The specific embodiment
According to Fig. 1, shown in Figure 2, the utility model is made up of tension dolly 1, Electrohydraulic push rod 2, intelligent miniature controller.Tension dolly 1 is placed by roller 3 on the track of ground, and tension dolly 1 can move in orbit, and load-transfer device afterbody belt tensioning drum is fixed on the support of tension dolly 1 by bearing seat 4.Electrohydraulic push rod 2 its compositions have threephase asynchronous machine, shell and are included in hydraulic ram 5, double-direction gearpump 6, the hydraulic manifold block of shell and are connected hydraulic manifold block and the pressure oil pipe of hydraulic ram 5, hydraulic oil reservoir exists in the shell, and pressure sensor 7 is installed on the shell.Hydraulic ram 5 is made up of with Y circle, piston rod with Y circle, axle cylinder body, piston, orienting sleeve, hole.The bearing of Electrohydraulic push rod 2 is fixed on the ground, guarantees the flexible direction of piston rod of Electrohydraulic push rod 2 and the parallel track that tension dolly 1 moves during installation, and Electrohydraulic push rod 2 is connected with tension dolly 1 by fork-join head 8, connecting panel 9.
When load-transfer device need be strained, be tension force when setting pulling force, pressure sensor 7 senders, by intelligent miniature controller instruction machine operation, motor is by 6 work of coupler driven gear pump, and gear type pump 6 pressure oil output are transported to hydraulic ram 5 by hydraulic manifold block, make the piston rod retraction, drive 1 motion of tension dolly simultaneously,, play the effect of tension load-transfer device by being fixed on the afterbody belt tensioning drum tension load-transfer device on the tension dolly 1.Be to strain load-transfer device among Fig. 1, also can realize the effect of tension load-transfer device with thrust or by assembly pulley by the pulling force of Electrohydraulic push rod 2.
Hydraulic manifold block is made up of a pair of oil sucting one-way valve 10, bidirectional hydraulic lock 11, one group of overflow check valve 12 and a by pass valve 13.During threephase asynchronous machine work, by 6 work of coupler driven gear pump, gear type pump 6 is by oil sucting one-way valve 10 oil suctions, be transported to hydraulic ram 5 by bidirectional hydraulic lock 11, piston rod is moved right, pressure sensor 7 senders when reaching predetermined pull quit work by intelligent miniature controller instruction motor, the automatic pressurize locking of system.Principle and last same during reversing sense work.
In the feeding process, material can not be always uniform, and along with the increase or the minimizing of material, system pressure can increase or reduce, and promptly the degree of tightness of load-transfer device constantly can be in non-constant value.When load-transfer device is in the tension state, system pressure exceeds 20% o'clock of standard pressure value that the intelligent miniature controller sets, convert pressure to binary numeral by pressure sensor 7 and pass to the intelligent miniature controller, by the intelligent miniature controller signal is passed to Electrohydraulic push rod 2, piston rod is stretched out, at this moment load-transfer device fluffs, system pressure descends, when system pressure drops to the standard pressure value that the intelligent miniature controller sets, Electrohydraulic push rod 2 stops action, and this moment, load-transfer device was in the standard tension state.When load-transfer device was in loose state, system pressure is lower than 20% o'clock of standard pressure value that the intelligent miniature controller sets, convert system pressure to binary numeral by pressure sensor 7 and pass to the intelligent miniature controller, by the intelligent miniature controller signal is passed to Electrohydraulic push rod 2, make the piston rod withdrawal, at this moment along with the tensioning of load-transfer device, system pressure constantly increases, when system pressure increases to the intelligent miniature controller and sets pressure, Electrohydraulic push rod 2 stops action, and this moment, load-transfer device was in the standard tension state.
The load-transfer device outside is provided with sideslip switch 14, inhomogeneous because of solid accumulation in operational process, load-transfer device can be to certain one side sideslip, when load-transfer device during to left avertence, run into sideslip switch 14, sideslip switch 14 is passed to the intelligent miniature controller with signal, sends signal by intelligent miniature control, after making the certain stroke of Electrohydraulic push rod 2 withdrawals, load-transfer device moves to midway location; When load-transfer device during to right avertence, run into the sideslip switch 14 on the right, at this moment sideslip switch 14 is passed to the intelligent miniature controller with signal, sends signal by the intelligent miniature controller, makes the certain stroke of Electrohydraulic push rod 2 withdrawals, and load-transfer device moves to midway location again.
According to Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, when the load-transfer device fed distance is very long, the middle part does not have power supply again, perhaps connects power supply and can adopt a kind of middle deviation correcting device that need not power supply when inconvenient.Middle deviation correcting device is made up of hydraulic power partial sum aligning roller 15, hydraulic power partly comprises rubber roll 16, gear type pump 17 and rubber roll 16 and gear type pump 17 bonded assembly supports 18, hydraulic ram 19 and hydraulic ram 19 and aligning roller 15 support bonded assembly fork-join heads, and aligning roller 15 is to be ∪ shape by three idler pulleies 20 to install.When load-transfer device to the right during sideslip, run into rubber roll 16, load-transfer device contacts the friction force that produces and makes rubber roll 16 rapid driven gear pump 17 rotations with rubber roll 16, gear type pump 17 oil suctions are by the oil return line of hydraulic manifold block, deliver to oil cylinder 19, oil cylinder 19 promotes aligning roller 15 makes load-transfer device move to midway location, and in the time of in the middle of conveying is taken to, rubber roll 16 is in the no touch state again with load-transfer device, gear type pump 17 quits work, and oil cylinder 19 is located the self-locking packing state again.During sideslip, the correction principle is identical left for load-transfer device.Described hydraulic manifold block is made up of one group of oil sucting one-way valve 21, one group of overflow check valve 22, one group of fuel-displaced check valve 23, one group of hydraulic control one-way valve 24 and a by pass valve 25.
