Background technology
At present, slider of hydraulic press and cylinder connecting device generally adopt integral (type) flange, and flange is connected with cylinder piston rod by screw thread, and flange is connected with slide block by screw assembly.Single-cylinder hydraulic machine due to work time unbalance loading or oil cylinder and the maintaining of slide block attachment screw improper, easily cause the degree of tightness of screw to differ, the situations such as unbalance stress.Easily cause attachment screw to rupture in this case or adpting flange fracture, slide block causes security incident at the falls downward of deadweight.The lighter causes the damage of equipment to affect normally carrying out of production, may cause the injures and deaths of personnel time serious.
Summary of the invention
Technical problem to be solved of the present invention is to provide a kind of slipper block dropping, and can realize timely slider locking when slider of hydraulic press and cylinder piston rod come off, anti-limited slip block falls under gravity.
The present invention solves the problems of the technologies described above by the following technical solutions: a kind of slipper block dropping, comprise check lock lever, drift, supporting seat, supporting pin, unclamp frame, expansion link, connecting rod, support, spring, the bottom of described check lock lever is fixed on the slide block upper surface of hydraulic press, support is fixed on the slide block upper surface of hydraulic press, connecting rod is pivotable to be connected on support, the bottom of one end connection expansion link of connecting rod, the other end is stuck in the Gewindefreistiche of cylinder piston rod, one end of spring be fixed on expansion link a bit, the other end is fixed on connecting rod, spring is in extended state at ordinary times, the bottom of expansion link is pivotable to be connected on connecting rod, the top of expansion link is fixed on the lower end of unclamping frame, described supporting seat upper and lower opening, supporting seat is fixed on the lower surface of top beam of hydraulic machine, accommodation space cross section in the middle of supporting seat is inverted trapezoidal, at least 2 pieces of drifts are placed in inverted trapezoidal accommodation space, the top of drift is also stretched out in the center that described check lock lever surrounds from bottom through at least two pieces of drifts, described upper end of unclamping frame withstands on the lower surface of described drift, described supporting pin is fixed on the lower surface of supporting seat, and supporting pin extends to unclamping frame direction, the end of supporting pin is inserted in and unclamps in the slot of frame.
The invention has the advantages that: realize when slider of hydraulic press and cylinder piston rod come off timely slider locking, anti-limited slip block falls under gravity, and ensure the safety of producing, the present invention is mainly applicable to single-cylinder hydraulic machine, the operating mode that unbalance loading is more serious, apparatus structure is simple, reliability is high.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of slipper block dropping of the present invention, partial cross.
Fig. 2 be in Fig. 1 P to enlarged drawing.
Fig. 3 is supporting pin and position and the structural relation schematic diagram unclamping frame.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Refer to Fig. 1, slipper block dropping of the present invention comprises check lock lever 1, drift 2, supporting seat 3, supporting pin 4, unclamps frame 5, expansion link 6, connecting rod 7, support 8, spring 9.A hydraulic press needs arrange at least two these slipper block droppings of cover, and slipper block dropping needs to arrange in the bilateral symmetry of cylinder piston rod.
Described check lock lever 1, expansion link 6, connecting rod 7, support 8, spring 9 are fixed on the slide block 10 of hydraulic press, move with slide block 10.Described drift 2, supporting seat 3, supporting pin 4, unclamp frame 5, be fixed on top beam of hydraulic machine 20.
Concrete, the bottom of described check lock lever 1 is fixed on slide block 10 upper surface of hydraulic press, support 8 is fixed on slide block 10 upper surface of hydraulic press, connecting rod 7 is pivotable to be connected on support 8, the bottom of one end connection expansion link 6 of connecting rod 7, the other end is stuck in the Gewindefreistiche of cylinder piston rod 22.One end of spring 9 be fixed on expansion link 6 a bit, the other end is fixed on connecting rod 7, is in extended state when spring 9 is flat, and the bottom of expansion link 6 is pivotable to be connected on connecting rod 7, and the top of expansion link 6 is fixed on the lower end of unclamping frame 5.
Described supporting seat 3 upper and lower opening, supporting seat 3 is fixed on the lower surface of top beam of hydraulic machine 20, accommodation space cross section in the middle of supporting seat 3 is inverted trapezoidal, place at least 2 pieces of drifts 2 in inverted trapezoidal accommodation space, the top of drift 2 is also stretched out in the center that described check lock lever 1 surrounds from bottom through at least two pieces of drifts 2.Described upper end of unclamping frame 5 withstands on the lower surface of described drift 2, described supporting pin 4 is fixed on the lower surface of supporting seat 3, and supporting pin 4 extends to unclamping frame 5 direction, the end of supporting pin 4 be inserted in unclamp frame 5 slot in, frame 5 will be unclamped locate, thus under normal condition, unclamping frame 5, to withstand drift 2 motionless.
When attachment screw fracture or adpting flange fracture, slide block 10 is when the falls downward of conducting oneself with dignity, cylinder piston rod 22 and slide block 10 depart from, cylinder piston rod 22 increases with the spacing of slide block 10, under the effect of spring 9, expansion link 6 rotates, drive connecting rod 7, unclamp frame 5 realization rotation, unclamp frame 5 to be separated with supporting pin 4, drift 2, without the support of unclamping frame 5, glides under gravity, realizes the locking to check lock lever 1, because the bottom of check lock lever 1 is fixed on slide block 10 upper surface of hydraulic press, so achieve the locking to slide block 10.Adopt drift 2 to realize stepless locking, go up the function that all effectively can realize slip-off preventing at an arbitrary position.
See Fig. 3, supporting pin 4 adopts 1/4 arc-shaped structure form, when unclamping frame 5 towards arrow direction, because supporting pin 4 adopts 1/4 arc-shaped structure, so it is less to unclamp resistance suffered by frame 5, departing from supporting pin 4 than being easier to, effectively can improve the sensitivity and reliability that come off and detect.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; the any amendment done within all spirit in the invention and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in the invention.
