Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a rotary drilling hole protection wall support device. Background Art

[0002] In various construction projects, rotary drilling is a common and critical process, widely used in the construction of structures such as pile foundations. During the rotary drilling process, due to the complex and changeable geological conditions, such as soft soil and the presence of groundwater, the stability of the retaining wall becomes a key factor affecting construction safety and quality. If the retaining wall cannot be effectively supported, it is very likely to collapse, deform, and other problems, which will not only hinder the construction progress, but also cause serious safety accidents, resulting in casualties and property losses. The existing support devices require a lot of manpower and time during the installation process. Construction workers need to perform complex operations in narrow holes, such as adjusting the positions and angles of multiple support components one by one, which not only increases labor intensity but also reduces installation efficiency. In addition, when not in use, the existing support devices often take up a large space and are inconvenient to transport and carry. Since construction projects usually need to be carried out in different sites, equipment needs to be frequently transferred, and the support devices that are difficult to store bring great difficulties to transportation work, increasing transportation costs and construction preparation time.

[0026] The implementation principle of a rotary drilling hole protection wall support device is as follows: when in use, the device is extended into the protection wall of the rotary drilling hole, and then the rotating plate 23 is rotated, the rotating plate 23 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the spur gear 21 to rotate, the spur gear 21 drives the gear ring 20 to rotate, the gear ring 20 drives the bevel gear ring 18 to rotate, the bevel gear ring 18 drives the bevel gear 6 engaged with it to rotate, the bevel gear 6 drives the screw 13 to move toward the outer wall of the support ring 1, the screw 13 drives the connecting seat 2, the folding support plate 18 and the folding support plate 29 to move toward the guard arm through the mounting block, and finally the connecting seat 2, The folding support plate 1 8 and the folding support plate 2 9 are in contact with and squeezed against the guard wall, and then the knobs 11 on the folding support plate 1 8 and the folding support plate 2 9 are respectively turned, so that the knob 11 drives the screw rod 2 10 to rotate, and the screw rod 2 10 drives the connecting plate 13 to move downward, and the connecting plate 13 drives the top of the diagonal support rod 14 to move downward, and then the diagonal support rod 14 is manually rotated to align the bottom end of the diagonal support rod 14 with the support frame 15, so that the bottom end of the diagonal support rod 14 is inserted into the support frame 15, and the slide rod 17 is inserted into the limit groove 16, and finally the diagonal support rod 14 is tilted to a certain angle, thereby completing the alignment of the folding support plate 1 8 and the folding support plate. The support of the second 9 is fixed so that the connecting seat 2, the folding support plate 18 and the folding support plate 29 can stably support the wall. When the device is no longer needed, the knobs 11 on the folding support plate 18 and the folding support plate 29 can be rotated in the opposite direction to make the screw 2 10 drive the connecting plate 13 to move upward, so that the connecting plate 13 drives the diagonal support rod 14 out of the support frame 15. At this time, the folding support plate 18 and the folding support plate 29 can be folded directly inward so that the folding support plate 18 and the folding support plate 29 are folded into the folding groove 1 36 and the folding groove 2 37 respectively, and then the rotating plate 23 is rotated in the opposite direction to The bevel gear 6 can drive the screw rod 3 to move toward the inside of the support ring 1, so that the screw rod 3 drives the connecting seat 2, the folding support plate 1 8 and the folding support plate 2 9 to retract toward the support rod through the mounting block, thereby completing the folding and storage of the support mechanism. Through the above structure, it is convenient for personnel to simultaneously adjust the support mechanism on the support ring 1 to extend or retract outward, thereby improving the installation efficiency of the support device in the guard wall. When the device is not in use, the support mechanism can be folded and stored to reduce the occupied space, thereby facilitating transportation and handling by personnel and facilitating use by personnel.When the connecting seat 2 needs to be disassembled, maintained or replaced, the pull ring 31 can be pulled first, so that the pull ring 31 drives the limit slider 32 to compress the spring 34, so that the pull ring 31 drives the limit bar 30 to disengage from the rod groove 29, and then the snap ring 28 can be rotated at this time, so that the snap ring 28 twists the torsion spring 40, so that the snap ring 28 drives the rod groove 29 to rotate to the positioning rod 25, so that the snap ring 28 no longer limits the positioning rod 25, and then the connecting seat 2 can be directly pulled outward to disengage the positioning rod 25 from the positioning hole 26, thereby completing the disassembly of the connecting seat 2. During installation, the positioning rod 25 is inserted into the positioning hole 26, and then the snap ring 28 is loosened, so that the card is clamped again under the reset force of the torsion spring 40. The locking groove 27 is then released, and the pull ring 31 is then released. At this time, the limiting slider 32 will drive the pull ring 31 to reset under the restoring force of the spring 34, so that the pull ring 31 drives the limiting bar 30 to insert into the rod groove 29, and the clamping ring 28 is fixed in position, thereby completing the installation of the connecting seat 2. The above structure facilitates the disassembly and assembly of the connecting seat 2, thereby facilitating the maintenance or replacement of the connecting seat 2, folding support plate 18, and folding support plate, ensuring the normal supporting strength of the connecting seat 2, folding support plate 18, and folding support plate on the guard wall. The connecting seat 2, folding support plate 18, and folding support plate of different curvatures can be replaced to adapt to guard walls of different specifications, reducing the limitations of the device.
