Description

Technical Field

[0001] This application relates to the field of rail transit technology, and more specifically, to an insulating support device and a contact rail system. Background Technology

[0002] Insulating support devices are mechanisms used to support and fix the contact rail in rail transit lines. For side current supply systems, the insulating support devices are installed on both sides of the track beam with the side surface of the beam as the mounting surface. The insulating support devices connect the contact rail and the beam and provide insulation between the contact rail and the beam. Due to errors in the manufacturing and installation of the beam, the mounting surface of the beam used to install the insulating support devices has varying degrees of error in the horizontal direction compared to the track center reference plane. Therefore, the insulating support devices need to be able to achieve linear adjustment in the horizontal direction. At the same time, in curved sections, the track center reference plane is tilted to varying degrees relative to the beam center plane. Since the position of the contact rail's current supply surface needs to be consistent with the track center reference plane, the insulating support devices need to be able to achieve pitch angle adjustment.

[0003] To achieve horizontal and pitch angle adjustment of the insulation support device, the device typically includes a base and an insulator. The clamping section at the rear end of the insulator is located within the clamping surface of the base and is secured by bolts. The bolts are accommodated by slotted holes on the insulator, allowing for both horizontal and pitch angle adjustment. In this type of insulation support device, both horizontal and pitch angle adjustments act on the clamping section of the insulator, and these two actions affect each other due to changes in position. In actual operation, adjusting one action requires considering the positional changes of the other adjustment mechanism; otherwise, adjustment jamming may occur, making the adjustment process extremely cumbersome. Summary of the Invention

[0004] This application provides an insulating support device that enables the horizontal and pitch angle adjustments of the insulator to be independent of each other, and the adjustment process is simple and convenient.

[0005] This application provides an insulating support device, which includes a mounting base, a movable base, an insulator, a first adjustment mechanism, and a second adjustment mechanism. The movable base is swayably disposed on the mounting base about a first axis arranged along a first direction. The insulator is adjustablely disposed on the movable base along a second direction. The first adjustment mechanism is connected to the mounting base and the movable base and is configured to adjust the angle of sway of the movable base about the first axis. The second adjustment mechanism is connected to the movable base and the insulator and is configured to adjust the position of the insulator in a second direction, wherein the first direction is perpendicular to the second direction.

[0006] In the above technical solution, the movable seat is oscillatingly mounted on the mounting base around a first axis. The angle of oscillation of the movable seat around the first axis can be adjusted by a first adjusting mechanism, thereby achieving pitch angle adjustment of the insulator. The insulator is adjustablely mounted on the movable seat along a second direction. The position of the insulator in the second direction can be adjusted by a second adjusting mechanism, thereby achieving horizontal adjustment of the insulator. The pitch angle adjustment and horizontal adjustment of the insulator are completed independently by the first and second adjusting mechanisms, respectively, without affecting each other, making the adjustment process simple and convenient. Furthermore, since the horizontal adjustment of the insulator is achieved by the second adjusting mechanism, compared to manually tapping the insulator to achieve horizontal adjustment, the operation is more convenient and labor-saving.

[0007] In some embodiments, the mounting base includes a first connecting portion and two first clamping portions; the two first clamping portions are disposed opposite each other along a first direction, and a first clamping gap is formed between the two first clamping portions, with the movable seat at least partially located within the first clamping gap; the first connecting portion connects the two first clamping portions; wherein the two first clamping portions have a first clamping state clamping the movable seat and a first relaxed state relaxing the movable seat, and a first adjusting mechanism is configured to adjust the angle of the movable seat swinging about a first axis when the two first clamping portions are in the first relaxed state.

[0008] In the above technical solution, since the movable seat is at least partially located within the first clamping gap, the overall volume of the movable seat and the mounting seat can be reduced, which is beneficial for miniaturizing the insulating support device. When the two first clamping parts clamp the movable seat, the movable seat can be fixed to the mounting seat, holding it in a certain swinging position; when the two first clamping parts release the movable seat, the movable seat can swing relative to the mounting seat, and the swing angle of the movable seat can be adjusted by the first adjusting mechanism. Furthermore, the two first clamping parts can restrict the movable seat in the first direction, improving the stability of the movable seat during its swing relative to the mounting seat.

[0009] In some embodiments, the movable seat includes a second connecting portion and two second clamping portions; the two second clamping portions are disposed opposite to each other along a first direction, forming a second clamping gap between the two second clamping portions, the insulator being at least partially located within the second clamping gap, and the two second clamping portions being located within a first clamping gap; the second connecting portion connects the two second clamping portions; wherein the two second clamping portions have a second clamped state clamping the insulator and a second relaxed state relaxing the insulator, and the second adjusting mechanism is configured to adjust the position of the insulator in a second direction when the two second clamping portions are in the second relaxed state.

[0010] In the above technical solution, since the insulator is at least partially located within the second clamping gap, the two second clamping parts clamp the insulator, thus fixing the insulator to the movable seat and holding the insulator in a certain position in the second direction. When the two second clamping parts release the insulator, the insulator can move relative to the movable seat, allowing the position of the insulator in the second direction to be adjusted via the second adjusting mechanism. This enables a wide range of insulator movement, which is beneficial for increasing the horizontal adjustment range of the insulator. Furthermore, since the two second clamping parts are located within the first clamping gap, when the two first clamping parts approach and clamp the two second clamping parts, the two second clamping parts can be brought closer together to clamp the insulator.

[0011] In some embodiments, the insulating support device further includes a locking mechanism configured to switch the two first clamping portions between a first clamping state and a first relaxed state; when the two first clamping portions are in the first clamping state, the two second clamping portions are in a second clamping state; when the two first clamping portions are in the first relaxed state, the two second clamping portions are in a second relaxed state.

[0012] In the above technical solution, the locking mechanism simultaneously clamps the movable seat with the two first clamping parts and the insulator with the two second clamping parts. In other words, a single locking mechanism can fix both the mounting base and the movable seat, as well as the insulator and the movable seat, resulting in a simple structure.

[0013] In some embodiments, the first clamping part is provided with a first through hole; the locking mechanism includes a first bolt and a first nut; the first bolt passes through the first through hole of the two first clamping parts; the first nut is threadedly engaged with the first bolt to realize the switching of the two first clamping parts between a first clamping state and a first loosening state.

[0014] In the above technical solution, tightening the first nut clamps the movable seat between the two first clamping parts and the insulator between the two second clamping parts. The first nut and the first bolt provide a large clamping force to the two first and two second clamping parts, thus fixing the mounting base, the movable seat, and the insulator. Loosening the first nut releases the movable seat from the two first clamping parts and the insulator from the two second clamping parts, allowing for adjustment of the insulator's pitch and horizontal angles via the first and second adjustment mechanisms, respectively. This locking mechanism is simple in structure and easy to operate.

[0015] In some embodiments, the second clamping part is provided with a second through hole, and the first bolt passes through the second through hole of the two second clamping parts; wherein, the first through hole is an arc-shaped hole extending along an arc trajectory, and the center of the arc trajectory is located on the first axis.

[0016] In the above technical solution, the first bolt passes through the first through hole and the second through hole, and the first through hole is an arc-shaped hole. When the first bolt swings with the movable seat, it will be restricted by the first through hole, so as to limit the swing range of the movable seat to a certain range.

[0017] In some embodiments, the second connecting portion is connected to one end of the second clamping portion along a third direction, and at least one end of the second clamping portion opposite to the second connecting portion along a third direction is provided with a first scale, and the first direction, the second direction and the third direction are perpendicular to each other.

[0018] In the above technical solution, the second connecting part is connected to one end of the second clamping part along the third direction, so that the part of the insulator clamped by the two second clamping parts and the second connecting part can be arranged along the third direction. The second connecting part will not affect the movement of the insulator in the second direction, thereby increasing the horizontal adjustment range of the insulator. In addition, the setting of the first scale can intuitively determine the accurate situation of the movable seat deviating from the initial installation position due to the swing relative to the mounting seat. This facilitates observation during operation and maintenance inspections, greatly improving the speed of operation and maintenance inspections and effectively improving inspection efficiency.

[0019] In some embodiments, the insulator includes an insulating body and a clamping segment extending in a second direction, the insulating body being connected to one end of the clamping segment, the clamping segment being at least partially located within a second clamping gap, and the clamping segment being provided with a second scale.

[0020] In the above technical solution, the setting of the second scale can intuitively determine the accurate situation of the insulator deviating from the initial installation position due to the movement of the relative movable seat along the second direction. This facilitates observation during operation and maintenance inspections, greatly improves the speed of operation and maintenance inspections, and effectively improves inspection efficiency.

[0021] In some embodiments, the insulating support device further includes a locking mechanism configured to: lock the mounting base, the movable seat, and the insulator; or, release the mounting base, the movable seat, and the insulator; the locking mechanism includes a first bolt and a first nut, the first bolt passing through the mounting base and the movable seat, and the first nut cooperating with the first bolt to lock or release the mounting base, the movable seat, and the insulator.

[0022] In the above technical solution, a locking mechanism can be used to lock or release the mounting base, movable base and insulator. The structure is simple and the adjustment is efficient.

[0023] In some embodiments, a first adjustment mechanism is connected to a first bolt, and the first adjustment mechanism is configured to directly pull the first bolt to cause the movable seat to swing relative to the mounting seat.

[0024] In the above technical solution, the first bolt serves both as a component for locking or loosening the mounting base, movable base, and insulator, and as a connecting component for connecting the first adjusting mechanism and the movable base, thus simplifying the structure of the insulation support device.

[0025] In some embodiments, the mounting base includes a first connecting portion, which is disposed opposite to the movable base along a second direction, and the first connecting portion is provided with a third through hole; the first adjusting mechanism includes a pull rod, a second nut, and a third nut; the pull rod is provided with a fourth through hole, and a first bolt passes through the fourth through hole to enable the pull rod to be oscillatingly connected to the movable base around a second axis arranged along the first direction, and the pull rod passes through the third through hole; the second nut and the third nut are both threadedly engaged with the pull rod, and the first connecting portion is at least partially located between the second nut and the third nut.

[0026] In the above technical solution, the swing angle of the movable seat can be adjusted bidirectionally by the second nut and the third nut. That is, by tightening one of the second nut and the third nut, the movable seat can swing forward; by tightening the other, the movable seat can swing backward. After adjusting the swing angle of the movable seat using the second nut or the third nut, the second nut and the third nut can be tightened so that they together clamp the first connecting part, thus holding the movable seat in the adjusted position. Furthermore, since the first bolt passes through the fourth through hole of the tie rod, the first bolt serves both as a locking component for securing the movable seat and the insulator and as a connecting component for allowing the tie rod to swing relative to the movable seat. This simplifies the structure of the insulation support device and reduces the number of parts in the insulation support device.

[0027] In some embodiments, the second adjusting mechanism includes a helical gear, a worm gear, and a rack; the helical gear is sleeved on the outside of the first bolt so that the helical gear is rotatably disposed on the movable seat about a second axis extending along the first direction; the worm gear is rotatably disposed on the movable seat, and the helical gear meshes with the worm gear; the rack is fixed to the insulator, the rack extends along the second direction, and the rack meshes with the helical gear.

[0028] In the above technical solution, since both the helical gear and the rack mesh with the worm, rotating the worm allows the helical gear to rotate relative to the movable seat, thereby causing the helical gear to drive the rack to move along the second direction, thus adjusting the position of the insulator in the second direction. This second adjustment mechanism is convenient and labor-saving, has a self-locking function, and reduces the rebound phenomenon caused by external forces. Furthermore, since the helical gear is sleeved on the outside of the first bolt, the first bolt serves both as a locking component for securing the movable seat and the insulator and as a connecting component for enabling the helical gear to rotate relative to the movable seat. This simplifies the structure of the insulation support device and reduces the number of parts in the insulation support device.

[0029] Secondly, embodiments of this application provide a contact rail system, including a beam, a contact rail, and an insulating support device provided in any of the embodiments of the first aspect; the beam, the insulating support device, and the contact rail are arranged along a second direction, with a mounting base installed on the beam and the contact rail installed on an insulator.

[0030] Beneficial effects:

[0031] Compared with the prior art, the present invention has the following beneficial technical effects:

[0032] 1. It has the most complete functions and simple structure to date, making full use of the existing structure of each part and achieving complete functions with fewer parts.

[0033] 2. It features a pioneering horizontal (front-back) adjustment mechanism, enabling active adjustment in the front-back direction. This completely eliminates the need for manual tapping, ensuring high precision and stability and filling a long-standing gap in the industry.

[0034] 3. The first and second adjustment mechanisms adopt an integrated design. The integrated front-to-back and pitch angle adjustment mechanisms do not interfere with each other, are simple to operate, and are stable and reliable.

[0035] 4. Display scales have been added for the forward and backward directions and the pitch angle, which can display the accurate position of the insulation support device in real time. This makes it easier to observe during operation and maintenance inspections. Instead of having to use tools to check each support position, we can now conduct spot checks on those with no change in scale, which greatly improves the speed of operation and maintenance inspections and increases inspection efficiency several times over.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0050] Please refer to Figure 1 , Figure 1 The present application provides a structural schematic diagram of a contact rail system 100 for some embodiments. The contact rail system 100 may include an insulating support device 10, a contact rail 20, and a beam 30. The insulating support device 10 connects the contact rail 20 and the beam 30.

[0051] The beam 30 is a load-bearing component, and the wiring can be arranged on the top of the beam 30. The side surface of the beam 30 is the mounting surface 31, and the insulating support device 10 is installed on the mounting surface 31.

[0052] As an example, an insulating support device 10 is installed on each of the two mounting surfaces 31 opposite to the beam 30, and the contact rail 20 corresponds one-to-one with the insulating support device 10.

[0053] The contact rail 20 can also be called a conductive rail. The contact rail 20 is installed on the insulating support device 10, and the contact rail 20 and the beam 30 are insulated from each other through the insulating support device 10.

[0054] In this embodiment, the insulating support device 10 is a component that connects the beam 30 and the contact rail 20, and insulates the contact rail 20 from the beam 30. The insulating support device 10 has pitch angle adjustment and horizontal adjustment functions to achieve pitch angle and horizontal adjustment of the contact rail 20, so as to meet the usage requirements of the contact rail 20 in different scenarios. The specific structure of the insulating support device 10 is described in detail below with reference to the accompanying drawings.

[0055] Please refer to Figure 2 , Figure 2This is a schematic diagram of the structure of an insulating support device 10 provided in some embodiments of this application. The insulating support device 10 includes a mounting base 1, a movable base 2, an insulator 3, a first adjustment mechanism 4, and a second adjustment mechanism 5. The movable base 2 is pivotally mounted on the mounting base 1 about a first axis W arranged along a first direction X. The insulator 3 is adjustablely mounted on the movable base 2 along a second direction Y. The first adjustment mechanism 4 is connected to the mounting base 1 and the movable base 2, and is configured to adjust the angle of pivot of the movable base 2 about the first axis W. The second adjustment mechanism 5 is connected to the movable base 2 and the insulator 3, and is configured to adjust the position of the insulator 3 in the second direction Y, where the first direction X is perpendicular to the second direction Y.

[0056] The mounting base 1 is a component of the insulating support device 10 used for connection with the beam 30. The mounting base 1 can be fixed to the beam 30 by means of connectors, such as bolts or screws.

[0057] The movable seat 2 is a swinging component connected to the mounting seat 1. The pitch angle of the insulator 3 is adjusted by the swinging of the movable seat 2 relative to the mounting seat 1. The movable seat 2 and the mounting seat 1 are rotatably connected by a rotating shaft 6, allowing the movable seat 2 to swing. The centerline of the rotating shaft 6 is the first axis W. As an example, the rotating shaft 6 is a bolt passing through the movable seat 2 and the mounting seat 1.

[0058] Insulator 3 is made of insulating material, such as rubber, plastic, or ceramic. Insulator 3 is used to install contact rail 20, ensuring insulation between contact rail 20 and movable seat 2, and consequently, between contact rail 20 and beam 30. To facilitate installation of contact rail 20, a clamp 7 can be provided on insulator 3, which engages with contact rail 20 to complete the installation.

[0059] The insulator 3 is adjustablely positioned on the movable base 2 along the second direction Y, allowing the insulator 3 to move relative to the movable base 2 along the second direction Y. The insulator 3 can be adjusted in various ways along the second direction Y. For example, the insulator 3 can be provided with a slider, and the movable base 2 can be provided with a groove that slides with the slider; or the movable base 2 can have a guide space extending along the second direction Y, and the insulator 3 can be at least partially movably inserted into the guide space.

[0060] The first adjustment mechanism 4 is a driving component connected between the mounting base 1 and the movable base 2. The first adjustment mechanism 4 can adjust the angle of the movable base 2's swing around the first axis W, thereby adjusting the pitch angle of the insulator 3 and consequently the pitch angle of the contact rail 20. The first adjustment mechanism 4 can be a manual, electric, or pneumatic adjustment mechanism. It should be noted that after adjusting the position of the movable base 2 using the first adjustment mechanism 4, the movable base 2 can be fixed in the adjusted position by the first adjustment mechanism 4, or a locking mechanism 8 can be separately provided to lock the movable base 2 and the mounting base 1, thereby fixing the movable base 2 in the adjusted position.

[0061] The second adjusting mechanism 5 is a driving component connected between the insulator 3 and the movable seat 2. The second adjusting mechanism 5 can adjust the position of the insulator 3 in the second direction Y, thereby achieving horizontal adjustment of the insulator 3 and consequently, horizontal adjustment of the contact rail 20. The second adjusting mechanism 5 can be a manual, electric, or pneumatic adjusting mechanism. It should be noted that after adjusting the position of the insulator 3 using the second adjusting mechanism 5, the insulator 3 can be held in the adjusted position by the second adjusting mechanism 5, or a separate locking mechanism 8 can be provided to lock the insulator 3 and the movable seat 2, thereby fixing the insulator 3 in the adjusted position.

[0062] Combination Figure 1 and Figure 2 After the mounting base 1 is installed on the beam 30 and the contact rail 20 is installed on the insulator 3, the beam 30, the insulating support device 10 and the contact rail 20 can be arranged along the second direction Y. Along the second direction Y, the two contact rails 20 located on both sides of the beam 30 can be installed on the beam 30 through the two insulating support devices 10 respectively.

[0063] In this embodiment, the movable seat 2 is oscillatingly mounted on the mounting base 1 around the first axis W. The first adjusting mechanism 4 can adjust the oscillation angle of the movable seat 2 around the first axis W, thereby adjusting the pitch angle of the insulator 3 and consequently, the pitch angle of the contact rail 20. The insulator 3 is adjustablely mounted on the movable seat 2 along the second direction Y. The second adjusting mechanism 5 can adjust the position of the insulator 3 in the second direction Y, thereby adjusting the horizontal position of the insulator 3 and consequently, the horizontal position of the contact rail 20. The pitch angle adjustment and horizontal adjustment of the insulator 3 are performed independently by the first adjusting mechanism 4 and the second adjusting mechanism 5, without affecting each other, making the adjustment process simple and convenient. Furthermore, since the horizontal adjustment of the insulator 3 is achieved by the second adjusting mechanism 5, compared to manually tapping the insulator 3 to achieve horizontal adjustment, the operation is more convenient and labor-saving.

[0064] Please refer to Figure 3 and Figure 4 , Figure 3 for Figure 2 The assembly diagram of the mounting base 1, the movable base 2, and the first adjustment mechanism 4 is shown. Figure 4 for Figure 3 The diagram shows the structure of the mounting base 1. The mounting base 1 may include a first connecting portion 11 and two first clamping portions 12. Along a first direction X, the two first clamping portions 12 are arranged opposite to each other, forming a first clamping gap 13 between them. The movable seat 2 is at least partially located within the first clamping gap 13. The first connecting portion 11 connects the two first clamping portions 12. The two first clamping portions 12 have a first clamped state that clamps the movable seat 2 and a first relaxed state that relaxes the movable seat 2. The first adjusting mechanism 4 is configured to adjust the angle of the movable seat 2's swing about a first axis W when the two first clamping portions 12 are in the first relaxed state.

[0065] The two first clamping parts 12 are the parts of the mounting base 1 that clamp the movable base 2. If the two first clamping parts 12 clamp the movable base 2, the two first clamping parts 12 are in the first clamping state. At this time, the movable base 2 is fixed to the mounting base 1, and the movable base 2 cannot swing relative to the mounting base 1. If the two first clamping parts 12 release the movable base 2, the two first clamping parts 12 are in the first relaxed state. At this time, the movable base 2 is not fixed to the mounting base 1, and the movable base 2 can swing relative to the mounting base 1 under the drive of the first adjusting mechanism 4 to achieve the adjustment of the pitch angle of the insulator 3.

[0066] As an example, the first clamping part 12 can be a plate-like structure. Along the first direction X, the two first clamping parts 12 have clamping surfaces 121 facing each other. To increase the friction between the two first clamping parts 12 and the movable seat 2 when clamping the movable seat 2, anti-slip protrusions 122 can be provided on the clamping surfaces 121 of the first clamping parts 12. For example, multiple anti-slip protrusions 122 are provided on the clamping surfaces 121. The anti-slip protrusions 122 are strip-shaped structures, and the multiple anti-slip protrusions 122 are arranged at intervals along the second direction Y.

[0067] The movable seat 2 can be completely or partially located within the first clamping gap 13. Figure 3 In the illustrated embodiment, the movable seat 2 is completely located within the first clamping gap 13 to enhance the clamping force of the two first clamping parts 12 on the movable seat 2 in the first clamping state.

[0068] The first connecting part 11 serves to connect the two first clamping parts 12. The first connecting part 11 can elastically deform when the two first clamping parts 12 come close to each other. The first connecting part 11 can be a flat plate structure or a bent structure.

[0069] As an example, the first connecting part 11 and the movable seat 2 are arranged opposite each other along the second direction Y, and the first adjusting mechanism 4 is connected between the first connecting part 11 and the movable seat 2. This makes it easier for the first adjusting mechanism 4 to adjust the movable seat 2.

[0070] As an example, the first connecting portion 11 and the two first clamping portions 12 form a U-shaped structure. The first connecting portion 11 partially protrudes towards the movable seat 2 to form a protrusion 111, and a recess 112 is formed on the side of the first connecting portion 11 facing away from the movable seat 2. The protrusion 111 is located within the first clamping gap 13. This bent structure of the first connecting portion 11 gives it better resistance to deformation and damage, improving the overall load-bearing capacity of the mounting base 1.

[0071] In this embodiment, since the movable seat 2 is at least partially located within the first clamping gap 13, the overall volume of the movable seat 2 and the mounting seat 1 can be reduced, which is beneficial for miniaturizing the insulating support device 10. When the two first clamping parts 12 clamp the movable seat 2, the movable seat 2 can be fixed to the mounting seat 1, thus holding the movable seat 2 in a certain swinging position; when the two first clamping parts 12 release the movable seat 2, the movable seat 2 can swing relative to the mounting seat 1, and the swing angle of the movable seat 2 can be adjusted by the first adjusting mechanism 4. Furthermore, the two first clamping parts 12 can restrict the movable seat 2 in the first direction X, improving the stability of the movable seat 2 during its swing relative to the mounting seat 1.

[0072] In some embodiments, please continue to refer to Figure 3 and Figure 4 The mounting base 1 may further include two mounting portions 14, each mounting portion 14 corresponding to a first clamping portion 12. The mounting portions 14 and the first clamping portions 12 form an L-shaped structure. The mounting portions 14 are located on the side of the first clamping portions 12 opposite to the first clamping gap 13 along the first direction X. The mounting portions 14 and the first clamping portions 12 are connected by reinforcing ribs 15.

[0073] Mounting part 14 is the portion of mounting base 1 used for connection with beam 30. As an example, mounting part 14 is a plate-like structure, and it is provided with mounting holes 141 to facilitate mounting of mounting part 14 to beam 30 using bolts or screws. Mounting part 14 and first clamping part 12 are perpendicular, forming an L-shaped structure. Mounting part 14, first clamping part 12, and first connecting part 11 are integrally formed.

[0074] As an example, the reinforcing rib 15 is a strip-shaped piece, with one end of the reinforcing rib 15 welded to the first clamping part 12 and the other end of the reinforcing rib 15 welded to the mounting part 14.

[0075] In this embodiment, the mounting part 14 facilitates the installation of the mounting base 1 and the beam 30. The mounting part 14 and the first clamping part 12 form an L-shaped structure, and a reinforcing rib 15 is provided between the mounting part 14 and the first clamping part 12. The reinforcing rib 15 can improve the connection strength between the mounting part 14 and the first clamping part 12, thereby improving the load-bearing capacity of the entire mounting base 1.

[0076] Please refer to Figures 3-5 , Figure 5 for Figure 3 The diagram shows the structure of the movable base 2. The movable base 2 includes a second connecting portion 21 and two second clamping portions 22. Along the first direction X, the two second clamping portions 22 are arranged opposite to each other, forming a second clamping gap 23 between them. The insulator 3 is at least partially located within the second clamping gap 23, and the two second clamping portions 22 are located within a first clamping gap 13. The second connecting portion 21 connects the two second clamping portions 22. The two second clamping portions 22 have a second clamped state that clamps the insulator 3 and a second relaxed state that relaxes the insulator 3. The second adjusting mechanism 5 is configured to adjust the position of the insulator 3 in the second direction Y when the two second clamping portions 22 are in the second relaxed state.

[0077] The two second clamping parts 22 are the parts of the movable seat 2 that clamp the insulator 3. If the two second clamping parts 22 clamp the insulator 3, the two second clamping parts 22 are in the second clamping state. At this time, the insulator 3 and the movable seat 2 are fixed, and the insulator 3 cannot move relative to the movable seat 2 in the second direction Y. If the two second clamping parts 22 loosen the insulator 3, the two second clamping parts 22 are in the second loosening state. At this time, the insulator 3 and the movable seat 2 are not fixed, and the insulator 3 can move relative to the movable seat 2 in the second direction Y under the drive of the second adjusting mechanism 5, so as to realize the horizontal adjustment of the insulator 3.

[0078] The second connecting portion 21 serves to connect the two second clamping portions 22, and the second connecting portion 21 can deform when the two second clamping portions 22 approach each other. As an example, the second connecting portion 21 and the two second clamping portions 22 are integrally formed.

[0079] In this embodiment, since the insulator 3 is at least partially located within the second clamping gap 23, the two second clamping parts 22 clamp the insulator 3, thus fixing the insulator 3 to the movable seat 2 and holding the insulator 3 at a certain position in the second direction Y. When the two second clamping parts 22 release the insulator 3, the insulator 3 can move relative to the movable seat 2, thereby allowing the position of the insulator 3 in the second direction Y to be adjusted via the second adjusting mechanism 5. This enables a wide range of movement of the insulator 3, which is beneficial for increasing the horizontal adjustment range of the insulator 3. Furthermore, since the two second clamping parts 22 are located within the first clamping gap 13, when the two first clamping parts approach and clamp the two second clamping parts 22, the two second clamping parts 22 can move closer together to clamp the insulator 3.

[0080] In some embodiments, please continue to refer to Figure 5 The second connecting part 21 is connected to one end of the second clamping part 22 along the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0081] The second connecting part 21 and the two second clamping parts 22 can form a U-shaped structure, the opening of which is disposed opposite to the second connecting part 21 along the third direction Z.

[0082] In this embodiment, the second connecting part 21 is connected to one end of the second clamping part 22 along the third direction Z, so that the part of the insulator 3 clamped by the two second clamping parts 22 and the second connecting part 21 can be arranged along the third direction Z. The second connecting part 21 will not affect the movement of the insulator 3 in the second direction Y, thereby increasing the horizontal adjustment range of the insulator 3.

[0083] It should be noted that in other embodiments, the second connecting part 21 may also be connected to other positions of the second clamping part 22, for example, the second connecting part 21 may be connected to one end of the second clamping part 22 along the second direction Y.

[0084] In some embodiments, at least one second clamping portion 22 is provided with a first scale 221 at one end of the second connecting portion 21 in a third direction Z.

[0085] It is understandable that either one of the second clamping parts 22 may be provided with the first scale 221, or both of the second clamping parts 22 may be provided with the first scale 221. Figure 5 In the illustrated embodiment, each of the two second clamping portions 22 is provided with a first scale 221 at one end of the second connecting portion 21 in the third direction Z.

[0086] In practical use, after the contact rail 20 is installed on the beam 30 via the insulating support device 10, the initial installation position of the movable seat 2 can be recorded by scribing. If the movable seat 2 deviates from the initial installation position after a period of use, the amount of deviation of the scribing line can be determined by using the first scale 221.

[0087] In this embodiment, the setting of the first scale 221 can intuitively determine the accurate situation of the movable seat 2 deviating from the initial installation position due to the swinging relative to the mounting seat 1. This makes it easy to observe during operation and maintenance inspections, greatly improving the speed of operation and maintenance inspections and effectively improving inspection efficiency.

[0088] Please refer to Figure 2 and Figure 6 , Figure 6 for Figure 2 The diagram shows the structure of the insulator 3. The insulator 3 includes an insulating body 31 and a clamping section 32. The clamping section 32 extends along the second direction Y. The insulating body 31 is connected to one end of the clamping section 32. The clamping section 32 is at least partially located within the second clamping gap 23. The clamping section 32 is provided with a second scale 321.

[0089] The insulating body 31 is the part of the insulator 3 used to install the contact rail 20, and the clamping section 32 is the part of the insulator 3 for the two second clamping parts 22 of the movable seat 2 to clamp. As an example, the insulating body 31 and the clamping section 32 are integrally formed, the insulating body 31 is a rotating body, the clamping section 32 is cylindrical, and the insulating body 31 and the clamping section 32 are coaxially arranged.

[0090] In practical use, after the contact rail 20 is installed on the beam 30 via the insulating support device 10, the initial installation position of the insulator 3 can be recorded by scribing. If, after a period of use, the insulator 3 deviates from its initial installation position, the offset of the scribing line can be determined by using the second scale 321, thus determining the amount of deviation of the insulator 3 from its initial installation position.

[0091] In this embodiment, the setting of the second scale 321 can intuitively determine the accurate situation of the insulator 3 deviating from the initial installation position due to the relative movement of the movable seat 2 along the second direction Y. This facilitates observation during operation and maintenance inspections, greatly improves the speed of operation and maintenance inspections, and effectively improves inspection efficiency.

[0092] In some embodiments, please continue to refer to Figure 5 The two second clamping parts 22 have receiving grooves 222 on their surfaces facing each other. The receiving grooves 222 are used to receive the clamping section 32 of the insulator 3. The shape of the receiving grooves 222 matches the shape of the clamping section 32 to increase the contact area between the second clamping parts 22 and the clamping section 32, so as to clamp the clamping section 32 more firmly.

[0093] In actual use, the receiving groove 222 can be set according to the shape of the clamping section 32 to accommodate different types of insulators 3.

[0094] In some embodiments, please continue to refer to Figure 3 The insulating support device 10 may also include a locking mechanism 8, which is configured to: lock the mounting base 1, the movable base 2 and the insulator 3; or, release the mounting base 1, the movable base 2 and the insulator 3.

[0095] Specifically, the locking mechanism 8 is configured to switch between a first clamping state and a first loosening state for the two first clamping parts 12. When the two first clamping parts 12 are in the first clamping state, the two second clamping parts 22 are in the second clamping state to lock the mounting base 1, the movable base 2, and the insulator 3; when the two first clamping parts 12 are in the first loosening state, the two second clamping parts 22 are in the second loosening state to loosen the mounting base 1, the movable base 2, and the insulator 3.

[0096] In this embodiment, the locking mechanism 8 can switch between the two first clamping parts 12 in the first clamping state and the first loosening state, and can also switch between the two second clamping parts 22 in the second clamping state and the second loosening state.

[0097] The locking mechanism 8 can have various structures, as long as it can apply clamping force from the two first clamping parts 12 to the two second clamping parts 22. For example, the locking mechanism 8 can be a bolt and nut structure, which uses the bolt and nut to clamp the two first clamping parts 12 and the two second clamping parts 22; or, the locking mechanism 8 can be a binding member, which binds the two first clamping parts 12 together, thus clamping both the two first clamping parts 12 and the two second clamping parts 22.

[0098] In this embodiment, the locking mechanism 8 enables the two first clamping parts 12 to clamp the movable seat 2 while simultaneously enabling the two second clamping parts 22 to clamp the insulator 3. In other words, the locking mechanism 8 can fix both the mounting base 1 and the movable seat 2, as well as the insulator 3 and the movable seat 2, resulting in a simple structure.

[0099] In some embodiments, please continue to refer to Figure 3 and Figure 4 The first clamping part 12 is provided with a first through hole 123. The locking mechanism 8 includes a first bolt 81 and a first nut 82. The first bolt 81 passes through the first through hole 123 of the two first clamping parts 12. The first nut 82 is threadedly engaged with the first bolt 81 to realize the switching of the two first clamping parts 12 between a first clamping state and a first loosening state.

[0100] In this embodiment, the first through hole 123 can be a round hole, a square hole, a strip hole, an arc hole, etc. The first bolt 81 can pass through the second clamping part 22 of the movable seat 2, or it can not pass through the second clamping part 22 of the movable seat 2. If the first bolt 81 passes through the second clamping part 22 of the movable seat 2, a through hole for the first bolt 81 to pass through can be provided on the second clamping part 22 of the movable seat 2.

[0101] In this embodiment, tightening the first nut 82 causes the two first clamping parts 12 to clamp the movable seat 2 and the two second clamping parts 22 to clamp the insulator 3. The first nut 82 and the first bolt 81 work together to provide a large clamping force for the two first clamping parts 12 and the two second clamping parts 22, thus fixing the mounting base 1, the movable seat 2, and the insulator 3. Loosening the first nut 82 causes the two first clamping parts 12 to release the movable seat 2 and the two second clamping parts 22 to release the insulator 3, so that the pitch angle and horizontal adjustment of the insulator 3 can be adjusted by the first adjustment mechanism 4 and the second adjustment mechanism 5, respectively. This locking mechanism 8 has a simple structure and is easy to operate.

[0102] In some embodiments, please continue to refer to Figure 5 The second clamping part 22 is provided with a second through hole 223, and the first bolt 81 passes through the second through hole 223 of the two second clamping parts 22. The first nut 82 and the first bolt 81 cooperate to realize the switching of the second clamping part 22 between the second clamping state and the second loosening state.

[0103] The first through hole 123 can be an arc-shaped hole extending along an arc trajectory, with the center of the arc trajectory located on the first axis W. The second through hole 223 can be a circular hole that matches the first bolt 81.

[0104] In this embodiment, the first bolt 81 passes through the first through hole 123 and the second through hole 223, and the first through hole 123 is an arc-shaped hole. When the first bolt 81 swings with the movable seat 2, it will be restricted by the first through hole 123, so as to limit the swing range of the movable seat 2 to a certain range.

[0105] As can be seen from the above embodiments, a single locking mechanism 8 can simultaneously clamp the two first clamping parts 12 and the two second clamping parts 22. In other embodiments, two locking mechanisms 8 can also be provided: one locking mechanism 8 is used to switch the two first clamping parts 12 between a first clamping state and a first relaxed state, and the other locking mechanism 8 is used to switch the two second clamping parts 22 between a second clamping state and a second relaxed state.

[0106] In some embodiments, the locking mechanism 8 may further include a second bolt 83 and a fourth nut 84. The second bolt 83 passes through a through hole in the first clamping part 12 and the second clamping part 22. The fourth nut 84 cooperates with the second bolt 83 to lock or loosen the mounting base 1, the movable base 2, and the insulator 3. The centerline of the second bolt 83 is the first axis W. Thus, the cooperation of the fourth nut 84 and the second bolt 83, as well as the cooperation of the first nut 82 and the first bolt 81, further enhances the secureness of the mounting base 1, the movable base 2, and the insulator 3 after locking.

[0107] It is understood that in this embodiment, the second bolt 83 is the pivot 6 that enables the movable seat to swing relative to the mounting seat 1.

[0108] In some embodiments, the first adjustment mechanism 4 is connected to the first bolt 81 and is configured to directly pull the first bolt 81 to cause the movable seat 2 to swing relative to the mounting seat 1.

[0109] In this embodiment, the first bolt 81 serves both as a component for locking or releasing the mounting base 1, the movable base 2, and the insulator 3, and as a connecting component for connecting the first adjusting mechanism 4 and the movable base 2, thus simplifying the structure of the insulating support device 10.

[0110] In some embodiments, please continue to refer to Figure 3 , Figure 4 and Figure 7 The first connecting part 11 and the movable seat 2 are arranged opposite each other along the second direction Y. The first connecting part 11 is provided with a third through hole 113. The first adjusting mechanism 4 may include a pull rod 41, a second nut 42 and a third nut 43. The pull rod 41 is provided with a fourth through hole 4121, and a first bolt 81 passes through the fourth through hole 4121 to realize that the pull rod 41 is swayably connected to the movable seat 2 about a second axis V arranged along the first direction X. The pull rod 41 passes through the third through hole 113. The second nut 42 and the third nut 43 are both threadedly engaged with the pull rod 41, and the first connecting part 11 is at least partially located between the second nut 42 and the third nut 43.

[0111] In this embodiment, the second axis V is the center line of the first bolt 81.

[0112] The third through hole 113 on the first connecting part 11 can be a strip-shaped hole that allows the pull rod 41 to swing, and the fourth through hole 4121 on the pull rod 41 can be a circular hole that mates with the first bolt 81.

[0113] Since the first connecting part 11 and the movable seat 2 are arranged opposite each other along the second direction Y, the first connecting part 11 may affect the movement of the insulator 3 along the second direction Y. Therefore, a through hole can be provided at the position of the first connecting part 11 corresponding to the clamping section 32 of the insulator 3, so that the clamping section 32 can pass through.

[0114] As an example, the second nut 42 is located on the side of the first connecting part 11 facing the movable seat 2, and the third nut 43 is located on the side of the first connecting part 11 away from the movable seat 2. The part of the pull rod 41 that is away from the first bolt 81 that protrudes from the third through hole 113 is accommodated in the recess 112 of the first connecting part 11, and the third nut 43 is accommodated in the recess 112 of the first connecting part 11, so as to avoid the pull rod 41 and the third nut 43 affecting the installation of the mounting base 1.

[0115] As an example, the pull rod 41 may include a rod portion 411 and a head 412. The head 412 is provided with a slot 4122 and two fourth through holes 4121. The two fourth through holes 4121 are coaxially arranged along the first direction X, and are located on both sides of the slot 4122 and communicate with the slot 4122. One end of the rod portion 411 is connected to the head 412, and the other end passes through the third through hole 113. The second nut 42 and the third nut 43 are both threaded into the rod portion 411.

[0116] In this embodiment, the swing angle of the movable seat 2 can be adjusted bidirectionally by the second nut 42 and the third nut 43. That is, by turning one of the second nut 42 and the third nut 43, the movable seat 2 can swing in the forward direction, and by turning the other one, the movable seat 2 can swing in the reverse direction. After adjusting the swing angle of the movable seat 2 by the second nut 42 or the third nut 43, the second nut 42 and the third nut 43 can be tightened so that the second nut 42 and the third nut 43 together clamp the first connecting part 11 to hold the movable seat 2 in the adjusted position. In addition, since the first bolt 81 passes through the fourth through hole 4121 of the pull rod 41, the first bolt 81 is both a locking component for locking the movable seat 2 and the insulator 3 and a connecting component for allowing the pull rod 41 to swing relative to the movable seat 2. This simplifies the structure of the insulating support device 10 and reduces the number of parts in the insulating support device 10.

[0117] As can be seen from the above embodiments, the pull rod 41 can be connected to the movable seat 2 via the first bolt 81 to enable the pull rod 41 to swing. In other embodiments, the pull rod 41 can also be connected to the movable seat 2 via other components. For example, the pull rod 41 and the movable seat 2 can be rotatably connected via a first shaft, the center line of which is the second axis V, and the first shaft can be set parallel to the first bolt 81.

[0118] It should be noted that, in the embodiments of this application, the first adjustment mechanism 4 is not limited to the structure described above. The first adjustment mechanism 4 can also be other structures. For example, the first adjustment mechanism 4 includes a wedge, which is inserted into the gap between the movable seat 2 and the first connecting part 11 to adjust the swing angle of the movable seat 2. Alternatively, the first adjustment mechanism 4 includes two links, which, together with the movable seat 2 and the mounting seat 1, form a four-bar linkage mechanism. By changing the angle between the two links, the swing angle of the movable seat 2 can be adjusted.

[0119] In some embodiments, please refer to Figure 8 The second adjusting mechanism 5 may include a helical gear 51, a worm gear 52, and a rack 53. The helical gear 51 is sleeved on the outside of the first bolt 81, so that the helical gear 51 is rotatably mounted on the movable seat 2 about a second axis V arranged along the first direction X. The worm gear 52 is rotatably mounted on the movable seat 2, and the helical gear 51 meshes with the worm gear 52. The rack 53 is fixed to the insulator 3, extends along the second direction Y, and meshes with the helical gear 51.

[0120] The worm gear 52 can be directly mounted to the movable seat 2 or indirectly mounted to it. As an example, the worm gear 52 is indirectly mounted to the movable seat 2 via a worm gear seat 54. The worm gear seat 54 is detachably connected to the movable seat 2, and the worm gear 52 is rotatably mounted on the worm gear seat 54 about its own axis. The worm gear seat 54 can be detached from the movable seat 2 using screws. It should be noted that the worm gear seat 54 can be mounted to one of the two second clamping parts 22 using screws, or it can be mounted to both second clamping parts 22 simultaneously. Figure 8 As shown, in the embodiment where the worm gear seat 54 is installed on the two second clamping parts 22 by screws, the worm gear seat 54 can be connected to one second clamping part 22 by a first screw 55 and to the other second clamping part 22 by a second screw 56. The through hole on the worm gear seat 54 through which the first screw 55 passes can be set as a strip hole, which extends along the first direction X. In this way, after loosening the first screw 55, the worm gear seat 54 will not affect the two second clamping parts 22, ensuring that the two second clamping parts 22 can clamp or loosen the insulator 3 normally.

[0121] As an example, the rotation axis of the worm 52 is perpendicular to the second axis V. Specifically, the rotation axis of the worm 52 extends along a third direction Z, with the first direction X, the second direction Y, and the third direction Z being perpendicular to each other. Along the third direction Z, the worm 52 is located at the end of the movable seat 2 away from the second connecting part 21 to facilitate operation of the worm 52.

[0122] As an example, the helical gear 51 is located in the slot 4122 of the tie rod 41. The slot 4122 can limit the helical gear 51 and reduce the risk of the helical gear 51 moving along the first direction X on the first bolt 81.

[0123] As an example, rack 53 is fixed to clamping section 32 of insulator 3.

[0124] In this embodiment, since both the helical gear 51 and the rack 53 mesh with the worm 52, rotating the worm 52 allows the helical gear 51 to rotate relative to the movable seat 2, thereby causing the helical gear 51 to drive the rack 53 to move along the second direction Y, thus adjusting the position of the insulator 3 in the second direction Y. This second adjustment mechanism 5 is convenient and labor-saving to adjust, and has a self-locking function, reducing the rebound phenomenon caused by external forces. Since the helical gear 51 is sleeved on the outside of the first bolt 81, the first bolt 81 is both a locking component for locking the movable seat 2 and the insulator 3 and a connecting component for realizing the rotation of the helical gear 51 relative to the movable seat 2. This simplifies the structure of the insulation support device 10 and reduces the number of parts in the insulation support device 10.

[0125] As can be seen from the above embodiments, the helical gear 51 can be connected to the movable seat 2 via the first bolt 81 to achieve a rotatable connection between the helical gear 51 and the movable seat 2. In other embodiments, the helical gear 51 can also be rotatably connected to the movable seat 2 via a second shaft, which is parallel to the first bolt 81. Of course, the second shaft referred to here can be the same shaft as the first shaft in the aforementioned embodiments, or they can be two different shafts.

[0126] It should be noted that, in this embodiment, the second adjustment mechanism 5 is not limited to the structure described above. The second adjustment mechanism 5 can also be other structures. For example, the helical gear 51 in the second adjustment mechanism 5 described above can be replaced with a worm gear, and a gear can be added that is coaxially arranged with the worm gear and fixed to it. The worm 52 meshes with the worm gear, and the gear meshes with the rack 53. Alternatively, the second adjustment mechanism 5 includes a gear, a rack, and a drive shaft. The rack is fixed to the insulator 3, the gear is coaxially arranged with the drive shaft and fixed, the drive shaft extends along the first direction X, and the drive shaft is rotatably arranged on the movable seat 2 around its own axis. The gear and the rack mesh, and the horizontal adjustment of the insulator 3 can be achieved by rotating the drive shaft.

[0127] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
