Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and particularly relates to a heavy-duty saddle device for a cable tower top. Background Art

[0002] In recent years, the main spans of large bridges have been continuously broken through, and the installation scale of offshore wind power equipment has continued to expand. There is a relatively large application of cable cranes in engineering construction. A cable crane is composed of components such as a tower, cables, a lifting device, and a cable tower. Among them, the cable tower, as a key support, shoulders the heavy responsibility of maintaining the stability of the overall structure. The heavy-duty saddle at the top of the cable tower not only guides the direction of the cable, ensures the effective transmission of force during the lifting process, but also bears a huge lifting weight, directly determining the safety performance and working efficiency of the cable crane. The heavy-duty saddle is usually connected to the cable through a specific cable groove. The design of the cable groove fully considers the shape and stress characteristics of the cable to ensure close fit between the two.

[0003] However, in the prior art, there are the following problems:

[0004] When constructing in areas with large temperature differences between day and night, the thermal expansion and contraction of the cable are relatively frequent. Since the thermal expansion coefficients of the cable and the saddle material are different, their expansion and contraction amounts are also different under the same temperature change. Due to the large downward pressure of the cable on the saddle, the cable will generate a large lateral extrusion stress on the saddle during thermal expansion and contraction, which intensifies the wear between the cable and the saddle, thereby shortening the service lives of the cable and the saddle.

Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope protected by the present invention.

[0034] Embodiment 1

[0035] Please refer to Figure 1 - Figure 8, a heavy-load saddle device for a cable tower top, comprising a saddle 1, a cable groove 2 is arranged on the saddle 1, and two side grooves 3 are arranged inside the saddle 1, and the two side grooves 3 are respectively located on both sides of the cable groove 2; further comprising a telescopic compensation assembly 4 for compensating the telescopic movement of the cable when the cable expands and contracts due to temperature changes; the telescopic compensation assembly 4 comprises a gasket 41, the gasket 41 is installed in the cable groove 2, a plurality of sliding pads 42 are slidably connected to the gasket 41, two pin holes are arranged on the left side of the sliding pad 42, two pins are arranged on the right side of the sliding pad 42, and the two pins of the sliding pad 42 are slidably connected to the two pin holes of the adjacent sliding pad 42. The plurality of sliding pads 42 are connected side by side through the cooperation of the pins and the pin holes to form a multi-section telescopic structure. The top surface of the gasket 41 is smooth, and each of the plurality of sliding pads 42 can slide on the gasket 41 to a certain extent. The cable is fitted and installed on the plurality of sliding pads 42. When the cable contracts, it drives the plurality of sliding pads 42 to slide on the gasket 41, so that the multi-section telescopic structure of the plurality of sliding pads 42 slides on the gasket 41 in cooperation with the thermal expansion and contraction of the cable, reducing the friction generated when the cable expands and contracts.

[0036] Further, first tooth blocks 43 are respectively connected to both sides of the sliding pad 42. The two first tooth blocks 43 are respectively located in the two side grooves 3. Telescopic columns 44 are respectively slidably connected to the outer walls on both sides of the saddle 1 through a plurality of brackets. Two pry bars 45 are rotatably installed at the right end of the saddle 1 through brackets. Arc-shaped racks 46 are respectively slidably connected in the two side grooves 3. A plurality of first gears 47 are rotatably installed in the side grooves 3. The left end of the telescopic column 44 is fixed to the saddle 1 through a fixing member. The tops of the two pry bars 45 are respectively slidably hinged to the right ends of the two telescopic columns 44. The bottoms of the two pry bars 45 are respectively hinged to the right ends of the two arc-shaped racks 46. When the right end of the telescopic column 44 moves, the arc-shaped rack 46 is driven to move in the reverse direction through the pry bar 45 by using the lever principle. A through hole is provided between the side groove 3 and the cable groove 2. The connection part of 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 arranged as a double-layer gear. The inner gears of the plurality of first gears 47 are respectively meshed with the plurality of first tooth blocks 43. The outer gears of the plurality of first gears 47 in the same side groove 3 are all meshed with the arc-shaped rack 46. The outer gears of the plurality of first gears 47 are of the same size. The sizes and numbers of teeth of the inner gears of the plurality of first gears 47 in the same side groove 3 increase sequentially from left to right. The outer gear of the first gear 47 is meshed with the arc-shaped rack 46, and the inner gear of the first gear 47 is meshed with the first tooth block 43. Therefore, when the arc-shaped rack 46 moves the same distance, the leftmost sliding pad 42 moves the smallest amplitude left and right, and the moving amplitudes of the plurality of sliding pads 42 increase sequentially from left to right. When the cable expands and contracts, the plurality of sliding pads 42 can synchronously expand and contract through cooperation. The passive sliding of the sliding pad 42 due to the friction force during the expansion and contraction of the cable is changed to the active sliding of the sliding pad 42 to cooperate with the expansion and contraction of the cable, thereby reducing the lateral extrusion stress generated on the sliding pad 42 during the expansion and contraction of the cable, achieving the effect of expansion and contraction compensation. Through the setting of the expansion and contraction compensation assembly 4, the plurality of sliding pads 42 can synchronously expand and contract through cooperation when the cable expands and contracts. The plurality of sliding pads 42 assist the cable to expand and contract through their own movements, thereby reducing the lateral extrusion stress generated on the sliding pad 42 during the expansion and contraction of the cable, achieving the effect of expansion and contraction compensation, avoiding local stress concentration of the cable and aggravating wear, and thus prolonging the service life of the cable and the saddle 1.

[0037] Furthermore, the telescopic compensation component 4 further includes a plurality of mounting brackets 48, the plurality of mounting brackets 48 are respectively connected to the plurality of sliding pads 42, a lead screw 49 is threadedly connected through the mounting bracket 48, a pressing block 410 is connected to the bottom end of the lead screw 49, a second gear 411 is connected to the top end of the lead screw 49, a plurality of second tooth blocks 412 are rotatably mounted on the saddle 1 through brackets, a limiting rod is arranged at the bottom of the connection between the second tooth block 412 and the saddle 1, the plurality of second tooth blocks 412 are respectively engaged with the plurality of second gears 411. When the sliding pad 42 moves to the right, the lead screw 49 and the second gear 411 are driven to move rightward through the mounting bracket 48. When the second gear 411 moves rightward, it rotates due to the gear engagement of the second tooth block 412, so that the lead screw 49 drives the pressing block 410 to move upward by a small distance. Similarly, when the sliding pad 42 moves leftward, the lead screw 49 drives the pressing block 410 to move downward by a small distance. Through the arrangement of the plurality of pressing blocks 410, the plurality of pressing 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 pressing block 410 can adaptively clamp according to the thermal expansion and contraction of the cable, avoiding deformation of the pressing block 410 and the sliding pad 42 caused by the cable expanding and squeezing the pressing block 410.

[0038] In addition, please refer to Figure 1 , Figure 9 - Figure 12, a lubrication assembly 5 for replenishing grease to the telescopic compensation assembly 4; the lubrication assembly 5 includes two oil tanks 51, both of the two oil tanks 51 are installed on the top of the saddle 1, the two oil tanks 51 are respectively located above the two side grooves 3, an oil chamber 53 is arranged inside the first tooth block 43, a hose 52 and an injection pipe 56 are connected inside the oil chamber 53, both the hose 52 and the injection pipe 56 penetrate through the first tooth block 43, a slider 54 is slidably connected through the top of the first tooth block 43, the bottom of the slider 54 is located inside the oil chamber 53, a plurality of abutting blocks 55 are installed in the side groove 3, an oil groove 57 is arranged inside the sliding pad 42, a plurality of oil holes 58 are arranged on the bottom surface of the sliding pad 42, the oil holes 58 are connected with the oil groove 57, the plurality of hoses 52 at the rear are respectively connected with the bottom of the rear oil tank 51, the plurality of hoses 52 at the front are respectively connected with the bottom of the front oil tank 51, the plurality of injection pipes 56 are respectively connected with the plurality of oil grooves 57, when the plurality of abutting blocks 55 move, they respectively make sliding contact with the tops of the plurality of sliders 54, when the slider 54 contacts the abutting block 55, the abutting block 55 applies a reaction force to the slider 54 to cause the slider 54 to move downward, so that the oil chamber 53 injects grease into the oil groove 57 through the injection pipe 56, and the oil groove 57 extrudes the grease through the plurality of oil holes 58, thereby lubricating between the sliding pad 42 and the gasket 41. A spring is arranged between the bottom surface of the slider 54 and the inner wall of the oil chamber 53. When the abutting block 55 does not contact the slider 54, the slider 54 is reset by the elastic force of the spring. Through the arrangement of the lubrication assembly 5, when the sliding pad 42 moves, the oil chambers 53 on both sides of the sliding pad 42 can automatically inject grease into the oil groove 57 inside the sliding pad 42, so that the plurality of oil holes 58 at the bottom of the sliding pad 42 extrude the grease, lubricating between the sliding pad 42 and the gasket 41, thereby reducing the friction when the sliding pad 42 moves and prolonging the service life of the sliding pad 42.

[0039] In addition, two sliding rods 510 are slidably connected to the inner wall of the oil chamber 53, connecting rods 59 are respectively hinged between the slider 54 and the two sliding rods 510, a plurality of disturbing rods 511 are connected to the top surface of the sliding rods 510, the two sliding rods 510 are arranged in a mirror image. When the slider 54 moves up and down, it can drive the two sliding rods 510 to move left and right through the two connecting rods 59. When the sliding rods 510 move, they drive the plurality of disturbing rods 511 to move synchronously. A plurality of paddles are arranged on the disturbing rods 511. When the plurality of disturbing rods 511 move, they can stir the grease in the oil chamber 53, making the grease in the oil chamber 53 more evenly distributed. Through the arrangement of the plurality of disturbing rods 511, the plurality of disturbing rods 511 can stir the grease in the oil chamber 53 by moving left and right, thereby maintaining the evenness of the grease and avoiding uneven texture of the grease, which affects the use effect.

[0040] With the above structure, the working principle of this case is that 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 gasket 41 is smooth, and multiple sliding pads 42 can all slide on the gasket 41 to a certain extent. The cable is fitted and installed on 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 gasket 41, so that the multi-section telescopic structure of multiple sliding pads 42 slides on the gasket 41 in cooperation with the thermal expansion and contraction of the cable, reducing the frictional force generated when the cable expands and contracts; the telescopic column 44 has the same coefficient of thermal expansion as the cable, and the telescopic amount 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, and the right ends of the two telescopic columns 44 drive the two pry bars 45 to swing clockwise respectively, so that the two pry bars 45 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 multiple first tooth blocks 43 to move to the right through multiple first gears 47. On the contrary, when the two telescopic columns 44 contract to the left due to cold, the two arc-shaped racks 46 slide to the right, and multiple first tooth blocks 43 move to the left. The two first tooth blocks 43 connected to the sliding pad 42 drive the sliding pad 42 to move left and right synchronously when moving left and right. The first gear 47 is arranged as a double-layer gear. The outer gears of multiple first gears 47 are of the same size, and the inner gears of multiple first gears 47 in the same side groove 3 increase in size and number of teeth from left to right in sequence. 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 smallest amplitude left and right, and the moving amplitudes of multiple sliding pads 42 increase from left to right in sequence. Since when the cable expands and contracts, the actual moving amplitudes of different parts also increase from left to right in sequence, the moving amplitudes of multiple sliding pads 42 following the expansion and contraction of the two telescopic columns 44 match the cable. Therefore, when the cable expands and contracts, multiple sliding pads 42 can perform synchronous expansion and contraction through cooperation, changing from the sliding of the sliding pad 42 being passive to the frictional force when the cable expands and contracts to the active sliding of the sliding pad 42 to cooperate with the expansion and contraction of the cable, thereby reducing the lateral extrusion stress generated on the sliding pad 42 when the cable expands and contracts, achieving the effect of expansion and contraction compensation;Multiple mounting brackets 48 are installed after the cable installation. By rotating the lead screw 49 through the second gear 411, the height of the pressing block 410 can be adjusted to tightly press the cable against the cable, thereby improving the stability between the cable and the sliding pad 42. The second tooth block 412 can be turned up. After the second tooth block 412 swings downward, the limiting block at the bottom of the second tooth block 412 limits the second tooth block 412 to keep the second tooth block 412 engaged with the second gear 411. After the second tooth block 412 is turned up, it disengages from the second gear 411, facilitating manual adjustment of the pressing degree of the pressing block 410 by the staff. After the second tooth block 412 is engaged with the second gear 411, when the sliding pad 42 moves to the right, it drives the lead screw 49 and the second gear 411 to move to the right through the mounting bracket 48. When the second gear 411 moves to the right, it rotates through the gear meshing action of the second tooth block 412, causing the lead screw 49 to drive the pressing block 410 to move up a small distance. Similarly, when the sliding pad 42 moves to the left, the lead screw 49 drives the pressing block 410 to move down a small distance. Since the rightward movement of the sliding pad 42 represents the thermal expansion of the cable, when the cable expands, its cross-section will also expand slightly. After the pressing block 410 moves up slightly, it can prevent the cable from exerting a large extrusion force on the pressing block 410 when it expands, resulting in deformation of the pressing block 410, the lead screw 49, the mounting bracket 48, and the sliding pad 42. Similarly, when the cable contracts, the pressing block 410 moves down to maintain the pressure on the cable, thereby maintaining the clamping effect. Through the setting of the telescopic compensation assembly 4, multiple sliding pads 42 can synchronously expand and contract through cooperation when the cable expands and contracts. Multiple sliding pads 42 assist the cable to expand and contract through their own movements, thereby reducing the lateral extrusion stress generated on the sliding pads 42 when the cable expands and contracts, achieving the effect of telescopic compensation, avoiding local stress concentration of the cable and aggravating wear, and thus extending the service life of the cable and the saddle 1. Through the setting of multiple pressing blocks 410, multiple pressing 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 pressing block 410 can be adaptively clamped according to the thermal expansion and contraction of the cable, avoiding the deformation of the pressing block 410 and the sliding pad 42 caused by the extrusion of the pressing block 410 when the cable expands.;

[0041] The fuel tank 51 is filled with grease. During the rightward movement of the first tooth block 43, the slider 54 contacts the abutting block 55, and the abutting block 55 exerts a reaction force on the slider 54, causing the slider 54 to move downward. When the slider 54 moves downward, the internal pressure of the oil chamber 53 increases, causing the oil chamber 53 to inject the grease into the oil groove 57 through the injection pipe 56. The oil groove 57 extrudes the grease through a plurality of oil holes 58, thereby lubricating between the sliding pad 42 and the gasket 41. Check valves are provided in both the injection pipe 56 and the hose 52, enabling the grease to flow only in one direction. When the abutting block 55 does not contact the slider 54, the slider 54 is reset by the elastic force of the spring, reducing the internal pressure of the oil chamber 53. The oil chamber 53 extracts the grease from the fuel tank 51 through the hose 52, keeping the grease in the oil chamber 53 in a saturated state. When the slider 54 moves up and down, it can drive two sliding rods 510 to move left and right through two connecting rods 59. When the sliding rods 510 move, they drive a plurality of disturbing rods 511 to move synchronously. A plurality of paddles are provided on the disturbing rods 511. When the plurality of disturbing rods 511 move, they can stir the grease in the oil chamber 53, making the distribution of the grease in the oil chamber 53 more uniform; through the setting of the lubrication assembly 5, when the sliding pad 42 moves, the oil chambers 53 on both sides of the sliding pad 42 can automatically inject the grease into the oil groove 57 inside the sliding pad 42, and the plurality of oil holes 58 at the bottom of the sliding pad 42 extrude the grease, lubricating between the sliding pad 42 and the gasket 41, thereby reducing the friction force when the sliding pad 42 moves and extending the service life of the sliding pad 42; through the setting of the plurality of disturbing rods 511, the plurality of disturbing rods 511 can stir the grease in the oil chamber 53 by moving left and right, thereby maintaining the uniformity of the grease and avoiding uneven texture of the grease, which may affect the use effect.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
