Description

Safety protection device for fan foundation anchor bolt cage construction Technical Field The utility model relates to a safety protection device for fan construction, in particular to a safety protection device for fan foundation anchor bolt cage construction. Background The fan foundation anchor bolt cage is a key component in the foundation structure of the wind driven generator, and the height of the fan foundation anchor bolt cage is larger than 4 meters, and the fan foundation anchor bolt cage mainly comprises a lower anchor plate 8, an anchor bolt 7, an upper anchor plate 1 and a lower anchor support 9 at the bottom (shown in figure 1). The upper anchor plate 1 and the anchor bolts 7 are adjusted, checked and accepted above the fan foundation, and the fan foundation reinforcement bars are bound and the like, so that the upper anchor plate 1 is required to be constructed, and the fan foundation reinforcement bars belong to high-altitude operation. In the construction process, the lifting hook of the multipurpose automobile crane lifts the safety belt to serve as personnel safety protection, but the shaking of the lifting hook can cause instability of constructors and fall of the anchor bolt cage, and when the automobile crane is not on site, the safety protection device is not available in construction on the upper anchor plate 1, so that personnel fall easily occurs in the construction process. The problem that a safety protection device is not available for installation and acceptance of an anchor bolt and an anchor plate on the basis of a fan exists. Meanwhile, in the construction process, if the automobile crane is adopted for safety protection of constructors, the construction cost is higher, for example, 2000 yuan is needed for a station class by using 25 tons of automobile cranes. Four shifts are needed for adjusting, checking and accepting the anchor bolts 7 and binding the reinforcing steel bars, 8000 yuan of mechanical cost is needed, and the anchor bolts can be used for hanging construction of personnel safety belts, so that the use efficiency is low. Disclosure of Invention Aiming at the technical problems, the utility model provides a safety protection device, which ensures the construction safety of personnel during installation, inspection and acceptance of a fan foundation anchor bolt cage, improves the working efficiency of installation and acceptance, improves the protection effect of construction and reduces the construction cost. In order to achieve the above purpose, the present utility model adopts the following technical scheme. A safety protection device for construction of a fan foundation anchor bolt cage comprises a circular upper anchor plate provided with an anchor bolt, wherein clamping devices in a Z shape are clamped on the inner side and the outer side of the upper anchor plate respectively, the lower ends of the clamping devices are fixedly connected with a strip-shaped bottom plate on the bottom surface of the upper anchor plate through bolts, the upper ends of the clamping devices are pressed on the inner side and the outer side of the upper anchor plate through bolts, supporting rods are vertically arranged on the inner ends of the bottom plate, through holes are formed in the top ends of the supporting rods, safety ropes are connected in the through holes of the adjacent supporting rods in series, bolts are arranged at the middle sections of the supporting rods, one ends of the inclined supporting rods are connected with the bolts, and the other ends of the inclined supporting rods are connected with the lower ends of the clamping devices. Further, the diagonal brace is a steel tube, round steel or steel cable. Further, the supporting rod is a square steel pipe or a round pipe. Further, the heights of the through holes at the top ends of the support rods are consistent. Further, at least six long strip bottom plates are uniformly distributed below the upper anchor plate. Further, the safety ropes are sequentially connected with the through holes of the adjacent support rods in series. The utility model adopts the fixture and is connected through the square pipe bracket and the safety rope in a combined way, and the check personnel directly hang the hook on the safety belt on the safety rope in the fan installation and check processes to form a safety protection device, thereby playing a role in safety protection for personnel constructors, avoiding the occurrence of high-altitude falling accidents, being convenient for disassembly and installation, being convenient for shipment due to the bolt connection, being capable of being used repeatedly and greatly reducing the construction cost. The safety protection device can be used for steel roof truss, purline and roof boarding during the construction of steel structure factory buildings.
