Mouthful) it is transported to the transporting equipment that continues, and by the transporting equipment that continues by Coal Transport to appointed place；When the transporting equipment that continues
When aircraft tail shelf (rewinding mouth) is relatively low, jack 300 is shunk and drives mobile square chest 200 to move vertically downwards, so as to,
The headstock 500 in supporting plate 400 and supporting plate 400 is driven to move down certain distance by mobile square chest 200, and then, equally
The height of the headstock 500 (discharge port) of Coal Transport machine is set to be more than the height for transporting equipment aircraft tail shelf (rewinding mouth) that continue, with
It is easy to coal being transported to and continues on transporting equipment, and further by Coal Transport to appointed place.
A kind of height-adjustable door frame that the present embodiment provides can adjust Coal Transport in the presence of jack 300
The actual height of the headstock 500 (discharge port) of machine, enable adaptation to the aircraft tail shelf (rewinding mouth) of the various transporting equipments that continue
Highly, and the headstock 500 (discharge port) of Coal Transport machine is caused highly to be more than the transporting equipment aircraft tail shelf (rewinding mouth) that continues
Highly, eventually through transporter, the transporting equipment that continues by Coal Transport to appointed place.Therefore, height-adjustable door is passed through
Frame can realize the height regulation of headstock 500 (discharge port), and then expand the range of choice for the equipment that continues, and make the equipment that continues
Selection it is no longer limited, reduce further input cost.
In the optional technical scheme of the present embodiment, mobile square chest 200 is arranged to 4, and four mobile square chests 200 are evenly arranged
Opening position in the lower surface of supporting plate 400 close to edge.
Fixed and connected using welding manner in the optional technical scheme of the present embodiment, between mobile square chest 200 and supporting plate 400
Connect.
It should be noted that considering stability problem, four are secured on the lower surface of supporting plate 400 in the present embodiment
Mobile square chest 200, and four mobile square chests 200 are in be evenly arranged, so, by jack 300 respectively to four movements
Square chest 200 is supported, and when the headstock 500 of transporter needs to adjust height, each jack 300 extends or shunk, and enters
One step drives mobile square chest 200 vertically to move up and down, and then synchronous drive supporting plate 400 is vertically done smoothly
Motion, to realize the purpose for adjusting height.
Further, the top of mobile square chest 200 is fixedly connected with the bottom of supporting plate 400, can specifically use weld,
The modes such as riveting, threaded connection, specifically, using welding manner in the present embodiment, but are not limited to use welding manner.
