Description

Technical Field

[0001] This utility model relates to the field of cable winding safety technology, and in particular to a cable auxiliary winding component. Background Technology

[0002] After cables are no longer in use, they need to be rolled up for future use. Rolling up cables not only makes storage easier but also better protects them. When rolling up cables, the I-beams on the cable winding machine are rotated to wind the cables onto the I-beams.

[0003] The I-beams on most cable reels are driven by a power mechanism, commonly a motor or cylinder. Some reels are manually rotated using a hand crank. Regardless of the method, because cable reels or reels are inconvenient to carry, they are usually kept stationary, and the cable is dragged over from a distance during winding (piling the cables together beforehand is not only cumbersome but also prone to tangling).

[0004] While the cable is being pulled over from a distance, it may get stuck on the legs of some equipment or in gaps in the building, preventing it from moving. In this case, it is necessary to stop reeling in the cable immediately, otherwise the cable will become stretched and generate a large pulling force, which may easily damage the cable and the cable reeling machine itself.

[0005] However, the workers who are reeling in the cable may not be able to notice or react immediately, which may result in damage to the cable and the reeling machine itself, or even the reeling machine being pulled backward and falling over, posing a safety hazard to the workers.

[0006] Therefore, an auxiliary cable reel component needs to be designed to provide safety protection and prevent the aforementioned adverse situations from occurring. Utility Model Content

[0007] In view of this, the purpose of this utility model is to propose a cable auxiliary take-up assembly to solve the problem in the prior art where the cable gets stuck during take-up, resulting in a large pulling force that damages the cable and the take-up machine itself.

[0008] To achieve the above objectives, this utility model provides a cable auxiliary winding assembly, including a bracket fixedly connected to a base and an I-beam wheel rotatably connected to the bracket. The auxiliary winding assembly further includes:

[0009] A connecting shaft is fixedly connected to the inside of the bracket. The middle roller of the I-beam wheel is a tubular component with open ends. The connecting shaft is rotatably connected inside the middle roller, and a linkage mechanism is provided between the connecting shaft and the middle roller.

[0010] Furthermore, the linkage mechanism includes a ball that is movably connected to the outer surface of the connecting shaft, and the inner wall of the intermediate roller is also provided with a groove that cooperates with the ball.

[0011] The rollers are provided in a number of parts, and the inner wall of the middle roller is also provided with a number of slots that are the same number as the number of rollers and whose positions correspond to those of the rollers.

[0012] Furthermore, the ball bearings are provided in a plurality of form, and the inner wall of the intermediate roller is also provided with a plurality of slots that are the same number as the ball bearings and whose positions correspond to them.

[0013] Furthermore, the connecting shaft is provided with a ball groove inside, and the ball is movably connected in the ball groove.

[0014] Furthermore, a support plate is provided below the ball, and the support plate is slidably connected in the ball groove.

[0015] Furthermore, a spring is also provided in the ball groove, with the upper and lower ends of the spring connected to the bottom of the support plate and the inner end of the ball groove, respectively.

[0016] Furthermore, a power mechanism, which is a motor or a cylinder, is fixedly connected to the outer side of the bracket, and the connecting shaft is fixedly connected to the output shaft of the power mechanism.

[0017] Furthermore, the outer side of the bracket is also provided with a manual rocker arm, the inner end of which is inserted into the bracket and detachably connected to the connecting shaft.

[0018] The beneficial effects of this utility model are as follows: 1. The middle roller of the I-beam is set as a tubular component with open ends, and the transmission relationship between the connecting shaft and the I-beam is set as a rotary connection. This makes the connection between the I-beam and the connecting shaft no longer rigid. When subjected to greater resistance, the connecting shaft can rotate freely inside the I-beam, avoiding hard pulling and effectively protecting the cable and the take-up machine itself.

[0019] 2. A linkage mechanism is installed between the connecting shaft and the intermediate roller. During normal cable winding, the linkage mechanism keeps the connecting shaft and the intermediate roller relatively fixed, allowing the driving force of the drive mechanism to be transmitted to the I-beam, causing it to rotate and wind the cable. However, when subjected to significant resistance, the linkage mechanism loses its fixed connection function, allowing relative rotation between the connecting shaft and the I-beam.

[0020] 3. The linkage mechanism uses ball bearings and corresponding grooves. Additionally, the connecting shaft has internal ball bearing grooves, where the balls are movably connected. Springs hold the balls in place, allowing them to be locked within the grooves. When resistance is low, the balls remain locked in the grooves, enabling the connecting shaft to rotate the I-beam pulley. However, under greater resistance, the balls are forced into the ball bearing grooves and disengage from the grooves. At this point, the I-beam pulley and connecting shaft are no longer rigidly connected; the connecting shaft will spin freely inside the I-beam pulley, preventing the pulley from rotating and stopping the cable reel. This avoids excessive pulling force and provides a safety protection function. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] The first aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, since the take-up machine or reel is inconvenient to carry around, it is usually kept stationary while the cable is dragged over from a distance during the winding process. However, during this dragging process, the cable may get stuck on the legs of some equipment or in gaps in buildings, preventing it from moving. In this case, winding must be stopped immediately; otherwise, the cable will become stretched and generate significant pulling force, potentially damaging both the cable and the take-up machine itself. To address this, this embodiment rotatably connects the take-up reel 104 to the bracket 102, which is fixedly connected to the base 101. A connecting shaft 107 is fixedly connected to the inner side of the bracket 102.

[0032] The key point is that the intermediate roller 105 of the I-beam wheel 104 is a tubular component with open ends. The connecting shaft 107 is rotatably connected inside the intermediate roller 105, and a linkage mechanism is also provided between the connecting shaft 107 and the intermediate roller 105.

[0033] Therefore, the connection between the I-beam 104 and the connecting shaft 107 is no longer rigid. When subjected to greater resistance, the connecting shaft 107 can rotate freely inside the I-beam 104, avoiding hard pulling and effectively protecting the cable and the take-up machine itself.

[0034] The bracket 102 is also fixedly connected to a power mechanism 103, which is a motor or cylinder, and the connecting shaft 107 is fixedly connected to the output shaft of the power mechanism 103. Figure 1 As shown.

[0035] Additionally, a manual crank 106 can be installed on the outer side of the bracket 102. The inner end of the crank 106 is inserted into the bracket 102 and detachably connected to the connecting shaft 107. The cable is wound up by manually rotating the I-beam wheel using the crank, replacing the power mechanism 103. The specific structure is as follows: Figure 2 and Figure 4 As shown.

[0036] The second aspect of this utility model is as follows: Figure 3 , Figure 4 and Figure 5 As shown, by setting a linkage mechanism between the connecting shaft 107 and the intermediate roller 105, during normal cable winding, the linkage mechanism can keep the connecting shaft 107 and the intermediate roller 105 relatively fixed, thereby allowing the driving force of the drive mechanism to be transmitted to the I-beam 104, causing the I-beam 104 to rotate and wind the cable. However, when subjected to greater resistance, the linkage mechanism loses its fixed connection function, allowing relative rotation between the connecting shaft 107 and the I-beam 104. To achieve this function, this embodiment provides a specific structure for the linkage mechanism.

[0037] The linkage mechanism includes ball bearings 108 movably connected to the outer surface of the connecting shaft 107, and a groove on the inner wall of the intermediate roller 105 that mates with the ball bearings 108. Several ball bearings 108 are provided, and several grooves on the inner wall of the intermediate roller 105 are provided in the same number and corresponding positions as the ball bearings 108.

[0038] In addition, the connecting shaft 107 has a ball groove 109 inside, and the ball 108 is movably connected in the ball groove 109. Below the ball 108, there is a support plate 110, which is slidably connected in the ball groove 109. A spring 111 is also provided in the ball groove 109, and the upper and lower ends of the spring 111 are respectively connected to the bottom of the support plate 110 and the inner end of the ball groove 109.

[0039] The linkage mechanism employs ball bearings 108 and corresponding slots. Additionally, the connecting shaft 107 has a ball bearing groove 109 inside, with the ball bearings 108 movably connected within this groove. A spring 111 holds the ball bearings 108 in place. When resistance is low, the ball bearings 108 remain in the groove, allowing the connecting shaft 107 to rotate the I-beam 104. However, when the cable is secured, significant resistance occurs, causing the ball bearings 108 to fall into the ball bearing groove 109 and disengage. At this point, the I-beam 104 and the connecting shaft 107 are no longer rigidly connected, and the connecting shaft 107 will rotate freely inside the I-beam 104. The I-beam 104 will then stop rotating, halting cable winding and preventing excessive pulling force, thus providing a safety protection function.

[0040] In summary, this invention sets the intermediate roller 105 of the I-beam spool 104 as a tubular component with open ends, and sets the transmission relationship between the connecting shaft 107 and the I-beam spool 104 as a rotatable connection. This eliminates the rigid connection between the I-beam spool 104 and the connecting shaft 107, allowing the connecting shaft 107 to rotate freely inside the I-beam spool 104 under significant resistance, preventing hard pulling and effectively protecting the cable and the take-up machine itself. A linkage mechanism is provided between the connecting shaft 107 and the intermediate roller 105. During normal take-up, the linkage mechanism keeps the connecting shaft 107 and the intermediate roller 105 relatively fixed, allowing the driving force of the drive mechanism to be transmitted to the I-beam spool 104, causing it to rotate and wind the cable. Under significant resistance, the linkage mechanism loses its fixed connection function, allowing relative rotation between the connecting shaft 107 and the I-beam spool 104. The linkage mechanism employs ball bearings 108 and corresponding slots. Additionally, the connecting shaft 107 has a ball bearing groove 109 inside, with the ball bearings 108 movably connected within this groove. A spring 111 holds the ball bearings 108 in place. When resistance is low, the ball bearings 108 remain in the groove, allowing the connecting shaft 107 to rotate the I-beam 104. However, when encountering significant resistance, the ball bearings 108 are pressed into the ball bearing groove 109 and disengage from the groove. At this point, the I-beam 104 and the connecting shaft 107 are no longer rigidly connected, and the connecting shaft 107 will spin freely inside the I-beam 104. The I-beam 104 will then stop rotating, halting the winding process and preventing excessive pulling force, thus providing a safety protection function.
