Description

Technical Field

[0001] This utility model relates to the field of coal mine construction technology, specifically to a cable reel device. Background Technology

[0002] In many fields of modern engineering construction, such as complex scenarios like underground coal mine operations, cable laying is of paramount importance. In these scenarios, cables must be laid out in an orderly manner using cable reeling devices, which places stringent requirements on the performance of these devices.

[0003] Typically, cable reeling devices consist of a tray structure on which the cable is placed. The cable is then reeled in and out by rotating the tray. In scenarios such as coal mines, non-coal mines, and construction projects, the weight of cables often exceeds 10 tons. However, existing devices generally suffer from insufficient load-bearing capacity, making cable reeling and laying operations difficult and unable to meet the laying requirements of large-tonnage cables. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a cable reeling device is provided. The cable reeling device includes: a base plate; a support plate rotatably connected to the base plate, wherein a reeling space for placing cables is formed on the side of the support plate facing away from the base plate; and a roller assembly disposed between the support plate and the base plate, wherein the side of the support plate facing the base plate contacts the roller assembly, and the rolling axis of the roller assembly is perpendicular to the rotation axis of the support plate.

[0005] The cable reeling device provided in this application embodiment has an idler roller assembly positioned between the pallet and the base plate. Its rolling axis is perpendicular to the pallet's rotation axis, which evenly distributes the weight of the cable on the pallet and the pallet, improving the overall load-bearing capacity of the cable reeling device and meeting the load-bearing requirements of cables weighing over 10 tons. Simultaneously, the idler roller assembly significantly reduces the frictional resistance of the pallet during rotation through rolling contact, allowing the pallet to rotate smoothly and flexibly during cable reeling and unloading. Even with extremely heavy cables, reeling and unloading operations can be easily achieved, avoiding rotational jamming or structural damage caused by excessive friction. Furthermore, the plate-like structure of the pallet and base plate provides a stable support foundation for the cable. Combined with the efficient transmission of the idler roller assembly, it ensures safe and efficient reeling and unloading operations in complex environments such as underground coal mines, significantly improving the convenience and reliability of cable laying in engineering projects.

[0006] For example, the idler assembly includes a mounting base and an idler roller, the mounting base being disposed on a base plate, the idler roller being rotatably connected to the mounting base, and a support plate having its side facing the base plate in contact with the idler roller.

[0007] For example, the idler roller and / or mounting base are made of stainless steel.

[0008] For example, there are multiple idler roller assemblies, which are arranged along the rotation direction of the pallet.

[0009] For example, there are six idler roller assemblies, and the included angle between the rolling axes of two adjacent idler roller assemblies is 55° to 65°.

[0010] For example, a support rod is connected to the base plate, and a ball bearing assembly is fitted onto the support rod. The ball bearing assembly is connected to the support plate.

[0011] For example, the ball bearing assembly includes a bearing element, balls, and a connecting flange. The bearing element is sleeved outside the support rod, the connecting flange is sleeved outside the bearing element, the balls are disposed between the bearing element and the connecting flange, and the connecting flange is connected to the support plate.

[0012] For example, openings are provided on the tray and / or base plate.

[0013] For example, the pallet and / or base plate are racetrack shaped.

[0014] For example, the pallet and / or base plate are made of steel alloy.

[0023] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0024] This utility model provides a cable reel device. Referring to the reference... Figure 1 and Figure 2 The cable coiling device 10 may include a base plate 110, a support plate 120, and an idler roller assembly 130. The support plate 120 is rotatably connected to the base plate 110, and a coiling space 1201 for placing cables is formed on the side of the support plate 120 facing away from the base plate 110, meaning the cables can be coiled in the coiling space 1201. The support plate 120 and the base plate 110 can be plates of the same shape. The idler roller assembly 130 can be disposed between the support plate 120 and the base plate 110, with the side of the support plate 120 facing the base plate 110 in contact with the idler roller assembly 130. The rolling axis of the idler roller assembly 130 and the rotation axis of the support plate 120 can be perpendicular. The idler roller assembly 130 is typically made of metal, cylindrical, and has a smooth surface. The idler roller assembly 130 has strong pressure resistance and can stably support the support plate 120 and the cables placed on it. Even under long-term load, it is not easily deformed, ensuring the reliability and stability of the device. After the cable is placed on the tray 120, the tray 120 bears pressure and comes into contact with the roller assembly 130. The roller assembly 130 can play a supporting role. At the same time, since the rolling axis of the roller assembly 130 is perpendicular to the rotation axis of the tray 120, the roller assembly 130 rolls when the tray 120 rotates, making the rotation of the tray 120 easier and smoother. In other words, the cable winding and unwinding process in the winding space 1201 can be easier and more convenient.

[0025] The cable reeling device 10 provided in this application embodiment has an idler roller assembly 130 disposed between a pallet 120 and a base plate 110. The roller assembly 130's rolling axis is perpendicular to the rotation axis of the pallet 120, which evenly distributes the weight of the pallet 120 and the cable on it, improving the overall load-bearing capacity of the cable reeling device 10 and meeting the load-bearing requirements of large-tonnage cables exceeding 10 tons. Simultaneously, the idler roller assembly 130 significantly reduces the frictional resistance of the pallet 120 during rotation through rolling contact, allowing the pallet 120 to rotate smoothly and flexibly during cable reeling and unloading. Even with extremely heavy cables, reeling and unloading operations can be easily achieved, avoiding rotational jamming or structural damage caused by excessive friction. Furthermore, the plate-like structure of the pallet 120 and the base plate 110 provides a stable support foundation for the cable. Combined with the efficient transmission of the idler roller assembly 130, it ensures safe and efficient reeling and unloading operations in complex environments such as underground coal mines, significantly improving the convenience and reliability of cable laying in engineering projects.

[0026] For example, in conjunction with reference Figure 1 and Figure 2 The idler assembly 130 may include a mounting base 1310 and an idler roller 1320. The mounting base 1310 may be disposed on the base plate 110. The idler roller 1320 is rollably connected to the mounting base 1310. The side of the support plate 120 facing the base plate 110 contacts the idler roller 1320. Specifically, there are two mounting bases 1310, located at opposite ends of the axial direction of the idler roller 1320. The mounting bases 1310 are welded to the base plate 110. The mounting base 1310 may have a slot, into which a portion of the idler roller 1320 is installed to ensure a secure connection between the mounting base 1310 and the idler roller 1320. The idler roller 1320 is spaced apart from the base plate 110. For example, the distance between the bottom edge of the idler roller 1320 and the base plate 110 is 5 cm to better ensure the rolling of the idler roller 1320. For example, the height of the mounting base 1310 can be 150mm, and the width of the mounting base 1310 can be 120mm. For example, the idler roller 1320 can be a mining stainless steel idler roller 1320. The dimensions of the idler roller 1320 can be φ159*740mm. This configuration of the idler roller assembly 130 can ensure the stability of the connection between the idler roller assembly 130 and the base plate 110, thereby ensuring the stability of the support for the pallet 120 and making the cable coiling process safer.

[0027] For example, refer to Figure 2The idler roller 1320 and / or mounting base 1310 are made of stainless steel. Preferably, both the idler roller 1320 and the mounting base 1310 are made of stainless steel. Stainless steel ensures that the idler roller assembly 130 has good load-bearing capacity, is not easily deformed during use, and ensures the stable operation of the cable reel device 10. For example, the idler roller assembly 130 can be made of 45# steel. 45# steel, i.e., medium carbon steel, has excellent comprehensive mechanical properties after quenching and tempering (quenching + high-temperature tempering), and its surface hardness can be further improved (up to HRC45-55) through high-frequency quenching, making it suitable for heavy-load or high-wear conditions (such as roadways with large coal transport volumes and coarse particles). Alternatively, the idler roller assembly 130 can be made of 40Cr alloy quenched and tempered steel. Alloy quenched and tempered steel has higher wear resistance and strength, making it better suited for extreme conditions (such as the main conveyor belt in large coal mines).

[0028] For example, in conjunction with reference Figure 1 and Figure 2 There are multiple idler roller assemblies 130, which are arranged along the rotation direction of the pallet 120. The arrangement of multiple idler roller assemblies 130 along the rotation direction of the pallet 120 can better distribute the weight of the cable evenly and further ensure the overall load-bearing capacity of the cable reel device 10.

[0029] For example, refer to Figure 2 There are six idler roller assemblies 130, and the included angle between the rolling axes of two adjacent idler roller assemblies 130 is 55° to 65°. Preferably, the included angle between the rolling axes of two adjacent idler roller assemblies 130 is 60°. Thus, the shape formed by the multiple idler roller assemblies 130 is close to an equilateral hexagon, which can balance the force, improve the load-bearing stability of the cable reeling device 10, and avoid structural deformation caused by local overload. At the same time, the reasonable angle setting can make the rolling resistance of the idler rollers 1320 uniform, and the rotation of the pallet 120 smoother, reducing the risk of jamming or tilting caused by uneven force during the winding and unwinding process. This is suitable for complex working conditions such as underground coal mines, ensuring efficient and safe winding and unwinding of large-diameter cables and improving construction reliability. In an embodiment not shown, there can be four idler roller assemblies, which are spaced apart from each other.

[0030] For example, in conjunction with reference Figure 1 and Figure 3A support rod 140 can be connected to the base plate 110. A ball bearing assembly 150 can be fitted over the support rod 140 and connected to the support plate 120. For example, the support rod 140 can be a DN100mm stainless steel pipe. The support rod 140 can pass through the base plate 110 and the support plate 120, and its bottom is welded to the base plate 110. The ball bearing assembly 150 utilizes the rolling friction of the balls 1520 to replace traditional sliding friction, significantly reducing the rotational resistance of the support plate 120 and making cable winding and unwinding operations more effortless and flexible. This cable winding device 10 can adapt to cables of different weights, especially in scenarios with frequent rotation, ensuring the long-term stable operation of the support plate 120. The support rod 140 enables the base plate 110 and the support plate 120 to form a stable frame, ensuring the safe and reliable operation of the cable winding device 10.

[0031] For example, in conjunction with reference Figure 1 and Figure 3 The ball bearing assembly 150 may include a bearing element 1510, balls 1520, and a connecting flange 1530. The bearing element 1510 may be sleeved on the support rod 140, and the connecting flange 1530 may be sleeved on the bearing element 1510. The balls 1520 may be disposed between the bearing element 1510 and the connecting flange 1530, and the connecting flange 1530 is connected to the support plate 120. Specifically, the balls 1520 may be installed inside the connecting flange 1530, and the outside of the connecting flange 1530 may be connected to the support plate 120; alternatively, the bottom of the connecting flange 1530 may be connected to the support plate 120. The connecting flange 1530 is welded to the support plate 120. For example, the support plate 120 has an opening at its center, and the connecting flange 1530 is connected to the structure corresponding to the opening. The connecting flange 1530 can better avoid local deformation caused by stress concentration. The connecting flange 1530 can better ensure assembly accuracy, ensure that the rotation axis of the pallet 120 coincides with the bearing center, reduce vibration and noise caused by off-center load, extend bearing life, and is suitable for stable operation in humid and vibrating environments downhole.

[0032] For example, refer to Figure 2The pallet 120 and / or base plate 110 are provided with openings 1110. There can be four openings 1110 arranged opposite to each other. The openings on the pallet 120 can be used for connecting external devices. For example, during operation, the armored cable reel can be securely connected to the pallet 120 with the help of chains, so that the two rotate synchronously, improving rotational stability and ensuring the safe and efficient operation of cable winding and unwinding. The openings 1110 on the base plate 110 serve the following functions: during operation, the base plate 110 can be reinforced by connecting the anchor bolts with chains, preventing displacement of the cable reel device 10 and ensuring stable operation of the device; during disassembly and installation, the openings 1110 can serve as lifting points, facilitating movement with lifting equipment and improving operational convenience.

[0033] For example, in conjunction with reference Figure 1 and Figure 2 The pallet 120 and / or base plate 110 can be racetrack-shaped. The arc in the racetrack shape can be a semicircle with a radius of 500mm. This design allows the open area formed on the sides to directly expose the underlying stainless steel idler roller 1320, facilitating operator observation of the roller's operating status and timely detection of abnormalities such as damage or jamming, thus preventing equipment damage caused by hidden faults. Furthermore, when the pallet 120 and base plate 110 are not overlapping, the rotation radius of the cable reel device 10 naturally expands along the edge of the racetrack shape. This increased physical space creates a safety warning area, reminding operators to maintain a safe distance and effectively reducing the risk of collisions caused by close-range operations, thereby improving construction safety.

[0034] For example, the support plate 120 and / or the base plate 110 are made of steel alloy. Steel alloy has high strength and good toughness, which can effectively improve the load-bearing capacity of the support plate 120 and the base plate 110, and has strong resistance to deformation, ensuring stable operation of the device under heavy loads and guaranteeing the safe and reliable operation of the cable reeling device 10. For example, the support plate 120 and / or the base plate 110 can be made of Q345 steel, which has good toughness and weldability, and can better guarantee the load-bearing capacity of the cable reeling device 10. The structure, dimensions, and materials of the support plate 120 and the base plate 110 can be completely identical. The thickness can both be 30mm, the length can both be 3200mm, and the width can both be 2200mm. This allows them to better withstand the weight of armored cable reels exceeding 10 tons. Furthermore, the thicker support plate 120 and base plate 110 allow for a greater overall weight of the cable reeling device, and together they form a base, making the cable reeling device 10 more stable. In particular, the combined action of the base plate 110, the support plate 120, and the idler roller assembly 130 disposed between them ensures the load-bearing capacity of the cable reeling device 10.

[0035] The process can be as follows: the cable reeling device 10 and the ground winch are placed almost side by side and parallel. Before operation, ground anchors need to be installed around the base plate 110 of the cable reeling device 10. That is, the iron chain passes through the opening 1110 and is connected to the ground anchor and tightened into one piece to ensure that the base plate 110 does not shift. In actual operation, the wire rope ends of the ground winch and the underground winch are tied to the same end of the armored cable. Every 50m, a self-made wire rope clamp is used to simultaneously clamp the wire rope and the armored cable, so that the two form an approximately parallel line and slowly descend in the auxiliary inclined shaft. The auxiliary inclined shaft is 820 meters long and has an inclination angle of 15°. In the initial stage (0-400m section), the underground winch is the main source of traction. When the cable is lowered to 400m, the ground winch (placed parallel to the cable reeling device 10) begins to provide traction. At this time, because the armored cable has a large self-weight, the winch needs to run slowly to control the lowering speed, while the underground winch is only responsible for recovering the wire rope.

[0036] The cable reeling device 10 operates as follows: the pallet 120 moves slowly in a circular motion around the support rod 140, and the armored cable reel placed on the pallet 120 rotates synchronously with it; the base plate 110 is fixed by ground anchors, forming a stable and immovable foundation; the roller assembly 130 supports the pallet 120 and rotates synchronously under external traction, which reduces frictional resistance and significantly improves the load-bearing capacity of the cable reeling device 10 through multi-point contact; during rotation, the ball bearing assembly 150 further reduces the rotational resistance of the pallet 120, allowing the pallet 120 to rotate flexibly. Thus, with the assistance of the double winch traction, the armored cable is safely lowered.
