Problems solved by technology

Because the length of the sling is fixed, one end is hung on the hook, and the other end moves in an arc-shaped path, so when the worker pulls the object to the target plane, he needs to overcome the gravity of the object and lift the object a certain distance, which is laborious

Embodiment 1

[0030] The electric elevator includes a frame 1, a transmission shaft 6 located on the top of the frame 1, and the frame 1 on both sides of the length direction of the transmission shaft 6 is slidably connected with a lifting platform 2 and a counterweight box 4.

[0031] The two ends of the transmission shaft 6 in the longitudinal direction are rotatably connected to the frame 1, and two lifting sprockets 62 protrude from the transmission shaft 6. A chain (not shown in the figure) is fitted on the lifting sprocket 62, and the chain goes around the top of the lifting sprocket 62, and both ends of the chain are fixed on the counterweight box 4 and the lifting platform 2 respectively.

[0032] The top of the frame 1 is also provided with a lifting motor 7, the output section of the lifting motor 7 is provided with an output sprocket 71, a transmission sprocket 61 is provided on the transmission shaft 6 opposite to the output sprocket 71, the transmission sprocket and the output sprock...

Embodiment 2

[0041] An elevator. The difference from Embodiment 1 is that both ends of the drum 242 are equipped with sprockets, and the sprockets are connected by a chain. One end of the chain is connected to the sprocket, and the other end is connected to the output end of the servo motor or stepping motor. PLC control. In this way, the motor outputs power at a certain speed according to the program instructions stored in the PLC, thereby driving the object on the drum 242 to move.

[0042] When loading an object, the object is driven by the roller 242 to move from the open end into the loading frame 24 until it hits the loading frame 24. At this time, the roller 242 rotates and the object is blocked by the loading frame 24 and stops moving, thereby realizing automatic transportation of the object To the loading frame 24.

[0043] When loading, place the objects to be transported in sequence along the width of the opening, and the objects can be automatically shipped and placed neatly. The ...

Abstract

The invention discloses a lifter and relates to the field of carrying lifting mechanical equipment. The lifter comprises a rack, a lifting platform slidably connected to the rack, a transmission mechanism controlling the lifting platform to slide vertically and a lifting motor providing power for the transmission mechanism. At least two parallel rollers are arranged on the lifting platform. The rollers are used for supporting an object to be hoisted. The lifting platform comprises bases and suspension arms. The bases are slidably connected to the rack. The rollers are arranged on the suspension arms. A carrying frame is arranged on the suspension arms. The carrying frame is a rectangular frame. One end of the carrying frame is an opening end for loading and unloading the object. By using the lifter, when the object is transported to a target plane height, a worker can save more effort when taking down the object.

Description

Technical field [0001] The invention relates to the field of load-carrying lifting machinery and equipment, in particular to an elevator. Background technique [0002] The Chinese invention patent with publication number CN104114474A discloses an elevator. Including motors, rollers, ropes and transmission mechanisms. One end of the rope is fixed on the roller shaft, and the other end goes around the transmission mechanism and is provided with a hook. [0003] The motor drives the roller to rotate, so that the roller rewinds or unwinds the rope, so that the hook at the other end of the rope moves closer to or away from the ground, thereby driving the object on the hook to move up and down. [0004] However, when the hook is used to carry the object to different horizontal planes, since the object and the hook are usually connected by a sling, one end of the sling fixes the object and the other end is hung on the hook. Due to the gravity of the object, the sling is in a vertical sta...
