Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 with figure 2 , a full-automatic Marshall compaction instrument, including a workbench 1, an oven 2 and two compaction instrument bodies 3 are arranged on the upper surface of the workbench 1 in turn, and the oven 2 is used to carry out the compression ring, the mold cylinder and the mold base heating. An installation frame 4 located between two compaction instrument bodies 3 is fixedly connected to the upper end surface of the workbench 1 , and a gantry frame 5 with an open lower end is horizontally slidably connected to the installation frame 4 .

[0042] refer to figure 2 with image 3 , Between the inner walls on both sides of the gantry frame 5, a pressing ring grabbing mechanism 6, a mold cylinder grabbing mechanism 7 and a mold base grabbing mechanism 8 are sequentially arranged from top to bottom.

[0043] refer to fi...

Abstract

The present invention discloses a full-automatic Marshall compactor which comprises a workbench and two compactor bodies, a mounting frame is arranged on the workbench, a portal frame is horizontally arranged on the mounting frame in a sliding mode, and a pressing ring grabbing mechanism, a die cylinder grabbing mechanism and a die base grabbing mechanism are arranged on the portal frame; the die cylinder grabbing mechanism comprises two supporting plates horizontally arranged on the portal frame in a sliding mode, supporting blocks vertically arranged on the supporting plates in a sliding mode and abutting columns horizontally arranged on the supporting blocks in a rotating mode, and a driving mechanism for driving the abutting columns to rotate is arranged on the mounting frame. The two compaction apparatus main bodies are used for hammering the surfaces of the two sides of a test material in sequence, when the pressing ring, the mold cylinder and the mold base move from one compaction apparatus main body to the other compaction apparatus main body, the pressing ring grabbing mechanism controls the pressing ring to be separated from the mold cylinder, the mold cylinder grabbing mechanism controls the mold cylinder to be separated from the mold base and turns over the mold cylinder by 180 degrees, and therefore, the automatic overturning of the die cylinder is realized, and the workload of testers is reduced.

Description

technical field [0001] The invention relates to the field of Marshall compaction instruments, in particular to a full-automatic Marshall compaction instrument. Background technique [0002] The Marshall compaction tester is a special instrument for sample formation in the Marshall stability test of asphalt mixture. Its structure and performance fully meet the requirements of road test regulations. The instrument has the advantages of small size, convenient operation, reliable operation, automatic compaction and automatic shutdown. [0003] Chinese patent CN211061284U discloses a Marshall compaction instrument, which includes a frame, a compaction hammer guide rod arranged on the frame for longitudinal sliding guidance, a compaction hammer provided for longitudinal sliding guidance on the compaction hammer guide rod, As well as the sample mold arranged under the compacting hammer, the top of the frame is connected with a horizontally arranged rotating shaft through the suppo...
