Embodiment Construction

[0031] Such as figure 1 , figure 2 As shown, the full-section rapid drilling rig of the present invention is composed of a traveling mechanism, a vehicle frame, a hydraulic system, and two sets of drilling devices; wherein the first set of drilling devices in the two sets of drilling devices is used to drill ordinary blast holes, the second set of drilling device is used to drill holes with a diameter of more than 100mm;

[0032] The walking mechanism is a commonly used crawler-type walking chassis 1 with a design width of 1.0-1.2 meters. It consists of two sets of completely independent crawler frames on the left and right, a traveling motor, a reducer, a drive sprocket, a crawler chain, and a crawler tensioning mechanism. Each set of track frame is fixed with the frame by a vertical key, and then fastened with the frame with high-strength bolts; the reducer is connected with the track frame with high-strength bolts; the travel motor is driven by the reducer and the drive s...

Abstract

The invention discloses a whole-section quick-drilling drill carriage specially used for parallel cut blasting of large empty holes in a roadway. The drill carriage is composed of a walking mechanism, a carriage frame, a hydraulic system, an electrical system and two drilling devices, wherein the first drilling device is used for drilling common blasting holes, and the second drilling device is used for drilling cut holes with the diameter of 100 mm or more. In the operating process of the drill carriage, a hydraulic motor drives a main chain wheel of a crawler-type walking chassis to rotate through a speed reducer; after a carriage body is stabilized, the first drilling device and the second drilling device are manipulated to select hole locations respectively; after the first drilling device and the second drilling device are located, the common blasting holes and the empty holes with the diameter of 100 mm or more can be drilled in rock simultaneously. The drill carriage is suitable for the roadway with the minimum section of 8 square meters and the maximum section of 23 square meters; by the adoption of a building block structural design, the drill carriage is convenient and fast to disassemble and assemble and convenient to transport; as a result, the drill carriage can be used when the length of the roadway under tunneling construction is seven meters or more, and accelerates tunneling mechanization and quick and efficient tunneling modernization.

Description

technical field [0001] The invention relates to a blasting drilling rig, in particular to a blasting drilling rig for coal mine roadway excavation. Background technique [0002] The drill and blast method is still the main method of coal mine roadway excavation construction for a long time. In coal mine roadway engineering, 8-23m 2 The medium and small cross-section roadways are mainly used. In excavation construction, medium and deep hole blasting of 2-3 meters is the main method, and the key to medium and deep hole blasting is the choice of cutting method. According to the research, the best cutting method for medium and deep hole blasting is straight hole cutting. When cutting straight holes, it is necessary to leave dense holes without charge to improve the blasting free surface. With the research progress of researchers on void effect and rock crushing mechanism, a new method of large void hole straight hole cutting blasting has appeared in recent years, which has be...
