Abstract
A hydraulic buffer for an elevator comprises a hydraulic cylinder and a reset spring, wherein a piston of the hydraulic cylinder is sleeved with the reset spring. A clashing base is arranged at the top end of the piston, and one side of the hydraulic cylinder is fixedly connected with a switch which is connected with a switch knocking rod triggering the switch to be turned on and turned off. A sliding groove distributed along the periphery of the clashing base is formed in the lower portion of the clashing base, a sliding block which is matched with the sliding groove and can slide in the sliding groove freely is arranged inside the sliding groove, and the sliding block is fixedly connected to the switch knocking rod. According to the hydraulic buffer for the elevator, the switch knocking rod stands vertically all the time and cannot move or be deformed, the position of the switch knocking rod does not need to be reset by a person after the switch knocking rod is triggered by the buffer, and using is convenient. The hydraulic buffer for the elevator is simple in structure and low in cost.
Description
Technical field
The present invention relates to a kind of water bumper, be mainly used in elevator, belong to elevator and manufacture field.
Background technology
Water bumper is arranged on elevator hoistways bottom, when lift car or counterweight fall, can play last buffering, stop and protective effect, in order to avoid car directly hits at the end.Current water bumper as shown in Figure 1, switch is made bar and directly is fixed on the outer rim of spring perch, switch trigger gear is fixed on pressure cylinder simply, after water bumper is subject to lift car or counterweight shock, move down and move after while resetting, switch is made bar and is tended to deviation position, and serious meeting produces torsional deflection.Therefore, after the each effect of these hydraulic damping devices, all need manually to be adjusted, so that its recovery.
Summary of the invention
The present invention, for solving the prior art problem, provides a kind of hydraulic damper for elevator of long service life.
Technical scheme of the present invention is: a kind of hydraulic damper for elevator, comprise hydraulic actuating cylinder, and the piston upper reset spring that is placed on this hydraulic actuating cylinder, the top of described piston is provided with the head-on collision seat, one side of described hydraulic actuating cylinder is fixedly connected with switch, described switch is connected with the switch that triggers this switch folding and makes bar, the bottom of described head-on collision seat is provided with along the chute of described head-on collision seat circumferential distribution, be provided with the slide block that matches with this chute and can be free to slide in this chute in this chute, described slide block is fixedly connected on described switch and beats on bar.
As preferably, the stage casing that described switch is made bar is provided with guiding parts, and described switch is made bar and can vertically freely be moved up and down in this guiding parts; Described guiding parts is fixedly connected with described hydraulic actuating cylinder.
As preferably, described guiding parts comprises upper guide plate and the lower guide plate be parallel to each other from top to bottom successively, described upper guide plate be respectively arranged with upper pilot hole and lower pilot hole coaxial and that size is identical on lower guide plate, it is coaxial with described upper pilot hole and lower pilot hole respectively that described switch is made bar, and successively from described pilot hole and lower pilot hole pass.
As preferably, described slide block is beaten between bar and is connected by bolt with described switch.
As preferably, the cross-sectional plane of described chute is rectangle.
As preferably, the rectangle of the axial cross section of described slide block for matching with described chute.
As preferably, the radial section of described slide block is circular.
Traditional hydraulic damping device is when being knocked, and spring is compressed, and traditional spring structure makes spring can produce the moment of torsion of a rotation in compression process, and this moment of torsion can directly act on switch and make bar, makes switch make bar and produces displacement, even distortion.In the present invention, when car or counterweight clash into the head-on collision seat on water bumper top, spring is compressed, and the head-on collision seat rotates under the torsional interaction of spring, but switch is made bar and the slide block be fixedly connected with it can slide mutually with the head-on collision seat, and maintenance is vertically motionless; And guiding parts further guaranteed switch beat bar vertically.
In sum, the present invention has the following advantages:
1, switch is made bar and is remained and vertically can not produce displacement and distortion, and energy disperser does not need manual reset after triggering, easy to use;
2, simple in structure, with low cost.
The accompanying drawing explanation
Fig. 1 is traditional water bumper structural representation;
Fig. 2 is water bumper structural representation of the present invention.
In figure, 1, hydraulic actuating cylinder, 11, piston, 2, retracing spring, 3, switch, 4, switch makes bar, 41, slide block, 42, bolt, 5, the head-on collision seat, 51, chute, 6, guiding parts, 61, upper guide plate, 62, lower guide plate.
