As shown in fig. 1 to 3, the chain winding device of the present embodiment includes: the device comprises a fixed part 10, a rolling chain piece 20, a drag chain 30 and a restraint piece 41, wherein the rolling chain piece 20 and the fixed part 10 are arranged at intervals and are provided with hollow through holes, and the hollow through holes are suitable for being fixedly connected with the outer peripheral surface of a rotary table 50; the first end of the drag chain 30 is fixed on the fixed part 10 and the second end is fixed on the rolling chain piece 20, and a bent section is arranged between the first end and the second end of the drag chain 30; the restraint 41 is provided on the fixing member 10 and cooperates with a portion of the drag chain 30 between the bent section and the second end to restrain a degree of bending of a portion of the drag chain 30 connected to the bent section.

With the zipper rolling device of the present embodiment, the hollow through hole of the zipper element 20 is fixed on the outer circumferential surface of the turntable 50, the cable and the signal line are fixed in the drag chain 30, and when the turntable 50 rotates clockwise, the drag chain 30 is wound on the zipper element 20; when the turntable 50 rotates counterclockwise, the zipper member 20 releases the drag chain 30, and the drag chain 30 is collected to the fixed member 10. The chain rolling piece connected with the drag chain of the chain rolling device is a rotary moving body, a cable and a signal wire can be led into electric equipment (shown in the figure) on the rotary table, and the chain rolling piece is fixed on the outer peripheral surface of the rotary table, so that the installation of the equipment on the table surface of the rotary table cannot be influenced, and the problem that the conductive slip ring is difficult to install on a large rotary table is effectively solved. In the moving process of the drag chain 30, the restraint piece 41 is matched with the part, located between the bent section and the second end, of the drag chain 30, the restraint piece 41 exerts restraint force towards the drag chain 30, the part, connected with the bent section, of the drag chain 30 is prevented from being bent too much, the normal work of cables and signal wires is guaranteed, and the situation that the cables and the signal wires are damaged due to the fact that the drag chain is bent too much when the drag chain is loosened is prevented.

In the prior art, a part connected with a drag chain is a linear moving body, the drag chain is placed in a vertical mode, the drag chain is placed on a flat plate, the drag chain is supported by the flat plate, and the drag chain is driven to move back and forth on the flat plate when the linear moving body moves back and forth. The drag chain of the embodiment is placed in a horizontal mode, if the restraint piece 41 is not arranged, when the drag chain 30 is loosened, the drag chain 30 can be arched and bent, when the bending angle of the drag chain 30 is too large, cables and signal wires in the drag chain can be damaged, and through the arrangement of the restraint piece 41, when the drag chain is loosened, the restraint piece 41 exerts restraint force on the drag chain, so that the situation that the cables are damaged due to the fact that the drag chain is arched and bent is prevented.

In the present embodiment, as shown in fig. 6 to 9, the winding chain member 20 is a winding sprocket, and the cross-sectional shape of the winding surface of the winding sprocket is an archimedes spiral. When the turntable 50 rotates to reach and exceed 360 degrees, the chain rolling member in the shape of an archimedes spiral allows the drag chain 30 to be smoothly rolled, and avoids the situation that the drag chain 30 is impacted in the radial direction due to the 'jump' of the rolling radius of the drag chain. The expression of an archimedean spiral is a + B θ, where a is the minimum radius value (Rmin), B = H/360 °, H is the outer tow chain height, e.g., Rmin =504, outer tow chain height H =50, then R =504+ (50/360) θ. Since the "curl radius" of the roll chain member 20 varies, the restraining force exerted on the tow chain 30 must be "flexible", i.e. the restraining force exerted with the stretching and rolling movements of the tow chain 30 "floats" in the horizontal plane, i.e. the restraining member 41 is movably arranged and abuts on the part of the tow chain 30 between the curved section and the second end.

In the present embodiment, the winding wheel includes two annular plates 21 disposed opposite to each other, a cylindrical body 22 disposed between the two annular plates 21, and an arc-shaped plate 23 disposed on the cylindrical body 22, and a portion of the circumferential surface of the cylindrical body 22 and the arc-shaped surface of the arc-shaped plate 23 form a winding surface. The winding chain wheel has simple structure, convenient processing and manufacturing and reduced cost. An outlet hole 211 is arranged on the upper annular plate 21, and cables and signal wires in the drag chain are led out from the outlet hole 211 to be connected with electrical equipment on the rotary table. The rolling chain wheel is fixed on the cylindrical surface of the turntable through a screw.

In this embodiment, the winding wheel further comprises a connecting plate 24 connected between the arc plate 23 and the cylinder 22, and the first end of the drag chain 30 is fixed on the connecting plate 24. The connecting plate 24 is convenient for fixing the drag chain 30 and is simple and convenient to connect. As an alternative embodiment, no connecting plate is provided, and the drag chain is fixed on the cylinder. The web 24 extends radially of the barrel.

In the present embodiment, as shown in fig. 2 to 5, the chain winding device further includes a lever 42 and an elastic member 43, a portion between both ends of the lever 42 is rotatably provided on the fixing member 10, the restraining member 41 is installed on one end of the lever 42, one end of the elastic member 43 is connected to the other end of the lever 42, and the other end of the elastic member 43 is fixed on the fixing member 10. The lever 42 is pushed to rotate by the elastic member 43, so that the constraining member 41 exerts a constraining force on the drag chain 30. The restraining element 41 is movably arranged through the lever 42 and the elastic element 43, and the device has the advantages of simple structure, convenience in use and low cost.

In this embodiment, the lever 42 includes a long arm 421 and a short arm 422 connected at an included angle, the connection part of the long arm 421 and the short arm 422 is rotatably disposed on the fixing member 10, the constraining member 41 is mounted on the end part of the long arm 421, and one end of the elastic member 43 is connected with the end part of the short arm 422.

In this embodiment, if a conventional coil spring or torsion spring is used as the elastic member 43, the elastic member 43 is selected from a nitrogen spring because the required restraining force is large and the physical size is large, and the nitrogen spring has a small volume and a large output force. For example, the overall dimensions of the nitrogen spring are phi 19 in diameter, 65mm in length, 10mm in stroke, 800N to 1300N in output, and the restraint force applied to the drag chain 30 is: 60N-150N.

In this embodiment, the fixing component 10 includes a bracket 11 and a fixing seat 12 fixed on the bracket 11, the tow chain 30 is fixed on the bracket 11, the lever 42 is rotatably disposed on the fixing seat 12, and the other end of the elastic member 43 is fixed on the fixing seat 12. The fixing part is divided into two parts, so that the processing and the manufacturing are convenient, and the processing difficulty is reduced.

In this embodiment, as shown in fig. 1 and fig. 2, the bracket 11 includes a bottom plate 111, a first vertical plate 112 and a second vertical plate 113, the first vertical plate 112 and the second vertical plate 113 are oppositely disposed on the bottom plate 111, the first end of the drag chain 30 is fixed on the first vertical plate 112, and the fixing base 12 is fixed on the second vertical plate 113. The first vertical plate 112 and the second vertical plate 113 play a role of guiding.

In this embodiment, the second vertical plate 113 is provided with an escape opening for escaping from the restraint 41, and the escape opening can escape from the restraint 41.

In this embodiment, as shown in fig. 2 and 3, the restraining element 41 is a pressing wheel rotatably disposed at one end of the lever 42, and the pressing wheel rotates to reduce the frictional resistance of the stretching movement of the tow chain when the tow chain moves.

In this embodiment, fixing base 12 has the spring holder, and nitrogen spring's the other end is fixed on the spring holder, wears to be equipped with jackscrew 45 on the short arm 422, and nitrogen spring's one end top is on jackscrew 45, adjusts jackscrew 45 and just can conveniently adjust nitrogen spring's initial force, and the structure is exquisite, simply adjusts initial force. The fixed seat 12 is provided with a rotating shaft, the lever is arranged on the rotating shaft, the lever is provided with a pinch roller shaft 44, and the pinch roller is arranged on the pinch roller shaft 44. Under the urging of the nitrogen spring, lever 42 rotates about the pivot axis, causing the pinch rollers to apply a restraining force to drag chain 30. When the drag chain stretches, the press wheel rotates around the press wheel shaft to reduce the friction resistance of the stretching motion of the drag chain. Because the lever can rotate around the rotating shaft, the pressing wheel is always pressed on the drag chain when the distance of the drag chain relative to the first vertical plate changes.

As shown in FIG. 1, the coiled part of the drag chain 30 is wound by a coil sprocket, the non-coiled part of the drag chain 30 is supported by the bracket 11, the bracket 11 is provided with a first vertical plate 112, and the static end of the drag chain 30 is fixed on the first vertical plate 112. When the rotary table 50 rotates counterclockwise, the drag chain 30 stretches leftwards and is folded on the first vertical plate 112 of the bracket 11; when the turntable 50 rotates clockwise, the drag chain 30 is wound by the winding sprocket on the turntable 50, and the drag chain 30 is wound to the right. When the drag chain 30 moves linearly to the left, a constraint force pointing to the first vertical plate 112 must be applied to the drag chain, and the constraint force is formed by a nitrogen spring-pressure wheel assembly composed of a lever, a pressure wheel and a nitrogen spring. Since the "curl radius" of the chain member 20 varies, which results in the distance of the straight portion of the extension movement of the tow chain 30 relative to the first upright plate 112 not being a constant value, the restraining force applied to the tow chain 30 must be "flexible", i.e., the restraining force applied as the tow chain 30 extends and contracts "floats" in a horizontal plane.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:

1. the drag chain is horizontally placed and wound on the chain rolling piece, and the chain rolling piece is fixed on the outer peripheral surface of the rotary table, so that the feeding of multiple cables and signal wires of the electrical equipment moving on the large-scale rotating equipment is realized.

2. The nitrogen spring pinch roller assembly applies constraint force to the stretching part of the drag chain, so that the condition that the cable and the signal wire are damaged due to overlarge drag chain bending when the drag chain is loosened is prevented.

3. The winding surface of the drag chain formed by the Archimedes spiral enables the drag chain to be wound more than 360 degrees stably.

4. The chain winding device realizes the feeding of multi-path electrical signals of electrical equipment when a large-capacity cable drag chain is applied to a large turntable, solves the design engineering difficulty of multi-path signal feeding when a conductive slip ring is applied to the large turntable, has higher reliability than the conductive slip ring, is convenient to maintain, and has low requirement on the operation skill of an operator.
