[0004] However, the above-mentioned equipment still has some shortcomings in use. The storage space of the lifting equipment is fixed. When it is necessary to transport materials of different quantities or volumes, if the material volume is large or the quantity is large, the fixed-space storage box often cannot meet the needs, resulting in low transportation efficiency. It may also be necessary to frequently repackage or transfer the materials, which increases the operation process and cost. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a stable lifting device that solves the problem that the storage space of some existing lifting devices is usually fixed. When transporting materials of different quantities or volumes, if the materials are large or numerous, fixed-space storage boxes often cannot meet the needs, resulting in low transportation efficiency. Furthermore, frequent repackaging or transfer of materials may be necessary, increasing operational procedures and costs.

[0006] This utility model provides the following technical solution: a stable lifting device, including a base plate, two vertical rods fixedly connected to the upper surface of the base plate, a top plate fixedly connected between the top ends of the two vertical rods, a winding roller rotatably mounted on the upper surface of the top plate, a steel wire rope wound around the surface of the winding roller, and a storage box fixedly mounted at the bottom end of the steel wire rope.

[0007] The storage box has a hollow bottom plate and two side plates. Two extension frames are slidably arranged in the hollow part of the storage box. A set of fixing plates is fixedly connected between the inner top wall and bottom wall of the storage box bottom plate. A bidirectional screw is rotatably connected between the two fixing plates. The two ends of the bidirectional screw extend to the outside of the connected fixing plates respectively. The surfaces of the two extension frames are provided with threaded holes. The two extension frames are threadedly installed at the two ends of the bidirectional screw through the threaded holes.

[0008] Preferred technical solution 1: A first motor is fixedly connected to the upper surface of the top plate, and the output end of the first motor is fixedly connected to the winding roller. A through hole is opened on the upper surface of the top plate, and the wire rope can move up and down inside the through hole.

[0009] Preferred technical solution 2: A second motor is fixedly connected to the lower surface of the storage box, the output end of the second motor extends into the bottom plate of the storage box and is fixedly connected to a first bevel gear, and a second bevel gear is fixedly sleeved on the surface of the bidirectional screw, and the first bevel gear and the second bevel gear mesh with each other.

[0010] Preferred technical solution 3: A set of limiting rods is fixedly connected to the surface of each of the two fixed plates, and a set of limiting grooves is opened on the surface of each of the two extension frames. The two extension frames are slidably sleeved on the two sets of limiting rods through the limiting grooves.

[0011] Preferred technical solution four: Limiting sleeves are slidably fitted on the surfaces of both vertical rods, and both limiting sleeves are fixedly connected to the storage box.

[0012] Preferred technical solution five: each of the two extension frames is provided with a movable door, and each of the two movable doors is provided with a door lock.

[0013] Compared with the prior art, this utility model provides a stable lifting device with the following advantages: In use, the materials or tools to be lifted are placed inside the storage box. Then, the rotation of the first motor drives the winding roller to rotate, thereby winding the wire rope and lifting the storage box and materials to the specified height. When the internal space of the storage box is insufficient to hold materials or tools, the rotation of the second motor drives the first and second bevel gears to rotate, which in turn drives the bidirectional screw. The rotation of the bidirectional screw causes two extension frames to extend from both sides of the storage box, thus expanding the internal space of the storage box and allowing for the placement of more materials and tools. This device can quickly lift materials and tools to the specified position, and the internal opening of the storage box can be adjusted to accommodate materials of different quantities and volumes, making it convenient to use.
