Description
Technical field
The utility model relates to crane limiting device technical fields, and in particular to a kind of bridge crane lifting position-limit
Device.
Background technique
Crane limiter is a kind of safety device of bridge crane indispensability, for limiting the height of load-engaging device, when
Suspender rises when being raised to upper limit position, and limiter is cut off the power, prevent the load-engaging devices such as suspension hook continue to rise break wirerope and
Weight occurs and loses accident.
Currently, the limit method of bridge crane is weight and the double position limitation protections of spindle nose, traditional weight is limited in reality
There are many problems in use: weight, which is easily damaged, to fall off；Travel switch is due to pulling force downward by weight for a long time, the company of causing
Connection mechanism damage；Contact closure is bad to cause route virtual connection.The normal production that these problems not only affect enterprise also aggravates
The labor intensity of maintenance personnel, once failure occur, in order to not influence production will short envelope route, brought sternly to safety in production
It threatens again.
Utility model content
It is easily damaged to solve the weight of existing bridge crane limiter and falls off；Travel switch is due to for a long time by weight
Downward pulling force, causes bindiny mechanism to damage；Contact closure is bad to cause route virtual connection, not only affects the normal production of enterprise
Also aggravated the labor intensity of maintenance personnel, once failure occur, in order to not influence production will short envelope route, to safety in production
The problem of seriously threatening is brought, the utility model provides a kind of bridge crane lifting position-limit device.
In order to solve the above technical problems, the utility model provides the following technical solution:
A kind of bridge crane lifting position-limit device, including firm banking, detection bar and close switch；It is described solid close to switch
Determine on the fixed base；The detection bar is located at the top of the firm banking；The lower end connecting detection of the detection bar
Piece；The side of the firm banking is equipped with detection lug slideway；One end of the detection lug connects the fixation by elastomeric element
Pedestal；The other end of the detection lug is located in the slideway.
Further, the firm banking is equipped with fixed block；The fixed block is equipped with the set for being inserted in the detection bar
Ring guarantees the movement that detection bar can be stable.
Further, the close switch is vortex type proximity switch, vortex type proximity switch good in anti-interference performance, application
Range is wide, and price is lower.
Further, described to be bolted on the firm banking close to switch, facilitate installation
Further, the elastomeric element is spring, guarantees that detection lug is slowly and steadily moved with detection bar.
Compared with prior art, the beneficial effects of the utility model are as follows:
The bridge crane lifting position-limit device of the utility model, structure is simple, and contact-making switch and detection lug and detection bar join
Motivation structure use non-contact connection, avoid weight limit during, weight be easily damaged fall off, travel switch due to for a long time by
The pulling force downward to weight causes bindiny mechanism to damage and contact closure bad the problem of causing route virtual connection, guarantees production
The safety of process device and personnel.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also
Other attached drawings can be obtained with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model bridge crane lifting position-limit device；
Fig. 2 is schematic diagram when the utility model bridge crane lifting position-limit device uses.
In figure: 1, firm banking；2, close to switch；3, detection bar；4, detection lug；5, spring；6, detection lug slideway；7, solid
Determine block；8, lantern ring；9, wirerope；10, lead.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The utility model embodiment includes:
A kind of bridge crane lifting position-limit device as shown in Fig. 1, including firm banking 1, detection bar 3 and close switch
2；It is described to be fixed on the firm banking 1 close to switch 2；The detection bar 3 is located at the top of the firm banking 1；It is described
The lower end connecting detection piece 4 of detection bar 3；The side of the firm banking 1 is equipped with detection lug slideway 6；One end of the detection lug 4
The firm banking 1 is connected by elastomeric element；The other end of the detection lug 4 is located in the slideway 6.
Further, the firm banking 1 is equipped with fixed block 7；The fixed block 7 is equipped with and is inserted in the detection bar
Lantern ring 8 guarantees the movement that detection bar can be stable.
Further, the close switch 2 is vortex type proximity switch, and vortex type proximity switch good in anti-interference performance is answered
It is wide with range, and price is lower.
Further, described to be bolted on the firm banking 1 close to switch 2, facilitate installation
Further, the elastomeric element is spring 5, guarantees that detection lug is slowly and steadily moved with detection bar.
As shown in Fig. 2, when weight, which rises, reaches limit, wirerope 9 is moved to the left, and touches one end of detection bar 3, this
When, the detection bar other end moves in the opposite direction, and far from close to switch 2, switch opened point is disconnected, the rising connecting with lead 10
Circuit is cut off, and plays the role of lifting position-limit.
Compared with prior art, the beneficial effects of the utility model are as follows:
The bridge crane lifting position-limit device of the utility model, structure is simple, and contact-making switch and detection lug and detection bar join
Motivation structure use non-contact connection, avoid weight limit during, weight be easily damaged fall off, travel switch due to for a long time by
The pulling force downward to weight causes bindiny mechanism to damage and contact closure bad the problem of causing route virtual connection, guarantees production
