The specific embodiment

Like Fig. 1～shown in Figure 6, use the double-chain conveyor of the chain assemblies of the utility model, the chain 5 that comprises actuating device 1, drives by actuating device 1, on the sled throughput direction to the conveying frame 10 of chain 5 guiding, support the bracing frame 9 of carrying frame.Actuating device 1 is fixed on baker 8 belows, and the propulsion source of actuating device 1 is a motor, and chain 5 is drawn baker downwards and on the sprocket wheel of actuating device 1 and by driven by motor, moved.

Carry frame 10 to be installed in the inside of baker; The sled throughput direction of double-chain conveyor is defined as fore-and-aft direction; Carry frame 10 to comprise headstock device 2, intermediate stand 3, tailstock device 4 that front and back are fixedly connected sequentially, bracing frame 9 is to be fixed on extending on the longeron that is provided with along fore-and-aft direction of baker bottom.Said headstock device 2 directly is fixed on the longeron of baker bottom; Be respectively equipped with the sprocket wheel that cooperates with chain 5 transmissions that distributes relatively in front and back on headstock device 2, the tailstock device 4; Be fixed with on the bracing frame 9 and supply the rolling wheel support 7 of intermediate stand 3 in the fore-and-aft direction walking; Rotate on the rolling wheel support 7 and be provided with roller 71; The bottom of intermediate stand 3 is provided with to join with roller 71 friction of rollings and is incorporated on the fore-and-aft direction guiding and moves the rolling wheel guide rails 31 that cooperates, the roller running gear between rolling wheel guide rails 31 and roller 71 formation bracing frames 9 and the intermediate stand 3.The outer end of roller 71 also is provided with the flange that is used for pair roller guide rail 31 spacing guiding in addition.The road wheel 11 that tailstock device 4 is movably walking before and after being provided with on the respective roller guide rail of bracing frame 9, this road wheel 11 and corresponding rolling wheel guide rail constitute the roller running gear between bracing frame 9 and the tailstock device.

Intermediate stand 3 in the foregoing description provides main support for carrying frame 10, and respectively between intermediate stand 3 and the bracing frame 9, be provided with the roller running gear between tailstock device 4 and the bracing frame 9.Certainly in other embodiment of the utility model; Just can satisfy the support requirement if only the roller running gear is set in one of them of intermediate stand 3 or tailstock device 4; The part of such roller running gear just can only be arranged on one of them of intermediate stand 3 or tailstock device 4; Corresponding mating part is set on bracing frame gets final product, and in other embodiment of the utility model, can the position that be provided with of roller and rolling wheel guide rails be exchanged as required.

Carry being provided with that front and back are connected on headstock device 2, intermediate stand 3, tailstock device 4 on the frame 10 along the chain guide 13 of two confession chains, 5 walkings of fore-and-aft direction extension; Chain guide 13 and chain 5 are formed the embodiment of the chain assemblies of the utility model; The structure of chain guide 13 is shown in the cross section at intermediate stand 3 places of Fig. 3; Every chain guide 13 comprises two side guide plates 131 that are symmetricly set in corresponding chain 5 both sides and is fixed in two supporting plates 132 between the side guide plate 131; The both sides guide plate has the block facade that cooperates with chain 5 towards in opposite directions; Supporting plate 132 corresponding every chain 5 levels link configuration are and two-layer about having, and every layer of supporting plate 132 has two holding faces up that are set up in parallel.The bilateral symmetry of said chain 5 each chain link is rotatably equipped with the carrying roller 53 on the holding face that is supported in corresponding supporting plate 132 that rolls; The bilateral symmetry of said chain 5 each chain link is rotatably equipped with the track adjusting wheel 52 of rolling and cooperating with the block facade of said side guide plate 131; The side guide plate makes that to the chain guiding chain operation is more steady, can make running velocity adopt variable frequency control to regulate.The top of chain 5 each chain link is equipped with the carriage 51 that is used to support and drive skid 12 operations; Carriage 51 has two kinds of forms; As shown in Figure 3; Carriage 51 both sides of the edge on right side have clamping sled 12 play directional tagging turn edge, the carriage in left side does not then have, and can on carriage, all be provided with in other embodiments certainly to turn edge yet.Article two, chain guide 13 relative dual-side place in the outer part arranges that along the fore-and-aft direction transpostion interval promising skid 12 provides two row's guiding edger rolls 54 of guiding.

And two chain 5 correspondences are set around on two sprocket wheels of tailstock device 4, are connected with the weight-driven 6 that is used for tension chain respectively on two sprocket wheels of tailstock device 4, thereby avoid the phase mutual interference.The structure of weight-driven 6 belongs to prior art, no longer details here.
