Description

Technical Field

[0001] The utility model relates to a bottom support frame of a rescue boat, in particular to a lifting type bottom support frame of a rescue boat. Background Art

[0002] At present, the bottom support frame of the rescue boat includes a support block and a rotating swing arm, the support block is fixed at one end of the rotating swing arm, and the bottom support frame of the rescue boat is arranged on the cradle for hoisting the lifeboat on the mother ship through the other end of the rotating swing arm. When the lifeboat is hoisted onto the cradle, it is necessary to manually rotate the rotating swing arm of the bottom support frame of the rescue boat so that the support block is supported on the bottom of the rescue boat, thereby fixing the lifeboat. When it is necessary to hoist and place the lifeboat, it is necessary to manually rotate the rotating swing arm of the bottom support frame of the rescue boat so that the support block is moved away from the bottom of the rescue boat. Since the bottom support frame of the rescue boat is relatively bulky, it is time-consuming and laborious to hoist and place the lifeboat, and it is also easy to affect the safety of the staff. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the utility model is to provide a lifting type rescue boat bottom support frame, which does not require manual operation and thus will not affect the safety of the staff.

[0004] The technical content of the utility model is a bottom support frame of a lifting type rescue boat, which is characterized in that it includes a support block, a slide tube, a fixed tube and an oil cylinder; the oil cylinder is arranged in the fixed tube; the slide tube is arranged in the fixed tube, one end of the slide tube is fixedly connected to the oil cylinder, and the other end of the slide tube extends out of the fixed tube and is fixedly connected to the support block.

[0005] In order to better support the support block on the bottom of the rescue boat, the utility model also includes a side support rod. The support block is V-shaped, the sliding cylinder and the fixed cylinder are rectangular cylinders, and a side support rod is respectively provided between the two sides of the support block and the sliding cylinder; and sliding grooves corresponding to the side support rods are provided on both sides of the fixed cylinder.

[0006] In order to enable the slide cylinder to slide well in the fixed cylinder, the utility model further comprises slide bars, and a plurality of slide bars are arranged on the outer wall of the slide cylinder and the inner wall of the fixed cylinder in pairs.

[0007] Compared with the prior art, the utility model has the following advantages: the utility model pushes out and retracts the support block through the oil cylinder, thereby eliminating the need for manual operation and thus not affecting the safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the utility model.

[0009] Figure 2 It is an exploded view of the utility model. DETAILED DESCRIPTION

[0010] like Figure 1 and Figure 2 As shown, a bottom support frame of a lifting rescue boat is characterized in that it includes a support block 1, a slide cylinder 2, a fixed cylinder 3, an oil cylinder 4, a side support rod 5 and a sliding strip 6; the support block 1 is V-shaped, the slide cylinder 2 and the fixed cylinder 3 are rectangular cylinders, and the oil cylinder 4 is arranged in the fixed cylinder 3; the slide cylinder 2 is arranged in the fixed cylinder 3, one end of the slide cylinder 2 is fixedly connected to the oil cylinder 4, and the other end of the slide cylinder 2 extends out of the fixed cylinder 3 and is fixedly connected to the support block 1; a side support rod 5 is respectively arranged between the two sides of the support block 1 and the slide cylinder 2; slide grooves 3.1 corresponding to the side support rod 5 are arranged on both sides of the fixed cylinder 3, and a plurality of sliding strips 6 are arranged on the outer wall of the slide cylinder 2 and the inner wall of the fixed cylinder 3 in pairs.

[0011] The working principle of the utility model is that the utility model is fixed on the cradle of the lifeboat through the fixing cylinder 3. When the lifeboat is hoisted onto the cradle, the sliding cylinder 2 is driven by the oil cylinder 4 to slide to the outside of the fixing cylinder 3, so that the support block 1 is supported on the bottom of the rescue boat; when the lifeboat needs to be hoisted, the sliding cylinder 2 is driven by the oil cylinder 4 to slide into the fixing cylinder 3, so that the support block 1 is moved away from the bottom of the rescue boat.
