Description

Technical Field

[0001] The present application relates to the technical field of railway overhead lines, and in particular to an insulating spacer. Background Art

[0002] Railway overhead lines are widely used in railway underpass construction, railway emergency reinforcement and other engineering fields. According to the site conditions and technical conditions, there are various structural forms and operation methods. The overhead technical solution of the horizontal beam method for underpass of rails is widely used due to its clear force, mature technology, simple operation and strong applicability.

[0003] In the current conventional overhead cross beam system, the cross beam is the main load-bearing component, which is inserted between the sleepers and under the sleepers to transfer the load to the stable foundation on both sides of the railway track. The cross beam generally adopts an I-beam structure, which is orthogonal to the rails and passes under the rails along the excavated ballast groove to bear the railway load. If the rails directly intersect with the I-beam cross beam, it will cause the current path of the two rails, send out an error signal, and cause a railway safety accident; the current more commonly used technical solution is to set wooden pads at the intersection position, which plays the role of insulation, buffering and dispersing pressure. When the height needs to be adjusted, one or more pads need to be added to the wooden pads to enable the pads to support the rails more stably on the cross beams, but the minimum design thickness of the pads will be limited, which can easily lead to the inability to accurately fill the height difference between the rails and the cross beams after adding multiple pads, thereby affecting the support stability of the cross beams on the rails.

DETAILED DESCRIPTION

[0038] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0040] Railway overhead lines are widely used in railway underpass construction, railway emergency reinforcement and other engineering fields. According to the site conditions and technical conditions, there are various structural forms and operation methods. The overhead technical solution of the horizontal beam method for underpass of rails is widely used due to its clear force, mature technology, simple operation and strong applicability.

[0041] In the current conventional overhead cross beam system, the cross beam is the main load-bearing component, which is inserted between the sleepers and under the sleepers to transfer the load to the stable foundation on both sides of the railway track. The cross beam generally adopts an I-beam structure, which is orthogonal to the rails and passes under the rails along the excavated ballast groove to bear the railway load. If the rails directly intersect with the I-beam cross beam, it will cause the current path of the two rails, send out an error signal, and cause a railway safety accident; the current more commonly used technical solution is to set wooden pads at the intersection position, which plays the role of insulation, buffering and dispersing pressure. When the height needs to be adjusted, one or more pads need to be added to the wooden pads to enable the pads to support the rails more stably on the cross beams, but the minimum design thickness of the pads will be limited, which can easily lead to the inability to accurately fill the height difference between the rails and the cross beams after adding multiple pads, thereby affecting the support stability of the cross beams on the rails.

[0042] Based on this, the present embodiment provides an insulating pad, which can change the relative distance between the first support surface and the second support surface by adjusting the sliding of the block on the pad body, thereby changing the support height of the insulating pad for the rail. Specifically, when the first support surface and the second support surface are closer to each other, the two sides of the bottom of the rail are respectively supported at higher positions of the first support surface and the second support surface. When the first support surface and the second support surface are farther away from each other, the two sides of the bottom of the rail are respectively supported at lower positions of the first support surface and the second support surface. Moreover, this one-sided adjustment method can further improve the stability and reliability of the insulating pad. At the same time, it is more convenient to adjust and the operation is simpler. The following is a detailed description of it through specific embodiments:

[0043] Reference Figures 1 to 11 As shown, an insulating pad block provided in this embodiment includes: a pad block body 1, which is made of insulating material and is arranged between the rail 3 and the cross beam 4; a fixed block 11, which is fixedly arranged on the top of the pad block body 1, wherein the fixed block 11 can be fixed to the top of the pad block body 1 by bonding, welding, screwing, riveting, etc., or the fixed block 11 and the pad block body 1 can be integrally formed; an adjusting block 12, which is slidably arranged on the top of the pad block body 1 in a direction perpendicular to the extension direction of the rail 3; a first supporting surface 111 is provided on the side of the fixed block 11 facing the adjusting block 12, and a second supporting surface 121 is provided on the side of the adjusting block 12 facing the fixed block 11, the first supporting surface 111 and the second supporting surface 121 are relatively arranged in a direction perpendicular to the extension direction of the rail 3, and are respectively used to support the bottom of the rail 3 on both sides along its extension direction; the first supporting surface 111 and the second supporting surface 121 gradually extend in the height direction from top to bottom in a direction close to each other.

[0044] The insulating spacer provided in the present embodiment changes the relative distance between the first supporting surface 111 and the second supporting surface 121 by sliding the adjustment block 12 on the spacer body 1, thereby changing the supporting height of the insulating spacer for the rail 3. Specifically, when the first supporting surface 111 and the second supporting surface 121 are closer to each other, the two sides of the bottom of the rail 3 are respectively supported at higher positions of the first supporting surface 111 and the second supporting surface 121; when the first supporting surface 111 and the second supporting surface 121 are further away from each other, the two sides of the bottom of the rail 3 are respectively supported at lower positions of the first supporting surface 111 and the second supporting surface 121; and this unilateral adjustment method can further improve the stability and reliability of the insulating spacer. At the same time, it is more convenient to adjust and the operation is simpler.

[0045] Specifically, the first supporting surface 111 and the second supporting surface 121 may be inclined structures or curved structures, as long as the height of the supporting point of the first supporting surface 111 and the second supporting surface 121 to the bottom of the rail 3 can be adjusted by adjusting the distance between them.

[0046] Among them, when the rail 3 is placed on the first support surface 111 and the second support surface 121, the squeezing force between the adjustment block 12 and the cushion block body 1 can be increased. The squeezing force can increase the friction between the adjustment block 12 and the cushion block body 1 in the direction perpendicular to the extension direction of the rail 3, so that the adjustment block 12 is not easy to slide and displace after being pressed again.

[0047] In some embodiments, the adjustment block 12 is slidably matched with the pad block body 1 through a slide rail structure, and the slide rail structure extends in a direction perpendicular to the extension direction of the rail 3; specifically, the slide rail structure may include a slider arranged at the bottom of the adjustment block 12 and extending in a direction perpendicular to the extension direction of the rail 3, and a slide groove arranged at the top of the pad block body 1 and extending in a direction perpendicular to the extension direction of the rail 3, wherein the slider and the slide groove are slidably matched in a direction perpendicular to the extension direction of the rail 3, and can limit each other in the extension direction of the rail 3, thereby ensuring that the adjustment block 12 can only slide in a direction perpendicular to the extension direction of the rail 3; avoiding the adjustment block 12 from sliding and displacing due to the movement of the rail 3 in its extension direction, causing position deviation.

[0048] In some embodiments, the insulating spacer block also includes a limiting structure, and the adjusting block 12 has a plurality of work positions in a direction perpendicular to the extension direction of the rail 3. When the adjusting block 12 slides to any work position, the limiting structure is used to limit the adjusting block 12 in a direction away from the fixed block 11; specifically, the limiting structure may include a plurality of slots arranged along the sliding direction of the adjusting block 12 and opened on the top of the spacer block body 1, each slot corresponding to a work position, and the limiting structure also includes an insert strip arranged on the adjusting block 12 and slidably plugged into the slot, so that when the adjusting block 12 moves to any work position, the insert strip can be inserted into the corresponding slot, thereby ensuring that the adjusting block 12 cannot continue to slide in a direction away from the fixed block 11, thereby achieving the locking of the adjusting block 12.

[0049] Continue to refer to Figures 3 to 5 As shown, the insulating spacer also includes a bolt 21 extending in a direction perpendicular to the extension direction of the rail 3, the bolt 21 forms a slide rail structure, the head of the bolt 21 is located on the side of the fixed block 11 away from the adjusting block 12, and cooperates with the fixed block 11 in the axial upper limit of the bolt 21, the threaded section of the bolt 21 is slidably plugged with the adjusting block 12, the end of the threaded section away from the fixed block 11 extends out of the adjusting block 12, and is threadedly connected with a nut 22, the nut 22 forms a limiting structure, it should be understood that the nut 22 can be rotated to the end of the threaded section away from the fixed block 11, or the nut 22 can be removed first, and then the adjustment When the segment block 12 moves to the set position, the nut 22 is tightened to fit the side of the adjusting block 12 facing away from the fixed block 11 to limit the position; specifically, the bolt 21 can be plug-fitted with the fixed block 11, or the threaded section of the bolt 21 can be threadedly fitted with the fixed block 11, thereby further improving the stability between the fixed block 11 and the bolt 21, and also facilitating subsequent parts maintenance work; when the adjusting block 12 is slidably fitted with the cushion block body 1 through the threaded section of the bolt 21, the bottom surface of the adjusting block 12 is slidably fitted with the top surface of the cushion block body 1, thereby ensuring that the adjusting block 12 will not rotate relative to the bolt 21.

[0050] In some embodiments, multiple bolts 21 are evenly arranged along the extension direction of the rail 3; such a setting can improve the connection reliability between the adjusting block 12 and the fixed block 11, realize redundant setting, and at the same time prevent the adjusting block 12 and a single bolt 21 from rotating relative to each other, further limit the adjusting block 12, and ensure the stability of the adjusting block 12 when sliding.

[0051] Continue to refer to Figure 3 and Figure 12 to Figure 14As shown, the insulating spacer also includes a pad 13, and the pad 13 is slidably matched with the first supporting surface 111 and the second supporting surface 121 on both sides along the extension direction of the rail 3, and the top of the pad 13 is used to support the rail 3, and an avoidance groove for avoiding the bolt 21 is opened on the pad 13; that is, the rail 3 may not be directly supported on the first supporting surface 111 and the second supporting surface 121, but the bottom of the rail 3 may be directly supported on the top of the pad 13 in contact with its surface, and the pad 13 is used to achieve buffering while increasing the stability of the rail 3 supported on the insulating spacer; the avoidance groove opened at the bottom of the pad 13 can prevent the pad 13 from interfering with the bolt 21 when the pad 13 is adjusted in the height direction.

[0052] Continue to refer to Fig.13 As shown, the avoidance groove is an oblong hole 131, and the threaded section of the bolt 21 is penetrated in the oblong hole 131. The oblong hole 131 extends a set distance in the height direction to achieve sliding cooperation between the bolt 21 and the pad 13 in the height direction; by designing the avoidance groove as an oblong hole 131, the pad 13 can form an integral structure with the fixing block 11, the adjusting block 12, the bolt 21 and the pad body 1, further improving the integrity and stability of the insulating pad, and avoiding the situation where a certain part is detached during use; at the same time, designing the avoidance groove as an oblong hole 131 can also limit the stroke of the pad 13 in the height direction; it should be noted that when the pad 13 moves to the lowest position, that is, when the threaded section of the bolt 21 is against the top of the oblong hole 131, the pad 13 can directly disperse the pressure from the rail 3 to the bolt 21, and then use the bolt 21 to transmit the pressure to the pad body 1, the overall force transmission structure is more stable and reliable, and the situation where the single part is damaged due to excessive stress of the part is reduced.

[0053] Continue to refer to Figure 3 and Figure 12 to Figure 14 As shown, the insulating spacer also includes a pad 13, and the pad 13 is provided with a first sliding surface 132 and a second sliding surface 133 on both sides along the extension direction of the rail 3, respectively. The slope of the first sliding surface 132 is the same as the slope of the first supporting surface 111, and the slope of the second sliding surface 133 is the same as the slope of the second supporting surface 121; the first sliding surface 132 and the second sliding surface 133 slide in cooperation with the first supporting surface 111 and the second supporting surface 121 correspondingly; at this time, the rail 3 is in surface contact with the pad 13, and the pad 13 is also in surface contact with the first supporting surface 111 and the second supporting surface 121, so that the load-bearing structure of the insulating spacer is more stable and reliable, avoiding excessive stress at a local position, resulting in irreversible damage at that position.

[0054] Furthermore, the first sliding surface 132 and the first supporting surface 111 can both be processed with anti-slip grooves to increase the friction between the two. Similarly, the second sliding surface 133 and the second supporting surface 121 can both be processed with anti-slip grooves to increase the friction between the two. In this way, the friction between the first sliding surface 132 and the first supporting surface 111 and the friction between the second sliding surface 133 and the second supporting surface 121 can be used to share part of the stress on the nut 22 or other limiting structures.

[0055] In a further embodiment, a baffle 14 is provided on the top of the fixed block 11 and the adjusting block 12, and the two baffles 14 extend along the extension direction of the rail 3; through the setting of the baffle 14, the rail 3 can be limited and positioned. It should be noted that baffles 14 can also be provided on both sides of the bottom of the pad body 1 along the extension direction of the cross-lifting beam 4, so as to limit and position the cross-lifting beam 4, thereby preventing the pad body 1 from slipping off the rail 3 and the cross-lifting beam 4, thereby improving the stability and reliability of the insulating pad; a limiting groove for limiting and positioning the rail 3 or the cross-lifting beam 4 is formed between the two baffles 14, thereby enriching the function of the insulating pad and improving the novelty of the insulating pad. The structural design of the insulating pad is novel, further enhancing the insulation and stability of the rail 3 and the cross-lifting beam 4, and providing better protection for the track circuit, which can significantly reduce the maintenance intensity and frequency of construction personnel.

[0056] Continue to refer to Figure 3 , Figure 6 and Fig. 9 As shown, the two baffles 14 are provided with a guide slope 141 on one side facing each other, and the two guide slopes 141 together form an open structure. The slopes of the two guide slopes 141 are the same, so that they can play a certain guiding role and are more convenient for positioning the pad 13 or the rail 3. The two baffles 14 located at the bottom of the pad body 1 can also form an open structure through the guide slopes 141, so as to facilitate positioning the cross beam 4; the first support surface 111 and the second support surface 121 are inclined surface structures, and the slopes of the first support surface 111 and the second support surface 121 are the same, and the slopes of the first support surface 111 and the second support surface 121 are both smaller than the slopes of the guide slopes 141; that is, sliding upward on both sides of the pad 13 When it reaches the connection between the first support surface 111 and the guide slope 141 and the connection between the second support surface 121 and the guide slope 141, a jamming phenomenon will occur, which reduces the probability of the pad 13 slipping off the first support surface 111 and the second support surface 121. Since the slopes of the first support surface 111 and the second support surface 121 are both smaller than the slope of the guide slope 141, it should be understood that the difficulty of the pad 13 sliding upward along the first support surface 111 and the second support surface 121 will be less than the difficulty of the pad 13 sliding upward along the two guide slopes 141, thereby further reducing the probability of the pad 13 slipping off the first support surface 111 and the second support surface 121.
