Swing-type gap grouting device for building

Abstract

The invention discloses a swing-type gap grouting device for a building and relates to the technical field of building equipment. The problem is solved that in the grouting process of a spray nozzle,the spray nozzle and the inner wall of a gap are in contact for a long time, and accordingly the spray nozzle is easily damaged. The swing-type gap grouting device is characterized by comprising a main box, a semi-elliptical slide rail fixedly connected with the inner wall of the main box, a slide block slidingly connected with the semi-elliptical slide rail, a swing rod, a spray nozzle and a driving assembly for driving the slide block to move in the arc track direction of the semi-elliptical slide rail; one end of the swing rod is rotatably connected with the slide block, and the other end of the swing rod is fixedly connected with the spray nozzle; a fixing shaft is fixedly connected to the inner wall of the main box, and a slide groove for the fixing shaft to be inserted in is formed in the swing rod; a hydraulic pump is fixedly connected to the inner wall of the main box, a conveying pipe is arranged between the hydraulic pump and the spray nozzle, and a swing groove for the spraynozzle to swing in runs through the bottom of the main box. The swing-type gap grouting device has the advantages that the spray nozzle does not abut against the inner wall of the gap in the groutingprocess, and the service life of the spray nozzle is prolonged.

Description

technical field [0001] The invention relates to the technical field of construction equipment, more specifically, it relates to a swing type gap grouting device for construction. Background technique [0002] The grouting machine is a professional construction tool for chemical grouting plugging and structural reinforcement of cracks, expansion joints, construction joints, and structural joints in various buildings and underground concrete woodwork. [0003] A Chinese patent with the announcement number CN105971301A and the announcement date of September 28, 2016 has been retrieved, which discloses a construction gap grouting device, including a base frame and a rear wall connected to the base frame through a rotating support device. A connected nozzle connection device, wherein the nozzle connection device includes a nozzle rotation driving housing with a sliding clamping cavity, and a nozzle movement driving slider is slidably fitted in the sliding clamping cavity.

AI Technical Summary

Problems solved by technology

[0004] In the gap grouting device for construction in the above cited documents, during the swinging process of the nozzle, the movement of the nozzle drives the slider to slide in the sliding clamping cavity to realize the telescopic swing grouting of the nozzle; however, due to the motion of the nozzle, the slider is driven to Sliding and clamping Sliding in the cavity can only be achieved after the nozzle and the inner wall of the gap are squeezed. During the grouting process of the nozzle, if the nozzle and the inner wall of the gap are kept in contact for a long time, the nozzle will be damaged easily, and the service life of the nozzle is short.
