[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is connected section by section and is used to lift raw materials for construction such as steel bars, concrete, steel pipes, etc. Operators need to inspect and maintain the tower crane regularly when it is in use.

[0003] In this regard, China applied for patent number: CN202122159219.4, which discloses a safety protection device for tower crane maintenance, including a transverse truss and a vertical truss, wherein the transverse truss and the vertical truss constitute the main body of the tower crane, and a lifting runway is fixed on the side of the vertical truss, and two lifting runways are arranged, which are symmetrically distributed front and back, and slide grooves are provided in the vertical direction on the opposite sides of the two lifting runways, and a lift is slidably installed between the lifting runways, and a fixed block is fixed on the side of the vertical truss. In short, the technical solution of the application utilizes a coherent and compact structure to solve the problem that during the use of the lift on the traditional tower crane, the staff usually closes and locks the door of the lift to achieve the greatest protection of the staff's safety, but when the lift fails or the rope for pulling the lift breaks, there are no additional protective measures and the safety of the staff is difficult to guarantee.

[0004] This protective device can move the staff up and down by setting a safety rope, but it cannot protect the staff when inspecting the boom, because the lifting of the goods is mainly achieved by the lifting mechanism installed on the boom, so it is particularly important to inspect the boom.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a tower crane maintenance and protection device. Utility Model Content

[0010] Preferably, the fixing column is installed vertically and the steel wire rope is installed horizontally.

[0011] Preferably, one end of the steel wire rope is fixedly connected to the outer wall of the working room, and two groups of the steel wire rope are provided, and the two groups of the steel wire rope are respectively arranged on both sides of the boom.

[0012] Preferably, the shield is installed just above the steel wire rope.

[0013] Preferably, the hook cooperates with the steel wire rope.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, when it is necessary to inspect and repair the boom, the safety clothing is taken out of the box, the safety clothing is put on the body, and the hook is hooked on the wire rope. When the staff performs inspection and repair work on the boom, the hook can move on the wire rope, which can protect the staff without affecting the normal activities of the staff on the boom, making the inspection and repair work on the boom safer. At the same time, two groups of wire ropes are provided, and the two groups of wire ropes are respectively located on both sides of the boom. The hooks can be installed on the corresponding wire ropes according to the needs of use, avoiding the need to climb back and forth on the boom and increase safety hazards.
