Abstract
The utility model provides a maintenance turning-inside-out device for a medium speed wheel-type coal milling machine grinding roller and overcomes defects that many parts are disassembled during a maintenance process of an existing coal milling machine or normal operation of the coal milling machine is influenced due to deformation of a maintenance door. The maintenance turning-inside-out device for the medium speed wheel-type coal milling machine grinding roller comprises a fixing frame fixed on the outer surface of the lower portion of the machine casing, a movable frame arranged on the fixing frame through a vertical sliding channel mechanism, a lifting oil cylinder hinged between the fixing frame and the movable frame, a turning frame capable of vertically turning to extend to or recede from the machine casing, a turning roller oil cylinder with the lower end hinged on the movable frame, a turning connection rod hinged between the upper end of the turning roller oil cylinder and the turning frame, a milling roller installation fixing plate arranged on the turning frame, an oil conveying pipe connecting the oil cylinder with a pump station, and an oil-flow electric control unit. The maintenance turning-inside-out device for the medium speed wheel-type coal milling machine grinding roller has the advantages of overcoming the defect that dismounting the upper half parts of the coal milling machine during past maintenance causes large workload, huge consumable items and long construction period, and eliminating phenomenon of external leakage of coal powder caused by the fact that a milling roller moves out and is not loaded smoothly, and a door is not tightly closed due to the existed deformations of a door body and a door opening when the door body of the maintenance door bears the moving out of the milling rollers.
Description
Technical field
The invention belongs to mechanical field, be specifically related to large-scale with coal yard the wheeled coal pulverizer of middling speed of raw coal abrasive dust.
Background technology
The wheeled coal pulverizer of middling speed is in the past normally removed separator earlier when the maintenance grinding roller, disassembles loading frame and grinding roller then.After upwards hanging out loading frame, hang out grinding roller again, mill overhauls.Aforementioned maintenance mode need be set for this platform when removing separator, and the platform gross weight is about 30-50 tons, and is expensive big.And remove and to re-assembly after separator also relates to dismountings such as coal spout, flour extraction pipe, the wiring of thermal technology's measuring point, pneumatic element pipeline and reparation, relate to multidisciplinary cooperations such as machinery, electric, thermal technology.Overhauling once minimum 72 continuous throughout the twenty-four hour24s that will carry out can accomplish.
For improving the overhaul efficiency of coal pulverizer grinding roller; Minimizing occurred grinding roller is hung on the door body on the casing access door to the workload of disassembling of coal pulverizer before this, utilized bottle gouard moved by hands that grinding roller and door body level are together produced again; Though having reduced, this kind mode disassembles parts; But maintenance the time causes sinking of a body to cause a body itself or doorway distortion easily, because of door body, doorway are out of shape and can not normally close, can't accomplish service work and cause the phenomenon of serious leakage powder when reloading grinding roller.
Summary of the invention
The purpose of this invention is to provide the wheeled coal pulverizer grinding roller maintenance of a kind of middling speed and rout up device; Overcome exist in the existing coal pulverizer maintenance process to disassemble parts many; Consumable quantity is big, man-hour is long or the access door distortion, and it is not tight to close the door, and influences the deficiency of the normal operation of coal pulverizer.
Grinding roller of the present invention rout up device by the fixed mount that is fixed on the casing lower external face, be installed in adjustable shelf, two ends on the fixed mount with vertical slideway mechanism and be hinged on adjustable shelf hoist cylinder on fixed mount and the adjustable shelf respectively, be hinged on can vertically overturn rollover stand, the lower end of stretching into and withdraw from casing, adjustable shelf upper end and be hinged on turning over roller oil cylinder, be hinged on turning over roller oil cylinder axial location connecting rod, be hinged on the upset connecting rod that turns between roller oil cylinder upper end and the rollover stand between the upper end of turning over roller oil cylinder and the adjustable shelf on the adjustable shelf, rollover stand grinding roller mounting plate towards the configuration of grinding roller one side, connect the petroleum pipeline and the oil stream electric control unit composition of oil cylinder and pumping plant.
Good effect of the present invention is: realized that coal pulverizer when maintenance grinding roller supports and switching mechanism carries down and routs up and insert through access door in high strength, eliminated the shortcoming that workload strengthens, consume material is many, maintenance duration is long that the first half coal pulverizer that need disintegrate when in the past overhauling causes and with the door body of access door carry a grinding roller shift out and insert the body, the doorway that exist be out of shape cause grinding roller to shift out, packing into to have some setbacks and close the door does not sternly form the phenomenon that coal dust leaks.
Description of drawings
Fig. 1 is a side view of the present invention.
Fig. 2 is a front elevation of the present invention.
The specific embodiment
Consult Fig. 1, Fig. 2, at the lower external face welding fixed mount 2 of coal pulverizer casing 1.On the fixed mount 2 both sides frames vertical slot is arranged, the vertical slot on the frame of both sides is relative.Rectangle adjustable shelf 3 both sides are stretched in the vertical slot of fixed mount to be slidingly matched with fixed mount and are contained on the fixed mount.Install in the adjustable shelf both sides that the lower end is hinged on the fixed mount 2, the upper end is hinged on two adjustable shelf hoist cylinders 4 on the adjustable shelf 3.The rollover stand 5 of casing is stretched into and withdrawed to hinged can the upset of two hinges that is used in same horizontal level in the upper end of adjustable shelf 3.Two lower ends of turning over roller oil cylinder 6 arranged side by side are hinged on the lower end of adjustable shelf 3.Turn between hinge and the adjustable shelf of roller oil cylinder 6 upper ends and be hinged with the axial location connecting rod 7 that turns over roller oil cylinder 6.Turn over and also be hinged with the upset connecting rod 8 that connects rollover stand 5 on the hinge of roller oil cylinder 6 upper ends.Rollover stand 5 is towards grinding roller 10 1 sides configuration grinding roller mounting plate 9.Be connected petroleum pipeline between the oil nozzle of oil cylinder and the pumping plant.Oil stream electric control unit is installed in the system controller.
