Abstract
The utility model relates to a range limiter, including stop device and connecting device, stop device includes micro -gap switch, guide bar, uide bushing, split damping ring, direction head and compression spring. The inner chamber wall of uide bushing right -hand member is connected with compression spring's right -hand member, and the left end is connected with the direction head, is equipped with guide bar and compression spring in the uide bushing, split damping ring installs the part that is located the uide bushing intracavity at the guide bar. Spring pocket is on the guide bar, and compression spring's left end is connected with split damping ring. Connecting device includes connecting plate and fillister head screw, the uide bushing is fixed in on the connecting plate, micro -gap switch passes through fillister head screw to be fixed on the connecting plate. The utility model provides a current range limiter installation and debugging expect much, require the processing of work piece also high, proximity switch's the problem that installation space is big simultaneously.
Description
Technical field
The utility model relates to matching used distance caging device on a kind of lifting machine.
Background technology
The matching used inhibiting device of lifting machine refers to the highest limit switch in auto hoist lifting process.Prior art is proximity switch, and proximity switch is a kind of induction metal type switch, and the assemblage gap of sensitive surface requires within 4mm, and exceeding this scope will lose efficacy; Therefore Installation and Debugging require high, also high to the processing request of workpiece, and the installing space of proximity switch is large simultaneously, and this just needs to research and develop matching used distance caging device on new-type lifting machine.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of distance caging device.Use this distance caging device stroke large, be convenient to Installation and Debugging, reduce costs, can fault rate be reduced.
In order to solve this technical matters, the utility model by the following technical solutions:
A kind of distance caging device, comprise inhibiting device and connecting device, described inhibiting device comprises micro-switch, pilot bar, orienting sleeve, split washer, guide head and Compress Spring.Orienting sleeve is built with pilot bar and Compress Spring, and described Compress Spring cover on the guide bar; The internal chamber wall of orienting sleeve right-hand member is connected with the right-hand member of Compress Spring, and left end is connected with guide head.Described orienting sleeve is provided with the through hole matched with pilot bar.Described split washer is arranged on the part that pilot bar is positioned at guiding mantle cavity.The left end of described Compress Spring is fixedly connected with split washer; Described guide head is provided with the through hole matched with pilot bar.Described connecting device comprises connecting panel and dish screw, and described orienting sleeve is welded on connecting panel, and described micro-switch is fixed on connecting panel by dish screw, is provided with a shake-up spring leaf below micro-switch.
Be threaded connection between described guide head and orienting sleeve.
The junction of described pilot bar and split washer is provided with groove, and beginning back-up ring is fixed on the groove of pilot bar in a snap-in manner.
Good effect of the present utility model is: it is simple that the utility model has structure, is convenient to Installation and Debugging, and stroke is large, simple to the processing request of workpiece, reduces the installing space of inhibiting device simultaneously, reduces costs, can reduce the advantage of fault rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of distance caging device, supporting the use for lifting machine, comprises inhibiting device and connecting device, and described inhibiting device comprises micro-switch 2, pilot bar 3, orienting sleeve 4, split washer 5, guide head 6 and Compress Spring 7.Orienting sleeve 4 is built with pilot bar 3 and Compress Spring 7, and the internal chamber wall of described orienting sleeve 4 right-hand member is connected with the right-hand member of Compress Spring 7, and left end is connected with guide head 6, and orienting sleeve 4 is provided with the through hole matched with pilot bar 3.Described split washer 5 is arranged on the part that pilot bar 3 is positioned at orienting sleeve 4 chamber.Described pilot bar 3 is provided with groove with the junction of split washer 5, and split washer 5 is fixed on the groove of pilot bar 3 in a snap-in manner.Described Compress Spring 7 is enclosed within pilot bar 3, and the left end of Compress Spring 7 is connected with split washer 5.Described guide head 6 is threaded connection with orienting sleeve 4, and guide head 6 is provided with the through hole matched with pilot bar 3.Described connecting device comprises connecting panel 1 and dish screw 8, and described orienting sleeve 4 is welded on connecting panel 1.Described micro-switch 2 is fixed on connecting panel 1 by dish screw 8.Be provided with a shake-up spring leaf 9 below micro-switch 2, the keying of micro-switch 2 when touching spring leaf 9 action, can be realized.
Distance caging device is fixed on the base of lifting machine by connecting panel 1, when the folding arm of lifting machine extends, slide to the right along base in the mobile terminal of telescopic boom, the mobile terminal of telescopic boom touches the left end of pilot bar 3 when sliding into certain position, and slide to the right the while of promoting pilot bar 3, in the process, split washer 5 promotes Compress Spring 7 and shrinks gradually, when the right-hand member of pilot bar 3 touches the shake-up spring leaf 9 of micro-switch 2, micro-switch 2 becomes closed condition from opening, the folding arm of lifting machine stops extending, and lifting machine reaches requirement height.
When the folding arm of lifting machine shortens, slide left along base in the mobile terminal of telescopic boom, pilot bar 3 and split washer 5 reset gradually under the promotion of Compress Spring 7, when the right-hand member of pilot bar 3 does not contact with the shake-up spring leaf 9 of micro-switch 2, micro-switch 2 becomes opening from closed condition, final split washer 5 contacts with guide head 6 under the effect of Compress Spring 7, and reset completes.
