Installation and removal crane for mining devices

Abstract

The invention discloses an installation and removal crane for mining devices, comprising a hoisting hook, and a support part, a rotating part, a hoisting part and a moving part, wherein the support part is installed and matched with a chute; the rotating part is hinged with the support part and drives the hoisting hook to rotate; the hoisting part is hinged with the support part and drives the hoisting hook to lift; and the moving part drives the hoisting hook to move. The installation and removal crane has the advantages that: the crane leads mechanization to be realized for both installation and removal of coal mine equipment, reduces labor intensity, improves work efficiency and reduces accidents; besides, the crane has large hoisting tonnage, can not only be used for installation of chutes but also installation of large devices such as hydraulic brackets and the like, has the advantages of strong universality, simple structure, easiness for installation and maintenance, easiness for carrying, high working efficiency when working and small workforce; and a working face chute can be installed at least 15 days in advance.

Description

technical field [0001] The invention relates to the technical field of mining heddle machines and supporting equipment, in particular to a mining equipment safety and withdrawal crane. Background technique [0002] Since the 1970s and 1980s, my country began to introduce fully-mechanized mining equipment for mining. Up to now, the annual output of fully-mechanized mining has exceeded 300 million tons. However, the installation and dismantling of the comprehensive machine equipment adopts the cumbersome physical installation process of manpower dragging and lifting bars and manual hoist lifting, which takes a long time to install a working face and the labor intensity of workers is high. The patent application whose publication number is CN101537561B and whose application name is "lifting and installing vehicle for fully mechanized mining equipment" discloses a device used for the installation of complete mechanized mining equipment. This device is used in the installation of...

However, the installation and dismantling of the helical machine equipment adopts the cumbersome physical installation process of manpower dragging and lifting the bar and manual hoist lifting. It takes a long time to install a working surface and the labor intensity of the workers is high.

The patent application whose publication number is CN101537561B and whose application name is "lifting and installing vehicle for fully mechanized mining equipment" discloses a device used for the installation of complete mechanized mining equipment. This device is used in the installation of fully mechanized mining face scraper conveyor , the middle trough can be hoisted and unloaded from the flatbed truck, transported to the installation location, assembled into a coal trough, hoisted and installed the head and tail equipment of the scraper conveyor; it has a walking device, which does not require vehicle traction when moving; the beam , The longitudinal beam and the column are connected by bolts, which can be disassembled and combined; there is a hydraulic cylinder hinged in the middle of the beam, which is suitable for the asynchronous movement of the left and right beams; the telescopic ceiling column is connected to the beam and above the hydraulic telescopic column. The inner sleeve of the telescopic ceiling column can be fixed on the ceiling of the coal mining face, which has the advantages of fast installation speed, high safety and convenient movement, but this device is specially designed for the installation of the scraper conveyor in the fully mechanized mining face , poor interchangeability
