[0033] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Example 1 like Figure 1-Figure 11As shown, in this embodiment, a hole-forming device for slightly weathered rock foundation in mountainous areas is provided, which includes a pump station trolley, a tower crane, and an excavation mechanism, wherein the tower crane is used to hoist the excavation mechanism, and the excavation mechanism includes a cutting device, a slag suction module assembly for cleaning the slag after cutting, an excavation feed lifting mechanism for the cutting device and for driving the cutting device to lift and lower, and a transmission module assembly for providing cutting power to the cutting device. The above-mentioned pump station trolley, tower crane, and cutting device in the excavation mechanism are all prior art and will not be described in detail here.

[0035] Among them, the slag suction module assembly in this embodiment includes a slag guiding mechanism, and the slag guiding mechanism includes a rotatable slag guide disk 8. A plurality of groups of slag guide plate assemblies 820 are arranged in sequence from the middle to the edge of the slag guide disk 8 on the bottom surface of the slag guide disk 8. Each group of slag guide plate assemblies 820 includes a plurality of slag guide plates 801 and are evenly arranged around the center of the slag guide disk 8. The slag guide plates 801 between adjacent slag guide plate assemblies 820 are arranged with relative end to end spacing. The slag guide plates 801 arranged with relative end to end spacing between the multiple groups of slag guide plate assemblies 820 together constitute a slag guiding blade 802.

[0036] The slag guide plate 8 and the slag guide blades 802 thereon can together constitute a guiding mechanism similar to an impeller. As the cutting device cuts deeper, it will produce slag. Under the rotation of the slag guide plate 8, the slag guide blades 802 use centrifugal force to diffuse the slag in the middle from the center to the periphery, which can effectively avoid the accumulation of slag in the middle, preventing it from affecting the cutting of the cutting device and affecting the suction of the slag by the suction nozzle due to the position of the cutting device.

[0037] Of course, the slag suction module assembly in this embodiment also includes an air suction and slag discharge mechanism, and its structure is basically the same as that in the prior art, including a suction nozzle, a suction pipe and a silo. The suction nozzle is connected to the outer side of the upper part of the silo through the suction pipe, and the top of the silo is connected to the outer side of the lower part of the bag dust collector through a first pipe, and the vacuum pump is connected to the top of the bag dust collector through a second pipe. Thus, the connection between the suction nozzle, the silo, the dust collector and the vacuum pump is realized, and the crushed soil slag is sucked into the silo for storage through the suction nozzle by providing suction force through the vacuum pump.

[0038] In order to better cooperate with the slag guide plate 8, in this embodiment, the suction nozzle 9 can also be designed to be an annular cover with an opening at the lower end to form a suction port. A plurality of evenly arranged connecting pipes 901 are arranged on the annular cover, which are connected to the suction pipe through the connecting pipes. The annular suction nozzle can be installed at the outer periphery of the slag guide plate 8.

[0039] The slag guide plate 8 gathers the slag cut by the cutting device at the central position from the center to the periphery, and then cooperates with the annular cover-shaped suction nozzle to suck the slag gathered at the periphery, which can effectively improve the suction efficiency and degree, so that it can carry out timely cleaning of the slag following the drilling speed of the drill bit.

[0040] In addition, the setting of the slag guide plate 8 can also enable the slag guide plate assembly 820 thereon to further crush the cut slag in the process of gathering the slag toward the periphery, so that it can be more easily sucked and discharged by the suction pipe.

[0041] In this embodiment, in order to enable the slag guide plate assembly 820 to better guide the slag in the middle to the periphery of the guide plate, when designing the slag guide plate assembly 820, the length extension line of the slag guide plate 801 in the slag guide plate assembly 820 near the middle of the slag guide plate 8 is eccentrically set to the center of the slag guide plate 8, and the distance between the length extension line of the slag guide plates 801 in the multiple groups of slag guide plate assemblies 820 arranged sequentially from the middle to the edge of the slag guide plate 8 and the center of the slag guide plate 8 gradually increases, so that the slag guiding blade 802 is constructed into a curved arc shape, that is, the slag guiding blade 802 is formed into a curved arc blade shape as a whole, which has a better slag guiding effect.

[0042] In this embodiment, the slag guide plate 8 includes a lower plate body 803 and an upper plate cover 804, and a buffer cavity 805 is formed between the lower plate body 803 and the upper plate cover 804. One end of the slag guide plate 801 is arranged in the buffer cavity 805, and the other end extends out of the buffer cavity 805 through the bottom surface of the lower plate body 803. A guide plate buffer spring 806 is provided in the buffer cavity 805 for buffering the slag guide plate 801 in the extending direction.

[0043] Among them, a spring guide column 807 corresponding to the slag guide plate 801 is arranged on the lower end of the upper plate cover 804, and the guide plate buffer spring 806 is sleeved on the spring guide column 807. The slag guide plate 801 includes a guide column connecting plate 808 arranged in the buffer cavity 805 and a slag moving plate 809 extending out of the buffer cavity 805. The slag moving plate 809 is vertically arranged, and the guide column connecting plate 808 is horizontally arranged; the lower end of the spring guide column 807 passes through the guide column connecting plate 808, and a moving plate extending port 810 is provided on the bottom surface of the lower plate body 803 for the slag moving plate 809 to extend out and to slide with the slag moving plate 809.

[0044] The guide plate buffer spring 806 arranged in the slag guide plate 8 can enable the slag guide plate 801 to retreat when encountering a large piece of slag when guiding the slag, thereby preventing the slag guide blade 802 from getting stuck; and the structural design of the slag guide plate 8 can make the guide plate buffer spring 806 and the slag guide plate assembly 820 inside it more convenient to install.

[0045] In this embodiment, the slag suction module assembly includes a guide plate driving mechanism for driving the slag guide plate 8 to rotate, and the guide plate driving mechanism includes a transmission module assembly, and the transmission module assembly includes a first transmission box 1, and the first transmission box 1 is provided with a first input shaft 2 for connecting to a hydraulic motor, a first output shaft 3 for driving a cutting device to rotate, and a first transmission gear set 4 for realizing transmission between the first input shaft 2 and the first output shaft 3. It is characterized in that it also includes a second input shaft 5 arranged at the first transmission box 1 and used to provide power to the first output shaft 3, and the second input shaft 5 can drive the first output shaft 3 to rotate through the first transmission gear set 4.

[0046] The second input shaft 5 and the second input shaft 5 are respectively arranged on both sides of the first transmission box 1 and are both arranged horizontally. The power provided by the second input shaft 5 to the first output shaft 3 is the same as or opposite to the power provided by the first input shaft 2 to the first output shaft 3.

[0047] First of all, the transmission module assembly in this embodiment can realize dual-axis input to the cutting device, and a hydraulic motor is respectively arranged at the first input shaft 2 and the second input shaft 5, so that the two input shafts can operate independently. Through this dual power input, they can backup each other, effectively improving the fault tolerance rate brought about by the drilling process, and ensuring the normal and stable progress of the drilling process.

[0048] In order to realize the coordinated work of the two input shafts, dual power input is realized based on the planetary gear in this embodiment. Specifically, the first transmission gear set 4 includes a gear mounting frame 401 fixed to the inner wall of the first transmission case 1, and a planetary gear set is installed on the gear mounting frame 401. The planetary gear set includes a sun gear 402 arranged on the first output shaft 3, a plurality of planetary gears 403 meshing with the sun gear 402, and a planetary carrier 404 for mounting the planetary gears 403; The first transmission gear set 4 also includes a first input wheel 405 arranged on the first input shaft 2, a second input wheel 406 arranged on the second input shaft 5, and a first bevel gear 407 and a second bevel gear 408 arranged coaxially with the sun gear 402. The inner wall of the first bevel gear 407 is provided with a ring gear 412 meshing with the planetary gear 403, and the outer wall is meshed with the first input wheel 405. The second bevel gear 408 is driven by the second input wheel 406, and the planet carrier 404 is fixed to the inner wall of the second bevel gear 408.

[0049] The first transmission gear set 4 further includes a second output shaft 409 arranged at the first transmission box 1 and parallel to the second input shaft 5 . The second output shaft 409 is provided with a second output wheel 410 meshing with the second input wheel 406 and a third bevel gear 411 meshing with the second bevel gear 408 .

[0050] In this embodiment, a worm gear 813 is provided at the end of the second output shaft 409 away from the third bevel gear 411, and the second transmission gear set 812 includes a turbine 814 meshing with the worm gear 813. A longitudinally arranged connecting shaft 815 is provided in the middle of the turbine 814, and a first gear 816 is installed on the connecting shaft 815. A connecting sleeve 817 is provided on the outside of the first output shaft 3, and the connecting sleeve 817 can rotate outside the first output shaft 3 and a second gear 818 is installed on the connecting sleeve 817. A third gear 819 is connected between the first gear 816 and the second gear 818. The first gear 816, the second gear 818 and the third gear 819 are all arranged in the second transmission box 811, and the bottom of the connecting sleeve 817 is fixed on the upper end surface of the slag guide plate 8, and the first output shaft 3 passes through the slag guide plate 8 and the end thereof is passed out for connecting the cutting device.

[0051] In the present embodiment, on the one hand, the slag guide disc 8 is coaxially arranged with the cutting device, and the cutting device is arranged below the slag guide disc 8 and located in the middle of the slag guide blade 802. On the other hand, the power of the second input shaft 5 is drawn out and supplied to the slag guide disc 8 through the structure of the turbine 814 worm gear, which can ensure that the slag in the middle can be cleaned in time without setting up another transmission mechanism. The structure has been optimized, and the overall transmission mechanism has a compact and small structure, which can be better suitable for underground operations.

[0052] Based on planetary gears and two transmission gear sets, it can be flexibly applied to different working conditions at different drilling positions during the drilling process, so as to truly realize automatic excavation without people going down the pit. The specific working conditions it can adapt to are as follows: 1 controls the first input shaft 2 and the second input shaft 5 to rotate in the same direction, and provides the first output shaft 3 with the same power. At this time, the two input shafts provide the same and opposite power to offset the power of the first output shaft 3. At this time, the first output shaft 3 does not rotate, that is, the cutting head is in a non-cutting state; due to the rotation of the second input shaft 5, it can drive the second output shaft 409 to rotate, and then realize the rotation of the slag guide plate 8, that is, at this time, the slag guide is in a working state.

[0053] 2. Control the first input shaft 2 to rotate, and the second input shaft 5 to remain stationary, so that the first output shaft 3 can be rotated, that is, the cutting head is in the cutting state, and the second output shaft 409 is stationary, and the slag guide is in the non-working state; 3 By controlling the first input shaft 2 and the second input shaft 5 to rotate in opposite directions, the two input shafts provide the same power to the first input shaft 2 to achieve power synthesis, so that the first output shaft 3 can rotate quickly and the slag guide plate 8 can rotate relatively slowly; 4 controls the first input shaft 2 and the second input shaft 5 to rotate in the same direction, and provides different magnitudes of power to the first output shaft 3. At this time, the two input shafts provide opposite power to achieve partial offset of the power of the first output shaft 3. At this time, the first output shaft 3 rotates slowly, and the slag guide plate 8 rotates relatively quickly; 5 controls the rotation speed of the first input shaft 2 and the second input shaft 5, and controls the first output shaft 3 to rotate at the same speed as the slag guide plate 8.

[0054] In order to further achieve better cutting, this embodiment also includes a coupling mechanism 6 for connecting the cutting device to the first output shaft 3. The coupling mechanism 6 includes a connecting portion 601 and a mounting portion 602. The connecting portion 601 is arranged on a plug-in hole 603 for plugging the first output shaft 3, and the mounting portion 602 is arranged on a mounting flange 604 for mounting the cutting device, wherein the cross-sections of the plug-in hole 603 and the first output shaft 3 are both regular hexagons to achieve rotation limiting.

[0055] The coupling mechanism 6 also includes a sleeve member 605 arranged between the connecting portion 601 and the mounting portion 602. The end of the connecting portion 601 away from the plug-in hole 603 is arranged in the sleeve member 605 and slidably cooperates with the inner wall of the sleeve member 605. A plurality of first springs 606 are arranged axially parallel to the axial direction of the sleeve member 605 on the end surface of the mounting portion 602. The first springs 606 have a tendency to drive the connecting portion 601 to move toward the first output shaft 3.

[0056] The coupling mechanism 6 can realize an elastic connection between the first output shaft 3 and the cutting device in the axial direction, provide an escape space for the drill bit during the drilling process of the rock foundation, and facilitate the smooth progress of the drilling operation.

[0057] In this embodiment, a spring force adjustment mechanism is also provided in the sleeve member 605, and the spring force adjustment mechanism includes a connecting rod 607 with one end coaxially threadedly connected to the connecting portion 601, and the other end of the connecting rod 607 is arranged on the spring connecting disk 608. A plurality of spring guide columns 609 passing through the spring connecting disk 608 are arranged on the end surface of the mounting portion 602, and the first spring 606 is sleeved on the spring guide columns 609.

[0058] The setting of the spring force adjustment mechanism can realize the adjustment of the elastic force of the coupling mechanism 6, that is, the position of the connecting rod 607 relative to the connecting part 601 is realized through the threaded connection between the connecting rod 607 and the connecting part 601, and then the adjustment of the elastic force of the first spring 606 is realized, so that the drill bit has appropriate buffering force and can be suitable for different geological conditions.

[0059] In this embodiment, a partition 610 is provided in the sleeve member 605, and the partition 610 divides the interior of the sleeve member 605 into an upper chamber 611 and a lower chamber 612. The connecting part 601 is arranged in the upper chamber 611, the spring connecting plate 608 is arranged in the lower chamber 612, and the connecting rod 607 passes through the partition 610.

[0060] The connecting portion 601 includes a first rod segment 613 and a second rod segment 614. The outer diameter of the second rod segment 614 is larger than that of the first rod segment 613. The plug-in hole 603 is arranged on the end face of the first rod segment 613 away from the second rod segment 614. The second rod segment 614 is arranged inside the sleeve member 605. The end of the sleeve member 605 is constructed with a circular ring portion 615 whose inner wall slides with the first rod segment 613. A plurality of fixing screws 616 passing through the second rod segment 614 are evenly arranged on the circular ring portion 615. The middle portion of the fixing screw 616 is a smooth section and the end portion is a threaded section. The partition plate 610 is provided with a threaded hole 617 for threaded connection of the fixing screw 616.

[0061] The connection of multiple fixed screws 616 in the coupling mechanism 6 can effectively prevent the connection part 601 from rotating, thereby ensuring the stability of the threaded connection between the connection part 601 and the connecting rod 607. At the same time, the sliding cooperation between the connection part 601 and the sleeve member 605, the sliding cooperation between the connecting rod 607 and the partition 610, and the sliding cooperation between the spring guide column 609 and the partition 610, etc., can together constitute a multi-stage guide of the coupling mechanism 6, effectively preventing the radial deviation of the coupling mechanism 6.

[0062] In addition, the separation design of the upper chamber 611 and the lower chamber 612 can ensure that when the slag guide plate 8 is guiding and cleaning the slag, fine slag will not enter the coupling mechanism 6 but will hardly enter the lower chamber 612 having the first spring 606, thereby ensuring the service life of the first spring 606.

[0063] Finally, the slag guiding mechanism in the slag suction module assembly, the transmission module assembly, and the hydraulic motor, gear set, coupling mechanism 6 in the transmission module assembly in this embodiment are all modularly designed and can be disassembled and installed on site, which is convenient for transportation in mountainous areas and can be better applied to slightly weathered rock foundations in mountainous areas.
