Abstract
The utility model discloses a hydraulic buffer with good buffer performance and relates to the technical field of elevator accessories. The hydraulic buffer with good buffer performance comprises a base of a square structure. Connecting screw holes are formed in the four corners of the base and used for installing the base. An outer cylinder body is arranged in the middle of the upper portion of the base, a piston rod is installed in the outer cylinder body, and an anti-collision block is installed at the upper end of the piston rod. The anti-collision block is made of polyurethane material and thus is good in abrasion resistance and hardness. A positioning ring is arranged on the periphery of the anti-collision block, the piston rod is sleeved with a buffer spring, the upper end of the buffer spring abuts against the positioning ring, the lower end of the buffer spring abuts against the outer cylinder body, and thus the buffer spring can be positioned and prevented from shifting after making telescopic movement for a long time, and the buffer effect cannot be affected. The hydraulic buffer with good buffer performance is simple in structure and reasonable in design, the buffer spring can be positioned on multiple surfaces, the buffer effect can be improved, the service life of the buffer can be prolonged, the hydraulic buffer has very good economic benefits, and running safety of an elevator is also guaranteed.
Description
Technical field
The utility model relates to elevator accessory technical field, is specifically related to the water bumper that a kind of cushion characteristic is good.
Background technology
For the water bumper of the equipment such as elevator, to utilize hydraulic damping effect to carrying out buffer deceleration to stopping at car or counterweight that doing coast, be that elevator is while surmounting bottom or top layer, car or counterweight cushion at collision, absorb or consume the energy of elevator by energy disperser, thereby make car or counterweight be decelerated to and stop safely.General energy disperser is all arranged in melt pit, and some energy dispersers are loaded on car or the operation thereupon of counterweight bottom, therefore, in pit, the bearing that is highly at least 0.5m must be set.Forcibly driving elevator, the energy disperser that also should can work at the upper limit position of stroke car top setting.As counterweight is housed, and should be after counterweight buffer be fully compressed, just make to be loaded on the energy disperser effect of car upper.
The basic functional principle of water bumper is: when car or counterweight cushion at collision, piston rod moves downward, hydraulic oil in compression inner casing, hydraulic oil is overflow to outer shell by cutoff port, in stop car or counterweight process, its kinetic transformation is the heat energy of hydraulic oil, consumed the kinetic energy of elevator, elevator is stopped gradually with certain deceleration/decel, when the hydraulic oil liquid level in outer shell is during higher than piston upper surface, hydraulic oil flows into from the cutoff port of top the inner casing partial interior that is positioned at piston top simultaneously.When car or counterweight leave energy disperser, piston rod upwards resets under the effect of retracing spring, and hydraulic oil is back to internal and external equilibrium state.
The weak point that the water bumper of prior art mainly exists has: owing to only designing the cutoff port of some at inner casing, but the oil spillage during in actual use due to throttling is fixed, thereby not thering is universality, the elevator of different payload ratingies and command speed need to be equipped with the water bumper of different oil spillages; In addition, due to cutoff port skewness, thereby cause in buffering course, having the inhomogeneous problem of buffering stop power, have the inhomogeneous problem of deceleration/decel.
Therefore, need to develop and aly not only have universality but also can guarantee the inhomogeneity water bumper of deceleration of elevator degree, to solve the deficiencies in the prior art, the safety in operation that improves elevator also reduces costs input.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and practicality is good, the water bumper that cushion characteristic is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The water bumper that a kind of cushion characteristic is good, comprise the base of a square structure, four corners at described base are provided with connecting screw hole, for realizing the installation of base, described base upper middle position is provided with outer cylinder body, in described outer cylinder body, piston rod is installed, described piston rod upper end is provided with an anticollison block, this anticollison block is that polyurethane material is made, resistance to abrasion is good, hardness might as well, described anticollison block is arranged with certain position ring outward, described piston rod outer cover is provided with a recoil spring, described recoil spring upper end props up steady ring, lower end is against on outer cylinder body, realize the location to recoil spring, prevent that recoil spring is being offset after fore and aft motion for a long time, affect buffering effect.
Described anticollison block is cylindrical structural, and steady ring is fixed on anticollison block.
Described steady ring bilateral symmetry is provided with engaging lug, in the middle of described engaging lug, is provided with a through hole, is equipped with a positioning rod, for recoil spring side is positioned in this through hole.
Described radius stay bottom is fixed on outer cylinder body outer wall.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, can form the multiaspect location to recoil spring, improve buffering effect, in the service life that extends energy disperser, have extraordinary economic benefit, also guaranteed the safe in operation of elevator.
