Specific embodiment
The present invention will be further described below with reference to the accompanying drawings.
As shown in Figure 1, a kind of speed of highwall mining connects delivery unit, including frame body 1, driving drum 2, decelerating motor 3 change
To roller 4, quick change connection device 5, automatic tension device 6, steel wheel unit 7, electric cabinet 8, idler assembly 9, the groups such as conveyer belt 10
That decelerating motor drives driving drum at, the operational process of delivery unit, driving drum driving conveying belt again, will a upper transport singly
Head of the coal of member from tail portion to delivery unit, then pass it on next delivery unit, thereby realize the continuous fortune of coal
Defeated, electric cabinet realizes the start and stop of delivery unit belt by remotely controlling, and fast replacing device is realized between two delivery units
Quick connection, tension device is to carry out in real time belt into its skidding is prevented, and steel wheel unit is dragged in delivery unit
It plays a supporting role when walking, idler assembly is the necessary composition of belt conveyor.
Each component of Fig. 2 and frame body connection schematic diagram, decelerating motor 3 are connected with driving drum 2, and driving drum is solid by bolt
It is scheduled on frame body, bend pulley 4 is bolted on the both ends of frame body, and steel wheel unit 7 is solid by bolt with steel wheel briquetting 18
It is scheduled on the bottom of frame body, idler assembly is placed at the respective card slot of frame body.
Shown in Fig. 3, return idler and frame body connection schematic diagram, return idler 19 are fixed under frame body by U-shaped card 20
In portion's card slot.
Shown in Fig. 4, the exploded view of quick change connection device, quick change connection device includes front end engaging lug 11, rear end
Engaging lug 12, connecting pin 13 and fast inserted block 14, front end engaging lug 11 and rear end engaging lug 12 are separately positioned on the two of frame body 1
End, even delivery unit is connected the speed of two neighboring outdoor highwall mining by front end engaging lug 11 and rear end engaging lug 12, described
Front end engaging lug 11 on the groove that is provided with the circular hole I22 that connecting pin 13 can be allowed to pass through and fast inserted block 14 can be allowed to be inserted into
21, circular hole I22 and 21 right-angled intersection setting of groove and circular hole I22 pass through groove 21, and the rear end engaging lug 12 includes setting
The otic placode of two sides is connected by pin shaft between the otic placode of two sides, and pin shaft is stuck in groove 21, and fast inserted block 14 is inserted in groove 21 simultaneously
It is interior, circular hole II23 corresponding with circular hole I22 is provided on fast inserted block 14, connecting pin 13 is inserted in circular hole I22 and circular hole II23, behaviour
First two delivery units are docked end to end when making, i.e., it is single the rear end engaging lug 12 of a upper delivery unit to be directed at next transport
The front end engaging lug 11 of member, is laterally inserted into fast inserted block 14, then fast bolt axle 13 is passed to the pin of front end engaging lug 11 from top
In axis hole, just two delivery units are connected at this time.
Fig. 5 is the cross-sectional view of quick change connection device, since the connection between speed even delivery unit needs to connect rapidly, and
Guarantee enough intensity, fast inserted block 14 is introduced in the design, guarantees that delivery unit stress of pin shaft when drawing and pushing away all is
Face contact, and delivery unit has certain swing angle between two delivery units at uneven tunnel or climb and fall,
The size of pivot angle is exactly that the angle of fast inserted block is leaned on to limit.
Fig. 6 is tensioning apparatus and frame body connection schematic diagram, Fig. 7 are automatic tension device structural schematic diagram.Skin as shown in Figure 7
It being formed with automatic tension device by Electrohydraulic push rod 15, attachment base 16 and into roller 17, Electrohydraulic push rod 15 is connected with attachment base 16,
Attachment base 16 is connected with into roller 17, and slideway of the attachment base 16 on frame body slides.When work simultaneously by two Electrohydraulic push rods
Release and retract realize belt into, pressure sensor is installed to detect the size of tensile force inside electric putter 15, into
And determine whether oil cylinder needs to continue to stretch out according to pressure size, to increase tensile force.Entire transportation system also sets up simultaneously
Belt speed measurement sensor, once transport belt slippery can detected in time.Specific control mode is to set two in a program
Kind control model works normally and skids.
One, sequence under normal circumstances is system detection pressure sensor pressure, if not up to setting value, illustrates
Tensile force is inadequate, needs to continue to extend oil cylinder and realizes tensioning, when reaching setting value, electric putter motor stalls, and hydraulic lock
Self-locking, belt runs well.
Two, when skidding, electric drum is to run well first, and the belt speed of belt speed sensor detection at this time is abnormal, illustrates to skid,
It needs to be tensioned at this time, the rotation of electric putter motor pushes piston rod tensioning, after detecting that belt speed is normal, gives in a program at this time
Certain delay makes to pass through conveyer compared with gathering coal, is then being restored to the value of normal pressure sensor settings (due to mistake
Big tension can reduce the service life of entire transportation system, it is therefore desirable to set certain belt tension value, meet operation
Under the premise of it is the smaller the better), until electric putter retract, when reaching pressure sensor setting value stop electric putter shutting down, it is hydraulic
It locks self-locking.It thus can be very good the skidding of processing conveyer.
