Description
Technical Field
[0001] The utility model relates to the technical field of loading and unloading hooks, in particular to a heavy block hook capable of realizing automatic loading and unloading. Background Art
[0002] Among the existing gravitational potential energy power generation technologies, there is a technology that uses a ring-shaped conveyor belt to transport the weight up and down, and stores energy by raising and lowering the height. During the transportation process, the weight needs to be loaded and unloaded by a hook. However, the existing loading and unloading hooks have the following problems during the transportation process:
[0003] (1) There is wind at high altitudes. The surface area of the weight is large. When subjected to strong wind, the hook cannot effectively unload the force and is prone to bending, causing the weight to fall.
[0004] (2) Loading and unloading operations are inconvenient and positioning cannot be performed quickly. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a heavy block hook capable of automatically loading and unloading materials, thereby solving the above-mentioned problems.
[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a weight hook capable of automatically loading and unloading materials, comprising a connecting rod conveyed by an endless conveyor belt, the bottom end of the connecting rod is rotatably connected to a rotating rod that rotates itself, the bottom end of the rotating rod is rotatably connected to a hook for loading the weight, and also comprises a direction-changing component for guiding the hook and a position-limiting component for limiting the hook;
[0007] The surface of the rotating rod is fixedly connected with a gear, and the direction-changing assembly includes a driving gear arranged under the endless conveyor belt and driven by a motor;
[0008] The limiting assembly includes a driving cylinder fixed under the endless conveyor belt, the piston rod of the driving cylinder is fixedly connected to a rotating cylinder, one end of the piston rod of the rotating cylinder is fixedly connected to a limiting rod, and when in use, the connecting rod is transported by the endless conveyor belt to drive the hook to be transported, and when it is transported to the loading position, the weight block is positioned and placed behind the guide assembly and the limiting assembly, and then the hook is transported to the guide assembly, at which time the active gear is engaged with the gear, and the gear is driven to rotate by the rotation of the active gear, which drives the rotating rod to rotate and adjust the angle of the hook so that the tip of its L-shape is aligned with the connecting piece of the weight block, and then the hook continues to move forward and is inserted into the connecting piece of the weight block, at which time the rotating cylinder drives the limiting rod to rotate and press against the rear of the hook, and when the hook moves forward When the gear is in motion, the weight block is hooked up. At this time, the limit rod and the side limit sleeve play the role of rear support, keeping the hook in a horizontal state, so that the weight block can be loaded effectively. When unloading, the weight block is transported to a certain position, and the driving gear is meshed with the gear when it is about to reach the unloading position. The rotation of the driving gear drives the gear to rotate, and drives the rotating rod to rotate and adjust the angle of the hook so that the tip of the L-shape is aligned with the left side. Then the weight block falls on the slope. At this time, the hook is forced to move to the left, preventing the weight block from being unhooked. At this time, the rotating cylinder is started to drive the limit rod to rotate and resist the left side of the hook, limiting it to prevent it from rotating to the left with the weight block, quickly unloading, and then continuing to convey, the weight block is lifted in a cycle to store energy.
[0009] As a further solution of the utility model: a side limit sleeve is fixedly connected to one side of the rotating rod, and an embedded groove adapted to the surface of the hook is opened at the bottom of the side limit sleeve. The side of the hook is limited by the setting of the side limit sleeve to prevent the hook from rotating and causing an inclination angle due to wind during high-altitude transportation, causing the weight to fall off.
[0010] As a further solution of the utility model: a connecting piece which is engaged with the hook is provided on the top of the weight block.
[0011] As a further solution of the utility model: the hook is L-shaped.
[0012] As a further solution of the utility model: two groups of direction-changing components and two groups of position-limiting components are respectively arranged at the loading and unloading locations of the weight block.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The utility model hooks up the weight block when the hook moves forward. At this time, the limit rod and the side limit sleeve play the role of rear support, keeping the hook in a horizontal state, so that the weight block can be effectively loaded. When unloading, the angle of the hook is adjusted to make the tip of the L-shape align with the left side, and then the weight block falls on the slope. At this time, the hook is forced to move to the left, preventing the weight block from being unhooked. At this time, the rotating cylinder is started to drive the limit rod to rotate and resist the left side of the hook, limiting it to prevent it from rotating to the left with the weight block, quickly unloading, and then continuing to convey, the weight block is lifted cyclically to store energy.
[0015] 2. The utility model limits the side of the hook by setting the side limit sleeve to prevent the hook from rotating and tilting due to wind during high-altitude transportation, which may cause the weight to fall off. BRIEF DESCRIPTION OF THE DRAWINGS
