Description

Technical Field

[0001] The utility model belongs to the technical field of welding devices, and specifically relates to a welding maintenance device. Background Technique

[0002] A welding maintenance device is a device that connects metal parts together by heating and melting metals, and is commonly used in various fields. For example, in coal mine equipment, it is necessary to regularly overhaul and maintain the equipment. During the overhaul and maintenance, the welding maintenance device is one of the essential devices.

[0003] At present, there are many welding devices on the market, such as welding machines and welding torches. Among them, a welding torch is a handheld welding tool, mainly composed of a housing, a gun head, an air circuit system, and multiple conductive elements. The gun head is located at the front end of the welding torch and participates in the welding process. Cooperating with components such as a nozzle and a contact tip inside it, it delivers welding current and welding materials to the welding site.

[0004] However, the gun heads of most welding torches are exposed. When welding is completed, since the gun head directly contacts the arc and high-temperature metal slag during welding, its surface will remain at a relatively high temperature, and it is easy to cause scalding accidents. Moreover, when the welding torch is not in use, under the action of external environments and physical factors, such as humidity, corrosion, impact, etc., the gun head is likely to be damaged. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model proposes a welding maintenance device.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A welding maintenance device described in the utility model includes a welding torch frame. One end of the welding torch frame is provided with a gun head, and a handle is installed at the bottom of one end of the welding torch frame. A plurality of groups of sliding grooves are circumferentially formed at one end of the welding torch frame, and a sliding ring is elastically connected inside the sliding groove through a first spring; an electromagnet is provided at a position opposite to the sliding ring at one end of the welding torch frame; a protective cylinder is fixedly connected to one end of the sliding ring; a first screw is installed inside one side of the sliding ring, and one end of the first screw penetrates the inner wall of the sliding ring and abuts against the surface of the welding torch frame; a sensor is installed at the handle; a plurality of groups of air inlet holes are circumferentially formed at one end of the protective cylinder, and an air delivery shell is hermetically sleeved outside the air inlet holes; an air pump is embedded at one end of the welding torch frame, and the output end of the air pump is communicated with the inside of the air delivery shell through an air pipe.

[0007] Preferably, one end of the bottom of the welding torch frame is hinged to the handle through a rotating shaft; a plurality of groups of through holes are circumferentially formed at both the handle and one end of the welding torch frame, and second screws are arranged inside the through holes.

[0008] Preferably, a sliding rod is slidably connected inside one side of the handle, and a second spring is sleeved on the sliding rod; one end of the sliding rod away from the handle is fixedly connected with a protective plate, and extension plates slidably penetrate through both ends inside the protective plate.

[0009] Preferably, multiple groups of guiding frames are installed at one end of the welding torch frame and on the outer wall of the protective cylinder, and the air pipe slidably penetrates through the inside of the guiding frames; multiple groups of balls are arranged around the inside of the guiding frames.

[0010] Preferably, rubber strips are arranged on the opposite surfaces of both sides of one end of the extension plate, and the rubber strips are in contact with the inside of the protective plate.

[0011] Preferably, a handle is installed at the end of the welding torch frame away from the gun head, and a rubber pad is arranged on the surface of the handle.

[0012] The beneficial effects of the present utility model:

[0013] 1. The present utility model provides a welding repair device. During welding, the electromagnet is in an on state. Slide the sliding ring so that the electromagnet magnetically fixes it. At this time, there is a certain distance between the protective cylinder and the gun head, which does not interfere with the welding operation. When welding is completed, the electromagnet is powered off. At this time, the sliding ring moves away from the electromagnet under the restoring force of the first spring, driving the entire protective cylinder to move towards the gun head, covering the gun head with its internal space, reducing the occurrence of scalding accidents caused by the residual high temperature on the surface of the gun head, and the gun head is located inside the protective cylinder to reduce damage to the gun head caused by the external environment. At the same time, the sensor is located at the handle. When the welder holds the handle, the sensor contacts the welder's hand, controlling the electromagnet to turn on. When the welder releases the handle, the sensor loses the contact signal, controlling the electromagnet to turn off, triggering the automatic covering of the protective cylinder. When the device is placed or transported for a long time, by tightening the first screw, the protective cylinder is fixed to the welding torch frame at this time, reducing the risk of the protective cylinder sliding on the surface of the welding torch frame when being impacted, protecting the gun head from being exposed, and reducing the damage or injury that may be caused by the gun head being exposed to impacts;

[0014] 2. The present utility model provides a welding repair device. The air pump transports air into the air delivery shell, and then evenly blows it towards the gun head through the air inlet holes formed around one end of the protective cylinder to achieve a cooling effect, accelerating the heat dissipation of the gun head and enabling it to return to the normal temperature faster, thereby shortening the downtime for repair.

[0026] During operation, the slip ring 5 is made of iron. During welding, the electromagnet 6 is in the on state. Slide the slip ring 5 so that the electromagnet 6 magnetically attracts and fixes it. At this time, the protective cylinder 7 keeps a certain distance from the gun head 2, which does not interfere with the welding operation.
