Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway engineering machinery, and in particular to a work vehicle and system applied to replacement of whole turnout track components. BACKGROUND

[0002] The turnout track component mainly refers to a whole track component composed of components such as a frog, a point rail, a connecting rail and a basic rail above a sleeper, and has the main characteristics of long size and heavy weight, and is difficult to replace manually, and existing equipment cannot meet the requirements. With multiple speed increases of railways, vehicles pass quickly, and wheels impact and crush, which easily leads to long-distance wear of a rail line, especially a turnout, which is more easily worn and needs to be replaced. At the same time, high-frequency passage of vehicles requires that the rail be quickly repaired after wear. In order to save time, the whole turnout track component needs to be replaced at the same time, and because the operation area is limited, the track component is long, large and heavy, and existing rail replacement vehicles and 25-ton rail cranes cannot meet the requirements. Therefore, replacement of the whole turnout track component is a very difficult work, and improvement is urgently needed.

[0003] In the prior art, replacement of turnout components mainly has the following methods:

[0004] The first method is to use 2-3 25T hoisting rail cars from adjacent lines to hoist and operate large track components. However, this scheme is prone to damage due to large deformation of large track components during operation, and because the drivers of multiple hoisting rail cars operate synchronously, large swinging is prone to occur, thereby causing safety hazards and other problems.

[0005] The second method is to use a large turnout large component emergency replacement vehicle set for construction, which is composed of 2 hoisting rail cars and 1-2 rail cars. When the construction operation is performed, the two sets of hoisting rail cars are used to replace the track components. This scheme is limited by the number of lifting points, and usually cannot meet the operation requirements of long and large track components, and the equipment is large, expensive and complex to operate, and the operation preparation time is long, and the operation efficiency is difficult to meet the increasing demand for replacement of turnout track components.

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0064] As shown in the drawings, Figure 1 to the drawings, Figure 26 The specific embodiments of the switch rail replacement operation vehicle and system of the present application are shown, and the present application will be further described below in combination with the drawings and specific embodiments.

[0065] Embodiment 1

[0066] As shown in the drawings, Figure 1 An embodiment of the switch rail replacement operation vehicle of the present application specifically includes:

[0067] Vehicle marshalling;

[0068] The vehicle marshalling includes a first rail car 1, an equipment flat car 2, a rail flat car 4 and a second rail car 3 connected in sequence.

[0069] As shown in the drawings, Figure 2 to the drawings, Figure 6 The first rail car 1 is used to pull the equipment flat car 2 (which can specifically adopt a 15.4m flat car), and the equipment flat car 2 is used to load the gantry crane device 5 and the lifting platform 6.

[0070] The second rail car 3 is used to pull the rail flat car 4, and the rail flat car 4 is used to load the switch rail 20.

[0071] Example 2

[0072] As attached Figure 1 As shown, an embodiment of the turnout rail component replacement system of this application specifically includes:

[0073] The turnout rail component replacement vehicle as described in Example 1;

[0074] The gantry crane 5 and the lifting platform 6 are installed on the equipment flatcar 2;

[0075] And turnout rail component 20, which is installed on rail component flatcar 4 and adopts a segmented structure.

[0076] In a preferred embodiment of this application, the equipment flatcar 2 is equipped with four gantry cranes 5 and two lifting platforms 6. The operating system 10 further includes a power unit and a wireless remote controller mounted on the equipment flatcar 2. (See attached...) Figure 26 As shown, the wireless remote controller further includes a signal transmitter 12 and a signal receiver 13 installed on the gantry crane 5 and the lifting platform 6. Multiple gantry cranes 5 and lifting platforms 6 are all operated synchronously and remotely using the wireless remote controller. This system enables on-line operations; all gantry crane 5 retraction and retrieval, and the lifting of turnout rail components 20, can be controlled by the wireless remote controller. All lifting operations are conducted below the gantry cranes 5, ensuring safety, intelligence, and eliminating the risk of contact with the overhead contact line. Simultaneously, multi-point lifting is configured according to the rail component's center of gravity, preventing permanent deformation of the rail component and meeting the requirements of railway turnout 20 laying technology. Intelligent acceleration / deceleration control between the lifting points of multiple gantry cranes 5 ensures good synchronization, minimizes rail component sway, allows for rapid placement into the track, and results in high operational efficiency.

[0077] When the train sets arrive near the turnout area at the work site, they are disassembled. After removing the third component 23 of the old rail, the gantry crane 5 is deployed to unload the second component 22 of the new rail, retrieve the third component 23 of the old rail, and replace the second component 22 of the new rail. The second component 22 of the old rail is retrieved, and the first component 21 and the third component 23 of the new rail are unloaded, the first component 21 of the new rail is replaced, and the first component 21 of the old rail is retrieved. The gantry crane 5 is retrieved, the third component 23 of the old rail is replaced, and the replacement of the turnout rail component 20 is completed.

[0078] The operating system 10 described in this embodiment can complete the replacement of the entire set of turnout rail components 20 on this line within a single track window. The turnout section situation is as follows: Figure 7 As shown. In order to achieve hoisting, the turnout rail component 20 is cut into 3 large components from the insulating joint 11, namely the first component 21, the second component 22 and the third component 23.

[0079] As attached Figure 8 As shown, the first component 21 further includes a straight base rail 211 and a curved tip rail 212.

[0080] As shown in the accompanying drawings Figure 9 The second assembly 22 further comprises straight point rail 221, curved basic rail 222 and frog 223.

[0081] As shown in the accompanying drawings Figure 10 The third assembly 23 further comprises curved lower leg 231 and guard rail 232.

[0082] The first assembly 21, the second assembly 22 and the third assembly 23 are welded as a whole by gas pressure welding or flash welding in the base before being transported to the work site. The turnout rail piece 20 is welded as a whole by high-reliability gas pressure welding or flash welding in the base in advance, and the whole turnout rail piece 20 is hoisted and replaced on site, which can effectively cancel 8 aluminum heat welding points in the turnout area, save 2 skylights required for turnout replacement, and reduce more than 100 person-times of personnel on the track.

[0083] The turnout assembly 20 has irregular cross section and limited space. The turnout rail piece replacement operation system described in the embodiment can pre-fabricate or weld and assemble the whole turnout rail piece 20 in the base, cancel the process of aluminum heat welding in the turnout area, greatly improve the welding quality and efficiency by welding and replacing the turnout area in the base, not only improve the construction skylight operation efficiency, but also avoid the quality problem caused by short-time rapid welding of the turnout rail piece 20 on site, and improve the turnout construction quality and line operation safety.

[0084] When the vehicle formation reaches near the turnout area, the vehicle formation is uncoupled from behind the equipment flat car 2, the equipment flat car 2 is pulled by the first rail car 1 to place the portal crane device 5, and the second rail car 3 and the rail piece flat car 4 are on standby.

[0085] Before placing the portal crane device 5, the third assembly 23 of the old rail is removed and transferred to between the current line 7 and the adjacent line 8 through the simple portal crane 9, and then the simple portal crane 9 is removed. The first rail car 1 and the equipment flat car 2 enter the turnout area to place the portal crane device 5.

[0086] When the portal crane device 5 is deployed, the equipment flat car 2 is pushed in by the first rail car 1, and then the portal crane device 5 is placed along the current line in sequence by using the lifting platform 6.

[0087] After the portal crane device 5 is placed, the rail piece flat car 4 is pushed into the turnout area by the second rail car 3. After the turnout rail piece 20 is aligned, the second assembly 22 of the new rail is lifted from the rail piece flat car 4 by using the portal crane device 5, and is placed between the current line 7 and the adjacent line 8 and close to the leg of the portal crane device 5, while the third assembly 23 of the old rail is lifted onto the rail piece flat car 4, and the second rail car 3 and the rail piece flat car 4 exit.

[0088] When the second component 22 of the old rail is replaced, the second component 22 of the old rail is lifted by the portal crane 5 and placed between the main line 7 and the adjacent line 8 and close to the straight strand side, and the second component 22 of the new rail is lifted into the slot and fixed by the non-hole clamp.

[0089] When the second component 22 of the old rail is recycled, the second component 22 of the old rail is lifted by the portal crane 5, the second railcar 3 and the rail flatcar 4 are pushed in, after the second component 22 of the old rail is placed on the rail flatcar 4, the first component 21 of the new rail is lifted, transversely moved and unloaded, the third component 23 of the new rail is lifted, transversely moved and placed between the main line 7 and the adjacent line 8 and close to the leg of the portal crane 5, and the second railcar 3 and the rail flatcar 4 are withdrawn.

[0090] When the first component 21 of the new rail is replaced, the first component 21 of the old rail is lifted and placed between the main line 7 and the adjacent line 8 and close to the straight strand side, and the first component 21 of the new rail is lifted into the slot to restore the straight strand traffic.

[0091] When the first component 21 of the new rail is recycled, after the first component 21 of the old rail is lifted by the portal crane 5, the rail flatcar 4 is pushed into the turnout area by the second railcar 3, after the first component 21 of the old rail is placed on the rail flatcar 4, the second railcar 3 and the rail flatcar 4 are withdrawn.

[0092] When the portal crane 5 is recycled, the first railcar 1 pushes the equipment flatcar 2 into the turnout area, and the portal crane 5 is recycled along the main line 7 in reverse order by using the lifting platform 6, the vehicle formation is withdrawn, the third component 23 of the new rail is properly placed into the slot, and the replacement is completed.

[0093] When the portal crane 5 is recycled, after the vehicle formation is withdrawn from the turnout area, the third component 23 of the new rail is transferred from between the main line 7 and the adjacent line 8 to the curved lower strand position by the simple portal crane 9, and the replacement is completed.

[0094] The turnout rail replacement operation system described in embodiment 2 can realize on-site hoisting replacement operation of a complete set of turnout rails, and can overcome the technical problems of large local deformation of turnout rails, large hoisting swing, low operation efficiency, and long time occupation of skylight, and the replacement process of the turnout rails is safe and reliable; the complete operation system can replace a complete set of turnout rails within one skylight time, which greatly improves the operation efficiency compared with the existing technical solution which requires ≥4 skylights. The turnout rail replacement operation system of the present application uses a flat car to transport a complete set of turnout rails, which is well adapted to the loading and unloading operation of a complete set of turnout rails and the replacement of the turnout area environment, and systematically solves the technical problems of transportation, hoisting, and replacement of a complete set of turnout rails. The turnout rail replacement operation system of the present application uses multiple gantry crane devices to replace the turnout rails by wireless remote control, which is safe and reliable, simple in structure, and easy to operate. At the same time, the complete set of turnout rails is divided into straight side and curved side parts for hoisting replacement, which is convenient for rail flat car transportation and handling.
