Blocking device for concrete conveying pipe pouring port and connection structure of blocking device

Abstract

The invention discloses a blocking device for a concrete conveying pipe pouring port and a connection structure of the blocking device. The blocking device comprises a barrel pipe provided with a baffle capable of closing or opening a discharge outlet of the barrel pipe. When the discharge outlet of the barrel pipe is closed, the baffle and the barrel pipe are in locking connection through a locking component. The concrete conveying pipe pouring port in the connection structure is composed of an annular ring made of hard materials. The outer side wall of the annular ring is provided with circumferential connection grooves. The blocking device in the connection structure is the blocking device for the concrete conveying pipe pouring port. The part, close to the discharge outlet end, of the outer side face of the barrel pipe is provided with circumferential connection grooves. The concrete conveying pipe pouring port and a feed inlet of the blocking device are connected in a sealing and butt-joint mode through a clamp. According to the blocking device for the concrete conveying pipe pouring port and the connection structure of the blocking device, in the moving process of the concrete conveying pipe pouring port, concrete in a concrete conveying pipe is not liable to be leaked through the blocking device, and the concrete conveying pipe pouring port and the clocking device are connected in a sealing mode very easily.

Description

technical field [0001] The invention relates to a construction tool, in particular to a plugging device for a pouring port of a concrete delivery pipe and a connection structure thereof. Background technique [0002] During the construction process of concrete pumping, if the pouring port of the concrete delivery pipe is not effectively blocked when the pouring site needs to be transferred, during the transfer process, the residual concrete will be spilled on the unconsolidated site, the lower ground or floor, scaffolding and On parts such as safety nets and formwork, when the spilled concrete is covered by the post-poured concrete, there may be appearance quality problems such as color difference and holes; the spilled concrete itself causes waste, and it requires additional labor and labor to clean it up. The cost of transport machinery increases the cost of expenditure. If there are operators under the concrete delivery pipe during the transfer process, there will be safe...

Problems solved by technology

[0007] Second, because the end face of the discharge port is a combined surface with symmetrical slopes on both sides of the boundary, the baffle plate corresponds to the combined surface, so such an end face of the discharge port has brought great difficulties to the production. Inconvenient, increases manufacturing cost
