Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete pump vehicle equipped with a concrete transfer boom device in which the boom device along which concrete transfer piping is installed can be removed from the vehicle body.

Generally, a concrete pump truck with a boom is used when pouring at a high place using a boom device, and a concrete distributor device is used when pouring the floor of a building by attaching it to a pillar or crane post of a building. Ta.

However, since there are two types, when one is used, the other is often not used.
The operating rate of each of these devices is low, and in the case of the concrete distributor device, it is difficult to transport the device itself, requiring a large amount of man-hours and a transportation vehicle.

The present invention solves the above-mentioned drawbacks by fixing a lower mounting table to the upper end of the swivel base, and attaching the upper mounting table provided at the lower end of the mounting post of the boom device to the upper surface of the lower mounting table using a mounting bracket. Furthermore, the concrete transfer pipe along the boom device is passed through the swivel base and the upper and lower mounting tables, and this concrete transfer pipe and the concrete transfer pipe from the concrete pump mounted on the vehicle body are connected to the support stand. When the boom device is attached to a concrete pump truck, it can be used as a concrete pump boom truck, and when it is removed, it can be attached to a pillar or crane post of a building and used as a concrete pump. It is designed to be used as a triviewer device to improve the operating rate.

To explain the embodiment below with reference to the drawings, the vehicle body 1
A swivel base 3 is mounted on the front part of the swivel base 3 via a support base 2 so as to be rotatable around a vertical axis, a mounting post 4 is provided on the swivel base 3, and a boom device 5 is mounted on the top of the mounting post 4. be.

A concrete pump 6 and a hopper 7 are mounted on the rear of the vehicle body 1.
Concrete transfer piping 8, such as a steel pipe, which communicates with the discharge port of the concrete pipe 8 is bent and passes through the inside of the support base 2 and the swivel base 3, is bent inside the mounting post 4, and is installed along the outside of the mounting post 4. After being further bent and passing through the shaft support 9, it is installed along the boom device 5.

Next, the main parts of the present invention will be explained. Reference numeral 10 denotes a horizontal circular lower mounting table fixed to the upper end of the swivel base 3. This lower mounting table 10 includes:
Four set pins 11, 11... are provided protrudingly.
Reference numeral 12 denotes a horizontal circular upper mounting table provided at the lower end of the mounting post 4, and this upper mounting table 12 has four holes 13, 13... drilled at positions corresponding to the four set pins 11, 11... be.

Reference numeral 14 denotes a semicircular mounting bracket with a U-shaped cross section that allows the upper mounting table 12 and the lower mounting table 10 to be attached and detached.
Tighten by 6.

17 is a rotating base 3, upper and lower mounting tables 12, 1
Concrete transfer pipe 8a that penetrates the inside of 0 and is installed along the boom device 5, and concrete transfer pipe 8 from the concrete pump 6 mounted on the vehicle body 1.
This is a coupling ring that removably connects b and b within the support base 2.

Reference numeral 18 denotes a rectangular attachment/detachment opening provided on the side surface of the support base 2, and the coupling 1 is inserted through this attachment/detachment opening 18.
Attach and detach 7. 25, 25 are hooks provided on the boom device 5.

Next, FIG. 5 shows an embodiment in which the removed boom device 5 is used as a concrete distributor device 19, and 20 is a drive device for driving the boom device.

Reference numeral 21 is a frame attached to a pillar 22 of the building. A swivel base 24 is rotatably mounted on the pedestal 21 via a support base 23. 8c is the concrete transfer pipe on the building side, coupling 17
Concrete transfer pipe 8 on the boom device 5 side
It is connected to a.

To explain the case where the present invention has the above-described configuration and uses the boom device 5 as a concrete distributor device 19 by removing the boom device 5 from a concrete pump vehicle, first, the concrete pump vehicle is driven to the site where concrete is to be poured. . Next, remove the coupling ring 17 from the attachment/detachment port 18, then remove the bolts 15, 15 and nuts 16, 16, and remove the mounting bracket 14.

Next, use a crane or the like to hook the boom device 5 to the hook 25,
25 is hung up and attached to a swivel base 24 rotatably mounted via a support base 23 on a pedestal 21 attached to a pillar 22 of a building.

Next, the concrete transfer pipe 8c on the building side and the concrete transfer pipe 8a on the boom device 5 side are connected by a coupling 17.

As described above, the boom device 5
The concrete distributor device 19 is capable of rotating and undulating the concrete, and can also place concrete by pumping the concrete.
It can be used as

Next, when removing the boom device 5 from the mount 21 and attaching it to the vehicle body 1, it is sufficient to perform the process in the reverse order.

As described above, according to the present invention, the lower mounting table is fixed to the upper end of the swivel base, and the upper mounting table provided at the lower end of the mounting post of the boom device can be attached to and detached from the upper surface of the lower mounting table using the mounting bracket. Then, the concrete transfer piping along the boom device is passed through the inside of the swivel table and the upper and lower mounting tables, and this concrete transfer piping and the concrete transfer piping from the concrete pump mounted on the vehicle body are coupled at the support stand. When the boom device is attached to a concrete pump truck by detachably connecting it with the holder, it can be used as a concrete pump boom truck, and when removed, it can be attached to a building pillar or crane post and used as a concrete distributor device. It can be used to improve the operating rate.
