Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of hoisting crane shock absorber.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.Also known as crane.Current domestic each large lifting Guangdong remy hair weight-lifting equipment Co., Ltd cancellation lift heavy driving functions gradually.For ensure job safety, at present domestic substantially forbid not making a jack carry out lifting operation.Nowadays, the traveling gear speed of travel of hoisting crane becomes more and more faster, its run safety, reliability want the more and more higher of changes persuing, road wheel needs buffer deceleration when stopping operation, traditional shock absorber is rubber block, be fixed to ad-hoc location, after contacting with road wheel, play the effect slowed down with damping, finally make road wheel slowly stop.But traditional yielding rubber block exists certain defect in use, occurs the generation of sliding phenomenon during cushion task, cause elevator machinery can not be out of service fast, there is potential safety hazard.
Therefore, it is simple, easy to operate to produce a kind of structure, work and operating efficiency high, safety factor is high, drag successful, the hoisting crane shock absorber that level of mechanization is high, has market outlook widely.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of structure simple, easy to operate, work and operating efficiency high, safety factor is high, drag successful, the hoisting crane shock absorber that level of mechanization is high.With solving in prior art the potential safety hazard in weight-lifting equipment walking.
The technical solution of the utility model is achieved in that a kind of hoisting crane shock absorber, comprise base plate, the fixing pedestal be fixedly mounted on base plate, described fixing pedestal is installed with pivot shaft, the side of pivot shaft is movably installed with telescopic block, pivot shaft between telescopic block and fixing pedestal is set with coil tension spring, be installed with return axle in telescopic block upper inner, the interior of return axle is installed with reinforcement inhibiting device.
Described reinforcement inhibiting device comprises the clump weight be fixedly mounted on base plate, clump weight is provided with S. A., S. A. is set with swivel mount, is installed with reinforcement postive stop baffle above swivel mount.
Described fixing pedestal top offers return hole, and return axle is movably arranged in this return hole, and described telescopic block bottom is provided with telescopic hole, and telescopic block is movably arranged on pivot shaft by this telescopic hole.
The outside of described telescopic block is installed with the first damping rubber block, and the first described damping rubber block obtains outside for groove-like structure.
The outside of described reinforcement postive stop baffle is installed with the second damping rubber block, is provided with flexible stay cord between described reinforcement postive stop baffle and clump weight.
The utility model has following good effect: first this product structure is simple, easy to operate, fixing pedestal is installed with pivot shaft, the side of pivot shaft is movably installed with telescopic block, pivot shaft between telescopic block and fixing pedestal is set with coil tension spring, return axle is installed with in telescopic block upper inner, the interior of return axle is installed with reinforcement inhibiting device, in use, the contractility of spring is utilized jointly to realize the stop to wheel with the obstruct power strengthening postive stop baffle, the shock dynamics of wheel and speed are more large faster, the sinking speed strengthening postive stop baffle is also faster, wheel clashes into reinforcement postive stop baffle direction, the stability strengthened after postive stop baffle landing is stronger, realize clashing into wheel the quick reduction of speed and buffer action that combine, base plate and fixing pedestal remain invariant position, greatly provide work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model running state structural representation.
Detailed description of the invention
As shown in Figure 1, 2, a kind of hoisting crane shock absorber, comprise base plate 1, the fixing pedestal 3 be fixedly mounted on base plate 1, described fixing pedestal 3 is installed with pivot shaft 6, the side of pivot shaft 6 is movably installed with telescopic block 2, pivot shaft 6 between telescopic block 2 and fixing pedestal 3 is set with coil tension spring 7, is installed with return axle 5 in telescopic block 2 upper inner, the interior of return axle 5 is installed with reinforcement inhibiting device.
Described reinforcement inhibiting device comprises the clump weight 8 be fixedly mounted on base plate 1, clump weight 8 is provided with S. A. 9, S. A. 9 is set with swivel mount 10, is installed with and strengthens postive stop baffle 11 above swivel mount 10.Described fixing pedestal 3 top offers return hole, and return axle 5 is movably arranged in this return hole, and described telescopic block 2 bottom is provided with telescopic hole, and telescopic block 2 is movably arranged on pivot shaft 6 by this telescopic hole.The outside of described telescopic block 2 is installed with the first damping rubber block 4, and it is groove-like structure that the first described damping rubber block 4 obtains outside.The outside of described reinforcement postive stop baffle 11 is installed with the second damping rubber block 12, is provided with flexible stay cord 13 between described reinforcement postive stop baffle 11 and clump weight 8.
This product in use, after the wheel 14 that running gear 15 is installed strikes the first damping rubber block 4, first damping rubber block 4 is to after contraction, play buffer action, coil tension spring 7 shrinks, simultaneously, return axle 5 moves backward, touch with bottom swivel mount 10, make swivel mount 10 left-hand revolution, strengthen postive stop baffle 11 to fall, second damping rubber block 12 drops on the side when running gear 15, form buffer action, utilize coil tension spring 7, first damping rubber block 4 and the second damping rubber block 12 apply buffer deceleration to wheel 14 jointly, substantially increase work efficiency, base plate 1 and clump weight 8 ensure the stability of product self.There is good Social and economic benef@.
