The open end of the positioning cylinder abuts against the end face of the central cylinder of the steel wire reel, and the closed end of the positioning cylinder is abutted by the operation nut.

[0006] As a preferred scheme of the above installation tool, a gasket is further sleeved on the installation screw rod, and the gasket is located between the operation nut and the end plate of the positioning cylinder.

[0007] As a preferred scheme of the above installation tool, an external hexagonal operation head is arranged at one end of the installation screw rod away from the output shaft of the reducer.

[0008] As a preferred scheme of the above installation tool, the installation screw rod and the positioning cylinder are both coaxially arranged with the output shaft of the reducer.

[0009] The utility model has the following advantages compared with the prior art:

[0010] An installation tool for a steel wire reel provided by the present utility model is connected to a threaded hole of a reducer output shaft by arranging an installation screw rod, and the open end of a positioning cylinder sleeved on the installation screw rod presses against the central cylindrical end face of the steel wire reel. By rotating an operation nut, the steel wire reel can be pressed by the positioning cylinder to move towards the reducer output shaft, thereby realizing the installation of the steel wire reel and the reducer output shaft. The whole installation process is convenient, fast, time-saving and labor-saving, improves the operation efficiency, makes the replacement operation of the reducer more convenient, and reduces the operation difficulty and intensity of maintenance personnel.

[0016] The following is a detailed description of the embodiments of the present utility model. The embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0017] See Figures 1 to 4, this embodiment discloses an installation tool for a wire reel. A central cylinder 2 is provided inside the wire reel 1. The central cylinder 2 of the wire reel 1 is installed on the output shaft 3 of the reducer by a tight fit method, and the transmission connection between the two is achieved by a key connection method. The installation tool includes a positioning cylinder 4, an installation screw rod 5, and an operation nut 6. One end of the positioning cylinder 4 is a closed end and the other end is an open end. The closed end of the positioning cylinder 4 is closed by an end plate 7. A perforation 8 is opened in the center of the end plate 7 of the positioning cylinder 4. The positioning cylinder 4 is sleeved on the installation screw rod 5 through the perforation 8 of the end plate 7. The operation nut 6 is threadedly sleeved on the installation screw rod 5 and is located outside the end plate 7 of the positioning cylinder 4. One end of the installation screw rod 5 is threadedly connected to the threaded hole at the end of the output shaft 3 of the reducer. An external hexagonal operation head 9 is provided at the end of the installation screw rod 5 away from the output shaft 3 of the reducer, which is convenient for the installation screw rod 5 to cooperate with a wrench for rotation operation. The installation screw rod 5 and the positioning cylinder 4 are both coaxially arranged with the output shaft 3 of the reducer. The open end of the positioning cylinder 4 abuts against the end face of the central cylinder 2 of the wire reel 1, and the closed end of the positioning cylinder 4 is pressed by the operation nut 6. A gasket 10 is also sleeved on the installation screw rod 5, and the gasket 10 is located between the operation nut 6 and the end plate 7 of the positioning cylinder 4.

[0018] When replacing the load platform reducer of the stacker in the cigarette box high-rise warehouse, after the replacement is completed, the disassembled wire reel 1 needs to be reinstalled on the output shaft 3 of the replaced reducer. During installation, first, the operation nut 6, the gasket 10, and the positioning cylinder 4 are sequentially sleeved on the installation screw rod 5, and the open end of the positioning cylinder 4 is abutted against the end face of the central cylinder 2 of the wire reel 1. Use a wrench to rotate the external hexagonal operation head 9 of the installation screw rod 5, so that the inner end of the installation screw rod 5 is screwed into the threaded hole at the end of the output shaft 3 of the reducer, realizing the fixed connection between the installation screw rod 5 and the output shaft 3 of the reducer. Then use a wrench to rotate the operation nut 6, so that the operation nut 6 moves towards the output shaft 3 of the reducer, thereby driving the positioning cylinder 4 to move towards the output shaft 3 of the reducer, and then the positioning cylinder 4 pushes the wire reel 1 to move towards the output shaft 3 of the reducer, so as to install the wire reel 1 on the output shaft 3 of the reducer. The entire installation process is convenient, fast, time-saving and labor-saving, improving the operation efficiency, making the replacement operation of the reducer more convenient, and reducing the operation difficulty and intensity of the maintenance personnel.

[0019] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention.
