Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy ladder tube insertion technology, and in particular to a tube insertion device for the production of aluminum alloy ladders. Background Technology

[0002] Aluminum alloy ladders are vertical climbing tools used in the wind power industry. They serve as tools for people to climb towers, mounting carriers for slide rails in fall protection systems, and guiding tools for tower hoists. Currently, the existing pipe installation methods are manual and semi-automatic pipe installation.

[0003] Manual pipe threading is inefficient, while semi-automatic pipe threading typically involves threading individual square tubes sequentially. This requires ensuring that the displacement of the ladder body is precise enough. Even slight displacement can cause an abnormal insertion position of a square tube, leading to threading failure. Utility Model Content

[0004] This utility model discloses a tube-threading device for the production of aluminum alloy ladders, which aims to solve the technical problem that semi-automatic tube threading generally involves sequentially threading single square tubes, and it is necessary to ensure that the displacement of the ladder body is accurate enough. If there is any slight displacement, it will cause the insertion position of a certain square tube to be abnormal, resulting in tube threading failure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tube-threading device for producing aluminum alloy ladders includes a clamping seat, a top integration mechanism, a feeding mechanism, and a limiting mechanism. The feeding mechanism includes: a base with multiple air rods fixedly connected to its top outer wall; a side support plate with the output ends of the multiple air rods simultaneously fixedly connected to one side outer wall; and multiple abutment rods simultaneously fixedly connected to one side outer wall. The limiting mechanism includes: a base frame, on which multiple clamping plates are fixedly connected at equal intervals on its top outer wall; two horizontal plates are fixedly connected to the outer walls on both sides of the multiple clamping plates; a base plate, which is movably inserted into the base frame, and on which multiple clamping plates are fixedly connected at equal intervals on its top outer wall; an electric guide rail, which is fixedly connected to the top outer wall of the base, and the base frame is movably connected to the electric guide rail; and two limiting abutments, which are simultaneously fixedly connected to the top outer wall of the base.

[0006] By setting a limiting mechanism, as the electric guide rail moves the base plate and base frame until the base frame contacts the limiting abutment on one side, the base plate continues to move, which can stably clamp the two sides of the square tube by clamping plate one and clamping plate two, thereby achieving simultaneous fixation of multiple square tube positions. This facilitates the feeding of square tubes and also enables the simultaneous threading of multiple square tubes, improving threading efficiency and accuracy.

[0007] In a preferred embodiment, the top integration mechanism includes: a plurality of cover plates, which are respectively movably attached to the top outer walls of clamp plate one and clamp plate two; and a hinge, which is fixedly connected to clamp plate one and cover plates. The top integration mechanism also includes: a horizontal plate, located on one side of the base frame; and two uprights, fixedly connected to both ends of the horizontal plate, with their bottom ends fixedly connected to the top outer wall of the base. The top integration mechanism also includes: multiple oblique waist-shaped grooves, equidistantly arranged through one side of the horizontal plate; multiple sliders, respectively fixedly connected to one side of the outer wall of the cover plate, and the multiple sliders are respectively movably connected within the multiple oblique waist-shaped grooves.

[0008] The top integration mechanism is equipped with a cover plate that covers the top of each set of clamping plates one and two to press the top of the square tube, so as to prevent the square tube from tilting longitudinally and making it difficult to pass through the tube. At the same time, the cover plate can be automatically opened and closed to facilitate the feeding of the square tube.

[0009] In a preferred embodiment, the limiting mechanism further includes: a second slider, which is fixedly connected to one side outer wall of the base plate and movably connected to the electric guide rail; and two third side support plates, which are symmetrically fixedly connected to the two sides outer walls of the base frame. The limiting mechanism further includes: two side support plates 2, which are symmetrically fixedly connected to the outer walls of both sides of the base plate; and two springs, whose two ends are respectively fixedly connected to the side support plates 2 and 3. The limiting mechanism further includes: a groove, which is disposed on the inner wall of the top of the base, and two limiting brackets are located at both ends of the groove; and a roller, which is fixedly connected to the outer wall of the bottom of the base frame, and the roller rolls in the groove.

[0010] By setting a limiting mechanism, the clamping plate one and clamping plate two are first moved back and forth by the electric guide rail. The spring rebounds due to shaking and squeezing, so that multiple clamping plates two repeatedly collide with the square tube, thereby adjusting the position of the square tube and preventing it from being misaligned. This ensures that the square tube is exactly aligned with the side of the through hole when clamped, thus achieving an automatic correction function.

[0011] As described above, a tube-threading device for aluminum alloy ladder production includes a clamping base, a top integration mechanism, a feeding mechanism, and a limiting mechanism. The feeding mechanism includes: a base with multiple pneumatic rods fixedly connected to its top outer wall; a side support plate, with the output ends of the multiple pneumatic rods simultaneously fixedly connected to one side outer wall of the side support plate; and multiple abutment rods simultaneously fixedly connected to one side outer wall of the side support plate. The limiting mechanism includes: a base frame with multiple clamping plates equidistantly fixedly connected to its top outer wall; two horizontal plates equidistantly connected to the outer walls of the clamping plates; a base plate movably inserted into the base frame, with multiple clamping plates equidistantly fixedly connected to its top outer wall; an electric guide rail fixedly connected to the top outer wall of the base, and the base frame movably connected to the electric guide rail; and two limiting abutment rods simultaneously fixedly connected to the top outer wall of the base. The tube-threading device for aluminum alloy ladder production provided by this utility model has the technical effect of facilitating the feeding of square tubes while simultaneously threading multiple square tubes, improving threading efficiency and accuracy.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] The tube-insertion device disclosed in this utility model is mainly used in the production of aluminum alloy ladders.

[0019] Reference Figures 1-3 A tube-threading device for producing aluminum alloy ladders includes a clamping seat 1, a top integration mechanism 2, a feeding mechanism 3, and a limiting mechanism 4. The feeding mechanism 3 includes: The base 302 has multiple gas springs 301 fixedly connected to its top outer wall; Side support plate 303, the output ends of multiple air rods 301 are simultaneously fixedly connected to one side outer wall of side support plate 303; Multiple abutment rods 304 are simultaneously fixedly connected to one side outer wall of the side support plate 303; Limiting mechanism 4 includes: The base frame 406 has multiple clamping plates 404 fixedly connected at equal intervals to its top outer wall; Two horizontal plates 405 are fixedly connected to the outer walls of both sides of multiple clamping plates 404; The base plate 402 is movably inserted into the base frame 406, and multiple clamping plates 401 are fixedly connected at equal intervals to its top outer wall; The electric guide rail 407 is fixedly connected to the top outer wall of the base 302, and the base frame 406 is movably connected to the electric guide rail 407. Two limiting brackets 408 are simultaneously fixedly connected to the top outer wall of the base 302. The corresponding clamping plates 401 and 404 are grouped together, and the initial distance between them is much larger than the width of the square tube, which facilitates the insertion of the square tube. As the electric guide rail 407 moves the base plate 402 and the base frame 406, the base frame 406 stops moving when it contacts the limiting bracket 408 on one side. The base frame 406 continues to move, which allows the clamping plates 401 and 404 to stably clamp the two sides of the square tube, thereby achieving simultaneous fixation of multiple square tubes. Then, the air rod 301 drives multiple abutments 304 to push the square tube to complete the installation. This not only facilitates the feeding of square tubes, but also enables the simultaneous insertion of multiple square tubes, improving insertion efficiency and accuracy.

[0020] Reference Figure 2 In a preferred embodiment, the limiting mechanism 4 further includes: Slider 2 411 is fixedly connected to one side of the outer wall of the base plate 402, and slider 2 411 is movably connected to the electric guide rail 407; Two side support plates 409 are symmetrically fixed to the outer walls of both sides of the base frame 406.

[0021] Reference Figure 2 In a preferred embodiment, the limiting mechanism 4 further includes: Two side support plates 403 are symmetrically fixed to the outer walls of the two sides of the base plate 402; Two springs 410 are fixedly connected at both ends to side support plate 2 403 and side support plate 3 409, respectively.

[0022] Reference Figure 2 In a preferred embodiment, the limiting mechanism 4 further includes: A groove 413 is provided on the inner top wall of the base 302, and two limiting brackets 408 are located at both ends of the groove 413; Roller 412 is fixedly connected to the bottom outer wall of base frame 406 and rolls in roller groove 413. In limiting mechanism 4, base plate 402 and base frame 406 are movably connected, and spring 410 is provided at the connection between the two. After the square tube is placed between clamping plate 1 401 and clamping plate 2 404 in the open state, clamping plate 1 401 and clamping plate 2 404 are driven to move back and forth by electric guide rail 407. During the movement, they repeatedly touch the limiting bracket 408 on one side. Through shaking and squeezing, spring 410 rebounds. Thus, under the condition that clamping plate 1 401 is relatively stable, multiple clamping plates 2 404 repeatedly collide with the square tube, thereby adjusting the position of the square tube and avoiding its misalignment. This ensures that the square tube corresponds exactly to the side of the tube hole when clamped, realizing the automatic correction function.

[0023] Reference Figure 4 In a preferred embodiment, the top integration mechanism 2 includes: Multiple cover plates 201 are respectively movably attached to the top outer wall of clamp plate 1 401 and clamp plate 2 404. The main purpose is to press the top of the square tube by covering the top of clamp plate 1 401 and clamp plate 2 404 in each group, so as to avoid the square tube from tilting longitudinally and thus making it impossible to pass through the tube smoothly. Hinge 206 is fixedly connected to clamp 401 and cover plate 201.

[0024] Reference Figure 4 In a preferred embodiment, the top integration mechanism 2 further includes: Horizontal plate 203 is located on one side of base frame 406; Two uprights 205 are fixedly connected to both ends of the horizontal plate 203, and their bottom ends are fixedly connected to the top outer wall of the base 302.

[0025] Reference Figure 4 In a preferred embodiment, the top integration mechanism 2 further includes: Multiple oblique waist-shaped grooves 204 are equidistantly arranged through one side of the horizontal plate 203; Multiple sliders 202 are fixedly connected to one side of the outer wall of the cover plate 201, and multiple sliders 202 are movably connected to multiple oblique waist-shaped grooves 204. In the top integration mechanism 2, based on the connection of the hinge 206, and the fact that the sliders 202 on one side of the cover plate 201 can be pulled to move along the oblique waist-shaped grooves 204 during the lateral translation of multiple clamping plates 401, the cover plate 201 can be opened to ensure the feeding of square tubes.

[0026] Working principle: Clamping plates 401 and 404 at corresponding positions are grouped together, and the initial distance between them is much larger than the width of the square tube, which facilitates the insertion of the square tube. As the electric guide rail 407 moves the base plate 402 and the base frame 406, the base frame 406 stops moving when it contacts the limiting abutment 408 on one side. The base frame 406 stops moving, while the base plate 402 continues to move, which allows clamping plates 401 and 404 to stably clamp both sides of the square tube, thereby achieving simultaneous fixation of multiple square tubes. Then, the pneumatic rod 301 drives multiple abutments 304 to push the square tube to complete the installation. This not only facilitates the feeding of square tubes but also enables the simultaneous insertion of multiple square tubes, improving insertion efficiency and accuracy.

[0027] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
