DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0024] See also Figures 1 to 4 In the utility model, an anti-tilt and reverse-pull device for an angle steel tower includes a connecting mechanism 200 installed on an angle steel tower 100, and a base 300 fixed on the ground, a traction mechanism 400 is installed on the base 300, a steel cable 500 is arranged between the connecting mechanism 200 and the traction mechanism 400, a fastening mechanism 600 and a driving mechanism 700 are arranged on the traction mechanism 400, and the driving mechanism 700 can be operated to lock the fastening mechanism 600 to the traction mechanism 400.

[0025] In this embodiment, preferably, the connection mechanism 200 includes an inner clamping plate 201 and an outer clamping plate 202 attached to the angle steel tower 100, the inner clamping plate 201 and the outer clamping plate 202 are locked by bolts, and a fixing ear 203 is fixedly provided on the side of the outer clamping plate 202;

[0026] Specifically, the inner clamping plate 201 and the outer clamping plate 202 are clamped on the angle steel tower 100 and locked, providing a fulcrum for preventing tilting and reverse pulling, replacing the method of drilling or welding connecting components, which is easy to use and will not adversely affect the mechanical properties of the angle steel tower 100 itself.

[0027] In this embodiment, preferably, the traction mechanism 400 includes two support plates 401 fixedly connected above the base 300 and spaced apart along the length direction of the base 300, a rotating shaft 402 is rotatably arranged between the two support plates 401, a winding roller 403 is fixedly arranged on the outer wall of the rotating shaft 402, and both ends of the steel cable 500 are respectively fixedly connected to the fixed ear 203 and the winding roller 403, both ends of the rotating shaft 402 pass through the support plate 401 and are fixedly provided with a flange 900, and the rotating shaft 402 can be connected to the winch motor through the flange 900.

[0028] Specifically, the steel cable 500 can be wound up by driving the winding roller 403 through the rotating shaft 402, so that the steel cable 500 pulls the angle steel tower 100 through the connecting mechanism 200 to prevent tilting;

[0029] The winch motor barrel flange 900 is connected to the rotating shaft 402. Since the winch motor drives the rotating shaft 402 to rotate, and since there are a large number of angle steel towers 100 and most of them are built in remote areas, it is unrealistic to equip each traction mechanism 400 with a winch motor. Therefore, a detachable method is adopted, and a winch motor can be connected when the rotating shaft 402 needs to be rotated.

[0030] In this embodiment, preferably, the fastening mechanism 600 is symmetrically arranged at both ends of the rotating shaft 402, and the fastening mechanism 600 includes a toothed disc 601 fixedly arranged on the outer wall of the rotating shaft 402 and a plurality of connecting rods 602 fixedly arranged on one side of the supporting plate 401, and connecting rings 603 are slidably arranged on the outer walls of the plurality of connecting rods 602, and an inner toothed ring 604 which is sleeved on the outer side of the toothed disc 601 and engaged with the toothed disc 601 is fixedly arranged between the plurality of connecting rings 603;

[0032] In this embodiment, preferably, the driving mechanism 700 includes a rotating rod 701 rotatably arranged between the two support plates 401, the two ends of the rotating rod 701 respectively pass through the two support plates 401 and are threadedly connected with nuts 702, the two nuts 702 are respectively fixedly connected with the two inner gear rings 604, a worm 703 is rotatably arranged on the base 300, and a worm wheel 704 meshing with the worm 703 is fixedly sleeved on the outer wall of the rotating rod 701;

[0033] The outer walls of both ends of the rotating rod 701 are provided with external threads, and the external threads at both ends of the rotating rod 701 are arranged in opposite directions. The rotating rod 701 is threadedly connected with the nut 702 through the external threads, and the ends of the rotating rod 701 and the connecting rod 602 are fixedly provided with limit blocks 800;

[0034] Specifically, the worm wheel 704 can be rotated by rotating the worm 703 , and the worm wheel 704 drives the rotating rod 701 to rotate. The rotation of the rotating rod 701 can move the nut 702 through thread transmission, and the nut 702 drives the inner gear ring 604 to move and engage with the toothed disc 601 .

[0035] In this embodiment, preferably, a notch 204 that engages with the angle steel tower 100 is provided on one side of the inner clamping plate 201 facing the angle steel tower 100, and inner buckles 205 are integrally formed at both ends of the outer clamping plate 202, and the inner buckles 205 clamp the inner clamping plate 201 on the inner side of the outer clamping plate 202;

[0036] Specifically, after the inner plate 201 and the outer plate 202 are connected to each other, the notch 204 of the inner plate 201 is stuck on the angle steel tower 100, and the inner buckle 205 of the outer plate 202 is buckled on the inner plate 201. When the steel cable 500 pulls the outer plate 202 through the fixing ear 203, the outer plate 202 is subjected to force and acts on the inner plate 201 through the inner buckle 205. Compared with the method of simply tightening with bolts, it is more secure and has a better force-bearing method.

[0037] The working principle and use process of this utility model:

[0038] The inner clamping plate 201 and the outer clamping plate 202 are clamped on the angle steel tower 100 and locked, the bottom plate is fixed at a designated position on the ground, the steel cable 500 is connected to the fixing ear 203 and the winding roller 403, and finally the hoisting motor is connected to the rotating shaft 402 through the flange 900. The hoisting motor drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the winding roller 403 to wind up the steel cable 500, and the angle steel tower 100 can be tightened and supported by the steel cable 500;

[0039] After the steel cable 500 is tightened, the worm 703 is rotated to drive the rotating rod 701 to rotate through the worm wheel 704, and the nuts 702 at both ends of the rotating rod 701 drive the inner gear ring 604 to move. The inner gear ring 604 moves linearly under the action of the connecting ring 603 and the connecting rod 602. The inner gear ring 604 can be clamped on the toothed disc 601 to fix the rotating shaft 402. At this time, the winch motor can be removed;

[0040] By arranging a plurality of steel cables 500 around the angle steel tower 100 to tighten the angle steel tower 100 from multiple directions, when the angle steel tower 100 tends to tilt, the steel cables 500 in the opposite direction of the tilt of the angle steel tower 100 can exert a reverse pulling force on the angle steel tower 100, thereby preventing the angle steel tower 100 from tilting; when the angle steel tower 100 has already tilted, a plurality of steel cables 500 can be constructed to straighten the angle steel tower 100 from the opposite direction of its tilt, thereby avoiding the harm caused by the tilt of the angle steel tower 100.

[0041] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
