Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a building bolt removal device. Background Technology

[0002] Bolts are very common in construction. Sometimes the nuts of bolts used in construction may come off due to accidents. In daily use, the tightening of bolts depends on the cooperation of the bolt nut and the tool. For bolts without nuts, the existing operating tools are difficult to remove, which makes it difficult to replace bolts. Therefore, a construction bolt removal device is needed to meet the needs. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a building bolt removal device, including a fixed frame, on which a cutting and grinding mechanism and an electric telescopic rod are fixed. A first motor is fixed on the electric telescopic rod, and a fixed plate is fixed on the top of the output shaft of the first motor. Two clamping assemblies are symmetrically arranged on the fixed plate. Each clamping assembly includes a threaded hole, which is located on the fixed plate. A threaded rod is inserted into the threaded hole, and a connecting rod is fitted and rotatably mounted on the threaded rod outside the threaded hole. A clamping rod is fixed on the connecting rod.

[0006] Preferably, the connecting rod has an L-shaped structure.

[0007] Preferably, a ring is fixed on the end of the threaded rod away from the threaded hole.

[0008] Preferably, the cutting and grinding mechanism includes a first protective box, which is fixed on the fixed frame. A second protective box is fixed on the first protective box. Two grinding wheels are symmetrically arranged in the second protective box. Each grinding wheel has a rotating shaft fixed coaxially. A driving mechanism is fixed on both rotating shafts. The driving mechanism is fixed on the first protective box.

[0009] Preferably, each of the rotating shafts and the second protective box is provided with a support assembly.

[0010] Preferably, the support assembly includes a limiting ring, which is rotatably mounted on the rotating shaft, and a fixing rod is fixed on the limiting ring and fixed to the second protective box.

[0011] Preferably, the drive mechanism includes a second motor, which is fixed to the first protective box. A first gear is fixed to the top of the output shaft of the second motor. Two second gears mesh with the first gear. Both rotating shafts pass through the second protective box and are respectively fixed to the two second gears. Both rotating shafts and the second protective box are rotatably connected.

[0012] The present invention discloses a bolt removal device for buildings, which has the following advantages: When in use, the bolt removal device uses a cutting and grinding mechanism to grind two symmetrical cuts on the bolt that is missing a nut. Two clamping rods are inserted into the two cuts on the bolt that is missing a nut.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 2 and 3 A bolt removal device for construction includes a fixed frame 1, on which a cutting and grinding mechanism and an electric telescopic rod 2 are fixed. The cutting and grinding mechanism grinds two symmetrical cuts on the bolt lacking a nut. A first motor 3 is fixed on the electric telescopic rod 2. A fixed plate 4 is fixed on the top of the output shaft of the first motor 3. Two clamping components are symmetrically arranged on the fixed plate 4. The two clamping components correspond to the two cuts ground on the bolt lacking a nut. By cooperating with the two clamping components and the two cuts, the bolt lacking a nut can be firmly clamped.

[0022] The clamping assembly includes a threaded hole 7, which is located on the fixed plate 4. A threaded rod 8 is inserted into the threaded hole 7. A ring 9 is fixed to the end of the threaded rod 8 away from the threaded hole 7. The ring 9 facilitates the turning of the threaded rod 8. A connecting rod 5 is fitted and rotatably mounted on the threaded rod 8 outside the threaded hole 7. The connecting rod 5 is located between the ring 9 and the fixed plate 4. The connecting rod 5 has an L-shaped structure. A clamping rod 6 is fixed on the connecting rod 5. Two clamping rods 6 are located between two connecting rods 5, and the two clamping rods 6 correspond to two cuts ground on the bolts that lack nuts.

[0023] In use, the cutting and grinding mechanism grinds two symmetrical notches into the bolt lacking a nut. The two rings 9 are then turned, causing them to rotate the two threaded rods 8 in the two threaded holes 7. Simultaneously, the two connecting rods 5 move towards each other until the two clamping rods 6 are inserted into the two notches on the bolt. The clamping rods 6 and the two notches work together to hold the bolt lacking a nut. Then, the first motor 3 and the electric telescopic rod 2 are activated. The two connecting rods 5 and the two clamping rods 6 rotate and move the bolt lacking a nut upwards, allowing it to be removed from the building for easy replacement.

[0024] Example 2: Based on Example 1, refer to Figure 2-6As another preferred embodiment of this utility model, the difference from embodiment 1 is that the cutting and grinding mechanism includes a first protective box 10, which is fixed on the fixing frame 1. A second protective box 11 is fixed on the first protective box 10. Two grinding wheels 16 are symmetrically arranged in the second protective box 11. A rotating shaft 15 is coaxially fixed on each grinding wheel 16. A driving mechanism is fixed on both rotating shafts 15. The driving mechanism is fixed on the first protective box 10. The driving mechanism drives the two grinding wheels 16 at the same time. The two grinding wheels 16 alternately grind the two sides of the bolt without a nut, thereby grinding two symmetrical cuts on the bolt without a nut.

[0025] Each rotating shaft 15 and the second protective box 11 is provided with a support assembly. The support assembly includes a limiting ring 17, which is rotatably mounted on the rotating shaft 15. A fixing rod 18 is fixed on the limiting ring 17 and fixed on the second protective box 11. The limiting ring 17 and the fixing rod 18 are used to support the rotating shaft 15 without affecting the rotation of the rotating shaft 15.

[0026] The drive mechanism includes a second motor 12, which is fixed to the first protective box 10. A first gear 13 is fixed to the top of the output shaft of the second motor 12. Two second gears 14 mesh with the first gear 13. Two rotating shafts 15 pass through the second protective box 11 and are fixed to the two second gears 14 respectively. The two rotating shafts 15 and the second protective box 11 are rotatably connected. The second motor 12 drives the two rotating shafts 15 to rotate simultaneously through the cooperation of the first gear 13 and the two second gears 14.

[0027] In use, the bolt missing its nut is inserted between the two grinding wheels 16 in the second protective box 11. The second motor 12 is started, and the second motor 12 drives the two rotating shafts 15 to rotate simultaneously through the first gear 13 and two second gears 14. The two rotating shafts 15 drive the two grinding wheels 16 to rotate, reciprocating the first protective box 10 and the second protective box 11, so that the two grinding wheels 16 alternately contact the two sides of the bolt missing its nut, thereby processing two symmetrical cuts on the bolt missing its nut. When processing the cuts, the second protective box 11 can prevent the waste generated during processing from flying, ensuring safety during use. After the symmetrical cuts on the bolt missing its nut are processed, the bolt missing its nut is tightened on the building using the two clamping rods 6.

[0028] 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.
