[0002] With the acceleration of the progress of mine construction projects, there are more and more deep shaft projects. The installation work in the shaft is dangerous and difficult. Therefore, it is necessary to set up a working platform in the shaft to facilitate the operators to work in the shaft. At present, most of the operations in the mine still use traditional scaffolding or cages. The scaffolding is time-consuming and labor-intensive, and it is more difficult for operators to move when working at different heights. When the cage is used as a working platform for operation, it is inconvenient for operators to operate in the cage due to the small space of the cage. The scaffolding or cage is used as a working platform, but the cage is time-consuming and labor-intensive, and the efficiency is low. Utility Model Content

[0019] The utility model is described in detail below with reference to the accompanying drawings:

[0020] like Figure 1-4 The lifting platform 5 is a kind of internal working platform of a shaft, which includes a bracket 2 arranged at the top of the shaft 1, and a winch 3 is arranged on the bracket 2. The winch 3 can adopt the existing conventional winch. A wire rope 4 is connected to the winch 3, and a horizontally arranged movable platform 5 is connected to the bottom of the wire rope 4. The movable platform 5 can move up and down in the shaft 1 under the pulling of the wire rope 4. The operator can stand on the movable platform 5 to perform relevant operations in the shaft, and adjust the working position through the movable platform 5 to perform operations at different heights in the shaft. In order to maintain stability during the operation, a vertically arranged guide rod 6 is provided at the lower part of the bracket 1, and the bottom end of the guide rod 6 is fixed to the bottom of the shaft 1, and the guide rod 6 is located in the middle of the movable platform 5. A sleeve 7 corresponding to the guide rod 6 is provided on the movable platform 1, and the sleeve 7 is sleeved on the guide rod 6. The sleeve 7 can make the movable platform 5 stable and not shaken during the up and down movement, and the bottom end of the wire rope 4 is connected to the middle of the movable platform 5.

[0021] In order to prevent the operator from walking on the movable platform 5 during the operation of the movable platform 5, especially when the operator moves to the edge of the movable platform 5, which makes the center of gravity of the movable platform 5 unstable and overturns, 3-5 stabilizing members 8 for preventing the movable platform 5 from overturning are provided at the edge of the movable platform 5. In this embodiment, four stabilizing members 8 are provided. The stabilizing member 8 includes a vertically arranged stabilizing rod 801, an upper supporting wheel 802 is provided at the top of the stabilizing rod 801, and a lower supporting wheel 803 is provided at the bottom. The upper supporting wheel 802 is located on the upper side of the movable platform 5 and abuts against the inner wall of the shaft 1, and the lower supporting wheel 802 is located on the lower side of the movable platform 5 and also abuts against the inner wall of the shaft 1. The support of the stabilizing member 8 can effectively prevent the movable platform 5 from overturning in the shaft 1. In addition, a protective fence 9 is provided at the edge of the movable platform 5.

[0022] The usage of the utility model is as follows:

[0023] When in use, the height of the movable platform 5 is raised by the winch 3, so that the movable platform 5 is located near the top of the shaft 1, and then the operator can enter the movable platform 5 from the wellhead of the shaft 1, and then release the wire rope 4 through the winch 3 to move the movable platform 5 to a corresponding height, so that the operator can perform corresponding operations in the shaft 1. When the operator walks and moves on the movable platform 5, the stabilizing member 8 on the movable platform 5 can support the edge of the movable platform 5, effectively preventing the center of gravity shift on the movable platform 5 from causing the movable platform 5 to flip over, ensuring safety and reliability, and preventing safety accidents. In addition, during operation, the height of the movable platform 5 can be adjusted by the winch 3, which is convenient and quick to use. Compared with the cage movable platform 5, the operating area is large and there is no side wall obstruction, which can make the operation more convenient.
