Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for a tug practice machine, which is capable of variably adjusting the line feeding height position.

(Prior Art) As a tug-of-war training machine, there is a training machine that pulls or pulls out a rope according to the pulling force of the tug of war.

This is a contestant pulling a rope wound around a drum driven by a hydraulic winch, etc., so that it is possible to practice tug of war in a state close to the actual battle even if there is no opponent.

(Problems to be solved by the device) However, in this training machine, the payout height of the rope is always constant, which may give an uncomfortable feeling to the athlete, unlike the actual rope height that changes vertically depending on the tug of war posture.

In other words, in a tug of war, the position of the rope is high during an attack that pulls the rope strongly, and the position of the rope is low when defending, so the position of the rope is also low. I can't switch defensive practice.

The present invention has been proposed to solve such a problem.

(Means for Solving the Problems) Therefore, the present invention is a tug-of-war training machine equipped with a winch drum for winding and unwinding a tug rope, and a rotary drive device for the winch drum, and a roller for guiding the rope. The supporting arm variably supports the vertical position of the roller, the base frame to which the supporting arm is attached, and the connecting means provided on the base frame for connecting to the tug training machine.

(Operation) The height of the rope unwound from the tug-of-war training machine can be adjusted freely by changing the position of the roller that guides the rope. The tug of war height can be adjusted to the optimum position, and the training can be performed in a state closer to actual battle.

(Example) The Example of this invention is described based on drawing. FIG. 1 shows an overall side view of a tug of war practice machine and a rope height adjusting device, and FIG. 2 shows a front view thereof.

A winch drum 2 for winding and unwinding the rope 1 is attached to a pedestal 3 on the training machine body 10. A hydraulic motor 4 as a drive source for driving the winch drum 2
Is provided for transmitting the rotation of the motor to the winch drum 2 via a gear or the like.

The hydraulic motor 4 receives pressure oil supplied from the hydraulic unit, and its rotational speed and rotational trick are controlled so that an arbitrary tug-of-war pattern can be obtained by a control device (not shown) by operating the joystick 7, for example.

Although the pedestal 3 can be freely moved by the wheels 3A, an anchor pin 5 is provided to fix the pedestal 3 at the time of practicing tug of war, and is inserted into a support hole 6A formed in the floor surface 6. It is fixed in that position by doing.

A rope height adjusting device 11 is provided to adjust the height position of the rope 1 unrolled from the training machine body 10. The base frame 12 has a supporting arm 13 attached thereto, and the supporting arm 13 is provided with a guide roller 14 for guiding the rope 1.

In this embodiment, the support arm 13 is provided with two upper and lower guide rollers 14, and the support arm 13 has its base end connected to the connecting shaft 15.
It is rotatably supported by and a damper 17 biased by a spring 16 is connected in the middle.

The base frame 12 is provided with wheels 12A for moving, and a connecting hook 18 as a connecting means for connecting with the training machine body 10.

It is configured as described above, and the operation will be described below.

At the time of practicing tug of war, as shown in the figure, the trainer main body 10 is fixed by an anchor pin 5 so as not to be movable, and a rope height adjusting device 11 is connected in front of it.

The rope 1 is unwound from the winch drum 2 so as to be guided through one of the upper and lower guide rollers 14.

When the tug of war pattern is set by manually operating the joystick 7 of the training machine body 10, hydraulic oil is supplied to the hydraulic motor 4 to control the drive torque of the winch drum 2.

As a result, the pulling force of the rope 1 is strengthened or weakened, so that it is possible to practice tug of war with the same feeling as when the opponent is actually there.

By the way, the height position of the rope 1 is determined by the position of the guide roller 14 of the support arm 13, and when the athlete pulls the rope 1 in a low position, the support arm 13 inclines while compressing the spring 16 in response to this, When lowering the position of the guide roller 14 and pulling the rope 1 at a high position, the guide roller 14 is pushed back by the spring 16 and returns to the high position. Further, the tension angle of the rope 1 also changes the inclination angle of the support arm 13, so that the tug of war practice can be performed as if the opponent were actually there.

Since there are two upper and lower guide rollers 14 in this embodiment, the initial position for hanging the rope 1 can be selected according to the practice conditions.

Next, FIGS. 3 to 5 show other embodiments of the rope height adjusting device 11, respectively.

In the embodiment shown in FIG. 3, the support arm 13A is tilted by the adjusting screw 21, a screw ring 21A is attached to the middle of the supporting arm 13A, and the base end of the adjusting screw 21 is attached to the base frame 12 by the bracket 21B. It is rotatably connected via.

By operating the handle 21C and rotating the adjusting screw 21, the angle of the support arm 13A can be freely changed.

In the embodiment of FIG. 4, instead of the adjusting screw 21, a cylinder 22
The support arm 13B is supported by the base frame 12 so as to be tiltable. Support arm as cylinder 22 expands and contracts
13 angles can be adjusted freely.

In the embodiment shown in FIG. 5, the supporting arm 13C is fixed to the base frame 12 at a predetermined inclination angle, and a locking step portion 23 for locking the guide roller 14 is vertically provided at a predetermined interval. In this case, a plurality of rollers are formed, and the guide roller 14 can be moved if necessary.

(Effect of the device) As described above, according to the present invention, the height of the rope fed from the tug-of-war training machine can be freely adjusted as needed, so that the rope can be attacked or protected as in an actual tug of war. It is possible to set the optimum tug of war height position according to the posture of, and it is possible to perform training in a state closer to actual battle.

The effect is that you can do it.
