Description

Technical Field

[0001] The utility model relates to the technical field of skid-mounted chemical industry equipment, in particular to an autonomous wire management device for a cable drum. Background Art

[0002] During the operation of skid-mounted chemical industrial equipment, due to the limitations of the industrial environment and site, cables and other facilities are needed to extend the operating range. The cable retractor is needed to retract and release the cables. During the cable retraction and release process, various factors such as friction, collision, and winding angle cause the cables to become tangled and unevenly arranged. This often leads to space waste and difficulty in cable management. When the cables are retracted and released again, they need to be manually organized, which increases unnecessary workload.

[0003] The existing wire management structure in the prior art usually requires a servo motor to realize wire management control based on PLC. For example, Chinese patent CN220087704U discloses a wire management structure for a PLC control cabinet, including: a wire card, the outer walls of both sides of the wire card are fixed with hanging ears, one side of the hanging ear is installed with a wire fixing plate by bolts, an arc-shaped connecting plate is fixed at the connection between the fixing plate and the hanging ear, a slot is provided on the outer wall of one side of the fixing plate, and slide rails are fixed on the inner walls of both sides of the slot, a slider is arranged inside the slot, and a slide groove is provided at the connection between the slider and the slide rail. The wire management structure for the PLC control cabinet is provided with a wire clamp, which is opened and closed by sliding the slider on the slide rail. The slider enables the wire clamp to move back and forth in the slot to prevent the slider and the wire clamp from falling out of the slot, and the wire clamp is kept closed by the elastic force of the spring to prevent the cable from falling out from the inside of the wire clamp after being fixed, and the cable can be pulled out by simply dragging it outward, which is convenient and easy to operate.

[0004] This type of solution is a PLC-based self-service wiring structure, which requires a large number of electrical components. At the same time, the wiring structure needs to be synchronized with the rotation of the cable drum, so programming control is required. Although precise control can be achieved, the implementation cost is relatively high.

[0005] Therefore, there is an urgent need for an autonomous wire management device for a cable reel, which can comb and arrange the winding of the cable reel group, does not require the use of PLC for control, has a simple structure and low manufacturing cost.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0033] like Figure 1 , 2As shown, the utility model provides an autonomous wire management device for a cable drum 100, which comprises at least a driving gear 1, a driven gear 2 and a wire management groove 4. The driving gear 1 is coaxially arranged with the cable drum 100 and rotates synchronously with the cable drum 100 when winding and releasing the wire. The driven gear 2 is arranged on the front side of the base frame 101 of the cable drum 100 (i.e. Figure 1 The driving gear 2 is driven by a chain or a synchronous belt 3 ( Figure 1 The dashed line indicates Figure 2 The driven gear 2 is fixedly connected to the driven shaft 21, and the driven shaft 21 has an external thread (not shown in the figure). The wire management slot 4 is a shell structure and is on the front side (i.e. Figure 2 The driven shaft 21 passes through the cable management slot 4 and the external thread of the driven shaft 21 and the driven shaft hole 411 (reference Figure 3 ) is adapted to the internal thread of the driven shaft 21; during the rotation of the driven shaft 21, the external thread of the driven shaft 21 and the internal thread of the driven shaft hole 411 cooperate, the wire management groove 4 can extend in the direction of the driven shaft 21 (ie Figure 2 Horizontal direction in the image.

[0034] By adopting the above technical solution, the utility model realizes the horizontal movement of the cable management trough 4 through the cooperation of the driving gear 1 and the driven gear 2 and the external thread setting of the driven shaft 21, thereby realizing the synchronization of the translation of the cable management trough and the rotation of the cable drum, that is, as the cable drum rotates, the outlet end of the winding wire can translate autonomously so as to always adapt to the corresponding winding position, effectively avoiding the occurrence of cable knotting and uneven arrangement due to friction, collision, winding angle and other factors during the cable collection and release process. It not only has the function of combing and arranging the winding of the cable drum 100 wire group, but also does not need to be controlled by PLC, has a simple structure and low manufacturing cost.

[0035] Furthermore, the driving shaft fixedly connected to the driving gear 1 is connected to the motor 102, which is used to control the rotation of the cable drum 100, so as to realize the cable winding and releasing. The driving shaft can be fixedly connected to the base frame 101 through a bearing seat. When the cable drum 100 rotates, there is no relative movement between the driving shaft and the driving gear 1. The driven shaft 21 can be connected to the base frame 101 through a bearing and can rotate freely. There is no relative movement between the driven shaft 21 and the driven gear 2.

[0036] Further Figure 2As shown, in order to ensure the stability of the horizontal movement of the cable management trough 4, the cable management trough 4 is also provided with a guide rod 5, and the number of the guide rods 5 is two and they are respectively arranged directly above and directly below the driven shaft 21, and are arranged parallel to the driven shaft 21. By setting the upper and lower guide rods, the movement direction of the cable management trough 4 can always be guided to be horizontal, so that the thread feed of the cable management trough on the driven shaft 21 can be more stable. Preferably, but not restrictively, the guide rod 5 is a smooth rod body of equal diameter and can be fixed on the base frame 101. Furthermore, the guide rod 5 is preferably provided with a ball (not shown in the figure) in the guide hole 412 of the cable management trough 4, and when the cable management trough 4 is translated along the guide rod 5, rolling friction can be formed at the contact portion between the two. Through such a setting, the friction can be effectively reduced, making the guide sliding smoother.

[0037] Further Figure 3 As shown, the cable outlet of the cable management trough 4 is preferably a square hole 41. A cable tensioning assembly may be provided in the square hole 41, so that the cable passing through the square hole can be tightened during the process of winding and releasing the wires, so that it does not loosen and fits tightly to the cable reel sleeve. Further, preferably but not restrictively, the cable tensioning assembly may include a tensioning wheel 6 and a spring 7. Among them, the number of tensioning wheels 6 is two and they are rotatably connected to the inner wall of the square hole 41. Specifically, they can be connected through ball bearings 61 located on both sides of the tensioning wheel 6, and the ball bearings 61 are arranged at the slot 410 of the inner wall of the square hole 41. The number of springs 7 is equivalent to the number of ball bearings (both are 4), and the springs 7 are also arranged at the slot 410 of the inner wall of the square hole 41. The free end of the spring 7 is fixedly connected to the ball bearing 61. During the process of winding and releasing the wires, the two tensioning wheels 6 can move up and down and tighten the cable 103 under the elastic force of the springs.

[0038] The utility model assumes that the winding width length of the cable drum 100 is L, the number of turns of a single layer of tight winding is N, the radius of the driving gear is R, the radius of the driven gear is r, and the pitch of the driven shaft is d. When N*R*d=L*r, the synchronization of the cable management trough 4 and the cable drum 100 is satisfied. In other words, the synchronization of the cable management trough 4 and the cable drum 100 can be satisfied by satisfying the above quantitative relationship, that is, while the motor 102 drives the cable drum 100 to rotate forward and reverse to achieve the collection and release of the wires, it drives the left and right horizontal movement of the cable management trough 4, thereby achieving a uniform and tight arrangement of the winding of the cable drum 100, and avoiding the occurrence of cable knotting and uneven arrangement due to friction, collision, winding angle and other factors during the process of cable collection and release to the greatest extent.
