[0002] Balance crane is a new type of material lifting equipment and a mechanical equipment that replaces human labor to reduce labor intensity. The basic classification of balance cranes can be roughly divided into three categories. The first is a mechanical balance crane, which is the most common type of balance crane, that is, it uses a motor to drive the screw rod to rise to lift the goods; the second is a pneumatic balance crane, which mainly uses an air source to suck up the goods to achieve lifting. The third is a hydraulic balance crane, which is generally used to lift heavier goods.

[0003] During use, the existing balancing crane usually needs to be driven by a manual operation controller so that the balancing crane can move the materials from the placement location to the processing location. During the movement, the balancing crane needs to rotate within a certain range. However, in the actual operation, it is difficult for the operator to accurately grasp the rotation range, which is not conducive to the accurate transfer of materials and increases the safety hazards of use. In this regard, this scheme specially proposes a traction-type limit sensor-equipped intelligent balancing crane to solve the above problems. Utility Model Content

[0024] Embodiment: According to the embodiment of the utility model, a traction-type limit sensor-equipped intelligent balancing crane includes a base plate 1, a base frame 2, a rotating plate 3 and a traction frame 4. A rotating column 22 is fixedly installed between the central movable parts of the bearing seat 21, so that the rotating column can rotate stably. The structure is simple and stable. A worm gear 23 is fixedly installed on the rotating column 22 in the base frame 2. A servo motor 24 is fixedly installed at one end of the inner part of the base frame 2. A worm 25 meshingly connected with the worm gear 23 is fixedly installed at the output end of the servo motor 24. The servo motor drives the worm gear and the worm gear 23. The rod performs meshing rotational motion, and the structure is simple and stable. A support rod 5 is fixedly installed on one side of the bottom of the worm gear 23, and a limit plate 51 is fixedly installed at the center of the inner bottom end of the base frame 2. The limit plate 51 is provided with an annular groove 52. An arc-shaped slider 53 that matches the annular groove 52 is fixedly installed at the bottom end of the support rod 5, so that the arc-shaped slider rotates stably and realizes limiting activity. A first positioning block 54 is fixedly installed at one end of the annular groove 52, and a second positioning block 55 is fixedly installed at the other end of the annular groove 52. The purpose of limiting is achieved by using two positioning blocks.

[0025] refer to Figure 1 and Figure 2 One end of the traction frame 4 is movably connected to a traction arm 43 through a U-shaped groove 41, and a driving motor 42 is fixedly installed on the traction frame 4 on one side of the U-shaped groove 41 to achieve a traction effect.

Electric shock sheets 56 are fixedly installed at both ends of the arc-shaped slider 53 by screws. The first positioning block 54 and the second positioning block 55 are both conductive. Once they are offset to achieve electrical connection, the drive control module suspends the operation of the motor. The electric shock sheet is electrically connected to the first positioning block 54, the second positioning block 55 and the drive control module 57 to achieve the purpose of limit sensing.

[0027] When in use, the balancing crane is towed by the traction frame, the traction arm and the driving motor. The structure is simple and stable. The servo motor drives the worm to rotate the worm wheel on the rotating column. During the rotation, the worm wheel drives the rotating plate on the rotating column to perform stable rotational movement through the bearing seat. During the rotation, the worm wheel drives the arc-shaped sliding block under the support rod to rotate on the limit plate. The support rod will drive the electric shock sheet on the arc-shaped sliding block to rotate between the first positioning block and the second positioning block.
