Description
Technical Field
The utility model relates to a lifting hook, in particular to a lifting hook for lifting a rescue boat by a crane on an ocean-going vessel.
Background
At present, when a rescue boat is to be hung on a big boat from the sea surface, firstly, a person on the rescue boat transfers a connecting steel rope on the rescue boat to the big boat, then the person on the big boat connects the connecting steel rope to a rescue boat lifting hook of a crane, the crane gradually puts down the rescue boat lifting hook, the rescue boat lifting hook is inserted and fixed into a lifting hook seat of the rescue boat under the traction of the connecting steel rope, then the crane hangs the rescue boat on the big boat, and then the person separates the connecting steel rope from the rescue boat lifting hook; the existing rescue boat is hung and connected with a groove and a bolt hole which is vertical to the groove at the front end part of the existing rescue boat, when a steel rope and a rescue boat lifting hook are connected, a connecting buckle at the front end of the connecting steel rope is placed into the groove at the front end part of the rescue boat, and then the bolt is inserted into the bolt hole through the bolt, so that the connecting steel rope is connected with the rescue boat lifting hook, the safety of the bolt fixed connection in the connecting mode is not high, and meanwhile, when the bolt is extracted from a lifting hook seat of the rescue boat after the rescue boat is lifted to a big boat, the transverse operation space in the lifting hook seat is limited, so that the bolt is difficult to pull out.
Disclosure of Invention
In view of the above disadvantages, the present invention provides a rescue boat hook capable of improving the safety of the connection between the rescue boat connecting steel rope and the rescue boat hook and facilitating the separation of the rescue boat connecting steel rope and the rescue boat hook.
The utility model relates to a rescue boat lifting hook, which comprises a boat lifting hook, and is characterized by also comprising a traction hook, a positioning rod, a spring, a baffle, a barrier strip, a fixed sleeve plate and a clamp spring; the front end of the boat sling hook is sequentially provided with a positioning hole, a baffle plate hole and a sling hook hole from inside to outside, two sides of the baffle plate hole are respectively provided with a sliding chute, and a clamp spring groove is arranged in the sling hook hole; the spring is arranged in a baffle hole, the baffle is arranged in the baffle hole at the front side of the spring, two sides of the baffle are respectively and fixedly connected with the rear end of a baffle strip, the two baffle strips are respectively and correspondingly positioned in sliding grooves at two sides of the baffle hole, the traction hook is arranged in a lifting hook hole, the fixed sleeve plate is sleeved on the traction hook, two sleeve plate through holes are arranged on the fixed sleeve plate, and the front end of the baffle passes through the sleeve plate through holes; the rear end of the towing hook is connected with one end of a positioning rod, the other end of the positioning rod penetrates through a separation blade and a spring respectively and then is inserted into a positioning hole, and a clamp spring is arranged at the front end of a fixed sleeve plate and is positioned in a clamp spring groove to fix the towing hook in a boat davit.
Compared with the prior art, the utility model has the advantages that: according to the rescue boat connecting steel rope, the traction hook is arranged on the front side of the boat lifting hook, the rescue boat connecting steel rope can be conveniently sleeved into or taken out of the traction hook through the sliding of the barrier strip, and meanwhile, the safety of the connection between the rescue boat connecting steel rope and the rescue boat lifting hook is greatly improved.

Detailed Description
As shown in fig. 1, 2 and 3, a rescue boat hook comprises a boat hook 1, and is characterized by further comprising a traction hook 2, a positioning rod 3, a spring 4, a baffle 5, a barrier strip 6, a fixed sleeve plate 7 and a clamp spring 8; the front end of the boat davit 1 is sequentially provided with a positioning hole 1.1, a baffle plate hole 1.2 and a lifting hook hole 1.3 from inside to outside, two sides of the baffle plate hole 1.2 are respectively provided with a sliding chute 1.2.1, and a clamp spring groove 1.3.1 is arranged in the lifting hook hole 1.3; the spring 4 is arranged in a blocking piece hole 1.2, the blocking piece 5 is arranged on the front side of the spring 4 and is positioned in the blocking piece hole 1.2, two sides of the blocking piece 5 are fixedly connected with the rear end of a blocking strip 6 respectively, the two blocking strips 6 are correspondingly positioned in sliding chutes 1.2.1 on two sides of the blocking piece hole 1.2 respectively, the traction hook 2 is arranged in a hook hanging hole 1.3, a fixed sleeve plate 7 is sleeved on the traction hook 2, two sleeve plate through holes 7.1 are arranged on the fixed sleeve plate 7, and the front end of the blocking strip 6 penetrates through the sleeve plate through hole 7.1; the rear end of the towing hook 2 is connected with one end of the positioning rod 3, the other end of the positioning rod 3 penetrates through the separation blade 5 and the spring 4 respectively and then is inserted into the positioning hole 1.1, and the clamp spring 8 is arranged at the front end of the fixing sleeve plate 7 and is positioned in the clamp spring groove 1.3.1 to fix the towing hook 2 in the boat hook 1.
The working principle of the utility model is that in the initial state, a barrier strip 6 is blocked at the front side of the towing hook 2 under the action of the spring 4; when the rescue boat connecting steel rope is sleeved in the traction hook, the barrier strip 6 is forced to move towards the boat hook 1, then the rescue boat connecting steel rope is sleeved in the traction hook, then the barrier strip 6 is loosened, and under the action of the spring 4, the barrier strip 6 is blocked at the front side of the traction hook 2 again, so that the rescue boat connecting steel rope cannot fall off from the traction hook; when taking out the rescue boat connection steel rope from the towing hook, only need make the blend stop 6 remove to boat davit 1 with exerting oneself earlier, can take out the rescue boat connection steel rope from the towing hook easily.
