The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, the technical solution adopted in the utility model is: a kind of dish formula air winch of stopping, mainly comprise distribution assembly 1, the housing piston assembly, speed reduction gearing 4, reel 5, a brake assembly 7 and a left side, right support, described reel 5 is arranged between the two stands of the left and right sides, brake assembly 7 is arranged on the outside of left socle, this brake assembly 7 is the disk type brake structure, distribution assembly 1 is arranged in the housing piston assembly forms motor assembly, the motor assembly device is in the outside of right support, distribution assembly 1 is connected with brake assembly 7 by the tracheae line, described speed reduction gearing 4 is arranged on reel 5 inside and is connected with the motor assembly output shaft, is provided with hand-operated brake 3 assemblies between the reel 5 wheel rims outside and right support.Speed reduction gearing 4 in the present embodiment is a planetary gear speed reducing mechanism.
Valve body one side of described distribution assembly 1 is provided with admission port, valve body admission port below is provided with valve seat, the air flue of valve seat bottom is connected with distributing valve, air flue upper body one side of distributing valve is provided with an air extractor duct, air extractor duct connects the tracheae line, distribution assembly 1 is connected with brake assembly 7 by the tracheae line, valve body one side of distributing valve also has an admission port to be connected with brake assembly 7, during stopping brake, brake cylinder i.e. back gas lid 11 is got back to the distributing valve discharge with the spring platen 13 anterior pressurized airs of protruding in the positions by the tracheae line.
Described disk type brake brake assembly 7 is the normally closed structure, comprise back gas lid 11, platen 12, spring, spring platen 13, Brake Block 14, internally toothed annulus 15 and friction lining, described friction lining comprises moving, the static friction sheet, movable friction plate 17 is connected with the output shaft of motor assembly by female splines, static friction sheet 16 is arranged on movable friction plate 17 outsides, platen 12 is close to the outside of static friction sheet 16, platen 12 all becomes hollow annular with the middle part of back gas lid 11, hole size unanimity in them, back gas lid 11 is fixedly connected on platen 12 front portions, form hollow tubular, spring platen 13 is the anterior ring-type of protruding, its front portion is arranged in the back gas lid 11, spring platen 13 is flexible connection with back gas lid 11, and between is provided with sealing member, spring platen 13 outer rims are captiveed joint with internally toothed annulus 15, internally toothed annulus 15 is captiveed joint with Brake Block 14, and is moving, the static friction sheet is arranged in the internally toothed annulus 15, and Brake Block 14 rear sides are captiveed joint with left socle.After the brake assembly 7 logical pressurized airs, platen 12 and back gas lid 11 can outwards move, spring platen 13 and back gas lid 11 actual fully enclosed cylinder barrel and the piston actions of forming.
Disk type brake mechanism in the present embodiment is in the form of piston, can also be air sac, and braking effect and present embodiment are basic identical.
The utility model winch is under not ventilation or dead ship condition, and platen 12 clamps dynamic and static friction lining with Brake Block 14, is in braking state.When connecting source of the gas, source of the gas enters motor assembly, and operating handle just can be realized lifting, parking or the decline work of winch, and this moment, pressurized air entered distribution assembly 1, pulls operating handle control reel 5 and realizes forward and backward; Simultaneously, pressurized air is by being communicated with the back gas lid 11 of brake assembly 7 with sidepiece air extractor duct bonded assembly tracheae line.Because back gas lid 11, spring platen 13, Brake Block 14 and dynamic and static friction lining are formed a fully enclosed air chamber, when pressurized air is imported in this air chamber by tracheae after, because spring platen 13, Brake Block 14 and terminal pad are what captive joint, gas in the air chamber just can promote the 11 outwards motions of back gas lid, back gas lid 11 again with platen 12 for captiveing joint, so platen 12 againsts the force of the spring outwards move, platen 12 leaves friction lining, remove brake, realize the rotating of capstan drum 5.When winch when dead ship condition or winch are died state, distributing valve also stops simultaneously to brake assembly 7 air inlets, just inwardly motion under action of the spring of platen 12 makes platen 12 pressing friction sheets, reel 5 can not rotate, air winch is not worked.Air winch of the present utility model is when forward and backward turns round, and brake is unclamped automatically; When air winch stopped or source of the gas is died, brake was automatically locked.Therefore, braking mechanism is automation, than other structure air winchs, and hommization more, safe and reliable, simple to operate, reliability improves greatly.
The utlity model has rational in infrastructurely, compact, security is good, and reliability is strong, and volume is little, noise is low, the transmission efficiency high.
