Embodiment 1

[0034] This embodiment takes the cleaning construction of the concrete that is bonded to the inner wall of the concrete delivery pump pipe 2 used in the construction process of a super high-rise building 1 as an example, and describes in detail the cleaning device for the concrete delivery pump pipe of a super high-rise building of the present invention. The height of 1 is about 500 meters, and the diameter of concrete delivery pump pipe 2 is 250mm.

[0035] Combine below Figure 1 to Figure 4 Illustrate the cleaning device of the super high-rise building concrete delivery pump pipe of the present invention, it comprises: the vertical vibrating mechanism 10 that coaxially arranges and connects successively, lateral support positioning mechanism 20 and pump pipe dredging and cleaning mechanism 30, wherein,

[0036] The vertical vibration mechanism 10 includes a mounting base 11 and a mounting base 2 12 arranged parallelly and at intervals up and down, a vibration motor unit 15 ...

Embodiment 2

[0045] Different from Example 1, as image 3 As shown, the cleaning device of the super high-rise building concrete delivery pump pipe also includes a lifting mechanism 50, which includes a rectangular support frame 51, a lifting motor 53 fixed on the outside of the support frame 51, a rotating line fixed in the support frame 51 and arranged in parallel. Rod 54 and positioning concave wheel 55, the rotating wire rod 54 that is wound with traction steel wire rope 56 is connected with the rotating shaft of lifting motor 53, and the other end of traction steel wire rope 56 walks around positioning concave wheel 55 and is fixed on the mounting base-11 top multiple connected with a tension steel ring 16 for lifting or lowering the connected vertical vibration mechanism 10, lateral support positioning mechanism 20 and pump pipe dredging and cleaning mechanism 30. In this embodiment, the end of the traction wire rope 56 has four wire rope branches, and each wire rope branch end is co...

Embodiment 3

[0048] In this embodiment, taking the cleaning construction of the concrete that is bonded to the inner wall of the concrete delivery pump pipe 2 used in the construction process of a certain super high-rise building 1 as an example, the cleaning method of the super high-rise building concrete delivery pump pipe of the present invention is described in detail. The specific steps are as follows:

[0049] After the vertical vibrating mechanism 10, the lateral support positioning mechanism 20 and the pump pipe dredging and cleaning mechanism 30 arranged coaxially and connected in sequence are put into the inner cavity of the concrete delivery pump pipe 2, the lateral support positioning mechanism 20 enters the working state, and the multiple The reverse force generated by the pressure of the support positioning spring 24 drives the guide roller 28 against the inner wall of the concrete delivery pump pipe 2 to maintain stability, ensuring that the pump pipe dredging and cleaning mec...

Abstract

The invention discloses a clearing device and method for a concrete conveying pump pipe of super high-rise building. The problems that concrete bonded to the inner wall of the concrete conveying pumppipe cannot be difficultly and thoroughly cleaned up through an existing water clearing mode, and the construction progress is influenced are solved. The device comprises a vertical vibration mechanism, a lateral supporting and positioning mechanism and a pump pipe dredging and clearing mechanism which are coaxially and sequentially connected, wherein a coarse grinding wheel support and a fine grinding wheel support of the pump pipe dredging and clearing mechanism are driven by a rotating motor to do circular motion along the inner wall of a pipeline, and the concrete on the inner wall of thepipeline is removed through rotating grinding of the coarse grinding wheel and vertical vibration impact of the fine grinding wheel; two installing bases of the vertical vibration mechanism are flexibly connected through a spring type connecting piece arranged between the two installing bases, and a vibration motor set drives the pump pipe dredging and clearing mechanism to vibrate back and forthalong the axis of the pipeline; and a plurality of support positioning springs and guide rolling wheels are uniformly distributed on a guiding rod of the lateral supporting and positioning mechanism in the radial direction, and the guide rolling wheels are driven to prop against the inner wall of the pipeline by reverse acting force generated by pressing the support positioning springs.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cleaning device and method for concrete delivery pump pipes applied to super high-rise buildings. Background technique [0002] With the development of social economy, the number of super high-rise buildings is increasing, and the height of super high-rise buildings is mostly 300-500 meters. In the conveying pump pipe, the concrete circulates and outputs along the concrete conveying pump pipe at a height of several hundred meters, so as to complete the concrete pouring construction of each floor. However, due to the long construction period of super high-rise buildings and the high utilization rate of concrete delivery pump pipes, if the concrete delivery pump pipes are not cleaned in time, more and more concrete may be bonded to the inner wall of the pipeline, causing the entire concrete delivery pump pipe to be damaged. The width of the inner diameter is differ...
