Embodiment Construction

[0023] Now, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0024] Such as Figure 1 to Figure 4 As shown, the present invention is provided with a box body 1 and a turbine shaft 3, and the box body 1 meets the anti-seismic requirements of nuclear power plants. The box body 1 is provided with an upper cover plate 18, a lower bottom plate 19 and a side cover plate 20. The upper cover plate 18 and the side cover plate 20 are detachable and fastened to the box body 1 by bolts for installation, debugging and observation use. The turbine shaft 3 is provided with two upper and lower bearings 21, which are respectively fixedly connected with the upper cover plate 18 and the lower bottom plate 19 of the casing 1 through bolts. A turbine 2 is also provided on the turbine shaft 3 inside the casing 1 , which is adjacent to a bearing 21 above the turbine shaft 3 .

[0025] The turbine shaft 3 passes through the ca...

Abstract

The invention provides transmission cases on two sides of a personnel airlock. The transmission cases solve the technical problems that transmission cases on two sides of an existing personnel airlock are complex in structure, large in adjustment difficulty coefficient and poor in practicability and time and labors are wasted in operation. Each transmission case is provided with an upper cover plate, a lower bottom plate, side cover plates, a worm, a worm-wheel shaft, a rotating shaft and an interlocking device; the worm-wheel shaft is provided with a bearing and longitudinally penetrates through a box body and is fixedly connected with the box body through the bearing; the worm and the rotating shaft transversely penetrate through the box body and are fixedly connected with the box body, and the worm is meshed with a worm wheel. The transmission cases on the two sides of the personnel airlock can be widely applied to the transmission field.

Description

technical field [0001] The invention relates to a personnel gate, in particular to a transmission box on both sides of the personnel gate. Background technique [0002] In the field of nuclear power plants, personnel gates are installed on the containment of pressurized water reactor nuclear power plants. The personnel gate is the channel for the operation, security inspection and maintenance personnel to enter and exit the containment during the reactor shutdown, refueling and operation. At the same time, it can also be used for the transportation of some small equipment such as tools and instruments. The transmission boxes on both sides of the personnel gate are located on both sides of the personnel gate, and are a key component of the transmission system of the personnel gate. It forms a complete transmission system together with transmission shafts, couplings, middle transmission boxes, gears and other transmission mechanisms, which is the basis for completing the fun...
