Description

Technical Field

[0001] This invention belongs to the field of railway freight car anti-runaway equipment, specifically relating to a clamp-type static anti-runaway device for vehicles. Background Technology

[0002] Currently, my country uses only one type of anti-rollover actuator for arrival and departure lines used in automated hump yard systems: the internal support type. The internal support type has a drawback: when applying single-sided braking to the vehicle, the braking side pressure cannot exceed the maximum allowable stress of the vehicle's wheel axle. Due to this limitation of side pressure, the internal support type is not suitable for parking lines with steep gradients. Summary of the Invention

[0003] The purpose of this invention is to provide a clamp-type static anti-rollover device for vehicles, which can brake the wheels on both sides simultaneously.

[0004] The technical solution adopted in this invention is a clamp-type static anti-rollover device for vehicles, including a hydraulic control unit. The hydraulic control unit is connected to an electrical system via wires, and the hydraulic control unit is connected to two plunger cylinders via oil pipes.

[0005] It also includes a support unit, with braking mechanisms connected to both sides of the support unit, and the braking mechanisms respectively contacting the ends of the plunger cylinder.

[0006] The invention is further characterized in that,

[0007] The support unit includes a rail bearing, both sides of which are connected to the braking mechanism. A base rail is inserted in the middle of the rail bearing, and a rail pad is provided between the rail bearing and the base rail.

[0008] The braking mechanism includes brake calipers. The two brake calipers are connected to the rail bearings via the main shaft. The two brake calipers are in contact with the ends of the plunger cylinders. Brake rails are connected to the two sides of the two brake calipers that are close to each other.

[0009] Both the rail bearing and the brake caliper have oblong holes at their respective positions, and guide shafts are inserted into the oblong holes.

[0010] A fixing plate is connected to the bottom of the plunger cylinder.

[0011] The beneficial effects of this invention are that when the clamp-type static anti-rollover device brakes the vehicle, the wheel is subjected to a double-sided force with equal torque on both sides, which has no impact on the life of the wheel axle. The output pressure is not limited by the maximum allowable stress of the vehicle wheel axle, which greatly improves the anti-rollover capability of the vehicle. It can be applied to parking lines with large slopes. The device has a simple structure, safe and reliable operation, simple and convenient maintenance and installation, and strong anti-rollover capability. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] The clamp-type static anti-rollover device of the present invention, such as Figure 1 As shown, it includes a hydraulic control unit 11, which is connected to an electrical system 12 via wires, and is connected to two plunger cylinders 1 via oil pipes 10.

[0018] It also includes a support unit, with braking mechanisms connected to both sides of the support unit. The braking mechanisms are in contact with the ends of the plunger cylinders 1. The hydraulic control unit 11 controls the lifting and lowering of the two plunger cylinders 1, thereby enabling the braking mechanism to start and stop, and the braking mechanism applies brakes to the vehicle.

[0019] like Figure 2-3 As shown, the support unit includes a rail support 9, with both sides of the rail support 9 connected to the braking mechanism. A base rail 7 is inserted into the middle of the rail support 9, and a rail pad 6 is provided between the rail support 9 and the base rail 7. The entire braking mechanism floats vertically along the base rail 7.

[0020] The braking mechanism includes brake calipers 2, two of which are connected to rail bearings 9 via a main shaft 4. Each brake caliper 2 contacts the end of a plunger cylinder 1. Brake rails 3 are connected to the two adjacent sides of each brake caliper 2 via connecting bolts. Both brake calipers 2 rotate along the axis of the main shaft 4. The brake rails 3 are composed of a combination of steel rails and composite materials. The composite materials are arranged in sections on the rail surface to increase the static friction between the brake rails and the vehicle wheelsets. When the brake rails 3 brake the wheels, the piston of the plunger cylinder 1 rises, lifting one side of the brake calipers 2. The brake calipers 2 rotate along the main shaft 4, thereby driving the brake rails 3 to brake the wheels.

[0021] Both the rail bearing 9 and the brake caliper 2 have oblong holes 13 at their opposite positions, and guide shafts 5 are inserted into the oblong holes 13. The guide shafts 5 move within the oblong holes 13 to achieve braking, releasing, and positioning of the brake caliper 2.

[0022] A fixing plate 8 is connected to the bottom of the plunger cylinder 1. The fixing plate 8 is arranged between two cement pillows and is close to the cement pillows to prevent displacement.

[0023] The working principle of the clamp-type static anti-rollover device for vehicles of this invention is as follows:

[0024] Braking process: The hydraulic control unit 11 controls the rise of the two plunger cylinders 1. The plunger cylinder 1 generates hydraulic pressure and the cylinder piston extends upward, thereby pushing the brake caliper 2. The brake caliper 2 rotates around the main shaft 4. At this time, the rail support 9 remains stationary. The brake caliper 2 continues to rise. At this time, the guide shaft 5 moves in the waist-shaped hole 13. The guide shaft 5 drives the rail support 9 to rise synchronously (i.e., the entire mechanism rises) until the brake rail 3 presses against the wheel. That is, the two brake rails 3 press against the two sides of the wheel until the designed pressure is reached, thus realizing vehicle braking.

[0025] Release process: The hydraulic control unit 11 controls the descent of the two plunger cylinders 1. The cylinder pistons fall, and the brake caliper 2 and the rail bearing 9 fall together. The descent continues until the release position is reached and then stops.

[0026] This invention relates to a clamp-type static anti-rollover device for vehicles, which uses a double-sided clamping braking method for the vehicle's dual wheelsets. It is fast, simple in structure, and reliable in operation. When braking the vehicle, the wheels are subjected to double-sided forces with equal torque on both sides, which has no impact on the life of the wheel axle. The output pressure is not limited by the maximum allowable stress of the vehicle's wheel axle, thus greatly improving the vehicle's anti-rollover capability.
