Fig. 1 is the structural representation of the utility model terrace finisher specific embodiment;
Fig. 2 be among Fig. 1 K to concrete sectional view;
Fig. 3 is the A-A sectional view among Fig. 1.
The specific embodiment
The specific embodiment of terrace finisher of the present utility model as shown in Figure 1 to Figure 3, be installed with actuating unit 1 on its frame 3, be installed with handrail 14 on the actuating unit 1, be provided with vertical output shaft 2 towards downward-extension in the bottom of actuating unit 1, be fixed with base 9 in the bottom of this output shaft 2, evenly be laid with radially four smear rotating shafts 10 on the base 9, each smear rotating shaft 10 all is rotatably assorted with base 9, equal correspondence is fixed with smear 11 in the bottom of each smear rotating shaft 10, and each smear rotating shaft 10 all is connected with for the angle-adjusting mechanism of adjusting synchronously each smear angle of inclination.This angle-adjusting mechanism comprises along the angle adjustment connecting lever 12 that is fixed on perpendicular to corresponding smear rotating shaft 10 axial directions in each smear rotating shaft 10, slip cap is contained in the axle sleeve 4 on the actuating unit output shaft 2, be fixedly set in the hoisting frame 7 that is in transmission connection with angle adjustment connecting lever 12 on the axle sleeve 4 lower, outer perimeter faces and be installed on driving mechanism (not looking out among the figure) on the handrail 14, axle sleeve 4 radial convex on the outer peripheral face of the upper end of actuating unit 1 is provided with ring platform 40, below ring platform 40, be located at leverage 5, one end of this leverage 5 is hinged on the frame 3, the driving mechanism that arranges on the other end of leverage 5 and the handrail 14 is in transmission connection, and is rotatably equipped with at leverage 5 middle parts and the bearing 6 that encircles platform 40 lower surfaces and roll and cooperate.In the present embodiment, each angle adjustment connecting lever 12 is fixedly set in the corresponding smear rotating shaft 10, and the bearing of trend of each angle adjustment connecting lever 12 is towards the direction of rotation of smear 11; Hoisting frame 7 is fixedly set in axle sleeve 4 on the outer peripheral face of the lower end of base 9, is provided with the L shaped lift arm 8 that cooperates with the 12 corresponding holdings of each angle adjustment connecting lever at hoisting frame 7; Leverage 5 is comprised of two levers that relative spacing is clamped in axle sleeve 4 relative both sides, one end of this two lever is hinged by bearing pin 15 and frame 3, the other end bridge joint of two levers has tie-beam, relatively rotate at the middle part of two levers and to be equipped with bearing 6, driving mechanism comprises that rotating the adjustment handwheel that is assemblied on the handrail 14 reaches the screw nut driven mechanism that is connected with the adjustment handwheel, is connected with draught line 13 between the nut in tie-beam and screw nut driven mechanism.
