Abstract
An aerial ropeway carriage anti-swing device arranged between a large carriage suspension bracket and a walking trolley mainly consists of a walking trolley (7), a trolley shaft (12), a hydraulic control loop (3) and a swing hydraulic cylinder (4). The hydraulic control loop (3) is connected with the swing hydraulic cylinder (4) by a pipeline; a gear (14) mounted on an output shaft (5) is arranged in the swing hydraulic cylinder (4). Two inner cavities are arranged in the swing hydraulic cylinder (4); a piston (13) processed with racks is arranged in the inner cavities and is articulated with the gear (14); an output shaft (5) is connected with the trolley shaft (12). When the carriage arranged on a bearing cable (1) swings along the running direction, a torque T generated by the carriage (2) is transferred to the swing hydraulic cylinder (4) by the trolley shaft (12); a piston in the high pressure oil cylinder of the swing hydraulic cylinder is acted by liquid force and leads the output shaft of the swing hydraulic cylinder to generate a torque T' by the gear for realizing the anti-swing of the carriage (2).
Description
Technical field
What the present invention relates to is that aerial rope way is in operation and prevents the device swung, particularly a kind of antiswing device for overhead cableway compartment body of being provided with between large-scale envelope suspension bracket and the walking dolly of being used for.
Background technology
The envelope antiswing device is the requirement as the mandatory specific technique of safety standard, fails at present thoroughly to solve always.All kinds of envelope antiswing devices that existing domestic design is produced have: mechanical type such as spring shimmy-damper be because the restriction of buffering elastomeric material performance, has critical defects such as low and dynamic adjustable difference in service life.Fluid pressure type such as hydraulic actuating cylinder suspension type are anti-sway, because the frequent variations of piston motion strained condition very easily causes oil cylinder leakage of oil poor reliability, the maintenance cost height.What abroad adopt is the reciprocating type oscillating motor, and its cost is higher than 10 times more than of double rack formula hydraulic actuating cylinders, and domestic can't the maintenance.
Summary of the invention:
The technical matters that solves
The technical problem to be solved in the present invention provides a kind of antiswing device of aerial rope way envelope.It adopts two-cylinder type pinion and-rack hydraulic actuating cylinder hydro-cushion mode in pressurize aneroid potential source (oil pump) system to prevent the envelope swing.Envelope on being installed in ropeway carrying-rope occurs following when sailing the direction swing, and the torque T that envelope produced passes to oscillating motor by little axletree.Piston is subjected to the fluid power effect in the high-voltage oil cavity of oscillating motor at this moment, makes the output shaft of oscillating motor produce resisting moment T ' by gear, thereby realizes the anti-sway of envelope.
Technical scheme
In order to solve deficiency of the prior art, technical solution of the present invention is: antiswing device mainly is made up of walking dolly, little axletree, hydraulic control circuit and oscillating motor, hydraulic control circuit is connected with oscillating motor by pipeline, gear is housed on the output shaft places hydraulic cylinder, oscillating motor is provided with two inner chambers, be processed with tooth bar on the piston and place inner chamber, with gear mesh, output shaft is connected with the dolly axle.By governor valve in the modulated pressure control loop, export a road high pressure oil and b road low pressure oil respectively, the flow of hydraulic oil carries out stepless adjustment between the high-low pressure oil pocket of oscillating motor body inside to flowing through.
Beneficial effect
The antiswing device of aerial rope way envelope provided by the present invention adopts the reverse operating characteristic of twin-tub gear rack type swing hydraulic actuating cylinder to be applied to the anti-oscillator system of the medium-and-large-sized envelope of aerial rope way.It is big to have damping moment of torsion responding range; Rational in infrastructure, make, install, repair easily, characteristics such as cost is low.Design, production and safe operation for large-scale cableway envelope simultaneously provides reliable assurance.

The specific embodiment:
Below in conjunction with accompanying drawing in detail the present invention is described in detail.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 show integral structure of the present invention.Comprise the walking dolly 7, dolly axle 12, hydraulic control circuit 3 and the oscillating motor 4 that are installed on the ropeway carrying-rope 1, the output shaft 5 of oscillating motor 4 connects with dolly axle 12 by coupler 6,11, and the cylinder body of oscillating motor connects with walking dolly 7 by fastening locations 8,10 and sleeve 9.When envelope 2 runs into the state of kinematic motion variation in the process of moving, occur following and sail the direction swing, produce torque T and pass to oscillating motor 4 by dolly axle 12.At this moment, the piston 13 of band tooth bar is subjected to the fluid power effect in the high-voltage oil cavity 15 of oscillating motor, makes the output shaft 5 of oscillating motor produce resisting moment T ' by gear 14, thereby realizes the anti-sway of envelope.Hydraulic control circuit 3 is connected with oscillating motor 4 by pipeline, and hydraulic control circuit 3 mainly is made up of pressure gauge isolator valve 17, bladder accumulator 18, governor valve 20, by pass valve 21 and check valve 22.Concrete implementation step is: set up by pass valve 21 response pressures, bladder accumulator 18 charges into nitrogen in advance, fill to system with hand oil pump 19 and to add hydraulic oil, when the compression indicator number of degrees on being connected on pressure gauge isolator valve 17 reach certain pressure, remove hand oil pump 19, and check the sealing situation of whole hydraulic efficiency pressure system, guarantee that whole hydraulic efficiency pressure system must not leak.Pass through to adjust governor valve 20 in the use, export a road high pressure oil and b road low pressure oil respectively, control enters into the flow on oscillating motor 4 a ' road and b ' road from pipeline, thereby can carry out stepless adjustment to the flow of flow through oscillating motor 4 high- voltage oil cavities 15 and 16 hydraulic oil of low pressure oil pocket.Realization because of the adjustment of the moment T that produced of swing with the damping square T ' pay-as-you-go operation time of oscillating motor output shaft 5 generations, reaches the control to envelope amplitude of fluctuation and cycle to envelope 2.
