[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation device for a water faucet with excellent earthquake resistance, which is installed at a branch port formed in a fluid pipe such as a water pipe.

[0002]

2. Description of the Related Art As an attachment device of this type of water faucet, there is a prior application (Japanese Patent Application No. 6-117084) to which the present applicant relates. In this attachment device, after attaching the lower end portion of the inner nut 51 to the saddle 133 as described in the specification and drawings, the auxiliary handle 146 is attached to the handle attachment portion 48 of the nut holder member 42 and rotated (Fig. 8 and 9), the outer nut 50 whose upper end is fixed to the nut holder member 42 is a saddle 133.
Due to the screwing relationship with the inner nut 51 whose lower end is fixed to
Along with it (Fig. 1 → Fig. 9). At this time, the upper end is fixed to the nut holder member 42, the guide press-fitting pipe 53 located inside the outer nut 50 also descends (FIG. 9), and the units attached to the lower end of the pipe via the nut 56. (Lower body 58, mounting nut 61, packing 63, tubular metal fitting 14
0, rubber ring 143), rubber ring 143, tubular fitting 140, water pipe 13
Pressed into the branch port 137 that was drilled in 0 (Fig. 9), and the mounting nut 61
The lower surface of the rubber ring 143 presses the flange portion of the rubber ring 143.

Therefore, (1) it takes a long time to descend the units. (2) When both the inner and outer nuts 50 and 51 are in a threaded relationship and the threaded pitch is increased, the device is more prone to rattling due to the thread tolerance, and a perforated branch port is formed.
The rubber ring 143 or the like may be pressed into the 135, which may cause trouble. (3) Since there is no mechanism for knowing the degree to which the flange portion of the rubber ring 143 is pressed against the outer peripheral surface of the pipe by the mounting nut 61, the pressing degree may vary depending on the person who operates it, which may impair the watertightness. There is. There are many problems.

In the vertical movement mechanism of the main shaft 8, a rotatable auxiliary shaft 66, which projects from the main body 38 and has a handle wheel 125 at the end, is erected on the bottom plate 65 inside the main body 38. One end of the expanding bar member 71 is screwed into the intermediate portion of the sub shaft 66 via a fulcrum nut 72 serving as a fulcrum, and the other end of the bar member is located on the opposite side of the sub shaft with the main shaft 8 in between. Then, the main shaft 8 is moved up and down by the crank portion at the end of the crank shaft 102 rotated by the motor, and the main shaft 8 is moved up and down via the joint 8b fixed to the main shaft 8 in the middle of the bar member 71 (Fig. 1). The rotation of the main shaft 8 has a link plate 84 whose one end is connected to the crank portion, and the other end of the plate is connected to the ratchet mechanism to rotate the main shaft 8 in small steps by the movement of the plate 84. (Figs. 5 and 6). The rotation timing of the sub shaft 66 for pulling up the main shaft 8 is regulated by the lever 115 which is interlocked with the rotation of the main shaft 8 (FIGS. 1 and 7).

Therefore, the main shaft 8 is rotated by the rotation of the motor.
Moves up and down a certain distance and rotates in a certain direction,
There is also a problem that unless the rotation of the auxiliary shaft 66 is relaxed manually and the auxiliary shaft 66 is rotated to raise the fulcrum nut 72, it is not possible to enter the next expanding operation with the main spindle slightly raised. Have That is, (1) After the diameter of the end of the tubular metal fitting 140 is increased by one revolution of the hook member 13, the hook member 13 is slightly raised, that is, when the main shaft 8 is slightly raised to move to the next diameter expansion, the auxiliary shaft is manually operated. Requires 66 rotation operations. (2) Manpower is required until the expansion is completed. (3) When manually rotating the auxiliary shaft 66, the timing for rotating the auxiliary shaft 66 is limited to a release point for restricting the rotation of the auxiliary shaft 66 due to the rotation of the main shaft 8. If this point is released, the main shaft 8 cannot be pulled up. It will be a waiting time and prolong the expansion work time. Conversely, it is necessary to always pay attention to this point. (4) Secondary shaft 66 for pulling up main shaft 8
Since it is carried out manually via the, the end point of the diameter expansion is unknown.

At this time, the lower end of the tubular metal fitting 65 is partially fitted inside the upper portion of the rubber ring 67.

On the other hand, as shown in FIG. 1, a perforator 37 is vertically attached to the fluid pipe 36 via a chain 140 and a bolt nut 141, and the fluid pipe 36 is attached to a base 37 of the perforator, not shown. A branch hole 142 is formed by punching with a tool. Branch 1
After forming 42, the punching jig is pulled up to the position above the valve 143 of the punching machine 37, the valve is closed, and the punching jig is removed leaving the punching machine 37. After removing the drilling jig, drilling machine
The gasket 39 is arranged on the upper end surface of the 37, and the lower part of the diameter expansion jig 2 is put in the upper part of the punching machine 37 and the case 70 and the main body outer cylinder.
42 is fixed, and the fixing downward cap nut 38 provided at the lower portion of the fixed column 40 is screwed with a male screw formed on the outer periphery of the upper portion of the base 37 of the punching machine by a jig (not shown). As a result, the diameter-expanding jig 2 and the diameter-expanding machine 3 are attached to the upper part of the base 37 of the punching machine.

Next, after the valve 143 of the base 37 of the punching machine is opened, the handle 44 is rotated to lower the outer cylinder 42 of the main body with respect to the fixed support column 40 in FIG. Then, the rubber ring 67 first enters the branch port 142 of the fluid pipe 36, and when it is further lowered, the tubular metal fitting 65 is press-fit into the rubber ring 67. If it is still lowered, the upper flange 67a of the rubber ring 67 will
It is pressed by the underside of 62 (Figs. 1, 8). This pressing amount is read by the scale 57 and the pointer 58 of the cover 56 which are set in advance. In this way, the amount of pressing of the rubber ring 67 can be made constant.

Then, the ratchet pawl 107 and the ratchet gear 105 are disengaged with the pawl releasing jig 125, and the main shaft handle 116 is released.
Is rotated to lower the spindle 8 to the lower limit, the knob 120 is pushed down, the movable shaft 10 in the spindle 8 is lowered, and the hook member 13 is projected from the window 7a of the hook member accommodating portion 7 (FIG. 2 → FIG. 3). After the hook member 13 is projected, the hook member 13 is fixed by screwing and tightening the knob 120 onto the upper portion of the main shaft 8. Then, the handle 116 is turned to pull up the main shaft 8 until the lower end of the tubular metal piece 65 comes into contact with the molding surface 12 of the hook member 13, and the pawl opening jig 125 is pulled up to engage the ratchet pawl 107 and the ratchet gear 105.

The disc spring 110 is housed in the recess in a state in which 110 is pressed to apply a compressive urging force equal to or larger than the maximum load necessary for expanding the diameter of the tubular metal piece 65. The gauge 123 hanging from the other end of the gauge arm 122 is provided with a step portion 163. A fixed column 165 is vertically provided on the upper surface of the intermediate base 91. A limit switch 166 is attached to the fixed column 165, and a roller 168 that rolls on the surface of the gauge 123 is provided at the tip of an operating piece 167 of the switch. A limit switch 111 and an adjusting bolt 112 are provided on the female screw member 72 for the main shaft and the spring case 73 as in the above embodiment. The other structure is almost the same as that of the above-mentioned embodiment.

In the case of the above-described embodiment (FIGS. 1 to 23), the disc spring due to the increase of the load caused by the expansion of the diameter.
Limit switch 111 that captures the amount of displacement in the compression direction of 110
In the case of this embodiment,
The amount of diameter expansion is set by the upward movement distance of the main shaft 8. That is, as the diameter of the tubular fitting 65 increases, the main shaft 8 moves up and down while repeating vertical movements, and the handle 11
The gauge 123 attached to 6 also rises, the roller 168 of the limit switch 166 attached to the fixed support 165 rolls on the surface of the gauge 123, the operating piece 167 moves at the step 163, and the limit switch 166 is turned off and the motor 88 stops. As described above, according to the configuration of this embodiment, since the amount of diameter expansion is detected by the amount of movement of the main shaft 8 and the diameter expansion work is completed, there is some variation in the thickness and hardness of the tubular metal fitting 65 used. Even if there is a change (even if the load changes during molding), it is possible to obtain a predetermined amount of diameter expansion with high accuracy.

Since the present invention is constructed as described above, the units can be lowered quickly and accurately. Moreover, rattling does not occur in the device. Further, since the degree of the pressed amount of the flange portion of the rubber ring can be known by the display mechanism, it is possible to prevent the operator from having the different degree. Further, even when the diameter of the tubular metal fitting is being expanded, no human operation is required, and the diameter expansion work can be automatically terminated, and automatic operation can be performed. Also, when the load applied to the hook member reaches the set value when the diameter of the tubular metal fitting is expanded, or when the upward moving main spindle reaches the predetermined upper moving position, it is detected and the driving member stops driving from the control member. Since the signal is output, even if the same device is used, it is possible to respond appropriately even if the pipe thickness of the fluid pipe changes, and it is possible to accurately expand the diameter of the fluid pipe.
