Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, large-tonnage flat bed delivery device, comprise: bracing frame 1, the head slab of bracing frame 1 is installed with support platform 2, the upper support of support platform 2 has annular arrangement rotating disk 3, some roads annular brace track 4 is provided with between described annular arrangement rotating disk 3 and support platform 2, be arranged at intervals with three road annular brace tracks 4 in the present embodiment between annular arrangement rotating disk 3 and support platform 2 from inside to outside, the quantity of annular brace track 4 can according to actual needs and the size of annular arrangement rotating disk 3 determine.Described annular brace track 4 and annular arrangement rotating disk 3 all concentrics, described annular arrangement rotating disk 3 can rotate on annular brace track 4, the structure of the per pass annular brace track 4 in the present embodiment between annular arrangement rotating disk 3 and support platform 2 comprises: be arranged on bottom annular arrangement rotating disk 3, the groove 31 and be arranged in support platform 2 and upwards recessed annular gets on the right track, and annular lower railway groove 21 recessed down, the bottom of annular lower railway groove 21 is provided with pit 22 recessed down further, evenly be covered with in annular lower railway groove 21 and have steel ball 9, the effect of pit 22 is: make to form more stable contact between steel ball 9 and annular lower railway groove 21, effectively prevent steel ball 9 play in annular lower railway groove 21, the bottom deformation in compression of annular lower railway groove 21 can also be prevented after pit 22 is set in addition, thus improve the bearing capacity of annular lower railway groove 21, lubricating oil is provided with in pit 22, lubricating oil plays actv. lubricating effect, resistance when effective minimizing steel ball 9 rolls.Spacing block 10 is provided with between adjacent steel ball 9, the structure of spacing block 10 comprises: body 101, the both sides of body 101 are respectively arranged with the spherical groove 102 for holding steel ball, body 101 offers a pair oilhole 103 connected with the spherical groove 102 of both sides, the effect of a pair oilhole 103 is the lubricating oil between the spherical groove 102 of both sides is connected, thus plays lubricating effect better.Described annular gets on the right track on steel ball 9 that groove 31 is supported in annular lower railway groove 21, and slewing circle annular rotary table 3 can drive steel ball 9 to roll in annular gets on the right track groove 31 and annular lower railway groove 21.The pair of supporting track 6 corresponding with a pair ground rail 5 is respectively arranged with in the two bottom sides of bracing frame 1, some idler wheel mechanisms 7 are all supported with between the support rail 6 of every side and ground rail 5, roller 8 in the idler wheel mechanism 7 of every side all runs and is supported between corresponding support rail 6 and ground rail 5, and the quantity of the idler wheel mechanism 7 of every side and the position distribution between support rail 6 and ground rail 5 all can ensure that the end position at forward and backward two ends bottom bracing frame 1 and midway location are supported with roller 8 all the time.In the present embodiment, the structure of each idler wheel mechanism 7 comprises: at least arrange a roller 8, and the both sides of each roller 8 are all installed with roller shaft 81, and the roller shaft 81 of roller 8 both sides is arranged on a pair adapter plate 12 respectively.The idler wheel mechanism 7 of employing said structure realizes the support to bracing frame 1, greatly can improve the bearing capacity of bracing frame 1.In the present embodiment, be provided with four rolling 8 in each idler wheel mechanism 7, the quantity of roller 8 can be arranged according to actual needs.In addition, the bottom even of the support platform 2 outside bracing frame 1 is furnished with four bottoms all near the safety post 14 on ground, the effect of safety post 14 is: once the contingency such as bracing frame 1 occurs caving in, safety post 14 can firm support on the ground, thus the situation avoiding heavy wares to drop impaired occur.
During work, a pair ground rail 5 is placed the idler wheel mechanism 7 of some.The quantity of idler wheel mechanism 7 and position distribution ensure that the end position at forward and backward two ends bottom bracing frame 1 in transport process and midway location are supported with roller 8 all the time.Heavy wares is placed on the saddle 13 on the annular arrangement rotating disk 3 at bracing frame 1 top, to front haulage bracing frame 1, pair of supporting track 6 bottom bracing frame 1 slides respectively on the roller 8 of the idler wheel mechanism 7 of both sides, roller 8 in idler wheel mechanism 7 be subject to support rail 6 to after its friction force on ground rail 5 rolls forward, it is friction of rolling between roller 8 and ground rail 5, tractive force to front haulage bracing frame 1 only need overcome roller 7 and support rail 6, and and ground rail 5 between force of rolling friction, and force of rolling friction is far smaller than force of sliding friction, therefore the tractive force for drawing bracing frame 1 can reduce greatly, thus make traction very convenient.Under the effect of tractive force, the moving velocity of bracing frame 1 is faster than the moving velocity of idler wheel mechanism 7, in order to save the usage quantity of idler wheel mechanism 7, the idler wheel mechanism be positioned at after movement on the ground rail 5 at bracing frame 1 rear can be placed on the ground rail 5 in bracing frame 1 front, thus make bracing frame 1 be transported to terminal from starting point smoothly.When heavy wares need turn to allot time, as long as slewing circle annular rotary table 3, annular bottom round turntable 3 is got on the right track on the steel ball 9 of groove 31 in annular lower railway groove 21 rotate, need to rotate the angle of alloting until turn to, very convenient, and greatly reduce heavy wares and turn to the cost alloted.
