Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway rescue technology, specifically to a wheelless, skateboard-type, direct-push, lateral-movement lifting and rescue device. Background Technology
[0002] The wheelless sliding plate direct-drive lateral movement retraction and rescue device is a railway traffic accident rescue tool used to re-enter derailed vehicles in the event of a locomotive or rolling stock derailment.
[0003] In railway derailment rerailment operations, traditional rerailing equipment, such as winches and rerailing devices, is typically used. However, these devices often require a large operating space, are complex to operate, and demand a high level of technical skill from rescue personnel. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a wheelless, skateboard-type, direct-drive, lateral-movement lifting and rescue device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] Wheelless, skateboard-mounted, direct-drive, lateral-movement retraction and rescue equipment, including:
[0007] The double-track beam has a guide groove at its top;
[0008] A wheelless skateboard-type traverse trolley is mounted on a double rail beam. The gap between the inner top wall of the traverse trolley and the top of the double rail beam constitutes a friction-reducing structure, and the inner side wall of the traverse trolley and the side wall of the double rail beam form a fall-prevention contact surface.
[0009] Reciprocating structures, including:
[0010] A transverse cylinder fixed in a guide groove has its output end connected to the transverse trolley;
[0011] Lifting cylinders mounted on the load-bearing surface of the transverse trolley;
[0012] The top support component located at the output end of the lifting cylinder has a contact surface adapted to the vehicle chassis.
[0013] The lifting cylinder drives the top support to rise and fall, and the lateral cylinder drives the lateral trolley to move laterally, forming a wheel-rail alignment and track lowering.
[0014] Preferably, the traverse trolley achieves directional movement through the sliding engagement between the inner wall of its n-shaped frame and the double track beam, and the traverse trajectory is restricted within the top bearing plane of the double track beam.
[0015] Preferably, the axis of the lifting cylinder is arranged perpendicularly to the bearing plane of the transverse trolley to form an orthogonal arrangement.
[0016] Preferably, when the lifting cylinder is raised or lowered, its output end extends or retracts in stages.
[0017] Preferably, the top support is selected as a coupler top support or a middle beam top support.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] The wheelless, skateboard-mounted, lateral-moving re-lifting rescue device of this invention can operate in relatively narrow spaces, reducing the labor intensity of rescue personnel, and can achieve automated operation, further improving rescue efficiency. Attached Figure Description

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0025] Example
[0026] like Figures 1-2 As shown, the wheelless, sliding, direct-drive, lateral-movement retraction and rescue device includes:
[0027] The double-track beam 1 has a guide groove at its top and adopts a concave hollow welded structure.
[0028] The wheelless skateboard-type transverse trolley 2 is mounted on the double rail beam 1. The gap between the inner top wall of the transverse trolley 2 and the top of the double rail beam 1 constitutes a friction reduction structure, and the inner side wall of the transverse trolley 2 and the side wall of the double rail beam 1 form a fall-prevention surface contact.
[0029] The reduced friction structure gap forms an air gap or micro gap (non-direct contact), which avoids large-area metal-to-metal contact friction when the traverse trolley 2 slides on the double track beam 1, thereby reducing sliding resistance and improving traverse efficiency.
[0030] During lateral movement, the anti-fall surface contact provides lateral support to prevent the lateral trolley 2 from overturning or derailing due to uneven loading or vibration. The surface contact design ensures that the lateral trolley 2 slides only along the length of the double track beam 1, restricting other degrees of freedom (such as deflection and swaying) and improving lateral movement accuracy. Even when subjected to the weight of the vehicle body or lateral inertial forces, the surface contact structure can still maintain smooth sliding without affecting normal lateral movement.
[0031] The top clearance reduces vertical friction, while the sidewall contact provides lateral stability to prevent falls. The combination of these two features enables low-friction, highly reliable lateral movement.
[0032] With a rotary handle-type mounting base and a specially designed wheelless sliding plate, and using a special oil-free lubrication plate, the traverse trolley 2 will not slide naturally when the superelevation on one side of the double track beam 1 is not less than 20mm.
[0033] like Figure 2 As shown, the reciprocating structure 3 includes:
[0034] The transverse cylinder 31, which is fixed in the guide groove, has its output end connected to the transverse trolley 2;
[0035] Lifting cylinder 32 is installed on the bearing surface of the transverse trolley 2;
[0036] The lifting cylinder 32 is a dual-circuit, fully hydraulically controlled cylinder, equipped with a hydraulic safety lock and an emergency device. Its principle is that if an unexpected situation occurs during lifting and the equipment becomes unusable, the safety lock maintains pressure, preventing secondary accidents. The emergency device is an oil release device. Opening the emergency device releases the hydraulic oil, allowing the lifted load to be lowered safely and smoothly. The cylinder can withstand an ultra-high pressure of 63MPa, and the return oil circuit utilizes deep-hole drilling technology in the cylinder wall, ensuring safety and reliability.
[0037] The top support 33 located at the output end of the lifting cylinder 32 has a contact surface adapted to the vehicle chassis.
[0038] Among them, the lifting cylinder 32 drives the top support 33 to rise and fall, and the transverse cylinder 31 drives the transverse trolley 2 to move laterally, forming the track drop after wheel-rail alignment.
[0039] The traverse trolley 2 achieves directional movement through the sliding engagement between the inner wall of its n-shaped frame and the double track beam 1, and the traverse trajectory is restricted within the top bearing plane of the double track beam 1.
[0040] The axis of the lifting cylinder 32 is arranged perpendicularly to the bearing plane of the transverse trolley 2, forming an orthogonal arrangement.
[0041] During the lifting process, the output end of the lifting cylinder 32 extends or retracts in stages. In the rapid lifting phase, a large flow of oil is supplied to achieve rapid lifting, shortening rescue time. In the millimeter-level fine-tuning phase, a small flow rate is switched for precise control, ensuring that the alignment error between the wheel flange and the rail surface is ≤2mm. Through multi-stage pressure release, the wheels gradually lower themselves onto the rail, preventing impact or secondary derailment due to sudden pressure loss. Through segmented action logic, efficiency, safety, and precision are simultaneously improved.
[0042] The top support component 33 is selected as either a coupler top support or a middle beam top support.
[0043] Tilt car body adjustment and restoration: Assemble the lifting and rescue equipment on site and adjust the rerail beam 1. Adjust the length of the lateral movement cylinder 31 and its piston rod to ensure that the lifting cylinder 32 is aligned with the lifting position. Adjust the lateral movement cylinder 31 so that the lifting cylinder 32 is aligned with the lifting position. Install the center beam support or coupler support. When installing the coupler support, the lifting cylinder 32 needs to be aligned with the coupler position, and the lifting cylinder 32 should be extended so that the coupler support is just embedded in the lower part of the coupler. Lock the coupler with the lock nut. Then, perform the lifting-lateral movement-rail lowering steps in sequence to align the wheel and rail before lowering the rail to complete the lifting and rescue operation.
[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
