The underframe bears the entire weight of the upper vehicle body and the load, and transfers the weight to the running gear through the upper and lower center plates. The underframe of a truck is generally composed of a center beam, side beams, pillow beams, cross beams, end beams and floor beams. The center beam is located in the center of the underframe and is the foundation and main load-bearing member of the entire underframe.

[0003] However, the existing truck center beams are usually transported in the form of transmission rollers, which has the problem that they can only transport open car center beams and flat car center beams, but cannot transport cap-shaped steel center beams and box-shaped beams; therefore, it does not meet the existing needs, and a multi-axis slope plate chain transmission device for truck center beams is proposed.

[0025] At least two fixing plates 102 are provided, and both fixing plates 102 are installed above the base 101. The guide plate 103 is installed above the fixing plate 102, and the side plate 104 is installed on the side of the fixing plate 102. A plurality of long grooves 1031 are provided below the guide plate 103, a blocking bar 1033 is provided above the guide plate 103, a through hole 1032 is provided inside the guide plate 103, and the positioning key 1021 is located inside the long groove 1031.

[0026] The truck center beam is placed on the wing plate 203 between the two guide plates 103. The positioning key 1021 is first clamped in the long groove 1031 at different positions to change the distance between the two guide plates 103. Then, one end of the screw is passed through the through hole 1032 to the inside of the fixed plate 102 to connect the guide plate 103 with the fixed plate 102, thereby meeting the transportation needs of truck center beams of different widths and further improving applicability.

[0027] The plate chain transmission assembly 2 is located between the two fixed plates 102, the two ends of the transmission shaft 201 are connected to the fixed plates 102 through bearings, the two ends of the driven shaft 202 are connected to the fixed plates 102 through bearings, the wing plate 203 is connected to the side of the connecting plate 204 through screws, the connecting plate 204 is connected to the chain 205 axis, the first sprocket 2013 is meshed with the chain 205, the second sprocket 2022 is meshed with the chain 205, a transmission gear 2011 is provided at one end of the transmission shaft 201, the transmission gear 2011 is connected to the motor, at least two driven shafts 202 are provided, and the transmission shaft 201 is located between the two driven shafts 202.

[0028] The truck center beam to be transported is placed on the wing plate 203, and several wing plates 203 support the truck center beam at the same time. Multiple wing plates 203 form a transport platform. When the motor is started, the transmission shaft 201 drives the chain 205 to rotate. When the chain 205 drives the transport platform to start rotating, the truck center beam moves along the rotation direction of the transport platform. The contact surface between a single wing plate 203 and the truck center beam is evenly and stably stressed, so that the plate chain transmission component 2 can be applied to B-shaped steel center beams, hat-shaped steel center beams, H-shaped steel flat car center beams and box beams, etc., further improving the versatility, such as Figure 5-7 shown.

[0029] The contact surface between the transport platform and the truck center beam is an arc-shaped structure, the transport platform above the transmission shaft 201 is the high point, and the transport platform above the driven shaft 202 is the low point.

When the impact seat at the traction end of the truck center beam is transmitted to the climbing stage, the first support roller 2012 and the second support roller 2021 under the wing plate 203 and the chain 205 play a supporting role, thereby reducing the stress deformation of the wing plate 203 and the chain 205 at this stage, and further improving the service life of the device.

[0030] Working principle: After the distance between the two guide plates 103 is adjusted, the truck center beam is placed on the wing plate 203. After the motor is started, the transmission shaft 201 starts to rotate, and the transmission shaft 201 drives the first sprocket 2013 to rotate, and the first sprocket 2013 drives the chain 205 to rotate. The chain 205 simultaneously drives the wing plate 203 and the second sprocket 2022 to rotate, and the second sprocket 2022 drives the driven shaft 202 to rotate, so that the truck center beam can be transmitted along the moving direction of the wing plate 203. The contact surface between the single wing plate 203 and the truck center beam is evenly and stably stressed, so that the transmission operation is smooth and noiseless.
