Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship launching equipment, in particular to a multi-purpose lifting lug for a slipway launching slide. Background Art
[0002] Gravity oiled slideway launching is a common method of launching ships. It requires setting up multiple launching slides in series, applying oil on the lower surface of the launching slides, placing the launching slides on the slideway, and the ship uses its own gravity to slide into the water from the slideway with the launching slides.
[0003] The launching skid mainly consists of a main body, wooden pads fixed above and below the main body, and lifting ears distributed on the sides of the main body. When launching, the launching skids need to be rigidly connected with shackles to prevent displacement between the skids. The wooden pads above the launching skid need to be connected to the skid through the lifting ears to ensure the recovery of the wooden pads. The launching skid needs to be salvaged, lifted and repaired through the lifting ears.
[0004] Usually, a plurality of hanging ears with different purposes are dispersedly arranged on both sides of the main body to achieve the above functions. Utility Model Content
[0005] The utility model aims to provide a multi-purpose lifting lug for a slipway launching water slide which integrates multiple functions in one, in view of the deficiencies in the prior art.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a multi-purpose lifting ear for a slipway launching skid, comprising a bottom plate, the bottom plate is vertically fixed with a lashing main board, the front section of the lashing main board is provided with a first main board lifting hole, the front section of the lashing main board is provided with a second main board lifting hole, a first reinforcing web is arranged vertically and fixedly connected to the middle of the bottom plate and the lashing main board respectively, the first reinforcing web has a first web lifting hole, a second reinforcing web is arranged vertically and fixedly connected to the middle of the bottom plate and the lashing main board respectively, the second reinforcing web has a second web lifting hole, and side plates are arranged vertically and fixedly connected to the bottom plate and the rear end of the lashing main board respectively. It should be further explained that the first web lifting hole and the second web lifting hole are used for the lifting of a single launching skid, the first main board lifting hole is used for the connection between launching skids, and the second main board lifting hole is used for the connection of the pads above the launching skid.
[0007] Preferably, the bottom plate is provided with a plurality of plug welding holes.
[0008] Preferably, the front upper end of the lashing main plate, the front upper end of the first reinforcing web, the front upper end of the second reinforcing web, and the four corners of the bottom plate are all rounded. The rounded corner treatment is used to prevent the lifting lug from damaging the ship when the skateboard rolls over.
[0009] Preferably, the first mainboard lifting hole is provided with a reinforcing ring. Since the weight carried by the launching slide changes with the launching of the ship, when the center of gravity of the ship is located at the launching slide below, the launching slide below will cause a huge pulling force on the launching slide above, so when connecting the launching slides, the reinforcing ring is provided to strengthen the connection between the launching slides to reduce damage to the lifting lugs.
[0010] Preferably, the first mainboard hanging hole is a waist-round hole, which is connected to the upper pad of the launching slide board through a chain to prevent the upper pad from being scattered and lost after launching.
[0011] Preferably, the first reinforcing web and the second reinforcing web are symmetrically arranged with respect to the binding main board.
[0012] Preferably, both corners of the upper end of the bottom plate are beveled.
[0013] Compared with the prior art, the utility model has the following advantages:
[0014] 1. The lifting lugs used to connect the launching slides, the lifting lugs connected to the upper pads of the launching slides, and the lifting lugs used to hoist the launching slides are concentrated on one lifting lug to achieve functional concentration.
[0015] 2. Since the hoisting operation time of the launching slide is staggered with the launching operation time of the launching slide, the tying grab plate and the two reinforcing webs can be used as reinforcing structures for each other during different operation times, further increasing the reliability, safety and stability of the lifting lugs.
