Storage crane based on parallelogram mechanism

Abstract

The invention discloses a storage crane based on a parallelogram mechanism. A vehicle frame is a bracket of an n shape of which the opening faces right; a parallelogram lifting and lowering mechanismis installed on the middle of the bracket of the n shape of which the opening faces right; a driving controller drives a lifting and lowering driving mechanism to drive the parallelogram lifting and lowering mechanism to carry out pitching deformation movement; a clamping and grasping mechanism is hinged to the front end of the parallelogram lifting and lowering mechanism so as to carry out corresponding lifting and lowering movement along with the pitching movement of the lifting and lowering mechanism, and the clamping and grasping mechanism keeps a horizontal state; the driving controller controls the clamping and grasping mechanism to grasp and release an article; a movement mechanism is installed on the bottom of the vehicle frame; and the driving controller drives the movement mechanism to drive the vehicle frame to move and steer. The storage crane moves and rotates through the movement mechanism; through the positive and negative rotation movement of a gripper motor, a left clamping jaw and a right clamping jaw are driven to clamp the article in a face-to-face way or loosen the article in an opposite direction; through the positive and negative rotation movement of a lead screw motor, the parallelogram lifting and lowering mechanism is driven to carry out pitching movement, and the clamping and grasping mechanism is driven to synchronously lower and lift to grasp and release articles at different heights. A whole operation is controlled by the driving controller, and electrified control is realized so as to be efficient and save labor.

Description

technical field [0001] The invention belongs to the technical field of cranes, in particular to a storage crane based on a parallelogram mechanism. Background technique [0002] With the improvement of people's living standards and work needs, more and more people choose to settle in cities, but limited by economic conditions, many people can only buy small-sized houses. For small-sized houses, in order to store more daily items to the maximum, people usually choose to use multi-grid vertical lockers, but the multi-grid vertical lockers have items in the higher panes during use. Not easy to pick and place. Some existing cranes can pick and place items at different heights, but these cranes have complex structures, many drive control mechanisms, high cost, inconvenient operation, and the gripping mechanism is complex and heavy, unstable, and large in size, relatively It takes up space and is not suitable for small-sized users. Contents of the invention [0003] Aiming at...
