Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Shown in Fig. 1-4, hand-hydraulic guide rope tightening device comprises aboveground tensioning portion 1 and shaft bottom fixed part 2 two parts, is connected by steel rope 12; The structure of aboveground tensioning portion 1 is: positioning and fixing plate 8 is fixed on the sheave wheel platform support beam 9, there is rectangular opening 18 its middle, main arm-tie 16 passes the center of the longitudinal axis of the rectangular opening 18 of positioning and fixing plate 8 and main arm-tie 16 by the rectangular opening 18 of positioning and fixing plate 8, its lower end is connected with wedge capping 11 with bearing pin 10,16 longitudinal axis places are evenly distributed with pin shaft hole 19 at main arm-tie, wedge capping 11 is connected with steel rope 12, so the axis of steel rope 12 overlaps with the longitudinal axis of main arm-tie 16; On the positioning and fixing plate 8, the both sides of main arm-tie 16 all have the lateral section be doorframe shape " " supporting seat 4 and the back-up block 6 in supporting seat 4 frames, adjust voussoir 7, arc-shaped concave 20 is arranged on back-up block 6, and fixedly the pin shaft hole 19 that passes on the main arm-tie 16 of transverse axis 5 is placed on the back-up block 6; On two supporting seats 4 oil jack 3 is housed all, tensioning transverse axis 17 passes the top that pin shaft hole 19 on the main arm-tie 16 is placed on oil jack 3.Shaft bottom fixed part 2 by wedge shape anchor fitting 14 be fixed on the shaft bottom platform fixedly girder steel 13 below, wedge shape anchor fitting 14 is connected with steel rope 12.
During tensioning, the manual oil jack 3 of manual operation, pin shaft hole spacing on the stroke of oil jack 3 and the main arm-tie 16 is complementary, the piston rod of two jacks 3 is overhanging, promote to move on the tensioning transverse axis 17, by carrying steel rope 12 on tensioning master arm-tie 16 and the wedge capping 11, the longitudinal axis of main arm-tie 16 is by the center of positioning and fixing plate 8, and with the dead in line of steel rope 12, then the center of positioning and fixing plate 8 is the control position of steel rope 12 in the cage guide, because this moment, steel rope 12 bottoms were fixing, so steel rope 12 is tightened up gradually, along with the increase of tightening force, jack 3 oil pressure indicator indexes also increase, when reaching the tensioning pressure that needs, put on fixedly transverse axis 5, and utilize and adjust voussoir 7, back-up block 6 is with fixedly transverse axis 5 is sturdy, and jack 3 oil returns are removed then, and the tensioning process finishes.
When needing the tension force of inspection guide rope 12, manual operation jack 3 makes piston rod overhanging, notes observing the indication of jack 3 oil pressure indicators simultaneously, and when fixedly transverse axis 5 had just left back-up block 6, the force value of reading oil pressure indicator compared this value and specified value.If less than specified value, the steel rope 12 tension force deficiencies of irritating in the road are described, should carry out tensioning and fixing by slack-free method, reach specified value.Equal specified value as reading, illustrate that steel rope 12 tension force in the cage guide meet the demands.If reading illustrates overtension greater than specified value, can take to remove adjust voussoir 7 and on put fixedly way minimizing guide rope 12 tension force of transverse axis 5.
