Description

Technical Field

[0001] This utility model relates to the field of overhead crane wrench technology, specifically to a precise alignment device for overhead crane wrenches. Background Technology

[0002] In heavy industries such as electrolytic aluminum and steel smelting, overhead crane wrenches are responsible for the bolt assembly and disassembly of key components such as anode mechanisms and heavy equipment connectors. During the bolt assembly and disassembly process, the wrench head needs to be aligned and connected with the anode mechanism.

[0003] The currently commonly used manual alignment method lacks a reliable positioning benchmark, which easily leads to misalignment between the wrench head and the bolt holes of the anode mechanism, resulting in loose equipment connections, wear of structural components, and other malfunctions. The auxiliary positioning fixture uses tension springs for alignment, but the elasticity of the tension springs decreases significantly after long-term use, making it difficult to meet the needs of high-intensity maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a precise alignment device for overhead crane wrenches, in which a tension spring is replaced by a compression spring structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crane wrench precision alignment device, including a wrench base, a wrench head provided on the top of the wrench base, the wrench base and the wrench head together forming a wrench structure, the wrench structure being used in conjunction with the anode mechanism body, the anode mechanism body being connected to the electrolytic cell through an anode clamp.

[0006] Preferably, the surface of the base of the wrench is provided with an auxiliary alignment structure, which is connected to the main body of the anode mechanism through a first steel plate and a second steel plate.

[0007] By adopting the above technical solution, the auxiliary alignment structure can be used to assist in the alignment of the wrench structure with the main body of the anode mechanism.

[0008] Preferably, the auxiliary alignment structure includes a mounting groove, which is disposed through the side surface of the wrench base. The mounting groove is a cuboid structure. A No. 1 steel plate is slidably mounted on the inner wall of the mounting groove. A circular through hole is disposed through the surface of the No. 1 steel plate. One end of the No. 1 steel plate is fixed to the surface of the connecting spring, and the other end of the connecting spring is fixed to the inner wall of the mounting groove.

[0009] By adopting the above technical solution, the connecting spring and the No. 1 steel plate can be used to support and fix the fixing bolt.

[0010] Preferably, a second steel plate is arranged parallel to one side of the first steel plate, and a threaded hole is provided through the surface of the second steel plate.

[0011] By adopting the above technical solution, the No. 2 steel plate can be used to achieve contact guidance for the main body of the anode mechanism.

[0012] Preferably, the threaded hole on the surface of the second steel plate is threadedly connected to the surface of the fixing bolt, and the other end of the fixing bolt passes through the circular through hole on the surface of the first steel plate and slides through the surface of the mounting groove. The outer surface of the fixing bolt is threadedly connected to a nut, and the nut is rotatably mounted on the surface of the wrench base.

[0013] Using the above technical solution, the position of the fixing bolt can be fixed by using a nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the precise alignment device for the overhead crane wrench:

[0015] 1. In this device, steel plates No. 1 and No. 2 are set at the base of the wrench to assist the wrench structure in aligning with the main body of the anode mechanism. This improves the accuracy of the connection between the overhead crane wrench and the main body of the anode mechanism, reduces operational errors caused by misalignment, and ensures that the wrench head can accurately act on the target position on the main body of the anode mechanism, thereby improving work efficiency and operational reliability.

[0016] 2. The No. 1 steel plate in this device is slidably installed between itself and the mounting groove, and a connecting spring is installed inside the mounting groove to connect with the No. 1 steel plate. During the alignment process, the No. 1 steel plate will drive the connecting spring to compress. Compared with the tension spring, the compressed connecting spring can prevent the connecting spring from elastic fatigue, deformation and breakage due to long-term operation, ensuring the accuracy of the wrench structure alignment and increasing the maintenance strength.

[0017] 3. In this device, a threaded hole is provided on the surface of the No. 2 steel plate to cooperate with the fixing bolt. The other end of the fixing bolt passes through the circular through hole on the surface of the No. 1 steel plate and slides through the mounting groove. It is fixed by the nut. When it is necessary to replace or repair the auxiliary alignment structure, the nut can be easily unscrewed, the fixing bolt can be removed, and the No. 1 steel plate, the No. 2 steel plate or the connecting spring and other components can be replaced or maintained.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a crane wrench precision alignment device, including a wrench base 1, an anode mechanism body 2, an anode clamp 3, a wrench head 4, a mounting groove 5, a first steel plate 6, a connecting spring 7, a second steel plate 8, a fixing bolt 9, and a nut 10.

[0026] A wrench head 4 is provided at the top of the wrench base 1. The wrench base 1 and the wrench head 4 together constitute the wrench structure. The wrench structure is used to dock with the anode mechanism body 2. The anode mechanism body 2 is connected to the electrolytic cell through the anode clamp 3. An auxiliary alignment structure is provided on the surface of the wrench base 1. The auxiliary alignment structure assists the wrench structure in aligning with the anode mechanism body 2 through a first steel plate 6 and a second steel plate 8. The auxiliary alignment structure includes a mounting groove 5, which is provided through the side surface of the wrench base 1. The mounting groove 5 is a cuboid structure, and a first steel plate 6 is slidably installed on the inner wall of the mounting groove 5. A circular through hole is provided through the surface of the No. 1 steel plate 6. The surface of the No. 1 steel plate 6 is fixed to one end of the connecting spring 7. The other end of the connecting spring 7 is fixed to the inner wall of the mounting groove 5. A No. 2 steel plate 8 is arranged parallel to one side of the No. 1 steel plate 6. A threaded hole is provided through the surface of the No. 2 steel plate 8. The threaded hole on the surface of the No. 2 steel plate 8 is threadedly connected to the surface of the fixing bolt 9. The other end of the fixing bolt 9 passes through the circular through hole on the surface of the No. 1 steel plate 6 and slides through the surface of the mounting groove 5. A nut 10 is threadedly connected to the outer surface of the fixing bolt 9. The nut 10 is rotatably mounted on the surface of the wrench base 1.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, during the alignment process using this device with the anode mechanism body 2, the anode mechanism body 2 is connected to the electrolytic cell via the anode clamp 3. During use, the wrench head 4 is used to tighten or loosen the relevant components on the anode mechanism body 2. Depending on the position of the anode mechanism body 2, the second steel plate 8 is placed against the surface of the anode mechanism body 2. The nut 10 on the surface of the wrench base 1 is rotated, causing the fixing bolt 9 to adjust its length on the surface of the wrench base 1 as the nut 10 rotates. The fixing bolt 9 passes through the mounting groove 5 and the surface of the first steel plate 6. Therefore, the fixing bolt 9 will drive the wrench base 1 and the first steel plate 6 to move, so that the first steel plate 6 is close to the second steel plate 8. During this process, the wrench base 1 drives the wrench head 4 on the surface to approach the alignment part of the anode mechanism body 2, and continuously rotates the nut 10. After the first steel plate 6 contacts the second steel plate 8, it slides into the interior of the mounting groove 5 under the action of the second steel plate 8, and compresses the internal connecting spring 7. Through the approaching first steel plate 6 and second steel plate 8, the wrench head 4 is aligned with the operating part of the anode mechanism body 2 to perform tightening or loosening operations.

[0028] Working principle: When using the crane wrench precision alignment device, the No. 2 steel plate 8 is placed against the surface of the anode mechanism body 2. The nut 10 is rotated, and the rotating nut 10 causes the fixing bolt 9 to move on the surface of the wrench base 1, thereby moving the No. 1 steel plate 6 closer to the No. 2 steel plate 8. During this process, the wrench base 1 and the wrench head 4 simultaneously approach the part of the anode mechanism body 2 that needs to be tightened or loosened. As the No. 1 steel plate 6 and the No. 2 steel plate 8 approach each other, the No. 1 steel plate 6 compresses the connecting spring 7 inside the mounting groove 5. At this time, the wrench head 4 engages with the part of the anode mechanism body 2 that needs to be operated, and normal tightening or loosening operations are performed, increasing the overall practicality.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
