Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for steel scaffolding treads. Background Technology

[0002] As an important load-bearing component of scaffolding systems in building construction, steel scaffolding planks require welding processes during production to connect steel components, ensuring structural strength and safety.

[0003] Currently, most devices used for welding steel scaffolding treads adopt traditional welding host structures, which still have room for improvement in actual operation and use: the lengths of the grounding cable and welding gun cable that come with the welding device usually need to be adapted to different working scenarios. Existing devices lack dedicated cable storage structures, and when idle, the cables are easily placed randomly and tangled together, forming messy tangles. This not only takes up space and affects the cleanliness of the working environment, but also requires extra time to tidy up before use, reducing work efficiency. Furthermore, the tangling process can easily cause wear and tear on the cable sheath, posing a potential electrical safety hazard. Utility Model Content

[0004] This utility model proposes a scaffolding steel tread welding device to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scaffolding steel tread welding device, comprising a welding host, a handle fixedly connected to the top of the welding host, symmetrically distributed heat sinks fixedly arranged on both side walls of the welding host, a grounding cable and a welding gun cable symmetrically arranged on one side wall of the welding host, the grounding cable and the welding gun cable being electrically connected to the internal circuit of the welding host, a control panel and an adjustment knob embedded in the front of the welding host, the adjustment knob being electrically connected to the control panel, rollers fixedly connected to the four corners of the bottom of the welding host, a pull-out handle that can be extended and retracted in the vertical direction slidably connected to the back of the welding host, and a set of wire harness assemblies fixedly arranged on each of the two outer side walls of the welding host.

[0006] Preferably, each wire harness assembly includes a fixing seat and a connecting seat. The fixing seat and the connecting seat are spaced apart along the height direction of the welding host sidewall and are fixedly connected to the welding host sidewall on one side. A winding rod is fixedly connected to the side of the fixing seat away from the welding host in the horizontal direction. An external thread is provided on the outer peripheral wall of the winding rod. A threaded sleeve is slidably inserted inside the connecting seat along the axis of the winding rod. The internal thread of the threaded sleeve is adapted to the external thread of the winding rod. A clamping block is fixedly connected to the end of the threaded sleeve away from the connecting seat. The threaded sleeve can be screwed in / out along the winding rod, causing the clamping block to move closer / away from the cable wound on the winding rod.

[0007] Preferably, a rubber gasket is fixedly connected to the side of the clamping block near the winding rod, and the size of the rubber gasket is adapted to the end face size of the clamping block near the winding rod.

[0008] Preferably, an auxiliary seat is fixedly connected to the end of the winding rod away from the fixed seat. The cross-section of the auxiliary seat is an isosceles trapezoid, and the maximum outer diameter of the auxiliary seat is greater than the outer diameter of the winding rod, which is used to limit the threaded sleeve.

[0009] Preferably, an operating block is fixedly connected to the end of the threaded sleeve away from the clamping block. Anti-slip protrusions are evenly distributed on the outer peripheral wall of the operating block, and the outer diameter of the operating block is larger than the outer diameter of the threaded sleeve.

[0010] Preferably, on both side walls of the welding host, a set of cleaning components is provided on the outer side of the heat sink. Each set of cleaning components includes two parallel and spaced guide shafts. The axis of the guide shaft is set along the height direction of the heat sink, and both ends of the guide shaft are fixedly connected to the side wall of the welding host. A sliding plate is slidably sleeved on the outer peripheral wall of the two guide shafts. The sliding plate can slide up and down along the axial direction of the guide shaft, and a cleaning brush is fixedly connected to the side of the sliding plate near the heat sink. The bristles of the cleaning brush are in contact with the surface of the heat sink.

[0011] Preferably, a limiting disc is fixedly sleeved at the end of the guide shaft away from the welding host. The outer diameter of the limiting disc is larger than the outer diameter of the guide shaft to prevent the sliding plate from sliding off the guide shaft. A positioning pin is also threaded through the surface of the sliding plate. One end of the positioning pin passes through the sliding plate and abuts against the outer peripheral wall of the guide shaft to lock the position of the sliding plate on the guide shaft.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting cable bundling assemblies on both sides of the welding host, the problem of storing grounding cables and welding gun cables is effectively solved. The winding rod can realize the orderly winding of cables and avoid them from tangling together. The threaded engagement between the threaded sleeve and the winding rod can drive the clamping block to precisely clamp the cable. With the rubber gasket, the cable sheath can be prevented from being crushed by elastic contact, and the friction with the cable can be increased to improve the stability of the fixation. The auxiliary seat can not only limit the threaded sleeve to prevent it from over-rotating and detaching from the winding rod, but also guide the threaded sleeve to accurately engage with the winding rod. The anti-slip protrusions on the outer periphery of the operating block make it easy for the operator to hold and rotate the threaded sleeve without the need for additional tools, which significantly improves the convenience of cable storage and fixation, and ensures the safety and cleanliness of the cable during use.

[0014] In this invention, the ease of cleaning and maintaining the heat sink is greatly improved. The cleaning components set on the outer side of the heat sink on both sides of the welding host restrict the movement trajectory of the sliding plate through the guide shaft, so that the sliding plate can only slide along the height direction of the heat sink. The cleaning brush on the sliding plate can directly sweep the dust and debris on the surface of the heat sink during movement without disassembling the parts. The limiting disc can prevent the sliding plate from sliding off the guide shaft, and the positioning pin can fix the sliding plate in a designated position when cleaning is not required, preventing it from sliding randomly and affecting heat dissipation. This effectively ensures the heat dissipation efficiency of the heat sink, extends the service life of the welding host, and reduces the difficulty of equipment maintenance.

[0019] Example 1, referring to Figures 1-3As shown, this embodiment discloses a scaffolding steel treadle welding device with a welding host 1 as the core load-bearing structure. The welding host 1 adopts a box-type structure design, which integrates the circuit modules, transformers, and protection components required to realize the welding function, providing core power and circuit protection for the operation of the entire device. A handle 5 is fixedly connected to the top center of the welding host 1. The handle 5 is made of high-strength metal material and its shape is adapted to the curvature of the human hand, making it convenient for operators to move and transfer the device. Heat sinks 2 are fixedly installed on both side walls of the welding host 1. The heat sinks 2 are arranged in a sheet-like and spaced manner against the side walls of the welding host 1, which can quickly dissipate the heat generated inside the welding host 1 during operation, preventing internal components from being affected or damaged due to overheating. A grounding cable 3 and a welding torch cable 6 are also symmetrically arranged on one side wall of the welding host 1. One end of the grounding cable 3 and the welding torch cable 6 extend into the welding host 1 and are stably electrically connected to the internal circuit. The other end is used to connect the grounding clamp and the welding torch, respectively, to meet the grounding protection and welding operation requirements during welding operations. The front of the welding host 1 is equipped with a control panel and an adjustment knob, which are electrically connected to the control panel. The control panel features a display screen for showing welding parameters and control buttons for starting, stopping, and switching modes. The adjustment knob allows for the adjustment of key parameters such as current and voltage during the welding process, enabling operators to make precise settings according to the welding requirements of the steel treadle. Rollers 18 are fixedly connected to the four corners of the bottom of the welding host 1. These rollers 18 are omnidirectional wheels with braking functions, allowing the operator to move the device in any direction by pushing it. Once the device is moved to the designated welding position, the braking components on the rollers 18 can be pressed to secure the device and prevent slippage during operation. A retractable handle 6 is slidably connected to the back of the welding host 1. When not in use, the handle 6 can be retracted into a pre-set storage block on the back of the welding host 1 to avoid occupying extra space. When in use, it can be pulled out for the operator to grip and move the device.

[0020] On each of the two outer side walls of the welding host 1, a set of wire harness assemblies 7 are fixedly installed. Each set of wire harness assemblies 7 includes a fixing seat 11 and a connecting seat 16. The fixing seat 11 and the connecting seat 16 are spaced apart along the height direction of the side wall of the welding host 1, and one side of both is fixedly connected to the side wall of the welding host 1 by bolts or welding to ensure structural stability. On the side of the fixing seat 11 away from the welding host 1, a winding rod 12 is fixedly connected horizontally. The outer peripheral wall of the winding rod 12 is provided with external threads. The length of the winding rod 12 is adapted to the winding requirements of the grounding cable 3 or the welding gun cable 6, and idle cables can be wound in an orderly manner on its surface. A threaded sleeve 13 is slidably inserted inside the connecting seat 16 along the axis of the winding rod 12. The internal thread of the threaded sleeve 13 is adapted to the external thread of the winding rod 12. A clamping block 14 is fixedly connected to the end of the threaded sleeve 13 away from the connecting seat 16. The shape of the clamping block 14 can be circular or square, and its end face area is slightly larger than the cross-sectional area of ​​the winding rod 12 so as to better fit the wound cable. A rubber gasket 15 is fixedly connected to the side of the clamping block 14 near the winding rod 12. The rubber gasket 15 is made of elastic rubber and its size is perfectly matched to the end face size of the clamping block 14 near the winding rod 12. When clamping the cable, it can not only prevent the cable sheath from being damaged, but also increase the friction with the cable through its own elasticity, thereby improving the stability of the cable fixation. An auxiliary seat 17 is fixedly connected to the end of the winding rod 12 away from the fixing seat 11. The cross-section of the auxiliary seat 17 is an isosceles trapezoid. The small end of the auxiliary seat 17 is fixedly connected to the end of the winding rod 12 away from the fixing seat 11, and the large end is set in the direction away from the winding rod 12. The maximum outer diameter of the auxiliary seat 17 is larger than the outer diameter of the winding rod 12. This not only limits the screwing distance of the threaded sleeve 13, preventing the threaded sleeve 13 from over-screwing and dislodging from the winding rod 12, but also guides the threaded sleeve 13 when it is screwed into the winding rod 12, ensuring that the threaded sleeve 13 and the winding rod 12 are precisely matched. An operating block is fixedly connected to the end of the threaded sleeve 13 away from the clamping block 14. The operating block has a cylindrical structure and anti-slip protrusions are evenly distributed on its outer peripheral wall. The anti-slip protrusions can be strip-shaped or dot-shaped, which makes it convenient for the operator to directly hold and rotate the operating block without the need for additional tools. At the same time, the outer diameter of the operating block is larger than the outer diameter of the threaded sleeve 13, which can prevent the threaded sleeve 13 from completely sliding into the connecting seat 16, making it convenient for subsequent operation of the threaded sleeve 13.

[0021] On both sides of the welding host 1, on the outer side of the heat sink 2, there is a set of cleaning components. Each set of cleaning components includes two parallel and spaced guide shafts 9. The axis of the guide shafts 9 is set along the height direction of the heat sink 2. Both ends of the guide shafts 9 are fixedly connected to the side wall of the welding host 1 by welding or screwing, ensuring that the guide shafts 9 are stable and maintain a suitable distance from the heat sink 2. A sliding plate 91 is slidably fitted on the outer peripheral wall of the two guide shafts 9. The inner wall of the sliding plate 91 is in close contact with the outer peripheral wall of the guide shaft 9, so that the sliding plate 91 can only slide up and down along the axial direction of the guide shaft 9 and will not deviate. A cleaning brush 92 is fixedly connected to the side of the sliding plate 91 near the heat sink 2. The bristles of the cleaning brush 92 are made of wear-resistant nylon material. The end of the bristles away from the sliding plate 91 is in close contact with the surface of the heat sink 2, which can clean the dust, debris and other impurities attached to the surface of the heat sink 2 when the sliding plate 91 moves. A limiting disc 93 is fixedly fitted at the end of the guide shaft 9 away from the welding host 1. The outer diameter of the limiting disc 93 is larger than the outer diameter of the guide shaft 9, which can limit the sliding stroke of the sliding plate 91 and prevent the sliding plate 91 from sliding off the guide shaft 9 during the sliding process. A positioning pin 10 is also threaded through the surface of the sliding plate 91. One end of the positioning pin 10 passes through the sliding plate 91 and can abut against the outer peripheral wall of the guide shaft 9. When it is not necessary to clean the heat sink 2, tighten the positioning pin 10 to make it abut against the guide shaft 9, so that the sliding plate 91 can be fixed at a designated position (such as the top or bottom) on the guide shaft 9, and prevent the sliding plate 91 from sliding randomly and affecting the heat dissipation effect of the heat sink 2.

[0022] Working principle

[0023] When using the scaffolding steel tread welding device, first move the device according to the needs of the welding work site. Pull out the pull handle 6 on the back of the welding host 1, hold the pull handle 6 and push the device. The device is moved by the roller 18 at the bottom. When the device moves to the target position, step on the brake component on the roller 18 to lock the roller 18 and keep the device in a fixed state. If the grounding cable 3 and the welding gun cable 6 are idle, the grounding cable 3 or the welding gun cable 6 can be wound in an orderly manner on the winding rods 12 on both sides of the welding host 1. After winding, hold the operating block at the end of the threaded sleeve 13 and rotate it. Use the anti-slip protrusions on the outer periphery of the operating block to increase the gripping friction, so that the threaded sleeve 13 is screwed in along the external thread of the winding rod 12. The threaded sleeve 13 drives the clamping block 14 to gradually approach the cable on the winding rod 12 until the rubber pad 15 on the clamping block 14 is tightly attached to the cable, so as to fix and store the cable and avoid the cable from being tangled. At this time, the auxiliary seat 17 at the end of the winding rod 12 will block the threaded sleeve 13 from continuing to screw in, preventing the threaded sleeve 13 from falling off the winding rod 12.

[0024] Before welding, the operator operates the welding host 1 through the control panel on the front, presses the control button to start the device, observes the display screen on the control panel, and rotates the adjustment knob to adjust the welding current and voltage to appropriate values ​​according to the material, thickness and other parameters of the scaffold steel footing. After the parameters are set, the welding work on the steel footing can be carried out through the welding gun connected by the welding gun cable 6. During the welding process, the heat generated inside the welding host 1 is discharged through the heat sinks 2 on both sides to ensure stable operation of the device.

[0025] When a lot of dust adheres to the surface of the heat sink 2, affecting the heat dissipation effect, loosen the positioning pin 10 on the sliding plate 91 to separate the positioning pin 10 from the guide shaft 9. Then, push the sliding plate 91 up and down along the axial direction of the guide shaft 9. The sliding plate 91 drives the cleaning brush 92 to move synchronously. The bristles of the cleaning brush 92 rub against the surface of the heat sink 2 to clean the dust on the surface of the heat sink 2. After cleaning, move the sliding plate 91 to a position that does not affect heat dissipation, such as the top or bottom of the heat sink 2, tighten the positioning pin 10 to make it press against the guide shaft 9, fix the sliding plate 91, and complete the cleaning and maintenance of the heat sink 2.
