Abstract
A kind of can survey line long winch, 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, calculate the unwrapping wire length of steel rope by counting machine, also can measure unwrapping wire length by the scale value on steel rope, while equally damage therein, can also ensure by another sample the accuracy of operation, both cooperatively interact and can also meet different environments for use, this winch is simple in structure, easy to operate, can increase work efficiency, reduce construction safety risk.
Description
Technical field
The utility model relates to winch, particularly relate to a kind of can survey line long winch.
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 by manual operation control, 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; In prior art, conventionally adopt electronic counting system and cause having the problem that cannot use while power failure.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can survey line long winch, to determine easily sling height, increase work efficiency and construction safety.
The winch of mensuration unwrapping wire length described in the utility model, comprise rack-mounted driving engine, reel and there is secondary or the driving device of above step-down ratio, rotating shaft one side of reel is also connected with the counting machine that calculates rotating shaft rotating cycle, steel rope compartment of terrain on reel evenly indicates length scale, and one end of the hoisting heavy of steel rope is zero graduation.
The winch of mensuration unwrapping wire length described in the utility model, driven by engine reel is around its axle center rotation, when reel rotation, drive counter works, counting machine calculates the rotating cycle of reel, simultaneously, steel rope is wrapped in gradually on reel or from reel and discharges 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, the length that after this this highly required unwrapping wire length is rotated this numerical value for reel; On the other hand, also can write down for the first time the scale value on steel rope 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 damage therein, can also ensure 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 ensured by counting machine.This winch is simple in structure, easy to operate, can increase work efficiency, and reduces construction safety risk; Even if having a power failure, do not affect construction operation yet, boost productivity.

Detailed description of the invention
A kind of can survey line long winch, comprise driving engine 3, the reel 2 being arranged in frame 1 and there is secondary or the driving device of above step-down ratio 4, rotating shaft one side of reel 2 is also connected with the counting machine 5 that calculates rotating shaft rotating cycle, steel rope 6 compartment of terrains on reel 2 evenly indicate length scale, and one end of the hoisting heavy of steel rope 6 is zero graduation; Driving device 4 is double reduction chain wheel driving mechanism, comprise the second stage speed reduction gearing of first order acceleration mechanism, secondary drive sprocket 4-3 and the secondary driven sprocket 4-4 formation of one-level drive sprocket 4-1 and one-level driven sprocket 4-2 formation, one-level drive sprocket 4-1 is connected with the mouth of driving engine 3, one-level driven sprocket 4-2 is coaxially connected with secondary drive sprocket 4-3, secondary driven sprocket 4-4 is connected with the rotating shaft of reel 2, between one-level drive sprocket 4-1 and one-level driven sprocket 4-2, secondary drive sprocket 4-3 and secondary driven sprocket 4-4, is connected by chain; Counting machine 5 is mechanical counters of rope skipping use, comprises the axle core rotating with the rotating shaft of reel, and increases or reduce the dial plate of numerical value with the positive and negative hand of rotation of axle core; On steel rope 6, adjacent scale value difference is three meters, and different scale value is denoted as different colors.
Counting machine adopts general rope skipping mechanical counter used, when forward, forward records numerical value, when reversion on the basis of this numerical value backwards calculation numerical value, in construction, when hoisting heavy hour counter by zero start calculate, the hour counter backwards calculation that declines after lifting final reset-to-zero scale, this counter structure is simple, work safety, and 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 when constructability, and different scale value adopts different colours to distinguish, and can greatly be convenient to visualizing operation, makes operation easier.
