Abstract

The present invention relates to a structure of a sponge ball catcher for a concrete pump truck, after the concrete is poured by connecting / mounting the sponge ball catcher (1) at the end of the sponge ball (S) and the transfer pipe (2a) from which the residue is discharged When cleaning the transfer pipe 1, it is possible to prevent the separation of the sponge ball (S), and to prevent the residue from being scattered when discharged to the outside.

Description

Structure of Sponge Ball Catcher for Concrete Pump Truck

The present invention relates to a sponge ball catcher for a concrete pump truck, and more particularly to a structure of a sponge ball catcher for a concrete pump truck that can prevent the sponge ball is discharged to the outside of the transport pipe when cleaning the concrete transport pipe.

In general, the concrete pump truck must remove the residues, such as concrete and gravel, from the concrete conveying pipe after placing concrete. Otherwise, cement is cultivated in the conveying pipe so that the conveying pipe cannot be used. Has become an important factor. Meanwhile, when cleaning the concrete conveying pipe, as shown in FIG. 1, vertically conveying pipes 2a can be removed by removing the elbow 2b by the weight of the residue, but the horizontally conveying pipe ( 2a, after inserting the sponge ball (S) in the pressure pipe 3, as shown in Figure 2, the medium between the flange (2d) of the feed pipe (2a) and the flange (3c) of the pressure pipe (3) After connecting the furnace feed pipe (2a) and the pressure pipe (3), the air inlet (3ab) of the pressure pipe (3) and the compressor is connected to the high-pressure air into the pressure pipe (3), the sponge ball ( S) is discharged to the outside along the transfer pipe (2a) to discharge the residue of the transfer pipe (2a).

However, the sponge ball (S) and the residues are injured by the sponge ball (S) that is released as it is released to the outside through the high-pressure air, as well as the residues scattered, as the working conditions of the worker There was a problem of getting worse.

The present invention has been devised to solve the above problems, and when cleaning the transport pipe after pouring concrete by connecting / mounting the sponge ball catcher at the end of the transport pipe (2a) that the sponge ball and the residue is discharged It is an object of the present invention to provide a structure of a sponge ball catcher for a concrete pump truck that can prevent the separation of the sponge ball.

2 is a detailed view of portion A of FIG. 1;

3 is a front view and a side view of the sponge ball catcher according to the present invention.

C --- concrete pump truck, B --- building,

S --- Sponge Ball,

1 --- ball catcher, 1a --- flange,

In order to achieve the above object, the present invention has a round bar having one end formed with a flange and communicating with the flange, a ring communicating with the round bar, and a plate mounted with '+' on the inner surface of the ring. Is done.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 3, the present invention has a round bar 1b having one end of the flange 1a and communicating with the flange 1a, and a ring 1c communicating with the round bar 1b. ) And a plate 1d attached to the inner surface of the ring 1c by a letter '+' to form a ball catcher 1. The ball catcher is formed at the distal end of the transfer pipe 2a of a concrete pump truck. Connected.

Here, when cleaning the transfer pipe (2a) after concrete placement, let's take a closer look at the connection of each pipe (1,2a, 3).

First, the sponge ball (S) and the outlet of the transfer pipe (2a) from which the residue is discharged is connected via the flange (1a). As shown in FIG. 2, the pressure ball 3 is inserted into the pressure ball 3 and the pressure pipe 3 is connected to the transfer pipe 2a to be cleaned.

Here, let's look at the operation relationship when cleaning the transfer pipe (2a) after concrete placement. The two handles 3aa and 3ba of the pressure pipe 3ab are positioned to prevent air from passing through, and then connected to a pipe of a compressor (not shown) through the air inlet 3ab. When the handle 3aa connected to the compressor is operated to allow air to flow through, the sponge ball S in the pressure pipe 3 passes through the first feed pipe 2a by air pressure and passes the last feed pipe 2a. It reaches the plate 1d of the ball catcher 1 and no longer moves forward. On the other hand, the compressor mounted on the vehicle pushes the sponge ball (S) by compressed air, and this sponge ball (S) is a pressure that the compressed air pushes out because water remains in the pipe and the diameter of the sponge is larger than the inside of the pipe. The residue inside the pipe is pushed outward so that the transfer pipe 2a is cleaned.

As described above, when the sponge ball catcher 1 is connected / mounted to the end of the sponge ball S and the transfer pipe 2a at which the residue is discharged, the sponge is cleaned in the transfer pipe 1 after the concrete is poured. The separation of the ball S can be prevented, and when the residue is discharged to the outside, it can be prevented from scattering, and thus the safety of the operator can be achieved.
