Embodiment 1
[0031] combine figure 1 with image 3 , a balance crane in this embodiment that facilitates the removal of lifting nuts, and is suitable for working conditions where the load is not greater than 500KG. It includes a transmission box 11, a top cover 12, a counterweight 2, a connecting plate, a parallelogram bar 4, a motor 51, a screw 52, a lifting nut 53, a connecting shaft 54 and a column 8. The column 8 is used to support the transmission box 11, the top of the transmission box 11 is provided with a top cover 12, the top cover 12 is fixed on the transmission box 11 by screws, when the lifting nut 53 needs to be disassembled, the top cover 12 can be removed quickly Next, remove the restriction of the top cover 12 to the removal of the lifting nut 53.
[0032] The left and right sides of the transmission box 11 are respectively provided with a first guide groove 111 and a second guide groove 112. Compared with the traditional structural design of uniformly opening vertica...

The invention discloses a balance crane capable of conveniently disassembling a lifting nut and a lifting nut disassembling method, and belongs to the technical field of balance cranes. The balance crane comprises a transmission case, a top cover, a connecting plate, a screw rod, a lifting nut and a connecting shaft, wherein the top of the transmission case is movably connected with the top cover; two sides of the transmission case are respectively provided with a first guide groove and a second guide groove; the screw rod penetrates through the transmission case, and the screw rod is provided with the lifting nut in a sleeved manner; the left side and right side of the lifting nut are respectively connected with the connecting shaft, and the connecting shaft penetrates through the connecting plate and is respectively inserted into the first guide groove and the second guide groove; the connecting plate comprises a lower connecting plate and an upper connecting plate; and the lower connecting plate and the upper connecting plate are buckled with the connecting shaft, and the lower connecting plate and the upper connecting plate are movably connected. The balance crane disclosed by the invention is not influenced in transmission efficiency by adopting a mode of dividing the connecting plate, and achieves great convenience for the replacement of the lifting nut through optimized structural design, thus improving the working efficiency of the balance crane.
Description
technical field [0001] The invention relates to the technical field of balance cranes, and more specifically, relates to a balance crane for easy disassembly of lifting nuts. Background technique [0002] The balance crane is a kind of material lifting equipment, which uses a unique spiral lifting mechanism to lift heavy objects. Balance cranes mainly include electric balance cranes, pneumatic balance cranes and hydraulic balance cranes. Among them, electric balance cranes are more commonly used. They use motors to drive screw rods to lift goods. They are mainly used for lifting workpieces in workshops or moving objects in local spaces. , has the characteristics of flexibility, portability and low cost. [0003] At present, the common electric balance cranes on the market are assembled by welding for many parts, which ensures the reliability of the assembly between parts. However, since the electric balance crane relies on the screw nut rotation mechanism to complete the u...
