Description

Technical Field

[0001] The utility model relates to the technical field of boiler steel structure foundation bolt construction, in particular to a boiler steel structure foundation bolt installation and adjustment tool. Background Art

[0002] As the largest and tallest steel structure equipment in a power plant, the boiler also requires very precise installation requirements for the foundation bolts of the equipment, because it is related to the installation quality and safety of the boiler. Since the anchor bolts are pre-buried, when we pour them, there will be a certain impact and shaking on the anchor bolt body. Due to the lack of an effective fixing method, the anchor bolts are found to be offset after pouring, resulting in errors, which brings hidden dangers to the subsequent installation. In some sites, the pre-buried size of the anchor bolts is greatly offset and requires secondary processing. Therefore, in view of the above situation, it is urgent to provide a furnace steel structure anchor bolt installation and adjustment tool to overcome the shortcomings in current practical applications.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-4 In an embodiment of the utility model, a boiler steel structure anchor bolt installation and adjustment tool comprises a frame 1, a reinforcement layer plate 2 is horizontally installed inside the frame 1, a plurality of anchor bolts 3 are penetrated through the upper end surface of the frame 1, and the ends of the plurality of anchor bolts 3 all penetrate the reinforcement layer plate 2, an adjustment mechanism is installed on the surface of the reinforcement layer plate 2, and is configured to adjust the height of the anchor bolts 3, and a leveling mechanism is installed on the frame 1, and is configured to adjust the verticality of the anchor bolts 3.

[0017] Specifically, the frame 1 is a channel steel profile structure, and four legs extend downward from the four corners of the lower end face of the frame 1, and the reinforcement layer 2 is welded between the four legs. Holes adapted to the anchor bolts 3 are provided on the frame 1 and the reinforcement layer 2, so that the ends of the anchor bolts 3 can pass through the holes conveniently, and the anchor bolts 3 are doubly locked by the frame 1 and the reinforcement layer 2 to avoid certain impact and shaking of the anchor bolts 3 during pouring, thereby further improving the stability of the anchor bolts 3. Secondly, the height of the anchor bolts 3 relative to the reinforcement layer 2 is adjusted by the adjustment mechanism, and the verticality of the anchor bolts 3 relative to the ground is adjusted under the action of the leveling mechanism, so that the anchor bolts 3 remain vertical during pouring.
