Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a protective structure for a support frame used in building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project, encompassing the building process of various structures. During construction, when workers need to work at heights, scaffolding is used to support them, enabling them to perform their tasks at elevated positions.

[0003] Currently, when using construction scaffolding for high-altitude construction, workers typically need to climb to the top of the scaffolding to perform their work. While existing construction scaffolding can provide safety protection for workers by installing guardrails at the top, preventing the risk of falls from heights, in actual use, the guardrails at the top of the scaffolding are usually at a fixed height. This makes the existing guardrails unsuitable for workers of different heights, failing to meet the actual needs of workers and thus reducing the protective effect on workers. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the protective railings installed on the support frame in the prior art cannot be used for workers of different heights and cannot meet the actual use needs of workers, thereby reducing the protective effect on workers. Therefore, a protective structure for the support frame used in construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective structure for a construction support frame includes a protective frame fixedly connected to the main body of the support frame. The protective frame is U-shaped and has openings at both ends. It also includes two protective plates connected to the protective frame via a driving part, wherein the two protective plates are distributed on both sides of the top of the protective frame, and the driving part is used to drive the protective plates to rise and fall; and two extension plates, both installed inside the protective frame via a connecting part, the connecting part being used to limit the extension range of the extension plates.

[0008] In order to extend the extension plates, wedge blocks are fixedly connected to the opposing surfaces of the two extension plates, and extrusion plates are fixedly connected to both sides of the straight rod, with the ends of the extrusion plates facing the wedge surfaces of the wedge blocks.

[0009] To limit the extension plate's telescopic movement, preferably, the connecting part includes a positioning block fixedly connected to the inner wall of the protective frame, and the extension plate has a sliding groove, with the positioning block slidably connected within the sliding groove; a compression spring is provided within the sliding groove, with both ends of the compression spring fixedly connected to the surface of the positioning block and the inner wall of the sliding groove, respectively.

[0010] To further reduce the friction between the extrusion plate and the wedge block, the end of the extrusion plate is rotatably connected to a rotating roller, which is rolled onto the wedge block.

[0011] To improve worker protection, preferably, connecting rods are fixedly connected to the outer walls of both extension plates, and protective rods are fixedly connected to the top of the connecting rods.

By adjusting the protective plate to a suitable height, the actual use needs of workers can be met, thereby improving the protective effect on workers.

[0015] 2. The protective structure of the support frame for building construction, by starting the motor and driving the straight rod to move, can adjust the height of the protective plate while also driving the extrusion plate and wedge block to move, so that the two extension plates extend out from the protective frame, thereby expanding the support area of ​​the protective frame, increasing the operating space for construction workers, and thus improving the practicality of the protective structure.

[0026] Example:

[0027] Reference Figures 1-7This utility model embodiment provides a protective structure for a construction support frame, including a protective frame 2 fixedly connected to the support frame body 1. The protective frame 2 is U-shaped, with a cavity inside and openings at both ends. It also includes two protective plates 4 connected to the protective frame 2 via a driving unit. The two protective plates 4 are distributed on both sides of the top of the protective frame 2. The driving unit is used to drive the protective plates 4 to rise and fall, and can adjust the protective height of the protective plates 4. Two extension plates 6 are installed inside the protective frame 2 via connecting parts, and the connecting parts are used to limit the extension range of the extension plates 6.

[0028] Specifically, during use, by starting the motor 51, the output end of the motor 51 drives the rotating rod 52 to rotate, which in turn drives the meshing bevel gear 55 and screw 54 to rotate. This enables the straight rod 3 to drive the protective plate 4 to move longitudinally, thereby achieving rapid adjustment of the protective height of the protective plate 4. This can meet the actual needs of workers and improve the protective effect on workers. Furthermore, by extending the extension plate 6 from inside the protective frame 2, the support area of ​​the protective frame 2 can be expanded, thereby improving the practicality of the protective structure.

[0029] The drive unit includes: a motor 51, which is fixedly connected to the outer wall of the protective frame 2; wherein, a rotating rod 52 is rotatably connected inside the protective frame 2, the output end of the motor 51 is fixedly connected to one end of the rotating rod 52, a pair of support plates 53 are fixedly connected inside the protective frame 2, and a screw 54 is rotatably connected to each of the two support plates 53; bevel gears 55 that mesh with each other are fixedly connected to the outer walls on both sides of the rotating rod 52 and the bottom ends of the two screws 54, and a straight rod 3 is threadedly connected to each of the two screws 54; the straight rod 3 is slidably connected to the protective frame 2 in the longitudinal direction, and a protective plate 4 is fixedly connected to the top end of the straight rod 3.

[0030] Specifically, during use, by starting the motor 51, the output end of the motor 51 drives the rotating rod 52 to rotate, which in turn drives the meshing bevel gear 55 to rotate, and at the same time drives the two screws 54 to rotate. Under the action of the screws, the straight rod 3 can drive the protective plate 4 to move longitudinally.

[0031] Both extension plates 6 are fixedly connected to the opposing surfaces of the two extension plates 6, and both sides of the straight rod 3 are fixedly connected to the extrusion plates 8, with the ends of the extrusion plates 8 facing the wedge-shaped surfaces of the wedge blocks 7.

[0032] Specifically, when the straight rod 3 moves upward, it drives the pressing plates 8 on both sides and the rotating roller 10 to move together, so that the rotating roller 10 rolls and presses on the wedge surface of the wedge block 7, causing the two extension plates 6 to slide apart within the protective frame 2, thereby extending the extension plates 6 out of the protective frame 2.

[0033] The connecting part includes a positioning block 91 fixedly connected to the inner wall of the protective frame 2, and a slide groove 92 is provided on the extension plate 6. The positioning block 91 is slidably connected in the slide groove 92. A compression spring 93 is provided in the slide groove 92, and the two ends of the compression spring 93 are fixedly connected to the surface of the positioning block 91 and the inner wall of the slide groove 92, respectively.

[0034] Specifically, during use, when the straight rod 3 moves upward and drives the extrusion plates 8 on both sides to move together, the extrusion plates 8 extrude pressure on the wedge block 7, causing the two extension plates 6 to slide in opposite directions within the protective frame 2. The sliding distance of the extension plates 6 can be limited by the positioning block 91 and the slide groove 92 to prevent the extension plates 6 from falling off. Furthermore, the compression spring 93 can elastically position the extension plates 6 to prevent them from moving arbitrarily.

[0035] The end of the extrusion plate 8 is rotatably connected to a rotating roller 10, which is rolled on the wedge block 7.

[0036] Specifically, by setting the rotating roller 10, the friction between the extrusion plate 8 and the wedge block 7 when they come into contact can be reduced, thereby improving the driving effect on the extension plate 6.

[0037] Connecting rods 11 are fixedly connected to the outer walls of both extension plates 6, and protective rods 12 are fixedly connected to the top of the connecting rods 11.

[0038] Specifically, the installation of connecting rod 11 and protective rod 12 can further protect construction workers and prevent them from falling from heights, thereby further improving the safety of the support frame.

[0039] Both sides of the top of the protective frame 2 are fixedly connected with telescopic sleeves 13, and the ends of the telescopic sleeves 13 are fixedly connected to the bottom of the protective plate 4.

[0040] Specifically, the telescopic sleeve 13 can support and guide the protective plate 4, thereby improving the stability of the protective plate 4 in use.

[0041] Working principle: During use, when the protective height of the protective plate 4 needs to be adjusted, the motor 51 can be started. The output end of the motor 51 drives the rotating rod 52 to rotate, which in turn drives the meshing bevel gear 55 to rotate. At the same time, it drives the two screws 54 to rotate. Under the action of the screws, the straight rod 3 can be driven to move the protective plate 4 longitudinally, so as to quickly adjust the protective height of the protective plate 4 to suit workers of different heights. By adjusting the protective plate 4 to a suitable height, the actual use needs of workers can be met, thereby improving the protective effect on workers.

[0042] Furthermore, during the adjustment process, when the straight rod 3 moves upward, it drives the pressing plates 8 and the rotating roller 10 on both sides to move together, causing the rotating roller 10 to roll and press on the wedge surface of the wedge block 7, causing the two extension plates 6 to slide apart within the protective frame 2, and compressing the compression spring 93 through the positioning block 91, thereby extending the extension plates 6 out of the protective frame 2.

[0043] When the straight rod 3 moves downward, under the elastic force of the compression spring 93, the two extension plates 6 retract into the protective frame 2. The straight rod 3 drives the pressing plate 8 to move, which can adjust the height of the protective plate 4 and drive the wedge block 7 to move, so that the two extension plates 6 extend out of the protective frame 2. This can expand the support area of ​​the protective frame 2, increase the operating space of construction workers, and thus improve the practicality of the protective structure. This solves the problem that the protective railings installed on the load-bearing frame in the existing technology cannot be used by workers of different heights and cannot meet the actual use needs of workers, thus reducing the protective effect on workers.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
