Description

Technical Field

[0001] This application relates to the technical field of material conveying equipment, and in particular to a wire rope support device for a hydraulic winch tensioning system. Background Technology

[0002] In the operating system of a conveyor belt machine, the tensioning system is a crucial component ensuring its stable operation. Currently, conveyor belt tensioning methods include vertical counterweight tensioning, cart-type counterweight tensioning, and cart-type hydraulic winch tensioning. Vertical counterweight tensioning and cart-type counterweight tensioning can achieve the belt tensioning function to a certain extent, but they have significant limitations. These two tensioning methods are highly dependent on space height, requiring a large space to meet the tensioning stroke requirements.

[0003] The car-type hydraulic winch tensioning system utilizes a redirecting sheave to achieve multiple windings, reducing the tension on the wire rope. By employing a hydraulic winch to absorb elongation, it combines space economy with tension stability, making it suitable for long-distance conveyor belts. Therefore, it is widely used in material yard conveyor belts or ultra-long-distance conveyor belts. The car-type hydraulic winch tensioning system saves space and reduces equipment installation costs while ensuring sufficient tension. It operates smoothly, reducing equipment vibration caused by instability in the tensioning system. Furthermore, installation and maintenance are relatively simple, improving equipment efficiency.

[0004] In the tensioning system of the car-type hydraulic winch, one end of the steel wire rope is connected to the hydraulic winch, and the other end of the steel wire rope is connected to the tail of the tensioning car. The tensioning roller of the tensioning car is connected to the conveyor belt. The hydraulic winch maintains the tension of the steel wire rope by winding and unwinding. When the tension of the conveyor belt changes, the tensioning car moves on the tensioning car track to adjust the tension of the conveyor belt accordingly, so that it is in dynamic equilibrium.

[0005] However, hydraulic winches respond relatively slowly to changes in belt tension. When tension changes occur on the belt due to the loading or unloading of heavy objects, the delayed response of the hydraulic winch can cause the tensioning wire rope to loosen. Once the wire rope loosens, it may come out of the groove of the redirecting sheave or the groove on the winch drum, resulting in tension failure, preventing the belt conveyor from operating normally, and potentially causing serious safety accidents. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a wire rope support device for a hydraulic winch tensioning system.

[0007] This application provides a wire rope support device for a hydraulic winch tensioning system, which adopts the following technical solution:

[0008] A wire rope support device for a hydraulic winch tensioning system includes a rope support frame and a rope support roller. The rope support frame is slidably mounted on the tensioning vehicle's travel track, and the rope support roller is rotatably mounted on the rope support frame, with the rope support roller located below the wire rope.

[0009] By adopting the above technical solution, when the wire rope becomes slack and sags, the rope support roller located below the wire rope supports the slack wire rope, preventing the wire rope from deviating excessively from the predetermined running trajectory. At the same time, the rotating connection design of the rope support roller effectively reduces the rolling friction loss of the wire rope during the tensioning process. Combined with the sliding characteristics of the rope support frame along the tensioning vehicle's track, it ensures the uniformity of tension and the guiding stability of the wire rope during dynamic operation, effectively solving the problem of lag in response after the wire rope becomes slack.

[0010] Preferably, the rope support frame includes an upper support, a lower support, and a connecting rod. The upper support and the lower support are fixedly connected by the connecting rod. The connecting rod is provided with a reinforcing rod, one end of which is connected to the connecting rod and the other end of which is connected to the upper support.

[0011] By adopting the above technical solution, the setting of the reinforcing rod effectively enhances the overall rigidity and structural strength of the rope support frame. By connecting the connecting rod with the upper support in a triangular support manner, the deformation of the device when subjected to the tension of the wire rope is significantly reduced, ensuring that the rope support roller and the pulley maintain a stable spatial position relationship during the dynamic tensioning process, thereby improving the reliability of the tensioning system.

[0012] Preferably, the rope support frame is connected to a rotating shaft, and the wire rope is provided with guide rollers on both sides, the guide rollers being rotatably connected to the rope support frame via the rotating shaft.

[0013] By adopting the above technical solution, the retaining roller on the lower support effectively restricts the lateral displacement of the rope support roller, preventing the wire rope from shifting laterally or derailing during the tensioning process, thus improving the safety and stability of the system operation. The retaining roller structure connected by the rotating shaft allows a certain degree of rotational freedom while maintaining the constraint on the wire rope, thereby reducing the frictional loss between the retaining roller and the wire rope and improving the overall performance and reliability of the tensioning system.

[0014] Preferably, the rope roller and the stop roller are made of polyurethane.

[0015] By adopting the above technical solutions, the elasticity and wear resistance of polyurethane material effectively reduce the mechanical wear of the wire rope during the tensioning process. The oil resistance and corrosion resistance of polyurethane material further improve the reliability of the device in humid or dusty environments, ensuring long-term stable operation and optimizing the overall performance and economy of the hydraulic winch tensioning system.

[0016] Preferably, the rope roller is detachably connected by screws, and the guide roller is detachably connected by a rotating shaft.

[0017] By adopting the above technical solutions, the detachable connection design significantly improves the maintenance convenience and structural flexibility of the device, while adapting to the roller specification adjustment needs under different working conditions, effectively shortening the maintenance cycle and downtime, and reducing operation and maintenance costs.

[0018] Preferably, the upper support is provided with a chain, one end of which is attached to the upper support and the other end is connected to the tensioning vehicle.

[0019] By adopting the above technical solution, the chain on the upper support is connected to the tensioning vehicle through buckles, ensuring that the tensioning system maintains uniform tension and consistent wire rope direction during dynamic operation. The flexible connection characteristics of the chain can buffer instantaneous impact loads and reduce the impact of mechanical vibration on the system.

[0020] Preferably, multiple wire rope support devices are arranged sequentially along the tensioning vehicle's travel track, and adjacent wire rope support devices are connected by the chain.

[0021] By adopting the above technical solution, when the tensioning car's stroke exceeds the chain link threshold of a single rope-supporting device, multiple rope-supporting devices arranged sequentially along the track form a segmented support system. This effectively solves the limitation that a single wire rope-supporting device cannot fully support the slack wire rope during the long stroke of the tensioning car, thus optimizing the operational stability and reliability of the tensioning car under long stroke conditions.

[0022] Preferably, the upper support is provided with two first fixing members and one second fixing member. The two first fixing members are respectively connected to both ends of the upper support. The first fixing members are equipped with pulleys, which are deployed on the tensioning trolley travel track. One end of the second fixing member is connected to one end of the upper support, and the other end of the second fixing member extends above the tensioning trolley travel track. A locking device is installed at the end of the second fixing member away from the upper support. The locking device is used to lock the rope support frame onto the tensioning trolley travel track.

[0023] By adopting the above technical solution, the pulleys at both ends of the upper support form a rolling support structure, ensuring that the wire rope support device can roll stably on the tensioning vehicle's travel track. The design of the second fixing component and the locking device provides additional guiding constraints for the support frame, preventing lateral displacement of the device while maintaining sliding flexibility, ensuring that the wire rope always runs along the center line of the track, enhancing the guiding accuracy and stability of the tensioning system. At the same time, the locking device fixes the wire rope support device, which can establish a stable support point.

[0024] Preferably, the locking device includes a mounting block, a first clamping arm, a second clamping arm, an adjusting screw, a handle, and an adjusting block. The first clamping arm and the second clamping arm are located on both sides of the mounting block, and the adjusting block is located on the side of the second clamping arm away from the mounting block. The adjusting screw passes through the first clamping arm, the mounting block, and the second clamping arm. The adjusting screw, the first clamping arm, and the second clamping arm are threaded together, and the handle is fixed on the adjusting block.

[0025] By adopting the above technical solution, the locking device achieves rapid positioning and locking of the rope support frame and the tensioning carriage track. The rotation operation of the handle can conveniently control the opening and closing of the first clamp arm and the second clamp arm, improving the device's anti-slip capability during dynamic tensioning.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the wire rope becomes slack and sags, the rope support roller located below the wire rope supports the slack wire rope, preventing the wire rope from deviating excessively from the predetermined running trajectory. At the same time, the rotating connection design of the rope support roller effectively reduces the rolling friction loss of the wire rope during the tensioning process. Combined with the sliding characteristics of the entire rope support frame along the tensioning vehicle's travel track, it ensures the uniformity of tension and guiding stability of the wire rope during dynamic operation, effectively solving the problem of lag response after the wire rope becomes slack.

[0028] 2. The reinforcing rod effectively enhances the overall rigidity and structural strength of the rope support frame. By connecting the connecting rod to the upper support in a triangular support manner, the deformation of the device when subjected to wire rope tension is significantly reduced, ensuring that the rope support roller and pulley maintain a stable spatial position relationship during dynamic tensioning, thereby improving the reliability of the tensioning system.

[0029] 3. The retaining rollers on the lower support effectively limit the lateral displacement of the rope support rollers, preventing the wire rope from shifting laterally or derailing during tensioning, thus improving the safety and stability of the system operation. The retaining roller structure connected to the rotating shaft allows a certain degree of rotational freedom while maintaining the constraint on the wire rope, thereby reducing the frictional loss between the retaining rollers and the wire rope and improving the overall performance and reliability of the tensioning system.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0038] This application discloses a wire rope support device for a hydraulic winch tensioning system.

[0039] Reference Figure 1 and Figure 2 A wire rope support device for a hydraulic winch tensioning system includes a support frame 1 and a support roller 2. The support frame 1 is slidably mounted on a tensioning carriage travel track 04 and is connected to the tensioning carriage 02. The support roller 2 is mounted on the support frame 1. The wire rope 03 is output from the output end of the hydraulic winch 00 and wound between the tensioning carriage 02 and the redirecting sheave 01. The support roller 2 is located below the wire rope 03. When the hydraulic winch 00 has a delayed response, causing the wire rope 03 to slack and sag, the support roller 2 supports the slack wire rope 03, preventing the wire rope 03 from deviating excessively from the predetermined running trajectory, reducing the risk of the wire rope 03 detaching from the groove of the redirecting sheave 01 or the winch drum groove, and improving the stability of equipment operation.

[0040] Reference Figure 3 The rope support frame 1 includes an upper support 11, a lower support 12 and a connecting rod 13. The upper support 11 and the lower support 12 are rigidly connected and fixed by the connecting rod 13. A reinforcing rod 4 is provided in the middle of the connecting rod 13. One end of the reinforcing rod 4 is connected to the connecting rod 13 and the other end is connected to the upper support 11. When the device is subjected to external force, the connecting rod 13 can ensure the stability of the entire device structure.

[0041] The rope support roller 2 is rotatably mounted on the lower support 12. There is a gap between the rope support roller 2 and the lower support 12 to prevent friction between the rope support roller 2 and the lower support 12 when the wire rope 03 is slack and falling. The rope support roller 2 located below the wire rope 03 provides stable support for the wire rope 03 through contact, ensuring that the wire rope 03 does not deviate excessively from the predetermined trajectory throughout the entire stroke. When the wire rope 03 moves, the rope support roller 2 rotates accordingly to reduce sliding friction and reduce the working wear of the wire rope 03.

[0042] Reference Figure 3 and Figure 5 The lower support 12 is equipped with guide rollers 5. In this embodiment, two guide rollers 5 are preferably installed vertically on the lower support 12 via a rotating shaft 14, allowing the guide rollers 5 to rotate around the shaft. The two guide rollers 5 are located on both sides of the wire rope 03, and the top of the guide rollers 5 is higher than the position of the wire rope 03. The guide rollers 5 limit the lateral displacement of the wire rope 03, preventing excessive horizontal deviation of the wire rope 03 during movement, and continuously constrain the wire rope during the operation of the tensioning vehicle 02, keeping it on the correct running path.

[0043] Preferably, in this embodiment, the rope support roller 2 and the guide roller 5 are made of polyurethane material. Polyurethane material has good wear resistance and low coefficient of friction, which greatly extends the service life of the rope support roller 2.

[0044] The rope-supporting roller 2 is detachably connected by screws, and the guide roller 5 is detachably connected by a rotating shaft 14. The rope-supporting roller 2 and the guide roller 5 are independently installed on the rope-supporting frame 1. When a single part is damaged, there is no need to replace the whole thing. Maintenance personnel can quickly locate and replace the faulty roller, reducing reliance on professional skills, reducing the replacement frequency of the rope-supporting device, reducing maintenance costs, and improving the operating efficiency of the equipment.

[0045] Reference Figure 3 The upper support 11 has two first fixing parts 6 at both ends. The two first fixing parts 6 are welded to the lower part of both ends of the upper support 11 respectively. The first fixing part 6 is rotatably mounted with a pulley 7 at the end away from the upper support 11. The first fixing part is connected to the axis of the pulley 7. The pulley 7 is rolled on the tensioning vehicle travel track 04 to move the tow rope frame on the tensioning vehicle travel track 04.

[0046] Reference Figure 1 and Figure 2 A chain 3 is installed on the top edge of the upper bracket 11 and fixed by a buckle. The other end of the chain 3 is connected to the tensioning carriage 02. When the tensioning carriage 02 moves a long distance along the tensioning carriage travel track 04, the chain 3 of the upper bracket 11 will be tightened and move with the tensioning carriage 02.

[0047] When the tensioning stroke of the tensioning carriage 02 is short, a single wire rope support device is sufficient. If the tensioning stroke of the tensioning carriage 02 is long, multiple wire rope support devices can be used in combination, and these devices will be arranged sequentially along the tensioning carriage's travel track 04. When the belt load increases, the belt elongates, causing the tensioning carriage 02 to move away from the hydraulic winch 00. The tensioning carriage 02 then drives the wire rope support devices to move sequentially via the chain 3.

[0048] Reference Figure 3 One end of the upper support 11 is provided with a second fixing member 8, which is L-shaped. One end of the L-shaped structure of the second fixing member 8 is welded to the end of the upper support 11, and the other end extends above the tensioning vehicle travel track 04 and is equipped with a locking device 10. The locking device 10 is used to lock the rope support frame 1 onto the tensioning vehicle travel track 04 to prevent the rope support frame 1 from shifting due to vibration or tension changes, which could cause the wire rope 03 to slack.

[0049] Reference Figure 4 The locking device 10 includes a mounting block 9, a first clamping arm 101, a second clamping arm 102, an adjusting screw 103, a handle 104, and an adjusting block 105. The mounting block 9 is assembled at the end of the second fixing member 8 away from the rope support frame 1. The first clamping arm 101 and the second clamping arm 102 are located on both sides of the mounting block 9. The adjusting screw 103 passes through the first clamping arm 101, the mounting block 9, and the second clamping arm 102 in sequence. The adjusting block 105 is located on the side of the second clamping arm 102 away from the first clamping arm 101 and is threadedly engaged with the adjusting screw 103. The tensioning vehicle travel track 04 is located in the clamping structure formed by the first clamping arm 101 and the second clamping arm 102. The handle 104 is welded to the adjusting block 105. By rotating the handle 104, the position of the adjusting block 105 on the adjusting screw 103 is adjusted, so that the first clamping arm 101 and the second clamping arm 102 are closer or further apart, so as to clamp or loosen the tensioning vehicle travel track 04.

[0050] When the belt load increases, the belt elongates, causing the tensioning carriage 02 to move away from the hydraulic winch 00. The farthest rope support device is the one furthest from the tensioning carriage 02, so its position is least affected by the movement of the tensioning carriage 02. By fixing the farthest wire rope support device with the locking device 10, a stable support point can be established, ensuring that subsequent wire rope support devices can support and guide the wire rope 03 in a timely and effective manner.

[0051] The implementation principle of this application embodiment is as follows: During the assembly process of a wire rope support device for a hydraulic winch tensioning system, the required number of wire rope support devices is first determined based on the tensioning stroke of the tensioning carriage 02. The support roller 2 is installed on the support frame 1, ensuring its flexible rotation. Baffle rollers 5 are installed on both sides of the support roller 2, ensuring a gap between the baffle rollers 5 and the support roller 2, effectively restricting the wire rope 03. The locking device 10 is installed on the second fixing member 8 of the support frame 1. After the device assembly is completed, the wire rope support devices are arranged on the tensioning carriage travel track 04, and the tensioning carriage 02 is connected to each wire rope support device using a chain 3, ensuring smooth coordinated movement between the device and the tensioning carriage 02.

[0052] A wire rope support device for a hydraulic winch tensioning system operates as follows: When the hydraulic winch 00 tensioning system is activated, the hydraulic winch 00 drives the tensioning carriage 02 to move along the track via the winding wire rope 03, providing pre-tension to the conveyor belt. When the conveyor belt elongates due to increased load, the hydraulic winch 00 unwinds, and the tensioning carriage 02 moves away from the winch. The support roller 2, with its rotating connection design, continuously supports the slack section of the wire rope 03. The low-friction properties of the polyurethane material reduce rolling resistance, ensuring the wire rope 03 maintains a preset height and tension. The guide rollers 5 on both sides of the lower support 12 rotate synchronously, constraining the lateral displacement of the wire rope 03 and preventing it from dislodging from the redirecting sheave 01 or the drum groove. In long-stroke conditions, multiple support devices are arranged sequentially along the track. The first device is fixed to the starting point of the track by a locking device 10, and subsequent devices are connected by chains 3. When the tensioning carriage 02 moves, the fixed end provides a stable reference, and the moving end device achieves uniform tension transmission through the chain 3, avoiding the accumulation of slack.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
