Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pile hole protection tools, in particular to a hole opening protection cover. Background Art
[0002] During construction, pile holes need to be drilled at the construction site first, and then the pile foundation is poured; after the pile holes are drilled, sleeves need to be lowered. Since many pile holes need to be drilled, construction workers cannot complete the pouring at one time during construction. Therefore, when construction workers have not poured the pile holes, the openings of the pile holes need to be covered to prevent people from falling into the pile holes; common protective measures currently include temporary blocking with discarded woven bags, or temporary covering with templates. Since the woven bags and templates only cover the sleeve openings of the pile holes, the woven bags and templates have poor fixation and are easily moved or damaged during construction; and in different constructions, the sizes of the pile holes are different, and the sizes of the woven bags and templates are mostly fixed, which cannot adapt to pile holes of different diameters. Woven bags and templates of different sizes need to be replaced, increasing construction costs. Summary of the invention
[0003] The present invention provides an orifice protection cover, which can overcome certain or some defects of the prior art.
[0004] According to the present invention, an orifice protective cover includes: a protective cover body, the protective cover body includes a circular cover plate; a circular mounting groove is provided at the center of the bottom wall of the cover plate, and a plurality of arc grooves distributed circumferentially along the mounting groove; the arc groove extends inward from the outer edge of the cover plate and interferes with the mounting groove; a sliding plate is provided in the arc groove, a limiting column arranged perpendicular to the sliding plate is provided at the sliding plate, and a rotating mechanism is provided in the mounting groove, and the rotating mechanism is used to push the sliding plate to slide along the arc groove.
[0005] When the construction personnel use the cover plate, they need to twist the rotating disk, and the rotation of the rotating disk drives the gear to rotate, and the rotation of the gear drives the multiple sliding plates to slide along the arc groove. When the multiple sliding plates move, the sliding plates bring the limiting columns to shrink toward the center of the cover plate, or spread toward the outside of the center of the cover plate; when the construction personnel need to cover the pile hole opening with the cover plate, they only need to cover the pile hole opening with the cover plate first, so that the limiting columns under the cover plate extend into the pile hole, and then twist the rotating disk to make the multiple limiting columns spread toward the outside of the center of the cover plate and abut against the side wall of the pile hole, thereby fixing the cover plate to prevent the cover plate from being moved or damaged during construction; when the construction personnel need to remove the cover plate from the pile hole opening, they only need to twist the rotating disk in the opposite direction to make the limiting columns shrink toward the center of the cover plate, so that the squeezing of the side wall of the pile hole by the limiting columns can be released, and then the cover plate can be lifted upward to open the pile hole; Since the limiting column can be changed to different positions under the cover plate, the cover plate can cover and be fixed on pile holes of different sizes.
[0006] Preferably, a groove arranged along the length direction of the arc groove is provided at the side wall of the arc groove away from the mounting groove, and a limit plate extending into the groove is provided at the side wall of the sliding plate; a tooth groove is provided along the length direction of the sliding plate at one end of the sliding plate away from the limit plate; The rotating mechanism includes a gear arranged in the installation groove and meshing with the tooth groove on the sliding plate; a first through hole passing through the cover plate is provided at the center of the bottom wall of the installation groove, and a rotating column passing through the first through hole is provided at the gear; a rotating disk is provided at the end of the rotating column away from the gear.
[0007] Through the present invention, the construction workers rotate the rotating disk to drive the gear to rotate, and the gear rotation drives the sliding plate and the limit posts on the sliding plate to move, so that the multiple limit posts can spread outward and shrink inward along the center of the cover plate, thereby changing the spacing between the limit posts, so that the cover plate can adapt to pile holes of different sizes; When the sliding plate slides along the arc groove, the limiting plate on the sliding plate slides along the groove, and the groove prevents the sliding plate from leaving the arc groove, while also improving the stability of the sliding plate when moving in the arc groove.
[0008] Preferably, a plurality of first limit grooves distributed along the circumference of the first through hole are provided on the top wall of the cover plate, and a second limit groove corresponding to the limit groove is provided on the bottom wall of the rotating disk; a limit block is provided in the second limit groove, and a spring for pushing the limit block into the first limit groove; an arc-shaped surface is provided at the end of the limit block away from the spring.
[0009] With the present invention, when the rotating disk is rotated by the construction personnel, the rotating disk moves with the limit block. During this process, the side wall of the limit groove squeezes the arc surface on the limit block, thereby pushing the limit block to squeeze the spring and retract into the second limit groove until the limit block moves to the top of the adjacent limit groove under the drive of the rotating disk and is pushed into the limit groove again by the spring; when the construction personnel do not twist the rotating disk, the limit block will extend into the limit groove under the action of the spring, thereby preventing the rotating disk from loosening, causing the limit column to squeeze the side wall of the pile hole to loosen, resulting in unstable fixation of the cover plate.
[0010] Preferably, a mounting ring is sleeved on the outer side of the cover plate, and a clamping block extending into the arc-shaped groove is provided on the inner side wall of the mounting ring; a plurality of second through holes distributed along the circumference of the mounting ring are provided on the mounting ring, and a first threaded hole corresponding to the second through holes is provided on the outer side wall of the cover plate; a bolt is provided at the first threaded hole that passes through the second through hole and extends into the first threaded hole.
[0011] According to the present invention, when installing the sliding plate, the installer first removes the mounting ring from the cover plate, then inserts the sliding plate into the arc groove, and then inserts the clamping block on the inner wall of the mounting ring into the arc groove, so as to facilitate pre-fixing of the mounting ring. After the mounting ring is pre-fixed, the installer connects the cover plate to the mounting ring by passing the bolt through the second through hole and screwing it into the first threaded hole.
[0012] Preferably, a threaded column is provided at the top of the rotating column, and a second threaded hole for the threaded column to extend into is provided at the rotating disk.
[0013] Through the present invention, the installer screws the rotating disk, thereby rotating the threaded column on the rotating column into the second threaded hole on the rotating disk, thereby connecting the rotating column with the rotating disk.
[0014] Preferably, a first handle is provided on the top of the rotating disk.
[0015] With the present invention, construction workers can rotate the first handle to drive the rotating disk to rotate, which makes it convenient for the construction workers to twist the rotating disk.
[0016] Preferably, two second handles are provided on the top wall of the cover plate.
[0017] With the present invention, the construction workers can lift the cover plate by holding the second handle, thereby facilitating the construction workers to lift the cover plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1 like Figure 1-10 As shown, this embodiment provides an orifice protective cover, including a protective cover body 100, the protective cover body 100 includes a circular cover plate 110; a circular mounting groove 420 is provided at the center of the bottom wall of the cover plate 110, and a plurality of arc grooves 240 are distributed circumferentially along the mounting groove 420; the arc groove 240 extends inward from the outer edge of the cover plate 110 and interferes with the mounting groove 420; a sliding plate 210 is provided in the arc groove 240, a limiting column 220 arranged perpendicular to the sliding plate 210 is provided at the sliding plate 210, and a rotating mechanism is provided in the mounting groove 420, and the rotating mechanism is used to push the sliding plate 210 to slide along the arc groove 240.
[0030] Through this embodiment, when the construction personnel use the cover plate 110, they need to twist the rotating disk 150, and the rotation of the rotating disk 150 drives the gear 230 to rotate, and the rotation of the gear 230 drives the multiple sliding plates 210 to slide along the arc groove 240. When the multiple sliding plates 210 move, the sliding plates 210 and the limiting columns 220 shrink toward the center of the cover plate 110, or spread toward the outside of the center of the cover plate 110; when the construction personnel need to cover the cover plate 110 on the pile hole opening, they only need to cover the cover plate 110 on the pile hole opening first, so that the cover plate 110 below The limiting column 220 extends into the pile hole, and then the rotating disk 150 is twisted to make the multiple limiting columns 220 spread outward from the center of the cover plate 110 and abut against the side wall of the pile hole, thereby fixing the cover plate 110 to prevent the cover plate 110 from being moved or damaged during construction; when the construction personnel need to remove the cover plate 110 from the pile hole opening, they only need to twist the rotating disk 150 in the opposite direction to make the limiting column 220 shrink toward the center of the cover plate 110, so as to release the squeezing of the limiting column 220 on the side wall of the pile hole, and then lift the cover plate 110 upward to open the pile hole; Since the limiting pillars 220 can be changed to different positions below the cover plate 110, the cover plate 110 can cover and be fixed on pile holes of different diameters.
[0031] In this embodiment, a groove 330 is provided along the length direction of the arc groove 240 at the side wall away from the mounting groove 420, and a limiting plate 730 is provided at the side wall of the sliding plate 210 to extend into the groove 330; a tooth groove 740 is provided along the length direction of the sliding plate 210 at one end of the sliding plate 210 away from the limiting plate 730; The rotating mechanism includes a gear 230 arranged in the mounting groove 420 and meshing with the tooth groove 740 on the sliding plate 210; a first through hole 410 passing through the cover plate 110 is provided at the center of the bottom wall of the mounting groove 420, and a rotating column 720 passing through the first through hole 410 is provided at the gear 230; a rotating disk 150 is provided at the end of the rotating column 720 away from the gear 230.
[0032] According to this embodiment, the construction personnel rotate the rotating disk 150 to drive the gear 230 to rotate, and the gear 230 rotates to drive the sliding plate 210 and the limiting pillars 220 on the sliding plate 210 to move, so that the plurality of limiting pillars 220 can spread outward and shrink inward along the center of the cover plate 110, thereby changing the spacing between the limiting pillars 220, so that the cover plate 110 can adapt to pile holes of different sizes; When the sliding plate 210 slides along the arc groove 240 , the limiting plate 730 on the sliding plate 210 slides along the groove 330 , thereby preventing the sliding plate 210 from escaping from the arc groove 240 and improving the stability of the sliding plate 210 when moving in the arc groove 240 .
[0033] In this embodiment, a plurality of first limiting grooves 510 distributed circumferentially along the first through hole 410 are provided on the top wall of the cover plate 110, and a second limiting groove 910 corresponding to the limiting groove 510 is provided on the bottom wall of the rotating disk 150; a limiting block 810 is provided in the second limiting groove 910, and a spring 920 for pushing the limiting block 810 into the first limiting groove 510; an arc-shaped surface 930 is provided at the end of the limiting block 810 away from the spring 920.

[0037] In this embodiment, a threaded column 710 is disposed at the top of the rotating column 720 , and a second threaded hole 820 for the threaded column 710 to extend into is disposed at the rotating disk 150 .
[0038] According to this embodiment, the installer screws the rotating disk 150 to rotate the threaded column 710 on the rotating column 720 into the second threaded hole 820 on the rotating disk 150 , thereby connecting the rotating column 720 to the rotating disk 150 .
[0039] In this embodiment, a first handle 130 is provided on the top of the rotating disk 150 .
