Description

Technical Field

[0001] The present invention relates to the technical field of gantry cranes, in particular to a roller hoisting clamp tooling. Background Art

[0002] A gantry crane (also known as a gantry crane or portal crane) is a type of crane with a bridge supported on ground tracks by outriggers on both sides. Its structure consists of a gantry, a trolley running mechanism, a hoisting trolley, and electrical components. Some gantry cranes have outriggers on only one side, with the other side supported on a factory building or pier. These are called semi-gantry cranes. A gantry crane consists of the upper gantry bridge (including the main girder and end beams), outriggers, and a lower crossbeam. Single-girder gantry cranes offer a simple structure, easy manufacture and installation, and low weight. Their main girder is often an off-track box-type structure. Compared to twin-girder gantry cranes, their overall rigidity is weaker. The legs are angled or curved to create more lateral space for cargo to pass through the legs. Twin-girder gantry cranes offer high load capacity, large spans, excellent overall stability, and a wide variety of models. However, they are heavier and more expensive than single-girder gantry cranes of the same lifting capacity. Depending on the main girder structure, they can be categorized as box-girder or truss-type. A box-shaped structure is generally used, with the main beam constructed from welded angle steel or I-beams. This structure offers advantages such as low cost, light weight, and good wind resistance. However, due to the numerous weld points and inherent flaws in the truss structure, truss beams also suffer from significant deflection, low rigidity, relatively low reliability, and the need for frequent weld inspection. It is therefore suitable for sites with lower safety requirements and smaller lifting loads.

[0003] Replacing the gantry crane's trolley rollers is a mandatory task after the gantry crane wheels arrive at the factory. Due to their large size and weight, the rollers are awkwardly positioned for each lift. Furthermore, their lower edges contact the rails, making them difficult and time-consuming to secure with wire rope. Furthermore, there's a risk of slippage during lifting after tying. Furthermore, when replacing the gantry crane wheels, their excessive weight can easily cause them to over-rotate when adjusting the angle. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6, a roller hanging clamp tooling, including a hanging seat 1, a bearing 2 is clamped on the lower surface of the hanging seat 1, a rotating group 3 is inserted on one side of the hanging seat 1, a retaining spring seat 4 is provided inside the rotating group, and the internal rotation of the retaining spring seat 4 is connected with a spring clamp group 5, the surface of the bearing 2 is sleeved with a gear group 6, and the interior of the gear group 6 is inserted with a lifting column 7, one end of the lifting column 7 is sleeved with a top shaft sleeve 9, and the surface of the top shaft sleeve 9 is provided with a limiting shaft 10, and the surface of the limiting shaft 10 is sleeved with an A inclined plate 11 and a B inclined plate 12 from the inside to the outside, and the interior of the B inclined plate 12 is inserted with a screw group 13, the A inclined plate 11 includes a fixing rod 14, and one end of the A inclined plate 11 is inserted with a load-bearing shaft 15. In the maintenance of traditional gantry cranes, rollers are also of paramount importance. Considering that the track will be subjected to various external forces to varying degrees during the actual operation of the gantry crane, resulting in problems such as displacement and deformation, long-term action will induce wheel rail gnawing failure. Therefore, to ensure the track remains in good working condition, flexible track adjustment is crucial. Before track adjustment, the outer surface of the track should be inspected for cracks and fissures. The track gauge should also be measured, the overall height adjusted, and track straightness corrected using wire ropes. Bolts or track clamps should be checked for looseness. Minor deformation can be adjusted locally. Severe deformation requires replacing the track or raising the track foundation. Secondly, the wheel assembly installation accuracy must be reliably controlled. Three common methods are: First, using a larger wheel flange height: The wheel flange is raised by 50% from the original height. This improves the contact between the wheel flange and the track side under load, reducing stress, preventing wheel flange wear, and improving durability. Second, adjusting the wheel gauge: Current design specifications require that for typical gantry cranes, the track gauge error should be strictly controlled within ±S(span) / 1000. There are two specific adjustment methods: adjusting the keyplates securing the wheel bearings and adjusting the length of the bearing sleeves. It is recommended to control the adjustment range within 8.0~10.0mm; thirdly, make reasonable adjustments to the diagonal of the wheel group: based on practical work experience, it is believed that in order to ensure the coaxiality of the mechanical transmission system and reduce maintenance workload, the passive wheel should be adjusted, and the active wheel should be adjusted as much as possible to solve the error problem in the diagonal installation link. Therefore, when installing the tooling and clamping the roller 17, it is also very important to adjust the angle.

[0029] See also Figure 2-6A roller hanging clamp tool includes a rotating group 3 including a support rod 301, a manual rotating shaft 302, and a handle rod 303. The support rod 301 is inserted on one side of the hanging seat 1. The internal rotation of the support rod 301 is connected to the manual rotating shaft 303, and the internal sliding connection of the manual rotating shaft 302 is connected to the handle rod 303. According to the mutual cooperation between the manual rotating shaft 302 and the handle rod 303 in the rotating group 3, when the handle rod 303 is rotated to the top position and released, it will slide to the bottom position, which is convenient for applying force when rotating. At the same time, when the handle rod 303 is rotated, the bevel gear 602 in the gear group 6 and the planetary gear 601 meshing with it can be rotated. During rotation, the spring bottom plate 502 and the block 504 arranged inside the spring clamp group 5 will jump downward through the gear squeezing the block 504.

[0030] It should be noted that the planetary gear 601 will not rotate in the opposite direction. The angle of the roller 17 can be adjusted step by step. The angle comparison scale 8 is engraved on the raised column 7 below the planetary gear 601, which can more conveniently observe and adjust the angle to be adjusted. The material of the block 504 in this device must be carbon tool steel. Commonly used hardened plastic mold steels include: low alloy cold working die steel such as 9SiCr, 9Mn2V steel, Cr12 steel such as Cr12MoV steel, high speed steel such as W6Mo5Cr4V2 steel, matrix steel and some hot working die steel, etc. The hardness after heat treatment is usually above 45-50HRC. Similarly, the most commonly used steel for gears is 20CrMnTi. This steel has fine grains and a low tendency for grain growth during carburizing, resulting in excellent carburizing and quenching properties. It can be quenched directly after carburizing. my country's carburizing alloy structural steels (including 20CrMnTi steel) only guarantee the chemical composition and mechanical properties of the steel as measured by samples when leaving the factory. However, during production, it is common for steel with acceptable chemical composition and mechanical properties to experience wide fluctuations in hardenability, affecting product quality. For example, if the hardenability of 20CrMnTi carburizing steel is too low, the core hardness of the gear produced after carburizing and quenching will be lower than the value specified in the technical specifications, and the fatigue life of the gear will be reduced by half during fatigue testing. If the hardenability is too high, the internal bore of the gear will shrink significantly after carburizing and quenching, affecting gear assembly. Therefore, carbon tool steel can be used to make gear set 6. The meshing teeth of the gear set can be covered with flexible grease after quenching to increase the smoothness of rotation.

[0031] The limiting shaft 10 includes a limiting fixed shaft 1001, a positioning sleeve 1002, and a spring 1003. The two sides of the fixed shaft 1001 are respectively connected with an A inclined plate 11 and a B inclined plate 12. The surface of the fixed shaft 1001 is sleeved with a top sleeve 9. The two sides of the top sleeve 9 are clamped with springs 1003. One end of the spring 1003 is clamped with a positioning sleeve 1002. The positioning sleeve is provided on the surface of the fixed shaft 1001. The spring 1003 clamped with the positioning sleeve 1002 can adjust the overall balance of the tooling. The spring 1003 is a mechanical part that works by elasticity. Parts made of elastic materials are deformed under the action of external force and return to their original shape after the external force is removed. It is also called "spring". It is generally made of spring steel or high-toughness steel. Coil springs and scroll springs are primarily used. Traditional mechanical springs, while strong, are susceptible to volatility. Therefore, air springs can be used instead. These are non-metallic springs that utilize the compressibility of air by adding pressurized air to a flexible, sealed container to achieve elasticity. Air springs can be broadly categorized as bladder and membrane types. Furthermore, due to their numerous advantages over conventional steel springs, both types can be incorporated into this fixture. Adjustments can be made based on usage to avoid deformation, such as widening at the top and narrowing at the bottom, caused by excessive weight on roller 17. This prevents the fixture from becoming unfastened when roller 17 is placed. It should be noted that roller 17 is schematically illustrated. After the roller 17 forging process has passed the forging process, the forging can be rough-turned after cooling. This rough-turning process involves machining the mounting holes and keyway. The workpiece then undergoes comprehensive heat treatment, quenching, normalizing, and conditioning. Heat treatment involves heating, holding, and cooling a material in a solid state to achieve the desired microstructure and properties. After heat treatment, the product is subjected to hardness testing and other tests before entering the finishing stage. Finishing is done on a high-speed controlled lathe to control the dimensions to the drawing requirements. The accuracy margin is 0.02mm to 0.03mm. There are many processes, so the roller 17 is hoisted when it is installed to avoid damage or collision to the roller, which affects the operation of the gantry crane. The factors that lead to wheel rail gnawing failure are mainly the following two aspects: First, the horizontal deflection problem of the wheel mainly refers to the fact that during the wheel installation process, the horizontal deflection amount is not controlled, and the track centerline and the wheel centerline are not in a coincident state, forming a certain angle. When the angle formed is greater than 0.5°, the wheel rail gnawing failure will occur. Second, the vertical deflection problem of the wheel mainly refers to the influence of the structural deformation factors of the gantry crane itself. The plumb line and the wheel tread centerline form a poor angle, which increases the wheel running radius and significantly increases the distance of one circle.In addition to the above factors, the deviation of the transmission performance of the transmission system and the design and installation defects of the track itself will increase the incidence of wheel rail gnawing failure. Therefore, this tooling can be used to clamp rollers 17 of different sizes and sizes. The position of the limit sleeve 1502 in the load-bearing shaft 15 is adjustable. According to actual use test results, polyamide, high-strength nylon, and thermoplastic resin containing repeating amide groups are used. According to needs, conventional rubber materials are very easy to deform when clamping the roller 17. Therefore, high-strength nylon material is used, which has better support and reversible deformation effects. Under the heavy pressure of the roller 17, there will be no deviation. The main reason for the walking failure is that due to the high structural rigidity of the entire gantry crane, it is difficult to ensure that the four fulcrums are in the same plane during normal operation, especially during the walking action. In addition, since the oil circuit connection of the gantry crane's walking motor is parallel, and considering that the pressure value of the hydraulic system will be affected by the load force factor, the uneven track leads to different pressure levels required to drive the hydraulic motor. The travel wheel with the smallest pressure value will rotate first, which may cause the travel wheel to be suspended, and the corresponding drive motor load value to be the smallest, and it will continuously idle or stop rotating.

[0032] The screw group 13 includes a threaded shaft 1301, a screw 1302, and a screw handle 1303. The internal rotation of the B inclined plate 13 is connected to the threaded shaft 1301, and the internal thread of the threaded shaft 1301 passes through the screw 1302. One end of the screw 1302 is rotatably connected to the fixed rod 14, and the other end of the screw 1302 is provided with a screw handle 1303. The A inclined plate 11 and the B inclined plate 12 are rotatably connected to the load-bearing shaft 15 and the limit shaft 10. The surface of the load-bearing shaft 15 can be clamped with the roller 17 through the limit sleeve 1502. According to the requirements of different sizes of the roller 17, the spring in the limit shaft 10 can be adjusted to adjust the width. The screw group 13 can be adjusted by the screw handle 1303 to open and close the A inclined plate 11 and the B inclined plate 12 in this tooling. It is worth noting that When the tooling is in use, both ends of the limit shaft 10, the threaded shaft 1302, the fixed rod 14, and the load-bearing shaft 15 can be clamped with positioning terminals such as positioning springs or fixing buckles, so that the width of the A inclined plate 11 and the B inclined plate 12 can be adjusted to better match rollers 17 of different sizes. In the event of a travel failure, the specific repair method can be considered from two aspects: the configuration of the number of drive wheels and the oil circuit connection method: the first method is to increase the number of drive wheels equipped with the original gantry crane to 8, and connect every two drive wheels with pins to form a balanced drive wheel, ensuring that the travel wheels can still follow the ups and downs of the track under the conditions of track ups and downs, thereby increasing the contact area between the two; the second method is to change the parallel connection of the motor oil circuit to a combination of series and parallel oil circuit connection mode. In this way, it is ensured that at least one motor drives the wheel to work at each fulcrum, avoiding the problem of idling and slipping due to uneven force. Therefore, when replacing the faulty roller 17, the center of gravity position of the faulty roller 17 is difficult to control, which can easily cause the hoist clamp to twist and deform.

[0033] When in use, a limit hook 16 is welded on the upper surface of the tooling hanger 1, and is hung with the hand hoist through the limit hook 16. A bearing 2 is clamped at the center position inside the hanger 1, and a support rod 301 is inserted at one side of the hanger 1. The internal manual rotating shaft is rotated through the handle rod 303 to rotate the bevel gear 602 and engage the planetary gear 601 to adjust the angle. At the same time, an angle comparison scale 8 is vertically opened on the surface position of the lifting column 7, and the adjustable angle can be observed. By rotating the screw handle 1303 in the screw group 13, the A inclined plate 11 and the B inclined plate 12 are opened and adjusted. After opening the tooling, the limit sleeve 1502 can be clamped to the roller 17. After clamping, the screw handle 1303 is rotated to close the tooling and clamp it. When the tooling is lifted, the positioning sleeve 1002 and the spring 1003 play a role. The spring 1003 can adjust the top supporting force to avoid dislocation and deformation of the tooling.

[0034] To sum up, the roller hanging clamp fixture, based on the mutual cooperation between the manual rotating shaft 302 and the handle rod 303 in the rotation group 3, will slide to the bottom position when the handle rod 303 is rotated to the top position and released, making it easier to apply force when rotating. At the same time, when the handle rod 303 is rotated, the bevel gear 602 in the gear group 6 and the planetary gear 601 meshed with it can be rotated. During rotation, the spring bottom plate 502 and the block 504 arranged inside the spring clamp group 5 will jump downward through the gear squeezing block 504.

[0035] The planetary gear 601 will not rotate in the opposite direction. The angle of the roller 17 can be adjusted step by step. At the position of the rising column 7 below the planetary gear 601, there is an angle comparison ruler 8, which can more conveniently observe and adjust the angle that needs to be adjusted. The spring 1003 connected to the positioning sleeve 1002 can adjust the overall balance of the tooling. The spring 1003 uses elasticity to work as a mechanical part.

[0036] During use, both ends of the limit shaft 10, threaded shaft 1302, fixed rod 14, and load-bearing shaft 15 can be clamped with positioning terminals such as positioning springs or fixing buckles, and the width of the A inclined plate 11 and the B inclined plate 12 can be adjusted to better match rollers 17 of different sizes.
