DETAILED DESCRIPTION

[0021] Due to the limited width and narrow space of underground coal mine tunnels, the overhead passenger device is often affected by the on-site conditions and cannot be installed in the conventional construction beam support method during the on-site installation process. Especially when arranged in the same tunnel as the belt conveyor, the drag beam installation method has the problem of mutual interference with the belt conveyor. Therefore, it is necessary to design a head frame for the overhead passenger device that is suitable for the actual needs of the underground, which requires solving the following problems:

[0022] 1. The head frame design must fully consider the equipment's safe operation factor to ensure the frame design strength;

[0023] 2. Fully integrate with the site to ensure the safe and normal operation of the equipment in the limited lane;

[0024] 3. The design of the head frame fully considers the transportation conditions up and down the well. Since the installation site of the overhead passenger device is often limited by the transportation channel, the head frame needs to be designed as an assembled structure and adopt a high-strength bolt connection assembly process;

[0025] 4. The design of the head frame should fully consider the size error of the monkey car head equipment. Since there is a certain error between the size of the equipment provided by the equipment manufacturer and the actual processing size, the matching size is designed to be adjustable, which greatly improves practicality;

[0026] 5. The design of the head frame should also take into account the need for equipment maintenance. A maintenance platform should be designed and installed on the basis of the frame to ensure the later maintenance of the equipment;

[0027] 6. The head frame design should fully consider the stability of the frame and use X-shaped diagonal bar support to ensure the stability of the equipment.

[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] As shown in the figure, a head frame for an overhead passenger device in a coal mine includes a symmetrically arranged front leg 1, a middle leg 2 and a rear leg 3, the tops of which are provided with a top beam 4, and both ends of the top beam 4 are provided with movable beams 5 for connecting the driving device of the overhead passenger device, and an X-shaped oblique tie bar 6 is provided between the front leg 1, the middle leg 2 and the rear leg 3 to improve the strength and reduce the deformation phenomenon caused by force. All parts are assembled and connected by high-strength bolts, and each part is symmetrical and interchangeable.

[0030] The front legs 1 are connected by transverse tie bars 7, and a maintenance platform is provided at the top of the movable beam 5. The maintenance platform is equipped with stairs, which can realize the free up and down movement of personnel, and facilitate the maintenance personnel to perform maintenance operations on the drive part.
