Abstract

PURPOSE:To execute automatic coupling and separating by coupling plural male joints connecting to hose members to a holding frame having a slide block and coupling the same to plural female joints provided to an operating machine so that the slide block operates in a self-aligning manner even if the joints shift positionally from each other. CONSTITUTION:A male block body A provided with the plural male joints 2 connected to the hose members and the holding frame C which moves forward and backward the block body A are made of separate bodies. The block body A is connected to the female block body B which is attached to the operating machine and is provided with the plural female joints 52 and thereafter the frame C is separated from the body A and is retreated. There is therefore no need for increasing the height of the frame C and the frame is made smaller in size and lighter in weight, by which the installation space is narrowed. Both blocks A and B can be coupled smoothly and without fluid leakage. The automatic coupling and separating of the two blocks are thus made possible. The slide block 26 which is vertically and laterally movable is provided further to the frame C so that the coupling operation is made self-aligning and smooth even if both members are positionally shifted from each other.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is applicable to rolling mills for steel manufacturing and large industrial machines, when rearranging or repairing rolling rolls or work units.
The present invention relates to a method and device for connecting piping joints that can automatically and safely and reliably connect and separate a plurality of piping joints attached to the fuselage and a plurality of piping joints connected to the bong/side.

(Prior art) For example, in rolling equipment for steel manufacturing, in order to ensure smooth operation of the rolling rolls during operation, it is necessary to lubricate the bearings of the rolls. A refueling hose is connected to the bearing part so that the required amount of oil is always pumped in. When the roll is to be inspected or repaired regularly, the roll is pulled out from the housing, but before the roll is pulled out, the refueling hose is connected to the bearing part. Previously, each pipe joint had to be manually operated to remove the hose, which was not only a bad working environment but also extremely inefficient, so recently the method shown in Figure 9 A has been adopted. As shown in the figure, a female block body having a plurality of female joints f provided above and below and a guide hole g formed in the center is attached to the surface of the bearing box R1 of the rolling roll R (only one is shown for convenience). A holding frame H'4 that can be advanced and retracted by a hydraulic cylinder a is arranged at the opposite position.
The housing is connected to the tank and has a male block body B1 having ΦJ on the top and bottom and a guide pin p'lt in the center. A piping connection device is used which is elastically supported by the upper and lower springs S as well as a slidable fitting between the body and the rolling roll R to the holding frame H' by a hydraulic cylinder a.
The guide pin p of the male block body B□ is fitted into the guide hole g of the female block body B2, and simultaneously connected to the plurality of male joints MY and the plurality of female joints f, and the holding frame H % retraction allows multiple fittings to be separated simultaneously.

1. By the way, when repairing or inspecting rolling rolls, generally, as shown in Figure 9, the pass line 11 (steel plate passing line) is lowered from the steel plate passing line position to the reassembly position lt, and the piping is separated and connected. At the same time, the rolling roll q-R is pulled out and installed, and at the end of the installation, the joints f and m are connected 1M, and then the rolling roll IIL is raised again at the pass line J, !. , the male block body B1 equipped with a male joint m needs to be lifted up and down in relation to the elevation of the rolling roll R (approximately 100 to 150 mm), and the scale of the holding frame H supporting this is large (
Therefore, it is difficult to set up in a limited space, and the installation location must be modified in order to set it.In addition to the inconvenience caused, scales etc. scattered during operation may be damaged by the bearings on both sides of the male block B□. It is caught between the sliding part of the piece i and the holding frame H, and the vertical movement of the bearing piece i 'lk is inhibited.

When reconnecting the male joint f□1m, there is a risk of straining or not being able to form the knot 8.

Therefore, this invention has developed a joint that can be easily and safely removed automatically from the female and male joints without creating a large pot with a holding frame (and without being affected by scales etc. scattered during operation). The connection method and connection device are provided and the purpose and purpose of the connection are provided.

(Means for solving the problem λ) Based on the above-mentioned concept, the present invention first provides a cylinder to a male hose member connected to a hose member and assembled with a plurality of male joints. A holding frame that moves forward and backward is connected by a member, and the holding frame and male block body are moved forward and upward by an upper cylinder member.

In this state, when the holding frame C is moved back by operating the main cylinder 20, the locking pin 3 to the male block body 3 starts to separate from the furnace long body 60 because it is stuck thereto.

At that time, a conical recess Pf is formed in the tip 113b of the lock pin 3.
r70 a The Φ inner three gear 0 moves forward as the lock pin 3 moves due to the action of the coil spring 69, and its tip surface pushes up the lower end of the steel ball 68, causing its outer end to move vertically. The outer sleeve 66 protrudes slightly from the hole 60d, and is engaged with the P3 side taper 66c of the outer sleeve 66, which has been advanced by the restoring force of the coil spring 65 when the male slide ring 6 is separated, as shown in FIG. Hold.

In addition, due to the retreat of the holding frame C and the male block body A, the male
+2 and the female joint 52 will be separated, but in that case, the kubobet valves 2j and 52g, which are assembled in the male body 2a and the female body 52a, will be separated by the coil springs 21 and 52h, respectively. The elastic sealing material embedded in the head surface of the male side moves forward while contacting each other, and the male side small diameter @zbP'
3. The outer surface of the small diameter portion 2b of the male body 2a is in close contact with the elastic sealing material 5zjvc provided at the tip of the large diameter hole 52C of the female body 52a along with the pressure contact 0 on the tapered surface of 3@ or in the tapered direction 52d at the center of the female side. Since the FF3s fluid is not leaked to the outside during the separation operation.

Then, the salt block A is separated from the acid block B while being integrated with the holding frame C as shown in Fig. 6.
To make rearranging work of rolling rolls easier.

In addition, in the above example, the rolling roll for cracked iron was explained in the seventh usage state, but the uninvented device requires lubricating the bearing part during work not limited to this, and the actuator part unit It can also be applied to other industrial machines that can be recombined as follows.

ty: The number of male joints and female joints to be assembled to the block body can be appropriately selected from two or more.

(Effects of the Invention) As described in detail above, in this invention, the salt block body connected to the hose member and equipped with a plurality of male joints and the holding frame for advancing and retracting the salt block body are separate bodies, and the salt block body is connected to a plurality of male joints. The male joint of the T11 industry is attached to the acid block body with multiple female joints, so it can be separated from and retracted from each block body. It can be hung on objects, the installation space is reduced, and it is not affected by scale etc. Connect multiple male and female fittings without fear of fluid leakage.
Meeting.

Separation? It is extremely safe and efficient as it can be done automatically at the same time, and the holding frame is equipped with a slide block that can move up and down and left and right to connect the salt block body and the female block body. As planned, even if there is some misalignment between the positions of one member, the M attachment operation can be performed smoothly and aligned.
