Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting apparatus strength testing, in particular to a fire-fighting apparatus strength testing platform. Background Art

[0002] Firefighting equipment usually refers to firefighting tools, equipment used for fire extinguishing, fire prevention and fire accidents. It is equipment used for professional firefighting. The quality of firefighting equipment is crucial to fire safety. If there are problems with the quality of firefighting equipment, it will not only fail to extinguish the fire effectively, but may also cause secondary disasters due to problems such as leakage and rupture. Therefore, in order to ensure the quality of firefighting equipment, the firefighting equipment must be strength tested after production is completed. In the prior art, when testing firefighting equipment, it is first necessary to install the firefighting equipment on a test bench. After the installation is completed, a high-pressure water flow is injected into the firefighting equipment to observe whether the firefighting equipment is effective through the continuous increase in water pressure. Deformation can be generated to determine whether the strength of the fire-fighting equipment meets the standard, which is convenient for determining the production quality of the fire-fighting equipment. During the test, when the strength of the fire-fighting equipment does not meet the standard, the fire-fighting equipment is prone to damage and high-pressure water will spray out. In order to ensure the safety of the fire-fighting equipment strength test, protective components will be installed at the opening at the front end of the fire-fighting equipment strength test bench to prevent the outward discharge of high-pressure water. However, in order to ensure the normal installation of the fire-fighting equipment, some test benches use hinges to open and close the protective components and connect them to the test bench. When the sprayed water pressure is large, the protective components may be easily disengaged from the limit under the impact of the water flow, resulting in reduced protection effect.
