Description

TECHNICAL FIELD The present invention relates to a pipe joining apparatus for joining pipes, particularly synthetic resin pipes.

Conventional technology For suspension cables in conventional cable-stayed bridges, many thin wires are used for FRP.
It is configured to be loaded into a pipe and lubricated to reduce mutual friction and prevent corrosion.

The problem to be solved by the invention is that, in such a case, the FRP pipe into which the wire is inserted has a predetermined unit length joined to form a long pipe. It is necessary to apply an adhesive to the inner and outer surfaces of the part, fit both ends, and dry. However, a device capable of efficiently performing such a series of work has not been proposed yet, and since many workers spend a long time, there is a problem that the work efficiency is extremely poor.

Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional technique and provide a pipe joining apparatus capable of joining pipes efficiently and reliably by a simple operation by a small number of workers. It is in.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a fixed pressing member for detachably mounting one pipe on one side of a base, and attaches and removes the other pipe on the other side. A movable pressing member that can be mounted is provided, and when the moving pressing member moves toward the fixed pressing member, when the opposite ends of both pipes are fitted, the drying cover that covers this fitting part is attached to and detached from the base. Provided as possible
A blower member for supplying hot air is provided in the drying cover, and a cover attached to the fixed pressing member side of the movable pressing member to cover and move the upper surface of the base is provided.

In the above-described pipe joining apparatus of the present invention, the pipes are mounted on the fixed / movable presser members, and the adhesive is applied to the inner and outer peripheral surfaces of the fitting ends of both pipes, and then the movable presser member is attached. The both ends are fitted by moving toward the fixed pressing member, the fitting cover is covered with a dry cover, and hot air is supplied into the cover by the blowing member, and the hot air causes the adhesive to solidify. When the pipes are joined, remove the drying cover and remove the pipes from both holding members.

It is pivotally supported by 14, and its upper part is composed of a bolt and a nut fitted in a groove 19 provided in the opening / closing part 17, and the opening / closing part 17 is loosened by loosening the nut and swinging the bolt so that it is located outside the groove 19.
Can be opened.

Rubber is attached to the inner surfaces of the recesses of the two pressing members 2 and 3.

On the lower surface of the moving portion 14 of the movable pressing member 3, the side wall of the base 1 is attached.
A bracket 21 is provided along the inside of 6, 6 ', and a rotary shaft 22 is supported by the bracket 21, and one end of the rotary shaft 22 is projected outward from a slot 23 horizontally provided in the front side wall 6. hand,
The base of the handle 24 is attached to its end. A gear 26 is attached to the rotary shaft 22, and this gear meshes with a rack 27 provided on the bottom of the base 1.

A base end of a first cover 28 that covers the upper surface of the base 1 is attached to the moving portion 14 of the movement holding member 3, and a roller 29 that rolls on the base 1 is attached to the front end of the first cover 28. A second cover 31 is connected to the front portion of the first cover 28 in a telescopic manner, and a roller 32 rolling on the base 1 is provided at the front end thereof.

A rubber pipe receiving roller 34 is provided adjacent to the fixed pressing member 2. The pipe receiving roller 34 has a hook shape and is rotatably supported between the side walls 6 and 6 '. 35
Is rotatably supported by a support shaft 37 provided on a bracket 36 attached to the front end of the rotary shaft 35. One end of the rotary shaft 35 protrudes outward from the front side wall 6, and the base end of the handle 38 is attached to the protruding end. There is.

Reference numeral 41 denotes an aluminum dry cover which is fitted to the joint portion of the pipes 50 and 51 between the pressing members 2 and 3 at the time of joining (Fig. 2), and is otherwise removed. A blower pipe 42 is connected to the upper portion, and a dryer for drying (not shown) is installed inside the blower pipe 42, or another blower air supply means (not shown) is connected to the blower pipe 42. And 43 is a handle for attachment and detachment.

When the pipes 45 and 46 are joined by the pipe joining device as described above, the movable pressing member 3 is set to the retracted position (left position in the drawing) shown in FIG.
Open 9,17 by unlocking the fixtures 10,18 and opening
The pipes 45 and 46 are placed in the concave portions of the fixed portion 5 and the moving portion 14 of the second and third portions, and the opening and closing portions 9 and 17 are closed and fixed by the fixing tools 10 and 18.

Then, an adhesive is applied to the inner peripheral surface of the female pipe 45 and the outer peripheral surface of the male pipe 46. At this time, the excess adhesive that drops off is received by paper (not shown), plates, etc. placed on the first and second covers 28, 31 to prevent the base 1 from being contaminated. Replace.

When the application of the adhesive is completed in this way, the handle 24 of the movable pressing member 3 is rotated clockwise as indicated by the arrow in FIG. 1, and this rotation causes the rotation shaft 22 and the gear 26 to rotate. When the gear 26 and the rack 27 mesh with each other, the moving portion 14 is moved toward the fixed pressing member 2. During this movement, the first and second covers 28, 31 also move, and the second cover 3

8 continues to move.

This movement stops the movement of the movable pressing member 3 at the joining position shown by the chain line in FIG. 1 and the solid line in FIG. 2 in which the tip of the pipe 46 is fitted into the tip opening of the pipe 45. The handle 24 is connected to an appropriate portion of the base 1 by a rubber band or the like (not shown) so as not to return.

When the fitting of the pipe 46 into the pipe 45 is completed in this manner, the drying cover 41 is placed on the base 1 so as to fit the fitting portion, and the drying cover 41 is inserted through the blower pipe 42.
Hot air is supplied to dry the adhesive. At this time, a gap is provided between the drying cover 41 and the base 1, and the hot air is discharged to the outside through this gap.

After drying is completed in this way, the opening and closing parts of both members 2 and 3
Open 9,17 and rotate the handle 38 clockwise as shown by the arrow in FIG.
34 is moved upward, and the joined pipes 45 and 46 are fixed to the fixing portion 5,
It is lifted from the recess of the moving part 14 and taken out of the device.
