Description

Technical Field

[0001] The utility model relates to a cable reel, in particular to a cable reel capable of preventing cables from overheating. Background Art

[0002] A cable reel is a cable winding device that provides power, control power or control signals for large mobile equipment. It is widely used in heavy machinery equipment such as port gantry cranes, container cranes, ship loaders, tower cranes and other similar working conditions. Cable reels are divided into two categories according to the drive form: electric and non-electric, with different characteristics and configurations. For example, electric cable reels include magnetic coupling, torque motor, frequency conversion control and hysteresis types, and non-electric reel cables include elastic, magnetic coupling and heavy hammer types.

[0003] Cables will have a certain amount of energy loss when transmitting current, and these losses are usually manifested as heat energy. When existing cables are wound, they come into contact with bearings and generate greater friction, which causes the cables to overheat. Cable overheating not only affects the life of the cables, but may also cause safety hazards such as short circuits and fires.

[0004] Therefore, it is necessary to design a cable reel that avoids overheating of the cable. Utility Model Content

[0005] In order to overcome the disadvantage of existing cable reels that the cable is overheated due to excessive friction when the cable is wound, the technical problem is to provide a cable reel that can prevent the cable from overheating.

[0006] The technical solution is: a cable reel to prevent cable overheating, including a base, a bracket, a controller, a reel, a fixed block, a servo motor, a support shaft, a rotating rod, a bidirectional screw, a sliding sleeve, a first bearing, a pulley group, a fan and a bidirectional frame. The bracket is fixedly connected to one side of the top of the base in a front-to-back symmetrical manner, a controller is installed on one side of the front bracket, a reel is rotatably connected between the upper parts of the two brackets, reels are connected to the front and rear ends of the reel, a fixed block is fixedly connected to one side of the reel, a servo motor is installed on the other side of the reel, and the output shaft of the servo motor is connected to the rear of the reel. The ends are fixedly connected, and a support shaft is symmetrically fixed to the other side of the top of the base front and back, a rotating rod is rotatably connected between the two support shafts, a bidirectional screw is provided along the circumferential fixed sleeve of the rotating rod, a sliding sleeve is threadedly connected to the bidirectional screw, the lower end of the sliding sleeve is slidably connected to the base through a support rod, a first bearing is rotatably connected to the middle of the sliding sleeve, the rear end of the rotating rod and the rear end of the reel are transmitted through a pulley group, a fan is installed on the base, the air outlet of the fan faces upward, and a bidirectional frame is fixed to the fan, and the two air outlets of the bidirectional frame are respectively facing the upper left sliding sleeve and the upper right reel.

[0007] Furthermore, it also includes a second bearing, and the sliding sleeve is connected to the second bearing in a front-rear sliding manner.

[0008] Furthermore, it also includes a handle, and the handle is fixedly connected to the base in a left-right symmetrical manner.

[0009] Furthermore, the upper portion of the second bearing is rotatable.

[0010] Furthermore, the interior of the drum is hollow, and a plurality of through holes are provided on the exterior of the drum.

[0011] Furthermore, the reel is made of polyvinyl chloride (PVC) with good insulation and wear resistance.

[0012] The utility model has the following advantages: 1. The utility model adds bearings and fans. The bearings limit the position of the cables, reducing the friction generated when the cables are wound up. The fans accelerate the air flow at the cable friction points on the sleeve and at the cable wound up points on the drum, thereby achieving a cooling effect. This solves the problem of overheating of the cables caused by excessive friction when the cables are wound up on existing cable drums. The utility model is efficient, quick and highly practical.

[0013] 2. The utility model further diffuses the heat of the cable through the multiple through holes opened in the reel, which is efficient and labor-saving and improves the heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Embodiment: A cable reel for preventing overheating of a cable, such as Figure 1-Figure 4 As shown, it includes a base 1, a bracket 2, a controller 3, a reel 4, a fixing block 5, a servo motor 6, a support shaft 7, a rotating rod 8, a bidirectional screw 9, a sliding sleeve 10, a first bearing 11, a pulley group 12, a fan 13 and a bidirectional frame 14. The right side of the top of the base 1 is symmetrically connected to the bracket 2 by bolts, the middle part of the front side of the front side bracket 2 is connected to the controller 3 by bolts, and the reel 4 is rotatably connected between the upper parts of the two brackets 2. The interior of the reel 4 is hollow, and a plurality of through holes are opened on the outside of the reel 4. The reel 4 is made of polyvinyl chloride (PVC) with good insulation and wear resistance. The front and rear ends of the reel 4 are fixedly clamped with reels, the front side of the reel 4 is welded with a fixing block 5, the rear side of the reel 4 is connected to the servo motor 6 by bolts, and the servo motor The output shaft of the machine 6 is fixedly connected to the rear end of the reel 4, and a support shaft 7 is symmetrically connected to the left side of the top of the base 1 by bolts. A rotating rod 8 is rotatably connected between the two support shafts 7. The rotating rod 8 is provided with a bidirectional screw 9 along the circumferential fixed sleeve, and a sliding sleeve 10 is threadedly connected to the bidirectional screw 9. The lower end of the sliding sleeve 10 is slidably connected to the base 1 through a support rod, which limits the sliding sleeve 10 to move only forward and backward but not to rotate. A first bearing 11 is rotatably connected to the middle part of the sliding sleeve 10, and the rear end of the rotating rod 8 and the rear end of the reel 4 are driven by a pulley group 12. A fan 13 is bolted to the middle part of the base 1, and the air outlet of the fan 13 faces upward. A bidirectional frame 14 is welded on the top of the fan 13, and the two air outlets of the bidirectional frame 14 are respectively facing the upper left sliding sleeve 10 and the upper right reel 4.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a second bearing 15 is also included. The right part of the sliding sleeve 10 is slidably connected to the second bearing 15 in the front and rear directions, and the upper part of the second bearing 15 is rotatably designed.

[0022] like Figure 1 and Figure 2 As shown, a handle 16 is also included, and the base 1 is fixedly and interlacedly connected with the handle 16 in a bilaterally symmetrical manner.

[0023] When people need to store cables, they can use this device. According to actual needs, place the device horizontally (or install it through screw holes) at the location where it needs to be stored, confirm that there is enough support at the bottom, check the use of the equipment parts, if they are in good condition, turn on the power and start using the device.

[0024] When people need to fix the cable, first pass one end of the cable through the gap between the first bearing 11 and the second bearing 15, then put the cable on the reel in front of the reel 4, and clamp it with the fixing block 5 on the front side to ensure that the cable is fixed. At the same time, in order to avoid the cable from getting knotted or twisted during the insertion process, it is necessary to ensure that there is a certain safety distance between the reel 4 and the surrounding obstacles. After the cable is installed, use a binding belt or a fixing device to fix the cable position on the front side of the reel 4 to prevent it from sliding or moving during work, thereby completing the cable fixing work.

[0025] When people need to wind up (or release) the cable, first check whether the first bearing 11 and the second bearing 15 rotate flexibly and whether the lubrication condition is good. If it is found that the first bearing 11 or the second bearing 15 is stuck or insufficiently lubricated, lubrication maintenance is immediately performed, and a certain amount of lubricant is poured into the first bearing 11 and the second bearing 15 to ensure that the rotation condition is good. Then operate the controller 3 to start the servo motor 6. Since the rear end of the rotating rod 8 and the rear end of the reel 4 are driven by the pulley group 12, the servo motor 6 drives the reel 4 to rotate clockwise. Similarly, the The pulley group 12 will also drive the rotating rod 8 and the bidirectional screw 9 to rotate clockwise at the same time. Since the sliding sleeve 10 and the bidirectional screw 9 are connected in a front-to-back sliding manner, when the bidirectional screw 9 rotates clockwise, the sliding sleeve 10 moves in the direction of the thread engagement, and drives the first bearing 11 and the second bearing 15 to move in a front-to-back range. At this time, the cable is pulled to the right, and then slowly moves to the upper part of the side reel 4, and rotates clockwise into a circle under the fixing action of the fixing block 5 until the reeling is completed, thereby completing the cable winding work. If it needs to be released, the reverse process can be performed.

[0026] When people need to dissipate heat from the cable, since the cable continuously rubs against the bearing during the process of being retracted and released, a certain amount of heat is generated. To avoid overload, the controller 3 can be operated to start the fan 13 in advance. Since a two-way frame 14 is fixedly connected to the top of the fan 13, the two air outlets of the two-way frame 14 are respectively facing the upper left sliding sleeve 10 and the upper right reel 4. When the fan 13 is running, the air flow at the cable friction point on the sliding sleeve 10 and the cable winding point on the reel 4 is accelerated, and a strong air output is quickly generated through mechanical kinetic energy, and the high-temperature and stuffy air inside the equipment is quickly discharged to the outside of the equipment, forming a negative pressure state, thereby introducing outdoor fresh air for forced convection exchange, so as to achieve the effect of reducing the cable temperature. At the same time, the multiple through holes opened in the reel 4 diffuse the heat of the cable, thereby completing the heat dissipation of the cable.

[0027] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
