Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete pump pipe conveying technology, specifically to a device for preventing mortar leakage at the inlet of a concrete pump. Background Technology
[0002] Modern construction projects often require the pouring of slab-like concrete structures. The most commonly used concrete structures on construction sites are walls and columns with roof slabs. Workers need to place the pump pipe above the wall or column to be poured. When confirming the pouring, the worker turns on the switch, and the concrete in the pump pipe flows into the wall or column. After the pouring is completed, the worker stops the pouring and moves the pump pipe to the next place that needs to be poured.
[0003] During the concrete pouring process, the construction sequence is to pour the walls and columns first, followed by the beams and slabs. During the movement of the pump pipe, due to vibration and other reasons, a small amount of concrete adhering to the pump pipe may spill onto the slab formwork surface. Since the slab reinforcement has been tied, the concrete spilled onto the slab formwork surface is not easy to clean, and cold joints may easily form between it and the subsequently poured beam and slab concrete, affecting the quality of the concrete pouring.
[0004] In the prior art, such as the patent with publication number CN217108270U, a pump pipe anti-leaking device is disclosed, including a pump pipe body. An ash outlet is provided at the end of the pump pipe body. A sheet metal mounting sleeve is welded to the outer wall of the pump pipe body near the ash outlet. A pre-reserved rectangular hole is formed on the surface of the sheet metal mounting sleeve. A pre-reserved hole is also provided on the outer surface of the sheet metal mounting sleeve above the pre-reserved rectangular hole. A fixing base block is fixedly connected to one end of the sheet metal mounting sleeve, and a knife switch body is movably disposed inside the fixing base block.
[0005] The aforementioned patent requires pre-welding sleeves to the pump pipe, which is laborious to install and disassemble. It is also difficult to adapt to pump pipes of different sizes, which will cause inconvenience in actual implementation and make it difficult to seal residual ash in the pump pipe.

Corresponding locking components are movably connected in the multiple bolt holes. A positioning clip is provided on one end of the locking component facing the axis of the cylinder.
[0009] The chuck includes a dust baffle, which is a semi-circular plate component. The radius of the dust baffle is equal to the radius of the cylinder. After the two chucks are closed, they fit against the bottom surface of the cylinder to form a sealing surface.
[0010] The chuck also includes a limiting plate, an operating lever, and fasteners. A limiting plate is provided on one side of the arc surface of the ash baffle plate. Fasteners are fixedly provided at both ends of the arc-shaped structure on the limiting plate. An operating lever is fixedly provided at the end of the limiting plate away from the cylinder.

A locking component 22 is provided on the hanging clamp 2. Two chucks 3 are coaxially provided on the lower bottom surface of the cylinder 1. The chucks 3 are movably connected to the cylinder 1 through a chuck groove 11 fixedly provided on the outer edge of the lower bottom surface of the cylinder 1.
[0022] The connecting part 21 is fixed to the cylinder 1 and the hanging clamp 2 by welding.
[0023] The hanging clamp 2 is parallel to the bottom surface of the cylinder 1. Multiple bolt holes are reserved at equal intervals on the surface of the hanging clamp 2. Corresponding locking components 22 are movably connected in the multiple bolt holes. A positioning card 221 is provided on one end of the locking component 22 facing the axis of the cylinder 1.
[0024] The positioning clip 221 can be set as a rubber pad to avoid rigid contact with the pump pipe 5. The positioning clip 221 and the locking member 22 can be movably connected. The positioning clip 221 is stationary relative to the pump pipe 5, and the locking member 22 is a bolt rod and is rotatably connected in the bolt hole.
[0025] The chuck 3 includes a dust-blocking plate 33, which is a semi-circular plate component. The radius of the dust-blocking plate 33 is equal to the radius of the cylinder 1. After the two chucks 3 are closed, they fit against the bottom surface of the cylinder 1 to form a sealing surface.
