The invention provides a thread milling device for a screw. The thread milling device for the screw comprises a machine body, and further comprises a linear drive device, a rotary drive device, a sleeve, a thread milling device and a fixing device which are arranged on the machine body, wherein the fixing device is used for fixing the target screw, the thread milling device is used for cleaning the target screw, the thread milling device is arranged on the inner side of the sleeve, the linear drive device is used for driving one of the fixing device and the sleeve to move in the axial direction so as to enable the fixing device and the thread milling device to perform relative motion, and the rotary drive device is used for the driving at least one of the fixing device and the sleeve to rotate so as to enable the fixing device and the thread milling device to perform relative rotation. The thread milling device for the screw can automatically complete cleaning for the target screw, meanwhile can further collect iron chippings which fall off from the thread milling device in cleaning through the sleeve, and prevents the iron chippings from falling to the ground. Accordingly, the thread milling device for the screw reduces involved manpower, saves time of workers, and reduces time cost.

The invention provides a suspending device for a bridge detection working vehicle. The suspending device for the bridge detection working vehicle mainly comprises a rear axle steel plate spring suspension device, two or four supporting leveling base, an oil suspension device and a stander assembly; the rear axle steel plate spring suspension device consists of two groups of steel plate springs; each group of steel plate springs is formed by mutually overlapping and fixing a plurality of steel plates with different lengths; each supporting leveling base has a framework structure formed by welding a plurality of steel plates; the oil suspension device comprises a suspension oil cylinder, a supporting foot base, a U-shaped base, a connecting plate, a bidirectional hydraulic lock and a three-position four-way reversing valve; and the stander assembly comprises a chassis vehicle frame and an auxiliary vehicle frame. The steel plate spring suspension and the oil suspension are combined organically, so the suspending device for the bridge detection working vehicle plays a role in buffering and damping during running of the bridge detection working vehicle, and rigidly supporting during working of the bridge detection working vehicle; therefore, the contradiction of buffering and damping during running of the bridge detection working vehicle and rigidly supporting during working of the bridge detection working vehicle can be solved effectively. The suspending device for the bridge detection working vehicle has the characteristics of large bearing capacity, rational fixing position, high stability, low contact stress and high reliability.

The invention discloses a crane hoisting mechanism with an anti-falling type hand-operating device for a nuclear power station. The crane hoisting mechanism comprises an electric motor, a winding drum set, a brake, a brake wheel shaft coupler, a speed reducer and a handle mechanism, wherein a friction sheet I, a friction plate, a fixed plate, a friction plate and a friction sheet II of the handle mechanism are sequentially arranged on the shaft sleeve in a penetrating and sleeving mode; the shaft sleeve is arranged at the front section of a flange shaft sleeve of a flange in the sleeving mode; a central screw hole of the hand wheel is screwed in right-hand threads at the middle section of the flange shaft sleeve; a retainer ring is arranged at the rear section of the flange shaft sleeve of the flange in the penetrating mode; all parts are fixed together by virtue of a disc spring and a nut; springs is arranged between the external circumference of the fixed plate and a fixed flange; and the other end of the fixed flange is fixed on a fixed base through a pin roll. The crane hoisting mechanism has the beneficial effects that the load is prevented from automatically dropping, the structure is simple, the arrangement is convenient, the dismounting is convenient, and the same set of device can be used for multiple hoisting mechanisms.

The invention relates to an engine demounting and mounting trailer. According to the technical scheme, the trailer is composed of a mounting vehicle, a demounting and mounting platform and a hydraulic system. The mounting vehicle comprises a walking mechanism, two lifting mechanisms, a transverse moving mechanism and a guide rail mechanism. The two lifting mechanisms are installed at the two ends of the walking mechanism respectively and drive the transverse moving mechanism to ascend or descend, and the transverse moving mechanism drives the guide rail mechanism to move. The mounting vehicle and the demounting and mounting platform are movably connected through the guide rail mechanism. The demounting and mounting platform comprises a platform, a longitudinal sliding guide rail, a carriage, a bracket, a main fixing supporting piece, an auxiliary fixing supporting piece, a bearing outrigger, an adjusting pull rod and a traction device.
