This system operating principle as follows:
With reference to shown in Fig. 1, finished product material transport vehicle 2 is connected with hoist engine 41 by wire rope 42, pulley 43, and hoisting mechanism 41 drives and drives finished product material transport vehicle 2 to slide along track 3.Hot encoder 6 is arranged on hoist engine 41, and hoist engine 41 drives and drives Hot encoder 6 to work, can indirect identification finished product material transport vehicle 2 run location on the track 3, and shows in man-machine interface.
Compound in finished product material transport vehicle 2 will will be put into reject bin 73, now triggering the 3rd proximity switch 53 and hoist engine 41 work.To suppose by the 4th proximity switch 54 of track initial point to the 3rd proximity switch 53 numerical value be presented on Hot encoder 6 of track to be 1000, then Hot encoder 6 will be set to the milestone parameter a being less than 1000, before then finished product material transport vehicle 2 goes upward to this milestone parameter a, be stage speed-raising and at the uniform velocity process; After finished product material transport vehicle 2 goes upward to this milestone parameter a and between the 3rd proximity switch 53, be moderating process; When finished product material transport vehicle 2 goes upward to the 3rd proximity switch 53 position, hoist engine 41 power-off, finished product material transport vehicle 2 stop and accepting blowing signal, and Hot encoder 6 returns and resets, and completes the up of finished product material transport vehicle 2.
After certain blowing time delay, start finished product material transport vehicle 2 downstream signal, the 4th proximity switch 54 and the hoisting mechanism 6 that now trigger track initial point work, and finished product material transport vehicle 2, before coming downwards to this milestone parameter a, is stage speed-raising and at the uniform velocity process; After finished product material transport vehicle 2 comes downwards to this milestone parameter a and between the 4th proximity switch 54, slow down descending; When finished product material transport vehicle 2 comes downwards to the 4th proximity switch 18 position, hoisting mechanism 6 power-off, Hot encoder 6 return and reset, and complete the descending of finished product material transport vehicle 2.
In like manner: on Hot encoder 6, be provided with the milestone parameter b between the 4th proximity switch 54 and the first proximity switch 51, the milestone parameter c between the 4th proximity switch 54 and the second proximity switch 52.
The specific works situation of this equipment is as follows:
During conventional initial splicing, finished product material transport vehicle 2, under the 4th proximity switch 54 control action of track 3 initial point, is placed in and stirs immediately below main building 1 discharge port, accepts the compound from stirring in main building 1:
When this bituminous mixture is defective material, the 3rd proximity switch 53 is set and is energized, now the milestone parameter a in Hot encoder 6 is worked, after a series of velocity variations process, compound is placed in reject bin 73.
When this bituminous mixture is accept, under the guidance of level-sensing device display, select the warehouse by blowing: if select, this compound is placed into the first finished product bin 71, arrange the first proximity switch 51 to be energized, now the milestone parameter b in Hot encoder 6 is worked, after a series of velocity variations process, complete blowing; If select, this compound is placed into the second finished product bin 72, the second proximity switch 52 is set and is energized, now the milestone parameter c in Hot encoder 6 is worked, after a series of velocity variations process, complete blowing.
Finished product material transport vehicle 2 when improving material, after the second limit switch 312 goes upward to the first proximity switch 51 for the protection of finished product material transport vehicle 2, unlikely slided under the effect of inertia force far away; After first limit switch 311 goes upward to the first limit switch 312 for the protection of finished product material transport vehicle 2, unlikelyly to automatically reset at the first limit switch 312, lost efficacy after slided far away; After 3rd limit switch 331 comes downwards to the 4th proximity switch 54 of track initial point for the protection of finished product material transport vehicle 2, unlikely slided under the effect of inertia force far away.
When after first, second finished product bin is filled or bituminous mixture by transport vehicle when stirring under main building directly splicing, start lifting mechanism 12, lower railway 33, under the effect of support guide pull bar 11 and lifting mechanism 12, upwards rotates with the pin joint of middle orbit 32.Lower railway 33 contacts the 4th limit switch 14 after rising to certain altitude, triggers described 4th limit switch 14 and works, and drives lifting mechanism 12 power-off stopping, self-locking simultaneously.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
