Abstract
The utility model relates to a pulley with a detection function. The pulley with the detection function is used in a trawler and for measuring tension and routes of warps of fishing equipment. The pulley with the detection function comprises a shell, wherein the upper end of the shell is connected with a universal joint, and a head pulley wheel and an auxiliary wheel are arranged in the shell. The pulley with the detection function is characterized in that a load cell is arranged on a hinge pin of the head pulley wheel, and a route encoder is arranged on the auxiliary wheel. The pulley with the detection function has the advantages that towing tension and the towing route of the warp pulley can be measured conveniently through the load cell and the route encoder, and therefore functions of the warp pulley are increased, and convenience is brought to subject examination, tests and the like; an arresting device can be used for controlling the pulley to stop running in an emergency; and a supporting pin is arranged in the shell so that the strength of the shell is improved, and the load capacity of the warp pulley is increased.
Description
Technical field
The utility model relates to and a kind ofly has the coaster of measuring ability for trawlboat, is used for measuring pulling force and the stroke that fishing gear drags guiding principle.
Background technology
Coaster is the direction that changes pulling force as its radical function of corollary apparatus of trawlboat towing and erecting equipment.Existing coaster function ratio is more single, and for the steel rope of pile warp coaster or the pulling force of iron chains, corresponding data can't be measured and provide to the stroke of walking, and the weight of the object that drags, and puts to no little inconvenience for scientific investigation, test etc.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency that above-mentioned prior art exists, and a kind of coaster with measuring ability that can measure towing pulling force and stroke is provided.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include housing, upper end and the Hooke's coupling of housing link, be installed on head pulley and auxiliary wheel in the housing, it is characterized in that on the described head pulley bearing pin force transducer being set, be provided with the run-length encoding device on the described auxiliary wheel.
Press such scheme, described auxiliary wheel is two, is installed in respectively the front and back side of head pulley.
Press such scheme, described auxiliary wheel diameter is less than head pulley, and wheel axis is lower than the wheel axis of head pulley.
Press such scheme, described head pulley and auxiliary wheel are sprocket wheel, with the tow phase configuration.
Press such scheme, described head pulley and auxiliary wheel are rope sheave, with towing steel rope phase configuration.
Press such scheme, described housing upper end is hinged with Hooke's coupling.
Press such scheme, described housing is formed by connecting by bolt up and down by front and back clamping plate and top board, is installed on up and down the supporting pin in housing.
Press such scheme, be provided with brake equipment with the head pulley phase configuration at housing.
The beneficial effects of the utility model are: 1, can easily measure towing pulling force and the stroke that drags the guiding principle coaster by force transducer and run-length encoding device are set, increase like this function of draging the guiding principle coaster, bring convenience for scientific investigation, test etc.; 2, can in case of emergency to control coaster out of service for stop motion mechanism; 3, arrange the supporting pin in housing in, improved the intensity of housing, drag guiding principle coaster load-carrying capacity thereby increase.

Fig. 3 is the B-B cutaway view among Fig. 1.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Include housing 5, described housing is formed by connecting by bolt up and down by front and back clamping plate and top board, in housing up and down four jiaos be installed on supporting pin 3, clamping plate before and after stretch out at supporting pin two ends are by nut locking; The upper end of housing is hinged by top board and Hooke's coupling 4, be installed on head pulley 6 in the middle of in the housing, the front and back side of head pulley is installed respectively auxiliary wheel 2,8, the auxiliary wheel diameter is less than head pulley, and wheel axis is lower than the wheel axis of head pulley, on the described head pulley bearing pin force transducer is set, be provided with the run-length encoding device on described two auxiliary wheels, described head pulley and auxiliary wheel are sprocket wheel, namely at wheel key way is set circumferentially, with tow 1 phase configuration, tow is cross-linked by the oval ring and forms.In addition, be provided with brake equipment 7 with the head pulley phase configuration at housing.
The utility model can obviously improve the function of coaster, can be very large and heavily loaded at steel rope or iron chains tension variations (load: 17t) in the situation, accurately measure lineoutofservice signal pull and the stroke of walking thereof (weight ± 0.01t, stroke ± 0.05m).
