Technical Field

[0001] The utility model relates to the technical field of tower crane cable protection, in particular to a tower crane cable insulation protection device. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also known as "tower crane". It is connected in sections (referred to as "standard sections") and is used to lift raw materials for construction such as steel bars, wooden slats, concrete, steel pipes, etc. Tower crane is an indispensable equipment on construction sites.

[0003] Existing tower crane cables often flutter back and forth in the wind, and there may be a risk of being blown off. If the cables are fixed to the tower body with wire, the wire fixing points will cause certain damage to the cable sheath under the action of wind. In serious cases, the cable may leak electricity at that location. Once the cable leaks electricity, it may cause very serious safety hazards such as electric shock. Utility Model Content

[0026] See also Figures 1 to 4 The utility model provides a technical solution: an insulation protection device for a tower crane cable, comprising: a protection tube 1 and a rotating plate 9, the protection tube 1 is made of a PVC insulating sleeve with a wall thickness of 4 mm, the rotating plate 9 is made of insulating material, the upper ends of the protection tube 1 and the rotating plate 9 are respectively provided with a connecting groove 1 2 and a connecting groove 2 10, a plug-in frame 3 is fixedly installed at the lower end of the protection tube 1, and an inlet and outlet are provided at one end of the protection tube 1 and the plug-in frame 3. When the rotating plate 9 is installed on the protection tube 1, the upper end of the rotating plate 9 is flush with the upper and lower ends of the protection tube 1, and at the same time, the connecting groove 2 10 and the connecting groove 1 2 are combined into a large plug-in groove, and the size of the plug-in groove is larger than the size of the plug-in frame 3.

[0027] A limiting groove 8 is provided on the side wall at one end of the inlet and outlet, and a hook 4 is fixedly installed on the side wall at the other end, through which the protective tube 1 can be fixedly installed on the standard section of the hanging tower.

[0028] One end of the rotating plate 9 is rotatably connected to the outer wall of the inlet and outlet, and a plurality of rotating shafts 5 are evenly and fixedly installed on the outer wall of the other end of the inlet and outlet. A plurality of cylinders 11 are evenly and fixedly installed on the side wall of one end of the rotating plate 9. By putting the cylinder 11 on the rotating shaft 5 from top to bottom, the rotating plate 9 can be rotated on one side of the protective tube 1, and the rotating plate 9 will not fall under the action of its own gravity. When the device is not needed, the rotating plate 9 can be pushed upward to be removed from the protective tube 1, which facilitates transportation and separate replacement of the rotating plate 9.

[0029] A rubber strip 12 is fixedly installed on the other end of the rotating plate 9. The size of the rubber strip 12 is slightly smaller than the size of the limiting groove 8. The rubber strip 12 is squeezed into the limiting groove 8 to fix the rotating plate 9 at the inlet and outlet. A cable routing area is formed between the rotating plate 9 and the protective tube 1 to protect the cable. At the same time, it is convenient to open the rotating plate 9 to ensure the separate inspection of each section of the protective tube 1.

[0030] A slide groove 6 is provided on the inner side of the upper end of the protective tube 1, and a partition plate 7 is provided on the inner end of the protective tube 1. The partition plate 7 is made of insulating material. The slide groove 6 and the partition plate 7 are both convex. One end of the partition plate 7 is slidably inserted into the slide groove 6 to divide the cable routing area into two parts, which is convenient for separating different cables and easy for maintenance.

[0031] The device is designed according to the current conventional tower crane standard section of 3m. Each standard section is divided into three horizontal bars: upper, middle and lower. The hook 4 on the back of the device is hung on the middle horizontal bar. The length of each standard section of the protective tube 1 is 1.5m (set to meet the 3m standard section length of the tower crane). The depth of the connecting groove 1 2, the connecting groove 2 10 and the plug-in frame 3 are all 50mm. Two adjacent protective tubes 1 are connected together by inserting the plug-in frame 3 into the plug-in groove, which ensures that only one hook 4 is set on the back to stabilize the device as a whole.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
