Embodiment 1

[0022] Such as figure 1 , figure 2 , image 3 , Figure 4 The shown one kind of flexible installation dynamometer and speed measuring device includes a pulley block suspended on the fixed bracket 1 by cables 3 for force measurement and speed measurement, the fixed bracket 1 is installed on the working plane by bolts, and the cables 3 are worn on the fixed bracket On the two lifting lugs 2 of 1, adjust the length according to the swing range when it is working; the pulley block includes a force measuring pulley 7 and two speed measuring pulleys installed on the support frame through the force measuring pin 8 and the speed measuring pin 9 respectively 4. The support frame includes two opposing support plates 5 connected by four bolts, two speed measuring pulleys 4 are respectively installed between the two support plates 5, and each support plate 5 is provided with two downward protruding Connecting part, between the two connecting parts, there is an installation ear plate 6...

Embodiment 2

[0026] The difference between this embodiment and Embodiment 1 lies in that the wrapping angle α formed by the cable channel of the winch and the force-measuring pulley 7 is 175 degrees.

[0027] All the other features are the same as in Example 1.

Abstract

The invention discloses a flexible-installation force and speed measuring device and relates to the technical field of cable tension and speed detecting devices of winches. The flexible-installation force and speed measuring device comprises a pulley block suspended on a fixing support through cables; the pulley block comprises a force measuring pulley and two speed measuring pulleys, which are mounted on a support rack through a force measuring hinge pin and speed measuring hinge pins respectively, wherein the force measuring pulley is arranged under the two speed measuring pulleys; winch cable passages at a wrap angle of alpha from the force measuring pulley are formed between the two speed measuring pulleys and the force measuring pulley; one of the speed measuring hinge pins is provided with a speed measuring rotary encoder, a stress sensor is arranged inside the force measuring hinge pin, and the speed measuring rotary encoder and the stress sensor are electrically connected with a microcomputer processor. Compared with the prior art, the force measuring pulley and the two speed measuring pulleys can achieve automatic adjustment to adapt to continuous change in output angles and the number of layers of the cable, and monitored tension and cable speed data can be more direct and more accurate.

Description

technical field [0001] The invention relates to the technical field of a cable tension and speed detection device for a hoisting winch, in particular to a detection device for monitoring the tension and speed of a hoisting winch used in ships and marine engineering. Background technique [0002] The hoisting winches used in ships and ocean engineering, such as mooring winches, towing winches, and ship moving positioning winches, require real-time cable tension and speed to be monitored and displayed on the console when the equipment is running. The corresponding force measuring and speed measuring devices are used to complete the work of data collection, signal conversion, and transmission. Generally, the force measuring and speed measuring devices are set separately. The force measuring device adopts the method of installing the loaded shaft in the transmission chain on the loaded bearing seat. The structure; the speed measuring device adopts the structure of the switch cou...
