It provides support and ensures.After reaching some position, it is total in mast can to adjust drill head 8 in operation at this time for drill head 8
At the position on 7, i.e. drill head 8 can slide back and forth on mast assembly 7, and the drilling rod 6 on drill head 8 can thus reached and closes
Suitable job position, make entire drilling machine do not have to too close to setting, drilling rod 6 can also carry out drilling operation, ensure that drilling machine with
The distance between work surface makes operational security be improved.
In the switching mechanism of the present invention, the both ends of the first support device 2 can stretch, in this way in operation, first
The top and bottom end of support device 2 can in service tunnel roof and ground tight contact between, rack 10 is effectively solid
It is scheduled in tunnel so that drill head 8 can keep stable at work.First support device 2 is again rotatable, then making
Before industry, after rotation to different location, angle, then keeps its both ends flexible, can also realize any position in rotating range, the
Contact can be effectively fixed in one support device, 2 both ends, and in this way in the case of different angle, drill head 8 can also stablize operation.
In the present invention, there is revolution pedestal 20 between the first support device 2, this is one and is followed by the first support device 2 together
Mast assembly 7 is mounted on revolution pedestal 20, then mast assembly 7 will be with the first support device 2 by the structure for walking rotation
It rotates and rotates.And it itself is rotary to turn round pedestal 20, then the first support device 2 provides a certain range of rotation
Gyration, revolution pedestal 20 can provide a certain range of rotation angle again, and the two combines, and realizes mast assembly 7 in big model
Interior rotation is enclosed, such punch position can be adjusted significantly.
In addition, the mine lamp 12 in rack 10 is pointed into work surface when in use, to provide the bright visual field to operating personnel, and
Dust excluding plate 11 then plays the dust-proof and protective effect to mine lamp 12.
As shown in Fig. 3, Fig. 5, Fig. 6, it is both provided with pivoted frame 21 in the first support device 2, is set between this pair of of pivoted frame 21
It is equipped with adjustment axis 18；The revolution pedestal 20 includes a fixing frame plate, and the side of fixing frame plate is provided with through-hole
Erecting bed 19, erecting bed 19 are assemblied in by through-hole in adjustment axis 18, and pass through the side opening on erecting bed 19 to insert by fixed pin
Enter into adjustment axis 18 the relative position of platform 19 and adjustment axis 18 is fixedly mounted, then when installation, can also pass through
The different jacks being distributed in adjustment axis 18, initial angle when adjustment fixing plate frame is installed, to make revolution pedestal 20 have
The slewing area of bigger；Mounting hole is distributed on fixing frame plate, for being attached with drill head 8.
As a kind of above-mentioned 21 structure of pivoted frame, as shown in figure 3, pivoted frame 21 includes fastening block 23, in the side of fastening block 23
It is machined with arc groove on face, mounting hole is distributed on fastening block 23；Fastening block 23 is respectively provided in each first support device 2
First support device 2 is clipped in wherein per a pair of fastening block 23, is then fixed by bolt by a pair；At two first
Axle sleeve is both provided on the fastening block 23 of 2 the same side of support arrangement, the end of the adjustment axis 18 is assemblied in axle sleeve；Setting is tight
Gu 23 this fixed structure of block, benefit is easy for position of the installation and adjustment pivoted frame 21 in the first support device 2, while can protect
Hold the close connection between the first support device 2.
As shown in figure 3, for the structural schematic diagram of rack 10 in the present invention.Rack 10 includes a pair of spaced frame plate
26, the thick middle of frame plate 26, both ends are relatively thin；It is connected by loading plate 28 between frame plate 26；It is equal in the front end of each frame plate 26
There are pivoting support 25, the axial direction of axis pin 35 vertical with the length direction of frame plate 26 by 35 movably arranged of axis pin；Described one
Respectively a pivoting support 25 is passed through to be arranged the first support device 2；Angled oil cylinder 16, angle oil cylinder are installed on frame plate 26
16 output end is connected on the pivoting support 25.The setting of pivoting support 25 is to meet installation the first support dress
First support device 2 is installed on pivoting support 25 by the demand for setting 2, and by pivoting support 25 and 10 movable connection of rack,
It can effectively ensure the stability of 2 operation of the first support device, while also allow for angle oil cylinder 16 and first support device 2 is turned over
The control of gyration.
As shown in figure 3, frame plate 26 is the strip structure of the thin thick middle in both ends, under the downside of 28 rear end of loading plate
Side is provided with the buck plate 29 parallel with loading plate 28, is provided in 26 downside of frame plate and is connect with loading plate 28, buck plate 29
Cant board 27；Wherein, power plant 14 of the installation for driving the crawler belt 1 on buck plate 29, and oil is installed on loading plate 28
Box assembly 9, the fuel tank assembly 9 include providing the fuel tank of fuel oil for power plant 14 and providing hydraulic oil for oil cylinder in the present invention
Oil cylinder.
In order to ensure mast assembly 7 by turning round stability of the pedestal 20 in rotary course, then just needing to make two
First support device 2 keeps absolute synchronization when rotated.For this purpose, in the present solution, 26 front end of frame plate is provided with lazy-tongs 22,
Lazy-tongs 22 are mounted on the lower section of pivoting support 25, and lazy-tongs 22 are connect with first support device of a pair 2；It is described
Overturning oil cylinder 24 be mounted on lazy-tongs 22 on, the output end of overturning oil cylinder 24 passes through force transmission rack 34 and the adjustment axis 18
Connection.Two the first support devices 2 are connected as one by lazy-tongs 22, drive pivoting support 25 to rotate in angle oil cylinder 16
When, due to the effect of lazy-tongs 22, two 2 synchronous rotaries of the first support device will be made, avoiding problems the two rotations to differ
It causes and structural damage caused by possibility, ensures the overall stability of structure.Another effect of lazy-tongs 22 simultaneously is to use
Overturning oil cylinder 24 is installed, a stable mounting platform is provided for overturning oil cylinder 24, makes the installation position of overturning oil cylinder 24
