Detailed description of the invention
Embodiment 1:
The present embodiment provides a kind of lifting mode maintenance ladder, as shown in Figure 1, comprise the base 1 of cuboid shape, lifter plate 3 and Manual hydraulic jack 4, the corner place of base 1 upper surface is separately installed with track post 2, four track posts 2 are each passed through the corner of lifter plate 3, Manual hydraulic jack 4 is oppositely fixed on lifter plate 3 lower surface, the spanner 5 of Manual hydraulic jack 4 is fixed on the upper surface of lifter plate 3, the end winding support of the expansion link of Manual hydraulic jack 4 is on base 1, the below of base 1 is provided with movable pulley 6, and movable pulley 6 is provided with stop motion mechanism 16.Described movable pulley is rubber wheel.
When operation climbed by needs, by movable pulley 6, this lifting mode maintenance ladder of the present embodiment can be passed job position by operating personnel easily, single unit system is fixed by the stop motion mechanism 16 then arranged by movable pulley 6, then operating personnel stands on lifter plate 3, by spanner 5, Manual hydraulic jack 4 is worked, Manual hydraulic jack 4 can promote lifter plate 3 to carry out rising and declining, do after arriving assigned address, here hydraulic jack principle of work belongs to existing mature technology, does not illustrate.Due to the effect of four track posts 2, lifter plate 3 is made stably to rise and decline and lateral deviation can not occur.
Usually the use of this device needs at least two operating personnels to carry out, an operation.Another one is steadying the ladder below.Base 1 in the present embodiment generally adopts heavier base further, like this, can make below single unit system relatively more firm, also not easily inclination accident occur when one-man service.
Embodiment 2:
On the basis of embodiment 1, describe in conjunction with such as Fig. 1,2,3, because the weight of base 1 is natively heavier, add the weight of operating personnel when operation, what make movable pulley 6 bears weight ratio comparatively greatly, easily causes damage, therefore in the present embodiment, the lower incline position of base 1 is provided with rectangular support block 7 by bearing pin, and rectangular support block 7 can rotate by the lower incline around base 1 under bearing pin effect, and the height of described rectangular support block 7 equals the height of base 1 apart from ground.
Time general, rectangular support block 7 receives to lean against the side of base 1, when enforcement operation, by the effect of bearing pin, rectangular support block 7 is rotated 180 °, such rectangular support block 7 is just in the bottom of base 1, play the effect of support, height due to rectangular support block 7 equals the height of base 1 apart from ground, if so movable pulley 6 to bear weight smaller, when can not deform, rectangular support block 7 is inoperative, when movable pulley 6 to bear weight ratio larger, movable pulley 6 deforms, movable pulley 6 after distortion makes base 1 certainly be less than the height of rectangular support block 7 apart from the height on ground, now rectangular support block 7 can replace movable pulley 6 to play a supporting role, protect the use of movable pulley 6.
Embodiment 3:
When in use, it is very important for can fixing to ladder, and this ladder of the present utility model is with movable pulley, so be fixedly very necessary, the stop motion mechanism 16 of the movable pulley 6 mentioned in embodiment 1 solves fixing problem.
Describe in conjunction with such as Fig. 1,2,3,4, stop motion mechanism 16 can be the fixing brake block structure of tradition, ladder can be made to fix with the effect of brake.
In the present embodiment, as shown in Figures 2 and 3, movable pulley 6, for dispersing spoke wheel, has uniform multiple spokes 8 in movable pulley 6, movable pulley 6 inside is divided into multiple hole 9 by multiple spoke 8.The stop motion mechanism 16 of movable pulley 6 comprises two plectanes 12, two plectanes 12 are separately fixed at the two ends of connecting panel 11, the length of connecting panel 11 equals the distance between former and later two movable pulleys 6, and plectane 12 is provided with multiple stop rod 10, and the distribution of stop rod 10 is corresponding with hole 9.
When needs braking fixed position, in hole 9 between the spoke 8 stop rod 10 on the connecting panel 11 two ends plectane 12 of stop motion mechanism 16 being inserted respectively movable pulley 6, length due to connecting panel 11 equals the distance between former and later two movable pulleys 6, so stop motion mechanism 16 just can be inserted in former and later two wheels, like this because stop rod 10 can not rotate, movable pulley 6 can not be rotated.
Such as, in the present embodiment, spoke 8 has three, and movable pulley 6 inside is divided into three holes 9, then corresponding stop motion mechanism 16 two respectively on have three stop rods 10, three stop rods 10 are inserted respectively the effect just reaching fixed ladder in three holes 9 of movable pulley 6.
Embodiment 4: combine as Fig. 1,2,3,4 describes.
Embodiment 1 further improves by the present embodiment, on the basis of embodiment 1, the present embodiment middle orbit post 2 is threaded connection by the pole that more piece is smooth and forms, as shown in Fig. 1,4, lifter plate 3 is had the ball seat 14 being installed with ball by the through hole internal fixtion that track post 2 passes, track post 2 is provided with vertical rail groove 15, the ball on ball seat 14 falls within rail groove 15.
This structure makes track post 2 can split into a few joint at ordinary times, only just builds when in use temporarily, facilitates depositing of equipment.And, can select to build concrete height according to the concrete height of operation.Now a joint track post 2 is bottom fixed when operation, then along with the rising of lifter plate 3, connect other track post 2 successively until arrive operation height position, in the process risen, ball in ball seat 14 roll in rail groove 15 and with track post surface scrolls, friction force is reduced, rises more laborsaving.
In the present embodiment, have ingathering chamber 13 in base 1 side, when not operation at ordinary times, track post 2 can split into multiple trifle, deposits in ingathering chamber 13, and stop motion mechanism 16 also can exist in ingathering chamber 13.
The utility model is that the technical scheme of detailed description or the structure of technical characteristic all adopt prior art or architectural feature in addition.
More than exemplifying is only to casehistory of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
