Description

TECHNICAL FIELD

[0001] The utility model is suitable for fire -retardant coating spraying technical field, especially in kind of coal mine underground fire -retardant coating spraying device. BACKGROUND

[0002] At present, as an important means of preventing and treating coal spontaneous combustion, roadway spraying can reduce air leakage in the roadway, prevent broken floating coal in the roof fall area and goaf from spontaneous combustion due to low temperature oxidation.

[0003] However, when using the spraying mechanism to spray fireproof material on the inner wall of the coal mine underground roadway, the operator usually holds the corresponding rod body to attach the spraying pipe close to the inner wall of the roadway for spraying processing. In this process, the operator needs to manually hold the spraying pipe to move along the semicircular roadway. This operation method cannot ensure that the spraying pipe always moves at a uniform speed, which easily leads to uneven spraying of the fireproof coating, affects the fireproof quality, and increases the labor consumption of the operator, affecting the overall fireproof spraying efficiency of the roadway. Therefore, we propose a coal mine underground fireproof coating spraying device. UTILITY MODEL CONTENT

[0009] As an optional solution of the technical scheme of the application, the connecting mechanism comprises a fixed sleeve and a transmission sleeve, both sides of the top of the fixed base are fixedly provided with fixed plates, rotating rods are rotatably installed between the side edges of the two groups of fixed plates through bearings, the middle end surface of the rotating rod is fixedly sleeved with a fixed sleeve, the bottom surfaces of both sides of the sliding frame are fixedly provided with connecting plates, a mounting rod is rotatably installed between the side edges of the two groups of connecting plates through bearings, the middle end surface of the mounting rod is fixedly sleeved with a transmission sleeve, a servo motor is fixedly installed on the outer side surface of the fixed plate, and the side edge of the transmission shaft of the servo motor is fixedly connected with the outer side of the rotating rod through a shaft coupling, and a guide sliding groove is formed in the inner part of the guide frame, and the sliding frame is slidingly inserted into the inner part of the guide sliding groove.

[0010] By adopting the above technical scheme, under the rotating transmission of the rotating rod and the mounting rod, the two ends of the transmission rod can rotate relatively between the outer sides of the fixed base and the sliding frame when the transmission rod is subjected to transmission conversion processing, thereby ensuring the transmission conversion effect of the transmission rod.

[0014] By adopting the above technical scheme, under the communication of the material collecting pipe and the material conveying hose, after the fireproof paint is conveyed, the paint can still be discharged and conveyed to the inner wall of the tunnel for spraying of the fireproof coating after the spraying position of the paint is adjusted with the rotation of the material collecting pipe.
