The utility model discloses a rock drill test bench capable of sensing distance by a stay cord, which comprises a test bench, a grid plate is fixedly mounted on the upper surface of the test bench through screws, a grating is mounted on the surface of the grid plate, a mounting platform is mounted above the test bench in a sliding manner, a positioning seat is fixedly mounted on the left side of the test bench, and the positioning seat is fixedly mounted on the right side of the test bench. An anti-collision rubber seat is fixedly mounted on the surface of the positioning seat; when the installation platform moves forwards by one grating plate, the gratings on the grating plates can sense the grating, the distances between the gratings are the same, the gratings can be marked and sensed when passing through one group of gratings, the movement distance can be conveniently calculated, the pull rope is pulled, the intuition is higher, and meanwhile, by matching with the sensing of the gratings, the accuracy is higher. Real-time distance sensing of the installation platform in a continuous motion state is facilitated, after the test is finished, elastic potential energy stored in a coil spring in the coil spring disc is released, and the installation platform is pulled back to the initial test end.

A mechanical arm designed to provide automated garbage collection with smooth, constant movement (i.e. movement that has minimal jerk / shock) thereby resulting in limited shock stress on the components and leading to high durability. The mechanical arm including a horizontal displacement system having a plurality of sections rollingly engaged to one another and a motor mounted to an immobile section for drivingly extending section in a generally horizontal orientation, a vertical displacement system having a plurality of masts rollingly engaged to one another and a motor mounted to a first mast for drivingly extending a second mast in a generally vertical orientation, and / or a grabber system having a plurality of fingers mounted to a frame and operated by a single motor.
