Description

Technical Field

[0001] The utility model relates to the technical field of chimney shock absorption, in particular to a hinge adjusting device for a pendulum chimney damper. Background Technique

[0002] A pendulum chimney damper is a device used to reduce the vibration of a chimney structure. It usually consists of components such as a damper and a connection structure. The working principle of the pendulum damper is to adjust the natural vibration frequency of the pendulum to be close to the control frequency of the main structure, so as to weaken or control the vibration of the main structure. It allows the pendulum body to swing under wind load or seismic action, thereby consuming energy and reducing the structural vibration.

[0003] For the connection components on the hinge adjusting device of the existing pendulum chimney damper, steel chains are usually used. The up and down position of the damper is adjusted by adjusting the length of the steel chain. However, most of the adjusting devices use two clamping plates. The steel chain is clamped between the two clamping plates, and bolts pass through the inside of the two clamping plates and the steel chain to limit the moving position of the steel chain. Although this adjustment method is feasible, the clamping plates will rotate with the bolts when tightened. The rotation of the clamping plates is not convenient for construction workers to rotate the bolts to tighten the two clamping plates, increasing the construction difficulty. To solve this technical problem, the utility model proposes a hinge adjusting device for a pendulum chimney damper. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a hinge adjusting device for a pendulum chimney damper, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A hinge adjusting device for a pendulum chimney damper includes a chimney body, a steel chain, and a damper body. A support frame is connected to the outer surface of the chimney body. One end of the support frame away from the chimney body is connected with a lifting lug. The steel chain passes through the inside of the lifting lug, and one end of the steel chain folds back downward. The damper body is connected to one end of the steel chain. Two clamping plates are arranged outside the steel chain at the folded-back part. Bolts are connected through the inner sides of the two clamping plates. At the same time, the bolts pass through two connecting rings of the steel chain. A nut is threadedly connected to one end of the bolt outside one of the clamping plates. A positioning mechanism is arranged outside the clamping plates. A positioning insertion rod is connected to one side of one of the clamping plates, and a positioning hole is opened in the inner side of the other clamping plate. The outer surface of the positioning insertion rod is in contact with the inner wall of the positioning hole.

[0007] Preferably, a hexagonal card seat is connected to one side of the other clamping plate, and the inner wall of the hexagonal card seat is in contact with the hexagonal head of the bolt.

[0008] Preferably, the positioning mechanism includes a base, the base is connected to one side of one of the clamping plates, a guide rod is slidably connected to the inner wall of the base, and a first chuck is connected to the end of the guide rod located outside the base.

[0009] Preferably, a first spring is sleeved on the outer portion of the guide rod, one end of the first spring is connected to one side of the first chuck, and the other end of the first spring is connected to one side of the base.

[0011] Preferably, a support plate is connected to the outer surface of the chimney body, one side of the support plate is connected to a second spring, and the other end of the second spring is connected to one side of the damper body.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] In the present utility model, through the cooperation between the positioning clamping plates, the insertion rods and the positioning holes, while the two clamping plates form a sandwich on the steel chain, the positioning insertion rod penetrates and inserts into the positioning hole. The positioning hole restricts the shaking of the positioning insertion rod to maintain the stability of the clamping plate. By the contact between the positioning insertion rod and the positioning hole, the two clamping plates restrict each other's movement, making the clamping plate stable when the nut is rotated, reducing the construction difficulty and facilitating the installation of the clamping plate.

[0014] In the present utility model, through the cooperation between the first chuck, the second chuck and the first spring, after the nut is tightened, the first spring pushes the first chuck to tightly contact the second chuck, reducing the self-rotation of the nut caused by the vibration of the chimney body and improving the stability of the nut.

Detailed implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with the detailed implementation mode.

[0022] As Figures 1-5 shown, a hinge adjustment device for a pendulum chimney damper includes a chimney body 1, a steel chain 2 and a damper body 3. A support frame 4 is connected to the outer surface of the chimney body 1, and a lifting lug 5 is connected to one end of the support frame 4 away from the chimney body 1. The stability of the lifting lug 5 is maintained by the support frame 4. The steel chain 2 passes through the inside of the lifting lug 5, and one end of the steel chain 2 is folded back downward. The damper body 3 is connected to one end of the steel chain 2. Two clamping plates 6 are arranged outside the folded-back part of the steel chain 2. A bolt 7 is connected through the inner sides of the two clamping plates 6. At the same time, the bolt 7 passes through two connecting rings of the steel chain 2. One end of the bolt 7 outside one of the clamping plates 6 is threadedly connected with a nut 8. By rotating the nut 8, the distance between the two clamping plates 6 is reduced, so that the two clamping plates 6 clamp the steel chain 2 to maintain the stability of the steel chain 2.

[0023] One side of one of the clamping plates 6 is connected with a positioning plug rod 10, and a positioning hole 11 is opened on the inner side of the other clamping plate 6. The outer surface of the positioning plug rod 10 is in contact with the inner wall of the positioning hole 11. By inserting the positioning plug rod 10 into the positioning hole 11, the two clamping plates 6 are restricted from moving relative to each other, so that the clamping plates 6 have stability when the nut 8 is rotated.

[0024] One side of the other clamping plate 6 is connected with a hexagonal chuck 12, and the inner wall of the hexagonal chuck 12 is in contact with the hexagonal head of the bolt 7. By wrapping the hexagonal head of the bolt 7 inside the hexagonal chuck 12, the stability of the bolt 7 is maintained when the nut 8 is rotated.

[0025] A positioning mechanism 9 is provided on the outside of the splint 6, and the stability of the nut 8 is maintained by the positioning mechanism 9. The positioning mechanism 9 includes a base 901, and the base 901 is connected to one side of one of the splints 6. The inner wall of the base 901 is slidably connected to a guide rod 902, and one end of the guide rod 902 located outside the base 901 is connected to a chuck 1 904, and the rotation of the chuck 1 904 is limited by the guide rod 902, so that the chuck 1 904 has only a forward and backward sliding motion trajectory. At the same time, the guide rod 902 can maintain the stability of the spring 2 14 during elastic contraction, and the outer side of the guide rod 902 is sleeved with a spring 1 905, and one end of the spring 1 905 is connected to the chuck 1 904. One side is connected, and the other end of spring one 905 is connected to one side of the base 901. Chuck one 904 maintains the contact force with chuck two 903 through the elastic support of spring one 905. Chuck two 903 is connected to one side of the nut 8. The outer surface of chuck two 903 is in contact with the outer surface of chuck one 904. Through the contact between chuck one 904 and chuck two 903, chuck one 904 forms resistance to chuck two 903, thereby improving the stability of the nut 8. When the chimney body 1 shakes, the nut 8 may be driven to rotate, causing the nut 8 to be out of contact with the bolt 7. The rotation of the nut 8 is limited by the misaligned contact between chuck one 904 and chuck two 903.

[0026] The outer surface of the chimney body 1 is connected to a support plate 13, one side of the support plate 13 is connected to a spring 14, the other end of the spring 14 is connected to one side of the damper body 3, the damper body 3 is elastically supported by the spring 14, when the damper body 3 moves, the spring 14 plays the function of elastic pulling on it, and drives the damper body 3 to reset.

[0027] It should be noted that, in actual use of the device, first, the steel chain 2 is passed through the lifting ear 5, and after measuring the length of the steel chain 2, the two clamps 6 are installed on the outside of the steel chain 2, and the positioning rod 10 is inserted into the positioning hole 11, and then the bolt 7 is passed through the two clamps 6, and then the nut 8 is rotated to shrink the distance between the two clamps 6. When the nut 8 rotates, the chuck 2 903 is driven to rotate at the same time. When the chuck 2 903 is in contact with the chuck 1 904, the chuck 2 903 pushes the chuck 1 904 to move backward. When the chuck 1 904 moves backward, the spring 1 905 is compressed. After the nut 8 is tightened, the spring pushes the chuck 1 904 to tightly contact the chuck 2 903.
