[0002] In the field of logistics and transshipment, containers and their tooling are generally long and slender in shape. For stability, the bottom of the tooling is designed to be relatively low. However, the existing design of transshipment railcars is relatively high, resulting in poor passability and unbalanced load distribution. At the same time, if the height of the railcar chassis is to be lowered to meet the passability, it is a great challenge to cram two sets of steering drive units (longitudinal and lateral movement) into the low trolley chassis structure. Therefore, in order to solve these two pain points at the same time, it is necessary to propose a highly integrated railcar structure that meets the above requirements. Utility Model Content

[0027] The utility model provides a longitudinal and transverse moving and lifting electric rail vehicle, which aims to solve the problems of the existing rail vehicle in that the vehicle body is high in height, the trafficability is poor, and the structural design is not compact enough.

The walking end of the longitudinal drive unit 3 is also configured with a lifting unit 4 to contact or detach from the ground. The upper surface of the rail car chassis 1 is also evenly distributed with a plurality of lifting units 5 for lifting goods.

[0029] In one embodiment of the present invention, the rail vehicle chassis 1 is designed with a flat rectangular cross-section. Through this structural design, when the track is converted longitudinally and transversely, the vehicle meets the requirements of an extended vehicle model, can distribute the vehicle body load, and make the longitudinal and transverse functional vehicle body shorter, thereby improving the passability, load distribution balance, and stability.

[0030] In one embodiment of the present invention, the transverse drive unit 2 and the longitudinal drive unit 3 are both embedded in the frame gap space at the corresponding positions of the rail vehicle chassis 1. The embedded installation design can greatly reduce the occupied space, reduce the volume, and make the structure more compact.

[0031] In one embodiment of the present invention, the transverse drive unit 2 includes a group of driving wheel pairs 21 arranged at the rear of the rail vehicle chassis 1 and a group of driven wheel pairs 22 arranged at the front of the rail vehicle chassis 1. The driving wheel pairs 21 and the driven wheel pairs 22 are fixed in position by a bearing seat 23 installed on the upper side of the frame of the rail vehicle chassis 1. A first servo motor 24 is also provided on the transmission shaft of the driving wheel pair 21. The driving end of the first servo motor 24 transmits torque to the transmission shaft through a chain drive.

[0032] In one embodiment of the present invention, the transverse drive unit 2 also includes an auxiliary wheel pair 25 arranged at the head extension position of the rail vehicle chassis 1. The auxiliary wheel pair 25 increases the counterweight and grip of the front of the vehicle body and balances the stability of the front and rear of the vehicle.

[0033] In one embodiment of the present utility model, the longitudinal drive unit 3 includes four groups of lifting units 4 arranged on the left and right sides of the rail vehicle chassis 1, and the free end of each group of the lifting units 4 is fixed with a longitudinal wheel pair 31 that moves longitudinally, and the adjacent longitudinal wheel pairs 31 on any one side are configured with a universal telescopic coupling 32. The corresponding rail vehicle chassis 1 structure of the universal telescopic coupling 32 is provided with a second servo motor 33, and the second servo motor 33 transmits torque to the universal telescopic coupling 32 through a chain drive.

[0034] In one embodiment of the present utility model, the lifting unit 4 includes a group of guide rails 41 and a slide 42, the slide 42 is slidably connected to the guide rail 41, the end face of the slide 42 is fixed with a base 43, the top of the guide rail 41 is provided with a connecting frame 44, the base 43 is fixed with a lifting cylinder 45 body, the connecting frame 44 is connected to the driving end of the lifting cylinder 45, the longitudinal wheel pair 31 is fixed on the base 43 and moves up and down following the stroke of the lifting cylinder 45.

[0035] In one embodiment of the present invention, a flange 6 that rotates with the wheel is fixed to one end face of each set of the longitudinal wheels 31, and flanges 6 are provided on both end faces of the universal telescopic coupling 32, which fix the two and transmit torque through the flanges 6.

[0036] The specific structure and working principle of the utility model are as follows: The chassis of the utility model is designed as a flat long rectangular design. The purpose is to realize the longitudinal and transverse conversion of the track, so that the vehicle meets the requirements of the extended vehicle model, can distribute the vehicle body load, and shorten the vehicle body with longitudinal and transverse functions, thereby improving the passability, load distribution balance, and stability. Based on this flat long rectangular structural design, a transverse drive unit 2 for the lateral movement of the rail vehicle and a longitudinal drive unit 3 for the total longitudinal movement of the rail vehicle are configured. In normal state, the wheel set of the transverse drive unit is lower than the height of the vehicle body by x centimeters, and the longitudinal drive unit has two limit positions, namely an upper limit position and a lower limit position. When in the upper limit position, the wheel set of the longitudinal drive unit is flush with or lower than the above-mentioned distance of x centimeters, ensuring that the transverse drive unit is in contact with the ground and bears the vehicle body load. When in the lower limit position, the wheel set of the longitudinal drive unit is lower than the vehicle body height by a value greater than X. That is, when the wheel set of the longitudinal drive unit is lowered, it will lift the chassis to a certain height, so that it contacts the ground and bears the vehicle body load. Specifically, the longitudinal drive unit is raised or lowered in the vertical direction via the lifting unit 4. The universal telescopic coupling 32 for transmitting torque can be axially extended and contracted during the lifting process to compensate for axial variations during movement, thereby achieving the purpose of both lifting and lowering without affecting the transmission of power. The rail vehicle chassis 1 is also equipped with a lifting unit 5, which includes a lifting plate 51 and a mounting plate 52. The mounting plate 52 is fixed to the chassis. A guide seat 53 is fixed to the center of the mounting plate 52. A guide rod 54 is connected to the guide seat 53. The guide rod 54 is connected to the lifting plate 51 to provide a guide base. Two sets of lifting cylinders 55 are provided on both sides of the end surface of the mounting plate 52. Their drive ends are connected to the lifting plate 51 to provide lifting power. The rail vehicle structure provided by the utility model meets the requirements of vehicle body passability, load distribution balance, and stability with a flat, long rectangular chassis design. It integrates two steering drive assemblies without interfering with each other. The two drive assemblies switch the travel direction by lifting. The structural design occupies less space and has a high degree of integration.
