Description

Technical Field

[0001] The invention relates to the technical field of high-altitude welding vehicles, and in particular to a walking high-altitude welding operation vehicle. Background Art

[0002] At present, scenes that require high-altitude welding operations (such as welding on the top of steel structure workshops, welding of aerial pipelines of environmental protection equipment, welding parts on the top of large equipment and shipbuilding) all belong to the category of high-altitude welding. At present, there are mainly two ways to complete this type of welding work: one is to build a frame with manual welding; the other is to lay welding tracks and use welding trolleys for welding. The first method has low welding efficiency, poor weld consistency, low welding quality, extremely high labor intensity for welders, low safety of workers working at high altitudes and high labor costs; it requires a climbing vehicle or building a steel frame, and welders bring welding equipment to high altitudes for manual welding operations. The second method is for certain specific welds, which can effectively improve welding efficiency and welding quality to a certain extent, replace welders, and liberate welders, but it also requires a large number of welding auxiliary work such as laying tracks, installing special welding machines, etc. in advance. A lot of manufacturing time is spent on welding auxiliary work, and the welds are highly targeted and limited in application.

[0003] Therefore, it is necessary to develop a kind of walking type high-altitude welding operation vehicle, to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a walking type high-altitude welding work vehicle, which is not only flexible, but also can effectively replace workers to perform high-altitude welding work, thereby ensuring the safety of workers during operation.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A walking high-altitude welding work vehicle comprises a work vehicle and a touch controller, wherein the work vehicle comprises a moving vehicle, a chassis is provided on the moving vehicle, a crank mechanism is rotatably connected to the chassis, the crank mechanism comprises a supporting part, a first crank arm, a first connecting part, a second connecting part, and a second crank arm, the supporting part is rotatably connected to one end of the first crank arm through the first connecting part, the other end of the first crank arm is rotatably connected to the second crank arm through the second connecting part, the other end of the second crank arm is rotatably connected to the first connecting arm, the other end of the first connecting arm is rotatably connected to the second connecting arm, and the other end of the second connecting arm is rotatably connected to a welding robot.

[0006] Specifically, the welding robot includes a welding gun and a welding power source. A visual sensor is provided at the lower end of the welding gun, and the visual sensor is electrically connected to the wireless control module.

[0007] Specifically, a wireless control module is electrically connected to the welding power source, and the touch controller is wirelessly connected to the wireless control module.

[0008] Specifically, the wireless control module is electrically connected to the mobile vehicle controller, the welding robot controller and the articulated arm mechanism controller.

[0009] The beneficial effects of the present invention are: The setting of the crank mechanism can work stably in a complex and changeable high-altitude environment. They are not affected by external factors such as wind and temperature, and can ensure the smooth progress of welding operations; by setting up a wireless control module, the welding voltage, current and wire feeding speed can be kept constant, reducing the impact of human factors on welding quality. This constant welding parameter ensures the stability and consistency of weld quality.

[0010] Since there is no direct personnel involved in high-altitude welding during the welding process, this application also reduces the risk of workers being injured due to welding operations and improves the safety of operations.

[0011] This application can work continuously and stably without being restricted by worker fatigue and rest time, thus greatly improving welding efficiency.

[0012] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

[0015] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] See also Figure 1 The present invention provides a walking high-altitude welding work vehicle, including a work vehicle and a touch controller. The work vehicle includes a moving vehicle 1, a chassis 2 is provided on the moving vehicle 1, and a crank mechanism 3 is rotatably connected to the chassis 2. The crank mechanism 3 includes a support portion 301, a first crank arm 302, a first connecting portion 303, a second connecting portion 304, and a second crank arm 305. The support portion 301 is rotatably connected to one end of the first crank arm 302 through the first connecting portion 303, and the other end of the first crank arm 302 is rotatably connected to the second crank arm 305 through the second connecting portion 304. The other end of the second crank arm 305 is rotatably connected to the first connecting arm 4. The other end of the first connecting arm 4 is rotatably connected to the second connecting arm 401, and the other end of the second connecting arm 401 is rotatably connected to the welding robot 5.

[0020] Specifically, the welding robot 5 includes a welding gun 501 and a welding power source 502. A visual sensor 503 is provided at the lower end of the welding gun 501. The visual sensor 503 can observe the position to be welded in real time and detect the weld after welding.

[0021] Specifically, the welding power source 502 is electrically connected to a wireless control module, and the touch controller is wirelessly connected to the wireless control module.

[0022] Specifically, the wireless control module is electrically connected to the mobile vehicle controller, the welding robot controller and the articulated arm mechanism controller.

[0023] Specifically, the mobile vehicle controller can stop and start the mobile vehicle 1 and plan the travel path of the mobile vehicle 1; the articulated arm mechanism controller can control the lifting height and direction of the articulated arm mechanism 3; the welding robot controller can control the current, voltage and wire feeding speed during welding.

[0024] When in use, the work vehicle is moved to the lower part of the place where welding is required, and the crank arm mechanism 3 is raised to the height required for welding. The crank arm mechanism 3 rotates the chassis 2 to align the welding gun 501 of the welding robot 5 with the position required for welding. The position required for welding is observed by the visual sensor 503. After the welding voltage, current and wire feeding speed are determined, welding is performed. After welding is completed, the welding gun 501 is turned off, and the weld after welding is observed to determine whether it is qualified. If it is unqualified, the welding is repeated. After passing the test, the crank arm structure is lowered to the initial position, and the operation is driven to leave.

[0025] In summary, the setting of the crank mechanism can work stably in a complex and changeable high-altitude environment. They are not affected by external factors such as wind and temperature, and can ensure the smooth progress of welding operations; by setting up a wireless control module, the welding voltage, current and wire feeding speed can be kept constant, reducing the impact of human factors on welding quality. This constant welding parameter ensures the stability and consistency of weld quality.

[0026] Since there is no direct personnel involved in high-altitude welding during the welding process, this application also reduces the risk of workers being injured due to welding operations and improves the safety of operations.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
