Spot welding positioning of the connecting plates in the electrical hanger supports is one of the more common constructions in the nuclear power installation industry.

[0003] In the past, for the spot welding positioning of electrical hanger supports, after the base plate and square steel were welded, construction workers still had to manually mark lines on the base plate for positioning, and weld the two connecting plates to the marked positions on the base plate. When spot welding the electrical hanger supports, the connecting plates in the electrical hanger supports were not feasibly positioned, resulting in low work efficiency and a low compliance rate for the precision requirements of the spot welded electrical hanger supports.

DETAILED DESCRIPTION

[0031] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 3 As shown, an embodiment of the utility model provides a spot welding positioning device for an electrical hanger support, comprising: a support, two second limiting members 06 and two first limiting members 04;

[0033] The two second limiting members 06 and the two first limiting members 04 are arranged on the same side of the support, and the two first limiting members 04 are both located above the two second limiting members 06;

[0034] The first limiting member 04 is used to limit the connection plate;

[0035] The upper surfaces of the two second position-limiting members 06 are located on the same horizontal plane, and the distance between the projections of the two first position-limiting members 04 on the plane where the upper surfaces of the second position-limiting members 06 are located is smaller than the distance between the two second position-limiting members 06;

[0036] A limiting area is formed between the two second limiting members 06, and the limiting area is used to limit the square steel and / or the limiting area is used to limit the bottom plate.

[0037] The welded base plate 500 and square steel 400 are placed between the two second limiting members 06 to limit the base plate 500 and / or the square steel 400, and the two connecting plates 300 are placed on the base plate 500. The connecting plates 300 are limited by the two first limiting members 04, so that the two connecting plates 300 and the base plate 500 can be positioned, replacing the manual positioning method of marking on the base plate 500, thereby improving work efficiency. In addition, since the connecting plates 300 are feasibly limited, the labor intensity of the workers is reduced, and the electric welded electrical hanger support has a high accuracy compliance rate and meets the accuracy requirements.

[0038] Preferably, the two second limiting members 06 are used to limit the other steel, and the upper surfaces of the two second limiting members 06 are in contact with the lower surface of the bottom plate.

[0039] Preferably, the limiting area formed between the two second limiting members 06 is used to limit the other steel 400. At this time, the lower surface of the bottom plate 500 contacts the upper surfaces of the two second limiting members 06, so that the two second limiting members 06 support the bottom plate 500.

[0040] Optionally, two second limiting members 06 are used to limit the bottom plate.

[0041] Optionally, the limiting area formed between the two second limiting members 06 is used to limit the bottom plate 500. At this time, the two second limiting members 06 both include a first strip block and a second strip block. The two first strip blocks are fixedly connected to the second strip block on one side close to each other. The upper surfaces of the second strip blocks are parallel to each other. Once the two ends of the bottom plate 500 are on the second strip blocks, the distance between the two first strip blocks can just accommodate the bottom plate 500, thereby playing a role in limiting the bottom plate 500.

[0042] Furthermore, the distance between the upper surface of the two first strip blocks and the upper surface of the second strip block is less than the thickness of the base plate 500, thereby preventing the first strip blocks from protruding from the upper surface of the base plate 500, causing inconvenience to workers when welding the two connecting plates 300 to the base plate 500.

[0043] Furthermore, the support also includes a limit block 09, which is arranged between the two second limit members 06, and the limit block 09 cooperates with the two second limit members 06 to limit the other steel.

[0044] Specifically, one side of the limit block 09 is connected to the lower vertical plate 03, and the other side opposite to the limit block 09 is connected to the square steel 400 when the electrical hanger support is welded. The square steel 400 is placed in the limit area, and the first side of the square steel 400 is in contact with the first side (the square steel 400 has four sides, which are respectively recorded as the first side, the second side, the third side and the fourth side, wherein the first side and the fourth side are parallel to each other, and the second side and the third side are parallel to each other), and the square steel 400 is pressed against the second side and the third side of the square steel 400 are in contact with the two second limit members respectively, so that the two second limit members 06 and the limit block jointly limit the square steel 400.

[0045] In this embodiment, a limiting groove 05 for limiting the connection plate is formed on the first limiting member 04 .

[0046] Specifically, the width of the limiting groove 05 is adapted to the plate thickness of the connecting plate 300 , so that when the connecting plate 300 is placed upright in the limiting groove 05 , the connecting plate 300 and the bottom plate 500 are perpendicular to each other.

[0047] Preferably, the first limiting member 04 is a third strip block, and a limiting groove 05 is provided at one end of the third strip block away from the upper vertical plate, and the limiting groove 05 is in the shape of a rectangular groove.

[0048] Optionally, the first limiting member 04 includes a concave plate, the spacing between the two inner walls of the concave plate is greater than the thickness of the connecting plate 300, a threaded hole is opened on one side of the concave plate, a screw is threaded inside the threaded hole, and the connecting plate 300 is pressed against the connecting plate 300 by the Ningdong screw to limit the connecting plate 300.

[0049] Specifically, the support includes a lower vertical plate 02 and an upper vertical plate 03;

[0050] The upper vertical plate 03 is connected above the lower vertical plate 02, and the two first position-limiting members 04 are both connected to the upper vertical plate 03;

[0051] The two second stoppers 06 are both connected to the lower vertical plate 02;

[0052] The support also includes a horizontal plate 01 , and a lower vertical plate 02 is installed above the horizontal plate 01 .

[0053] Furthermore, a groove is formed on the lower vertical plate 02, and a protrusion matched with the groove is formed on the upper vertical plate 03. This structure enables the upper vertical plate 03 and the lower vertical plate 02 to be offset left and right when the lower vertical plate 02 and the upper vertical plate 03 are welded.

[0054] Optionally, the support also includes a mounting plate, and a plurality of first screw holes are provided on the upper vertical plate 03, the lower vertical plate 02 and the mounting plate, and the mounting plate is arranged between the lower vertical plate 02 and the upper vertical plate 03. The mounting plate and the upper vertical plate 03 as well as the mounting plate and the lower vertical plate 02 are fixed in place by screwing bolts into corresponding first screw holes, thereby completing the installation of the upper vertical plate 03 and the lower vertical plate 02.

[0055] Preferably, the sum of the weight of the electrical hanger support, the upper vertical plate 03 and the lower vertical plate 02 is less than the weight of the horizontal plate 01, so that the support is not easy to tip over.

[0056] Furthermore, the support also includes an anti-dumping fixing member 08 and two supporting members 07;

[0057] The anti-dumping fixing member 08 is fixedly connected to the transverse plate 01 , and the two supporting members 07 are fixedly connected to the anti-dumping fixing member 08 . The upper surfaces of the two supporting members 07 are in contact with the lower surfaces of the two second limiting members 06 , respectively.

[0058] Furthermore, an anti-dumping fixture 08 is connected next to the support, so that the center of gravity of the entire device is lowered, and the anti-dumping fixture 08 occupies a larger area and can better support the entire device.

[0059] Specifically, the upper surfaces of the two support members 07 are against the lower surfaces of the two second limiting members 06, so that one end of the second limiting member 06 is fixed on the lower vertical plate 02, and the other end is supported on the support member 07, so that the second limiting member 06 has better stability, and the square steel 400 placed in the limiting area can be limited more stably.

[0060] It should be noted that the distance between the two support members 07 is greater than or equal to the distance between the two second limit members 06 so that they will not interfere with the square steel 400.

[0061] Preferably, the anti-dumping fixing member 08 is a concave plate. The shape of the concave plate can not only play a supporting role for the entire device, but also the hollow position of the concave plate can reduce material loss and reduce production costs.

[0062] As a specific embodiment, a clearance area is provided on the second limiting member 06 .

[0063] The second limit member 06 is provided with a clearance area to make room for the welding points at the connection between the bottom plate 500 and the square steel 400, so as to prevent the welding points from having no accommodation area, resulting in the lower surface of the bottom plate 500 not being able to fully contact with the upper surface of the second limit member 06, causing the bottom plate 500 to shake and resulting in inaccurate welding point positions when the bottom plate 500 is welded to the connecting plate 300.

[0064] As a specific embodiment, two first strip grooves are formed on the upper vertical plate 03 , and first clamping grooves are formed at one end of the two first limiting members 04 away from the limiting grooves 05 , and the first clamping grooves are embedded in the first strip grooves.

[0065] The first strip groove and the first card groove are matched with each other, and the first card groove is embedded in the first strip groove, thereby fixing the first limiting member 04 and the upper vertical plate 03 in place, so that when the first limiting member 04 and the upper vertical plate 03 are welded, the first limiting member 04 is not easy to be misplaced, thereby ensuring the accuracy of the welding point, and then ensuring the accuracy of the limiting of the connecting plate 300.

[0066] As a specific embodiment, the lower vertical plate 02 is symmetrically provided with second strip grooves, and the ends of the two second limiting members 06 close to the lower vertical plate 02 are both provided with second card slots, and the second card slots are embedded in the second strip grooves.

[0067] According to calculations, when the electric welding positioning device is not used, it takes an average of 0.2 minutes to spot weld the electrical hanger support. After using the electric welding positioning device, it takes an average of 40 seconds to spot weld the electrical hanger support, which improves work efficiency.

[0068] Compared with the marking welding, the first limiter 04 and the second limiter 06 are used to limit the connection plate 300 and the bottom plate 500, thereby effectively preventing and reducing welding deformation, and reducing the damage to the human body caused by the slip of the weldment when the welder positions the connection plate 300.

[0069] The second strip groove is matched with the second card groove, and the second card groove is embedded in the second strip groove, thereby preliminarily fixing the second limit piece 06 and the lower vertical plate 02, so that when the second limit piece 06 is welded to the lower vertical plate 02, the second limit piece 06 is not easy to be misplaced, thereby ensuring the accuracy of the welding point, and then ensuring the accuracy of the limit to the other steel 400.

[0070] Specifically, the installation process is: first weld the anti-dumping fixing piece 08 and the two supporting pieces 07 together, then weld the upper vertical plate 03 and the two first limiting pieces 04 together, weld the lower vertical plate 02 and the two second limiting pieces 06 together, and finally weld the upper vertical plate 03, the lower vertical plate 02, the anti-dumping fixing piece 08 and the cross plate.

[0071] Working method: workers insert the welded square steel 400 into the two second limit pieces 06. At this time, the bottom plate 500 is placed on the upper surface of the two second limit pieces 06 to support the bottom plate 500. The two connecting plates 300 are respectively placed in the limit grooves 05 opened on the first limit pieces 04. One worker holds the connecting plate 300, and another worker welds the two bottom corners 200 of each connecting plate 300 to the bottom plate 500.
