Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1,2,3,4,5, the hand winch of a kind of monitoring detector handling of reloading for Nuclear power plants provided by the utility model, this hand winch comprises base assembly, central shaft 3, reel 4, guide deflection sheave 5, click assembly, rotates handle 8. Base assembly comprises base plate 1 and two blocks of wallboards 2 being vertically welded on base plate 1. Wherein one block of wallboard 2 is isosceles trapezoid; Another block wallboard 2 extends forward, the axle of guide deflection sheave 5 is inserted in this wallboard 2 front end and guide deflection sheave 5 can rotate in wallboard 2, being provided with gasket ring 11 between guide deflection sheave 5 and wallboard 2, gasket ring 11 is enclosed within outside the axle of guide deflection sheave 5, so that guide deflection sheave 5 can better coordinate with reel 4. Base plate 1 is arranged symmetrically with two bolts hole, by two bolts hole, two bolts 14, this hand winch has been fixed on vertical shaft limit 15.
Central shaft 3 passes the centre hole of reel 4, and the two ends of central shaft 3 are inserted in two blocks of wallboards 2 respectively, are engaged by boss groove between central shaft 3 with reel 4, and reel 4 can rotate under central shaft 3 drives in wallboard 2. Reel 4 both sides are respectively provided with a baffle plate, and reel 4 is drilled with a screw, and wireline 12 relies on this screw and is bolted on reel 4, and the baffle plate of reel 4 both sides can stop wireline 12 landing. Click assembly comprises ratchet 6 and ratchet 7; The centre hole of ratchet 6 is enclosed within outside one end of central shaft 3, and ratchet is positioned at outside the adjacent wallboard of this central shaft 32, it is fixedly connected with end cap 10 by pad 9 between central shaft 3 with ratchet 6, ratchet 7 is rotatably installed on wallboard 2 by bearing pin, the profile of tooth of ratchet 6 and the profile of tooth of ratchet 7 engage each other, it is possible to play braking effect. The centre hole rotating handle 8 be enclosed within the other end of central shaft 3 outer, be fixedly connected with by screw between the two, and rotate handle 8 and be positioned at outside the wallboard 2 adjacent with this central shaft 3, can band movable reel 4 and ratchet 6 rotate by rotating handle 8.
