Description

A kind of position-limit mechanism of door strap
Technical field
This utility model is related to elevator field of engineering technology, and in particular to a kind of position-limit mechanism of door strap.
Background technology
At present, it is typically mounted on door strap at the top of door of elevator in elevator industry, door strap is by mounted thereto The door change gear in face and position-limited wheel are slided in orbit.After layer door is impacted, door strap departs from running track, causes layer door to take off Fall, it is possible to cause personnel to fall the door area accident of hoistway.
GB7588-2003《Elevator is manufactured and installs safety standard》Specify in No. 1 amendment of national standard:It is fixed on door When guider on fan fails, horizontal sliding layer door and gate should have the device being maintained at door leaf on operating position.Keep Device can be regarded as the machinery for preventing door leaf from departing from its guiding, can be that an additional part can also be door leaf or hang A part for hang device.
Traditional mode is to clamp door guide rail by the change gear on door strap and upper pressing roller, to prevent door strap not light Easily depart from the track of door guide rail, but the method is also possible to door can be made due to change gear stress deformation when enormous impact force is run into Link plate de-orbits.Another way is to process upper and lower positive stop hook to be engaged with guide rail channel guide section on door strap, will be spacing The end of hook is inserted in channel guide section.Although this mode can be to avoid link plate from being impacted in running and depart from and lead Rail, but the structure is difficult dismounting door strap, and it is high to the processing request of door strap.It is also a kind of to prevent what door strap de-orbited Method, is to form a fastening plate by crossbeam bottom fold to encase upper pressing roller, and being hit, force direction pressing roller on is carried out It is spacing.Although can be to avoid link plate from being impacted in running and depart from guide rail, the guide rail difficulty of processing of the structure Greatly, production cost is high.
Utility model content
Not enough based on more than, the technical problems to be solved in the utility model is to provide a kind of door strap position-limit mechanism, its energy Enough ensure that door strap is moved on door guide rail bracket, and without departing from guide rail.
In order to solve above technical problem, this utility model employs technical scheme below:
A kind of position-limit mechanism of door strap, including door guide rail bracket, roller and position-limited wheel, the door guide rail bracket include main body with And the first guide rail on the body and the second guide rail are set, first guide rail and second guide rail direction are conversely, institute State roller to be each attached on door strap with the position-limited wheel, on the roller, be provided with the first guide groove, first guide groove and institute State the first guide rail to be engaged, on the position-limited wheel, be provided with the second guide groove, second guide groove is engaged with second guide rail.
The roller is fixed with first flange away from the end face of the door strap, and the position-limited wheel is away from the door strap End face is fixed with second flange.
Be provided with the first groove between first guide rail and the main body, the first flange and first groove it Between for gap coordinate;The second groove, the second flange and described second are provided between second guide rail and the main body Coordinate for gap between groove.
The noise reduction layer for preventing noise from producing is provided with first guide groove and the second guide groove.
The noise reduction layer is synthetic rubber.
The noise reduction layer includes the layer body of some different colours.
Using above technical scheme, this utility model achieves following technique effect:
(1) position-limit mechanism of the door strap that this utility model is provided, which ensure that door strap is moved on door guide rail bracket, And without departing from door guide rail bracket;
(2) first flange is set on the end face of roller, second flange is set on the end face of position-limited wheel, can be further Ensure that roller and position-limited wheel are moved without deviating from door guide rail bracket on door guide rail bracket;
(3) noise reduction layer is provided with roller and position-limited wheel, can prevent door strap from producing noise when sliding;
(4) noise reduction layer includes the layer body of some different colours, can be easy to when being worn discernable.

Specific embodiment
As Figure 1-Figure 4, the position-limit mechanism of this utility model door strap 4 includes a guide rail bracket 1, roller 2 and position-limited wheel 3, door guide rail bracket 1 includes main body 15 and the first guide rail 11 for being arranged in main body 15 and the second guide rail 12,11 He of the first guide rail Second guide rail 12 is in opposite direction, and roller 2 is each attached on door strap 4 with position-limited wheel 3, and the first guide groove 21 is provided with roller 2, the One guide groove 21 is engaged with the first guide rail 11, and the second guide groove 31, the second guide groove 31 and 12 phase of the second guide rail are provided with position-limited wheel 3 Coordinate.The position-limit mechanism of the door strap 4 that this utility model is provided, which ensure that door strap 4 is moved on door guide rail bracket 1, and And without departing from door guide rail bracket 1.
As shown in Fig. 2 the first groove 13 is provided between the first guide rail 11 and main body 15, the second guide rail 12 and main body 15 it Between be provided with the second groove 14, specifically, in this utility model, the first guide rail 11, the second guide rail 12, the first groove 13, second Groove 14 and body 15 are formed for panel beating one bending, and it is in Ω shapes that door guide rail bracket 1 is overall.As shown in figure 3, roller 2 is hung away from door The end face of plate 4 is fixed with first flange 22, coordinates for gap between first flange 22 and the first groove 13.Set in first guide groove 21 It is equipped with the noise reduction layer 5 for preventing noise from producing.As shown in figure 4, position-limited wheel 3 is fixed with second flange 32 away from the end face of door strap 4, Coordinate for gap between second flange 32 and the second groove 14, the noise reduction layer 5 for preventing noise from producing is provided with the second guide groove 31. First flange 22 and second flange 32 may further ensure that roller 2 and position-limited wheel 3 are moved without deviating from door guide rail bracket 1 Door guide rail bracket 1, is prevented from elevator door and is deviate from guide rail when impacting, it is ensured that elevator is safer in day-to-day operation, can Lean on.When roller 2 and position-limited wheel 3 are moved on guide rail door guide rail bracket 1, noise reduction layer 5 effectively reduces the noise produced during operation.
Wherein, noise reduction layer 5 can be synthetic rubber.Noise reduction layer 5 includes the layer body of some different colours being stacked.Cause Roller 2 and the long-term motion on door guide rail bracket 1 of position-limited wheel 3, can cause certain wear extent.Conventional repair and maintenance are very difficult to decision gate The performance of link plate 4, now when the such as synthetic rubber of noise reduction layer 5 of roller 2 and position-limited wheel 3 produces abrasion, tartan exposes separately One color, you can judge that the door strap 4 is undesirable, you can change roller 2 or position-limited wheel 3.
The slide opening for 3 adjusting position of position-limited wheel is additionally provided with door strap 4, facilitates installation to fix position-limited wheel 3, it is easy to scene Adjust 4 position of door strap.
Finally it should be noted that:Preferred embodiment of the present utility model is these are only, is not limited to practical It is new, although being described in detail to this utility model with reference to embodiment, for a person skilled in the art, its according to So the technical scheme described in foregoing embodiments can be modified, or equivalent is carried out to which part technical characteristic and replace Change, but it is all within spirit of the present utility model and principle, and any modification, equivalent substitution and improvements made etc. all should be included Within protection domain of the present utility model.
