Abstract
Disclosed is an oscillating oil cylinder applied to a point switch. The point switch comprises a motor, a spindle, a transmission mechanism, a locking mechanism and an actuating rod, and is characterized by further comprising an oil pump and the oscillating oil cylinder, the motor, the spindle, the transmission mechanism, the locking mechanism, the actuating rod and the oil pump jointly form a power transmission device and a locking device of the point switch, the motor drives the oil pump to rotate, high-pressure oil pumped out enters the oscillating oil cylinder through an oil pipe bundle, the point switch can be directly hydraulically driven to circumferentially move, the spindle is further driven to rotate, rotation of the spindle is transformed into translation of the actuating rod by the transmission mechanism, power for transforming circumferential movement into linear movement is transmitted by means of simultaneous action of the locking mechanism, and the point switch is unlocked, transformed and locked. Therefore, transmission links of the point switch are decreased, the influence of a speed reducer, a friction coupling and the like on the performance of the point switch is eliminated, the service life of the whole point switch is effectively prolonged, and stability and reliability of the whole point switch are effectively improved.
Description
Technical field
The utility model belongs to oscillating oil cylinder, particularly relates to applicable to the oscillating oil cylinder in the railway switch conversion equipment switch machine.
Background technology
Switch machine is the core and the main body of railway switch converting system, is used to draw track switch and accomplishes conversion and locking process.
For some switch machines, owing to being divided into circular movement, its mechanical drive department transfers straight-line motion to, such as the transmission of gear lock locking mechanism; This switch machine is generally the motorized motions mode, need install frictional clutch additional, in addition; Different according to the switch machine traverse, also need install retarder additional.Because the existence of retarder and frictional clutch, not only transmission link is more, volume is bigger to make switch machine, and the life-span is shorter, and stability is good inadequately.
The utility model content
The utility model technical issues that need to address are: a kind of oscillating oil cylinder that is applied in the switch machine is provided; Utilize hydraulic pressure direct drive mechanism to move in a circle; Accomplish circular movement and transfer straight-line transmission of power to; Reduce the transmission link of switch machine, eliminate mechanisms such as retarder, frictional clutch, effectively improve machine life, stability and reliability the switch machine Effect on Performance.
The technical solution of the utility model is: a kind of oscillating oil cylinder that is applied in the switch machine; Switch machine comprises: motor, main shaft, transmission device, locking mechanism and throw rod, it is characterized in that: further comprising oil pump and oscillating oil cylinder, and described motor, main shaft, transmission device, locking mechanism, throw rod, oil pump are formed the power drive and the locking device of switch machine jointly; Described driven by motor oil pump rotation; The high pressure oil that pumps gets in the oscillating oil cylinder through the oil pipe group, utilizes hydraulic pressure direct drive mechanism to move in a circle, and then drives main axis rotation; Described main shaft is converted into the translation of throw rod through transmission device; Action in the time of in conjunction with locking mechanism is accomplished circular movement and is transferred straight-line transmission of power to, realizes release, conversion and the locking process of switch machine.
The utility model compared with prior art has following advantage: after oscillating oil cylinder is applied to switch machine, can utilize hydraulic pressure direct drive mechanism to move in a circle, accomplish circular movement and transfer straight-line transmission of power to.Adopt the transmission link that can reduce switch machine behind this oscillating oil cylinder, eliminate mechanisms such as retarder, frictional clutch to the switch machine Effect on Performance, it is little effectively to improve machine life, stability and reliability and volume.
Description of drawings
Fig. 1 is a switch machine original design scheme drawing;
Fig. 2 installs the structural representation behind the utility model oscillating oil cylinder for switch machine.
Specific embodiments
Describe the embodiment of the utility model in detail below in conjunction with accompanying drawing.
Switch machine shown in the accompanying drawing 1 is an electric switch machine; Motor 1 drives retarder 2 and frictional clutch 3 rotations, and then drives main shaft 4 rotations, and main shaft 4 is converted into throw rod 7 translations through transmission device 5; Release, conversion and the locking process of switch machine are accomplished in action in the time of in conjunction with locking mechanism 6.Retarder 2 output shafts be connected through frictional clutch 3 with main shaft 4.
After adopting the related oscillating oil cylinder of the utility model; The structural representation of this switch machine is shown in accompanying drawing 2, and motor 1 drives oil pump 8 rotations, and the high pressure oil that pumps gets in the oscillating oil cylinder 9 through the oil pipe group; And then drive main shaft 4 rotations; Main shaft 4 is converted into throw rod 7 translations through transmission device 5, and release, conversion and the locking process of switch machine are accomplished in action in the time of in conjunction with locking mechanism 6.The output shaft of oscillating oil cylinder 9 directly is connected with main shaft 4, like this, has cancelled retarder and the frictional clutch in the original design, and complete machine has reduced transmission link, and is more reliable and more stable.
If separately as hydraulic power unit, a cover dynamo oil pump package drives a plurality of oscillating oil cylinders, also helps multi locomotive traction control with motor 1 and oil pump 8.
