Abstract
The utility model relates to a hydraulic double-operating rod switching machine which is suitable for switching and locking the double slip switch point rail part of a railway, a subway and a light railway and reflecting the positions and states of point rails. The hydraulic double-operating rod switching machine comprises a hydraulic station, a switching machine, an oil pipe, a protecting facility, and the like. The hydraulic double-operating rod switching machine is characterized in that in the switching machine, a double-oil cylinder double-operating rod (8,8') respectively draws the point rails (1and 3) and the point rails (2 and 4) of a double slip switch, and the safety index of the unlocking switch in 4mm is easily ensured by reducing traction force; the double-operating rod (8,8') has the asynchronous exceeding prevention function and can realize the differential motion of the double-operating rod in the specified range, and a differential value can be designed according to the requirement; two indication rods (9,9') respectively connect and express the states of the point rails (1and 3) and the point rails (2 and 4) and are universal when the switching machine switches between the left extension and the right extension; both ends of a shell of the switching machine are provided with adjustable spring positioning devices for positioning oil cylinders and preventing the rebound and shift of the oil cylinders after arriving; a mechanical hand rocking device is installed in the machine and can realize mechanical hand rocking operation when a hydraulic system is failed; and in order to be convenient for scene adjustment and maintenance, the mechanical hand rocking device has the respective operating function of the double-operating rod.
Description
(1) technical field: a kind of Hydraulic Double throw rod switch machine, be applicable to Railway Electric cluster field track switch, conversion, locking track switch moving part also reflect its position and state, are installed on track switch one side, are specially adapted to double slip switch tongue part.
(2) background technology: double slip switch is widely adopted with the advantage that it takes up an area of less, the conveying efficiency of shunting is high all the time.Existing domestic double slip switch tongue part all adopts the unit single pole to draw the mode of four tip of a root rails, and double slip switch, tongue mostly is a pin-connected panel, rigidity is little, adjust difficulty, maintenance workload is big, and because the switch machine tractive force is big, make 4 millimeters not the safety index of locking can not guarantee, cause potential safety hazard to transportation.
(3) summary of the invention: the utility model purpose provide a kind of overcome in the existing track switch traction technique can not guarantee 4 millimeters not Hydraulic Double throw rod switch machines of locking requirement defective, it is made of the Hydraulic Station that is installed on track switch one side, switch machine, erecting device, oil pipe, protective equipment etc., Hydraulic Station provides hydraulic power by oil pipe for Hydraulic Double throw rod switch machine, the position and the state of the conversion of Hydraulic Double throw rod switch machine, locking, expression track switch.Hydraulic Double throw rod switch machine is the two throw rods of two oil cylinders, draws 1,3 and 2,4 four tip of a root rails of slip switch respectively because the throw rod tractive force reduces, make 4 millimeters at track switch not the requirement of locking realize easily; Two throw rods are provided with the anti-asynchronous mechanism of moving, and can realize that two throw rods are differential in specialized range, and differential values can design as requested; Adopt two indication rods to connect and represent 1,3 and 2,4 tongue states respectively, wherein on every indication rod except that an angle is arranged, also have one big straight mouthful, two indication rods are general when stretching conversion about switch machine; At switch machine housing two ends the adjustable spring that oil cylinder is located is housed and decides power apparatus, prevented bounce-back and play after oil cylinder puts in place; With mechanical manual setter was housed in opportunity, constitute Hydraulic Double throw rod switch machine.When the utility model Hydraulic Double throw rod switch machine was layed on the track switch, existing switch control circuit was constant.
The utility model has following characteristics compared to existing technology:
1, by the design of the two throw rods of two oil cylinders, reduced the tractive force of switch pole traction track switch, make 4 millimeters at track switch not the safety index of locking guarantee easily;
2, two throw rods are provided with the anti-asynchronous mechanism of moving in the switch machine;
3, easy to adjust, maintenance workload is little;
4, adjustable spring being installed decides power apparatus and has overcome oil cylinder bounce-back and play;
5, connect respectively with two indication rods and represent 1,3 and 2,4 four tip of a root rail states, two indication rods are general when stretching conversion about switch machine;
6, mechanical manual setter is housed in the machine, can realizes mechanical hand operation when hydraulic efficiency pressure system is paralysed, be convenient on-the-spot the adjustment and maintenance, mechanical manual setter has two throw rods holding functions respectively.
(4) description of drawings
