Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A tunneling apparatus 100 according to an embodiment of the present invention is described below with reference to the drawings.
As shown in fig. 1 and 2, a tunneling apparatus 100 according to an embodiment of the present invention includes a tunneling and anchoring all-in-one machine 1, a reversed loader 2, a dust removing device 3, and an air supply device 4.
The front end part of the driving and anchoring all-in-one machine 1 is provided with a cutting part 11, and the cutting part 11 is used for cutting the ore body in front of the driving and anchoring all-in-one machine 1.
The reversed loader 2 is positioned at the rear part of the tunneling and anchoring all-in-one machine 1, and the reversed loader 2 is matched with the tunneling and anchoring all-in-one machine 1 so that ore bodies cut by the tunneling and anchoring all-in-one machine 1 can be conveyed out of a roadway. In the process of driving of the driving and anchoring integrated machine 1, the reversed loader 2 advances along with the driving and anchoring integrated machine 1 and has a certain distance with the driving and anchoring integrated machine 1.
The dust removing device 3 has an inlet 301 and an outlet 302. The dust removing device 3 is mounted on one of the machine 1 and the reversed loader 2 so that the inlet 301 of the dust removing device 3 has a first preset distance from the cutting part 11. That is, the inlet 301 of the dust removing device 3 moves with one of the driving and bolting unitary machine 1 and the reversed loader 2, so that the distance between the inlet 301 of the dust removing device 3 and the cutting part 11 (the position where dust is much) can be made constant. Therefore, the inlet 301 of the dust removing device 3 is located at a position with more dust, so that the dust removing effect of the dust removing device 3 is good.
The air supply device 4 comprises a first air duct 41 and a second air duct 42, wherein an inlet 411 of the first air duct 41 is communicated with the second air duct 42, so that air in the second air duct 42 enters the first air duct 41.
The first air duct 41 is arranged on one of the tunneling and anchoring all-in-one machine 1 and the reversed loader 2, and the outlet 412 of the first air duct 41 has a second preset distance with the cutting part 11. That is, the outlet 412 of the first air duct 41 moves with one of the driving and bolting machine 1 and the reversed loader 2 so that the distance between the outlet 412 of the first air duct 41 and the cutting part 11 is constant. Therefore, the air body of the air curtain which comes out of the outlet 412 of the first air duct 41 and is formed can be pressed to the dust at a proper position, the dust is prevented from diffusing backwards, the ventilation effect is good, and the installation performance of tunneling work is improved.
The second air duct 42 is retractable along the length direction thereof and connected to the reversed loader 2, so that the second air duct 42 is extended by the reversed loader 2. Specifically, the second air duct 42 is retractable in the front-rear direction and connected to the reversed loader 2, a first portion of the second air duct 42 is in a retracted state, one end of the first portion of the second air duct 42 is mounted on the reversed loader 2, a second portion of the second air duct 42 is in an extended state, and a first portion of the second air duct 422 is gradually extended under the driving of the reversed loader 2 so as to increase the length of the second air duct 42 in the front-rear direction. For example, a first portion of the second air duct 42 is located at the rear side of the first air duct 41, and a second portion of the second air duct 42 is in an extended state and connected to a ventilation device so that air is introduced into the first air duct 41 from the rear of the second air duct 42. During the advancing process of the reversed loader 2, a first part of the front part of the second air duct 42 is gradually extended so as to increase the length of the second air duct 42, so that the second air duct 42 is not broken and can continuously supply air when the reversed loader 2 advances.
According to the roadway driving equipment 100 provided by the embodiment of the invention, the inlet 301 of the dust removing device 3 is arranged at the first preset distance from the cutting part 11, so that the inlet 301 of the dust removing device 3 is positioned at a position convenient for absorbing dust, and the dust removing effect of the dust removing device 3 is improved. The outlet 412 of the first air duct 41 has a second preset distance with the cutting part 11, so that the air pressure of the air curtain coming out of the outlet 412 of the first air duct 41 and formed towards the dust is fixed, and the effect of preventing the dust from diffusing backwards is better. And the first portion of the second air duct 42 is in a contracted state, the first portion of the second air duct 42 is gradually extended as the reversed loader 2 advances. Therefore, in the tunneling process, the air duct does not need to be added frequently, the workload caused by adding the air duct can be increased, the time is saved, and the tunneling efficiency is improved.
Therefore, the tunneling device 100 according to the embodiment of the present invention has the advantages of good dust removal effect, good ventilation effect, high safety, and high tunneling efficiency.
As shown in fig. 1, in some embodiments, the inlet 301 of the dust removing device 3 is installed on the all-in-one machine 1, and specifically, the inlet 301 of the dust removing device 3 is installed at the front end portion of the all-in-one machine 1, so that the inlet 301 of the dust removing device 3 can rapidly absorb dust at the cutting part 11, thereby improving the dust removing effect of the dust removing device 3.
The outlet 412 of the first air duct 41 is arranged at the front end part of the reversed loader 2, so that the air from the outlet 412 of the first air duct 41 is pressed towards the tunneling and anchoring integrated machine 1, and the dust at the tunneling and anchoring integrated machine 1 is pressed towards the front end part of the tunneling and anchoring integrated machine 1, so that the dust removing device 3 can remove dust.
As shown in fig. 1, in some embodiments, the dust removing device 3 includes a dust remover 31 and a dust removing air duct 32.
The inlet of the dust-removing air duct 32 forms the inlet 301 of the dust-removing device 3, and the outlet of the dust-removing air duct 32 is connected to the dust remover 31.

The dust catcher 31 is mounted on the reversed loader 2, i.e. the dust catcher 31 can advance with the reversed loader 2. The inlet of the dust removing air duct 32 is installed on the machine 1, so that the inlet of the dust removing air duct 32 can advance along with the machine 1, and the inlet of the dust removing air duct 32 has a first preset distance from the cutting part 11, and the dust removing air duct 32 can absorb dust conveniently.
In some embodiments, in the cross-section of the dust extraction air duct 32, the dust extraction air duct 32 has a width and a height, and the width of the dust extraction air duct 32 is greater than the height of the dust extraction air duct 32. Specifically, the dust removal duct 32 is located on the upper side of the reversed loader 2 and the integrated machine 1. Therefore, the distance between the dust removing air duct 32 and the top of the roadway is short, and in order to ensure that the dust removing air duct 32 does not collide with the top of the roadway, certain limitation needs to be made on the height of the dust removing air duct 32. Under the condition that the height is not changed, the width of the dust removing air duct 32 is larger than the height of the dust removing air duct 32, so that the cross-sectional area of the dust removing air duct 32 can be increased, the size of the cavity of the dust removing air duct 32 is increased, and dust can conveniently enter the dust remover 331 through the dust removing air duct 32. For example, the dust exhaust duct 32 has a rectangular shape whose length in the horizontal direction is larger than that in the vertical direction.
In some embodiments, as shown in fig. 1, dust extraction duct 32 includes a first sub-dust extraction duct 321 and a plurality of second sub-dust extraction ducts 322.
