Abstract
The utility model discloses a depth indicator for a winch. The depth indicator comprises a big gear, a screw, a big chain wheel, a chain, a small chain wheel, a small gear shaft, a ruler, a pointer, a nut and a small gear, wherein the big gear is fixed with a winding drum and rotates along with the winding drum; the small chain wheel and the small gear are arranged on the small gear shaft; the big gear is meshed with the small gear and drives the small gear, the small gear shaft and the small chain wheel to rotate; the big chain wheel is arranged on the screw; one end of the chain is meshed with the small chain wheel, and the other end of the chain is meshed with the big chain wheel; the big chain wheel drives the screw to rotate; the nut is arranged on the screw and does linear motion on the screw along with the rotation of the screw; the pointer is arranged on the nut, and indicates on the ruler; the scale indicated by the pointer displays the position of a heavy object pulled by the winch; the ruler of the depth indicator is positioned at the right front part of the winch; the ruler and the screw are horizontally arranged; and the ruler at the opposite vertical side is more convenient for observation of an operator. The depth indicator disclosed by the utility model has the advantages of simple structure and convenience for manufacture.
Description
Technical field
The utility model belongs to the design of winch structure, and it has particularly related to a kind of indicating device that winch draws the weight position of measuring.
Background technology
Winch is to be used for indicating winch to draw the device of weight position with depth indicator; Generally the inner gear by the reel ends of sure brake side is connected with change speed gear box; Change speed gear box drives screw mandrel, and screw mandrel drives pointer, through pointer the weight position is reacted on the scale.The machining interal difficulty is very big on the reel of sure brake side; The too complicated cost of change speed gear box is higher; Screw mandrel and scale vertically are arranged in reel one side, are not easy to the operator and observe.
Summary of the invention
The goal of the invention of the utility model is the defective that overcomes prior art, and shows that through a kind of device simple in structure winch draws the winch of weight position to use depth indicator.
In order to accomplish the goal of the invention of the utility model, the utility model adopts following technical scheme:
A kind of winch of the utility model is used depth indicator, and it comprises: big gear wheel, screw mandrel, hinge wheel, chain, minor sprocket, pinion shaft, scale, pointer, nut and miniature gears, and wherein: big gear wheel and reel are fixed; And along with the reel rotation, minor sprocket and miniature gears are contained on the pinion shaft, big gear wheel and pinion; The large gear turn the small gear, the rotation of pinion shaft and minor sprocket, and hinge wheel is contained on the screw mandrel, and an end of chain meshes with minor sprocket; The other end and hinge wheel engagement, hinge wheel drives the screw mandrel rotation, and nut is housed on screw mandrel; Along with the rotation of screw mandrel, nut is moving linearly on screw mandrel, and pointer is housed on nut; The pointer indication is on scale, and the scale of pointer indication demonstrates the position of weight that winch draws;
A kind of winch of the utility model is used depth indicator, and wherein: said reel, pinion shaft and screw mandrel are parallel;
A kind of winch of the utility model is used depth indicator, and wherein: said scale is carved with scale.
The winch of the utility model is compared with existing winch depth indicator with depth indicator, has following constructional feature:
1. the depth indicator scale is positioned at the winch dead ahead, and scale and screw mandrel are laterally to place, and observes with respect to the scale of erectting the side operator that is more convenient for;
2. simple in structure, easily manufactured, the driving device of depth indicator is made up of a pair of external toothing straight gear and pair of sprocket, and installation processing is all very convenient.
Description of drawings
Fig. 1 is the forward scheme drawing of a kind of winch of the utility model with depth indicator;
Fig. 2 is the side schematic view of Fig. 1.
In Fig. 1 and Fig. 2, label 1 is a big gear wheel; Label 2 is a reel; Label 3 is a screw mandrel; Label 4 is a hinge wheel; Label 5 is a chain; Label 6 is a minor sprocket; Label 7 is a pinion shaft; Label 8 is a scale; Label 9 is a pointer; Label 10 is a nut 10; With label 11 be miniature gears.
The specific embodiment
See figures.1.and.2; The winch of the utility model comprises with depth indicator: big gear wheel 1, screw mandrel 3, hinge wheel 4, chain 5, minor sprocket 6, pinion shaft 7, scale 8, pointer 9, nut 10 and miniature gears 11; Big gear wheel 1 is fixing with reel 2, and along with reel 2 rotations, minor sprocket 6 is contained on the pinion shaft 7 with miniature gears 11; Big gear wheel 1 and miniature gears 11 engagements; Big gear wheel 1 drives miniature gears 11, pinion shaft 7 and minor sprocket 6 rotations, and hinge wheel 4 is contained on the screw mandrel 3, and reel 2, pinion shaft 7 and screw mandrel 3 are parallel.One end of chain 5 and minor sprocket 6 engagements, the other end and hinge wheel 4 engagements, hinge wheel 4 drives screw mandrel 3 rotations; Nut 10 is housed on screw mandrel 3, and rotatablely moving of nut is limited, along with the rotation of screw mandrel 3; Nut 10 is moving linearly on screw mandrel 3, and pointer 9 is housed on nut 10, when the winch trail run; The operator can make a mark on scale 8 when weight runs to several ad-hoc location; The mark that is provided with in advance is as the scale of scale 8, and during the winch operation, pointer 9 can indicate the position of weight that winch draws on scale 8.
Principle of work
Winch motor drives reel 2 runnings through series of gears, and steel rope is wrapped on the reel 2, and the rotation of reel 2 drives big gear wheel 1 rotation; Because big gear wheel 1 and miniature gears 11 engagements; Chain 5 and hinge wheel 4 and minor sprocket 6 engagements, miniature gears 11 is coaxial with minor sprocket 6, and hinge wheel 4 is coaxial with screw mandrel 3; Nut 10 is moving linearly on screw mandrel 3; Through above-mentioned drive connection, the rotation of reel is moved on scale 8 with the pointer 9 that certain gear ratio drives on the nut 10, finally reflects the folding and unfolding length of steel rope on the reel and the corresponding relation of scale high scale.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the spirit of the utility model, the utility model can be done any type of modification.
