The specific embodiment
Core of the present utility model provides a kind of tunneling and supporting machine, and it has higher safety performance in the process of supporting operation.
In order to make those skilled in the art person understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 3 and Fig. 4, Fig. 3 provides the structural representation of the main apparent direction of a kind of specific embodiment of tunneling and supporting machine for the utility model; Fig. 4 overlooks the structural representation of direction for tunneling and supporting machine shown in Figure 3.
In a kind of specific embodiment, tunneling and supporting machine provided by the utility model comprises mole 01 and suspension device; Mole 01 can be articulated in the appropriate location of body 02 by jointed shaft, its jointed shaft can be generally along the horizontal direction setting, perhaps slightly being suitable angle ground with horizontal direction is provided with, so that mole 01 can be swung on perpendicular with respect to body 02 around this jointed shaft under the driving of power part; On the body 02 of road heading machinery, be fixedly connected with guiding parts 21, an end of fixedly connected guiding parts 21 on the described body 02, guiding parts 21 can be flexible along the tunneling direction of tunneling and supporting machine, and the other end of guiding parts 21 is equipped with suspension device.
Above-mentioned mole 01 also is not limited to by jointed shaft and is articulated on the body 02, as long as can realize mole 01 swings on perpendicular with respect to body 02, its concrete set-up mode should not be subjected to the restriction of this manual, for example, can also be by certain mount pad is installed between mole 01 and body 02, to realize above-mentioned functions.
Above-mentioned suspension device selectively slides along guiding parts 21 and is meant that suspension device can slide along guiding parts 21, can be static with respect to guiding parts 21 in due course also.It may be noted that at this, between the suspension device body 02 or between guiding parts 21 and the body 02 power part can be installed, oil cylinder etc. for example, suspension device moves forward or backward with respect to body 02 under the effect of this power part, can certainly realize the motion of suspension device with respect to body 02 in other way.
Above-mentioned guiding parts 21 can comprise outer guide 211 and interior guide 212; Outer guide 211 is fixedly connected on described body 02, and interior guide 212 is set in the inside of outer guide 211 slidably, and the end of interior guide 212 is equipped with suspension device.Above-mentioned outer guide 211 can be fixedly connected on body 02 by the mode of welding, also can be connected in the appropriate location of body 02 by bolted mode removably.Concrete, above-mentioned outer guide can with its soffit fixedly connected with body 02 because the length of outer guide 211 is bigger, it is comparatively firm to be installed on body 02 by its soffit, and installation is comparatively convenient; Like this, suspension device can stretch with respect to outer guiding parts under the effect of interior guiding parts, changes to realize its position with respect to body 02.The guide effect of this kind guiding parts and support effect are all better, and structure is comparatively simple, and processing cost is lower.Apparently, above-mentioned outer guide 211 also is not limited to by its soffit and is installed on body 02, also can be installed on the side of body 02 by side; In other embodiment, guiding parts 212 can be fixedly installed in body 02 by certain form in above-mentioned, at this moment, the end of outer guiding parts 211 is connected with suspension device, when outer guiding parts 211 is flexible with respect to interior guiding parts, just flexible with respect to body 02, thus can realize suspension device stretching equally with respect to body 02.
In the another kind of specific embodiment, guiding parts 21 can comprise guiding parts and last guiding parts down; Following guiding parts is fixedly connected on described body 02, the appropriate location of last guiding parts is equipped with suspension device, and one in following guide and the last guide is groove, another person is for to match with this groove, and along the slide block that groove slides, also is, last guiding parts can be the form of groove, this at present guiding parts be and the slide block of groove fit, last guiding parts also can be the form of slide block, this at present guiding parts be the groove that matches with slide block.When suspension device need stretch out forward with respect to body 02, the following guiding device that is connected with body 02 was motionless, and the last guiding device that is connected with payment mechanism stretches out forward with respect to following guiding device.Obvious, last guiding parts can be finished by the power part that is installed on the device appropriate location with respect to the telescopic action of following guiding parts.
Above-mentioned guiding parts 21 can comprise first guiding parts and second guiding parts of the both sides that are installed on described body 02 respectively.Like this, by with respect to body 02 effect of two guiding partss of symmetry substantially, not only improve the reliability of guiding, and suspension device has been formed comparatively firm support, improved the support capacity of suspension device.
It is to be noted, when above-mentioned suspension device is in the supporting state, mole 01 can rotate with respect to described body 02 and be meant, when suspension device is in the supporting state, by design and calculating to the size of guiding device and each structure of suspension device self, can realize suspension device stretch out to mole 01 do not have interference to lower swing, its specific design and calculation mode those skilled in the art should be able to be by oneself.For example guiding parts can be designed to two, be installed in the both sides of body 02 respectively, and when stretching out apart from body 02 distance foremost greater than mole 01 in unidirectional length; The peak that perhaps whole suspension device all is arranged at mole 01 with the plane on etc.
Direction of advance when above-mentioned direction forward is meant the tunneling and supporting machine driving, corresponding, direction backward is meant the direction opposite with above-mentioned direction of advance.Become both sides in the text with the corresponding left and right directions of fore-and-aft direction.
When tunneling and supporting machine is in the driving state, mole 01 work, this moment, suspension device slided to an end opposite with tunneling direction with respect to body 02 along guiding parts; After mole 01 driving is finished, suspension device along guiding device to the distance that it is suitable that tunneling direction slides, and carry out the supporting operation, at this moment, because the supporting operation of suspension device does not need to rely on mole 01 to provide the power that seesaws for it, therefore, suspension device can free mole 01 in the course of the work, make the motion of mole 01 can not be subjected to the restriction of suspension device, this moment, mole 01 can rotate with respect to body 02, so that realize that cutterhead contacts to earth, thereby improved the security performance of tunneling and supporting machine in the supporting operation process.Simultaneously, there are not mutual restriction in the mole 01 of this tunneling and supporting machine and the function of suspension device between finishing, and can realize hocketing of excavation operation and supporting operation, thereby have saved moving the time of equipment, significantly reduce service working time, improved the efficient that the pick nurse does.
Please refer to Fig. 5, and please continue with reference to figure 3 and Fig. 4; Fig. 5 provides the structural representation of a kind of specific embodiment of suspension device in the tunneling and supporting machine for the utility model.
