Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for connecting a truck moving on a rail to a preceding or following vehicle.

[0002]

2. Description of the Related Art It is usual for an operator to push a trolley, which is transported on a rail, one by one. In this truck, when the operator releases the truck, the wheels are automatically braked. This brake device is known, but its structure is shown in FIG. 3 for convenience of explanation of the operation of the present invention. The lever L has a structure in which one end is pivotally connected to the edge of the vehicle, and the cam C is rotated by the tension of the spring S in a state of being constantly lifted from the same edge, and the brake shoe is spread to brake.
When the operator pushes the lever L against the tension of the spring S, the brake shoe returns to the original position and the brake is released.
The minecart can run. This device is provided on one of the front and rear wheels, or on each of the left and right wheels alternately or in other combinations, and a pair of levers L are mounted on the front and rear ends of the trolley, but the device has a common intermediate shaft M. Therefore, the front and rear levers L operate in the same manner regardless of which one is pressed.

[0003] At the site, two or more trucks are connected and pushed or used by being connected to an automobile (towing vehicle). These were connected by a connecting rod. However, since the vehicle to be connected is in a braking state, it is necessary to bind the brake lever L to the frame with a rope or the like and release this. There has been a demand for a connecting device that can easily release the connection.

[0004]

The facing edges of the minecart and the preceding or succeeding vehicle are connected by an easily detachable connecting rod, and the lever L can be pressed by a pressing rod integrally attached to the side of the connecting rod. That is, when the connecting rods are connected, the brake is released at the same time.
In the case where the rail is a curved road, the length of protrusion of the pressing rod is made adjustable.

Since the connecting rod is simply provided with the pressing rod, it is lightweight and easy to attach and detach. In the case of connecting multiple trucks, remove the trucks in the case of going backwards, and re-attach them with the right and left.

In some cases, a car that can run on rails appears and a large number of trucks are connected and transported. In this case, the present device is used between the car and an adjacent truck. If the connecting rod is disengaged due to an accident, the pressing rod separates from the lever, and the truck automatically brakes and stops.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In this apparatus, as shown in FIG. 1, a side rod 2 is protruded near one end of a connecting rod 1, and a pressing rod 3 is provided near a free end of the side rod so as to be able to be adjusted. FIG. 1 shows a case where a truck B is connected to the front of a truck A and an operator pushes the truck B to the left. Lever L has handle 1 for operator's convenience
Is provided. The lever L before the connection is raised to the position indicated by the dashed line. However, when the lever L is connected by the connection rod 1, the lever L is pressed to the position indicated by the solid line and the braking is automatically released. When the worker releases the truck at the destination, the truck A is automatically braked and both the trucks A and B can be stopped, so that no problem occurs on a large number of gradient roads.

[0008]

[Effect] By using this device which is lightweight and easy to handle, 2
In the case of connecting more than one truck, the connecting operation becomes remarkably easy.
