Description

[Detailed Description of the Invention] This invention relates to a hydraulically driven hose reel for a tank car, and its purpose is to make the whole reel compact so that it can be easily mounted on a chassis.

Generally, in small tank cars that deliver, for example, kerosene, light oil, heavy oil, etc. to homes, etc., a powered hose reel is mounted on the chassis in order to improve work efficiency. In this case, conventional hose reels include those in which the motor is attached directly to the drum shaft outside the drum, or as shown in FIG. There were some that connected the two via a power transmission mechanism e such as a belt or chain. However, the former, that is, one in which the motor is directly connected to the outside of the drum, requires a large space between the shovel cab and the tank, is not convenient for mounting, and is not very practical. The latter, that is, the one using the power transmission mechanism e, does not have any major disadvantages in terms of mounting, but it has the disadvantage that work such as piping is difficult and additional space is required.

This idea was made in view of the above problems,
By installing the hydraulic motor, which is the drive source for the hose reel, inside the drum so as to be directly connected to the rotation axis of the drum, the hose reel can be made more compact and can be easily installed on the chassis, while also making it easier to install piping, etc. An object of the present invention is to provide a hydraulically driven hose reel for a tank car, which is characterized by being easy to work with.

This invention will be explained below based on FIGS. 1 to 3.

1 and 2 respectively show a front view and a central vertical cross-sectional view of the hose reel of this invention. In the figures, 1 is a drum, 2 is a drum stay that supports this drum 1, and When the drum 1 is rotatably supported within the drum stay 2, which is formed into a U-shape, as shown in FIG. A casing rotary hydraulic motor 3 with a rotary casing 3c fitted therein is installed in the drum 1 in the same way as the rotating shaft of the drum 1, and a stator 3a is attached to one support piece 2a of the drum stay 2. The end of the rotary casing 3c on the stator attachment side is attached to one end of the drum 1 with bolts 4, while the cylinder portion 3d protruding along the rotation axis of the rotary casing 3c has a , a rotary joint 6 is connected using a key 5, and the drum 1 is attached to the other end of the drum 1 via this rotary joint 6. In this case, the rotation joint 6 includes a fixed shaft 6b having an oil supply passage 6a horizontally suspended on the other support piece 2b of the drum stay 2, and a bearing cylinder 6 on the distal end side of the fixed shaft 6b.
The rotary cylinder part 6d is rotatably attached via the rotary casing 3c, one end of the rotary cylinder part 6d is connected to the rotary casing 3c, and the other end is attached to the other end of the drum 1 with a bolt 4. It is being In the illustrated example, the rotating casing 3c and the rotating cylinder portion 6
Although the motor 3 and the rotary joint 6 are directly connected to each other, a spacer or the like may be interposed between the motor 3 and the rotation joint 6 to connect the motor 3 and the rotation joint 6.

A passage 6e that communicates with the oil supply passage 6a is bored in the rotary cylinder portion 6d of the rotation joint 6, and piping equipment that communicates with this passage 6e is attached. Further, an attachment flange 6f is formed at the externally protruding end of the fixed shaft 6b, and the tank side piping is connected using this flange 6f.

The hose reel of this invention configured as described above has a casing rotary hydraulic motor installed in the drum coaxially with the rotating shaft of the drum, and also rotates the rotating part of the motor, that is, the rotating casing and the drum. Since they are connected via a joint, they can be made more compact than conventional hose reels of this type. It has excellent effects such as being able to easily mount it on the chassis and simplifying piping work by reducing the number of piping, etc., and its utility value is remarkable.
