Description

Technical Field

[0001] This invention belongs to the field of hanging racks and warning signs, and relates to a hanging rack that is easy to operate and hang at a low position. Background Technology

[0002] Warning signs, directional signs, and other installations that need to be hung at high locations are typically suspended from cables or poles using hangers. Traditional hangers require ladders or similar equipment to transport personnel to the height for hanging, which not only necessitates a vehicle and occupies ground space but is also inefficient and poses safety hazards during the hanging process. Furthermore, traditional hangers often lack sufficient clamping force, leading to slippage along cables or poles in windy conditions. This not only poses a safety risk but can also cause warning and directional signs to become misaligned, rendering them ineffective. Summary of the Invention

[0003] This invention primarily addresses the problems of existing hanging racks requiring operation at heights, which are inconvenient and pose safety hazards. It provides a hanging rack that facilitates low-level operation, allowing for suspension from the ground to higher positions, improving work efficiency, and enhancing safety and reliability. This invention also solves the problem of insufficient clamping force in traditional hanging racks, making them prone to shifting in windy weather.

[0004] The technical solution adopted by this invention to solve its technical problem is: a hanging bracket that is easy to operate and suspend at low positions, used to suspend cables and hanging poles, including a strip-shaped bracket body, with a hanging object fixed below the bracket body, and hanging parts at both ends of the bracket body. The hanging parts include a liftable Y-shaped lower clamping block, with support seats on both outer sides of the Y-shaped lower clamping block. The upper ends of the two support seats are connected to upper swing clamps by torsion springs. The upper swing clamps of the two support seats are symmetrically arranged, and the upper swing clamps have a protruding part near the root of the torsion spring. When the Y-shaped lower clamping block rises, the protruding part abuts against the outer wall of the upper end of the Y-shaped lower clamping block, and the upper swing clamps unfold vertically. When the Y-shaped lower clamping block falls, the protruding part disengages from the outer wall of the Y-shaped lower clamping block, and the upper swing clamps swing inward and downward to clamp. This device can be used to quickly install indicator or warning signs on cables and poles at high outdoor locations. Taking high-voltage lines as an example, some high-voltage cables are laid on utility poles in some outdoor locations. Near ponds, fishing enthusiasts often risk casting their lines onto high-voltage lines, necessitating the hanging of warning signs to indicate the high-voltage danger. Additionally, some cables cross roads, requiring the hanging of signs to indicate height restrictions. Existing mounting brackets require climbing to install, which is extremely inconvenient. This mounting system allows for the direct installation of signs and warning signs on the ground. During installation, the Y-shaped lower clamping block rises to its top position, and the upper swinging clamping plate unfolds outward through its protruding part. At this point, the mounting bracket is lifted upward using a long-handled fork, aligning the unfolded opening of the upper swinging clamping plate with the cable. A forceful upward push causes the cable to press down on the Y-shaped lower clamping block, disengaging the protruding part of the upper swinging clamping plate from the outer wall of the Y-shaped lower clamping block. Under the action of a torsion spring, the clamping plate closes inward and downward. A pivot is fitted inside the torsion spring, passing through a support base, and clamps the cable. Installation can be completed quickly. The fork's rod can be assembled from links. For installation locations that are too high, drones can also be used for installation.

[0005] Preferably, metal reinforcing plates are attached to the outer walls of both sides of the Y-shaped lower clamping block. The Y-shaped lower clamping block is made of plastic or rubber. Based on experience with traditional clamping devices, when the clamping force is too large, the bifurcated area of ​​the two arms of the Y-shaped lower clamping block is prone to cracking. Therefore, this device attaches metal reinforcing plates to the outer wall of the Y-shaped lower clamping block to bear the stress and prevent cracking. On this basis, an upper swinging clamping plate with a larger clamping force can be selected to provide a greater clamping force.

[0006] Preferably, the top surface of the Y-shaped lower clamping block is a concave arc surface, and the top surface of the Y-shaped lower clamping block is provided with protruding spikes. For some thicker cables, the upper swinging clamp, under the action of the torsion spring, works with the Y-shaped lower clamping block to clamp the cable. The spikes of the Y-shaped lower clamping block can increase the clamping effect with the cable sheath, preventing swinging and slippage.

[0007] Preferably, the top surface of the Y-shaped lower clamp block is a concave arc surface, and the top surface of the Y-shaped lower clamp block is provided with a groove for embedding steel nails or injecting adhesive. When the cable surface has high hardness, or when the cable has an oil-repellent surface adhesive that cannot adhere, and when it is difficult for sharp spikes to penetrate the cable sheath, steel nails can be glued into the groove and driven into the cable sheath to improve the fixing performance. It should be noted that the length of the steel nail should not exceed the thickness of the outermost sheath of the cable to avoid piercing the cable surface and touching the cable core. For some steel cables or ordinary PVC cables, adhesive can be injected into the groove to improve the bonding between the bracket and the cable.

[0008] Preferably, the top surface of the Y-shaped lower clamping block is provided with a roller groove, in which a roller is detachably embedded. The two ends of the roller are rotatably mounted on the two ends of the roller groove, while the middle of the roller is suspended in the roller groove. The middle of the roller has knurling. Two roller grooves are provided, symmetrically arranged on both sides of the top surface of the Y-shaped lower clamping block. For some cables with smaller outer diameters, the clamping force of the hanger is insufficient, and after prolonged windy weather, the tags on the hanger cannot return to their original position after rotating a certain angle, causing the hanger to remain tilted for a long time, affecting its warning function. For this type of cable, a roller can be embedded in the roller groove on the top surface of the Y-shaped lower clamping block. When blown by the wind, the hanger can swing around the cable under the action of the roller, and automatically return to its original position when the wind stops. The knurling structure on the roller creates a swinging track on the cable surface, allowing the hanger to swing in its original position without easily slipping laterally.

[0009] Preferably, the bottom surface of the Y-shaped lower clamping block is provided with a guide post for inserting into the bracket body, and a clamping spring is also provided between the bottom surface of the Y-shaped lower clamping block and the bracket body. The clamping spring ensures that, in the pre-installation state, the Y-shaped lower clamping block is held upward, and the upper swinging clamp is pushed outward by the side walls. At this time, the pushing force between the Y-shaped lower clamping block and the upper swinging clamp is a lateral force, and the clamping spring is a vertical force. The two are perpendicular to each other and will not collide with each other. During installation, the torsion spring swings downward, cooperating with the clamping spring to push upward, firmly clamping the cable.

[0010] Preferably, the upper swing clip is made of bent steel wire.

[0011] Preferably, the outer side of the mounting portion is provided with a fork lug for positioning with the lifting fork, and the fork lug has a fork groove with an opening at the lower end. The fork lug can be used to position the lifting pole.

[0012] Preferably, the bracket body is a sealed structure with an internal lighting circuit. This lighting circuit includes a magnetic switch. A magnet placement slot is located on the top surface of the bracket body, aligned with the magnetic switch, for placing a magnet. A sealing film is affixed to the outside of the magnet placement slot. The magnetic switch is deactivated when the magnet is near it and remains on when no magnet is present. The lighting circuit uses a conventional power supply and lighting lamp connection structure. The switch is magnetically controlled; it deactivates when a magnet is near and reactivates when the magnet is removed. The internal circuitry of the bracket body is waterproofed. The control circuit switch is a magnetically controlled switch, integrally sealed and waterproofed with the circuit, using contactless magnetic control. After production and before installation, a magnet is placed in the magnet placement slot and sealed with a film to secure it. The magnet attracts the magnetic switch, deactivating it. Before installation, the film is removed to remove the magnet, ensuring the circuit is connected, and then installation can proceed.

[0013] Preferably, the bottom surface of the hanging bracket is provided with a rain guard strip, and the suspended object is hung below the rain guard strip. The width of the rain guard strip is greater than the width of the suspended object. The two sides of the rain guard strip are upturned, and the two ends of the rain guard strip are open to serve as drainage ends. The rain guard strip is a groove-shaped strip with openings on both sides, and its width is greater than that of the suspended object to prevent rain streaks from forming on the surface of the suspended object.

[0014] Preferably, the mounting bracket has strip-shaped solar panels on both sides, with swing brackets at both ends. The swing brackets are rotatably mounted on a support base, coaxially arranged with the upper swing clamps. A circular chuck is located outside the swing bracket's pivot, with several positioning slots around its circumference. The support base has a locking strip mounting slot, into which elastic locking strips that can engage with the positioning slots of the circular chuck are inserted. When the cable or pole suspended by the bracket runs east-west, and the strip-shaped solar panels are oriented north-south, the southern strip-shaped solar panel is adjusted to a tilt angle close to the latitude, and the northern strip-shaped solar panel is flipped above the horizontal plane to receive sunlight from the south. When the cable or pole suspended by the bracket runs north-south, and the strip-shaped solar panels are oriented east-west, the east and west solar panels are adjusted to a near-horizontal position to improve solar power generation efficiency.

[0015] This invention can be operated from the ground, directly suspending the bracket from cables and poles at a high position, improving installation efficiency, reducing installation costs, and enhancing construction safety. This invention also features superior clamping performance, preventing bracket movement. Furthermore, the strip-shaped solar panels can be oriented according to the cable or pole routing, improving the solar panel's power generation efficiency. Attached Figure Description

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] Example 1: A hanging bracket that facilitates low-level operation, such as... Figure 1 As shown. The bracket in this embodiment is used to hang a "High Voltage Danger" warning sign 3 on a high-voltage cable.

[0028] like Figure 1As shown, this device includes a strip-shaped hanging frame body 1, with a warning sign 3 fixed below it. Strip-shaped solar panels 2 are respectively installed on both sides of the hanging frame body. The hanging frame body has an internal lighting circuit with a magnetic switch. The circuitry inside the hanging frame body, including the switch, is waterproofed and sealed using a grouting method. The magnetic switch is controlled by a magnet without contact. A magnet placement groove 5 is provided on the side of the hanging frame body, aligned with the magnetic switch, for placing a magnet block. A sealing film is affixed to the outside of the magnet placement groove. The magnetic switch is disconnected when the outside of the magnet block is near it and normally connected when there is no magnet block. Hanging parts 4 are provided at both ends of the hanging frame body. Fork ears 14, which are positioned with a lifting fork, are provided on the outside of the hanging part 4. The fork ears have vertically penetrating fork grooves. A rainproof strip 15 is provided on the bottom surface of the hanging frame body 1. The suspended object is hung below the rainproof strip. The width of the rainproof strip 15 is greater than the width of the warning sign 3. The two sides of the rainproof strip 15 curve upwards, and the two ends of the rainproof strip are open as drainage ends.

[0029] The structure of the mounting part 4 is as follows Figure 2 , 3 As shown in Figure 4, the mounting part 4 includes a liftable Y-shaped lower clamping block 7. The Y-shaped lower clamping block 7 is made of plastic or rubber, and metal reinforcing plates 8 are attached to the outer walls of both sides of the Y-shaped lower clamping block. The metal reinforcing plates can be made of stainless steel, which is not easy to rust under long-term sun and rain conditions. The bottom surface of the Y-shaped lower clamping block 7 is provided with a guide post 16 for inserting into the bracket body, and a tensioning spring 17 is also provided between the bottom surface of the Y-shaped lower clamping block and the bracket body. The top surface of the Y-shaped lower clamping block 7 is a concave arc surface, and the top surface of the Y-shaped lower clamping block is provided with protruding spikes 11. The top surface of the Y-shaped lower clamping block is also provided with grooves 12 for embedding steel nails or injecting adhesive in the gaps between the spikes.

[0030] Support seats 6 are respectively provided on the two outer sides of the Y-shaped lower clamping block. The upper ends of the two support seats are connected to upper swing clamping plates 9 via torsion springs. The upper swing clamping plates and torsion springs are integrally bent from steel wire. The torsion springs are sleeved on a rotating shaft 10, which passes through the support seats. The upper swing clamping plates of the two support seats are symmetrically arranged, and each upper swing clamping plate has a protruding part 18 near the root of the torsion spring. Figure 4 As shown, when the Y-shaped lower clamping block 7 rises to its highest position, the ejector part 18 abuts against the outer wall of the metal reinforcing plate 8 at the upper end of the Y-shaped lower clamping block 7, and limits the upward vertical expansion of the swinging clamping plate 9; as Figure 3 As shown, when the Y-shaped lower clamping block descends, the protruding part disengages from the outer wall of the Y-shaped lower clamping block, and the upper swing clamping piece 9 swings inward and downward to clamp.

[0031] like Figure 5 , 6As shown, the strip solar panel 2 has swing frames 19 at both ends. The swing frames are rotatably mounted on the support base 6. The swing frames 19 are coaxially arranged with the upper swing clamp 9. A circular chuck is provided outside the swing frame shaft. The circular chuck has several positioning slots 20 around its circumference. The support base has a clip mounting groove 13. An elastic clip 21 that can be inserted into the positioning slot of the circular chuck is inserted into the clip mounting groove 13. The mounting groove 13 on the support base has two intermittent insertion holes at the end away from the circular chuck, and an elongated hole at the end closer to the circular chuck. The elastic clip 21 is U-shaped. The closed end of the elastic clip 21 is engaged with one end of the intermittent insertion hole in the mounting groove 13, and the open end of the elastic clip 21 extends out from one end of the elongated hole. Both arms of the open end of the elastic clip are upturned. The lower arm of the open end of the elastic clip is longer than the upper arm. The upper arm of the open end of the elastic clip is used for positioning itself with the mounting groove 13, and the lower arm of the open end of the elastic clip is used to elastically engage with the positioning slot 20 to position the strip solar panel.

[0032] Example 2: A hanging bracket that facilitates low-level operation, such as... Figure 8 As shown. The mounting part in this embodiment is different from that in embodiment 1, but the rest of the components are the same as those in embodiment 1.

[0033] In this embodiment, the structure of the mounting part is as follows: Figure 8 As shown, the structure of the mounting part 4 is as follows: Figure 2 , 3 As shown in Figure 4, the mounting part 4 includes a liftable Y-shaped lower clamping block 7. The Y-shaped lower clamping block 7 is made of plastic or rubber, and metal reinforcing plates 8 are attached to the outer walls of both sides of the Y-shaped lower clamping block. The metal reinforcing plates can be made of stainless steel, which is not easy to rust under long-term sun and rain conditions. The bottom surface of the Y-shaped lower clamping block 7 is provided with a guide post 16 for inserting into the bracket body. A tensioning spring 17 is also provided between the bottom surface of the Y-shaped lower clamping block and the bracket body. The top surface of the Y-shaped lower clamping block 7 is symmetrically provided with roller grooves 22 on both sides. Rollers 23 are detachably embedded in the roller grooves 22. The two ends of the rollers are rotatably mounted on the two ends of the roller grooves, and the middle part of the rollers is suspended in the roller grooves. The middle part of the rollers is knurled. The top surface of the Y-shaped lower clamping block 7 is provided with a groove 12 between the two roller grooves, and steel nails 24 can be embedded in the groove.

[0034] In this embodiment, roller 23 and steel nail 24 are optional. When the cable outer diameter is small, roller is used instead of steel nail. In this case, the bracket can be swayed or rotated by the wind in windy weather. Because the roller knurls grooves on the cable surface for positioning, the bracket is not easy to slide laterally. When the cable is thicker or the bracket must be completely positioned relative to the cable, steel nail is embedded in the groove instead of roller. The steel nail is driven into the surface of the cable for positioning.
