Description

Technical Field

[0001] The utility model belongs to the technical field of concrete distribution, and in particular relates to a top-mounted distribution device. Background Art

[0002] The concrete placing boom is the terminal equipment for pumping concrete when the building machine is placing concrete. It is mainly used to transport the pumped concrete through the delivery pipe to the formwork where the components need to be cast. The placing device of the traditional placing boom is supported by a bracket. The placing device includes two parts of the placing pipe. The combined movement of the two parts of the placing pipe can cover all the placing points within the placing radius. However, since the cantilever length of the placing pipe is relatively long, it is necessary to add a balance block to the rear end of the placing device to balance the force. In addition, since the bracket has a certain height, the placing boom needs to be set above the ceiling of the building machine to obtain enough space to accommodate the placing boom. When placing concrete, it is necessary to extend the discharge end of the placing pipe from the hole on the roof to place concrete in the formwork. After the concrete reaches the limit range, it is pulled out from the hole and continues to extend from other holes.

[0003] However, the repeated action of extending and pulling out the discharge end greatly affects the flexibility and working efficiency of the concrete placing boom. In addition, the bottom of the bracket installation position is difficult to cast, and there is a dead angle for placing the concrete. The setting of the balance block increases the overall weight, further affecting the flexibility of the concrete placing boom. Utility Model Content
