DETAILED DESCRIPTION

[0038] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0039] Example 1

[0040] See also Figure 1-3 The present embodiment provides a welding device suitable for cable tray installation, which includes a base 100, and two frames 110 are symmetrically arranged on the base 100, and a welding area is formed between the two frames 110; the frame 110 has a circular flipping area along the length direction of the base 100, and a bearing platform 120 for placing the bridge is rotatably provided on the inner wall of the flipping area, and a clamping component 210 for limiting the side wall of the bridge in the width direction is provided at the top of the bearing platform 120.

[0041] When the welding device of this embodiment suitable for cable tray installation is actually used, the corresponding ends of the two cable trays to be welded are placed on the supporting platform 120, and the seam alignment operation is performed. Then, the side walls are limited and clamped by the clamping assembly 210. When welding the connection, the cable trays at both ends can be smoothly turned over by rotating the supporting platform 120. Compared with the prior art, the cable tray can be smoothly turned over during the welding process without manual handling, which reduces labor intensity and welding interruptions and rework caused by improper turning over, and avoids the displacement of the welded parts when turning over the two cable trays at the same time, thereby improving the welding effect.

[0042] The clamping assembly 210 disposed on the top of the supporting platform 120 can effectively limit the side wall of the cable bridge in the width direction, thereby ensuring the stability of the bridge during the welding process.

[0043] The precise adjustment capability of the clamping assembly 210 enables cable trays of different sizes and shapes to be reliably clamped, thereby improving the versatility and adaptability of the device.

[0044] In this embodiment, an annular groove 310 for mounting the support platform 120 is formed on the inner wall of the flipping area. The support platform 120 has a connecting portion that cooperates with the flipping area. A rotating ring 320 that rotates with the annular groove 310 is provided at the bottom of the connecting portion.

[0045] The above structure ensures that the supporting platform 120 can rotate smoothly in the turning area.

[0046] In this embodiment, a slide groove 330 cooperating with the clamping assembly 210 is provided at the top of the support platform 120 along the width direction of the bridge frame. The clamping assembly 210 includes two side panels 430 respectively arranged corresponding to the width directions of the bridge frame and a clamping arm 460 symmetrically arranged in the slide groove 330. The clamping arm 460 is arranged in an inverted L shape. The two side panels 430 are both threadedly connected with a screw 440. One end of the screw 440 is rotatably arranged on the side wall of the clamping arm 460, and the other end of the screw 440 is threadedly penetrated through the side panel 430. The screw 440 penetrates the side panel 430 and one end is fixed with a turning handle 450.

[0047] The setting of the slide groove 330 allows the clamping assembly 210 to slide in the width direction of the bridge, so as to limit the cable bridges of different widths. The inverted L-shaped clamping arm 460 can firmly limit the side walls and top of the bridge, thereby improving safety during flipping.

[0048] Through the threaded screw 440, the user can easily rotate the handle 450 to move the screw 440 in the inner thread of the side plate 430, thereby pushing the clamping arm 460 to slide along the slide groove 330 to achieve precise adjustment of the clamping force of the cable tray.

[0049] In this embodiment, a welding arm 150 is provided at the flipping area, and the welding arm 150 is used to weld the connection between the bridge frame placed on the supporting platform 120 .

[0050] Through the above structure, the welding arm 150 can automatically weld the connection of the cable tray placed on the supporting platform 120 without manual operation of a handheld welding gun, which greatly improves the automation level of welding and further improves work efficiency.

[0051] In this embodiment, a connecting frame 140 is fixedly disposed between the two frames 110 , and the connecting frame 140 is used to connect the two frames 110 and keep them parallel.

[0052] The above structure ensures that the two frames 110 are always in a parallel state, so that they have better stability when flipping, and at the same time, the bridge frame at the supporting platform 120 can always be in a relatively horizontal state.

[0053] In this embodiment, a welding interval is formed between adjacent carriers 120 , and the welding arm 150 is located at the welding interval.

[0054] The above structure ensures that the welding arm 150 has enough space to weld the connection between the two bridge frames, while reducing the interference between the two supporting platforms 120 .

[0055] In this embodiment, a rubber pad is provided at the contact point between the clamping arm 460 and the side wall of the bridge.

[0056] Through the above structure, the pressure and friction force of the clamping arm 460 on the side wall of the bridge can be effectively buffered.

[0057] Example 2

[0058] See Figure 3-6 This embodiment also provides a welding device suitable for cable tray installation, which differs from the first embodiment in that: a mounting cavity corresponding to the ring groove 310 is provided at the frame body 110, a gear 420 is rotatably provided in the mounting cavity, an outer tooth portion 410 is provided at the outer wall of the rotating ring 320, and the outer tooth portion 410 is meshed with the gear 420;

[0059] A groove is disposed at the axis of the gear 420 , and a locking assembly 130 is slidably disposed in the groove and the frame 110 . The locking assembly 130 is used to limit the gear 420 .

[0060] Through the above structure, when in use, after the supporting platform 120 is rotated, the gear 420 can be limited by the locking assembly 130, thereby limiting the supporting platform 120, making it convenient for the user to position the supporting platform 120 at different angles to meet welding requirements at different angles.

[0061] In this embodiment, the locking assembly 130 includes a sleeve 610 disposed at the groove and an extension tube 630 disposed at the frame 110. The sleeve 610 and the extension tube 630 are arranged through each other, and a spline groove 620 is formed on the inner wall of the sleeve 610.

[0062] A locking piece 640 is slidably provided in the extension tube 630, and the locking piece 640 has an expansion portion 650, and the expansion portion 650 is located at the end corresponding to the spline groove 620. A spring 680 is provided between the expansion portion 650 and the inner wall of the extension tube 630, and the spring 680 is used to provide an elastic force to maintain tightness in the direction of the spline groove 620. The locking piece 640 passes through one end of the extension tube 630 and is provided with a connecting handle 510. A plug-in end 660 extending into the spline groove 620 is formed on the side corresponding to the expansion portion 650 and the spline groove 620, and a spline 670 matching the spline groove 620 is formed on the outer wall of the plug-in end 660.

[0063] Through the above structure, the user can quickly unlock or lock the gear 420. The operation is simple, fast and stable. The user can easily achieve the locking and unlocking operations by simply pushing and pulling the connecting handle 510.

[0064] Specifically, in a normal state, due to the elastic force of the spring 680, the spline 670 on the plug end 660 will fit tightly in the spline groove 620, thereby preventing the rotation of the gear 420. At this time, the locking assembly 130 is in a locked state;

[0065] When unlocking is required, the user can pull the locking piece 640 outward through the connecting handle 510. As the locking piece 640 moves, the plug-in end 660 gradually withdraws from the spline groove 620, and the fit between the spline 670 and the spline groove 620 is released. At this time, the gear 420 can rotate freely, and the locking assembly 130 is in an unlocked state.

[0066] In this embodiment, two locking components 130 corresponding to the annular groove 310 are disposed on the frame 110 , and the two locking components 130 are symmetrically disposed on the frame 110 along the center of the flipping area.

[0067] Through the above structure, the two symmetrically arranged locking components 130 are used to further limit the position of the support platform 120, thereby improving the stability of the limit.
