Abstract
The utility model relates to a drilling machine for a gallery, belonging to a mining machine, which can be used for the drilling of underground tunnels and above works. The utility model is one drilling machine with water pressure drilling and a mechanical power head and uses water to replace oil for automatically regulating the drilling speed and pressure. The utility model has the characteristics of short machine frame, effective path length feeding, simple rod dismantling system, and motorized pipe screwing. The volume and weight of the drilling machine for the gallery is the one half of a full liquid type drilling machine and the dynamic force can be saved one third.
Description
The utility model relates to a kind of underground drill rig, belongs to mining machinery, is used for the boring of tunnel and ground surface works.
With the MyZ-150 type gas drainage under suction underground drill rig of imitative Britain as prior art.This rig is that oil pressure feeds, the power head type drill rig of oil pressure main transmission, third gear speed change, in use has the following disadvantages:
1, total transmission efficiency less than 50 percent, energy waste is big.The high power hydraulic element costs an arm and a leg, and makes the cost of use height, and maintenance operation requires high, and the fluid of use requires high, in down-hole or the field work, uses difficulty many, and the rate of starting is low, and the range of speeds is little, the bad adaptability that different rock-layers is crept into.
2, rate of penetration and pressure do not have automatic regulatory function, want manual observation the pressure of the drill to change during operation, regulate rate of penetration;
3, adopt the direct driving structure of oil cylinder, thereby frame is long, effectively feeds the stroke weak point.It is wide that China tunnel is generally 2.2m, and need specialize in the cavern and put rig, thereby long in time limit, expense is big.
4, adopt the counter-rotating high pulling torque to twist linkage and unload bar, complicated and the screw thread that can only motor-driven unloading drilling rod one end of mechanism, other end screw thread must be used artificial unloading.
The purpose of this utility model just is to overcome the weak point in the above-mentioned prior art, provide that a kind of hydraulic pressure feeds, the power unit type underground drill rig of mechanical main transmission, fourth gear speed change, its with water for oil, can regulate rate of penetration and pressure automatically, the machinery driving efficiency height, it is low to make cost of use, and operating maintenance is easy, and it is short to have frame, effectively feed stroke long, unload linkage simple, unload the whole vehicularized characteristics of bar.
The utility model is achieved in that does antirust Wear-resistant Treatment with Hydraulic Elements, replaces hydraulic oil with emulsion or clear water; Adopt reducing valve decomposition pressure automatic adjustment circuit to realize the automatic adjusting of rate of penetration and pressure; Adopt assembly pulley line increment range device to make the frame contraction in length, effectively feed stroke and increase, adopt without screw thread formula water just with the one modularization structure of through hole unit head axle, simplified and unloaded the bar operation.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Fig. 1 is an overall construction drawing of the present utility model;
Fig. 2 is that feeding rate of the present utility model, pressure are regulated hydraulic circuit diagram automatically;
Fig. 3 is an assembly pulley line increment range device structure chart of the present utility model;
Fig. 4 be without screw thread formula water of the present utility model just with the one modularization structure chart of through hole unit head axle.
The utility model is made up of mechanical main transmission, hydraulic system, assembly pulley line increment range device and unit head.In the transmission system, the power of prime mover (8) through chain (9), gearbox (10), sprocket wheel bevel gear pair (1), power transmission shaft (2), pass on the unit head (5), make its rotation, unit head (5) go up to be installed rod bit.The promotion of rod bit is finished by hydraulic system and assembly pulley line increment range device, at first the power of prime mover (8) drives pump (6) through gearbox (7), the liquid of pump (6) drives cylinder (3) and moves through reducing valve (12), reversal valve (11), and cylinder (3) drives unit head (5) through assembly pulley line increment range device and moves.Hydraulic Elements wherein can use 2% emulsion or clear water replacement hydraulic oil through antirust processing such as hard chrome plating.Unit head comprises without screw thread formula water just (18) and through hole unit head axle (15), both are the one combining structure, without screw thread formula water just is hollow shaft structure, be installed in the inner core of through hole unit head axle (15) by spring (13) seal cover (14), sealing ring etc., its conical end is inserted in the drilling rod hole, by sealing ring (17) sealing, drilling rod is then tightened by drilling rod chuck (16).Flushing liquor enters into without screw thread formula water just (18) from water inlet (19), delivers to foot of hole by drilling rod, drill bit, thereby cools off drill bit and discharge the rock break flour.
Compared with the prior art, the utlity model has following advantage:
1. mechanical type main transmission efficient height, it is low to make usage charges, and operating maintenance is simple, and for oil, material source is convenient with water, and remarkable in economical benefits is pollution-free, at present domestic and international anhydrous pressure type rig still.
2. because having adopted pressure-reducing valve in the hydraulic system, during practical operation, when drill pressure changed, pressure-reducing valve is the water yield of regulation output automatically, finished thus automatic adjusting feeding rate, had simplified operating process, had improved rig efficient, had guaranteed construction safety.
3. adopted assembly pulley line increment range device, it is long that stroke is lacked, effectively fed to frame, need not special-purpose cavern and put rig, thereby greatly reduce engineering cost and time.
Because of adopted above-mentioned without screw thread formula water just with the integrated combining structure of through hole unit head axle, when having holed man-hour, only need water seal cover, spring and button water is just just taken away, just available through hole unit head is transferred to the drilling rod in the hole to come one by one, when transfering to a drilling rod, block the notch of drilling rod by the drilling rod chuck, the free jaw type clamping bar device of the other end of unit head is clamped drilling rod, is just changeing the every joint screw thread that can lay down drilling rod and start unit head.The water of domestic and international various rigs just all is connected with drilling rod with screw thread at present, and whenever adding a drilling rod must counter-rotating unloading screw thread.During drilling rod, motor-driven unloading screw thread can only be laid down the screw thread of drilling rod one end in the hole is transferred in boring completion back, the screw thread of the other end can only be manually with freely clamping unloading, so of the present utility model to unload linkage simple, and easy to operate, saving of work and time.
5, this machine compared with the prior art, a volume weight young waiter in a wineshop or an inn/one saves power 1/3rd, manufacturing cost saves 1/2nd, usage charges save 2/3rds.
