Description

Technical Field

[0001] The utility model relates to a hoist, in particular to a screw hoist. Background Art

[0002] A hoist is a device that lifts materials from a lower position to a higher position and completes the feeding. In this way, for some processing equipment with a relatively high feeding position, workers can directly place the materials at a lower position onto the hoist, and the hoist completes the feeding. The lifting mechanism of the hoist generally includes a feeding rod with spiral blades or a conveyor belt module, etc. For different processing equipment, the height of the feeding position is also different. In order to make the hoist applicable to different processing equipment, the inclination angle of the lifting mechanism relative to the base is generally adjustable, so as to adjust the height position of the discharge port on the lifting mechanism. However, when the inclination angle of the lifting mechanism relative to the base increases, the horizontal distance between the discharge port and the base will also become smaller. If the amplitude is large, when the screw hoist approaches the processing equipment, interference may occur between the base and the processing equipment, affecting the alignment of the discharge port and the feeding port of the processing equipment.

[0032] Please refer to Figure 1 and Figure 2 , a spiral elevator, comprising a base 1, an adjustment mechanism 2, a feeding pipe 3, a feeding rod 4, a motor 5, a connecting component 6 and a lifting mechanism 7.

[0033] The base 1 includes a fixed part 1a, a movable part 1b and a counterweight part 1c.

[0034] The fixed part 1a is threadedly provided with telescopic legs 1a1. That is, when the spiral elevator is in use, the telescopic legs 1a1 are extended downward so that the telescopic legs 1a1 touch the ground, thereby fixing the fixed part 1a relative to the ground.

[0035] The movable part 1b passes through the fixed part 1a. Specifically, a linear bearing is provided on the fixed part 1a, and a smooth shaft 1b1 passes through the linear bearing. There are two movable parts 1b, which are respectively fixedly connected to both ends of the smooth shaft 1b1. After the movable part 1b adjusts its position relative to the fixed part 1a, it can also be fixed relative to the adjustment part.

[0036] The movable part 1b is also provided with rollers 1b2 to play a supporting role. After the fixed part 1a is fixed relative to the ground, it is also convenient for the movable part 1b to adjust its position relative to the fixed part 1a.

[0037] In some embodiments, the roller 1b2 on the movable part 1b is equipped with a foot brake.

[0038] The counterweight part 1c is fixedly connected to the first side of the movable part 1b (i.e., the movable part 1b on the first end of the optical axis 1b1).

[0039] The adjustment mechanism 2 is arranged between the movable part 1b and the fixed part 1a, and is used to drive the movable part 1b to adjust its position relative to the fixed part 1a.

[0040] Please refer to Figure 2 and Figure 3 , in some embodiments, the adjustment mechanism 2 is a lead screw module. Specifically, bearing seats are fixedly connected to the bottom surfaces of the two movable parts 1b, the lead screw 2a of the lead screw module is rotatably connected to these two bearing seats, and the fixed part 1a is fixedly connected to the mounting slider 2b of the lead screw module.

[0041] After the fixed part 1a is fixed relative to the ground, rotating the lead screw 2a can drive the movable part 1b to slide relative to the fixed part 1a; when the rotation of the lead screw 2a stops, by using the self-locking of the lead screw 2a, the movable part 1b can be relatively fixed to the adjustment part.

[0042] Please refer to Figure 1 and Figure 5 , in some embodiments, a bolt 1a2 capable of locking the movable part 1b is provided on the fixed part 1a. Specifically, a through hole for the optical axis 1b1 to pass through is provided on the fixed part 1a, and the through hole is provided with a gap communicating with itself and the outside. The bolt 1a2 passes through one side of the gap and is threadedly connected to the other side.

[0043] Before the movable part 1b adjusts its position relative to the fixed part 1a, first loosen the bolt 1a2, and after the adjustment is completed, tighten the bolt 1a2 again so that the movable part 1b can be more stably fixed relative to the adjustment part.

[0044] Please refer to Figure 3 , on the outer wall of the feeding pipe 3 near the first end, there is a feeding port 3a, and on the outer wall near the second end, there is a discharging port 3b. The first end of the feeding pipe 3 is hinged to the fixed part 1a of the base 1. Specifically, the first end of the feeding pipe 3 is fixedly connected with a first connection end 3c through a flange, and the first connection end 3c is hinged to the fixed part 1a of the base 1.

[0045] The feeding rod 4 is provided with a spiral blade 4a and is rotatably connected inside the feeding pipe 3.

[0046] The motor 5 is installed at the second end of the feeding pipe 3 to drive the feeding rod 4 to rotate. Specifically, the second end of the feeding pipe 3 is fixedly connected with a second connection end 3d through a flange. The motor 5 is equipped with a reducer and is fixedly connected to the second connection end 3d, and the output shaft is fixedly connected to the second end of the feeding rod 4.

[0047] Please refer to Figure 1 and Figure 2 , the connecting component 6 includes a first connecting block 6a sleeved on the feeding pipe 3 and a second connecting block 6b hinged to the first connecting block 6a.

[0048] The lifting mechanism 7 is arranged between the second side of the movable part 1b (i.e., the movable part 1b on the second end of the optical axis 1b1) and the second connecting block 6b to drive the second connecting block 6b to rise and fall.

[0049] Please refer to Figure 3 and Figure 4 , in some embodiments, the lifting mechanism 7 is a screw lift. Specifically, the screw lift adopts the installation method of rising and falling with the screw 7f. The installation housing 7a of the screw lift is fixedly connected to the second side of the movable part 1b. A lead screw nut 7b and a rotating shaft 7c are rotatably arranged at the top of the installation housing 7a. The conversion and the lead screw nut 7b are driven by a worm gear 7d and a worm 7e. The top end of the screw 7f is fixedly connected to the second connecting block 6b, and the bottom end slides up and down in the installation housing 7a and is threadedly connected to the lead screw nut 7b. Rotating the rotating shaft 7c can drive the second connecting block 6b to rise and fall.

[0050] By the rising and falling of the second connecting block 6b, the inclination angle of the feeding pipe 3 is adjusted, and the height of the discharge port 3b is adjusted to adapt to different processing equipment. When the second connecting block 6b rises, while the height of the discharge port 3b rises, the horizontal distance between the discharge port 3b and the second side of the movable part 1b will decrease. If the rising height of the second connecting block 6b is relatively high, the horizontal distance between the discharge port 3b and the second side of the movable part 1b will become relatively small. During the process of the screw elevator approaching the processing equipment, the second side of the movable part 1b and the processing equipment may interfere, affecting the alignment of the discharge port 3b and the feed port of the processing equipment. At this time, the fixed part 1a can be fixed relative to the ground, and by adjusting the movable part 1b, the second side of the movable part 1b is made to approach the fixed part 1a. Of course, when the second side of the movable part 1b approaches the fixed part 1a, the inclination angle of the feeding pipe 3 will also change accordingly, and the discharge port 3b will rise accordingly, but the overall amplitude is relatively small, and the horizontal distance between the discharge port 3b and the second side of the movable part 1b increases.
