Abstract
The utility model relates to the field of a force measuring device and specifically relates to a winch force measuring device. The winch force measuring device comprises a unidirectional torsional force arm, a connection pin, a connection crank, a support, a pivot pin type sensor, a shaft snap ring and a radial spherical plain bearing, wherein the unidirectional torsional force arm is connected with one end of the connection crank through the connection pin, the other end of the connection crank is connected with the support through the pivot pin type sensor, the radial spherical plain bearing is arranged between the connection crank and the pivot pin type sensor, and two ends of the pivot pin type sensor are fixed on the support through the shaft snap ring. The winch force measuring device has advantages of simple design, convenient mounting and operation, high test precision and low error.
Description
Technical field
The utility model relates to the device for measuring force field, is specifically related to a kind of winch device for measuring force.
Background technology
The winch device for measuring force is mainly used in need surveying the winch of reel steel wire ropes or hawser pull power, and common winch device for measuring force is all more loaded down with trivial details or cost is high.Common winch dynamometry all adopts axle bed formula sensor or does a unsplit bedplate at present, band pressure sensor on base, and these two kinds of method precision are extreme difference all.While adopting the axle bed formula, because arrange winch hawser left and right, when hawser all therein during an end, the stressed larger demonstration numerical value of axle bed formula sensor height just, precision extreme difference.And on base with the pressure sensor at first first do one with the counter-base that the winch base area is equally large, intensity is high, then on four fulcrums the setting pressure sensor, so kind method cost is high, and precision is difficult to guarantee.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of winch device for measuring force, easy for installation, test is simple, and the pulling force error is low, and the precision of measurement is high.
In order to reach the foregoing invention purpose, the utility model proposes following scheme:
The winch device for measuring force, it comprises unidirectional toggle, connects bearing pin, connecting crank, support, axial pin type sensor, circlip for shaft and plain radial bearing, unidirectional toggle is connected to connecting crank one end by connecting bearing pin, the other end of connecting crank links together by axial pin type sensor and support, between connecting crank and axial pin type sensor, plain radial bearing is housed, the axial pin type sensor two ends are fixed on support by circlip for shaft.
Described unidirectional toggle is contained in spool shaft one end, and unidirectional toggle also connects dynamic brake is housed outward, and dynamic brake is installed on unidirectional toggle outside, i.e. spool shaft one end.
Described support is connected on winch frame.
The utility model has the advantages that simplicity of design, fitting operation is convenient, and measuring accuracy is high, and error is low.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is partial sectional view of the present utility model.
Embodiment
For the utility model is further illustrated, below in conjunction with the Figure of description introduction:
With reference to accompanying drawing 1 and Fig. 2, the winch device for measuring force, it comprises unidirectional toggle 1, connects bearing pin 2, connecting crank 3, support 4, axial pin type sensor 5, circlip for shaft 6 and plain radial bearing 7, unidirectional toggle 1 is connected to connecting crank 3 one ends by connecting bearing pin 2, the other end of connecting crank 3 links together by axial pin type sensor 5 and support 4, between connecting crank 3 and axial pin type sensor 5, plain radial bearing 7 is housed, axial pin type sensor 5 two ends are fixed on support by circlip for shaft 6.
The winch device for measuring force, mainly to utilize on spool shaft (or rotating drive shaft) dynamic brake (the same power clutch of principle) is arranged, the still that dynamic brake is mainly used by rotatable moving plate and external stability forms, because the moving plate of dynamic brake is that the transmission gear inner by it is enclosed within on axle, while working, effect due to friction disc, the friction disc of moving plate and still can be fitted, now still has a rotation trend, and still is fixed on device for measuring force on a unidirectional toggle, unidirectional toggle has a trend rotation equally, now due to the effect of lever, unidirectional toggle can have to the pin type sensor power of a shearing, this power is just pulling force (need be calculated by the pin type sensor microcomputer) actual on reel.
