Description

[Detailed Description of the Invention] The present invention relates to a transport vehicle equipped with a battery that supplies power to a propulsion drive motor, a control circuit, and the like.

In this type of transport vehicle, a transported object support section is provided on the cart, but in conventional transport vehicles, the battery is mounted inside the cart, that is, below the transported object support section, or Alternatively, it is mounted on either the front or rear of the conveyed object support section, or both. When the battery is mounted below the object support part as in the former case, the object support part becomes higher and the center of gravity becomes higher when the object is loaded, resulting in a decrease in stability. It is particularly unsuitable for use as a transport vehicle for transporting heavy objects. In addition, when the battery is mounted at the same level as the object support part as in the latter case, the object support part can be installed at a lower position, but the overall length of the transport vehicle becomes longer, making it difficult to use the storage line. Floor usage efficiency decreases.

The present invention aims to solve these conventional problems, and one embodiment thereof will be described below with reference to the attached illustrative drawings.

Reference numeral 1 denotes a truck, each of which has a drive motor 2a,
A pair of left and right drive wheels 3a, which are driven in forward and reverse directions by 2b;
3b is provided at the center, and a pair of left and right swivel wheels (casters) 4, 5 are provided at both front and rear ends. Reference numerals 6 and 7 denote conveyed object support sections provided at two locations on the front and rear sides of the truck 1, and are provided with driving roller conveyors 9 and 10, respectively, which can take in and take out the conveyed objects 8 in the lateral direction.

Reference numeral 11 denotes a battery mounting section, which is provided at the center of a support base 12 that covers the upper sides of both the transported object support sections 6 and 7. This support stand 12 is formed between a side wall 13 that is erected from the cart 1 on the opposite side of the object support sections 6 and 7 from which the object is taken in and taken out, and a side wall 13 located between the object support sections 6 and 7. Box-shaped parts 15 and 16 are provided at the front and rear of the battery mounting part 11, and are supported by a partition wall 14 erected from the trolley 1 at the same position. The battery mounting section 11 has a box-like structure with an open upper side (an opening/closing lid may be provided if necessary), and a terminal connected to an electrode of a battery 17 mounted at a predetermined position is provided inside. The terminal is provided so that power can be supplied to required locations (power circuits for the drive motors 2a, 2b, drive roller conveyors 9, 10, etc., control circuits, etc.) through this terminal. or,
The battery 17 is provided with a hook 18 that can be used during lifting and transportation.

Note that the number of conveyed object support sections is not limited. or,
The conveyed object supporting section may be equipped with a conveyed object supporting means adapted to the form of the loaded conveyed objects, the method of loading and unloading them, etc., and is not limited to a drive roller conveyor.

The battery-equipped conveyance vehicle of the present invention can be implemented as described above, and includes a conveyed object support section provided on the cart, and a battery mounting section provided above the conveyed object support section. Therefore, the height of the object support section above the floor surface can be lowered compared to the case where the battery mounting section is provided below the object support section. Therefore, the center of gravity when loaded with objects to be transported is lowered, and even heavy objects can be transported safely.

In addition, the overall length of the vehicle is shorter than when the battery mounting section is installed in parallel at the front and rear of the transported object support section, which makes it possible to increase the efficiency of floor space utilization in storage lines, etc. The turning radius is also smaller. Furthermore, according to the configuration of the present invention, the transported object support section is provided with a transported object support means that supports the transported object so that it can be taken in and taken out in left and right directions, so that
Even if the distance between the transported object supported by the transported object support section and the battery mounting section is made sufficiently narrow to make the height of the entire vehicle including the battery mounting section as low as possible, The object to be transported can be taken in and out relatively easily by using the object supporting means. In other words, since there is no need to provide a wide space between the object to be transported supported by the object support section and the battery mounting section, the height of the entire vehicle including the battery mounting section can be configured to be low. I can do it.

Furthermore, since the battery mounting section provided above the conveyed object support section allows the battery to be taken in and out vertically up and down, it is necessary to put in and take out the battery supported at a relatively high place horizontally and horizontally. Batteries can be easily and easily loaded and unloaded using chain blocks, etc., compared to the case where batteries are not loaded or unloaded.
