Description

Technical Field

[0001] This utility model relates to the field of staircase technology, and in particular to an automated welding equipment for staircase frames. Background Technology

[0002] Steel structure staircases are renowned for their fewer support points, high load-bearing capacity, diverse designs, and advanced technology. They are less susceptible to damage from columns, floors, and other structural elements, making them sturdy and robust. The main structural components of a steel structure staircase are the stair columns and the stair frame. Currently, the dimensions of these components vary from building to building, requiring the creation of different tooling and fixtures for welding. Furthermore, the extensive reliance on manual welding results in high costs.

[0003] The existing patent number CN209520495U discloses a prefabricated staircase welding equipment, including a base, a first motor, a first gear disk, a support pile, a first transmission belt, a first rotating disk, a second motor, a second rotating disk, a support plate, a conveyor belt, a second gear disk, a first rotating rod, wheels, a mounting frame, a dust baffle, a third motor, a hydraulic pump, a hydraulic column, a telescopic rod, a fixing buckle, a welding nozzle, a rotating wheel, a suction cup, a drain, a dust box, and a dust box frame. This utility model, through the action of the first and second motors, can realize a mechanism for the welding equipment to perform circumferential lifting, enabling not only linear welding but also circumferential welding.

[0004] The above solution uses a hydraulic pump to control the welding nozzle to weld along the weld seam. It can control the welding depth according to the depth of the weld point, resulting in good welding effect. The dust baffle collects sparks and iron filings, preventing sparks from flying around during welding and avoiding burns to operators. It also reduces dust and ensures a clean welding environment. However, welding produces a lot of smoke that enters the construction room, which degrades the indoor air quality and the surrounding air quality for workers. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated welding equipment for stair frames, comprising: a base plate and a support plate, wherein an outer cover is fixedly connected to the top of the outer surface of the support plate, an exhaust fan is provided on the inner wall of the outer cover, the exhaust fan is located directly above the welding device, a through pipe is fixedly connected to the top of the outer surface of the outer cover, and an activated carbon filter is provided on the inner wall of the through pipe.

[0006] The technical effect of adopting the above-mentioned further solution is that a lot of smoke will be generated during welding. The exhaust fan is started by an external power source to draw the smoke into the inside of the outer cover, and then into the inside of the pipe. The smoke is filtered by an activated carbon filter and then discharged to the outside through the pipe. The length of the pipe can be determined according to the actual site conditions and is not limited.

[0007] In a preferred embodiment, a hydraulic cylinder is fixedly connected to the top of the outer surface of the base plate, a connecting plate is fixedly connected to the top of the outer surface of the hydraulic cylinder, an electric push rod is fixedly connected to the outer surface of the connecting plate, a frame is fixedly connected to one end of the electric push rod, a motor is fixedly connected to the outer surface of the frame, and a threaded rod is fixedly connected to the output end of the motor.

[0008] The technical effect of adopting the above-mentioned further solution is that: the device is pushed to the construction site of the staircase to be welded, and then the hydraulic cylinder is started by an external power source. The hydraulic cylinder pushes the connecting plate to move up and down, which in turn drives the upper frame and the various parts of the outer cover to move up and down. The main purpose is to drive the welding device to move so that welding can be carried out on staircases of different heights.

[0009] In a preferred embodiment, the threaded rod is embedded in the inner wall of the frame via a bearing, and the end of the threaded rod away from the motor is rotatably connected to the inner wall of the frame via a bearing. A limit rod is fixedly connected to the inner wall of the frame.

[0010] The technical effect of adopting the above-mentioned further solution is that the motor is started by an external power source to drive the threaded rod to rotate. At this time, the slider slides on its outer surface under the limit of the limit rod, thereby driving the welding device to move laterally and perform welding.

[0011] In a preferred embodiment, a slider is movably sleeved on the outer surface of the limiting rod and the threaded rod, the support plate is fixedly connected to the top of the outer surface of the slider, and a horizontal plate is fixedly connected to the outer surface of the support plate near its top.

[0012] The technical effect of adopting the above-mentioned further solution is that the electric push rod two is started by an external power source, and the electric push rod two pushes the bottom of the swing plate. At this time, the limit spring rotates horizontally in a semi-circle around one end of the horizontal plate through the rotating rod.

[0013] In a preferred embodiment, a rotating rod is movably embedded inside the horizontal plate, a rocking plate is movably sleeved on the outer surface of the rotating rod, and a welding device is fixedly connected to the outer surface of the rocking plate near its top.

[0014] The technical effect of adopting the above-mentioned further solution is that the angle of the welding device at the top of the limit spring can be adjusted.

[0015] In a preferred embodiment, a limiting spring is fixedly connected to the outer surface of the rocker plate near its bottom, and the end of the limiting spring away from the rocker plate is fixedly connected to the outer surface of the support plate. An electric push rod two is fixedly connected to the outer surface of the support plate, and the electric push rod two is located on one side of the outer surface of the rocker plate.

[0016] The technical effect of adopting the above-mentioned further solution is that, under the limitation of the limiting spring, the limiting spring and the horizontal plate are always in a perpendicular state.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, a lot of smoke is generated during welding. An external power source activates an exhaust fan to draw the smoke into the interior of the outer casing, then into the through-pipe. The smoke is filtered through an activated carbon filter and then discharged outdoors through the through-pipe. The length of the through-pipe is unlimited and can be determined according to the actual site conditions.

[0019] In use, this invention involves pushing the device to the staircase construction site to be welded, then activating the hydraulic cylinder via an external power source. The hydraulic cylinder pushes the connecting plate up and down, which in turn moves the upper frame and outer casing components up and down. This primarily moves the welding device to allow welding at different staircase heights. Simultaneously, an external power source activates the motor, rotating the threaded rod. Under the constraint of the limiting rod, the slider slides on its outer surface, causing the welding device to move laterally and perform welding. The limiting spring ensures that the limiting spring and the horizontal plate remain perpendicular. An external power source activates the electric push rod, pushing the bottom of the swing plate. The limiting spring rotates laterally in a semi-circle around one end of the horizontal plate via the rotating rod. The angle of the welding device at the top of the limiting spring can be adjusted. During welding, different heights, positions, and angles can be achieved, resulting in a wide welding range without the need for manual welding. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Please see Figure 1-4 This utility model provides an automated welding equipment for a stair frame, including: a base plate 101 and a support plate 110. An outer cover 117 is fixedly connected to the top of the outer surface of the support plate 110. An exhaust fan 120 is provided on the inner wall of the outer cover 117. The exhaust fan 120 is located directly above the welding device 116. A through pipe 118 is fixedly connected to the top of the outer surface of the outer cover 117. An activated carbon filter 119 is provided on the inner wall of the through pipe 118. During welding, a lot of smoke will be generated.

The smoke is filtered by the activated carbon filter 119 and then discharged to the outside through the through pipe 118. The length of the through pipe 118 is unlimited and can be determined according to the actual site conditions.

[0028] like Figure 1-4 As shown, a hydraulic cylinder 102 is fixedly connected to the top of the outer surface of the base plate 101. A connecting plate 103 is fixedly connected to the top of the outer surface of the hydraulic cylinder 102. An electric push rod 104 is fixedly connected to the outer surface of the connecting plate 103. A frame 105 is fixedly connected to one end of the electric push rod 104. A motor 106 is fixedly connected to the outer surface of the frame 105. A threaded rod 107 is fixedly connected to the output end of the motor 106. The device is pushed to the stair construction site to be welded. Then, the hydraulic cylinder 102 is started by an external power source. The hydraulic cylinder 102 pushes the connecting plate 103 to move up and down, which in turn drives the upper frame 105 and the various components of the outer cover 117 to move up and down. This mainly drives the welding device 116 to move, which can weld staircases of different heights.

[0029] like Figure 1-4 As shown, the threaded rod 107 is embedded in the inner wall of the frame 105 through a bearing. The end of the threaded rod 107 away from the motor 106 is rotatably connected to the inner wall of the frame 105 through a bearing. The inner wall of the frame 105 is fixedly connected to a limit rod 108. The motor 106 is started by an external power source to drive the threaded rod 107 to rotate. At this time, the slider 109 slides on its outer surface under the limit of the limit rod 108, thereby driving the welding device 116 to move laterally and perform welding.

[0030] like Figure 1-4 As shown, a slider 109 is movably sleeved on the outer surface of the limiting rod 108 and the threaded rod 107. The support plate 110 is fixedly connected to the top of the outer surface of the slider 109. A horizontal plate 114 is fixedly connected to the outer surface of the support plate 110 near its top. The electric push rod 111 is activated by an external power source. The electric push rod 111 pushes the bottom of the rocker plate 113. At this time, the limiting spring 112 rotates horizontally in a semi-circle around one end of the horizontal plate 114 via the rotating rod 115.

[0031] like Figure 1-4 As shown, a rotating rod 115 is movably embedded inside the horizontal plate 114, and a rocking plate 113 is movably sleeved on the outer surface of the rotating rod 115. A welding device 116 is fixedly connected to the outer surface of the rocking plate 113 near its top. The angle of the welding device 116 at the top of the limiting spring 112 can be adjusted.

[0032] like Figure 1-4 As shown, a limiting spring 112 is fixedly connected to the outer surface of the rocker plate 113 near its bottom. The end of the limiting spring 112 away from the rocker plate 113 is fixedly connected to the outer surface of the support plate 110. An electric push rod 111 is fixedly connected to the outer surface of the support plate 110. The electric push rod 111 is located on one side of the outer surface of the rocker plate 113. Under the limitation of the limiting spring 112, the limiting spring 112 and the horizontal plate 114 are always in a perpendicular state.

[0033] Working principle: When in use, the device is pushed to the staircase construction site to be welded. Then, the hydraulic cylinder 102 is started by an external power source. The hydraulic cylinder 102 pushes the connecting plate 103 to move up and down, which in turn moves the upper frame 105 and the outer cover 117 components up and down. This mainly drives the welding device 116 to move, allowing welding to be performed on staircases of different heights. At the same time, the motor 106 is started by an external power source, driving the threaded rod 107 to rotate. At this time, under the limit of the limit rod 108, the slider 109 slides on its outer surface, thereby driving the welding device 116 to move laterally and perform welding. Under the limit of the limit spring 112, the limit spring 112 and the horizontal plate 114 are always in a perpendicular state. The electric push rod 111 is started by an external power source. 111 pushes the bottom of the swing plate 113. At this time, the limiting spring 112 rotates horizontally in a semi-circle around one end of the horizontal plate 114 via the rotating rod 115. At the same time, the angle of the welding device 116 at the top of the limiting spring 112 can be adjusted. When the welding device 116 is welding, welding can be performed at different heights, positions and angles. The welding range is wide and no manual welding is required. At the same time, a lot of smoke will be generated during welding. The exhaust fan 120 is started by an external power source to draw the smoke into the interior of the outer cover 117 and then into the interior of the pipe 118. The smoke is filtered by the activated carbon filter 119 and then discharged to the outside through the pipe 118. The length of the pipe 118 can be determined according to the actual site conditions and is not limited.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
