Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, specifically to a collision protection device for gas cylinders of electric welding machines. Background Technology

[0002] Commonly used welding technologies include electric arc welding, argon arc welding, CO2 shielded welding, oxygen-acetylene welding, laser welding, electroslag pressure welding, etc. Electric arc welding that uses gas as the arc medium to protect the arc and the welding zone is called gas shielded arc welding. Generally, each welding machine is equipped with a dedicated gas cylinder for individual gas supply.

[0003] Existing anti-collision protection devices for welding machine gas cylinders, when optimized, mostly focus on loading the gas cylinders for convenient transportation. For example, Chinese utility model patent application number CN201720910337.5 discloses "A Gas Cylinder Transport Trolley for Welding Construction." This device includes two parallel horizontal bars with handles at one end, a stop bar connecting the two horizontal bars away from the handles, two vertically arranged support legs fixedly connected to the two horizontal bars and close to the handles, and vertically arranged upper ends of the support legs. The invention comprises a limiting rod, a connecting rod connecting the lower parts of the two legs, two arc-shaped plates connecting the two crossbars and located between the stop bar and the legs, a connecting rod connecting the lower ends of the two arc-shaped plates, two vertically arranged uprights fixedly connected to the two crossbars and close to the stop bar, a longitudinal bar connecting the lower ends of the two uprights, two traveling devices respectively set at both ends of the longitudinal bars, and a diagonal brace connecting the legs and the arc-shaped plates close to the legs. The lower part of the arc-shaped plate close to the stop bar is fixedly connected to the longitudinal bar. This invention is reasonably designed, has low manufacturing cost, and is suitable for welding engineering construction in the engineering field.

[0004] While the aforementioned anti-collision protection devices for welding machine gas cylinders offer certain advantages in loading and facilitating their transportation, they still have some drawbacks. Welding machines are typically equipped with and operate in conjunction with gas cylinders. During welding operations, personnel need to move around frequently, which can cause the gas cylinders to shift position. Without a carrier to facilitate their movement, personnel would need to manually move them repeatedly. Since the welding machine is connected to the gas cylinder via a gas supply pipe, any shift in the cylinder's position can easily lead to shaking or tipping, causing changes in the gas inside and creating safety hazards.

[0029] Please see Figure 3-4 A collision protection device for a gas cylinder of an electric welding machine includes a tensioning structure 35 comprising a connecting ring a1, a tensioning block a2, a limiting channel a3, and a limiting rod a4. The rear end of the tensioning block a2 is hinged to the connecting ring a1. The limiting channel a3 and the tensioning block a2 are an integral structure. The limiting rod a4 slides through the limiting channel a3 and engages with the tensioning block a2. The collision protection structure 5 includes an outer plate 51, an electric telescopic rod 52, a guide frame 53, an anti-deviation plate 54, and a pressing structure 55. The electric telescopic rod 52 is installed inside the outer plate 51, and its front end is connected to the rear end of the pressing structure 55. The guide frame 53 is fixedly installed inside the outer plate 51. One end of the anti-deviation plate 54 is fixedly connected to the end of the pressing structure 55, and the other end of the anti-deviation plate 54 is slidably connected to the guide frame 53. The outer periphery of the connecting ring a1... The upper end of the limiting rod a4 is rigidly connected to the inner side of the worm gear 36 and is perpendicularly connected to the inner top surface of the seat block 32. There are fourteen tension blocks a2. The position of the limiting rod a4 remains unchanged, and the tension blocks a2 can be displaced as the connecting ring a1 rotates. With the limiting assistance of the limiting rod a4, the inner ring diameter composed of the fourteen tension blocks a2 can be changed, thereby flexibly changing the fastening force of the tensioning structure 35 at the bottom of the gas cylinder 1 and oxygen cylinder 2. The outer end of the outer plate 51 is rigidly connected to the front end of the support plate 4. The middle part of the outer plate 51 penetrates the gas cylinder 1 and oxygen cylinder 2 respectively and is interference-fitted.

There are two electric telescopic rods 52 and two pressure-sensitive structures 55, which are symmetrically arranged.

[0030] Please see Figure 5 A collision protection device for a gas cylinder of an electric welding machine includes a contact structure 55 comprising a protective block q1, an arc block q2, a positioning plate q3, an inclined rod q4, a moving block q5, a swing rod q6, and a spring q7. The rear side of the protective block q1 is pressed into the arc block q2 by the spring q7. One end of the arc block q2 is fixedly connected to one end of the swing rod q6. The swing rod q6 is hinged to the positioning plate q3. One end of the swing rod q6 is hinged to the inclined rod q4. The other end of the inclined rod q4 is hinged to the moving block q5. The rear side of the moving block q5 is fixedly connected to the front end of an electric telescopic rod 52. The positioning plate q3 is fixedly installed on the outer plate. Inside block 51, the movable block q5 can be displaced, causing the tilting rod q4 to change its tilt angle. This allows the tilting rod q4 to apply an external force to one end of the arc block q2, facilitating the angular rotation of the arc block q2 around the hinged position with the positioning plate q3. This allows for adjustment of the position and force of the arc block q2 pressing against the gas cylinder 1 and oxygen cylinder 2. The protective block q1 is made of a plastic elastomer material with excellent elasticity and anti-slip properties. It can deform flexibly under force, assisting the arc block q2 in surrounding the gas cylinder 1 and oxygen cylinder 2. This not only limits the movement of the gas cylinder 1 and oxygen cylinder 2 but also prevents them from being subjected to hard impacts.

[0031] In summary, the operator places the gas cylinder 1 and oxygen cylinder 2, which are equipped with the welding machine, into the base 3. A tightening structure 35 is installed, allowing the bottoms of the gas cylinder 1 and oxygen cylinder 2 to pass through the upper port 31 and be inserted into the inner side of the tightening structure 35. The operator then rotates the handle 37 according to the tightness of the fit between the bottom of the gas cylinder 1 and oxygen cylinder 2 and the base 3. This rotates the worm gear 34, causing the meshing worm wheel 36 on the side to rotate, which in turn rotates the connecting ring a1. The tightening blocks a2 change position as the connecting ring a1 rotates. With the sliding cooperation of the limiting rod a4 and the limiting channel a3, the inner ring diameter of the fourteen tightening blocks a2 can be varied, thus flexibly adjusting the tightening force at the bottom of the gas cylinder 1 and oxygen cylinder 2. This ensures that gas cylinders 1 and oxygen cylinder 2 of different specifications receive a stable bottom force after being placed on the base 3, allowing the base 3 to accommodate various types of gas cylinders 1 and oxygen cylinder 2. Gas cylinder 1 and oxygen cylinder 2 need to pass through the anti-collision structure 5 before they can be placed on the base 3. By setting up the contact pressure structure 55, personnel can adjust the position of the arc block q2 according to the outer diameter of the gas cylinder 1 and oxygen cylinder 2, activate the electric telescopic rod 52, and let its front end drive the moving block q5 forward, causing the tilting rod q4 to change its tilt angle and apply a lateral thrust to the swing rod q6, so that the arc block q2 can swing and change at the fulcrum. The four arc blocks q2 change their positions simultaneously, effectively changing the clamping force around the gas cylinder 1 and oxygen cylinder 2, avoiding the phenomenon of large-scale shaking of the gas cylinder 1 and oxygen cylinder 2. The elasticity and anti-slip properties of the protective block q1, as well as its elastic cooperation with the spring q7, ensure that the protective block q1 can always be pressed against the outer surface of the gas cylinder 1 and oxygen cylinder 2, providing a good anti-collision effect for the gas cylinder 1 and oxygen cylinder 2 and reducing the possibility of damage to the gas cylinder 1 and oxygen cylinder 2 from hard impacts.
