The utility model puffer, it has main shaft device, depth indicator, limit switch, speed limiting switch, base, control desk, limiting device and electrical motor is characterized in that: main shaft device is mainly by eccentric shaft, reel, and floating disc lacks tooth difference deceleration part, and bearing seat is formed; End is provided with caliper-type disc damper brake and speed governing lock about reel; Adopt yoke plate formula coupler to connect between eccentric shaft and the motor; Control desk liquid collecting pressing system, electric part, actuating element are in a casing, but distance control.

The utility model puffer, the few tooth difference deceleration part of floating disc places in the reel, reel is bearing on the Y-axis bearing, the reel right-hand member is provided with the braking wheel disc, left end is provided with the speed governing wheel disc, timber lining is housed to reduce steel rope abrasion on the reel, and the reel barrel shell connects by the internally toothed annulus of bolt with few tooth difference deceleration part, coaxial decentraction between floating disc on the eccentric shaft is taken turns with few tooth difference, motor is passed to external gear to power through coupler by eccentric shaft.Caliper-type disc damper brake and speed governing lock are made up of oil cylinder, support, gudgeon plate, lock seat, brake shoe, and the speed governing lock is open in usual, and damper brake is a normally closed.The linking-board type coupler is formed by the connection of plurality of thin bolt of strap plate by two triangle shaft coupling pieces, is hexagon.

The utility model puffer has following advantage:

1. realize the remote centralized operation of winch, convenient and safe;

2. speed governing lock and damper brake are by control desk HYDRAULIC CONTROL SYSTEM and realization interlock;

3. the service braking of damper brake and safety arrestment unite two into one;

4. overwinding-proof is installed on the depth indicator, the restriction signal switch that puts in place, can realize the winch overtravel protection, the speed-limiting protection and the signal prompt that puts in place;

5. built-in few tooth difference drive mechanism makes winch can realize mechanical stepless speed change;

But 6. emergency braking, winch is safe and reliable, the efficient height;

7. compact integral structure is reasonable, in light weight, and floor area is little.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

The utility model puffer is shown in Figure 1: by main shaft device 6, and coupler 3, speed governing lock 4, depth indicator 5, damper brake 7, electrical motor 2, control desk 1, base 8, compositions such as centrifugal speed limiter.Shown in Figure 2: main shaft device 6 is built-in two teeth difference floating disc type output mechanism, mainly by eccentric main axis 6-6, reel 6-5, floating disc 6-7, two teeth difference deceleration part external gear 6-3, internally toothed annulus 6-2, bearing seat 6-1 forms, coaxial decentraction between floating disc 6-7 on the eccentric shaft 6-6 and the external gear 6-3, the few tooth difference deceleration part of floating disc places in the reel 6-5, and reel 6-5 barrel shell connects with internally toothed annulus 6-2 by bolt; Timber lining 6-4 is housed, to reduce steel rope abrasion on the reel 6-5; Reel 6-5 left end is provided with speed governing wheel disc 6-8, and right-hand member is provided with braking wheel disc 6-9.Main motor 2 is passed to external gear 6-3 to power through coupler 3 by eccentric shaft 6-6, by floating disc 6-7, bearing pin, speed disk 6-8, other adds speed governing lock 4 and forms speed regulation device, by speed regulation device power, speed are passed to internally toothed annulus 6-2, at last to reel 6-5.End is provided with about reel 6-5 speed governing lock 4 and damper brake 7 are caliper-type disc, adopt fluid control mechanical governing or braking, oil cylinder 9, pincers type support 10, big gudgeon plate 11, lock seat 12, microtia axillare 13, brake shoe 14, brake shoe seat 15 compositions such as grade.Establish two pairs of hydraulic disk speed governing locks 3 in speed disk 6-8 both sides, speed governing lock 3 is open in usual, and during the no oil pressure of oil cylinder 9, in-oil cylinder belleville spring promotes piston rod, by pincerlike support 10 brake shoe 14 is separated with speed disk 6-8; Give when pressing in the oil cylinder 9, oil pressure promotes the motion of piston rod compact disc spring, brake shoe 14 contacts with speed disk 6-8, apply resisting moment, the floating disc 6-7 of speed disk 6-8 and tooth difference deceleration part combines as a whole, thereby by floating disc 6-7, bearing pin is passed to resisting moment the driving wheel external gear 6-3 of two teeth difference deceleration part, realize changing reel 6-5, promptly the winch operating speed reaches the speed governing purpose.Be provided with two pairs of damper brakes 7 in reel brake disc 6-9 both sides, its structure is identical with the speed governing lock, and only the oil cylinder sense of motion is opposite, is used for the service braking of winch running, safety arrestment, emergency braking.Damper brake 7 is a normally closed, and when not having pressure or residual voltage, in-oil cylinder disk spring promotes pincerlike support 9, elastic force is amplified twice affact and hold brake disc 6-9 on the brake shoe 14 tightly, the braking winch is given when pressing in the oil cylinder 9, the dish spring is compressed, and damper brake 7 unclamps, and winch closes tube and can turn round.Planer-type depth indicator 5 is adopted in the top of reel, the deceleration sender that is used to put in place, overwinding-proof, speed limit travel switch are housed on it, electric bell one end also is equipped with centrifugal speed limiter, drum speed is passed to depth indicator 5 leading screws by sprocket wheel, chain, drive pointer by nut again and move demonstration lifting container position along direction board, the fast sender that puts in place, the overwinding-proof travel switch is worked by the nut collision, and limitation travel switch is worked by the centrifugal speed limiter collision.Connecting of eccentric shaft 6-6 and motor 2 with linking-board type coupler 3, Fig. 4, shown in Figure 5, it is by two triangle shaft coupling piece 3-2,3-4, by plurality of thin connecting panel 3-3, bolt 3-1 connects and forms, and is hexagon, and volume is little, and damping characteristics is arranged.Whole brake system is set up a control desk 1 separately, control desk 1 liquid collecting pressing system, electric part, actuating element in a casing, compact conformation, volume is little, at a distance the centralized operation winch.
