Embodiment
[0014] An embodiment of the present invention provides a convenient suspension device for a coal mining downhole air duct, which will be described in detail below.
[0015] Refer to attached figure 1 , 2 A hook 1 in a convenient hanging device for an underground air duct in a coal mine is composed of a fixed hook 1-1, a sealing hook piece 1-2, a spring 1-3 and a fixed pin 1-4, and the spring 1-3 is located on the fixed hook 1 -1 and the middle part of the sealing hook piece 1-2 are respectively connected to the two; wherein the fixed hook 1-1 and the sealing hook piece 1-2 are connected and fixed through the fixed pin 1-4 of the overlapped part below the two; the bottom of the hook 1 It is welded together with the fixed frame 2 to play a stabilizing role, and is used to prevent the air duct from slipping; at the same time, a support plate 3 is welded on the inner surface of the fixed frame 2, and the air duct lead wire is fixed together with the connecting rod 5 and the extru...

The invention provides a convenient hanging device for an underground air duct in coal mining. The convenient hanging device is mainly composed of a hook, a fixed frame, a supporting plate, an extrusion sheet, a rotating sleeve and a connecting rod. According to the device, the extrusion sheet with latticed lines and the supporting plate engraved with S-shaped wire grooves are used for fixing an air duct lead, meanwhile, a safety hole is used for fixing the air duct lead for the second time, and then the hook is directly hung on a T-shaped beam of a trapezoidal roadway, so that the head raising working time of personnel is shortened, and the working intensity of the personnel is reduced. After roadway construction is completed, the hook can be directly taken down, and the lead is recycledto prevent people from being hurt or prevent an air duct from being damaged. Therefore, the device has the characteristics of being simple in structure, low in investment cost, convenient to operate,low in labor intensity, capable of being used repeatedly and high in practicability.
Description
technical field [0001] The invention relates to the field of mine equipment, in particular to a convenient suspension device for an underground air duct for coal mining. Background technique [0002] At present, in the process of coal mining and excavation, in order to ensure normal ventilation, the air duct is often hung on the roof through the lead wire, and then ventilated through a local fan; On the beam, it is not conducive to recycling, the safety is low, and it is easy to accidentally injure people or the blower; at the same time, when the construction personnel install the lead wire of the blower, they need to work with their heads up for a long time, the labor intensity is high, the safety is low, and the fixing effect is low. poor. Contents of the invention [0003] The purpose of the invention is to solve the problems of unstable fixing of the lead wire of the air duct, low efficiency, complicated binding, difficult recovery, poor safety and high labor intensit...
