Description

TECHNICAL FIELD

[0002] In the field of heating ventilation air conditioning, the test of the thermal performance of the radiation plate is a key link to ensure product quality and performance. According to the current industry standard JG / T 403-2013 "Radiation Cooling and Heating Device Thermal Performance Test Method", when the thermal performance of the radiation plate is tested, if the top installation method is used for the test sample, the test sample needs to be hoisted on the top of the test chamber, and a certain distance (0.2 m to 0.3 m) is kept to ensure the accuracy of the test.

[0003] At present, the technical scheme for realizing this hoisting process mainly depends on the traditional hoisting method. Specifically, the top of the test chamber is fixed with a lifting frame, a lifting ring is installed on the lifting frame, and a lifting ring is also installed on the surface of the radiation plate sample to be tested. By manual lifting, the lifting ring on the surface of the sample is connected to the lifting ring on the lifting frame by a rope, thereby completing the entire hoisting process. However, this existing technology has significant defects. First of all, it completely relies on manual hoisting, which is a primitive method and does not reflect the concept of intelligent production, nor can it effectively liberate labor. Especially when dealing with heavy samples such as metal radiation plates and gypsum radiation plates, due to the limitation of manual hoisting strength, at least four workers are needed to cooperate to complete the hoisting, which undoubtedly greatly reduces the installation efficiency and increases unnecessary labor costs. In addition, this hoisting method that relies on a large number of manpower is not conducive to the rational allocation of human resources and the improvement of test work, and also hinders the promotion and application of mechanized and automated production in the field of radiation plate testing.
