Description

Technical Field

[0001] This application relates to the field of steel structure welding technology, and in particular to a welding device for building steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.

[0003] Existing steel structure welding equipment typically involves fixing two sets of steel structural components to be welded onto corresponding clamps. The clamps are then brought closer together to align the two sets of components, followed by welding at the joint. However, due to the irregular shape of the steel structure, the joint cannot always be aligned with the clamps during welding. This leads to discrepancies at the joint, making welding difficult and inconvenient for users. Summary of the Invention

[0004] This application provides a welding device for building steel structures to solve the problem that existing welding devices for building steel structures generally fix two sets of steel structural members to be welded on corresponding clamps, and then bring the two sets of steel structural members together by bringing the clamps closer to each other, and then perform welding operations on the joint points of the two sets of steel structural members. However, in use, due to the irregular shape of the steel structure, the joint point cannot be guaranteed to always be on the straight line of the two sets of clamps during the welding process. Therefore, differences in the joint point are prone to occur during the jointing process, which makes it inconvenient to perform welding operations on the joint points.

[0005] This application provides a welding device for building steel structures, including an installation beam. An installation box is fixed to the bottom end of the installation beam. A hydraulic rod is installed inside the installation beam. One end of the hydraulic rod is connected to a connecting block. An adjustment box is fixed to the bottom end of the connecting block. An adjustment motor is installed on one side of the adjustment box. A left-right rotating screw is installed at one end of the adjustment motor. Moving nuts are sleeved on the outer walls of both ends of the left-right rotating screw. An adjustment slider is installed on the outer wall of the moving nut. A telescopic rod is installed inside the adjustment slider. An adjustment clamp is connected to the bottom end of the telescopic rod.

[0006] Preferably, a positioning bracket is installed on the top of the mounting box.

[0007] Preferably, a drive motor is installed at one end of the mounting box, and a bidirectional lead screw is installed at one end of the drive motor.

[0008] Preferably, the two ends of the bidirectional lead screw are fitted with lead screw nuts, and the outer walls of the lead screw nuts are equipped with movable sliders.

[0009] Preferably, a limiting plate is installed at the bottom of the movable slider, a clamping plate is connected to the bottom of the limiting plate, and a limiting groove is formed at the bottom of the mounting box.

[0010] Preferably, a limit support frame is installed at the top of the regulating box.

[0011] Preferably, a limiting shaft is installed at the top of the adjusting clamp.

[0012] Beneficial effects:

[0013] Considering that existing steel structure welding equipment typically involves fixing two sets of steel structural components to be welded onto corresponding clamps during welding, and then bringing the clamps closer together to align the two sets of steel structural components, followed by welding at the joint point, the problem arises during use. Due to the irregular shape of the steel structure, the joint point cannot always be guaranteed to be on a straight line between the two clamps during welding. Therefore, differences in the joint point are prone to occur during the welding process, making it difficult to perform welding operations at the joint point.

[0014] By placing the steel structure to be welded between two sets of clamping plates, and then turning on the drive motor to rotate the bidirectional lead screw, the rotation of the lead screw nuts at both ends will cause them to move closer together along the outer wall of the bidirectional lead screw. This will cause the limiting plate and the clamping plate to move closer together, thus clamping and fixing the steel structure to be welded through the two sets of clamping plates. Then, by placing the second set of steel structure between two sets of adjusting clamping plates, and turning on the adjusting motor to rotate the left and right lead screw, the two sets of adjusting clamping plates will move closer together, fixing the second set of steel structure. Then, by opening the hydraulic rod inside the mounting beam, the hydraulic rod will drive the connecting block and the adjusting box to move, causing the adjusting box to move towards the mounting box, so that the two sets of steel structure are connected. During the connection process, if the height of the connection point is different, the telescopic rod inside the adjusting slider can be opened, causing the telescopic rod to move the two sets of adjusting clamping plates up and down for adjustment. This makes it easy for the user to adjust the connection point of the two sets of steel structure, increasing the adjustability of the device.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figure 1-6 The illustrated steel structure welding device includes an installation beam 1, an installation box 2 fixed to the bottom end of the installation beam 1, a hydraulic rod 11 installed inside the installation beam 1, a connecting block 12 connected to one end of the hydraulic rod 11, an adjustment box 13 fixed to the bottom end of the connecting block 12, an adjustment motor 15 installed on one side of the adjustment box 13, a left-right rotating screw 16 installed at one end of the adjustment motor 15, movable nuts 17 sleeved on the outer walls of both ends of the left-right rotating screw 16, an adjustment slider 18 installed on the outer wall of the movable nut 17, a telescopic rod 19 installed inside the adjustment slider 18, and an adjustment clamp 21 connected to the bottom end of the telescopic rod 19.

[0032] In this process, the steel structure to be welded is placed between two sets of clamping plates 9. Then, by turning on the drive motor 4, the bidirectional lead screw 5 rotates. The rotation of the bidirectional lead screw 5 causes the lead screw nuts 6 at both ends to move closer together along the outer wall of the bidirectional lead screw 5, thereby causing the limiting plate 8 and the clamping plate 9 to move closer together. The two sets of clamping plates 9 clamp and fix the steel structure to be welded. Then, by placing the second set of steel structure components between two sets of adjusting clamping plates 21, and by turning on the adjusting motor 15, the left and right rotating lead screw 16 rotates, thereby causing the two… The adjusting clamps 21 are brought closer together to fix the second set of steel structural components. Then, by opening the hydraulic rod 11 inside the mounting beam 1, the connecting block 12 and the adjusting box 13 are moved, causing the adjusting box 13 to move towards the mounting box 2, so that the two sets of steel structural components are connected. During the connection process, if the height of the connection point is different, the telescopic rod 19 inside the adjusting slider 18 can be opened, so that the telescopic rod 19 drives the two sets of adjusting clamps 21 to move up and down for adjustment. This makes it easier for the user to adjust the connection point of the two sets of steel structural components, increasing the adjustability of the device.

[0033] The top of the mounting box 2 is equipped with a positioning bracket 3.

[0034] The installation stability of the mounting box 2 is increased by installing two sets of positioning brackets 3 at the top of the mounting box 2 and fixing the mounting box 2 to the bottom of the mounting beam 1 through the two sets of positioning brackets 3.

[0035] One end of the mounting box 2 is equipped with a drive motor 4, and the other end of the drive motor 4 is equipped with a bidirectional lead screw 5.

[0036] The steel structure to be welded is placed between two sets of clamping plates 9, and then the drive motor 4 is turned on to make the bidirectional lead screw 5 rotate.

[0037] The two ends of the double-acting lead screw 5 are fitted with lead screw nuts 6, and the outer walls of the lead screw nuts 6 are fitted with movable sliders 7.

[0038] When the bidirectional lead screw 5 drives the lead screw nut 6 to move, the movable slider 7 fixed on the outer wall of the lead screw nut 6 will also move synchronously.

[0039] A limiting plate 8 is installed at the bottom of the movable slider 7, and a clamping plate 9 is connected to the bottom of the limiting plate 8. A limiting groove 10 is opened at the bottom of the mounting box 2.

[0040] When the movable slider 7 moves, it will move along the inside of the limiting groove 10 at the bottom of the mounting box 2. The limiting groove 10 limits the movement of the movable slider 7, thereby increasing the stability of the movement of the movable slider 7.

[0041] A limit support frame 14 is installed at the top of the regulating box 13.

[0042] Among them, by installing two sets of limiting support frames 14 at the top of the regulating box 13, the two sets of limiting support frames 14 are movably inserted into the interior of the two sets of positioning inclined frames 3, and the movement of the mounting box 2 is supported and limited by the two sets of limiting support frames 14 and the two sets of positioning inclined frames 3, thereby increasing the movement stability of the mounting box 2.

[0043] A limit shaft 20 is installed at the top of the adjusting clamp 21.

[0044] The movement stability of the adjusting clamp 21 is increased by installing four sets of limiting shafts 20 at the top of the adjusting clamp 21 and limiting the movement of the adjusting clamp 21 by the four sets of limiting shafts 20.

[0045] Working principle: When using this steel structure welding device, the steel structure to be welded is placed between two sets of clamping plates 9. Then, by turning on the drive motor 4, the bidirectional lead screw 5 rotates. Under the rotation of the bidirectional lead screw 5, the lead screw nuts 6 at both ends move closer to each other along the outer wall of the bidirectional lead screw 5, thereby causing the limiting plate 8 and the clamping plate 9 to move closer to each other. The steel structure to be welded is clamped and fixed by the two sets of clamping plates 9. Then, by placing the second set of steel structure components between two sets of adjusting clamping plates 21, the adjusting motor 15 is turned on, causing the left and right rotating lead screw 16 to rotate, thereby causing the two sets of adjusting clamping plates 21 to move closer to each other and fix the second set of steel structure components.

[0046] Subsequently, by opening the hydraulic rod 11 inside the mounting beam 1, the hydraulic rod 11 drives the connecting block 12 and the adjusting box 13 to move, causing the adjusting box 13 to move towards the mounting box 2, so that the two sets of steel structural components can be connected. During the connection process, when the height of the connection point is different, the telescopic rod 19 inside the adjusting slider 18 can be opened, so that the telescopic rod 19 drives the two sets of adjusting clamps 21 to move up and down for adjustment, thereby making it convenient for the user to adjust the connection point of the two sets of steel structural components and increasing the adjustability of the device.

[0047] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
