Description

Technical Field

[0001] The invention belongs to the technical field of protective devices, and in particular relates to a tool-type protective device for a flue opening. Background Art

[0002] Construction sites are one of the high-risk industries. The most common hidden danger during construction is the edge opening, especially the flue opening, which is large in size and prone to high-fall risks. In recent years, a large number of construction sites have adopted aluminum formwork for construction. Unlike conventional wooden formwork, due to the presence of aluminum formwork K-plate, the flue opening is blocked by the K-plate, making it inconvenient to set up horizontal protection, resulting in a long-term high-fall hazard. Summary of the invention

[0003] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a tool-type protection device for a flue opening.

[0004] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A tool-type protection device for a flue hole, comprising a fixing mechanism, a baffle mechanism is hingedly mounted on the fixing mechanism, and the other end of the baffle mechanism is connected to a hanging mechanism;

[0006] The fixing mechanism comprises an upper fixing seat, the upper fixing seat is L-shaped, first sliding grooves are provided on both sides of the upper fixing seat, a lower fixing seat is slidably mounted in the first sliding grooves, the lower fixing seat is L-shaped, and two fastening screws are installed between the lower fixing seat and the upper fixing seat;

[0007] The baffle mechanism includes a main board hinged to the upper fixing seat, the main board is transversely provided with two groups of first slides, the first slide is L-shaped in cross section, the first slide is slidably mounted with a main board extension plate, the main board is symmetrically fixedly mounted with four first studs, the main board extension plate is provided with a first waist-shaped hole whose specification and position match the first stud, the first stud is threadedly connected with a first nut, the main board is provided with a second slide groove, the second slide groove is slidably mounted with a sub-plate, the sub-plate is provided with two groups of second slides with the same direction as the first slide, the second slide is L-shaped in cross section, the second slide is slidably mounted with a sub-plate extension plate, the sub-plate is symmetrically fixedly mounted with four second studs, the sub-plate extension plate is provided with a second waist-shaped hole whose specification and position match the second stud, the second stud is threadedly connected with a second nut;

[0008] The hanging mechanism comprises a lifting ring fixedly mounted on the end of the auxiliary plate extension plate, the lifting ring is connected with a steel rope, and the end of the steel rope is connected with a hook.

[0009] It is further defined that a limit cylinder matching the specifications of the fastening screw and nut is welded at the bottom of the lower fixing seat. Such a design prevents the fastening screw from rotating with the nut when the fastening screw is rotated, which is not conducive to pulling the lower fixing seat to move and locking the fastening screw.

[0010] It is further defined that the main board extension plate and the sub-board extension plate are both integrally connected with a pull strip, and such a design facilitates pulling the main board extension plate and the sub-board extension plate.

[0011] It is further defined that the main board extension plate and the sub-board extension plate are exactly the same. Such a design does not require coordinated use, which facilitates spare parts and quick installation.

[0012] It is further specified that the overall thickness of the main board and the sub-board is five millimeters. This design ensures the load-bearing effect while not being too heavy.

[0013] It is further defined that the main plate and the auxiliary plate are both steel plates. Such a design is rust-resistant and has good load-bearing effect.

[0014] The beneficial effects of the present invention are as follows:

[0015] The present invention has a reasonable structure. The fixing mechanism is fixed on the edge of the hole, and then the hanging mechanism is used to hang on the aluminum film K plate. The baffle mechanism can achieve the closure and blocking of the hole, thereby achieving a protective effect. Moreover, because it is hinged, the baffle mechanism can also be tilted to block and prevent materials from being piled on it.

[0016] The structure of the present invention is simple to install and disassemble, convenient to use and carry, and convenient to use multiple times, thus reducing costs.

[0017] Under the effect of the main board extension plate and the sub-board extension plate, the present invention can adjust the protection area, and thus can adapt to the protection of holes of different specifications and sizes, and has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1 to Figure 4 As shown, a tool-type protection device for a flue hole of the present invention comprises a fixing mechanism 1, a baffle mechanism 2 is hingedly mounted on the fixing mechanism 1, and a hanging mechanism 3 is connected to the other end of the baffle mechanism 2;

[0030] The fixing mechanism 1 includes an upper fixing seat 101, the upper fixing seat 101 is L-shaped, and first slide grooves 102 are provided on both sides of the upper fixing seat 101. A lower fixing seat 103 is slidably installed in the first slide grooves 102. The lower fixing seat 103 is L-shaped, and two fastening screws 104 are installed between the lower fixing seat 103 and the upper fixing seat 101;

[0031] The baffle mechanism 2 includes a main board 201 hinged to the upper fixing seat 101, the main board 201 is laterally provided with two sets of first slideways 202, the first slideway 202 has an L-shaped cross section, the first slideway 202 is slidably installed with a main board extension plate 203, the main board 201 is symmetrically fixed with four first studs 204, the main board extension plate 203 is provided with a first waist-shaped hole 205 whose specification and position match the first stud 204, the first stud 204 is threadedly connected with a first nut 206, and the main board 201 is provided with a second slide The second slide groove 207 is slidably mounted with a sub-plate 208, the sub-plate 208 is provided with two sets of second slideways 209 in the same direction as the first slideway 202, the second slideway 209 is L-shaped in cross section, the second slideway 209 is slidably mounted with a sub-plate extension plate 210, the sub-plate 208 is symmetrically fixedly mounted with four second studs 211, the sub-plate extension plate 210 is provided with a second waist-shaped hole 212 whose specification and position match the second stud 211, and the second stud 211 is threadedly connected with a second nut 213;

[0032] The hanging mechanism 3 includes a lifting ring 301 fixedly mounted on the end of the auxiliary plate extension plate 210 , the lifting ring 301 is connected to a steel rope 302 , and the end of the steel rope 302 is connected to a hook 303 .

[0033] In this embodiment, when using a tool-type protective device for the flue opening, the fixing mechanism 1 is fixed to the edge of the opening, and then the hanging mechanism 3 is hung on the aluminum film K plate on the side of the opening, so that the baffle mechanism 2 can complete the protection of the opening and achieve the protection purpose. It should be noted that in this protection method, when the length of the baffle mechanism 2 is greater than the opening, it can also be directly overlapped on the aluminum film K plate without hanging, which further simplifies the use method;

[0034] Specifically, the upper fixing seat 101 is overlapped on the upper side of the edge of the hole, and then the lower fixing seat 103 is suspended on the lower side of the edge of the hole, and then the fastening screw 104 is rotated. Under the effect of the spiral force, the lower fixing seat 103 moves toward the direction of the upper fixing seat 101, thereby achieving the purpose of clamping and fixing the upper fixing seat 101 and the lower fixing seat 103 on the edge of the hole, and this method can adapt to the installation of the edges of holes of different thicknesses without damaging the edges of the hole, and then the hook 303 is hung on the aluminum film K plate, and the baffle mechanism 2 is naturally tilted and overlapped above the hole.

[0035] Furthermore, when the specification of the baffle mechanism 2 does not match the size of the hole, further adjustment can be made by pulling the mainboard extension plates 203 on both sides of the mainboard 201 to widen the lateral shielding area of ​​the mainboard 201, and then tightening the first nut 206 on the first stud 204 to fix the position of the active extension plate 203 to prevent displacement due to force, thereby exposing the hole. This is width adjustment;

[0036] By pulling the sub-plate 208 on the lower side of the main plate 201, the overall length of the main plate 201 and the sub-plate 208 can be changed directly, and the hanging mechanism 3 is installed on the sub-plate 208, so the sub-plate 208 is not easy to retract into the main plate 201 after the length changes, thereby realizing the length adjustment;

[0037] When both the length and the width need to be changed, the width of the main board 201 is adjusted first, and then the sub-board 208 is pulled out, and the width of the sub-board extension board 210 is adjusted and fixed in the same way as the main board extension board 203 is adjusted and fixed, so as to adapt to a longer and wider hole;

[0038] In summary, the present structure has wide adaptability and can be adapted to the protection of openings of different specifications and sizes, and is simple and convenient to install. Moreover, the entire protective device can be disassembled by disassembling the fixing mechanism 1, thereby achieving the purpose of recycling and reuse.

[0039] Preferably, a limiting cylinder 105 matching the specifications of the nut of the fastening screw 104 is welded to the bottom of the lower fixing seat 103. Such a design prevents the fastening screw 104 from rotating along with the nut of the fastening screw 104 when the nut is rotated, which is not conducive to pulling the lower fixing seat 103 to move and locking the fastening screw 104. In fact, a structure to prevent the fastening screw 104 from rotating under force can also be considered according to specific circumstances.

[0040] Preferably, the main board extension plate 203 and the sub-board extension plate 210 are integrally connected with a pull strip 214. Such a design is conducive to pulling the main board extension plate 203 and the sub-board extension plate 210. In fact, measures to facilitate pulling the main board extension plate 203 and the sub-board extension plate 210 can also be considered according to specific circumstances, such as opening a handle.

[0041] Preferably, the main board extension plate 203 and the sub-board extension plate 210 are exactly the same. Such a design does not require coordination for use, is convenient for spare parts and quick installation. In fact, the specifications and dimensions of the main board extension plate 203 and the sub-board extension plate 210 can also be customized according to specific circumstances.

[0042] Preferably, the overall thickness of the main board 201 and the sub-board 208 is five millimeters. This design ensures the load-bearing effect while not being too heavy. In fact, the overall thickness of the main board 201 and the sub-board 208 can also be considered according to specific circumstances.

[0043] Preferably, both the main plate 201 and the auxiliary plate 208 are steel plates. Such a design is rust-resistant and has good load-bearing effect. In fact, the material selection of the main plate 201 and the auxiliary plate 208 can also be considered according to specific circumstances.
