A hook is fixed on the top of the suspension rod, and the bottom end of the suspension rod is hinged with the center of the top surface of the fixed plate; a plurality of upper wing plates are arranged in parallel above the fixed plate, and one end of the upper wing plate is rotatably connected with the upper part of the suspension rod; a plurality of long holes arranged along the radial direction of the suspension rod are opened on the upper wing plate, and a connecting rod is arranged between each upper wing plate and the lower fixed plate, and the top end of the connecting rod is slidably arranged in the long hole, and the bottom end of the connecting rod is hinged with the fixed plate. Advantages: the upper wing plate is a reference plane parallel to the ground.

No manual participation is required during the hoisting process, which improves safety.

Description

Technical field:

[0001] The utility model relates to the technical field of electrode hoisting, in particular to a graphite electrode hoisting auxiliary device. Background technology:

[0002] The common hoisting of graphite electrodes is to use a clamping device to clamp the outer circle of the electrode to achieve hoisting. This hoisting method is suitable for situations where the space around the electrode is large. For situations where the space around the electrode is small, such as the graphite electrode on the electrolytic cell is clamped in the brake during use, and the surrounding space is small. When the graphite electrode breaks, the broken electrode will fall into the electrolytic cell under the brake. At this time, due to the limitation of the brake, the space around the broken graphite electrode is small, and the form of clamping the outer circle of the electrode is no longer applicable. Instead, it is necessary to fix the wire rope with bolts on the top of the residual graphite electrode, and then pass the top of the wire rope through the brake and connect it to the hoisting equipment. However, since the broken graphite electrode is not an ideal cylinder, its mass distribution is uneven, and it is easy to be eccentric during the hoisting process, and the electrode hits the clamp, which is easy to cause damage to the clamp; there is also a situation where the electrode is stuck in the clamp, and the electrode needs to be pushed manually to complete the electrode hoisting. The risk of electrode falling or shaking cannot be completely avoided during the process, and there is a great safety hazard. Utility model content:

[0003] The utility model aims to provide a graphite electrode hoisting auxiliary device.

[0004] The utility model is implemented by the following technical scheme: a graphite electrode lifting auxiliary device, which includes a fixed plate, a suspension rod, an upper wing plate and a connecting rod, a hook is fixed on the top end of the suspension rod, the bottom end of the suspension rod is hinged to the center of the top surface of the fixed plate, a plurality of through holes are opened on the fixed plate, and bolts screwed to the graphite electrode are arranged in the through holes; a plurality of upper wing plates are arranged in parallel above the fixed plate, one end of the upper wing plate is rotatably connected to the upper part of the suspension rod; a plurality of long holes arranged radially along the suspension rod are opened on the upper wing plate, a connecting rod is arranged between each upper wing plate and the fixed plate below, the top end of the connecting rod is slidably arranged in the long hole, and the bottom end of the connecting rod is hinged to the fixed plate.

[0005] Furthermore, a sliding block is fixed on the top end of the connecting rod and slides along the corresponding long hole.

[0006] Furthermore, an articulated seat is fixed at the center of the top surface of the fixed plate, a spherical bearing is rotatably connected inside the articulated seat, and the bottom end of the suspension rod is arranged inside the spherical bearing.

[0007] The utility model has the following advantages: the wing plate is a reference plane parallel to the ground, and when the graphite electrode is eccentric, the light side of the electrode is prevented from floating up by the connecting rod inclined at a large angle, and the heavy side of the electrode is prevented from sinking by the connecting rod inclined at a small angle, thereby controlling the inclination of the electrode, preventing the electrode from colliding with or getting stuck with the brake, and allowing the electrode to be hoisted out smoothly. No human intervention is required during the hoisting process, thereby improving the safety of the operation. Description of the drawings:

[0011] In the description of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0012] like Figure 1 and Figure 2 As shown, the graphite electrode hoisting auxiliary device comprises a fixed plate 1, a suspension rod 2, an upper wing plate 3 and a connecting rod 4. A hook 5 is fixed at the top of the suspension rod 2, and the hook 5 is used to connect with the hook of the hoisting equipment. The bottom end of the suspension rod 2 is hinged with the center of the top surface of the fixed plate 1. Specifically, a hinge seat 6 is fixed at the center of the top surface of the fixed plate 1. A joint bearing 7 is rotatably connected in the hinge seat 6, and the bottom end of the suspension rod 2 is arranged inside the joint bearing 7. A plurality of through holes are provided on the fixed plate 1, and bolts 10 screwed to the graphite electrode 9 are arranged in the through holes; three upper wing plates 3 are arranged in parallel above the fixed plate 1, and one end of the upper wing plate 3 is rotatably connected to the upper part of the suspension rod 2; a plurality of long holes 11 arranged along the radial direction of the suspension rod 2 are provided on the upper wing plate 3, and a connecting rod 4 is arranged between each upper wing plate 3 and the fixed plate 1 below, and the top end of the connecting rod 4 is slidably arranged in the long hole 11 through a slider 12, and the bottom end of the connecting rod 4 is hinged with the fixed plate 1.

[0013] Working principle: Through the joint bearing 7, the fixed plate 1 fixed on the graphite electrode 9 can be tilted at a certain angle to the suspension rod 2, so as to achieve a smooth connection between the graphite electrode 9 with an inclined fracture surface and the fixed plate 1. The upper wing plate 3 is always perpendicular to the suspension rod 2. During the hoisting process of the graphite electrode 9, the distance between the upper wing plate 3 and the fixed plate 1 becomes different with the inclination of the graphite electrode 9 and the fixed plate 1; during hoisting, the fixed plate 1 will sink with the heavy side of the graphite electrode 9 and rise with the light side, so that the upper wing plate 3 tends to be parallel to the ground. By installing a connecting rod 4 between the upper wing plate 3 and the electrode fixing plate 1, the distance between the upper wing plate 3 and the fixed plate 1 can be controlled by sliding the slider 12 (fixable position) in the long hole 11, so that the distance between the upper wing plate 3 and the fixed plate 1 is fixed.

[0014] The above wing plate 3 is a reference plane parallel to the ground. When the graphite electrode 9 is eccentric, the light side of the graphite electrode 9 is prevented from floating up by the connecting rod 4 inclined at a large angle, and the heavy side of the graphite electrode 9 is prevented from sinking by the connecting rod 4 inclined at a small angle, thereby achieving the purpose of controlling the inclination of the graphite electrode 9, preventing the electrode from colliding with or getting stuck with the brake, and allowing the electrode to be hoisted out smoothly. No human intervention is required during the hoisting process, thereby improving the safety of the operation.

[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
