Abstract

PURPOSE:To improve the safety by supporting the hull automatically while extending a rod through utilization of the weight of a ship thereby automatizing the supporting of ship in the sea water. CONSTITUTION:When the sea water level lowers at low tide, the keel section 29 is mounted on a central receiving board 5 to lower the longitudinal shafts 3, 3' due to the weight of a ship, thereby the racks 6, 6' will engage with the pinions 7, 7' to rotate the arm rods 9, 9' upwardly thus to draw the rod 15 of the supporting rod tubes 28, 28' obliquely upward. The rod 15 will lift while the pinions 17, 17' in a fork boards 16, 16' at the lower end are being engaged with the racks 14, 14' on the inner face of a holding tube 11, then a seat 25 at the upper end of the rod 15 will joint with the hull lower face of the keel section 29 to press a spring 27 in the opposite direction with the lifting rod 15.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ship support device installed on a bogie for hoisting a ship at a shipyard or the like. Conventionally, when a ship is unloaded at a shipyard or the like for repairs, etc. After the ship is pulled to the position of the cart, wedges and sandbags are piled up between the ship's belly and the cart to support the ship's belly, and then the cart is lifted onto land using a winch. However, it takes time and effort to support the ship's belly by taking into consideration the ship's swaying, etc. in seawater, and to balance it from front to back and side to side, making the work difficult and dangerous when the sea is stormy or the wind is strong. Even in winter, the work tends to be difficult due to the cold weather, and the work time is limited by the ebb and flow of the tide, which requires skill.

In order to solve the above-mentioned problems, the present invention is a device that automatically supports the hull of a ship while extending the rod by utilizing the load of the hull, which automates the support of the hull in the sea. It is characterized by the ability to improve safety and efficiency during work.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

Fix the box 2 at the center of the upper surface of the horizontally long base l,
A vertical shaft 3 passes through the base 1 on both sides of the box 2,
31 is loosely fitted and elastically supported by springs 4, 4I, and the central support plate 5 is fixed to the upper surface of the vertical shafts 3, 31, and a rack 6.61 is mounted outside the vertical shaft 3° 3' in the box 2. Rotating shafts 8, 81 with fixed pinions 7.71 that mesh with the rack 6.61 on the outside of the vertical axis 3° 31 are mounted on both sides of the box 2, and the lower end is bifurcated. Fix the arm rods 9, 91 to the rotating shafts 8, 8' and move them to the box 2.
The arm rods 9, 91 project obliquely upward from the openings on both sides.
Spring 10.10' is attached to the center of the box 2 and the top surface of the box 2.
A hinge fitting 12 is provided protruding from the lower surface of the holding cylinder 11 which is stretched, and the front and rear sides are opened, and a shaft hole 13 is opened at the upper surface, and racks 14 and 14' are carved on the inner surfaces of both sides of the holding cylinder 11. At the lower end of the rod 15 fitted into the upper shaft hole of the holding cylinder 11, there is a bifurcated plate 16°16 fitted into the front and rear openings of the holding cylinder 11.
' are vertically installed, and two pinions 17.17 are engaged with racks 14.14' on the inner surfaces near the lower ends of the two-pronged plates 16, 16'.
A bracket 21 is fixed via a spring 20 to the lower end of an operating shaft 19 which is fitted into a core hole 18 provided in the center of the rod 15, and a bifurcated plate 16 at the lower end of the rod 15.
．． The bracket 21 is inserted into the vertical hole 22 and 22' provided at 16'.
and insert the binions 17, 17 into the bracket 21.
A stop gear 23 that engages with the rod 15 and stops the lowering of the rod 15 is pivotally supported, a long hole 24 communicating with both sides is formed in the upper end of the rod 15, and a catch seat is loosely fitted to the upper end of the rod 15. 25 and the upper end of the operating shaft 19 through the elongated hole 24 and the pin 26
A support rod cylinder 28 is formed with a spring 27 interposed between the catch 25 and the seven flange of the rod 15, and a pair of left and right support rod cylinders are connected at an appropriate interval from both sides of the box 2 of the base 1. 28. The lower end of 2'8' is pivotally connected to the base 1, and the upper end of the arm rod 9, 91 is pivotally connected to the inner surface of the upper end of the rod 15 of the left and right support rod cylinders 28, 28'. 0 In the figure, 29 indicates the keel portion of the hull.

Next, the effects of the present invention will be explained with reference to figures of one embodiment.

The hull support device of the present invention is installed on the upper surface of two sets of front and rear bogies for transporting the ship's body to land. is towed so that the lower keel part 29 faces the center backing plate 5, and when the sea water ebbs and the sea level falls, the keel part 29
is placed on the center support plate 5, and due to the load of the hull, the vertical axis 3.3
When ' is lowered, the pinion 7.71 engages with 2-7-p6, 6' of the vertical shaft 3.31, the pinion 7.71 rotates, and the arm rods 9, 91 rotate upward. , support rod tube 2
8, 28' to pull out the rod 15 obliquely upward. The rod 15 is connected to the rack 14.14' on the inner surface of the holding cylinder 11 by the pinion 17.17' in the forked plate 16°16' at the lower end.
The seat 25 at the upper end of the rod 15 joins the lower surface of the hull of the keel part 29 and presses the spring 4 ring 27 in the opposite direction to the rod 15, which rises while engaging with the keel part 29.
9 descends, the stop gear 23 in the bracket 21 hanging down via the spring 20 moves to the pinion 17.
17' to prevent the rotation of the pinion 17.17', the left and right support rod cylinders 28.2
8' is supported via a seat 25 at the upper end.

Therefore, the ship's hull can be automatically supported by converting the downward load pressure into the vertical movement of the rod using the principles of rack-binion and lever, and the operator does not have to go into the seawater. This can improve safety and efficiency during work. Conversely, when the hull rises to the sea surface and the load on the center support plate 5 is removed, the center support plate 5 rises with the return elasticity of the springs 4 and 4', and the arm rods 9 and 91 do not rotate downward. Since the load is also removed from the catch seat 25, the stop gear 2
3 dissociates upward, and the rod 15 descends into the holding cylinder 11. This provides the remarkable effects described above.
