Description

Technical Field

[0001] The present invention relates to the technical field of aluminum electrolysis industry, and more specifically to a connecting device between a shelling cylinder and a pull rope sensor. Background Art

[0002] At present, the connection between the shelling cylinder and the wire displacement sensor in the aluminum electrolysis industry is fixed by aluminum buckles. The connection operation is manual, and the buckling pressure of the aluminum buckle is not easy to control. If the buckling pressure is too small, it is easy to cause the aluminum buckle to fall off, and if the buckling pressure is too large, it is easy to damage and break the steel wire. Therefore, it is often necessary to replace the wire displacement sensor frequently. During the frequent replacement process, the fixing threaded hole of the aluminum buckle is easily damaged, making the aluminum buckle not firmly fixed, causing air leakage, and making the wire displacement sensor unable to operate normally, thereby reducing production efficiency and increasing production costs and labor intensity.

[0003] In summary, how to improve the connection effect between the shell breaking cylinder and the wire displacement sensor is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0029] In actual use, the shape, structure, size, material, position, etc. of the fixing plate 1, the wire assembly 2, the connector 3 and the elastic member 4 can be determined according to actual conditions and actual needs.

[0030] When using the connection device of the shell breaking cylinder and the pull rope sensor provided by the present invention, first, the fixed disk 1 and the piston rod 5 can be connected, and the elastic member 4 can be placed in the fixed disk 1. After that, the wire assembly 2 and the sensor assembly 16 can be connected, and the wire assembly 2 can be placed in the connector 3. Then, the connector 3 can be inserted into the fixed disk 1. At this time, the protrusion 6 of the connector 3 can be passed through the slot 7 to ensure that the connector 3 is smoothly inserted into the fixed disk 1 and the connector 3 and the elastic member 4 are abutted.

The operation process is simple and convenient, which can ensure that the piston rod 5 and the sensor assembly 16 run synchronously and are effectively connected.

[0031] In summary, the connecting device between the shell breaking cylinder and the pull-wire displacement sensor provided by the present invention can effectively improve the connection effect between the shell breaking cylinder and the pull-wire displacement sensor.

[0032] Based on the above embodiment, preferably, the fixing plate 1 is made of aluminum alloy, which has good processing performance and can improve processing efficiency.

[0033] Preferably, the surface of the fixing plate 1 is an anti-oxidation surface that has been anodized to improve the anti-oxidation property of the fixing plate 1 and to improve the service life and use effect of the fixing plate 1 .

[0034] Preferably, a buffer spring 8 and a bearing 9 are provided between the steel wire assembly 2 and the connector 3. Because the piston rod 5 rotates left and right and drives the steel wire assembly 2 to rotate, the steel wire assembly 2 becomes loose and breaks. In order to synchronize the steel wire assembly 2 with the cylinder and the piston rod 5, a bearing 9 is added between the connector 3 and the steel wire assembly 2 to ensure that the steel wire assembly 2 and the piston rod 5 rotate at the same time.

[0035] Preferably, the buffer spring 8 is a flat-end-to-top wave spring, and a positioning sleeve 10 is provided between the flat-end-to-top wave spring and the bearing 9.

[0036] It should be noted that, in order to improve the reliability and service life of the steel wire assembly 2, a buffer spring 8 can be added between the steel wire assembly 2 and the connector 3 to play a buffering role. Considering the compactness of the device structure and the spring travel problem, in order to ensure the accuracy of data collection, a flat-end to top wave spring with advanced structure is preferred. In order to ensure the buffering effect of the flat-end to top wave spring and the smooth rotation of the bearing 9, a positioning sleeve 10 can be installed between the flat-end to top wave spring and the bearing 9.

[0037] On the basis of the above embodiment, preferably, the steel wire assembly 2 includes a cylinder 11 disposed in the connecting body 3 and a steel wire piece 12 for connecting the cylinder 11 and the sensor assembly 16 .

[0038] Preferably, the steel wire piece 12 is a stainless steel wire coated with a nylon piece on the outside, so that the steel wire piece 12 can be retracted and released more smoothly, thereby improving the use effect and service life of the steel wire piece 12.

[0039] Preferably, the cylinder 11 and the wire piece 12 are an integrated structure. The wire piece 12 and the cylinder 11 can be buckled into the wire assembly 2 using an advanced molding process to keep the buckling force consistent and greatly reduce damage to the wire piece 12 at a force that meets the process requirements.

[0040] Preferably, protrusions 6 are correspondingly provided on both sides of the connecting body 3, and two recesses are correspondingly provided on the inner wall of the groove 7.

[0041] It should be noted that the connector 3 and the fixed disk 1 are fixed by means of protrusions 6 and grooves, that is, an insert-type snap-fit ​​structure is used for the connection operation, which can ensure the connection reliability of the connector 3 and the fixed disk 1, and also make the connection operation more convenient and reliable, ensuring that the wire assembly 2 will not move up and down, thereby ensuring the accuracy of data collection.

[0042] Preferably, the elastic member 4 includes a compression spring 13 , a spring sleeve 14 for defining a moving trajectory of the compression spring 13 , and a spring seat 15 for supporting the compression spring 13 .

[0043] In order to further illustrate the connection device between the shell breaking cylinder and the pull rope sensor provided by the present invention, an example is given below.

[0044] First, the bearing 9, the positioning sleeve 10, the flat-end top-to-top wave spring and the wire assembly 2 can be sequentially installed into the connector 3 to form a component, such as Figure 3 Then, the spring sleeve 14, the compression spring 13, and the spring seat 15 are sequentially installed into the fixed disk 1 to form another component, such as Figure 4As shown. During installation, the fixed disk 1 can be fixed on the piston rod 5 by the retaining ring, and then the protrusions 6 on both sides of the connector 3 are aligned with the slots 7 of the fixed disk 1 and pressed down, so that the spring seat 15 moves down and the compression spring 13 can be compressed. After the connector 3 is installed in place, the connector 3 is rotated 90 degrees to the left and the downward pressure is released, and the compression spring 13 rebounds upward, so that the protrusion 6 of the connector 3 enters the depression in the fixed disk 1. When the sensor assembly 16 needs to be replaced, the connector 3 can be pressed down with a tool to move the spring seat 15 downward and compress the compression spring 13. When the connector is moved into place, the connector is rotated 90 degrees to the right and the downward pressure is released, and the compression spring 13 rebounds upward, so that the connector 3 can be taken out easily.

[0045] In addition, it should be noted that the directions or positional relationships indicated by "up and down", "left and right", etc. in this application are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
