Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a frame of a concrete pump car that doubles as a water tank for storing water used for cleaning around the concrete pump after the concrete is placed. It is about.

[Prior Art] In a conventional concrete pump car, a pedestal (deck frame) is placed on a truck chassis, on which a concrete pumping mechanism for sucking and discharging concrete by a concrete pump, a slewing pedestal for supporting a boom to freely swing,
Equipped with front and rear outriggers, concrete piping for pumping concrete discharged from the concrete pumping mechanism, etc., and further discharging residual concrete in the concrete pipe after the concrete placing work, concrete pumping mechanism Install a water tank on the deck frame to store the cleaning water necessary to remove the concrete adhering to the deck, and use the water pump to remove the water from the water tank and use it for cleaning. There is.

[Problems to be solved by the invention] However, in the conventional concrete pump vehicle, since the concrete pump and the like are mounted on the truck chassis, the deck frame for mounting these is indispensable. Since the water tank is mounted on the deck frame, not only does the presence of the deck frame increase the overall height of the concrete pump car, but the water tank occupies a large area on the deck frame. The space was getting smaller.

Therefore, an object of the present invention is to reduce the overall height of a concrete pump car and to eliminate the space occupied by a water tank on the frame.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a water pump installed on the frame, wherein the frame of a crane carrier is also used as a water tank formed by dividing the frame. The inside of the water tank is connected via a pipe, and the concrete pumping mechanism or the like is placed on the frame that also serves as the water tank.

[Operation] In the case of a crane carrier, as compared with a truck chassis, the crane carrier is configured to be able to carry an upper object as it is and has a sufficient space. Therefore, if the frame of the crane carrier is also used as a water tank, the frame can be used. Since it is not necessary to put a water tank on the space, the space can be effectively used, and since the conventional deck frame is not required, the concrete pump car can be easily manufactured.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention, in which a room is partitioned and formed in a corridor shape in the peripheral portion of the rear half of the frame 1 of the crane carrier supported by the front wheels 2 and the rear wheels 3. The water tank 4 is constructed as a sealed structure so as not to leak, the frame 1 of the crane carrier in the latter half part also serves as a water tank, and a water pump 5 is installed on the upper surface of the frame 1 and the water pump 5 The inside of the water tank 4 is connected to the inside of the water tank 4 by the pipe 6, and the water in the water tank 4 is taken out by the water pump 5 as wash water so that it can be used.

Although not shown, in the present invention, on the frame 1 of the crane carrier, a concrete pumping mechanism for sucking and discharging concrete in the hopper with a concrete pump, a swing platform for supporting a boom, Front outriggers and rear outriggers, etc. are mounted directly on each other, and concrete pipes connected to the concrete pump discharge side of the concrete pumping mechanism are supported along the boom so that a remote location via the boom,
Alternatively, make a concrete pump car that allows concrete to be cast in high places.

When the water tank 4 is formed inside the frame 1 of the crane carrier and the frame 1 and the water tank 4 are also used, the wide internal space of the frame 1 which has not been used so far can be effectively used, It is possible to make a large water tank, and it is possible to eliminate the need to separately install a water tank on the upper portion of the frame 1, thus making it possible to use a large space on the upper surface of the frame 1. Further, since the concrete pumping mechanism or the like can be directly mounted on the frame 1 which is also used as the water tank 4, the deck frame mounted on the track chassis as in the conventional concrete pump truck can be omitted, and the deck frame can be omitted. The total height can be reduced by the height of the height of the concrete pump, the center of gravity of the concrete pump car can be lowered, the stability can be increased, the number of parts can be reduced, and the number of manufacturing steps and the cost can be reduced.

[Advantage of the Invention] As described above, according to the frame of the concrete pump vehicle of the present invention, the frame of the crane carrier, which has not been considered in the past, is used as it is as the frame of the concrete pump vehicle, and at the same time, the internal space of the frame is Since it has a sealed structure and doubles as a water tank,
The frame of the crane carrier can be effectively used, and the water tank to be mounted on the frame can be omitted,
In addition, the frame is made to be robust and the top surface can be loaded with objects, so it is possible to directly use the concrete pump etc. as a water tank without using the deck frame which was indispensable in the conventional concrete pump truck. It can be mounted on the top, and a concrete pump truck can be easily manufactured, and other excellent effects can be obtained.
