Description
Technical field
The utility model relates to a kind of hoisting crane, especially a kind of transfer crane anchoring device.
Background technology
It is high that transfer crane has utilization of area rate, scope of work is large, adapt to wide, the features such as highly versatile, be widely used in the outdoor locations such as goods yard, harbour, affect to produce by external force such as high wind after a shutdown for preventing hoisting crane and move, need to arrange wind-proof device, existing wind-proof device is generally wind-proof iron wedge, when hoisting crane is shut down, by on the track below iron drift ping to crane wheel, and jam-pack, during crane operating status, need to take out iron wedge under wheel, for large-tonnage hoisting crane, the iron wedge arranged is larger, heavier-weight, at this moment, manual operation is extremely required great effort, and placement is firm not, time one is long, the easy landing of iron wedge, crane windproof device is caused to lose efficacy, the generation of safety misadventure may be caused.
Utility model content
For solving above technical matters, the utility model provides a kind of easy to operate, the transfer crane anchoring device that reliability is high.
Its technical scheme is as follows:
A kind of transfer crane anchoring device, its main points are: comprise latch and be installed in the grappling bearing on hoisting crane cross sill, described grappling bearing is provided with the through hole suitable with latch, and this through hole is vertically arranged, and latch to stretch into below hoisting crane in ground through through hole slidably.Adopt above structure, utilize bearing pin to insert ground fixed crane, easy to operate, fixed, not easily deviate from, good reliability.
Preferably, described grappling bearing is provided with blind hole, and aperture and the latch of this blind hole are suitable.When normally working to facilitate hoisting crane, place bearing pin.
Preferably, described grappling bearing is provided with contact switch, the contact of this contact switch is positioned at below through hole, described contact switch and hoisting crane power supply chain, when latch inserts in through hole, this latch and contact, control to disconnect hoisting crane power supply, after extracting latch, contact switch controls the energising of hoisting crane power supply.This structure can prevent from operating personal from forgetting when manipulating crane extracting latch and start hoisting crane, causing the accident.
Preferably, described latch upper end is provided with the positive stop lug boss of annular, and the diameter of this positive stop lug boss is greater than through-hole aperture.To prevent latch transition from stretching in through hole, be inconvenient to take out.
Preferably, described latch upper end is provided with draw ring, is convenient to manual operation.
Beneficial effect:
Adopt the transfer crane anchoring device of above technical scheme, structure is simple, novel, is convenient to manufacture and install, and failure rate is low, reliability is high, long service life, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the I-I cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of transfer crane anchoring device as depicted in figs. 1 and 2, the grappling bearing 2 comprising latch 1 and be installed on hoisting crane cross sill 8, described grappling bearing 2 is provided with the through hole 3 suitable with latch 1 and blind hole 4, this through hole 3 is vertically arranged, and up/down perforation, blind hole 4 is arranged on through hole 3 side abreast, its upper end open, lower end closed, latch 1 passes through hole 3 slidably and stretches in the anchor block hole 7 on ground below hoisting crane, and anchor block hole 7 is embedded in ground concrete.
Described grappling bearing 2 is provided with contact switch 5, the contact 5a of this contact switch 5 is positioned at below through hole 3, and in the stroke range up and down of latch 1, described contact switch 5 is chain with hoisting crane power supply, when latch 1 inserts in through hole 3, this latch 1 contacts with contact 5a, controls to disconnect hoisting crane power supply, after extracting latch 1, contact switch 5 controls the energising of hoisting crane power supply.
Described latch 1 upper end is provided with the positive stop lug boss of annular, and the diameter of this positive stop lug boss is greater than through hole 3 aperture, and for convenience of operation, latch 1 upper end is provided with draw ring 6.
Principle of work of the present utility model is as follows:
Under hoisting crane off working state, latch 1 via through holes 3 is inserted in anchor block hole 7, positive stop lug boss abut with grappling bearing 2 end face carry out spacing, latch 1 contacts with contact 5a, and hoisting crane power supply disconnects, when needing to start hoisting crane, first latch 1 is extracted in through hole 3, put into blind hole 4, contact switch 5 is connected, and hoisting crane enters mode of operation.
Finally it should be noted that; foregoing description is only preferred embodiment of the present utility model; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing, such conversion all falls within protection domain of the present utility model.
