Description

[Detailed description of the invention] [Industrial application field] This invention relates to an electric transport trolley used for transporting various types of cargo in factories or other places.

[Conventional technology]

Conventionally, as an electric transport trolley, a battery is installed on one side in the front and back direction inside the body of the body which has running wheels and is open at the top, and a driving drive device and a battery are installed on the other side in the front and rear direction inside the body of the body. An electric transport trolley is known which is provided with a wheel direction adjustment device and has a structure in which a loading platform lid is placed in an opening of the trolley body and fixed with a large number of screws.

[The problem that the idea aims to solve]

However, when charging the battery or inspecting the traveling drive device or wheel direction adjustment device of this electric transport vehicle, it is necessary to unscrew the numerous screws that secure the cargo platform lid and then remove the cargo platform lid. Furthermore, after completing charging and inspection, the loading platform lid must be secured by screwing together a large number of screws, so it takes a long time to attach and remove the loading platform lid during charging and inspection, and there is also damage inside the truck itself. Even if you are only charging the battery on one side of the truck in the front and rear directions, or inspecting the traveling drive device or wheel direction adjustment device on the other side of the truck body, many screws may come off and the heavy Since the entire loading platform lid must be removed, there are problems in that it takes a long time and requires a relatively large amount of labor.

The object of this invention is to provide an electric transport trolley that can advantageously solve the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above object, in the electric transport trolley of this invention, a battery 2 is installed on one side in the front and back direction inside the trolley body 1 which has running wheels and has an open top. In an electric transport trolley, a traveling drive device 3 and a wheel direction adjustment device 4 are provided on the other side in the longitudinal direction of The rear end of the lid 6 is pivotally attached to form a foldable loading platform lid 7, which is removably fitted and locked into the opening of the truck body 1, and is attached to the rear end of the rear lid 5. A semicircular handle 20 is inserted into an elongated hole 19 provided at the front of the front lid 6, and the center of the straight portion of the handle 20 is connected to a horizontal shaft 21 with respect to a bracket fixed to the bottom surface of the lid. Pivotally mounted, handle 20
The straight portion of the handle 20 is arranged so as not to protrude from the top surface of the lid when the handle 20 is held with the semicircular portion facing downward due to its own weight.

In addition, the groove bottom plate of the groove-shaped metal fitting 14 in the locking tool 16 is fixed to a bracket fixed to the truck body 1.

The front end of the metal rear lid 5 having a flat top surface and the rear end of the metal front lid 6 having a flat top surface are connected by a pivot fitting 17 fixed to the bottom surfaces of the lids by welding. The folding platform lid 7 is configured by being pivotally connected to be rotatable in the vertical direction, and the pivot fitting 17 thereof is provided with a pivot shaft 18 extending in the left-right direction.

A semicircular handle 20 is inserted into the elongated hole 19 provided in the rear part of the rear lid 5 and the front part of the front lid 6, and the vicinity of the center of the straight part of the handle 20 is fixed to the lower surface of the lid. It is pivotally attached to the bracket by a horizontal shaft 21, and as shown in FIG. 8, when the handle 20 is held with its own weight with the semicircular part facing downward, the straight part of the handle 20 extends from the top surface of the lid. If the handle 20 is arranged so that it does not protrude, and if the handle 20 is to protrude from the upper surface of the lid, by pressing one end of the handle 20 and rotating the handle 20,
The other end of the handle 20 is made to protrude from the upper surface of the lid, and then the other end is grasped and the handle 20 is rotated to the position shown in FIG. 9.

An insertion engagement metal fitting 22 having an engagement head at the lower end is fixed to the lower central rear surface of the rear lid 5 and the lower central front surface of the front lid 6, and the folding platform lid 7 is connected to the opening of the truck body 1. At the same time, the rear lid 5 and the front lid 6 are each placed on a plurality of lid supporting members 11, and the insertion engagement fittings 22
is inserted between the pair of locking rollers 15 in the locking tool 16.

A forward stop soft bumper 23 is attached to the front end of the truck body 1, and backward stop soft bumpers 29 are attached to both left and right sides of the rear portion of the truck body 1, and a key switch 24, A manual operation operation section 28 is provided, which includes an emergency stop switch 25, a manual operation lever 26, an operation panel 27, etc., and the manual operation lever 26 switches the transport vehicle between forward and backward traveling directions and controls the forward traveling wheels 9. direction adjustment is performed.

When implementing this invention, the means for removably fixing the folding platform lid 7 to the truck body 1 include the locking tool 16 and the insertion engagement tool 2.
2 may be replaced with a magnetic adsorption tool.

[Effect of idea]

According to this invention, a battery 2 is installed on one side in the front and rear directions of a bogie body 1 which has running wheels and is open at the top, and a running drive device 3 is installed on the other side of the body 1 in the front and back direction. In the electric transport vehicle, which is provided with a wheel direction adjustment device 4 and a cargo platform lid provided at the opening of the vehicle main body 1, the rear end of the front lid 6 is pivotally connected to the front end of the rear lid 5. A foldable loading platform lid 7 is constructed, and the folding loading platform lid 7 is removably fitted and locked into the opening of the truck main body 1, so that the folding loading platform lid 7 can be simply lifted or the opening of the truck main body 1 can be opened. By fitting the foldable loading platform lid 7 into the opening of the truck body 1, the folding platform lid 7 can be easily and quickly attached to and removed from the opening of the truck body 1 to perform a general inspection or cleaning of each device inside the truck body 1. In particular, in the case of this invention, a semicircular handle 20 is inserted into the elongated hole 19 provided in the rear part of the rear lid 5 and the front part of the front lid 6, and the straight part of the handle 20 Near the center of the handle 20 is pivoted by a horizontal shaft 21 to a bracket fixed to the bottom surface of the lid.
When the handle 20 is held so that the semicircular part is on the lower side due to its own weight, the straight part of the handle 20 is arranged so that it does not protrude from the top surface of the lid. The handle 20 does not protrude from the top surface of the loading platform lid 7 when it is fitted and locked to the loading platform lid 7. Therefore, when placing cargo on the loading platform lid 7, the handle 20 does not get in the way, and the battery 2 or when it becomes necessary to charge
When it becomes necessary to inspect, clean, etc., you only need to open and close either the rear cover 5 or the front cover 6, so you can easily open and close only the necessary parts with relatively little effort. In addition, effects such as being able to quickly open and close the battery for charging, inspection, cleaning, etc. can be obtained.
