Problems solved by technology
Heavy-duty trucks can weigh up to 80t, so this type of wire rope is required to be extremely safe, have extremely high tensile stress and the ability to withstand impact loads, and require a high service life. The end of the steel wire rope is connected, but due to insufficient fixing force, the steel rope is prone to slippage, causing a great safety hazard

Embodiment Construction
[0024] figure 1 It is a structural diagram of the super-strength steel joint cable used for the lift of the ro-ro ship of the present invention.
[0025] A super-strength steel joint cable for a ro-ro ship lift, including a steel wire rope 4, one end of the steel wire rope 4 is connected with a steel pressed joint 3 with a screw, and two nuts are used at the screw rod to adjust the tension of the steel wire rope. It is preferably a common hex nut 1, and the other is a high-strength shouldered hex nut 2 with a 30° angle on the end face, and the high-strength shouldered hex nut 2 with a 30° angle cooperates with a support seat 6. Among them, such as figure 2 As shown, the screwed steel pressed joint 3 is preferably formed by pressing an M64 screw 31, a pressed joint sleeve 32, and a steel wire rope into one body.
[0026] The other end of the wire rope 4 is connected with a wedge joint 7, and may be equipped with a wire rope rope clip 8.
[0027] Such as figure 1 As shown, ...

The present invention provides a connection structure of a super-strength steel joint inhaul cable and a roll-on roll-off ship elevator which belongs to the technical field of rope pulling. The steel joint inhaul cable is provided with a structure as follows: one end of a wire rope is connected with a steel pressed joint with a screw; the screw is provided with two nuts used for adjusting the tension of the wire rope; and the other end of the wire rope is connected with a wedge joint. The steel joint inhaul cable is connected with an elevator in a way as follows: one end of the steel pressed joint with the screw which is provided with the nut is fixed on a deck steel clapboard of the elevator, and the wedge joint is fixed on an ear plate of a cabin bottom steel clapboard. The steel joint inhaul cable is fixed, the elevator deck is raised and dropped by the rising and the descending of an oil cylinder, the steel joint inhaul cable is fixed and positioned integrally, and the elevating work is finished by every cable passing nine pulley blocks. The steel joint inhaul cable ensures the elevating structure is more compact, more reasonable and more convenient for changing and the work efficiency is increased.
Description
technical field [0001] The invention relates to the technical field of drag cables, in particular to a connection structure between a roll-on-roll-off ship elevator and a super-strength steel joint drag cable. Background technique [0002] There are a lot of heavy vehicles on my country's offshore routes. When boarding the ship, the heavy vehicles need to be put into the bottom warehouse, and after arriving at the destination port, the heavy vehicles need to be transported to the lifting deck. This kind of rigging is used for this purpose. There are 8 riggings installed on each ship, and the wire rope and steel crimping rigging are fixed on both sides of the middle hydraulic cylinder, four on each side. The rigging passes through the bottom of the lifting deck, and the entire deck is raised, lowered, fixed and positioned through the pulley block, so that heavy vehicles can be easily lowered into the bottom compartment or raised to the deck. Heavy-duty trucks can weigh up to...
