Description
Technical field
This utility model belongs to engineering machinery field, specifically, particularly relates to a kind of hydraulic oil cylinder protective device.
Background technology
At present, the hydraulic oil cylinder protective device of engineering machinery is mainly a bending plate or flat board as backplate, and this backplate is fixed on piston rod end, moves along with the motion of piston rod, thus protecting cylinder piston rod not smashed by foreign body.But the backplate of this kind of structure is easily smashed by stone or foreign body, causing that backplate deforms, when oil cylinder carries out stretching out, bounces back, backplate withstands on cylinder cap, causes backplate bending to deform.After piston rod loses the protection of backplate, it is easy to cause hydraulic jack premature failure.
Summary of the invention
The purpose of this utility model is in that to overcome drawbacks described above, it is provided that a kind of hydraulic oil cylinder protective device, its simple in construction, and intensity is good, easy to use, it is possible to effectively extend the service life of hydraulic jack.
Described hydraulic oil cylinder protective device, including the bending plate coordinated with cylinder piston rod, is provided with skeleton bottom described bending plate, skeleton is respectively provided on two sides with riser, steel plate and two risers and coordinates.
Further, described steel plate is connected with plural anchor ear, and anchor ear is provided with silk seat, and Interal fixation is on silk seat.
Further, described anchor ear is semicircle.
Compared with prior art, the beneficial effects of the utility model are:
This utility model simple in construction, intensity is good, makes easy to use, it is possible to be attached to above hydraulic jack easily, is added the intensity of bending plate by skeleton；The steel plate set up on cylinder tube, it is ensured that the safety of cylinder tube, effectively extends the service life of hydraulic jack, it is adaptable to the bad working environments such as mine.
Accompanying drawing explanation
Fig. 1 is use state reference map of the present utility model；
Fig. 2 is the structural representation that steel plate coordinates with cylinder tube；
Fig. 3 is the upward view of bending plate.
In figure, 1, bending plate；2, anchor ear；3, steel plate；4, silk seat；5, cylinder tube；6, riser；7, skeleton.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in figures 1 and 3, hydraulic oil cylinder protective device, including the bending plate 1 coordinated with cylinder piston rod, bottom described bending plate 1, it is provided with skeleton 7, skeleton 7 is respectively provided on two sides with riser 6, and steel plate 3 coordinates with two risers 6.
As in figure 2 it is shown, described steel plate 3 is connected with plural anchor ear 2, anchor ear 2 is provided with silk seat 4, and steel plate 3 is fixed on silk seat 4.
During installation; steel plate 3 is fixed on cylinder tube 5 by anchor ear 2; this utility model is in use; when hydraulic jack is flexible back and forth, bending plate 1 is slid at steel plate 3 by two risers 6, when under having foreign body to pound; external force can be passed to cylinder tube 5 by bending plate 1 and steel plate 3; and the intensity of cylinder tube 5 is sufficiently large, thus protecting bending plate 1, reach the purpose of protection piston rod.
