Description

Technical Field

[0001] The present application relates to the technical field of concrete construction, and more specifically, to a sealing structure for a hose interface of a concrete placing machine. Background Art

[0002] The end of the existing concrete pouring pump's pump pipe is open during construction unloading. When the pouring pump is turned off, a small amount of concrete will remain in the pump pipe. Since the pump pipe is poured vertically, when the pouring point is transferred, the concrete in the pump pipe will spill onto the unconstructed slab surface, causing a "stain" on the bottom of the concrete slab. Some pump pipes are equipped with a manually operated stop valve at the end to solve the stain problem. The single-handed operation of the placing machine driver to go back and forth between the placing machine cab and the end of the pump pipe will inevitably reduce the pouring efficiency; the cooperation of two or more people will have certain safety hazards. The existence of a visual blind end will cause the placing machine driver to transfer the pump pipe before the stop valve operator leaves, accidentally injuring the operator.

[0003] A concrete placing machine soft-mouth plugging device disclosed by searching the publication number CN216641451U includes a rectangular tube, which is sleeved on the outside of the end of an existing pump pipe, and the end of the rectangular tube is rotatably connected with a split-type plugging plate, and a reset mechanism is provided between the plugging plate and the pipe wall of the rectangular tube. The device installs a spring-controlled opening and closing plate at the end of the existing pump pipe, does not require manual participation, effectively ensures personal safety, and improves construction efficiency.

[0004] However, this application has certain shortcomings. After long-term use, the left and right sealing plates are impacted by the internal concrete, and gaps are likely to appear when closed, causing a small amount of concrete in the pump pipe to easily flow out. In addition, the reset mechanism, that is, the spring, is exposed to the outside. When the concrete flow in the pump pipe is large, the concrete is likely to splash up and adhere to the surface of the spring, affecting its rebound effect. After a long period of this situation, the left and right sealing plates cannot be restored to their original position.

[0005] In order to solve the above problems, the present application provides a concrete placing machine hose interface plugging structure. Utility Model Content

[0017] Furthermore, baffles are integrally formed on both sides of the flow plate, and the two baffles are perpendicular to the flow plate.

The remaining concrete in the pump pipe can be recovered through the installation groove. When a gap appears between the two sealing plates, the remaining concrete in the pump pipe can also be recovered through the installation groove to prevent it from leaking.
