Description
Technical field
The utility model is related to a kind of tensioning apparatus, particularly a kind of flight chain for stock ground heap reclaimer device
Tight device.
Background technology
Chain scraping mechanism in existing scraper reclaimer includes the chain of belt scraping plate, the sprocket wheel matched with chain have with
The drive sprocket positioned at one end and the driven sprocket positioned at the other end that drive mechanism connects, are installing the driven chain of driven sprocket
There is the tensioning apparatus of adjustment chain elasticity between wheel shaft and tailstock.
Existing tensioning apparatus has following several conventional structure types：
One kind is screw rod plus plate tower spring tensioning, manual form.This tensioning form is simple, belongs to mechanical tensioning, by people
Regulation of the work to screw rod top nut carries out the adjustment of tensile force, inconvenient operation；
One kind is that glycerine oil cylinder is tensioned, manual form, and manually pump is suppressed.Although this tensioning form is simple, adopt
It is glycerol medium, and glycerine is more sticky, pressure is not easy collection, therefore tensile force is uncontrollable.
The content of the invention
The purpose of this utility model is to provide the scraper plate that a kind of simple structure, tensile force are controllable, easy to operate, voluntarily adjust
Chain stretching device.Overcome the deficiencies in the prior art.
Flight chain tensioning apparatus of the present utility model, including driven chain wheel shaft and tailstock, at the two ends of driven chain wheel shaft
Driven sprocket is provided with by bearing, tensioning apparatus is provided between driven chain wheel shaft and tailstock, described tensioning apparatus has two
Group and Parallel Symmetric setting, the structure of described tensioning apparatus are as follows：Slideway is set in the termination of tailstock, with slideway mutually equipped with cunning
Block, on described driven chain wheel shaft, the external end head of the piston rod matched with oil cylinder passes through bearing pin and described cunning to slide block set
Block rotates connection, and the termination of oil cylinder is rotated with cylinder support by rotating shaft and is connected, and the outer sheath of cylinder support is equipped with tightening box, oil
Cylinder bearing is connected with guide rod, the end for having the butterfly spring being sleeved on guide rod, cylinder support and tightening box between guide rod and tightening box
Leaned by described butterfly spring between head.
Flight chain tensioning apparatus of the present utility model, is oil cylinder plus disc spring tension type, oil cylinder and scraper equipment during installation
The hydraulic-driven of middle claw shares 1 Hydraulic Station.Oil cylinder and butterfly spring are formed between driven chain wheel shaft and tailstock all the time after installation
Support, it is ensured that the rate of tension of chain, bag type accumulator during work in hydraulic system serves supplement to the pressure of oil cylinder
Effect, while serving certain damping, buffering effect to system.In addition combined with the disc spring in mechanical structure, further to system
Serve the supplementary function of certain energy-storage buffering.This tensioning form, pressure controllable is easy to operate simple.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is the schematic top plan view shown in Fig. 1.
Specific embodiment
As shown in Figure 1, 2：1 is the driven chain wheel shaft in scraper-type reclaimer, and 13 is tailstock, the two of driven chain wheel shaft 1

Group and Parallel Symmetric setting, the structure of tensioning apparatus are as follows：Slideway 16 parallel up and down is provided with the termination of tailstock 13, with slideway
16 are mutually furnished with sliding block 2, and sliding block 2 is sleeved on driven chain wheel shaft 1, and sliding bearing is provided between sliding block 2 and driven chain wheel shaft 1.With
The external end head of the piston rod 15 that oil cylinder 6 matches is rotated with sliding block 2 by bearing pin 4 and the turning set 3 being sleeved on bearing pin 4 and is connected,
The termination of oil cylinder 6 is rotated with cylinder support 9 by engaging lug 7 and rotating shaft 8 and is connected.The outer sheath of cylinder support 9 is equipped with tightening box
10, cylinder support 9 can be moved axially in tightening box 10, and cylinder support 9 is connected with guide rod 14, in guide rod 14 and tightening box 10
Between have the butterfly spring 11 being sleeved on guide rod 14, leaned by butterfly spring 11 between cylinder support 9 and the termination of tightening box 10.Wherein open
The termination of tight case 10 is fixedly connected by bolt and the connecting plate 12 being welded on tailstock 13 with tailstock 13.The He of oil cylinder 6 after installation
Butterfly spring 11 forms support between driven chain wheel shaft 1 and tailstock 13 all the time, it is ensured that the chain being wound on sprocket wheel has certain tensioning
Degree.This tensioning form, pressure controllable is easy to operate simple.
