Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 1, a lifting hook auxiliary device, including haulage rope 1, lifting rope 2, rings 3, buckle 5, set up at the through-hole 4 at the hook point position of electric block's lifting hook 6, rings fixed mounting is on mechanical equipment under water, through-hole, rings are passed in proper order to haulage rope one end, and the both ends of haulage rope are located rings both sides top and fixed mounting subaerial respectively, buckle fixed mounting is in lifting hook lower part rear end, and the buckle is located the focus of lifting hook below, and lifting rope is located the lifting hook rear side, and lifting rope one end is connected fixedly with the buckle, and this device mainly adopts wire rope as the traction structure, and the cost of manufacture is low, the direction of the control lifting hook of being convenient for, and this device can carry out reasonable chooseing for use to haulage rope, lifting rope's specification and length according to.

In this embodiment, the hauling rope and the lifting rope are both steel wire ropes.

In this embodiment, the buckle includes two splint that the symmetry set up, and the double-layered groove of holding lifting hook is seted up at the middle part of two splint binding surfaces, and the double-layered groove of holding lifting rope is seted up to the rear end of two splint binding surfaces, and two splint both ends are through bolt locking with lifting rope, lifting hook clamping.

The operation steps are as follows: (1) firstly, stringing a steel wire rope with proper length on a flying ring of underwater mechanical equipment as a hauling rope, and fixing one end of the hauling rope on a personnel operating point or a personnel operating platform on the ground; (2) the other end of the traction rope passes through the through hole on the lifting hook; (3) a buckle is fixedly arranged at the rear end of the lifting hook, and the lower end of the lifting rope is fixedly connected with the buckle so as to be convenient for the control of the lifting hook; (4) when the mechanical equipment needs to be lifted, the electric hoist lowers the lifting hook, and the lifting hook is lowered to the position of the mechanical equipment lifting ring along the traction rope under the respect of the traction rope; (5) lifting a lifting rope, applying upward force to a lifting ring at the tail part of the lifting hook by the lifting rope to enable the hook tip of the lifting hook to be downward, controlling the lifting hook to move towards the direction close to the lifting ring through the lifting rope to enable the lifting hook to hook the lifting ring of the mechanical equipment to be lifted, and then operating an electric hoist to lift the mechanical equipment to a maintenance position for maintenance and repair; (6) after the maintenance is accomplished, operation electric block transfers mechanical equipment to target in place under water, then, lift the lifting rope, give the ascending effort of a rings of lifting hook afterbody by the lifting rope, make the hook point of lifting hook just downwards, then move to the rings direction that breaks away from mechanical equipment through lifting rope control lifting hook, make lifting hook and rings separation, control electric block afterwards upwards withdraws the lifting hook along the haulage rope, after work is fixed haulage rope, lifting rope, accomplish work.

If this patent discloses or refers to parts or structures that are fixedly connected to each other, the fixedly connected may be understood as: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In the description of this patent, it is to be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the patent, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the patent.
