Description

Technical Field

[0001] The present invention relates to the field of railway rescue equipment, particularly rescue equipment for EMUs in tunnels. Background Art

[0002] With the increasing development of railway transportation, the EMUs running on the lines are gradually popularized and increased. EMUs run at high speeds and have special structures. Therefore, the derailment rescue of EMUs in railway transportation poses a more severe test. Due to the too low jacking point of EMUs, most EMUs are in an inclined state after derailment, resulting in an even lower jacking point. It is difficult to straighten them without special tools. At the same time, traditional jacking rescue methods require multiple operations to complete the rescue. Crane rescue is restricted by terrain such as bridges and tunnels. At the same time, the power grid must be removed before rescue, greatly increasing the rescue time. Therefore, it is urgent to develop a special rescue equipment suitable for various complex working conditions, especially suitable for quickly and safely rescuing derailed EMUs in tunnels. This set of equipment can ignore the height of the jacking point after the derailment of the EMU, avoid the difficult straightening operation, and can jack and restore the accident vehicle to the track in one lift, and can use this equipment to carry out safe, reliable and rapid rescue operations. Summary of the Invention

[0003] The purpose of the present invention is to provide rescue equipment for EMUs in tunnels to solve the defects and deficiencies existing in the prior art.

[0004] To achieve the above purpose, the following technical solutions are provided:

[0005] The rescue equipment for EMUs in tunnels has a structure including a three-stage oil cylinder I, a three-stage oil cylinder II, a traveling trolley I, a traveling trolley II, a transverse movement device and a connecting rope. The three-stage oil cylinder I is fixedly connected to the traveling trolley I, and the three-stage oil cylinder II is fixedly connected to the traveling trolley II. The transverse movement device includes a transverse movement beam, a transverse movement hydraulic cylinder, two sliding trolleys and a sliding hinge. The transverse movement hydraulic cylinder is fixedly installed on the transverse movement beam. The two sliding trolleys are respectively hinged to both ends of the transverse movement hydraulic cylinder. The sliding hinge is fixedly connected to one end of the transverse movement beam. The sliding hinge is hinged to the top of the three-stage oil cylinder II through an oil cylinder pick-up cap. The other end of the transverse movement beam is hinged to the three-stage oil cylinder I through an oil cylinder pick-up cap. One end of the connecting rope is movably connected to the two sliding trolleys.

[0006] As a preferred solution, the three-stage oil cylinder I and the three-stage oil cylinder II have the same structure, and the traveling trolley I and the traveling trolley II have the same structure.

[0007] As a preferred solution, the four corners of the traveling trolley I and the traveling trolley II are each provided with a horizontally adjustable support leg that can be manually rotated and adjusted.

[0008] As a preferred solution, the sliding hinge can slide a short distance at one end of the transverse movement beam.

[0009] The beneficial effects of the present invention are:

[0010] 1. The present invention is a combined rescue device with a light single-piece mass. Most of it is made of non-ferrous metals, which is convenient for handling and installation.

[0011] 2. The present invention has a large hoisting and restoring stroke. With one-time hoisting and transverse movement operation, it can meet the requirements of restoring and rescuing derailed vehicles within a range of 1.1 meters off the track. In addition, the application scenarios of the present invention are wider and more flexible, including derailment accident sites such as inside tunnels where large rescue equipment cannot operate.

[0012] 3. The present invention can meet the hoisting and restoring rescue of accident vehicles with a relatively large range of inclination degrees, and can carry out the restoring and rescuing operation without first righting the vehicle body, reducing the rescue difficulty, saving rescue time, and having a wider and safer application range.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following is a detailed description of the design solution in conjunction with the drawings.

[0018] As Figure 1 and Figure 2 shown, the tunnel rescue equipment for EMUs includes a first three-stage oil cylinder 1, a second three-stage oil cylinder 2, a first traveling trolley 3, a second traveling trolley 4, a transverse movement device, and a connecting rope 11. The first three-stage oil cylinder 1 is fixedly connected to the first traveling trolley 3, and the second three-stage oil cylinder 2 is fixedly connected to the second traveling trolley 4. The transverse movement device includes a transverse movement beam 6, a transverse movement hydraulic cylinder 7, two sliding trolleys 9, and a sliding hinge 8. The transverse movement hydraulic cylinder 7 is fixedly installed on the transverse movement beam 6. The two sliding trolleys 9 are respectively hinged to both ends of the transverse movement hydraulic cylinder 7. The sliding hinge 8 is fixedly connected to one end of the transverse movement beam 6. The sliding hinge 8 is hinged to the top of the second three-stage oil cylinder 2 through an oil cylinder pick-up cap. The other end of the transverse movement beam 6 is hinged to the first three-stage oil cylinder 1 through an oil cylinder pick-up cap. One end of the connecting rope 11 is movably connected to the two sliding trolleys 9.

[0019] Among them, the third-stage cylinder 1 and the third-stage cylinder 2 have the same structure, and the traveling trolley 1 and the traveling trolley 2 have the same structure.

[0020] Among them, horizontal adjusting legs 10 that can be manually rotated and adjusted are provided at the four corners of the traveling trolley 1 and the traveling trolley 2, so that the bottom planes of the legs of the two traveling trolleys can support on the ground, which is used to adjust the perpendicularity of the third-stage cylinder 1 and the third-stage cylinder 2 to the ground, and ensure the stable traveling of the traveling trolley 1 and the traveling trolley 2 when the equipment is carrying.

[0021] Among them, the sliding hinges 8 can all slide a short distance at one end of the transverse beam 6 to avoid the lateral direction caused by the insufficient degree of freedom of the mechanism due to the asynchronous rise of the third-stage cylinder 1 and the third-stage cylinder 2, resulting in unnecessary inclination of the third-stage cylinder 1 and the third-stage cylinder 2.

[0022] Among them, the third-stage cylinder 1 and the third-stage cylinder 2 are both made of high-strength aviation aluminum alloy, and the connection between the two third-stage cylinders and the two traveling trolleys is a detachable connection.

[0023] Among them, the connection between the third-stage cylinder 1, the third-stage cylinder 2 and the transverse movement device is a detachable connection. The two sliding carriages 9 can slide relative to the transverse beam 6 under the control of the transverse movement hydraulic cylinder 7, and the connection between the two sliding carriages 9 and the coupling rope 11 is a detachable connection.

[0024] Embodiment

[0025] As Figure 3 shown, the traveling trolley 1 and the traveling trolley 2 are respectively arranged on the bottom surfaces on both sides of the front end of the accident vehicle. The third-stage cylinder 1 and the third-stage cylinder 2 are respectively fixedly connected to the traveling trolley 1 and the traveling trolley 2. The transverse beam 6 is respectively hinged to the tops of the third-stage cylinder 1 and the third-stage cylinder 2 through the cylinder pick-up cap 5. Among them, the transverse movement hydraulic cylinder 7, the third-stage cylinder 1 and the third-stage cylinder 2 on the transverse beam 6 are all connected to the external hydraulic power source through pipelines, and the third-stage cylinder 1 and the third-stage cylinder 2 are controlled to slowly rise synchronously until the transverse beam 6 is higher than the top of the accident vehicle; at this time, the traveling trolley 1 and the traveling trolley 2 are controlled to slowly move along both sides of the accident vehicle to both sides of the vehicle bogie. After reaching the designated position, the coupling rope 11 is fixedly connected to the accident vehicle, and the third-stage cylinder 1 and the third-stage cylinder 2 are continuously controlled to drive the transverse movement device to slowly rise, and then the accident vehicle is lifted by the coupling rope 11 until the wheel flange is higher than the rail surface. The transverse movement hydraulic cylinder 7 is controlled to slowly move transversely until the accident vehicle is aligned with the rail, and then the third-stage cylinder 1 and the third-stage cylinder 2 are controlled to slowly descend, and the derailed accident vehicle is restored to the track.

[0026] The first three-stage oil cylinder 1 and the second three-stage oil cylinder 2 cooperate with the transverse hydraulic cylinder 7 for operation, which can meet the requirements of the off-line recovery rescue operation within a range of 1.1 meters. Especially in a tunnel where a crane cannot enter for operation, due to the detachable and on-site assembly features of the present invention, it is convenient to transport it to the accident site (inside the tunnel) to complete the rescue operation. At the same time, due to the use of the lifting and recovery rescue method, regardless of whether the vehicle body is tilted and the severity of the tilt, the present invention can be applied, and there is no need to straighten the vehicle body first before operation, so the applicable range is wider.
