Technical Field
[0001] This application relates to the technical field of railway construction, and particularly to a positioning device for high-speed railway catenary. Background Art
[0002] With the rapid development of high-speed railways, the requirements for the stability and reliability of the catenary system are getting higher and higher. The catenary system is an important part of the electrification of high-speed railways, and its function is to provide continuous and stable power supply for running trains. The precision requirements for the foundation embedded anchor bolts of high-speed railway catenary are high, and it is easy to occur deviation and shaking during the construction process, resulting in the deviation of the foundation anchor bolts and the non-compliance of the spacing, which is difficult to handle.
[0003] In the prior art, two sets of devices are required to realize the vertical adjustment and horizontal adjustment processes of the positioning device, and the adjustment needs to be carried out separately, and the adjustment process is also more cumbersome.
[0004] Therefore, it is necessary to develop a new tool for positioning the positioning device of high-speed railway catenary to simplify the positioning adjustment process, improve the positioning accuracy, and ensure the stable operation of high-speed railway catenary. Utility Model Content
[0005] Aiming at the deficiencies of the prior art, a positioning device for high-speed railway catenary is proposed. The purpose of this application is to optimize the structure of the adjustment device of the positioning device to solve the problems of complex structure of the adjustment device and cumbersome use process existing in the prior art.
[0006] The above object of this application is achieved through the following technical solutions: A positioning device for high-speed railway catenary, including a template and a rectangular channel steel frame. Two positioning steel plates are respectively arranged at the upper and lower ends of the rectangular channel steel frame. The positioning steel plates are circular rings. A plurality of anchor bolt positioning holes are opened on both the rectangular channel steel frame and the positioning steel plates. After a plurality of the anchor bolts pass through the anchor bolt positioning holes of the rectangular channel steel frame and the positioning steel plates in sequence, their positions are fixed. An adjustment device is arranged on the outer side wall of the template.
[0007] By adopting the above technical solutions, by integrating the adjustment device on the outer side wall of the template, the adjustment process becomes more concentrated and convenient. The operator does not need to operate the adjustment devices in multiple directions separately. Only by operating a single adjustment device, the overall adjustment of the positioning device can be realized, which greatly simplifies the adjustment steps and improves the work efficiency. After the anchor bolts pass through the anchor bolt positioning holes of the rectangular channel steel frame and the positioning steel plates in sequence and their positions are fixed, this design enables the entire device to be firmly fixed in the predetermined position and is not easy to displace.
[0008] Further, the adjusting device includes support plates on both sides of the template and double-nut adjusting bolts. The cross-section of the support plate in the vertical direction is in a "C" shape, and the opening of the support plate is arranged away from the template. One end of the double-nut adjusting bolt fixes the template, and the other end is inserted into the support plate. Through holes are opened on the upper and lower end faces of the support plate. The adjusting device further includes an adjusting plate, and the upper end of the adjusting plate is fixedly connected to the rectangular channel steel frame, and the adjusting plate is inserted into the through hole.
[0009] By adopting the above technical solution, through the combination of the support plate, the double-nut adjusting bolt and the adjusting plate, the positioning adjustment of the adjusting device in the direction of approaching and departing from one side of the template is realized. The design of the double-nut adjusting bolt makes the adjustment process fast and accurate. By rotating the nut, the distance between the support plate and the template can be quickly adjusted, and then the fine adjustment of the position of the anchor bolt can be realized.
[0010] Further, the adjusting device further includes a scissor mechanism. A chute is arranged on the adjusting plate in the vertical direction. One side of the upper end of the scissor mechanism is hinged to the adjusting plate and the lower end is slidably connected to the chute.
[0011] By adopting the above technical solution, by controlling the telescopic length of the scissor mechanism in the horizontal direction and the orientation in the vertical direction, the horizontal and vertical orientations of the adjusting plate can be changed, so as to realize the positioning adjustment of the anchor bolt.
[0012] Further, the adjusting device further includes a threaded rod. The threaded rod is arranged in the vertical direction. A first slider and a second slider are sleeved on the threaded rod. Both ends of one side of the scissor mechanism are respectively hinged to the first slider and the second slider.
[0013] By adopting the above technical solution, by rotating the threaded rod, the orientations of the first slider and the second slider in the vertical direction can be adjusted, thus simplifying the adjustment of the orientation of the scissor mechanism and improving the convenience of the positioning adjustment operation.
[0014] Further, a clutch device is arranged in the first slider. The clutch device includes a threaded sleeve. The threaded sleeve is threadedly connected to the threaded rod. The first slider is sleeved on the threaded sleeve. A plurality of positioning grooves in the vertical direction are opened on the outer wall of the threaded sleeve. A driving block is slidably connected in the first slider. The driving block is outside the threaded sleeve. A limiting rod is fixed on the side of the driving block away from the threaded sleeve. The limiting rod is slidably connected to the first slider. A through hole is opened in the first slider in the vertical direction. An unlocking plate is slidably connected in the through hole. An inclined unlocking groove is opened on the unlocking plate. A protrusion is fixed on the side of the driving block close to the unlocking plate. The protrusion is slidably connected to the unlocking groove.
[0015] By adopting the above technical solution, by providing a clutch device, the two sliders can not only move equidistantly and in the same direction in the vertical direction, but also fix the first slider to realize the independent up or down movement of the second slider, enabling the two sliders to move relatively, thereby realizing the movement adjustment of the scissor mechanism in both the vertical and horizontal directions on the same device, simplifying the structure of the positioning adjustment device and the process of positioning operation.
[0016] Furthermore, the clutch device further includes a compression spring, and the compression spring is sleeved around the limiting rod.
[0017] By adopting the above technical solution, when the clutch device needs to be unlocked, move the unlocking plate, the protrusion of the driving block slides in the unlocking groove, driving the driving block to move towards the threaded sleeve. At the same time, the driving block is squeezed into the positioning groove on the threaded sleeve under the action of the compression spring, playing a dual insurance role, and also accelerating the sliding and clamping process of the driving block and the positioning groove, improving the fluency and stability of using the positioning device.
[0018] Furthermore, the threaded rod is fixedly connected with a knob.
[0019] By adopting the above technical solution, the knob has relatively delicate adjustment scales, enabling the operator to more precisely control the rotation angle and displacement of the threaded rod. This precise adjustment helps to achieve fine adjustment and precise control of the positioning device, improving the accuracy of positioning. At the same time, the knob has a good operating feel and a smooth rotation action, making the adjustment process more comfortable and labor-saving.
[0020] Furthermore, the support plate is provided with a limiting groove in the vertical direction, and the first slider and the second slider are slidably connected with the limiting groove.
[0021] By adopting the above technical solution, by providing the limiting groove, the first slider and the second slider are restricted by forces in the horizontal direction, so that the two sliders will not rotate during the up and down process as the threaded rod rotates, and at the same time, the two sliders also have a certain amount of stroke in the vertical direction, improving the overall stability of the adjustment device.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. Integrate the integrated adjustment device on the outer wall of the template. The same adjustment device can adjust the orientations in different directions, simplifying the positioning adjustment steps and improving the work efficiency.

[0033] The following further describes the present application in detail with reference to the drawings.
[0034] Embodiment, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, A positioning device for the catenary of high-speed railways, comprising a template 1 and a rectangular channel steel frame 2. The rectangular channel steel frame 2 is welded into a rectangle by four channel steels. Two positioning steel plates 3 are respectively arranged at the upper and lower ends of the rectangular channel steel frame 2. The positioning steel plates 3 are circular rings. A plurality of anchor bolt 4 positioning holes are opened on both the rectangular channel steel frame 2 and the positioning steel plates 3. After a plurality of anchor bolts 4 sequentially pass through the anchor bolt 4 positioning holes of the rectangular channel steel frame 2 and the positioning steel plates 3, their positions are fixed. An adjusting device is arranged on the outer side wall of the template 1. The adjusting device includes a support plate 5 and a double-nut adjusting bolt 51. The cross-section of the support plate 5 in the vertical direction is in a "C" shape. The opening of the support plate 5 faces away from the template 1. One end of the double-nut adjusting bolt 51 is fixed to the template 1, and the other end is fixed to the support plate 5. Through holes 52 are opened on the upper and lower end faces of the support plate 5. The vertical and horizontal positioning adjustments are integrated in the same adjusting device. The operator does not need to operate the adjusting devices in multiple directions separately. Just by operating a single adjusting device, the overall adjustment of the positioning device can be achieved, greatly simplifying the adjustment steps and improving the work efficiency. Through the combination of the support plate 5, the double-nut adjusting bolt 51 and the adjusting plate 53, the positioning adjustment of the adjusting device in the direction of approaching and moving away from the template 1 side is realized. The design of the double-nut adjusting bolt 51 makes the adjustment process fast and accurate. By rotating the nut, the distance between the support plate 5 and the template 1 can be quickly adjusted. By controlling the telescopic length of the scissor mechanism 54 in the horizontal direction and its orientation in the vertical direction, the horizontal and vertical orientations of the adjusting plate 53 can be changed.
[0035] In this embodiment, the adjusting device further includes an adjusting plate 53. The upper end of the adjusting plate 53 is fixedly connected to the rectangular channel steel frame 2. The adjusting plate 53 is slidably connected in the through hole 52. The adjusting device further includes a scissor mechanism 54. A chute 530 is provided on the adjusting plate 53 in the vertical direction. One side upper end of the scissor mechanism 54 is hinged to the adjusting plate 53 and the lower end is slidably connected to the chute 530. The adjusting device further includes a threaded rod 55. The threaded rod 55 is arranged in the vertical direction. A first slider 56 and a second slider 57 are sleeved on the threaded rod 55. Both ends of one side of the scissor mechanism 54 are respectively hinged to the first slider 56 and the second slider 57, so as to realize the positioning adjustment of the anchor bolt 4. By rotating the threaded rod 55, the orientations of the first slider 56 and the second slider 57 in the vertical direction can be adjusted, thus simplifying the adjustment of the orientation of the scissor mechanism 54 and improving the convenience of the positioning adjustment operation. By setting a clutch device, the two sliders can not only move equidistantly and in the same direction in the vertical direction, but also fix the first slider 56 to realize the independent rising or falling of the second slider 57, making the two sliders move relatively, so as to realize the moving adjustment of the scissor mechanism 54 in both the vertical and horizontal directions on the same device, simplifying the structure of the positioning adjustment device and the process of the positioning operation.
[0036] In this embodiment, a clutch device is provided inside the first slider 56. The clutch device includes a threaded sleeve 58, which is threadedly connected to the threaded rod 55. The first slider 56 is sleeved on the threaded sleeve 58. A number of vertically oriented positioning grooves 580 are formed on the outer wall of the threaded sleeve 58. A driving block 581 is slidably connected inside the first slider 56. The driving block 581 is located outside the threaded sleeve 58. A limiting rod 582 is fixed to the side of the driving block 581 away from the threaded sleeve 58. The limiting rod 582 is slidably connected to the first slider 56. A through hole 560 is formed in the first slider 56 in the vertical direction. An unlocking plate 583 is slidably connected inside the through hole 560. An inclined unlocking groove 6 is formed on the unlocking plate 583. A protrusion 60 is fixed to the side of the driving block 581 close to the unlocking plate 583. The protrusion 60 is slidably connected to the unlocking groove 6. The clutch device further includes a compression spring 584, which is sleeved around the limiting rod 582. The threaded rod 55 is fixedly connected with a knob. A vertical limiting groove 50 is formed on the support plate 5. The first slider 56 and the second slider 57 are slidably connected to the limiting groove 50. When the clutch device needs to be unlocked, the unlocking plate 583 is moved. The protrusion of the driving block 581 slides in the unlocking groove 6, driving the driving block 581 to move towards the threaded sleeve 58. At the same time, the driving block 581 is squeezed into the positioning groove 580 on the threaded sleeve 58 under the action of the compression spring 584, playing a dual insurance role and also accelerating the process of the sliding engagement between the driving block 581 and the positioning groove 580, improving the fluency and stability of using the positioning device. The knob has relatively delicate adjustment scales, enabling the operator to more precisely control the rotation angle and displacement of the threaded rod 55. By providing the limiting groove 50, the first slider 56 and the second slider 57 are restricted by forces in the horizontal direction, so that the two sliders will not rotate during the up and down process as the threaded rod 55 rotates. At the same time, the two sliders also have a certain amount of travel in the vertical direction, improving the overall stability of the adjustment device.
[0037] Specific implementation process: First, place the template 1 at the reserved position where the anchor bolt 4 needs to be fixed. Place the welded rectangular channel steel frame 2 above the template 1. The anchor bolt 4 passes through the reserved hole positions of the anchor bolt 4 on the rectangular channel steel frame 2 and the positioning steel plates 3 to fixedly connect the two positioning steel plates 3 with the rectangular channel steel frame 2. When the positioning of the positioning steel plate 3 needs to be adjusted, adjust the double-nut adjusting bolt 51, and the support plate 5 can move in the direction close to or away from the side wall of the template 1. By rotating the knob below the threaded rod 55, the vertical positions of the first slider 56 and the second slider 57 can be adjusted, thereby driving the adjusting plate 53 to move up and down, realizing the positioning adjustment of the anchor bolt 4 in the vertical direction. By lifting the unlocking plate 583 in the clutch device, the driving block 581 disengages from the positioning groove 580. At this time, relative rotation can occur between the first slider 56 and the threaded sleeve 58. At this time, rotate the knob below the threaded rod 55, the first slider 56 is fixed in place, and the second slider 57 rises and falls independently, thereby controlling the expansion and contraction of the scissors mechanism 54 to realize the positioning adjustment of the positioning steel plate 3 in the horizontal direction. After the positioning of the anchor bolt 4 is completed, pour concrete into the template 1 to complete the construction.
[0038] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
