Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a towing vehicle for a boat trolley that has excellent directionality during towing.

[Prior art] For example, in a marina, when moving a cart carrying a boat on land between a designated storage area and a lifter that lowers it to the water surface, it was conventionally pushed by hand, but during peak periods in July and August, it was necessary to move it by hand. Moving the boat, which weighs several tons, is quite hard work.

As a means of solving this problem, a trolley equipped with handlebars and a cargo platform that can be raised and lowered was put into production in 1982.
This is proposed by Publication No. -21270.

[Problem to be solved by the invention] When using the cart of the prior art, the boat cart is placed directly on the loading platform, so if the boat tries to change its direction during towing, the cart may slip off the loading platform. There is a problem with this.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a tow truck for a boat truck that can safely and easily tow a boat truck.

[Means for Solving the Problems] The present invention provides a turntable that includes a frame with a handle bar on the front and a platform that can be raised and lowered, a vertically elongated mounting hole on the platform, and a rising wall on one side. It is pivoted into the mounting hole.

[Operation] The cart is placed on a rising wall with one side locked and then towed, and if the direction is changed during towing, the turntable will follow suit and rotate, so the cart will not slip off. do not have.

[Example] Next, an example of the present invention will be described based on the accompanying drawings.

As shown in FIG. 1, a handlebar 1 is protruded from the front of the towing vehicle a so as to be movable up and down, and the tip of the handlebar 1 is provided with a start switch, a forward/reverse switch up/down button 2, and the like. A hydraulic motor for driving the front wheels 3 and a storage compartment 4 for a battery are loaded on the front part of the towing vehicle a. A low-floor loading platform 6 that is raised and lowered by a hydraulic cylinder (not shown) is provided on the upper part of the frame 5 at the rear of the storage section 4, and a turntable 7 is provided at the rear of the loading platform 6.

To be more specific, the turntable 7 is the second
As shown in FIG. A, it is L-shaped with a rising wall portion 7a, and a shaft 7b is provided at the bottom, and the shaft 7b is inserted into the mounting hole 6a of the loading platform 6 and is rotatable. Note that 7c is oil and fat applied to the bottom surface.

FIG. 2B shows a second embodiment of the turntable, in which the shaft 8b of the L-shaped turntable 8 having an upright wall portion 8a is fixed to the loading platform 6 through a mounting hole 6a.
It is inserted into a sleeve 6b forming a rotatable member.

Then, the lower frame of the truck b loaded with the boat is advanced to the rising wall portion 7a of the turntable 7 and is locked therein. Next, by pressing the lift button 2, the hydraulic pump is started and the loading platform 6 is raised by the hydraulic cylinder. With this, trolley b
The casters of are lifted off the ground, and the cart b is placed on the loading platform 6. Next, by tilting the handlebar 1 toward you and operating the forward switch 2, the hydraulic motor is driven and the vehicle is towed. When turning, the towing vehicle a changes direction by moving the handlebar 1 from side to side, and the turntable 7 rotates as shown in FIG. 3, thereby gradually changing the direction of towing the truck b.

After being towed to a predetermined location, the lifting button 2 is operated to lower the loading platform 6 to ground the casters of the truck b, and the towing vehicle a is pulled out.

Although the embodiments of the present invention have been described in detail above, it goes without saying that the present invention is not limited to the above embodiments and includes various modifications within the scope of the gist of the present invention.

As explained above, in the present invention, the turntable 7 is provided on the platform 6 of the towing vehicle a, which can be raised and lowered, so it is possible to tow in a narrow space in a generally perpendicular direction. Even if you change the position, trolley b will not slip and can be used with confidence.

Furthermore, by forming a rising wall part 7a on the turntable 7, when inserting the carriage b, the lower frame of the carriage b is stopped at a fixed position by the rising wall part 7a, and the carriage b is always pulled at the fixed position. You can do the work easily.

Furthermore, in the embodiment, since it is battery-driven, there is no exhaust gas and it can be used safely even in a boathouse.

[Effects of the invention] The present invention provides a loading platform that can be raised and lowered on a frame equipped with a handlebar at the front, a mounting hole is provided vertically in the loading platform, and a turntable with a rising wall section on one side is attached to the mounting hole. The turntable can be used to safely tow the boat's cart, and the turntable is provided with an upright wall, making it easy to position the boat's cart.
