Compaction test apparatus

Abstract

The invention discloses a compaction test apparatus. The key point of the technical scheme thereof is characterized in that the compaction test apparatus comprises a machine frame, a workbench, a sample mold and a fixing mechanism; the fixing mechanism comprises positioning rods, a positioning frame and a driving mechanism; at least two positioning rods are arranged on the fixing mechanism; the positioning frame is simultaneously slidably connected with all of the positioning rods; the driving mechanism comprises a support cylinder, a triggering rod and a transmission mechanism; the support cylinder sleeves the positioning rods; the triggering rod passes through the interior of the workbench; the transmission mechanism corresponds to the positioning rods one by one; the transmission mechanism comprises a transmission gear, a first gear rotatably connected to the interior of the workbench, and a rack passing through the workbench, in a using process, the sample mold only needs to be placed on the triggering rod, the triggering rod is enabled to be moved to the interior of the workbench, and the triggering rod pushes the positioning frame to be upwards moved through the transmissionmechanism. So the support frame does not need to be adjusted manually, the efficiency is higher. While a sample is detected, a compaction hammer on the compaction test apparatus does not contact withthe positioning frame, and the detection is more accurate.

Description

technical field [0001] The invention relates to the technical field of building detection equipment, in particular to a compaction instrument. Background technique [0002] The compaction instrument is a kind of construction equipment, which is mainly used to determine the optimum moisture content and unit volume weight of compacted soil. [0003] At present, the Chinese patent whose notification number is CN204789091U discloses a Marshall sample electric compactor, which includes a frame and a sample mold fixing mechanism, a workbench is arranged on the frame, and a sample mold is placed on the workbench. The sample mold fixing mechanism includes a sample mold positioning frame and a sample mold positioning rod vertically arranged on the workbench. The sample mold positioning frame includes a sample mold positioning frame for positioning and matching with the upper end of the sample mold and symmetrical fixing The guide plates are arranged on both sides of the sample mold ...

Problems solved by technology

However, in the process of the user manually rotating the support cylinder, it is difficult to ensure that the two support cylinders rotate synchronously, that is to say, the movement of the sample mold support frame will be stuck, which will increase the time for moving and adjusting the sample mold support frame , which reduces the efficiency of the compaction instrument to a certain extent
