Abstract

The utility model relates to a device for taking and feeding a lining plate of a coal grinding machine, comprising a walking rack, a motor, and a speed reduction device. The device for taking and feeding a lining plate of a coal grinding machine is characterized in that a slipway is assembled on the walking rack. Chain wheels are hinged on two ends of the walking rack. Chains are assembled on the chain wheels on the two ends. Scraping plates are connected to the chains. A plurality of chain supporting wheels are arranged on the walking rack. The device for taking and feeding a lining plate of a coal grinding machine has the advantages that a lining plate is taken from a roller of a coal grinding machine, or the lining plate is inwards fed to realize mechanization. The device for taking and feeding a lining plate of a coal grinding machine has low labor intensity and a short construction period, and the work efficiency of the device for taking and feeding a lining plate of a coal grinding machine is greatly enhanced.

Description

Coal pulverizer liner plate fetching and sending devices

The utility model belongs to a kind of coal pulverizer maintenance auxiliary equipment, particularly a kind of coal pulverizer liner plate fetching and sending devices.

The low speed coal mill that in the thermal power plant, uses, through certain cycle of operation, its cylinder interior lining panel serious wear, replacing needs repairing, every liner plate weighs up to a hundred jin, amount to tens, rely on manually with liner plate at present, send from the helix tube of coal pulverizer cylinder, because the helix tube place is narrow, transmission liner plate inconvenience, and labour intensity is big, the cleaning long construction period.Equally, in cylinder, transmit new liner plate and also have as above problem.

The purpose of this utility model provides a kind of coal pulverizer liner plate fetching and sending devices, and what make liner plate fetches and delivers realization mechanization, reduces labor intensity, and shortens construction period.

The purpose of this utility model is achieved in that it comprises capable frame, motor and deceleration device, it is characterized in that: assemble slideway on the row frame, the hinged sprocket wheel in two ends of row frame, chain is assembled on the sprocket wheel of two ends, connect scraper plate on the chain, on the row frame several chain support rollers are set.

The utility model has the advantages that: take out liner plate or inwardly send into liner plate realization mechanization from the coal pulverizer cylinder, labour intensity is low, and short construction period increases substantially work efficiency.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the left part enlarged diagram of Fig. 1.

Fig. 4 is the A-A cutaway view of Fig. 1.

Fig. 5 is the user mode schematic diagram of table utility model.

See Fig. 1-4, concrete structure is as follows: the top slideway 2 that is fixedly connected of row frame 6, the two ends of row frame 6 are respectively by an axle connection sprocket wheel 1.Assembling motor 15 and deceleration device 14 in the row frame 6, deceleration device 14 and sprocket wheel 1 driving coupling.Chain 3 is sleeved on the sprocket wheel 1 at two ends.Equidistant hinged scraper plate 4 on the chain, scraper plate 4 is the L type, and both sides scraper plate 4 slides on two slideways 2, hangs naturally when scraper plate 4 slides when returning from the slideway two ends with chain.Both sides scraper plate 4 is fixed as one by connecting tube 16.Equidistant several chain support rollers 7 that is provided with on the frame 6 of being expert at play picking-up chain 3.Rotating connection contact roller 5 near the end of row frame 6.In order suitably to adjust the chain elasticity, being expert on the frame 6 to rotate by little axle 13 connects one and adjusts handle 8, rotates on the handle 8 to connect expansion tightening wheel 12, assembling cambered way 10 on the frame 6 of being expert at, connect an adjustment alignment pin 11 that on cambered way 10, slides on the handle 8, upwards pull the trigger piece 9 of handle, handle drives expansion tightening wheel 12 to top offset, and chain tension strengthens, otherwise pull downwards, chain tension reduces, and is transferred to certain correct position, tightens and adjusts alignment pin 11 location.

Operation principle: see Fig. 5, the helix tube 19 of the utility model from cylinder put in that its outer end gets final product by support member is fixing, present embodiment adopts the fork pin of fork truck 18 to fix.The inner of the present utility model single armed that is fixedly connected hangs 17, hangs without single armed that remove on the slideway with hand can also.During work, hang or the liner plate in the cylinder is placed on the slideway of the present utility model, carry out liner plate by scraper plate and slide,, thereby finished in the cylinder to outer transmission liner plate until the slideway end that is positioned at the cylinder outside at slideway with hand by single armed.If transmit new liner plate from outside to inside, operation principle is identical, and just direction is opposite.
