Anti-derailment train connection device

technical field

The invention relates to transportation tools, in particular to a train connection device for preventing derailment.

Background technique

The connection mode of existing train carriage is the mode of the one-side traction that is connected together by connecting rod and latch. The Chinese patent application number is 931121701, the publication date is March 22, 1995, and the patent document entitled "Railway Bulk Cargo Loading Driving Device" discloses a train connecting device. The connection traction mode of the train also has the mode of bilateral traction.

At present, the trains with double-side traction have the following disadvantages: when the train is moving in a non-straight line (that is, turning), the traction force on the left and right sides of the rear compartment between adjacent compartments will be unbalanced, resulting in a During the process, the car shakes, and when the turning radius is small, the car at the rear is prone to derailment.

Contents of the invention

The present invention provides an anti-derailment train connection device that can automatically adjust the balance of the left and right traction forces, which solves the problem that the existing train connection devices cause severe shaking and even derailment when turning because the left and right traction forces cannot automatically maintain balance. .

The above technical problems are solved by the following technical solutions: a train connection device for preventing derailment, comprising a pair of tie rods distributed along the front and rear directions and a pair of connecting oil cylinders distributed along the left and right directions, and the pair of tie rods only pass through the The pair of connecting cylinders are connected together, and the connecting cylinders include a cylinder body, a piston located in the cylinder body and a connecting rod connected with the piston, and the cylinder body and the connecting rod are respectively connected to the pair of bolster rods. One of the pillow rods is movably connected together, the piston divides the cylinder body into a front oil chamber and a rear oil chamber, the front oil chambers of the pair of connecting cylinders are connected through the front oil pipe, and the pair of connecting cylinders The rear oil chamber is connected through the rear oil pipe. During use, the adjacent two carriages are connected to one of the pair of sleeper rods. The front carriage pulls the rear carriage on both sides through a pair of connecting cylinders. instant distance between sides equal to the instant distance between the right . Suppose the train turns to the right, the distance between the left side and the right side of the front and rear carriages will change, and the amount of change ΔL= , resulting in the contraction of the right connecting cylinder and the elongation of the left connecting cylinder, resulting in an imbalance in the pressure between the front oil chambers and the rear oil chambers of a pair of connecting cylinders, because the front and rear oil chambers in the two connecting cylinders It is connected, so the oil will flow from one to the other, so that the pressure of the front and rear cylinders connected to the two cylinders is rebalanced, so that the traction force on the left and right sides of the front and rear compartments is automatically adjusted to the same level and the stroke is automatically adjusted. Assuming that the train turns to the left, the principle and process are similar to turning to the right, so no specific description is given.

As a preference, a connecting rod, a pair of universal support balls distributed on both sides of the connecting rod and a pair of scraping sleeves are provided on the sleeper rod, and the pair of scraping sleeves are sleeved on the pair of universal support balls in a one-to-one correspondence. onto the support ball.

The outer casing and some partitions that can be corroded by the corrosive liquid in the corrosive liquid storage tank for a set time, the partition divides the outer casing into several floating chambers, and the number of the floating chambers is the same as that of the cavity The number is equal, the partitions are distributed along the up and down direction, the oil storage tank floats on the corrosive liquid in the corrosive liquid storage tank through the buoy, and each of the floating chambers can independently The oil tank floats; every time the corrosive liquid in the corrosive liquid storage tank corrodes one floating chamber and causes the oil storage tank to descend once, the membrane breaking rod can only puncture the sealing film on one cavity. It can regularly and automatically lubricate the joint connecting the oil cylinder and the pillow rod to reduce the wear of the joint and prolong the service life.

Preferably, one of the oil storage tank and the corrosive liquid storage tank is connected with a guide rod extending in the vertical direction, and the other is connected with a guide sleeve sleeved on the guide rod. It can effectively prevent the phenomenon that the oil storage tank shakes in the horizontal direction during the descending process of the oil storage tank, which causes the rupture rod to fail to puncture the sealing membrane. Improved reliability when breaking membranes.

During use, when the corrosive liquid storage tank is vibrated, the corrosive liquid will slosh. The waves generated by the corrosive liquid slosh will cause the regular decay buoy to rise and fall. If the lifting phenomenon is too large, the membrane rupture rod will puncture the seal. The phenomenon that the lubricating oil flows out before the set time is not reached, that is, the malfunction caused by vibration. After the wave suppressing plate is installed, it can effectively reduce the lifting range of the periodic decay buoy caused by vibration, and avoid malfunction caused by vibration.

Preferably, the peripheral surface of the wave suppressing plate abuts against the side wall of the corrosive liquid storage tank.

The present invention has the following advantages: since the force is transmitted through the connecting cylinder during bilateral traction, and the front and rear cylinders of a pair of connecting cylinders are correspondingly connected together, so that the traction force on both sides can be automatically adjusted to the same magnitude during the traction process And the traction length is matched with the turning radius, so that the shaking during the moving forward of the train and the derailment phenomenon during turning can be reduced.
