Description

Technical Field

[0001] The present invention relates to the technical field related to horizontal hole protection, and in particular to an assembled horizontal hole protection device. Background Art

[0002] During the construction process of a building project, in order to prepare for subsequent construction in advance, it is often necessary to reserve some openings on the floor slabs, such as lifting openings, reserved openings, and various horizontal openings such as shaft openings. However, the existence of these open horizontal openings poses a greater safety hazard such as falling people and objects, so they need to be covered by protective devices.

[0003] After searching the invention patent with patent number CN114059787B, a horizontal hole protection device with flexible adjustment and turnover is disclosed, which includes a cover plate, which covers the upper end of the hole of the floor plate, and a cross rod is provided on the upper end surface of the cover plate to be clamped with the floor plate. The upper end surface of the cover plate is located between the adjacent rods of the cross rod and is provided with four groups of adjustment slots distributed in a circumferential array. The four groups of adjustment slots distributed in the circumferential array are respectively provided with connecting screws fixedly connected to the floor plate. By providing a rotating pressed rotating plate, the offset length between the floor plate is increased, the pressing area is increased, and the pressure bearing strength of the cover plate is increased. At the same time, the staggered plug-in of the cover plate is realized by the cooperation between the plug column and the plug hole on the rotating plate. The cover plate is locked by the position of the card cover, which prevents the cover plate from being flipped up at will, further improving safety.

[0004] The horizontal opening protection devices used in the above patents and prior art still have certain shortcomings, such as:

[0005] 1. In the aforementioned patent, the crossbeam rises, causing the rotating plate to rotate relative to the crossbeam, thereby enabling the insertion of the plug-in column and the socket, and thus achieving the staggered engagement of the lower end of the cover plate. This requires close coordination between the crossbeam, the rotating plate, and the cover plate, and none of the crossbeam, the rotating plate, or the cover plate has an adjustment structure. In other words, the protective device in the aforementioned patent cannot be adaptively adjusted to the specifications, sizes, and shapes of different horizontal openings, greatly reducing its scope of application.

[0006] 2. Existing horizontal opening protection mostly uses a cover plate, which does not have a limiting mechanism or locking mechanism. The cover plate is easily moved out of the horizontal opening during construction, posing a safety hazard. In addition, the existing cover plate and the protective device in the above patent cannot be folded. In order to fit the horizontal opening, the protective device is large and cannot be folded, which greatly affects its transportation and portability.

[0007] Therefore, we propose an assembled horizontal hole protection device to solve the above problems. Summary of the Invention

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-10 , the present invention provides a technical solution: an assembled horizontal hole protection device, including a housing base 1, and also including a support mechanism 2 and a baffle assembly 17.

[0040] Before using this assembled horizontal hole protection device, through the support assistance of the support mechanism 2, the positioning and placement of the housing base 1 are carried out. Specifically, as shown in Figure 2 , Figure 3 and Figure 5 , an integrally - structured shaft column is vertically arranged at the center position of the driving gear 15. Bearings are installed at the middle of the upper shaft column and the end of the lower shaft column respectively. After the driving gear 15 is placed, two of the bearings are respectively fixedly clamped on the two side cavity walls in the housing base 1, and the upper shaft column passes through the cavity wall of the housing base 1 and extends to the outside. Since the rotating handle 16 is fixedly connected to the end of the upper shaft column of the driving gear 15 by bolts and forms a synchronous rotation structure with the driving gear 15, when the rotating handle 16 is rotated, the driving gear 15 rotates in the seat cavity of the housing base 1 with the assistance of the bearings. Also, since the driven gear 11 is connected to the driving gear 15 in a meshing manner, when the driving gear 15 rotates, the driven gear 11 is driven to rotate synchronously through the meshing action between the driving gear 15 and the driven gear 11;

[0041] Since bearings are installed at both the upper and lower ends of the shaft pipe member 10, and after installation, the bearings at both ends are respectively fixed and clamped on the cavity walls on both sides in the housing base 1. Also, since the driven gear 11 is sleeved and fixedly connected to the middle pipe body of the shaft pipe member 10 through bolts, and it forms a synchronous rotation structure with the shaft pipe member 10. During the rotation of the driven gear 11, the shaft pipe member 10 is assisted by the bearings to rotate in the cavity of the housing base 1;

[0042] Since the shaft pipe member 10 is movably sleeved on the upper column body of the separation column 9, and the cross-section of the upper column body of the separation column 9 is arranged in a square structure. After installation, it is movably clamped in the pipe cavity of the shaft pipe member 10 and is movably positioned on the shaft pipe member 10. Also, since the second bevel gear 8 is sleeved and fixedly connected to the lower end of the separation column 9 through bolts. During the rotation of the shaft pipe member 10, it drives the separation column 9 to rotate synchronously and makes the separation column 9 drive the second bevel gear 8 to rotate;

[0043] Since bearings are installed at both ends of the adjusting screw rod 3, and after installation, the bearings at both ends are respectively fixed and clamped on the cavity walls on both sides in the housing base 1. The first bevel gear 7 is sleeved and fixedly connected to the middle rod body of the adjusting screw rod 3 through bolts, and it forms a synchronous rotation structure with the adjusting screw rod 3. Also, since the upper side of the first bevel gear 7 is meshed and connected with the second bevel gear 8 and is arranged perpendicular to the second bevel gear 8. During the rotation of the second bevel gear 8, through the meshing action between the second bevel gear 8 and the first bevel gear 7, it drives the first bevel gear 7 to rotate synchronously and makes the adjusting screw rod 3 rotate in the cavity of the housing base 1 with the assistance of the bearings;

[0044] Since movable blocks 4 are movably installed on one section of the screw rod body and the other section of the screw rod body of the adjusting screw rod 3. After installation, the movable blocks 4 are sleeved on the screw rod body in the adjusting screw rod 3 and are connected to the screw rod body in the adjusting screw rod 3 in a way of movable penetration. They are movably clamped in the cavity of the housing base 1, and the middle plate body thereof movably penetrates through the chute in the housing base 1 and extends to the outside. Also, since the thread rotation direction of one section of the screw rod body in the adjusting screw rod 3 is opposite to that of the other section of the screw rod body, and the screw rod body is threadedly connected to the groove wall of the movable block 4. During the rotation of the adjusting screw rod 3, the two movable blocks 4 on the adjusting screw rod 3 slide in opposite directions synchronously;

[0045] Since the maximum width dimension of the scissor expansion frame 5 is smaller than the width dimension of the housing base 1, the scissor expansion frame 5 is arranged horizontally on the housing base 1 after installation. The two end parts of its end are respectively rotatably connected to the plate bodies of the two movable blocks 4 with the assistance of shaft bolts. Also, since the longitudinal section of the claw frame 6 is in an "L" - shaped structure, the two end parts of the head of the scissor expansion frame 5 are both threadedly connected with the claw frame 6. The claw frame 6 is arranged vertically on the frame of the scissor expansion frame 5 after installation. During the sliding of the two movable blocks 4, the scissor expansion frame 5 drives the claw frame 6 to perform an expansion or contraction movement;

[0046] According to the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, four support mechanisms 2 are arranged in a circular array on the housing base 1 with the center of the housing base 1 as the center of the circle. Based on the above, when dealing with square and circular horizontal holes, that is, horizontal holes with equal length and width, keep the first bevel gear 7 and the second bevel gear 8 in a meshing state among the four support mechanisms 2. When driving the driving gear 15 to rotate, it drives the four driven gears 11 to rotate synchronously. Through the linkage between the separation column 9 and the shaft pipe part 10, it drives the four second bevel gears 8 to rotate synchronously. Through the meshing effect between the first bevel gear 7 and the second bevel gear 8, it drives the four adjusting screw rods 3 to rotate. Through the threaded connection between the adjusting screw rod 3 and the movable block 4, it drives the four scissor-type telescopic frames 5 to extend and unfold or contract and fold. When the scissor-type telescopic frames 5 extend and unfold, the claw holders 6 in the four scissor-type telescopic frames 5 respectively overlap on the four side edges of the horizontal hole to support and fix the housing base 1. When the scissor-type telescopic frames 5 contract and fold, the claw holders 6 in the four scissor-type telescopic frames 5 are separated from the horizontal hole synchronously to disassemble the housing base 1;

[0047] Based on the above, when dealing with rectangular, oval or irregular horizontal holes, that is, horizontal holes with unequal length and width, first drive the driving gear 15 to rotate. Through the transmission among the driven gear 11, the shaft pipe part 10, the separation column 9, the second bevel gear 8, the first bevel gear 7, the movable block 4 and the adjusting screw rod 3, drive the two opposite scissor-type telescopic frames 5 to support at the narrowest spacing of the horizontal hole. Then, for the two supported support mechanisms 2, release the meshing effect between the first bevel gear 7 and the second bevel gear 8. That is, when the driving gear 15 rotates again, it does not drive the two supported support mechanisms 2, but only drives the two unsupported support mechanisms 2, so that the scissor-type telescopic frames 5 in the two unsupported support mechanisms 2 support at the longest spacing of the horizontal hole. In addition, the claw holder 6 forms a disassembly structure on the frame of the scissor-type telescopic frame 5. When the two claw holders 6 on the scissor-type telescopic frame 5 affect the overlap with the side edge of the horizontal hole, one of the claw holders 6 can be disassembled to meet the overlap requirement;

[0048] After the first bevel gear 7 and the second bevel gear 8 are released, the upper end of the shaft tube 10 is movably inserted through the seat wall of the shell seat 1 to extend to the outside, and the shaft tube 10 is connected to the separation column 9 in a movably through-through manner. The upper end of the separation column 9 is provided with a pull ring portion of an integrated structure, and the separation column 9 is pulled up by the pull ring portion to make the separation column 9 slide in the tube cavity of the shaft tube 10. Since the spherical ball 12 is in a movable state after being placed, it is stuck in the groove cavity of the separation column 9 and is symmetrically arranged about the vertical center axis of the separation column 9. A return spring 13 is installed at the connection between the spherical ball 12 and the separation column 9. After the return spring 13 is placed, it is placed in the gap between the two spherical balls 12 and is located in the groove cavity of the separation column 9. One end of the return spring 13 rests on one spherical ball 12 and the other end rests on the other spherical ball 12. In addition, since the upper and lower tube walls of the shaft tube 10 are provided with positioning grooves 14, the positioning grooves 14 on the upper and lower tube walls are all about the shaft tube 1 0 is symmetrically arranged, and the positioning groove 14 is arranged in a hemispherical structure state, and its maximum distance dimension is smaller than the diameter dimension of the spherical ball 12, and the spacing dimension between the two positioning grooves 14 is equal to the sliding distance dimension of the separation column 9. When the first bevel gear 7 and the second bevel gear 8 are in the meshing state, the spherical ball 12 is engaged and connected with the lower positioning groove 14 to position the separation column 9, that is, to position the second bevel gear 8 in the meshing state. During the pulling process of the separation column 9, the spherical ball 12 is pushed and slides in the groove cavity of the middle column of the separation column 9, and loses the engagement connection with the lower positioning groove 14, and causes the reset spring 13 to be squeezed and elastically deformed. After the separation column 9 is pulled, the second bevel gear 8 is driven to separate from the first bevel gear 7, and the elastic deformation of the reset spring 13 is used to reset, so that the spherical ball 12 is engaged and connected with the upper positioning groove 14, thereby positioning the pulled separation column 9, that is, positioning the separated second bevel gear 8;

[0049] When using the assembled horizontal hole protection device, the baffle assembly 17 is placed to block the horizontal hole. Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, specifically, the single baffle 19 is arranged in an equally divided fan-shaped structure, and it is arranged in a circular array with the center of the baffle assembly 17 as the center of the circle. Since a connecting plate 20 is movably installed at the connection between the single baffle 19 and the single baffle 19, the width dimension of the connecting plate 20 is greater than the sum of the thickness dimensions of the two single baffles 19, and one end of the connecting plate 20 forms a rotating structure on the side of a single baffle 19 with the assistance of a bolt, and the other end of the connecting plate 20 is rotatably connected to the side of another adjacent single baffle 19 with the assistance of a bolt. With the assistance of the connecting plate 20, all the single baffles 19 are turned over and unfolded in sequence. Also, since a "U" - shaped rod 21 is arranged between the first - end single baffle 19 and the last - end single baffle 19 in the baffle assembly 17, after the "U" - shaped rod 21 is installed, one of its rod bodies is inserted into the side of the first - end single baffle 19, and the other rod body is inserted into the side of the last - end single baffle 19. Both ends of the end head 22 are rotatably connected with bolt caps, and two of the bolt caps are respectively arranged corresponding to the two rod bodies of the "U" - shaped rod 21. By screwing and rotating the bolt caps in the end head 22, the bolt caps are thread - connected to the ends of the "U" - shaped rod 21, locking the "U" - shaped rod 21, that is, locking between the first - end single baffle 19 and the last - end single baffle 19. After the baffle assembly 17 is unfolded, it is arranged in a circular - ring - shaped structure state;

[0050] Since the upper seat body of the housing base 1 is in a disc - shaped structure, and an integrated support ring part protrudes from the outside of the disc - shaped seat body in the housing base 1, and the upper side wall of the support ring part in the housing base 1 is on the same horizontal plane as the upper side wall of the transverse frame body in the claw holder 6. When arranging the baffle assembly 17, the baffle assembly 17 is movably sleeved on the disc - shaped seat body in the housing base 1, so that the inner plate body of the baffle assembly 17 overlaps on the support ring part in the housing base 1, and the outer plate body of the baffle assembly 17 overlaps on the transverse frame body in the claw holder 6, that is, overlaps on the edge of the horizontal hole. Then, the protective cover 18 is covered and clamped on the disc - shaped seat body in the housing base 1, and its lower side wall presses against the inner plate body of the baffle assembly 17 to limit the arranged baffle assembly 17;

[0051] This is the entire working process of this assembled horizontal - hole protection device. The content not described in detail in this specification belongs to the prior art well - known to those skilled in the art.
