Track movable stretchable chute

Abstract

The invention discloses a track movable stretchable chute. The chute comprises a track, a movable support and a stretchable chute. The track is installed along a to-be-poured pipe groove, the movablesupport is installed on the track through a walking wheel, the stretchable chute comprises a plurality of U-shaped grooves which are sleeved and stacked, wherein the sizes of the U-shaped grooves aresequentially decreased, the U-shaped grooves are sequentially sleeved and stacked through cooperation of a sliding groove and a sliding column, wherein the front end of the first U-shaped groove is hinged to the movable support, the rear end of the first U-shaped groove is supported to the movable support through a lifting device, the middle U-shaped grooves and the tail U-shaped grooves are sequentially formed inside the first U-shaped groove, the tail U-shaped grooves are aligned to the to-be-poured pipe groove when stretching out, and the inclined angle of the stretchable chute can be adjusted through a lifting device. The adopted materials are simple and are all commonly-used materials on a construction site, the construction device operation method is simple and easy to control, deepfoundation pit pipeline concrete pouring can be easily, conveniently, rapidly and accurately performed, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring, and relates to a chute for concrete pouring, in particular to a rail-moving telescopic chute. Background technique [0002] In the construction of municipal roads, the construction of rain and sewage pipelines is indispensable, but for the construction of main pipelines, there are often large diameters of pipelines, deep excavation depths, and large excavation widths of pipe grooves, which brings difficulties to concrete pouring. Traditional There are three methods for concrete pouring of rainwater and sewage pipelines in deep foundation pits, one is to use concrete pump trucks to pour concrete, and using this method to pour concrete for pipelines requires a large space for erecting concrete pump trucks, and the left side of the pipeline after excavation The space is limited, and static and dynamic loads are not allowed within a certain distance from the edge of the foundation pit, while...
