Description

Technical Field

[0001] This utility model relates to the field of contact wire positioning technology in the overhead contact system of electrified tunnels, and in particular to a horizontal suspension positioning structure in tunnels. Background Technology

[0002] In tunnel contact network systems, a duckbill positioning structure is designed (such as...). Figure 1 As shown, the contact wire is positioned using a duckbill positioning structure 40, which includes a positioning base 401 fixed to the inner wall 10 of the tunnel, a positioning toothed seat 402 fixed to the positioning base 401, and a positioning collar 403. During the installation of the contact wire, one end of the positioning collar 403 is connected to one end of the positioning tube 405 through an insulator structure 404, and the other end can be selectively fitted into any tooth groove of the positioning toothed seat 402. At the same time, the other end of the positioning tube 405 is connected to a long support (not shown) used to fix the contact wire. Obviously, the teeth of the positioning toothed seat 402 face the inner wall 10 of the tunnel. Therefore, when fitting the positioning collar 403 into the tooth groove of the positioning toothed seat 402, the positioning collar 403 must first be pulled in the direction towards the inner wall 10 of the tunnel until the positioning collar 403 comes out of the tooth groove or is completely fitted into the toothed end of the positioning toothed seat 402. Then, the positioning collar 403 is moved to the appropriate tooth groove and locked in place. Therefore, the traditional horn duckbill positioning structure 40, after the positioning collar 403 moves towards the inner wall of the tunnel 10 and then moves away from the inner wall of the tunnel 10 to be inserted into the tooth groove, still results in low positioning accuracy. Moreover, during use, there is a risk that the positioning collar 403 may fall off the tooth opening of the tooth groove, causing an accident, which poses a significant safety hazard. Utility Model Content

[0011] In one embodiment, the hanging rod member further includes a limiting member. The limiting member is detachably mounted on the bolt and located outside the second sub-hole.

[0012] In one embodiment, one end of the bolt located outside the second sub-hole is provided with a limiting hole. The limiting member is a limiting rod. The limiting rod is inserted into the limiting hole and cooperates with the limiting hole in a small gap, and both ends of the limiting rod respectively extend out of the two end openings of the limiting hole.

[0013] In one embodiment, one end of the fixed base is provided with a mounting hole. The positioning seat includes a first positioning plate, a second positioning plate, and a fastening connecting member. One end of the first positioning plate is provided with a first connecting hole, and the other end is provided with a plurality of first sub-holes spaced apart in a straight line direction. One end of the second positioning plate is provided with a second connecting hole corresponding to the first connecting hole, and the other end is provided with a plurality of second sub-holes spaced apart in a straight line direction. The first positioning plate and the second positioning plate are respectively clamped on both sides of the fixed base provided with the mounting hole at one end, and the first connecting hole, the second connecting hole, and the mounting hole are aligned in the spacing direction of the first positioning plate and the second positioning plate. One end of the fastening connecting member is inserted into the first connecting hole, and the other end is inserted through the mounting hole and connected to the second connecting hole.

[0014] In one embodiment, the mounting hole, the first connecting hole, the second connecting hole, and the fastening connecting member are one-to-one corresponding. One end of each fastening connecting member is inserted into the corresponding first connecting hole, and the other end is inserted through the corresponding mounting hole and connected to the corresponding second connecting hole.

[0018] The tunnel inner horizontal suspension positioning structure can avoid the risk of accidents caused by the disengagement of the positioning sleeve ring from the positioning seat during use when the horizontal suspension position of the contact wire in the tunnel is positioned, because the positioning sleeve ring is directly sleeved on the middle position of the hanging rod member through the hanging hole, and the two ends of the hanging rod member are connected with the first sub-hole and the second sub-hole, respectively. In addition, when the horizontal suspension position of the contact wire in the tunnel needs to be adjusted, the hanging rod member only needs to be removed from the current adjusting hole, and the end of the positioning sleeve ring provided with the positioning hanging hole is moved to the adjusting hole corresponding to the position of the contact wire after the horizontal suspension position is adjusted, and then the hanging rod member is arranged and fastened, so that the positioning sleeve ring does not need to be pulled towards the inner wall of the tunnel and then retracted away from the inner wall of the tunnel during the whole adjustment and positioning process, which greatly improves the positioning accuracy. Therefore, the tunnel inner horizontal suspension positioning structure not only reduces the safety risk during use, but also improves the positioning accuracy of the contact wire.

[0030] Figure 2 The structure of the tunnel horizontal suspension positioning structure in the embodiment of the utility model is shown. For the convenience of illustration, the drawings only show the structure related to the embodiment of the utility model.

[0031] Please refer to Figure 2 The tunnel horizontal suspension positioning structure 100 in the preferred embodiment of the utility model comprises a fixed base 110, a positioning seat 120, a positioning sleeve ring 130 and a hanging rod piece 140.

[0032] Please refer to Figure 3 and Figure 4 The fixed base 110 is used for fixing at the preset position of the tunnel inner wall 10. In this way, in the actual use process, the fixed base 110 is fixed at the preset position of the tunnel inner wall 10, so that the fixed installation of the tunnel horizontal suspension positioning structure 100 in the tunnel can be realized.

[0033] The positioning seat 120 is detachably installed on the fixed base 110. The positioning seat 120 is a hollow double-layer structure, and a plurality of adjusting holes 121 are spaced apart in a straight line direction. Each adjusting hole 121 penetrates the double-layer structure and comprises a first sub-hole 1211 and a second sub-hole 1212 aligned with the first sub-hole 1211. Among them, the first sub-hole 1211 and the second sub-hole 1212 in each adjusting hole 121 are respectively located on the two cavity walls of the double-layer structure, and are aligned in a direction perpendicular to the spacing direction of the plurality of adjusting holes 121.

[0034] One end of the positioning collar 130 has a hanging hole (not shown in the figure), and the other end is used to be movably connected with the positioning pipe 30 through the insulator structure 20. The end of the positioning collar 130 with the hanging hole extends into the double-layer structure, and the hanging hole is optionally aligned with any one of the adjusting holes 121. Specifically, the spacing direction of the plurality of adjusting holes 121 is perpendicular or intersected with the stress direction of the positioning collar 130. The stress direction of the positioning collar 130 is consistent with the longitudinal direction of the positioning pipe 30. The end of the positioning collar 130 provided with the hanging hole can be a plate-shaped or block-shaped structure, and the hanging hole is a through hole formed on the positioning collar 130 at this time. The end of the positioning collar 130 provided with the hanging hole can also be a ring-shaped structure surrounded by a rod, and the hanging hole is an inner hole surrounded by the rod at this time. The end of the positioning collar 130 provided with the hanging hole can also be other structures, for example, the positioning collar 130 is a U-shaped structure, and only the end of the opening end of the U-shaped structure is movably connected with the insulator structure 20, so that the positioning collar 130 and the end of the opening end of the insulator structure 20 together surround a closed "hanging hole".

[0035] In addition, it should be pointed out that the purpose of defining the positioning collar 130 as a collar is only to correspond to the positioning collar 130 in the background art, indicating that the two structures are the same part, facilitating understanding of the technical solution, and the specific shape of the positioning collar 130 is not limited here, as long as the end of the positioning collar 130 has a hanging hole and can extend into the double-layer structure, and the other end can be movably connected with the positioning pipe 30 through the insulator structure 20.

[0036] One end of the hanging rod 140 is optionally arranged in any one of the first sub-holes 1211, and the other end passes through the hanging hole and is connected with the corresponding second sub-hole 1212. In this way, the two ends of the hanging rod 140 are arranged in the first sub-hole 1211 and the second sub-hole 1212 in any one of the adjusting holes 121 respectively, and the positioning collar 130 is sleeved on the middle position of the hanging rod 140 through the hanging hole, so as to realize the positioning of the positioning collar 130 on the positioning seat 120.

[0037] When the horizontal suspension position of the contact wire in the tunnel needs to be positioned, the fixed base 110 is first fixed at the preset position of the tunnel inner wall 10, and then the end of the positioning collar 130 away from the hanging hole is movably connected with the positioning pipe 30 through the insulator structure 20, and the other end of the positioning pipe 30 is connected with the long support for fixing the contact wire. Finally, the positioning collar 130 is pulled in the direction towards the tunnel inner wall 10 until the end of the positioning collar 130 provided with the hanging hole extends into the double-layer structure of the positioning seat 120, and the hanging hole is aligned with one of the adjusting holes 121. At this time, the hanging rod 140 is sequentially arranged in the first sub-hole 1211, the hanging hole and the second sub-hole 1212 and is fastened and connected.

[0038] When the horizontal suspension position of the contact wire in the tunnel needs to be adjusted, the hanging rod member 140 is only needed to be disassembled from the current adjusting hole 121, the positioning sleeve ring 130 is moved to the adjusting hole 121 corresponding to the horizontal suspension position of the contact wire after the adjustment, and then the hanging rod member 140 is sequentially inserted into the first sub-hole 1211, the hanging hole and the second sub-hole 1212, and the hanging rod member 140 is detachably connected with the positioning seat 120.

[0039] The above-mentioned horizontal suspension positioning structure 100 in the tunnel can avoid the risk of accidents caused by the positioning sleeve ring 130 being separated from the positioning seat 120 during use when positioning the horizontal suspension position of the contact wire in the tunnel, because the positioning sleeve ring 130 is directly sleeved on the middle position of the hanging rod member 140 through the hanging hole, and the two ends of the hanging rod member 140 are connected with the first sub-hole 1211 and the second sub-hole 1212 respectively. In addition, when the horizontal suspension position of the contact wire in the tunnel needs to be adjusted, the hanging rod member 140 is only needed to be disassembled from the current adjusting hole 121, and the end of the positioning sleeve ring 130 provided with the positioning hanging hole is moved to the adjusting hole 121 corresponding to the horizontal suspension position of the contact wire after the adjustment, and then the hanging rod member 140 is inserted and fastened, so that the positioning sleeve ring 130 does not need to be pulled towards the tunnel inner wall 10 and then retracted away from the tunnel inner wall 10 during the whole adjustment and positioning process, which greatly improves the positioning accuracy.

[0040] Therefore, the above-mentioned horizontal suspension positioning structure 100 in the tunnel not only reduces the safety risk during use, but also improves the positioning accuracy of the contact wire.

[0041] In one embodiment, the hanging rod member 140 includes a bolt 141 and a nut 142. The first sub-hole 1211 and the second sub-hole 1212 are both light holes. One end of the bolt 141 is inserted into the first sub-hole 1211, and the other end is sequentially inserted through the hanging hole and the second sub-hole 1212 and screwed with the nut 142. In this way, when the positioning sleeve ring 130 needs to be positioned at a certain adjusting hole 121, only the end of the bolt 141 with the nut needs to be inserted into the first sub-hole 1211, and the other end is sequentially inserted through the hanging hole and the second sub-hole 1212 and screwed with the nut 142, at this time the end surface of the nut 142 abuts against the outer edge of the second sub-hole 1212, so that the positioning of the positioning sleeve ring 130 on the positioning seat 120 is realized, and therefore the positioning and adjustment of the horizontal suspension position of the contact wire in the tunnel only need the worker to turn the bolt 141 and / or the nut 142, so that the hanging rod member 140 can be disassembled and assembled conveniently and quickly, and the fastening between the hanging rod member 140 and the positioning seat 120 is reliable.

[0042] In another embodiment, the hanging rod 140 is a bolt 141, with a first sub-hole 1211 being a smooth hole and a second sub-hole 1212 being a threaded hole. One end of the bolt 141 with a nut passes through the first sub-hole 1211, and the other end passes through the hanging hole and is screwed into the second sub-hole 1212. Thus, when the positioning collar 130 needs to be positioned at a certain adjustment hole 121, it is only necessary to pass one end of the bolt 141 with a nut through the first sub-hole 1211, and the other end through the hanging hole and screwed into the second sub-hole 1212. This achieves the positioning of the positioning collar 130 on the positioning seat 120. Therefore, the positioning and adjustment of the contact wire's horizontal suspension position in the tunnel can be easily and quickly accomplished by simply turning the bolt 141.

[0043] Furthermore, in some embodiments, the hanging rod 140 also includes a limiting member 143. The limiting member 143 is detachably mounted on the bolt 141 and is located outside the second sub-hole 1212.

[0044] Thus, the limiting member 143 is used to limit the axial position of the bolt 141 on the positioning seat 120, so as to reduce the probability that the bolt 141 will come out of the adjustment hole 121 after long-term use, and further reduce the safety risks of the horizontal suspension positioning structure 100 in the tunnel during use.

[0045] Furthermore, in some embodiments, a limiting hole (not shown) is formed at one end of the bolt 141 located outside the second sub-hole 1212. The limiting member 143 is a limiting rod. The limiting rod passes through the limiting hole and fits with the limiting hole with a small clearance, and its two ends extend out of the openings at both ends of the limiting hole. The limiting rod can be a rod-shaped structure such as a pin or a cotter pin. To reduce the difficulty of assembling and disassembling the limiting rod in the limiting hole, specifically, the limiting rod is a cotter pin.

[0046] It should be noted that a micro-clearance fit typically refers to an h7 / h6 fit, specifically meaning that the clearance between the hole and the shaft is very small, even close to zero, but a certain amount of clearance still exists. This fit allows for some relative movement of the shaft within the hole, but due to the extremely small clearance, this movement is strictly limited. Therefore, a micro-clearance fit between the limiting rod and the limiting hole ensures that the limiting rod is not easily slipped out of the limiting hole and that workers do not have to exert too much effort when installing or removing the limiting rod. This not only further improves the safety of the horizontal suspension positioning structure 100 in the tunnel but also reduces the difficulty of adjusting the horizontal suspension position of the contact wire.

[0047] Of course, in other embodiments, the limiting member 143 can also be a locking nut 142 or other structures.

[0048] Please refer to the following: Figure 5In some embodiments, the fixed base 110 has a mounting hole 111 at one end. The positioning base 120 includes a first positioning plate 122, a second positioning plate 123, and a fastening connector 124. The first positioning plate 122 has a first connecting hole (not shown) at one end, and a plurality of first sub-holes 1211 spaced apart along a straight line at the other end. The second positioning plate 123 has a second connecting hole (not shown) corresponding to the first connecting hole at one end, and a plurality of second sub-holes 1212 spaced apart along a straight line at the other end. The first positioning plate 122 and the second positioning plate 123 are respectively clamped on both sides of the fixed base 110 at the end with the mounting hole 111, and the first connecting hole, the second connecting hole, and the mounting hole 111 are aligned in the spacing direction of the first positioning plate 122 and the second positioning plate 123. One end of the fastening connector 124 passes through the first connecting hole, and the other end passes through the mounting hole 111 and connects to the second connecting hole. Thus, the first positioning plate 122 and the second positioning plate 123 are spaced apart axially in the mounting hole 111 to form a hollow double-layer structure. When the positioning collar 130 is installed on the positioning seat 120, the end of the positioning collar 130 with the hanging hole extends between the first positioning plate 122 and the second positioning plate 123.

[0049] Thus, when the positioning seat 120 needs to be installed on the fixed base 110, it is only necessary to clamp the first positioning plate 122 and the second positioning plate 123 from two directions at the end of the fixed base 110 with the mounting hole 111, and then clamp the fixed base 110 between the first positioning plate 122 and the second positioning plate 123 by sequentially passing the fastening connector 124 through the first connecting hole, the mounting hole 111 and the second mounting hole 111, so as to realize the installation of the positioning seat 120 on the fixed base 110. Moreover, dividing the positioning seat 120 into three parts, namely the first positioning plate 122, the second positioning plate 123 and the fastening connector 124, is beneficial to reducing the processing difficulty and processing cost of the positioning seat 120.

[0050] Furthermore, in some embodiments, there are multiple mounting holes 111, first connecting holes, second connecting holes, and fastening connectors 124, each corresponding to a specific type. One end of each fastening connector 124 passes through the corresponding first connecting hole, and the other end passes through the corresponding mounting hole 111 and connects to the corresponding second connecting hole. In this way, multiple connections are achieved between the first positioning plate 122 and the positioning base, and between the second positioning plate 123 and the positioning base, thereby effectively improving the connection strength and structural stability between the first positioning plate 122 and the positioning base, and between the second positioning plate 123 and the positioning base.

[0051] To simplify the installation process, reduce the processing cost of the horizontal suspension positioning structure 100 in the tunnel, and ensure the stability of the connection between the positioning seat 120 and the fixed base 110, in this embodiment, the mounting hole 111, the first connecting hole, the second connecting hole, and the fastening connector 124 are all two in a one-to-one correspondence.

[0052] Furthermore, in some embodiments, there are two hanging rods 140. One hanging rod 140 has one end inserted through the first sub-hole 1211 furthest from the first connecting hole, and the other end connected to the second sub-hole 1212 furthest from the second connecting hole. The other hanging rod 140 may selectively be inserted through any of the remaining first sub-holes 1211, and the other end connected to the second sub-hole 1212 aligned with the first sub-hole 1211. Either of the two hanging rods 140 may pass through a hanging hole.

[0053] Of course, in actual use, unless the positioning collar 130 must be moved to the outermost adjustment hole 121 to adjust the horizontal suspension position of the contact line, the positioning collar 130 is more often fitted on the hanging rod 140 near the positioning base.

[0054] Thus, in the spaced directions of the multiple adjustment holes 121, except for the hanging rod 140 used to hold the positioning collar 130, both ends of the first positioning plate 122 and the second positioning plate 123 are fixed, thereby improving the structural stability of the positioning seat 120 during use.

[0055] Furthermore, in some embodiments, the horizontal suspension positioning structure 100 inside the tunnel also includes two adjusting shims 150. Both adjusting shims 150 are sleeved on the fastening connector 124 and respectively clamped between the first positioning plate 122 and the fixed base 110, and between the second positioning plate 123 and the fixed base 110. The thickness of the adjusting shims 150 is adjustable.

[0056] Specifically, the thickness of the adjusting shim 150 can be adjusted in two ways: one is by replacing shims of different thicknesses, and the other is that each adjusting shim 150 consists of at least one sub-shim, and the adjustment can be achieved by increasing or decreasing the number of sub-shims.

[0057] Therefore, by adjusting the thickness of the shim 150, the gap between the first positioning plate 122 and the second positioning plate 123 can be adjusted, so that the positioning seat 120 can meet the use of positioning collars 130 of different sizes, thereby improving the applicability of the horizontal suspension positioning structure 100 in the tunnel and helping to reduce the installation cost of the contact wire in the tunnel.

[0058] Please refer to the following: Figure 6In some embodiments, the fixed base 110 includes a corner bracket 112, a support plate 113, and an anchor bolt (not shown). Two sides of the support plate 113 are fixedly connected to two inner sides of the corner bracket 112. An elongated through-hole 1121 is formed on one inner side of the corner bracket 112. One end of the anchor bolt passes through the elongated through-hole 1121, and the other end is used to fix it at a preset position on the tunnel inner wall 10. The end of the support plate 113 away from the corner bracket is detachably connected to the positioning seat 120. Specifically, one inner side of the corner bracket 112 without the elongated through-hole 1121 faces the positioning collar 130. The corner bracket 112 is fixed to the preset position on the tunnel inner wall 10 by the anchor bolt, thereby fixing the fixed base 110 to the tunnel inner wall 10.

[0059] In practical applications, the positioning collar 130, insulator structure 20, positioning tube 30, long support and other structures will exert a downward pulling force on the positioning seat 120 under the action of gravity. This pulling force is transmitted to the support plate 113 through the positioning seat 120, and then to the inner side of the corner bracket seat 112 where the elongated through hole 1121 is not formed. The inner side of the corner bracket seat 112 where the elongated through hole 1121 is not formed plays a bearing role, so as to reduce the force on the anchor bolt, improve the fixing reliability of the fixed base 110 on the tunnel inner wall 10, and thus further reduce the safety of the use of the above-mentioned horizontal suspension positioning structure 100 in the tunnel.

[0060] Specifically, when the fixed base 110 has a mounting hole 111, the support plate 113 has a mounting hole 111 at the end away from the corner bracket 112.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
