[0032] As shown in Figure 1 and Figure 3 , the driving assembly 4 includes a driving box 41, a first motor 42 and two chains 46. The driving box 41 is fixedly arranged at the top of the support column, and two rotating shafts 44 for supporting and driving the chains 46 are arranged in the driving box 41. Two positioning bearings 45 are arranged on one rotating shaft 44, and two first gears 43 are arranged on the other rotating shaft 44 for driving the chains 46 to move. The first motor 42 is fixedly arranged on the outer wall of the driving box 41, and the output end is in gear engagement with the rotating shaft 44 provided with the first gear 43. The chains 46 are laid on the two rotating shafts 44, are clamped with the positioning bearings 45 on one rotating shaft 44, and are in gear engagement with the first gears 43 on the other rotating shaft 44. One end of the chains 46 is fixedly connected with the lifting arm 12, and the other end is fixedly connected with the counterweight 21, and moves with the rotating of the rotating shaft 44 driven by the first motor 42.
[0033] The driving box 41 is in a cuboid shape and is designed to be hollow up and down to facilitate cooperation and connection with other assemblies. The right end of the driving box 41 is fixedly arranged at the top of the support column and is in communication with the inside. The two rotating shafts 44 are rotatably connected to the driving box 41 through bearing seats at both ends. The two chains 46 are laid on the two rotating shafts 44 and are parallel to each other. The left end rotating shaft 44 is fixedly provided with two positioning bearings 45 for limiting and guiding the two chains 46. The right end rotating shaft 44 is fixedly provided with two first gears 43 for engaging with the two chains 46 to drive and position the chains 46.
[0034] The connection and movement of the chain are described from left to right as follows. The left ends of the two chains 46 are fixed on both sides of the lifting arm 12 to ensure that the lifting arm 12 is uniformly stressed, then extend upward to the rotating shaft 44 at the left end of the drive box 41, and are clamped in the two positioning bearings 45 on the rotating shaft 44, then extend rightward along the length direction of the drive box 41. When the chain 46 slides on the positioning bearing 45, the positioning bearing 45 and the rotating shaft 44 can rotate flexibly, and the rotating shaft 44 can also rotate flexibly in the bearing seat of the drive box 41, reducing the sliding resistance of the chain 46 and the energy consumption of the first motor 42. Two chain boxes are also provided in the drive box 41, which are fixed in the drive box 41 by two fixed rods, on the one hand to reduce the corrosion of the chain 46, and on the other hand to prevent the chain 46 from sagging. After the two chains 46 pass through the chain boxes, they are engaged with the two first gears 43 respectively. The first gear 43 is keyed to the rotating shaft 44, that is, the chain 46 is fixedly connected to the rotating shaft 44 and cannot rotate relative to the rotating shaft 44. After the two chains 46 are engaged with the first gears 43 respectively, they extend vertically downward until they extend into the support column and are fixedly connected to the counterweight 21. In this way, the counterweight 21 and the lifting arm 12 are connected by the chain 46 to form a balanced structure. The first motor 42 is arranged on the outer wall of the drive box 41 and can be on the left side or the right side. The output shaft of the first motor 42 is engaged with the one end gear of the rotating shaft 44 at the right end. The first motor 42 is a reduction motor, which ensures the stable lifting of the lifting arm 12 and protects the chain 46 from breaking due to uneven stress. When the first motor 42 rotates, the rotating shaft 44 engaged with it rotates, and the first gear 43 also rotates synchronously with the rotating shaft 44, thereby driving the chain 46 to move leftward and rightward, and achieving the purpose of driving the chain 46 by the first motor 42 to make the lifting arm box 1 slide up and down on the heavy linear guide rail 51. The left end of the lifting arm 12 is provided with a clamping jaw, thereby achieving the purpose of clamping and taking the material by moving the lifting arm 12 up and down.
[0035] As Figure 3 shown, a second gear 22 is also arranged on the support column 2, and the support seat 3 is provided with a second motor 31 for driving the second gear 22. The support seat 3 rotates with the rotation of the second motor 31.
[0036] A second gear 22 is horizontally sleeved at the bottom of the support column, and a second motor 31 is fixedly arranged on one side of the support seat. The position of the second motor 31 is not particularly limited. The output shaft of the second motor 31 is engaged with the second gear 22. The second motor 31 is a reduction motor, which ensures the stable rotation of the support column on the support seat. According to the carrying requirement, the support column also rotates with the rotation of the second motor 31, thereby increasing the construction area of the lifting arm 12 and making the construction more flexible.
[0037] Working principle: when working, according to the construction requirement, the material is carried, the second motor 31 drives the second gear 22 to rotate to the corresponding position, then the first motor 42 drives the rotating shaft 44 to rotate, then the chain 46 moves left and right under the drive of the first gear 43, then the chain 46 pulls the counterweight 21 to move up and down, when the chain 46 pulls the counterweight 21 to move up, the lifting arm 12 and the lifting arm box 1 slide down on the heavy linear guide rail 51, when the chain 46 pulls the counterweight 21 to move down, the lifting arm 12 and the lifting arm box 1 slide up on the heavy linear guide rail 51, the movement direction of the counterweight 21 is always opposite to that of the lifting arm 12, the clamping jaw on the lifting arm 12 grabs the material along with the lifting arm 12, then the second motor 31 drives the second gear 22 again, the supporting column rotates to the specified position, then the first motor 42 drives the chain 46 to move again, in the same way, the counterweight 21 is pulled by the chain 46 to move down or up, then the lifting arm 12 and the lifting arm box 1 move up or down on the heavy linear guide rail 51, then the clamping jaw on the lifting arm 12 places the material to the specified position, so the material carrying is completed through the reciprocating circulation, after the carrying is completed, the power is turned off and the lifting arm box 1 is returned to the original position.
