Detailed description of the invention
See Fig. 1 to Fig. 3, the utility model relates to a kind of electric up-down mast, it comprises motor 1, motor 1 is connected to reducer 2, described reducer 2 is connected with sprocket wheel 3, the top of sprocket wheel 3 is provided with flexible guide pillar 5, described flexible guide pillar 5 is made up of Multi-section telescopic post, every section of telescopic mast is hollow telescopic mast, wherein the telescopic mast of next section is enclosed within the outside of the preceding paragraph telescopic mast, described sprocket wheel 3 is wound with chain 4, one end of this chain 4 withstands on the bottom of the telescopic mast of lowermost, described chain 4 becomes transmission vertically upward from horizontal conveyor after sprocket wheel 3 drives, thus by each section of telescopic mast in flexible guide pillar 5 one section a section upwards jack-up.
Described chain 4 is spliced by chain block 6, and chain block 6 has various structures, and preferred structure is following two kinds:
One, as Fig. 4 and Fig. 5, in the both sides, front and back of described single chain block 6, the first half of side caves inward and forms between outer land terrace 7, step surface 8 in the Lower Half of opposite side caves inward and formed, described between outer land terrace 7 is consistent with interior step surface 8 shape and can be bonded to each other, the front side of described chain block 6 has front hinge hole 9, the rear side of chain block 6 has rear hinge hole 10, in adjacent two chain blocks 6, the front hinge hole 9 of previous chain block 6 is coordinated by connector with the rear hinge hole 10 of a rear chain block 6, this connector can be bearing pin etc., when chain block 6 splices, the between outer land terrace 7 of a chain block 6 is attached on the interior step surface 8 of an adjacent chain block, just the driving chain of rigidity is constituted after all chain block splicings, such chain block 6 is when transmission, the interior step surface 8 that previous chain block 6 just can pass through promotes between outer land terrace 7 backward, thus transmit the moment of rectilinear direction, the transmission between chain block can be carried out better, between outer land terrace 7 is returned interior step surface 8 and is provided a bearing capacity upwards simultaneously, thus moving both vertically of chain 5 can be realized.
And chain block 6 can combinationally use, to increase its bearing capacity.
Embodiment one:
The inner side of chain block 6 arranges a chain block 6, two chain blocks 6 again by fixing through the bearing pin of front hinge hole 9 and rear hinge hole 10, thus a formation assembly uses, and then enhances the bearing capacity of chain block 6.
Embodiment two:
The inner side of chain block 6 arranges a chain block again, and the chain block that two chain blocks weld formation one more firm back-to-back uses, and then enhances the bearing capacity of chain block.
Two, as Fig. 6 and Fig. 7, the centre of described single chain block 6 has connecting hole 11, described connecting hole 11 is for getting up inside and outside two chain block 6 stacking splicings, chain block 6 can be combinationally used, to increase its bearing capacity, thus be applicable to the chain post transmission of more high strength, protrude in the middle part of the front side of described chain block 6 and arrange, form projection 12, the rear side medial recess of chain block 6 is arranged, form groove 13, described projection 12 is consistent with the shape of groove 13, before and after chain block 6 with the use of time, the projection 12 of a rear chain block stretches in the groove 13 of previous chain block, a rear like this chain block just can promote previous chain block and carry out parallel motion, projection 12 provides a bearing capacity upwards just to groove 13 simultaneously, thus improve the intensity of chain block 6, make chain 4 can realize moving both vertically.
Top on front side of described chain block 6 offers a front side arc-shaped notch 14, top on rear side of chain block 6 offers a rear side arc-shaped notch 15, when described front chain block and rear chain block splice, front side arc-shaped notch 14 coordinates with the rear side arc-shaped notch 15 of rear chain block and forms bearing pin through hole, and after front side arc-shaped notch 14 coordinates with rear side arc-shaped notch 15, gap is still left in both tops, if when previous chain block needs upwards to move both vertically, a front chain block just can rotate, due to the existence in the gap of two arc-shaped notch, the top of chain block can rotate, if very close to each other, the rotation of chain block can be hindered, thus limit moving both vertically of chain.
As Fig. 8, when this chain block 6 uses, splice before and after chain block 6, inside and outside two sides is all placed with the corresponding chain block arranged, bearing pin 16 is installed with in the front side arc-shaped notch 14 of two chain blocks that front and back are adjacent and rear side arc-shaped notch 15, former and later two chain blocks 6 described leave gap in place above bearing pin 16, are connected between adjacent two bearing pins 16 by chain sheet 17, the chain 4 that so just composition one is complete.
The cellular chain sheet of this driving-chain post can also be the fixing rear use of inside and outside two panels, and inside and outside two panels chain sheet is fixed by bottom transverse slat or middle bearing pin is fixed, and forms an entire combination chain block, thus adds intensity and the bearing capacity of chain post.
When this electric up-down mast uses, sprocket rotation is driven by motor and reducer, thus drive chain drive, in chain, single chain block is through particular design, chain block one joint is connect a joint and is formed by connecting, combine with next units in series, and the transmission of the horizontal and vertical of chain can be realized, thus chain is become vertical-transmission from horizontal conveyor, and then by thus by each section of telescopic mast in flexible guide pillar one section a section upwards jack-up, mast is raised to top the most at last.
Chain in this electric up-down mast is by the particular design of single chain block, chain block one joint is connect a joint be formed by connecting, combine with next units in series, the transmission of realizable force, and the one-directional rotation realizing chain block, and then the transmission of horizontal and vertical realizing chain, after chain block combinationally uses, Stability Analysis of Structures, can bear larger moment, thus makes chain form rigid transmission chain.
Electric Machine Control rigid transmission chain controls mast and stretches, and the rising or falling speed of mast can be regulated, and can reach speed faster, and rising or falling speed is stable without clamping stagnation; Rigid transmission chain makes mast bearing power increase, can place heavier equipment, and mast is supported by rigid transmission chain and there will not be displacement and downslide; The back segment of driving chain can be wound into many storage layers, decrease and take up an area space, be convenient to transport; Move through motor and the PLC of rigid transmission chain control, and the adjustable height of mast can be made accurate, can range can optional position stop, improve the applicability of mast, may be used on the high equipment of military project equally accurate requirement.Such as in order to ensure disguise, equipment on mast is raised to when slightly exceeding treetop, electric up-down mast just can reach precision like this; The rigidity of electrodynamic type mast is better, not easily rocks, still can use in the presence of a harsh environment.
