The utility model discloses an intelligent test device used for detecting keel mechanical properties, which comprises a test frame, a plurality of suspension assemblies, a loading mechanism and a displacement measurement assembly, the test frame comprises a main beam and side beams, the suspension assemblies are installed on the main beam, each suspension assembly comprises a suspension rod used for suspending a keel, and the loading mechanism is installed on the suspension rod. The loading mechanism is of a movable portal frame structure and can be arranged above the test frame in a crossing mode, a lead screw is installed on a cross beam of the loading mechanism and connected with a first motor, the first motor is connected with a controller, the lead screw is connected with a moving block, a second motor is installed on the moving block, and the second motor is connected with a second motor. The second motor is connected with an automatic release hook through a rope, and a weight or a sand bag is hung on the automatic release hook. According to the utility model, the test requirements of keels of various sizes can be met, and the safety of the test process can be improved while the test efficiency is improved.

This utility model discloses an automated testing device for adhesive products, including a base and a U-shaped groove fixed on the base. A roll of adhesive tape is rotatably mounted on the U-shaped groove and fixed by a buckle. The roll of adhesive tape is connected to the adhesive tape. The U-shaped groove is equipped with a fastening component and a measuring component. The fastening component includes a movable pressure roller and a drive mechanism to compact the adhesive tape. The measuring component includes a connecting plate, a stretching machine, and a pneumatic clamp, which can test the adhesive tape. The drive mechanism consists of a cylinder, a slide rail, and a limit slider, which drives the movable pressure roller to move. The measuring component drives the stretching machine to slide through a motor and a lead screw, adjusting the stretching angle. The U-shaped groove is made of stainless steel, and the stretching machine has a pneumatic system to drive the pneumatic clamp. This device has a high degree of automation, accurate testing, and strong applicability.

This utility model belongs to the field of road engineering testing, and specifically discloses a mold for forming rutted specimens. It includes a main body of the mold formed by a base plate and several first side plates connected together; at least some of the first side plates are connected to the base plate by a single-degree-of-freedom rotational method; it also includes a fixing frame formed by several second side plates sequentially fixedly connected and enclosing each other; each first side plate corresponds to a second side plate and is joined vertically by a butt joint structure, forming a cubic cavity structure with an open top after joining; a push plate is embedded in the base plate, and the push plate is connected to a drive plate placed outside the main body of the mold and driven by the drive plate to generate an upward pushing force on the specimen in the main body of the mold. This utility model facilitates the assembly, disassembly, and demolding of the mold.
