[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-5 As shown, this utility model provides a protective support for civil engineering construction, including a chassis 1. Several counterweights 11 are fixedly installed on the lower surface of the chassis 1. By setting the counterweights 11, the stability of the chassis 1 can be improved, thereby improving the stability of the protective support. A hollow rod 2 is fixedly installed on the upper surface of the chassis 1. A support rod 3 is slidably installed inside the hollow rod 2. A fixing frame 4 is fixedly installed at one end of the support rod 3. A support component 5 is installed on the fixing frame 4. A lifting component 7 is installed on the hollow rod 2 and the chassis 1. By setting the support component 5 and the lifting component 7, the support component 5 can support a single ventilation duct 20 or two ventilation ducts 20 during the docking process, which facilitates the construction personnel to assemble the ventilation ducts 20, improves the convenience of the ventilation duct 20 assembly construction, improves the efficiency of the ventilation duct 20 assembly construction, avoids safety accidents caused by the ventilation ducts 20 falling due to lack of support, and reduces the risk factor of the ventilation duct 20 assembly construction. The lifting component 7 can adjust the height of the support component 5, thereby meeting the assembly construction of ventilation ducts 20 at different heights.

[0027] The support assembly 5 includes a U-shaped bracket 51. When the ventilation duct 20 is located inside the U-shaped bracket 51, it provides support. Several reinforcing rods 52 are fixedly installed on the lower surface of the U-shaped bracket 51. One end of each reinforcing rod 52 is fixedly connected to one side of the fixing frame 4. These reinforcing rods 52 strengthen the U-shaped bracket 51 and improve its stability. Two limiting plates 53 are slidably installed inside the U-shaped bracket 51. Gaskets 54 are fixedly installed on opposite sides of each limiting plate 53. When the two limiting plates 53 approach each other, they limit the ventilation duct 20, improving its stability during support. Two movable seats 55 are slidably installed on the lower surface of the U-shaped bracket 51. The movable seats 55 are located below the limiting plates 53. Two... Guide blocks 6 are fixedly installed at the bottom of each guide groove 59 and each of the two limiting plates 53. The guide blocks 6 are slidably installed on the inner wall of the guide groove 59. By setting the guide groove 59 and the guide blocks 6, the guide blocks 6 can slide horizontally along the inner wall of the guide groove 59, thereby guiding the moving seat 55 and the limiting plate 53 in the horizontal direction, so that the moving seat 55 and the limiting plate 53 can move horizontally. When the moving seat 55 moves horizontally, the moving seat 55 can move the limiting plate 53 horizontally through the guide blocks 6. Two fixing plates 56 are fixedly installed on the lower surface of the U-shaped bracket 51. A double-ended screw 57 is rotatably installed between the two fixing plates 56. The double-ended screw 57 is threadedly rotatably connected to the two moving seats 55. A handle 58 is fixedly installed at one end of the double-ended screw 57. By manually rotating the handle 58, the handle 58 can rotate the double-ended screw 57, and the double-ended screw 57 can drive the two moving seats 55 to move towards each other or away from each other.

[0028] The lifting assembly 7 includes a lifting plate 71, a hollow rod 2 with a plurality of slots 72, a plurality of blocks 73 fixedly disposed on the inner wall of the lifting plate 71, the blocks 73 being slidably disposed on the inner wall of the slots 72, and the other end of the support rod 3 being fixedly disposed between the blocks 73. By driving the lifting plate 71 to rise and fall vertically, the lifting plate 71 can make the blocks 73 slide vertically in the slots 72, the blocks 73 can make the support rod 3 slide vertically in the hollow rod 2, and the support rod 3 can make the U-shaped bracket 51 rise and fall vertically through the fixing frame 4.

[0029] A drive motor 74 is fixedly mounted on the upper surface of the chassis 1. A lead screw 75 is fixedly mounted on the drive output end of the drive motor 74. The lead screw 75 passes through the lifting plate 71 and is threadedly connected to the lifting plate 71. A support plate 76 is fixedly mounted on one end of the hollow rod 2. One end of the lead screw 75 is rotatably mounted on the support plate 76. By starting the drive motor 74, the drive shaft of the drive motor 74 can make the lead screw 75 rotate, and the lead screw 75 can drive the lifting plate 71 to rise and fall vertically.

[0030] Working principle: During the assembly and construction of ventilation duct 20, after ventilation duct 20 is hoisted to the top of the wall, according to the assembly height of ventilation duct 20, the construction personnel place this protective bracket below ventilation duct 20, start the drive motor 74, the drive shaft of drive motor 74 causes lead screw 75 to rotate, lead screw 75 drives lifting plate 71 to rise and fall vertically, lifting plate 71 causes support rod 3 to rise and fall vertically in hollow rod 2 through locking block 73, support rod 3 causes U-shaped bracket 51 to rise and fall vertically synchronously through fixed frame 4, so that the bottom wall of U-shaped bracket 51 contacts the lower end face of ventilation duct 20. At this time, U-shaped bracket 51 supports ventilation duct 20;

[0031] Subsequently, the construction workers manually rotate the handle 58, which causes the double-headed screw 57 to rotate. The double-headed screw 57 drives the two moving seats 55 to move towards each other. The two moving seats 55 move the two limiting plates 53 towards each other through the corresponding guide blocks 6 until the gaskets 54 on the opposite sides of the two limiting plates 53 contact the side of the ventilation duct 20. Then, the rotation of the handle 58 is stopped. At this time, the U-shaped bracket 51 supports the ventilation duct 20, and the two limiting plates 53 limit the ventilation duct 20, allowing the construction workers to assemble the ventilation duct 20.

[0032] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
