Concrete test block demolding device

Abstract

The invention belongs to the technical field of concrete manufacturing equipment, and particularly relates to a concrete test block demolding device. The device comprises a test mold position, a positioning push-out mechanism and a driving mechanism, wherein the positioning push-out mechanism comprises an upper driving cylinder positioned above concrete test molds and a side driving cylinder positioned on the sides of the concrete test molds; the driving mechanism comprises thrust cylinders with the same quantity with that of concrete test blocks and a thimble assembly which directly applies thrust to the concrete test blocks through the thrust cylinders; the thimble assembly comprises thimbles with the same quantity with that of the thrust cylinders and a connecting plate which is used for connecting the thimbles side by side; needle tips of the thimbles are opposite to round holes at the bottom of the concrete test molds; and the distances from any two needle tips to the concrete test blocks are different. According to the technical scheme of the device, rapid demolding is achieved, the concrete test blocks can be automatically transferred after demolding, the whole demolding process is high in automation degree, and the working efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of concrete manufacturing equipment, and in particular relates to a demoulding device for concrete test blocks. Background technique [0002] Concrete is currently the most widely used civil engineering material, and its physical and mechanical properties are very important, especially for those buildings with concrete as the main material. The mechanical properties of concrete directly affect the safety of these buildings. The physical and mechanical properties of concrete often need to be tested through multiple sets of concrete test blocks. These concrete test blocks have to go through a series of processes such as pouring, demoulding, and curing.

Problems solved by technology

The physical and mechanical properties of concrete often need to be tested through multiple sets of concrete test blocks. These concrete test blocks have to go through a series of processes such as pouring, demoulding, and curing. At present, many concrete molds have inflatable demoulding holes at the bottom, most of which are connected to air guns through high-pressure air pumps to inflate the inflatable demoulding holes, so that the air in the mold expands rapidly to realize the detachment of the concrete test block from the concrete test mold. After that, the concrete test block can be taken out. This method of inflating and demoulding cannot completely get rid of manual operation. It is necessary to manually take out the concrete test block that has been separated from the concrete test mold, and then transfer it to the test block transfer table for the next step of testing. , the whole process of demoulding and transfer is inefficient, time-consuming and laborious. Therefore, there is an urgent need for a set of equipment that can realize the automation of demoulding and transferring test blocks to solve the problem of low demoulding efficiency of traditional concrete test blocks.
