[0002] With the development of science and technology, the lifting machinery manufacturing industry has made great progress. Lifting equipment is of vital importance to the machinery manufacturing industry, among which small-tonnage lifting equipment is used more frequently. For some small and medium-tonnage lifting equipment, lifting operations that require a large number of repetitive actions require that the sling can achieve multiple lifts with one device, greatly improving the operating efficiency. At present, the existing equipment can already meet the requirements of multiple lifts with one device for small and medium-tonnage lifting equipment. However, during lifting, since the lifting hook rod is fixed, when lifting different goods, the hook rope can only be extended or shortened so that the hook can be fixed on the back load, and then lifting is performed, resulting in the hook not being in a vertical state and the possibility of unhooking, which makes lifting more troublesome. In view of this, we propose a lifting equipment with a multi-point variable position sling. Summary of the invention

An electric telescopic column 3 is fixedly connected to the top outer wall of the base 1, and is used to drive the lifting device 5 to rise and fall, so as to adjust the height of the lifting device 5, so as to facilitate the lifting of different goods. The output end of the electric telescopic column 3 is rotatably connected to a reinforcing support component 4, which is used to strengthen the support effect on the lifting device 5 and prevent the lifting device 5 from being damaged due to excessive weight of the lifting object. The end of the reinforcing support component 4 away from the electric telescopic column 3 is fixedly connected to the lifting device 5, is used for lifting goods of different sizes. The lifting device 5 includes a fixed column 51, on the inner wall of which a screw rod 52 is rotatably connected, and the end of the screw rod 52 away from the reinforcing support component 4 is fixedly connected to a handle 58, and the outer wall of the handle 58 is fixedly connected to a fixing component 59, which is used to limit and fix the handle 58 after adjusting the angle of the hook rod 6 to prevent the handle 58 from rotating during the transportation and lifting of goods, and the rotation of the hook rod 6 causes the hook under the hook rod 6 to detach. Hook rods 6 are arranged on both sides of the lifting device 5, and the lower side of the hook rod 6 is fixedly connected to a hook rope, and the hook rope is fixedly connected to a hook at one end away from the hook rod 6.

[0035] Furthermore, in order to achieve the effect of adjusting the angle of the hook rod 6, the hook rod 6 can be adjusted according to the cargo of different sizes, so that when the hook under the hook rod 6 is fixed to the cargo, the hook rod 6 is in a vertical state, a limited sliding groove 53 is provided on the inner wall of the fixed column 51, and a slider 54 is slidably connected in the limited sliding groove 53, the slider 54 is penetrated by the screw rod 52, and the slider 54 is threadedly connected to the screw rod 52, the screw rod 52 penetrates the driving gear 56, and the screw rod 52 is fixedly connected to the driving gear 56, the screw rod 52 penetrates the hook rod 6, and the screw rod 52 is fixedly connected to the hook rod 6, and the driving gear 56 is meshed with The driving gear 57 and the driven gear 57 are penetrated by the rotating rod 61, and the driven gear 57 is fixedly connected to the rotating rod 61. The two ends of the rotating rod 61 are rotatably connected to the inner wall of the fixed column 51. A through groove 501 is provided on the outer wall of the fixed column 51, and the through groove 501 is penetrated by the hook rod 6. When the staff rotates the handle 58, the screw rod 52 rotates, and then under the action of the limiting slide groove 53, the slider 54 slides on the screw rod 52, and then the driving gear 56 and the driven gear 57 rotate, so as to achieve the effect of adjusting the angle of the hook rod 6. At the same time, the action of the screw rod 52 and the slider 54 can automatically fix the hook rod 6.

[0036] Furthermore, in order to prevent the handle 58 from rotating itself during the transportation and lifting of goods, the fixing assembly 59 includes a cylinder 591, and the cylinder 591 is fixedly connected to the outer wall of the handle 58, and a cushion block 592 is slidably connected to the inner wall of the cylinder 591, and the cushion block 592 is elastically connected to the inner wall of the cylinder 591 through a spring, and the cushion block 592 is penetrated by a clamping rod 593, and the cushion block 592 is fixedly connected to the clamping rod 593, and the clamping rod 593 is clamped with a clamping groove 594, and the clamping groove 594 is provided on the outer wall of the fixing column 51, and the clamping rod 593 is away from the clamping groove 594. The end is rotatably connected with a pull rod 595, and a groove 581 is opened on the outer wall of the handle 58. After pulling the pull rod 595 to drive the locking rod 593 to disengage from the locking groove 594, the pull rod 595 is rotated again to make the pull rod 595 snap into the groove 581 to achieve the limit fixation of the locking rod 593, and the locking rod 593 can be continuously separated from the locking groove 594, which is convenient for the staff to rotate the handle 58. When the locking groove 594 is snapped with the locking rod 593, the handle 58 can be limited and fixed, thereby effectively preventing the handle 58 from rotating during the cargo transportation and lifting project of the device, thereby reducing the occurrence of safety hazards.

[0037] Furthermore, in order to increase the stability of the device when in use, specifically, the stabilizing component 2 includes a cylinder 21, and the cylinder 21 is fixedly connected to the outer wall of the base 1, and a fixing plate 22 is fixedly connected to the output end of the cylinder 21. By starting the cylinder 21, the fixing plate 22 can be driven to rise and fall. When the device is in use, the fixing plate 22 is in contact with the ground, thereby improving the stability of the device when in use.

[0038] In addition, in order to prevent the lifting device 5 from being damaged due to excessive weight of the lifted object during the process of lifting the goods, specifically, the reinforced support assembly 4 includes an electric turntable 41. The electric turntable 41 is an existing known public technology. When the electric turntable 41 rotates, it can rotate with the electric telescopic rod 42.

A reinforcement rod 44 is hinged on the outer wall of the support column 43, and one end of the reinforcement rod 44 away from the support column 43 is hinged on the outer wall of the electric telescopic rod 42. Under the action of the reinforcement rod 44, the support column 43 can have a certain supporting effect on the electric telescopic rod 42, thereby enhancing the stability of the electric telescopic rod 42 when lifting goods.

[0039] In the present invention, when in use, the device is first moved to a designated location, and then the cylinder 21 is started to drive the fixing plate 22 to descend, so that the fixing plate 22 contacts and squeezes the ground, thereby increasing the stability of the device during use. Then, according to the size of the cargo, the handle 58 is rotated to drive the screw rod 52 to rotate, and under the action of the limiting slide groove 53, the slider 54 slides on the screw rod 52, and at the same time, the driving gear 56 rotates to drive the driven gear 57 to rotate, so that the hook rod 6 can adjust the angle, and under the action of the limiting position of the slider 54, the screw rod 52 will not continue to rotate, so that the hook under the hook rod 6 can be fixed to the cargo in the vertical direction to prevent the hook from being separated from the cargo.

[0040] At the same time, after adjusting the angle of the hook rod 6, pull and rotate the pull rod 595 so that the pull rod 595 can be stuck in the groove 581. At this time, under the action of the spring, the clamping rod 593 is engaged with the clamping groove 594 to achieve the limit fixation of the handle 58, thereby achieving the effect of fixing the screw rod 52, effectively preventing the device from being hooked off during the transportation and lifting of goods. At the same time, through the use of the electric turntable 41, it is convenient to adjust the orientation of the goods after lifting.
