Description

Technical Field

[0001] This application relates to the field of aerial work platform component manufacturing, and in particular to a welding fixture for a telescopic boom. Background Technology

[0002] Aerial work platforms, also known as lifting work platforms or scissor lifts, are engineering vehicles that use hydraulic or electric systems to lift and lower their booms or platforms to transport personnel and tools to high-altitude work positions. Their core features are safety, efficiency, and maneuverability, making them a viable alternative to traditional scaffolding and suspended platforms.

[0003] The telescopic boom of an aerial work platform is its core working device, determining the height the vehicle can reach, its working range, and its load-bearing capacity. It uses a hydraulic system to drive multiple boom sections to extend and retract sequentially, thus changing the working height.

[0004] Telescopic booms require welding for fixation during production. Due to their long length, a long welding platform is usually required, and the boom is fixed to the welding platform using clamps. Because of the long length of the boom, the existing welding platform occupies a large area, and the space utilization rate is low when welding only a single size boom. Utility Model Content

[0005] To improve the utilization rate of the welding station, this application provides a telescopic arm welding fixture.

[0006] The telescopic boom welding fixture structure provided in this application adopts the following technical solution:

[0007] A welding fixture for a telescopic boom includes a welding table for placing the telescopic boom. Several sets of clamping mechanisms are evenly arranged along the length of the welding table. Each clamping mechanism includes two vertical rods and one horizontal rod. The two vertical rods abut against both sides of the telescopic boom, and the horizontal rod abuts against the top of the telescopic boom. The two vertical rods are arranged parallel to each other on the horizontal rod, and the distance between the two vertical rods and the horizontal rod is adjustable.

[0008] By adopting the above technical solution, the telescopic arm is clamped and fixed around the perimeter of the welding table using a horizontal bar and two vertical bars. Multiple clamping mechanisms clamp and fix the telescopic arm along its length, thus securing it on the welding table and facilitating welding. The adjustable spacing of the vertical bars can accommodate telescopic arms of different sizes, expanding the applicability of the welding platform and increasing its utilization rate.

[0009] Optionally, the horizontal bar and the vertical bar are detachably connected, and the distance between the two vertical bars can be adjusted by replacing the horizontal bar with one of different lengths.

[0010] By adopting the above technical solution, horizontal bars of different lengths can be replaced by disassembling the horizontal bars, thereby adjusting the distance between the two vertical bars, so that the clamping mechanism can be adapted to telescopic arms of different sizes.

[0011] Optionally, one end of the horizontal bar is mounted on one of the vertical bars, and the other end is slidably connected to another vertical bar.

[0012] By adopting the above technical solution, the distance between the two vertical rods can be adjusted by sliding one of the vertical rods, thereby enabling the clamping mechanism to be applicable to telescopic arms of different sizes.

[0013] Optionally, the horizontal and vertical rods are rotatably connected at their joints.

[0014] By adopting the above technical solution, the horizontal and vertical rods of the rotating connection can be easily adjusted in angle, thus making it suitable for telescopic booms with different cross-sectional shapes.

[0015] Optionally, the horizontal bar is threaded with an abutment bolt that penetrates the horizontal bar.

[0016] By adopting the above technical solution, when the horizontal bar cannot abut against the telescopic arm, the abutment bolt can be rotated to abut against the telescopic arm, thereby clamping and fixing the telescopic arm.

[0017] Optionally, one of the vertical rods is threaded with an adjusting bolt, which passes through the vertical rod.

[0018] By adopting the above technical solution, the adjusting bolt can be rotated to abut against the side wall of the telescopic arm, thereby adjusting the abutment degree of the telescopic plate, and can also be applied to telescopic arms with small size differences to improve the applicable range.

[0019] Optionally, the welding table is threaded with a plurality of limiting screws, and the plurality of limiting screws respectively abut against both ends of the telescopic arm in the length direction.

[0020] By adopting the above technical solution, the setting of the limiting screw can restrict the sliding of the telescopic arm on the welding table along the length direction of the welding table, improve the stability during welding, and thus improve the welding accuracy.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The telescopic arm is clamped and fixed around the welding table surface by a horizontal bar and two vertical bars. Multiple clamping mechanisms clamp and fix the telescopic arm along its length, thus fixing it on the welding table and facilitating the welding process. The adjustable spacing of the vertical bars can accommodate telescopic arms of different sizes, improving the applicability of the welding platform and increasing its utilization rate.

[0023] By disassembling the horizontal bar, horizontal bars of different lengths can be replaced, thereby adjusting the distance between the two vertical bars, so that the clamping mechanism can be adapted to telescopic arms of different sizes;

[0024] The distance between the two vertical rods can be adjusted by sliding one of the vertical rods, thus enabling the clamping mechanism to be adapted to telescopic arms of different sizes;

[0025] The setting of the limit screw can limit the sliding of the telescopic arm on the welding table along the length of the welding table, improve the stability during welding, and thus improve the welding accuracy. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Example 1: This application discloses a welding fixture for a telescopic arm, referring to... Figure 1 and Figure 2 The system includes a rectangular welding platform 1, which is formed by connecting several rectangular platforms end to end. The welding platform 1 is used to place the telescopic arm 2. Several sets of clamping mechanisms 3 are evenly arranged along the length of the welding platform 1. Each clamping mechanism 3 includes two vertical rods 4 and one horizontal rod 5. The two vertical rods 4 abut against both sides of the telescopic arm 2, and one end of each vertical rod is detachably fixed to the welding platform 1 by bolts. The horizontal rod 5 abuts against the top of the telescopic arm 2. The ends of the two vertical rods 4 furthest from the welding platform 1 are both installed on the horizontal rod 5. The two vertical rods 4 are set parallel to the horizontal rod 5. The distance between the two vertical rods 4 on the horizontal rod 5 is adjustable. The horizontal rod 5 and the two vertical rods 4 work together with the welding table 1 to clamp and fix the telescopic arm 2 around its perimeter. Multiple clamping mechanisms 3 clamp and fix the telescopic arm 2 along its length, thus fixing the telescopic arm 2 on the welding table 1. This facilitates the welding of the telescopic arm 2. The adjustable distance between the vertical rods 4 can accommodate telescopic arms 2 of different sizes, improving the applicability of the welding platform and thus increasing the utilization rate of the welding table 1.

[0034] Reference Figure 1 and Figure 2 The horizontal bar 5 and the vertical bar 4 are detachably connected. By replacing the horizontal bar 5 with different lengths, the distance between the two vertical bars 4 can be adjusted. The horizontal bar 5 can be replaced with different lengths, thereby adjusting the distance between the two vertical bars 4. This allows the clamping mechanism 3 to be suitable for telescopic arms 2 of different sizes. The connection between the horizontal bar 5 and the vertical bar 4 is rotatably connected. The rotatably connected horizontal bar 5 and vertical bar 4 can easily adjust the angle, thus making it suitable for telescopic arms 2 with different cross-sectional shapes.

[0035] Reference Figure 1 A threaded connection of abutment bolt 6 is provided on the horizontal bar 5. The abutment bolt 6 passes through the horizontal bar 5. When the horizontal bar 5 cannot abut against the telescopic arm 2, the abutment bolt 6 can be rotated to abut against the telescopic arm 2, thereby clamping and fixing the telescopic arm 2.

[0036] Reference Figure 1 One of the vertical rods 4 is threaded with an adjusting bolt 7. The adjusting bolt 7 passes through the vertical rod 4. The adjusting bolt 7 can be rotated to abut against the side wall of the telescopic arm 2, thereby adjusting the abutment degree of the telescopic plate. It can also be used to improve the applicable range in telescopic arms 2 with small size differences.

[0037] Reference Figure 1 and Figure 2 The welding table 1 is threaded with several limiting screws 8, which abut against both ends of the telescopic arm 2 along its length. The limiting screws 8 can restrict the telescopic arm 2 from sliding along the length of the welding table 1, thereby improving the stability during welding and thus improving the welding accuracy. The welding table 1 is also fixed with a pressure plate 9, which is fixed to the welding table 1 by bolts and presses against the bottom plate of the telescopic arm 2 to restrict the lifting of the bottom plate of the telescopic arm 2.

[0038] The implementation principle of this application embodiment is as follows: After installing a vertical rod 4 on the welding table 1, the telescopic arm 2 is placed on the welding table 1 and abuts against the vertical rod 4 installed on the welding table 1. Then, the horizontal rod 5 and the other vertical rod 4 are rotated so that the horizontal rod 5 is horizontally set on the welding table 1, and the other vertical rod 4 is vertically installed on the welding table 1. When the horizontal rod 5 and the other vertical rod 4 can abut against the telescopic arm 2, the telescopic arm 2 is fixed directly by abutting against the telescopic arm 2 through the horizontal rod 5 and the other vertical rod 4. Then, a limiting bolt is installed on the welding table 1 so that the limiting bolt abuts against the telescopic arm. 2. Fix the telescopic arm 2 at both ends along its length, and then weld the telescopic arm 2 using welding equipment. When the horizontal bar 5 cannot directly abut the telescopic arm 2, rotate the abutment bolt 6 to make the abutment bolt 6 abut the telescopic arm 2, thereby fixing the top of the telescopic arm 2. When the other vertical bar 4 cannot directly abut the telescopic arm 2, if the abutment gap is large, replace the horizontal bar 5 to adjust the distance between the vertical bars 4 to abut the telescopic arm 2 and clamp and fix the telescopic arm 2. If the abutment gap is small, rotate the adjusting bolt 7 to make the adjusting bolt 7 abut the telescopic arm 2 and clamp and fix the telescopic arm 2.

[0039] Example 2: The difference between this example and Example 1 is that the distance between the two vertical rods 4 is adjusted differently.

[0040] Reference Figure 3 and Figure 4One end of the horizontal rod 5 is hinged to one of the vertical rods 4, and the other end is slidably connected to another vertical rod 4. The horizontal rod 5 has a sliding groove 10 corresponding to the vertical rod 4. A sliding bolt 11 is threaded onto the vertical rod 4. Tightening the sliding bolt 11 fixes the vertical rod 4 to the horizontal rod 5. Loosening the sliding bolt 11 allows the vertical rod 4 to slide and rotate on the horizontal rod 5. By disassembling the horizontal rod 5, different lengths of horizontal rod 5 can be replaced, thereby adjusting the distance between the two vertical rods 4. This allows the clamping mechanism 3 to be adapted to telescopic arms 2 of different sizes. Adjusting the distance between the two vertical rods 4 by sliding is convenient. Compared to replacing the horizontal rod 5 with different lengths, the stability is poor, but resources are saved.

[0041] The implementation principle of this application embodiment is as follows: After installing a vertical rod 4 on the welding table 1, the telescopic arm 2 is placed on the welding table 1 and abuts against the vertical rod 4 installed on the welding table 1. Then, the horizontal rod 5 and the other vertical rod 4 are rotated so that the horizontal rod 5 is horizontally set on the welding table 1, and the other vertical rod 4 is vertically installed on the welding table 1. When the horizontal rod 5 and the other vertical rod 4 can abut against the telescopic arm 2, the telescopic arm 2 is fixed directly by abutting against the telescopic arm 2 through the horizontal rod 5 and the other vertical rod 4. Then, a limiting bolt is installed on the welding table 1 so that the limiting bolt abuts against the length of the telescopic arm 2. At both ends of the horizontal direction, the telescopic arm 2 is fixed, and then the telescopic arm 2 is welded by welding equipment. When the horizontal bar 5 cannot directly abut against the telescopic arm 2, the abutment bolt 6 is rotated to abut against the telescopic arm 2 to fix the top of the telescopic arm 2. When the other vertical bar 4 cannot directly abut against the telescopic arm 2, if the abutment gap is large, the vertical bar 4 is slid along the horizontal bar 5 to adjust the distance between the vertical bars 4 to abut against the telescopic arm 2 and clamp and fix the telescopic arm 2. If the abutment gap is small, the adjusting bolt 7 is rotated to abut against the telescopic arm 2 to clamp and fix the telescopic arm 2.

Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to this application.
