DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The guardrail welding auxiliary device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 5 As shown, the guardrail welding auxiliary device of the embodiment of the present invention may include: a limiter 1 and a plurality of guardrail upright pole fixing devices 2, wherein the plurality of guardrail upright pole fixing devices 2 are slidably arranged on the limiter 1. The guardrail upright pole fixing device 2 may include: a hollow block 21, a first electromagnet 22, an electric telescopic rod 23, a weighing device 24, a rotating device 25, and a clamping and fixing device 26, wherein the hollow block 21 is slidably connected to the limiter 1, and the hollow block 21 is magnetically connected to the limiter 1 through the first electromagnet 22, the electric telescopic rod 23 is arranged on the hollow block 21, the weighing device 24 is arranged on the telescopic end of the electric telescopic rod 23, the rotating device 25 is arranged on the weighing device 24, and the clamping and fixing device 26 is arranged on the rotating device 25. It should be noted that the hollow block 21 may be made of iron material.

[0036] It can be understood that the hollow block 21 described in this embodiment can slide on the limit member 1 to facilitate moving the guardrail upright to a suitable welding position, and after reaching the welding position of the guardrail upright, the first electromagnet 22 generates a magnetic force, and the first electromagnet 22 is magnetically attracted to the limit member 1 to fix the hollow block 21, so that the guardrail upright is stably fixed in the welding position.

[0037] The clamping and fixing device 26 is used to obtain the weight information of the guardrail upright pole according to the weighing device 24 and clamp and fix the guardrail upright pole.

[0038] It should be noted that the weighing device 24 described in this embodiment can weigh the guardrail pole placed on the clamping and fixing device 26 to obtain the weight information of the guardrail pole. If the weight information of the guardrail pole meets the preset weight, the clamping and fixing device 26 can clamp and fix the guardrail pole. If the weight information of the guardrail pole does not meet the preset weight, the clamping and fixing device 26 will not clamp and fix the guardrail pole.

[0039] The rotating device 25 is used to drive the clamping and fixing device 26 to rotate according to the clamping condition of the clamping and fixing device 26.

[0040] It should be noted that the clamping and fixing device 26 described in this embodiment has different clamping conditions for guardrail uprights in different placement forms (different clamping conditions where the length dimension of the lower surface of the guardrail upright is smaller than the height dimension of the side surface of the guardrail upright or the length dimension of the lower surface of the guardrail upright is larger than the height dimension of the side surface of the guardrail upright). The placement form of the guardrail upright in the clamping and fixing device 26 is adjusted by rotating the clamping and fixing device 26.

[0041] In order to clearly explain the above embodiment, in one embodiment of the present invention, as Figure 2-Figure 5 As shown, the rotating device 25 may include: a load-bearing platform 251, a first motor 252 and a driving wheel 253, wherein the load-bearing platform 251 is arranged on the weighing device 24, a plurality of limit grooves 254 are opened on the inner wall of the load-bearing platform 251, an installation groove 255 is opened on the inner wall of the load-bearing platform 251, the first motor 252 is arranged in the installation groove 255, the driving wheel 253 is arranged on the driving end of the first motor 252, and the clamping and fixing device 26 is connected to the driving wheel 253.

[0042] The clamping and fixing device 26 may include: a placement table 261, a ring gear 262, two electric push rods 263 and two clamping plates 264, the two electric push rods 263 correspond to the two clamping plates 264 one by one, wherein the placement table 261 is a cylinder with a groove, the ring gear 262 is fixedly arranged on the outer wall of the placement table 261, the ring gear 262 is meshed with the driving wheel 253, the two electric push rods 263 are symmetrically arranged on the inner wall of the placement table 261, the clamping plates 264 are fixedly arranged on the telescopic ends of the electric push rods 263, and the clamping plates 264 are provided with pressure sensors 265, wherein a plurality of limiting slides 266 are respectively arranged on the outer walls of the placement table 261, the limiting slides 266 are slidably connected to the limiting grooves 254, and the rotating device 25 is used to drive the clamping and fixing device 26 to rotate according to the telescopic length of the telescopic ends of the electric push rods 263.

[0043] As a possible situation, the limiting slide plate 266 may be a steel plate, and the limiting groove 254 supports the placement table 261 by limiting the limiting slide plate 266 .

[0044] As another possible situation, the limiting slide 266 may be an electromagnet plate, and the limiting groove 254 supports the placement table 261 by limiting the limiting slide 266, and fixes the placement table 261 through the magnetic connection between the limiting slide 266 and the load-bearing platform 251.

[0045] like Fig. 9 As shown, specifically, when performing the guardrail welding process, relevant personnel take a plurality of required guardrail uprights from the upright rack, and place the guardrail uprights into the corresponding guardrail upright fixing devices 2 in sequence according to their lengths. After the guardrail uprights are placed on the placement table 261, the weight information detected by the weighing device 24 changes. If the value of the weight information change meets the preset value, the electric push rod 263 controls the splint 264 to clamp the guardrail uprights. The pressure sensor 265 on the splint 264 can ensure the clamping accuracy of the splint 264 on the guardrail uprights.

[0046] When the length and width of the cross-section of the guardrail pole are similar, it is easy for relevant personnel to make mistakes when placing the guardrail pole on the placement platform 261. When the placement of the guardrail pole is wrong, the clamping and fixing device 26 will still clamp the guardrail pole, and the relevant personnel can continue to place other guardrail poles. The rotating device 25 can judge the placement of the guardrail pole by the extended length of the telescopic end of the electric push rod 263. When the placement is wrong, the first motor 252 is started, and the first motor 252 controls the driving wheel 253 to rotate. The driving wheel 253 drives the placement platform 261 to rotate by meshing with the ring gear 262, so as to automatically adjust the placement of the guardrail pole and fine-tune the vertical position of the guardrail pole through the electric telescopic rod 23.

[0047] After all the guardrail uprights are placed, relevant personnel can control the guardrail upright fixing device 2 to slide to a suitable working position on the limit piece 1. It should be noted that the guardrail upright fixing device 2 adjusted by the rotating device 25 must be adjusted accordingly at the working position of the limit piece 1 to ensure that the position of the guardrail upright after placement meets the preset position.

[0048] This method reduces the need for rework after errors in the placement and specifications of the guardrail uprights after clamping and fixing, thereby improving work efficiency and reducing the scrap rate of the finished guardrail product by testing the specifications of the guardrail uprights and adjusting the placement.

[0049] In one embodiment of the present invention, Figure 8 and Fig. 9 As shown, it may also include: a driving component 4, which is used to drive the guardrail upright fixing device 2 to move on the limit member 1.

[0051] Specifically, the second motor 42 can drive the first ball screw 43 to rotate, the first ball slider 44 can rotate on the rotating first ball screw 43, the moving first ball slider 44 can drive the third electromagnet 46 to move through the mounting plate 45, and the third electromagnet 46 can control the movement of the hollow block 21 on the limit member 1 through a magnetic connection with the hollow block 21.

[0052] Furthermore, a second electromagnet 3 is provided at the end of the hollow block 21, and two adjacent hollow blocks 21 can be detachably connected through the second electromagnet 3.

[0053] It can be understood that the second electromagnet 3 described in this embodiment can identify the positioning point on the hollow block 21 through a positioner, so as to achieve accurate magnetic attraction of the second electromagnet 3 to the hollow block 21 .

[0054] It should be noted that the two adjacent hollow blocks 21 described in this embodiment are detachably connected by the second electromagnet 3. When the moving third electromagnet 46 moves a hollow block 21, it can push the hollow blocks 21 to the target working position at the same time. There is no need for the drive component 4 to control the third electromagnet 46 to retract after positioning one hollow block 21 to move the next hollow block 21, thereby improving work efficiency.
