Background
According to general technical conditions of railway switch machines, the switch machines can accurately realize 5 actions, namely, switching off original representation, unlocking, switching, locking and switching on new representation after being powered on. At present, the action and locking of the existing switch machine are arranged on a set of mechanism and are directly controlled by a transmission mechanism, so that a large space is occupied in a machine shell, and a large lateral force exists in the locking mechanism all the time during switching, so that the transmission efficiency is reduced.
Disclosure of Invention
The invention aims to overcome the defects of the technology and provide an action locking separation type electrohydraulic switch machine which is safe and reliable and can separate actions from locking.
The invention adopts the following technical scheme to realize the aim:
an action locking separation type electrohydraulic switch machine is characterized in that: the mechanical lock comprises a main oil cylinder and a locking oil cylinder, wherein the main oil cylinder and the locking oil cylinder are connected in parallel, the main oil cylinder is used for controlling the action of an action rod, and the locking oil cylinder is used for controlling the action of a mechanical lock.
Preferably, the two ends of the main oil cylinder and the locking oil cylinder are respectively connected with an A oil hole and a B oil hole, the A oil hole and the B oil hole are respectively connected with a combined pump, the combined pump comprises a bidirectional pump, an overflow valve, a one-way valve, an oil filter and an oil tank, the A oil hole and the B oil hole are respectively connected with one end of the overflow valve through oil pipes, the other end of the overflow valve is connected with the oil tank, the two ends of the bidirectional pump are respectively connected with the oil pipes and one end of the one-way valve, the other end of the one-way valve is connected with one end of the oil filter, and the other end of the oil filter is connected with the oil tank.
The invention has the beneficial effects that the structure is simple, the oil pump supplies oil to the main oil cylinder and the locking oil cylinder simultaneously, the main oil cylinder moves, and the locking oil cylinder cannot act due to a mechanical lock arranged on the locking oil cylinder. The locking cylinder can continue to move only after the action of the main cylinder is in place, so that locking is realized. In the whole locking and unlocking process, compared with the mechanical lock with a mechanical transmission mode, the lateral force applied to the mechanical lock is small, the transmission efficiency of the whole machine is greatly improved, the volume of the main oil cylinder and the locking oil cylinder which are respectively controlled is reduced, the space utilization rate of the whole machine is improved, and the work of the switch machine is safer and more reliable.

Detailed Description
The following detailed description of the invention refers to the accompanying drawings and preferred embodiments. As shown in fig. 1-3, the action locking separation type electrohydraulic switch machine comprises a main oil cylinder 1 and a locking oil cylinder 2, wherein the main oil cylinder and the locking oil cylinder are connected in parallel, the main oil cylinder is used for controlling an action rod 3 to act, and the locking oil cylinder is used for controlling a mechanical lock 4 to act. The two ends of the main oil cylinder and the locking oil cylinder are respectively connected with the A oil hole 5 and the B oil hole 6, the A oil hole and the B oil hole are respectively connected with the combined pump, the combined pump comprises a bidirectional pump 7, an overflow valve 8, a one-way valve 9, an oil filter 10 and an oil tank 11, the A oil hole and the B oil hole are respectively connected with one end of the overflow valve through oil pipes, the other end of the overflow valve is connected with the oil tank, two ends of the bidirectional pump are respectively connected with the oil pipes and one end of the one-way valve, the other end of the one-way valve is connected with one end of the oil filter, and the other end of the oil filter is connected with the oil tank. The main oil cylinder is connected with the locking oil cylinder in parallel, the oil pump supplies oil to the two oil cylinders through the A, B oil hole, when the oil hole A is used for oil feeding, the main oil cylinder cannot move due to a mechanical lock on the locking oil cylinder, when the locking oil cylinder moves rightwards to unlock, the oil cylinder stops moving, and the main oil cylinder drives the action rod to move leftwards to realize conversion. When the main oil cylinder moves in place, the locking oil cylinder continues to move, and the mechanical lock on the locking oil cylinder forms a new locking.
