Description

  The present invention relates to a concrete pump truck used at a construction site such as a building.

  Conventionally, ready-mixed concrete used at a construction site is transported from a factory to a construction site by a concrete mixer truck, and the ready-mixed concrete is placed at a predetermined site using a concrete pump car at the construction site.

For this reason, since transport by concrete mixer truck is transported in the state of ready-mixed concrete, there is a disadvantage that the quality of ready-mixed concrete is deteriorated depending on the transport time to the construction site, and transport of ready-mixed concrete with water added. For this reason, there is a drawback that the weight is heavy and the transportation efficiency is poor.
In addition, it is necessary to use a concrete pump truck that pumps the ready-mixed concrete transported by the concrete mixer truck to the construction site at the construction site, and it is necessary to dispatch a concrete mixer truck and a concrete pump truck. At the same time, there was a drawback of high cost.
nothing special.

  In view of the above-described conventional drawbacks, the present invention transports dry concrete, which is a mixture of cement and sand set in advance other than water, to a construction site by a generally used truck, and obtains water and dry water obtained on site. Concrete is mixed with a concrete mixer in the loading platform to produce ready-mixed concrete, and this ready-mixed concrete can be pumped to the placement site with a concrete transport pipe via a hopper and pump installed on the loading platform, and efficiently dried to the site. An object of the present invention is to provide a concrete pump truck that transports concrete and that can be used economically without the need for a concrete mixer truck, in which the produced ready-mixed concrete can be placed in a short time.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

  To achieve the above object, the present invention provides a concrete mixer for producing ready-mixed concrete installed in a truck or trailer loading platform, and a hopper installed in the loading platform to receive ready-mixed concrete discharged from the concrete mixer. And a pump that pumps the ready-mixed concrete in the hopper with a ready-mixed concrete transport pipe attached to a boom that can be folded and housed in the loading platform.

  As is clear from the above description, the present invention has the following effects.

(1) A concrete mixer for producing ready-mixed concrete installed on a truck or trailer loading platform, a hopper installed on a loading platform to receive ready-mixed concrete discharged from the concrete mixer, and ready-mixed concrete in the hopper. It consists of a pump that pumps with a ready-mixed concrete transport pipe attached to a boom that can be folded and stored in the loading platform, so that dry concrete is transported to the construction site and ready-mixed with water obtained at the construction site. And the produced ready-mixed concrete can be pumped to the placement site by a ready-mixed concrete transport pipe via a hopper and a pump.
Therefore, the ready-made concrete can be placed in a short time, and it is possible to reliably prevent problems such as time-consuming transport to the construction site due to traffic jams, etc. Can do.

(2) According to the above (1), since dry concrete may be transported to the construction site by truck, a special vehicle such as a conventional concrete mixer truck is unnecessary and can be transported at low cost.

(3) Since the concrete mixer, hopper, pump, and ready-mixed concrete transport pipe are installed in the loading platform according to (1) above, it is only necessary to bring them into the construction site, making arrangements easy and performing the work as scheduled. be able to.

(4) Claim 2 can also be operated efficiently because the same effects as in the above (1) to (3) can be obtained and a power source such as a concrete mixer, pump, boom, etc. is also installed in the loading platform. .

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the first preferred embodiment for carrying out the present invention shown in FIGS. 1 to 4, 1 manufactures ready-mixed concrete on the loading platform 3 of the truck 2 and pumps the manufactured ready-mixed concrete to the placing site. The concrete pump truck 1 is a concrete pump truck according to the present invention, and the concrete pump truck 1 is discharged from the concrete mixer 6 and a concrete mixer 6 installed through a support base 5 near the rear wheels 4 and 4 of the loading platform 3. The ready-mixed concrete can be folded and stored between the hopper 7 installed on the loading platform 3 and the concrete mixer 6 installed on the front portion of the loading platform 3 so that the ready-mixed concrete can be guided from the support platform 5 in the forward direction with an inclined surface. A possible boom 8, a ready-mixed concrete transport pipe 9 attached to the boom 8, and the inside of the hopper 7 connected to the ready-mixed concrete transport pipe 9. A pump 11 attached to the hopper 7 for pumping the ready-mixed concrete 10, a water tank 12 installed on the cargo bed at a lower position of the folded boom 8, and a rear end portion of the cargo bed 3 A crane 14 for carrying out operations such as transporting the dry concrete 13 etc. to the concrete mixer 6, and a drive source for driving the concrete mixer 6, pump 11, boom 8, etc. provided at the rear part of the loading platform 3. A generator 15 and a compressor 16, a work table 17 installed on the loading platform 3 in the vicinity of the concrete mixer 6, and front and rear outriggers 18, 18 provided near the front and rear portions of the loading platform 3. It is configured.

The concrete pump vehicle 1 configured as described above moves to the construction site, and the loading platform 3 is installed in a fixed state on the ground by the front and rear outriggers 18 and 18.
In this state, the dry concrete 13 that has been measured and packaged in advance in a factory, such as cement and sand, is put into the concrete mixer 6 by using the crane 14 and the water obtained on site is set in advance. The measured amount is charged and the concrete mixer 6 is driven to produce the ready-mixed concrete 10. The ready-mixed concrete 10 produced by the concrete mixer 6 falls into the hopper 7 by being discharged from the lower discharge port 6a, and is pumped from the hopper 7 through the pump 11 through the ready-mixed concrete transport pipe 9, and the tip portion is It pumps from the front-end | tip part of the ready-mixed concrete transport pipe 9 of the front-end | tip part of the boom 8 located in the placement site to a placement site.

When the ready-mixed concrete is being pumped, the ready-mixed concrete is produced by the concrete mixer 6, and the ready-mixed concrete is sequentially pumped to the setting site to efficiently perform the setting.
Cleaning of the concrete mixer 6, the hopper 7, the ready-mixed concrete transport pipe 9 and the like is performed in the same manner as before.
