of the seat board, and a rotation shaft is arranged on the seat board. The oblique thorn-shaped block is provided with a rotation hole matched with the rotation shaft, and can be divided into two portions, one portion is located on the side of the tooth block, the other portion is located on the side of the rotation stopper block, and the position of the rotation hole enables the portion located on the side of the tooth block to be lighter than the other portion located on the side of the rotation stopper block. One side surface of the tooth block faces towards the oblique thorn and is provided with tooth notches, and the oblique thorn-shaped block is provided with a thorn-shaped head. The lifting cage door lock of the construction lifter has the advantages of being simple in structure, reliable in self-locking, and long in service life.
Description
Technical field
The utility model belongs to the building machinery technical field, relates to construction elevator, relates in particular to construction elevator cage door lock.
Background technology
Construction elevator is claimed construction elevator again, is a kind of employing gear, tooth bar engagement system or rope hoisting mode, makes cage make vertical or banking motion; In order to carry the building machinery of constructor, instrument, equipment and material; Other hoisting mechanism of its friendship is stable, safe and reliable, need not establish machine room or hoistway in addition, and has advantages such as easy accessibility, carrying flexibility are strong; Be widely used; Especially in alleviating constructor's labour intensity, speed up the work, increasing work efficiency, play tangible effect.
The cage door lock is the significant components of hoist safety, when cage when operation door can not open, otherwise be prone to accidents; When cage is only got back to ground base station; The cage door could be opened, and all adopts the spring pressure return with front door lock, when utilization and operation certain hour rear spring lost efficacy; Door lock does not have effect, directly jeopardizes constructor's personal safety.
The utility model content
For this reason, the utility model technical problem to be solved provides that a kind of simple in structure, self-locking is reliable, the construction elevator cage door lock of long service life, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of construction elevator cage door lock; It is characterized in that: comprise seat board, stab, lay respectively at the tooth piece and the spline piece of seat board both sides diagonally; Have rotating shaft on the said seat board, the diagonal stabbing of institute family has the commentaries on classics hole in the rotating shaft of being engaged in, and position, said commentaries on classics hole makes that being positioned at tooth piece side sections is lighter than and is positioned at spline piece side sections; Said tooth piece has the tooth mouth towards the side of diagonal stabbing, and said diagonal stabbing has the thorn point that snaps in the tooth mouth.
In the practical implementation of the utility model was implemented, said tooth mouth was the right-angled triangle tooth that right-angle side is positioned at the below.
In addition, said diagonal stabbing is provided with runner at tail end.
Adopt technique scheme, that this construction elevator cage door lock of the utility model has is simple in structure, self-locking reliable, the advantage of long service life.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated:
Fig. 1 is the structural representation of the utility model;
Among the figure:
The 100-seat board, the 101-rotating shaft, the 200-diagonal stabbing, 201-stings point, the 202-runner, 203-changes the hole, 300-tooth piece, 301-tooth mouth, 400-spline piece.
The specific embodiment
As shown in Figure 1, the construction elevator cage door lock of the utility model comprises seat board 100, diagonal stabbing 200, tooth piece 300 and spline piece 400.
Wherein, Tooth piece 300 and spline piece 400 lay respectively at the both sides of seat board 100; Have rotating shaft 101 on the seat board 100, have the commentaries on classics hole 203 that cooperates with rotating shaft 101 on 200, change 201 positions, hole and make diagonal stabbing 200 be positioned at tooth piece 300 side sections to be lighter than and to be positioned at spline piece 400 side sections and stab diagonally.Tooth piece 300 has 2 tooth mouths 301 towards the side of diagonal stabbing 200, and this tooth mouth 301 is the right-angled triangle tooth, and its right-angle side is positioned at the below.Have the thorn point 201 that snaps in the tooth mouth 301 and stab 200 front ends diagonally, runner 202 also is installed at tail end.
More than be exactly the construction elevator cage door lock of the utility model, its working method is following:
1, the descending ground base station of getting back to of cage, runner 202 is run into the swash plate piece that is contained on the outer cage, and runner 202 pressurizeds upwards drive ratchet 200 and rotate the tooth piece 300 that ratchet 201 is broken away from the cage door around rotating shaft 101, and the cage door can upwards draw back,
2, the cage door of leaving behind, the operation cage rises, the swash plate piece that runner 202 breaks away from the outer cage; Because ratchet 200 tops are heavy, under the effect of gravity, 101 rotating around the shaft, ratchet 200 snaps in the tooth mouth 301 of tooth piece 300; If firmly upwards draw the cage door; Because ratchet 200 can not be rotated by spline piece 400 restriction, so the cage door can not open, and plays the locking effect.
Through above-mentioned detailed description, can find out that this construction elevator cage door lock of the utility model has is simple in structure, self-locking reliable, the advantage of long service life.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
