[0002] When a rail vehicle is derailed during driving, it is necessary to rerail the faulty vehicle. The main equipment used is rerailing rescue equipment. For example, Patent 201621187343.4 discloses a railway rescue double-sided hydraulic recovery equipment, including a crossbeam type hydraulic recovery equipment, a large slider and a small slider. The crossbeam type hydraulic recovery equipment is arranged below the derailed vehicle body on the outer side of the rail; the large slider is arranged below the derailed vehicle body on the inner side of the rail, and the small slider is a long strip with a U-shaped cross section. The top of the small slider is provided with a limiting groove along the length direction, and the cross-sectional width of the limiting groove is greater than the thickness of the train wheel rim; the small slider is slidably arranged on the top surface of the large slider, and the limiting groove is stuck at the bottom of the train wheel rim. The existing recovery and rescue equipment also has a rescue method of using two lifting cylinders for lifting. The cylinders are respectively placed at the vehicle-lifting points on both sides of the vehicle body to lift the vehicle, and then the transverse pulley and transverse cylinder are placed to transversely move the vehicle to the track line.

[0003] Most of the above-mentioned existing technologies are only applicable to ordinary railway train rerailing rescue, while light rail lines mostly use the U-shaped groove splicing bridge construction method. Once a vehicle derails, one side of the vehicle will be close to the U-shaped groove, resulting in a narrow space that rescuers cannot enter and rescue tools are difficult to arrange. On the squeezed bridge side, the jacking cylinder cannot be put in at this time, and the vehicle cannot be lifted to complete the subsequent rescue mission. At this time, two heavy-duty truck cranes and multiple rescuers are needed to complete the rescue mission. Therefore, how to carry out rerailing rescue of light rail trains after derailment in the narrow space section of the viaduct is a technical problem that needs to be solved. Utility Model Content

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0030] like Figure 1-4 As shown, the utility model provides a rescue tool for light rail narrow space rescue, including a transverse track 1, a transverse assembly 2, a jacking assembly 3 and a jacking seat 4; the transverse assembly 2 is installed in the transverse track 1, and a movable end is arranged on it, and the transverse assembly 2 is used to drive the movable end thereon to slide along the transverse track 1 to achieve the effect of lateral pushing; the jacking assembly 3 is arranged on the movable end of the transverse assembly 2, and a lifting end is arranged on it, and the jacking assembly 3 is used to drive the lifting end thereon to move up and down to achieve the effect of lifting; the jacking seat 4 is arranged on the lifting end of the jacking assembly 3, and is used to support to the bottom of the car coupler 501, the rescue tool is easy to carry, and can be inserted under the car coupler 501, the jacking seat 4 is lifted by the jacking assembly 3, the coupler 501 is lifted, and then the transverse assembly 2 is cooperated to drive the jacking assembly 3 and the jacking seat 4 to be adjusted along the transverse track 1, so as to move the derailed train back to the track.

[0031] It can be understood that the light rail line mostly adopts the bridge construction method of splicing U-shaped grooves. Once the vehicle derails, one side of the vehicle will be close to the U-shaped groove, creating a narrow space. At this time, there is a certain space below the position of the end coupler 501 corresponding to the carriage body 5, which can be used for inserting this rescue tool. Refer to Figure 3 , with the transverse movement track 1 as the base, supporting close to the ground, and with the cooperation of the transverse movement assembly 2 and the jacking assembly 3, using the jacking seat 4 as the fulcrum, the coupler 501 is jacked up, and the vehicle body can be directly translated horizontally, and then displaced and restored to the track, making the rescue work simpler and greatly improving the controllability.

[0032] In this embodiment, in order to make the transverse movement track 1 have a certain structural strength, the transverse movement track 1 includes a square frame 11 and reinforcing rods 12. The reinforcing rods 12 are arranged inside the square frame 11 to form a Chinese character 'Ri' shape, having a certain structural strength. And the space between the front and rear sides is used as the transverse movement guide of the transverse movement assembly 2, having the functions of guiding and bottom support.

[0033] It can be understood that the transverse movement track 1 can also adopt a structure of two parallel single rails connected by a connecting rod in the middle, so that it has a basic movement guiding function.

[0034] In this embodiment, in order to streamline the structural dimensions, the transverse movement assembly 2 includes a double-rod hydraulic cylinder 21 and a transverse movement seat 22. The two telescopic ends of the double-rod hydraulic cylinder 21 are respectively connected to the left side wall and the right side wall of the square frame 11. The transverse movement seat 22 is detachably arranged outside the double-rod hydraulic cylinder 21 and is slidably connected to the square frame 11. Through the telescopic action of the double-rod hydraulic cylinder 21, since its two ends are fixed, when it expands and contracts, its cylinder body will slide along the rod body, that is, drive the transverse movement seat 22 to slide along the guiding direction of the square frame 11. It can be built inside the square frame 11, avoiding the expansion of the size of the entire rescue tool and meeting the functional requirements of transverse movement drive. In addition, the transverse movement seat 22 is detachably connected to the double-rod hydraulic cylinder 21, which is convenient for disassembling and storing the entire rescue tool, thus facilitating carrying and assembling for use.

[0035] It can be understood that the transverse movement assembly 2 is not limited to the double-rod hydraulic cylinder 21. When the transverse movement driving force meets the requirements, a motor screw pair structure can also be used for driving, or a single-rod hydraulic cylinder can be used for driving, as long as the basic function of horizontal pushing is satisfied.

[0036] It should be noted that the two telescopic rods at both ends of the double-rod hydraulic cylinder 21 are fixed, and the cylinder body of the double-rod hydraulic cylinder 21 corresponds to the movable end on the transverse movement assembly 2.

[0037] In this embodiment, in order to facilitate disassembly, carrying and assembly for use, an insert block 2101 is provided on the outer side of the double-rod hydraulic cylinder 21, a slot 2201 is provided at the bottom of the transverse shift seat 22, and the insert block 2101 is plugged into the slot 2201. By installing the transverse shift seat 22 downward and plugging the insert block 2101 into the slot 2201, the assembly is completed. The assembly is convenient and quick, and the disassembly is convenient for storage and carrying.

[0038] It can be understood that since the lifting seat 4 is lifted upward, the reaction force is downward, which will tighten the connection between the plug block 2101 and the slot 2201, and then when the transverse movement component 2 is driven laterally, the lifting component 3 and the lifting seat 4 can be stably driven laterally.

[0039] Furthermore, in order to facilitate the transportation of the transverse shift seat 22 and the lifting assembly 3 and the lifting seat 4 installed thereon, handle rings 2202 are provided on both sides of the transverse shift seat 22 to facilitate hand-carrying.

[0040] In this embodiment, in order to simplify the height dimension, a mounting groove 2203 is opened on the top of the transverse displacement seat 22, and the jacking assembly 3 is arranged on the mounting groove 2203, so that the height of the jacking assembly 3 and the transverse displacement seat 22 are partially overlapped, thereby avoiding the height dimension of the entire rescue tool being too high.

[0041] Specifically, the lifting assembly 3 includes a lifting hydraulic cylinder 31 , and the lifting hydraulic cylinder 31 is embedded in the installation groove 2203 .

[0042] It should be noted that the telescopic end of the lifting hydraulic cylinder 31 is the lifting end of the lifting assembly 3 .

[0043] Furthermore, in order to integrate the appearance of the jacking assembly 3 and provide a sufficient fitting area with the coupler 501 , the jacking seat 4 is cylindrical in shape, and the outer diameter of the jacking seat 4 is equal to the outer diameter of the jacking hydraulic cylinder 31 .

[0044] Furthermore, in order to prevent slipping during jacking, an anti-skid pad is provided on the top of the jacking seat 4.

[0045] In this embodiment, in order to balance the support force, the transverse displacement seat 22 includes a sliding seat 221 and an extension seat 222. The sliding seat 221 is slidably connected to the inner side of the square frame 11, and the square frame 11 guides the movement of the sliding seat 221. The extension seat 222 is arranged on the top of the sliding seat 221, spans the top of the square frame 11, and is slidably connected to the top of the square frame 11. The extension seat 222 is slidably connected to the top of the square frame 11 to avoid that all the lifting force acts on the double-rod hydraulic cylinder 21, thereby balancing the support force, improving the overall support stability, extending the service life of the double-rod hydraulic cylinder 21, and reducing the probability of failure.

[0046] The specific working process of the utility model: In the rescue of the two end carriages, refer to Figure 3 , place the rescue tool under the coupler 501 at the end of the car body 5, push the lifting seat 4 with the lifting hydraulic cylinder 31 on the lifting assembly 3, support the lifting seat 4 to the bottom of the car coupler 501, and then use the double-rod hydraulic cylinder 21 on the transverse shift assembly 2 to perform a telescopic action, and laterally displace the transverse shift seat 22 to make the lifting seat 4 lift the car body 5 to rerail; in the rerailing rescue of the middle car, by dismantling the vehicle's through-passage 502, the narrow space between the two cars is generated, and the rescue tools and sleepers are sent to the designated position by utilizing the space formed, and then the lifting assembly 3 and the lifting seat 4 are cooperated for jacking, and the transverse shift assembly 2 is cooperated for transverse movement, and then the rerailing is completed to meet the rescue needs in the narrow space.

[0047] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
