Abstract
The utility model discloses a height indicator, wherein two half worm wheels (401) and a half worm wheel (402) are staggered artificially and are fixedly connected through a preload tension spring (10) to form an integrated worm wheel (4) by encircling, four microswitches (1) are arranged on a rotating shaft of the integrated worm wheel, a drive input end of a worm (9) is connected with a rotating shaft of a hoisting machine, and is connected with a connecting device (13) of an encoder by using a connecting mode of a sprocket wheel, a gear, a connecting sleeve and a half body according to requirements. The height indicator achieves the technical effect of zero clearance engagement of the worm wheel (4) and the worm (9), and improves sensitivity, thereby accurately displaying lifting height of the hoisting machine, and solving the technical problems that traditional height indicators cause the hoisting machine not to be connected with high-end equipment because of low reaction sensitivity and can not achieve automation and remote control. The height indicator is simple in structure, low production cost, simple and convenient to operate and control and easy to implement and promote, and has high market value and competitive value.
Description
Technical field
The utility model relates to height indicator, especially a kind of height indicator being applied on winch.
background technology
Along with scientific and technological progress, winch towards the future development of Long-distance Control and automation, meets social demand with this gradually, and will realize automation and the Long-distance Control of winch, the height indicator main tool that is absolutely necessary.
Height indicator is by the engaged transmission of worm and wheel, to drive the rotation of pointer on indicating device dial plate, indication gate height.The back lash of traditional height indicator worm and wheel is excessive, and worm screw need to be behind the eliminating gap that turns an angle, and worm gear just starts to rotate, and reaction sensitivity is very low.If the heave amplitude of winch is too small, the pointer on indicating device dial plate is at all motionless.When winch is become landing or become while rising from landing from rise, need the back lash of eliminating larger, had a strong impact on the accuracy rate of height indicator, thereby caused the adjustable height of winch inaccurate, cannot access more high-end instrument and realize automation and Long-distance Control.
utility model content
The technical problems to be solved in the utility model is to provide a kind of height indicator, this height indicator is applicable to winch, can very accurately demonstrate the adjustable height of winch, evade traditional height indicator and because reaction sensitivity is low, caused winch cannot access the problem that high-end instrument is realized automation and Long-distance Control.And this height indicator can make four limit points need to the lifting of the winch be connected with this height indicator according to difference, protected the safe operation of winch.
For solving the problems of the technologies described above, technical solution adopted in the utility model is specially and comprises worm gear and worm screw, specifically, by misplacing artificially between two and half worm gear A and half worm gear B and being connected and fixed by pretension extension spring, forms the whole worm gear of filling the span of a man's arms and forming.
Four micro-switchs are installed on the turning cylinder of described worm gear, its objective is while needing to rise or to decline to gate according to difference and make four limit points, thereby ensure the safe operation of gate.
In one end of worm screw (9), a device being connected with coder (13) is set, to increase the length of the active input end of worm screw, is conveniently connected with the turning cylinder of winch.
The active input end of described worm screw (9) is connected with the turning cylinder of winch, and connection mode is sprocket wheel, gear or adapter sleeve, then uses different dial plates according to different connection modes.
In order to adapt to the coder of different specifications and models, one end of described worm screw and the connecting device of coder, the spindle nose of worm screw and connecting panel can change as required.
accompanying drawing explanation
Fig. 1 is the worm and wheel engaging structure schematic diagram of height indicator
Fig. 2 be in Fig. 1 A face to view
Fig. 3 is the dial plate of height indicator
In figure: 1 micro-switch, 2 nylon cams, 3 nylon spacing collars, 401 half worm gears, 402 half worm gears, 4 whole worm gears (note: the integral body after half worm gear 401 and half worm gear 402 are filled the span of a man's arms) 5 semi-scroll wheel seats, 6 bearings, 7 dial plate seats, 8 transparent windows, 9 worm screws, 10 pretension extension springs, 11 pointers, 12 dial plates, 13 worm screws and encoder connecting device.
The specific embodiment
As Figure 1-3: on semi-scroll wheel seat 5, whole worm gear 4 is filled the span of a man's arms and is formed by two and half shape structure half worm gears 401 and half worm gear 402, between half worm gear 401 and half worm gear 402, by pretension extension spring 11, be connected and fixed, during installation, two and half worm gears 401 and 402 are misplaced, and then with pretension extension spring 10 pretensions, like this, whole worm gear 4 after filling the span of a man's arms and worm screw 9 be energy tight mesh just, increased the sensitivity of height indicator, during work, under the rotation of worm screw 9, whole worm gear 4 rotates and drives pointer 11 rotations on the dial plate 12 that is arranged on dial plate seat 7 places immediately.In addition nylon cam 2 and the nylon spacing collar 3 adjacent with worm screw 9.On said structure basis, four micro-switchs 1 are installed on the turning cylinder of whole worm gear 4, can make four limit points need to the lifting of the winch being connected with height indicator according to difference, protected the safe operation of winch; A worm screw and encoder connecting device 13 are set in one end of worm screw 9, to increase the length of the active input end of worm screw 9, can use the connection modes such as sprocket wheel, gear, adapter sleeve, halfbody to be connected with the turning cylinder of winch.In Fig. 2 is bearing, and bearing can need version according to difference.
The other Chinese utility model patent of the height indicator of said structure and applicant " plugging device on rolling open and close machine base " supports the use, can significantly improve mechanicalness and can be handling, staff also can be by the further accuracy of checking dial plate 8 of transparent windows 8.More convenient for height indicator is connected with winch, be not subject to space and position limitation, different connection mode for different positions, should adopt suitable bearing 6 to be achieved.The utility model is filled the span of a man's arms whole worm gear 4, misplace by two and half shape structure half worm gear 401 and half worm gear 402 by adopting, and be connected and fixed by pretension extension spring 11, use again the technical scheme of pretension extension spring 10 pretensions, produced the technique effect of whole worm gear after filling the span of a man's arms 4 and worm screw 9 tight meshs, increased the sensitivity of height indicator, and can very accurately demonstrate the adjustable height of winch, evade traditional height indicator and because reaction sensitivity is low, caused winch cannot access the problem that high-end instrument is realized automation and Long-distance Control.And this height indicator can make four limit points need to the lifting of the winch be connected with this height indicator according to difference, protected the safe operation of winch.The utility model is simple in structure, and productive costs is low, controls simply, is easy to promotion and implementation, has higher marketable value and Competitive Value.
