Description

Technical Field

[0001] The utility model relates to the field of crane hooks, in particular to a tower crane hook assembly transfer frame. Background Art

[0002] In the existing processing and handling process, in addition to manual handling, various auxiliary tools are used for handling between various processes during the actual production process, thereby reducing the labor intensity of workers and improving production efficiency. However, the hook assembly of the crane is prone to shaking due to the shaking of the hook during transportation, causing damage to items between products, causing the paint coated on the surface to break and fall off, and affecting product quality.

[0003] Prior art CN202221229086.1 discloses a transport auxiliary device for a crane vehicle frame, comprising a first device housing, a second device housing fixedly mounted on the top of the first device housing, a mounting slot provided inside the second device housing, a transport rotating wheel rotatably mounted inside the mounting slot, second bearing seats fixedly mounted on both side surfaces of the second device housing, first bearing seats fixedly mounted on both side surfaces of the first device housing, a control panel fixedly mounted on one side surface of the first device housing, the control panel located between the first bearing seats, a mounting base fixedly mounted on the bottom of the first device housing, universal wheels fixedly mounted on the four corners of the bottom of the mounting base, a fixed seat fixedly mounted on the bottom of the mounting base, and the fixed seat is located on one side of the universal wheel, rotating gears rotatably mounted on both sides of the second device housing, a rotating shaft fixedly mounted on one side of the rotating gear, the rotating shaft passing through both sides of the second device housing and rotatably connected to the second bearing seat, and track groups rotatably mounted on both sides of the interior of the first device housing. Although this utility model can transport crane vehicle frames, it still has the following problems:

[0004] 1. This device is mainly designed for the transportation of crane frames, and is not specifically optimized for the shaking problem of tower crane hook components during transportation. For components such as hooks with unstable center of gravity, they are prone to large shaking during transportation. However, this device fails to provide effective fixing measures and cannot ensure the stability of the hook during transportation.

[0005] 2. The existing method of transporting hook components is to transport the components from the manufacturer to the assembly factory. When loading, the components are usually stacked in the truck compartment in sequence. However, during transportation, when encountering road bumps or emergency braking, the impact force generated by the inertia of the hook cannot be avoided to cause damage to the product itself or other items. It is also unavoidable that the damage caused by the tipping of the component itself cannot be avoided, resulting in damage to the surface coating and affecting product quality. Utility Model Content

[0006] In view of this, the purpose of the present invention is to provide a tower crane hook assembly transfer frame, which fixes the hook assembly by adopting the cooperation of support beams and limit rods to prevent the hook assembly from colliding during the transfer process and ensure product quality.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Provided is a tower crane hook assembly transfer frame, comprising: a support frame, a support beam, a limit rod and a positioning beam;

[0009] The support frame is provided with two support beams parallel to each other through an adjusting device. The support beam is arranged on the upper end cross beam of the support frame across the support frame, and the spacing between the support beams can be adjusted by the adjusting device. The limit rods are evenly distributed on the support beam along the axial direction of the support beam, and the distance between adjacent limit rods is not less than the thickness of the hook assembly. The positioning beam is symmetrically arranged on the support frame below the support beam corresponding to the bottom of the extension part of the hook assembly, and can support the extension part of the hook assembly.

[0010] It should be noted that the support frame provides basic support for the overall structure, and the support beams are installed on the support frame through an adjustment device. The adjustment device allows the user to adjust the distance between the support beams according to the actual size of the hook assembly, ensuring that the transfer frame can adapt to hook assemblies of different specifications while maintaining its stability during transportation; the limit rods are evenly distributed along the axial direction of the support beams, and the distance between adjacent limit rods is not less than the thickness of the hook assembly, which ensures that each hook assembly has sufficient space to avoid collision and friction damage that may occur during transportation. In addition, such a design also allows the hook assemblies to be neatly arranged on the transfer frame for easy management and operation; the positioning beam is set to correspond to the bottom of the extension of the hook assembly, which can provide additional support for these components. For some hook assemblies with special shapes or longer extensions, this design is particularly important because it can prevent the hook assembly from moving unnecessary during transportation, thereby reducing potential risks, ensuring that the hook assembly remains stable during transportation, and reducing the risk of damage to the hook assembly during transportation.

[0011] Preferably, the adjustment device includes a positioning screw and a locking nut, an adjustment groove is provided on the upper end cross beam along its axial direction, and through holes are provided at both ends of the support beam corresponding to the adjustment groove. The positioning screw is arranged in the adjustment groove after passing through the through hole, and can fix the two ends of the support beam by cooperating with the locking nut and the locking screw.

[0012] It should be noted that the positioning screw passes through the through holes at both ends of the support beam and is embedded in the adjustment slot on the upper cross beam. When the position of the support beam needs to be adjusted, the locking nut is loosened to allow the positioning screw to slide in the adjustment slot, thereby changing the distance between the support beams. Once adjusted to the appropriate position, the positioning screw is fixed by tightening the locking nut to ensure that the support beam will not be displaced during transportation; the operator can quickly adjust the position of the support beam according to actual conditions, reducing preparation time and workload, enhancing the adaptability of the transfer frame to hook assemblies of different sizes, and ensuring stability after adjustment.

[0013] Preferably, the limiting rods, the positioning beams, and the support beams between the limiting rods are all wrapped with flexible pads.

[0014] It should be noted that the flexible pad can be made of rubber pad, sponge pad, foam plastic pad or other materials with similar properties. Wrapping it on the limit rod, positioning beam and support beam can effectively prevent the hook assembly from direct contact with metal parts and prevent the surface of the hook assembly from being scratched or damaged. Especially for those components with coated or painted surfaces, it can well protect their appearance quality. In addition, during transportation, even if it encounters bumps or impacts, the flexible pad can also play a certain shock-absorbing role, reducing the risk of damage caused by vibration, thereby ensuring the safety and integrity of the hook assembly.

[0015] Preferably, a suspension rod is provided on the support frame between the support beams, and a suspension rope for hanging a suspension hook is correspondingly provided on the suspension rod.

[0016] It should be noted that the boom and the rope thereon are used to suspend the hook, so that it remains suspended during transportation, reducing the impact of ground vibration on the hook assembly, reducing the impact of inertia on the hook assembly during transportation, and improving the safety and stability of transportation.

[0017] Preferably, support feet are correspondingly provided at the four corners of the bottom of the support frame.

[0018] It should be noted that the support legs provide a more stable foundation for the transfer rack, especially on uneven or soft ground, ensuring that the transfer rack will not easily tilt or overturn, and also allowing a forklift to smoothly insert into the bottom of the transfer rack to transport it.

[0019] Preferably, the two ends of the positioning beam are adjustably arranged on the middle crossbeam of the support frame, and a sliding groove is provided on the middle crossbeam in an axially extended manner. Slide blocks are provided at the two ends of the positioning beam corresponding to the sliding groove. The positioning beam can move axially along the middle crossbeam through the cooperation of the sliding groove and the slider.

[0020] It should be noted that the design of the slide and slider enables the positioning beam to be adjusted according to the specific size and shape of the hook assembly, ensuring that the extension of each hook assembly can be properly supported, enhancing the adaptability of the transfer frame to hook assemblies of different specifications, and avoiding shaking or collision caused by improper support, further ensuring transportation safety.

[0021] Preferably, the cross-section of the positioning beam is L-shaped as a whole, and the sliding block is arranged on the lower surface of the positioning beam.

[0022] It should be noted that since the cross-section of the positioning beam is "L"-shaped, its vertical and horizontal parts can directly support the bottom of the extension of the hook assembly, while the vertical part can limit the side of the extension to prevent the extension from sliding on the positioning beam during transportation, effectively limiting the lateral movement of the hook assembly, thereby significantly improving the safety and stability of transportation.

[0023] Beneficial effects of the utility model:

[0024] The utility model provides a tower crane hook assembly transfer rack, which loads the produced hook assemblies by forming an overall frame through components such as a support frame, a support beam, a limit rod and a positioning beam, thereby preventing the hook assemblies from colliding during the transfer process; the support beams can adjust the spacing through an adjustment device to accommodate hook assemblies of different sizes; the limit rods are distributed axially along the support beams to ensure that the distance between adjacent limit rods is not less than the thickness of the hook assembly, thereby avoiding direct contact and possible damage between the hook assemblies. The use of the transfer rack not only improves the safety and stability of the hook assembly during the transfer process, but also improves the compatibility of the transfer rack with hook assemblies of different sizes and types through flexible design, reduces the risk of product damage, and also facilitates operators to make quick adjustments according to actual conditions, thereby reducing workload and preparation time.

[0041] The cross section of the positioning beam 4 is L-shaped as a whole, and the slider 41 is arranged on the lower surface of the positioning beam 4 .

[0042] The working principle and use method of a tower crane hook assembly transfer rack of this embodiment:

[0043] This embodiment provides a tower crane hook assembly transfer frame, the support frame 1 is the basic structure of the entire transfer frame, which provides a location for installation and fixing of all other components, the support beam 2 is arranged across the support frame 1 on the upper end cross beam 11, and the distance between the two support beams 2 can be adjusted by the adjustment device 5. This design enables the transfer frame to adapt to hook assemblies 7 of different sizes, ensuring stability during transportation; the adjustment device 5 is composed of a positioning screw 51 and a locking nut 52. The positioning screw 51 passes through the through holes 21 at both ends of the support beam 2 and is embedded in the adjustment slot 1 on the upper end cross beam 11. 11, when the distance between the support beams 2 needs to be changed, the locking nut 52 is loosened to allow the positioning screw 51 to slide in the adjustment slot 111; after adjusting to the desired position, the locking nut 52 is tightened again to fix the position of the support beam 2; the limiting rods 3 are evenly distributed along the axial direction of the support beam 2, and the distance between adjacent limiting rods 3 is not less than the thickness of the hook assembly 7. This design ensures that each hook assembly 7 has enough space to avoid possible collision and friction damage during transportation, and also helps to arrange the hook assembly 7 neatly on the transfer rack for easy management and operation; the positioning beams 4 are evenly distributed along the axial direction of the support beam 2, and the distance between adjacent limiting rods 3 is not less than the thickness of the hook assembly 7. The bottom of the extension 71 of the hook assembly 7 is symmetrically arranged on the support frame 1 below the support beam 2, which can provide additional support for these components. For the hook assembly 7 with a special shape or a longer extension 71, this can prevent it from moving unnecessary during transportation, thereby reducing potential risks and ensuring that the hook assembly 7 remains stable during transportation; the flexible pad is wrapped around the limit rod 3, the positioning beam 4 and the support beam 2, and is made of materials such as rubber pads, sponge pads, and foam plastic pads. It can effectively prevent the hook assembly 7 from direct contact with metal parts and prevent surface scratches or damage. Especially for those components with coated or painted surfaces, in addition, when encountering bumps or impacts, the flexible pad can also play a certain shock-absorbing role, reducing the risk of damage caused by vibration; the two ends of the positioning beam 4 cooperate with the slider 41 through the slide groove 131, and can move axially along the middle cross beam 13. This design enables the positioning beam 4 to be adjusted according to the specific size and shape of the hook assembly 7, ensuring that the extension 71 of each hook assembly 7 can be properly supported, thereby enhancing the adaptability of the transfer frame to hook assemblies 7 of different specifications, and avoiding shaking or collision caused by improper support.

[0044] During use, according to the specific size of the hook assembly 7 to be transported, loosen the locking nut 52 and adjust the distance between the support beams 2 to ensure that the distance between the support beams 2 is suitable for the width of the hook assembly 7 and leave enough space to avoid collision. Then, according to the position of the extension 71 of the hook assembly 7, move the position of the positioning beam 4 along the slide groove 131 so that it can provide support for the extension 71 of the hook assembly 7. Then, place the hook assembly 7 into the transfer rack in turn, ensuring that each assembly is separated by the limit rod 3 and its extension 71 is supported by the positioning beam 4. Then hang the hook on the lifting rope 61 to complete the placement of the hook assembly 7. Finally, use a forklift or other lifting equipment to move the transfer rack equipped with the hook assembly 7 to the transfer vehicle for transportation. After arriving at the destination, first check whether the hook assembly 7 has signs of damage, and then carefully remove the hook assembly 7 in the reverse order of loading to ensure that no damage is caused to the product during operation and complete the transfer of the hook assembly 7.
