Description

Technical Field

[0001] This utility model relates to the field of hydraulic tensioning equipment technology, and in particular to a hydraulic tensioning device based on hydraulic winch drive. Background Technology

[0002] With the continuous development of industrial production, the demand for hydraulic systems is increasing. As an important component of hydraulic systems, hydraulic tensioning devices are widely used in machinery, metallurgy, mining and other fields. Their main function is to tension ropes or strips in the system through hydraulic drive, thereby ensuring the normal operation and stable operation of the equipment. At present, hydraulic tensioning devices based on hydraulic winch drive are gradually becoming an indispensable piece of equipment in the industry due to their simple operation, stable operation and strong load capacity.

[0003] In the prior art, hydraulic tensioning devices typically use mechanical locking to connect the drum, achieving the prying and tensioning effect through threaded connections or other fixing methods. These devices rely on traditional mechanical structures, such as gears, nuts, bolts, and other connecting parts, to ensure the drum is fixed. This structure provides a relatively reliable tensioning effect.

[0004] However, the traditional drum installation method has a significant problem: due to the use of threaded connections, the bolts are prone to loosening after long-term use, which leads to instability in the position of the drum during operation, thereby affecting its working efficiency and safety. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hydraulic tensioning device based on a hydraulic winch drive, which aims to improve the problem that the bolts may loosen after long-term use due to the use of threaded connections, resulting in unstable position of the drum during operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic tensioning device based on a hydraulic winch drive, comprising a drum, with rotating disks fixedly connected to both ends of the drum, a support base provided below the drum, a fixing plate fixedly connected to the upper surface of the support base, a drive motor fixedly connected to the outer wall of the fixing plate, a fixing disk fixedly connected to the output end of the drive motor, and mounting components provided on the outer walls of both rotating disks;

[0007] The installation assembly includes a second fixed disk, the outer wall of which is fixedly connected to the outer wall of the rotating disk. The inner wall of the second fixed disk has a slot, and a spring is fixedly connected to the inner wall of the second fixed disk. One end of the spring is fixedly connected to a baffle, and a locking block is fixedly connected to one side of the outer wall of the baffle. A fixed sleeve is slidably connected to the outer wall of the second fixed disk, and a rotating sleeve is fixedly connected to one end of the fixed sleeve. One end of the rotating sleeve is fixedly connected to the outer wall of the first fixed disk.

[0008] Furthermore, a connecting rod is fixedly connected to the outer wall of the fixing plate, a telescopic component is provided on the outer wall of the connecting rod, and a guide component is provided above the connecting rod.

[0009] Furthermore, the telescopic assembly includes a telescopic rod one, one side of the outer wall of the telescopic rod one is fixedly connected to the outer wall of the connecting rod one, a telescopic rod two is slidably connected to the inner wall of the telescopic rod one, a limit rod is slidably connected to the inner wall of the telescopic rod two, and a limit hole is provided inside the telescopic rod one.

[0010] Furthermore, the guide assembly includes a second fixing plate, the lower surface of which is fixedly connected to the upper surface of the second telescopic rod, and a second connecting rod is fixedly connected to one side of the outer wall of the second fixing plate, and a rotating shaft is rotatably connected to the outer wall of the second connecting rod.

[0011] Furthermore, the lower surface of the fixing plate is fixedly connected to the upper surface of the support base, which is used to support the drum.

[0012] Furthermore, the outer wall of the limiting rod is slidably connected to the inner wall of the first telescopic rod, and the limiting rod is used to limit the second telescopic rod.

[0013] Furthermore, the outer wall of the card block is slidably connected to the inner wall of the fixing sleeve, and the card block is used to fix the second disk.

[0014] Furthermore, the outer wall of the fixed disk is rotatably connected to the inner wall of the fixed plate, and the drive motor drives the fixed disk to rotate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the action of the locking block and the locking groove, when it is necessary to install or disassemble the drum, the locking block is pressed inward, and the spring is compressed so that the locking block can disengage from the locking groove, thus realizing the disassembly of the drum. During installation, the locking block is directly inserted into the locking groove. This effectively improves the problem that the traditional drum installation uses threaded connection, which is prone to loosening of screws after long-term use. It achieves the effect of quick installation and disassembly of the drum. This structural design is convenient for maintenance and repair.

[0017] 2. In this utility model, through the action of the telescopic rod and the rotating shaft, when the tensioning device is used, the rotation of the rotating shaft can guide the rope. At the same time, the height of the rotating shaft can be adjusted according to the needs, which effectively prevents the rope from deviating or crossing during the operation of the machine, guides the rope to wind neatly, and thus improves the winding efficiency.

A baffle 19 is fixedly connected to one end of the spring 20. The baffle 19 limits the range of motion and prevents damage caused by excessive movement of the components. A locking block 17 is fixedly connected to one side of the outer wall of the baffle 19. The locking block 17 can slide within a specific range. The function of the locking block 17 is to slide within the fixed disk 18, thereby adjusting and locking the position of the installed components. A fixed sleeve 16 is slidably connected to the outer wall of the fixed disk 18. A rotating sleeve 15 is fixedly connected to one end of the fixed sleeve 16. The rotating sleeve 15 is used to connect other rotating components and promote the transmission of rotational motion. One end of the rotating sleeve 15 is fixedly connected to the outer wall of the fixed disk 14. The fixed disk 14 is used to receive the power transmitted by the drive motor 1 and rotate to drive the entire device to operate.

[0025] Reference Figures 1-2 A connecting rod 6 is fixedly connected to the outer wall of the fixed plate 2. The connecting rod 6 connects the fixed plate 2 to the telescopic assembly, providing adjustable height and position settings. The telescopic assembly is located on the outer wall of the connecting rod 6, and a guide assembly is located above the connecting rod 6. The telescopic assembly includes a telescopic rod 7, one side of which is fixedly connected to the outer wall of the connecting rod 6. A telescopic rod 8 is slidably connected to the inner wall of the telescopic rod 7. The telescopic rod 8 is used to increase or decrease its length during operation to adapt to different working environments and needs. The inner wall of the telescopic rod 8 has a limit connection. Rod 9, the limiting rod 9 is used to limit the telescopic rod 8 to prevent excessive extension and contraction from damaging the components, and also to ensure the safety and stability of the equipment. The telescopic rod 7 is provided with a limiting hole 10 inside, which is used to accurately position and fix the telescopic rod 8, increasing the working stability and reliability. The guide component includes a fixing plate 11, the lower surface of which is fixedly connected to the upper surface of the telescopic rod 8, which plays a role in guiding and stabilizing the movement. A connecting rod 12 is fixedly connected to one side of the outer wall of the fixing plate 11, and a rotating shaft 13 is rotatably connected to the outer wall of the connecting rod 12.

[0026] Reference Figures 1-3The lower surface of the fixed plate 2 is fixedly connected to the upper surface of the support base 4.

The drive motor 1 drives the fixed disc 14 to rotate, thereby realizing the operation and tensioning effect of the entire hydraulic tensioning device.

[0027] Working principle: When this hydraulic tensioning device is needed, the drive motor 1 first starts working, driving the drum 5 to rotate steadily to complete the winding or unwinding of the rope. If the drum 5 needs to be replaced or repaired, simply press the locking block 17 inward. Under the compressive force of the spring 20, the fixing disc 18 will disengage from the fixing sleeve 16, thus achieving quick disassembly, improving work efficiency and reducing maintenance time. When reinstalling the drum 5, the operator only needs to gently press the locking block 17 to make it engage with the inner wall of the fixing sleeve 16, thus ensuring that the drum 5 is firmly and safely fixed in place, facilitating subsequent operations. The device provides reliable support. During normal operation, the rope is wound around the rotating shaft 13. The rotating shaft 13 not only has a good guiding function, but also effectively prevents the rope from deviating and crossing during operation, ensuring that the rope is neatly and smoothly wound on the drum 5. The height of the rotating shaft 13 can be adjusted as needed through the telescopic rod 7 and the telescopic rod 8. The operator can flexibly adjust the height of the rotating shaft 13 according to actual needs, so that the device can maintain the best working condition under different working conditions. The hydraulic tensioning device is not only easy to operate, but also adaptable to a variety of application environments, greatly improving the overall performance and practicality of the system.
