Embodiment Construction

[0016] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0017] Such as figure 1 As shown, the present invention provides a concrete placing machine, comprising a column 13, a second horizontal turning mechanism 14 is provided at the top of the column 13, and a second pin is passed between the front end of the boom of the concrete placing machine and the second horizontal turning mechanism 14. The shaft 15 is movably connected so that the boom of the concrete placing machine can rotate vertically, and one end of the second oil cylinder 5 is rigidly connected to the second horizontal turning mechanism 14, and the other end is rigidly connected to the boom of the concrete placing machine.

[0018] which, combined with figure 2 , the boom of the concrete placing machine includes a first placing boom 1 and a second placing boom 2, a conveying pipeline 9 is provided on and at the connectio...

Abstract

The invention relates to a concrete spreader boom, which comprises a first spreading rod and a second spreading rod, wherein a delivery pipeline is connected between the first spreading rod and the second spreading rod. The concrete spreader boom is characterized in that a first horizontal slewing mechanism is arranged at the tail end of the first spreading rod, a slewing head capable of slewing horizontally is arranged on the first horizontal slewing mechanism, and the front end of the second spreading rod is movably connected with the slewing head so that the second spreading rod can slew vertically. The invention further provides a concrete spreader provided with the concrete spreader boom. The concrete spreader boom is simple in structure, and joints of various sections of the boom can pitch and slew simultaneously. Cost of the concrete spreader utilizing the concrete spreader boom is controlled well.

Description

technical field [0001] The invention relates to a concrete distribution construction machine, which belongs to the technical field of building construction machines. Background technique [0002] With the rapid development of building construction technology, for group buildings and high-rise buildings, towed concrete pump trucks or concrete pump trucks are generally used to transport concrete to the construction site. Concrete pump trucks have the advantages of flexible movement and convenience, but their disadvantages are high cost and more limited conveying height compared with towed concrete pumps, while towed concrete pumps have the advantages of simple structure and low cost, and the conveying height is relatively high. Much higher than concrete pump trucks. At present, for high-rise buildings higher than 80 meters, it is still difficult for concrete pump trucks to transport concrete to this height. On the contrary, towed concrete pump trucks can construct high-rise ...
