Abstract
A novel rock electric drill used in mine comprises an electric motor, a reduction box and a runway; the output end of an electric shaft (1) of the drill electric motor and the right end of a main shaft (8) are directly made to be gear shafts and separately meshed with a gear (2) and a gear (7); the middle part of the main shaft (8) is equipped with two bearings (9) to support the main shaft (8); the main shaft (8) and a drill stem (12) are fixed by a U-shaped bolt (14). The drill can be used freely in mining or drilling operations, which can not only promote the working efficiency but also save material. The drill can be widely used in digging mine roadway, building road, water conservancy, metallurgy, mining and rock excavation; the drill can also be used for drilling injection holes, water probing holes and gas probing and discharging holes in coal bed.
Description
Technical field:
The utility model relates to mining rock drilling shot hole instrument, a kind of new type mining electric rock drill.
Prior art:
The electric rock drill that mining is at present used is a kind ofly to be power with motor, by reducer, propulsive mechanism, and the rotary cutting rig of realization bore operation, it mainly is made up of motor, reduction box and runway etc.Motor and reduction box fuse and are called main frame, on runway, carry out work by sprocket wheel, chain, thereby engineerings such as mine laneway driving, metallurgical mining are carried out operation, brought into play great role, but also there is certain problem, for example use this electric drill when bore operation, be easy to damage drill bit and part, perhaps skid and bore not go down because rig strength is not enough if run into hard rock; Because the crash shock power of rig and rock is bigger during boring, very easily damage the bearing of supporting spindle; Simultaneously, the main shaft of rig and drilling rod can only just change for being threaded, and can not reverse, otherwise main shaft will throw off with being connected of drilling rod, bring bigger trouble for withdrawing from of rig.
Summary of the invention:
In order to overcome above-mentioned defective, the utility model provides a kind of new type mining electric rock drill, and utilization has not only improved operating efficiency freely when making the mining bore operation, has also saved material.
The utility model is to adopt following technical scheme to solve the problem of above-mentioned existence:
A kind of new type mining electric rock drill, form by motor, reduction box and runway etc., directly make gear shaft on the electric drive axle output of the motor of this rig, by this gear shaft meshing gear, gear and worm shaft connect firmly, gear shaft and worm shaft connect firmly, gear shaft meshing gear, the gear shaft engagement that directly make the internal tooth of gear and main shaft right part; Two bearing supporting spindles are arranged at the middle part of main shaft; The left part of main shaft has one section to be six square shafts, is provided with cannelure on this six square shaft; Also be provided with the six square shaft covers that match therewith on the drilling rod termination that is connected with main shaft with two radial holes; U type latch is inserted in this radial hole, just drilling rod can be fixed on the main shaft.
There is one section external screw thread termination at the main shaft of this rig, can connect the drilling rod that head is an internal thread.
Owing to adopted technique scheme, the utlity model has following superiority:
Motor shaft output of the present utility model connects direct geared by original key and changes gear shaft into, gear shaft is made in the end of main shaft, gear is connected with the key of main shaft and changes gear spline into and connect, and main shaft and motor reel have all increased the diameter of axle, have improved the intensity of main shaft and motor reel.Diameter of axle place at supporting spindle changes two bearings into by an original bearing, has increased supporting capacity, and bearing is no longer often damaged.Being connected to be changed into by original being threaded of main shaft and drilling rod existingly is threaded and has six square shafts to connect, and makes drilling rod and rig possess two kinds of connected modes.When adopting six square shafts to connect, rig can be realized rotating and reverse, and is unlikely to the disengagement that is connected of drilling rod and main shaft, has made things convenient for use.This rig and drilling cramp are used, but level forward, be tilted to, be tilted to down boring; Adopt wet boring water row powder, can improve working conditions and prolong drilling life of bit; When operation, only need hand wheel, main frame can move forward and backward automatically.This rig can be widely used in the mine laneway driving, road performance, and water conservancy construction, the operation of metallurgical mining and stonework also can be bored water injection hole in the coal seam, visit the water hole and visit the methane hole.
The drawing explanation:
Fig. 1 is a new type mining electric rock drill structural representation;
Fig. 2 is a new type mining electric rock drill U type latch structure schematic diagram.
As shown in FIG.: the 1-motor shaft, the 2-gear, the 3-gear shaft, the 4-worm shaft, the 5-gear, the 6-worm shaft, the 7-gear, the 8-main shaft, the 9-bearing, 10-six square shafts, 11-(on six square shafts) cannelure, 12-drilling rod, 13-handwheel, 14-U type latch.
Specific embodiment:
As shown in fig. 1, this mining electric rock drill is by motor, composition such as reduction box and runway, on electric drive axle (1) output of motor, directly make gear shaft, by this gear shaft meshing gear (2), gear (2) connects firmly with worm shaft (4), driven gear when motor rotates (2) rotation, driving gear shaft (3) same and that worm shaft (4) connects firmly by gear (2) again rotates, make gear shaft (3) meshing gear (7) rotation, the internal tooth of gear (7) drives the gear shaft rotation of directly making main shaft (8) right part, make main shaft (8) rotation, thereby drive drilling rod (12) rotation carrying out operation.At the middle part of main shaft (8) is to strengthen support force, supports main shaft (8) by two bearings (9).The left part of main shaft (8) has one section to be six square shafts (10), on this six square shaft, be provided with cannelure (11), match with the six square shaft covers of making on drilling rod (12) termination with two radial holes, U type latch (14) is inserted in this radial hole, just drilling rod (12) can be fixed on the main shaft (8), drilling rod (12) is the time spent not, and U type latch (14) is extracted out, both drilling rod (12) can be taken off easily; Still keep one section external screw thread in the termination of main shaft (8), can connect the drilling rod that head is an internal thread.When operation, only need hand wheel (13), main frame can move forward and backward automatically.
Claims (2)
1, a kind of new type mining electric rock drill, form by motor, reduction box and runway etc., it is characterized in that: directly make gear shaft on the electric drive axle of the motor of this rig (1) output, by this gear shaft meshing gear (2), gear (2) connects firmly with worm shaft (4), gear shaft (3) connects firmly with worm shaft (4), gear shaft (3) meshing gear (7), the gear shaft engagement that directly make the internal tooth of gear (7) and main shaft (8) right part; At the middle part of main shaft (8) two bearings (9) supporting spindles (8) are arranged; The left part of main shaft (8) has one section to be six square shafts (10), is provided with cannelure (11) on this six square shaft; Also be provided with the six square shaft covers that match therewith on drilling rod (12) termination that is connected with main shaft (8) with two radial holes; U type latch (14) is inserted in this radial hole, just drilling rod (12) can be fixed on the main shaft (8).
