[0021] 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.

[0022] Please see Figure 1-8 This utility model provides a technical solution:

[0023] like Figure 1 As shown, to improve the flexibility of pipe fixing and the stability of base 1, a BIM-based green building fire protection construction pipe pre-embedded installation device is proposed. Base 1 is fixedly equipped with a ground-mounted rod 101 and also includes a support frame 202, a wedge block 203, and a chuck 305. The support frame 202 is provided on the upper surface of base 1. The inner side of the support frame 202 contacts and connects with one side of the wedge block 203. The wedge block 203 is slidably mounted on a second connecting rod 207. The second connecting rod 207 is threadedly connected to a first screw 209. Pipe fixing is achieved by moving the wedge block 203 and the support frame 202. The first screw 209... The first screw 209 is rotatably mounted on the base 1. One end of the first screw 209 is fixedly connected to the first bevel gear 301. The first bevel gear 301 meshes with the second bevel gear 302. The second bevel gear 302 is fixedly mounted on the surface of the double-ended threaded sleeve 303. The double-ended threaded sleeve 303 is rotatably mounted inside the base 1. The two ends of the double-ended threaded sleeve 303 are respectively threaded to the second screw 304. The threads on the two second screws 304 are in opposite directions. The end of the second screw 304 away from the double-ended threaded sleeve 303 is fixedly connected to the chuck 305. The chuck 305 is slidably mounted inside the base 1. The stability of the base 1 is improved by the chuck 305.

[0024] The base 1 has a threaded plate 102 on its surface that clamps the first screw 209. A fixing screw is screwed into the threaded plate 102, and the threaded plate 102 and fixing screw clamp the first screw 209, locking it and preventing free rotation (shown in...). Figure 5 ).

[0025] like Figure 2-4As shown, one end of the first connecting rod 201 is fixedly connected to the upper surface of the base 1, and the other end of the first connecting rod 201 is fixedly connected to the support frame 202. The support frame 202 is semi-circular, and the inner side of the support frame 202 is set as an inclined surface. The inner side of the support frame 202 contacts and connects with one side of the wedge block 203. The wedge block 203 is fixedly connected to one end of the sliding rod 204, and the other end of the sliding rod 204 passes through the driven rod 205 and is slidably connected to the driven rod 205. The end of the sliding rod 204 passing through the driven rod 205 is fixedly connected to... One end of the first spring 206 is fixedly connected to the driven rod 205, and the other end of the first spring 206 is fixedly connected to the driven rod 205. The driven rod 205 is fixedly connected to the second connecting rod 207. The second connecting rod 207 is slidably installed in the base 1. A threaded ring 208 is fixedly installed in the middle of the second connecting rod 207. The threaded ring 208 is threadedly connected to the first screw 209. The first screw 209 is rotatably installed in the base 1. The pipe is fixed by the wedge block 203 and the support frame 202. The wedge block 203 and related components are in two sets.

[0026] The base 1 is placed in the pre-buried pit, and the grounding rod 101 is inserted into the soil to achieve initial fixation of the base 1. Then, one end of the pipe is placed on the support frame 202, which provides initial support for the pipe. The initial placement of the pipe is achieved through the two bases 1. After the pipe is placed on the support frame 202, the first screw 209 is turned. The first screw 209 rotates within the base 1, causing the threaded ring 208 to move closer to the support frame 202. The threaded ring 208 is fixedly connected to the second connecting rod 207, so the second connecting rod 207 and the driven rod 205 will move in the same direction. The driven rod 205 causes the wedge block 203 to move closer to the support frame 202. As the inclined plane gradually comes into contact with the inner side of the support frame 202, the wedge block 203 will be resisted by the inner side of the support frame 202. Therefore, as the driven rod 205 moves, the wedge block 203 will drive the sliding rod 204 to slide on the driven rod 205. The first spring 206 is gradually compressed. As the driven rod 205 moves, after the straight edge of the wedge block 203 comes into contact with the pipe surface, the pipe is subjected to the squeezing force of the two wedge blocks 203, thereby clamping the pipe. The movement distance of the wedge block 203 can adapt to fire pipes of different diameters. A shorter movement distance of the wedge block 203 corresponds to a larger diameter pipe, and a longer movement distance of the wedge block 203 corresponds to a smaller diameter pipe.

[0027] One end of the first screw 209 is fixedly connected to the first bevel gear 301. The first bevel gear 301 meshes with the second bevel gear 302. The second bevel gear 302 is fixedly installed on the surface of the double-ended threaded sleeve 303. The double-ended threaded sleeve 303 is rotatably installed in the base 1. The two ends of the double-ended threaded sleeve 303 are respectively threaded to the second screw 304. The threads on the two second screws 304 are in opposite directions. The end of the second screw 304 away from the double-ended threaded sleeve 303 is fixedly connected to the chuck 305. The chuck 305 is slidably installed in the base 1. The chuck 305 is provided with a chuck hole 306.

[0028] As the first screw 209 rotates, it drives the first bevel gear 301 to rotate. The first bevel gear 301 meshes with the second bevel gear 302, and the second bevel gear 302 rotates. The second bevel gear 302 drives the double-ended threaded sleeve 303 to rotate. The double-ended threaded sleeve 303 rotates in place, and the two second screws 304 connected to it by threads move in opposite directions. The two second screws 304 push the chuck 305 out of the base 1.

[0029] like Figure 5-7 As shown, a toothed plate 401 is slidably installed inside the base 1. A rack 402 is fixedly installed on the inner wall of the toothed plate 401. The toothed plate 401 is connected to the first gear 403 through meshing with the rack 402. The first gear 403 is fixedly installed on the surface of the rotating rod 404. The rotating rod 404 is splinedly connected to the spline sleeve 405. The spline sleeve 405 is rotatably installed inside the base 1. One side of the spline sleeve 405 is fixedly connected to one end of the second spring 406. The second spring 406 is sleeved on the rotating rod 404. The other end of the second spring 406 is fixedly connected to the rotating rod 404. The other end of the rotating rod 404 is in contact with the upper surface of the turntable 407. The turntable 407 rotates and is installed... Mounted on the upper end of base 408, base 408 is longitudinally slidably installed in base 1, bracket 409 is fixedly connected to the outer wall of base 408, and a locking tooth 410 is fixedly connected to the upper surface of bracket 409. The locking tooth 410 is in contact with the locking tooth strip 411 on the lower surface of tooth plate 401. The locking tooth strip 411 is fixedly set on the lower surface of tooth plate 401. One end of third spring 412 is fixedly connected to the lower surface of bracket 409. The other end of third spring 412 is fixedly connected to the inside of base 1. Connecting plate 413 is fixedly connected to one side of tooth plate 401. One end of support rod 414 is hinged to the lower surface of connecting plate 413. One end of connecting plate 413 is fixedly connected to contact plate 415.

[0030] After the chuck 305 is pushed out of the base 1, the rotating rod 404 is manually pressed down. The rotating rod 404 slides down inside the spline sleeve 405. The spline sleeve 405 does not move. The second spring 406 is compressed and shortened. The rotating rod 404 continues to move down. The first gear 403 on the surface of the rotating rod 404 meshes with the rack 402 on the gear plate 401. At the same time, the lower end of the rotating rod 404 contacts the upper surface of the turntable 407 on the base 408. The base 408 is subjected to pressure from the rotating rod 404. The base 408 moves down and drives the bracket 409 to move in the same direction. The locking teeth 410 on the upper surface of the bracket 409 are disconnected from the locking rack 411 on the lower surface of the gear plate 401. The gear plate 401 is no longer restricted. The third spring 412 on the lower surface of the bracket 409 is compressed and shortened.

[0031] Subsequently, by manually rotating the rotating rod 404, the spline sleeve 405 and the second spring 406 rotate simultaneously. The first gear 403 on the rotating rod 404 drives the toothed plate 401 to move outside the base 1. At the same time, the rotating rod 404 drives the turntable 407 to rotate. Since the turntable 407 is rotatably mounted on the base 408, the base 408 and related supports 409 do not rotate. When the contact plate 415 on the toothed plate 401 contacts the pit wall, the rotating rod 404 is released, the second spring 406 loses pressure and reverts to its original position. When the second spring 406 pushes the rotating rod 404 upward, the first gear 403 is disconnected from the rack 402. After the rotating rod 404 moves upward, the turntable 407 is disconnected from the rotating rod 404. After the base 408 loses the pressure from the rotating rod 404, the third spring 412 returns to its original state and pushes the base 408 upward until the locking teeth 410 on the upper surface of the bracket 409 are engaged in the locking rack 411 on the lower surface of the toothed plate 401. The locking teeth 410 and the locking rack 411 can lock the toothed plate 401.

[0032] After pushing the toothed plate 401 out of the base 1 and loosening the rotating rod 404, rotate the support rod 414 on the lower surface of the connecting plate 413 out, insert one end of the support rod 414 into the chuck hole 306 on the chuck 305, and fix the support rod 414 with bolts.

[0033] The toothed plate 401 and related mechanisms are in two sets, corresponding to two sets of chucks 305 respectively.

[0034] Working principle:

[0035] First, place the base 1 in the pre-buried pit and insert the ground rod 101 into the soil layer to achieve the initial fixation of the base 1;

[0036] After placing the pipe on the support frame 202, the first screw 209 is turned, causing the threaded ring 208 to move closer to the support frame 202. The second connecting rod 207 and the driven rod 205 will move in the same direction. The driven rod 205 drives the wedge block 203 to move closer to the support frame 202. The inclined surface of the wedge block 203 gradually contacts the inner side of the support frame 202. The pipe is squeezed by the two wedge blocks 203, thus clamping the pipe. The movement distance of the wedge block 203 can accommodate fire pipes of different diameters. A shorter movement distance of the wedge block 203 corresponds to a larger diameter pipe, and a longer movement distance of the wedge block 203 corresponds to a smaller diameter pipe.

[0037] As the first screw 209 rotates, it will drive the first bevel gear 301 to rotate, and the second bevel gear 302 will rotate. The second bevel gear 302 will drive the double-ended threaded sleeve 303 to rotate, and the two second screws 304 connected to it will move in opposite directions. The second screws 304 will push the chuck 305 out of the base 1.

[0038] After the chuck 305 is pushed out of the base 1, the rotating rod 404 is manually pressed down. The rotating rod 404 slides down inside the spline sleeve 405, the second spring 406 shortens, and the rotating rod 404 continues to move down. The first gear 403 on the surface of the rotating rod 404 meshes with the rack 402 on the gear plate 401. At the same time, the lower end of the rotating rod 404 contacts the upper surface of the turntable 407 on the base 408. The base 408 is subjected to pressure from the rotating rod 404. The base 408 moves down and drives the bracket 409 to move in the same direction. The locking teeth 410 on the upper surface of the bracket 409 are disconnected from the locking rack 411 on the lower surface of the gear plate 401. The gear plate 401 is no longer restricted, and the third spring 412 on the lower surface of the bracket 409 is compressed and shortened.

[0039] Subsequently, by manually rotating the rotating rod 404, the first gear 403 drives the toothed plate 401 to move outside the base 1. At the same time, the rotating rod 404 drives the turntable 407 to rotate. When the contact plate 415 on the toothed plate 401 contacts the pit wall, the rotating rod 404 is released, the second spring 406 loses pressure and resets, and the second spring 406 pushes the rotating rod 404 upward to move. The base 408 loses pressure from the rotating rod 404, the third spring 412 returns to its original state and pushes the base 408 upward until the locking teeth 410 on the upper surface of the bracket 409 engage with the locking rack 411 on the lower surface of the toothed plate 401. The locking teeth 410 and the locking rack 411 can lock the toothed plate 401.

[0040] After pushing the toothed plate 401 out of the base 1 and loosening the rotating rod 404, rotate the support rod 414 on the lower surface of the connecting plate 413 out, insert one end of the support rod 414 into the chuck hole 306 on the chuck 305, and fix the support rod 414 with bolts.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
