[0002] The angle iron is a long strip steel material with two sides perpendicular to each other to form an angle, which can be combined into various force members according to different needs of structures, and can also be used as connecting pieces between members. It is widely used in various building structures and engineering structures, such as power transmission towers, most of which are made of angle iron. Even some power transmission towers that are not made of angle iron, some cross arms on them are also made of angle iron.

[0003] Many devices need to be installed on the power transmission tower for detection, maintenance and the like, including cameras, inertial devices, warning lights, bird repellents and the like.

[0004] The installation of these devices is easy to think of as manually punching holes on the angle iron and then fixing them with fasteners. However, the punching on the angle iron will directly affect the strength of the angle iron, and then the stability and service life of the tower will be affected, and it is best not to punch holes on the angle iron for installation. Therefore, a clamping device currently used without punching holes on the angle iron is shown, two clamping plates similar to the angle iron are used to clamp the angle iron, and then a plurality of bolts and nuts are used to fix the two clamping plates. Since the two clamping plates are separated, in order to balance the force when the clamping plates are fixed, at least four bolts are needed between the two clamping plates to realize stable clamping, which not only increases the installation difficulty of the entire clamping device, but also prolongs the installation time of each clamping device and is low in efficiency.

[0040] The two sides of the sliding groove 4 on the horizontal plate 2 are provided with vertical baffle plates 5, the vertical baffle plates 5 are provided with horizontal guide sliding holes 6, the two sides of the hinge lug 14 of the first plate hook 13 are respectively provided with two guide pins 17, the guide pins 17 are penetrated in the guide sliding holes 6, so that the first plate hook 13 does not fall off the sliding groove 4 when sliding left and right. In some embodiments, one of the guide pins can be used as a penetrating pin to connect the connecting rod 16 and the hinge lug 14 together.

[0041] The two vertical baffle plates 5 of the horizontal plate 2 are connected together through a cover plate 7, so as to strengthen the strength of the vertical baffle plates 5, and the cover plate 7 protects the hinge lug 14 of the first plate hook 13 and the guide pins 17 on the hinge lug 14.

[0042] The two sides of the horizontal plate 2 are provided with lifting lugs 8, the lifting lugs 8 are L-shaped, the lifting lugs 8 are provided with bolt holes 9, and bolts can be screwed into the bolt holes 9, which are used for hooking lifting hooks or binding lifting ropes, etc., so as to lift the quick angle iron clamping device of the utility model to the iron tower.
