[0020] Beneficial effects of the present invention:

[0021] (1) In the present invention, during hoisting, the electric equipment can be hoisted by the hoisting hook through the rotation of the first rope reel. At the same time, the movement of the adjusting roller can be controlled by the extension and contraction of the sliding cylinder, so that the distance between the two symmetrically arranged adjusting rollers can be controlled, and the position of the fulcrum of the electric equipment being hoisted can be adjusted accordingly.

[0022] When lifting power equipment of different lengths and widths, it is necessary to adjust the distance between the four square lifting ropes under the square boom frame in order to better lift the power equipment. At this time, the two rotating arms can be controlled by two rotating cylinders to rotate and the two rotating arms can be rotated out of the square boom frame. At this time, the distance between the four square lifting ropes on the two rotating arms will be reduced. In order to ensure that the four square lifting ropes under the square boom frame are rectangular, the distance between the two adjusting rollers can be controlled by two sliding cylinders, so that the four square lifting ropes under the square boom frame can be rectangular, which has a better lifting effect and solves the problem that the existing power equipment lifting is inconvenient to lift the middle part. At the same time, it avoids the problem that the auxiliary lifting rope hooks occupy the effective height when lifting with auxiliary lifting rope hooks.

[0023] (2) In the present invention, the rotation of the main support arm can be controlled by the action of the arm retraction cylinder. The main support arm can be retracted in the non-working state to reduce the space occupied by the equipment. By extending and retracting the auxiliary arm cylinder, the auxiliary support arm is controlled to extend, and then the supporting cylinder is extended to support the four sides of the lifting equipment on the ground, thereby ensuring the stability of the entire equipment and ensuring safety during the lifting process.

At the same time, a number of square lifting ropes 5110 are provided below the square boom frame 5, and a lifting hook 212 is provided at the end of the square lifting rope 5110. In the process of lifting the power equipment, large power equipment is often encountered, and there is no good fulcrum during the lifting process. At this time, it is necessary to lift it all around. The power equipment can be lifted by the square boom frame 5, the operation is stable, and the lifting height is increased.

[0035] Specifically, refer to Figure 3 and Figure 5As shown, a lifting groove 510 is symmetrically opened at the bottom of the square boom frame 5, and support frames 512 are symmetrically arranged inside the square boom frame 5 and on both sides of the lifting groove 510, and an adjusting roller 513 is slidably arranged between the two support frames 512, and then, a first rope reel 51 is symmetrically arranged inside the square boom frame 5, and the first rope reel 51 is driven by the first motor 511, and then one end of the square lifting rope 5110 is fixed on the first rope reel 51, and then the other end is passed around the adjusting roller 513 and passed through the lifting groove 510; then, a sliding cylinder 514 is arranged inside the square boom frame 5 and on one side of the support frame 512, and the protruding end of the sliding cylinder 514 is fixedly connected to one end of the adjusting roller 513; secondly, a supporting slide groove 5120 is opened on the support frame 512, and both ends of the adjusting roller 513 are slidably arranged in the supporting slide groove 5120. During lifting, the power equipment can be further lifted by the lifting hook 212 through the rotation of the first rope roll 51.

[0036] In addition, a rotating arm 522 is symmetrically arranged inside the square boom frame 5, a lifting hole 524 is opened at one end of the rotating arm 522, a fixed roller 525 is arranged on one side of the lifting hole 524 on the rotating arm 522, and a guide ring 523 is arranged at the other end of the rotating arm 522, and then, a second rope reel 52 is symmetrically arranged inside the square boom frame 5, and the second rope reel 52 is driven by the second motor 521 to fix one end of the square lifting rope 5110 on the second rope reel 52, and then the other end of the square lifting rope 5110 passes through the guide ring 523 and bypasses the fixed roller 525 and passes through the lifting hole 524; at the same time, a rotating groove 520 is symmetrically opened below the square boom frame 5. Specifically, a rotating cylinder 526 is rotatably provided on one side of the rotating arm 522 in the square boom frame 5, and a connecting ear 527 is slidably provided on one side of the square boom frame 5, so that the protruding end of the rotating cylinder 526 is rotatably connected to the connecting ear 527; at the same time, a contact switch 528 is provided on one side of the rotating arm 522 in the square boom frame 5, and the lifting of the equipment by the square lifting rope 5110 is further controlled by the rotation of the second rope reel 52.

At this time, the two rotating cylinders 5 26 Controlling the rotation of the two rotating arms 522 can rotate the two rotating arms 522 out of the square boom frame 5. At this time, the distance between the square lifting ropes 5110 on the two rotating arms 522 will be reduced. In order to ensure that the four square lifting ropes 5110 below the square boom frame 5 are rectangular, the distance between the two adjusting rollers 513 can be controlled by two sliding cylinders 514, so that the square lifting ropes 5110 below the square boom frame 5 can be rectangular, which has a better lifting effect and solves the problem that the existing power equipment lifting is inconvenient to lift the middle part.
