Pressure measurement and rope guide device of marine heavy-load winch

Abstract

The invention discloses a pressure measurement and rope guide device of a marine heavy-load winch. A three-pulley pressure measurement mechanism on a pressure measurement device can synchronously swing along with the swing of a mooring rope by designing a reasonable pressure measurement device mechanism. Meanwhile, a rope guide device enables the mooring rope passing the three-pulley pressure measurement mechanism on the pressure measurement device to keep synchronous and collaborative movement in the axial direction of a rolling barrel when a mooring rope wound on the rolling barrel is wound up and released, and enables the pulley pressure measurement mechanisms to move up and down along a vertical shaft along with wind-up and release movements of the mooring rope on the rolling barrel to keep a rope outlet angle unchanged. Therefore, the defects that the mooring rope passing the three-pulley pressure measurement mechanism generates additional force and moment and measurement accuracy is affected due to the facts that the mooring rope irregularly swings and the rope outlet angle constantly changes are overcome, the entire device can carry out rope guiding reasonably and orderly, and the equipment failure rate is reduced. The pressure measurement and rope guide device of the marine heavy-load winch can achieve smooth rope guiding conveniently and accurately, and overcomes the defect that a traditional three-pulley pressure measurement mechanism can not measure an accurate value due to the influence of environmental conditions.

Description

Technical field: [0001] The invention relates to a force-measuring device and a rope-laying device of a deep-sea heavy-duty winch used for ship equipment, specifically refers to a device that can minimize the irregular swing of the cable during work and reduce the accuracy of the force-measuring device. It is a device that produces an impact and at the same time can realize the compact stacking of cables back and forth along the axis of the drum so as to realize the regular discharge of cables. technical background: [0002] The deep-sea winch is a device used for lowering important instruments and equipment in offshore engineering. Generally, the winch is required to be equipped with a tension display function. In order to realize the display of tension, a tension sensor must be installed at the output end of the winch cable, and the installation position of the sensor is a key factor affecting the measurement result. The angle of the rope is constantly changing. If the me...

Problems solved by technology

[0003] The force measuring device of the cable on the winch consists of three small pulleys and a pressure sensor. The middle small pulley is not on the same line as the other two small pulleys. The cable needs to pass through the three small pulleys in turn. When the cable is tensioned, it is installed in the middle The pressure sensor on the small pulley is under force, and the force is converted into the tension of the cable by measuring the force. When the winch working in the deep sea lifts heavy objects, the cable will be affected by the impact of seawater flow, and the cable will swing irregularly. If the pulley measures When the force device is fixed on the winch, the small pulley in the middle will be subjected to the additional force generated by the impact of seawater on the cable, thus affecting the accuracy of the force measurement. The accuracy of the force, so here is a need for a force measuring device that can swing irregularly with the cable and can keep the angle of the rope unchanged, so the present invention aims to solve the above problems

[0004] At the same time, when working in deep sea, the winch needs longer cables, but the longer cables will be wound in multiple layers on the drum, and the cables will overlap when they are wound in multiple layers on the drum. The uniformity will not only reduce the length of the cable winding, but also sometimes cause the rope to be stuck, so a device is needed to make the cable winding on the drum regularly layer by layer, so that the cable winding is compact and orderly, so that It can ensure the smooth operation of the winch and prevent the phenomenon of jamming
