Description

Technical Field

[0001] The invention relates to the technical field of base drilling, in particular to construction foundation drilling equipment. Background Art

[0002] Building foundations are mainly divided into two types: natural foundations and artificial foundations. Natural foundations refer to foundations that can directly bear all or most of the loads of a building without special treatment or improvement. Artificial foundations refer to foundations that have insufficient bearing capacity or other unfavorable conditions and need to be treated through foundation treatment technology to improve their bearing capacity and stability, thereby meeting the building's foundation requirements.

[0003] The artificial foundation of a building is particularly important and is directly related to whether the building is safe. When the foundation is being constructed, it is necessary to pre-mark the treated foundation, and then drill holes at each mark for subsequent use of a drilling machine to drill holes and bury piles. A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave cylindrical holes or holes on the target object through rotary cutting or rotary extrusion.

[0004] The foundation drilling device currently used in construction discharges soil around the borehole through spiral blades and accumulates it on the surface during drilling. The soil accumulation around the borehole is relatively high. When the drill bit withdraws from the borehole, the soil at a high position tends to fall into the borehole again, resulting in a large error between the actual depth of the borehole and the expected depth, thereby affecting the stability of the foundation. In addition, when there are large stones inside the soil layer, the vibration causes the main body of the drilling device to move, resulting in a large drilling deviation, thereby affecting the positioning accuracy of the drilling device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When drilling holes in construction, the sliding ring can be squeezed by the connecting column, and then the sliding ring will drive the rotating plate to move upward, so that the rotating plate drives the connecting block to move outward through the first rotating shaft. At this time, the sliding block will move outward along the outer wall of the fixed rod, and then the first spring will be squeezed.

When the drill bit encounters a harder stone, the drilling problem caused by the displacement of the main body of the drilling device due to large vibration is avoided, which affects the positioning accuracy of the drilling device, thereby extending the service life of the drill bit.

[0020] 2. After drilling a hole in the construction, when the drill bit withdraws from the inside of the borehole, the slide bar will slide along the inclined groove of the third slide groove, thereby driving the push plate to slide and reset along the inside of the inner groove. During the sliding process, the push plate will push the soil inside the inner groove into the transmission box, and then the soil enters the collection box through the connecting hose, completing the collection of the soil generated by the drilling. At the same time, when the drill bit withdraws from the inside of the borehole, the soil will no longer fall into the borehole, ensuring that the actual depth of the borehole is consistent with the expected depth, thereby improving the work quality.

[0021] 3. After drilling holes in the construction, when the push plate drags the soil inside the inner groove, the water flow inside the water storage pipe is squeezed through the squeezing ring, so that the water flows into the mounting block through the water guide pipe, and then is sprayed out through the nozzle, thereby realizing water spray cleaning inside the inner groove, which can loosen the soil and make subsequent cleaning work easier.

The end of the shaft 407 that is away from the second shaft 409 is rotatably connected, and the outer wall of the second shaft 409 is fixedly connected to the side wall of the sliding ring 410, the top of the sliding ring 410 is fixedly connected to the bottom of the second spring 411, and the top of the second spring 411 is fixedly connected to the bottom of the fixed ring 402, the bottom of the sliding ring 410 is fixedly connected to a connecting column 412, and the end of the connecting column 412 that is away from the second shaft 409 is fixedly connected to the top of the drill bit 413, a first sliding groove 415 is provided at the bottom of the rotating rod 401, the outer wall of the connecting column 412 is fixedly connected to the limiting plate 414, and the outer wall of the limiting plate 414 is slidably connected to the inner wall of the first sliding groove 415, and the outer wall of the rotating rod 401 is fixedly connected to a spiral leaf 416;

[0035] More specifically, in this embodiment, before drilling is required for construction, the equipment is first pushed to the work area where drilling is required. The universal wheel 13 is provided to facilitate the drilling work, so that the equipment can be quickly moved in different construction positions. After moving to the construction position, the drill bit 413 is then aligned with the mark where drilling is required, and then the hydraulic jack 14 is started to raise the equipment. After the lifting, the universal wheel 13 will be off the ground, and the hydraulic jack 14 will support the equipment, so that the equipment can be better balanced, which is more stable for the subsequent drilling work, and then the drilling work can be carried out;

[0036] By driving the first motor 6, the damping drill mechanism 4 of the output shaft can be driven to rotate at high speed, thereby driving the limit plate 414 on the inner wall of the first slide groove 415 to rotate through the rotating rod 401, and then the limit plate 414 will drive the drill 413 to rotate at high speed through the connecting column 412. By setting the limit plate 414 to slide on the inner wall of the first slide groove 415, the drill 413 can rotate synchronously with the rotating rod 401. Then drive the second motor 7 to rotate the stud 2 of the output shaft, which is threadedly connected to the outer wall of the stud 2 through the connecting plate 3. Therefore, when the stud 2 rotates, the connecting plate 3 will slide downward along the inner wall of the connecting tube 1, and then drive the first motor 6 to move downward at the same time. Then the first motor 6 will drive the damping drill mechanism 4 to move downward. After the damping drill mechanism 4 moves a certain distance, the drill 413 will contact the ground, and then the high-speed rotating drill 413 will hit the ground. The drill bit 413 is squeezed and then continuously moved downward to achieve the effect of drilling. If the drill bit 413 encounters a larger stone inside the soil layer and is not crushed at the first time, the drill bit 413 will be forced to slide toward the inside of the rotating rod 401, and then the connecting column 412 will squeeze the sliding ring 410, and then the sliding ring 410 will move upward. During the movement, the rotating plate 408 will be driven to move upward, so that the rotating plate 408 drives the connecting block 406 to translate outward through the first rotating shaft 407. At this time, the sliding block 404 will move outward along the outer wall of the fixed rod 403, and then the first spring 405 will be squeezed. At the same time, a second spring 411 is provided between the fixed ring 402 and the sliding ring 410, so when the sliding ring 410 moves, the second spring 411 will also be squeezed, and the upward movement of the drill bit 413 can provide a buffering force for the drill bit 413;

[0037] As described above, the connecting column 412 will squeeze the sliding ring 410, and then the sliding ring 410 will drive the rotating plate 408 to move upward, so that the rotating plate 408 drives the connecting block 406 to translate outward through the first rotating shaft 407. At this time, the sliding block 404 will move outward along the outer wall of the fixed rod 403, and then the first spring 405 will be squeezed. The drill bit 413 can move upward to provide a buffering force for the drill bit 413. When the drill bit 413 encounters a harder stone, the drilling problem caused by the displacement of the drilling device body due to large vibrations is avoided, which affects the positioning accuracy of the drilling device, thereby extending the service life of the drill bit 413.

[0038] Embodiment 2: Based on the above embodiment, a collecting mechanism 5 is provided at the bottom of the connecting plate 3 to collect the soil generated by drilling holes during construction;

[0039] Furthermore, the collecting mechanism 5 includes a connecting box 501, and the top of the connecting box 501 is fixedly connected to the bottom of the connecting plate 3, the top of the connecting box 501 is penetrated with a through hole 502, and the inner wall of the through hole 502 is fixedly connected to the outer wall of the rotating rod 401, the side wall of the connecting box 501 is provided with an inner groove 503, and the side wall of the inner groove 503 is slidably connected with a push plate 505, and the side wall of the push plate 505 is fixedly connected with a third spring 504, and the third spring 504 and the push plate 505 are fixedly connected. The end of the plate 505 that is away from each other is fixedly connected to the side wall of the inner groove 503, the side wall of the push plate 505 is fixedly connected to the slide bar 506, the inner wall of the connection port 508 is fixedly connected to the transmission cylinder 15, and the inner wall of the transmission cylinder 15 corresponds to the outer wall of the spiral leaf 416, the second motor 7 is fixedly installed on the top of the inner wall of the connection cylinder 1, and the output shaft of the second motor 7 is fixedly connected to the top of the stud 2, the water spray mechanism 16 includes a water storage pipe 1601, and the inner wall of the water storage pipe 1601 The extrusion ring 1602 is slidably connected to the side wall of the extrusion ring 1602, and the connecting rod 1603 is fixedly connected to the end of the connecting rod 1603 away from the extrusion ring 1602, and the sleeve 1604 is fixedly connected to the end of the sleeve 1604, and the inner cavity 1605 is penetrated and opened, and the inner wall of the inner cavity 1605 is fixedly connected to the water pipe 1606, and the end of the water pipe 1606 close to the inner cavity 1605 is fixedly connected to the fourth spring 1607, and the fourth spring 1 One end of the water pipe 1607 away from the water pipe 1606 is fixedly connected with a stopper 1608, the outer wall of the stopper 1608 is slidably connected to the inner wall of the inner cavity 1605, one end of the water pipe 1606 away from the inner cavity 1605 is fixedly connected with a mounting block 1609, and a nozzle 1610 is fixedly installed on the side wall of the mounting block 1609, the top of the water storage pipe 1601 is fixedly connected with a connecting pipe 1611, and the top of the connecting pipe 1611 is fixedly connected with a water tank 1612;

[0040] In this embodiment, during the process of drilling holes in construction, the connecting box 501 will move downward synchronously with the rotating rod 401. During the downward movement, the sliding rod 506 will slide along the inner wall of the third sliding groove 510. Since the upper end of the third sliding groove 510 is inclined, the sliding rod 506 will slide along the inner wall of the second sliding groove 507 at the same time. Then the sliding rod 506 will drive the push plate 505 to slide inside the inner groove 503. At the same time, the third spring 504 will be compressed. After that, the soil produced by the drilling will be on the surface of the spiral leaf 416. Then, the rotation of the spiral leaf 416 can lift the soil upward along the inner wall of the transmission cylinder 15. Then, the soil will enter the inner groove 503 through the connecting port 508, and then in After the drilling is completed, the damping drill mechanism 4 is lifted by the second motor 7. When the drill bit 413 is withdrawn from the borehole, the connection box 501 is lifted along with the rotating rod 401, and then the sliding rod 506 slides along the inclined groove of the third sliding groove 510, thereby driving the push plate 505 to slide and reset along the inner groove 503. At the same time, the previously compressed force of the third spring 504 can provide auxiliary effect for the reset of the push plate 505. During the sliding process, the push plate 505 pushes the soil inside the inner groove 503 into the transmission box 8, and then the soil enters the collection box 10 through the connecting hose 9, thereby completing the drilling. After that, the soil inside the collection box 10 can be cleaned by opening the handle 11;

[0041] After the drilling is completed, when the push plate 505 slides along the inner wall of the inner groove 503, the water pipe 1606 will be driven to move through the mounting block 1609, and then the water pipe 1606 will drive the connecting rod 1603 to move synchronously through the sleeve 1604, and at the same time, the connecting rod 1603 will drive the extrusion ring 1602 to slide on the inner wall of the water storage pipe 1601. Since the water storage pipe 1601 and the connecting pipe 1611 are connected, the water in the water tank 1612 will pass through the connecting pipe 1611. 11 enters the interior of the water storage pipe 1601, and then the squeezing ring 1602 passes over the position of the connecting pipe 1611 and slides. At this time, the squeezing ring 1602 squeezes the water inside the water storage pipe 1601, and then the water pressure squeezes the block 1608 into the interior of the inner cavity 1605, and then the water flows through the inner cavity 1605 and the water guide pipe 1606 into the mounting block 1609, and then is sprayed out through the nozzle 1610, and the inner wall of the inner tank 503 can be sprayed and cleaned;

[0042] As described above, when the drill bit 413 withdraws from the borehole, the slide bar 506 will slide along the inclined groove of the third slide groove 510, thereby driving the push plate 505 to slide and reset along the inner groove 503. During the sliding process, the push plate 505 will push the soil inside the inner groove 503 into the transmission box 8, and then the soil enters the collection box 10 through the connecting hose 9, completing the function of collecting the soil generated by drilling. At the same time, when the drill bit 413 withdraws from the borehole, the soil will not fall into the borehole again, ensuring that the actual depth of the borehole is consistent with the expected depth, thereby improving the work quality.

[0043] After drilling during construction, when the push plate 505 drags the soil inside the inner groove 503, the water flow inside the water storage pipe 1601 is squeezed through the squeezing ring 1602, so that the water flows into the mounting block 1609 through the water pipe 1606, and then is sprayed out through the nozzle 1610, thereby achieving water spray cleaning of the inside of the inner groove 503, which can loosen the soil and make subsequent cleaning work easier.

[0044] Working principle: First, the damping drill mechanism 4 of the output shaft can be driven to rotate at high speed by driving the first motor 6, thereby driving the limit plate 414 on the inner wall of the first slide groove 415 to rotate through the rotating rod 401, and then the limit plate 414 will drive the drill 413 to rotate at high speed through the connecting column 412, and the connecting plate 3 is threadedly connected to the outer wall of the stud 2. Therefore, when the stud 2 rotates, the connecting plate 3 will slide downward along the inner wall of the connecting tube 1, and then drive the first motor 6 to move downward at the same time, and then the first motor 6 will drive the damping drill mechanism 4 to continue to move downward, so as to achieve the effect of drilling;

[0045] The connecting box 501 will move downward synchronously with the rotating rod 401. During the downward movement, the sliding rod 506 will slide along the inner wall of the third sliding groove 510. Since the upper end of the third sliding groove 510 is inclined, the sliding rod 506 will slide along the inner wall of the second sliding groove 507 at the same time. Then the sliding rod 506 will drive the push plate 505 to slide inside the inner groove 503. At the same time, the third spring 504 will be compressed. After that, the soil produced by the drilling will be on the surface of the spiral leaf 416. Then, the rotation of the spiral leaf 416 can lift the soil upward along the inner wall of the transmission cylinder 15. Then, the soil will enter the inner groove 503 through the connecting port 508. After the drilling is completed, the soil will be lifted upward along the inner wall of the transmission cylinder 15 through the second connecting port 508. The motor 7 lifts the damping drill mechanism 4. When the drill bit 413 is withdrawn from the borehole, the connection box 501 is lifted along with the rotating rod 401. Then the sliding rod 506 slides along the inclined groove of the third sliding groove 510, thereby driving the push plate 505 to slide and reset along the inner groove 503. At the same time, the previously compressed force of the third spring 504 can provide auxiliary effect for the reset of the push plate 505. During the sliding process, the push plate 505 pushes the soil inside the inner groove 503 into the transmission box 8. Then the soil enters the collection box 10 through the connecting hose 9, thereby completing the drilling. After that, the soil inside the collection box 10 can be cleaned by opening the handle 11.

[0046] After the drilling is completed, when the push plate 505 slides along the inner wall of the inner groove 503, the water pipe 1606 will be driven to move through the mounting block 1609, and then the water pipe 1606 will drive the connecting rod 1603 to move synchronously through the sleeve 1604, and at the same time, the connecting rod 1603 will drive the extrusion ring 1602 to slide on the inner wall of the water storage pipe 1601. Since the water storage pipe 1601 and the connecting pipe 1611 are connected, the water in the water tank 1612 will pass through the connecting pipe 1611. 11 enters the interior of the water storage pipe 1601, and then the squeezing ring 1602 passes over the position of the connecting pipe 1611 and slides. At this time, the squeezing ring 1602 will squeeze the water inside the water storage pipe 1601, and then the water pressure will squeeze the block 1608 into the interior of the inner cavity 1605, and then the water flow will pass through the inner cavity 1605 and the water pipe 1606 into the mounting block 1609, and then be sprayed out through the nozzle 1610, and the inner wall of the inner tank 503 can be sprayed with water for cleaning.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
