For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] See also Figure 1-Figure 3As shown, the auxiliary equipment for welding inside the fume hood described in this embodiment includes a long ladder 1, a short ladder 2, a winding structure 3 and a cable 4. The top of the long ladder 1 is provided with a hanging hook lock 5 for hooking and locking with an external overhead crane to hang and fix the long ladder 1. The winding structure 3 is rotatably arranged at the top of the long ladder 1. The cable 4 is arranged on the winding structure 3. The short ladder 2 is arranged near the bottom end of the long ladder 1 to provide a working area. The short ladder 2 is connected to the cable 4 so that the position of the short ladder 2 relative to the long ladder 1 can be adjusted by the length of the cable 4.

[0028] The present embodiment has a simple structure and a reasonable design. The long ladder 1 and the short ladder 2 are combined to assist the downward movement. At the same time, the angle of the hanging long ladder 1 is adjusted to provide a working area for the operators. The operators work on the short ladder 2, which makes it convenient for the operators to work on the short ladder 2 and repair the smoke hood.

[0029] In some embodiments, the winding structure 3 is provided with a winding drum 31 and a rotating shaft 32 . The rotating shaft 32 is rotatably arranged at the top of the long ladder 1 , and the rotating shaft 32 is connected to a crank 33 . The winding drum 31 is installed on the rotating shaft 32 .

[0030] Specifically, a limit bolt 11 is provided at a position of the ladder 1 close to the crank 33 .

[0031] The winding structure 3 is specifically shown in the present embodiment. When in use, the length of the cable 4 is adjusted by turning the crank 33, so that the lowering distance of the short ladder 2 is controlled by the cable 4. Then the staff stands on the short ladder 2, and the overhead crane lifts the entire device and begins to lower it into the smoke hood. When the device is lowered to the specified position, it stops. If the device is not properly arranged, the overhead crane hook lock can be used to move up and down and rotate the device to adjust the position. The inside of the smoke hood can be repaired in all directions. The angle is determined by the working space, and the adjustment is very convenient.

[0032] In some embodiments, an angle adjusting member 6 is provided on a side of the short ladder 2 close to the long ladder 1 , one end of the angle adjusting member 6 is movably hinged to the short ladder 2 , and the other end is in contact with the long ladder 1 .

[0033] Specifically, a roller 61 is provided at one end of the angle adjusting member 6 that abuts against the long ladder 1 .

[0034] More specifically, the angle adjustment range of the angle adjustment member 6 is set to 0°-90°.

[0035] The present embodiment specifically shows that an angle adjustment member 6 is provided between the short ladder 2 and the long ladder 1 for adjusting the angle therebetween. Thus, on the basis of adjusting the angle of the long ladder 1 by hanging the overhead crane, the angle between the short ladder 2 and the long ladder 1 is adjusted by the angle adjustment member 6, so that the angle can be flexibly adjusted to a suitable working angle for the convenience of operation by the staff.

[0036] At the same time, since one end of the angle adjustment member 6 that abuts the long ladder 1 is provided with a roller 61, the smoothness of the downward process can be improved; specifically, in this embodiment, a number of adjustment slots can be set on the short ladder 2, and the angle adjustment member 6 is first adjusted to a suitable angle, and then fixed by means of a latch or the like, and the roller 61 of the angle adjustment member 6 is made to abut against the long ladder 1 to achieve flexible angle adjustment.

[0037] Specifically, the length of the long ladder 1 is set to be twice that of the short ladder 2 .

[0038] In this embodiment, by setting the long ladder 1 to be twice the length of the short ladder 2, it is convenient for lowering operation, and at the same time, the length difference is not too large, so as to ensure the safety of use.

[0039] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
