Technical Field

The invention relates to the field of cables, in particular to an wire and cable paying-off structure convenient to use.

Background

With the rapid development of the Chinese electronic technology, the scales of the industries such as the computer industry, the communication industry, the military industry, the aerospace industry, the ship manufacturing industry and the like are continuously enlarged, the requirements on wires and cables are rapidly increased, and the wire and cable industry has huge development potential in the future.

The existing electric wire and cable products have thousands of product varieties and specifications, but the traditional pay-off rack is not suitable for paying off of thin cables and has a complex structure, a large amount of time can be consumed during paying off, and manpower and material resources are consumed.

Disclosure of Invention

The invention aims to solve the technical problems that the existing pay-off machine is not suitable for paying off thin cables, is complex in structure, consumes more manpower and material resources and is low in use efficiency, and aims to provide wire and cable pay-off structures which are convenient to use and solve the use problem of the pay-off machine.

The invention is realized by the following technical scheme:

the kinds of electric wire and cable pay-off structures convenient to use comprise a rack, wherein a pay-off mechanism comprising a pay-off reel is arranged on the rack, and a tension control mechanism and a tension braking mechanism are also arranged on the rack;

the tension braking mechanism comprises a th connecting rod which is horizontally arranged, two ends of the th connecting rod are separately connected with a vertical second connecting rod and a pulley block, the lower end of the second connecting rod is connected with a braking mechanism for controlling the rotation of the pay-off reel, the upper end of the th connecting rod is provided with a driving device, and a cable is wound in the pay-off reel and is paid out through the pulley block and the driving device;

when the cable is pulled during paying off, the driving device presses the th connecting rod downwards, the th connecting rod drives the second connecting rod to move downwards, the brake mechanism below the second connecting rod is separated from the pay-off reel, and the pay-off reel rotates to pay off;

the tension control mechanism comprises a steel wire connected with the end and the driving device, and the other end of the steel wire is connected with a steel wire spring;

when stopping unwrapping wire, steel wire spring drives steel wire, drive arrangement and th connecting rod and gets back to original position, and the second connecting rod upward movement, brake mechanism are connected with the drawing drum, and the drawing drum stops rotatoryly.

, when the device is used and paying off is needed, a cable connected to the end of a driving device is pulled, the cable drives the driving device to press a th connecting rod under the action of pulling force, the th connecting rod moves downwards and further drives a vertical second connecting rod to move downwards, in the moving process, a brake mechanism is separated from a pay-off reel, the pay-off reel can rotate under the action of external force, paying off is conducted, when paying off is not needed, pulling on the cable is released, under the action of restoring force of a steel wire spring, the steel wire spring drives a steel wire to move to an original position, in the moving process, the steel wire drives the driving device to move, the driving device returns to the original position, the driving device does not bring pressure to a th connecting rod, therefore, the th connecting rod restores to the original position under the action of no pressure, in the restoring process, the second connecting rod moves upwards, further, the brake mechanism at the lower end of the second connecting rod is connected with the pay-off reel, the pay-off.

For the device, during operation, only pulling forces need to be provided at the ends of the outgoing lines of the cables to enable the cables to be outgoing, when the outgoing lines are not needed, the pulling forces on the cables are stopped, and the cables can be automatically stopped to rotate under the driving of the steel wire springs to stop the outgoing lines, so that the device is convenient to operate, simple in structure and convenient to use.

, the driving device comprises a driven poking wheel arranged on the connecting rod and a poking wheel positioned at the upper end of the driven impeller, the poking wheel is connected with a pay-off pulley through a connecting rod, and the cable is wound in the pay-off reel and is paid off through the pulley block and the pay-off pulley;

when the wire is paid off, the poking wheel rotates to press the driven poking wheel, and the movable poking wheel drives the th connecting rod and the second connecting rod to move downwards.

The drive arrangement of this structure adopts passive thumb wheel and thumb wheel interact, and during the pristine condition, passive thumb wheel and thumb wheel contact each other, and when the cable was dragged, the cable was through being used in on the unwrapping wire pulley, made the unwrapping wire pulley remove, and then unwrapping wire pulley china connecting rod makes undulant wheel carry out clockwise's rotation, and at rotatory in-process, the passive thumb wheel of thumb wheel pair provided decurrent power, and then made connecting rod drive second connecting rod downstream, used.

This structure adopts passive thumb wheel and thumb wheel interact, and both simple structure to do not need extra drive power to drive, under the diameter of passive impeller is less than the diameter of thumb wheel, the rotatory in-process of thumb wheel can produce decurrent power to passive thumb wheel, satisfies the user demand.

Therefore, for the structure of the device, not only the driving structure is simplified by steps, but also the cost is effectively saved, the paying-off can be rapidly carried out and stopped, and the use efficiency is improved by steps.

Specifically, brake mechanism includes brake block and brake wheel, and brake wheel and the coaxial fixed connection of drawing drum, when the second connecting rod moves down, brake block and brake wheel separation, drawing drum drive brake wheel rotatory, and when connecting rod primary position, brake block and brake wheel are connected, stop the unwrapping wire.

In the process that the second connecting rod moves downwards, the brake block on the second connecting rod is driven to move downwards and is separated from a brake wheel connected with the axis of the pay-off reel, and then the pay-off reel can rotate for pay-off.

When the second connecting rod moves upwards, the brake block on the second connecting rod is driven to move upwards and is in contact with a brake wheel connected with the axis of the pay-off reel, the brake block is connected with the brake wheel, the brake block enables the brake wheel to stop rotating, and then the pay-off reel stops rotating and paying off.

Preferably, in the original position, the included angle between the connecting rod and the th connecting rod is 30 degrees, in the original position, the connecting rod is obliquely and obliquely arranged upwards, and the connecting rod rotates clockwise towards the large included angle between the connecting rod and the th connecting rod, so that the arrangement is more beneficial to providing downward force for the driven thumb wheel effectively in the clockwise rotation process of the thumb wheel, and the use is more convenient.

Moreover, the pulley block of the device comprises two single-shaft double pulley blocks arranged side by side. The pulley block for hoisting adopts a single-shaft double-pulley block technology, the steel wire rope in the pulley is not easy to drop out of the groove, and the service efficiency is higher.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. the kinds of wire and cable paying-off structures convenient to use are simple in structure, free of complex structures, safe, reliable, reasonable in structural principle design, convenient to operate, interchangeable and good in economic benefit;

2. the convenient electric wire and cable paying-off structures are simple in structure, convenient and practical, and manual paying-off can be greatly reduced;

3. according to the wire and cable paying-off structure convenient to use, the brake is controlled by tension, heavy-load and various thick and thin wire and cables can be easily paid-off, all cables can be paid-off on a tension paying-off machine, and the using efficiency is higher.
