Description
Technical field
The utility model relates to a kind of elevator and drive system thereof.
Background technology
In jacking equipment and the elevator/hydraulic hoist field of the manned or cargo of several meters to more than 20 meters, tradition towed elevator/hydraulic hoist has the great number that equipment manufacturing cost and high rise elevator be more or less the same and drops into and maintenance cost, and its principle of design makes to obtain the maintenance of high levels and detects the higher safety factor of guarantee, although and hydraulic elevator/hydraulic lift cannot be applied in high rise elevator field at present, but the hydraulic elevator/hydraulic lift field of load capacity has the not replaceable preceence of other elevators in several meters to more than 20 meters hoisting depths, and more having some to have does not need the maintenance of high levels and detects just can ensure higher safety factor, equipment investment and maintenance cost lower, but the oil circuit of current hydraulic elevator/hydraulic lift both domestic and external and valve system complexity thereof, at least need the speed controlling function that two or more electro-hydraulic proportional valve just can complete elevator rising and decline, cause productive costs still higher, pipeline complexity also makes maintenance more difficult.
Utility model content
The utility model is intended to provide a kind of hydraulic elevator drive system, realizes elevator drive with better simply structure and lower cost.
Hydraulic elevator drive system in this programme, comprise housing, columniform cavity is provided with in housing, the cylindrical drive wheel of eccentric rotary is provided with in cavity, the both ends of the surface of drive wheel and the both ends of the surface bearing fit of cavity, the cylindrical wall of drive wheel and the inner round wall of cavity are kept in touch, the eccentrically weighted shaft of drive wheel overlaps with the center shaft of cavity, drive wheel is connected with dividing plate, the both sides of dividing plate and the two sides of cavity are slidably connected cavity to be divided into two parts, the free end of dividing plate is shipped and resell on another market through the sealing of rotating connection in housing, the both sides of the end face upper spacer of cavity are respectively equipped with oil inlet and oil outlet, drive wheel connects with its axis of rotation, rotating shaft is connected with axle drive shaft by crank through housing, axle drive shaft is connected with worm gear, the worm mesh that worm gear connects with drive motor output shaft.
Drive wheel continues eccentric rotary in the cavities, the hydraulic oil being flow to cavity by oil inlet under the extruding of drive wheel and dividing plate to oil outlet diffluence.Sealing is shipped and resell on another market and axle drive shaft place is provided with hermetically-sealed construction, avoids hydraulic oil to outflow.The draw bail of worm and gear ensure that auto-lock function realizes, and can not cause mechanism's involuntary maneuvers such as the drive wheel in this device because of the cut-back pressure of liquid, maintenance height stable after can realizing elevator hoist.This apparatus structure is compact, can realize hydraulic elevator driving work with lower cost.
Further, drive wheel is connected by bearing with its rotating shaft.To reduce operating friction.
Further, the periphery of axle drive shaft is provided with and connects capsul with housing.
Further, drive motor is change speed motor.To adjust actuating speed easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is A-A cutaway view when drive wheel is positioned at lowest part in Fig. 1 embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: housing 1, change speed motor 2, worm screw 3, worm gear 4, rotating shaft 5, capsul 6, crank 7, drive wheel 8, cavity 9, dividing plate 10, sealing ship and resell on another market 11, oil inlet 12, oil outlet 13.
Embodiment is substantially as shown in accompanying drawing 1,2: the right of housing is provided with change speed motor, change speed motor output shaft is connected with the worm screw of horizontal direction, the worm gear that screw rod and housing expose engages, the rotating shaft of worm gear to penetrate in capsul and is fixedly connected with crank, and the driven end of crank connects drive wheel by bar and bearing.
Columniform cavity is provided with in housing, the cylindrical drive wheel of eccentric rotary is provided with in cavity, the both ends of the surface of drive wheel and the both ends of the surface bearing fit of cavity, the cylindrical wall of drive wheel and the inner round wall of cavity are kept in touch simultaneously, flow with the hydraulic oil can pushed in cavity that rotates clockwise realizing drive wheel.The worm wheel shaft that drive wheel connects overlaps with the center shaft of cavity, drive wheel has been fixedly connected dividing plate, the width of horizontal direction upper spacer equals the width of cavity, the two sides of dividing plate both sides and cavity are slidably connected cavity to be divided into upper and lower two parts, the left end of dividing plate is shipped and resell on another market through the sealing of rotating connection in housing, seal the middle part of shipping and reselling on another market and be provided with the hole passed for dividing plate, the parts that sealing ships and resell on another market is in contact with it are and are closely slidably connected, ensureing movable while, also can prevent oil plant from leaking in a large number.The both sides up and down of the end face upper spacer of cavity are respectively equipped with oil inlet and oil outlet.
Drive wheel continues eccentric rotary in the cavities, the hydraulic oil being flow to cavity by oil inlet under the extruding of drive wheel and dividing plate to oil outlet diffluence.Sealing is shipped and resell on another market and axle drive shaft place is provided with hermetically-sealed construction, avoids hydraulic oil to outflow.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
