Spiral vibrating mortar pump

Abstract

The invention discloses a spiral vibrating type mortar pump. The spiral vibrating type mortar pump comprises two parts: an underframe and a grouting pump which is arranged on the underframe, wherein the grouting pump is composed of a power output mechanism and a pump body; the motor output shaft end in the power output mechanism is connected to an end cam, and the end cam is connected to the pump body through a hinge plate; a truss and a truss track which is fixed on the underframe are arranged at the lower end of the pump body, wherein a reset spring is arranged between the truss and the underframe; the truss and the truss track can move relatively; the truss, the truss track and the end cam form a cam mechanism. The hinge plate is mainly composed of a main hinge plate which is coaxially connected to the end cam and an assistant hinge plate which is coaxially connected to a spiral rod of the pump body; main hinges on the main hinge plate are hinged to assistant hinges on the assistant hinge plate; the assistant hinge plate moves relative to the main hinge plate along the axial direction of the assistant hinge plate; and a profile curve on the end cam is divided into a slow-forward part and a quick-return part. The spiral vibrating type mortar pump disclosed by the invention is compact and simple in structure, the slurry pouring efficiency is relatively high, and the power consumption is small.

Description

technical field [0001] The invention belongs to the technical field of pouring mechanical equipment for building construction, and in particular relates to a spiral vibrating mortar pump. Background technique [0002] Mortar pump is the supporting equipment commonly used in grouting or grouting projects for conveying cement slurry or mortar in construction. It is mainly used for pressure grouting in reservoirs, river soil, cracks, divergent layers, and karst caves of earth-rock dam foundations in water conservancy projects. And anchor rod grouting cement mortar to achieve the purpose of solid connection, anti-seepage and anti-leakage. It can also be used to transport solid-liquid mixed slurry such as lime slurry and clay mortar in the construction of national defense projects, civil air defense projects, mines, and tunnels. The combination of mortar pump and mixer can continuously grout and convey during construction. The various mortar pumps currently used mostly use plung...

AI Technical Summary

Problems solved by technology

For the screw mortar pump, the working principle is that the single-head screw is the rotor, and the double-head screw is the stator. The rotor rotates eccentrically around the stator axis in the stator, so that the slurry is continuously sucked and discharged. Due to the screw The rod is generally longer, and the hopper on the pump body is larger, and the screw mortar equipment occupies a larger area.
