Abstract
The invention discloses a novel movable support type heavy-duty drag chain, relates to a novel movable support type heavy-duty drag chain which has the functions of centralized supporting, reciprocating movement traction and protection for various conveying pipes and cables of electric energy, hydraulic pressure, pneumatic power, liquid raw materials and the like of metallurgical steel rolling equipment, large-sized mechanical equipment and large-sized automatic production lines in continuous operation. The drag chain is characterized in that: one surface of a drag chain body consists of a group of powerful torsion springs and the other surface of the drag chain body consists of a plurality of freely adjustable chain rails to replace a thick and heavy chain plate which is formed by stamping and welding two layers of steel plates in the prior art; and a pipe/ cable supporting bridge plate and a partition plate which are integrated with each other are used for replacing a supporting plate in the prior art. A manufacturing process can be performed without a series of stamping and carrying moulds and equipment with high cost. The key point of the invention is that: the drag chain can be bent and moved by elastic deformation of the torsion springs, and reverse acting force of the torsion springs is skillfully utilized to obviously relieve load and wear on a connection part of the drag chain. The drag chain is also characterized in that: the freely adjustable chain rails of the drag chain body and a roller or roller assembly which has the same bending radius as the drag chain and is provided with a tooth socket are adopted to movably support the drag chain to operate with heavy duty. The drag chain solves the problems of heaviness and unreasonable supporting of the heavy-duty drag chain in the prior art, and overcomes the disadvantages of quick wearing of a heavy-duty drag chain plate hole and a pin shaft in the prior art.
Description
Technical field
The present invention relates to move back and forth the concentrated carrying of multiple delivery pipe cables such as the electric energy, hydraulic pressure of metallurgy, shipbuilding, heavy mechanical equipment and the large-scale automatic production line of operation, pneumatic and liquid charging stock, move back and forth the novel mobile support formula heavy duty drag chain of traction and protection purposes.
Background technique
The heavily loaded drag chain of the prior art structurally carrier bar of both sides is welded with double-deck punching press steel plate after by plate stamping again, because the bearing capacity that is restricted to the heavily loaded drag chain of assurance of support mechanism and free unsettled ability, rigidity and intensity that assurance is enough are often done other part of carrier bar of drag chain solid thick and heavy, whole drag chain is very heavy after loading onto extensive work pipe cable in use, and (see shown in Figure 13 background technique photo data: 13.1 are depicted as the situation photo that the carrier bar bearing pin begins to wear and tear because chain plate hole and the very little wearing and tearing of carrier bar bearing pin surface of contact are very fast; 13.2 be depicted as the situation photo that the carrier bar bearing pin enters wear stage; 13.3 be depicted as the situation photo of carrier bar bearing pin heavy wear), cause the carrier bar connection part loosening, drag chain is constantly downwarp under the heavy load effect, working resistance also constantly increases, wearing and tearing and vibration aggravation, usability descends, life-span comprises that also shorten relatively the working life of built-in delivery pipe cable, and because heavily loaded drag chain market consumption is less relatively, generally be not very big in batches in the production process, but the operator still need be higher relatively according to requirement the configuration a large amount of expensive blanking die and the punching equipment cost of production maintenance costs of seriation.
In addition because the heavily loaded drag chain of prior art does not have when working under the supporting situation because of the very fast disappearance of the free unsettled ability of drag chain at the first half stroke because of support mechanism is unreasonable, self contacts drag chain up and down, directly friction drags mutually, cause resistance to increase, wearing and tearing are accelerated, (see shown in the last figure of Figure 12 background technique photo data: 12.1 be depicted as after the serious downwarp of heavily loaded drag chain before half trip working state photo; 12.2 be depicted as half trip working state photo in back after the serious downwarp of heavily loaded drag chain).Too little because of drag chain generation downwarp, fixed bearing roller diameter on the half stroke of fixed supported back, drag chain forms cornerite on the trundle both sides, moving resistance is increased, and vibration and noise increase, and fault also increases (seeing shown in Figure 12 background technique photo data figure below) thereupon
Summary of the invention
It is lighter to the purpose of this invention is to provide a kind of weight, and carrying can increase, and increase working life, and manufacture process can not used blanking die and punching equipment, and cost of production is lower, the novel mobile support formula heavy duty drag chain of function admirable.
The one side of drag chain body of the present invention is connected with integrated pipe cable carrying bridge plate respectively by connecting bearing pin by free adjustment chain rail by one group of torsion spring another side, form the very strong elasticity drag chain body of elasticity, during the crooked mobile working of drag chain, inner chamber is supported by free adjustment chain rail and the reverse elastic force by torsion spring significantly alleviates the pipe cable and can not disappear to the load of free adjustment chain rail and the wearing and tearing of connection part and the elasticity of torsion spring.
The present invention adopts the roller that moves in pairs (or by some to forming supporting structure by tooth and anodontia roller) the supporting drag chain is omnidistance and moves, the rolling garden radius of roller equals or is slightly larger than the drag chain bending radius, the garden perimeter surface of roller is shaped on groove and embeds the solid cushion rubber of a certain size and width and be higher than the roller surface certain altitude so as to vibration damping with abate the noise, there is the gear ring joint garden tooth pitch of tooth roller to equate with integrated pipe cable carrying bridge plate adjacent segments distance, to guarantee that drag chain is meshed with the roller gear teeth in moving, mobile support structure and drag chain body are not disturbed, simultaneously because of adopting the mobile support mode.The pitch of novel mobile support load-carrying drag chain free adjustment chain rail can suitably increase than the carrier bar pitch of prior art.

Embodiment
With reference to Fig. 1 one Figure 11, to manage both sides and two kinds of torsion springs 2 and 3 on cable carrying bridge plate 5 one side and couple together simultaneously with connecting bearing pin 11, carrying bridge plate 5 another side both sides are connected with free adjustment chain rail 4, be in turn connected into the elasticity drag chain body of certain-length, by implementing Front view 1 supporting rollern 7 and 8 is determined that according to the width dimensions of the whole drag chain in assembling back and drag chain total travel length and loading condition the logarithm of supporting rollern 7 and 8 forms on the free adjustment chain rail 4 that whole support mechanism places drag chain then, should satisfy the effect of rolling bearing nimbly and freely, come to make its free adjustment chain rail pressure on supporting rollern 7 and 8 and with haulage gear, to link up the bending of the elasticity drag chain body the other end again, can reach the purpose of novel load-carrying drag chain mobile support.To manage cable demarcation strip 6 then and be installed on the integral tube cable carrying bridge plate 5, solid cushion rubber 9 is contained in respectively in the groove of roller 7 and 8 wheel faces, and cushion rubber 9 outer gardens exceed the wheel face certain altitude, vibration damping and the effect that abates the noise when reaching drag chain work.
