The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, this load bearing trolley, comprises hand-operated mechanical platform truck 1, bearing support 2 and dolly supporting plate 3, and described hand-operated mechanical platform truck 1 comprises wheel 11, underframe 12, crane 13, crank 14, flat board 15 and screw rod 16; Described wheel 11 is arranged on underframe 12, and dull and stereotyped 15 are connected with underframe 12 by crane 13; In lifting support 13, there is the support of two parallel placements, on one of them support, have tapped bore; One end of screw rod 16 is connected with crank 14, the other end through the tapped bore on support, with tapped bore in screw-threaded engagement, and be fixedly connected with another support; By rotating the distance between two supports of crank 14 capable of regulating, thereby realize the lifting of lifting support 13, described bearing support 2 comprises the riser 22 of bearing 21 and square shape structure, the bottom of described bearing 21 is provided with two parallel heavily loaded guide rails 23, has the through hole 24 matching with fan shroud mounting hole on the upper side frame of described riser 22, lower frame, left frame and left frame; Riser 22 is vertically built up in one end of bearing 21, and is fixedly connected with bearing 21 by attaching parts 25; Described dolly supporting plate 3 is provided with two chutes 31 that match with heavily loaded guide rail 23; Described dolly supporting plate 3 is fixedly mounted on dull and stereotyped 15, and bearing support 2 is arranged on dolly supporting plate 3.
During use, as shown in Figure 2, because one end of screw rod 16 is connected with crank, the other end is through the tapped bore on a support in lifting support 13, and be fixedly connected with another support, while rotating crank 14 drive screw rod 16 rotation, can shorten or increase the distance between two supports on lifting support 13, and then realize the rising of lifting support 13 or fall, therefore can first dolly be adjusted to proper height by rotating crank 14, moved to again and needed the power unit assembly of installation or removal place, fan shroud mounting hole with heat-pipe radiator outside in the through hole 24 on screw bolt passes riser 22 and this assembly, realize being fixedly connected with of riser 22 and this assembly, then pull riser 22 that this assembly is pulled out, places on this dolly from lay down location or cabinet, then can promote dolly and this assembly be delivered to the place that needs the place of installation maybe can place, by promotion riser 22, demounting bolt, realize its installation or placement.Because the bottom of bearing 21 is provided with heavily loaded guide rail 23, so very laborsaving in the whole process that this assembly is taken out; Bearing support 2 and this inter-module are bolted simultaneously, make to have carried out rational docking between this assembly and dolly, so in this process, this assembly is not understand left and right to teetertotter, that can smooth-goingly not rock dismantles or installs this assembly, the generation that can also avoid destroying explosion suppresion surface or damage power component IGBT, has guaranteed the safety of this assembly.
As improvement of the present utility model, also can between riser 22 and bearing 21, articulation piece 26 be set, riser 22 is connected with bearing 21 by articulation piece 26, between attaching parts 25 and riser 22 and bearing 21, is bolted.While not using, can attaching parts 25 be taken off from riser 22 and bearing 21 by loose unloading bolt, by the effect of articulation piece 26, riser 22 and bearing 21 be folded, reduce it and take up room, and then convenient transportation and placement.
Preferably, fixedly mount respectively jug 27 on the left frame of described riser 22 and left frame, handled easily personnel grip pulls moving bearing support 2 and moves on dolly supporting plate 3.
