Problems solved by technology

This method can only be adjusted once before safety, and cannot be adjusted later because it is closed in the box, and if the adjustment is not appropriate, it is easy to cause the bearing block to get stuck and affect the tension measurement accuracy

Embodiment

[0018] figure 1 It is a schematic diagram of the structure of the device in the unstressed state of the cable, which includes tension wheel 1, large bearing 2, force application sleeve 3, force sensor 4, sensor seat 5, flat key 7, flange sleeve 6 from outside to inside; tension wheel 1 Inner hole and large bearing 2 Outer ring set, large bearing 2 Inner ring and force sleeve 3 Outer circle set, force sleeve 3 and flange sleeve 6 Set, flange sleeve 6 is fixed to the winch box, flange sleeve 6 Cooperate installation through bearing 8 and supporting shaft 9 in the hole.

[0019] When the cable 10 is not stressed, under the action of the gravity G of the tension wheel 1, the large bearing 2, and the force application sleeve 3, the gap δ1 between the inner hole of the force application sleeve 3 and the outer circle of the flange sleeve 6 is located below. At this time There is also a gap δ4 between the contact 4a of the sensor 4 and the inner hole of the force application sleeve, ...

Abstract

The invention provides an internal cable tension measuring device for a tension attenuation winch, which includes a tension pulley, a big bearing, a force-exerting sleeve, a force sensor, a sensor seat, a flange sleeve and a flat key. The internal cable tension measuring device is characterized in that as force is transversely exerted to the force sensor, the cable tension exerted on the tension pulley is exerted to the force sensor arranged in the flange sleeve along the resultant force direction under the action of the force-exerting sleeve, and suitable gaps are arranged between the flat key and the force-exerting sleeve as well as between the force-exerting sleeve and the flange sleeve, the sensor is free from the influence of the weight of the device, the precision of the stability of the tension measurement is ensured, and the device can be suitable to the variation of the cable wrap angle within a certain range.

Description

technical field [0001] The invention relates to a measuring device, in particular to a tension attenuation winch built-in cable tension measuring device based on a cable integrating load bearing, power transmission and communication. Background technique [0002] The cable tension measurement can provide the change of the tensile force when the cable is loaded. The traditional three-roller cable tension measurement method is often used to measure the tension of steel wire ropes. When the cable is a cable, this measurement method is not suitable for cable tension measurement because it does not meet the requirements of the minimum bending radius of the cable and will affect the service life of the cable. [0003] Invention patent "tension measurement device" (ZL200980114914.8) constructs the tension measurement device to DC magnetize a part of the long magnetic element of the measurement target object to a range close to the saturation magnetization, by detecting the spatial ...
