The side of vehicle frame 2 and bottom surface can be sealed with shell, to reach effect attractive in appearance.
The workflow that uses this carrier to carry environmental protection brick is as follows:
(1), total power switch 24 closes, operator station is on the foot-supporting frame 21 of trailing wheel 7, both hands are handled respectively left and right handlebar 22, 20, car is started to the position that fragment of brick is stacked, then the pull-out of getting off is auxiliary argue for the sake of arguing 9 inner sleeve, from vehicle frame 2 rear ends with two front-wheels 13, 5 is fulcrum lifting vehicle frame, vehicle frame 2 is overturn forward and forms the form of fork truck, as shown in figure 10, now two jaws 14 of vehicle frame 2 front ends, 4 and hydraulic cylinder strut 18 all horizontal, two front-wheels 13 of vehicle frame 2, 5 and jaw 14, the guide wheel 15 of 4 front ends, 16 and the guide wheel 17 of hydraulic cylinder strut 18 front ends all land, by two jaws 14, 4 stretch into brick piles built on stilts bottom, the brick heap facade until sweep 1 is fitted, as shown in figure 11.
(2), the hydraulic pump power switch 26 that closes, electric hydraulic pump 36 starts to send oil by check valve 45 to hydraulic jack 3, now stop valve 25 keeps closing, return line keeps cutting off, hydraulic oil in hydraulic jack 3 promotes piston rod and stretches out, because piston rod is hinged on the middle part of hydraulic cylinder strut 18, and hydraulic cylinder strut 18 end guide wheels 17 land, under the thrust reaction of hydraulic cylinder piston rod, vehicle frame 2 can be turned over taking two front-wheels 13,5 as fulcrum, thereby automatically packs fragment of brick into two jaws 14,4 and sweep 1 forms in " L " shape loading platform. In the time that piston rod extend out to setting travel position, the normally closed travel switch 44 on hydraulic jack 3 can disconnect, and overturns thereby finish vehicle frame 2, and automatic loading is complete. Close hydraulic pump power switch 26, now hydraulic jack 3 keeps high pressure conditions under the cut-off effect of check valve 45 and stop valve 25, and piston rod keeps stretching out state. Due to before the center of gravity of car load remains on, now two front-wheels 13,5 of vehicle frame 2 and the guide wheel 17 of hydraulic cylinder strut 18 front ends form supported at three point and land, and the trailing wheel 7 of car is still unsettled, as shown in figure 12, can keep like this loading process steadily. Operator 9 can ajust car by auxiliary the arguing for the sake of arguing that presses down vehicle frame 2 rear ends, trailing wheel 7 is steadily landed, forming two front-wheels 13,5 and trailing wheel 7 supported at three points lands, as shown in figure 13, the transport of this car all keeps this holding state while advancing, now hydraulic cylinder strut 18 deflection forward, the liftoff certain distance of its end guide wheel 17, under this state, hydraulic cylinder strut 18 can also play an effect that prevents the bumper that car load tumbles forward.
(3), operator adopts the mode of " donkey of riding backwards " while transporting fragment of brick, fragment of brick is front, operator advancing and turning to rear control car. While advancing, as long as starting with speed governing, the right handlebar 20 of rotation can advance forward. As long as press reversing reversing switch 27 need to move backward time, rotate the mode that right handlebar 20 can move backward and advance. Need to turn to time, if only need slight turning to, can control trailing wheel foot-supporting frame 21 by both feet and rotate drive trailing wheel 7 deflection certain angles, can control turning to of car. When carrying out turning to or even turning around or while spin in original place of wide-angle, need to coordinate by controlling brake lever, when doing wide-angle left and turn to as needs, check left brake lever 30, the near front wheel 13 is braked, rotate right handlebar 20 and start, under the effect of differential mechanism, the left half axle 31 of differential mechanism is braked, right axle shaft 33 rotates, off-front wheel 5 is towards left to doing circular motion, and trailing wheel 7 is along with circular motion, and car load turns left. When doing wide-angle to the right and turn to as needs, check right brake lever 29, off-front wheel 5 is braked, rotate right handlebar 20 and start, under the effect of differential mechanism, the right axle shaft 33 of differential mechanism is braked, and left half axle 31 rotates, the near front wheel 13 does circular motion towards right, and trailing wheel 7 is along with circular motion, and car load turns right. Realize the brake power down function to car load, need two of left and right brake lever 30,29 to check simultaneously, due to two brake switch the 23, the 28th, the normal open switch of series connection, need to connect simultaneously and could control electric machine controller 39 motor is realized to power down function.
(4), while unloading, car is left to the position of stacking to fragment of brick, pull-out is auxiliary argue for the sake of arguing 9 inner sleeve, from vehicle frame 2 rear ends taking two front-wheels 13,5 as fulcrum lifting vehicle frame 2, lands the guide wheel 17 of hydraulic cylinder strut 18, as shown in figure 12. open stop valve 25, the hydraulic oil in hydraulic jack 3 is back to hydraulic oil container 35, hydraulic jack 3 releases through return line, piston rod is regained under the Action of Gravity Field of fragment of brick and vehicle body, travel switch 44 on hydraulic jack 3 resets closed, and fragment of brick is stacked complete automatically, as shown in figure 11. close stop valve 25, reset pulls out empty wagons and turns over. in the time the fragment of brick of the second car and the first car fragment of brick unloading need to being realized to order arrangement, the carrier of filling the second car fragment of brick is opened to the first car fragment of brick, make jaw 14, the guide wheel 15 of 4 front ends, 16 are against on the outer side elevation of the first car fragment of brick, stop and pull out auxiliary 9 the inner sleeve of arguing for the sake of arguing, from vehicle frame 2 rear ends with two front-wheels 13, 5 is fulcrum lifting vehicle frame 2, the guide wheel 17 of hydraulic cylinder strut 18 is landed, as shown in figure 12, now jaw guide wheel 15, 16 are close to the outer side elevation of the first car fragment of brick, the guide wheel 17 of hydraulic cylinder strut 18 and left and right front-wheel 13, 5 land, open stop valve 25, hydraulic jack 3 releases, piston rod is regained under the Action of Gravity Field of fragment of brick and vehicle body, jaw guide wheel 15, the 16 outer side elevations of being close to the first car fragment of brick roll downwards and promote that car load is corresponding to be retreated, front and back two car fragments of brick can be close to be piled up, thereby reach the effect of unloading that order is arranged.
