Abstract
The present invention relates to goat technical field, more particularly to one kind acts locking separate type electrohydraulic switch machine, including master cylinder and locking oil cylinder, the master cylinder and locking oil cylinder are in parallel, the master cylinder acts for control action bar, and the locking oil cylinder acts for control machinery lock.The present invention is simple in construction, and oil pump can not be acted to master cylinder and locking oil cylinder while fuel feeding, master cylinder motion, locking oil cylinder due to the mechanical lock set thereon.Only after master cylinder action in place, locking oil cylinder could continue to move, and realize locking.During whole locking with unblock, it is small compared to suffered side force on mechanical transmission mode mechanical lock, substantially increase the transmission efficiency of complete machine, and the master cylinder and locking oil cylinder controlled respectively accounts for the volume reduction of complete machine, the space availability ratio built in complete machine is improved, makes the work of goat more safe and reliable.
Description
Technical field
The present invention relates to goat technical field, more particularly to a kind of action locking separate type electrohydraulic switch machine.
Background technology
Foundation《Railway switch machine general technical specifications》, goat should accurately realize after being powered up 5 it is dynamic
Work is:Disconnect former expression, unblock, conversion, locking, the new expression of connection.At present now with goat its action with locking set
In a set of mechanism, directly by transmission mechanism control, deposited always in locking mechanism when larger space is taken in casing, and being changed
In larger side force, transmission efficiency is reduced.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide a kind of action electro-hydraulic turn-out track of locking separate type
Machine, securely and reliably, action separate with locking.
The present invention to achieve the above object, using following technical scheme：
One kind action locking separate type electrohydraulic switch machine, it is characterised in that：Including master cylinder and locking oil cylinder, the master cylinder and
Locking oil cylinder is in parallel, and the master cylinder acts for control action bar, and the locking oil cylinder acts for control machinery lock.
Preferably, the both ends of the master cylinder and locking oil cylinder are connected with A oilholes and B oilholes respectively, the A oilholes and B
Oilhole is connected with sundstrand pump respectively, and the sundstrand pump includes two-way pump, overflow valve, check valve, oil filter and fuel tank, the A
Oilhole connects one end of the overflow valve with B oilholes by oil pipe respectively, and the other end of the overflow valve is connected with the fuel tank,
The one end of the both ends of the two-way pump respectively with the oil pipe and the check valve is connected, the other end of the check valve and institute
One end connection of oil filter is stated, the other end of the oil filter is connected with the fuel tank.
The beneficial effects of the invention are as follows:The present invention is simple in construction, and oil pump is main to master cylinder and locking oil cylinder while fuel feeding
Cylinder movement, locking oil cylinder can not be acted due to the mechanical lock set thereon.Only after master cylinder action in place, locking oil cylinder is
It can continue to move, realize locking.During whole locking with unblock, compared to institute on mechanical transmission mode mechanical lock
It is small by side force, the transmission efficiency of complete machine is substantially increased, and the master cylinder and locking oil cylinder controlled respectively accounts for the volume of complete machine
Reduce, improve the space availability ratio built in complete machine, make the work of goat more safe and reliable.
Brief description of the drawings

Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes the embodiment of the present invention in detail.As Figure 1-3, it is a kind of
Locking separate type electrohydraulic switch machine, including master cylinder 1 and locking oil cylinder 2 are acted, the master cylinder and locking oil cylinder are in parallel, described
Master cylinder acts for control action bar 3, and the locking oil cylinder is used for the action of control machinery lock 4.The master cylinder and locking oil
The both ends of cylinder are connected with A oilholes 5 and B oilholes 6 respectively, and the A oilholes and B oilholes are connected with sundstrand pump respectively, the sundstrand pump
Including two-way pump 7, overflow valve 8, check valve 9, oil filter 10 and fuel tank 11, the A oilholes and B oilholes are connected by oil pipe respectively
Connect one end of the overflow valve, the other end of the overflow valve is connected with the fuel tank, the both ends of the two-way pump respectively with institute
One end connection of oil pipe and the check valve is stated, the other end of the check valve is connected with one end of the oil filter, described
The other end of oil filter is connected with the fuel tank.Master cylinder is connected in parallel with locking oil cylinder, and oil pump gives two oil cylinders by A, B oilhole
Fuel feeding, when A oilhole oil-feeds, master cylinder is because the mechanical lock on locking oil cylinder can not move, when locking oil cylinder moves right reality
After now unlocking, the oil cylinder stop motion, master cylinder drives actuating strut to realize conversion to left movement.After master cylinder moves in place,
Locking oil cylinder continues to move, and mechanical lock thereon forms new locking.Conversely, when B oilhole oil-feeds, locking oil cylinder is to left movement
After realizing unlocking motion, master cylinder can just move right.
Oil pump is to master cylinder and locking oil cylinder while fuel feeding, and master cylinder motion, locking oil cylinder is due to the machinery set thereon
Lock can not act.Only after master cylinder action in place, locking oil cylinder could continue to move, and realize locking.In whole locking and solution
It is small compared to suffered side force on mechanical transmission mode mechanical lock during lock, substantially increase the transmission effect of complete machine
Rate, and the master cylinder and locking oil cylinder controlled respectively accounts for the volume reduction of complete machine, improves the space availability ratio built in complete machine, makes
The work of goat is more safe and reliable.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
