Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic connection of fluid and electrical wiring between a moving object and a device held in place;
The automatic opening device is characterized in that the connection does not come off even if the moving object side is moved considerably after connection.

A moving object means any moving object that is equipped with a pressurized fluid device or an electrical device, including a vehicle, and a device that is held in a fixed position (hereinafter referred to as a fixed device) is a device that is fixed and held in a fixed position on the ground. , for example, means a supply device for pressurized fluid, electricity, etc. In order to stop the moving object next to the stationary device and supply pressurized fluid and electricity, various means have been devised to automatically connect the joints of piping and wiring between the two devices. For example, the applicant's patent application filed in 1973
-153355 (Japanese Unexamined Patent Publication No. 56-75261) was invented as the first
As shown in figure a, the left stationary device side 101
The moving object side 102 moves in a direction perpendicular to the connection axis and stops at a position where it can be connected, and the cylinder 103 on the stationary device side operates to connect the piping wiring joint 1.
04 and automatically connects it to the joint 104a on the moving object side. 105,1 in the figure
05a is a guide vane for connection guidance of the same shape, 10
6,106a is a universal bearing of the joint shaft, 107,1
07a is a spring that is attached to the outer periphery of the joint shaft and provides pressure contact force when connecting both joints, and by these actions, even if the axes of both joints are slightly misaligned before connection, they are automatically aligned and aligned. Connect as shown in Figure 1b. However, if the moving object moves in a direction perpendicular to the connection axis of the stationary device after connection, if the amount of movement is small, the joint will be connected by compression or expansion of the compressed springs 107, 107a, as shown in FIG. 2a. is not released, but if the amount of movement increases and the spring is fully extended, the second
As shown in Figure b, the connecting surfaces are separated and released.

Another conventional example is disclosed in Japanese Patent Application Laid-Open No. 116707/1983. This conventional device makes contact between the power receiving coupler (first joint) provided on the pig iron mixer (moving object) and the power feeding coupler (second joint) provided on the ground side at the stop position of the pig iron mixer (moving object). In a power source coupling device for connecting surfaces, the power receiving coupler (first joint) has its contact surface facing upward, and the power supply coupler (second joint)
has its contact surface facing downward, is installed on the ground, has a flexible cable, and connects the power supply coupler (second joint) above the power receiving coupler (first joint) by means of the cable. Lifting means that lifts and lowers the rope and releases the suspended state of the cable when the two contact surfaces are connected;
The power supply coupler (second joint) is connected to the power receiving coupler (first joint) in response to the lowering operation of the power supply coupler (second joint) by the elevating means.
(a joint) and means for guiding the vehicle to be mounted on the joint.

According to this conventional device, the power supply coupler (second
When the elevating means is lowered after the power receiving coupler (first joint) is positioned above the power receiving coupler (first joint), the power feeding coupler (second joint) is lowered by its own weight, and at this time, the guide means Both couplers (both joints) are connected by the action of the power supply coupler (second joint), and then the flexible cable is hung down so as to be relaxed, and the suspension of the power supply coupler (second joint) is released.

Therefore, even if the pig iron mixer (moving object) simply moves horizontally after the couplers (both joints) are connected, the connection can be maintained because the suspension of the cables is loosened.

However, the road surface or rail laying surface before and after the stopping position of a moving object is not necessarily horizontal, and in reality is often a sloped surface. When the two joints are connected, the moving object itself on the inclined surface is also tilted, and the connection of the above conventional device depends on the weight (including weight) of the power supply coupler (second joint). In addition, vibrations and tilting caused by back-and-forth movement from the connecting position cause looseness in the connecting portion, resulting in poor contact between the wiring contact portions between the two joints and fluid leakage from the piping contact portions. Therefore, the present invention addresses the above-mentioned problems by connecting the second joint on the stationary device side to the first joint on the moving object side. Even in such a case, the two joints can be kept in perfect contact with each other.
