[0015] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0016] Embodiment 1: like Figure 1 As shown, a steel structure construction auxiliary lifting equipment includes a crossbeam 1 and a lifting rope 3. A guide wheel 2 for pulling and guiding the lifting rope 3 is arranged at the upper edge of one end of the crossbeam 1, and a hanging piece 4 is arranged at the lower end of the lifting rope 3.

[0017] like Figure 1 , Figure 2 As shown, the hanging member 4 includes a track 41, and two movable sleeves 42 are symmetrically and laterally slidably installed on the outside of the track 41. A hook 43 is provided at the lower part of the movable sleeve 42. The distance between the two movable sleeves 42 is adjusted according to the length of the steel workpiece, and then the steel workpiece is lifted by the hook 43.

[0018] like Figure 1 , Figure 3 As shown, an anti-collision mechanism 5 is provided at the bottom of the beam 1, and the anti-collision mechanism 5 includes a driving servo motor 51 installed at one end of the beam 1, and a strip groove is provided at the bottom of the beam 1, and the output shaft of the driving servo motor 51 is located in the strip groove and horizontally connected with a screw rod 52, and the outside of the screw rod 52 is screwed with an L-shaped beam 53 through a thread.

[0019] like Figure 1 , Figure 3 As shown, the anti-collision mechanism 5 also includes a limiting seat 54, one end of which is provided with a hinge groove 56, and the limiting seat 54 is hinged to the end of the L-shaped beam 53 away from the screw rod 52 through the hinge groove 56, and the upper part of the end of the limiting seat 54 away from the L-shaped beam 53 is provided with a through guide groove 55 for guiding the traction of the lifting rope 3.

[0020] During lifting, the driving servo motor 51 drives the screw 52 to rotate, and the screw 52 drives the L-shaped beam 53 to move laterally, so that the limit seat 54 pushes the lifting rope 3 to move away from the building. In this way, the steel workpiece will not touch the building during lifting. After the steel workpiece is lifted, the driving servo motor 51 works again to make the lifting rope 3 approach the construction workers. In this way, the construction workers do not need to stand at the edge of the building to pull the lifting rope 3, thereby improving safety.

[0021] Embodiment 2: like Figure 1 , Figure 3 As shown, a steel structure construction auxiliary hoisting device, the anti-collision mechanism 5 also includes an adjustment mechanism 57 for adjusting the hoisting direction, the adjustment mechanism 57 includes a gear bar 571 arranged at the upper edge of one end of the limit seat 54 near the L-shaped beam 53 and an adjustment servo motor 572 installed at the lower part of the L-shaped beam 53 near the limit seat 54. The output shaft of the adjustment servo motor 572 is connected to a main gear 573 corresponding to the gear bar 571, and the main gear 573 is meshed with the gear bar 571.

[0022] like Figure 3 As shown, the center of the gear bar 571 and the hinge point of the limiting seat 54 are located on the same axis. When the main gear 573 drives the gear bar 571 to rotate, the gear bar 571 will drive the limiting seat 54 to rotate.

[0023] When the servo motor 572 is adjusted to drive the main gear 573 to rotate, the gear bar 571 will be driven to rotate, and the gear bar 571 will cause the limit seat 54 to rotate, so as to adjust the direction of the steel workpiece hoisting and better prevent the steel workpiece from touching the building.

[0024] Embodiment 3: like Figure 4 , Figure 5 As shown, a steel structure construction auxiliary lifting equipment, the anti-collision mechanism 5 also includes a lubrication assembly arranged on the limit seat 54, the lubrication assembly includes a cavity 541 arranged inside the limit seat 54, an oil storage tank 542 installed at the bottom of the limit seat 54 and a hydraulic cylinder 544 installed on the upper part of the limit seat 54.

[0025] like Figure 4 , Figure 5As shown, the cavity 541 is close to the guide groove 55, the oil storage tank 542 is communicated with the interior of the cavity 541, and a sponge block 543 is vertically connected to the lower side of the interior of the oil storage tank 542.

[0026] like Figure 4 , Figure 5 As shown, the output shaft of the hydraulic cylinder 544 is located in the chamber 541 and connected to the limit block 545, one end of the limit block 545 is hinged with a connecting rod 546, and the bottom of the limit block 545 is connected to the limit shaft 547. The lower end of the limit shaft 547 is connected to a pressure plate 548 that matches the inner diameter of the oil storage tank 542, and the pressure plate 548 is located above the sponge block 1 543.

[0027] like Figure 4 , Figure 5 As shown, the inner wall of the guide groove 55 is provided with a notch communicating with the interior of the cavity 541, and a concave plate 549 is slidably disposed in the notch. One end of the connecting rod 546 away from the limiting block 545 is hinged to the side of the concave plate 549 away from the guide groove 55, and the four corners of the side of the concave plate 549 away from the guide groove 55 are connected to the inner wall of the cavity 541 through four limiting springs 5410.

[0028] like Figure 4 , Figure 5 As shown, the upper part of the pressing plate 548 is connected with an oil delivery pipe 5411, and one end of the oil delivery pipe 5411 extends to the lower part of the pressing plate 548. A cavity is provided inside the concave plate 549, and the other end of the oil delivery pipe 5411 is communicated with the cavity inside the concave plate 549.

[0029] like Figure 4 , Figure 5 As shown, the inner wall of the concave plate 549 is densely covered with overflow holes 5491, and a second sponge block 5492 is arranged inside the concave plate 549. A clamping groove 5493 is arranged on one side of the second sponge block 5492, and the clamping groove 5493 extends to the side of the second sponge block 5492 close to the guide groove 55, and the inner spacing of the clamping groove 5493 is smaller than the diameter of the suspension rope 3, and the outer spacing is larger than the diameter of the suspension rope 3. When the second sponge block 5492 moves into the guide groove 55, the suspension rope 3 can be clamped into the clamping groove 5493, so as to facilitate the lubrication operation of the suspension rope 3.

[0030] like Figure 4 , Figure 5 As shown, when the output shaft of the hydraulic cylinder 544 is fully retracted, the side of the concave plate 549 close to the guide groove 55 is just set in the notch of the inner wall of the guide groove 55, and the pressing plate 548 is not in contact with the sponge block 1 543. When the output shaft of the hydraulic cylinder 544 is fully extended, the concave plate 549 is just completely in the guide groove 55, and the pressing plate 548 just presses down the sponge block 1 543.

[0031] When the lifting rope 3 needs to be lubricated, the hydraulic cylinder 544 drives the limit block 545 to move downward, and the limit block 545 causes the connecting rod 546 to push the concave plate 549 to move it into the guide groove 55, so that the lifting rope 3 is stuck in the slot 5493 and the lifting rope 3 is wrapped.

[0032] When the limit block 545 moves downward, the limit shaft 547 will also drive the pressure plate 548 to move downward. The pressure plate 548 will press down the sponge block 1 543, and the lubricating oil in the oil storage tank 542 will moisten the sponge block 1 543. Then, when the pressure plate 548 presses down the sponge block 1 543, the oil on the sponge block 1 543 will be pressed into the cavity inside the concave plate 549 through the oil pipe 5411, and then moisten the sponge block 2 5492 through the overflow hole 5491. The sponge block 2 5492 will then use the lubricating oil to moisten the lifting rope 3. In this way, when the lifting rope 3 is moving, the lubricating oil will lubricate various positions on the lifting rope 3.

[0033] After lubrication is completed, the hydraulic cylinder 544 moves the limit block 545 upward, and the connecting rod 546 causes the concave plate 549 to leave the guide groove 55 so that it does not affect the movement of the lifting rope 3, and the pressure plate 548 also leaves the sponge block 543, stopping the use of lubricating oil and saving lubricating oil.

[0034] Working principle: According to the length of the steel workpiece, the distance between the two moving sleeves 42 is adjusted, and then the steel workpiece is lifted by the hook 43. During the lifting, the servo motor 51 is driven to drive the screw 52 to rotate, and the screw 52 drives the L-shaped beam 53 to move horizontally, so that the limit seat 54 pushes the lifting rope 3 to keep it away from the building, so that the steel workpiece will not touch the building during lifting.

[0035] Then, by adjusting the servo motor 572 to drive the main gear 573 to rotate, the gear bar 571 will be driven to rotate, and the gear bar 571 will cause the limit seat 54 to rotate, thereby adjusting the direction of the steel workpiece hoisting and better preventing the steel workpiece from touching the building.

[0036] After the steel workpiece is hoisted, the driving servo motor 51 is operated again to allow the hoisting rope 3 to approach the construction personnel. In this way, the construction personnel do not need to stand at the edge of the building to pull the hoisting rope 3, thereby improving safety.

[0037] When the lifting rope 3 needs to be lubricated, the hydraulic cylinder 544 drives the limit block 545 to move downward, and the limit block 545 causes the connecting rod 546 to push the concave plate 549 to move it into the guide groove 55, so that the lifting rope 3 is stuck in the slot 5493 and the lifting rope 3 is wrapped.

[0038] When the limit block 545 moves downward, the limit shaft 547 will also drive the pressure plate 548 to move downward. The pressure plate 548 will press down the sponge block 1 543, and the lubricating oil in the oil storage tank 542 will moisten the sponge block 1 543. Then, when the pressure plate 548 presses down the sponge block 1 543, the oil on the sponge block 1 543 will be pressed into the cavity inside the concave plate 549 through the oil pipe 5411, and then moisten the sponge block 2 5492 through the overflow hole 5491. The sponge block 2 5492 will then use the lubricating oil to moisten the lifting rope 3. In this way, when the lifting rope 3 is moving, the lubricating oil will lubricate various positions on the lifting rope 3.

[0039] After lubrication is completed, the hydraulic cylinder 544 moves the limit block 545 upward, and the connecting rod 546 causes the concave plate 549 to leave the guide groove 55 so that it does not affect the movement of the lifting rope 3, and the pressure plate 548 also leaves the sponge block 543, stopping the use of lubricating oil and saving lubricating oil.

[0040] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
