Description

Technical Field

[0001] This utility model belongs to the technical field of hoist head assembly drive equipment, specifically relating to a floating hinge support structure for a large hoist head assembly drive equipment. Background Technology

[0002] Traditional hoist drive equipment support structures mostly use rigid brackets directly fixed to the outside of the main unit. Such structures have good stability under static loads, but have significant defects in dynamic working conditions: when the drive equipment is running, the equipment's own weight and operation will generate torque and vibration, and the rigid connection cannot absorb the vibration energy generated by the drive equipment during operation. The load is concentrated at the connection point, which can easily lead to vibration deformation or cracking at the welded position. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a floating hinge support structure for the head assembly drive equipment of a large hoist.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a floating hinge support structure for a large hoist head assembly drive device, disposed on the outside of the hoist head assembly device, wherein drive devices are respectively installed on both sides of the hoist head assembly device. This floating hinge support structure includes a triangular support frame. One side of the triangular support frame has a vertical connecting frame connected to the outside of the hoist head assembly device. The upper end of the triangular support frame has a horizontal mounting frame. Both ends of the horizontal mounting frame are respectively connected to one end of a vertically arranged floating hinge, and the other end of the floating hinge is connected to one end of the drive device. The lower end of the triangular support frame is provided with a support foot assembly connected to the hoist head assembly device. The triangular support frame, formed by the combination of the vertical connecting frame and the horizontal mounting frame, forms a stable triangular mechanical structure. Utilizing the stability principle of a triangle, the load of the drive device can be effectively distributed.

[0005] In the aforementioned floating hinge support structure for the head assembly drive equipment of a large hoist, the horizontal mounting frame is rectangular, and both ends of the horizontal mounting frame extend below the two drive devices. Extending the horizontal mounting frame below the two drive devices reduces redundant design, lowers costs, and ensures uniform force distribution on both drive devices.

[0006] In the aforementioned floating hinge support structure for a large hoist head assembly drive device, the horizontal mounting frame includes two parallel horizontal beams and two parallel horizontal longitudinal beams. Several connecting beams are sequentially arranged between the horizontal longitudinal beams, and reinforcing longitudinal beams are provided between the connecting beams. The horizontal beams, horizontal longitudinal beams, connecting beams, and reinforcing longitudinal beams form a grid structure. Through optimized mechanical distribution, this increases frame stiffness while reducing weight, preventing bending deformation under long-term loads. Furthermore, the multi-beam connection disperses vibration loads, reducing the risk of resonance, making it particularly suitable for conditions where high-frequency vibrations occur during equipment operation.

[0007] In the aforementioned floating hinge support structure for a large hoist head assembly drive device, rectangular mounting platforms are respectively provided at both ends of the horizontal mounting frame on the side away from the hoist head assembly device. This provides a standardized installation interface for the floating hinge, ensuring the accuracy of the hinge connection position and avoiding uneven stress caused by installation errors.

[0008] In the aforementioned floating hinge support structure for a large hoist head assembly drive unit, hinge seats are movably connected to both ends of the floating hinge. One hinge seat at one end of the floating hinge is connected to the lower side of one end of the drive unit, and the other hinge seat at the other end of the floating hinge is connected to a rectangular mounting platform. The movable connection of the hinge seats allows the drive unit to undergo small displacements during operation, avoiding stress concentration caused by rigid connections and extending the equipment's lifespan. Simultaneously, the floating characteristic absorbs the impact loads during drive unit startup / shutdown, reducing damage to the support structure and the equipment itself.

[0009] In the aforementioned floating hinge support structure for a large hoist head assembly drive device, the vertical connecting frame is rectangular and is mounted on the outside of the hoist head assembly device via fixing components. The vertical connecting frame is connected to the outside of the device via fixing components, forming a stable vertical support that transfers the load of the horizontally mounted frame to the main body of the device, ensuring structural integrity.

[0010] In the above-mentioned floating hinge support structure for a large hoist head assembly drive device, a bottom longitudinal beam is provided below the horizontal longitudinal beam on the side of the horizontal mounting frame near the hoist head assembly device, and a column is provided between the two ends of the horizontal longitudinal beam and the two ends of the bottom longitudinal beam, and the horizontal longitudinal beam, the bottom longitudinal beam and the column together form the above-mentioned vertical connecting frame.

[0011] In the aforementioned floating hinge support structure for a large hoist head assembly drive device, the fixing component includes several mounting columns disposed on one side of the hoist head assembly device. The upper ends of the mounting columns are respectively abutted and connected to the sides of the horizontal longitudinal beam and the bottom longitudinal beam. The mounting columns abut and connect the device to the frame, eliminating the need for complex mounting holes in the device body, avoiding weakening the device's strength, and facilitating disassembly and adjustment.

[0012] In the aforementioned floating hinge support structure for a large hoist head assembly drive device, several inclined beams are sequentially arranged between the bottom longitudinal beam and the side of the horizontal mounting frame away from the hoist head assembly device. These inclined beams connect the bottom longitudinal beam and the horizontal mounting frame, forming a triangular support unit that enhances the structure's torsional stiffness in the horizontal direction and prevents lateral deformation of the frame.

[0013] In the above-mentioned floating hinge support structure of a large hoist head assembly drive device, the support foot assembly includes a support inclined beam disposed on the lower side of both ends of the bottom longitudinal beam and disposed at a relative angle, and the lower end of the support inclined beam is connected to the lower end of the hoist head assembly device.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. The triangular support frame of this device forms a triangular structure through a vertical connecting frame, a horizontal mounting frame, and an inclined beam. By utilizing the geometric stability principle of a triangle, it increases the bending resistance and significantly improves the structural strength, while also preventing the hinge point installation position from sinking or deforming.

[0016] 2. The device uses a floating hinge, which allows the drive equipment to float or swing slightly in the vertical direction, absorbing the vibration energy of the drive equipment during operation and reducing stress concentration caused by rigid connection. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3 As shown, a floating hinge support structure for a large hoist head assembly drive device is provided on the outside of the hoist head assembly device 1. Drive devices 11 are installed on both sides of the hoist head assembly device 1. This floating hinge support structure includes a triangular support frame 2. One side of the triangular support frame 2 has a vertical connecting frame 4 connected to the outside of the hoist head assembly device 1. The upper end of the triangular support frame 2 has a horizontal mounting frame 5. Both ends of the horizontal mounting frame 5 are connected to one end of a vertically arranged floating connecting hinge 6, and the other end of the floating connecting hinge 6 is connected to one end of the drive device 11. The lower end of the triangular support frame 2 is provided with a support foot assembly 3 connected to the hoist head assembly device 1. The triangular support frame 2, formed by the combination of the vertical connecting frame 4 and the horizontal mounting frame 5, forms a stable triangular mechanical structure. Utilizing the stability principle of a triangle, the load of the drive device 11 can be effectively distributed.

[0023] Combination Figure 1 and Figure 3 As shown, the horizontal mounting frame 5 is rectangular, and both ends of the horizontal mounting frame 5 extend below the two drive devices 11. Extending the horizontal mounting frame 5 below the two drive devices 11 reduces redundant design, lowers costs, and ensures that the drive devices 11 on both sides are subjected to uniform force.

[0024] The horizontal mounting frame 5 includes two parallel horizontal beams 51 and two parallel horizontal longitudinal beams 52. Several connecting beams 53 are sequentially arranged between the horizontal longitudinal beams 52, and reinforcing longitudinal beams 54 are arranged between the connecting beams 53. The horizontal beams 51, horizontal longitudinal beams 52, connecting beams 53, and reinforcing longitudinal beams 54 form a grid structure. Through optimized mechanical distribution, this structure increases frame stiffness while reducing weight, preventing bending deformation under long-term loads. Furthermore, the multi-beam connection disperses vibration loads, reducing the risk of resonance, making it particularly suitable for operating conditions where high-frequency vibrations occur during equipment operation.

[0025] Specifically, rectangular mounting platforms 55 are provided at both ends of the horizontal mounting frame 5 on the side away from the hoist head assembly equipment 1. These platforms provide standardized installation interfaces for the floating link hinges 6, ensuring the accuracy of the hinge connection positions and avoiding uneven stress caused by installation errors.

[0026] Furthermore, hinge seats 61 are movably connected to both ends of the floating hinge 6. One end of the hinge seat 61 is connected to the lower side of one end of the drive device 11, and the other end of the hinge seat 61 is connected to the rectangular mounting platform 55. The movable connection of the hinge seats 61 allows the drive device 11 to undergo small displacements during operation, avoiding stress concentration caused by rigid connections and extending the equipment's lifespan. At the same time, the floating characteristic can absorb the impact loads during the start-up / stop of the drive device 11, reducing damage to the supporting structure and the equipment itself.

[0027] Furthermore, the vertical connecting frame 4 is rectangular and is mounted on the outside of the hoist head assembly equipment 1 via the fixing component 7. The vertical connecting frame 4 is connected to the outside of the equipment via the fixing component 7, forming a stable vertical support, transferring the load of the horizontal mounting frame 5 to the main body of the equipment, and ensuring the integrity of the structure.

[0028] Meanwhile, a bottom longitudinal beam 56 is provided below the horizontal longitudinal beam 52 on the side of the horizontal mounting frame 5 near the hoist head assembly equipment 1, corresponding to the horizontal longitudinal beam 52. A column 57 is provided between the two ends of the horizontal longitudinal beam 52 and the two ends of the bottom longitudinal beam 56, and the horizontal longitudinal beam 52, the bottom longitudinal beam 56 and the column 57 together form the above-mentioned vertical connecting frame 4.

[0029] Combination Figure 1 and Figure 2 As shown, the fixing component 7 includes several mounting columns 71 disposed on one side of the hoist head assembly equipment 1. The upper ends of the mounting columns 71 are respectively abutted and connected to the side of the horizontal longitudinal beam 52 and the side of the bottom longitudinal beam 56. The mounting columns 71 abut and connect the equipment and the frame, eliminating the need to open complex mounting holes on the main body of the equipment, avoiding weakening the strength of the equipment, and facilitating disassembly and adjustment.

[0030] Combination Figure 1 and Figure 3 As shown, several inclined beams 58 are sequentially arranged between the bottom longitudinal beam 56 and the side of the horizontal mounting frame 5 away from the hoist head assembly equipment 1. The inclined beams 58 connect the bottom longitudinal beam 56 and the horizontal mounting frame 5 to form a triangular support unit, which enhances the torsional stiffness of the structure in the horizontal direction and prevents lateral deformation of the frame.

[0031] The support foot assembly 3 includes a support inclined beam 31 that is set on the lower side of both ends of the bottom longitudinal beam 56 and is relatively inclined, and the lower end of the support inclined beam 31 is connected to the lower end of the hoist head assembly equipment 1.

[0032] The principle of this embodiment is as follows:

[0033] The vertical connecting frame 4 of the triangular support frame 2 is fixed to the outside of the hoist head assembly equipment 1 through the installation column 71 and the support inclined beam 31. The vertical connecting frame 4, the horizontal installation frame 5 and the inclined beam 58 form a stable triangular mechanical structure, which enhances the structure's anti-overturning ability and can avoid structural deformation caused by single-point stress. At the same time, the floating link hinge 6 is set vertically, and its two ends are connected to the drive equipment 11 and the rectangular installation platform 55 respectively through the hinge seat 61. When the drive equipment 11 vibrates or has a small displacement during operation, the hinge can rotate around the connection point, allowing the equipment to float in the vertical direction and a small horizontal direction, avoiding stress concentration caused by rigid connection. Thus, the instantaneous impact force is released through the movement of the hinge, protecting the support structure and the equipment itself.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document frequently uses terms such as hoist head assembly equipment 1, drive equipment 11, triangular support frame 2, support foot assembly 3, support inclined beam 31, vertical connecting frame 4, horizontal mounting frame 5, horizontal crossbeam 51, horizontal longitudinal beam 52, connecting crossbeam 53, reinforcing longitudinal beam 54, rectangular mounting platform 55, bottom longitudinal beam 56, column 57, inclined beam 58, floating link hinge 6, hinge seat 61, fixing assembly 7, and mounting column 71, the possibility of using other terms is not excluded.
