The guide device is used to guide the pile driver drill rod when drilling the pile hole. The guide device includes a guide support base 1, and the guide support base 1 is provided with a passage hole for the drill rod to pass through. The top of the guide support base 1 is connected to a through-set protective sleeve 11, and the through-core cavity of the protective sleeve 11 is coaxially arranged with the passage hole for the pile driver drill rod to pass through. The hollow cavity of the protective sleeve 11 is provided with a movable adjustment guide mechanism for guiding and limiting the pile driver drill rod. The guide device is hoisted and moved to the position where the pile foundation hole is placed, and the channel hole of the guide support cap 1 is adjusted to align with the position where the pile foundation hole is placed by passing the anchor rod connecting holes opened around the guide support cap 1 with anchor rods, and then the guide support cap 1 is anchored to the foundation soil with anchor rods, and the bottom end of the drill rod of the pile driver passes through the guide device, and the initial verticality of the drill rod of the pile driver is adjusted, and then the pile driver is controlled to drive the drill rod to perform the drilling construction of the pile foundation hole, and the active adjustment guide mechanism set by the guide device plays a movable guiding effect on the passed pile driver drill rod, so that the pile driver drill rod can smoothly perform the drilling construction of the pile foundation hole; at the same time, the active adjustment guide mechanism includes active structures symmetrically arranged on both sides of the channel hole; when the pile driver drill rod is tilted during the drilling process, the two active structures are appropriately adjusted to properly return the "center" of the pile driver drill rod passing through the two active structures, so as to achieve a certain correction adjustment, thereby ensuring the verticality requirement of the hole drilled by the drill rod.

[0053] In the embodiment, the end of the protective sleeve 11 away from the guide support pedestal 1 is connected and fixed to the bottom end of the connecting pedestal 12, and the connecting pedestal 12 is provided with a movable guide hole coaxially arranged with the channel hole provided in the guide support pedestal 1; the bottom end of the connecting pedestal 12 is provided with a movable guide cylinder 121 for the pile driver drill rod to pass through and arranged through the center, the top end of the movable guide cylinder 121 is connected and fixed to the bottom end of the connecting pedestal 12, and the through cavity of the movable guide cylinder 121 is coaxially arranged with the channel hole provided in the guide support pedestal 1 for the pile driver drill rod to pass through; the movable guide cylinder 121 is arranged in the protective sleeve 11. The movable guide cylinder 121 not only can realize the connection between the guide support pedestal 1 and the connecting pedestal 12, but also can realize the protection of the movable adjustment guide mechanism provided in the protective sleeve 11, reduce the soil entering during the drilling process, and affect the movable adjustment guide mechanism, thereby affecting the movable guide and the purpose of fine adjustment of the pile driver drill rod. It should be noted here that a lifting connection piece is pre-embedded at the top of the connecting base 12 for facilitating lifting by a lifting machine, thereby facilitating the movement and transportation of the guide device.

[0054] Example 2

[0055] Based on Example 1, the two movable structures of the arrangement include a first movable rotating stick 3 and a second movable rotating stick 4; the first movable rotating stick 3 is rotatably connected to the first rotating shaft, the top end of the first rotating shaft is rotatably connected to one end of the first top movable hinged rod a31, and the bottom end of the first rotating shaft is rotatably connected to one end of the first bottom movable hinged rod b32; the second movable rotating stick 4 is rotatably connected to the second rotating shaft, the top end of the second rotating shaft is rotatably connected to one end of the second top movable hinged rod a41, and the bottom end of the second rotating shaft is rotatably connected to one end of the second bottom movable hinged rod b42; the first top movable hinged rod a31 is away from one end of the first movable rotating stick 3 The end and the second top movable hinged rod a41 away from the second movable rotating stick 4 are both rotatably connected to one end of the vertical connecting shaft; the end of the first bottom movable hinged rod b32 away from the first movable rotating stick 3 and the end of the second bottom movable hinged rod b42 away from the second movable rotating stick 4 are both rotatably connected to the other side of the vertical connecting shaft away from the first top movable hinged rod a31; and, the end of the vertical connecting shaft away from the first top movable hinged rod a31 is rotatably connected to the guide support base 1 through a connecting block; a movable support structure for movably supporting and guiding the pile driver drill rod is also movably arranged between the first movable rotating stick 3 and the second movable rotating stick 4. The pile driver drill rod passes through the movable guide hole provided in the connection pedestal 12, and passes through the movable guide cylinder 121 at the bottom of the connection pedestal 12, and passes through the movable adjustment guide mechanism provided, and passes through the movable guide of the movable adjustment guide mechanism, that is, between the first movable rotating rod 3 and the second movable rotating rod 4 of two movable structures which are symmetrically provided and adjusted to the initial position; the first movable rotating rod 3 and the second movable rotating rod 4 provided can both be provided with "rotatable and movable" settings, and the pile driver drill rod passing through can be movably guided, so that the pile driver drill rod can smoothly pass through the channel hole provided in the guide support pedestal 1, and perform drilling construction on the pile foundation hole. If the pile driver drill rod tilts during the drilling process, the pile driver drill rod can be "returned and corrected" by controlling the two movable structures at this time, so as to ensure the verticality requirement of the pile foundation hole to be drilled.

[0056] Further, in the embodiment, the movable support structure includes a movable guide support roller 5, which is rotatably connected to the movable guide shaft; the top of the movable guide shaft is rotatably connected to the first guide top connecting rod a51 and the second guide top connecting rod a52; the end of the first guide top connecting rod a51 away from the movable guide support roller 5 is rotatably connected to the middle of the bottom end of the first top movable hinged rod a31 through a pin shaft; the end of the second guide top connecting rod a52 away from the movable guide support roller 5 is rotatably connected to the middle of the bottom end of the second top movable hinged rod a41 through a pin shaft. In addition, the bottom of the movable guide shaft is rotatably connected to the first guide bottom connecting rod b53 and the second guide bottom connecting rod b54; the end of the first guide bottom connecting rod b53 away from the movable guide support roller 5 is rotatably connected to the middle of the bottom end of the first bottom movable hinged rod b32 through a pin shaft; the end of the second guide bottom connecting rod b54 away from the movable guide support roller 5 is rotatably connected to the middle of the bottom end of the second bottom movable hinged rod b42 through a pin shaft. The movable guide support roller 5 is movably arranged between the first movable rotating rod 3 and the second movable rotating rod 4, and can provide a certain movable support limit for the pile driver drill rod passing through, thereby ensuring that the pile driver drill rod can be in a "flexible movable adjustment" while passing through the two movable structures, so that the pile driver drill rod can be moved in the adjusted center of the movable structure, even when the pile driver drill rod is initially drilled, it is in the adjusted initial vertical position for drilling construction. The axial displacement of the first movable rotating stick 3 and the second movable rotating stick 4 on the outer side of the movable guiding support roller 5 is adjusted, and the axial displacement of the first movable rotating stick 3 and the second movable rotating stick 4 on the outer side of the movable guiding support roller 5 is adjusted. The axial displacement of the second movable rotating stick 4 on the outer side of the movable guiding support roller 5 is adjusted, and the axial displacement of ...

[0057] Example 3

[0058] In order to achieve convenient control and adjustment of the two movable structures, a through-type hydraulic cylinder 2 (an existing through-type hydraulic rod with a cylinder body) is connected to the movable guide cylinder 121; the end of the movable guide cylinder 121 away from the connection base 12 passes through the through-type cavity of the through-type hydraulic cylinder 2, and the outer wall of the movable guide cylinder 121 is fixedly connected to the through-type cavity of the through-type hydraulic cylinder 2, and the output rod body of the through-type hydraulic cylinder 2 can be telescopically moved along the outer wall of the movable guide cylinder 121. The end of the output rod body of the through-type hydraulic cylinder 2 away from the connection base 12 is connected to a through-type connecting disc 21; the connecting disc 21 is movably arranged on the movable guide cylinder 121, and under the telescopic movement of the output rod body of the through-type hydraulic cylinder 2, the connecting disc 21 is driven to telescopically move along the movable guide cylinder 121; the end surface of the connecting disc 21 away from the connection base 12 is respectively connected to a first movable connecting structure hinged to the first top movable hinged rod a31 and a second movable connecting structure hinged to the second top movable hinged rod a41.

[0059] Furthermore, the first movable connection structure includes a first movable connection rod 22; one end of the first movable connection rod 22 is rotatably hinged to the bottom end surface of the connecting disc 21 through a hinge seat, and the other end of the first movable connection rod 22 is rotatably hinged to the first top movable hinge rod a31 near the first movable rotating rod 3 through a hinge seat. The second movable connection structure includes a second movable connection rod 23; one end of the second movable connection rod 23 is rotatably hinged to the bottom end surface of the connecting disc 21 through a hinge seat, and the other end of the second movable connection rod 23 is rotatably hinged to the second top movable hinge rod a41 near the second movable rotating rod 4 through a hinge seat.

[0060] At the same time, a first supporting movable rod 221 which can slide along the first movable connecting rod 22 is hinged at one end of the first movable connecting rod 22 close to the movable guide cylinder 121 through a sliding hinge seat, and the other end of the first supporting movable rod 221 is rotatably connected to a first supporting roller 222 for movably supporting the pile driver drill rod through a rotating shaft; a first supporting movable rod 221 which can slide along the first supporting movable rod 221 and is tilted is hinged at one end of the first supporting movable rod 221 close to the movable guide cylinder 121 through a sliding hinge seat, and the other end of the first supporting hinge rod 223 is hinged to an end surface of the movable guide cylinder 121 close to the guide support base 1 through a hinge seat. One end of the second movable connecting rod 23 close to the movable guide cylinder 121 is hinged to a second supporting movable rod 231 which can slide along the second movable connecting rod 23 through a sliding hinge seat, and the other end of the second supporting movable rod 231 is rotatably connected to a second supporting roller 232 for movably supporting the pile driver drill rod through a rotating shaft; one end of the second supporting movable rod 231 close to the movable guide cylinder 121 is hinged to a second supporting hinged rod 233 which can slide along the second supporting movable rod 231 and is tilted through a sliding hinge seat, and the other end of the second supporting hinged rod 233 is hinged to an end surface of the movable guide cylinder 121 close to the guide support base 1 through a hinge seat.

[0061] In the embodiment, the movable adjustment guide mechanism and its corresponding connection structure are both arranged in the protective sleeve 11, and the protective sleeve 11 protects the structure inside, reduces the amount of soil outside entering inside, and avoids affecting the "activity" of each structure. When the pile driver drill rod is tilted during the drilling process (the verticality exceeds the design allowable range); at this time, the output end rod body of the through-core hydraulic cylinder 2 is controlled and the output end rod body is movably sleeved on the protective sleeve 11, and the output end rod body is driven to telescope and move along the outer wall of the protective sleeve 11 through the through-core hydraulic cylinder 2; due to the telescoping of the output end rod body of the through-core hydraulic cylinder 2, the connecting disc 21 connected to the end of the output end rod body and movably sleeved on the protective sleeve 11 is driven to telescope and move along the surface of the protective sleeve 11, and the movement of the connecting disc 21 drives the first movable connecting rod 22 and the second movable connecting rod 23, which are respectively "rotatably" hinged on the other end surface of the connecting disc 21, to move, and then the first top movable connecting rod 22 drives the first movable connecting rod 22 to move The hinged rod a31 moves, and the second movable connecting rod 23 drives the second top movable hinged rod a41 to move; since the first movable connecting rod 22 and the second movable connecting rod 23 are relatively inclined, under the relative driving and moving action of the connecting disc 21, the first movable connecting rod 22 and the second movable connecting rod 23 move relative to each other away from the end of the connecting disc 21, thereby realizing the relative adjustment of the relative distance between the first movable rotating rod 3 and the second movable rotating rod 4, so as to adapt to the active guiding of pile driver drill rods of different diameters, and under the active limiting support and guiding action of the active guiding support roller 5, it can adapt to and guide pile driver drill rods of different diameters, and enable the pile driver drill rod to smoothly pass through the active adjustment guiding mechanism to perform drilling construction on the pile foundation hole. Furthermore, when the first movable rotating rod 3 and the second movable rotating rod 4 are adjusted to adapt to pile driver drill rods of different diameters, the first movable connecting rod 22 drives the first supporting movable rod 221 under the movable hinge action of the first supporting hinge rod 223, so that the first supporting roller 222 rotatably connected to the end of the first supporting movable rod 221 "micro-moves" a certain distance relative to the pile driver drill rod, and the second movable connecting rod 23 drives the second supporting movable rod 231 under the movable hinge action of the second supporting hinge rod 233, so that the second supporting roller 232 rotatably connected to the end of the second supporting movable rod 231 "micro-moves" a certain distance relative to the pile driver drill rod; thereby, the "four supporting rollers" movably arranged between the movable guide cylinder 121 and the guide support base 1 can move synchronously, that is, the distance between the pile driver drill rods is relatively moved, and the support and guide limit of different pile driver drill rods is realized.Moreover, by controlling the extension and retraction of the through-core hydraulic cylinder 2, the "four supporting rollers" and the "four movable rotating rods" can be driven to move synchronously; and then, the relative positions of the "four supporting rollers" and the "four movable rotating rods" can be adjusted according to actual needs to achieve "deviation correction and correction" (within the verticality deviation range allowed by the design) of the inclined pile driver drill rod, thereby ensuring the verticality requirement of the pile driver during the pile driver drill rod construction.
