Abstract
The utility model relates to a maintenance and mounting tool for a coal mine machine, particularly to a disassembly-assembly device for a roller of the coal mine machine, which solves the technical problems that the disassembly and assembly of the roller has low efficiency and is not safe. The disassembly-assembly device comprises a large frame, wherein a roller seat is arranged in the large frame, and a guiding seat is arranged on one side of the large frame; and a side top jack is arranged on the guiding seat, and a roller pressing jack is arranged above the large frame. Compared with the prior art, the utility model has the advantages that a set of devices, i.e. the large frame for fixing the roller and the jacks for disassembling and assembling a shaft, are designed to solve the shaft assembly and disassembly difficulty in roller maintenance, and the jacks are used to replace manual labor for shaft disassembly and assembly, so that the work efficiency, safety and mounting quality are all improved.
Description
Technical field
The utility model relates to a kind of coal machine examination and repaiies erecting tools, is specially a kind of coal mine machinery cylinder attaching/detaching apparatus.
Background technology
At present, in the various machineries in colliery, cylinder is a kind of more common assembly, and for example feed belt, winch etc. are gone up and widely applied.Method for various cylinder dismounting axles all is to adopt big hammer-harden spooling head, little by little axle is withdrawn or is loaded in bearing, and the drawback of doing like this has several: 1, be not easy operation, worker's labour intensity height, inefficiency; 2, be fixing not firm, safety coefficient is low; 3, be to cause spool a two ends distortion and a cracking easily, also cause the bending shaft distortion easily.
Summary of the invention
The utility model is low for the efficient that exists in the installation and removal that solve cylinder, uneasy congruent technical problem and a kind of coal mine machinery cylinder attaching/detaching apparatus is provided.
The utility model is realized by following technical scheme, a kind of coal mine machinery cylinder attaching/detaching apparatus, and structure comprises big frame, in big frame, be provided with roller seat, side at big frame is provided with guide holder, and it is very heavy that guide holder is provided with the side top, and it is very heavy to be provided with pressure roller above big frame.
The utility model is mainly used in the dismounting and the installation of belt feeder cylinder and various puffer cylinders.Compared with prior art, the utility model is at the difficulty of maintenance dismounting axle during cylinder, and the device of the big frame by designing a cover resting barrel and the jack of dismounting axle utilizes very heavy replacement manpower to carry out the dismounting and the installation of axle, improved operating efficiency, security and installation quality.
Description of drawings
Fig. 1 is the schematic diagram of cylinder attaching/detaching apparatus described in the utility model.
Among the figure: 1-guide holder, big of 2-, 3-pressure roller are very heavy, 4-cylinder, 5-roller seat, 6-axle, 7-side top are very heavy.
The specific embodiment
As schematically shown in Figure 1, a kind of coal mine machinery cylinder attaching/detaching apparatus, structure comprises big frame 2, is being provided with roller seat 5 in big frame 2, is provided with guide holder 1 in a side of big frame 2, guide holder 1 is provided with side and pushes up very heavyly 7, is provided with pressure roller very heavy 3 above big frame 2.
Cylinder is contained in the roller seat, puts into big frame after fixing; According to the position of different drum shafts, adjust the very heavy height in side top, make its with the axle that needs demolition, installation in the same way, and side is pushed up very heavy guide holder fixes; Stretch out downwards pressure roller is very heavy, push down the cylinder in the big frame, guarantee that cylinder can not produce displacement when the very heavy action in side top, avoid because the side top very heavy with spool the fortuitous event that rolls of the cylinder that causes inadequately of axiality; After confirming fixation, very heavy the stretching out in side top heads into axle or eject cylinder.
