Description

Technical Field

[0001] This utility model relates to the technical field of fixed supports for overhead contact lines. More specifically, this utility model relates to an emergency repair support for a titanium alloy base of a railway overhead contact line. Background Technology

[0002] Emergency repair supports are needed when railway overhead contact line support pillars are damaged by natural disasters such as earthquakes. After installation, these supports allow trains to pass through the area at low speeds during the repair period, preventing train stoppages due to unforeseen circumstances. Currently, most railway-specific emergency repair supports are inconvenient to transport and install, and their frame-type towers are prone to tilting during installation, making them unsuitable for the high verticality requirements of superelevation railways. Therefore, there is an urgent need for a titanium alloy emergency repair support that is easy to transport and install while also being able to handle superelevation conditions on railways.

[0003] Utility model patent CN202578103U discloses a multi-functional railway emergency repair support, including a high-strength aluminum alloy support body, a steel base, base legs for leveling the steel base, and support accessories. It adopts a modular connection, which is simple in structure, easy to use and stable, detachable, and convenient to assemble, transport, and install. However, the base legs of this device are relatively slow to adjust the lifting and lowering, and its adjustment of the verticality of the support body is relatively rough, making it difficult to ensure the verticality of the installed support body. Therefore, it cannot meet the verticality requirements of emergency repair supports under railway superelevation conditions. In addition, its base is made of ordinary steel, which is still relatively heavy, making it inconvenient to transport and install. Furthermore, its corrosion resistance is generally poor, and it is prone to rusting during operation, affecting the stability of the device. Utility Model Content

[0012] A set of adjustable bolts and nuts are installed at each corner of the frame-type adjustment frame to adjust the levelness of the frame-type adjustment frame.

[0013] Preferably, each coarse adjustment component includes: an upper support leg connected to the crossbeam and a lower support leg sleeved on the upper support leg;

[0014] The upper support leg has multiple through-hole pin holes along its extension direction.

[0015] The lower support leg is provided with at least one through-hole II that is adapted to the position of the pin hole I;

[0036] Example 1

[0037] A type of emergency repair support for railway overhead contact lines with a titanium alloy base, the structure of which is as follows: Figure 1-6 As shown, it includes: a frame tower 500 for temporary fixation of railway catenary, one end of which is connected to the rail via a rail clamp 200, and the other end of which is in contact with the mounting surface via a frame support frame 400. The frame tower 500 is mounted on the base 100 via a fine adjustment component 300.

[0038] The frame support 400 includes a crossbeam 401 that is detachably connected to the base 100;

[0039] Two sets of coarse adjustment components are set at both ends of the crossbeam 401 and their height is adjusted;

[0040] The base 100 is configured as a frame-type titanium alloy base 100.

[0041] In practical applications, the base 100 is made of titanium alloy and consists of two I-beam brackets 107 connected by a connecting plate in the middle. The connection method includes, but is not limited to, welding and bolt tightening. The middle plate of the I-beam brackets 107 is provided with a weight-reducing hole I108. The frame-type titanium alloy base 100 can further reduce its own weight while ensuring its strength, and it is not easy to rust due to humid environment. The base 100 is provided with hinge holes I101 for installing the frame-type tower body 500, hinge holes II102 for installing the fine adjustment component 300, hinge holes III103 for installing the weight bracket, hinge holes IV104 for installing the live bolt 301, and bolt holes I105 for installing the frame-type tower body 500. The base 100 is also provided with a handle 109 for easy handling, and the base 100 is provided with bolt holes II106 for installing the handle 109. The handle 109 can be fixed to the base 100 by bolts or welding.

[0042] The frame-type tower body 500 includes: an upper tower body 501 for fixing the contact wire, a lower tower body 502 disposed below the upper tower body 501 and detachably connected thereto, and an installation frame 503 disposed at the bottom of the lower tower body 502 and having a hinge hole VI 504 for connecting with the base 100 or the fine adjustment assembly 300.

[0043] The frame tower 500 is made of aluminum. When there is no superelevation on the rail, the frame tower 500 can be directly installed on the base 100. When there is superelevation on the rail, the fine adjustment component 300 must first be installed on the base 100, and then the frame tower 500 is installed on the fine adjustment component 300 to ensure that the verticality of the frame tower 500 can be finely adjusted to meet the verticality requirements of the emergency repair support under railway superelevation conditions.

[0044] The base 100 is equipped with two rail clamps 200. The two rail clamps 200 are respectively installed on the I-shaped cross-sections of the two I-shaped brackets 107 of the base 100, and the two rail clamps 200 are located on the same side of the base 100. The rail clamp 200 includes: a tightening screw 201, a dovetail slider 202, a through hole clamp 203, and a pressure plate 204. The rail clamp 200 adopts a dovetail groove 205. The dovetail slider 202 of the rail clamp 200 is made of titanium alloy. The through-hole clip 203 can slide on the dovetail groove 205 structure of the dovetail slider 202. One of the pressure plates 204 is installed on the through-hole clip 203 through a pin hole, and the other pressure plate 204 is installed on the dovetail slider 202 through a pin hole. When the rail clamp 200 is working, the tightening screw 201 tightens the through-hole clip 203 to clamp the lower end of the rail. At the same time, the pressure plates 204 installed on the dovetail slider 202 and the through-hole clip 203 tighten the rail waist to complete the fixation. The structure and working method of this rail clamp 200 are similar to the rail clamping device components of the invention patent with publication number CN 116289358 A: A rail quick clamping device applied to railway track bed. The rail clamp 200 is connected to one end of the base 100 by welding.

[0045] Working principle: By setting up coarse adjustment components and fine adjustment components 300, the verticality of the frame tower 500 is coarsely and finely adjusted in sequence, respectively. The adjustment efficiency is high and the adjustment accuracy is high, which can ensure the high verticality of the installed frame tower 500 to meet the verticality requirements of the emergency repair support under the superelevation conditions of railways. The frame-type titanium alloy base 100 is set up, which is lighter while ensuring its strength, making it easy to transport and install. It also has strong corrosion resistance and is not easy to rust due to the humid environment during operation, which can effectively improve the stability of the device.

[0046] Example 2

[0047] This second embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 2 As shown, based on embodiment 1, it discloses the following improvement: the fine-tuning component 300 includes:

[0048] A frame-type adjustment frame, with a connecting part with a connection hole extending downward from the middle of the adjustment frame;

[0049] A long screw 302, which is mounted on the base 100, is used to rotate the frame-type adjustment bracket through the connection hole;

[0050] The set consists of live bolts 301 and nuts installed at each corner of the frame-type adjustment frame to adjust the levelness of the frame-type adjustment frame.

[0051] In practical applications, the fine-adjustment component 300 is provided with a weight-reducing hole III and multiple hinge holes V303 and bolt holes III305 for mounting the frame-type tower body 500; the lower end of the live bolt 301 has a pin hole, and its lower end passes through the through hole reserved at the fit point of the base 100 and the hinge hole IV104, so that the hinge hole IV104 is aligned with the through hole and the pin 304 is inserted between them to complete the connection between the live bolt 301 and the base 100; the fine-adjustment component 300 is provided with a strip hole through which the live bolt 301 passes, and nuts connected to the live bolt 301 are provided on its upper and lower sides to fix the position. During operation, the levelness of the upper surface of the fine-adjustment component 300 is adjusted by rotating the nuts.

[0052] Working principle: The fine adjustment component 300 is made of titanium alloy and has a weight reduction hole III, a hinge hole V303 for mounting the frame tower body 500, and a bolt hole III305. The fine adjustment component 300 has a strip hole. The fine adjustment component 300 can be adjusted to a horizontal position by using the union bolt 301 and nut installed on the titanium alloy base 100, so that the frame tower body 500 mounted on it remains perpendicular to the horizontal plane.

[0053] Example 3

[0054] This third embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 3 , Figure 7 As shown, based on embodiment 1, the following improvements are disclosed: each coarse adjustment component includes: an upper support leg 404 connected to the crossbeam 401 and a lower support leg 405 sleeved on the upper support leg 404.

[0055] The upper support leg 404 is provided with multiple through-hole pins 411 along its extension direction.

[0056] The lower support leg 405 is provided with at least one through-hole 411 hole II that is adapted to the position of the pin 411 hole I;

[0057] The lower support leg 405 and the upper support leg 404 are fixedly connected by pins 411 passing through pin holes I and II.

[0058] The lower support leg 405 is provided with a base plate 407 that contacts the mounting surface at its lower end;

[0059] The lower support leg 405 is connected to the base plate 407 via a spherical bearing 406.

[0060] The lower sides of both ends of the crossbeam 401 are provided with circular grooves into which the upper support legs 404 can partially extend, and the bottom of the circular grooves is provided with threaded holes that pass through them.

[0061] The diameter of the screw hole is smaller than that of the circular groove, and an adjusting bolt 402 adapted to the diameter of the screw hole is provided inside the screw hole.

[0062] In practical applications, the weight support 600 is mounted on the base 100, and the crossbeam 401 is mounted on the crossbeam 401 of the base 100. The crossbeam 401 has a weight-reducing hole II 410, a cable 700 mounting hole 408, and bolt holes IV 409 for connection to the base plate 407. A pin 403 can be inserted above the adjusting bolt 402 to facilitate rotation of the adjusting bolt 402 and fine-tuning of the height on both sides of the crossbeam 401. The lower support leg 405 has a threaded section at its lower end, and the spherical bearing 406 is connected to the lower support leg 405 via the threaded section. The cable 700 is used to connect the weight support 600 and both sides of the crossbeam 401 to the upper end of the frame tower body 500 respectively; the weight support 600 is used to install the weight 800, and the weight of the weight 800 is transmitted to the upper end of the frame tower body 500 through the cable 700. The weight of the load-bearing cable and contact line connected to the upper end of the frame tower body 500 is partially offset, thereby improving the stress on the frame tower body 500 and reducing the deformation and displacement of the frame tower body 500.

[0063] Working Principle: During operation, first adjust the position of the upper support leg 404 within the lower support leg 405 of each coarse adjustment component, and align the pin 411 through pin 411 hole I and pin 411 hole II to complete the initial height adjustment and fixation. The lower end of the adjusting bolt 402 is tightly against the top of the upper support leg 404. Rotating the pin bar 403 causes the adjusting bolt 402 to rotate, simultaneously raising or lowering both ends of the crossbeam 401 to further adjust its height. The lower support leg 405 is connected to the base plate 407 via a spherical bearing 406, allowing the base plate 407 to rotate freely within a certain angle range. This allows the base plate 407 to flexibly adjust its angle according to different working requirements and terrain conditions, better adapting to complex ground environments. This ensures that the coarse adjustment components can be stably supported and maintain a vertical posture even on uneven ground.

[0064] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.
