Embodiment Construction
[0017] As shown in the figure, a cantilever central axis installation device for rotating and opening and closing the roof includes a shaft frame 5, a rotating shaft 6, a base 7, an upper bearing 16, and a lower bearing 17, wherein the base 7 is fixed under the shaft bracket 5, An upper bearing 16 and a lower bearing 17 are respectively arranged in the middle of the shaft frame 5 and the base 7, and the rotating shaft 6 is installed in the rotating shaft device through the upper bearing 16 and the lower bearing 17, and it is characterized in that: the upper end of the rotating shaft 6 protrudes The upper bearing 16, and the top cap 3 is installed at the upper end. The top cap 3 is provided with a mounting seat 2 fixedly connected with the cantilever 1. The mounting seat 2 is sleeved on the top cap 3, and the lower edge of the mounting seat 2 is connected to the top by bolts. The cap 3 is fixedly installed; the top cap 3 is provided with a stepped blind hole with a lower opening...

The invention relates to a cantilever center shaft mounting device for roof rotary opening and closing. The cantilever center shaft mounting device comprises a shaft frame, a rotary shaft, a base, anupper bearing and a lower bearing, the base is fixedly arranged on the lower portion of the shaft frame, and the rotary shaft is mounted in the rotary shaft device through the upper bearing and the lower bearing. The upper end of the rotary shaft extends out of the upper bearing, a step blind hole with an opening in the lower portion is formed in a top cap, and the diameter of the lower portion ofthe blind hole is larger than that of the upper portion of the blind hole. An axial positioning device is arranged below the upper bearing and comprises a fixing ring mounted on the rotary shaft. Wheel axles are evenly arranged on the periphery of the fixing ring, and pressing wheels are mounted at the front ends of the wheel axles. In the rotary shaft device, the top of the rotary shaft is provided with the top cap with the damping effect, a mounting seat connected with a cantilever is fixedly connected with the top cap through bolts, the situation that the mounting seat is directly connected with the rotary shaft is avoided through arrangement, when the cantilever vibrates under the effect of external force, the top cap can effectively buffer vibration, and thus the influence on the rotary shaft is avoided; and through the axial positioning device arranged on the lower portion of the shaft frame, the rotary shaft can be axially positioned, and stable rotation of the rotary shaft isensured.
Description
technical field [0001] The invention relates to a cantilever central axis installation device for rotating and opening and closing a roof, belonging to the field of opening and closing roof devices. Background technique [0002] With the enhancement of my country's comprehensive national strength and the development of sports, domestic stadiums and gymnasiums with open and close roofs are also emerging, and continue to extend to various fields such as hotels, courtyards, and commercial plaza atriums. The design of the retractable roof involves multiple disciplines such as architecture, structure, machinery, and automation control. At present, the corresponding national technical specifications and standards have not been formulated in China. Opening and closing roofs have different opening and closing forms, that is, one or more movable units that make up the movable roof follow a certain track and move in a short period of time, so that the roof can be opened and closed. T...
