A kind of elevating conveyor security closure, comprises upper frame, underframe and wire lath; Upper frame comprises the first back timber, the first bottom girder, the first left side beam and the first right side beam, and the first back timber and the first bottom girder are straight beam, and the first left side beam and the first right side beam are all the curved beams being connected in sequence by horizontal beam, cant beam, vertical beam; Underframe comprises the second back timber, the second bottom girder, the second left side beam and the second right side beam, and the second back timber, the second bottom girder, the second left side beam and the second right side beam are all straight beam; The second back timber of the first back timber, the first bottom girder and the underframe of upper frame, the length of four beams of the second bottom girder all equate, and are bolted between the first bottom girder of upper frame and the second back timber of underframe; Wire lath covers and is fixed on upper frame and underframe.
When use, the utility model device is arranged on to the lap-joint of elevating conveyor afterbody and scraper conveyor head, the second bottom girder of underframe in the utility model is connected on chute spillplate by the screw of M20.
Further, between the first back timber and the first bottom girder on upper frame, between the first left side beam and the first right side beam, be all fixed with respectively band iron lacing wire; Between the second back timber on underframe and the second bottom girder, be also fixed with band iron lacing wire.The firm stable that band iron lacing wire not only can strengthen framework is set, and can also guarantee fund belongs to the smooth of net.
The first back timber, the first bottom girder, the first left side beam and the first right side beam on upper frame all adopt 45 steel angle structures; The second back timber, the second left side beam and the second right side beam on underframe all adopt 45 steel angle structures, and the second bottom girder adopts 80 steel angle structures.It is for guarantee again can be too not heavy sufficient intensity in the situation that the first back timber, the first bottom girder, the first left side beam, the first right side beam, the second back timber, the second left side beam, the second right side beam all adopt 45 steel angle structures.It is the strength demands in order to meet upper frame gravity torque that the second bottom girder adopts 80 steel angle structures, is also for attractive in appearance simultaneously.Meanwhile, upper frame and underframe all adopt colliery conventional protect top wire lath can not only weight reduction, but also can see the situation of producing coal of key position, prevent to reprint the stuck accident of chain and coarse coal.
The beneficial effects of the utility model are:
1) this device has enough intensity, can in the time there is all kinds of easy accident, guarantee the safety of periphery personnel and ancillary service;
2) this device is totally-enclosed and total quality is light, alleviate the weight of elevating conveyor entirety, make the frictional force between elevating conveyor and base plate not exceed pulling force and the elevating conveyor walking end fixture of slide fastener and the frictional force of base plate of reprinting jack, guaranteed the normal walking of elevating conveyor;
3) after this device dismounting, single-piece size is little, facilitates its transportation and installation;
4) this device installation, convenient disassembly, be convenient to maintenance repair and the maintenance of elevating conveyor;
5) this device meets the demand of scraper conveyor head and the relative motion of reprinting afterbody lap-joint;
6) the utility model device is made easily, with low cost, simple to operate, can promote the use of on a large scale, and be economic and practical type product.
