Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production and processing, in particular to an anti-dropping device for an electrolytic aluminum small box clamp. Background Art

[0002] In the process of aluminum electrolysis production, a small box clamp is needed. The function of the small box clamp is to clamp the aluminum guide rod with a carbon block anode to the large busbar. Every time a new anode is replaced, the screw head component will open the small box clamp and pull out the old anode. After the new anode is replaced, the screw head component will clamp the small box clamp and fix the anode to the large busbar. When the screw head component opens the small box clamp, the arc plate of the small box clamp will be hung on the hanging plate of the screw head component, and the small box clamp will rise and fall with the screw head component. During the operation of the aluminum electrolysis multifunctional overhead crane, the small box clamp may fall due to vibration or non-standard size of the small box clamp, which may easily injure the staff under the overhead crane. This happens frequently in aluminum electrolysis plants and poses a safety hazard. To this end, we propose an anti-drop device for the small box clamp of electrolytic aluminum. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example 1

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: an anti-dropping device for an electrolytic aluminum small box clamp, comprising an assembly frame 1, the assembly frame 1 is composed of two L-shaped plates 11 arranged opposite to each other and a vertical frame 12 located between the two plates 11, the vertical frame 12 is welded and fixed between the two plates 11, and the outer side walls of the two plates 11 are respectively welded and fixed with support arms 13, and the support arms 13 are used for installing and fixing a first insulator 14.

[0022] An anti-slip frame 2 is rotatably connected to the bottom of the vertical frame 12, and a driving mechanism 3 is installed between the assembly frame 1 and the anti-slip frame 2. The anti-slip frame 2 can be driven by the driving mechanism 3 to move. When the small box clamp moves up and down, the anti-slip frame 2 can protect the bottom of the small box clamp to prevent the small box clamp from falling off during the rising or falling process.

[0023] like Figure 1 and Figure 3 As shown in the figure, the middle part of the anti-slip frame 2 is rotatably connected to the bottom of the vertical frame body 12 via a rotating shaft, one end of the anti-slip frame 2 is fixedly equipped with a second insulator 21, and the second insulator 21 is used to fit with the bottom of the small box fixture during the anti-slip process, and the other end of the anti-slip frame 2 is welded and fixed with a fixed shaft 22, and the fixed shaft 22 is used to connect with the driving mechanism 3, so that the driving mechanism 3 can drive the anti-slip frame 2 to rotate at the connection with the vertical frame body 12.

[0024] The first insulator 14 and the second insulator 21 are provided to protect the electronic components in the device, thereby preventing the small box fixture from being electrified and causing damage to the electronic components in the device.

[0025] like Figure 1 and Figure 2 As shown in the figure, the driving mechanism 3 includes an electric push rod 31, which is fixedly assembled in the assembly frame 1. The electric push rod 31 is electrically connected to an external power supply and an external controller. The output end of the electric push rod 31 can be controlled by the external controller to perform up and down movements. The output end of the electric push rod 31 is fixedly connected to a connecting sleeve 32, and the connecting sleeve 32 is sleeved on the outer side wall of the fixed shaft 22. The fixed shaft 22 can rotate in the connecting sleeve 32. The action of the output end of the electric push rod 31 can drive the anti-slip frame 2 to rotate to adjust the angle.

[0026] The driving mechanism 3 also includes a first connecting arm 33 and a second connecting arm 34, and the number of the first connecting arm 33 and the second connecting arm 34 are respectively two. The two first connecting arms 33 and the second connecting arms 34 are relatively distributed with the assembly frame 1 as the center. One end of the first connecting arm 33 is hinged to the side wall of the assembly frame 1, the other end of the first connecting arm 33 is hinged to one end of the second connecting arm 34, and the other end of the second connecting arm 34 is hinged to the outer side wall of the anti-stripping frame 2. The first connecting arm 33, the second connecting arm 34, the vertical frame 12 and the anti-stripping frame 2 form a parallelogram connecting rod mechanism, thereby increasing the stability of the electric push rod 31 in the process of driving the anti-stripping frame 2 to rotate, and also increasing the bearing capacity of the anti-stripping frame 2, avoiding deformation between the anti-stripping frame 2 and the vertical frame 12 after the small box clamp falls off, thereby affecting the effect of its angular position adjustment.

[0027] like Figure 1 and Figure 2 As shown in the figure, a screwing mechanism 5 is fixedly installed on the top of the assembly frame 1. The screwing mechanism 5 is used in conjunction with the present device to drive the bidirectional screw in the small box fixture to move, thereby completing the opening and closing of the small box fixture. The screwing mechanism 5 includes a connecting frame 51, and a screwing sleeve 52 is rotatably connected to the connecting frame 51. The screwing sleeve 52 is used to be clamped with the top of the bidirectional screw in the small box fixture. The small box fixture can be opened or closed by driving the bidirectional screw with the screwing sleeve 52. The end of the connecting frame 51 is rotatably connected to a guide roller 53. By setting the guide roller 53 to fit mutually with the beam body of the clamped small box fixture, the lifting position of the connecting frame 51 can be limited to ensure the accuracy of the docking position between the screwing sleeve 52 and the bidirectional screw.

[0028] The end of the connecting frame 51 is equipped with a vertically arranged guide frame 54, and an arc groove 55 is provided at the bottom of the guide frame 54. By adding the guide frame 54, the docking convenience between the device and the small box clamp during the connection process is effectively improved, and the accuracy of the docking position is improved.

[0029] In the above-mentioned process of controlling the rotation of the anti-slip frame 2 by the electric push rod 31, it is necessary to synchronize the start of the electric push rod 31 with the screwing of the shaft sleeve 52 and the two-way screw in the small box clamp. It is only necessary to set the stroke speed of the electric push rod 31. In this way, there is no need to add extra buttons to the cab or remote control of the aluminum electrolysis multifunctional overhead crane, and the operation is no different from the previous operation.

[0030] Working principle: Figure 1 , Figure 4 and Figure 5 As shown in FIG, during the use of the device, the initial state of the anti-drop frame 2 is as follows Figure 1 As shown in the figure, in the process of driving the assembly frame 1 and the anti-slip frame 2 to descend by the external lifting equipment, the anti-slip frame 2 leaves a space for the small box clamp to enter the screw head mechanism 5. As the assembly frame 1 descends, the screwing sleeve 52 is smoothly docked with the top of the bidirectional screw in the small box clamp through the cooperation of the guide frame 54 and the guide roller 53. The screwing sleeve 52 is controlled to rotate by the external transmission rod. While the screwing sleeve 52 rotates the bidirectional screw to open the small box clamp, the output end of the electric push rod 31 can be controlled to move synchronously. The output end of the electric push rod 31 drives the anti-slip frame 2 to rotate downward, so that the anti-slip frame 2 rotates to the position shown in the figure. Figure 5 At the angle position shown in the figure, in the subsequent process of the small box clamp being driven to rise in position by the screw head mechanism 5, the anti-fall-off frame 2 can fully protect the small box clamp to prevent the small box clamp from falling off at a high altitude and causing a safety accident.

[0031] Example 2

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution which is different from the technical solution in the first embodiment in that an auxiliary anti-slip component 4 is fixedly installed between the end of the first connecting arm 33 and the assembly frame 1, such as Figure 2 and Figure 3 As shown in the figure, the auxiliary anti-slip assembly 4 includes a fixing plate 41, which is welded and fixed to the side wall of the assembly frame 1, and a guide cylinder 42 arranged opposite to each other is integrally formed in the fixing plate 41, and a steel wire rope 43 passes through the guide cylinder 42, one end of the steel wire rope 43 is clamped and fixed to the end of the first connecting arm 33 by a buckle 44, and the other end of the steel wire rope 43 is fixedly connected to a limiting clamp block 45.

[0033] like Figure 1 , Figure 2 and Figure 5As shown in the figure, when the first connecting arm 33 follows the second connecting arm 34 to rotate and adjust the position, the moving stroke of the wire rope 43 can be guided by the guide cylinder 42, and the end of the wire rope 43 with the limit block 45 is inserted into the interior of the small box clamp, so that when the subsequent small box clamp rises, the small box clamp can be prevented from falling off through the cooperation of the limit block 45 and the anti-fall-off frame 2. The double anti-fall-off method is adopted, so that the device has a better anti-fall-off effect during use.
