Description

Technical Field

[0001] This utility model relates to the field of steel truss welding technology, specifically a steel truss welding protective device. Background Technology

[0002] Steel trusses are trusses made of steel. They are commonly used as the main load-bearing components in the roof structures of industrial and civil buildings, crane beams, bridges, and hydraulic gates. When welding, protective equipment is required to prevent workers from being harmed during welding. With the continuous development of steel truss welding, various protective devices have emerged, such as a steel truss welding protective device.

[0003] A search revealed a welding protective tool in Chinese utility model patent CN215273834U. The mask body includes an air purifier mounting plate and protective goggles, with the bottom of the mask body connected to a handle. The handle has a thumb buckle on one side and index, middle, and ring finger buckles on the other side. The bottom of the handle is connected to a collar via a connecting rope. The index, middle, ring, and thumb buckles use the same structure to connect to the handle. The buckle body of each buckle has a threaded section at its end, and the mounting point on the handle has a finger buckle groove with a threaded hole within it. The buckle body connects to the handle... The handles are movably connected to the threaded holes via threaded sections; the sleeve includes several connecting blocks; the connecting blocks are connected by two connecting ribs. This utility model effectively prevents the face mask from slipping or falling from the operator's hand during use. Although this protective tool can effectively prevent the face mask from slipping from the operator's hand during use, the operator still needs to hold the handle tightly during use, continuously bearing the weight of the protective face mask, which leads to hand fatigue and is not conducive to long-term use. Therefore, a steel truss welding protective device is proposed that can suspend the protective face mask and hang it around the operator's neck with an elastic band, saving arm strength and facilitating comfortable welding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel truss welding protective device that can suspend the protective mask and hang it around the operator's neck with an elastic band, saving arm strength and facilitating comfortable welding. It solves the problem in Chinese utility model patent CN215273834U that during use, the operator still needs to hold the handle tightly and continuously bear the weight of the protective mask, resulting in hand fatigue and making it unsuitable for long-term use.

[0005] To achieve the above-mentioned purpose of being able to lift the protective mask and hang it around the operator's neck with an elastic band, saving arm strength and facilitating comfortable welding, this utility model provides the following technical solution: a steel truss welding protective device, including a support frame, a base plate fixedly installed at the bottom of the support frame, and an adjustment mechanism provided on the outside of the support frame;

[0006] The adjustment mechanism includes a mounting box, a micro motor, a cable, a first pulley, a second pulley, a connecting ring, a protective face shield, an elastic band body, and a controller. The mounting box is fixedly installed on the outside of the support frame, and the micro motor is fixedly installed inside the mounting box. The output end of the micro motor is fixedly connected to the cable. The top of the support frame is provided with a first pulley and a second pulley. The end of the cable away from the micro motor is fixedly connected to a connecting ring. The bottom of the connecting ring is fixedly connected to a protective face shield. The outer side of the protective face shield is provided with an elastic band body, and the controller is fixedly installed on the outside of the support frame.

[0007] Furthermore, a welding goggle is provided on the right side of the protective mask, and a cotton strip is provided on the outside of the protective mask.

[0008] Furthermore, a protective net is provided on the right side of the protective mask, and a ventilation opening adapted to the protective net is provided on the outside of the protective mask.

[0009] Furthermore, two locking posts are fixedly installed inside the protective face shield, and filter masks are provided on the outside of the two locking posts.

[0010] Furthermore, the bottom of the base plate is provided with three brakeable omnidirectional wheels, which are evenly distributed on the bottom of the base plate.

[0011] Furthermore, the controller is equipped with a battery, and the controller is electrically connected to the micro motor via wires, with the micro motor powered by the battery.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This steel truss welding protective device, through an adjustment mechanism, allows the support frame to be pushed near the steel truss via brakeable casters when welding is required. The device then brakes, and a micro-motor is activated by a controller to gradually wind out the appropriate length of cable, causing the protective mask to slowly descend to the desired position. The worker then puts the elastic band of the outer part of the protective mask around their neck, securing it with the cable to reduce the impact of the mask's weight. During welding, sparks are sprayed onto the protective net, and fumes are filtered through the mask before being inhaled. The adjustment mechanism can also suspend the protective mask and use the elastic band to hang it around the operator's neck, saving arm strength and facilitating comfortable welding.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) When welding the steel truss is required, push the support frame 1 to the vicinity of the steel truss using the brakeable caster 7 and then brake it;

[0030] 2) Then, the micro motor 302 is started by the controller 309, so that the cable 303 is gradually wound out to an appropriate length, and the protective mask 307 slowly falls to the appropriate position;

[0031] 3) Then put the elastic band body 308 of the protective mask 307 on the back of your neck and hang the protective mask 307 with the cable 303 to reduce the impact of the weight of the protective mask 307.

[0032] 4) During the final welding process, sparks are sprayed onto the protective net 5, and the fumes are filtered through the filter mask 601 before being inhaled.

[0033] In summary, this steel truss welding protective device, through the setting of the adjustment mechanism 3, when the steel truss needs to be welded, pushes the support frame 1 to the vicinity of the steel truss via the brakeable universal wheels 7 and then brakes it. The micro motor 302 is started by the controller 309, so that the cable 303 gradually winds out an appropriate length, and the protective mask 307 slowly falls to the appropriate position. The worker then puts the elastic band body 308 of the protective mask 307 behind his neck and hangs the protective mask 307 with the cable 303 to reduce the impact of the weight of the protective mask 307. During welding, the sparks are sprayed onto the protective net 5, and the fumes are filtered by the filter mask 601 before being inhaled. The adjustment mechanism 3 can also lift the protective mask 307 and hang it around the operator's neck with the elastic band, saving arm strength and facilitating comfortable welding.
