Detailed description of the invention
below in conjunction with drawings and Examples in detail the utility model is described in detail:
a kind of manual train brake device, see in accompanying drawing 1 to accompanying drawing 5, figure:
crank handwheel 1, casing 2, case lid assembly 3, imput shaft bearing 4, the setting lid 5 of active bearings, imput shaft 6, driven bevel pinion 7, driven shaft capping 8, lead screw shaft 9, front shroud 10, back shroud 11, bearing mounting base 12, driving bevel gear 13, left arc plate 14, right arc plate 15, main support 16, connecting rod 17, flat pore structure 1701, feed screw nut 18, screw rod 19, guide groove 20.
the T-shaped structure of feed screw nut 18 of the present embodiment; Imput shaft 6 and driving bevel gear 13 are by two stock key sliding block joint, rotate after crank handwheel 1 can being pulled out certain distance together with imput shaft 6 during use, transfer the motion to T-shaped feed screw nut 18 by driving bevel gear 13 and driven bevel pinion 7 engagement, make T-shaped feed screw nut 18 up-and-down movement.
main support 16 and casing 2 are by high strength exploitation, and main support has bearing mounting base 12, and manufacture craft is simple; Main support 16 is provided with guide groove 20, the external part of T-shaped feed screw nut 18 is placed in guide groove 20 and slides up and down simultaneously, and reach guiding and spacing effect, feed screw nut 18 is connected with lead screw shaft 9, and the bottom of lead screw shaft 9 is placed on bearing mounting base 12.
left arc plate 14 and right arc plate 15 are equipped with in guide groove 20 outside of main support 16, and the forward and backward two sides of main support 16 is front shroud 10 and back shroud 11 respectively.
the upper surface of casing 2 is tilting structure, there is angle in the center of gyration line of case lid assembly 3 and the upper surface of casing 2, there is good dustproof and rainproof feature, case lid assembly 3 and casing 2 are assembled into quick fixation structure, by the screw rod 19 direction fast demountable on rotating box 2, structure is simple, and reliability is strong.
type feed screw nut 18 is directly connected by axis hole with connecting rod 17, and for preventing connecting rod swing from causing sponson and car wall friction, the upper end of connecting rod 17 is provided with the flat pore structure 1701 be connected with feed screw nut 18, prevents connecting rod 17 from swinging with stationary links 17.
connect main support 16 below casing 2, casing 2 and main support 16 connect and compose enclosed construction.
the driving efficiency of this device is high, generation brake holding load is large, reliability is strong, and through pull test and self-locking property test, driving bevel gear 13, driven bevel pinion 7 number of teeth of this device are respectively 20 teeth, 40 teeth, test pulling force when lead screw shaft 9 is Tr36 × 5 is 8000kg, keep 60 minutes, pulling force remains unchanged substantially, and each position is without being obviously out of shape and abnormal noise, flexible operation is reliable, can carry out dismounting repair and maintenance fast.
