[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] This invention aims to overcome the shortcomings of existing technologies, improve the convenience of changing tools during live-line work, ensure the insulation performance of insulated tools, and improve the efficiency of live-line work. This invention provides a tool placement device for live-line work sites, implemented through the following scheme: A tool placement device for live-line work sites, comprising a multi-section foldable bracket, a bracket cart, support rods, bracket hooks, dust covers, and accessory boxes 2-11, etc. The multi-section foldable bracket adopts a chain-link structure, composed of multiple sections of T-shaped chain links 1, connected to each other via a first rotating shaft 4 or a rotating shaft 2 with a support column. The main structure of the multi-section foldable bracket can be folded into a single unit in multiple directions, utilizing the self-reflective constraints between sections, and combined with chain link locks 3 to form an integral structure. The chain link lock 3 has two parts: the insertion hole and the plug, which are respectively fixed to the left and right end faces of adjacent sections that rotate clockwise; the support chassis 2-4 supports the multi-section foldable support and the accessory box 2-11; the dust cover protects the entire device from dust; and the accessory box 2-11 holds other accessories for this device. The device provided by this invention is easy and flexible to operate, improves work efficiency, and reduces the labor intensity of workers.

[0029] The features of this invention are: the entire device is foldable, and the height of the support frame can be combined at any time according to the complexity of the work and the number of tools used, meeting the needs for placing the tools used in the operation; the device is equipped with a support cart travel device, and the entire device is movable and can be used as a trolley; all four wheels are high-quality all-terrain shock-absorbing wheels, which can easily cope with various environments and facilitate the transportation of tools on the work site; the device is equipped with a dust cover to protect the tools used in the operation; the device is equipped with accessory boxes 2-11, which can hold accessories for this device and other auxiliary tools.

[0030] like Figures 1-3 As shown, the multi-section foldable bracket is composed of multiple H-shaped chain links 1. The first pivot 4 is fixed to the large flat end of the segment. The first and second connected segments can only rotate and fold in one direction, and cannot rotate in the opposite direction. The pivot 2 of the third segment, connected to the second segment, is fixed to the other end of the large flat end of the second segment in the opposite direction, so the rotation direction of the third segment is opposite to that of the second segment. Similarly, the rotation direction of the fourth segment, the third segment, and even the Nth segment is opposite to that of the previous segment, ultimately allowing all N H-shaped chain links 1 to fold together in multiple directions. The chain link lock 3 is installed on the odd-numbered H-shaped chain links 1 after the second segment and is fixed to both sides of the narrow end face of the H-shaped chain link 1 to prevent rotation. By using the reverse rotation of adjacent H-shaped chain links 1, and in conjunction with the chain link lock 3, the N H-shaped chain links 1 can be combined into a single structure. The pivot 2 with the support column is used to support the N H-shaped chain links 1 assembled into a herringbone bracket.

[0031] like Figures 4-5As shown, the right side flap 2-5 and the left side flap 2-6 of the support vehicle are fixed together by a pivot 2-10. The two side flap connecting hooks 2-1 are fixed on the long side of the right side flap 2-5. Normally, one end of the side flap connecting hook 2-1 is inserted into the connecting hook inlet hole 2-14, and the other end is inserted into the connecting hook fixing hole 2-13. The end of the side flap connecting hook 2-1 inserted into the connecting hook fixing hole 2-13 is provided with a hook fixing pin 2-2, the main purpose of which is to prevent both ends of the side flap connecting hook 2-1 from being pulled out of their respective insertion holes at the same time.

[0032] When the left flap 2-6 and right flap 2-5 are retracted, pull one end of the two side flap connecting hooks 2-1 out of the connecting hook insertion hole 2-14 respectively, and then insert them into the two side flap connecting fixing holes 2-9 on the left flap 2-6; that is, fix the right flap 2-5 and left flap 2-6 to the support vehicle chassis 2-4. Two support vehicle casters 2-3 are located at one end of the support vehicle chassis 2-4, and two support vehicle fixed wheels 2-8 are located at the other end. Both casters 2-3 and fixed wheels 2-8 are equipped with brake pads to secure the wheels. All four wheels are widened all-terrain shock-absorbing wheels, easily handling various environments. The support vehicle also has an accessory box 2-11 to store accessories and commonly used tools for the entire device. Two side flap support legs 2-7 are located at one end of the large flat surface of both the right flap 2-5 and left flap 2-6 to support the stability of the right flap 2-5 and left flap 2-6 when opened. The support rod insertion hole 2-15 is used to fix the support rod.

[0033] like Figure 6 As shown, the eccentric shaft 3-2 of the support rod and the telescopic rod 3-3 are connected together. Turning the telescopic rod 3-3 will drive the eccentric shaft 3-2 to rotate, and under the action of the eccentric shaft 3-2, the telescopic rod 3-3 can be fixed at any position inside the main rod 3-1. The front end of the telescopic rod 3-3 is provided with a support ring 3-4, which can be fitted onto the rotating shaft 2 with the support column.

[0034] like Figure 7 As shown, the fixed base 4-1 is fixed to the right flap 2-5 and the left flap 2-6. The fixed support rod 4-3 moves on the fixed base 4-1 via the support leg pivot 4-2. The movable support rod 4-4 can move back and forth within the fixed support rod 4-3. The movable support rod groove 4-7 on the movable support rod 4-4 prevents the movable support rod 4-4 from rotating within the fixed support rod 4-3. Tightening the movable support rod fastening screw 4-8 can fix the movable support rod 4-4 within the fixed support rod 4-3. The support claw 4-5 is fixed to the movable support rod 4-4 by the support claw fixing nail 4-6, increasing the contact area between the support leg and the ground.

[0035] like Figure 8As shown, the bracket hook is made of elastic material. The large hook 5-1 can be hung on the cross brace of the H-shaped chain link 1 and can move back and forth on the cross brace. The storage hook 5-2 is used to hang live-line working tools and insulating items such as insulating clothing and safety helmets.

[0036] like Figures 9-11 As shown, the dust cover bracket 6-1 provides support for the entire dust cover; the dust cover is made of insulating dense woven mesh fabric 6-2, and has double-headed bidirectional zippers 6-3 in the center of the perimeter, which can be pulled up or down for easy access; the dust cover bracket cross brace 6-4 can fix the entire dust cover on the multi-section foldable bracket.

[0037] The live-line work site tool placement device is equipped with matching soft insulating cloth, which matches the dimensions of the support vehicle chassis 2-4, right side flap 2-5, and left side flap 2-6. When not in use, it can be folded and stored in the accessory box 2-11. In addition, it is also equipped with insulating elastic binding straps to fix the insulating tools placed on the multi-section foldable support, so as to prevent the insulating tools from colliding with each other when the tools are placed and moved, effectively ensuring the insulation performance of the insulating tools.

[0038] Based on the above-described tool placement device for live-line work, the present invention also provides a method for using the placement device: First, push the support vehicle push rod 2-12 to move the live-line work site tool placement device to the work site. Since the support vehicle chassis 2-4 is equipped with two swivel wheels 2-3 and two fixed wheels 2-8, all four wheels are widened all-terrain shock-absorbing wheels, easily handling various environments. Upon arrival at the site, depress the brake pads on the two swivel wheels 2-3 and the two fixed wheels 2-8 to secure the four wheels. Pull out the side-flip plate connecting hook 2-1 from the side-flip plate connecting fixing hole 2-9, and then insert it into the connecting hook retraction hole 2-14. Lower the right side-flip plate 2-5 and the left side-flip plate 2-6. According to the terrain, pry open the side-flip plate support legs 2-7, loosen the movable support rod fastening screw 4-8, adjust the length of the movable support rod 4-4 extending from the fixed support rod 4-3, ensuring that the claw fixing nail 4-6 is firmly inserted into the ground, and then tighten the movable support rod fastening screw 4-8.

[0039] Based on the complexity of the live-line work on site, unfold and lay out the required number of H-shaped chain links 1, and lock the chain link lock 3. Do not lock the chain link lock 3 on adjacent H-shaped chain links 1 that need to be folded. Then, prop up the assembled H-shaped chain link 1 group to form a herringbone bracket. Insert the support rings 3-4 of the two support rods onto the two ends of the rotating shaft 2 with support columns at the folding point, grip the telescopic rod 3-3, and rotate the main rod 3-1 to loosen the locking state of the eccentric shaft 3-2, allowing the main rod 3-1 and the telescopic rod 3-3 to move freely. Insert the other end of the main rod 3-1 into the support rod insertion hole 2-15 on the chassis. Adjust the extension length of the telescopic rod 3-3 to support the formed herringbone bracket, grip the telescopic rod 3-3, rotate the main rod 3-1 to tighten the eccentric shaft 3-2, and lock the main rod 3-1 and the telescopic rod 3-3 so that they cannot move.

[0040] At this point, lay down the soft insulating cloth on the support chassis 2-4, right-side flip-up 2-5, and left-side flip-up 2-6 of the live-line work site tool placement device. Select the required number of support hooks based on the complexity of the live-line work and hang them in appropriate positions. Install and secure the dust cover bracket 6-1, cover it with the insulating densely woven mesh cover 6-2, and open the double-ended two-way lock 6-3. Arrange the live-line work site tools according to their designated areas. Long tools can be placed on the A-frame supports, ropes and insulating clothing can be hung on the hooks 5-2, and heavy objects and instruments can be placed on the support chassis 2-4, right-side flip-up 2-5, and left-side flip-up 2-6. After all the necessary live-line work site tools are in place, pull the double-ended two-way lock 6-3 to effectively protect the placed tools.

[0041] As is known from common technical knowledge, the present invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones; all modifications within the scope of the present invention or equivalent to the scope of the present invention are included in the present invention.
