Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention will be further described
[0022] figure 1 It is a schematic diagram of the working state of the pump truck for short-distance pumping of concrete before the implementation of the present invention.
[0023] The figure shows that before the implementation of the present invention, when carrying out short-distance pumping, all booms are either deployed for pumping construction, or the end boom is curled up to use an auxiliary unloading device and an additional unloading hose for construction.
[0024] figure 2 It is a schematic diagram of the working state of the pump truck for short-distance pumping of concrete after the implementation of the present invention.
[0025] The figure shows that after the implementation of the present invention, when performing short-distance pumping, only part of the boom at the head end needs to be curled up, and part of the boom at the end is used to carry out the ...

The invention provides a method for the concrete pump truck to realize the pumping construction by using only part of the end booms without deploying all the booms during the short-distance pumping construction. At present, when the concrete pump truck is in construction, it needs to expand the boom of tens of meters. When pumping in a short distance, it can be pumped by curling up part of the end boom, adding an auxiliary unloading device and an additional unloading hose. This short-distance pumping mode of adding an additional unloading device and a curled-up end boom is not only complicated in structure and difficult to realize. And it will have a serious impact on the force of the boom. Aiming at the above deficiencies, the present invention proposes to use part of the boom without curling up the end boom during short-distance pumping, and does not need to add auxiliary unloading devices and additional unloading hoses on the boom, so that the boom can be operated under a reasonable load. A method to achieve short-distance pumping under force conditions. In the method, the pipe switching device arranged at the turret of the boom is used to switch the piping of the boom. It is more reasonable and practical to select all booms for long-distance pumping and select some booms for short-distance pumping.
Description
technical field [0001] The invention relates to a concrete pump truck, in particular to a short-distance pumping concrete method for the concrete pump truck. Background technique [0002] The pump truck that is widely used in concrete pouring now needs to expand the boom of tens of meters during the pumping operation. Under the high pressure of the pumping system, the concrete is pumped to the place of use through the boom pipe installed on the boom. Since the hinge shaft between the booms and the elbow in the boom piping are on the same axis, the boom and the boom piping can be curled up or unfolded under the control of the boom cylinder. [0003] When the concrete pump truck is carrying out pumping construction with a large elevation or span, it needs to expand the boom of tens of meters to realize the pumping construction. When the pumping concrete elevation or span is not large, only part of the jib is required for construction. At this time, part of the end boom is c...
