Embodiment 1

[0038] A telescopic tube group, see figure 1 , including a fixed bracket 1, a tube group 2 and a telescopic tube 6; the tube group 2 is slidably arranged on the fixed bracket 1, and the telescopic tube 6 is connected to the tube group 2, the details are as follows:

[0039] The tube group 2 includes at least two stretchable single tubes arranged in series, and the single tube may be composed of multiple U-shaped pump tubes and straight tubes; the adjacent single tubes are flexibly connected by a connecting piece 3; the tubes Group 2 includes a plurality of highest points on plane A and a plurality of lowest points on plane B, and plane A and plane B are parallel to each other.

[0040] The connecting piece 3 is a combination of a pipe clip and a sealing ring.

[0041] The fixed bracket 1 includes a base plate 1.1 and a slide rail 1.2 arranged on the base plate 1.1, and a single tube in the tube group 2 is slidably arranged on the slide rail 1.2 through a supporting trolley 1....

Embodiment 2

[0051] The difference between embodiment 2 and embodiment 1 is that the fixed bracket 1 includes a fixed bottom plate 1.4, a fixed top plate 1.5 and a C-shaped guide rail 1.6 arranged on the fixed top plate 1.5, see Figure 4 . The fixed top plate 1.5 is located above the fixed bottom plate 1.4, and the single tube in the tube group 2 is slidably arranged on the C-shaped guide rail 1.6 through the T-shaped movable group 1.7. The T-shaped movable group 1.7 can drive the whole tube group 2 to slide along the C-shaped guide rail 1.6 to realize expansion and contraction. The power of sliding can be mechanical (oil cylinder, cylinder, etc.), also can be manual. T-shaped movable group 1.7 can be T-shaped slide block, also can be block and pulley.

Embodiment 3

[0053] A concrete placing machine, comprising the telescopic tube group as described in embodiment 1 or embodiment 2, the whole telescopic tube group is set on the concrete placing machine trolley, and the trolley drives the entire telescopic tube group to move back and forth.

Abstract

The invention provides a telescopic pipe set, which comprises a fixing support and a pipe set body. The pipe set body is slidably arranged on the fixing support; the pipe set body comprises two or more segments of single pipes telescopically arranged in series, and the adjacent single pipes are movably connected by connecting pieces; and the pipe set body comprises a plurality of highest points located on the plane A and a plurality of lowest points located on the plane B, and the plane A and the plane B are parallel to each other. By applying the technical scheme, the telescopic pipe set hasthe effects that the structure is simple, extending-retracting adjustment is facilitated, and the construction requirements of concrete pouring are met. The invention further provides a concrete distributing machine, which comprises the telescopic pipe set. The invention further provides a trolley, which comprises the concrete distributing machine.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a telescopic pipe group, a concrete placing machine and a trolley. Background technique [0002] During the tunnel construction process, it is necessary to use material conveying pipelines and clean material conveying pipelines, and the pipeline system is complex. [0003] The pumping pipelines in each pipeline system are connected by pipe clamps and sealing rings, and then fixed on the trolley by the fixing frame. When changing the pumping position during construction, the concrete pumping interface needs to be replaced, and the pumping of concrete needs to be stopped. Several people work together to first remove the tube clamp, sealing ring, and pump tube on the pump tube. After replacing the pump tube with a suitable length and adjusting the position of the pipeline outlet, install and fix it again after docking with the next pumping interface, and then continue P...
