Description

Technical Field

[0001] The invention relates to the field of coal mining, and in particular to a coal mining machine cable turning device. Background Art

[0002] In the field of coal mining, coal mining machines are key equipment for realizing mechanized mining. With the continuous advancement of coal mining technology and the pursuit of high efficiency and high safety, the functions and complexity of coal mining machines are gradually increasing. During operation, coal mining machines need to move back and forth and rotate frequently to adapt to the working surface conditions of the mine. This movement and rotation puts higher requirements on the management and protection of cables.

[0003] Improper cable management is one of the common problems in the coal mining process, especially in the cable management of coal mining machines. When the coal mining machine is operating, the cable not only needs to withstand a large tensile force, but also needs to be dragged as the machine moves. It is easy to wear, entangle, or even break in a complex underground environment. Especially when the coal mining machine moves back and forth along the working face, the dragging and flipping of the cable is particularly critical. Unreasonable cable dragging methods will not only increase the risk of cable damage, but may also cause failure of the cable clamp or cable support mechanism due to the cable being too long or too heavy, thereby affecting the normal operation of the coal mining machine and the stability of power transmission.

[0004] Traditional cable management methods, such as simple cable drag chains, cable reels or fixed cable clamps, often have the following shortcomings:

[0005] First, these methods do not accurately control the drag force of the cable, which can easily cause excessive bending of the cable, especially under the condition of frequent movement of the coal mining machine;

[0006] Second, the installation, adjustment and maintenance of these methods are relatively complicated, which poses certain obstacles to the rapid operation of coal mines and the efficient use of equipment. Summary of the invention

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] In the field of coal mining, coal mining machines are key equipment for realizing mechanized mining. With the continuous advancement of coal mining technology and the pursuit of high efficiency and high safety, the functions and complexity of coal mining machines are gradually increasing. During operation, coal mining machines need to move back and forth and rotate frequently to adapt to the working surface conditions of the mine. This movement and rotation puts higher requirements on the management and protection of cables.

[0052] Improper cable management is one of the common problems in the coal mining process, especially in the cable management of coal mining machines. When the coal mining machine is operating, the cable not only needs to withstand a large tensile force, but also needs to be dragged as the machine moves. It is easy to wear, entangle, or even break in a complex underground environment. Especially when the coal mining machine moves back and forth along the working face, the dragging and flipping of the cable is particularly critical. Unreasonable cable dragging methods will not only increase the risk of cable damage, but may also cause failure of the cable clamp or cable support mechanism due to the cable being too long or too heavy, thereby affecting the normal operation of the coal mining machine and the stability of power transmission.

[0053] Traditional cable management methods, such as simple cable drag chains, cable reels or fixed cable clamps, often have the following shortcomings:

[0054] First, these methods do not accurately control the drag force of the cable, which can easily cause excessive bending of the cable, especially under the condition of frequent movement of the coal mining machine;

[0055] Second, the installation, adjustment and maintenance of these methods are relatively complicated, which poses certain obstacles to the rapid operation of coal mines and the efficient use of equipment.

[0056] The main purpose of the present invention is to provide a coal mining machine cable turning device to solve the problem in the prior art that the cable is easily damaged during the turning and dragging process.

[0057] The cable turning device for a coal mining machine provided in the present application comprises a bearing unit 7, the bearing unit 7 comprises a bearing plate 701, and a bearing column 702 arranged on the bearing plate 701, the bearing column 702 is used for sleeve installation of the cable;

[0058] A limiting unit, which is disposed on the bearing column 702 to limit the displacement of the cable along the extending direction of the bearing column 702;

[0059] The driving unit has a driving end connected to the carrying unit 7 to drive the carrying unit 7 to drive the cable to operate, including extending, contracting or flipping.

[0060] Specifically, Figure 1 As shown, the cable turning device provided in the present application includes a bearing unit 7, and the bearing unit 7 includes a bearing plate 701, such as Figure 1 and Figure 2 As shown, a bearing column 702 is arranged on one side of the bearing plate 701, and the extension direction of the bearing column 702 is perpendicular to the bearing plate 701. The bearing column 702 is used to sleeve the cable. A limiting unit is provided on the bearing column 702, which can limit the movement of the cable along the extension direction of the bearing column 702. It also includes a driving unit connected to the bearing unit 7, which is used to drive the bearing unit 7 to carry the cable to perform operations, such as extending, contracting or flipping the cable.

[0061] The design of the bearing unit 7, especially the vertical arrangement of the bearing plate 701 and the bearing column 702, provides a stable support platform for the cable. The cable is sleeved on the bearing column 702, and the limit unit ensures the stability of the cable along the extension direction of the bearing column 702, avoiding the cable from sliding and falling off during the operation of the coal mining machine, thereby improving the management efficiency and safety of the cable.

[0062] The driving connection between the driving unit and the bearing unit 7 enables the bearing unit 7 to accurately perform corresponding actions as the coal mining machine moves or rotates. This design ensures that the cable can be accurately extended, contracted or turned over according to the working requirements of the coal mining machine, reducing the wear and damage of the cable during the reciprocating operation of the coal mining machine and extending the service life of the cable.

[0063] The integrated design of the cable turning device does not require frequent manual intervention, reducing the interference of cable management on the operation of the coal mining machine, thereby improving the operating efficiency of the coal mining machine. The automatic turning and adjustment of the cable allows the coal mining machine to move more flexibly on complex working surfaces without worrying about the limitations of the cable, greatly improving the mining speed and continuity.

[0064] The combined use of the bearing unit 7 and the limiting unit, as well as the precise control of the driving unit, enables the device to adapt to coal mining machines of different models and sizes, as well as to face the changing mine working environment. The limiting unit can be adjusted according to the diameter of the cable and the size of the bearing column 702, ensuring that the cable can be effectively protected and managed under various working conditions.

[0065] By reducing the manual management of cables, the equipment failure rate caused by improper cable management is reduced, and the maintenance cost is reduced. At the same time, the use of the cable flip device avoids excessive bending and wear of the cable, reduces the risk of power transmission interruption, and improves the safety of coal mining operations.

[0066] To sum up, the coal mining machine cable flipping device provided in this application not only solves the management problem of the cable during the operation of the coal mining machine, but also improves the safety and service life of the cable, reduces the downtime of the coal mining machine, and improves the efficiency and safety of coal mining, demonstrating its significant technical effect in practical applications.

[0067] Furthermore, the carrying unit 7 further includes:

[0068] A bearing component 703, wherein the bearing component 703 is sleeved on the bearing column 702;

[0069] The limit unit includes:

[0070] The limiting plates 704 are arranged at both ends of the bearing component 703, and the limiting plates 704 and the bearing component 703 together form a rotation space, and the cable is arranged in the rotation space.

[0071] Specifically, Figure 2 As shown, the bearing unit 7 includes a bearing component 703 mounted on a bearing column 702, and the limiting unit includes limiting plates 704 mounted on both ends of the bearing component 703. The limiting plates 704 are in a circular shape, and the diameter of the limiting plates 704 is greater than the diameter of the bearing component 703. During cable operation, the existence of the limiting plates 704 can prevent the cable from being separated from the bearing component 703.

[0072] The bearing component 703 on the bearing column 702 provides a low-friction, high-load support platform for the cable. The bearing component 703 can rotate freely, reducing the friction between the cable and the support structure, reducing the wear of the cable during movement, and extending the service life of the cable.

[0073] The setting of the limiting unit, i.e. the annular limiting plates 704 arranged at both ends of the bearing component 703, whose diameter is larger than the bearing component 703, effectively prevents the cable from slipping off the bearing column 702. This design ensures the position stability of the cable during operation. Even when the coal mining machine moves quickly or turns, the cable can be kept in a limited position, avoiding cable damage and coal mining machine operation interruption caused by accidental falling off.

[0074] The cooperation between the bearing unit 7 and the driving unit enables the cable turning device to accurately control the turning angle and speed of the cable according to the operation requirements of the coal mining machine. The bearing component 703 is the core of the cable turning. Its smoothness and stability of rotation ensure the smoothness of the cable during the turning process, reducing the impact on the cable caused by excessive or unstable turning action.

[0075] By adjusting the distance between the limit plate 704 and the bearing column 702 and selecting bearing components 703 of different specifications, the device can adapt to cables of different diameters and cope with various operation modes of the coal mining machine. The operator can quickly adjust the device to adapt to different working environments and requirements, thereby improving the flexibility and operating efficiency of the device.

[0076] To sum up, the coal mining machine cable flipping device provided in the present application realizes the stable support and precise limitation of the cable through the coordinated action of the load-bearing unit 7 and the limiting unit, improves the safety and reliability of the cable during the operation of the coal mining machine, optimizes the cable management process, and demonstrates significant technical effects and application value.

[0077] Furthermore, the limiting unit also includes:

[0078] At least two positioning plates 705, at least two positioning plates 705 are respectively and correspondingly arranged on the two limiting plates 704;

[0079] At least two positioning holes 706, at least two positioning holes 706 are respectively provided on the two positioning plates 705 in a one-to-one correspondence;

[0080] The limiting rod 707 is detachably disposed in at least two positioning holes 706 .

[0081] Specifically, Figure 3 , Figure 4 , Figure 5 As shown, the limit unit also includes a positioning plate 705 arranged on the outer edge of the limit plate 704, and each limit plate 704 is respectively provided with a positioning plate 705, a positioning hole 706 is opened on the positioning plate 705, and also includes a limit rod 707, which is passed through the two positioning holes 706 to prevent the cable from detaching from the bearing component 703 during operation.

[0082] The arrangement of the positioning plate 705 in the limiting unit and the positioning hole 706 opened on the positioning plate 705 provide a precise fixing point for the cable. By inserting the limiting rod 707 into the two positioning holes 706, the fixed position of the cable on the bearing column 702 can be ensured, and the cable can be kept in the best working state even when the coal mining machine moves at high speed or in complex terrain conditions, effectively avoiding the deviation or falling off of the cable position.

[0083] The installation of the limit rod 707 forms a physical barrier to prevent the cable from accidentally slipping off during operation. This design is particularly suitable for working conditions where the cable is long and heavy, and can effectively prevent the cable from detaching from the bearing column 702 due to gravity or external force, reducing the risk of cable damage and ensuring the continuity and stability of the cable power supply.

[0084] The combination of the positioning plate 705 and the limiting rod 707 ensures accurate control of the cable during the flipping process. No matter what kind of flipping operation the cable needs to undergo, the limiting unit can keep the cable on a defined flipping path, avoiding flipping errors caused by an unfixed cable position and improving the accuracy and efficiency of the cable flipping operation.

[0085] To sum up, the coal mining machine cable turning device of the present application, through the refined design of the limit unit, realizes the stable bearing, precise positioning and safety protection of the cable, significantly improves the efficiency of cable management and the safety of coal mining machine operation, and demonstrates its remarkable technical effects and application value in the field of coal mining.

[0086] Further, the driving unit comprises: a driving component 1, a driving end of the driving component 1 is connected to a first gear structure 2;

[0087] A second gear structure 4, the second gear structure 4 is connected to the first gear structure 2 via a synchronous belt 3;

[0088] The second gear structure 4 is used to be connected to the carrying unit 7 .

[0089] Specifically, Figure 6 and Figure 7 As shown, the driving unit includes a driving component 1, which is a driving motor in this embodiment. The driving end of the driving component 1 is connected to a first gear structure 2, and the first gear structure 2 is meshed with a second gear structure 4. The second gear structure 4 is used to be connected to a carrying unit 7. The first gear structure 2 and the second gear structure 4 are connected by a synchronous belt 3 to achieve synchronous rotation.

[0090] The drive unit uses a drive motor as a power source, and realizes efficient power transmission through the precise meshing between the first gear structure 2 and the second gear structure 4. The use of the synchronous belt 3 ensures the synchronous rotation of the first gear structure 2 and the second gear structure 4, avoids the speed difference during the power transmission process, and maintains the continuity and accuracy of the cable flipping action.

[0091] The connection between the second gear structure 4 and the bearing unit 7 makes the rotation of the bearing unit 7 more stable. This design reduces the swing of the bearing column 702 caused by gear jumping or uneven power, keeps the cable smooth during the flipping process, reduces unnecessary pulling or bending of the cable, and prolongs the service life of the cable.

[0092] As the core of the drive unit, the drive motor can accurately adjust the speed and angle of the cable flipping according to the working requirements of the coal mining machine. Whether it is required to flip quickly or move slowly, the drive motor can provide suitable power output, allowing the cable flipping device to flexibly respond to various working conditions, improving the efficiency of cable management and the flexibility of coal mining machine operations.

[0093] The synergy between the drive unit and the carrier unit 7 simplifies the cable management process. Through the automatic flipping control of the drive unit, the staff does not need to frequently manually adjust the position of the cable, which reduces the labor intensity of manual management, reduces operating errors, and improves the safety and efficiency of the operation.

[0094] To sum up, the coal mining machine cable turning device of the present application, through the efficient design of the drive unit, realizes the precise control and stable execution of the cable turning operation, significantly improves the efficiency of cable management and the safety of coal mining machine operation, and demonstrates its significant technical effects and application value in practical applications.

[0095] Furthermore, the driving unit further comprises: a fixing column, which is arranged on the second gear structure 4, and a fixing hole is arranged on the bearing plate 701, and the fixing hole cooperates with the fixing column to fix the bearing unit 7 and the limiting unit on the driving unit.

[0096] Specifically, the driving unit further includes a fixing column arranged on the second gear structure 4, such as Figure 2 As shown, a fixing hole is provided on the bearing plate 701 , and the fixing hole can be used in conjunction with a fixing column to fix the bearing unit 7 and the limiting unit on the driving unit.

[0097] The use of the fixing column and the fixing hole between the driving unit and the bearing unit 7 forms a mechanical stable connection, which ensures the stability of the bearing unit 7 during the cable turning process and reduces the displacement of the bearing unit 7 caused by movement or vibration. This design enhances the overall structural stability of the device, and the cable turning device can maintain a good working condition even in the complex environment and high-intensity working conditions when the coal mining machine is working.

[0098] The precise alignment of the fixing column and the fixing hole on the bearing plate 701 provides a reference point for the rotation of the bearing unit 7, which helps to improve the accuracy and predictability of the cable flipping. This allows the cable to rotate according to the preset path and angle during the flipping process, avoiding deviation of the cable position, reducing the risk of cable damage, and ensuring the continuity and stability of the cable power supply.

[0099] To sum up, the coal mining machine cable turning device of the present application, through the precise matching of the fixed column on the driving unit and the fixed hole on the supporting plate 701, not only enhances the structural stability of the device and the accuracy of cable turning, but also simplifies the assembly and disassembly process of the device, improves the efficiency of cable management and the safety of coal mining machine operation, and demonstrates significant technical effects and application value.

[0100] Furthermore, the cable turning device also includes: a first mounting structure 6, and the first mounting structure 6 is used to install the cable turning device on a first mounting position of the coal mining machine.

[0103] The baffle 603 is disposed on an end of the mounting rod 602 away from the first mounting plate 601 to limit the displacement of the second gear structure 4 along the extending direction of the mounting rod 602 .

[0104] Specifically, the cable turning device also includes a first mounting structure 6, which includes a first strip-shaped mounting plate 601, a mounting rod 602 is provided in the middle of the first mounting plate 601, the first mounting plate 601 is arranged on the through hole of the second gear structure 4 and can be rotatably mounted on the second gear structure 4, and a baffle 603 is provided at the end of the mounting rod 602 away from the first mounting plate 601, the diameter of the baffle 603 is larger than the diameter of the mounting rod 602, and the baffle 603 is used to limit the displacement of the mounting rod 602 in the extension direction of the mounting rod 602.

[0105] The design of the first mounting plate 601 enables the cable turning device to be quickly and easily installed on a coal mining machine or other supporting structure. The operator only needs to align the first mounting plate 601 with the fixing point on the coal mining machine, insert and fix the mounting rod 602, and the device can be installed. This design greatly simplifies the installation process, reduces the installation difficulty and time cost, and also facilitates the disassembly and storage of the device.

[0106] The setting of the baffle 603 effectively limits the displacement of the mounting rod 602 along its extension direction, ensuring the stability of the cable turning device during operation. This design avoids the device from loosening or falling off during transportation or operation, and enhances the overall reliability and safety of the device.

[0107] The rotatable characteristic of the first mounting structure 6 enables the cable turning device to adapt to the needs of the coal mining machine in different working environments. The device can freely adjust the angle according to the travel direction of the coal mining machine or the change of the working surface to ensure that the cable is always kept in the best turning state, thereby improving the flexibility and working efficiency of the device.

[0108] The cooperation between the first mounting structure 6 and the second gear structure 4 optimizes the power transmission path from the drive unit to the load-bearing unit 7. This design ensures the smooth transmission of power and reduces the loss during the power transmission process. At the same time, the rotatable mounting structure can also reduce the vibration during the cable flipping process and improve the smoothness of the cable flipping.

[0109] To sum up, the coal mining machine cable turning device of the present application, by introducing the first mounting structure 6, not only simplifies the installation and disassembly process of the device, enhances the stability and adaptability of the device, but also optimizes the power transmission path, simplifies the maintenance and adjustment steps, reduces operating costs, and significantly improves the efficiency of cable management and the safety of coal mining machine operations.

[0113] Specifically, the first mounting structure 6 also includes first mounting holes 604 arranged at both ends of the first mounting plate 601, and also includes a first locking member 605 used in conjunction with the first mounting hole 604. By using the first locking member 605 in conjunction with the first mounting hole 604, the first mounting structure 6 can be installed in the first mounting position, wherein the first locking member 605 can be a locking bolt.

[0114] The first mounting hole 604 and the first locking member 605 are used in combination to simplify the connection process between the first mounting structure 6 and the coal mining machine or other supporting structures. The operator only needs to fix the first locking member 605 on the first mounting position through the first mounting hole 604 to complete the installation. This design not only improves the installation speed, but also allows the device to be adjusted on the first mounting position according to actual needs, thereby enhancing the flexibility and application range of the device.

[0115] Through the locking action of the first locking member 605, the first mounting structure 6 can be firmly fixed at the first mounting position, avoiding possible loosening or falling off of the device when the coal mining machine moves at high speed or operates in complex terrain, thereby ensuring the structural stability and reliability of the entire cable turning device.

[0116] The stable installation of the first installation structure 6 provides a more stable control basis for cable flipping. When the device flips the cable, it can be executed more accurately according to the preset path and angle, reducing the cable position deviation caused by the instability of the device, optimizing the cable management process, and improving the operating efficiency and safety of the coal mining machine.

[0117] The use of the first mounting hole 604 and the first locking member 605 enables the device to adapt to a variety of different first mounting positions, increasing the versatility and interchangeability of the device.

[0118] To sum up, the coal mining machine cable turning device of the present application, through the effective cooperation between the first mounting hole 604 and the first locking member 605 in the first mounting structure 6, not only optimizes the installation and adjustment process of the device, enhances the structural stability and the accuracy of cable turning control, but also simplifies the maintenance steps and reduces operating costs.
