[0026] The embodiment of the present application provides a suspension device that can be used for a two-protection welding machine. The positions of the welding handle wire and the carbon dioxide gas delivery pipe are rearranged to prevent the welding handle wire and the carbon dioxide gas delivery pipe from dragging on the ground, and to prevent operators from being tripped by the welding handle wire and the carbon dioxide gas delivery pipe. In addition, the construction and operation of this suspension device is simple and convenient, the work efficiency is high, and the cost is low.

Sometimes, it is even necessary to adjust the position of the workpiece and the station frame to arrange the welding handle wire and the gas pipe to a position suitable for the welder to operate, which is labor-intensive and time-consuming.

[0027] The following is a detailed description of a suspension device for a two-protection welding machine provided in this embodiment. Figure 1 As shown, the suspension device is arranged on a column 1 in a workshop, and mainly includes a first curved arm 2 and a second curved arm 4. The first curved arm 2 is connected to the column 1 through a first vertical twisted shaft 3; the second curved arm 4 is connected to the lower part of the free end of the first curved arm 2 through a second vertical twisted shaft 5; wherein, the first curved arm 2 and the second curved arm 4 are each provided with at least two suspension members 6 along the length direction, and the welding handle line 7 of the second-protection welding machine is suspended on the first curved arm 2 and the second curved arm 4 through the suspension member 6, and the welding trolley 8 is connected from the free end of the second curved arm 4.

[0028] In this embodiment, a first crank arm 2 and a second crank arm 4 are arranged on a column 1 in a workshop, so that the welding handle wire 7 of the two-guard welding machine can be hung on the first crank arm 2 and the second crank arm 4 through a hanging member 6, and the first crank arm 2 can swing a certain angle through the first vertical twisted shaft 3, and the second crank arm 4 can swing a certain angle through the second vertical twisted shaft 5, and the welding trolley 8 is installed on the free end of the second crank arm 4, so that the welding trolley 8 of the two-guard welding machine can be adjusted to a position above the welding station within the area where the total length of the first crank arm 2 and the second crank arm 4 is a radius, which is convenient to move, and the welding handle wire 7 is placed on the top of the first crank arm 2 and the second crank arm 4, and the welding handle wire 7 does not need to be worried about being stepped on or crushed, and the safety is better. This device greatly reduces the work intensity of workers, improves the work efficiency of workers, and effectively reduces costs.

[0029] Please refer to Figure 1 , Figure 2 As shown, in this embodiment, it should be noted that two first ear plates 11 are fixed on the side of the column 1, and the two first ear plates 11 are arranged opposite to each other up and down and at intervals, and the first vertical twisted shaft 3 is arranged between the two first ear plates 11 and rotates around its own axis. It can be understood that the upper end of the first vertical twisted shaft 3 is rotatably arranged on the first ear plate 11 located above, and the lower end of the first vertical twisted shaft 3 is rotatably arranged on the first ear plate 11 located below, and the fixed end of the first crank arm 2 is connected to the first vertical twisted shaft 3. Therefore, the first crank arm 2 can swing back and forth through the action of the first vertical twisted shaft 3.

[0030] In an achievable manner, the first crank arm 2 includes an upper crank arm rod 21, a lower crank arm rod 22 and a connecting rod 23, the upper crank arm rod 21 and the lower crank arm rod 22 are arranged parallel to each other, and a plurality of connecting rods 23 are arranged between the upper crank arm rod 21 and the lower crank arm rod 22, and are arranged at equal intervals along the length direction of the upper crank arm rod 21 and the lower crank arm rod 22, the upper end of the connecting rod 23 is connected to the upper crank arm rod 21, and the lower end of the connecting rod 23 is connected to the lower crank arm rod 22. It should be noted that the fixed ends of the upper crank arm rod 21 and the lower crank arm rod 22 are respectively connected to the side of the column 1 through the first vertical hinge shaft 3.

[0031] Please refer to Figure 1 , Figure 3 As shown, the free end of the lower crank arm 22 is fixed with two second ear plates 221, the two second ear plates 221 are arranged opposite to each other at intervals, the second vertical twisted shaft 5 is arranged between the two second ear plates 221, and is arranged to rotate around its own axis. It can be understood that the upper end of the second vertical twisted shaft 5 is rotatably arranged on the second ear plate 221 located above, the lower end of the second vertical twisted shaft 5 is rotatably arranged on the second ear plate 221 located below, and the fixed end of the second crank arm 4 is connected to the second vertical twisted shaft 5. Therefore, the second crank arm 4 can swing back and forth through the action of the second vertical twisted shaft 5.

[0032] The upper part of the free end of the second crank arm 4 is also connected to the upper part of the free end of the upper crank arm rod 21 through an obliquely pulled steel wire rope 101, thereby forming a right triangle between the second crank arm 4, the steel wire rope 101 and the free end of the first crank arm 2, and the first crank arm 2 and the second crank arm 4 are more stable when swinging. Specifically, two third ear plates 211 are fixed to the free end of the upper crank arm rod 21, and the two third ear plates 211 are arranged opposite to each other in an upper and lower manner, and a vertically arranged rotating shaft 102 is arranged between the two third ear plates 211, and the upper end of the rotating shaft 102 is rotatably connected to the third ear plate 211 located above, and the lower end of the rotating shaft 102 is rotatably connected to the third ear plate 211 located below. One end of the steel wire rope 101 is connected to the rotating shaft 102, and the other end is connected to the upper part of the free end of the second crank arm 4.

[0033] Please refer to Figure 1-Figure 3 As shown, in this embodiment, it is also necessary to explain that when in use, when the welding operator adjusts the position of the welding carriage 8, the welding position can be easily changed by rotating the first crank arm 2 and the second crank arm 4, that is, moving to the position of another welding position. In order to prevent the first crank arm 2 and the second crank arm 4 from rotating due to the welding operator pulling the sub-wire 7 when the first crank arm 2 and the second crank arm 4 are rotated to the welding position, an angle positioning adjustment device 9 is respectively provided at the connection position of the first crank arm 2 and the column 1 and at the connection position of the second crank arm 4 and the first crank arm 2. The angle positioning adjustment device 9 is used to position after the first crank arm 2 or the second crank arm 4 adjusts the angle, so as to further realize the positioning of the welding carriage 8.

[0034] Please refer to Figure 2-Figure 5 As shown, in an achievable manner, the angle positioning adjustment device 9 includes a positioning plate 91, a positioning pin 92 and a connecting block 93, and the positioning plate 91 is respectively fixed on the outer side surface of the first ear plate 11 or the second ear plate 221. It can be understood that the outer side surface of the first ear plate 11 is the side away from the first vertical twisted shaft 3, and the outer side surface of the second ear plate 221 is the side away from the second vertical twisted shaft 5, and in this embodiment, it is preferred to set the positioning plate 91 on the first ear plate 11 located below or the second ear plate 221 located below.

[0035] The positioning disk 91 and the first vertical winding shaft 3 or the second vertical winding shaft 5 are coaxially arranged, and a circle of external positioning holes 911 are circumferentially distributed around the center of the positioning disk 91, and the external positioning holes 911 are distributed in a circular array; the connecting block 93 is arranged in a long strip shape, one end of the connecting block 93 is fixed to one side of the first vertical winding shaft 3 or the second vertical winding shaft 5, and the other end of the connecting block 93 is extended toward the edge direction of the positioning disk 91, and the positioning pin 92 is vertically arranged and passes through the connecting block 93. In other words, the positioning pin 92 is installed on the first vertical winding shaft 3 or the second vertical winding shaft 5 through the connecting block 93, and the lower end of the positioning pin 92 can be inserted into the external positioning hole 911. Therefore, when the angle needs to be adjusted, the positioning pin 92 is pulled out, so that the angle of the first curved arm 2 or the second curved arm 4 can be swung. After adjusting to the appropriate position, the positioning pin 92 is inserted into the corresponding external positioning hole 911 again for positioning, thereby limiting the rotation of the first vertical twisted shaft 3 or the second vertical twisted shaft 5, and then limiting the rotation of the first curved arm 2 or the second curved arm 4, thereby avoiding the first curved arm 2 or the second curved arm 4 from swinging after the angle is adjusted.

[0036] It should also be noted that a circle of inner positioning holes 912 are circumferentially distributed around the center of the positioning disk 91, and the inner positioning holes 912 are also distributed in a circular array, and each inner positioning hole 912 is located at the middle position of two adjacent outer positioning holes 911. It can be understood that the distance from the center of the inner positioning hole 912 to the center of the positioning disk 91 is smaller than the distance from the center of the outer positioning hole 911 to the center of the positioning disk 91, that is, the position of the inner positioning hole 912 is closer to the center of the positioning disk 91. The connection block 93 is provided with an adjustment long hole 931, which is extended along the length direction of the connection block 93. The positioning pin 92 is movably arranged in the adjustment long hole 931, and the position of the positioning pin 92 can be inserted into the inner positioning hole 912 or the outer positioning hole 911 by moving the position of the positioning pin 92. When the welding operator needs to adjust the welding position, he removes the positioning pins 92 on the first curved arm 2 and the second curved arm 4, and rotates the first curved arm 2 and the second curved arm 4 to adjust the welding trolley 8 to a suitable position. Since there are enough inner positioning holes 912 and outer positioning holes 911 on the positioning plate 91, and the inner positioning hole 912 corresponds to the middle position of the outer positioning hole 911, the first curved arm 2 and the second curved arm 4 have an inner positioning hole 912 or an outer positioning hole 911 at a position where the circumferential rotation angle is very small, and the adjustment long hole 931 of the connecting block 93 coincides with the positioning pin 92. That is, the positioning pin 92 can be inserted into the inner positioning hole 912 or the outer positioning hole 911. Even if the welding trolley 8 moves a very small displacement, the first curved arm 2 and the second curved arm 4 can be accurately positioned. The positioning pin 92 is inserted to locate the position of the welding trolley 8.

[0037] Please refer to Figure 1 , Figure 2As shown, in this embodiment, it should be noted that the suspension member 6 is configured as a suspension hook, and the welding handle wire 7 of the two-protection welding machine passes through the suspension hooks of the first crank arm 2 and the second crank arm 4. The suspension hook does not limit the movement of the welding handle wire 7, and the welding handle wire 7 is suspended on the first crank arm 2 and the second crank arm 4 through the suspension hook, so it is not affected by the rotation of the first crank arm 2 and the second crank arm 4, and at the same time, it can prevent the welding handle wire 7 from being randomly entangled, so that the working site can be clean and safe, and is particularly suitable for occasions with multiple welding carriages 8 at the same time.

[0038] The implementation principle of this embodiment is as follows: when in use, the protective gas bottle is placed under the column 1 of the workshop, the welding gun line 7 is passed through the hanging piece 6 and hung on the first curved arm 2 and the second curved arm 4, and connected to the welding trolley 8 installed on the free end of the second curved arm 4. When the welding operator needs to adjust the welding position, the positioning pins 92 on the first curved arm 2 and the second curved arm 4 are removed, the first curved arm 2 and the second curved arm 4 are rotated, and the welding trolley 8 is adjusted to a suitable position. After that, the positioning pins 92 are used again to lock the position of the first curved arm 2 and the second curved arm 4, thereby positioning the welding trolley 8. In this way, the welding operator can easily adjust the welding trolley 8 to the upper position of the welding position by rotating the first curved arm 2 and the second curved arm 4, and the welding trolley 8 can quickly move to the upper position of another welding position when changing the position. This device has a simple structure, is convenient for industrialized production in factories, is simple and convenient to operate, has high work efficiency, and is low in cost.

[0039] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
