Description

Bundling device

Technical Field

The invention relates to a bundling device for carding pull wires.

Background

The bundling device (or called wire bundling device) is used for circumferentially sequencing a plurality of pull wires so as to obtain a better tensile effect of the pull wires.

The binding device is generally used for sequencing a pull wire with a large length (or span), and the pull wire can be a pull wire for applying static force (a pull wire for hanging a heavy object) or a pull wire for applying dynamic force (a pull wire for lifting a heavy object).

As shown in fig. 1 and 2, a binding device 100 in the prior art generally includes a disk-shaped body 101, a plurality of open grooves 102 are formed on the periphery of the disk-shaped body 101, the plurality of grooves 102 are circumferentially arranged, a plurality of pull wires 200 are correspondingly located in the plurality of grooves 102 one by one, and both sides of the disk-shaped body 101 bind all the pull wires 200 together by means of a binding band, so that the pull wires 200 receive a radially inward component force, and the pull wires 200 are tightly attached to the bottom of the grooves 102 and are not easily separated from the grooves 102.

However, the above-mentioned bundling apparatus has the following disadvantages:

1. when the pulling force applied to the pulling wire fluctuates greatly, the pulling wire in the groove may be pulled out of the groove, for example, when a heavy object hung by the pulling wire is suddenly separated from the pulling wire, the pulling wire may have a large resilient force, which may cause a large radially outward resilient component of the pulling wire near the disk-shaped body, which may cause the pulling wire to be pulled out of the groove.

2. At the moment that the weight is lifted by the stay wire, the radially inward component force of the stay wire near the disc-shaped body is suddenly increased, so that large impact is generated between the stay wire and the disc-shaped body, and if the impact frequently occurs, the stay wire can be broken at the position of the disc-shaped body.

As shown in fig. 3 to 6, the disclosed embodiment of the present invention discloses a braiding apparatus, including: a wire harness body 10 and a hoop 20.

The harness body 10 includes: a ring-shaped body 11 and a support mechanism 12. The annular main body 11 is made of a steel plate and has a certain thickness, the ratio of the outer diameter to the thickness of the annular main body 11 is approximately 4:1, a plurality of insertion holes 111 penetrating in the radial direction are formed in the annular main body 11, and the insertion holes 111 are uniformly distributed in the circumferential direction.

The supporting mechanism 12 includes a plurality of supporting mechanisms 12, the plurality of supporting mechanisms 12 correspond to the insertion holes 111 one by one, and the plurality of supporting mechanisms 12 are arranged along the circumferential direction of the ring main body 11. Each support mechanism 12 includes: bushing 124, support post 122, spring 123, stop nut 125, first lock nut 126, second lock nut 127, and bearing block 121.

The top thread 1242 penetrates the stop plate 1241 and is screwed below the boss surface, so that the bushing 124 can be prevented from rotating.

The bushing 124 is made of nylon material, which does not cause difficulty in disassembly due to rusting of the ring-shaped body 11.

The inner bore of the bushing 124 is configured as an oblate cross-section inner bore through which the inner end of the support post 122 passes, the support post 122 also being oblate in cross-section so that the support post 122 mates with the inner bore of the bushing 124 so that the support post 122 does not rotate relative to the bushing 124.

A stud is formed at the outer end of the supporting column 122, the inner end of the bearing block 121 is in threaded connection with the stud, a second locking nut 127 is further sleeved on the stud, and the bearing block 121 is detachably fixed at the outer end of the supporting column 122 by screwing the second locking nut 127.

Each pulling wire 200 is elastically supported by the supporting mechanism 12, and when the pulling force applied to the pulling wire 200 increases suddenly, the impact of the pulling wire 200 on the wire-binding body 10 is buffered by the supporting mechanism 12 through retraction, thereby effectively reducing the probability of breakage of the pulling wire 200 near the U-shaped groove 1211.

3. When the pulling force applied to the pulling wire 200 suddenly increases, the radial dimension of the wire harness body 10 is elastically reduced due to the retraction of the supporting mechanisms 12, the elastic reduction of the radial dimension of the wire harness body 10 is converted into the increase of the overall length of the pulling wire 200, that is, all the pulling wires 200 as a whole generate elastic stretching in the length direction, and the stretching of the pulling wire 200 in the length direction can effectively buffer the impact of the sudden increase of the pulling force on any position of the pulling wire 200 in the length direction.
