Lifting device for non-abrasive or slightly abrasive materials

Abstract

The present invention discloses a lifting device for non-abrasive or low-abrasive materials, wherein a winch retracts and extends a traction rope, thereby causing a carrier plate at the other end of the traction rope to move vertically up and down on a support frame, thereby lifting and transporting the materials. When the winch lowers the carrier plate onto the base, a positioning plate can be movably accommodated in a receiving groove, so that the joint plate is movably supported on the positioning plate. The elastic support force of the joint plate is utilized to prevent the carrier plate from directly colliding or hitting the base, thereby reducing vibration of the carrier plate under the action of the elastic support force of the joint plate, thereby preventing the material on the carrier plate from spilling. After the carrier plate is lowered to a low position, the unloading plate is unlocked by a locking structure, and the unloading plate is pulled out of the notch of the carrier plate to load and unload the materials piled on the unloading plate. The present invention solves the problem that when the existing lifting platform is lowered to the support seat at the bottom, it is easy to collide with the support seat, causing the powdered material on the lifting platform to spill.

One end of a traction rope is connected to the winch drum. The middle of the traction rope is wound around the diverting pulley. The other end of the traction rope is connected to the loading plate 2.

[0036] The present invention is a lifting device for non-abrasive or low-abrasive materials, wherein the winch retracts and extends the traction rope, thereby causing the carrier plate at the other end of the traction rope to move vertically up and down on the support frame, thereby lifting and transporting the materials. When the winch lowers the carrier plate onto the base, the positioning plate can be movably accommodated in the receiving groove, so that the joint plate is movably supported on the positioning plate. The elastic support force of the joint plate is used to prevent the carrier plate from directly colliding or hitting the base, and the vibration of the carrier plate is reduced by the elastic support force of the joint plate, thereby preventing the material on the carrier plate from spilling. On the other hand, after the carrier plate is lowered to a low position, the unloading plate is unlocked by the locking structure, and the unloading plate is pulled out from the notch of the carrier plate to load and unload the materials piled on the unloading plate, thereby improving the material loading and unloading efficiency and thus improving the construction efficiency.
