Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Guide rail (1) is the annular of semi arch for the cross section is ［ ］ shape two ends, two guide rails (1) shape, equal and opposite in direction, and orthogonal, symmetrical, level is installed in the same plane, and two guide rails (1) intersection has four crossings, guide rail (1) to be fixed on the base plate (14) with support column.

Be fixed with the driving and driven sprocket wheel (16) of two groups of symmetries, vertical, uniform being fixed on the base plate (14) of four sprocket shafts (10) of (17) respectively.Two chains (2) are engaged on respectively on the cylindrical of driving and driven sprocket wheel (16) that two groups of horizontal directions install, (17), two chains (2) are parallel with guide rail (1) under guide rail (1), but not in same plane, intersect vertically mutually, the axle center of driving and driven sprocket wheel (16), (17) and guide rail (1) two ends center of arc constitute transmission mechanism on same axis.

The top of datum axle (20) is equipped with bearing holder (housing, cover) (21), the outer dead turn (22) of encircling of bearing holder (housing, cover) (21), the rope strand dish (18) that has rope strand (19) is installed on the base (23), base (23) can rotate around datum axle (20), datum axle (20) is fixed on the connecting rod (28) with nut, and end is welded on-the last or middle last formation of push-rod frame (3) rotating device that blind hole is arranged of ┬ ┬ shape two bent angle cylinders of fixed mount (9) of ┐ shape.

Wheel (26) is installed at wheel shaft (27) two ends, and welding fixedly is equipped with the horizontal beam (25) that turns to guide wheel (24) in two ends, and connecting rod (28) is linked to be former and later two wheel shafts (27) on the wheel of integral body.

Below lower floor's chain (2), the base plate (14) of four crossings of two guide rails (1) is gone up two guide plates (12) that the guide channel (11) of upper and lower two symmetries is arranged on the welding inner surface.

Ram seat (7) is fixed on the lower end of lower chain (2), the end of the columniform forward and backward push rod of long and short difference (5), (6) is equipped with propelling sheave (13), forward and backward push rod (5), (6) are enclosed within respectively on two ram seat (7), passing lower floor's chain (2) from bottom to top inserts in two blind holes of push-rod frame (3) lower end, terminal propelling sheave (13) contacts with ring rail (15) on the base plate (14) respectively, and guide plate (12) constitutes crossover device together.

Rotating device, wheel, crossover device constitute dolly (4), wheel, rotating device constitute dolly (8), 4 dollies (8) utilize direct uniform being fixed on the chain (2) of cylinder on the fixed mount (9), and 4 dollies (4) utilize that ram seat (7) is uniform to be fixed on the lower chain (2).Be connected with motor with two driving chains respectively on lower floor's chain drum of the drive sprocket (16) in two groups of driving and driven sprocket wheels (16), (17), constitute power source.

Take-up is made of fixed pulley group (29) of suspending in midair and the cheese (31) that is placed on ground.

During use, starting power switch, driven by motor driving chain makes connected two drive sprockets (16) with identical speed, opposite direction rotation, respectively be with a chain (2) to do suitable, motion counterclockwise, suitable, rotation counterclockwise also is being with chain (2) in eight dollies (4), (8) that are separately fixed on two chains (2).

When dolly (4) during through four crossings, cause is at upper and lower chain (2) infall, lower floor's chain (2) institute's band dolly (4) is walked and horizontal upper strata chain (2) when meeting in motion the place ahead, the propelling sheave (13) of preceding push rod (6) lower end enters and is rolled to the extreme lower position of the following guide channel (11) on two guide plates (12) from ring rail (15), at this moment deviate from the blind hole of preceding push rod (6) from push-rod frame (3), the top is lower than upper strata chain (2), the below in upper strata chain (2) just.Dolly (4) moves forward under the drive of rear push-rod (5), after treating that preceding push rod (6) is crossed upper strata chain (2), extreme lower position by the following guide channel (11) in the guide plate (12) rises to the extreme higher position immediately, and, its top is inserted in the blind hole on the push-rod frame (3) again with preceding push rod (6) jack-up upwards.At this moment rear push-rod (5) drops to the extreme lower position that goes up guide channel (11) again simultaneously, deviate from the blind hole from push-rod frame (3), avoid the last chain (2) that is about to collide, after treating that chain (2) is crossed in dolly (4) continuation reach, rear push-rod (5) is gone up at guide plate (12) under the effect of guide channel (11), upwards jack-up, the top is inserted again in the blind hole on the push-rod frame (3), continue again to travel forward counterclockwise, by that analogy, no longer describe in detail.

Be fixed on the no crossover device of 4 dollies (8) on the chain (2), directly under the drive of chain (2), move clockwise, dolly (4), (8) rotate a circle (revolution) along guide rail (1), and himself is also along datum axle (20) rotate a circle (rotation).

Dolly (4), (8) that rope strand (19) and rope strand dish (18) are housed are at the uniform velocity mobile in guide rail (1), pass through intersection mutually one by one, rope strand (19) constantly is pulled out rope strand dish (18), it is clockwise to knit out half rope strand, 8 anti-steel wire ropes (30) of turning round that half rope strand is counterclockwise, by certain assembly pulley (29), hub disk is gone into by in electronic power-actuated cheese (31).

The utility model is compared with prior art: because adopting the transmission mechanism of chain and sprocket engagement, its simple in structure, easy manufacturing, cost are low, and crossover device is equipped with in the lower end of dolly in the operating mechanism, make dolly all the time can be in guide rail continuously, automatically, at the uniform velocity mobile, knit out the anti-kernmantle of turning round, high efficiency makes 3～5 times of braiding Speed improvings.

Make the moving of car except bearing dolly weight because of dolly wheel again, also be equipped with 8 and turn to guide wheel and guiding cheekn to be close to forward and backward, especially at guide rail circular arc turning, can adjust the direction of motion of dolly, make that dolly remains steadily, state travels at the uniform speed, safe and reliable, thus knit out high-quality kernmantle.
