Conventionally, the case of a stationary lubrication system and the measuring unit of a suspended lubrication system have been formed by a frame consisting of columns, beams, etc., and within the frame there are a vibration source consisting of a lubrication pump, a motor, a flow meter, etc., a counter, A refueling detector such as a transmitter is fixedly attached to a support, a beam, or a shelf board, and the output shaft of the flow meter and the human power shaft of the refueling amount detector are fixedly connected so that rotation is transmitted. It had become.

For this reason, especially in a suspended refueling system that uses a small totalizing counter and a transmitter as the refueling amount detector, the weight of the refueling amount detector is small, so vibrations of the motor and pump may be transmitted to the column, the flow meter, and even the flow meter. It is transmitted to the oil supply amount detector via the output shaft of the meter, etc., which may cause the number on the counter to be incorrect, cause the transmitter to malfunction, or shorten the life of mechanical parts. was occurring.

The present invention was devised to eliminate the disadvantages caused by such conventional techniques, and is designed to prevent vibrations from the oil pump, motor, flow meter, etc. from being transmitted to oil supply amount detectors such as counters and transmitters. The object of the present invention is to provide a refueling device that achieves the above-mentioned characteristics.

In order to achieve the above object, the feature of the configuration adopted by the present invention is that the oil supply amount detector is elastically attached to the frame body through an elastic body so as to isolate the oil supply amount detector from the vibration source. The output shaft of the flow meter and the input shaft of the oil supply amount detector are connected to each other through a connecting member having a slight play so that rotation can be transmitted thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the oil supply system of the present invention applied to a metering unit of a suspended oil supply system will be described below in detail with reference to the drawings.

Reference numeral 1 indicates a metering unit of a suspended refueling system, and the unit 1 is installed at a location that does not interfere with the movement of automobiles, such as in an office building at a refueling station.

This unit 1 is roughly composed of a frame 2, a vibration source including a pump 3, a motor 4, a flow meter 5, etc. housed in the frame 2, and a refueling amount detector 6 such as a counter and a transmitter. has been done.

The frame body 2 includes four pillars 7, 7, . 8... (4 or 8 locations on the top and bottom) in a rectangular parallelepiped shape.

A shelf board 9 is horizontally suspended in the middle part of this frame body 2, and this shelf board 9
A pump 3 is fixed on top.

The inlet of the pump 3 is connected to a pipe 10 leading to an underground tank, and the outlet of the pump 3 is connected to an inlet of a flow meter 5 mounted and fixed on the pump 3.

A pipe 11 is connected to the outlet of the flow meter 5, and the pipe 1
1 is guided to a high place such as a ceiling or a canopy, and the pipe 11
A refueling hose is suspended from the tip.

On the other hand, a motor 4 is fixed to the lower side of the frame 2, and the bobbin of the motor 4 and the pulley of the pump 3 are connected by a belt.

Next, the mounting structure of the oil supply amount detector 6, which is the main part of the present invention, will be explained.

First, on the upper part of the frame 2, beams 12.12 having a rectangular cross section are horizontally suspended in the direction perpendicular to the plane of the paper in FIG. Diameter hole 13.1
3... are drilled.

On the other hand, a refueling amount detector 6 having a built-in counter and a transmitter is mounted and fixed on a mounting plate 14, and the beam 1 is also mounted on the mounting plate 14.
Holes 15, 15, . . . are provided at positions corresponding to the holes 13, 13, . . . in 2.12.

A spring 16.16 is stretched between the beam 12.12 and the mounting plate 14 as an elastic body, and the hole 13.15 has a large diameter in the middle and a male screw at both ends. A shaft 17 with a 18.

Furthermore, a rubber sheet 19 is inserted between the beam 12 and the lower nut 18 as an elastic body by being pressed against the metal fitting 20 in order to further improve the vibration-proofing effect.

Although this embodiment has been described as using the spring 16 and the rubber sheet 19 as the elastic bodies, the mounting plate 1
A thick rubber sheet may be used between 4 and the beam 12,
Further, a combination of a hydraulic shock absorber and a spring may be used.

Next, the coupling relationship between the oil supply amount detector 6 and the flowmeter 5 will be explained. The output shaft 5A of the flowmeter 5 and the input shaft 6 of the detector 6
A means that even if the flowmeter 5 and the detector 6 vibrate in the vertical and horizontal directions, the rotation (measurement signal) from the flowmeter 5 is transmitted to the detector 6 through the output shaft 5A and the human power shaft 6A of the detector 6. The counter and transmitter are connected using a connecting member 21 shown in FIG. 3 so as to be transmitted to the transmitter.

The connecting member 21 includes a hollow cylindrical main body 21 A and the main body 21
The pins 21B and 21B are provided perpendicularly to each other at both ends of the shaft A, and the grooves 5B and 6B provided in the shafts 5A and 6A are inserted into the pins 21B and 21B to connect the output shaft 5A and the human power shaft 6.
A is connected.

In this case, the inner diameter of the main body 21A is made slightly larger than that of the shafts 5A and 6A, and the width of the grooves 5B and 6B is made slightly wider than that of the pin 21B, so that the output shaft 5A and the input shaft 6A can move easily with a slight play. has been done.

Further, the tips of the shafts 5A and 6A may be formed into spherical shapes.

In the oil supply device configured as described above, when the motor 4 is started, the pump 3 is rotated, and the oil is sent to the oil supply hose via the piping 10, the pump 3, the flow meter 5, and the piping 11, and oil is supplied. Ru.

In addition, a signal from the flowmeter 5 is sent to a detector 6, and an electric signal is sent from the transmitter of the detector 6 to a display placed at a position that is easily visible from the refueling point, so that the amount of refueling is displayed and the detector The counter 6 integrates and displays the amount of refueling.

At this time, the pump 3, motor 4, and flow meter 5 generate vibrations, but the oil supply amount detector 6 is connected to the support 7 and the beam 12 by an elastic body (
Since the detector 6 is supported via a spring 16 and a rubber sheet 19), the detector 6 does not vibrate much, and the amount of oil supplied and the signal from the transmitter are accurately transmitted.

Further, the output shaft 5A of the flowmeter 5 also vibrates slightly, and this vibration is also transmitted to the input shaft 6A, but the output shaft 5A and the input shaft 6A are connected by a connecting member 21 with a slight play. Therefore, vibrations are not directly transmitted to the joint between the input shaft 6A and the detector 6, and vibrations transmitted to the human power shaft 6A are also attenuated by the elastic body.

In addition, although this embodiment has described the metering unit of a suspended type oil supply apparatus as the oil supply apparatus of the present invention, it goes without saying that it may be used for a stationary type oil supply apparatus.

In addition, when a rubber gasket or the like is interposed between the hole 13 of the beam 12 and the shaft 17 to regulate the horizontal position of the mounting plate 14, when connecting the output shaft 5A and the input shaft 6A, the connecting member 21 and the shaft 5A , 6A does not need to have more play than necessary.

Since the oil supply device according to the present invention is as described above, it achieves the following effects.

■ The oil supply amount detector such as a counter and transmitter is supported via an elastic body on the pillars, beams, shelf boards, etc. of the frame, so it is free from vibrations generated by vibration sources such as motors, pumps, flow meters, etc. is attenuated, so that the counter is easy to read, false triggering of the transmitter can be prevented, and long-term use of the mechanical parts is possible.

■ The output shaft of the flowmeter and the input shaft of the refueling amount detector are connected with a slight play so that rotation is transmitted even if the output shaft is displaced, so even if the entire detector vibrates, the flowmeter will not work. Rotation is transmitted from the flowmeter to the detector, and even if the output shaft vibrates via the flowmeter, the input shaft does not vibrate directly, and no load is applied to the joint between the human power shaft and the detector.

Furthermore, since the vibration transmitted from the output shaft is also attenuated by the elastic body, the vibration of the detector can be suppressed to a lower level.
