Description
Technical field
The utility model relates to a kind of hydraulic swelling-up device, relates in particular to a kind of bucket elevator hydraulic cushion swelling device.
Background technology
When bucket elevator work, need to build and carry out tensioner traction in order stably normally to move, the power that tensioner produces is tension, the too little meeting of tension causes traction piece and drive wheel to skid or traction piece distortion, work mal, tension is crossed conference quickening component wear and is even run into burn-down of electric motor or driving chain fracture while overload.Present stage, each producer all adopted screw rod tensioner or two kinds of modes of weight arm, screw rod tensioner be mechanical type tensioner without buffering, after chain foot wheel abrasion, need timely adjusting, operate uncontrollable; Weight arm tensioner volume is large, and weight is large, and maintenance is adjusted inconvenient.
Utility model content
The purpose of this utility model is: a kind of bucket elevator hydraulic cushion swelling device is provided, makes gig tension have servo-actuated property, volume is little, and expanding force is large, and maintenance is convenient, long service life.
The utility model bucket elevator hydraulic cushion swelling device comprises the device dish with central through hole, the cylinder body that rear end has the axle collar is set in the central through hole of device dish, the central through hole of cylinder body cylindrical and device dish forms bearing fit, plunger axis is set in cylinder body, plunger axis coordinates formation plunger case with cylinder body, internal oil channel is set in plunger axis, internal oil channel is used for to cylinder body inner chamber supplying lubricating grease, internal oil channel is connected with external hydraulic loop through check valve by lubricating cup, adapter plate is set on plunger axis, adapter plate is arranged between the axle collar and check valve, between the axle collar and device dish, spring is set, spring has buffer action, the prepackage load of spring equals the first tension of bucket elevator driver train.
Internal oil channel does not have bending, reduces the resistance of motion of grease.
Cylinder body one end is fixedly installed positioning plate, and positioning plate is arranged on device dish outside.
Seal ring and dust ring are set in cylinder body, and seal ring and dust ring are arranged in the axle collar.
Principle of work and process: in plunger axis, inject grease by check valve, plunger axis is outer swollen, gig chain tensioner, gig is normally worked, when running into overload timer dish, power is delivered to spring, spring-compressed plays buffer action, and gig driver train is protected; Overload power disappearance rear spring tensioner, gets back to normal working.When after gig chain mild wear, device dish can be servo-actuated, continues to meet tensioner needs.
The beneficial effect that the utility model compared with prior art had is:
Bucket elevator hydraulic cushion swelling device can utilize spring potential energy to eliminate overload impact, utilizes plunger axis tensioner chain, has overload protection and prevents gig chain breakage, and simple in structure, expanding force is large, and gravity is light, is convenient to assembling, long service life.
Brief description of the drawings

Fig. 2 is right elevation of the present utility model.
In figure: 1, positioning plate; 2, bolt; 3, device dish; 4, spring; 5, cylinder body; 6, plunger axis; 7, internal oil channel; 8, the axle collar; 9, seal ring; 10, dust ring; 11, adapter plate; 12, check valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, bucket elevator hydraulic cushion swelling device comprises the device dish 3 with central through hole, the cylinder body 5 that rear end has the axle collar 8 is set in the central through hole of device dish 3, the central through hole of cylinder body 5 cylindricals and device dish 3 forms bearing fit, the interior plunger axis 6 that arranges of cylinder body 5, plunger axis 6 coordinates formation plunger case with cylinder body 5, the interior internal oil channel 7 that arranges of plunger axis 6, internal oil channel 7 does not have bending, internal oil channel 7 is for to cylinder body 5 inner chamber supplying lubricating greases, internal oil channel 7 is connected with external hydraulic loop through check valve 12 by lubricating cup, adapter plate 11 is set on plunger axis 6, adapter plate 11 is arranged between the axle collar 8 and check valve 12, between the axle collar 8 and device dish 3, spring 4 is set, spring 4 has buffer action, the prepackage load of spring 4 equals the first tension of bucket elevator driver train.
Cylinder body 5 one end are fixedly installed positioning plate 1 by bolt 2, and positioning plate 1 is arranged on device dish 3 outsides.
Interior seal ring 9 and the dust ring 10 of arranging of cylinder body 5, seal ring 9 and dust ring 10 are arranged in the axle collar 8.
By check valve 12, to the interior injection grease of plunger axis 6, plunger axis 6 is outer swollen, gig chain tensioner, and gig is normally worked, and when running into overload timer dish 3, power is delivered to spring 4, and spring 4 has compressed buffer action, and gig driver train is protected; Overload power disappearance rear spring 4 tensioners, get back to normal working.When after gig chain mild wear, device dish 3 can be servo-actuated, continues to meet tensioner needs.
In sum, the utility model makes gig tension have servo-actuated property, can eliminate overload impact, have advantages of simple in structure, expanding force is large, gravity is light, be convenient to assemble and long service life.
