Problems solved by technology

[0002] At present, in the fully-mechanized mining equipment for underground coal mining in coal mines, in order to pass through the transfer machine, the human ladders used in the existing transfer machines are all fixed and non-adjustable. Due to the variability of underground mining conditions, fixed human ladders are common. impractical
Especially in the top-coal caving equipment, the equipment cannot guarantee the particle size of the coal blocks on the rear conveyor. When a large coal block passes through, if the traditional ladder is used, it will collide with the coal block, thus causing the ladder to be damaged.

Embodiment Construction

[0011] Such as figure 1 , figure 2 Shown full-enclosed reloading machine tail is with retractable people's ladder, comprises main structures such as people's ladder 1, support 2, support 3, fixed frame 4, oil cylinder 5, slide frame 6.

[0012] image 3 Shown is a schematic diagram of the state of the carriage extended after oil is supplied to the oil cylinder. At this time, the oil cylinder is extended by operating the valve group to extend the oil cylinder, which drives the carriage to extend across the loader and allow the staff to pass. After the worker passes through, operate the control valve to retract the oil cylinder and drive the carriage to retract.

[0013] Figure 4 Shown is a traditional ladder structure, one end is fixed to the baffle side of the unloading section of the reloader, and the other side has no support, and it freely crosses the coal flow of the reloader to connect the two sides. The structure is simple and easy to manufacture, but it is poor in ...

Abstract

The invention relates to the technical field of stage loaders in fully-mechanized coal mining devices for coal mining under coal mine wells, in particular to a telescopic ladder used in a stage loader tail. The telescopic ladder is characterized in that compared with a traditional ladder, the ladder is mainly composed of a ladder body (1), a supporting frame (2), a support (3), a fixing frame (4), an oil cylinder (5), a sliding frame (6) and the like. In an existing stage loader, an adopted ladder is fixed and nonadjustable; and due to the variability of the underground mining condition, granularity of coal briquettes at a rear conveying machine cannot be guaranteed especially when the ladder is put into a top coal device. By means of the telescopic ladder for the stage loader tail, when large coal briquettes pass, the ladder can be withdrawn timely, collision is avoided, and thus large blocks of coal can pass.

Description

technical field [0001] The invention relates to the technical field of a loader in fully mechanized mining equipment for underground coal mining in coal mines, in particular to a retractable ladder for the tail of the loader. Background technique [0002] At present, in the fully-mechanized mining equipment for underground coal mining in coal mines, in order to pass through the transfer machine, the human ladders used in the existing transfer machines are all fixed and non-adjustable. Due to the variability of underground mining conditions, fixed human ladders are common. of impracticality. Especially in the top coal caving equipment, the equipment cannot guarantee the particle size of the coal blocks on the rear conveyor. When a large coal block passes through, if a traditional man ladder is used, it will collide with the coal block, thus causing the man ladder to be damaged. Contents of the invention [0003] The purpose of the present invention is to provide a kind of ...
