Description

Technical Field

[0001] The utility model relates to the field of large-scale object transportation, in particular to a hoisting device used for fixing a hollow shaft. Background Art

[0002] Various copper wires are used in the manufacturing process of diode leads. The copper wires are all wound around iron shafts. There are many iron shafts, at least more than 500. The iron shafts and copper wires weigh more than 200 kilograms. In the past, operators used a flatbed truck that was as high as a pallet. It was quite laborious to drag the iron shafts onto the truck by hand.

[0003] Then the wire is transported to the front of the heading machine, and the handle of the flatbed cart is lifted. The iron shaft will slide to the floor, making the floor bumpy and deforming the iron shaft. The inside of the iron shaft is hollow.

[0004] If this method is used again, there is a risk of the floor being smashed. As the process improves, very high requirements are placed on the iron shaft, and deformation is not allowed. Therefore, a new transport device is urgently needed that requires easy transport and convenient lifting.

[0005] How to fix the inner wall of the iron shaft is a problem to be solved. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a hanging seat 1 and a pressing assembly 2. The pressing assembly 2 is arranged in the hanging seat 1. The hanging seat 1 is provided with a through hole 11 and a through fixing hole 12. The fixing hole 12 is communicated with the through hole 11.

[0038] The pressing assembly 2 includes a sliding core 21, an elastic member 22, a first slider 23 and a second slider 24. The sliding core 21 is slidably set in the through hole 11. The through hole 11 is vertically set, so the sliding core 21 slides up and down. The two ends of the elastic member 22 are respectively connected to the first slider 23 and the second slider 24. In this application, the elastic member 22 adopts a spring.

[0039] There are two states among the sliding core 21, the first slider 23 and the second slider 24. In the first state, the sliding core 21 is inserted between the first slider 23 and the second slider 24, and the sliding core 21 separates the first slider 23 and the second slider 24. At this time, the first slider 23 and the second slider 24 are away from each other, and the first slider 23 and the second slider 24 slide outward, and the first slider 23 and the second slider 24 both press against the inner wall of the hollow shaft.

[0040] In the second state, the sliding core 21 is away from between the first slider 23 and the second slider 24. Under the action of the elastic member 22, the first slider 23 and the second slider 24 retract inward and return to the initial position. In the initial position, the first slider 23 is located in the first section hole 121, and the second slider 24 is located in the second section hole 122.

[0041] like Figure 4 and Figure 5 and Figure 6 As shown, the suspension seat 1 includes an integrally formed upper seat 13 and a lower seat 14 , both of which are cylindrical. The outer diameter of the lower seat 14 is larger than the inner diameter of the upper seat 13 , that is, the lower seat 14 is thicker than the upper seat 13 , and the upper seat 13 is arranged on the upper surface of the lower seat 14 .

[0042] The fixing hole 12 includes a first hole 121 and a second hole 122, which are respectively located on both sides of the through hole 11. The first hole 121 and the second hole 122 are both located at the bottom of the hanger 1, and the bottom of the hanger 1 is to extend into the hollow shaft.

[0043] The first slider 23 is slidably disposed in the first hole 121 , and the second slider 24 is slidably disposed in the second hole 122 . The first slider 23 and the second slider 24 are close to or away from each other, and there is a gap between the first slider 23 and the second slider 24 .

[0044] The upper seat 13 is provided with a through movable hole 15 and a through side hole 16. The movable hole 15 is communicated with the through hole 11, and the side hole 16 is communicated with the through hole 11. A latch 3 is sleeved in the side hole 16. After the sliding core 21 moves downward, when the sliding core 21 drops to the lowest position, the sliding core 21 is inserted between the first slider 23 and the second slider 24 to prevent the sliding core 21 from resetting upward. The latch 3 is inserted into the side hole 16, so that the latch 3 is blocked at the top of the sliding core 21, so that the sliding core 21 cannot rise. If the sliding core 21 is reset upward, the first slider 23 and the second slider 24 will retract.

[0045] The pressing assembly 2 also includes a pressing handle 25 and a fixed block 26. The fixed block 26 is arranged on the upper surface of the lower seat 14. The length direction end of the pressing handle 25 is hingedly arranged on the fixed block 26. The other end of the pressing handle 25 can be lifted upward. The pressing handle 25 passes through the movable hole 15. The pressing handle 25 can be raised or lowered to a set height in the movable hole 15. The sliding core 21 is slidably sleeved on the pressing handle 25, and the sliding core 21 rises or falls with the pressing handle 25.

[0046] A first slide groove 141 and a second slide groove 142 are provided at the bottom of the lower seat 14, the first slide groove 141 is communicated with the first section hole 121, and the second slide groove 142 is communicated with the second section hole 122. A first connecting rod 27 is provided on the first slider 23, and the first connecting rod 27 passes through the first slide groove 141. A second connecting rod 28 is provided on the second slider 24, and the second connecting rod 28 passes through the second slide groove 142. Both ends of the elastic member 22 are respectively connected to the first connecting rod 27 and the second connecting rod 28, and the elastic member 22 is located in the sliding direction of the sliding core 21.

[0047] The pressing handle 25 is bent so that it is easier to operate with force. The downwardly extending end of the sliding core 21 contracts as it extends. The downwardly extending end of the sliding core 21 is a pointed end, which facilitates the sliding core 21 to be inserted downward between the first slider 23 and the second slider 24.

[0048] A boss 4 protruding outward is arranged on the top of the outer periphery of the lower seat 14 . The boss 4 surrounds the top of the outer periphery of the lower seat 14 . The boss 4 plays a reinforcing role. The fixing block 26 can also be arranged on the boss 4 .

[0049] A fixing cap 5 is disposed at the top of the lower seat 14 , and the fixing cap 5 covers the through hole 11 . The fixing cap 5 is fixed to the top of the lower seat 14 by screws.

[0050] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
