Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically a practical cable suspension device. Background Technology

[0002] Cable suspension devices are important auxiliary equipment for cable wiring in coal mines and other industrial fields. They play a key role in fixing and supporting cables, and their design and application have a direct impact on the safety and service life of cables.

[0003] However, existing cable suspension devices have certain shortcomings in use. When fixing cables, their sharp edges may scratch the cable sheath during installation, adjustment, or maintenance, leading to damage to the cable insulation layer. Inadequate design or improper installation of existing cable suspension devices can cause cable instability. In complex environments such as coal mines, cables are prone to swaying or falling off when subjected to vibration, tension, or external forces, increasing the risk of cable failure. Furthermore, the height adjustment of existing cable suspension devices may not be flexible or convenient enough to quickly adapt to different cable laying height requirements, resulting in reduced construction efficiency. This increases construction difficulty and cost. Existing cable suspension devices do not make full use of recycled materials, resulting in a large consumption of new materials and high production costs, which is inconsistent with the concepts of green environmental protection and sustainable development. At the same time, the materials of the device have poor recyclability, and when construction conditions change or the device is adjusted later, the maximum utilization of materials cannot be achieved, which reduces the economic benefits and environmental value of the device. Existing cable suspension devices are not easy to replace quickly. When the number of cables changes or the brackets fail, the process of replacing the brackets is complicated and time-consuming, affecting the cable laying period and construction continuity. In addition, the maintenance of the brackets is not convenient enough, which reduces maintenance efficiency and increases maintenance costs. Utility Model Content

[0004] In view of the problems in the prior art, this utility model provides a practical cable suspension device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a practical cable suspension device, including an installation anchor rod, a threaded anchor rod, a connecting sleeve, and a bracket. The bottom end of the installation anchor rod is connected to the top end of the threaded anchor rod through the connecting sleeve. Several brackets are raised and lowered on the threaded anchor rod. Each bracket is equipped with several saddle wheel sets. The installation anchor rod and the threaded anchor rod are connected through the connecting sleeve to form a stable suspension system, providing a reliable foundation for cable suspension. The raising and lowering of the brackets is coordinated with the threaded anchor rods, which can adjust the height of the brackets according to actual needs. Each bracket is equipped with several saddle wheel sets, which can effectively support and guide the cable, reducing friction and wear of the cable during the laying process.

[0006] The bracket includes a sleeve and a crossbeam. The crossbeam is horizontally positioned and has a through hole in the center. The sleeve is welded to the bottom of the crossbeam and aligned with the through hole. Both the sleeve and the crossbeam are fitted onto the threaded anchor rod. This design allows the bracket to move freely up and down on the threaded anchor rod.

[0007] Preferably, the anchor rod has a first annular groove near its bottom, and the threaded anchor rod has a second annular groove near its top. A connecting sleeve is fitted over the joint of the anchor rod and the threaded anchor rod, with both annular grooves one and two located inside the connecting sleeve. Two insertion holes are provided at each end of the connecting sleeve corresponding to annular grooves one and two. A U-shaped locking pin is inserted into each insertion hole at both ends of the connecting sleeve, and the two locking pins respectively engage with annular grooves one and two. This device achieves a tight connection between the anchor rod and the threaded anchor rod by having an annular groove one near its bottom and an annular groove two near its top, with the connecting sleeve fitted over the joint of the anchor rod and the threaded anchor rod, and both annular grooves one and two located inside the connecting sleeve, and the U-shaped locking pins engaging with the annular grooves.

[0008] Preferably, a support plate is welded to the bottom of the sleeve and the crossarm, and several saddle wheel sets on the top of the crossarm are symmetrically arranged on both sides of the through hole.

[0009] Preferably, the threaded anchor rod is threaded with a nut, which is located below several brackets, and the diameter of the nut is larger than the inner diameter of the sleeve. The brackets are fixed by adjusting the position of the nut to ensure the stable suspension of the cable. At the same time, the height of the bracket can be adjusted by rotating the nut and adjusting its position on the threaded anchor rod. These flexible structural designs enable the device to adapt to various complex construction environments and different cable laying requirements.

[0010] Preferably, the saddle wheel set includes a wheel frame and a tow wheel. The wheel frame is fixed to the top of the crossbeam by bolts, and the tow wheel rotates and engages with the wheel frame.

[0011] Preferably, the diameters at both ends of the towing wheel are larger than the diameter at the middle. This design can effectively support and guide the cable, preventing the cable from shifting or falling off during the laying process. The wheel frame is a "U"-shaped structure with different heights at both ends, and two mounting holes are opened on the high side of the wheel frame for subsequent installation of wire rope clips.

[0012] The beneficial effects of this utility model are:

[0013] (1) The present invention provides a practical cable suspension device. The installation anchor rod and the threaded anchor rod are connected by a connecting sleeve to form a stable suspension system, which provides a reliable foundation for cable suspension, avoids cable instability, and is not prone to shaking or falling off when the cable is subjected to vibration, tension or external force, thereby reducing the risk of cable failure. The lifting mechanism of the bracket is coordinated with the threaded anchor rod, which can adjust the height of the bracket according to actual needs, thereby adapting to the cable laying requirements of different heights. Each bracket is equipped with several saddle wheel sets, which can effectively support and guide the cable, reduce the friction and wear of the cable during the laying process, and improve the laying speed.

[0014] (2) The present invention provides a practical cable suspension device. This cable suspension device has high environmental protection and economy in terms of material use. Compared with the support, the cable is relatively light and the laying process is not complicated. Therefore, it can make full use of the recycled anchor rods to make the installation anchor rods and threaded anchor rods of the cable laying suspension device. This waste recycling and reuse method not only reduces the consumption of new materials and lowers the production cost, but also conforms to the concept of green and environmentally friendly sustainable development. In addition, if the construction conditions change later or the device needs to be adjusted, all materials except the installation anchor rods can be recycled and reused. This material recyclability makes the device highly flexible and maintainable during use, and can maximize the use of materials in different construction stages and environments, further improving the economic benefits and environmental value of the device.

[0015] (3) The present invention provides a practical cable suspension device in which the bracket is fitted onto a threaded anchor rod. By unscrewing the nut, the bracket can be quickly replaced. This allows for the selection of crossarms of appropriate length and the installation of a corresponding number of saddle wheel sets based on the number of cables, thus adapting to various cable suspension needs. This design enables the device to flexibly handle laying tasks with different numbers of cables without frequent replacements or the addition of other equipment, improving the device's practicality and economy. Furthermore, it facilitates bracket maintenance, improving maintenance efficiency. When the bracket malfunctions or needs replacement, simply unscrewing the nut is sufficient. This allows for quick removal of the bracket from the threaded anchor rod for repair or replacement, reducing the impact of bracket failure on the cable laying schedule and ensuring the continuity and stability of the cable laying work. Furthermore, when encountering roadways with significant undulations or when cable laying is required at specific locations, the bracket can be reversed and placed on the threaded anchor rod at appropriate and fixed locations within the roadway. This ensures that the cable receives appropriate tension during laying, preventing cable damage or laying difficulties caused by friction against the roadway roof. This device can adapt to various complex roadway environments and meet the cable laying needs under different construction conditions, demonstrating strong adaptability and flexibility.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-8As shown, this utility model discloses a practical cable suspension device, comprising an anchor rod 1, a threaded anchor rod 2, a connecting sleeve 3, and brackets 5. The bottom end of the anchor rod 1 is connected to the top of the threaded anchor rod 2 via the connecting sleeve 3. Several brackets 5 are raised and lowered on the threaded anchor rod 2, and each bracket 5 is equipped with several saddle wheel sets 6. The anchor rod 1 and the threaded anchor rod 2 are connected by the connecting sleeve 3 to form a stable suspension system, providing a reliable foundation for cable suspension. The raising and lowering of the brackets 5 on the threaded anchor rod 2 allows for adjustment of the bracket height according to actual needs, thereby adapting to cable laying requirements at different heights. Each bracket 5 is equipped with several saddle wheel sets 6, which effectively support and guide the cable, reducing friction and wear during cable laying and increasing laying speed. Since the brackets 5 are mounted on the threaded anchor rod 2 by nuts 7, they are easy to disassemble. This allows for adjustment based on the number of cables laid during actual construction. The quantity of brackets 5 can be reasonably selected for assembly, and the appropriate size of brackets 5 can be selected for use according to the cable laying environment, making the use of the device more flexible. The cable suspension device has high environmental protection and economy in terms of material use. Compared with the support, the cable is relatively light and the laying process is not complicated. Therefore, the recycled anchor rods can be fully utilized to make the installation anchor rods 1 and threaded anchor rods 2 of the cable laying suspension device. This waste recycling and reuse method not only reduces the consumption of new materials and lowers the production cost, but also conforms to the concept of green and environmentally friendly sustainable development. In addition, if the construction conditions change later or the device needs to be adjusted, all materials except the installation anchor rods 1 can be recycled and reused. This recyclability of materials makes the device highly flexible and maintainable during use, and can maximize the utilization of materials in different construction stages and environments, further improving the economic benefits and environmental value of the device.

[0028] The bracket 5 includes a sleeve 501 and a crossarm 502. The crossarm 502 is horizontally positioned and has a through hole 503 in its center. The sleeve 501 is welded to the bottom of the crossarm 502 and aligned with the through hole 503. Both the sleeve 501 and the crossarm 502 are fitted onto the threaded anchor rod 2. This design allows the bracket 5 to move freely up and down on the threaded anchor rod 2, adapting to cable laying requirements at different heights. The bracket 5 of this cable suspension device is fitted onto the threaded anchor rod 2. After unscrewing the nut 7, the bracket 5 can be quickly replaced. This allows for the selection of a crossarm 502 of appropriate length and the installation of a corresponding number of saddle wheel sets 6 on the crossarm 502 according to the number of cables, thus adapting to more cable suspension needs. This design makes the device flexible. To handle cable laying tasks with varying quantities, the device eliminates the need for frequent replacements or additional equipment, enhancing its practicality and economy. Furthermore, it facilitates maintenance of the bracket 5, improving maintenance efficiency. When the bracket 5 malfunctions or needs replacement, simply unscrewing the nut 7 allows for quick removal from the threaded anchor rod 2 for repair or replacement, minimizing the impact of bracket 5 malfunctions on cable laying schedules and ensuring the continuity and stability of cable laying operations. Moreover, when encountering uneven roadways or situations requiring cable laying at specific locations, the bracket 5 can be reversed and mounted on the threaded anchor rod 2 at appropriate and fixed locations within the roadway. This ensures the cable receives appropriate tension during laying, preventing cable damage or laying difficulties due to friction with the roadway roof. This allows the device to adapt to various complex roadway environments, meeting cable laying needs under different construction conditions, demonstrating strong adaptability and flexibility.

[0029] In one optional embodiment of this invention, the anchor rod 1 has a first annular groove 101 near its bottom end, and the threaded anchor rod 2 has a second annular groove 201 near its top end. A connecting sleeve 3 is fitted onto the joint between the anchor rod 1 and the threaded anchor rod 2, with both the first annular groove 101 and the second annular groove 201 located within the connecting sleeve 3. Two insertion holes 301 are provided at both ends of the connecting sleeve 3, corresponding to the first annular groove 101 and the second annular groove 201. A U-shaped locking pin 4 is inserted into each of the insertion holes 301 at both ends of the connecting sleeve 3. The two locking pins 4 are respectively engaged in the first annular groove 101 and the second annular groove 201. The device has an annular groove 101 near the bottom end of the anchor rod 1 and an annular groove 201 near the top end of the threaded anchor rod 2. The connecting sleeve 3 is fitted onto the joint between the anchor rod 1 and the threaded anchor rod 2. At the joint between anchor rod 1 and threaded anchor rod 2, with annular groove 101 and annular groove 201 both located within connecting sleeve 3, a U-shaped locking pin 4 engages with the annular groove, achieving a tight connection between anchor rod 1 and threaded anchor rod 2. This connection method offers high stability and reliability, capable of withstanding significant tensile and compressive forces, ensuring the safety of the device during use. Furthermore, the connection between anchor rod 1 and threaded anchor rod 2 via connecting sleeve 3 and locking pin 4 is simple to operate, requiring no complex tools or steps, greatly simplifying the installation process and improving efficiency. When maintenance or component replacement is required, simply pull locking pin 4 out of insertion hole 301 to quickly disassemble connecting sleeve 3, thereby separating anchor rod 1 and threaded anchor rod 2. The threaded anchor rod 2 facilitates the inspection, repair, or replacement of various components. This convenient disassembly and assembly design not only improves maintenance efficiency but also reduces maintenance costs and extends the service life of the device. Furthermore, because the two locking pins 4 respectively engage with the annular groove 101 and annular groove 201, the threaded anchor rod 2 can rotate relative to the installed anchor rod 1 after installation. This allows for flexible adjustment of the angle of the threaded anchor rod 2 as needed, enabling the device to better adapt to different installation environments and requirements, thus improving its adaptability and flexibility. Moreover, the bracket 5 is raised and lowered on the threaded anchor rod 2. The rotatability of the threaded anchor rod 2 makes adjusting the position of the bracket 5 more flexible. When laying cables at different heights, the threaded anchor rod 2 can be rotated to adjust its position. The rod 2 is used to quickly adjust the height of the bracket 5 to adapt to the suspension requirements of different cables, improving the ease of use and work efficiency of the device. Since the device can rotate relative to the anchor rod 1 and the threaded anchor rod 2 after assembly, in practical applications, the space is limited on the threaded anchor rod 2, which is not conducive to the use of pneumatic tools. Therefore, a nut is welded to the bottom of the threaded anchor rod 2. The threaded anchor rod 2 is rotated by the nut. The nut is welded to the bottom of the threaded anchor rod 2, which has sufficient operating space and can be used with pneumatic tools. The nut is driven by the pneumatic tool, and the nut drives the threaded anchor rod 2 to rotate. Only the rotation of the nut 7 needs to be limited, so the nut 7 can be quickly disassembled and installed. By quickly disassembling and assembling the nut 7, the position of the bracket 5 on the threaded anchor rod 2 can be easily adjusted.

[0030] In one optional embodiment of this example, a support plate 504 is welded to the bottom of the sleeve 501 and the crossarm 502. Several saddle wheel sets 6 on the top of the crossarm 502 are symmetrically arranged on both sides of the through hole 503. The symmetrical arrangement of the saddle wheel sets 6 can make the tension and pressure on the cable on the crossarm 502 evenly distributed, avoiding deformation or damage to the crossarm 502 or the saddle wheel sets 6 due to uneven force. Since the saddle wheel sets 6 are symmetrically distributed on both sides of the through hole 503, they can effectively distribute the weight of the cable, allowing the bracket 5 to bear more cables and improving the load-bearing capacity of the device. The support plate 504 is welded to the bottom of the sleeve 501 and the crossarm 502, providing additional support points for the crossarm 502, enhancing the stability of the entire bracket 5 structure, and ensuring that the crossarm 502 will not tilt or shift due to gravity or external force during cable suspension.

[0031] In one optional embodiment of this invention, a nut 7 is threaded onto the threaded anchor rod 2. The nut 7 is located below several brackets 5, and the diameter of the nut 7 is larger than the inner diameter of the sleeve 501. The brackets 5 are fixed by adjusting the position of the nut 7 to ensure the stable suspension of the cable. At the same time, by rotating the nut 7, the position of the nut 7 on the threaded anchor rod 2 is adjusted, thereby realizing the adjustment of the height of the brackets 5. These flexible structural designs enable the device to adapt to various complex construction environments and different cable laying requirements, and it has strong adaptability.

[0032] In one optional embodiment of this example, the saddle wheel assembly 6 includes a wheel frame 601 and a tow wheel 602. The wheel frame 601 is fixed to the top of the crossbeam 502 by bolts, and the tow wheel 602 rotates and engages with the wheel frame 601.

[0033] In one optional embodiment of this example, the diameters at both ends of the towing wheel 602 are larger than the diameter at the middle. This design can effectively support and guide the cable, prevent the cable from shifting or falling off during the laying process, and further improve the safety of construction. The wheel frame 601 is a "U"-shaped structure with different heights at both ends. The high side of the wheel frame 601 has two mounting holes for subsequent installation of wire rope clips.

[0034] In use, firstly, drill holes at the predetermined installation position on the top of the tunnel to fix and install anchor rod 1, ensuring the stability of anchor rod 1 for subsequent component installation. Connect threaded anchor rod 2 to anchor rod 1 using connecting sleeve 3. Sleeve connecting sleeve 3 over the joint between anchor rod 1 and threaded anchor rod 2, aligning annular groove 101 and annular groove 201. Then, insert U-shaped locking pins 4 into the insertion holes 301 at both ends of connecting sleeve 3, locking them into the annular grooves to achieve a tight connection between anchor rod 1 and threaded anchor rod 2. Select an appropriate number of brackets 5 according to the number and specifications of the cables. Several saddle wheel sets 6 are installed on each bracket 5. The bracket 5 is then fitted onto the threaded anchor rod 2 and supported and fixed by nuts 7. The height of the bracket 5 is adjusted to meet the cable laying height requirements. Then, at the beginning of the tunnel, a cable reel and wire rope reel A are installed, and at the end of the tunnel, a winch is installed. The winch's wire rope B is laid along the tunnel to the beginning and connected to wire rope A. All equipment is ensured to be securely installed and reliably connected. A fixed pulley is installed at both the beginning and end of the tunnel. The upper rim of the pulley should be higher than the cable laying suspension device's tow wheel 602 to facilitate the laying of the wire rope. The smooth passage of the rope leads the cable out of the cable reel and secures it tightly to the wire rope on wire rope reel A, ensuring a firm binding to prevent it from falling off during laying. The winch is then started, driving it to pull wire ropes A and B. Wire rope A pulls the cable along the entire tunnel. During laying, the cable rolls along the pulley 602, with wire rope A under tension while the cable itself is not, reducing cable wear and damage. At regular intervals, the binding of wire rope A and the cable is fixed to the high side of the pulley frame 601 to prevent the cable from shifting back and forth during laying, ensuring stable cable laying. When the cable is finally laid... At the beginning of the retrieval process, leave sufficient length of the end of wire rope A and leave the binding of wire rope A and the cable on site for subsequent retrieval. Finally, at the beginning of the tunnel, install a winch and a cable roller. The winch is used to retrieve wire rope A, and the cable roller is used to retrieve the cable. Connect the wire rope A from the winch to the previously left end of wire rope A, ensuring a secure connection. Start the winch to retrieve both wire rope A and the cable simultaneously. During the retrieval process, the cable continues to roll along the trolley 602. Wire rope A is under tension, while the cable is not, which effectively protects the cable and prevents damage during retrieval.
