Description
Technical Field
[0001] The utility model belongs to the technical field of bucket wheel machines, and in particular relates to a towing cable arrangement structure for a bucket wheel machine. Background Art
[0002] Bucket wheel excavators, as an important industrial equipment, play a vital role in thermal power plants, steel mills, ports and other fields. They are mainly used for stacking and reclaiming operations. They are efficient and flexible, and can significantly improve production efficiency. However, the operation of bucket wheel excavators is inseparable from the stable transmission of power and signals, and the towline is the key component to achieve this transmission. During operation, bucket wheel excavators do need to frequently perform large-scale, high-intensity movement and rotation to achieve precise grasping and efficient transportation of materials.
[0003] However, traditional tow cable arrangements often seem unable to cope with such complex and changeable working conditions. If the tow cable is directly dragged on the ground while following the bucket wheel excavator, it can easily be damaged by friction, resulting in increased wear and even the risk of breakage or falling off. In addition, when the bucket wheel excavator encounters external impacts or faces sudden changes in force, traditional tow cable arrangements often lack sufficient buffering and protection mechanisms, making the tow cable more vulnerable to damage. These problems not only affect the normal operating efficiency of the bucket wheel excavator, but also seriously threaten operational safety. Utility Model Content

[0010] Preferably, a guide groove for the pulling head to slide is provided at the bottom of the mounting seat.
[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:
[0012] First, the guide block of this device slides smoothly along the guide ropeway, providing continuous and stable support and guidance for the tow cable. At the same time, the guide groove at the bottom of the mounting seat provides a stable and smooth sliding path for the pulling head, ensuring that the tow cable can move strictly in the predetermined direction and path.

[0024] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0025] The embodiment of the utility model provides a bucket wheel machine towing cable arrangement structure, such as Figure 1-7As shown, it includes a mounting seat 1; two positioning blocks 2 symmetrically arranged on the end sides of the mounting seat 1; a guide ropeway 3 is arranged between the two positioning blocks 2; a guiding mechanism is arranged on the guide ropeway 3; wherein, the guiding mechanism includes: a plurality of guide blocks 4 arranged on the guide ropeway 3; a first assembly seat 5 provided at the bottom position of a plurality of the guide blocks; a second assembly seat 6 is provided on the side of the plurality of the first assembly seats 5 away from the guide block, and a gap is provided between the first assembly seat 5 and the second assembly seat 6 for the towline 7 to pass through; a fastener is provided on the side opposite to the second assembly seat 6 of the plurality of the first assembly seats 5; the fastener includes: a plurality of return springs 8 provided at the bottom position of the first assembly seat 5, and a damper is integrated in the plurality of the return springs 8; a guide plate 9 is provided on the side of the plurality of the return springs 8 away from the first guide block.
[0026] It should be noted that since traditional tow cable arrangements are often difficult to adapt to complex and changeable working conditions, the tow cable 7 is prone to wear, breakage, or even falling off during use, seriously affecting the normal operation and operational safety of the bucket wheel excavator. This solution ensures the accuracy and stability of the operation of the tow cable 7 through the smooth sliding of the guide block 4 and the guide ropeway 3, and the stable guidance of the pulling head 12 by the guide groove 18, thereby avoiding wear caused by path deviation; secondly, the reset spring 8 built into the fastener can respond quickly when the tow cable 7 encounters external impact, effectively disperse the impact energy, protect the tow cable 7 from damage, extend the service life and improve the safety of the system; finally, the design avoids direct contact between the tow cable 7 and the ground, reduces friction and wear, and further enhances the durability and reliability of the system.
[0027] Specifically, in this embodiment, the solution mainly includes a mounting base 1; the mounting base 1 is firmly connected to the bucket wheel excavator through embedded bolts, serving as a solid foundation for the towline 7 system; then, one end of the towline 7 is firmly connected to the pulling head 12 to ensure smooth power transmission; then, the towline 7 is passed through and placed in the gaps reserved between the first assembly base 5 and the second assembly base 6. This design ensures the flexibility of the towline 7 and prevents unnecessary friction.
[0028] As the bucket wheel excavator starts and operates, the towline 7 moves accordingly, meeting the needs of the bucket wheel excavator under different working conditions. During this process, the guide block 4 in the guide mechanism slides smoothly along the guide ropeway 3, providing continuous and stable support and guidance for the towline 7, ensuring the stability of the towline 7 during complex movements and greatly reducing the risk of wear caused by shaking.
[0029] When the towline 7 is subjected to external impact or sudden changes in force, the return spring 8 in the fastener quickly absorbs and disperses the impact energy, effectively preventing the towline 7 from being damaged by the sudden force. At the same time, the built-in damper further reduces vibration, allowing the towline 7 to smoothly transition to a new state, avoiding potential damage caused by increased vibration.
[0030] In addition, the coordination between the guide plate 9 and the guide ropeway 3 is also an important factor in ensuring the safe operation of the towline 7; together they constitute a precise guiding system, ensuring that the towline 7 always moves along the predetermined path during movement, effectively preventing wear or damage that may be caused by deviation from the path.
[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a transmission cavity is provided in the mounting seat 1, and a screw rod 10 is rotatably engaged in the transmission cavity. A connecting block 11 is threadedly engaged on the screw rod 10, and the connecting block 11 slides with the transmission cavity. The connecting block 11 extends to the external position of the mounting seat 1 and is provided with a pulling head 12, and a fixing clamp 13 is provided on the pulling head 12.
[0032] In this embodiment, when the tension or position of the tow cable 7 needs to be adjusted, the tow cable 7 is firmly clamped on the pulling head 12 by using the fixing clamp 13 to prevent it from loosening or falling off; then, the screw rod 10 is driven to rotate by the servo motor 14; the rotation of the screw rod 10 drives the connecting block 11 to slide in the transmission cavity, thereby pushing the pulling head 12 to move; the movement of the pulling head 12 will drive the fixing clamp 13 and the tow cable 7 to move together, thereby realizing the adjustment of the position of the tow cable 7; during the adjustment process, it can be judged whether the desired adjustment effect is achieved by observing the tension or position changes of the tow cable 7.
[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a servo motor 14 is provided on the outer side wall of the mounting seat 1 , and the output end of the servo motor 14 is fixedly connected to the end key of the screw rod 10 .
[0034] In this embodiment, the servo motor 14 will accurately control the rotation angle and speed of its output end, thereby driving the screw rod 10 to rotate. As the screw rod 10 rotates, the connecting block 11 threadedly engaged with it will move linearly in the transmission cavity, making the adjustment process of the tow cable 7 smoother and more accurate.
[0035] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the cross sections of the guide plate 9 and the second assembly seat 6 are both arc-shaped.
[0036] In this embodiment, when the bucket wheel excavator moves, the tow cable 7 moves therewith; during this process, the arc-shaped guide plate 9 provides a smooth transition path for the tow cable 7, so that the tow cable 7 can smoothly pass through the gap from the first assembly seat 5 into the second assembly seat 6; at the same time, the arc-shaped second assembly seat 6 further supports and guides the tow cable 7 to ensure that it moves along the predetermined path; when the tow cable 7 is subjected to external force, such as sudden acceleration or deceleration of the bucket wheel excavator, the arc-shaped guide plate 9 and the second assembly seat 6 can better disperse and absorb the impact energy, reducing damage to the tow cable 7; in addition, the combined action of the return spring 8 and the damper also provides additional buffering and protection for the tow cable 7, so that the tow cable 7 can smoothly transition to a new state.
[0037] In a further preferred embodiment of the present invention, Figure 6 As shown, a group of connecting frames 15 are symmetrically provided on the inner wall of the first assembly seat 5 , and two limiting rollers 16 are rotatably fitted in the two connecting frames 15 , and arc grooves 17 are provided in the middle of the two limiting rollers 16 .
[0038] In this embodiment, the main function of the limiting roller 16 is to limit the moving trajectory of the tow cable 7, preventing the tow cable 7 from deviating from the predetermined path or causing unnecessary friction with other components during movement. The arc-shaped groove 17 is designed to fit closely to the contour of the tow cable 7. This design reduces the contact area between the tow cable 7 and the limiting roller 16, thereby reducing friction and wear. At the same time, the arc-shaped groove 17 can also ensure that the tow cable 7 maintains a stable posture during movement, preventing it from twisting or deformation due to uneven force.
[0039] In a further preferred embodiment of the present invention, Figure 4 As shown, a guide groove 18 for the pulling head 12 to slide is provided at the bottom of the mounting base 1 .
[0040] In this embodiment, the guide groove 18 provides a stable and smooth sliding path for the pulling head 12. When the bucket wheel moves, the pulling head 12 will move along the guide groove 18, ensuring that the towline 7 can move in the predetermined direction and path, avoiding wear or damage caused by deviation from the path.
[0041] Working principle: First, the mounting base 1 is firmly connected to the bucket wheel excavator through embedded bolts; this step ensures that the entire towline 7 system can move stably with the movement of the bucket wheel excavator; then, one end of the towline 7 is firmly connected to the pulling head 12 through the fixing clamp 13, which is the starting point of power transmission; the design of the pulling head 12 enables the towline 7 to smoothly transmit power or signals to meet the operation requirements of the bucket wheel excavator; then, the towline 7 is passed through and placed in the gaps reserved between the first assembly base 5 and the second assembly base 6; this layout ensures the flexibility of the towline 7, allowing it to move freely when the bucket wheel excavator is in motion, and effectively prevents unnecessary friction caused by the towline 7 being dragged, thereby extending the service life of the towline 7;
[0042] During the startup and operation of the bucket wheel excavator, the towline 7 moves accordingly, flexibly responding to various working conditions. When the tension or position of the towline 7 needs to be adjusted, the servo motor 14 accurately controls the rotation angle and speed of its output end according to the control signal, driving the screw 10 to rotate. The rotation of the screw 10 drives the connecting block 11, which is threadedly engaged with it, to move linearly in the transmission cavity, thereby pushing the pulling head 12 to move. The movement of the pulling head 12 drives the fixing clamp 13 and the towline 7 to move together, thereby achieving precise adjustment of the position of the towline 7. During the adjustment process, the change in the tension or position of the towline 7 can be observed to determine whether the desired adjustment effect has been achieved.
[0043] At this time, the guide block 4 in the guide mechanism slides smoothly along the guide ropeway 3, providing continuous and stable support and guidance for the towline 7. At the same time, the guide groove 18 at the bottom of the mounting base 1 also provides a stable and smooth sliding path for the pulling head 12, ensuring that the towline 7 can move in the predetermined direction and path, avoiding wear or damage caused by deviation from the path.
[0044] When the towline 7 is subjected to external impact or sudden changes in force, the return spring 8 in the fastener responds quickly, absorbing and dissipating the impact energy, effectively preventing the towline 7 from being damaged by the sudden force. The built-in damper further reduces vibration, allowing the towline 7 to smoothly transition to a new state and protecting its internal structure from damage.
[0045] In addition, the precise coordination between the guide plate 9 and the guide ropeway 3 is also an important factor in ensuring the safe operation of the towline 7; together they form an efficient guiding system, ensuring that the towline 7 always follows the predetermined path during movement, effectively preventing the risks that may arise from deviation from the path.
[0046] It is particularly noteworthy that the limiting rollers 16 in the first assembly seat 5 and the second assembly seat 6 closely fit the contour of the tow cable 7 through the arc-shaped grooves 17 thereon, thereby limiting the movement trajectory of the tow cable 7 and reducing friction and wear; at the same time, the arc-shaped guide plate 9 and the second assembly seat 6 also provide better support and guidance effects for the tow cable 7, ensuring the smooth operation of the tow cable 7 under complex working conditions such as acceleration or deceleration of the bucket wheel excavator.
