Description
Technical Field
[0001] The invention relates to the technical field of fence welding tooling, in particular to a portable parking lot fence welding tooling. Background Art
[0002] As an important facility to ensure the order and safety of vehicle parking, parking lot fences play a key role in urban traffic management and public safety. They not only need to withstand the collision impact that may be caused by the frequent entry and exit of vehicles, but also have to be exposed to complex environments such as wind, sun, rain and snow for a long time. Therefore, their welding quality directly affects their service life and protective performance. If there are defects such as cold welds and air holes in the welding points, the overall structural strength of the fence will be reduced, causing it to easily break and deform when subjected to external forces, and it will be unable to effectively block vehicles or illegal intrusions. Poor welding technology will also accelerate the oxidation and rust of the metal, shorten the service life of the fence, and increase maintenance costs. Therefore, ensuring the high quality of parking lot fence welding is an important prerequisite for maintaining parking lot order and ensuring vehicle safety.
[0003] In actual welding operations, traditional tooling has many limitations: 1. The lack of convenient mobile and fixed structures makes it difficult to quickly adapt to the needs of different parking spaces, limiting operational flexibility; 2. The smoke and dust generated during the welding process easily spreads in the environment. The existing dust extraction and filtration equipment has a simple structure and cannot effectively purify the air, seriously endangering the health of operators; 3. Traditional tooling cannot effectively control the welding temperature, which can easily cause metal deformation and affect welding accuracy.
[0004] Therefore, a portable parking lot fence welding tool is urgently needed to solve the above problems. Summary of the Invention

By combining the cooling and dust reduction atomization component with the dust extraction component, the mist water vapor can quickly absorb the dust particles in the air after mixing with the air, causing the dust particles to settle due to the increase in weight, thereby effectively suppressing the rise of smoke and dust. At the same time, the water vapor is blown through the air duct by the dust extraction component to cool down the air, and the welding point is quickly cooled by the atomizing nozzle, effectively controlling the temperature of the welding point, reducing the deformation of the metal caused by high temperature, and ensuring the accuracy and quality of welding. This solves the problem in the existing technology that traditional tooling cannot effectively control the welding temperature, which easily leads to metal deformation and affects the welding accuracy.

The multi-stage filtration structure prolongs the contact time between the airflow and the filter material, fully filters the smoke and dust, and makes the exhausted air meet the cleanliness standard; the pump 30 draws water from the water tank 14 through the water inlet hard pipe 31, and transports it to the atomizing nozzle 37 through the water outlet hose 33 to spray mist water vapor. The mist water vapor mixes with the air to absorb the dust particles and make them settle. At the same time, the air in the air collecting box 19 enters the water tank 14 through the connecting box 15, and is blown out through the air duct 32 for cooling.
