Embodiment Construction

[0018] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 as shown, figure 1 It is a front view of a hydraulic hoist for coal mine underground loading and unloading equipment and materials proposed by the present invention. The hydraulic hoist for underground coal mine is composed of two parts: the boom and the hydraulic lifting frame. The boom includes a telescopic boom 1, a main boom 2 and a telescopic jack 3. The telescopic boom 1 is installed in the main boom 2 and forms a sliding pair with the main boom 2. One end of the telescopic jack 3 is hinged to the telescopic boom 1, and the other end is connected to the main boom. The boom 2 is hinged, and the expansion and contraction of the telescopic jack 3 can drive the telescopic arm 1 to expand and contract relative to the main boom 2. The hydraulic lifting frame is composed of a front ...

Abstract

The invention discloses a hydraulic hoisting machine used in an underground coal mine. The hydraulic hosting machine comprises a boom and a hydraulic lifting frame, wherein the boom is arranged on the hydraulic lifting frame; and the hydraulic hoisting machine is characterized in that the bottom comprises a main boom (2), a telescopic arm (1) forming a sliding pair together with the main boom and a telescopic jack (3); the telescopic arm (1), the main boom (2) and the telescopic jack (3) are coaxially arranged, one end of the telescopic arm (1) is sheathed in the main boom (2) and articulated with one end of the telescopic jack (3), a hanging hook is arranged at the other end of the telescopic arm (1), the telescopic jack (3) is arranged in the main boom (2), the other end of the telescopic jack (3) is articulated with the main boom (2), and the main boom (2) is arranged on the hydraulic lifting frame.

Description

technical field [0001] The invention belongs to a hydraulic hoisting machine, in particular to a hydraulic hoisting machine used for loading and unloading equipment and materials in coal mines. Background technique [0002] Due to the narrowness of the underground space of coal mines compared to the ground, it is impossible to use various hoisting equipment suitable for ground conditions, so only traditional manual lifting chains can be used to load and unload equipment and large materials, which makes the operation process of underground workers unsafe and labor-intensive. It is large and the efficiency is very low. Not only that, but mines with high gas content in underground coal mines also face a major safety hazard that may cause gas explosions due to inadvertent loading and unloading. Cases like this have happened before. Due to the constraints and restrictions of various conditions, the loading and unloading of equipment and materials in underground coal mines all a...
