Description

Technical Field

[0001] The present application relates to the technical field of electric hoists, and in particular to a winding type wire rope electric hoist. Background Art

[0002] An electric hoist is a small lifting equipment that integrates an electric motor, a reducer and a wire rope drum or a chain. Existing electric hoists are generally equipped with a torque limiting device. When the load lifted by the electric hoist exceeds the upper limit of the use of the electric hoist, the torque limiting device limits the lifting of the electric hoist by slipping, which can effectively avoid overloading of the electric hoist and ensure the safety of the electric hoist during the lifting process.

[0003] When performing lifting operations, a lifting rope is tied to the object to be lifted, and then the top of the lifting rope is hung on a hook. The motor drives the steel rope to be reeled in to directly lift the object. The electric hoist is moved left and right in parallel by sliding the pulley set on the track at the top of the electric hoist. Finally, the motor drives the steel rope to unwind and put the object down. In this process, the object is likely to deviate from the vertical steel rope due to the center of gravity of the object during lifting. After lifting, the center of gravity of the object and the object will move in the direction of the vertical steel rope, causing the steel rope to swing easily, which may collide with other objects or workers. After the object is lifted to a high altitude, the object is easily affected by the airflow and swings, which is less safe. Therefore, those skilled in the art provide a winding wire rope electric hoist to solve the problems raised in the above background technology. Utility Model Content

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application discloses a winding wire rope electric hoist, referring to Figure 1-4, including an electric hoist body 1, a first motor 2 and a first cable 3, the bottom end of the electric hoist body 1 is connected to a limit mechanism 4, and one end of the first cable 3 is arranged in the limit mechanism 4, both sides of the electric hoist body 1 are fixedly installed with protective covers 5, the first motor 2 is fixedly installed on one side of a protective cover 5, and the two protective covers 5 are both installed with a driving mechanism 6; the limit mechanism 4 includes a limit plate 7, one side of the limit plate 7 is provided with a slide groove 8, and two limit members 9 are slidably installed in the slide groove 8, and one end of the two limit members 9 Both are equipped with a driving member 10, and second cables 11 are fixedly installed around the limiting plate 7. One end of the four second cables 11 is woundly connected with a winch 12, and the four winches 12 are rotatably installed on both sides of the electric hoist body 1; the two driving mechanisms 6 each include two gears 13 that are meshed with each other, one side of the two gears 13 is respectively fixedly connected to one end of the two winches 12 on the same side, and a driven wheel 14 is fixedly installed on the other side of one gear 13, and a driving wheel 15 is fixedly installed on both sides of the output shaft of the first motor 2.

[0027] By adopting the above technical scheme, the utility model sets a limit mechanism 4, which is convenient for driving the first motor 2 to pay out the first cable 3. The two sides of the first motor 2 can drive the gear 13 to rotate through the driving wheel 15 and the driven wheel 14, thereby driving the winch 12 to pay out the second cable 11, and then the limit plate 7 and the hook at the bottom end of the first cable 3 can be made to move synchronously. When the lifting hook lifts the weight, the limit plate 7 can limit the distance between the hook and the limit plate 7, thereby reducing the swing of the weight due to the unstable center of gravity, which can improve safety.

[0028] Reference Figure 1 and Figure 2 The output shaft of the first motor 2 is drivingly connected to the electric hoist body 1, and the first cable 3 is installed on the electric hoist body 1 in a winding manner.

[0029] By adopting the above technical solution, it is convenient to control the winding and unwinding operations of the first cable 3 by driving the first motor 2 to rotate.

[0030] Reference Figure 1 , Figure 2 and Figure 4 The limiting member 9 includes two limiting blocks 16, which are respectively slidably installed in the slide groove 8, and the first cable 3 is arranged between the two limiting blocks 16. The top ends of the two limiting blocks 16 are fixedly installed with connecting rods 17, and one end of the two connecting rods 17 is movably connected to one side of the driving member 10.

[0031] By adopting the above technical solution, the two limit blocks 16 can conveniently limit the range of movement of the first cable 3, so that the first cable 3 can be kept in a vertical state due to the gravity of the hook, thereby preventing the first cable 3 in the electric hoist body 1 from loosening, and the range of movement of the first cable 3 can also be limited to improve stability.

[0032] Reference Figure 1 and Figure 4 A limiting rod 18 is fixedly installed on one side of the two limiting blocks 16, and the two limiting rods 18 are movably installed in the slide groove 8.

[0033] By adopting the above technical solution, it is convenient to thread the adjusting screw 20 in the adjusting groove 19, so that the adjusting screw 20 is turned to move the adjusting screw 20 in the adjusting groove 19, thereby controlling the two limit blocks 16 to move in the slide groove 8, adjusting the distance between the two limit blocks 16, and changing the movable range of the first cable 3 between the two limit blocks 16.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The driving member 10 includes a driving screw 21, both ends of which are fixedly connected to the top of the limiting plate 7 through connecting plates. A driving block 22 is threadedly mounted on the driving screw 21, and a movable groove 23 is opened on one side of the driving block 22. One end of the two connecting rods 17 are movably mounted in the movable groove 23.

[0035] By adopting the above technical solution, it is convenient to drive the driving screw 21 to rotate, so that the driving block 22 moves on the driving screw 21, and then drive the two limit blocks 16 to move through the connecting rod 17, thereby guiding the first cable 3 to reel in and unreel.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A second motor 24 is fixedly mounted on one end of the driving screw rod 21 , and the second motor 24 and the first motor 2 are both externally connected to a controller.

[0037] By adopting the above technical solution, it is convenient to drive the first motor 2 and the second motor 24 to rotate simultaneously through an external controller, so that when the first motor 2 pays out the first cable 3, the second motor 24 can control the driving block 22 to move on the driving screw 21, and then drive the two limit blocks 16 to slide in the slide groove 8 through the connecting rod 17, so as to guide the first cable 3 to pay out. Similarly, when the first cable 3 is reeled in, the first cable 3 can also be guided to reel in, so that the first cable 3 can maintain order when paying out and reeling in, ensuring the flatness of the first cable 3 on the reeling roller of the first cable 3 to avoid interlacing when winding.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The driving wheel 15 and the driven wheel 14 located on both sides of the electric hoist body 1 are connected through a transmission belt.

[0039] By adopting the above technical solution, the first motor 2 can drive the gear 13 to rotate through the driving wheel 15 and the driven wheel 14. The two gears 13 are meshed with each other, so as to drive the two capstans 12 on the same side to rotate in opposite directions, so that the two capstans 12 can perform the operations of paying out and taking up the line at the same time, and the limit plate 7 can move up and down simultaneously with the hook at the bottom end of the first cable 3.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The slide groove 8 is vertically arranged with respect to the first cable 3 , and the bottom end and one side of the slide groove 8 respectively penetrate the bottom end and one side of the limiting plate 7 .

[0041] By adopting the above technical solution, the first cable 3 is in a vertical state due to the gravity of the hook, and the first cable 3 can move in the slide groove 8, avoiding contact with the edge of the slide groove 8, thereby reducing the wear of the first cable 3.
