The invention discloses an error processing method of the output signal of an optical-fiber scopperil component and belongs to the error processing methods of the output signal of an optical-fiber scopperil component in an inertial navigation system. The concrete steps of the processing method are that: an output signal model of the optical-fiber scopperil component and an error model thereof arebuilt; the marking and the compensation of the fixed error of the optical-fiber scopperil component are implemented; the self-adaptive filtering of the random error of the optical-fiber scopperil component is implemented. The processing method effectively reduces the zero-offset drift of the optical-fiber scopperil component which is caused by temperature changes, has high marking precision of the fixed error, high marking efficiency and good adaptability; furthermore, the processing method effectively reduces the random error of optical-fiber scopperil, has small amount of computation, and is suitable for real industrial applications.

The solution of the present application can solve the problem that the casing and the appearance part are difficult to assemble.

A balancing device used for a transition draw gear is arranged on the upper end face of the transition draw gear. The balancing device comprises rotating shafts, a rotating rod and a top base, wherein the rotating shafts, the rotating rod and the top base are arranged on the transition draw gear. The rotating rod comprises an upper end plate and a lower end plate, wherein a sloping embossment is arranged between the upper end plate and the lower end plate, the sloping embossment is located on a side face of the lower end plate and of a one-piece protruding structure, by taking the upper end plate and the lower end plate of the rotating rod as the reference, the sloping embossment is of a structure of inclining out of the rotating rod in the longitudinal direction, one end of the rotating rod is arranged on one of the rotating shafts, the other end of the rotating rod is provided with a hinge pin, a swing bolt is further arranged on the hinge pin, and the rotating rod can rotate around the one of the rotating shafts and hinged to the swing bolt through the hinge pin. A through hole is formed in the top base, the swing bolt penetrates through the through hole of the top base, the tail end of the swing bolt is fixedly provided with a nut, a spring is arranged between the nut and the through hole of the top base, and the diameter of the spring is larger than the diameter of the through hole of the top base. According to the balancing device, the phenomenon that the head of transition draw gear falls when the draw gear is coupled up can be effectively avoided, and the transition draw gear is kept horizontal after being installed.

The invention relates to a frame of a multifunctional special car, belonging to the field of the car. The frame of the multifunctional special car is provided with a front upper frame and is characterized in that the front upper frame and lower frame front small vertical beams are connected through a front small frame; the left and right lower frame front small vertical beams are welded with left and right lower frame vertical beams, and left and right front vertical columns through front first circular tube type cross beams; the upper ends of the left and right front vertical columns are welded at the two ends of the front upper frame and upper cross beams of the front vertical columns are connected with the left and right front vertical columns; the upper cross beams of the front vertical columns are connected with the lower frame front small vertical beams through a connecting frame; lower frame second circular tube type cross beams are welded with the left and right lower frame front small vertical beams and the left and right lower frame vertical beams; the left and right lower frame vertical beams are welded together through front and back third circular tube type cross beams; the lower frame vertical beams are connected with the front ends of upper frame vertical beams through upper and lower frame connecting angle steel; an upper frame rear cross beam is welded between the back ends of the two upper frame vertical beams; and the two ends of lower frame rear circular tube cross beams pass through the left and right lower frame vertical frames and are welded with left and right rear plate spring front lifting lugs.

The invention discloses a core flow distribution device for a lower chamber of a stack internal component, comprising a bottom plate on which a circular ring plate and an adjustment ring are alternately stacked, and a bolt column passes through the circular ring plate and the adjustment ring and connects to the bottom plate. The bottom plate is fixed under the lower plate of the core, and a water flow hole is arranged on the bottom plate. In the present invention, a plurality of water flow holes are arranged on the bottom plate, and the space between the cylindrical structure and the reactor shell is used as a passage for the coolant. With a small amount of offset, after the upward movement along the axial length of the cylindrical structure, its lateral flow is gradually eliminated under the leadership of the axial movement, and when it finally reaches the lower plate of the core, the purpose of complete upward movement is achieved. Compared with the multi-directional flow mixing and then upward process in the prior art, the eddy current is greatly reduced or even eliminated, the flow stability of the coolant is greatly improved, and foreign objects above a certain size are prevented from damaging the main equipment.
