Description

A cable winding device for automatically retracting long rubber hoses or cables

technical field

The utility model relates to a cable winding device, in particular to a cable winding device for automatically retracting long rubber hoses or cables, which is suitable for large-scale engineering equipment fields such as related measuring equipment that automatically retracts long rubber hoses and thick cables.

Background technique

At present, many actuators or measuring devices that need to be stretched out for a long length during construction and retracted at the end of construction generally use the energy storage principle of coil springs. When the cable is pulled out by external force, the coil spring in the wire box is gradually compressed and accumulates elastic energy during the compression process. The principle of retracting rubber hose or thick cable is very simple, but the manufacturing cost of a large coil spring is very high. A common size rubber hose reel costs tens of thousands of yuan, and the larger the coil spring is, the more difficult the manufacturing process is, and the longer the service life is. In short, there is no product available for batch application in China.

Utility model content

The technical problem to be solved by the utility model is to provide an automatic cable winding device with relatively low manufacturing cost and simple process in view of the shortcomings of the above-mentioned prior art, and has a wide adaptability to the length of the cable winding.

The technical solution adopted by the utility model is: a cable winding device for automatically retracting a long rubber hose or cable, which is characterized in that it includes a frame, a piece to be wound, a reel body, a first gear, a second gear, a spring seat, The compression spring and the rack, the second gear and the reel body can be rotatably arranged on the frame, the first gear is meshed with the second gear, the first gear is fixed on one side of the reel body and the two Coaxial, the spring seat is fixed on the frame, there is a cavity in the spring seat, one end of the compression spring is fixed in the cavity, one end of the rack extends into the spring seat to connect with the compression spring, and the other end extends out of the spring The seat is engaged with the second gear, and the compression spring and the rack are arranged horizontally.

Further preferably, the top of the reel body is provided with a crimping guide post, the crimping guide post is fixed on the frame, the crimping guide post is hollow, and the part to be wound is wound through the crimping guide post. in the reel body.

Further preferably, the number of teeth of the first gear is smaller than the number of teeth of the second gear.

Further preferably, protrusions are provided on both sides of the connecting end of the rack and the compression spring.

The utility model is easy to manufacture and low in cost. It converts the rotation of the reel body into a linear displacement. The transmission ratio of the gear can be designed according to the length of the rewinding parts that need to be retracted, such as the length of the rubber hose or cable and the compression stroke of the spring. Different transmission Compared with corresponding to different hose or cable lengths, the adaptability to the coiled cable length is wide.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1 and Figure 2, a cable winding device for automatically retracting a long rubber hose or cable includes a frame 7, a part to be wound 1, a reel body 3, a first gear 4, a second gear 9, and a spring seat 5, compression spring 6 and rack 8. The second gear 9 and the reel body 3 are rotatably arranged on the frame 7 , the first gear 4 meshes with the second gear 9 , and the number of teeth of the first gear 4 is smaller than that of the second gear 9 . The first gear 4 is fixed on one side of the reel body 3 and the two are coaxial. The spring seat 5 is fixed on the frame 7. A cavity is provided in the spring seat 5. One end of the compression spring 6 is fixed in the cavity. One end extends into the spring seat 5 and connects with the compression spring 6 , the other end extends out of the spring seat 5 and meshes with the second gear 9 , the compression spring 6 and the rack 8 are arranged horizontally. In order to prevent the rack 8 from coming out of the spring seat 5 , protrusions 10 are provided on both sides of the connecting end between the rack 8 and the compression spring 6 .

In particular, the top of the reel body 3 of the utility model is provided with a thread-pressing guide post 2, which is fixed on the frame 7, and the interior of the thread-pressing guide post 2 is hollow, and the winding part 1 passes through it. The crimping guide post 2 is wound on the drum body 3 . The setting of the crimping guide post 2 can make the to-be-wound piece 1 not deviate when it is retracted and pulled out.

Implementation column 1

The power storage principle of the utility model is shown in Figure 1. When the unwinding piece 1 is pulled out, the unwinding piece 1 is a rubber hose or cable, and the unwinding piece 1 passes through the pressing line guide post 2 to drive the reel body. 3 rotates, the first gear 4 fixedly connected with the reel body 3 also rotates in the same direction, and drives the second gear 9 meshed with the first gear 4 to rotate clockwise. The second gear 9 drives the rack 8 meshed with it to move in a straight line to the left. The left end surface of the rack 8 will give a continuous pressure to the compression spring 6 to convert the tension of the hose or cable into the elastic force of the compression spring 6 and store it in the In the spring chamber, when the to-be-winding machine stops stretching out, the pulling force exerted on the to-be-winding piece 1 is balanced with the elastic force of the spring.

Implementation column 2

The principle of the utility model is shown in Figure 2. When the pulled-out part 1 is completed and starts to retract, the part 1 is a rubber hose or a cable, and the pulling force applied to the rubber hose or cable Gradually decrease, the rubber hose or cable that has been pulled out will be pushed by the stored spring force to move the rack 8 to the right in a straight line and at the same time drive the second gear 9 to rotate counterclockwise, the second gear 9 transmits the power to the first gear 4 , so the first gear 4 drives the reel body 3 fixedly connected with it to rotate clockwise, and the rubber hose or cable pulled out is gradually retracted and wound on the reel body 3 after passing through the crimping guide post 2 .

The above description only expresses the preferred implementation of the present utility model, and its description is relatively specific and detailed, but it should not be understood as limiting the patent scope of the present utility model. It should be pointed out that those skilled in the art can make several modifications, improvements and substitutions without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
