Description

Technical Field

[0001] This utility model belongs to the field of metal welding technology, and specifically relates to an electric welding equipment for building metal parts. Background Technology

[0002] Building metal parts refer to metal materials and products widely used in the construction field, used to construct building structures, facades, roofs, doors and windows, and decorations. Commonly used electric welding equipment for welding building metal parts includes manual arc welding machines, gas shielded welding machines, and spot welding machines. Among them, gas shielded welding machines use CO2 gas or argon gas as the protective medium, so that the electric arc burns in the protective gas to melt the welding wire and the base material. It is usually composed of welding gun, welding machine, gas supply cylinder, and other components.

[0003] Existing welding equipment for building metal parts uses gas cylinders to supply protective gas. During use, the gas cylinders must be secured to prevent accidents such as leakage and explosion caused by tipping over. However, some operators, due to convenience, weak safety awareness, or lack of suitable gas cylinder securing devices in the environment, often carry out welding operations without securing the gas cylinders. This not only does not comply with the standard procedures but also poses serious safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a welding equipment for building metal parts. Through components such as the main clamping plate, the auxiliary clamping plate, and the support plate, the gas cylinder can be clamped and fixed to one side of the welding machine. The protective cover is linked to the support plate through the vertical plate. The protective cover descends to expose the start-stop switch only when the gas cylinder is placed on the support plate. After the gas cylinder is removed, the protective cover automatically resets and covers the start-stop switch, realizing the mechanical interlock between the start-stop of the equipment and the fixed state of the gas cylinder. This forces workers to operate in compliance with regulations, effectively reduces the risk of gas cylinder tipping, and improves work efficiency.

[0005] The specific technical solution adopted by this utility model is as follows: A welding device for building metal parts includes brake casters fixedly assembled at the bottom of a welding machine. A start / stop switch is electrically connected to one side of the welding machine. A railing is fixedly connected in an equidistant array on one side of the welding machine. Inner support plates are fixedly connected to the inner sidewalls of the two lower railings. A support plate is provided below the inner support plate. A gas cylinder is movably placed on the top of the support plate. Spring columns are symmetrically and elastically connected to the bottom of the inner support plate. The inner support plate is elastically connected to the support plate via the spring columns. A vertical plate is fixedly connected to one end of the support plate, located on one side of the welding machine. A protective cover for covering the start / stop switch is fixedly connected to the top of the vertical plate. Rotating plates are rotatably connected to one end of the two vertically arranged railings. Main clamping plates for clamping the gas cylinder are symmetrically and fixedly connected to one side of the welding machine. Secondary clamping plates for clamping the gas cylinder are fixedly connected to the inner sidewalls of the rotating plates.

[0006] The two railings located on the same side are fixedly connected by a first guard plate, which is used to cover the gap between the two railings to form a continuous protective surface to block external objects from entering.

[0007] The bottom of the two lower railings are fixedly connected to an extension plate, which is used to cover the gap between the railing and the ground to form a continuous protective surface to prevent external objects from entering.

[0008] The two rotating plates are fixedly connected by a connecting plate, and the support plate is fixedly connected to a second protective plate at the end opposite to the vertical plate.

[0009] One end of one of the rotating plates is rotatably connected to a rotating rod, and a fastening plate is fixedly connected to the outer wall of the rotating rod.

[0010] One end of one of the railings is fixedly connected to a locking post for engaging and securing the locking plate.

[0011] The technical effects achieved by this utility model are as follows: the gas cylinder can be clamped and fixed to one side of the welding machine through the main clamping plate, the auxiliary clamping plate, the support plate and other components. The protective cover is linked with the support plate through the vertical plate. The protective cover will descend to expose the start and stop switch only when the gas cylinder is placed on the support plate. After the gas cylinder is removed, the protective cover will automatically reset and cover the start and stop switch, realizing the mechanical interlock between the start and stop of the equipment and the fixed state of the gas cylinder. This will force workers to operate in compliance with regulations, effectively reduce the risk of gas cylinder tipping, and improve work efficiency. Attached Figure Description

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figures 1-5 As shown, a welding equipment for building metal parts includes brake casters 101 fixedly assembled at the bottom of a welding machine 1. A start / stop switch 102 is electrically connected to one side of the welding machine 1. Guardrails 103 are fixedly connected in an equidistant array on one side of the welding machine 1. Two guardrails 103 on the same side are fixedly connected by a first guard plate 104, which covers the gap between the two guardrails 103 to form a continuous protective surface to prevent external objects from entering. Inner support plates 111 are fixedly connected to the inner walls of the two lower guardrails 103. Extension plates 118 are fixedly connected to the bottom of the two lower guardrails 103 to cover the gap between the guardrails 103 and the ground, forming a continuous protective surface to prevent external objects from entering. A support plate 113 is provided below the inner support plate 111, and a gas cylinder 2 is movably placed on the top of the support plate 113. Spring columns 112 are symmetrically and elastically connected to the bottom of the inner support plate 111. The spring column 112 is elastically connected to the support plate 113. A vertical plate 115 is fixedly connected to one end of the support plate 113 and to one side of the welding machine 1. A protective cover 116 for covering the start / stop switch 102 is fixedly connected to the top of the vertical plate 115. A rotating plate 105 is rotatably connected to one end of two vertically arranged railings 103. A second guard plate 114 is fixedly connected to the end of the support plate 113 opposite to the vertical plate 115. The two rotating plates 105 are fixed by a connecting plate 117. The connection includes a rotating plate 105 with a rotating rod 106 rotatably connected to one end, a fastening plate 107 fixedly connected to the outer wall of the rotating rod 106, a fastening post 108 fixedly connected to one end of a railing 103 for fastening the fastening plate 107, a main fastening plate 110 symmetrically fixedly connected to one side of the welding machine 1 for clamping with the gas cylinder 2, and auxiliary fastening plates 109 fixedly connected to the inner side walls of the rotating plate 105 for clamping with the gas cylinder 2.

[0016] Based on the above structure, the start / stop switch 102 is used to start or stop the welding machine 1, and in the attached... Figure 5 The "operation port" marked in the middle is a notch formed by the gap between the railing 103 and the main clamping plate 110, which is used for the operator to reach in and press the start / stop switch 102. The brake caster 101 is a common type of positioning caster in the prior art. By stepping on the paddle on one side of the brake caster 101, the brake pad in the braking assembly is driven to make close contact with the brake disc on the caster, generating friction and braking, thereby keeping the welding machine 1 in a fixed position. When the gas cylinder 2 is not placed on the support plate 113, the protective cover 116 covers the start / stop switch 102. At this time, the start / stop switch 102 cannot be pressed from the "operation port", and the welding machine 1 cannot be started and used. At this time, the second guard plate 114 is also in contact with the bottom of the rotating plate 105 located below. The two sides of the support plate 113 are retracted into the inside of the extension plate 118. The first guard plate 104, the extension plate 118, and the second guard plate 114 surround the outside of the support plate 113, which can to a certain extent prevent the operator from pressing or stepping on the support plate 113 without placing the gas cylinder 2, forcibly opening the start / stop switch 102, rotating the rotating rod 106 to drive the fastening plate 107 to rotate, and the fastening plate 107 is no longer engaged with the locking post 108. Rotating the upper rotating plate 105, the upper rotating plate 105 drives the lower rotating plate 10 through the connecting plate 117. 5. Rotate together, placing gas cylinder 2 on pallet 113 so that it lowers to the ground. At the same time, the arc-shaped sidewall of the main locking plate 110 is pressed against half of the outer wall of gas cylinder 2, and the spring column 112 extends simultaneously. When pallet 113 lowers, it drives vertical plate 115 and protective cover 116 to lower together. Protective cover 116 no longer covers start / stop switch 102. At this time, you can put your hand into the "operation port" to press start / stop switch 102 to start welding machine 1. Rotate rotating plate 105 and rotating rod 106 so that locking plate 107 is locked with locking column 108. As rotating plate 105 rotates, the arc-shaped sidewall of auxiliary locking plate 109 is pressed against the other half of the outer wall of gas cylinder 2. The clamping plate 110 and the auxiliary clamping plate 109 simultaneously clamp and fix the gas cylinder 2. This utility model can clamp and fix the gas cylinder 2 to one side of the welding machine 1 through the main clamping plate 110, the auxiliary clamping plate 109, the support plate 113 and other components. The protective cover 116 is linked with the support plate 113 through the vertical plate 115. The protective cover 116 descends to expose the start-stop switch 102 only when the gas cylinder 2 is placed on the support plate 113. After the gas cylinder 2 is removed, the protective cover 116 automatically resets to cover the start-stop switch 102, realizing the mechanical interlock between the start-stop of the equipment and the fixed state of the gas cylinder 2, thereby forcibly constraining the worker to operate in compliance with regulations, effectively reducing the risk of the gas cylinder 2 tipping over, and improving work efficiency.

[0017] The working principle of this utility model is as follows: the start / stop switch 102 is used to start or stop the welding machine 1, and in the attached... Figure 5The "operation port" marked in the middle is a notch formed by the gap between the railing 103 and the main clamping plate 110, which is used for the operator to reach in and press the start / stop switch 102. The brake caster 101 is a common type of positioning caster in the prior art. By stepping on the paddle on one side of the brake caster 101, the brake pad in the braking assembly is driven to make close contact with the brake disc on the caster, generating friction and braking, thereby keeping the welding machine 1 in a fixed position. When the gas cylinder 2 is not placed on the support plate 113, the protective cover 11 With the six start / stop switches 102 covered, they cannot be pressed through the "operation port," and the welding machine 1 cannot be started. At this time, the second protective plate 114 is also in contact with the bottom of a rotating plate 105 located below. The sides of the support plate 113 are retracted into the inside of the extension plate 118. The first protective plate 104, extension plate 118, and second protective plate 114 surround the outside of the support plate 113, which can, to a certain extent, prevent operators from pressing the support plate 113 without placing the gas cylinder 2, thus hindering them from doing so. Alternatively, stepping on the switch 102 forcibly activates the start / stop switch, rotating the rotating rod 106 to rotate the locking plate 107. The locking plate 107 then stops engaging with the locking post 108. Rotating the upper rotating plate 105 causes the lower rotating plate 105 to rotate together via the connecting plate 117, placing the gas cylinder 2 on the support plate 113 to lower it to the ground. Simultaneously, the arc-shaped sidewall of the main locking plate 110 is pressed against half of the outer wall of the gas cylinder 2, and the spring post 112 extends. As the support plate 113 descends... When lowered, the vertical plate 115 and the protective cover 116 are lowered together. The protective cover 116 no longer covers the start / stop switch 102. At this time, you can put your hand into the "operation port" and press the start / stop switch 102 to start the welding machine 1. Rotate the rotating plate 105 and the rotating rod 106 to make the fastening plate 107 fasten with the locking column 108. As the rotating plate 105 rotates, the arc-shaped side wall of the auxiliary locking plate 109 is tightly attached to the other half of the outer wall of the gas cylinder 2. The main locking plate 110 and the auxiliary locking plate 109 simultaneously clamp and fix the gas cylinder 2.

[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
