Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically to a heavy-duty saddle device for the top of a cable tower. Background Technology

[0002] In recent years, the main span of large bridges has been continuously increased, and the scale of offshore wind power equipment installation has continued to expand. Cable cranes are widely used in engineering construction. Cable cranes are composed of towers, cables, lifting devices, and pylons. Among them, the pylons are key supports and bear the heavy responsibility of maintaining the stability of the overall structure. The heavy-duty saddle at the top of the pylon not only guides the direction of the cables and ensures the effective transmission of force during lifting, but also bears a huge lifting weight, which directly determines the safety performance and working efficiency of the cable crane. The heavy-duty saddle is usually connected to the cables through a specific cable groove. The design of the cable groove fully considers the shape and stress characteristics of the cables to ensure that the two fit tightly together.

[0003] However, the existing technology has the following problems:

[0004] When constructing in areas with large temperature differences between day and night, the cables expand and contract frequently due to thermal changes. Since the thermal expansion coefficients of the cable and saddle materials are different, their expansion and contraction amounts also differ under the same temperature changes. Because the cable exerts a large downward pressure on the saddle, the cable will generate a large lateral compressive stress on the saddle during thermal expansion and contraction, which will aggravate the wear between the cable and the saddle, thereby shortening the service life of the cable and the saddle.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0017] 1. The heavy-duty saddle body device on the top of the cable tower, through the setting of the telescopic compensation component, enables multiple sliding pads to expand and contract synchronously when the cable expands and contracts. The multiple sliding pads assist the cable in expanding and contracting through their own movement, thereby reducing the lateral compressive stress generated on the sliding pads during cable expansion and contraction, achieving the effect of telescopic compensation, avoiding local stress concentration in the cable and aggravating wear, and thus extending the service life of the cable and saddle. Through the setting of multiple pressure blocks, the pressure blocks can press the cable tightly, improving the stability between the cable and the sliding pads. Through the cooperation of the second gear and the second tooth block, the pressure blocks can adaptively clamp according to the thermal expansion and contraction of the cable, avoiding deformation of the pressure blocks and sliding pads when the cable expands and squeezes the pressure blocks.

[0018] 2. The heavy-duty saddle body device on the top of the cable tower, through the setting of the lubrication components, allows the oil tanks on both sides of the sliding pad to automatically inject grease into the oil groove inside the sliding pad when it moves. This causes multiple oil holes at the bottom of the sliding pad to squeeze out the grease, lubricating the sliding pad and the liner, thereby reducing the friction when the sliding pad moves and extending the service life of the sliding pad. Through the setting of multiple disturbance rods, the disturbance rods can agitate the grease in the oil tank by moving left and right, thereby maintaining the uniformity of the grease and avoiding uneven grease distribution, which would affect the performance.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] Example 1

[0035] Please see Figure 1 - Figure 8A heavy-duty saddle body device for cable tower tops includes a saddle 1 with a cable groove 2 and two side grooves 3 inside the saddle 1, located on opposite sides of the cable groove 2. It also includes a telescoping compensation component 4 for compensating for cable expansion and contraction due to thermal expansion and contraction. The telescoping compensation component 4 includes a liner 41 installed inside the cable groove 2, with multiple sliding pads 42 slidably connected to the liner 41. Two pin holes are located on the left side of each sliding pad 42, and two pins are located on the right side of each sliding pad 42. The two pin holes of the adjacent sliding pad 42 are slidably connected. Multiple sliding pads 42 are connected side by side through the cooperation of the pin and the pin hole to form a multi-section telescopic structure. The top surface of the pad 41 is smooth. Multiple sliding pads 42 can slide on the pad 41 to a certain extent. The cable is attached to the multiple sliding pads 42. When the cable retracts, it drives the multiple sliding pads 42 to slide on the pad 41. The multi-section telescopic structure of the multiple sliding pads 42 slides on the pad 41 in combination with the thermal expansion and contraction of the cable, reducing the friction generated when the cable retracts.

[0036] Furthermore, first toothed blocks 43 are connected to both sides of the sliding pad 42, and the two first toothed blocks 43 are located in the two side grooves 3 respectively. Telescopic columns 44 are slidably connected to the outer walls of both sides of the saddle 1 via multiple brackets. Two pry bars 45 are rotatably mounted on the right end of the saddle 1 via brackets. Arc-shaped racks 46 are slidably connected in the two side grooves 3, and multiple first gears 47 are rotatably mounted in the side grooves 3. The left end of the telescopic column 44 is fixed to the saddle 1 by a fastener. The tops of the two pry bars 45 are slidably hinged to the right ends of the two telescopic columns 44 respectively, and the bottoms of the two pry bars 45 are respectively... Hinged to the right ends of the two arc-shaped racks 46, the right end of the telescopic column 44 moves using a lever principle, which drives the arc-shaped racks 46 to move in the opposite direction via the pry bar 45. A through hole is provided between the side groove 3 and the cable groove 2. The connection between the first tooth block 43 and the sliding pad 42 is located in the through hole of the side groove 3. The first gear 47 is provided with an outer gear and an inner gear. The first gear 47 is a double-layer gear. The inner gears of multiple first gears 47 mesh with multiple first tooth blocks 43 respectively. The outer gears of multiple first gears 47 in the same side groove 3 all mesh with the arc-shaped racks 46. Multiple first gears 47 The outer gears are all the same size. The size and number of teeth of the inner gears of the multiple first gears 47 within the same side groove 3 increase sequentially from left to right. The outer gear of the first gear 47 meshes with the arc-shaped rack 46, and the inner gear of the first gear 47 meshes with the first tooth block 43. Therefore, when the arc-shaped rack 46 moves the same distance, the leftmost sliding pad 42 moves the least left and right. The movement amplitude of the multiple sliding pads 42 increases sequentially from left to right. During cable extension and retraction, the multiple sliding pads 42 can extend and retract synchronously through cooperation. The sliding pads 42 are passively subjected to the frictional force during cable extension and retraction. The sliding mechanism is transformed into active sliding of the sliding pad 42 to cooperate with the cable extension and contraction, thereby reducing the lateral compressive stress on the sliding pad 42 during cable extension and contraction, achieving the effect of extension and contraction compensation. Through the setting of the extension and contraction compensation component 4, multiple sliding pads 42 can cooperate to extend and contract synchronously during cable extension and contraction. Multiple sliding pads 42 assist the cable in extension and contraction through their own movement, thereby reducing the lateral compressive stress on the sliding pad 42 during cable extension and contraction, achieving the effect of extension and contraction compensation, avoiding local stress concentration in the cable and aggravating wear, thereby extending the service life of the cable and saddle 1.

[0037] Furthermore, the telescopic compensation component 4 also includes multiple mounting brackets 48, which are respectively connected to multiple sliding pads 42. A lead screw 49 is threaded through each mounting bracket 48, with a pressure block 410 connected to the bottom end of the lead screw 49 and a second gear 411 connected to the top end of the lead screw 49. Multiple second gear blocks 412 are rotatably mounted on the saddle 1 via a bracket. A limit rod is provided at the bottom of the connection between the second gear blocks 412 and the saddle 1. The multiple second gear blocks 412 mesh with the multiple second gears 411 respectively. When the sliding pad 42 moves to the right, the mounting brackets 48 drive the lead screw 49 and the second gears 411 to move to the right. When the second gear 411 moves to the right, it rotates through the gear meshing of the second tooth block 412, causing the lead screw 49 to drive the pressure block 410 to move up a small distance. Similarly, when the sliding pad 42 moves to the left, the lead screw 49 drives the pressure block 410 to move down a small distance. By setting multiple pressure blocks 410, the multiple pressure blocks 410 can press the cable tightly, improving the stability between the cable and the sliding pad 42. Through the cooperation of the second gear 411 and the second tooth block 412, the pressure block 410 can adaptively clamp according to the thermal expansion and contraction of the cable, avoiding the pressure block 410 and the sliding pad 42 from deforming when the cable expands and squeezes the pressure block 410.

[0038] In addition, please see Figure 1 , Figure 9 - Figure 12Lubrication component 5 is used to replenish grease to the telescopic compensation component 4. Lubrication component 5 includes two oil tanks 51, both mounted on top of the saddle 1. The two oil tanks 51 are located above the two side grooves 3. An oil chamber 53 is provided inside the first toothed block 43, with hoses 52 and oil injection pipes 56 connected inside. Both hoses 52 and oil injection pipes 56 penetrate the first toothed block 43. A slider 54 is slidably connected to the top of the first toothed block 43, with its bottom located inside the oil chamber 53. Multiple abutment blocks 55 are installed inside the side grooves 3. An oil groove 57 is provided inside the sliding pad 42, with multiple oil holes 58 on the bottom surface of the sliding pad 42 connected to the oil groove 57. Multiple hoses 52 located at the rear are connected to the bottom of the rear oil tank 51, and multiple hoses 52 located at the front are connected to the bottom of the front oil tank 51. Multiple oil injection pipes 56 are connected to multiple oil grooves 57, and multiple abutment blocks 55 are installed inside the side grooves 3. When the contact block 55 moves, it slides into contact with the top of multiple sliders 54. When the slider 54 contacts the contact block 55, the contact block 55 applies a counter-pushing force to the slider 54, causing the slider 54 to move downward. This allows the oil tank 53 to inject grease into the oil groove 57 through the oil injection pipe 56. The oil groove 57 squeezes out the grease through multiple oil holes 58, thereby lubricating the sliding pad 42 and the liner 41. A spring is provided between the bottom surface of the slider 54 and the inner wall of the oil tank 53. When the contact block 55 is not in contact with the slider 54, the slider 54 returns to its original position due to the spring force. Through the setting of the lubrication component 5, when the sliding pad 42 moves, the oil tanks 53 on both sides of the sliding pad 42 can automatically inject grease into the oil groove 57 inside the sliding pad 42, causing the multiple oil holes 58 at the bottom of the sliding pad 42 to squeeze out the grease, lubricating the sliding pad 42 and the liner 41, thereby reducing the friction when the sliding pad 42 moves and extending the service life of the sliding pad 42.

[0039] In addition, two slide rods 510 are slidably connected to the inner wall of the oil tank 53. A connecting rod 59 is hinged between the slider 54 and the two slide rods 510. Multiple disturbance rods 511 are connected to the top surface of the slide rods 510. The two slide rods 510 are mirror images of each other. When the slider 54 moves up and down, it can drive the two slide rods 510 to move left and right through the two connecting rods 59. When the slide rods 510 move, they drive the multiple disturbance rods 511 to move synchronously. Multiple paddles are provided on the disturbance rods 511. When the multiple disturbance rods 511 move, they can agitate the grease in the oil tank 53, making the grease distribution in the oil tank 53 more uniform. Through the setting of multiple disturbance rods 511, the multiple disturbance rods 511 can agitate the grease in the oil tank 53 by moving left and right, thereby maintaining the uniformity of the grease and avoiding uneven grease distribution, which would affect the performance.

[0040] Using the above structure, the working principle of this case is as follows: multiple sliding pads 42 are connected side by side through the cooperation of pins and pin holes to form a multi-section telescopic structure. The top surface of the liner 41 is smooth, and multiple sliding pads 42 can slide on the liner 41 to a certain extent. The cable is attached to multiple sliding pads 42. When the cable expands due to heat, the cable above the saddle 1 extends to the right; when the cable contracts due to cold, the cable above the saddle 1 contracts to the left. When the cable contracts, it drives multiple sliding pads 42 to slide on the liner 41. This allows the multi-section telescopic structure of multiple sliding pads 42 to slide on the liner 41 in conjunction with the thermal expansion and contraction of the cable, reducing cable... The frictional force generated during cable extension and contraction; the telescopic column 44 and the cable have the same coefficient of thermal expansion, and the amount of extension and contraction under the same temperature change is also the same. Since the left end of the telescopic column 44 is fixed on the saddle 1, the telescopic column 44 will also extend to the right after being heated. Therefore, when the cable extends to the right, the two telescopic columns 44 also extend to the right. The right ends of the two telescopic columns 44 respectively drive the two levers 45 to swing clockwise, causing the two levers 45 to drive the two arc-shaped racks 46 to slide to the left. Taking the same side groove 3 as an example, when the arc-shaped rack 46 in the side groove 3 moves to the left, it drives the multiple first gears 47 to drive the multiple first tooth blocks 43 to move to the right. Conversely, the two... When the telescopic column 44 retracts to the left upon cooling, the two arc-shaped racks 46 slide to the right, and multiple first tooth blocks 43 move to the left, connecting with the sliding pad 42. The two first tooth blocks 43, when moving left and right, drive the sliding pad 42 to move synchronously left and right. The first gear 47 is a double-layer gear configuration. The outer gears of multiple first gears 47 are of the same size, and the size and number of teeth of the inner gears of multiple first gears 47 within the same side groove 3 increase sequentially from left to right. The outer gears of the first gear 47 mesh with the arc-shaped racks 46, and the inner gears of the first gear 47 mesh with the first tooth blocks 43. Therefore, when the arc-shaped racks 46 move the same distance, the leftmost... The sliding pad 42 on the side moves the least from left to right. The movement range of multiple sliding pads 42 increases sequentially from left to right. Since the actual movement range of different parts of the cable also increases sequentially from left to right when the cable is extended or retracted, the movement range of multiple sliding pads 42 following the extension and retraction of the two extension columns 44 matches that of the cable. Therefore, when the cable is extended or retracted, multiple sliding pads 42 can extend and retract synchronously through cooperation. The sliding pads 42 are changed from being passively slid by the friction force of the cable extension and retraction to actively sliding to cooperate with the cable extension and retraction, thereby reducing the lateral compressive stress on the sliding pads 42 when the cable is extended or retracted, and achieving the effect of extension and retraction compensation.Multiple mounting brackets 48 are installed after the cable installation is completed. The height of the pressure block 410 can be adjusted by rotating the screw 49 via the second gear 411, causing the pressure block 410 to tightly press against the cable, thereby improving the stability between the cable and the sliding pad 42. The second toothed block 412 can flip upwards. After the second toothed block 412 swings downwards, the limiting block at the bottom of the second toothed block 412 limits its engagement with the second gear 411. After the second toothed block 412 flips upwards, it disengages from the second gear 411. When the operator manually adjusts the tightness of the pressure block 410, after the second toothed block 412 meshes with the second gear 411, the sliding pad 42 moves to the right, driving the lead screw 49 and the second gear 411 to move to the right via the mounting bracket 48. The second gear 411 rotates through the meshing of the second toothed block 412, causing the lead screw 49 to move the pressure block 410 upwards a small distance. Similarly, when the sliding pad 42 moves to the left, the lead screw 49 moves the pressure block 410 downwards a small distance. Since the rightward movement of the sliding pad 42 represents the cable's thermal expansion, the cross-section of the cable will also... A slight expansion of the cable, coupled with a slight upward movement of the pressure block 410, prevents excessive pressure on the pressure block 410 after cable expansion, thus avoiding deformation of the pressure block 410, lead screw 49, mounting bracket 48, and sliding pad 42. Similarly, when the cable contracts, the pressure block 410 moves downward to maintain pressure on the cable, thereby maintaining the clamping effect. The telescopic compensation component 4 allows multiple sliding pads 42 to coordinate and extend synchronously during cable expansion and contraction. The multiple sliding pads 42 assist the cable in its expansion and contraction through their own movement, thereby reducing cable stretching. The lateral compressive stress generated on the sliding pad 42 during contraction achieves the effect of expansion and contraction compensation, avoiding local stress concentration in the cable and thus preventing accelerated wear, thereby extending the service life of the cable and saddle 1. The arrangement of multiple pressure blocks 410 allows them to compress the cable, improving the stability between the cable and the sliding pad 42. Through the cooperation of the second gear 411 and the second gear block 412, the pressure blocks 410 can adaptively clamp according to the thermal expansion and contraction of the cable, preventing deformation of the pressure blocks 410 and the sliding pad 42 caused by the cable expanding.

[0041] The oil tank 51 contains grease. During the rightward movement of the first toothed block 43, the slider 54 contacts the abutment block 55. The abutment block 55 applies a counter-force to the slider 54, causing it to move downward. This downward movement increases the internal pressure of the oil tank 53, causing the oil tank 53 to inject grease into the oil groove 57 through the oil injection pipe 56. The oil groove 57 then squeezes out the grease through multiple oil holes 58, thus lubricating the sliding pad 42 and the liner 41. Both the oil injection pipe 56 and the hose 52 are equipped with check valves, ensuring the grease flows only in one direction. When the abutment block 55 is not in contact with the slider 54, the slider 54 resets due to the spring force, reducing the internal pressure of the oil tank 53. The oil tank 53 then draws grease from the oil tank 51 through the hose 52, saturating the oil tank 53 with grease. The slider 54's up-and-down movement can then drive two sliding rods 5 through two connecting rods 59. When the slide bar 510 moves left and right, it drives multiple disturbance bars 511 to move synchronously. Multiple paddles are installed on the disturbance bars 511. When these bars move, they agitate the grease in the oil tank 53, making the grease distribution more uniform. Through the lubrication assembly 5, when the slide pad 42 moves, the oil tanks 53 on both sides of the slide pad 42 automatically inject grease into the oil grooves 57 within the slide pad 42. This causes multiple oil holes 58 at the bottom of the slide pad 42 to squeeze out the grease, lubricating the area between the slide pad 42 and the liner 41. This reduces friction during the movement of the slide pad 42 and extends its service life. The multiple disturbance bars 511 also agitate the grease in the oil tank 53 by moving left and right, maintaining the uniformity of the grease and preventing uneven grease distribution that could affect performance.
