Description

Technical Field

[0001] This utility model relates to the field of container processing technology, specifically an auxiliary welding device for extending the frame of a container transport semi-trailer. Background Technology

[0002] A shipping container is a modular tool that can carry packaged or unpackaged goods for transport and is easy to load and unload using mechanical equipment. Container transport is an important mode of transport in the multimodal transport of international trade goods. Due to its advantages such as high standardization, good sealing, low damage rate, intensification, large scale, liner service, low cost, and high quality, container transport greatly improves the safety and efficiency of cargo transportation.

[0003] Chinese utility model patent CN219053406U, published on May 23, 2023, discloses a container welding fixture, including a first positioning strip, a second positioning strip, and a third positioning strip, which are perpendicular to each other. The first ends of the first, second, and third positioning strips are fixedly connected, and each of the first, second, and third positioning strips includes two perpendicular positioning edges. Each of the first, second, and third positioning strips is equipped with a magnetic component, which can use magnetic force to firmly attach multiple skeleton steel members to be welded to the first, second, and third positioning strips respectively. This allows for rapid positioning of the skeleton steel members of the frame, ensuring their verticality. Moreover, with the help of this fixture, only the welding worker needs to operate it, improving efficiency and saving manpower.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing frame positioning fixtures are fixed on a plane, and then the frame steel is positioned and fixed before welding. This method is not suitable for assembly line-style container welding assistance. Therefore, it is necessary to develop a device that is suitable for assisting in the welding of containers in mid-air. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing frame positioning fixtures, which fix the fixtures on a plane, then position and fix the frame steel, and then weld them, are not suitable for assembly line-style container welding assistance. Therefore, it is necessary to develop a device that can assist in welding containers in mid-air, and to provide an auxiliary welding device for the extended frame of a container transport semi-trailer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses an auxiliary welding device for extending the frame of a container transport semi-trailer, comprising a base plate detachably connected to the ground; a support shaft detachably connected to the base plate; a first nut assembly inserted into a hole on the support shaft; a free shaft sleeved on the first nut assembly; a second nut assembly inserted into the free shaft; a support plate sleeved on the second nut assembly; a slide rail fixedly connected to the upper surface of the support plate; a slider slidably connected to the slide rail; and a limit cover plate detachably connected to the slider.

[0008] Furthermore, the two ends of the support plate are detachably fixed with limit baffles corresponding to the slide rails.

[0009] Furthermore, a limiting sleeve is fitted onto the support shaft; the limiting sleeve is fixedly connected to a vertical limiting plate and an inclined limiting plate.

[0010] The auxiliary welding device for extending the frame of a container transport semi-trailer provided by this utility model has the following beneficial effects:

[0011] 1. This utility model fixes the welding torch between the slider and the limiting cover plate, thereby achieving a precise welding trajectory as the slider moves on the slide rail. Then, the base plate is fixed on the container's moving path, and the height of the support shaft is selected according to the container's size. The free shaft is then tilted to the maximum angle to avoid obstruction. After the container moves to the welding point and stops, the free shaft is pushed to bring the welding torch into contact with the container, and then straight welding is performed along the slide rail. The angle of the support plate can be adjusted by loosening the second nut pair to achieve straight welding at other angles, thereby improving welding efficiency.

[0012] 2. This utility model limits the left rotation angle of the free shaft by using a vertical limiting plate and the right rotation angle by using an inclined limiting plate. Thus, when the container is displaced, the free shaft moves with the welding torch fixed between the slider and the limiting cover to avoid it. When the container stops, the free shaft is pushed to rotate until it contacts the vertical limiting plate to stop the movement. Then, precise straight welding is performed by the displacement of the slider and the slide rail. The tilt angle of the support plate can be adjusted by rotating the second nut pair to achieve non-horizontal straight welding. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, an auxiliary welding device for an extended frame of a container transport semi-trailer includes a base plate 1 detachably connected to the ground; a support shaft 3 detachably connected to the base plate 1; a first nut assembly 4 inserted into a hole in the support shaft 3; a free shaft 5 sleeved on the first nut assembly 4; a second nut assembly 9 inserted into the free shaft 5; a support plate 10 sleeved on the second nut assembly 9; a slide rail 11 fixedly connected to the upper surface of the support plate 10; a slider 12 slidably connected to the slide rail 11; and a limit cover plate 13 detachably connected to the slider 12. A welding torch is inserted between the slider 12 and the limit cover plate 13. The slide rail 11 is fixed in place so that the slider 12 can move on the slide rail 11 to achieve a precise welding trajectory. Then, the base plate 1 is fixed on the container moving path, and the height of the support shaft 3 is selected according to the size of the container. Then, the free shaft 5 is tilted to the maximum angle to avoid obstruction. After the container moves to the welding point and stops, the free shaft 5 is pushed to bring the welding gun into contact with the container. Then, straight welding is performed along the slide rail 11. Then, the second nut pair 9 can be loosened to adjust the angle of the support plate 10 to achieve straight welding at other angles, thereby improving the welding efficiency.

[0022] The two ends of the support plate 10 are detachably fixed with limit baffles 14 corresponding to the slide rails 11. The limit baffles 14 allow the displacement of the slider 12 and the limit cover 13 on the slide rails 11 to be adjusted manually without care, thereby maximizing the welding movement speed and improving the welding efficiency of the container.

[0023] A limiting sleeve 6 is fitted onto the support shaft 3; the limiting sleeve 6 is fixedly connected to a vertical limiting plate 7 and an inclined limiting plate 8. The left rotation angle of the free shaft 5 is limited by the vertical limiting plate 7, and the right rotation angle of the free shaft 5 is limited by the inclined limiting plate 8. Thus, when the container is displaced, the free shaft 5 moves with the welding torch fixed between the slider 12 and the limiting cover plate 13 to avoid it. When the container stops, the free shaft 5 is pushed to rotate until it contacts the vertical limiting plate 7 to stop the movement. Then, precise straight welding is performed by the displacement of the slider 12 and the slide rail 11. The tilt angle of the support plate 10 can be adjusted by rotating the second nut pair 9 to achieve non-horizontal straight welding.

[0024] The limiting sleeve 6 has a corresponding hole and threaded connection to the support shaft 3. By rotating the second fastener 15 in both directions, it contacts the support shaft 3 to adjust the tightness, thereby changing the height of the limiting sleeve 6 on the support shaft 3. This allows for adjustment of the maximum tilt angle of the free shaft 5, thus avoiding the lifting displacement of the container.

[0025] A central tube is fixed to the lower surface of the base plate 1. The base plate 1 can be fixed to the ground by pre-embedded anchor rods through the central tube, so that there are various fixing methods that can be selected according to needs.

[0026] The base plate 1 has holes for inserting multiple first fasteners 2. The base plate 1 can be stably connected and fixed to the ground by the multiple first fasteners 2, and can be disassembled for transfer to adapt to containers of different sizes.
