[0002] A cable trench is a ditch excavated and built according to design requirements. The side walls of the ditch are welded with load-bearing angle steel frames and grounded as required. The underground ditch covered with a cover is a cable trench. Its purpose is to be a dedicated underground channel for laying cables. After the cables inside a cable trench are laid, according to the cable protection requirements, it is necessary to cover the cover with a bracket above the cable trench to protect the cables. The cover is generally rectangular in shape and has uniform thickness. The cover must be uncovered when laying and repairing cables. The size of the cable trench cover is usually determined according to the width and depth of the cable trench. Generally speaking, the width of the cable trench is between 200mm and 1000mm, and the depth is between 300mm and 1500mm. The size of the cable trench cover also needs to be adjusted accordingly. For a cable trench with a width of 600mm, the size of the cover may be 600mm x 300mm, and for a cable trench with a depth of 1000mm, the thickness of the cover may need to reach 50mm or more to ensure sufficient load-bearing capacity.

Urban reconstruction and new construction of wires, cables, and optical cables have been changed from open-air to underground. Therefore, the demand for cable trench covers has increased. When laying cables underground, it is necessary to first set up a cable trench underground, then lay cables in the cable trench, and finally lay covers on the upper end of the cable trench. When construction personnel inspect and replace cables in the cable trench, they need to remove the covers on the cable trench before they can carry out construction. When distribution operation and maintenance personnel perform cable trench plugging inspections and other work, they need to open the cable trench covers. The existing operation method is generally to pry open the covers with a crowbar, and multiple people lift the covers upward and move them to the designated position. Due to the large size and heavy weight of the cable trench covers in the substation, the labor intensity of the staff is relatively high, and it is also easy to cause injuries to the operation and maintenance personnel.

[0004] After searching, the Chinese invention patent with the authorization number CN109573893B discloses a new type of integrated cable trench cover prying device, including a support part, the upper and lower ends of the front side of which are respectively vertically provided with a load-bearing rod and a table top, the load-bearing rods are two and are arranged opposite to each other on the left and right, and a three-dimensional driving mechanism is arranged between the two load-bearing rods, the bottom end of which is connected with a lifting plate, and the middle of the left and right ends of the lower side of the lifting plate are respectively connected with hooks with openings facing upwards, and the upper part is provided with a suction cup mounting plate opposite to it, which is provided with a threaded hole and a through hole, a screw rod passes through the threaded hole and extends to the lifting plate, and the lifting plate is provided with a through hole that can pass through the suction cup mounting plate A guide rod, a vacuum suction cup is provided on the lower side of the suction cup mounting plate, a shovel hook is hung on the suction cup mounting plate or the lifting plate, the shovel hook includes an upper top surface and a lower bottom surface which are respectively vertically arranged on the upper and lower ends of the front side surface, the shovel hook is hung on the suction cup mounting plate or the lifting plate through the upper top surface, the vacuum suction cup is connected to the vacuum pump through a pipeline, and rollers are respectively arranged on the four corners of the bottom surface of the device; the device can automatically pry all types of cable trench covers.

After the winding roller 20 lowers the cable trench cover, the sleeve 12 and the lifting ring 13 are restored to the height before working, and the switch button of the second motor 19 is turned off.

[0056] During the specific implementation of the present new cable trench cover opening tool, the staff needs to move the tool to the top of the cable trench cover through the universal wheel 21, and the staff needs to operate the control panel 8 to turn on the switch button of the second motor 19. Then, the hook 13 is lowered close to the cable trench cover, and the distance between the two rings 12 is adjusted so that the distance between the two rings 12 is equal to the distance between the reserved holes on the cable trench cover to be opened, and the hooks 13 under the two rings 12 are respectively hung on the reserved holes of the cover. In this step, the sliding function of the rings 12 enables the hook 13 to be adaptively adjusted according to cable trench covers of different sizes, thereby ensuring the accuracy and safety of subsequent operations. The hook 13 is hung on the reserved hole of the cable trench cover. The load-bearing capacity and stability of the hook 13 are crucial, which can ensure the safe suspension and movement of the cable trench cover in subsequent operations. The second motor 19 The winding roller 20 is driven to retract the lifting rope 9, thereby lifting the cable trench cover. The self-locking function of the second motor 19 ensures the stable rotation of the winding roller and the uniform force of the lifting rope, which helps to avoid the shaking or tilting of the cable trench cover during the lifting process. After lifting the cable trench cover, press the pause button of the second motor on the operation panel 8, turn on the switch button of the first motor 6, and the first motor 6 drives the screw rod 4 to rotate. The screw rod 4 enables the movable frame 5 to move left and right, thereby driving the cable trench cover to move to the specified position. The rotating screw rod 4 drives the movable frame 5 to move, and the movable frame 5 moves the cover to the side of the cable trench, turns off the switch button of the first motor 6, turns on the switch button of the second motor 19 again, uses the winding roller 20 to lower the cover, and finally restores the lifting ring 12 and the hook 13 to the height before working, turns off the switch button of the second motor 19, and the opening work of the cable trench cover is completed.

[0057] The design of the movable frame 5 takes into account many factors, such as load-bearing capacity, stability and durability. It can ensure the stability and safety of the cable trench cover during movement. When the cable trench cover is moved to the designated position, the staff needs to perform a series of subsequent operations, such as fixing, cleaning or replacement. These operations require the assistance and support of tools to ensure the smooth progress of maintenance work. All parts of this tool have been carefully designed and manufactured. The tool also has the advantages of easy operation, safety and reliability. By providing a battery 7, it can provide electrical components with power, so there is no need to connect to an external power supply.
