The invention discloses a brick-moving device for construction, which relates to the technical field of brick transportation. It solves the problem that when a slide plate loaded with slope protection bricks slides down from a base, a large inertia is generated due to gravity. Therefore, when the slide plate moves to the lowermost end of the base, the impact force on the end of the base is large, which not only easily causes damage to the device, but also poses a safety hazard to the surrounding installation workers. The device comprises a base plate installed on a lifting support, a support seat is fixedly installed on the upper end of the base, and the support seat is located at the left end of the base, and two symmetrically distributed sliding rods are fixedly embedded on the right end of the support seat, and a positioning seat is fixedly connected to the right end of the sliding rod, and the positioning seat is fixedly connected to the base plate. The invention installs a brick-moving mechanism, which is not only conducive to transporting the slope protection bricks according to the installation position of the workers, but also the conveying plate moves slowly, and no collision will be generated due to inertia during the transportation process, and there is no safety hazard during use.

The utility model discloses an intelligent sorting device which comprises a containing disc, the outer side of the containing disc is fixedly connected with three first fixing plates, the sides, away from the containing disc, of the three first fixing plates are fixedly connected with an air cylinder, and the output end of the air cylinder is fixedly connected with a U-shaped block. Compared with a traditional device, the device is provided with an air cylinder, a U-shaped block, a containing box, a baffle, a first limiting rod, a first spring, a second limiting rod, a second fixing plate, a second spring, a third fixing plate, a second limiting telescopic rod, a fourth fixing plate, a third spring and a steel wire rope; according to the storage box, when moving of articles in the storage box is stopped suddenly, the articles can be protected and the inertia acting force of the articles can be reduced through the damping mechanisms in the baffles, so that the articles are prevented from being damaged, and the personal safety of workers is guaranteed.

This invention belongs to the field of lifting mast technology, specifically relating to a precision rotation mechanism and method for a vehicle-mounted wheeled lifting mast. It includes a wheeled chassis assembly and a mast lifting mechanism mounted at its top center via an adjustment mechanism. The mast lifting mechanism is rotatably connected to the wheeled chassis assembly. A mast assembly is mounted on the mast lifting mechanism, and an operating platform is mounted on the mast assembly. The adjustment mechanism includes a rotation component for rotating the mast lifting mechanism and a drive component for driving the rotation component. The drive component includes a support plate. This invention effectively slows down the turning speed of the mast lifting mechanism through the adjustment mechanism, thereby achieving more precise positioning and position adjustment. This is crucial for tasks requiring high-precision positioning, such as measurement, imaging, and positioning work. Furthermore, it reduces the influence of inertial forces and motion instability, meeting the requirements of high precision and high controllability.
