Description

Technical Field

[0001] The utility model belongs to the technical field of heap spraying support, in particular to spraying equipment for concrete support construction in coal mines. Background Art

[0002] The heap spraying process is a new method suitable for the rapid and efficient construction of support structures in coal mines. The process is to transport the premixed mixture to the sprayed surface at high speed and high pressure through a long-distance, large-flow concrete sprayer. According to the designed support plan, the support structure is constructed by stacking layer by layer by controlling the movement trajectory of the nozzle. Heap spraying does not require prefabrication and installation of templates, and is directly formed by relying on the high adhesion and rapid coagulation and hardening characteristics of the heap spraying material.

[0003] During the construction of shotcrete support, a concrete sprayer is required. Some sprayers are equipped with a hose in the water inlet pipe, which is fixed to the surface of the stainless steel water pipe by a clamp. Since the sprayer vibrates violently during use, the hose clamp may become loose, which may cause slight leakage at the hose connection end. Since leakage at the hose end is not easy to detect, it causes waste of water resources. Therefore, a spraying equipment for underground concrete support construction in coal mines is needed, which can monitor leakage at the hose in real time and notify staff to perform maintenance through flashing lights to reduce waste of water resources.
