Description

Technical Field

[0001] This utility model relates to the field of railway rescue equipment technology, and in particular to a rescue recovery device. Background Technology

[0002] In railway accident rescue, a common scenario involves train derailment, requiring the train to be lifted and reset. Currently, hydraulic jacking and resetting equipment is widely used in railway accident rescue. Major domestic manufacturers of such equipment include Guangdong Sanshui, Hebei Tonghai, Jilin Xianglong, and Beijing Skyworth. Internationally, the most advanced equipment is from the German company LUKAS Multifunctional Hydraulic Equipment. However, with the rapid development of railways, most current hydraulic jacking and resetting equipment used in railway accident rescue is designed for different structures and weights of locomotives, rolling stock, and empty / loaded vehicles. Existing railway rescue equipment cannot simultaneously meet the rescue needs of different types of locomotives, rolling stock, and rolling stock. To meet the rescue needs of all locomotives, rolling stock, and rolling stock, each rescue train is equipped with multiple types of jacking and resetting equipment. Furthermore, existing equipment has a low success rate in one-time jacking and resetting, resulting in low efficiency and unsatisfactory safety and stability during accident rescues. Especially in the area of ​​high-speed train rescue equipment, the hydraulic repositioning equipment for rescue has failed to keep pace with development needs. To date, neither domestic nor international companies have been able to achieve a one-time repositioning of a derailed train. Various railway bureaus and rescue depots still rely on alternating use of main and auxiliary hydraulic jacks, requiring the wheels to be raised before installing the repositioning equipment. This necessitates using jacking equipment to lift the train body before using repositioning equipment to reset it, resulting in extremely low rescue efficiency.

[0003] Therefore, it is necessary to invent a rescue and recovery device that is convenient for locomotives, motor vehicles, rolling stock, and empty and loaded vehicles, to reduce the cumbersome equipment required for rescue and recovery, and to improve the efficiency and safety of accident rescue. Summary of the Invention

[0004] The purpose of this utility model is to provide a rescue and recovery device to address the above-mentioned problems, thereby solving the technical problem that traditional rescue and recovery equipment for locomotives, EMUs, cars, and empty and loaded cars has poor versatility and requires a lifting device to lift the car body before using a reset device to reset the car body, resulting in low rescue efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rescue and retraction device includes a connector and a pair of retraction units arranged opposite each other. Each retraction unit includes a base, a push rod, and a top support. The push rod is hinged to the base, and the top support is hinged to the extended end of the push rod. The top support is provided with a support recess. The connector connects the two bases and restricts the bases from moving away from each other during use.

[0007] Furthermore, the connector includes a lifting sling and an adjusting chain. The lifting sling has connecting rings at both ends, is folded in half, and the two connecting rings are connected to the same base. The adjusting chain has its two ends connected to another base, and its middle section is connected to the middle section of the lifting sling. The length of the adjusting chain is adjustable.

[0008] Furthermore, a hinge seat is provided on the upper part of the base, and the hinge seat is hinged to the push rod through a first pin.

[0009] Furthermore, the hinge seat and the base are detachably separated, the base is flat, and the hinge seat is installed in the middle of the upper surface of the base.

[0010] Furthermore, the hinge seat is provided with pull ears on both sides, and the pull ears are connected to the connector.

[0011] Furthermore, the telescopic end of the push rod is provided with a hinge joint, which is hinged to the top support via a second pin.

[0012] Furthermore, it also includes a motorized hydraulic pump, and the push rod is a hydraulic push rod, which is connected to the motorized hydraulic pump via a high-pressure oil pipe.

[0013] Furthermore, quick-connect plugs are provided at both ends of the high-pressure oil pipe, and the high-pressure oil pipe is connected to the motorized hydraulic pump and push rod through the quick-connect plugs.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] 1. In use, this utility model places two repositioning units on either side of the vehicle body to be repositioned. A connecting piece passes through the gap under the vehicle body, with both ends connected to the two repositioning units, so that the top support is engaged with the lifting portion on the side of the vehicle body. When lifting is required, two push rods extend, raising the entire vehicle body. When repositioning is required, the push rod on one side extends further; the hinged structure of the push rod causes the vehicle body to shift towards the side with the less extended push rod, achieving repositioning. This utility model, with its two repositioning units simply engaged on either side of the vehicle body, is applicable to vehicles of different widths and top heights, greatly improving its versatility. It solves the technical problem of poor versatility in traditional locomotive, EMU, rolling stock, and empty / loaded vehicle rescue and repositioning equipment, which requires a lifting device to lift the vehicle body before using a repositioning device for repositioning, resulting in low rescue efficiency.

[0016] 2. The connecting components of this utility model include a lifting strap and an adjusting chain. Both the lifting strap and the adjusting chain are flexible, facilitating use in uneven railway environments. Simultaneously, the length of the adjusting chain is adjustable, allowing for adjustment of the distance between the two lifting units, further improving adjustability and enhancing the device's applicability to different train cars. The flat base facilitates a large-area flat structure without excessively increasing weight, ensuring ample contact between the base and the ground and reducing the possibility of base sinking and potential safety accidents.

[0017] 3. This utility model uses a motorized hydraulic pump, which offers good mobility; the hydraulic push rod facilitates high thrust and is suitable for use on heavy-duty vehicles. Quick-connect plugs at both ends of the high-pressure oil pipe allow for rapid connection and use of the device, improving ease of use. Attached Figure Description
