Abstract
The utility model provides a differential velocity hoist determining line laying length. One side of a coiling cylinder is connected with a counter counting rotation loops of a rotating shaft; length scales are evenly formed on a steel rope at intervals; line laying length of the steel rope can be calculated via the counter and the line laying length can be determined via the scale values on the steel rope; when the counter or the scales are destroyed, operation accuracy of the line laying length can be guaranteed via the scales or the counter; and different use conditions can be met via combination of the counter and the scales. The hoist is simply structured with convenient operation; and work efficiency can be improved and construction safety risks can be reduced.
Description
Technical field
The utility model relates to winch, particularly relates to a kind of differential winch of measuring unwrapping wire length.
Background technology
Winch is with the weight-lifting equipment of reel lay winding wire ropes or chain lifting or traction weight, is usually used among building engineering.Existing winch comprises reel and traction electric machine, and steel rope is housed on reel, and driven by motor reel is around its axle center rotation, and the steel rope in this process on reel is wrapped in gradually on reel or from reel and discharges gradually.
In modern architecture, the height of building is more and more higher, and winch is generally positioned on the ground outside building, and controlled by manual operation, but ground operating personal relies on new line visual observation, be difficult to determine the rise height of lifting thing, can only first lifting thing be hung to general position, then by cooperatively interacting with workmen upstairs, adjust gradually sling height.This causes complex operation, inefficiency, and lifting thing is in height constantly adjustment up and down in the air, has greatly improved its danger.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of differential winch of measuring unwrapping wire length, to determine easily sling height, increases work efficiency and construction safety.
The differential winch of mensuration unwrapping wire length described in the utility model, comprise reel, steel rope and motor, reel is connected with retarder by diff, on the axle that retarder is connected with motor, drg is installed, rotating shaft one side of reel is connected with the counting machine that calculates rotating shaft rotating cycle, on steel rope, compartment of terrain evenly indicates length scale, and one end of the hoisting heavy of steel rope is zero graduation.
The differential winch of mensuration unwrapping wire length described in the utility model, motor is by drg, diff and retarder governing speed, band movable reel is around its axle center rotation, in the time of reel rotation, drive counter works, counting machine calculates the rotating cycle of reel, meanwhile, steel rope is wrapped in release gradually on reel or from reel gradually according to the hand of rotation of reel, and can be observed the unwrapping wire length scale of steel rope.In construction work, the numerical value on counting machine under hoisting heavy postscript for the first time, after this this highly required unwrapping wire length is rotated the length of this numerical value for reel; On the other hand, also can write down the scale value on steel rope for the first time after hoisting heavy, after this required unwrapping wire length is this scale value.This winch can calculate by counting machine the unwrapping wire length of steel rope, also can measure unwrapping wire length by the scale value on steel rope, while equally damaging therein, can also guarantee by another sample the accuracy of operation, both cooperatively interact and can also meet different environments for use, for example construction environment dust is not easy to greatly check that counting machine screen can be by observing steel rope scale, if desired height is between steel rope two scales, steel rope mensuration is inaccurate can be guaranteed by counting machine.This winch is simple in structure, easy to operate, can increase work efficiency, and reduces construction safety risk.
Accompanying drawing explanation
Fig. 1 is the structural representation of measuring the differential winch of unwrapping wire length.
Fig. 2 is the structural representation of counting machine of measuring the differential winch of unwrapping wire length shown in Fig. 1.
Fig. 3 is the construction of wire rope schematic diagram of measuring the differential winch of unwrapping wire length shown in Fig. 1.
The specific embodiment
The differential winch of mensuration unwrapping wire length described in the utility model, comprise reel 1, steel rope 2 and motor 3, reel 1 is connected with retarder 5 by diff 4, on the axle that retarder 5 is connected with motor 3, drg 6 is installed, rotating shaft one side of reel 1 is connected with the counting machine 7 that calculates rotating shaft rotating cycle, on steel rope 2, compartment of terrain evenly indicates length scale, and one end of the hoisting heavy of steel rope 2 is zero graduation; Described counting machine 7 is mechanical counters of rope skipping use, comprises the axle core rotating with the rotating shaft of reel, and with the positive and negative hand of rotation of axle core, increases or reduce the dial plate of numerical value; On steel rope 2, adjacent scale value difference is three meters, and different scale value is denoted as different colors.
The differential winch of mensuration unwrapping wire length described in the utility model, counting machine adopts general rope skipping mechanical counter used, during forward, forward records numerical value, during reversion on the basis of this numerical value backwards calculation numerical value, in construction, when hoisting heavy hour counter starts to calculate by zero, the hour counter backwards calculation that declines after lifting final reset-to-zero scale, this counter structure is simple, work safety, operating personal only needs directly to observe numerical value, without carrying out extra calculating, convenient operation; Adjacent scale value is three meters, and the general story height that this length is general building is determined sling height and required floor during constructability, and different scale value adopts different colours to distinguish, and can greatly be convenient to visualizing operation, makes operation easier.
