Abstract
The utility model discloses a kind of improved large_sized hydraulic cylinder pin shaft structures, including pin body, L-shaped grease channel is set in pin body, the horizontal segment of the grease channel is extended through to the other end of pin body, and interior connection screw thread is respectively set in the horizontal segment both ends of grease channel.Pin shaft lubrication hole is changed to through-hole by us, do so on the one hand, when removing pin shaft we can with direct cutter along pin axis through hole direction cut, cut oxygen will not will fascinate cylinder pedestal inner hole hurt.On the other hand, liquid nitrogen can be packed into through-hole when pin shaft is installed, make pin shaft that shrinkage occur, assemble convenient for pin shaft by we.After improving, the pin assembling/disassembling time can be shortened 5 hours, and then improve the replacement efficiency for the hydraulic cylinder that fascinates.
Description
Technical field
The utility model relates to a kind of improved large_sized hydraulic cylinder pin shaft structures.
Background technique
Large_sized hydraulic cylinder be electric furnace fascinate, the key equipment of continuous caster turret unit, be the enforcement division of main equipment
Part.Because bale panoramic tables, electric furnace fascinate work under hot environment, pin shaft easily deforms abrasion, shadow when replacing hydraulic cylinder
Ring the replacement operation time.It is maintenance major project that large_sized hydraulic cylinder, which replaces one,.Hydraulic cylinder changing is fascinated hydraulic cylinder with 70t electric furnace
For probably need 48 hours, wherein connection pin shaft dismounting need nearly 40 hours.The main reason is that working environment temperature
Degree is higher, and workload is larger, and pin shaft occurs bending and deformation.Under normal circumstances with very heavy ejection, once jack beats motionless
Cutting of cutting knife pin shaft can be used, high-temperature fusion liquid-liquid can only be flowed out from one section, and used time table is longer, while easily incised wound pedestal pin hole knot
Problem is brought to assembly in conjunction face, time-consuming and laborious.Therefore, the improvement for connecting pin shaft is the key that improve cylinder replacing efficiency of fascinating
Place.
Summary of the invention
The purpose of this utility model is to provide a kind of improved large_sized hydraulic cylinder pin shaft structures, can easily be torn open
Dress improves working efficiency.
The purpose of this utility model is achieved in that a kind of improved large_sized hydraulic cylinder pin shaft structure, including pin shaft sheet
Body, is arranged L-shaped grease channel in pin body, and the horizontal segment of the grease channel is to the other end of pin body
It extends through, interior connection screw thread is respectively set in the horizontal segment both ends of grease channel.
Pin shaft lubrication hole is changed to through-hole by us, is done so on the one hand, when removing pin shaft, we can use direct cutter edge
Pin axis through hole direction cutting, cutting oxygen will not will fascinate cylinder pedestal inner hole incised wound.On the other hand, we pin shaft install when,
Liquid nitrogen can be packed into through-hole, make pin shaft that shrinkage occur, assembled convenient for pin shaft.After improving, when can shorten pin assembling/disassembling
Between 5 hours, and then improve the replacement efficiency for the hydraulic cylinder that fascinates.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the schematic view of the front view of the utility model.
Specific embodiment
A kind of improved large_sized hydraulic cylinder pin shaft structure, as shown in Figure 1, including pin body 1, setting in pin body 1
L-shaped grease channel 2, the horizontal segment of the grease channel 2 extended through to the other end of pin body, lubricating oil
Connection screw thread 3 in being respectively set in the horizontal segment both ends in channel 2, to connect liquid nitrogen pipeline.
Claims (1)
1. a kind of improved large_sized hydraulic cylinder pin shaft structure, including pin body, L-shaped lubricating oil is set in pin body
Channel, it is characterized in that: the horizontal segment of the grease channel is extended through to the other end of pin body, the water of grease channel
Connection screw thread in being respectively set in flat section both ends.
