Description

Anti-falling rail fixing fitting for reinforcing iron tower Technical Field The utility model belongs to the technical field of anti-falling rail installation, and particularly relates to an anti-falling rail fixing fitting for reinforcing an iron tower. Background The reinforced iron tower generally comprises four upright posts, the structure of each upright post is shown in fig. 1 and 2, the reinforced iron tower mainly comprises two angle steels, the right angles of the angle steels are oppositely arranged, the two angle steels are fixedly connected through screws by using connecting plates which are arranged in a crisscross manner, and the connecting plates are arranged at a plurality of positions along the height direction of each upright post at intervals. The anti-falling track is a rigid track structure, the cross section is usually T-shaped, the anti-falling track is laid on the outer side of an upright post of an iron tower in parallel, an anti-falling device is arranged on the anti-falling track, an operator is connected with the anti-falling device by a safety rope tied between waists when climbing the iron tower, and the anti-falling device is automatically locked on the anti-falling track when falling outside the waist, so that the safety of the operator is ensured. When single angle steel is as the stand, the right angle limit of angle steel outwards sets up, when installing the anti-falling track on this kind of stand, can directly be with anti-falling track through welded mode connection in the right angle outside of angle steel, because the right angle position of angle steel has higher intensity, consequently can guarantee the orbital installation strength of anti-falling better. However, for the upright post of the reinforced iron tower, the right-angle sides of the two angle steels are positioned in the middle of the upright post, so that the anti-falling rail is inconvenient to connect. Therefore, how to solve the problem of the anti-falling track connection of the reinforced iron tower is a main object of the application. Disclosure of utility model In order to solve the defects in the prior art, the utility model provides the anti-falling rail fixing hardware fitting for the reinforced iron tower, which is convenient for the installation of the anti-falling rail of the reinforced iron tower, and has higher connection strength and installation convenience. In order to achieve the object of the utility model, the following scheme is adopted: A prevent weighing down track fixed fitting for strengthening iron tower, strengthen the stand of iron tower and include two angle steel of parallel arrangement, the right angle of angle steel sets up relatively, and two angle steel link to each other through the connecting plate of cross, and the connecting plate is laminated with the lateral wall of angle steel. The fixing hardware fitting comprises a screw and two clamping plates; the clamping plate comprises an end plate and an outer clamping plate which are mutually perpendicular, and the end plate is provided with a through hole for threading a screw rod; during the equipment, the screw rod wears to locate between two angle steel along the length direction of one of them connecting plate, and the both ends of screw rod are protruding in the outside of two angle steel respectively, and the screw rod is laminated with the curb plate outer wall of angle steel, and the cardboard passes through the through-hole and links to each other with the screw rod, and the screw rod tip is equipped with lock nut for compress tightly the end plate in the border of angle steel curb plate, and outer splint are located the contained angle inboard of corresponding angle steel, and laminate with the angle steel curb plate inner wall that corresponds, prevent weighing down rail connection in the one end of screw rod. The utility model has the beneficial effects that: 1. The scheme utilizes the cooperation of the clamping plate and the screw rod, and utilizes the locking nut to lock, so that the screw rod is fixedly connected to the upright post of the reinforced iron tower, and the anti-falling rail is installed by means of the screw rod, so that the stability of the anti-falling rail installation structure is effectively ensured. 2.
