Description

Technical Field

[0001] The present invention relates to the technical field of ship lifeboats, and in particular to a lifeboat rapid installation and fixing platform and a use method thereof. Background Art

[0002] During the installation of the lifeboat dock, the lifeboat needs to be hoisted to the water surface. While personnel are needed to operate the lifeboat inside, a small boat is also needed outside to assist. The boat is hung using the built-in crane arm on the boat frame. According to the inclination angle of the lifeboat installed on the boat frame, the lifting point position of the lifeboat is calculated, and the lifeboat is hoisted using two combined steel wires so that the inclination angle of the lifeboat during hoisting is consistent with the inclination angle of the boat frame. The lifeboat is placed on the boat frame and fixed by operating the built-in crane arm of the boat frame. The boat hanging operation is complex, requires high coordination, and requires a large number of people.

[0003] Therefore, it is necessary to provide a lifeboat rapid installation fixing platform and a use method thereof to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a lifeboat rapid installation and fixing platform and a method of using the same, so that the lifeboat can be quickly fixed to the davit during the dock installation stage.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A lifeboat fast installation and fixing platform includes a bracket body, a telescopic bracket is provided at the head end of the bracket body, the telescopic bracket is sleeved on the outside of the bracket body, guide rails are provided on both sides of the bracket body and the telescopic bracket, rollers are provided inside the guide rails, a column is provided in the middle of the bracket body, the top of the column is pivotally connected to both sides of the bracket body, the height of the column is greater than the height of the tail of the boat frame, a hydraulic lifting device is pivotally connected to the front and rear ends of the bracket body, a pushing mechanism is fixed to the bottom of the bracket body, and the pushing mechanism includes a pushing oil cylinder, and the moving end of the pushing oil cylinder is provided with a roller connected to the telescopic bracket. The connecting rod is fixed to the frame, and a supporting device is fixed under the telescopic bracket, the supporting device includes a fixed seat, a support block is provided at the front end of the fixed seat and is in contact with the tail end of the cradle, the support block is an electromagnet, the support block is inserted into the fixed seat, an insulating spring is provided between the energized end inside the fixed seat and the conductive end of the support block, a traction device is provided at the tail end of the bracket body, the traction device includes a roller, a rotating shaft for driving the roller to rotate is inserted axially inside the roller, one end of the rotating shaft is connected to the output shaft of the reduction motor, a steel cable is wrapped around the roller, and a lock is fixed to the movable end of the steel cable.

[0007] Preferably, a slope foot is provided at the front end of the telescopic bracket.

[0008] Preferably, the roller is evenly provided with a plurality of grooves along the outer circumference, and a locking block that can be raised and lowered is provided under the roller, and the locking block rises and extends into the groove to prevent the roller from continuing to rotate.

[0009] Preferably, the cross-sections of the bracket body and the front and rear ends of the telescopic bracket are both V-shaped.

[0010] Preferably, there are two traction devices, which are symmetrically arranged at the tail end of the bracket body.

[0011] A method for using a lifeboat quick installation fixing platform comprises the following steps:

[0012] Step 1: Use the crane at the dock to lift the lifeboat above the bracket body, and place the lifeboat horizontally on the bracket body, with the bow of the lifeboat corresponding to the front end of the bracket body and the stern of the lifeboat corresponding to the rear end of the bracket body;

[0013] Step 2: Lock the locks of the two traction devices to the lifting points on both sides of the lifeboat, lift the locking block under the roller, and insert the locking block into the groove of the roller;

[0014] Step 3: Control the hydraulic lifting devices under the front and rear ends of the support body to lower the hydraulic lifting device at the front end and raise the hydraulic lifting device at the rear end, so that the support body and the lifeboat are tilted as a whole to a set angle;

[0015] Step 4: Start the pushing cylinder to extend the telescopic bracket until the support block of the abutment device below the telescopic bracket contacts the tail end of the davit. The insulating spring between the support block and the fixing seat is compressed, so that the energized end inside the fixing seat contacts the conductive end of the support block and energizes it. The support block made of the electromagnet generates an adsorption force, which tightly adsorbs and fixes the steel davit. At this time, the slope foot end of the telescopic bracket overlaps the tail end of the davit.

[0016] Step 5. Drop the locking block under the roller, start the reduction motor, and slowly release the lifeboat along the bracket body and the telescopic bracket. The rollers inside the guide rails on both sides of the bracket body and the telescopic bracket ensure the smooth sliding of the lifeboat.

[0017] Step 6: When the lifeboat slides into the predetermined position of the davit under the control of the traction device, stop the reduction motor and raise the locking block again to lock the roller and stop it from rotating, keeping the lifeboat stationary and fixing the lifeboat to the davit;

[0018] Step 7: Disconnect the lock of the traction device from the lifeboat, reset the telescopic bracket and the bracket body, and complete the rapid installation and fixation of the lifeboat.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] There is no need to place the lifeboat in the water first and then coordinate with multiple departments to complete the final boat hanging operation. Instead, the lifeboat can be directly hoisted onto the support body using a dock crane. The lifeboat hanging operation can be completed by 1-2 workers. The operation is simple and the boat hanging operation cycle is greatly shortened. At the same time, the positioning of the lifeboat when fixed on the davit is more accurate.
