Abstract
The utility model discloses a hydraulic pressure support leg with a mechanical locking mechanism; an arc groove tightly matched with a ball head of a ball head screw is formed by oppositely combining grooves at inner sides of two cover boards, the lower end of a hydraulic cylinder body is fixed with the upper end of a shell through a flange, lifting lugs are fixed at the lower end of the shell, the ball head screw is arranged in the shell, the upper end of the ball head screw is disassembly fixed with the lower end of a piston rod, the lower end of the ball head screw is arranged in a ball socket groove of a fixing seat and is locked and fixed by two cover boards; and when the piston rod is in a contraction position, an opposite-open locking block of which the upper end is provided with a connecting plate is fixed at the contact position of the ball head screw and the shell. When the hydraulic pressure support leg works, the connecting plate on the opposite-open locking block is fixed with the lifting lugs at the lower end of the shell to realize mechanical locking, so as to reduce the effect of load to a hydraulic cylinder and a hydraulic pressure oil path, reduce probability that the hydraulic cylinder leaks oil outwards, enable the hydraulic pressure support leg to work stably, and reduce the auto-contraction phenomenon of the piston rod. The hydraulic pressure support leg is particularly suitable for engineering mechanized equipment which uses the mechanized equipment for a long time with high load.
Description
Technical field
The utility model relates to a kind of hydraulic ram that is applicable to construction machinery and equipment equipment long-time, the use hydraulic ram of load greatly.
Background technology
Because some construction machinery and equipment equipments need for a long time, heavy load is used hydraulic ram; Even existing hydraulic ram has been installed bidirectional hydraulic lock; Also, hydraulic oil pipe system cause the phenomenon of the outside leakage of oil of hydraulic actuating cylinder often to take place because surpassing problems such as rated load work or piston packing ring damage for a long time; Make that hydraulic ram can not stable operation, shrinkage phenomenon voluntarily appears in piston rod, and the normal operation of whole vehicle or device is affected.
The utility model content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art, and the hydraulic ram of a kind of working stability, safe and reliable band machinery locking mounting mechanism is provided.
Be to accomplish above-mentioned purpose, the technical solution of the utility model is: a kind of hydraulic ram with the mechanical lock locking mechanism, and it comprises shell, ball screw, splits latch segment, two cover plates, permanent seat, connecting panel and hydraulic actuating cylinder; The two cover plates inboard has the close-fitting arc groove of bulb that merges back formation and ball screw; Hydraulic cylinder body lower end and shell upper end are fixed together through flange, and the shell lower end is fixed with hanger; Ball screw places in the shell, and its upper end removably is fixed together with piston-rod lower end, and the lower end places in the ball-and-socket groove of permanent seat, and is locked by two cover plates; The contact position of ball screw and shell was fixed with the latch segment of splitting that there is connecting panel the upper end when piston rod was in punctured position; During work, connecting panel and the hanger on the shell split on the latch segment are fixed together.
On the above-mentioned said hydraulic actuating cylinder bidirectional hydraulic lock is installed.
Because the hydraulic ram of the utility model is fixed with the latch segment of splitting that there is connecting panel the upper end on ball screw; After piston rod shrinks; The connecting panel of splitting on the latch segment just can be fixed together with the hanger of shell lower end, realizes mechanical interlocking, alleviates the effect of load to hydraulic actuating cylinder and hydraulic circuit; Reduced the chance of occurrence of the outside oil leakage phenomenon of hydraulic actuating cylinder; Make to have stoped piston rod the generation of shrinkage phenomenon voluntarily to occur by the hydraulic ram working stability, therefore reduced the hidden danger that therefore vehicle takes place.Its adjustable height, safe and reliable, easy to use.Be applicable to the construction machinery and equipment equipment of the use hydraulic ram of long-time, big load.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to describe:
Fig. 1 is the inner structure scheme drawing of the utility model.
The specific embodiment
As shown in Figure 1, present embodiment comprises shell 1, ball screw 2, splits latch segment 3, two cover plates 4, permanent seat 5, connecting panel 6 and hydraulic actuating cylinder.Two cover plates 4 inboards have the close-fitting arc groove of bulb that merges back formation and ball screw 2.Hydraulic cylinder body 7 lower ends and shell 1 upper end are fixed together by bolt 9 through the flange 8 of band seam, and shell 1 lower end is welded with hanger 10, perhaps use riveted joint to wait other fixed form.Ball screw 2 places in the shell 1, and there is negative thread its upper end, and there is the outside thread that is complementary with it piston rod 11 lower ends, and the two screw thread is fixed together, and by nut 12 lockings.Ball screw 2 lower ends place in the ball-and-socket groove of permanent seat 5, and two cover plates 4 places on the bulb of ball screw 2, and are fixed together by screw 13.Ball screw 2 was split latch segment 3 with the contact position of shell by screw retention when piston rod 11 was in punctured position, and this screw will split latch segment 3 and the connecting panel 6 on it is fixed together.Have the connecting bore that links together on connecting panel 6 and the hanger 10.During work, the connecting panel of splitting on the latch segment 36 is fixed together with hanger 10 on the shell 1.On the described hydraulic actuating cylinder bidirectional hydraulic lock 14 can be installed.
Claims (2)
1. hydraulic ram with the mechanical lock locking mechanism is characterized in that: it comprises shell, ball screw, splits latch segment, two cover plates, permanent seat, connecting panel and hydraulic actuating cylinder; The two cover plates inboard has the close-fitting arc groove of bulb that merges back formation and ball screw; Hydraulic cylinder body lower end and shell upper end are fixed together through flange, and the shell lower end is fixed with hanger; Ball screw places in the shell, and its upper end removably is fixed together with piston-rod lower end, and the lower end places in the ball-and-socket groove of permanent seat, and is locked by two cover plates; The contact position of ball screw and shell was fixed with the latch segment of splitting that there is connecting panel the upper end when piston rod was in punctured position; During work, connecting panel and the hanger on the shell split on the latch segment are fixed together.
2. the hydraulic ram of band mechanical lock locking mechanism according to claim 1 is characterized in that: on the described hydraulic actuating cylinder bidirectional hydraulic lock is installed.
