Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Like Fig. 2, Fig. 3, Fig. 4, shown in Figure 6; Comprise frame 8, base 6, support oil cylinder 1, the first supporting leg fender bracket, the second supporting leg fender bracket; Support oil cylinder 1 outside is set with the second supporting leg fender bracket, and the second supporting leg fender bracket comprises inner core 3, following shrouding 15, bulb 5, and inner core 3 lower ends are welded with down shrouding 15; Inner core 3 is a square tube type; Following shrouding 15 centers are welded with bulb 5, and the said second supporting leg fender bracket 3 bottoms are fixedly connected with support oil cylinder 1 through laterally inserted locating stud 13, and said locating stud 13 end axis are to being fixed with back-up ring 14.The second supporting leg fender bracket outside is set with the first supporting leg fender bracket, and the first supporting leg fender bracket comprises upper sealing plate 4, outer tube 2, and outer tube 2 welded top have upper sealing plate 4, and outer tube 2 is a square tube type.Respectively be welded with cover 17 about outer tube 2 tops, overlap 17 tops and be provided with muscle, this muscle is welded on the outer tube wall, has supporting effect to overlapping 17.The first supporting leg fender bracket top is connected with support oil cylinder 1 through laterally inserted bearing pin 11, and cover 17 and bearing pin are used to set upright and play the guiding role.Bearing pin 11 two end part axially respectively are fixed with a back-up ring 12.The first supporting leg fender bracket, the second supporting leg fender bracket and support oil cylinder 1 fixed installation are one.Outer tube 2 middle and lower parts are welded with fixed-wing 10, and fixed-wing is provided with crosswise fixed plate 16 and waling, and fixed plate 16 is provided with 8 bolts hole (Fig. 5).Said frame 8 is provided with the frame hole, and the frame hole is identical with number of bolt hole and the position is corresponding.The fixed-wing of the first supporting leg fender bracket is screwed and frame 8 Joints through bolt 9, is serially connected with packing ring on the bolt 9.Said second supporting leg fender bracket lower end bulb 5 fixed card are connected to base 6; Be fixedly connected through bolt and base cover 7 on the base 6, be serially connected with packing ring on the bolt, the convex of base cover 7 for standing upside down; Base cover 7 centers have the hole, and base 6 tops are provided with the groove that is complementary with base cover 7.
As shown in Figure 1, when the rodless cavity oil-feed of support oil cylinder inside, piston rod is just down propped; The second supporting leg fender bracket is down propped together, can protect support oil cylinder, makes it not receive lateral force; Make mud, dust be unlikely to corrode inner seal,, reduce wear to reach protection piston rod and Sealing thereof; Improve working life, the final protection that realizes support oil cylinder.The stroke of down propping is 600 mm, whole supporting leg part can be flexibly between (0-600) mm the arbitrary position pause and prop frame.
When the import of support oil cylinder rod chamber, whole supporting leg part is with regard to retracted upward, and the bulb of support oil cylinder part is just blocked by two locating studs on the second supporting leg fender bracket, and the support oil cylinder fender bracket just follows piston rod to withdraw together like this.
The above is merely the mode of execution of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
