[0027] Please see Figures 1-3 This utility model provides a railway freight car side beam adjustment device, including: a base 1; a lifting assembly 2 disposed on the base 1; and a strut assembly 3 disposed on the lifting assembly 2, wherein the strut assembly 3 includes a first telescopic end 31 and a second telescopic end 32 capable of moving in opposite directions.

[0028] Understandably, the lifting assembly 2, acting as a vertical adjustment mechanism, drives the strut assembly 3 to move vertically as a whole; the strut assembly 3, acting as a horizontal adjustment mechanism, achieves synchronous lateral extension and retraction from the center of the device to both sides through the opposing movements of its first telescopic end 31 and second telescopic end 32. In application, the device is first moved to the working area inside the vehicle body via the base 1; then, the lifting assembly 2 is operated to align the height of the strut assembly 3 with the side beams on both sides of the vehicle body; finally, the strut assembly 3 is driven to extend its first telescopic end 31 and second telescopic end 32 synchronously in opposite directions until they reliably contact the side beams on both sides of the vehicle body and apply the required supporting force, thereby completing the adjustment and fixing of the side beams on both sides of the vehicle body. This achieves mechanized and integrated operation of the side beam adjustment work, significantly improving the stability and operational efficiency of the adjustment process. Furthermore, after the roof assembly is assembled with the side walls and upper beams on both sides of the vehicle body and the main welding is completed, it is only necessary to drive the strut assembly 3 to retract its first telescopic end 31 and second telescopic end 32 towards each other until it detaches from the side walls and upper beams on both sides of the vehicle body, and then remove the device through the base 1.

[0029] The railway freight car side beam adjustment device of this embodiment achieves vertical height adjustment of the support rod assembly 3 through the lifting component 2 and horizontal width adjustment through synchronous extension and retraction of both ends of the support rod assembly 3. This enables the quick and accurate positioning and support of the side beams on both sides of the car body, replacing the traditional method of welding temporary process supports. It realizes the mechanization of side beam adjustment, effectively improves assembly efficiency and quality, and avoids damage to the car body material.

[0030] In some embodiments, the lifting assembly 2 includes: a lifting drive device and a lifting seat, wherein the fixed end of the lifting drive device is connected to the base 1, and the movable end of the lifting drive device is connected to the lifting seat; and the support rod assembly 3 is connected to the lifting seat. In this embodiment, by controlling the operation of the lifting drive device, the lifting seat is driven to move vertically relative to the base 1; the lifting movement of the lifting seat drives the support rod assembly 3 connected to it to move synchronously until the required working height is reached.

[0031] Optionally, the lifting drive device includes a hydraulic cylinder, the cylinder body of which is connected to the base 1, and the piston rod of which is connected to the lifting seat. By controlling the hydraulic oil circuit, the piston rod extends or retracts relative to the cylinder body, thereby lifting or lowering the lifting seat.

[0032] Optionally, the lifting drive device includes a scissor lift mechanism and a linear actuator. One end of the scissor lift mechanism is hinged to the base 1, and the other end is hinged to the lifting seat. The linear actuator is located between the base 1 and the scissor lift mechanism. By controlling the extension and retraction of the linear actuator, the scissor arms of the scissor lift mechanism are pushed or pulled to change their included angle, thereby raising or lowering the lifting seat. The linear actuator can be a pneumatic cylinder, a hydraulic cylinder, or an electric actuator.

[0033] In some embodiments, the strut assembly 3 includes a bidirectional drive device. A first telescopic end 31 and a second telescopic end 32 are respectively disposed on opposite sides of the bidirectional drive device. The bidirectional drive device is used to drive the first telescopic end 31 and the second telescopic end 32 to move synchronously in opposite directions or synchronously towards each other. In this embodiment, by controlling the operation of the bidirectional drive device, the first telescopic end 31 and the second telescopic end 32 can be directly driven to perform linear movements with the same stroke but opposite directions. When support and positioning are required, the strut assembly 3 drives the first telescopic end 31 and the second telescopic end 32 to move in opposite directions until they abut against the side beam; when retraction is required, it drives the first telescopic end 31 and the second telescopic end 32 to move towards each other and disengage from the side beam.

[0034] Optionally, the bidirectional drive device includes: a first cylinder and a second cylinder, the first telescopic end 31 being the piston rod of the first cylinder, and the second telescopic end 32 being the piston rod of the second cylinder. In application, compressed air is synchronously introduced or discharged into the rod chamber or rodless chamber of the first cylinder and the second cylinder to drive the first telescopic end 31 and the second telescopic end 32 to extend or retract synchronously.

[0035] Optionally, the bidirectional drive device includes a double-rod cylinder, with the first telescopic end 31 and the second telescopic end 32 being the piston rods at both ends of the double-rod cylinder. For details regarding the specific structure of the double-rod cylinder, please refer to patent publication number CN219587893U, which will not be elaborated upon here.

[0036] In some embodiments, the railway freight car side beam adjustment device further includes a controller electrically connected to the lifting assembly 2 and / or the strut assembly 3.

[0037] Furthermore, the controller includes a control panel disposed on the base 1, the control panel being provided with a first operating element for controlling the lifting assembly 2 and a second operating element for controlling the strut assembly 3.

[0038] It is understood that in this embodiment, the control panel integrated into the base 1 serves as the human-machine interface. Its internal circuitry transmits the control signals generated by the first operating element to the drive system of the lifting assembly 2, and the control signals generated by the second operating element to the drive system of the strut assembly 3, thereby controlling the lifting and lowering motion of the lifting assembly 2 and the extension and retraction motion of the strut assembly 3, respectively. Optionally, the first and second operating elements can be buttons or joysticks. In application, the operator observes the relative position of the railway freight car side beam adjustment device with the car body, directly operates the first operating element on the control panel to control the lifting and lowering motion of the lifting assembly 2, and operates the second operating element to control the extension and retraction motion of the strut assembly 3, thereby completing the adjustment of the side beam.

[0039] Furthermore, the controller includes a wireless remote control, which is equipped with a third operating element for controlling the lifting assembly 2 and a fourth operating element for controlling the strut assembly 3.

[0040] Understandably, the operator can issue commands via the third and fourth operating components on the wireless remote control. These commands are transmitted wirelessly to the receiver of the railway freight car side beam adjustment device. After decoding the signals, the receiver drives the lifting assembly 2 and the strut assembly 3 to move, thereby achieving remote control. Optionally, the third and fourth operating components can be buttons or joysticks. In application, the operator can control the lifting assembly 2's lifting movement by operating the third operating component on the wireless remote control from a suitable position, and control the strut assembly 3's extension and retraction movement by operating the fourth operating component, thus completing the adjustment of the side beam, making the operation safer and more convenient.

[0041] In some embodiments, the railway freight car side beam adjustment device further includes an external side wall limiting component for providing a supporting force on the outside of the car body in the opposite direction to the strut assembly 3.

[0042] It should be explained that during use, the base 1, carrying the lifting assembly 2 and the strut assembly 3, is located inside the vehicle body, while the external side wall limiting assembly is located outside the vehicle body. In application, while or before the first telescopic end 31 and the second telescopic end 32 of the strut assembly 3 move in opposite directions to press against the inner wall of the side beam, the external side wall limiting assembly is positioned on the corresponding outer side of the vehicle body and a pressing force is applied. During retraction, the pressing force of the external side wall limiting assembly is first released, and then the internal strut assembly 3 is controlled to retract. Thus, through the synergistic effect of the inner and outer clamping, the overall stability and positioning accuracy during the side beam adjustment process can be significantly enhanced, effectively preventing unilateral deformation or overall displacement of the side beam.

[0043] In some embodiments, the base 1 is provided with wheels 11. Optionally, the wheels 11 are casters.
