Description

Technical Field

[0001] This utility model belongs to the technical field of construction auxiliary devices, and in particular relates to a limiting device for temporary column construction. Background Technology

[0002] A temporary column construction limiting device is an auxiliary device specifically designed for temporary column construction. This device aims to solve many problems caused by welding in existing column limiting methods. It is usually composed of specific structural components and can temporarily fix the column in a more convenient, efficient and less structurally damaging way. This limiting device does not require complicated welding operations and can quickly and accurately limit the column during installation, saving time and effort, reducing construction difficulty and cost. When disassembly is required later, it can also be easily carried out without special tools or destructive operations, which greatly improves work efficiency and protects the integrity of the column and surrounding structure. It is widely applicable to various temporary column construction scenarios.

[0003] Existing limiting devices use welding to temporarily fix the columns, but this method has significant drawbacks. First, welding is extremely complex and time-consuming, requiring specialized technicians to ensure quality and stability, which greatly increases construction difficulty and cost. Second, disassembly is difficult due to the high weld strength, often necessitating special tools and equipment, and potentially even destructive operations such as cutting the welded area. This not only damages the column and surrounding structure but also makes disassembly extremely cumbersome and time-consuming. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting device for temporary column construction. By setting up a connecting mechanism, it solves the problems of the extremely complex welding operation itself, which requires a lot of time and effort. Welding must be carried out by professional technicians, and the welding quality and stability must be ensured. This undoubtedly greatly increases the difficulty and cost of construction. Secondly, if it needs to be disassembled later, the welded connection method will bring great difficulties to the disassembly work. Due to the high welding strength, special tools and equipment are often required during the disassembly process, and even destructive operations such as cutting the welded parts may be necessary. As a result, not only will the column and surrounding structure be damaged to a certain extent, but the disassembly process will also be extremely cumbersome, consuming a lot of time and manpower.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a limiting device for temporary column construction, including a fixed sleeve, on which a connecting mechanism and a configuration mechanism are provided;

[0007] The connecting mechanism includes two sliding rods fixedly connected to the front of the fixed sleeve. A movable sleeve is slidably fitted onto the outer wall of the two sliding rods. A limiting sliding rod is slidably fitted onto the outer wall of the two sliding rods. A spring is wound around the outer wall of each of the two sliding rods. One end of each spring contacts the fixed sleeve, and the other end of each spring contacts the movable sleeve. A threaded rod is fixedly connected to the outer wall of the movable sleeve. The threaded rod passes through the limiting sliding rod and is slidably connected to it. A turntable is threaded onto the outer wall of the threaded rod. The turntable contacts the limiting sliding rod. A cylinder is provided on the inner wall of both the fixed sleeve and the movable sleeve.

[0008] Furthermore, the configuration mechanism includes two sleeves fixedly connected to the outer wall of the movable sleeve, and toothed rods are slidably fitted on the inner walls of the two sleeves, with ground nails fixedly connected to the bottom ends of the two toothed rods.

[0009] Furthermore, a strip rod is fixedly connected to the outer wall of the movable sleeve, and two U-shaped frames are fixedly connected to the outer wall of the movable sleeve. A rotating shaft is rotatably connected to each of the two U-shaped frames, and the two rotating shafts pass through the two U-shaped frames and the strip rod and are rotatably connected to the two U-shaped frames and the rotating shaft.

[0010] Furthermore, gears are fixedly fitted on the outer walls of both of the two rotating shafts, and both gears mesh with two racks.

[0011] Furthermore, a motor is fixedly connected to the outer wall of the movable sleeve, and a second rotating shaft is fixedly connected to the output end of the motor. Pulleys are fixedly fitted on the outer walls of the two rotating shafts and the second rotating shaft, and belts are wound around the outer walls of the several pulleys.

[0012] Furthermore, a U-shaped frame two is fixedly connected to the outer wall of the movable sleeve, a rotating block is rotatably connected to the inner wall of the U-shaped frame two, and a telescopic rod is fixedly connected to the bottom of the rotating block.

[0013] Furthermore, the bottom end of the telescopic rod is fixedly connected to a support leg, and a ground nail is slidably connected to the support leg.

[0014] This utility model has the following beneficial effects:

[0015] (1) By setting up a connecting mechanism, when in use, the fixed sleeve and the movable sleeve are first fitted onto the outer wall of the cylinder. Then, the turntable on the outer wall of the threaded rod is rotated, which causes the threaded rod to retract the limiting slide rod on the outer wall of the two slide rods. During the retraction of the limiting slide rod, the springs on the outer walls of the two slide rods are squeezed, thereby pushing the movable sleeve closer to the fixed sleeve. In this process, the compression of the movable sleeve by the spring creates a certain buffer space for the cylinder between the movable sleeve and the fixed sleeve. This setting helps to reduce the cumbersome process of installation and disassembly, thereby improving the installation efficiency.

[0016] (2) This utility model sets up a configuration mechanism to place the cylinder into the pre-embedded hole. After placement, the motor is started and the motor will drive the second rotating shaft to rotate. At the same time, when the second rotating shaft rotates, it will cooperate with multiple pulleys and belts, so that the two first rotating shafts can rotate synchronously with the second rotating shaft. At the same time, when the two first rotating shafts rotate, they will drive the gears on them to mesh with the two racks, so that the two racks can drive the ground nails on them to be inserted into the soil. This can temporarily fix the cylinder. This setting is conducive to quickly achieving the positioning and initial fixation of the cylinder, providing a stable foundation for subsequent reinforcement.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The connecting mechanism 2 includes two sliding rods 21 fixedly connected to the front of the fixed sleeve 1. A movable sleeve 22 is slidably fitted onto the outer wall of each sliding rod 21. A limiting sliding rod 23 is slidably fitted onto the outer wall of each sliding rod 21. Springs 24 are wound around the outer wall of each sliding rod 21. One end of each spring 24 contacts the fixed sleeve 1, and the other end contacts the movable sleeve 22. A threaded rod 25 is fixedly connected to the outer wall of the movable sleeve 22. The threaded rod 25 passes through the limiting sliding rod 23 and is slidably connected to it. A turntable 26 is threaded onto the outer wall of the threaded rod 25 and contacts the limiting sliding rod 23. Cylindrical sections 27 are provided on the inner walls of both the fixed sleeve 1 and the movable sleeve 22. By setting up a connecting mechanism, during use, the fixed sleeve 1 and the movable sleeve 22 are first fitted onto the outer wall of the cylinder 27. Then, the turntable 26 on the outer wall of the threaded rod 25 is rotated, causing the threaded rod 25 to retract the limiting slide rod 23 on the outer wall of the two slide rods 21. During the retraction of the limiting slide rod 23, the spring 24 on the outer wall of the two slide rods 21 is compressed, thereby pushing the movable sleeve 22 closer to the fixed sleeve 1. In this process, the compression of the movable sleeve 22 by the spring 24 creates a certain buffer space between the movable sleeve 22 and the fixed sleeve 1 for the cylinder 27. This setting helps to reduce the cumbersome process of installation and disassembly, thereby improving installation efficiency.

[0029] Configuration mechanism 3 includes two sleeves 31 fixedly connected to the outer wall of movable sleeve 22. A toothed rod 32 is slidably fitted onto the inner wall of each sleeve 31. A ground nail 33 is fixedly connected to the bottom end of each toothed rod 32. A strip rod 34 is fixedly connected to the outer wall of movable sleeve 22. Two U-shaped frames 35 are fixedly connected to the outer wall of movable sleeve 22. A rotating shaft 36 is rotatably connected to each of the two U-shaped frames 35. Both rotating shafts 36 pass through the two U-shaped frames 35 and the strip rod 34 and are respectively connected to... Two U-shaped frames 35 and a rotating shaft 36 are rotatably connected. Gears 37 are fixedly fitted onto the outer walls of both rotating shafts 36, and each gear 37 meshes with a rack 32. A motor 38 is fixedly connected to the outer wall of the movable sleeve 22. A rotating shaft 39 is fixedly connected to the output end of the motor 38. Pulleys 391 are fixedly fitted onto the outer walls of both rotating shafts 36 and 39. A belt 392 is wound around the outer wall of several pulleys 391. A belt 392 is fixedly connected to the outer wall of the movable sleeve 22. U-shaped frame 393 has a rotating block 394 rotatably connected to its inner wall. A telescopic rod 395 is fixedly connected to the bottom of the rotating block 394, and a support leg 396 is fixedly connected to the bottom end of the telescopic rod 395. A ground nail 397 is slidably connected to the support leg 396. By setting up a configuration mechanism, the cylinder 27 is placed into the pre-embedded hole. After placement, the motor 38 is started, which drives the rotating shaft 39 to rotate. Simultaneously, as the rotating shaft 39 rotates, it passes through multiple pulleys... The cooperation of 391 and belt 392 enables the two rotating shafts 36 to rotate synchronously with the rotating shaft 39. At the same time, when the two rotating shafts 36 rotate, they will drive the gears 37 on them to mesh with the two racks 32, so that the two racks 32 can drive the ground nails 33 on them to be inserted into the soil. This can temporarily fix the cylinder 27. This setting is conducive to quickly positioning and initially fixing the cylinder, providing a stable foundation for further reinforcement.

[0030] A specific application of this embodiment is as follows: In use, firstly, the fixed sleeve 1 and the movable sleeve 22 are fitted onto the outer wall of the cylinder 27. Then, the turntable 26 on the outer wall of the threaded rod 25 is rotated, causing the threaded rod 25 to retract the limiting slide rods 23 on the outer walls of the two slide rods 21. During the retraction of the limiting slide rods 23, the springs 24 on the outer walls of the two slide rods 21 are compressed, thereby pushing the movable sleeve 22 closer to the fixed sleeve 1. In this process, the compression of the movable sleeve 22 by the springs 24 creates a certain buffer space for the cylinder 27 between the movable sleeve 22 and the fixed sleeve 1. This setting helps to reduce the cumbersome process of installation and disassembly, thereby improving installation efficiency. Next, the cylinder 27 is placed into the pre-embedded hole. After placement, the motor is started. 38. Motor 38 drives shaft 2 39 to rotate. Simultaneously, as shaft 2 39 rotates, multiple pulleys 391 and belt 392 work together to make the two shafts 1 36 rotate synchronously with shaft 2 39. At the same time, the rotation of the two shafts 1 36 drives the gears 37 on them to mesh with the two racks 32, so that the two racks 32 can drive the ground nails 33 on them to be inserted into the soil. This can temporarily fix the cylinder 27. This setting is conducive to quickly positioning and initially fixing the cylinder, providing a stable foundation for further fixing. When it is necessary to reinforce the cylinder 27, the telescopic rod 395 can be pulled outward. The telescopic rod 395 will work with the support leg 396 and the ground nail 2 397 to reinforce the cylinder 27.
