Abstract

(57) [Summary] [Purpose] To balance the extension pipe attached to the swing pipe,
This was secured by piping that transports ready-mixed concrete. [Structure] In a portable concrete distributor in which an extension pipe 6 equipped with a tip hose 7 is attached to a swirl pipe 3 connected to a ready-mixed concrete introduction pipe 1, the swirl pipe 3 includes:
A U extending in the opposite direction and having approximately the same length as the extension pipe 6
The present invention is characterized in that a shape-shaped balance tube 10 is attached, and the extension tube 6 is attached to the balance tube 10.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a portable concrete distributor for concrete pouring. Ru.

0002

[Conventional technology]

In this type of portable concrete distributor, it is connected to the ready-mixed concrete introduction pipe. An extension tube with a hose at the end is attached to the swivel tube. Figure 2 shows an example of a conventional portable concrete distributor. A swing pipe 3 connected to a condenser introduction pipe 1 via a siebel joint 2 is connected to a bearing 5 on a pedestal 4. An extension pipe 6 is attached to this swing pipe 3, and a tip hose 7 is attached to the extension pipe 6. It is designed to be attached via a seal joint 2 and a vent pipe 8.

0003

[Problem that the idea aims to solve]

The conventional extension pipe piping described above is designed to withstand the overturning moment during pouring of ready-mixed concrete. This means that the center of the upper device, which is heavier and has no choice but to make the stand 4 larger, will require a large There is a drawback that it becomes difficult because it is a mount, so it is difficult to extend the tip hose 7 rearward. It is also possible to make the frame 4 smaller by placing a balance weight 9 on top. However, in this case, transporting, installing, and removing the weights 9 requires time and effort.

0004 The present invention was developed to deal with such problems, and the balance Intended for piping of broken extension pipes.

[0005]

[Means to solve the problem]

The configuration of the present invention for achieving the above purpose will be explained using FIG. 1 corresponding to an embodiment. To clarify, the present invention is an extension pipe having a tip hose 7 on a turning pipe 3 connected to a ready-mixed concrete introduction pipe 1. In the portable concrete distributor to which 6 is attached, the above-mentioned A U-shaped balun that extends in the opposite direction and has approximately the same length as the extension tube 6 is attached to the turning tube 3. A balance tube 10 is attached to the balance tube 10, and the extension tube 6 is attached to the balance tube 10. Ru.

[0006]

[Effect]

In contrast, the present invention uses the above-mentioned means to separate the extension pipe and the end hose at its tip. During pouring due to the weight of the balance pipe extending to the opposite side and the fresh concrete packed inside it. It maintains balance, and the frame can be made extremely small and lightweight, making it easier to transport by hand.

[0007]

【Example】

An embodiment of the present invention will be described below based on FIG. The same parts as those in the conventional example shown in FIG. In the present invention, the turning tube 3 has approximately the same length as the extension tube 6 and extends in the opposite direction. Attach an extending U-shaped balance tube 10, and attach an extension tube 6 to the balance tube 10. It was to so.

[0008] Thus, what is the weight of the extension pipe 6 and the tip hose 7, and the weight of the ready-mixed concrete clogged therein? The rotating pipe 3 is balanced by the weight of the balance pipe 10 and the weight of the fresh concrete packed in it. Even if the supporting frame 4 is small, it may be affected by the weight of the tip hose 7 and the pulsation of the fresh concrete flow. Can withstand reaction forces and vibrations.

[0009]

[Effect of the idea]

In this way, according to the present invention, the swing tube supported by the frame is equipped with a hose at the end. Attach a U-shaped balance tube that extends in the opposite direction and has approximately the same length as the extension tube. , an extension tube with a tip hose is attached to the balance tube, so the tip hose is attached to the balance tube. The extension tube with a By making the frame that supports the pipe smaller, the rotating pipe can move in a well-balanced manner, making it easier to place ready-mixed concrete. By changing the length of the extension tube, you can freely change the possible pouring range. It has the effect of
