[0038] Compared with the prior art, the propulsion system and the operation platform of the drill carriage are transformed to adapt to the adjustment of the mining roadway and the mining process. Firstly, the drill frame platform of the drill carriage is shortened to adapt to the appropriate propulsion distance, the travel distance of the propulsion system is adjusted, the power system, the propulsion system and the drill frame are effectively combined, secondly, the corresponding propulsion pipeline is distributed, the function of the drilling control system is optimized, the propulsion head reversing and adjustment control system are implemented, and the prerequisite for reverse upward hole forming is realized, and thirdly, according to the adaptation of the operation space, the drill tool selection is combined, the manual operation is light, the safety risk is controllable, the technical difficulty is simple and the like, the rod changer centralizer 2 is additionally arranged at the appropriate position, that is, used for controlling the perpendicularity of hole forming, which is more conducive to realizing hole forming efficiency and meeting the demand of compensation space.

[0039] The device adopts the vertical excavation and cutting reverse propulsion technology, can flexibly adapt to various terrain conditions, and the advantages are more obvious especially in complex geological environment. Although the raise drilling machine has a wide operation range, it may be greatly limited under certain specific terrain or geological conditions.

[0040] The device realizes quick rod changing through the convenient rod changing platform, so that the construction efficiency is improved. Compared with the complicated process of continuously hoisting and dismounting of the raise drilling machine, the device can save a large amount of time and labor cost.

[0041] The device is especially suitable for upward drilling operation of underground mines, and the vertical excavation and cutting reverse propulsion technology can ensure the accuracy and stability of drilling. Although the raise drilling machine can also operate underground, it usually needs a large occupied area and high lifting capacity operation equipment, and the device is more flexible and convenient.

[0042] In some embodiments, referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , the propulsion motor 3 comprises a power head, and the center of the power head and the center of the centralizer 2 are coaxial.

[0043] First, disassemble the original drill carriage Am length, generally 3.8m-5.8m is more appropriate, drill platform and stroke oil cylinder, measure the required stroke distance, shorten the stroke length of the drill platform and stroke oil cylinder, and test the appropriate push stroke; At the same time, adjust the existing propeller, rotary controller, centralizer control center, optimize the stroke distance and power output of the propulsion system, realize the effective combination of power system, propulsion system and drill stand.

[0044] The center of the power head and the center of the centralizer 2 are coaxial, which ensures the coaxiality during drilling and reduces the drilling error caused by equipment deviation. The centralizer 2 can accurately align the target drilling position, and after coaxial with the power head, the drilling accuracy is further improved. The coaxial design makes the power head run more smoothly during drilling, reducing the drilling deviation and hole wall damage caused by vibration.

[0045] In some embodiments, referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , the propulsion motor 3 bottom section shape is H-shaped, and the edge of the mast is sleeved in the H-shaped recess.

[0050] In some embodiments, referring to Figure 2 , Figure 4 , Figure 6 and Figure 8 , in the forward working condition of the mast, one end of the mast adjusting oil cylinder 5 is connected to the mast close to the mast head 4.

[0051] The mast adjusting oil cylinder 5 is connected to the mast close to the head at the bottom of the mast, which can more effectively support the overall weight of the mast, especially when upward drilling in the underground mine, which can ensure that the mast remains stable when bearing a larger load, reduces the shaking caused by vibration during drilling, and thus improves the accuracy and efficiency of drilling.

[0052] In some embodiments, referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , in the reverse working condition of the mast, one end of the mast adjusting oil cylinder 5 is connected to the mast close to the mast tail 1.

[0053] The corresponding propulsion pipeline is distributed, the function of the drilling control system is optimized, the oil circuit system is reasonably arranged, the propulsion head reversing and the control system adjustment are coordinated, and the basic conditions for reverse upward hole forming are realized.

[0054] In some embodiments, the distance between the centralizer 2 and the mast tail 1 is in the range of 1.2m-3.2m.

[0055] According to the adaptation of the operation space, combined with the selection of the drilling tool or drill pipe, the operation mode is light, the safety risk is controllable, the technical difficulty is simple, and other factors, using the principle of two-force balance, at a suitable position, generally between 1.2m-3.2m, depending on the selected drill pipe adaptation, a rod changer or centralizer 2 is added for controlling the perpendicularity of the hole forming, realizing the hole forming efficiency, and meeting the demand of compensation space.

[0056] In some embodiments, referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , the centralizer 2 and the propulsion motor 3 are detachable.

[0057] The detachable design of the centering device and the pushing motor enables the device to be quickly adjusted according to specific operation requirements, improves the flexibility and adaptability of the operation, and compared with the traditional raise boring machine, the raise boring device can be more convenient in maintenance and maintenance, and reduces the cost of maintenance and replacement of parts.

[0058] In some embodiments, referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , the mast adjusting oil cylinder 5 is used to drive the mast to move in the mast extension direction in the sliding system limiter 6.

[0059] The mast adjusting oil cylinder 5 can accurately control the movement of the mast, so as to ensure the accurate position and direction of the drill bit, and the sliding system limiter 6 as an accurate positioning device further limits the movement range of the mast, and improves the drilling accuracy.
