Further, an end of described pull bar is T connector, is fixedly installed a fixture block on the described thing that is locked, and is provided with draw-in groove on the described fixture block, and described T connector and described draw-in groove match, and also connects the handle that the described pull bar of a rotation is set on the described pull bar.
Further, described draw-in groove comprises a continuous little slotted eye and a large slotted eye, and the width of described little slotted eye is slightly larger than the external diameter of described pull bar, and the width of described large slotted eye is slightly larger than the length of the described T connector of described pull bar.
Further, have square outer rim on the position of the corresponding described handle of described pull bar, described taper knob is contained in the described pull bar outside.
Further, holder is installed also on the described fixture, the support section turning set of described handle is contained in the described holder.
Further, described spring is the dish spring.
Further, described fixture is the walking beam of straightener, and the described thing that is locked is the top roll box.
Beneficial effect of the present invention is, the present invention compared with prior art, use the pull bar clamping thing that is locked among the present invention, pull bar relies on the piston that links to each other to drive by the pressure oil liquid that drives oil pocket, and the restoring force by spring will be locked the thing locking on fixture, the thing that is locked locks and unclamps by pressure oil liquid at fixture and realizes, need not manual operation, easy accessibility, locking is reliable, efficient is high, can use manpower and material resources sparingly and the production time, thereby has very high economic worth, and because artificial intervention is few, locking is firm, so the operation of straightener is more safe and reliable, and the present invention is simple in structure in addition, easy operating is safeguarded, easy to use, good market prospects are arranged.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is that the master of hydraulic locking apparatus of the present invention looks the sectional structure schematic diagram;
Fig. 2 is the perspective view of hydraulic locking apparatus of the present invention.
The specific embodiment
The exemplary embodiments that embodies feature ﹠ benefits of the present invention will be described in detail in the following description.Be understood that the present invention can have at different embodiment various variations, its neither departing from the scope of the present invention, and explanation wherein and accompanying drawing be when the usefulness that explain in itself, but not in order to limit the present invention.
Such as Fig. 1 and shown in Figure 2, hydraulic locking apparatus of the present invention is used for the walking beam 7 of top roll box 8 lockings at straightener, and quantity can be cover or two covers, also can be that many covers are used, and is unrestricted, determines according to actual needs.The present invention includes cylinder barrel 1, seal group 2, piston 3, with the pull bar 4 of T connector 41, one group of dish spring 5 and handle 6.Cylinder barrel 1 is cylindrical shell, is fixed on the bearing 12 by bolt 11, and this bearing 12 is weldingly fixed on the walking beam 7 of straightener.Piston 3 slip caps are contained in the cylinder barrel 1, and seal by seal group 2 between the cylinder barrel 1, and cylinder barrel 1 is divided into upper and lower two cavitys that do not communicate: drive oil pocket 101 and lock chambers 102.Driving oil pocket 101 is seal chamber, is communicated with hydraulic system, can come driven plunger 3 to move by pressure oil liquid.One group of dish spring 5 of lock chambers 102 interior suits, when pressure oil liquid driven plunger 3 moved down, dish spring 5 was compressed, carried out accumulation of energy, and when the pressure oil liquid oil return, dish spring 5 releases energy, and the restoring force driven plunger 3 of generation moves up.
By bolt one holder 9 is installed on the walking beam 7 of straightener, holder 9 position placed in the middle between bearing 12 and fixture block 81.Holder 9 is processed with manhole on vertically, and the support section turning set of handle 6 is contained in the manhole of holder 9, and the top of handle 6 is a boss, so that handle 6 reliably is installed in the holder 9.Extend an operating side on the projection section of handle 6, to make things convenient for rotating operation.The endoporus of handle 6 is square through hole, and pull bar 4 passes the square through hole of handle 6, and corresponding part also is square outer rim 42, to cooperatively interact, is convenient to by handle 6 rotating tension bars 4, and turning handle 6 can drive pull bar 4 90-degree rotations.
When the walking beam 7 locking top roll box 8 of straightener, pressure oil liquid moves down by driving oil pocket 101 driven plunger 3 of cylinder barrel 1, thereby driving the pull bar 4 that is connected with piston 3 moves down, while dish spring 5 compressed larger strokes, savings spring-go potential energy, this moment, the T connector 41 of pull bar 4 was parallel with sulculus hole 801 opening directions on the fixture block 81, under the pressure oil liquid continuous action, T connector 41 passes sulculus hole 801 and enters in the large slotted eye 802, this moment, turning handle 6 made pull bar 4 90-degree rotations, make T connector 41 vertical with sulculus hole 801 opening directions, then carry out off-load to driving oil pocket 101, restoring force driving lower link 4 at dish spring 5 moves up, until leaning large slotted eye 802, T connector 41 is communicated with on the cell wall in sulculus hole 801, the restoring force of dish spring 5 discharges fully at this moment, therefore can be with 8 lockings of top roll box on the walking beam 7 of straightener.
When the walking beam 7 of straightener is removed top roll box 8, to driving charged pressure fluid in the oil pocket 101, so that driving pull bar 4, piston 3 moves down, T connector 41 separates with the cell wall of large slotted eye 802, rotary handle 6, so that T connector 41 is parallel with sulculus hole 801 opening directions on the fixture block 81, then carry out off-load to driving oil pocket 101, restoring force driving lower link 4 at dish spring 5 moves up, until pull bar 4 is thrown off draw-in groove 80 fully, be positioned at fixture block 81 tops, this moment, top roll box 8 was thrown off with the walking beam 7 of straightener.
Beneficial effect of the present invention is, the present invention compared with prior art, use the pull bar 4 clampings thing 8 that is locked among the present invention, pull bar 4 relies on the piston 3 that links to each other to drive by the pressure oil liquid that drives oil pocket 101, and the restoring force by spring 5 will be locked thing 8 lockings on fixture 7, the thing 8 that is locked locks and unclamps by pressure oil liquid at fixture 7 and realizes, need not manual operation, easy accessibility, locking is reliable, efficient is high, can use manpower and material resources sparingly and the production time, thereby has very high economic worth, and because artificial intervention is few, it is reliable and stable to lock, so the operation of straightener is more safe and reliable, and the present invention is simple in structure in addition, easy operating is safeguarded, easy to use, good market prospects are arranged.
Technical scheme of the present invention is disclosed as above by preferred embodiment.Those skilled in the art should recognize change and the retouching of doing in the situation that does not break away from the scope and spirit of the present invention that the appended claim of the present invention discloses, all belong within the protection domain of claim of the present invention.
