Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation electromagnetic boost launch, and in particular to a high-precision fastener for adjusting the lateral and vertical positions of a slide rail. Background Art

[0002] The electromagnetic sled system is a new generation of ultra-high-speed ground dynamic test facilities, which aims to use electromagnetic energy instead of chemical energy for propulsion, and use magnetic levitation technology to eliminate friction resistance and vibration during acceleration, and accelerate the test load to the target speed to realize dynamic environmental testing functions. The traditional electromagnetic booster system adopts a U-shaped structure with integrated suspension propulsion, and its thrust density (thrust-to-weight ratio) is small. At the same time, the electromagnetic sled is also a ground ultra-high-speed test facility that uses the principle of electromagnetic propulsion. By converting electromagnetic energy into the instantaneous kinetic energy required to launch the load, it can accelerate loads from grams to tens of tons to high speed or ultra-high speed within a short distance. At present, high-precision fasteners for adjusting the lateral and vertical positions of slide rails are also used in some high-tech research and development industries or cutting-edge fields of science and technology, such as ultra-high-speed low-vacuum pipeline maglev transportation systems, etc. Regarding the relevant technologies of high-precision fasteners for adjusting the lateral and vertical positions of slide rails, the current representative related patents mainly include the following aspects:

[0003] The patent "A rail fastener and rail fastener system" (CN204959485U) discloses a rail fastener and a rail fastener system for reducing the manufacturing cost of rail fasteners. Technically speaking, the patent is only based on the perspective of cost reduction, and does not consider factors such as adjustment accuracy and adjustment time. Therefore, the solution will greatly increase the labor intensity and working time of workers. At the same time, the strength of the supporting parts is low. Therefore, under the premise of long-term outdoor work, the reliability of the entire system is not high; the patent "A fastener system capable of suppressing rail flipping" (CN206986631U) discloses a rail fastener capable of suppressing rail flipping, which solves the technical problem that the existing rails are easy to flip during use, realizes the reasonable design of the rail fastener, can suppress the rail flipping, and achieves a technical effect of high safety. However, the mechanical structure in this patent is positioned by bolts, which will result in large errors in bolt positioning. At the same time, the overall structure is complex, and workers will spend a lot of time to install it, which will result in large manpower and material costs. The patent "Construction Beam Rail Fastener" (CN201459534U) discloses a construction beam rail fastener that is fixed on both sides of the railway track to ensure the correct position of the rails, which solves technical problems such as the loose connection between the rail fastener and the crossbeam and the unreliable circuit insulation. However, the structure described in the patent lacks flexibility and requires high precision of all technical installation surfaces, otherwise it is difficult to carry out assembly work according to the structure in the figure, which is essentially a lack of elastic size in size. The patent "A Universal Rail Fastener" (CN216663646U) discloses a universal rail fastener to meet the use requirements of various sections of the road, and it is also convenient for the later adjustment and transformation of the sections. However, there are too many structural parts shown in the patent, which affects the stability and reliability of the structure; at the same time, the size of the required parts is relatively high, which inadvertently increases the manufacturing cost of the product. According to the cumulative cost effect, it is estimated that the project will be difficult to land when the actual work is carried out later.

[0004] The slide rail is the basic infrastructure for the operation of the electromagnetic sled and plays a vital role in the performance of the electromagnetic sled, mainly including providing support, guidance and vertical limit for the electromagnetic sled. Therefore, the slide rail structure fastener system must have two special requirements: vertical and horizontal infinite adjustment and large adjustment amount. The adjustment amount of conventional railway fasteners cannot meet the functional requirements, and it is necessary to develop a new fastener system based on the characteristics of the electromagnetic sled project. At present, there are many practical engineering problems in the construction of slide rails in such projects in China, such as poor track fine-tuning ability, difficulty in replacement after damage, difficulty in maintenance, and unsuitability for long and large line construction.

[0010] Based on the structure of the high-precision fasteners for adjusting the lateral and vertical positions of the slide rails, the connecting cavity is an overall rectangular structure, the support blocks are arranged on the left and right sides of the connecting cavity, and a universal ball steel roller is also arranged in the connecting cavity; the universal ball steel roller is arranged in plurality between adjacent support blocks.

[0011] Based on the structure of the high-precision fasteners for adjusting the lateral and vertical positions of the slide rails, the universal ball transfer steel ball rollers are arranged on the center line in the length direction of adjacent support blocks, and the universal ball transfer steel ball rollers are evenly spaced and arranged in 3 numbers on the center line.

The first through hole and the second through hole are both provided in plurality. When the cover plate is fixed to the support block by bolts, the second through hole is at the bottom of the track.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. This solution uses the connecting cavity to initially insert the track into the predetermined position, and then fixes the track by fixing the cover plate on the support block. When the height position of the track needs to be adjusted, the vertical adjustment component is used to change the height position of the entire two-way fine adjustment combination unit, and the height position of the track fixed thereon is changed synchronously. When the horizontal position of the track needs to be adjusted, the horizontal adjustment component is used to change the horizontal position of the track fixed in the connecting cavity, thereby realizing the horizontal position adjustment of the track. This solution can efficiently adjust the track in the vertical and horizontal directions.

[0019] 2. This solution adds a limit copper sleeve during vertical precision adjustment to avoid the generation of a slope in the horizontal direction during the vertical precision adjustment of the rail, which would cause the rail to lose its horizontality.

[0020] 3. This solution uses a screw jack to apply a numerical direction support force in the vertical direction precision adjustment, and the support force is evenly applied to the rail segment to be adjusted through a double-degree-of-freedom sliding unit. Compared with the traditional bolt-type fasteners for adjusting both sides, the high-precision fasteners for adjusting the horizontal and vertical positions of the slide rails not only increase the adjustment accuracy, but also save nearly 50% of the precision adjustment time;

[0021] 4. In this solution, since the whole set of fasteners introduces mechanical assembly components, the accuracy is much higher than that of traditional bolt limiters. Therefore, the accuracy of the rails is much higher than that of traditional bolt fasteners from the very beginning. Therefore, the vertical error and lateral error of the rails that need to be adjusted will be very small, so that the layout points of the fasteners can be appropriately reduced. Compared with traditional bolt fasteners, the number of fastener layout points can be reduced by at least 30%;

[0022] 5. The core components of this solution, such as the dual-freedom sliding unit, are all machined to ensure their own dimensional accuracy and positional accuracy, and are then mechanically assembled. No fine-tuning is required during the assembly process, and direct assembly is sufficient. This greatly reduces the difficulty of assembly and operation for workers, greatly saves construction time, and also improves the reliability of the entire set of fasteners.

[0037] Example 1

[0038] like Figures 1 to 9 As shown, the present invention provides a technical solution:

[0039] High-precision fasteners for adjusting the lateral and vertical positions of the slide rails, which at least include but are not limited to a two-way fine-adjustment assembly unit 1 and a cover plate 2; the two-way fine-adjustment assembly unit 1 is provided with a connecting cavity 11 for accommodating the track 4, and a support block 12 that cooperates and fixes with the cover plate 2; the track 4 is arranged in the connecting cavity 11 and is fixed by the cover plate 2; the two-way fine-adjustment assembly unit 1 is provided with a vertical adjustment component 13 and a lateral adjustment component 14, the vertical adjustment component 13 is arranged at the bottom of the two-way fine-adjustment assembly unit 1 and is connected to the concrete foundation 3; the lateral adjustment component 14 is embedded in the lateral position of the two-way fine-adjustment assembly unit 1, and the end of the lateral adjustment component 14 can be extended and retracted in the connecting cavity 11.

[0040] Based on the above structure, the track 4 is initially inserted into the predetermined position through the connecting cavity 11, and then the cover plate 2 is fixed on the support block 12 to fix the track 4. When the height position of the track 4 needs to be adjusted, the vertical adjustment component 13 is used to change the height position of the entire two-way fine-adjustment combination unit 1, and the height position of the track 4 fixed thereon is changed synchronously. When the horizontal position of the track 4 needs to be adjusted, the horizontal adjustment component is used to change the horizontal position of the track 4 fixed in the connecting cavity 11, thereby realizing the horizontal position adjustment of the track 4. This solution can efficiently adjust the track 4 in the vertical and horizontal directions.

[0041] As an example, the bidirectional fine adjustment assembly unit 1 is also provided with a sliding guide unit 15 and a connecting through hole 16 cooperating with the sliding guide unit 15 , the sliding guide unit 15 is arranged in the connecting through hole 16 , and the sliding guide unit 15 is symmetrically arranged along the center position of the connecting cavity 11 .

[0042] The sliding guide unit 15 includes a guide support cylinder 151, a limit nut 152 and a brass graphite guide sleeve 153; the bottom of the guide support cylinder 151 is fixedly connected to the concrete foundation 3, and the specific connection method can be bolt connection or welding; the brass graphite guide sleeve 153 is embedded in the connecting through hole 16 and is slidably arranged with the guide support cylinder 151, the guide support cylinder 151 passes through the brass graphite guide sleeve 153 and protrudes from the two-way fine adjustment combination single setting, and the top position of the guide support cylinder 151 is provided with an external thread that cooperates with the limit nut 152, and the limit nut 152 is sleeved on the guide support cylinder 151.

[0043] Based on the above structure, after the height adjustment of the railway rail is completed, in the process of adjusting the vertical precision of the railway rail, the brass graphite guide sleeve 153 mainly plays a guiding role to prevent the railway rail from tilting in the lateral direction, thereby ensuring the accuracy of its adjustment; after the bidirectional fine-adjustment assembly unit 1 is lifted by the vertical adjustment component 13, the limit nut 152 locks the upper end position of the bidirectional fine-adjustment assembly unit 1, and through the cooperation of the vertical adjustment component 13, the brass graphite guide sleeve 153 and the limit nut 152, the precise adjustment of the vertical direction of the bidirectional fine-adjustment assembly unit 1 is achieved.

[0044] As an example, the connecting cavity 11 is a rectangular structure as a whole, the support blocks 12 are arranged on the left and right sides of the connecting cavity 11, and a universal ball steel roller 111 is also arranged in the connecting cavity 11; a plurality of universal ball steel rollers 111 are arranged between adjacent support blocks 12.

[0045] Based on the above structure, a universal ball steel roller 111 is installed on the bottom surface of the dual-freedom sliding unit of this solution, thereby changing the friction mode of the railway rail during lateral fine adjustment to rolling friction, greatly reducing friction, and thus saving manpower.

[0046] As an example, the universal ball transfer rollers 111 are arranged on the center line of the adjacent support blocks 12 in the length direction, and three universal ball transfer rollers 111 are evenly spaced on the center line.

[0047] Based on the above structure, by specially setting the position of the universal ball steel ball roller 111, the track 4 can be better supported in the length direction, so that the track 4 can remain flat when sliding.

[0048] As an example, the support block 12 is provided with a plurality of matching holes 121, and the matching holes 121 are provided in a plurality along the length direction of the support block 12. The cover plate 2 is fixed to the matching holes 121 by bolts, and the cover plate 2 can be fixed to the support block 12 more stably by providing a plurality of matching holes 121.

[0049] As an example, a first through hole 21 cooperating with the matching hole 121 is provided on one side wall of the cover plate 2, and a second through hole 22 cooperating with the top screw 23 is provided on the other side wall. The first through hole 21 and the second through hole 22 are both provided in plurality. When the cover plate 2 is bolted to the support block 12, the second through hole 22 is at the bottom of the rail 4.

[0050] Based on the above structure, when the cover plate 2 is bolted to the support block 12, the thimble is screwed into the second through hole 22 to achieve interference fixation with the track 4, so that the cover plate 2 is firmly pressed against the surface of the railway rail, ultimately achieving lateral freedom restriction of the railway rail.

[0051] As an example, a transverse threaded through hole 131, a transverse precision adjustment bolt 132 and a transverse precision adjustment nut 133 are provided in the bidirectional fine-tuning combination unit 1; the transverse threaded through holes 131 are symmetrically arranged on the bidirectional fine-tuning combination unit 1 along the center of the support block 12, and are set to 4 groups in total; the transverse precision adjustment bolt 132 passes through the transverse threaded through hole 131 and extends into the connecting cavity 11, and the transverse precision adjustment nut 133 is sleeved on the end position of the transverse precision adjustment bolt 132.

[0052] Based on the above structure, when the horizontal position of the track 4 needs to be adjusted, the lateral precision adjustment bolts 132 on both sides are screwed in or out to make the lateral precision adjustment bolts 132 contact the track 4. The position of the lateral precision adjustment bolts 132 in the lateral threaded through holes 131 is changed to achieve precise adjustment of the horizontal position of the track 4. A lateral precision adjustment nut 133 is provided at the end of the lateral precision adjustment bolt 132 to increase the contact surface with the end side of the track 4 and avoid damage to the surface of the track 4.

[0053] As an example, the vertical adjustment assembly 13 is a bolt jack, which includes a base 141, a locking nut 142, a lifting and adjusting nut 143, a pressure-bearing boss 144 and a lifting screw 145; a threaded hole matching the lifting screw 145 is provided in the base 141; the lifting screw 145 is sleeved in the threaded hole, the pressure-bearing boss 144 is arranged at the top position of the lifting screw 145, the lifting and adjusting nut 143 is fixedly arranged on the lifting screw 145, and the locking nut 142 is rotatably arranged on the lifting screw 145; the base 141 is connected to the concrete foundation 3.

[0054] Based on the above structure, when the height position of the bidirectional fine-tuning combination unit 1 needs to be adjusted, the lifting screw 145 is rotated in the threaded hole on the base 141 by rotating the lifting adjustment nut 143 to achieve height adjustment. When it is rotated to a predetermined position, the lifting screw 145 is contacted with the base 141 by rotating the locking nut to lock the height position of the lifting screw 145. Specifically, when the vertical accuracy of the railway rail needs to be adjusted, the locking nut 142 of the screw jack needs to be loosened at this time, so that the pressure-bearing lifting screw 145 can move up and down, and then the lifting adjustment nut 143 is rotated to achieve the up and down movement of the pressure-bearing boss 144, thereby achieving the up and down movement of the railway rail.

[0055] As an example, the concrete foundation 3 may include a concrete support platform 31, reserved wire holes 32, and a pre-embedded equipment installation steel plate 33; the pre-embedded equipment installation steel plates 33 are arranged in multiple intervals on the concrete support platform 31, and the reserved wire holes 32 are arranged between adjacent pre-embedded equipment installation steel plates 33.

[0056] Based on the above structure, the role of the concrete support foundation is to provide support for the entire set of fasteners, railway rails, navigation systems, etc. Among them, the concrete support platform 31 is formed by integral casting; before the concrete support platform 31 is cast as a whole, a threading hole 32 needs to be reserved when the steel bars are tied, so as to facilitate the subsequent system electrical and control wiring; when the concrete support platform 31 is cast, the equipment installation steel plate 33 needs to be embedded in advance, so as to facilitate the installation and welding of various mechanical equipment. The screw jack is a shelf product, which can be directly purchased by selecting a specific model according to the actual working conditions. It has been verified by actual use that the product has low cost and high reliability.

[0057] The installation method of this scheme is: first install the screw jack, which can be directly welded to the embedded equipment installation steel plate 33, or connected by bolts; then install the sliding guide unit 15, which is connected to the flange hole of the embedded equipment installation steel plate 33 of the concrete foundation 3 by bolts, and then cool the brass graphite guide sleeve 153 in liquid nitrogen and install it on the double-degree-of-freedom sliding unit, and then install the whole on the sliding guide unit 15, and then install other auxiliary parts, and the installation method is all bolt connection.

[0058] In the present invention, the screw jack and universal ball steel roller 111 used can be purchased directly on the market; the required processed parts are all made of ordinary carbon steel, which has the advantages of low cost, easy processing and transportation, good toughness, etc. The concrete used in the concrete foundation 3 is also a common product on the market, which has the advantages of low cost, sufficient goods and easy to obtain, etc.

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