Abstract
The invention relates to a hydraulic rapid locking device for an oil film bearing. The locking device comprises a short pattern hydraulic cylinder, a locking plate, a square key, a snap ring assembly etc., wherein the short pattern hydraulic cylinder comprises a cylinder sleeve, a piston, a cylinder cover, a nut, a sealing and a quick-change joint, etc. The locking device is characterized by changing a machinery locking into a hydraulic locking, wherein an original roller structure is maintained, and the machinery locking is changed into the hydraulic locking by utilizing present space; and a locking nut and a volution are omitted to change into a short pattern hydraulic cylinder structure. While loading and unloading of the oil film bearing, the quick-change joint on a hydraulic tool is connected to the short pattern hydraulic cylinder to start the hydraulic tool; pressure oil enters into a locking oil pocket or a dismounting oil pocket; and a locking pressure and a dismounting pressure are controlled quantificationally to complete bearing locking or dismounting. The locking device has effects of convenient loading and unloading, accurate quantification, rapidness and safety.
Description
Technical field
The present invention relates to filmatic bearing, particularly the hydraulic locking apparatus of filmatic bearing.
Background technique
The locking device of filmatic bearing is that the load-bearing member with filmatic bearing is locked on the roll, guaranteeing the normal operation of bearing unit, and according to the requirement of grinding roller and maintenance, regularly filmatic bearing is disassembled from roll.Locking device in use requires handling safety, convenient, fast.
As shown in Figure 1, existing locking device is the mechanical interlocking structure, mainly is made up of locking nut 1, volution 2, clamping bolt 3, latch 4, square key 5, snap ring assembly 6; Locking nut 1 is through screw thread and volution 2 matched togethers; Square key 5 is loaded among the roll 7 keyway 7-1 and embeds in the volution 2 interior hole slots, and to stop volution 2 rotations, snap ring assembly 6 is sleeved among the roll 7 end grooves 7-2; Latch 4 is installed between locking nut 1 and the volution 2; Clamping bolt 3 links together locking nut 1, volution 2, latch 4, and the locking effect is played in the mutual rotation of constraint locking nut 1 and volution 2.During locking, wire rope is wrapped on the locking nut 1, uses travelling crane (driving) the pulling wire rope in workshop, impel locking nut 1 to rotate, promote other correlated parts and move axially, when the suspension hook of travelling crane spinned, expression locking put in place.During dismounting, need equally wire rope is wrapped on the locking nut 1, with the reverse pulling of driving wire rope, rotation lock nut 1 promotes correlated parts and moves axially, and bearing is disassembled from roll.It is not enough and shortcoming is: coupling mechanism force can't quantitatively be controlled, and can only rely on workman's working experience to judge, filmatic bearing is locked on the roll; Locking, disassembling section complicacy; It is longer to take the travelling crane time during mounting or dismounting, and mounting or dismounting need artificial experience to judge, have potential safety hazard.
Summary of the invention
The objective of the invention is to overcome the deficiency and the shortcoming of existing technology; And make improvements, under the constant situation of former roll structure, utilize existing space; Change mechanical interlocking into hydraulic pressure and lock fast, quantitatively control the coupling mechanism force of locking device when installing and removing filmatic bearing to be implemented in.
The technical solution that realizes above-mentioned purpose is:
Filmatic bearing hydraulic pressure quick-locking device comprises latch 4, square key 5, snap ring assembly 6, clamping bolt 3, it is characterized in that: this locking device also comprises short type oil hydraulic cylinder; Described short type oil hydraulic cylinder comprises cylinder sleeve 8-1, piston 8-2, cylinder cap 8-3, nut 8-4, liner packing 8-5, piston seal 8-7, cylinder cap sealing 8-11, quick release coupling 8-9; Described cylinder sleeve 8-1 endoporus is provided with two pass liner packing 8-5, and cylinder cap 8-3 endoporus is provided with single track cylinder cap sealing 8-11, and the oilhole 8-10 that connects two oil pockets is set; Piston 8-2 endoporus is provided with keyway; Described cylinder sleeve 8-1, piston 8-2, cylinder cap 8-3, and liner packing 8-5, piston seal 8-7 fit together and form two oil pockets with cylinder cap sealing 8-11, promptly lock oil pocket 8-6, dismantle oil pocket 8-8; Described square key 5 is packed in the piston 8-2 keyway; Snap ring assembly 6 is made up of two semi-rings; And connecting groove is set is sleeved on the roll 7, forming the roll shoulder, latch 4 is installed in nut 8-4 end face and the piston 8-2 end face groove; Clamping bolt 3 links together latch 4, nut 8-4, cylinder cap 8-3, piston 8-2, retrains the mutual rotation between them.
The present invention compared with prior art under the constant situation of former roll structure, changes the mechanical interlocking structure into oil hydraulic cylinder quick locking mechanism, has accurate, quick, the easy to operate and safety of loading and unloading, quantitatively controls advantages such as coupling mechanism force.
