Abstract
Description
Leaky cable hoist Technical Field
[0001] The present invention relates to the technical field of cable laying and installation equipment, and in particular to a leaky cable hanger. Background Art
[0002] With the ongoing development of new high-speed trains and the construction of lines designed for higher-speed operation, ensuring the safety, stability, and reliability of train-to-ground wireless communication systems is essential. Leaky cables are the primary medium for transmitting and receiving wireless communication signals within tunnels, and the cable hangers, the primary fixtures supporting them, must be able to withstand the high wind pressure and environmental degradation caused by high-speed trains.
[0003] The main types of existing high-speed railway leaky cable hoists are the inward-clicking type, which is achieved by engaging the cover plate to the inside of the base, but this engagement method is prone to natural loosening after the auxiliary pin fails; pin locking, this method requires two or more sets of pins in addition to the base and cover plate, which need to be installed on-site on the high-speed railway line. The additional components make the overall construction more complicated and easy to fall onto the track area; offset type, that is, there is a certain offset angle between the injection-molded parts of the hoist and the metal support parts, exposing the metal fixing bolts. This method has certain advantages when disassembling the hoist, but there is a risk that the metal fixing bolts are easy to fall off into the track area during normal use; bottom anchor fixation, but this method only performs bottom locking on the anchor bolts, and does not form multiple locking, which can easily lead to unstable fixation of the leaky cable hoist.
[0004] The existing high-speed railway leaky cable spreaders have the following problems: First, there are safety hazards. For example, the inward-clicking and offset spreaders, although they are conducive to simplifying installation or disassembly, they bring greater safety hazards; second, the construction requirements are high. For example, the additional pin fixing structure requires carrying multiple components. The pin assembly can only be carried out after the spreader is inserted into the leaky cable on site, which greatly increases the construction time and difficulty. At the same time, the installation process of the expanded bottom anchor bolts has high requirements. The structure of the anchor bolts is simple and there is only a one-time locking structure. If the construction is not standardized, it is easy to cause the risk of falling off; third, the maintenance requirements are high. If the spreader is damaged, it can only be replaced as a whole. It is impossible to temporarily inspect and fix the spreader at the fault point, which increases the difficulty of subsequent maintenance. At the same time, the spreader has no conspicuous open and closed status identification mark and is fixed at a high position above the head. If the spreader falls off, it can only be discovered by approaching, looking up, and checking one by one. It is impossible to use a simple method to repair it.
[0005] Therefore, how to reduce the construction and maintenance requirements of the leaky cable spreader while ensuring its safety is a technical problem faced by those skilled in the art. Summary of the Invention

DETAILED DESCRIPTION
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] As shown in Figures 1 to 7, the present invention provides a leaky cable hanger, comprising an anchoring mechanism 1 and a cable locking mechanism 2. One end of the anchoring mechanism 1 is connected to a concrete foundation structure, and the end of the anchoring mechanism 1 extending out of the concrete foundation structure is connected to the cable locking mechanism 2. As shown in Figure 2, the anchoring mechanism 1 comprises: a connecting screw 11; a locking member 12, the locking member 12 comprising a connecting portion 121, a supporting portion 122, and an anchoring portion 123 connected in sequence, the locking member 12 being connected to the distal end of the connecting screw 11 via the connecting portion 121, the supporting portion 122 being located at the distal end of the connecting portion 121, the anchoring portion 123 being located at the distal end of the supporting portion 122, and a first anchoring hole being formed in the anchoring portion 123; and a tapered pin 13 being provided at the distal end of the locking member 12. The tapered pin 13 can be embedded in the first anchoring hole and can cause the anchoring portion 123 to expand radially outward, so that the anchoring portion 123 is fixed in the concrete foundation structure. Specifically, when the anchoring portion 123 of the locking member 12 is driven into the concrete foundation structure, the tapered pin 13 can cause the anchoring portion 123 to expand radially outward, so that the anchoring portion 123 is fixed in the concrete foundation structure, forming a first layer of locking structure. When an external force pulls the locking member 12 so that it tends to move outward, the expansion clamp ring 14 can expand radially outward under the action of the supporting portion 122, further increasing the friction between the anchoring portion 123 and the concrete foundation structure, forming a second layer of locking structure. The double-layer locking enables the connecting screw 11 to be firmly set on the concrete foundation structure.
[0037] Among them, as shown in Figures 3 to 7, the cable locking mechanism 2 includes: at least one cable supporting bracket 21, on which a circumferential limit block 211 and an axial limit groove 212 are formed. Optionally, as shown in Figure 7, a groove is provided on the circumferential limit block 211, which forms the axial limit groove 212; at least one cable locking cover plate 22, on which an axial limit portion 221 corresponding to the axial limit groove 212 is formed, and a circumferential limit hook portion 222 corresponding to the circumferential limit block 211 is formed. The cable locking cover plate 22 can be pivotally provided on the cable supporting bracket 21, and an accommodating space for installing a leaking cable is formed between the cable supporting bracket 21 and the cable locking cover plate 22. When the cable cover plate 22 is pivotally mounted on the cable support bracket 21, the circumferential limiting hook 222 can elastically contract radially inward under the pressure of the circumferential limiting block 211, and can rebound to the lower end surface of the circumferential limiting block 211 and hook the circumferential limiting block 211, so that the cable cover plate 22 and the cable support bracket 21 are locked. When the circumferential limiting hook 222 hooks the circumferential limiting block 211, the axial limiting portion 221 is correspondingly engaged in the axial limiting groove 212, so that the cable cover plate 22 is axially limited by the cable support bracket 21. As shown in FIG4 , after the axial limiting portion 221 and the axial limiting groove 212 are engaged, a radially outward gap is left, and the gap forms a reserved disassembly hole 20. As shown in FIG7 , the cable support bracket 21 is further provided with a leaky cable back reinforcement limiting groove 210 for accommodating the leaky cable raised back reinforcement marking line. Specifically, the circumferential limit block 211 and the axial limit groove 212 are integrally formed on the cable support bracket 21, and the axial limit portion 221 and the circumferential limit hook portion 222 are integrally formed on the cable lock cover plate 22. In this embodiment, there are two cable support brackets 21, which are arranged opposite each other, and there are two cable lock cover plates 22, each connected to one of the two cable support brackets 21.
[0038] To further illustrate the leaky cable hanger of the embodiment of the present invention, the specific structure and connection relationship thereof are further described below, wherein:
[0039] According to one embodiment of the present invention, as shown in Figure 2, in order to facilitate the tapered pin 13 to be embedded in the first anchor hole and maintain the stability of the first layer of locking structure, the diameter of the tapered pin 13 is gradually expanded from the proximal end to the distal end, and the maximum value of the diameter of the tapered pin 13 is greater than the diameter of the first anchor hole.
[0040] Furthermore, the diameter of the top support portion 122 is gradually expanded from the proximal end to the distal end; the anchoring mechanism 1 also has an expansion clamp ring 14 mounted on the connecting portion 121, and a second anchoring hole is formed in the expansion clamp ring 14. The maximum diameter of the top support portion 122 is greater than the diameter of the second anchoring hole. The top support portion 122 can be embedded in the second anchoring hole and cause the expansion clamp ring 14 to expand radially outward, so that when the anchoring mechanism 1 is pulled by external force and the locking member 12 tends to move outward, the second layer of locking structure is formed and maintained to be stable.
[0041] According to one embodiment of the present invention, as shown in FIG7 , the cable locking mechanism 2 further comprises a support base 23 having a mounting hole 231 formed in the middle thereof. The anchoring mechanism 1 is connected to the support base 23 via the mounting hole 231. The support base 23 is formed with at least one supporting rib 232, and the cable support bracket 21 is connected to the support base 23 via the supporting rib 232. Furthermore, the support base 23 has a plurality of binding holes 233 formed around the mounting hole 231. Specifically, the mounting hole 231 is located between two cable support brackets 21, and the mounting hole 231 is located at the center of the support base 23. The plurality of binding holes 233 are evenly distributed around the mounting hole 231. When there are two or more cable support brackets 21, the binding holes 233 are located between two adjacent cable support brackets 21. This facilitates bundling and reinforcement of the leaky cable by passing binding wire through the binding holes 233. In this embodiment, the support base plate 23 and the cable support bracket 21 are integrally formed, and an insertion groove 234 is further formed on the upper end surface of the support base plate 23 so that the cable locking mechanism 2 can be used to install other types of cables, thereby improving the versatility of the cable locking mechanism 2.
[0042] According to one embodiment of the present invention, as shown in FIG1 , the anchoring mechanism 1 further comprises a connecting nut 15 and a fixing bolt 16. The connecting nut 15 is threadedly connected to the connecting screw 11, and the fixing bolt 16 passes through the mounting hole 231 and is threadedly connected to the connecting nut 15, thereby fixing the cable locking mechanism 2 to the anchoring mechanism 1. Specifically, the anchoring mechanism 1 is threadedly connected to the supporting base plate 23 through the mounting hole 231, so that the cable locking mechanism 2 and the anchoring mechanism 1 are firmly fixed together.
[0043] According to one embodiment of the present invention, as shown in Figure 7, an axial limit groove 212 is formed in the middle of the circumferential limit block 211, and the cable support bracket 21 extends radially inward to form two positioning parts 213 arranged opposite to each other in the axial direction, and the circumferential limit block 211 is located between the two positioning parts 213, and a hook embedding groove 214 is formed between the two positioning parts 213; in the process of the cable lock cover plate 22 being pivotally provided on the cable support bracket 21, the circumferential limit hook 222 can elastically shrink radially inward under the extrusion of the circumferential limit block 211, and can rebound to the lower end surface of the circumferential limit block 211 through the hook embedding groove 214 and hook the circumferential limit block 211, so that the cable lock cover plate 22 and the cable support bracket 21 are locked, and the hook embedding groove 214 is used to accommodate the circumferential limit hook 222 that elastically shrinks radially inward.
[0044] Furthermore, as shown in Figure 7, the circumferential limit block 211 extends to form an auxiliary locking portion 215 protruding between the two positioning portions 213, and the auxiliary locking portion 215 is provided with an auxiliary locking embedding groove 2151. The cable cover plate 22 extends radially outward to form an auxiliary locking elastic hook 223 corresponding to the auxiliary locking embedding groove 2151, and the axial limiting portion 221 is located between the auxiliary locking elastic hook 223 and the circumferential limiting hook portion 222, and extends circumferentially; when the circumferential limiting hook portion 222 hooks the circumferential limit block 211, the auxiliary locking elastic hook 223 can rebound and be embedded in the auxiliary locking embedding groove 2151 to assist in locking the cable cover plate 22 and the cable supporting bracket 21; and when the circumferential limiting hook portion 222 hooks the circumferential limit block 211, the axial limiting portion 221 is correspondingly embedded in the axial limiting groove 212, so that the cable cover plate 22 is axially limited by the cable supporting bracket 21. Specifically, in the process of the cable cover 22 being pivotally arranged on the cable supporting bracket 21, the circumferential limit hook 222 can elastically shrink radially inward under the extrusion of the circumferential limit block 211, and the auxiliary lock elastic hook 223 can elastically shrink radially inward under the extrusion of the auxiliary lock portion 215. When the circumferential limit hook 222 reaches the position of the hook embedding groove 214, the auxiliary lock elastic hook 223 reaches the position of the auxiliary lock embedding groove 2151. When the circumferential limit hook 222 hooks the circumferential limit block 211, the auxiliary lock elastic hook 223 can rebound and be embedded in the auxiliary lock embedding groove 2151 and hook the auxiliary lock portion 215, so that the auxiliary lock embedding groove 2151 can assist in limiting the relative position between the cable cover 22 and the cable supporting bracket 21 through the auxiliary lock elastic hook 223. As shown in Figures 3 and 5 , the auxiliary lock elastic hook 223 can be one or multiple, and correspondingly, the auxiliary lock embedding groove 2151 can also be one or multiple, but the present invention does not limit this. In this embodiment, the auxiliary lock portion 215 is integrally formed on the circumferential limit block 211, and the auxiliary lock elastic hook 223 is integrally formed on the lock cable cover plate 22.
[0045] According to one embodiment of the present invention, as shown in FIG6 , the cable lock cover 22 extends radially inward to form two elastic pressing pieces 224 disposed opposite each other. When the leaky cable is disposed within the accommodation space, the leaky cable is pressed against the cable support bracket 21 by the two elastic pressing pieces 224. This further strengthens the connection between the cable lock mechanism 2 and the leaky cable.
[0046] According to one embodiment of the present invention, the cable lock cover plate 22 is made of a nylon material containing a polyolefin thermoplastic elastomer (POE) material and an environmentally friendly melamine flame retardant. The addition of the POE material effectively improves the toughness of the cable lock cover plate 22 and reduces its hygroscopicity. When the cable lock mechanism 2 encounters high or low temperatures, the cable lock cover plate 22 will not become brittle due to water loss, thereby ensuring the stability of the leaky cable installation. Furthermore, the addition of the environmentally friendly melamine flame retardant to the cable lock cover plate 22 also ensures excellent heat resistance, ensuring that the finished sling meets the flame retardant and fire resistance requirements of automatically extinguishing within 10 seconds after ignition and removal of the open flame.
[0047] Furthermore, the mass fraction of the polyolefin thermoplastic elastomer material is between 5% and 15% (e.g., 8%, 10%, 12%, etc.). Furthermore, the nylon material used in the cable lock cover 2212 can produce a fluorescent color after extrusion molding. Under the long-term influence of train piston wind, if the closing state of individual spreaders is abnormal, the individual differences in the row of reflective markings illuminated by the lights can more easily identify the specific location of the spreader, facilitating maintenance.
[0048] Based on the above structural description, the leaky cable hanger of the embodiment of the present invention has the following beneficial effects:
[0049] The cable locking mechanism 2 of the leaky cable hoist provided in the embodiment of the present invention includes a support base plate 23, a cable support bracket 21, and a cable locking cover plate 22, wherein the support base plate 23 and the cable support bracket 21 are integrally formed, and the cable locking cover plate 22 is rotatably connected to the cable support bracket 21, so that the cable locking mechanism 2 is interconnected as a whole, effectively reducing the number of parts, thereby reducing the impact of parts falling off on the stability of the leaky cable fixation and the safety of the railway road; at the same time, the rotational connection and cover buckle locking structure between the cable locking cover plate 22 and the cable support bracket 21 can also greatly improve the speed and efficiency of the leaky cable installation; in addition, the cable locking mechanism 2 can be completely disassembled by special tools, which is convenient for the secondary use of the cable locking mechanism 2. Furthermore, the anchoring mechanism 1 of the leaky cable hoist provided in the embodiment of the present invention has a double locking function, which can enable the cable locking mechanism 2 to be stably anchored and installed in the concrete foundation structure, thereby improving the overall installation stability of the leaky cable hoist.
[0050] The installation steps of the leaky cable hanger provided by the present invention are as follows:
[0051] Step S1: First, a hole is drilled in the tunnel wall, and then the anchoring mechanism 1 is implanted. The cable locking mechanism 2 is connected to the anchoring mechanism 1, and the cable locking mechanism 2 is adjusted to a position where the cable locking cover 22 can be opened and closed with the buckled end facing upwards.
[0052] Step S2: Flip the cable lock cover 22 to the side of the supporting base plate 23 and keep it open. Adjust the working radiation angle of the leaky cable and align the protruding back rib mark line of the leaky cable with the back rib limiting groove 210 of the leaky cable. Lift the leaky cable and place it on the cable support bracket 21.
[0053] Step S3: Flip the opened cable lock cover 22 to the top of the leaky cable, press the middle position of the cable lock cover 22 along the radial direction of the leaky cable, so that the circumferential limit hook 222 moves to the hook embedding groove 214 position and the auxiliary lock elastic hook 223 moves to the auxiliary lock embedding groove 2151 position. Under the squeezing action of the leaky cable, the circumferential limit hook 222 hooks the circumferential limit block 211 to form a main lock, and the auxiliary lock elastic hook 223 rebounds upward and is embedded in the auxiliary lock embedding groove 2151 and hooks the auxiliary locking part 215 to form an auxiliary lock. During this process, the axial limit part 221 of the cable lock cover 22 is correspondingly embedded in the axial limit groove 212 of the cable support bracket 21, so that the cable lock cover 22 is axially limited by the cable support bracket 21. When the circumferential limiting hook 222 hooks the circumferential limiting block 211 and the auxiliary locking elastic hook 223 is embedded in the auxiliary locking embedding groove 2151 and forms an interference fit on the contact surface and cannot move, it indicates that the leaky cable hoist has locked the leaky cable in place.
[0054] The steps for disassembling the leaky cable hanger provided by the present invention during use are as follows:
[0055] Use a lever tool to gently pry the gap between the auxiliary lock elastic hook 223 and the auxiliary lock part 215 to make the auxiliary lock elastic hook 223 pop out, then use the lever tool to continue prying the reserved disassembly hole 20 to make the circumferential limit hook part 222 pop out, pull open the cable lock cover plate 22 and push out the leaky cable to complete the separation and disassembly of the leaky cable and the leaky cable hoist.
[0056] The above descriptions are only several embodiments of the present invention. Those skilled in the art may make various changes or modifications to the embodiments of the present invention based on the contents disclosed in the application documents without departing from the spirit and scope of the present invention.
