A needle beam trolley

Abstract

A needle beam trolley, comprising: a hydraulic source, an anti-floating jack, a vertical oil cylinder, a support, a demoulding cylinder, a concrete pouring assembly, and a main body of the trolley; the concrete pouring assembly includes a pouring joint, a pouring valve, and the pouring joint It includes a drainage surface, a raised area, a pressure relief element, a pressure relief spring, and a pressure relief channel; the drainage surface guides the oblique flow of concrete so that a shielding area appears on the pouring surface, and the pressure relief channel includes a pouring joint section and a pouring valve Section; the end of the pouring valve section is provided with a discharge port, and the pouring valve includes a sealing plate, a valve plate, a valve stem, a driving device, a pivot, a valve sleeve, a flange sleeve, a support plate, a valve body, and the valve stem Including a first shaft section and a second shaft section, the valve plate includes a first guide surface, a second guide surface, a blanking port, a first passage section, a second passage section, a third passage section, a blanking ball, a drop material spring.

Description

technical field [0001] The invention relates to the field of inverted siphon engineering, in particular to a needle-beam trolley. Background technique [0002] With the advancement of science and technology, the problem of uneven distribution of water sources has become prominent. For arid areas, it is particularly important to build long-distance canals or waterways to dispatch water from areas with abundant water sources to water diversions and downstream along the way. When the channel encounters a road or a river ditch that crosses the plane, it is usually solved by the inverted siphon technology, so that the water passes under the road or the ditch. The inverted siphon project has the advantages of convenient construction and low cost. Inverted siphon technology has been used in many places in my country, and inverted siphon projects have been arranged to transmit water resources through inverted siphon tunnels in straight and inclined sections. In inverted siphon eng...

AI Technical Summary

Problems solved by technology

[0005] 2. The needle-beam trolley in the prior art is equipped with a pressure relief structure for the excessive expansion in the concrete pouring process. However, only the pressure relief is considered, and the discharge after the pressure relief is not considered, which often leads to the random discharge of the pollution trolley

[0006] 3. The needle-beam type trolley in the prior art, the pouring nozzles all spray concrete directly, without considering the flow direction of the concrete after spraying, and cannot accurately control the flow direction of the concrete

[0007] 4. The needle beam trolley of the prior art has a valve to control the pouring during the pouring process. However, the pouring material often remains on the valve, which will soon pollute the valve plate and affect the further use of the valve plate.

[0008] 5. The needle beam trolley in the prior art has a small pouring nozzle, and it is difficult to process or realize more functions

[0009] 6. The pouring valve of the prior art causes sewage to flow sideways during cleaning, and it is difficult to have a good cleaning method to collect sewage
