Description

Technical Field

[0001] This utility model relates to the field of track installation technology, and in particular to an adjusting fastener for precise positioning and installation of tracks. Background Technology

[0002] In the fields of high-speed transportation equipment testing, precision scientific research experiments, and new rail transit, high-precision track systems, as the fundamental load-bearing and guiding structure, directly determine the reliability of test data based on their geometric accuracy. However, existing high-precision track systems still face significant technical bottlenecks in geometric parameter adjustment, particularly in addressing settlement deviations during civil construction and insufficient foundation construction precision.

[0003] Traditional track systems generally have a small adjustment range in the vertical and horizontal directions (usually less than ±10mm), while in actual engineering projects, track foundation deviations caused by factors such as civil construction errors and uneven foundation settlement can reach over ±20mm. Existing technologies are limited by insufficient travel of the adjustment mechanism and low structural stiffness redundancy, making it impossible to effectively compensate for such large-scale deviations. This forces high-precision tracks to rely on ultra-high standard civil construction, significantly increasing construction costs and time. Furthermore, existing coarse adjustment methods require repeated disassembly and reassembly of the shim system when dealing with large-scale civil construction deviations, further amplifying accumulated errors and reducing adjustment efficiency.

[0035] Example 1

[0036] like Figures 1-6 As shown, this utility model provides a technical solution:

[0037] An adjusting fastener for precise positioning and installation of a track includes, but is not limited to, a vertical adjusting part 1, a horizontal adjusting part 2, and a supporting cavity 3. At least a portion of the vertical adjusting part 1 and the horizontal adjusting part 2 are embedded in the supporting cavity 3 and form a fixed structure with the supporting cavity 3. The vertical adjusting part 1 is provided with a pressing structure for fixing the track 4 and a support member for supporting the track 4. The support member and the pressing structure can be height adjusted in the vertical adjusting part 1. The horizontal adjusting part 2 is provided with a lateral fastener 21 that abuts against both ends of the track 4 and an adjusting member. The lateral fastener and the adjusting member can be horizontally adjusted in the horizontal adjusting part 2.

[0038] Based on the above structure, the support cavity 3 provides a support structure for the vertical adjustment section 1 and the horizontal adjustment section 2, increasing the overall support strength. In use, the support cavity 3 is embedded in the concrete base 5 and forms an integral part with the concrete base 5, which can reduce the contact area of ​​the concrete base 5, avoid damage to the concrete base 5, and increase the load-bearing capacity of the track 4. At the same time, a pressing structure is set in the vertical adjustment section 1 to fix the track 4 in the vertical direction. The support member can adjust the height position of the track 4 in the vertical adjustment section 1, realizing the adjustment of the height position of the track 4 in the vertical position. Meanwhile, the horizontal adjustment section 2 is provided with a side fastener 21 and an adjusting member, which can make the track 4 abut against the side fastener 21. The horizontal position of the track 4 can be adjusted by changing the horizontal position of the side fastener 21 through the adjusting member. The support cavity 3 connects the vertical adjustment section 1 and the horizontal adjustment section 2 into one unit to form an adjustment unit. Multiple adjustment units can be set in the length direction of the track 4 as needed, which can perform high-precision adjustment of the track 4 in the vertical and horizontal directions.

[0039] As an example, the support cavity 3 may specifically include a vertical connecting cavity 31 and a horizontal connecting cavity 32, the top surfaces of the vertical connecting cavity 31 and the horizontal connecting cavity 32 being connected as one unit; the vertical connecting cavity 31 includes a vertical cavity body 311, a first support plate 312 and a first reinforcing rib 313; the top of the vertical cavity body 311 is provided with an opening, the first support plate 312 is provided at the top position of the vertical cavity body 311, and the first reinforcing rib 313 is provided on the end face of the first support plane near the vertical cavity body 311, and multiple first reinforcing ribs 313 are provided along the end face of the first support plane;

[0040] Based on the above structure, the vertical cavity 311 provides a cavity for accommodating the vertical adjustment part 1. The structure of the vertical adjustment part 1 embedded in the vertical cavity 311 is connected to the vertical cavity 311 as a whole by the concrete 6. The contact surface with the concrete base 5 is increased by the first support plate 312, thereby increasing the load-bearing capacity of the entire vertical connecting cavity 31. Multiple first reinforcing ribs 313 are provided in the vertical connecting cavity 31 to increase the pull-out force of the vertical connecting cavity 31 on the concrete base 5, so that the vertical connecting cavity 31 can be more stably assembled in the concrete base 5.

[0041] As an example, the transverse connecting cavity 32 includes a transverse cavity 321, a second supporting plate 322, and a second reinforcing rib 323; the vertical cavity 311 has an opening at the top, the second supporting plate 322 is located at the top of the vertical cavity 311, and the second reinforcing rib 323 is located on the end face of the second supporting plane near the vertical cavity 311, and multiple second reinforcing ribs 323 are provided along the end face of the second supporting plane; the first supporting plane and the second supporting plane are integrally formed and located on the same horizontal plane.

[0042] Based on the above structure, the transverse cavity 321 provides a cavity for accommodating the transverse adjustment part 2. The structure of the transverse adjustment part 2 embedded in the transverse cavity 321 is connected to the transverse cavity 321 as a whole by the concrete 6. The second support plate 322 increases the contact surface with the concrete base 5, thereby increasing the load-bearing capacity of the entire transverse connecting cavity 32. Multiple second reinforcing ribs 323 are set in the transverse connecting cavity 32 to increase the pull-out force of the transverse connecting cavity 32 on the concrete base 5, so that the transverse connecting cavity 32 can be more stably assembled in the concrete base 5. At the same time, the first support plane and the second support plane are set on the same horizontal plane and integrally formed, so that they can become a whole structure, forming a unit structure for adjusting the transverse and vertical directions of the track 4.

[0043] As an example, the vertical adjustment part 1 may include a vertical adjustment screw 11, a support nut 12, a pillow plate 13, a pressure plate 14, and an adjustment nut 15; the vertical adjustment screws 11 are arranged in pairs in the vertical cavity 311, and an external thread is provided at the upper end of the vertical adjustment screw 11; the support nut 12 is sleeved on the vertical adjustment screw 11; the pillow plate 13 is provided with a connecting through hole that cooperates with the vertical adjustment rod; the pillow plate 13 passes through the two vertical adjustment screws 11 and abuts against the support nut 12;

[0044] The pressure plate 14 is provided with an adjustment hole 16. The pressure plate 14 passes through two vertical adjustment screws 11 and abuts against the sleeper plate 13. One side of the pressure plate 14 is provided with a locking cavity 17 that matches the shape of the bottom of the track 4. When the pressure plate 14 passes through two vertical adjustment screws 11 and abuts against the sleeper plate 13, the locking cavity 17 locks the bottom plate of the track 4 in place. The adjustment nut 15 is provided on the pressure plate 14.

[0045] Based on the above structure, the vertical adjusting screw 11 provides a foundation for supporting the track 4, while the support nut 12 can move along the length of the vertical adjusting screw 11 to adjust the height of the sleeper plate 13, thereby adjusting the height of the track 4. The pressure plate 14 is set to fix the track 4, and the adjusting nut 15 is used to lock it in conjunction with the pressure plate 14. Finally, the locking is completed by the support nut 12 and the adjusting nut 15.

[0046] As an example, the vertical adjusting screw 11 may include a threaded section 111 and a serrated section 112, which are respectively located at the upper and lower ends of the vertical adjusting screw 11.

[0047] Based on the above structure, by setting a serrated section 112 at the bottom of the vertical adjusting screw 11, the bonding strength between the vertical adjusting screw 11 and the concrete 6 in the vertical cavity 311 can be guaranteed.

[0048] As an example, the pressure plate 14 may include a plate body 18, an adjustment hole 16, and a locking cavity 17; the adjustment hole 16 is located at the center of the width direction of the plate body 18, and the adjustment hole 16 is an elongated hole; the locking cavity 17 is located on one side of the plate body, and the locking cavity 17 is an inclined structure adapted to the single-sided track 4.

[0049] Based on the above structure, the position of the pressure plate 14 can be easily adjusted later by setting an elongated hole, and the clamping cavity 17 can be set as an inclined structure to ensure the pressing stability of the track 4.

[0050] As an example, the lateral adjustment part 2 may include a lateral fastener 21, a horizontal adjustment base 22, and a horizontal adjustment screw 23; the lateral fastener 21 is provided with a through hole or through groove that mates with the horizontal adjustment screw 23; the horizontal adjustment base 22 is embedded in the lateral cavity 321 and is connected to the lateral cavity 321 as a whole, and a mating hole for the horizontal adjustment screw 23 is provided at the top position of the horizontal adjustment base 22; the horizontal adjustment screw 23 passes through the mating hole and is connected to the horizontal adjustment base 22 as a whole, and the through hole or through groove of the lateral fastener 21 passes through the horizontal adjustment screw 23 and is fixed by a locking nut;

[0051] Based on the above structure, during installation, the track 4 is placed between the two side fasteners 21. Since the horizontal adjustment base 22 and the horizontal adjustment screw 23 are fixed structures, the position of the side fasteners 21 on the horizontal adjustment screw 23 is adjusted by rotating the locking nut, thereby adjusting the horizontal position of the track 4.

[0052] As an example, the lateral fastener 21 has a U-shaped structure. The lateral fastener 21 specifically includes a first side plate 211, a second side plate 212, and an abutment plate 213. The first side plate 211 and the second side plate 212 are arranged in parallel and perpendicular to the end of the abutment plate 213. The abutment plate 213 is provided with a through hole or a through groove.

[0053] Based on the above structure, by setting the lateral fastener 21 as a U-shaped structure, the contact area between the lateral fastener 21 and the second support plate 322 can be increased, ensuring the stability of the support. At the same time, different perforation patterns can be set on the contact plate 213 to adapt to different application environments.

[0054] As an example, the cross-section of the horizontal adjustment base 22 can be an I-shaped structure. Along the length of the horizontal adjustment base 22, protrusions 221 can also be provided. The protrusions 221 are spaced apart along the length of the horizontal adjustment base and are symmetrically arranged around the center of the horizontal adjustment base 22.

[0055] Based on the above structure, by setting the horizontal adjustment base 22 as an I-shaped structure, the difficulty of obtaining the overall material can be simplified. At the same time, by setting the protrusion 221 in the length direction of the horizontal adjustment base 22, the pull-out force of the horizontal adjustment base 22 embedded in the concrete 6 of the horizontal cavity can be increased, thus ensuring the stability of the support.

[0056] This solution can meet the requirements of high-precision installation; the rails have a large adjustable range in both vertical and horizontal directions, reaching ±20mm or more, which can effectively compensate for settlement changes during civil construction and solve problems such as poor civil construction accuracy.

[0057] This scheme uses two vertical adjusting screws 11 pre-embedded in the positioning plate, the rail sleeper plate 13 as rail support, and the pressure plate 14 to press the rail. The vertical adjustment of the rail is ensured by the up and down movement of the adjusting nut 15 on the vertical adjusting screw 11, and the rail can be locked by the adjusting nut 15.

[0058] Meanwhile, the horizontal adjustment base 22 is pre-embedded and cast into the positioning plate. The horizontal adjustment screw 23 and the lateral fastener 21 on the horizontal adjustment screw 23 are used to adjust the horizontal direction of the rail 4. The rail position can be locked by adjusting the nut 15.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
