At present, the planisher that more domestic large-size stainless steel manufacturing enterprises go into operation be mostly introduce from DMS Bliss company of the U.S. BLISS corrosion-resistant steel planisher, the effect of planisher is to make to have good plate shape and higher surface finish with steel.In the gauge and shape control system of BLISS corrosion-resistant steel planisher, servo-cylinder is the core component of this system.Its effect is to align stroke and the position of leveling roll, makes upper and lower leveling roll keep certain gap (adjusting roll gap), controls rolling thickness and the plate shape of steel plate.Reach the job requirement of above high precision, high response, just must ensure the favorable sealing property of oil cylinder inside and outside, metal parts is without inordinate wear.Therefore the regular off-line reparation of planisher servo-cylinder and detection are the necessary projects that ensures unit function precision.
But overhaul in operation at current BLISS planisher servo-cylinder, because not designing lifting point on this cylinder block and the larger weight of this oil cylinder volume is heavier, meanwhile be subject to the restriction of working space, therefore the dismounting task difficulty of this oil cylinder is very large and have many potential safety hazards.Because oil cylinder is cylindrical shape, the conventional suspenders such as suspender belt, steel rope cannot reliably be fixed and lift by crane.
The current suspender for oil cylinder, as the Chinese utility model patent " hydraulic oil cylinder of press dismounting suspender " that the patent No. is CN201120441360.7, comprise hanger, hanger is welded on cylinder body terminal pad, on cylinder body terminal pad, be provided with bolt hole, its center, lower surface welding piston is fixed leading screw.This suspender is that the terminal pad of suspender is provided with bolt hole by being connected with cylinder body and the piston of hydraulic ram, dismantling and install, being provided with mounting hole on cylinder body.This structure can only be used for corresponding oil cylinder, if do not have corresponding mounting hole just can not load and unload on cylinder body.Therefore for the contour structures of planisher servo-cylinder, need to design quick and convenient, the safe and reliable suspender of a kind of dismounting, the oil cylinder being embedded in body can be hung out fast.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, dismounting quickly and easily for the dismounting suspender of corrosion-resistant steel planisher servo-cylinder for the above-mentioned state of the art, can carry out safe and reliable lifting to such servo-cylinder.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of dismounting suspender for corrosion-resistant steel planisher servo-cylinder, is characterized in that this dismounting suspender comprises:
One crossbeam, the upper center of crossbeam is welded with a hanger;
Two upper arms, are removably vertically set in respectively the left and right sides of crossbeam, the lower end of upper arm be welded with match with the cylinder body inner concave of oil cylinder for hitching the support hook portion of cylinder body.
As improvement, described crossbeam adopts length to be greater than the channel-section steel of cylinder block diameter, offers respectively the knock hole for fixing upper arm in the left and right sides of crossbeam.
As improvement, described knock hole is at least symmetrical each one, and the distance between the knock hole of two of left and right is consistent with the diameter of cylinder body.
Improve again, the cross section of described upper arm is L-shaped, and the vertical portion of upper arm is to adopt rectangular steel pipe, offers the square aperture matching with crossbeam in the upper end of rectangular steel pipe, upper arm hangs on crossbeam by square aperture cover, is provided with the through hole corresponding with knock hole in the both sides, front and back of square aperture.
Improve, described support hook portion is trapezoidal steel plate again, is equipped with the pad for increasing friction force at the upper surface that supports hook portion.
Compared with prior art, the utility model has the advantage of: all parts of suspender all can split combination easily, when lifting, as long as two upper arms are set on crossbeam, support hook portion and be connected in the inner fovea part of oil cylinder, utilize cucurbit to hang with steel rope and just oil cylinder can be hung out fast.The utility model is simple in structure, dismounting is quick and convenient, can lift safely and reliably corrosion-resistant steel planisher servo-cylinder, avoid the Peril Incident causing due to oil cylinder landing in lifting process to occur, effectively shortened production time, increase work efficiency, ensured normally carrying out of production.

Fig. 1 is the STRUCTURE DECOMPOSITION figure of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment under use state.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, 2, the dismounting suspender for corrosion-resistant steel planisher servo-cylinder of this enforcement, comprise two upper arms 2 in crossbeam 1 and left and right, crossbeam 1 is to adopt channel-section steel to make, length is greater than the diameter of cylinder of oil cylinder 4, be welded with a hanger 3 in the upper center of crossbeam 1, hanger 3 is provided with the lifting hole(eyelet) that the steel rope that hangs with cucurbit is connected, upper arm 2 is removably vertically set in the left and right sides of crossbeam 1, the cross section of upper arm 2 is L-shaped, the lower end of upper arm 2 is welded with the support hook portion 21 matching with the cylinder body inner concave of oil cylinder 4, the vertical portion of upper arm 2 adopts rectangular steel pipe, offer the square aperture 23 matching with crossbeam 1 in the upper end of rectangular steel pipe, offer respectively the knock hole 11 for fixing upper arm 2 in the left and right sides of crossbeam 1, knock hole 11 is at least symmetrical each one, distance between two knock holees 11 in left and right is consistent with the diameter of cylinder body, both sides, front and back in the square aperture 23 of upper arm 2 are provided with the through hole corresponding with knock hole 11 24, upper arm 2 hangs on crossbeam 1 by square aperture 23 covers, snap in after the inner concave of oil cylinder 4 when supporting hook portion 21, pass through hole 24 by bolt, knock hole 11 is located upper arm 2, avoid rocking of upper arm 2, supporting hook portion 21 is trapezoidal steel plate, so just large with the contact surface of oil cylinder, in addition, be equipped with the pad made from rubber 22 for increasing friction force at the upper surface that supports hook portion 21.
