Description

Technical Field

[0001] This utility model relates to the field of wind and rain shelter technology, and in particular to a wind and rain shelter for high-altitude truss operations. Background Technology

[0002] Truss: A structure consisting of members connected to each other at both ends by hinges. A truss is a planar or spatial structure composed of straight members, generally with triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight, and increase stiffness compared to solid beams.

[0003] When working on trusses, due to the significant height and weather conditions such as high winds, rain, or snow, it is necessary to construct a covered awning. This provides construction workers with a relatively stable working environment or reduces construction interference, thereby improving welding and painting quality. Traditionally, covered awnings are mostly constructed by covering the scaffolding with a three-color tarpaulin. However, installing the three-color tarpaulin is relatively difficult and offers limited wind protection. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a windproof canopy for high-altitude truss operations, comprising several frame rods, a fabric rolling mechanism, and corner connectors. The frame rods and corner connectors form a square frame, and the fabric rolling mechanism is installed on each side of the frame. The frame rods and corner connectors form the frame, and then the fabric rolling mechanism is installed on each side of the frame, namely the side surface and the top surface of the frame.

[0005] The fabric rolling mechanism includes a housing with end caps fixedly connected to both ends. A rotating rod is disposed inside the housing, and a fixing block is fixedly connected to the rotating rod. A coil spring is fixedly connected to one side of the fixing block, and the other end of the coil spring is fixedly connected to the end caps. A roller is sleeved on the outside of the coil spring, and tarpaulin is wound around the side wall of the roller. Pulling the tarpaulin outwards allows the coil spring to store elastic potential energy. When the tarpaulin needs to be rolled up, the coil spring releases the elastic potential energy to roll the tarpaulin inside the housing, protecting the tarpaulin and increasing the number of times it can be reused.

[0006] Preferably, a first mounting plate is fixedly connected to the lower part of the outer casing, and the first mounting plate is provided with through holes. The outer casing is fixed by the first mounting plate.

[0007] Preferably, one end of the tarpaulin is fixedly connected to a second mounting plate, and the second mounting plate is provided with a through hole. The second mounting plate is used to fix the tarpaulin, and together with the first mounting plate, it enables the tarpaulin to be pulled out and held in place.

[0008] Preferably, the frame rod includes an angle steel, and rubber magnetic strips are provided on both inner sidewalls of the angle steel. A clamping rod is provided on the rubber magnetic strips. The angle steel has a first threaded hole, and the clamping rod has a through hole, the position of which corresponds to the position of the first threaded hole. The first threaded hole is provided for fixing with bolts.

[0009] Preferably, the corner connector includes a main body, on which a slot and a second threaded hole are provided. The second threaded hole, when engaged with a bolt, serves to fix the frame rod.

[0010] Preferably, the end of the frame rod fits into the slot, and the end of the frame rod is provided with a through hole, the position of which mates with the second threaded hole. That is, the bolt passes through the through hole at the end of the frame rod and connects with the second threaded hole to fix the frame rod.

[0011] The beneficial effects of this utility model are as follows: 1. It features a modular structure with frame rods, a fabric rolling mechanism, and corner connectors, which facilitates assembly.

[0012] 2. Rubber magnetic strips and fastening rods are installed on the frame poles to fasten and fix the edges of the tarpaulin, thereby improving the windproof effect of the constructed awning.

[0013] 3. The fabric rolling mechanism is designed to roll up the tarpaulin inside the outer shell using a spring, which facilitates storage after disassembly and subsequent reuse. Attached Figure Description

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1 to 6 As shown, a windproof canopy for high-altitude truss operations includes several frame rods 1, a fabric rolling mechanism 2, and corner connectors 3. The frame rods 1 and corner connectors 3 form a square frame, and the corner connectors 3 connect the frame rods 1 together. The fabric rolling mechanism 2 is set on each side of the frame.

[0018] The fabric rolling mechanism 2 includes a housing 22, which is a thin, circular shell with an opening on its circumference. End caps 27 are fixedly connected to both ends of the housing 22. A rotating rod 26 is disposed inside the housing 22, with its end rotatably fitted to the center of the end caps 27. A fixing block 24, a cylinder, is fixedly connected to the rotating rod 26. A coil spring 25, also cylindrical, is fixedly connected to one side of the fixing block 24. The coil spring 25 stores and releases elastic potential through the rotation of a pivot. Yes, its working principle is the same as that used in roller shutters. The other end of the coil spring 25 is fixedly connected to the end cover 27. That is, during the rotation of the rotating rod 26, the elastic potential energy stored in the coil spring 25 also changes. A roller 29 is sleeved on the outside of the coil spring 25. Furthermore, the roller 29 is fixedly connected to the fixing block 24. During the rotation of the rotating rod 26, the roller 29 also rotates with the rotating rod 26. A tarpaulin 23 is wound around the side wall of the roller 29. That is, the rotation of the roller 29 is used to roll up and down the tarpaulin 23.

[0019] After the fabric rolling mechanism 2 is assembled, the coil spring 25 has a pre-tensioning effect, that is, it keeps the tarpaulin 23 rolled up inside the outer shell 22. When in use, the tarpaulin 23 can be pulled out from the outer shell 22. At this time, since the roller 29 drives the rotating rod 26 to rotate, the coil spring 25 stores elastic potential energy. When the tarpaulin 23 is not subjected to external force, the coil spring 25 can release elastic potential energy to roll up the tarpaulin 23.

[0020] The lower part of the outer casing 22 is fixedly connected to a first mounting plate 21. The first mounting plate 21 and the outer casing 22 are integral structures, and the first mounting plate 21 is provided with through holes for inserting bolts for fixing.

[0021] One end of the tarpaulin 23 is fixedly connected to a second mounting plate 28. The second mounting plate 28 is designed to facilitate pulling the tarpaulin 23. The second mounting plate 28 is provided with through holes, which are also designed to facilitate the insertion of bolts for fixing.

[0022] The frame pole 1 includes an angle steel 11, with rubber magnetic strips 14 installed on both inner sidewalls of the angle steel 11. The rubber magnetic strips 14 pre-fix the two edges of the tarpaulin 23. A clamping rod 13 covers the rubber magnetic strips 14. A first threaded hole 12 is provided on the angle steel 11, and a through hole is provided on the clamping rod 13. The position of the through hole corresponds to the position of the first threaded hole 12. Bolts can be used to pass through the through hole and the first threaded hole 12 to fix the clamping rod 13 to the angle steel 11, thus tightly clamping the rubber magnetic strips 14 and firmly fixing the tarpaulin 23. Furthermore, the first threaded hole 12 can also be used to fix the first mounting plate 21 or the second mounting plate 28.

[0023] The corner connector 3 includes a main body 31, a slot 32, and a second threaded hole 33. Its specific structure is as follows: Figure 6 As shown, frame rod 1 can be fixed in three directions respectively.

[0024] The end of the frame rod 1 is fitted into the slot 32, and the end of the frame rod 1 is provided with a through hole, and at least four through holes are provided. The through hole positions are matched with the second threaded hole 33. Specifically, the end of the angle steel 11 is inserted into the slot 32, and then the frame rod 1 and the angle connector 3 are fixed together with bolts.

[0025] During installation, the end of the angle steel 11 is inserted into the slot 32 and fixed with bolts in the second threaded hole 33 to achieve a fixed connection between the frame rod 1 and the corner connector 3. After multiple connections, the frame rod 1 and the corner connector 3 form a cuboid frame. Then, the fabric rolling mechanism 2 is fixed to the frame. First, a bolt is inserted into the second mounting plate 28, and the bolt is threaded into the first threaded hole 12 on one of the angle steels. Then, the outer shell 22 is pulled away from the second mounting plate 28, so that the tarpaulin 23 is released from the outer shell 22. When the first mounting plate 21 is leaning against another angle steel 11, the bolt passes through the through hole on the first mounting plate 21 and is fixed to the first threaded hole 12 on the angle steel 11. Next, the rubber magnetic strips 14 and the fastening rods 13 on the angle steels 11 on both sides of the tarpaulin 23 are removed. At this time, the edge of the tarpaulin 23 is attached to the angle steels 11 on both sides. Finally, the rubber magnetic strips 14 are used for pre-fixing, and the fastening rods 13 are inserted into the bolt and fixedly connected to the first threaded hole 12 on the angle steels 11 on both sides, realizing the fastening of the rubber magnetic strips 14 and tightening, preventing the tarpaulin 23 from detaching from the angle steels 11 on both sides, and ensuring the protective effect.
