Description

Technical Field

[0001] This application relates to the field of galvanized welded pipe processing technology, specifically a multi-angle positioning welding device for galvanized welded pipes. Background Technology

[0002] Galvanized welded pipe is a corrosion-resistant pipe material made by galvanizing the surface of ordinary steel pipes. It is divided into two categories: hot-dip galvanizing and cold-dip galvanizing, and is mainly used in building plumbing, gas transmission, and power cable trays. Hot-dip galvanizing uses molten zinc to form an alloy coating with the steel pipe substrate, resulting in a uniform coating and strong adhesion, and is widely used for low-pressure fluid transportation. During the processing, galvanized welded pipes can be assembled using a flash butt welding machine.

[0003] The principle of flash butt welding of reinforcing bars is to use a welding machine to bring the two ends of the reinforcing bars into contact, pass a high current with a low voltage, and heat the reinforcing bars to a certain temperature to soften them. Then, axial pressure is applied for forging to form a welded joint. Existing flash butt welding machines only clamp the welding end of the galvanized welded pipe, which makes it easy for the galvanized welded pipe to be welded crookedly, reducing the welding accuracy.

[0004] Therefore, there is an urgent need for a multi-angle positioning welding device for galvanized welded pipes to solve the problem of easy skewing during welding of galvanized welded pipes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a multi-angle positioning welding device for galvanized welded pipes, which has the advantage of improving the welding accuracy of galvanized welded pipes and solves the problem of easy skewing during welding of galvanized welded pipes.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-angle positioning welding device for galvanized welded pipes, comprising a flash butt welding machine, a support arm and a clamp body, wherein the support arm and the clamp body are disposed on the top of the flash butt welding machine, positioning mechanisms are disposed on both sides of the flash butt welding machine, and an adjustment mechanism is disposed on the top of the flash butt welding machine;

[0007] The positioning mechanism includes a support plate, a support base, a support rod, a fixing plate, a hydraulic cylinder, a connecting rod, and a clamping plate. The support plate is welded to both sides of the flash butt welding machine. The support base is slidably connected to the top of the support plate. The two ends of the support rod are fixedly connected to the outer side of the support base and the inner side of the fixing plate by bolts. The hydraulic cylinder is installed on the outer side of the fixing plate. One end of the connecting rod is fixedly connected to the output end of the hydraulic cylinder. The clamping plate is welded to the other end of the connecting rod.

[0008] When the two sets of clamps move inward, the clamps can clamp the galvanized welded pipe. The clamp body and the clamps at the bottom of the support arm hold the top of the galvanized welded pipe, so that the galvanized welded pipe can be clamped at multiple angles, making it less likely to be skewed during welding and improving the welding accuracy of the galvanized welded pipe.

[0009] Preferably, a guide rod is welded to the inner side of the support base, and a guide sleeve is slidably connected to the other end of the guide rod. The guide sleeve is fixedly connected to the outside of the flash butt welding machine by bolts.

[0010] Preferably, the inner side of the support base has a semi-circular groove.

[0011] Preferably, the clip is a plate with an arc-shaped structure.

[0012] Preferably, the adjustment mechanism includes an electric cylinder, a second connecting rod, a connecting arm, and a second support rod. The electric cylinder is installed on one side of the flash butt welding machine. One end of the second connecting rod is fixedly connected to the output end of the electric cylinder, and the other end of the second connecting rod is fixedly connected to one side of the support arm by bolts. The two ends of the connecting arm are respectively welded to the front of the support arm and one side of the clamp body. The second support rod is welded to the second connecting rod and the inner side of the clamp body.

[0013] Preferably, one end of the second support rod is fixedly connected to the inner side of the support base, and the outer surface of the second support rod is slidably connected to the inner side of the flash butt welding machine.

[0014] Preferably, guide rods are slidably connected to both sides of the support arm, and the two ends of the guide rods are welded to the inside of the flash butt welding machine.

[0015] In summary, this application includes at least one of the following beneficial effects:

[0016] 1. This multi-angle positioning welding device for galvanized welded pipe allows the galvanized welded pipe to be clamped when it is placed in the slots at the top of the clamp body and support base. By adjusting the position of the clamping plates, the two sets of clamping plates can clamp the galvanized welded pipe when they move inward. The clamping parts at the bottom of the clamp body and support arm hold the top of the galvanized welded pipe, allowing the galvanized welded pipe to be clamped at multiple angles. This prevents the galvanized welded pipe from tilting during welding and improves the welding accuracy of the galvanized welded pipe.

[0017] 2. The multi-angle positioning welding device for galvanized welded pipe allows the galvanized welded pipe to be easily moved by adjusting the position of the support arm, which in turn moves the galvanized welded pipe through the clamp body and support base. This makes the welding of the galvanized welded pipe more precise. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-4 A multi-angle positioning welding device for galvanized welded pipe includes a flash butt welding machine 1, a support arm 2, and a clamp body 3. The support arm 2 and the clamp body 3 are located on the top of the flash butt welding machine 1. The support arm 2 clamps the two ends of the galvanized welded pipe through the clamp at the bottom and the clamp body 3, so that the two ends of the galvanized welded pipe can be welded together. Positioning mechanisms are provided on both sides of the flash butt welding machine 1, and an adjustment mechanism is provided on the top of the flash butt welding machine 1.

[0025] Specifically, the positioning mechanism includes a support plate 111, a support base 112, a support rod 113, a fixing plate 114, a hydraulic cylinder 115, a connecting rod 116, and a clamping plate 117. The support plate 111 is welded to both sides of the flash butt welding machine 1. The support base 112 is slidably connected to the top of the support plate 111. The two ends of the support rod 113 are fixedly connected to the outer side of the support base 112 and the inner side of the fixing plate 114 by bolts. A semi-circular slot is opened on the inner side of the support base 112. The hydraulic cylinder 115 is installed on the outer side of the fixing plate 114. One end of the connecting rod 116 is fixedly connected to the output end of the hydraulic cylinder 115. The clamping plate 117 is welded to the other end of the connecting rod 116. The clamping plate 117 is an arc-shaped plate. A guide rod 118 is welded to the inner side of the support base 112. The other end of the guide rod 118 is slidably connected to a guide sleeve 119. The guide sleeve 119 is fixedly connected to the outer side of the flash butt welding machine 1 by bolts.

[0026] With the above technical solution, when the galvanized welded pipe is placed in the slot at the top of the clamp body 3 and the support base 112, the hydraulic cylinder 115 is activated. The hydraulic cylinder 115 drives the clamping plate 117 to move through the connecting rod 116, thereby adjusting the position of the clamping plate 117. When the two sets of clamping plates 117 move inward, the clamping plate 117 can clamp the galvanized welded pipe. The clamping parts at the bottom of the clamp body 3 and the support arm 2 clamp the top of the galvanized welded pipe, so that the galvanized welded pipe can be clamped at multiple angles, making it less likely for the galvanized welded pipe to be skewed during welding and improving the welding accuracy of the galvanized welded pipe. The support base 112 and the support rod 113 support the top structure.

[0027] Specifically, the adjustment mechanism includes an electric cylinder 211, a connecting rod 212, a connecting arm 213, and a support rod 214. The electric cylinder 211 is installed on one side of the flash butt welding machine 1. One end of the connecting rod 212 is fixedly connected to the output end of the electric cylinder 211, and the other end of the connecting rod 212 is fixedly connected to one side of the support arm 2 by bolts. The two ends of the connecting arm 213 are respectively welded to the front of the support arm 2 and one side of the clamp body 3. The support rod 214 is welded to the inner side of the connecting rod 212 and the clamp body 3. One end of the support rod 214 is fixedly connected to the inner side of the support base 112, and the outer surface of the support rod 214 is slidably connected to the inner side of the flash butt welding machine 1.

[0028] With the above technical solution, after the galvanized welded pipe is clamped by the clamping plate 117, the clamp at the bottom of the support arm 2 and the clamp body 3, the electric cylinder 211 is activated. The electric cylinder 211 drives the support arm 2 to slide on the outer surface of the guide rod 215 through the connecting rod 212. By adjusting the position of the support arm 2, the support arm 2 drives the galvanized welded pipe to move through the clamp body 3 and the support seat 112, so that the galvanized welded pipe can be moved easily as a whole, and the welding of the galvanized welded pipe can be more precise; the support arm 2 slides on the outer surface of the guide rod 215 when it moves.

[0029] The clamp body 3 and the connecting arm 213 drive the support base 112 to slide on the top of the support plate 111 via the support rod 214, thereby driving the galvanized welded pipe to move as a whole.

[0030] When in use, when the two sets of clamping plates 117 move inward, the clamping plates 117 can clamp the galvanized welded pipe. The clamping parts at the bottom of the clamp body 3 and the support arm 2 clamp the top of the galvanized welded pipe, so that the galvanized welded pipe can be clamped at multiple angles, making it less likely for the galvanized welded pipe to tilt during welding and improving the welding accuracy of the galvanized welded pipe.
