Assembled steel beam bolt tightening device

Abstract

The invention relates to the technical field of bolt tightening devices, in particular to an assembled steel beam bolt tightening device. The bolt tightening device comprises a tightening head, a topsleeve section, plug pins, standard sections and a tightening section; the tightening head is connected to the upper end of the top sleeve section and composed of a sleeve, a spring and a magnetic block; and the spring is fixed to the bottom end of the interior of the sleeve in an embedded connection mode. By arranging a bolt on the magnetic block of the tightening head, the bolt tightening quality, efficiency and safety can be improved, and by increasing and decreasing the quantity of the standard sections, the length of the bolt tightening device can be freely changed so that the bolt tightening device can be suitable for tightening construction of bolts different in height; the tightening section can be rotated freely, thus, bolt tightening construction is facilitated, the working efficiency is improved, there is no need to set up a lot of scaffolds, manpower and material resources are greatly saved, no large-size mechanical equipment is needed to cooperate with the bolt tighteningdevice for construction, and the bolt tightening device is not limited by the situation of the ground below; and the problems that according to an existing steel beam bolt tightening device, scaffoldsneed to be set up, and a construction lift truck needs to be used are solved.

Description

technical field [0001] The invention relates to the technical field of bolt tightening devices, in particular to an assembled steel beam bolt tightening device. Background technique [0002] At present, most industrial workshops use steel structures as the main building, and cranes are often installed in the workshops for hoisting heavy objects. The vibration of the cranes during the years of operation causes the factory building bolts to loosen. As time goes by, the steel beams The connecting bolts between the beams began to loosen under the influence of the vibration of the running beam, and some even fell off, which brought serious safety hazards to the use of the factory building. Therefore, the owner needs to regularly check the high-strength bolts of the steel beams. Tighten in time to ensure the safety and stability of the main structure. [0003] With the existing bolt tightening device, the progress of setting up the scaffolding operation platform on site is relati...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides an assembled steel beam bolt tightening device, which not only does not need to set up a temporary construction operation platform for scaffolding, but also provides convenience for the tightening construction of steel beam bolts, and can be used when the construction site is limited. The advantages of construction and other advantages solve the problems of the existing steel beam bolt tightening device, the need to set up scaffolding and use construction lift trucks
