However, the structure cannot adjust the size of the placement structure according to the size of the material to be tested, and the position where the workpiece to be tested is placed is too close to the test position, which poses a high safety hazard to the operator. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a fully automatic concrete workability detection device, which solves the current problems of being unable to adjust the placement size according to the test material and the existence of safety hazards.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fully automatic concrete working degree detection device, comprising a device body, a first motor, a hydraulic testing machine and a control panel, wherein the first motor is arranged at the upper end of the device body, the hydraulic testing machine is arranged at the upper end of the same side of the device body, and the control panel is arranged at the rear end of the device body;

[0016] Compared with the prior art, the present utility model provides a full-automatic concrete workability detection device, which has the following beneficial effects:

[0017] The fully automatic concrete workability detection device is provided with a support arm, a clamping block, a shaft column, as well as gears and racks. When the device tests the concrete, the operator controls the first motor, the second motor and the hydraulic testing machine through the control panel. First, the operator starts the first motor, and the first motor drives the shaft column to rotate the support arm to the outer end of the device main body. Then, the operator places the concrete to be tested between the support arm and the clamping block. At this time, the operator controls the second motor to start. The second motor drives the gear, and the gear drives the other gear through the shaft body in the middle. When the two gears rotate, they drive the rack meshing with the lower end to move. When the rack moves towards the inner side of the support arm, it will pull the clamping block connected to the end and shorten the distance between the clamping block and the support arm until the concrete test piece is clamped by the clamping block and the support arm. At this time, the first motor drives the shaft column to rotate in the reverse direction until the position of the concrete test piece is at the upper end of the pressure-bearing platform. Then, the operator controls the hydraulic testing machine to apply pressure to the concrete, so as to detect the force data of the concrete. After the test is completed, the operator controls the first motor to drive the shaft column to rotate the support arm to the outside of the device main body and take out the concrete test piece; through the above settings and processes, the device can not only greatly improve the automation degree of concrete testing, but also adapt to test workpieces of different sizes by adjusting the distance between the clamping block and the support arm. Through the cooperation of the shaft column and the support arm, the distance between the placement position and the hydraulic testing position of the concrete test piece can also be increased, so that the operator does not need to approach the hydraulic testing equipment whether placing or taking out the concrete test piece, improving the operation safety of the operator.
