Description

Technical Field

[0001] The invention belongs to the technical field of engineering lines, in particular to a transmission line pole foundation pile rotary drilling device. Background Art

[0002] Rotary bored piles refer to bored piles formed by the construction of a rotary drilling rig. During construction, the rotary drilling rig first uses a barrel-type drill bit with a valve at the bottom to rotate and crush the rock and soil, and directly loads the crushed rock and soil into the drill bucket. The drill rig's lifting device and telescopic drill rod then lift the drill bit out of the inclined soil outside the bored pile. This reciprocating cycle continuously extracts and unloads soil until the designed depth is reached. Rotary bored piles have been widely used in highways, railways, bridges, large buildings and other fields.

[0003] A patent with announcement number CN 105822230 A discloses a rotary drilling auxiliary device for a rotary drilling rig, including a supporting leg, a cylinder, and a base. The front part of the cylinder is provided with a piston rod, the front end of the piston rod is movably riveted to the front end of the supporting leg, and the rear part of the cylinder is separated from the rear end of the supporting leg; the front end of the supporting leg or the front end of the piston rod of the cylinder is connected to the base. The present invention also provides a rotary drilling rig. The rotary drilling auxiliary device overcomes the defects of the prior art such as short service life, low working efficiency and high cost of the drill rod, and has the advantages of simple structure and easy operation.

[0004] In the current existing technology, when the foundation pile is rotary excavated, when the underground is in a soft silt layer, the silt layer is easily deformed when the drill bit is excavating. The deformed silt layer will accumulate and adhere to the surface of the drill bit due to its own gravity, so that when the drill bit continues to rotate downward, the soft silt cannot be effectively discharged. Under the extraction of some mud pumps, after the silt adhering to the surface of the drill bit is cleaned up, the soft silt surface around the drill hole has no supporting force, and will accumulate on the surface of the drill bit again under its own gravity, so that the diameter of the drill hole will become larger and larger, and the depth of the hole cannot be effectively and continuously increased. In addition, the hole wall around the soft soil layer is relatively soft, so that the drill rod cannot effectively support the surface of the drill rod while drilling, which can easily cause the drill rod to shake due to deviation in the drilling angle.

[0005] To this end, the present invention provides a transmission line pole foundation pile rotary drilling device. Summary of the invention

The plate and the semicircular bonding plate are transmitted to the surface of the supporting column, which causes the supporting column to shake irregularly, and at the same time, the elastic wire on the inner wall of the semicircular bonding plate performs secondary elastic buffering on the transmission rod 1 under the large swing, and the elastic wire is used to gradually elastically squeeze the transmission rod 1 under the large swing, and then elastically restore the transmission rod 1, so that the semicircular bonding plate and the arc bonding plate can be used to limit the rotation position of the transmission rod 1, and the vibration and swing of the transmission rod 1 can be elastically buffered and restored without causing stagnation or friction to the rotation of the transmission rod 1.

[0030] With the help of the crane, the lap plate 12 is moved to the position where a hole needs to be drilled, and the hydraulic rod 123 is used to press down the auxiliary pressing rod 124, so that the transmission rod 127 and the drill bit 128 on one end of the auxiliary pressing rod 124 continuously press down on the inner wall of the foundation layer 11, and at the same time, the motor 126 is used to rotate the transmission rod 127 to overturn and excavate the soil inside the foundation layer 11. When the drill bit 128 is completely immersed in the foundation layer 11, the swing arm 141 is used to swing on the outer surface of the limit rod 14, and the semicircular bonding plates 142 and the arc bonding plates 144 on one end of the two sets of swing arms 141 are closed and wrapped around the outer surface of the transmission rod 127, so as to achieve the effect of limiting the position of the transmission rod 127 to a relatively narrow space by using the semicircular bonding plates 142 and the arc bonding plates 144.

[0031] like Figures 1 to 8As shown, a limiting plate 147 is fixedly connected to the inner wall of the limiting sleeve 146, a transmission rod 148 is fixedly connected to the inner wall of the limiting plate 147, a sliding roller 149 which is movably overlapped on the outer surface of the limiting plate 147 is arranged on the outer surface of the transmission rod 148, a hydraulic rod 123 which is arranged on the outer surface of the support column 13 is fixedly installed on the top surface of the overlap plate 12, the output end of the hydraulic rod 123 passes through the support column 13 and an auxiliary pressing rod 124 is fixedly connected to one end, and the outer surface of the auxiliary pressing rod 124 is movably overlapped on the outer edge of the support column 13, a protective sleeve 125 is fixedly connected to one end of the auxiliary pressing rod 124, and the protective sleeve A motor 126 is provided on the inner wall surface of the shell 125, and a transmission rod 127 is fixedly connected to the output end of the motor 126, and a drill bit 128 is fixedly installed on the outer surface of the transmission rod 127. A support frame 121 is fixedly connected to the top surface of the lap plate 12, and a limiting ring 122 that is movably sleeved on the outer surface of the hydraulic rod 123 is fixedly connected to one end of the support frame 121. A limiting slider 131 is slidably sleeved on the outer surface of the support column 13, and a lap plate 132 that is movably sleeved on the outer surface of the transmission rod 127 is fixedly connected to the outer surface of the limiting slider 131, and the bottom surface of the protective shell 125 is fixedly connected to the top surface of the lap plate 132.

[0032] At the same time, the sliding roller 149 on the inner wall of the arc-shaped bonding plate 144 is bonded to the surface of the transmission rod 127. When the motor 126 rotates the transmission rod 127, the transmission rod 127 is continuously rotated and slid on the surface of the sliding roller 149. When the transmission rod 127 is stirred inside the soft soil layer, it vibrates, and the transmission rod 127 squeezes the surface of the limiting shell 146. At this time, the shockproof silicone layer 145 on the outer surface of the limiting shell 146 is used to buffer the vibration of the transmission rod 127, so as to avoid the impact force generated by the vibration of the transmission rod 127 being unable to be effectively buffered, and directly passing through the arc-shaped bonding plate 144 and the semicircular bonding plate 1 42 is transmitted to the surface of the support column 13, which causes the support column 13 to shake irregularly, and at the same time, the elastic wire 143 on the inner wall of the semicircular bonding plate 142 cooperates with the elastic wire 143 on the inner wall of the transmission rod 127 under the large-scale swing to perform secondary elastic buffering, and at the same time, the elastic wire 143 is used to gradually elastically squeeze the transmission rod 127 under the large-scale swing, and then elastically restore the transmission rod 127, so that the semicircular bonding plate 142 and the arc-shaped bonding plate 144 can be used to limit the rotation position of the transmission rod 127, and the vibration and swing of the transmission rod 127 can also be elastically buffered and restored, and the self-rotation of the transmission rod 127 will not cause stagnation or friction.

[0033] like Figures 1 to 4 and Figure 8As shown, a water pump c3 is fixedly connected to the bottom surface of the overlapping plate 132, and a water suction pipe c4 is fixedly connected to the output end of the water pump c3, a feeder c1 is fixedly connected to the top surface of the overlapping plate 12, a liquid guide pipe c2 is fixedly connected to the output end of the feeder c1, and one end of the liquid guide pipe c2 and the water suction pipe c4 extends to the outer edge position of the transmission rod 127, a discharge hole a1 is opened on the top surface of the drill bit 128 and located on the surrounding edge positions, a positioning rod a2 is provided on the surface of the drill bit 128, and a overlapping plate a3 movably sleeved on the inner wall surface of the drill bit 128 is fixedly connected to one end of the positioning rod a2, a feed hole a4 is opened on the bottom surface of the overlapping plate a3, and a crushing claw a5 is provided on the bottom surface of the overlapping plate a3 and located on one side edge position of the feed hole a4.

[0034] When the transmission rod 127 drives the drill bit 128 to rotate continuously inside the foundation layer 11, the soft soil layer will adhere to the surface of the drill bit 128. At this time, the feeder c1 is used to inject the polyurethane soil solidifier into the interior of the liquid guide tube c2, and the drill bit 128 is used to continuously stir the soft soil layer, so that the polyurethane soil solidifier and the soft soil layer are fully integrated together, making the soft soil gradually sticky, greatly improving the strength of the silt soil body, and greatly preventing the surrounding soft soil from re-accumulating on the surface of the drill bit 128 under its own gravity. The sticky soft soil can be shaped under the rotation and extrusion of the drill bit 128, thereby forming a relatively complete and downward vertical vertical hole inside the foundation layer 11.

[0035] Working principle: cooperate with the crane to move the lap plate 12 to the position where the hole needs to be drilled, cooperate with the hydraulic rod 123 to press down the auxiliary pressing rod 124, so that the transmission rod 127 and the drill bit 128 on one end of the auxiliary pressing rod 124 continuously press down on the inner wall of the foundation layer 11, and cooperate with the motor 126 to rotate the transmission rod 127 to overturn and excavate the soil inside the foundation layer 11. When the drill bit 128 is completely immersed in the foundation layer 11, cooperate with the swing arm 141 to swing on the outer surface of the limit rod 14, and close and wrap the semicircular bonding plate 142 and the arc bonding plate 144 on one end of the two sets of swing arms 141 on the outer surface of the transmission rod 127, so as to achieve the purpose of using the semicircular bonding plate 142 and the arc bonding plate 14 4 has the effect of limiting the position of the transmission rod 127 in a relatively narrow space; at the same time, the sliding roller 149 on the inner wall of the arc-shaped bonding plate 144 is bonded to the surface of the transmission rod 127. When the motor 126 rotates the transmission rod 127, the transmission rod 127 is continuously rotated and slid on the surface of the sliding roller 149. When the transmission rod 127 is stirred inside the soft soil layer, it vibrates, and the transmission rod 127 squeezes the surface of the limiting casing 146. At this time, the shockproof silicone layer 145 on the outer surface of the limiting casing 146 is used to buffer the vibration of the transmission rod 127, so as to avoid that the impact force generated by the vibration of the transmission rod 127 cannot be effectively buffered and will directly pass through the arc-shaped bonding plate 14 4. The semicircular bonding plate 142 is transmitted to the surface of the support column 13, which causes the support column 13 to shake irregularly. At the same time, the elastic wire 143 on the inner wall of the semicircular bonding plate 142 is used to perform secondary elastic buffering on the transmission rod 127 under large-scale swinging. At the same time, the elastic wire 143 is used to gradually elastically squeeze the transmission rod 127 under large-scale swinging, and then the transmission rod 127 is elastically restored. The semicircular bonding plate 142 and the arc-shaped bonding plate 144 can be used to limit the rotation position of the transmission rod 127, and the vibration and swing of the transmission rod 127 can be elastically buffered and restored, and the self-rotation of the transmission rod 127 will not be stagnant or cause friction. When the transmission rod 127 drives As the drill bit 128 continuously rotates inside the foundation layer 11, the soft soil layer will adhere to the surface of the drill bit 128. At this time, the feeder c1 is used to inject the polyurethane soil solidifier into the interior of the liquid guide tube c2, and the drill bit 128 is used to continuously stir the soft soil layer, so that the polyurethane soil solidifier and the soft soil layer are fully integrated together, making the soft soil gradually sticky, greatly improving the strength of the silt soil body, and greatly preventing the surrounding soft soil from re-accumulating on the surface of the drill bit 128 under its own gravity. The sticky soft soil can be shaped under the rotation and extrusion of the drill bit 128, thereby forming a relatively complete and downward vertical vertical hole inside the foundation layer 11.
