Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete pump vehicle equipped with a concrete transfer boom device in which an arm portion consisting of a base boom and a tip boom along which a concrete transfer pipe is installed can be removed from the vehicle body. It is something.

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, and consists of a base boom consisting of a first part whose base end is pivotally supported on a mounting post, and a second part whose distal end is pivotally supported on the tip of a tip boom. The tip of the section and the base of the second section can be attached and detached using mounting brackets, and a concrete transfer pipe on the tip side that passes through the shaft support of the base boom and the tip boom extends from the concrete pump and connects the mounting post and the base boom. When the arm part is attached to a concrete pump truck by connecting the base-side concrete transfer piping that penetrates through the shaft support of the base boom with a coupling, it can be used as a concrete pump boom truck, and when removed. The device is attached to a building pillar or crane post and used as a concrete distributor to improve operating efficiency.

The embodiment will be described below with reference to the drawings. A mounting post 3 is mounted on the front part of the vehicle body 1 via a swivel base 2 so as to be able to rotate around a vertical axis, and a base part is pivotably supported 4 on the upper part of the mounting post 3. a base boom 5; and a first tip boom 7 whose base is pivoted 6 at the tip of the base boom 5.
An arm portion 10 is attached to the tip of the first tip boom 7, and a second tip boom 9 whose base is pivotally supported 8 is attached. It is composed of 10.

A concrete pump 12 and a hopper 13 are mounted on the rear of the vehicle body 1, and a transfer pipe 1 such as a steel pipe is connected to the discharge port of the concrete pump 12.
4 is bent and passes through the inside of the swivel base 2, is placed along one side of the mounting post 3, and is further bent and passes through the shaft support 4 between the mounting post 3 and the base boom 5, and then
The transfer pipe 14 is installed along the other side of the base boom 5, and after passing through the bent shaft support 6, is installed along one side of the first boom 7, and the transfer pipe 14 is bent and After penetrating the 8th part of the support, the second
It is installed along the other side of the tip boom 9 and extends to the tip of the second tip boom 9.

Reference numeral 15 denotes a undulating cylinder installed between the mounting post 3 and a first portion 16, which will be described later.
The base boom 5 is raised and rotated by the raising and lowering operation of 5.

Next, the main parts of the present invention will be explained. The base boom 5 has a first part 16 whose base end is pivotally supported on the mounting post 3, and a tip end which is pivotally supported on the base of the first tip boom 7.
The second part 17 is made up of two parts. The tip of the first part 16 and the base of the second part 17 are connected to four pins 1.
8, 18... and nuts 19, 19... can be attached and detached.

14a extends from the concrete pump 12,
14b is a concrete transfer pipe on the base side that passes through the mounting post 3 and the shaft support 4 of the base boom 5, and 14b is a concrete transfer pipe on the front side that passes through the shaft support 6 of the base boom 5 and the first tip boom 7. The two are removably connected by a coupling ring 20.

Next, Figure 3 shows the concrete transfer pipe 14 on the tip side.
This figure shows an embodiment in which an arm portion 10 consisting of a base boom 5 and tip booms 7 and 9 along which b is used as a concrete distributor device 21.

Reference numeral 22 is a frame and is attached to a pillar 23 of the building.

A mounting post 25 is rotatably mounted on the pedestal 22 via a swivel base 24.

26 is a drive device that drives the distributor device 21.

27 is a first part whose base is pivotally supported on the upper part of the mounting post 25, and the first part 16 of the boom device 11
is the same as

28 is an undulation cylinder installed between the mounting post 25 and the first portion 27.

14c is a building concrete transfer pipe. Note that 29, 29 are hooks provided on the arm portion 10.

To explain the case where the present invention has the above-described configuration and uses the arm portion 10 as a concrete distributor device 21 by removing the arm portion 10 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 20, and then remove the pins 18, 18...
..., remove nuts 19, 19...

Next, hook 2 of arm part 10 with a crane etc.
9, 29 and lift it up, and attach the first part 27, which is pivoted to the upper part of the mounting post 3 on the pedestal 22 attached to the pillar 23 of the building, and the second part 17 on the arm part 10 side to the pin 18. Twist and join.

Subsequently, the concrete transfer pipe 14c of the building and the front end concrete transfer pipe 14b on the arm portion 10 side are connected by a coupling 20.

As described above, the distributor device 21 can be rotated and raised by the drive device 26 attached to the pedestal 22 of the pillar 23 of the building, and concrete can also be placed by pumping the concrete. , can be used as a concrete distributor device 21.

Next, remove the arm portion 10 from the pedestal 22,
When installing on the vehicle body 1, the above steps may be performed in reverse order.

As described above, according to the present invention, the base boom is composed of the first part whose base end is pivotally supported on the mounting post, and the second part whose distal end is pivotally supported on the base end of the tip boom,
The tip of the first part and the base of the second part can be attached and detached by means of a mounting bracket, and extend from the concrete pump and the tip side concrete transfer pipe that penetrates the shaft support of the base boom and the tip boom, and connect the mounting post and the base. If the arm part is attached to a concrete pump vehicle by connecting the base-side concrete transfer pipe that penetrates the boom and the shaft support with a coupling between the base booms, it can be used as a concrete pump boom vehicle, and it can be removed. In some cases, it can be attached to a building pillar or crane post and used as a concrete distributor to improve operating efficiency.
