In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The shaft heading machine provided by the embodiment of the invention is shown in the attached figures 1 to 3 of the specification, and comprises: the device comprises a main drive 2, a cutter head 3, a down-the-hole hammer 7, an outer down-the-hole hammer barrel 6, a slag-out bucket 9 and an air system 8.
The main drive 2 is used as a main power supply element for driving the cutter head 3 and the down-the-hole hammer 7 to rotate, the main drive 2 and the cutter head 3 can be directly connected, the main drive 2 and the down-the-hole hammer 7 can be connected through the down-the-hole hammer outer cylinder 6, namely, the down-the-hole hammer outer cylinder 6 is sleeved outside the down-the-hole hammer 7, and the outer cylinder 6 of the down-the-hole hammer and the down-the-hole hammer 7 keep relatively static, when the main drive 2 drives the outer cylinder 6 of the down-the-hole hammer to rotate, the down-the-hole hammer 7 rotates synchronously with the outer cylinder 6 of the down-the-hole hammer, namely, the driving mechanisms of the cutter head 3 and the down-the-hole hammer 7 are the same and are the main drive 2.
The down-the-hole hammer 7 is arranged along the vertical direction and used for conducting pilot excavation, the cutter head 3 is sleeved on the outer side of the down-the-hole hammer outer barrel 6, and a certain distance is reserved between the cutter head 3 and the bottom end of the down-the-hole hammer 7, so that when the down-the-hole hammer 7 excavates downwards to a certain depth, expanding excavation is conducted through the cutter head 3.
The internal of down-the-hole hammer 7 is located to the well bucket 9 that slags tap, and well bucket 9 that slags tap can follow the axial displacement of down-the-hole hammer 7, also the well bucket 9 that slags tap can follow vertical direction and reciprocate. Of course, in order to move the slag tapping bucket 9 up and down, the slag tapping bucket 9 may be suspended by a driving mechanism such as a cable to move the slag tapping bucket 9.
The outer cylinder 6 of the down-the-hole hammer is provided with a gate 11 which can be opened and closed, and the gate 11 can be operated and controlled by a panel to realize opening and closing; the blade disc 3 is located the position department of gate 11, and when gate 11 opened, the dregs that blade disc 3 expanded and dug can get into the inside of down-the-hole hammer 7 behind gate 11 to accepted by the well-bucket 9 of slagging tap, transported the dregs outside the hole through well-bucket 9 of slagging tap at last.
When pilot excavation is carried out, the control gate 11 is closed, the main drive 2 drives the down-the-hole hammer 7 to rotate at a first speed, the main drive 2 can be regarded as driving the down-the-hole hammer 7 to rotate at a high speed, the cutter head 3 can also rotate, and the down-the-hole hammer 7 tunnels forwards, namely the down-the-hole hammer 7 moves downwards to realize excavation; the dregs dug by the down-the-hole hammer 7 enter the down-the-hole hammer 7 from the bottom end of the down-the-hole hammer 7, and the air system 8 conveys high-pressure air to the inside of the down-the-hole hammer 7, so that the dregs entering the inside of the down-the-hole hammer 7 are blown up and then blown into the dreg-discharging bucket 9.
It can be seen that in pilot excavation, although the cutterhead 3 is rotated, the down-the-hole hammer 7 is the component which enables the pilot excavation, and the muck excavated by the down-the-hole hammer 7 is carried to the ground by means of a muck bucket 9 located inside the down-the-hole hammer 7.
When expanding excavation, the gate 11 is controlled to be opened, the main drive 2 drives the cutter head 3 to rotate at a second speed, the main drive 2 can drive the cutter head 3 to rotate at a low speed, the down-hole hammer 7 can also rotate, and the cutter head 3 tunnels forwards, namely the cutter head 3 moves downwards, so that expanding excavation is realized; because the cutter head 3 is positioned at the position of the gate 11, the slag dug by the cutter head 3 can enter the inside of the down-the-hole hammer 7 through the gate 11, and then fall into the slag-discharging bucket 9, and finally the slag is conveyed to the ground by the slag-discharging bucket 9.
It can be seen that, in reaming, the cutterhead 3 is the component that performs reaming, although the down-the-hole hammer 7 rotates; and no matter in leading excavation or expanding excavation stage, all rely on the drive of main drive 2 to all rely on slagging tap bucket 9 to realize slagging tap. The shaft heading machine can realize pilot excavation and expanding excavation operation, also can realize two different construction operations, and then make the excavation depth of shaft obtain showing and promote, in addition, this paper merges two different operating modes, integrates into a shaft heading machine, has greatly promoted the efficiency of construction to help reducing the degree of difficulty of construction.
The shaft boring machine herein further comprises a shoe 4, the shoe 4 being used to brace the wall of the hole, and the shoe 4 being located above the main drive 2.
It can be seen that the shaft heading machine can realize the function of tightly supporting the wall of the hole in the stages of pilot excavation and extended excavation only by using one group of supporting shoes 4, and compared with deep well heading equipment in the prior art, the pilot excavation and extended excavation respectively use two sets of driving and tightly supporting systems, so that the structure is complex. The shaft heading machine adopts a set of driving and supporting systems for pilot heading and expanding excavation, leads the slag to be discharged and expanded and excavated through the cooperation of the gate, and has simple structure.
In order to realize the forward tunneling function of the cutterhead 3, a first pushing part 12 is arranged between the supporting shoes 4 and the main drive 2, and when the cutterhead 3 is driven to tunnel forwards through the first pushing part 12.
Because the position of the supporting shoe 4 relative to the tunnel wall is fixed, the first pushing part 12 takes the supporting shoe 4 as a reference to push the main drive 2 and the cutter head 3 to synchronously tunnel forwards, that is, the cutter head 3 can tunnel forwards under the action of the first pushing part 12 while rotating under the action of the main drive 2, and further the expanding tunneling is completed.
And a second pushing part 5 is arranged between the supporting shoe 4 and the outer cylinder 6 of the down-the-hole hammer, and when the excavation is conducted, the down-the-hole hammer 7 is driven to advance through the second pushing part 5.
Similarly to the above, the position of the supporting shoe 4 relative to the hole wall is fixed, so the second pushing part 5 directly pushes the outer cylinder 6 of the down-the-hole hammer to advance based on the supporting shoe 4, and meanwhile, because the outer cylinder 6 of the down-the-hole hammer is connected with the main drive 2, and the relative positions of the outer cylinder 6 of the down-the-hole hammer and the down-the-hole hammer 7 are fixed, the second pushing part 5 applies thrust to the down-the-hole hammer 7, so that the down-the-hole hammer 7 advances, and then the pilot excavation is completed.
The first pushing part 12 and the second pushing part 5 may be embodied as piston cylinders such as oil cylinders, the cylinder seats of which may be fixed to the supporting shoes 4, and the piston rods of which may be fixed to the main drive 2 and the outer barrel 6 of the down-the-hole hammer, respectively, so as to implement two different types of tunneling processes.
The shaft boring machine further comprises a relay bucket 10, the relay bucket 10 is arranged in the hole, the relay bucket 10 is located on the outer side of the down-the-hole hammer 7, the relay bucket 10 can move along the axial direction of the down-the-hole hammer 7, and the relay bucket 10 is located above the slag discharging bucket 9.
In order to avoid overhigh lifting height of the slag-tapping bucket 9 no matter in the stage of pilot excavation or expanding excavation, when the slag-tapping bucket 9 is lifted to be parallel to the height of the relay bucket 10, the slag-tapping bucket 9 can be controlled to dump the slag in the slag-tapping bucket 9 into the relay bucket 10, and the relay bucket 10 conveys the slag to the ground, namely, the slag is conveyed to the ground in a relay manner; the slag bucket 9 is lowered below the gate 11 to continue to receive the slag.
When the excavation is guided first, high-pressure air is supplied to the inside of the down-the-hole hammer 7 through the air system 8, so that the slag excavated by the down-the-hole hammer 7 is blown into the slag bucket 9 and/or the relay bucket 10. That is, under the action of the air system 8, the slag may be blown into the slag bucket 9 and the relay bucket 10 simultaneously, and the relay bucket 10 may bear a part of the weight.
When the slag removing bucket 9 is fully filled with the slag excavated by the cutter head 3, the slag can be lifted and poured into the relay bucket 10, and the slag can be transported to the ground by the relay bucket 10, as mentioned above. It can be seen that under the action of the air system 8, the slag can be discharged under two different working conditions by utilizing the slag bucket 9, and the requirement on the particle size of the slag is not required.
The relay bucket 10 can be located above the supporting shoes 4, that is, under the limiting action of the supporting shoes 4, the relay bucket 10 cannot move downwards continuously, and the slag discharging bucket 9 is located inside the down-the-hole hammer 7 and is not limited by the positions of the supporting shoes 4, so that the slag discharging bucket 9 and the relay bucket 10 play a good complementary role, and the slag discharging efficiency is improved.
The shaft boring machine further comprises a drilling rig 1 for location on the ground, an air system 8 being provided in the drilling rig 1, the air system 8 being arranged to convey high pressure air down the interior of the down-the-hole hammer 7.
Obviously, the drilling frame 1 can be regarded as an installation reference of the shaft boring machine and can be directly fixed on the ground, and the air system 8 is installed in the drilling frame 1, so that the air system 8 can be timely overhauled and maintained, and the normal operation of the shaft boring machine is ensured.
In combination with the above, the slag discharging bucket 9 and the relay bucket 10 can both be lifted and lowered by the driving mechanism, and the driving mechanism can also control the dumping of the slag discharging bucket 9 for the slag discharging bucket 9, that is, dumping the slag soil in the slag discharging bucket 9 into the relay bucket 10, and the driving mechanism is preferably arranged in the drill frame 1, so that the maintenance is convenient.
The vertical shaft heading machine utilizes the main drive 2 to drive the down-the-hole hammer 7 and the cutter head 3 simultaneously, so that two different working conditions are realized, and when one of the down-the-hole hammer 7 and the cutter head 3 rotates, the other mechanism also rotates along with the rotation; in addition, the same set of supporting shoes 4 are used simultaneously, and compared with the prior art that two sets of tunneling systems and two sets of slag discharging systems are respectively adopted, the vertical shaft tunneling machine is obviously simple in structure and easy to install and maintain.
