Abstract
The utility model discloses a sealing device for a hydraulic cylinder of a gyratory crusher, relating to a gyratory crusher and solving the technical problems of up-down shifting and poor sealing effect of the traditional sealing device. The sealing device disclosed by the utility model comprises a hydraulic cylinder plunger and a hydraulic cylinder bushing and is characterized by further comprising a clamping plate, a clamping plate fixing ring, a V-shaped combined sealing ring, a bolt and a locking gasket, wherein the clamping plate is arranged on a cylinder cover by means of self gravity, the V-shaped combined seal ring is arranged in a groove of the clamping plate, the clamping plate fixing ring is arranged on the V-shaped combined seal ring, and the clamping plate fixing ring is fixed on the clamping plate through the bolt and the locking gasket. The sealing device is used for the gyratory crusher; and the V-shaped combined seal ring is firmly fixed by the clamping plate so as to reduce up-down shifting, not only is the sealing property of hydraulic oil improved, but also the service life of the seal ring is also prolonged, the replacement frequency is reduced, and the production efficiency of equipment is improved.
Description
Technical field
The utility model relates to gyratory crusher, the hydraulic oil seal arrangement of particularly large-scale gyratory crusher oil hydraulic cylinder.
Background technique
In the working procedure of large-scale gyratory crusher, main shaft is done the swivel feeding motion under the support of cylinder plunger and thrust bearing, thereby realizes the fragmentation of material.Be installed in the position that alignment sensor on the oil hydraulic cylinder cover plate is used for monitoring main shaft, when main axis jerking, clamping panel, plunger, plunger wearing plate, thrust bearing fit tightly with main shaft is in the same place, and prevents separately and damages.Need to install the hydraulic oil seal arrangement between the plunger of oil hydraulic cylinder and the cylinder cap, sealed mouth is arranged in the middle of the hydraulic oil seal arrangement, the main shaft alignment sensor is installed.This seal arrangement and cylinder plunger fit tightly, and have only excellent sealing performance, just can seal the deadweight and the crooked immense pressure that is produced of extruding of main shaft and material, keep the disintegrator proper functioning.Mainly there is the problem of play up and down of oil sealing in present seal arrangement, and sealing effect is bad.
Summary of the invention
The purpose of the utility model is intended to overcome the shortcoming of existing technology, and a kind of seal arrangement of gyratory crusher oil hydraulic cylinder is provided, and solves existing sealing play up and down, the technical problem of sealing effect difference.
The utility model is realized through following technological scheme:
The seal arrangement of gyratory crusher oil hydraulic cylinder; Comprise: cylinder plunger and oil hydraulic cylinder lining; It is characterized in that: said seal arrangement is made up of clamping panel, clamping panel retaining ring, V-type combined seal ring, bolt and lock washer, and said clamping panel is installed in above the cylinder cap by deadweight, and said V-type combined seal ring is installed in the groove of clamping panel; Said clamping panel retaining ring is installed in above the V-type combined seal ring, and said clamping panel retaining ring is fixed on the clamping panel by bolt and lock washer.
The utility model and existing technology relatively because seal arrangement has the clamping panel retaining ring, its with the sliding up and down in the process of plunger; Make the clamped plate retaining ring of V-type combined seal ring firmly fixing, reduced play up and down, not only improved the sealability of hydraulic oil; Better keep the proper functioning of disintegrator, more can prolong the working life of seal ring, reduce and change number of times; Improve efficiency of equipment, reduce the maintenance cost of equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The utility model is further described through preferred embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1; A kind of seal arrangement of gyratory crusher oil hydraulic cylinder; Be made up of clamping panel 1, clamping panel retaining ring 2, V-type combined seal ring 3, bolt 4 and lock washer 5, said clamping panel 1 is installed in above the cylinder cap by deadweight, and said V-type combined seal ring 3 is installed in the groove of clamping panel; Said clamping panel retaining ring 2 is installed in above the V-type combined seal ring 3, and said clamping panel retaining ring 2 is fixed on the clamping panel 1 by bolt 4 and lock washer 5.
During the utility model work, drive it by cylinder plunger (6) and in cylinder body, move up and down, bear the deadweight and the crooked immense pressure that is produced of extruding of main shaft and material simultaneously along oil hydraulic cylinder lining (7).
