Detailed description of the invention
It is described in further detail in conjunction with the drawings and specific embodiments technical scheme required for protection to this utility model.
See shown in accompanying drawing 1 to accompanying drawing 5, a kind of automatic elasticity bolt device for tower crane of the present embodiment, including the commutation spanner 1 coordinated with bolt, for driving this commutation spanner 1 around the driving oil cylinder 2 of bolt axis oscillating, for installing the cylinder installation seat 3 driving oil cylinder 2 and the spanner bracket for the spanner 1 that commutates described in support.The piston rod wherein driving oil cylinder 2 is hinged with commutation spanner 1, and its jointed shaft is parallel with the axis of bolt；The cylinder body of this driving oil cylinder 2 is rotationally connected with cylinder installation seat 3, and its rotating shaft is parallel with the axis of bolt.
Commutation spanner 1 described in the present embodiment includes wrench body 11, it is rotationally connected with the bolt collar 12 of wrench body 11 head, it is built in the regulating part 13 of wrench body 11 head, the periphery of described bolt collar 12 is formed with a circle ratchet 121 so that bolt collar 12 constitutes ratchet structure, the ratchet 132 of a pair symmetrical cooperation ratchet 121 it is formed with on described regulating part 13, these regulating part 13 both sides form the regulation fork 131 extended to outside wrench body 11 the most respectively a pair, it is additionally provided with inside wrench body 11 for pushing up the ball 15 that pressure regulating part 13 back makes ratchet 132 automatically and ratchet 121 is conflicted and the back-moving spring 14 promoting this ball 15 simultaneously；Drive corresponding side ratchet 132 to conflict with ratchet 121 by regulation fork 131 thus limit bolt collar 12 and rotate with corresponding direction.
When the automatic elasticity bolt device of the present embodiment tights a bolt, first allow the bolt collar 12 of commutation spanner 1 be enclosed within bolt, and utilize spanner bracket that this commutation spanner 1 is carried out support；The wherein side fork 131 of commutation spanner 1 regulating part 13 is swung and puts in place so that it is the side ratchet 132 of correspondence is conflicted with the ratchet 121 of bolt collar 12 periphery, thus allow regulating part 13 and bolt collar 12 constitute click 132 mechanism of one-directional rotation.Commutation spanner 1 reciprocating swing under the driving driving oil cylinder 2, wherein when the swaying direction of the spanner 1 that commutates is identical with the rotation direction of bolt collar 12, bolt collar 12 relatively rotates with wrench body 11, and the bolt in bolt collar 12 remains stationary as；When the swaying direction of the spanner 1 that commutates is different from the rotation direction of bolt collar 12, bolt collar 12 rotates with wrench body 11, and the bolt in bolt collar 12 is tightened therewith；Bolt is made constantly to tighten during driving the continuous reciprocal telescopic of oil cylinder 2.
When the automatic elasticity bolt device of the present embodiment loosers a bolt, the opposite side fork 131 of commutation spanner 1 regulating part 13 is swung and puts in place, make the opposite side ratchet 132 of its correspondence conflict with the ratchet 121 of bolt collar 12 periphery, thus allow regulating part 13 and bolt collar 12 constitute click 132 mechanism of one-directional rotation.Commutation spanner 1 reciprocating swing under the driving driving oil cylinder 2, wherein when the swaying direction of the spanner 1 that commutates is identical with the rotation direction of bolt collar 12, bolt collar 12 relatively rotates with wrench body 11, and the bolt in bolt collar 12 remains stationary as；When the swaying direction of the spanner 1 that commutates is different from the rotation direction of bolt collar 12, bolt collar 12 rotates with wrench body 11, and the bolt in bolt collar 12 is unscrewed therewith；Bolt is made constantly to unscrew during driving the continuous reciprocal telescopic of oil cylinder 2.
The automatic elasticity bolt device of the present embodiment, compared with traditional manpower elasticity bolt mode, not only can be saved manpower and improve efficiency, and the degree of tightening of bolt is higher, and the structure making tower crane is more stable.
The embodiment of the above is only preferred embodiment of the present utility model, and this utility model not does any pro forma restriction.Any those of ordinary skill in the art, without departing under technical solutions of the utility model ambit, technical solutions of the utility model are made more possible variation and retouching by the technology contents that all may utilize the disclosure above, or are revised as the Equivalent embodiments of equivalent variations.Therefore all contents without departing from technical solutions of the utility model, the equivalent equivalence change made according to the thinking of this utility model, all should be covered by protection domain of the present utility model.
