Description

  The present invention relates to a forklift.

  In general, reach-type forklifts, counterbalance-type forklifts (hereinafter referred to as “forklifts”), and the like are known as vehicles used for carrying luggage. Furthermore, it is also known that forklifts use engine-type forklifts that use an internal combustion engine as a power source and battery-type forklifts that use an electric motor as a power source.

  In recent years, the ratio of battery-type forklifts using an electric motor driven by electric power supplied from a battery mounted on a vehicle body of the forklift as a power source is increasing. To lower the center of gravity of this battery-powered forklift and ensure stability, a battery that is larger and heavier than other equipment is placed near the bottom of the vehicle body between the front and rear wheels. The arrangement method has been proposed so far (see, for example, Patent Documents 1 and 2).

  As described above, when the battery is placed at a position between the front wheel and the rear wheel in the vehicle main body and dropped to the bottom surface of the frame of the vehicle main body, it is used for other equipment mounted on the forklift, such as cargo handling and steering. There has been a problem that the arrangement space of the hydraulic equipment and the controller for controlling them is limited by the battery.

As a method for solving this problem, a configuration in which a part of the other devices described above is arranged in a space below the floor in front of the battery and the remaining devices are arranged separately in the space behind the battery can be considered.
In addition, Patent Document 1 proposes a configuration in which the other devices described above are disposed in a space below the floor in front of the battery by reducing the arrangement of hydraulic devices, controllers, and the like. In Patent Document 2, a configuration in which an oil tank or the like is arranged in a space inside the step protruding left and right of the vehicle main body, which is a space different from the space under the floor in front of the battery, to widen the arrangement space of these devices. Has been proposed.

Japanese Patent Laid-Open No. 2001-130885 JP 2005-350197 A

  In general, the oil tank stores an amount of oil necessary for the operation of the hydraulic equipment, and therefore needs to have a tank volume equal to or greater than a specified value. However, if other devices are compactly arranged in the space below the floor in front of the battery as in Patent Document 1, the space in which the oil tank is arranged also becomes small, and the space necessary for the arrangement of the oil tank can be secured. It becomes difficult. That is, there is a problem that it is difficult to secure the required volume of the oil tank.

  In Patent Document 2, since the oil tank is disposed in the space inside the step that protrudes to the left and right of the vehicle body, which is a space different from the space under the floor, the arrangement of the oil tank is compared with Patent Document 1. It becomes easy to secure the necessary space.

  On the other hand, if the oil tank arrangement space, in other words, the shape of the oil tank is made so that other equipment must be removed when the oil tank is replaced, There was a problem that it took time to install and remove the tank.

  The present invention has been made to solve the above-described problem, and provides a forklift that facilitates securing a tank arrangement space and can improve workability when replacing a tank. With the goal.

In order to achieve the above object, the present invention provides the following means.
A forklift according to the present invention includes a tank that stores a liquid necessary for steering or driving the forklift, and a vehicle body that stores equipment including the tank in an internal space. The vehicle body is a tank in the internal space. An opening part that opens a part on the upper side of the storage space, and a first restriction part that restricts a movement of a predetermined amount or more in a direction directly above the tank in the other part on the upper side of the storage space, Have.

The internal space is provided with a second restricting portion that restricts movement of the tank in the lateral direction by a predetermined amount or more around the lower side of the open portion in the storage space.
The tank has a first upper surface that faces the open portion and a second upper surface that faces the first restricting portion in the storage state in the internal space, and the first restricting portion and the second restricting portion. A non-interfering shape that does not interfere with the first restricting portion and the second restricting portion when taking out from the opening portion in a state where movement of a predetermined amount or more in the upward direction and the lateral direction is restricted by each restricting portion. It is characterized by being.

  In the forklift of the present invention, by disposing the tank below the opening portion and the first restricting portion, compared to the case where the tank is disposed below only one of the opening portion and the first restricting portion, A tank that secures the required volume can be arranged.

In addition, when the tank is taken out from the open portion in a state where movement in the above-described directions is restricted by the first restricting portion and the second restricting portion , other devices and members (first and second restricting portions) ), The tank can be replaced without removing other equipment.

Therefore, according to the forklift of the present invention, it is possible to easily secure the space for disposing the tank and improve workability when replacing the tank.
The liquid stored in the tank may be oil used for handling and steering a forklift, or may be supplementary water for a battery mounted on a battery-type forklift, or fuel for an engine-type forklift. There is no particular limitation on the application and type.

  In addition, the shape of the tank may be such that the first upper surface and the second upper surface are formed at the same height, or the first upper surface and the second upper surface may be formed at different heights. For example, when the first restricting portion is disposed at a position lower than the open portion, the first upper surface is formed in a step shape in which the first upper surface is higher than the position of the second upper surface. Since the upper surface protrudes, a tank having a required volume can be arranged as compared with the case where such an upper surface protrusion is not provided.

  For example, when the first upper surface is formed in a stepped shape higher than the position of the second upper surface, the bottom surface and the side surface are substantially L-shaped below the first upper surface as viewed from the side. May be. In this case, if the upper surface is not provided with a stepped shape, if the shape can secure a larger volume, for example, the first upper surface is rotated obliquely upward on the first restricting portion side to allow the tank to move to the inner space. In order to avoid interference, it may be arranged away from other devices and members.

However, it is desirable to arrange the tank as close as possible to other devices and members because it is easy to secure the necessary volume.
In consideration of this point, in the above invention, the tank preferably has a cut-out surface in which a corner portion connecting the side surface and the bottom surface is cut out below the first upper surface.

  When the notched surface is formed in this way, when the tank is moved in the internal space, the corner of the tank can be prevented from interfering with other devices and members, and other devices can be used. By arranging them close to the members, it is possible to secure a larger volume of the tank.

  In other words, such a notch surface is, for example, on the outer surface when viewed from the center of rotation when the tank is moved in the internal space by rotating the first upper surface obliquely upward on the first regulating portion side. It is desirable to be provided. Thereby, it is possible to avoid interfering with the second restricting portion (the portion that restricts movement of the tank in the lateral direction by a predetermined amount or more around the lower side of the open portion in the storage space), and the first A relatively large capacity of the tank can be ensured by arranging it in proximity to other devices as the second restricting portion.

In such a tank, the notch surface is preferably notched into a curved surface.
Such a cut-out in the curved surface is advantageous in that a larger capacity of the tank can be secured as compared with a case in which the cut-out is made in the flat surface .
Moreover, it has the pressing member which presses a tank up and down, and the recessed part for fixing a pressing member may be formed in the tank.

In the tank, for example, if the first upper surface only be formed higher than the position of the second upper surface, forming a portion for connecting the side and the second upper surface below the first top curved surface It is, in other words, for example, music surface on the inner surface as viewed from the rotation center for moving the tank a first upper surface is rotated obliquely upward of the first regulating portion side in the internal space is formed Even better.

  In this case, without interfering with the first restricting portion (a portion that is disposed at a position lower than the open portion and restricts movement of a predetermined amount or more in the upper direction of the tank in the other portion on the upper side of the storage space). The tank capacity can be ensured more by arranging it close to the first restricting portion.

  Next, considering the point of improving the workability at the time of tank replacement, in the above invention, a reference member for determining the installation position of the tank is provided in the internal space. It is preferable that a guide member that is loosely fitted to the reference member and moves along the reference member when the tank is stored in the storage space is provided.

  By providing the guide member on the side surface of the tank in this manner, the operator can loosely fit the guide member so that the movement of the tank is guided to the installation position in the internal space. Easy to install. In other words, the operator can easily remove the tank from the opening while rotating the tank along the guide member.

  In the above invention, the opening portion is a part of a floor constituting a floor surface of a driver seat of the forklift, and the first restricting portion protrudes left and right of the vehicle main body and has an upper surface higher than the floor. It should be a low step part.

  By arranging the tank across a part of the space below the floor and the inside of the step portion in this way, it is possible to easily secure a space of a size necessary for tank arrangement in the limited internal space of the vehicle body. it can.

Compared to the case where the upper surface protrusion 68 is not provided, the oil tank 61 having a required volume can be arranged in the internal space 11 of the vehicle body 10.

  Further, when the oil tank 61 is moved while being rotated from the internal space 11 (taken out from the opening / closing part 19), other devices and members (the controller 82, the hydraulic motor 71, the traveling motor 21, the partition part 15, and the upper surface) By forming it in a non-interfering shape that does not interfere with 16a), it is possible to avoid removing these other devices and members when replacing the tank.

  Therefore, it is possible to easily secure the arrangement space of the oil tank 61 and improve workability when the oil tank 61 is replaced. And by arranging the oil tank 61 straddling part of the space under the floor of the driver's seat 40 and the inside of the step portion 16 in this way, it is necessary for tank arrangement in the limited internal space 11 of the vehicle body 10. It is possible to easily secure a large space.

  Moreover, the oil tank 61 has the notch surfaces 62c and 62d cut out along the rotation direction at the time of passing the storage space in the internal space 11, as shown in the said embodiment. Thus, when the oil tank 61 is moved while rotating from the internal space 11, the corners of the oil tank 61 can be prevented from interfering with other devices and members, and other devices and members can be used. By arranging them close to each other, a larger volume of the oil tank 61 can be secured.

  Further, by providing the grip portion 91 on the upward projecting surface 62a of the overhang portion 62 in the oil tank 61, the operator can easily hold the oil tank 61 when the oil tank 61 is exchanged. Workability at the time of replacement of the tank 61 can be further improved.

  For example, the oil tank 61 of the above embodiment has the first notch surface 62c and the second notch surface 62d, but is not limited to this, and has these notch surfaces 62c and 62d. It may be formed in a substantially L shape. In this case, the shape may be a shape that can secure a larger volume than the case where the front protruding surface 62 b is not provided on the upper surface of the oil tank 61, and interference occurs when the oil tank 61 is moved while rotating from the internal space 11. In order to avoid this, it may be arranged away from other devices and members. However, it is desirable to arrange the oil tank 61 as close as possible to other devices and members because it is easy to secure a necessary volume.

  Furthermore, in the oil tank 61 of the above embodiment, the upward projecting surface 62a of the overhanging portion 62 is formed higher than the position of the upper surface 64a of the tank body 64, but the present invention is not limited to this. The surface 62a and the upper surface 64a may be formed at the same height, or the upper protruding surface 62a may be formed lower than the upper surface 64a. Even in such a mode, when the oil tank 61 is disposed below the opening portion 19 and at the step portion 16, the oil tank 61 is disposed only below either the opening portion 19 and the step portion 16. In comparison with the oil tank 61, the oil tank 61 having a necessary volume can be arranged.
