Description

Technical Field

[0001] This application relates to the field of welding auxiliary device technology, specifically to a retractable welding rod heat preservation cylinder. Background Technology

[0002] Welding is a common processing technique in industrial production, widely used in military, shipbuilding, automobile manufacturing, pressure vessel manufacturing, petrochemical, pipeline, and steel structure manufacturing industries. During welding, the temperature of the welding electrode has a significant impact on the performance of the welded product. Especially in low-temperature environments or when welding thick plates and high-strength steel, preheating and heat preservation of the welding electrode can effectively reduce welding cracks and improve the mechanical properties and crack resistance of the weld. Welding electrode heat preservation cylinders play a vital role as an auxiliary welding device.

[0003] The commonly used welding rod length is 320-400mm. Therefore, the inner cavity of the existing welding rod insulation cylinder needs to be higher than 400mm to facilitate the insulation and storage of the welding rod. However, due to the depth of the welding rod insulation cylinder and the small internal space, it is inconvenient to take out the welding rod during the welding operation. It is necessary to tilt the welding rod cylinder and pour the whole thing out of the cylinder before taking out the required number of welding rods. After use, the same process of tilting and taking out the welding rods is repeated. Alternatively, a bunch can be taken out at a time and placed outside the cylinder. This can be used for a period of time, but after a long time, the welding rod cools down to room temperature and does not meet the usage requirements. After use, it will affect the quality of the weld. Utility Model Content

[0004] To facilitate the handling of welding electrodes, this application provides a pop-out welding electrode insulation cylinder.

[0005] The present application provides a pop-out welding rod insulation cylinder using the following technical solution:

[0006] A pop-out welding rod insulation cylinder includes: an inner cylinder, an outer cylinder, and a pop-out mechanism; the inner cylinder is slidably disposed in the inner cavity of the outer cylinder, and a cylinder cover is provided on the top of the outer cylinder, one end of the cylinder cover being hinged to the top of the outer cylinder;

[0007] The pop-out structure is disposed on the outer side wall of the outer cylinder, and one end of the pop-out mechanism is fixedly connected to the cylinder cover, and the other end passes through the side wall of the outer cylinder and is fixedly connected to the bottom of the inner cylinder; the pop-out mechanism is used to realize that the inner cylinder pops out of the inner cavity of the outer cylinder simultaneously when the cylinder cover is opened;

[0008] The inner cylinder is used to hold welding rods.

[0009] By adopting the above technical solution, the welding rod insulation cylinder is set up so that after the welding rod is dried, the welding rod is placed in the inner cylinder. The cylinder cover seals the inner cylinder inside the outer cylinder cavity to keep the welding rod warm. When the welding rod needs to be taken out, the pop-out mechanism is adjusted. The pop-out mechanism opens the cylinder cover and pops the inner cylinder out from the outer cylinder cavity, exposing the welding rod in the inner cylinder. The operator can then take out the welding rod that needs to be used, avoiding the inconvenience of the operator taking out the welding rod due to the narrow space of the inner cylinder.

[0010] In one specific implementation, the pop-out mechanism includes a cover switch assembly and a lifting assembly. The cover switch assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is fixedly connected to the cover, and the other end is hinged to the end of the second connecting rod. The second connecting rod is vertically arranged, and the end of the second connecting rod away from the first connecting rod is hinged to the lifting assembly. The lifting assembly passes through the outer cylinder sidewall and is fixedly connected to the inner cylinder.

[0011] By adopting the above technical solution, the cylinder cover opening and closing assembly applies force to the lifting assembly when the welding rod needs to be retrieved. The lifting assembly drives the second connecting rod to descend, the second connecting rod drives the first connecting rod to rotate, and the first connecting rod drives the cylinder cover to rotate at the hinge position with the outer cylinder, thereby opening the cylinder cover and facilitating the operator to retrieve the welding rod. After retrieval, the force applied to the lifting assembly is released, and the cylinder cover automatically closes and descends under the action of gravity, driving the first connecting rod to rotate. The first connecting rod drives the second connecting rod to rise, and the cylinder cover seals the outer cylinder, thereby achieving the sealing and heat preservation of the welding rod in the inner cylinder.

[0012] In one specific implementation, the lifting assembly includes a lifting link, a support base, a third link, and a lifting slider; the lifting link includes an integrally formed horizontal section and an inclined section, the horizontal section and the inclined section forming a certain angle, one end of the inclined section extending into the inner cavity of the outer cylinder, and the connection between the horizontal section and the inclined section being hinged to the end of the second link away from the first link; the support base is fixedly disposed at the bottom of the inner cavity of the outer cylinder, and the support base is hinged to the middle section of the inclined section, and the end of the inclined section away from the horizontal section is hinged to the end of the third link;

[0013] The end of the third connecting rod away from the inclined section is fixedly connected to the lifting slider, which is fixedly disposed at the bottom of the inner cylinder and located on the side of the inner cylinder away from the second connecting rod.

[0014] By adopting the above technical solution, the lifting assembly, when the cylinder cover is opened, presses the horizontal section, which drives the inclined section to rotate around the support base. At the same time, the end of the inclined section away from the horizontal section tilts up, which drives the third connecting rod to rise. The third connecting rod drives the lifting slider to rise, and the lifting slider lifts the inner cylinder. Thus, the inner cylinder pops out from the inner cavity of the outer cylinder at the same time as the cylinder cover is opened, making it convenient for operators to take the welding rod.

[0015] In one specific implementation, the bottom of the inner cylinder is set as an inclined surface, and the inner cavity depth of the inner cylinder gradually increases from the side away from the lifting slider to the side closer to the lifting slider.

[0016] By adopting the above technical solution, the bottom of the inner cylinder is set as an inclined surface, so that the welding rods stored in the inner cylinder are affected by gravity and gather at the lowest point of the inner cylinder, which helps to avoid the welding rods being stored haphazardly in the inner cylinder and improves the neatness of the welding rod storage.

[0017] In one specific implementation, a footboard is fixedly provided at the end of the horizontal section away from the inclined section.

[0018] By adopting the above technical solution, the pedal is designed so that when the operator takes the welding rod, stepping on the pedal facilitates the adjustment of the ejection mechanism, causing the inner cylinder to eject as the cylinder cover opens, thus providing convenience for the operator to take it.

[0019] In one specific implementation scheme, a heating unit is further included, which is fixedly disposed between the outer cylinder and the inner cylinder, and the heating unit is fixedly connected to the inner sidewall of the outer cylinder.

[0020] By adopting the above technical solution, the heating unit is set up so that when the welding rod is stored in the inner cylinder, the heating unit heats the welding rod to keep it warm, which facilitates the extension of the heat preservation time of the welding rod and thus improves the heat preservation effect of the welding rod.

[0021] In one specific implementation, the lifting link, support base, third link, and lifting slider are made of high-temperature resistant material.

[0022] By adopting the above technical solution, the lifting connecting rod, support base, third connecting rod, and lifting slider are made of high-temperature resistant materials, which helps to avoid damage to the lifting connecting rod, support base, third connecting rod, and lifting slider caused by the high temperature of the heating unit during operation, thereby improving the service life of the insulation cylinder.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The welding rod insulation cylinder is designed so that after the welding rods are dried, they are placed into the inner cylinder, and the cylinder cover seals the inner cylinder within the outer cylinder cavity. The heating unit heats the welding rods. When the welding rods need to be removed, the ejection mechanism is adjusted, which opens the cylinder cover and ejects the inner cylinder from the outer cylinder cavity, exposing the welding rods inside. The operator can then remove the welding rods that need to be used. This design avoids the inconvenience caused by the narrow space inside the inner cylinder and also prevents the heating unit from burning the operator's hands, thus improving the safety of handling welding rods.

The second connecting rod 312 is vertically arranged, and the end of the second connecting rod 312 away from the first connecting rod 311 is hinged to the lifting assembly 32. The lifting assembly 32 passes through the side wall of the outer cylinder 2 and is fixedly connected to the inner cylinder 1. The lifting assembly 32 includes a lifting connecting rod 321, a support base 322, a third connecting rod 323, and a lifting slider 324. All components—the lifting connecting rod 321, support base 322, third connecting rod 323, and lifting slider 324—are made of high-temperature resistant materials to prevent damage to the lifting assembly 32 from the heating unit 4, thus affecting the service life of the insulation cylinder. The lifting connecting rod 321 includes an integrally formed horizontal section 3211 and an inclined section 3212. The horizontal section 3211 and the inclined section 3212 form a certain angle. The inclined section 3212 extends downwards, with one end extending into the inner cavity of the outer cylinder 2. The connection point between the horizontal section 3211 and the inclined section 3212 is away from the first connecting rod 311 and the second connecting rod 312.

[0034] The implementation principle of the pop-out welding rod heat preservation cylinder of this application is as follows: After the welding rod is dried, it is placed in the inner cylinder 1.

Simultaneously, the lifting connecting rod 321, at the end away from the second connecting rod 312, rises around the support base 322, driving the third connecting rod 323 to rise. The third connecting rod 323 drives the lifting slider 324 to rise, lifting the inner cylinder 1 and causing it to pop out of the inner cavity of the outer cylinder 2. The welding rod in the inner cylinder 1 is exposed, and the worker picks up the welding rod to perform welding operations. After the welding is completed, the pressure on the pedal 33 is stopped, and the inner cylinder 1 descends under the action of gravity, causing the end of the lifting connecting rod 321 away from the second connecting rod 312 to rotate downwards. The lifting connecting rod 321 drives the second connecting rod 312 to rise, and the second connecting rod 312 drives the first connecting rod 311 to rotate. The cylinder cover 21 also closes automatically under the action of gravity, keeping the remaining welding rod warm.
