Description

Technical Field

[0001] This invention relates to a snow removal device applicable to different track gauges and equipped with lifting function, belonging to the field of rail transit technology. Background Technology

[0002] In cold northern regions, vehicles running on rails face challenges due to snowfall. Snow easily accumulates on the track surface, not only interfering with the normal operation of rail vehicles but also posing serious safety hazards. Current technology often employs a flat-push snow removal structure for rail vehicles. These devices are mostly made of metal, and their flat-push design easily scratches the track surface, increasing the cost of track repair. Furthermore, most of these snow removal devices are only suitable for track surfaces with a fixed gauge and height; changing the track width or height requires purchasing new snow removal equipment, resulting in resource waste. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a snow removal device that can be used for different track gauges and has a lifting function, which is suitable for track beams of different track gauges and different heights, in order to address the deficiencies of the existing technology.

[0004] To solve this technical problem, the present invention provides a snow removal device suitable for different track gauges and equipped with lifting function, including a vehicle connecting flange, a lifting frame, a lifting cylinder, a telescopic fixing frame, an upper cylinder clamp, a lower cylinder clamp, a lateral telescopic cylinder, a telescopic moving frame, a snow removal device one, a snow removal device two, a pin one, and a pin two. The lifting frame and the lifting cylinder are spaced apart at the bottom of the vehicle connecting flange. The telescopic fixing frame is connected to the lower ends of the lifting cylinder and the lifting frame via pin one. The lateral telescopic cylinder is fixed to the bottom of the telescopic fixing frame via the upper cylinder clamp and the lower cylinder clamp. The telescopic moving frame includes a square tube, a column, a flange plate one, and an ear seat. The two telescopic moving frames are respectively fixed to the top of snow removal device one and snow removal device two via flange plate one. Snow removal device one and snow removal device two have the same structure. The hydraulic rods at both ends of the lateral telescopic cylinder are connected to the telescopic moving frame via the ear seats. The two ends of the telescopic fixing frame cooperate with the rectangular tube of the telescopic moving frame. When the lateral telescopic cylinder extends or retracts, the telescopic moving frame can drive snow removal device one and snow removal device two to move laterally along the telescopic fixing frame.

[0005] The telescopic fixing frame includes a rectangular tube one, a rectangular tube two, a crossbeam, and an ear plate. The rectangular tube one and the rectangular tube two have a hollow structure in the middle, and the rectangular tubes can be inserted into the rectangular tube one and the rectangular tube two of the telescopic fixing frame. The crossbeam is set between the rectangular tube one and the rectangular tube two, and the ear plate is set on the crossbeam and is used to connect the lifting frame and the lifting cylinder.

[0006] The uprights are welded to both sides of the flange plate, the square tube is welded to the uprights, and the lugs are welded to the middle of the flange plate. They are connected to the transverse telescopic cylinder by pin 2. Bolt holes are opened on the flange plate and it is fixed to the flange plate on the snow removal device by bolts.

[0007] The snow removal device includes a frame body, a flange plate, a motor, a spring, a spring, a roller brush, a bearing, a motor sprocket, a roller brush sprocket, a tail brush lower clamping plate, a tail brush, a cotter pin, and a tail brush. The roller brush is installed in front of the frame body and is driven to rotate by the rotation of the motor to sweep away the snow on the track beam.

[0008] The main frame is welded together from screw rod one, screw rod two, square tube one, square tube two, front baffle, flat plate, support leg, tail brush upper clamping plate, left side plate, right side plate, stiffening plate and angle steel; the left side plate and right side plate have holes for installing bearings, and the roller brush is assembled on the main frame through the bearings; the stiffening plate and angle steel are used to increase structural stability.

[0009] The plate has drilled holes, and the motor is fixed to the plate with bolts; the upper clamping plate of the tail brush has drilled holes, which cooperate with the holes of the lower clamping plate of the tail brush, and the tail brush is clamped to the snow removal device with bolts. The tail brush has a lateral movement angle, which can sweep the snow off the track.

[0010] The two ends of the central shaft of the roller brush are machined with shoulders, grooves and keyways by a lathe; the roller brush sprocket has the same hole diameter as the roller brush shaft diameter and also has a keyway; the roller brush shaft end and the roller brush sprocket are installed by a key to prevent the roller brush sprocket from rotating; the axial direction is fixed to the retaining ring by the shoulder to prevent axial movement; the two ends of the roller brush are installed on bearings, and the outer shaft of the bearing is fixed by a retaining ring to prevent its axial movement, and then they are installed together on the frame body by bolts.

The motor provides power for the rotation of the roller brush, and the direction of rotation of the roller brush is counterclockwise when viewed from the right side of the driving direction.

[0012] The screw is inserted into spring one, and the screw two is inserted into spring two. Screw one and screw two are installed on flange plate two. Flange plate two is fastened with eight nuts above it. Each screw is equipped with two nuts to prevent the nuts from loosening due to vibration during operation. At the same time, screw one and screw two are drilled with pin holes to insert cotter pins to prevent the nuts from falling off and causing accidents.

[0013] The vehicle connection flange includes a flange plate and lugs. The flange plate has four bolt holes and is fixed to the vehicle by bolts. Three lugs are connected to the flange plate. The middle lug is connected to the lifting cylinder by a pin, and the two side lugs are connected to the lifting frame by pins.

[0014] Beneficial effects: This invention can be adjusted according to the track distance to adapt to different track lengths, and can also be adjusted according to the track height, thus increasing the applicability of the device. If the weather clears and sweeping is not required, the snow removal device can be lifted, reducing wear on the roller brush and tail brush. This invention can be quickly installed with bolts in the direction of vehicle travel, making assembly and disassembly convenient, and allowing for easy handling of sudden severe weather. This invention improves the applicability of snow removal devices and reduces procurement costs for enterprises. Attached Figure Description

If the weather clears and snow removal is no longer needed, the snow removal device can be lifted, reducing wear on the roller brush and tail brush. This invention can be quickly installed with bolts in the direction of vehicle travel, facilitating easy assembly and disassembly and enabling it to handle sudden severe weather. This invention improves the applicability of snow removal devices and reduces procurement costs for businesses.
