Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a waste steel processing crane with an anti-sway function. Background Technique

[0002] Waste steel refers to various mechanical equipment, transportation vehicles, agricultural machinery, tools, building materials, military supplies, daily necessities, etc. made of steel materials after a certain service life; or waste products, scraps and iron-containing waste generated during the production of these products; or obsolete products replaced due to technological progress and backward economic indicators. Generally speaking, steel products that have lost their original use value are waste steel, and waste steel needs to be transported by a crane during the transportation process.

[0003] For example, a sling of a steel crane disclosed in Chinese Patent (CN208631933U) includes a fixed pulley and a hook. A pulley groove is provided in the middle of the surface of the pulley. A pulley shaft is installed horizontally in the middle of the pulley. Bearings are installed on both sides of the pulley shaft. A bushing is installed on the outer surface of the pulley shaft at the gap between the bearing and the pulley shaft. The two ends of the bearing are connected to side plates by bolts. A first cross beam is horizontally and fixedly installed near the lower position between the two side plates. A hook is vertically and fixedly connected to the lower end of the first cross beam. A second cross beam is horizontally and fixedly installed near the upper position between the two side plates. The utility model can effectively reduce the wear of the steel wire rope and the pulley shaft and increase its service life by installing a bushing on the outer surface of the pulley shaft at the gap between the bearing and the pulley shaft.

[0004] The above solution still has the following technical deficiencies. The crane of the above solution will generate vibrations inside during operation. The steel wire rope is easily swayed by the vibrations, and the lifted waste steel will also move horizontally accordingly. As a result, both the waste steel and the steel wire rope will sway more or less. Based on this, a waste steel processing crane with an anti-sway function is proposed. Content of the Utility Model

A limiting cylinder is fixed to the inner wall of the mounting plate. A plurality of telescopic rods are fixed to the top side of the mounting plate.

[0008] Further, the moving mechanism includes a fixing plate fixed to the top side of the top plate. A second motor is fixed to the left side of the fixing plate. The output shaft of the second motor is fixed with a lead screw. A moving plate is threadedly connected to the outer surface of the lead screw.

[0009] Further, the top ends of the telescopic rods are fixed to the bottom side of the top plate. The plurality of telescopic rods and the hydraulic cylinder are distributed in an annular array.

[0010] Further, the limiting cylinder is sleeved on the outer surface of the lifting rope. The cross section of the mounting plate is annular.

[0011] Further, the bottom sides of the two vertical plates are fixed to the top side of the moving plate. The right end of the rotating shaft is rotatably connected to the left side of the right vertical plate.

[0012] Further, two limiting grooves are opened in the top side of the inner wall of the top plate. The two limiting blocks can slide within the corresponding limiting grooves.

The anti-sway mechanism 300 is used to prevent the lifting rope 7 and the scrap steel from swaying randomly. The first motor 5 is used to drive the rotating shaft 6 to rotate, and the rotating shaft 6 is used to wind up the lifting rope 7.

[0025] Please refer to Figures 1 to 3 , in order to prevent the lifting rope 7 from swaying during work, the anti-sway mechanism 300 in this embodiment includes a hydraulic cylinder 301 fixed on the bottom side of the top plate 1. The telescopic end of the hydraulic cylinder 301 is fixed with a mounting plate 302. The cross section of the mounting plate 302 is circular. A limiting cylinder 303 is fixed on the inner wall of the mounting plate 302. The limiting cylinder 303 is sleeved on the outer surface of the lifting rope 7. A plurality of telescopic rods 304 are fixed on the top side of the mounting plate 302. The top ends of the telescopic rods 304 are fixed to the bottom side of the top plate 1. The plurality of telescopic rods 304 and the hydraulic cylinder 301 are distributed in an annular array.

[0026] The anti-sway mechanism 300 in this embodiment can drive the mounting plate 302 and the limiting cylinder 303 to move up and down through the hydraulic cylinder 301. The limiting cylinder 303 can limit the lifting rope 7, and the telescopic rods 304 are used to ensure the stability of the mounting plate 302 during movement.

[0027] It should be noted that lubricating oil can be applied to the surface of the lifting rope 7 during use to reduce the friction between the lifting rope 7 and the inner wall of the limiting cylinder 303.

[0028] Please refer to Figure 1 , Figure 4 and Figure 5, in order to facilitate the orderly winding of the lifting rope 7 on the rotating shaft 6, the moving mechanism 200 in this embodiment includes a fixing plate 201 fixed to the top side of the top plate 1. A second motor 202 is fixed to the left side of the fixing plate 201. A lead screw 203 is fixed to the output shaft of the second motor 202. A moving plate 204 is threadedly connected to the outer surface of the lead screw 203. The bottom sides of the two vertical plates 4 are fixed to the top side of the moving plate 204. A threaded hole 205 is formed in the front side of the moving plate 204. The lead screw 203 is threadedly connected to the threaded hole 205. Two limiting blocks 206 are fixed to the bottom side of the moving plate 204. Two limiting grooves are formed in the top side of the inner wall of the top plate 1.

[0029] In the moving mechanism 200 of this embodiment, the second motor 202 can drive the lead screw 203 to rotate. The lead screw 203 is used to drive the moving plate 204 to move left and right. By driving the rotating shaft 6, the moving plate 204 can wind the lifting rope 7 orderly on the rotating shaft 6.

[0030] It should be noted that the limiting blocks 206 can limit the moving plate 204 by sliding in the limiting grooves.

[0031] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.

[0032] The working principle of the above embodiment is as follows:

[0033] When it is necessary to lower the lifting rope 7, start the first motor 5. The output shaft of the first motor 5 rotates to drive the rotating shaft 6 to rotate. The rotating shaft 6 releases the lifting rope 7. At the same time, start the second motor 202. The output shaft of the second motor 202 rotates to drive the lead screw 203 to rotate. The lead screw 203 drives the moving plate 204 to move by rotating in the threaded hole 205. The moving plate 204 drives the limiting block 206 to slide in the limiting groove. At the same time, the moving plate 204 drives the rotating shaft 6 to move. The lifting rope 7 moves downward through the rectangular hole 207. Then start the hydraulic cylinder 301. The telescopic end of the hydraulic cylinder 301 extends to drive the mounting plate 302 to move downward. The mounting plate 302 drives the limiting cylinder 303 to move downward. The limiting cylinder 303 limits the lifting rope 7. When the hook 8 reaches the appropriate height, turn off the first motor 5, the second motor 202 and the hydraulic cylinder 301. Hang the scrap iron on the hook 8. Then start the first motor 5, the second motor 202 and the hydraulic cylinder 301. The first motor 5 drives the rotating shaft 6 to wind up the lifting rope 7. The second motor 202 drives the rotating shaft 6 to move, so that the lifting rope 7 can be wound up on the rotating shaft 6 in an orderly manner. The hydraulic cylinder 301 drives the limiting cylinder 303 to move together with the lifting rope 7, so as to prevent the lifting rope 7 and the scrap iron from swinging randomly.
