It typically moves on rails, using a motor to drive a chain or belt to lift and transport the load. However, the rails used in most current factories are fixed and cannot be adjusted, restricting the hoist to a fixed path. This makes it difficult to flexibly meet the needs of transporting loads to different locations, such as loading multiple processing machines. Utility Model Content

The lifting mechanism of the electric hoist is installed on the connecting part, and each sliding part is provided with two wheels, one of which rotates forward and the other backward, and its rotating shaft is along the horizontal direction, and a first motor is provided to drive the wheels to rotate, which is used to drive the wheels to roll on the bottom of the groove of the slide. Each sliding part is provided with a front and a rear spring extending toward the side groove wall of the slide where it is located. One end of the spring is connected to the sliding part, and the other end is provided with a mounting block. A pressure wheel is rotatably provided on each mounting block, and the rotating shaft of the pressure wheel is along the vertical direction, and the pressure wheel rolls and contacts with the side groove wall of the slide. Under the action of the springs on both sides, the pressure wheels on both sides will be pressed against the side groove wall of the slide.

[0005] In one embodiment, the first track is fixedly connected to the upper end of the factory building by having a plurality of first suspension rods fixed upward on both sides.

[0006] In one embodiment, multiple second hangers are fixedly connected to the two sides of the second track extending upward, and multiple semicircular second slide rails are fixedly provided at the upper end of the factory building. With the rotating axis of the second track as the center, the radius of the second slide rail is larger as the distance increases.

The second rail 4 is located on the same horizontal plane as the first rail 1, and the cross section of the second rail 4 is also an I-shape, with both sides recessed inward to form two slide grooves 9. The second rail 4 has the same cross-sectional dimensions as the first rail 1. A semicircular block 5 with a vertical axis is fixed to one end of the second rail 4 by welding, and the end is rotatably arranged beside one end of the first rail 1, with its rotating shaft in the vertical direction, and the axis direction of the semicircular block 5 coincides with its rotating shaft direction. The drive motor 10 is used to drive the second rail 4 to rotate. Furthermore, the slide groove 9 on the second rail 4 passes through the semicircular block 5, and a slide groove 9 is also formed on the semicircular block 5.

[0025] See also Figure 1 、 Figure 2 In one embodiment, the first track 1 is fixedly connected to the upper end of the factory building by having a plurality of first hangers 2 fixed vertically upward on both sides. The lower ends of the first hangers 2 are fixedly connected to the first track 1 by welding, and the upper ends are fixed to the roof of the factory building by welding. This arrangement provides a relatively stable structure.

[0026] See also Figure 6 、 Figure 7 In one embodiment, both sides of the second track 4 extend upward in the vertical direction and are fixedly connected to a plurality of second suspension rods 6. A plurality of second slide rails 7 in the shape of a semicircle in the horizontal plane are fixedly provided at the upper end of the factory building. These second slide rails 7 are all centered on the rotation axis of the second track 4, and the radius of the second slide rail 7 is larger the farther away from the rotation axis of the second track 4. The plurality of second suspension rods 6 are respectively slidably connected to the second slide rails 7 along the rotation direction of the second track 4. Each of the second slide rails 7 is slidably provided with two second suspension rods 6 on the left and the right. The cross section of the second slide rail 7 is in the shape of a "convex" character. The upper end of the second suspension rod 6 is correspondingly provided with a protrusion, so that the second slide rail 7 can provide support for the second suspension rod 6 and limit its vertical position. With this arrangement, the structural effect is relatively stable.

[0027] See also Figure 2In one embodiment, a second gear 8 is fixedly provided at the rotating shaft of the second track 4 by welding, and its central axis coincides with the rotating shaft of the second track 4. A driving motor 10 is fixedly provided on the first track 1 by welding or threaded connection or other conventional methods. A first gear 3 is fixedly provided on the output shaft of the driving motor 10 by welding, and the first gear 3 is meshed with the second gear 8. In this way, the second track 4 is driven to rotate by gear transmission, which is stable and easy to implement.

[0028] See also Figure 3 、 Figure 5 The traveling part includes two sliding parts 11, and the two sliding parts 11 are respectively arranged in the two chutes 9. The two sliding parts 11 are fixedly connected by a connecting part 17 from below, bypassing the first rail 1 or the second rail 4. The fixed connection method can be welding. The lifting mechanism 18 of the electric hoist is installed at the lower end of the connecting part 17. The specific structure of the lifting mechanism 18 is the existing technology and will not be introduced in detail here. Two wheels 12 are arranged on each sliding part 11, one rotating in front and the other rotating in the horizontal direction, and a first motor 13 is provided to drive the wheels 12 to rotate. The housing of the first motor 13 is fixedly mounted on the sliding part 11, and its output shaft is welded to the rotating shaft of the wheel 12, which is used to drive the wheel 12 to roll on the bottom of the chute 9, and the forward or backward movement of the traveling part is achieved by the forward and reverse rotation of the first motor 13.

[0029] See also Figure 3 、 Figure 5On each of the sliding parts 11, there are two springs 14 extending toward the side groove wall of the slide 9 in which it is located. The central axis of the spring 14 is in the horizontal direction. One end of the spring 14 is connected to the sliding part 11 by welding, and the other end is provided with a mounting block 15 by welding. A pressure wheel 16 is rotatably installed on each of the mounting blocks 15. The rotating axis of the pressure wheel 16 is in the vertical direction, and the pressure wheel 16 rolls in contact with the side groove wall of the slide 9. Under the action of the springs 14 on both sides, the pressure wheels 16 on both sides will be pressed against the side groove wall of the slide 9. With such arrangement, during the movement of the traveling part, under the action of the springs 14 on both sides, the pressure wheels 16 on both sides will be pressed against the side groove walls of the slide groove 9. When traveling from the first track 1 to the second track 4, even if there is a brief change in the gap width in the middle, the pressure wheels 16 will contact the side groove walls of the slide groove 9 or the side walls of the semicircular block 5 under the action of the springs 14. After traveling on the second track 4, under the elastic force of the springs 14 on both sides, the center of the traveling part will be pulled back to a balanced state, so that it adapts to the direction of the second track 4 and continues to travel along the second track 4. Conversely, the process of traveling from the second track 4 to the first track 1 is the same, and the structural effect is relatively stable.

[0030] See also Figure 2 In one embodiment, preferably, the spacing between the semicircular block 5 and the first rail 1 is 1 cm. This is set because a smaller gap can better ensure the stability of the driving part in transferring between the first rail 1 and the second rail 4.
