An ore lifting device for shale gas development

Abstract

The invention discloses an ore lifting device for shale gas exploitation. The device comprises a lifting frame, columns are fixedly installed at the four corners of the upper surface of the lifting frame, side plates are installed at the portion, located at the inner sides of the columns, on the lifting frame, and a front door is rotatably connected to the side, close to the columns, on the lifting frame. According to the device, an auxiliary mechanism is adopted for assisting in conveying the lifting frame, the trouble of manually binding rock is overcome, and the problem that the rock is notwell bound in the lifting process is solved; the rock to be lifted can be weighed by a weighing plate, staff conveniently know the weight of the rock at any time, and the unnecessary troubles causedwhen the weight of the rock is too large and exceeds the lifting range are avoided; the side plates of the lifting frame are protected by buffering springs and buffering pads, the problem that the side plates are impacted by the rack in the lifting process and deform is overcome, the use quality of the lifting frame is guaranteed, and the lifting safety and stability are also improved.

Description

technical field [0001] The invention relates to the technical field of shale gas exploitation, in particular to an ore lifting device for shale gas exploitation. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale-dominated reservoir rock series. It is continuously generated biochemical gas, thermogenic gas or a mixture of both, and can exist in natural fractures in a free state. It exists in the surface of kerogen and clay particles in an adsorbed state, and a very small amount is stored in kerogen and asphaltene in a dissolved state. The proportion of free gas is generally 20% to 85%. [0003] During the mining of shale gas, rocks need to be crushed and removed. During the rock removal process, the manual operation is too cumbersome and the efficiency is low. Therefore, a lifting device is required. Currently, the ore lifting device is used to trap the ore It is too cumbersome and inconvenient to operate. At the s...

Problems solved by technology

[0003] During the mining of shale gas, rocks need to be crushed and removed. During the rock removal process, the manual operation is too cumbersome and the efficiency is low. Therefore, a lifting device is required. Currently, the ore lifting device is used to trap the ore It is too cumbersome and inconvenient to operate. At the same time, the weight of the ore is not well understood, which will easily affect the stability and safety of the lifting. Moreover, when the ore is lifted, the safety protection is not perfect. Therefore, those skilled in the art provide a shale gas Develop ore hoisting device to solve the problems raised in the above-mentioned background technology
