The utility model discloses a tachometer calibration clamping mechanism, which relates to the tachometer calibration clamping field, and comprises a calibration installation shell, a calibration driving assembly arranged in the calibration installation shell, a calibration clamping assembly arranged on one side of the calibration driving assembly, a clamping driving assembly arranged on one side of the calibration clamping assembly, and a calibration clamping assembly arranged on the other side of the calibration clamping assembly. According to the automobile tachometer calibrating device, the prior art is improved, in actual use, clamping force can be kept in a self-adaptive mode through the calibration clamping assembly, and the problems that in the using process of an existing automobile tachometer calibrating device, a tachometer is fixed at a time, automatic re-clamping cannot be achieved after clamping is loosened, and clamping force cannot be adjusted are solved. The problem that the tachometer is easy to shake in the calibration process due to the fact that the tachometer is damaged, the accuracy of the measurement result is affected, and the practicability of the device is reduced is solved.

The utility model discloses a foundation pile compression resistance static load test platform, which belongs to the technical field of foundation pile compression resistance static load tests, aims at solving the problems that the whole device is inconvenient to move and limit, the installation efficiency of the device is reduced and the stability of the device is inconvenient to maintain, and comprises a support frame, a support frame, a top plate, a U-shaped frame and a balancing weight, stabilizing frames are fixedly connected to the two sides of the top of the top plate, the U-shaped frame is stably arranged on the upper portion of the top plate through the stabilizing frames, the balancing weight is arranged on the U-shaped frame, a connecting device is arranged at the bottom of the U-shaped frame and arranged on the top plate, a foundation pile is arranged below the connecting device, and a movable supporting mechanism is arranged on the supporting frame. By means of the movable supporting mechanism, the whole device can be conveniently moved, meanwhile, the whole device can be stably supported and limited, a stable compression resistance static load test can be conveniently conducted on a foundation pile, the use stability of the device is improved, and meanwhile the installation efficiency of the device is improved through the arrangement of a movable assembly.
