Description

Technical Field

[0001] The utility model belongs to the technical field of highway engineering, and in particular relates to a highway engineering compression test device. Background Art

[0002] In order to ensure the normal use of highway projects, the strength of concrete determines the quality of the completed highway projects. After the completion of the highway projects, the concrete needs to be subjected to a compression test. When conducting the compression test, a compression test device is required. The concrete block is squeezed downward by the pressing mechanism, and the pressure data is collected by the pressure sensor, and the pressure data is sent back to the compression test host for display. When the pressing mechanism squeezes the concrete block downward, a large amount of dust and solid waste will be generated, which has the disadvantages of large dust pollution and inconvenient cleaning of solid waste.

[0003] In order to solve the above technical problems, a Chinese patent document with authorization announcement number CN216560075U discloses a highway engineering compression test device, which absorbs the smoke generated when the concrete is squeezed by setting a purification component to effectively reduce the dust pollution generated during the experiment, and cleans the solid waste generated after the experiment through the material collection component. The frame is in direct contact with the ground, which is not conducive to moving the position of the highway engineering compression test device. In order to facilitate the transfer of the highway engineering compression test device, there are usually the following technical improvement paths:

[0004] First, fixed casters are installed at the bottom of the frame. Since the downward pressure mechanism exerts a large force to squeeze the concrete block downward, the fixed casters are easily damaged.

[0005] Second, foldable casters are installed at the bottom of the frame. When the compression test is carried out, the casters are in a folded state to avoid damage caused by direct force on the casters. When the highway engineering compression test device needs to be transferred, the casters are in an unfolded state to facilitate the movement of the highway engineering compression test device. Although the above scheme can avoid direct force on the casters during the compression test. However, the overall mass of the highway engineering compression test device is relatively large, and the folding and unfolding operations of the casters require the collaborative work of multiple personnel, which has the disadvantage of inconvenient operation.
