Embodiment 1

[0027] The overall installation process of the main shaft device of the friction hoist specifically includes the following steps:

[0028] According to the actual situation on site, pre-construction preparatory work should be carried out in advance: check the foundation, process and manufacture the pay-off frame, and release the wire at the point. Specific installation plan:

[0029] ① Determine the relative position of the equipment base according to the center line of the main shaft, the lifting center line and the design size of the drawing, and then use the level to measure the elevation of each foundation, make a record, and then grind the foundation to measure the foundation elevation of each foundation horn position;

[0030] ②After leveling and aligning the shim iron, use the crane to place the main shaft device as a whole on the foundation plane on which the wedge-shaped shim iron has been arranged, and use the wire pendant on the pay-off rack in the hoist machine roo...

Embodiment 2

[0032] The overall installation of the main shaft device of the floor-standing JKMD3.25×4ZⅢ multi-rope friction hoist in the main shaft of Baiheng Gold Mine, Muping District, Yantai City, the details of the equipment and materials used are shown in Table 1:

[0033] Table 1 Details of equipment and materials used

[0034] serial number name quantity unit 1 car crane 80T 1 set 2 steel wire Φ 0.5mm 2kg 3 level gauge DZS3-1 type 1 4 Theodolite J2-JDE 1 5 Frame level 200mm 2 units 6 saw bow 2 handles

[0035] The installation process specifically includes the following steps:

[0036] 1. Check the basics and set out

[0037] After the civil construction is completed, the construction unit will organize relevant units to conduct acceptance inspection. Check the foundation according to the drawing design requirements, observe whether the foundation size, elevation, and foundation holes meet the design re...

Abstract

The invention relates to the technical field of mine friction hoist installation, and specifically relates to a rapid installation process of a shaft device of a mine friction hoist, including the following process steps: checking the foundation, setting out wires; leveling the foundation, placing pad iron; and installing the shaft device. The installation process of the present invention optimizes the process of installing the hoist, and the overall installation and alignment of the main shaft and the shaft pillow seat saves construction time, labor and crane costs, and most importantly, it saves valuable time for the mine to go into production .

Description

technical field [0001] The invention relates to the technical field of installation of a mine friction hoist, in particular to a rapid installation process of a shaft device of a mine friction hoist. Background technique [0002] Multi-rope friction hoist is a large-scale mechanical transportation equipment used in deep shafts, shallow shafts and inclined shafts. It has high safety, thin wire rope diameter, small diameter of capstan wheel, light equipment weight, low power consumption and low price. Etc. The steel wire rope is put on the capstan wheel (friction wheel) of the hoist, and the hoisting container is suspended at both ends or the balance weight (hammer) is hung at one end. During operation, the friction between the friction liner of the capstan wheel and the steel wire rope is used to drive the steel wire rope to complete the container. up and down. The main components of the multi-rope friction hoist include the main shaft, the driving wheel, the main bearing, ...
