Detailed Embodiments

[0019] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides a special fixture for I-beam guides used in iron towers by making improvements. The technical solution of the present utility model is as follows:

[0021] As Figures 1 - 3 shown, a special fixture for I-beam guides used in iron towers includes an angle steel main material 1. A guide rail 2 is arranged outside the angle steel main material 1. A pressing plate 3 is arranged between the angle steel main material 1 and the guide rail 2. An adjusting hole 4 is formed in the side wall of the pressing plate 3. A foot nail 5 penetrating the side wall of the angle steel main material 1 is arranged inside the adjusting hole 4. Two fixing nuts 6 are threadedly installed on the side wall of the foot nail 5. The two fixing nuts 6 are respectively in close contact with the side walls of the pressing plate 3 and the angle steel main material 1. By passing the foot nail 5 through the adjusting hole 4 and the angle steel main material 1 and fixing the position of the foot nail 5 through the two fixing nuts 6, the position of the pressing plate 3 is fixed. Two clamping plates 7 are arranged outside the pressing plate 3. Clamping grooves are formed in the side walls of the two clamping plates 7 close to each other. One end of the two clamping plates 7 close to each other is clamped on the side wall of the guide rail 2. A pressing rod 10 slidably penetrates through the side wall of the clamping plate 7 far from the pressing plate 3. The cross section of the pressing rod 10 is in a "T" shape. A fixing screw 11 is slidably installed on the side wall of the clamping plate 7 close to the pressing plate 3. Connecting grooves 13 are formed in the side walls of the fixing screw 11 and the pressing rod 10 close to each other. Connecting balls 14 are rotatably installed inside the two connecting grooves 13. One end of the side walls of the two connecting balls 14 close to each other is fixedly installed with a connecting rod 15. A clamping nut 12 is threadedly installed on the side wall of the fixing screw 11. The clamping nut 12 is in contact with the side wall of the pressing plate 3 far from the clamping plate 7. By rotating the clamping nut 12, the fixing screw 11 moves away from the clamping plate 7. Through the connecting balls 14 and the connecting rod 15, the two clamping plates 7 approach each other. Therefore, the two clamping plates 7 can be tightly pressed on the side wall of the guide rail 2 to complete the installation, achieving the effect of convenient installation.

[0022] As Figures 1 - 3As shown, in one embodiment, in order to facilitate adaptation to guide rails 2 of different sizes, connecting hinges 8 are fixedly installed on the side walls of the two clamping plates 7 away from the guide rail 2; the two clamping plates 7 are rotatably installed together through the connecting hinges 8, and one end of the two clamping plates 7 is fixed. The pressure rod 10 is pulled closer to the pressing plate 3 through the fixing screw 11 and the clamping nut 12, reducing the possibility of the two clamping plates 7 crossing each other, enabling the two clamping plates 7 to clamp the guide rail 2 more tightly and ensuring the installation effect; in order to ensure the stable position of the clamping plate 7, positioning plates 9 are fixedly installed at both the upper and lower ends of the side wall of the clamping plate 7 close to the pressing plate 3, and the side wall surfaces of the two positioning plates 9 close to each other are attached to the side wall of the pressing plate 3; the position of the clamping plate 7 is positioned through the two positioning plates 9 to ensure the stable position of the clamping plate 7; in order to prevent the pressure rod 10 from rotating together with the clamping nut 12, a fixing hole 16 is formed in the side wall of the pressure rod 10; the staff restricts the position of the pressure rod 10 by inserting a wrench into the interior of the fixing hole 16 to prevent the pressure rod 10 from rotating together with the clamping nut 12; the end of the side wall surface of the two clamping plates 7 close to the guide rail 2 is arc-shaped; by setting the end of the clamping plate 7 close to the guide rail 2 to be arc-shaped, when the clamping plate 7 rotates around the connecting hinge 8, the side wall of the clamping plate 7 can still be attached to the side wall of the guide rail 2, facilitating the clamping of the two clamping plates 7 on the side wall of the guide rail 2.

[0023] The specific working method is as follows: The foot nail 5 is passed through the adjustment hole 4 and the angle steel main material 1, and the position of the foot nail 5 is fixed by two fixing nuts 6 to fix the position of the pressing plate 3; a wrench is inserted into the interior of the fixing hole 16 to restrict the position of the pressure rod 10, and then the clamping nut 12 is rotated to move the fixing screw 11 to the side away from the clamping plate 7. The two clamping plates 7 are brought closer to each other through the connecting ball 14 and the connecting rod 15, and the two clamping plates 7 can thus be tightly pressed against the side wall of the guide rail 2 to complete the installation, achieving the effect of convenient installation. The two clamping plates 7 are rotatably installed together through the connecting hinge 8, and one end of the two clamping plates 7 is fixed. The pressure rod 10 is pulled closer to the pressing plate 3 through the fixing screw 11 and the clamping nut 12, reducing the possibility of the two clamping plates 7 crossing each other, enabling the two clamping plates 7 to clamp the guide rail 2 more tightly and ensuring the installation effect. The position of the clamping plate 7 is positioned through the two positioning plates 9 to ensure the stable position of the clamping plate 7.
