Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary tools, and in particular to a portable welding slag receiver. Background Technology

[0002] During the welding of steel beams, welding slag will fall off. The temperature of the welding slag is very high (the temperature of the welding slag produced at the welding point can reach 1000 degrees Celsius) and it has high chemical reactivity. It can easily cause a fire when it comes into contact with flammable materials. For example, in the construction area, the residual machine oil of various construction equipment mixed with coal dust is highly flammable. When it comes into contact with the welding slag, the remaining sparks may cause a fire. Therefore, welding slag collection buckets are needed to collect the welding slag during the welding process to prevent the welding slag from falling from a height and causing a safety accident. Traditional welding slag catchers are typically made of galvanized iron sheets. They are flat in shape, with wire or chain connections at the four corners. To use, the catcher is simply hung in a pre-set position. However, this type of catcher presents several problems: First, the galvanized iron sheet is rigid and cannot be stored, making it inconvenient to carry. Second, the fixed area of ​​the galvanized steel sheet prevents adjustment of the contact area according to the size of the workpiece, resulting in low slag collection rate. Third, the catcher must be installed on the workpiece. Since workpieces vary in size, the catcher's fixed size limits its application. When the workpiece is larger or smaller, it cannot be connected, restricting its use. Furthermore, the inability to adjust the distance between the workpiece and the contact area affects welding convenience and quality. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that the purpose, technical solution and advantages of the present invention will be clearer. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] refer to Figure 1 The portable welding slag receiver of an exemplary embodiment of this utility model includes: Adjustable support rod 1 is used to connect to the member to be welded according to the width of the member to be welded; The adjustable frame 2 includes a vertical rod 21 and an umbrella-shaped keel 22. The umbrella-shaped keel 22 is connected to the vertical rod 21 and is used to expand or retract relative to the vertical rod 21 to adjust the fire contact area. The vertical rod 21 is movably connected to the adjustable support rod 1. The welding torch pad 3 is connected to the umbrella-shaped keel 22 and is used to collect the welding slag generated during the welding process. The welding torch pad 3 unfolds or retracts together with the umbrella-shaped keel 22.

[0025] The adjustable support rod 1 includes a first support rod 11, a second support rod 12, and a tie rod 13. The first support rod 11 and the second support rod 12 are parallel to each other. The first end of the tie rod 13 is perpendicularly connected to the first support rod 11, and the second end of the tie rod 13 passes through the second support rod 12, so that the tie rod 13 and the second support rod 12 are movably connected. This allows the distance between the first support rod 11 and the second support rod 12 to be adjusted according to the width of the rod to be welded, making the portable slag receiver suitable for rods of different widths and improving the flexibility of the portable slag receiver in various applications.

[0026] In a preferred embodiment of this invention, a first connecting rod 14 is provided on the first support rod 11, and the first connecting rod 14 and the tie rod 13 are parallel to each other; a second connecting rod 15 is provided on the second support rod 12, and the second connecting rod 15 and the tie rod 13 are parallel to each other; a first sliding groove 141 is provided along the length direction of the first connecting rod 14 (see reference). Figure 1 , Figure 2 The second connecting rod 15 extends into the first sliding groove 141. Adjusting the tie rod 13 allows the first connecting rod 14 to slide relative to the second connecting rod 15, thereby adjusting the distance between the first support rod 11 and the second support rod 12. The first connecting rod 14 and the second connecting rod 15 can improve the structural strength of the adjustable support rod 1 itself, improve the deformation resistance of the adjustable support rod 1, and thus improve the reliability of the adjustable support rod 1 during operation.

[0027] Furthermore, a second sliding groove 142 is provided along the length of the first connecting rod 14, and the second sliding groove 142 is connected to the first sliding groove 141. A first baffle 16 is provided at the end of the first connecting rod 14 away from the first support rod 11, and a second baffle 17 is provided at the end of the second connecting rod 15 away from the second support rod 12. During the sliding process of the first connecting rod 14 relative to the second connecting rod 15, the first baffle 16 and the second baffle 17 work together to prevent the first connecting rod 14 from sliding out of the second connecting rod 15, thus ensuring the reliability of the connection between the first connecting rod 14 and the second connecting rod 15. The width of the second baffle 17 is smaller than the width of the second slide groove 142, so that the first connecting rod 14 can slide smoothly relative to the second connecting rod 15. The first baffle 16 is detachably connected to the first connecting rod 14 by screws, and the second baffle 17 is welded to or detachably connected to the second connecting rod 15 by screws. After the second baffle 17 and the second connecting rod 15 are inserted into the first connecting rod 14 together, the first baffle 16 is connected to the first connecting rod 14. Alternatively, after the first baffle 16 is connected to the first connecting rod 14, the second connecting rod 15 is inserted into the first connecting rod 14, and then the second baffle 17 is inserted into the first connecting rod 14 from the second slide groove 142 and connected to the second connecting rod 15. The first connecting rod 14 and the tie rod 13 are separated by a certain distance (e.g., 2~5cm) to prevent interference between the installation of the first connecting rod 14 and the tie rod 13, which would affect the reliability of the adjustable support rod 1.

[0028] In a preferred embodiment of this invention, the first support rod 11 is welded to or detachably connected to the tie rod 13. When detachably connected, a thread can be provided at the end of the tie rod 13 near the first support rod 11, and a threaded hole can be provided on the first support rod 11, allowing the tie rod 13 and the first support rod 11 to be threadedly connected. Alternatively, a connector 110 can be provided on the first support rod 11. The connector 110 is a hollow cylindrical structure, allowing the tie rod 13 and the connector 110 to be inserted or threadedly connected. The tie rod 13 also has threads along its length. A circular through hole is provided at the connection point between the second support rod 12 and the tie rod 13. The diameter of the circular through hole is larger than the diameter of the tie rod 13. After the tie rod 13 passes through the circular through hole on the second support rod 12, a nut connects the tie rod 13 and the second support rod 12. Adjusting the position of the nut on the tie rod 13 allows the tie rod 13 to slide relative to the second support rod 12, thereby adjusting the distance between the first support rod 11 and the second support rod 12.

[0029] In a preferred embodiment of this invention, the second support rod 12 is movably connected to the vertical rod 21, which allows adjustment of the distance between the bottom of the vertical rod 21 and the rod to be welded, making the portable slag receiver suitable for rods of different heights and sizes, and further improving the flexibility of the portable slag receiver in various applications.

[0030] The second support rod 12 has one or more first connecting holes 120 (see reference) along its length. Figure 3 Setting multiple first connecting holes 120 can improve the stability of the connection between the second support rod 12 and the vertical rod 21. Multiple second connecting holes 210 are provided along the length of the vertical rod 21. The second support rod 12 and the vertical rod 21 are connected by bolts. During the connection process between the second support rod 12 and the vertical rod 21, the second connecting holes 210 at different positions on the vertical rod 21 are aligned with one of the first connecting holes 120 on the second support rod 12. This can adjust the distance between the bottom of the vertical rod 21 and the rod to be welded 4. Then, bolts are used to simultaneously pass through the aligned first connecting holes 120 and second connecting holes 210 to connect and fix the second support rod 12 and the vertical rod 21.

[0031] The vertical rod 21 is also provided with an adjustment groove 211 (see reference). Figure 1 The adjusting groove 211 can replace the second connecting hole 210.

The vertical rod 21 passes through the third sliding groove into the second support rod 12 and slides along the second support rod 12. After the vertical rod 21 passes through the second support rod 12, the bolt passes through the first connecting hole 120 on the second support rod 12 and the adjusting groove 211 on the vertical rod 21 at the same time. Adjusting the nut on the adjusting bolt allows the vertical rod 21 to slide or be fixed relative to the second support rod 12. When the adjusting groove 211 is provided on the vertical rod 21, the vertical rod 21 may not be inserted into the second support rod 12. Figure 3 The connection between the second support rod 12 and the vertical rod 21 is such that the surface of one side of the adjusting groove 211 is fitted to the surface of one side of the first connecting hole 120, so that the bolt passes through the first connecting hole 120 and the adjusting groove 211 at the same time. The nut on the adjusting bolt is used to make the vertical rod 21 slide or be fixed relative to the second support rod 12.

[0032] The umbrella-shaped keel 22 includes multiple sets of umbrella ribs 220, which are arranged circumferentially around the vertical rod 21. Each set of umbrella ribs 220 includes a first umbrella rib 2201 and a second umbrella rib 2202. The first umbrella rib 2201 is hinged to the vertical rod 21, the first end of the second umbrella rib 2202 is hinged to the first umbrella rib 2201, and the second end of the second umbrella rib 2202 is hinged to an adjusting ring 23. The adjusting ring 23 is slidably mounted on the vertical rod 21. As the adjusting ring 23 slides back and forth along the vertical rod 21, the umbrella ribs 220 can be opened or closed. Bolts 24 are also provided on the adjusting ring 23. Adjusting the bolts 24 can fix the adjusting ring 23 to the vertical rod 21, thereby adjusting the opened state of the umbrella-shaped keel 22, making the portable welding slag receiver suitable for different welding spaces.

[0033] In a preferred embodiment of this invention, the welding torch pad 3 is made of graphite fiber. The welding torch pad 3 has tensile elasticity and low thermal conductivity, and is resistant to high temperatures. It can effectively absorb the heat generated during the welding process and prevent welding slag from splashing and falling. The welding torch pad 3 is fixedly connected to the first umbrella rib 2201. For example, the welding torch pad 3 and the first umbrella rib 2201 can be fixedly connected by a fire-resistant adhesive or a fire-resistant fiber rope. The fire-resistant adhesive or fire-resistant fiber rope has excellent fire resistance properties and can ensure the reliability of the connection between the welding torch pad 3 and the first umbrella rib 2201.

[0034] refer to Figure 4 The method of using the portable welding slag receiver of this utility model is as follows: Based on the width of the installed member 4 to be welded, adjust the position of the nut on the tie rod 13 so that the tie rod 13 drives the first support rod 11 to slide relative to the second support rod 12, so that the distance between the first support rod 11 and the second support rod 12 is larger than the width of the member 4 to be welded. Then, the adjustable support rod 1 is engaged on the member 4 to be welded, with the end of the adjustable support rod 1 close to the member 4 to be welded. Continue to adjust the tie rod 13 so that the first support rod 11 and the second support rod 12 clamp the member 4 to be welded. Then, adjust the nut on the tie rod 13 to fasten the adjustable support rod 1 to the member 4 to be welded.

[0035] According to the height of the member 4 to be welded, when the distance between the bottom of the vertical rod 21 and the member 4 to be welded does not meet the welding requirements and will interfere with the welding of the bottom of the member 4 to be welded, adjust the nut at the connection between the second support rod 12 and the vertical rod 21 to adjust the vertical rod 21 so that the distance between the bottom of the vertical rod 21 and the member 4 to be welded meets the welding requirements. After the adjustment is completed, continue to adjust the nut at the connection between the second support rod 12 and the vertical rod 21 to fix the second support rod 12 and the vertical rod 21.

[0036] Open the welding torch pad 3 to make it unfolded. According to the width of the rod 4 to be welded, adjust the adjusting ring 23 on the vertical rod 21 to adjust the unfolded state of the umbrella-shaped keel 22, thereby adjusting the unfolded width of the welding torch pad 3. When the unfolded width of the welding torch pad 3 is larger than the width of the rod 4 to be welded and can cover the end of the installed rod 4 near the adjustable support rod 1, adjust the bolt 24 on the adjusting ring 23 to fix the adjusting ring 23 on the vertical rod 21 so that the welding slag generated during the welding process enters the unfolded range of the welding torch pad 3.

[0037] After the portable slag receiver is installed, align another rod 4 to be welded with the installed rod 4, and then weld at the aligned position. The slag generated during the welding process enters the welding torch pad 3 to prevent the slag from falling from a height and causing a safety accident. After the welding is completed, a weld 5 is formed at the welding position.
