The present invention relates to a trolley for opening and closing the doorway bellows, and more particularly, to automatically open and close the bellows installed at the doorway of a factory or a large building.

In general, doorways of factories or large buildings, which are frequently passed by vehicles, are easy to open and close and use bellows that can act as walls when closed.

Conventionally, a guide rail is installed on the ground, and a plurality of inverted U-shaped struts are rotatably installed while the wheels are moved while receiving the guide rails. When a pair of movable pieces were installed to cross each other, the doors were opened when the doors were narrowed when the doors were opened, and the doors were closed when the doors were widened when the doors were closed.

However, when a user wants to open and close the doorway of the conventional doorway opening and closing Java, a person must push the support and when the size of the doorway is large, several people must push the support at the same time. In bad weather, there was a problem that the door opening and closing work is not made smoothly.

The present invention has been devised to solve the above problems, by installing a trolley moved by the drive of the motor on one side of the doorway bellows and opening and closing the doorway bellows by moving the bellows installed at the doorway as the cart moves. The object is to provide an entrance bellows opening and closing trolley to facilitate.

The structure of the present invention doorway bellows opening and closing trolley for achieving the above object is a motor fixed to the upper surface of the plate installed inside the main body, a drive unit fixed to the upper inside of the main body to drive the motor, and to operate the drive unit In order to reduce the driving force generated in the motor, a switch fixed to the outside of one side of the main body, a reducer is fixed to the bottom of the main body connected to the belt and the motor, and a clutch for cutting off the power transmitted to the reducer A reduction shaft, driven shafts that receive power transmitted to the reduction shaft and are rotated, and wheels for moving the main body are fixed to both sides, and installed on the front and rear of the main body to determine the moving distance of the main body. It consists of an infrared sensor.

In the above configuration, a stopper is installed at both sides of the entrance and is connected thereto, and a limit switch for stopping the movement of the main body is installed on one side of the bottom surface of the main body so as to correspond to the stopper, or the upper part of the main body is turned on when the main body is moved. It is more preferable to install an alarm lamp.

Therefore, according to the door bellows opening and closing trolley of the present invention according to the above configuration, the bellows opening and closing the door is automatically opened and closed by the drive of the motor to simplify the opening and closing work of the doorway, as well as in the climatic conditions difficult to identify the front The effect is to be able to reliably identify the movement.

EXAMPLE

Example 1

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 3.

1 is a perspective view of a state in which a portion of the opening and closing trolley according to the present invention is cut away, Figure 2 is a longitudinal cross-sectional view of the opening and closing trolley according to the present invention, Figure 3 is the opening and closing trolley according to the present invention opens and closes the entrance bellows As a state diagram, a door 20 having a handle 22 is fixed to a front side of the main body 10 so as to rotate about a hinge 21 on one side thereof, and an upper surface of the plate 11 installed inside the main body 10. The motor 30 generating the driving force is fixed thereto, and a driving part 40 for driving the motor 30 is installed at an inner upper portion of the main body 10.

In addition, a switch 41 for manipulating the driving unit 40 is installed outside one side of the main body 10, and a speed reducer 50 for reducing driving force generated in the motor 30 is provided on the bottom of the main body 10. ) Is installed and the motor 30 and the reducer 50 are connected by a belt 31.

On the other hand, the reduction shaft 51 installed on one side of the reducer 50 includes a clutch 52 that can cut off power, and the driven shaft 60 in which the wheels 61 are fixed to both sides on the bottom of the main body 10. It is rotatably installed and the driven shaft 60 and the reduction shaft 51 are connected to each other by a chain (62).

In addition, an infrared sensor 70 is installed at the front and rear of the main body 10 to maintain a constant moving range of the main body 10, and at one side of the main body 10 for operation by a remote controller (not shown). A remote controller receiver for receiving a signal generated by the remote controller and a reception antenna 80 for transmitting the signal to the driver 40 are provided. In addition, the alarm lamp 90 that is turned on when the main body 10 moves on the upper surface of the main body 10 to check the movement of the truck even when it is snow or rain, or when the visibility distance is short, such as in the fog or night, which is difficult to identify ahead. It is more preferable to install.

According to the present invention configured as described above, in order to close the door in the state in which the door is opened as shown in FIG. 3 (a), when the forward switch is pressed in the switch 41 installed on the side of the main body 10, the switch 41 By the drive unit 40 to rotate the motor 30 in the forward direction and the rotational force generated in the motor 30 is transmitted to the reducer 50 through the belt 31 and the rotational force transmitted to the reducer 50 Is decelerated at a constant rotational speed and output to the reduction shaft 51.

The rotational force output to the reduction shaft 51 is transmitted to the driven shaft 60 through the chain 62 installed on the reduction shaft 51 and the rotational force transmitted to the driven shaft 60 is fixed to both sides thereof. The wheel 61 is transferred to 61 to guide the guide rail 101 installed on the ground 100 to move the bogie A.

Therefore, when the trolley A is moved, the reverse U-shaped strut 102 installed in the trolley A is moved together, and the movable piece 103 provided between the respective struts 102 rotates about the hinge 104. As the spacing between the struts 102 becomes wider, the doorway is closed.

And when opening the closed doorway it will be understood that the motor 30 is rotated in the reverse direction by pressing the reverse switch installed on the side of the main body 10 to open the doorway.

In addition, when a person wants to push the cart A by hand due to a failure or power failure of the cart A, the door 20 is pulled by pulling the handle 22 of the door 20 installed at the front of the main body 10. Opening and pushing the clutch 52 included in the deceleration shaft 51 to one side allows the driven shaft 60 to be idle, so that the main body 10 can be moved with a small force.

Example 2

When described in detail with reference to Figure 4 of the accompanying drawings showing another embodiment of the present invention. 4 is a side view of the vehicle according to another embodiment of the present invention installed at the doorway, and a pair of stoppers 71 are installed on both sides of the guide rails 101 and protrude upward. If the limit switch 72 is installed on the bottom of the main body 10 so as to correspond, the cart A moves and the bogie A stops when the limit switch 72 is connected to the stopper 71. You can move a certain distance.

As described above, the present invention is a very useful design that makes it easy to open and close the door by opening and closing the bellows that open and close the doorway by driving the motor, and to reliably identify the movement of the vehicle even under difficult climatic conditions. to be.
