[0001] The utility model relates to the technical field of compaction pile foundation hole forming, in particular to a drilling device for compaction pile foundation hole forming. Background Art

[0002] Compaction piles are formed by pressing or driving a steel pipe with a pipe plug, valve or cone head into the soil to form a hole, compacting the soil layer, and then adding fillers such as ash, sand and gravel into the hole. The main methods for forming holes in compaction pile foundations include the impact hole method, which uses an impact machine to repeatedly impact the soil layer to form a hole, and the sinking pipe hole method, which uses a pile driver to drive a pointed pile pipe into the soil layer to the designed bottom elevation, and then pull out the pile pipe to form a hole.

[0003] However, when drilling holes for compacted pile foundations, construction workers need to position the drilling equipment frame by setting up a theodolite, and the frame needs to be repositioned every time it is moved or the height of the frame is adjusted, resulting in large errors, low efficiency and high labor intensity. Utility Model Content

[0004] In order to solve the problem that when drilling holes for compacted pile foundations, construction workers need to position the drilling equipment frame by setting up a theodolite, and the frame needs to be repositioned every time it is moved or the height of the frame is adjusted; the purpose of the utility model is to provide a drilling device for compacted pile foundation holes.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: A drilling device for compacting pile foundation holes, comprising a mounting plate, wherein two symmetrically distributed mounting brackets are fixedly installed on the lower part of the mounting plate, a rotating ball is provided in the middle of the two mounting brackets, a first rotating shaft is fixedly installed in the middle of the two rotating balls, a first limiting bracket is rotatably installed on one side of the lower part of the two mounting brackets, a second limiting bracket is rotatably installed on the other side of the lower part of the two mounting brackets, a sliding rod is provided at the lower part of the two rotating balls, the lower parts of the two sliding rods are slidably clamped in the middle part of the first limiting bracket and the second limiting bracket, a laser lamp is fixedly installed on the bottom end of the two sliding rods, a first bevel gear is fixedly installed on one side of the two second limiting brackets, a third rotating shaft is rotatably installed on one side of the mounting plate, a second bevel gear is fixedly installed on both ends of the third rotating shaft, and the two second bevel gears are meshed with the first bevel gear, a driving assembly is provided on one side of one of the mounting brackets, and the bottom end of the mounting plate is fixedly mounted on a frame.

[0006] Preferably, a screw is rotatably installed on one side of the lower part of the mounting plate, and both sides of the screw are provided with positive and negative threads. The lower part of the mounting plate is provided with two groups of symmetrically distributed protective covers, and one side of the two groups of protective covers are threadedly installed on the outer surface of the screw. A first motor is provided on one side of the screw, and one end of the screw is fixedly installed on the driving end of the first motor.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. This application can position the frame by adjusting the angle of the laser light so that its intersection is aligned with the compacted pile hole. When the frame is moved in a single direction or when adjusting its height, the frame can be positioned by simply adjusting the angle of the laser light, eliminating the need for workers to set up the theodolite again for positioning, thereby speeding up work efficiency and reducing errors. 2.

The two ends of the second limiting frame 43 are fixedly mounted with a first bevel gear 44, and a third rotating shaft 48 is rotatably mounted on one side of the mounting plate 2. Second bevel gears 47 are fixedly mounted on both ends of the third rotating shaft 48. The two second bevel gears 47 are meshed with the first bevel gear 44. A driving assembly is provided on one side of one of the mounting frames 4, and the bottom end of the mounting plate 2 is fixedly mounted on the frame 1.

[0019] A screw rod 32 is rotatably mounted on one side of the lower portion of the mounting plate 2, and both sides of the screw rod 32 are provided with forward and reverse threads. Two groups of symmetrically distributed protective covers 3 are provided on the lower portion of the mounting plate 2, and one side of the two groups of protective covers 3 are threadedly mounted on the outer surface of the screw rod 32. A first motor 31 is provided on one side of the screw rod 32, and one end of the screw rod 32 is fixedly mounted on the driving end of the first motor 31.

[0020] The driving assembly includes a second motor 412, which is fixedly mounted on one side of the lower portion of the mounting plate 2. One side of a first rotating shaft 411 is fixedly mounted on the driving end of the second motor 412. By setting the second motor 412, the first rotating shaft 411 can be driven to rotate under the drive of the second motor 412, that is, the rotating ball 41 can be driven to rotate.

[0021] The second rotating shafts 413 are fixedly mounted on opposite sides of the two first rotating shafts 411 . By providing the second rotating shafts 413 , the two rotating balls 41 can be driven by the second motor 412 to rotate simultaneously.

[0022] A fixing plate 311 is fixedly mounted on one side of the lower portion of the mounting plate 2 , and the bottom end of the first motor 31 is fixedly mounted on the top end of the fixing plate 311 . By providing the fixing plate 311 , the first motor 31 can be fixedly mounted.

[0023] The lower parts of the two rotating balls 41 are each provided with a slide groove 451, and the upper parts of the two sliding rods 45 are both slidably clamped inside the slide groove 451. By setting the slide groove 451, the sliding rod 45 can be driven by the second motor 412 and limited by the slide groove 451 to slide in the middle of the first limit frame 42 following the rotation of the rotating ball 41.

[0024] A limiting rod 33 is fixedly installed on one side of the lower part of the mounting plate 2, and one side of the two sets of protective covers 3 are slidably clamped on the outer surface of the limiting rod 33. By setting the limiting rod 33, when the protective cover 3 is driven to move by the screw rod 32, it is more stable under the limit of the limiting rod 33.

[0025] A third motor 49 is fixedly mounted on one side of the middle portion of the mounting plate 2, and a worm 491 is provided on one side of the third motor 49. One end of the worm 491 is fixedly mounted on the driving end of the third motor 49, and the other end of the worm 491 is rotatably mounted on one side of the middle portion of the mounting plate 2. A worm gear 492 is fixedly mounted on the middle portion of the third rotating shaft 48, and the worm gear 492 and the worm 491 are meshed and connected with each other. By arranging the worm gear 492 and the worm 491, the structure has a self-locking function, which makes it more stable when adjusting the angle of the laser lamp 46, thereby ensuring that the angle of the laser lamp 46 does not change during drilling.

[0026] Working principle: In actual use, the staff first uses the theodolite to position the x-axis of its frame 1, and drives the first rotating shaft 411 to rotate through the drive of the second motor 412. Under the transmission of the second rotating shaft 413, the two rotating balls 41 rotate at the same time, that is, the sliding rod 45 is driven to slide in the middle of the first limiting frame 42, so that it maintains the same straight line with the x-axis of the frame 1 positioned by the theodolite. At this time, the worm 491 is driven by the drive of the third motor 49, that is, the worm gear 492 is driven to rotate, so that the third rotating shaft 48 rotates, so that under the mutual cooperation of the second bevel gear 47 and the first bevel gear 44, the second limiting frame 43 is driven to move relative to each other, thereby converging the laser end points of the two laser lamps 46, thereby positioning the drilling of the compaction pile. Since it is necessary to adjust the different heights of the frame 1 when drilling compaction piles of different depths, it is only necessary to drive the third motor 49 to converge the light of the laser lamp 46 on the same axial direction to position the drilling of the compaction pile.

[0027] When the laser lamp 46 is not in use, the screw 32 is driven by the first motor 31 to rotate, so that the two sets of protection covers 3 are evenly close to the middle of the laser lamp 46, thereby protecting the laser lamp 46.

[0028] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
