Description

Technical Field

[0001] The utility model relates to the technical field of high-speed rail track construction, in particular to a double-position self-calibration track base embedded part. Background Art

[0002] High-speed railway, referred to as HSR, refers to a railway system with high design standards and can allow trains to travel safely and at high speeds. Its concept is not limited to tracks, nor does it refer to trains. High-speed railway is a railway system with high design standards and can allow trains to run at high speeds. Its design speed is 200km / h, so the initial speed standard of high-speed railway is 200km / h. Later, with the advancement of technology, trains became faster, and different countries in different eras had different definitions of high-speed railways, and stipulated their own detailed technical standards for high-speed railway levels according to their own conditions. The train speeds and railway types involved were not the same.

[0003] The high-speed rail track in the prior art is usually composed of two parallel rails, which are fixed on sleepers, and there is ballast under the sleepers. It is fastened by rail accessories such as rail supports, fasteners, rail clamps, track splints, spring bars, and railroad spikes. When laying the existing track base, two ends of the base are positioned by two embedded parts, so that it is convenient to install the two subsequent rails. After installing one of the embedded parts, the staff usually needs to use other calibration tools or equipment to determine the position of the other embedded part, so that the two embedded parts are in the same straight line, which is convenient for the accurate installation of the subsequent base. In the process of installing embedded parts, there are many calibration tools involved, and the operation is difficult and cumbersome. There is a lack of standardized and unified simplified methods, which makes the installation of embedded parts unstandardized, and there is a lack of specific and adapted special auxiliary tools for standardized and unified operation.

[0011] Preferably, a rotating part is provided at one end of one of the round rods away from the double-headed screw rod, and the rotating part is threadedly connected to one of the round rods through a second bolt.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, after one of the embedded parts is installed, the cloth strips wrapped around the outer walls of the two sleeves can be pulled out in a straight line, so that the two cloth strips in the unfolded state can calibrate the position of the other embedded part waiting to be installed, ensuring that the two embedded parts are in the same straight line after installation, which is convenient for the subsequent accurate installation of the base. During the installation of the embedded parts, the staff does not need to carry other calibration tools and equipment to proofread the positions of the two embedded parts, which improves the installation efficiency of the embedded parts and the accuracy of the installation position, facilitates the subsequent rapid and accurate installation of the base, and ensures the standardized and uniform layout of the embedded parts during the laying of high-speed railway tracks.

[0015] In the utility model, after the support mechanism and the mounting plate are installed and fixed, the fixing plate is pushed upward to move according to the height of the base to be installed, thereby driving the length of the two second telescopic rods to extend, and the adjusted length of the second telescopic rods is limited and fixed with the help of the corresponding second limiting members; according to the width of the base to be installed, the rotating part is rotated to drive the double-headed screw to rotate, so that the two limiting plates can move in a direction of approaching or moving away from each other, and the distance between the two limiting plates is adjusted so that the distance between the two limiting plates is adapted to the width of the base to be installed, so that the limiting plates can limit and fix bases of different heights and widths, thereby improving the adaptability of the embedded parts for bases of multiple sizes.

The two rotating blocks 12 are rotatably connected to the bottom of the mounting plate 1 by means of a screw 18. After the rotating block 12 is rotated to a specified angle, the position of the rotating block 12 after rotation is threadedly fixed by means of a nut and a screw 18, thereby ensuring the stability of the supporting mechanism.

[0027] As a technical optimization solution in the utility model, the support mechanism includes two first telescopic rods 4, the two first telescopic rods 4 are respectively installed at the bottom ends of the two rotating blocks 12, the outer walls of the two first telescopic rods 4 are installed with first limiters 5 for limiting their own lengths, and the bottom ends of the two first telescopic rods 4 are rotatably installed with rotating plates 6. Through the two length-adjustable first telescopic rods 4, they can be flexibly adjusted according to the use requirements. After placing the two first telescopic rods 4 and the rotating plate 6 inside the opened holes, concrete is poured in the holes, and the first telescopic rods 4 and the rotating plate 6 are cast and fixed to ensure the stability of the upper mounting plate 1.

[0028] As a technical optimization solution in the utility model, threaded holes are provided at the ends of the two rotating plates 6 that are close to each other, and a connecting plate 11 is provided at the bottom of the ends of the two rotating plates 6 that are close to each other, and first bolts 7 that are compatible with the two threaded holes are symmetrically installed inside the connecting plate 11. After the two rotating plates 6 are connected and fixed by means of the connecting plate 11 and the first bolts 7, the telescopic lengths of the two first telescopic rods 4 can be adjusted at the same time by moving the two rotating plates 6 up and down, ensuring that the adjusted lengths of the two first telescopic rods 4 are consistent.

[0029] As a technical optimization solution in the utility model, a slide groove 2 is provided on the top of the mounting plate 1, and two sliders 20 are symmetrically installed inside the slide groove 2. The tops of the two sliders 20 are both installed with second telescopic rods 8, and the outer walls of the two second telescopic rods 8 are both installed with second stoppers 13. The tops of the two second telescopic rods 8 are respectively connected to the stopper plates 9 close thereto. The two sliders 20 move back and forth inside the slide groove 2, driving the two second telescopic rods 8 and the stopper plates 9 to move back and forth together.

[0030] As a technical optimization solution in the utility model, the two limit plates 9 are both equipped with a protrusion at one end close to the fixed plate 10, and the two protrusions are matched with the outer wall of the double-headed screw 17. Through the rotation of the double-headed screw 17, the two protrusions and the two limit plates 9 can be driven to move in the direction of approaching or moving away from each other, so that the second telescopic rod 8 and the slider 20 under the two limit plates 9 can be driven to move together, so as to facilitate the adjustment of the spacing between the two limit plates 9, so that the two limit plates 9 can be suitable for bases of different widths; with the help of two second telescopic rods 8 with adjustable lengths, the height of the two limit plates 9 can be adjusted, so that the two limit plates 9 can be suitable for bases of different heights.

[0031] As a technical optimization solution in the utility model, a rotating part 16 is provided at one end of one of the round rods 24 away from the double-ended screw rod 17, and the rotating part 16 is threadedly connected to one of the round rods 24 through a second bolt 23. With the help of the rotating part 16, the double-ended screw rod 17 can be driven manually and quickly, which is conducive to the double-ended screw rod 17 driving the two limit plates 9 to move back and forth; because the rotating part 16 is threadedly installed by the second bolt 23, the rotating part 16 can be quickly removed from the end of one of the round rods 24.

[0032] As a technical optimization solution in the utility model, the auxiliary calibration mechanism includes a sleeve 14 sleeved on the outer wall of two round rods 24, the outer wall of the two sleeves 14 is wrapped with a cloth strip 15, the inside of the two round rods 24 is provided with a slot 22, and the inside of the two slots 22 is inserted with a plug-in 21 for limiting the sleeve 14. When the two ends of the base are limited and fixed with the help of two embedded parts, after one of the embedded parts is installed, the cloth strip 15 wrapped around the outer wall of the two sleeves 14 can be pulled out to calibrate the position of the other embedded part waiting to be installed, ensuring that the two embedded parts are in the same straight line after installation, which is convenient for the subsequent installation of the base, and does not require the staff to carry other calibration tools and equipment, thereby improving the installation efficiency of the embedded parts and the accuracy of the installation position.

[0033] In the utility model, when installing the embedded parts, holes can be first opened in the designated area of ​​the roadbed where the high-speed railway track needs to be installed. Then, according to the depth of the supporting mechanism that needs to be embedded, the two rotating plates 6 can be connected and fixed by means of the connecting plate 11 and the first bolts 7. By moving the two rotating plates 6 up and down, the telescopic lengths of the two first telescopic rods 4 can be adjusted at the same time to ensure that the adjusted lengths of the two first telescopic rods 4 are consistent. After the adjusted first telescopic rods 4 are limited by the corresponding first limiting members 5, the connecting plates 11 and the first bolts 7 are removed, and the rotating plates 6 are rotated and adjusted according to the use requirements to ensure that the two rotating plates 6 can be stably placed in the pre-opened holes. Finally, concrete is poured in the holes, and the two first telescopic rods 4 and the rotating plates 6 are embedded, so that the mounting plate 1 flush with the ground can maintain good stability, which is convenient for the subsequent limiting and fixing of the base.

[0034] After the support mechanism and the mounting plate 1 are installed and fixed as described above, the fixing plate 10 is pushed upward to move according to the height of the base to be installed, thereby driving the length of the two second telescopic rods 8 to extend, and the adjusted length of the second telescopic rods 8 is limited and fixed by means of the corresponding second limiting members 13; according to the width of the base to be installed, the rotating part 16 is rotated to drive the double-headed screw 17 to rotate, so that the two limiting plates 9 can move in a direction of approaching or moving away from each other, and the distance between the two limiting plates 9 is adjusted so that the distance between the two limiting plates 9 is adapted to the width of the base to be installed, so that the limiting plates 9 can limit and fix bases of different heights and widths, thereby improving the adaptability of the embedded parts for bases of multiple sizes.

[0035] After installing one of the above-mentioned embedded parts, the cloth strips 15 wrapped around the outer walls of the two sleeves 14 can be pulled out in a straight line, so that the two unfolded cloth strips 15 can calibrate the position of the other embedded part waiting to be installed, ensuring that the two embedded parts are in the same straight line after installation, which is convenient for the subsequent accurate installation of the base. During the installation of the embedded parts, the staff does not need to carry other calibration tools and equipment to calibrate the positions of the two embedded parts, which improves the installation efficiency of the embedded parts and the accuracy of the installation position, and facilitates the subsequent quick and accurate installation of the base.

[0036] After the installation of the two embedded parts is completed, the second bolt 23 can be removed so that the rotating part 16 can be disassembled to prevent other personnel from being able to freely drive the double-headed screw 17, which would disrupt the positions of the two limit plates 9 and affect the subsequent base installation. At the same time, the two connectors 21 can be taken out and the two sleeves 14 can be removed from the outer wall of the round rod 24 to facilitate subsequent recycling and improve the practicality of the sleeve 14.

[0037] When the staff transports multiple embedded parts to the designated installation area, in order to avoid the problem that the embedded parts are large in size and occupy a large space, resulting in low efficiency in transporting the multiple embedded parts, the two rotating plates 6 can be rotated 180 degrees before transporting the embedded parts, and then the rotating plates 6 are pushed upward and driven to rotate 180 degrees upward by the rotating block 12, so that the two rotating plates 6 are respectively rotated to the top of the two limit plates 9, such as Figure 3 As shown, after the screw rod 18 is locked with the help of the corresponding nut, the two rotating plates 6 are fixed together by the connecting plate 11 and the two first bolts 7, so that the volume of the entire embedded part can be reduced, and the cloth strips 15 on the outer walls of two of the sleeves 14 can be pulled out and unfolded, and multiple embedded parts with reduced volumes can be fastened and connected together, which is convenient for the staff to transport multiple embedded parts.
