Abstract
The utility model relates to auxiliary devices of a bridge crane, in particular to deviation-preventive protecting device for the bridge crane. The deviation-preventive protecting device comprises a support (6) mounted on the shell of a reel (7) of the bridge crane, an intermediate relay (5) and a deviation switch (4) are mounted in the support (6), the bottom of a deviation spring (8) of the deviation switch (4) is fixedly connected with a horizontally-arranged steel wire ring (3), and a steel wire rope (2) wound on the reel (7) penetrates the steel wire ring (3). The deviation-preventive protecting device is reasonable in design and simple in structure; through proper change on a control loop of the bridge crane, deviation fault of the crane can be effectively avoided by additionally arranging the deviation prevention protecting device for a crank hook.
Description
Technical field
The utility model relates to the auxiliary device of crane in bridge type, specifically the anti-deflection fender guard of a kind of crane in bridge type.
Background technology
Crane in bridge type is a kind of weight-lifting equipment that industrial place, workshop extensively adopt, when lifting material, due to the misoperation of operating personal, as lifting material and reel out of plumb, suspension hook oblique pull material etc.Be easy to occur suspension hook sideslip, cause hoisting wirerope to depart from center, when steel rope departs from center to certain limit with regard to there will be rope guide to break or ineffective, steel rope and reel shell between wearing and tearing add tool and the faults such as disorder cable or distortion.
Summary of the invention
Often there is the problem of deflection in order to solve the steel rope of current crane in bridge type in the utility model, provide a kind of crane in bridge type anti-deflection fender guard in lifting process.
The utility model is to adopt following technical scheme to realize:
The anti-deflection fender guard of a kind of crane in bridge type; comprise the support on the reel shell that is installed on crane in bridge type; intermediate relay and deviation switch are installed on described support; the sideslip spring bottom of described deviation switch is fixed with the steel wire ring of horizontal positioned, the steel wire penetrating steel wire ring being wound around on described reel.
During use, as shown in Figure 1, control loop at hoisting crane seals in the open contact SQ of intermediate relay coil ZJ, deviation switch, the normally closed contact ZJ1 of intermediate relay, be open contact SQ and the rear direction control circuit parallel connection that forms series arm and hoisting crane of intermediate relay coil ZJ series connection of deviation switch, direction control circuit is the up, down, left, right, before and after control loop in Fig. 1; Then the normally closed contact ZJ1 of intermediate relay is connected between the lower control loop and left control loop of hoisting crane, as shown in Figure 1.When tiltedly hanging appears in the misoperation of operating personal; suspension hook and steel rope are along with deflection appears in the oblique pull of material; make steel wire ring horizontal displacement; the sideslip spring of deviation switch is bent, drive the open contact SQ of deviation switch closed, the coil ZJ of intermediate relay obtains electric; the normally closed contact ZJ1 of intermediate relay disconnects; crane in bridge type now, only to operate up and down, cannot carry out the operation of left-right and front-back, plays the anti-deflection protection of crane in bridge type and acts on.
The utility model is reasonable in design, simple in structure, by the control loop to crane in bridge type, suitably changes, and installs the anti-deflection fender guard of crane hook additional and can effectively avoid hoisting crane to occur deflection fault.
Accompanying drawing explanation
Schematic circuit diagram when Fig. 1 is the utility model use.
Fig. 2 is structural representation of the present utility model.
In figure, 1-suspension hook, 2-steel rope, 3-steel wire ring, 4-deviation switch, 5-intermediate relay, 6-support, 7-reel, 8-sideslip spring.
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The anti-deflection fender guard of a kind of crane in bridge type; as shown in Figure 2; comprise the support 6 on reel 7 shells that are installed on crane in bridge type; intermediate relay 5 and deviation switch 4 are installed on described support 6; sideslip spring 8 bottoms of described deviation switch 4 are fixed with the steel wire ring 3 of horizontal positioned, and the steel rope 2 being wound around on described reel 7 is through steel wire ring 3.
During concrete enforcement, described support 6 is L-type angle bar.
By the control loop of hoisting crane that Fig. 1 is shown in, seal in the open contact SQ of intermediate relay coil ZJ, deviation switch, the normally closed contact ZJ1 of intermediate relay.
By being connected with deviation switch 4 by L-type angle bar on the shell of reel that Fig. 2 is shown in 7, between the lower end of the sideslip spring 8 of deviation switch 4 and hoisting wirerope 2, be provided with steel wire ring 3.
Intermediate relay 5 is fixed on L-type angle bar 6.
Claims (2)
1. the anti-deflection fender guard of crane in bridge type; it is characterized in that: comprise the support (6) on reel (7) shell that is installed on crane in bridge type; intermediate relay (5) and deviation switch (4) are installed on described support (6); sideslip spring (8) bottom of described deviation switch (4) is fixed with the steel wire ring (3) of horizontal positioned, and the upper steel rope (2) being wound around of described reel (7) is through steel wire ring (3).
2. the anti-deflection fender guard of crane in bridge type according to claim 1, is characterized in that: described support (6) is L-type angle bar.
