[0002] During the sintering process of lithium battery positive electrode material manufacturing, the inside of the furnace, front and rear replacement chambers and other confined spaces may drop box fragments or other dropped objects in the equipment that affect production safety and quality, causing the kiln transmission system to get stuck, affecting the normal progress of the entire production process, and easily causing production safety accidents, affecting product quality and reducing production efficiency. Therefore, it is necessary to stop the equipment urgently, clean up the dropped objects in time, ensure the normal operation of the kiln transmission system, and achieve the purpose of ensuring production efficiency.

[0003] In the prior art, when performing cleaning operations, due to limited operating space, the internal temperature of the working space can reach as high as 200°C, and the working environment contains a large amount of nitrogen and other harmful gases. Personnel cannot directly enter the interior to remove dropped objects, so operators are required to use clamps for manual cleaning. That is, after the transmission device is manually stopped due to the jamming of dropped objects, the operator holds the clamp and reaches into the equipment from the side inspection port, finds the location where the dropped object is stuck, and uses the clamp to clamp out the dropped object.

[0004] This cleaning method has the following disadvantages: 1. There are serious safety hazards such as burns and suffocation caused by nitrogen; 2. The field of vision in the working space is limited and the situation is complicated, so the operators cannot accurately choose the corresponding labor protection supplies; 3.

Cleaning up the dropped objects each time is time-consuming and labor-intensive, which will bring additional labor costs to the company and reduce production efficiency.

[0005] To this end, this paper provides an automated fixture for confined spaces. Utility Model Content

[0047] The working principle of the utility model is as follows: the automatic clamp 3 is inserted into the equipment space where the dropped objects need to be cleaned by holding the clamp handle 1, and then the control button 8 on the clamp handle 1 is pressed to control the telescopic rod drive motor 6, and the telescopic drive motor 6 drives the coupling a7, and then transmits the power to the active rod 12 in the automatic telescopic connecting rod 2, and the active rod 12 drives the driven rod 13 to move along the rod thread direction, and the driven rod 13 drives the outer small sleeve 16 to move along the rod direction in the large sleeve 15, so as to complete the extension and shortening of the device;

[0049] After finding the location of the dropped object by controlling the automatic telescopic connecting rod 2 and observing the image data on the display screen 9, the trigger 10 under the clamp handle 1 is pressed, and the control power and measurement and control module in the line transmission signal control start the chuck drive motor 20, drive the coupling b21 at the front end of the chuck drive motor 20, and transmit power to the bevel gear transmission group 26 at the front end of the coupling b21. The bevel gear transmission group 26 converts the power along the rod direction into the power in the vertical rod direction, and then drives the inclined cam crank rocker mechanism 27 to convert the power in the vertical and rod directions into the power based on the swing at one point on the same horizontal plane as the rod, driving the long power arm 28 to open and close; so that the entire clamp arm 30 can work normally. After clamping the dropped object, the two short follower arms 29 will clamp the dropped object with the same force as the torsion spring 30 in the closing direction of the long power arm 28, and the tooth pattern 31 on the clamp arm allows the clamp arm to better clamp the dropped object;

[0050] At the same time, the weighing sensor 19 will transmit the weight signal of the falling object to the processor 5, which will then be converted into an image signal and transmitted to the display screen 9;

[0051] Finally, the operator presses the control button 8 on the clamp handle 1 to control the contraction of the automatic telescopic connecting rod 2 based on the same principle as above, so as to clamp the fallen objects out of the equipment and complete the cleaning operation.
