Description

Cable winding and unwinding devices

Technical Field

The utility model relates to a receive, put cable so that cable length adaptation user equipment's device.

Background

The cable is a general name of a long-line article such as an optical cable and an electric cable, and can also be a pipeline piece such as a water pipe, an air pipe, an oil pipe and the like which can be folded into a roll package and made of a flexible material. The cables mainly serve for connecting equipment or conveying water, electricity and gas, and the like, and have high importance and strict safety requirements. On the other hand, in many mechanical devices, in order to ensure the stability and flexibility of the working end during operation and the requirement of controlling the weight of the working end, the working end is not provided with a power system, but a power station is arranged at other places of the mechanical device, and the power station and the working end are connected through cables. But the position of the working process of the working end can be adjusted at variable times, and can even stretch out and draw back as required, under the condition, the cable also needs to be adjusted timely to ensure the orderliness of the cable and avoid influencing the operation of the equipment. The cable winch is a commonly used cable winding and unwinding device, but in order to smoothly recover cables, the cable winch is required to be powered or provided with a power device, so that energy consumption is increased, the environmental protection performance is reduced, and the economical efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a need not power and can adapt to the flexible cable winding and unwinding devices who needs of equipment to satisfy the cable and receive and release needs and reduce the energy consumption and improve economic performance.

The cable winding and unwinding device comprises a main arm and an operation arm moving relative to the main arm, wherein a winch for winding and unwinding a cable is mounted on the main arm, and the cable bypasses the winch to be connected with the operation arm; the rotating shaft of the winch is also provided with a gear, the operation arm is fixedly connected with a rack, and the setting direction of the rack is consistent with the moving direction of the operation arm and is meshed with the gear.

In the cable winding and unwinding device, one end of a cable is connected with a power system, the other end of the cable bypasses a winch and is connected with an operation arm, and the operation arm is connected with a rotating shaft of the winch through a rack and a gear; when the operation arm moves relative to the main arm, the rack is driven to synchronously move, and the rack drives the rotating shaft to rotate through the gear, so that the winch is driven to rotate to take in and pay out the cable; if the working arm extends out of the main arm, the winch pays out the cable to meet the position change of the working arm so as to ensure the connection of the cable; if the operation arm retracts from the outside to the main arm, the winch recovers the cable so as to ensure the tidiness of the cable and avoid influencing the operation of the equipment. The cable winding and unwinding device enables the winch to be matched with the moving of the operation arm under the action of the rack and pinion pair, is simple and ingenious in structure, easy to manufacture and convenient to popularize, does not need extra power supply, can effectively reduce energy consumption and improve economic performance, is quick and accurate to operate, and can effectively guarantee the accuracy of winding and unwinding of cables so as to guarantee the stability and safety of equipment operation.

Detailed Description

A cable pay-off and take-up device comprises a main arm 1 and an operation arm 2 moving relative to the main arm, wherein a winch 3 for paying off and taking up a cable is installed on the main arm, and a cable 4 bypasses the winch and is connected with the operation arm; the rotating shaft 5 of the winch is also provided with a gear 6, the operation arm is fixedly connected with a rack 7, and the arrangement direction of the rack is consistent with the moving direction of the operation arm and is meshed with the gear.

As shown in fig. 1-4, one end of the cable is connected with the power system, the other end of the cable is connected with the working arm after the middle section of the cable bypasses the winch, and the working arm is connected with the rotating shaft of the winch through a rack and a gear; when the operation arm moves relative to the main arm, the rack is driven to synchronously move, and the rack drives the rotating shaft to rotate through the gear, so that the winch is driven to rotate to take in and pay out the cable; if the working arm extends out of the main arm, the winch pays out the cable to meet the position change of the working arm so as to ensure the connection of the cable; if the operation arm retracts from the outside to the main arm, the winch recovers the cable so as to ensure the tidiness of the cable and avoid influencing the operation of the equipment. The cable winding and unwinding device enables the winch to be matched with the moving of the operation arm under the action of the rack and pinion pair, is simple and ingenious in structure, easy to manufacture and convenient to popularize, does not need extra power supply, can effectively reduce energy consumption and improve economic performance, is quick and accurate to operate, and can effectively guarantee the accuracy of winding and unwinding of cables so as to guarantee the stability and safety of equipment operation.

In the cable pay-off and take-up device, the working arm 2 is fixedly provided with the wiring terminal 8 for connecting the cable 4, and the wiring direction of the wiring terminal and the winch 3 is parallel to the moving direction of the working arm, so that the cable can be basically parallel to the moving direction of the working arm and the arrangement direction of the rack, the cable is prevented from influencing the working safety of other parts, and the cable is more tidy and convenient to pay off and take up.

In the cable winding and unwinding device, a guide mechanism for guiding the rack 7 is mounted on the main arm 1, and the guide mechanism can be a guide plate or a bracket provided with a guide groove, or can also comprise a plurality of guide wheels 9 arranged at the bottom of the rack 7 as shown in fig. 1-4; in addition, the one end of the back operation arm 2 on the rack 7 can be provided with a limiting block 10, the limiting block abuts against the guide mechanism or the winch 3 and limits the operation arm to extend outwards so as to avoid the rack and the gear from falling off, and the stroke limitation can be formed on the operation arm so as to avoid safety accidents caused by the fact that the operation arm exceeds the extension length.
