Description

Technical Field

[0001] The utility model relates to the technical field of crucible fixture devices, in particular to a hoisting fixture that utilizes the self-weight of a single-hole crucible. Background Technique

[0002] During the production process of single-hole graphite crucibles, multiple processes such as molding, roasting, and processing are involved. In each process, it is necessary to hoist and move the product, that is, the single-hole graphite crucible. When hoisting the product, most manufacturers generally use the method of hoisting and moving the crucible product through a steel wire rope. However, in the actual operation process, there are many inconveniences in this method, such as low hoisting efficiency, easy to fall off during hoisting, posing a safety hazard, and the steel wire rope solution damaging the surface of the crucible. Therefore, this application specifically proposes a hoisting fixture that utilizes the self-weight of a single-hole crucible. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a hoisting fixture that utilizes the self-weight of a single-hole crucible. The technical solution to solve the problem is that it includes a vertical shaft. It is characterized in that a lifting lug is coaxially and fixedly connected to the upper end of the vertical shaft, a mounting seat is coaxially and fixedly connected to the lower end of the vertical shaft, a mounting sleeve is coaxially and slidably connected to the vertical shaft, and the mounting sleeve is connected with four groups of fixture components evenly distributed around its axis;

[0004] Each group of the fixture components includes an outer support rod hinged to the mounting sleeve. The lower end of the outer support rod is hinged to a first fastener. The upper end of an inner support rod is hinged to the upper part of the outer support rod. The lower end of the inner support rod is hinged to the mounting seat. The upper end of a connecting rod is fixedly connected to the middle of the inner support rod. The lower end of the connecting rod is hinged to a second fastener. The first fastener and the second fastener have the same structure;

[0005] The first fastener includes a first buckle plate hinged to the lower end of the outer support rod. The first buckle plate is fixedly connected with a first rubber pad. The first buckle plate is also fixedly connected with a first counterweight.

[0006] Preferably, the second fastener includes a second buckle plate hinged to the lower end of the inner support rod. The second buckle plate is fixedly connected with a second rubber pad. The second buckle plate is also fixedly connected with a second counterweight.

[0007] Preferably, the outer surfaces of the first rubber pad and the second rubber pad are both provided with patterns.

[0008] The beneficial effects of the utility model are:

[0009] The multiple sets of fixture components provided in this application can clamp multiple single-hole crucibles simultaneously, thereby ensuring the hoisting efficiency. When hoisting a single-hole crucible, the fixture components contact the inner wall of the crucible through the first rubber pad and the second rubber pad, preventing the surface of the single-hole crucible from being scratched. Moreover, the contact surfaces of the first rubber pad and the second rubber pad with the crucible are arranged with patterns, thereby increasing the frictional force and preventing the crucible from falling off during hoisting. The safety during the operation is relatively high. This application has a simple structure, is easy to use, and has strong practicability. Description of the Drawings

Detailed Description of the Invention

[0017] The following further elaborates in detail on the specific implementation manners of the present utility model in conjunction with the attached Figures 1-5 drawings.

[0018] Example 1. The technical solution it solves is that the multiple sets of fixture components 5 provided in this application can clamp multiple single-hole crucibles 17 simultaneously, thereby ensuring the hoisting efficiency. When hoisting a single-hole crucible 17, the fixture components 5 contact the inner wall of the crucible through the first rubber pad 12 and the second rubber pad 15, preventing the surface of the single-hole crucible 17 from being scratched. Moreover, the contact surfaces of the first rubber pad 12 and the second rubber pad 15 with the crucible are arranged with patterns, thereby increasing the frictional force and preventing the crucible from falling off during hoisting. The safety during the operation is relatively high. This application has a simple structure, is easy to use, and has strong practicability.

[0019] Embodiment 2, based on embodiment 1, specifically, when the present application is used, a set of clamp components 5 can be as shown in the accompanying drawings of the specification. Figures 1-4 The clamp 5 is shown to clamp a single-hole crucible 17. Each set of clamp components 5 includes a first gusset plate 11 and a second gusset plate 14, wherein a first counterweight body 13 is arranged on the first gusset plate 11. Under the gravity of the first counterweight body 13, the first gusset plate 11 naturally has a certain flip angle, thereby making the first rubber pad 12 face away from the axis of the vertical shaft 1, so that during the hoisting process, the first rubber pad 12 can be as shown in the drawings of the specification. Figure 1 The second gusset plate 14 is fitted with the inner wall of the single-hole crucible 17; at the same time, a second counterweight 16 is arranged on the second gusset plate 14. Under the gravity of the second counterweight 16, the second gusset plate 14 naturally has a certain flip angle, so that the second rubber pad 15 is oriented toward the direction close to the axis of the vertical shaft 1, so that during the hoisting process, the second rubber pad 15 can be as shown in the drawings of the specification. Figure 1 The inner wall of the single-hole crucible 17 is fitted.

[0020] During the lifting process, the lifting ear 2 is connected to the hook of the external lifting equipment, and each clamp assembly 5 is extended into the corresponding single-hole crucible 17. As the lifting equipment is lifted upward through the lifting ear 2, the vertical shaft 1 will move upward accordingly. During the upward movement of the vertical shaft 1, it will slide relative to the mounting sleeve 4 and act on the inner support rod 8 through the mounting seat 3, and the inner support rod 8 will act on the outer support rod 6, and then the inner support rod 8 and the outer support rod 6 will move accordingly, so that the outer support rod 6 will be stretched outward (i.e., away from the axis of the vertical shaft 1), and then the first fastener 7 will also abut against one side of the inner wall of the single-hole crucible 17, and the connecting rod 9 fixedly connected to the inner support rod 8 will be stretched inward (i.e., close to the axis of the vertical shaft 1), and then the second fastener 10 will also move accordingly as shown in the drawings in the specification. Figures 1-4 As shown, it abuts against the other side of the inner wall of the single-hole crucible 17, and as the upward hoisting proceeds, the first fastener 7 and the second fastener 10 are tightly abutted against the inner wall of the single-hole crucible 17, and the deadweight of the single-hole crucible 17 is cooperated, so that the clamp assembly 5 completes the stable clamping of the single-hole crucible 17, and the hoisting operation of the single-hole crucible 17 can be completed safely and efficiently.
