Technical Field

[0001] The utility model relates to the technical field of hoists, in particular to a hoist with a stable supporting structure. Background Art

[0002] A hoist is a lifting device that can be used to lift and install boiler equipment. The hoist is usually composed of steel components, including steel cables, hooks, beams and other components. The main function of the hoist is to provide safe and reliable lifting support during the installation of the boiler to ensure that the boiler can be accurately installed in the designated position and to ensure the safety of personnel and equipment during the lifting process, helping workers to quickly and efficiently complete the lifting and installation of boiler equipment, saving construction time and improving construction efficiency.

[0003] When the hoist is lifting the boiler for installation, it is necessary to hang the lifting rope on the boiler, and then use the lifting rope to lift the boiler and move it. The lifting rope is generally made of wire rope, so that the lifting rope has a certain bending ability. When the hoist is lifting and moving, the lifting rope will be affected by the gravity of the hoisted goods and move vertically downward. At this time, the hoist is pushed, and the goods on the lifting rope will be affected by inertia, causing the lifting rope to swing left and right, which will affect the stability and safety of the boiler lifted by the hoist. Therefore, we proposed a hoist with a stable support structure. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are: the lifter with a stable supporting structure starts the electric push rod, so that the connecting frame squeezes and limits the boiler, starts the brake motor, moves the boiler upward, pushes the lifter, and supports and limits the boiler through the connecting frame. When the boiler is moved by the lifting rope, the lifting rope is not easy to swing left and right, and will not affect the stability and safety of the lifting of the lifter. The boiler is in contact with the ground, so that the connecting frame pushes the docking frame upward, causing the connecting spring to contract, so that the connecting spring can buffer the impact force of lowering the boiler, so that the lifter can provide buffering when placing the boiler.

A second slide groove 211 is provided on the side of the connecting plate 210 close to the slide 209. The slide 209 is slidably connected to the second slide groove 211. A connecting frame 212 is provided at the end of the connecting plate 210 away from the slide plate 206, and a connecting pad 213 is bonded to the side of the connecting frame 212 close to the boiler 102. A first bevel gear 3 is fixed to one side of the winding wheel 202, and the first bevel gear 3 is connected to the second bevel gear 301. The first bevel gear 3 and the second bevel gear 301 are movably connected to the bracket 1 through the bearing seat respectively, and one side of the second bevel gear 301 is fixed to the output shaft of the brake motor 302, and the brake motor 302 is fixed to the bracket 1 through the mounting frame. The cross-sectional size of the first slide groove 204 matches the cross-sectional size of the slide plate 206, and the cross-sectional size of the slide 209 matches the cross-sectional size of the second slide groove 211. The connecting pad 213 is made of rubber, and the first bevel gear 3 and the second bevel gear 301 are meshingly connected.

[0025] In specific implementation, according to Figure 1-Figure 6When the hoist is lifting the boiler 102 for installation, it is necessary to connect the hook of the lifting rope 2 with the lifting ring of the boiler 102, and then start the electric push rod 208, so that the output rod of the electric push rod 208 pushes the slide 209 to slide along the second slide groove 211. At this time, the slide 209 will lift the connecting plate 210 along the second slide groove 211, so that the connecting plate 210 lifts the connecting frame 212 through the docking frame 4 to squeeze the boiler 102. The connecting pad 213 is made of rubber material with a certain deformation ability, so that the connecting frame 212 strengthens the extrusion limit of the boiler 102. At this time, the brake motor 302 is started, and the two ends of the brake motor 302 respectively drive the second bevel gear 301 to rotate, and the first bevel gear 3 is meshed and docked with the second bevel gear 301, so that the first bevel gear 3 rotates with the second bevel gear 301. At this time, the first bevel gear 3 drives the winding wheel 202 to rotate. The winding wheel 202 can wind up the lifting rope 2 and the connecting rope 207, and the lifting rope 2 and the connecting rope 207 are respectively wound on the surface of the winding wheel 202 through the first guide wheel 201 and the second guide wheel 205, so that the lifting rope 2 lifts the boiler 102, and while the boiler 102 moves up, the connecting rope 207 lifts the slide plate 206 and moves up along the first slide groove 204. The cross-sectional size of the first slide groove 204 matches the cross-sectional size of the slide plate 206, so that the slide plate 206 does not shake when moving up along the first slide groove 204. At this time, the connecting frame 212 is still restricted to the outside of the boiler 102, pushing the hoist, so that the hoist lifts the boiler 102 and moves it. At this time, the connecting frame 212 supports and limits the boiler 102, so that when the lifting rope 2 lifts the boiler 102 to move, the goods on the lifting rope are not easily affected by inertia, and the lifting rope 2 is not easy to shake left and right, which will not affect the stability and safety of the lifting of the hoist.

[0026] See also Figure 1 and Figure 6 The connecting plate 210 slides inside one end of the connecting frame 212 and penetrates the docking frame 4, and the support rod on the lower side of the docking frame 4 penetrates the connecting spring 401 and is fixed to the connecting frame 212, and the two ends of the connecting spring 401 are respectively connected to the connecting plate 210 and the connecting frame 212, a docking rod 402 is fixed to one side of the connecting plate 210 close to the docking frame 4, and a fixing pad 403 is bonded to the lower end of the docking rod 402, the docking rod 402 is slidably docked with the docking tube 404, and the docking tube 404 is fixed to the connecting frame 212, the fixing pad 403 is made of rubber material, and the fixing pad 403 is squeezed against the inner side of the docking tube 404, and a damper 405 is installed between the connecting plate 210 and the connecting frame 212.

[0027] In specific implementation, according to Figure 1 and Figure 6When the hoist lowers the hoisted boiler 102, the brake motor 302 is started to make the winding wheel 202 rotate in the opposite direction, so that the winding wheel 202 lowers the wound lifting rope 2 and the connecting rope 207. At this time, the boiler 102 is in contact with the ground. At this time, the connecting frame 212 clamps and limits the boiler 102, so that the connecting frame 212 pushes the docking frame 4 to move upward, and the connecting spring 401 contracts, so that the connecting spring 401 can buffer the impact force of lowering the boiler 102. At this time, the docking rod 402 moves along the inner side of the fixed pad 403. The fixed pad 403 is made of rubber material with a certain deformation ability, and the fixed pad 403 is squeezed with the inner side of the docking pipe 404, so that the connecting spring 401 slows down the repeated bounce, and then the installed damper 405 further eliminates the repeated bounce of the connecting spring 401, so that the hoist can buffer when placing the boiler 102.

[0028] To sum up, when the hoist is lifting the boiler 102 for installation, it is necessary to hang the hook of the lifting rope 2 with the lifting ring of the boiler 102, start the electric push rod 208, make the connecting frame 212 squeeze and limit the boiler 102, start the brake motor 302, lift the boiler 102, push the hoist, and support and limit the boiler 102 through the connecting frame 212, so that when the lifting rope 2 lifts the boiler 102 to move, the lifting rope 2 is not easy to swing left and right, and will not affect the stability and safety of the lifting of the hoist. When the hoist puts down the lifted boiler 102, the boiler 102 contacts the ground, so that the connecting frame 212 pushes the docking frame 4 to move up, and the connecting spring 401 contracts, so that the connecting spring 401 can buffer the impact force of lowering the boiler 102, so that the hoist can buffer when placing the boiler 102.
