Abstract
Description
Technical Field
[0001] This invention relates to the field of cableway laying technology, specifically to a steel wire rope resistance device for laying hydrological cables. Background Technology
[0002] Hydrological cableways are used for more precise acquisition of hydrological data. They consist of tower structures erected on both banks of the river, with high-strength steel wire ropes strung between them as load-bearing cables. These cables support the weight of measuring instruments (lead weights), movable devices (gantry cranes) connecting other components, and auxiliary measuring equipment, ensuring their safe and stable suspension above the river for flow measurement operations. During cableway construction, the steel wire ropes are typically first coiled on one bank and ferried across the river using a small boat or tow rope. Then, winches or pulley systems are used to tighten the ropes. The observation and adjustment of the main cable's sag is crucial; the sag error must be controlled within the design range. Afterward, the traction system and drive and control equipment are installed. Once all installation is complete, no-load and load operation tests are conducted to check the smooth operation of each component, the accuracy of positioning, and the continuity of signals. Before use, the distance and depth measuring systems must also be calibrated on-site to ensure accurate and reliable measurement data.
[0003] Currently, when using small boats and towing ropes to ferry people across rivers, the new steel wire ropes tend to sink into the water and drag along the riverbed due to the weak tension control mechanism during deployment. This not only damages the anti-rust oil film but also easily causes the steel wire ropes to get stuck in the crevices of rocks on the riverbed. Furthermore, without tension, the steel wire ropes release a considerable length, making it difficult to tighten and secure the cableway later. Summary of the Invention
[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a steel wire rope resistance device for laying hydrological cableways. This device solves the problem that when laying steel wire ropes, due to a weak tension control mechanism, new steel wire ropes tend to sink into the water and drag along the bottom of the river. This not only damages the anti-rust oil film but also easily causes the steel wire rope to get stuck in the crevices of rocks on the riverbed. Furthermore, without tension, the steel wire rope releases a long length, making it difficult to tighten and secure the cableway steel wire rope later.
[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a wire rope resistance device for laying hydrological cableways, comprising a base frame, a track, and further comprising: A wheeled drag device is installed inside the track to support a steel wire rope. The steel wire rope is made into a curved structure by continuous winding. When the released steel wire rope passes through the wheel set of the wheeled drag device, it deforms and generates travel resistance when the steel wire rope is released, so that the steel wire rope does not fall into the water with a large arc when released. Two sets of wheeled resistance devices are installed inside the track, which allows the wire rope to generate two curved deformation areas, thereby increasing the resistance of the wheeled resistance device to the wire rope during wire laying. An adjustment mechanism is installed on the track and is used to simultaneously adjust the distance between the two sets of wheeled resistance devices, thereby changing the wrap angle between the wire rope and the wheel set to adjust the resistance value of the resistance device. The guiding mechanism is located at the upper end of the bottom frame.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a steel wire rope resistance device for laying hydrological cableways, which has the following beneficial effects: 1. The wheeled resistance device designed in this technical solution is installed inside the track to support the steel wire rope. Through continuous winding, the steel wire rope is made into a curved structure. When the released steel wire rope passes through the wheel set of the wheeled resistance device, it will deform and generate travel resistance when the steel wire rope is released. This prevents the steel wire rope from falling into the water with a large arc when released. At the same time, the resistance of the resistance device can be adjusted according to the diameter of the steel wire rope. Furthermore, when the spacing between the wheel sets is at its maximum, it is also convenient to wrap the new steel wire rope around the wheel set for wiring.
[0016] 2. During operation, the drive motor is started to rotate the sprocket and chain, which in turn drives the two shafts to rotate. When the shafts rotate, they drive the first bevel gear and the second bevel gear to rotate. The rotation of the second bevel gear drives the double-acting screw to rotate, which drives the internal threaded tube to move the first slide. The movement of the first slide drives the top block to push the second slide to move. In this way, the movement of the first and second slides can drive the first-stage and second-stage adjusting wheels to move closer to the fixed wheel. This allows the angle of wrap between the wire rope and the wheel assembly to be adjusted, thereby achieving the purpose of adjusting the resistance of the wheel-type resistance device.
[0017] 3. The guiding mechanism in this technical solution, when the wire rope has a large unwinding length and its weight exceeds the resistance value of the wheel-type resistance device, can drive the gear to rotate the internal gear ring by starting the reduction motor. The rotation of the internal gear ring drives the disc and the reel to select. At this time, the wire rope will be wrapped between the two reels, which can further form a curved deformation section of the wire rope, further increasing the resistance of the wire rope. At the same time, the rotation can continue to make the wire rope continue to be wrapped, thus forming a winding point. Pulling the wire rope in the opposite direction can tighten the wire rope to achieve the purpose of pre-tightening the wire rope, which is convenient for subsequent fixing and cutting of the wire rope.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example: This invention provides a steel wire rope resistance device for laying hydrological cableways. It is used to generate resistance to the new steel wire rope during the laying of new hydrological cableways and the replacement of existing cableways. The resistance is generated by the deformation of the steel wire rope on the resistance device. This deformation allows the steel wire rope to overcome its own weight during release, preventing it from sinking excessively when crossing a river. This prevents the new steel wire rope from sinking into the water, avoiding it from getting stuck in crevices or other debris at the bottom of the river, and also preventing it from being soaked in water, which would necessitate rust prevention treatment after the cableway is laid.
[0022] See attached document Figure 1-8The specific technical solution includes a base frame 1 and a track 2. The key component is the wheel-type resistance device designed in this solution. The wheel-type resistance device comprises a fixed wheel 9, a primary adjusting wheel 7, and a secondary adjusting wheel 8. These three components form the wheel assembly of the wheel-type resistance device. Two sets of wheel-type resistance devices are installed within the track 2, allowing the wire rope to generate two curved deformation regions. This increases the resistance of the wheel-type resistance device on the wire rope during release. Using the wheel assembly composed of the fixed wheel 9, primary adjusting wheel 7, and secondary adjusting wheel 8, the wire rope can be confined into two curved segments within a certain arc range during release. Since the wire rope naturally generates resistance when deformed, within the two continuous curved deformation regions, the wire rope, under a certain external force... The resistance is released only when pulled. A central shaft is located at the center of the fixed wheel 9, and this central shaft is rotatably connected to the track 2 via ball bearings. A slotted hole is formed in the side wall of the track 2, within which a first support shaft and a second support shaft are installed. The first-stage adjusting wheel 7 is coaxially fixed to the shaft wall of the first support shaft, and the second-stage adjusting wheel 8 is fixed to the shaft wall of the second support shaft. The first and second support shafts are connected to the adjusting mechanism, allowing the first-stage adjusting wheel 7 and the second-stage adjusting wheel 8 to move closer to the fixed wheel 9, thereby changing the distance between the wheel sets of the wheel-type resistance device. The adjusting mechanism is mounted on the track 2 and is used to simultaneously adjust the distance between the wheel sets of the two wheel-type resistance devices, thereby changing the wrap angle between the wire rope and the wheel sets to adjust the resistance value of the resistance device. Figure 7 As shown, when the distance between the first-stage adjusting wheel 7 and the second-stage adjusting wheel 8 of the two sets of wheels narrows and approaches the fixed wheel 9, the wrap angle of the wire rope on the wheels increases. Therefore, if the wire rope is to move forward, the pulling force must be increased, which can then be used to adjust the resistance value of the resistance device. Specifically, the adjustment mechanism includes two first slides 20 and two second slides 21. The first support shaft is rotatably connected between the two first slides 20 via ball bearings, and the second support shaft is rotatably connected between the two second slides 21 via ball bearings. Two bidirectional lead screws 19 are provided on opposite sides of the track 2. Two internally threaded tubes 16 are threadedly connected to the rod walls of the two bidirectional lead screws 19. A bracket is fixedly connected to the tube wall of the internally threaded tube 16, and the bracket is fixed to one side of the first slide 20. A top block 32 is fixedly connected to one side of the first slide block 20. The top block 32 is used to push the second slide block 21 to move and limit the distance between it and the first slide block 20. Two slide rails 24 are fixedly connected to the side wall of the track 2. Slide grooves that cooperate with the slide rails 24 are opened on the opposite sides of the first slide block 20 and the second slide block 21. A drive mechanism for driving the bidirectional lead screw 19 is fixedly connected to the upper end of the track 2. The drive mechanism is used to drive the two bidirectional lead screws 19 to rotate simultaneously to provide driving force to both sides of the first slide block 20. The drive mechanism includes a support 6 fixed to the upper end of the track 2. Two rotating shafts 29 are rotatably connected to the support 6 via rolling bearings. A first bevel gear 18 is fixedly connected to the lower end of each of the two rotating shafts 29. A second bevel gear 17 meshes with one side of the first bevel gear 18. The second bevel gear 17 is coaxially fixed to the wall of the double-acting lead screw 19. A chain 28 is provided on one side of the support 6. Two sprockets 27 are wound around the chain 28. The two sprockets 27 are fixedly connected to the upper ends of the two rotating shafts 29 respectively. A drive motor 5 is fixedly connected to the upper end of the support 6. The output end of the drive motor 5 is fixedly connected to the upper end of one of the sprockets 27.
[0023] A guide rod 23 is fixedly connected to one side of the second slide 21. A spring 22 is sleeved on the wall of the guide rod 23. A support block 25 is fixedly connected to one side of the track 2. One side of the support block 25 is sleeved on the wall of the guide rod 23 through a guide hole. The two ends of the spring 22 contact the support block 25 and the second slide 21 respectively. A travel limit block 30 and a positioning block 31 are fixedly connected to the track 2 to limit the movement of the second slide 21. The second slide 21 is located between the travel limit block 30 and the positioning block 31.
[0024] In summary, the wheeled resistance device is installed inside track 2 to support the steel wire rope. Through continuous winding, the steel wire rope is made into a curved structure, so that the released steel wire rope deforms as it passes through the wheel set of the wheeled resistance device, generating travel resistance when the steel wire rope is released. This prevents the steel wire rope from falling into the water with a large arc when released. At the same time, the resistance of the resistance device can be adjusted according to the diameter of the steel wire rope, and it is also convenient to wrap new steel wire ropes around the wheel set when the spacing of the wheel set is at its maximum. During operation, the drive motor 5 is started to drive the sprocket 27 and chain 28 to rotate, which in turn drives the two rotating shafts 29 to rotate. When the rotating shafts rotate, they drive the first bevel gear 18 and the second bevel gear 17 to rotate. The rotation of the second bevel gear 17 drives the bidirectional lead screw 19 to rotate, which drives the internal threaded tube 16 to move the first slide 20. The movement of the first slide 20 drives the top block 32 to push the second slide 21 to move. In this way, the movement of the first slide 20 and the second slide 21 can drive the first-stage adjusting wheel 7 and the second-stage adjusting wheel 8 to move closer to the fixed wheel 9. This can adjust the wrap angle between the wire rope and the wheel assembly, thereby achieving the purpose of adjusting the resistance of the wheeled resistance device.
[0025] Compared to the traditional mechanical clamping and roller resistance method, this technical solution does not affect the spiral winding structure of the wire rope and will not cause stall failure. At the same time, the release speed is controlled by the winding speed of the winch equipment on the opposite bank, so that the wire rope will not enter the water during the laying of the cableway and always maintains a certain tension, which is convenient for subsequent tightening of the wire rope to achieve the cableway tension.
[0026] To further improve the stability during wire laying and to assist in tightening the wire rope, this technical solution also includes a guide mechanism. The guide mechanism is located at the upper end of the bottom frame 1 to limit the wire rope laying end. At the same time, it can reverse the winding of the wire rope after laying to reduce the sag of the wire rope and pre-tighten the laid wire rope cableway.
[0027] The specific technical solution includes a support base 11, which is fixed on the track 2. The support base 11 is rotatably connected to two horizontal shafts via ball bearings. A disc 13 is fixedly connected to one end of each horizontal shaft. Two scrolls 12 are fixedly connected between the two discs 13, and rotatable bushings 34 are fitted onto the shaft walls of the scrolls 12. A reduction motor 10 is fixedly connected to one side of the support base 11. The output end of the reduction motor 10 passes through the side wall of the support base 11 and is fixedly connected to a gear 33. An internal gear ring 14 meshes with one side of the gear 33. 4. The two discs 13 are coaxially fixed on one side of one of the discs 13. The edges of the two discs 13 are provided with guide parts. The guide parts are an integrally formed ring-shaped folded edge structure at the edge of the disc 13 to reduce friction damage to the wire rope. One side of the support base 11 is rotatably connected to the directional wheel 26 through the bearing seat. The bottom plate of the support base 11 has a notch for the wire rope to pass through. Two limiting rollers 15 are provided on the upper end of the track 2 away from the directional wheel 26. The two limiting rollers 15 are rotatably connected to the upper end of the track 2 through the bearing seat, and the axis of the limiting rollers 15 is parallel to the track 2.
[0028] like Figures 5-9 As shown, during use, the wire rope needs to pass between two reels 12. The bushing 34 can reduce friction on the wire rope and support the wire rope during unwinding. When the unwinding length of the wire rope is large and the weight exceeds the resistance value of the wheel-type resistance device, the gear 33 can be driven by starting the reduction motor 10 to rotate the internal gear ring 14. The rotation of the internal gear ring 14 drives the disc 13 and the reel 12 to select each other. At this time, the wire rope will be wrapped between the two reels 12, so that the wire rope can further form a curved deformation section, further increasing the resistance of the wire rope. At the same time, the rotation can continue to make the wire rope continue to be wrapped, thus forming a winding point. Pulling the wire rope in the opposite direction can tighten the wire rope to achieve the purpose of pre-tightening the wire rope, which is convenient for subsequent fixing and cutting of the wire rope.
[0029] The upper end of the bottom frame 1 is fixedly connected to the wire feeding frame 3, and the wire feeding shaft 4 is installed on the wire feeding frame 3. The lower end of the bottom frame 1 is fixedly connected to the pad, and the pad is provided with fixing holes. The motor used in this resistance device can be powered by the power supply of the hydrological cableway base station, or by a mobile power supply, generator or other equipment. This will not be elaborated on here.
[0030] like Figure 9As shown, this resistance device can be fixed to the base of the hydrological cableway tower using expansion bolts. A winch is installed on the tower base on the opposite bank to pull the steel wire rope across the river until the laying is completed. When laying a new cableway, the winch's traction rope is released to a sufficient length, first passing through the river channel and then connecting to the free end of the new wire rope. Then, the traction force of the winch, combined with the resistance of the resistance device, can be used to maintain a certain tension in the new wire rope, preventing it from sagging into the water and ensuring its rust resistance.
[0031] When replacing an old cableway, the free end of the old wire rope is connected to the free end of the new wire rope, and the traction rope of the winch is connected to the other end of the old rope. At this time, the replacement and laying of the hydrological cableway can be completed by using the winch in conjunction with the resistance device.
