Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of hoisting fixtures, specifically to a hoisting fixture for the motor of a gantry crane traveling mechanism. Background Technology

[0002] In the operation and maintenance of gantry cranes, the traveling mechanism motor is the core component ensuring the crane's movement function. When the motor malfunctions and needs repair or replacement, the lifting fixture is the key equipment for safely assembling and disassembling the motor. Its angle adjustment flexibility and support stability directly determine the efficiency and safety of the lifting operation. As gantry cranes develop towards larger and heavier loads, the weight and volume of the traveling mechanism motor are constantly increasing, and the shortcomings of traditional lifting fixtures are becoming increasingly prominent: existing fixtures generally have the disadvantages of being inconvenient to adjust the lifting angle and having poor support strength and stability, which not only increases the difficulty of operation but also easily causes safety hazards and is difficult to adapt to the lifting requirements of heavy motors.

[0003] Traditional lifting fixtures often employ fixed supports and single lifting points, requiring manual prying or adjustment with auxiliary tools to adjust the lifting angle. This process is cumbersome and lacks precision. The motor mounting position of the traveling mechanism in a gantry crane is unique, often obstructed by components such as the chassis and rails. Fixed-angle lifting fixtures struggle to accurately align with the motor lifting point, leading to issues like skewed lifting ropes and motor tilting, increasing the difficulty of assembly and disassembly. Furthermore, traditional fixture supports are often simple welded structures with insufficient support strength. When lifting heavy motors, the supports are prone to deformation or swaying, failing to stably support the motor's weight and posing a risk of the motor falling.

[0004] Therefore, the development of a gantry crane traveling mechanism motor hoisting fixture that can flexibly adjust the lifting angle and has stable support strength has become an urgent need to improve operation and maintenance efficiency and operational safety. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a hoisting fixture for the motor of a gantry crane traveling mechanism, which solves the technical problems that existing fixtures in the prior art generally have the disadvantages of inconvenience in adjusting the lifting angle and poor support strength stability.

[0006] According to one aspect, at least one embodiment of this disclosure provides a hoisting fixture for the motor of a gantry crane traveling mechanism, comprising: A connecting seat and a front frame, wherein the front frame is mounted on the connecting seat; An angle adjustment assembly is disposed between the front frame and the connecting seat; A telescopic support assembly is disposed on the front frame and the connecting seat; The angle adjustment assembly includes a pair of upright plates, which are fixed at both ends of the surface of the connecting seat. A rotating shaft is horizontally rotatably connected between the upright plates. The lower end of the front frame is fixedly connected to the rotating shaft. A worm gear is installed on the rotating shaft. An installation cavity is formed in the surface of the connecting seat.

[0007] As a further technical solution, a connecting frame is provided on the top of the connecting seat, and a worm gear is vertically rotatably connected between the bottom of the mounting cavity and the connecting frame. The worm gear meshes with the worm wheel, and a drive motor is provided inside the mounting cavity.

[0008] As a further technical solution, the output end of the drive motor is provided with a drive gear, and the lower end of the worm is provided with a transmission gear, wherein the drive gear meshes with the transmission gear.

[0009] According to another aspect, in at least one embodiment of the present invention, the telescopic support assembly includes a transmission cavity, the transmission cavity being opened within the front frame, a telescopic rod being movably inserted and connected within the transmission cavity, and a pair of lifting rings being provided at the bottom of the upper end of the telescopic rod.

[0010] As a further technical solution, a connecting block is provided on the top of the front frame, and an internally threaded block is rotatably connected inside the connecting block. A stud is provided on the upper end face of the telescopic rod, and the stud is connected to the internally threaded block by threaded engagement.

[0011] As a further technical solution, a guide frame is provided at the bottom of the front frame, a movable sleeve is slidably connected to the guide frame, an anti-slip groove is provided on the bottom surface of the guide frame, and a support column is connected to the bottom of the movable sleeve by a threaded connection.

[0012] As a further technical solution, the upper end of the support column is attached to the anti-slip groove, a horizontal column is fixedly connected to the connecting seat, a stabilizing column is movably connected to the horizontal column, and the upper end of the stabilizing column is rotatably connected to the bottom of the movable sleeve by a pin.

[0013] As a further technical solution, the outer surface of the internal thread block is a polygonal structure.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the angle adjustment component solves the problems of difficult angle adjustment and unstable fixation in traditional tooling through precise transmission and self-locking design. The drive motor drives the front frame to rotate smoothly through multi-stage transmission of gears and worm gears, which can accurately adapt to the angle requirements of the motor installation position and avoid angle deviation caused by manual prying; the self-locking characteristics of the worm gear ensure that there is no risk of the front frame falling back after adjustment, and it can maintain a stable angle even when carrying a heavy motor. The upright plate and connecting frame provide stable support for the transmission components, and the mounting cavity protects the transmission structure from the influence of impurities. This structure significantly reduces the difficulty of angle adjustment, improves the accuracy of hoisting alignment, avoids motor collisions or installation difficulties caused by improper angles, and is suitable for the complex operation and maintenance environment of gantry cranes.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, it illustrates a hoisting fixture for the motor of a gantry crane traveling mechanism according to an embodiment of this disclosure, comprising: A connecting base 1 and a front frame 2, wherein the front frame 2 is mounted on the connecting base 1; An angle adjustment component 3 is disposed between the front frame 2 and the connecting seat 1; Telescopic support assembly 4, which is disposed on the front frame 2 and the connecting seat 1; The angle adjustment assembly 3 includes a pair of upright plates 3-1, which are fixed at both ends of the surface of the connecting seat 1. A rotating shaft 3-2 is horizontally rotatably connected between the upright plates 3-1. The lower end of the front frame 2 is fixedly connected to the rotating shaft 3-2. A worm gear 3-3 is installed on the rotating shaft 3-2. An installation cavity 3-4 is opened in the surface of the connecting seat 1. A connecting frame 3-5 is provided on the top of the connecting seat 1. A worm 3-6 is vertically rotatably connected between the bottom of the installation cavity 3-4 and the connecting frame 3-5. The worm 3-6 meshes with the worm gear 3-3. A drive motor 3-7 is provided in the installation cavity 3-4. A drive gear 3-8 is provided at the output end of the drive motor 3-7. A transmission gear 3-9 is provided at the lower end of the worm 3-6. The drive gear 3-8 meshes with the transmission gear 3-9.

[0024] In some examples, in order to achieve stable adjustment of the hoisting angle of the front frame 2 and avoid installation alignment difficulties caused by angle deviation during motor hoisting, an angle adjustment component 3 is designed. This component includes vertical plates 3-1 at both ends of the surface of the connecting seat 1 to provide horizontal rotation support for the rotating shaft 3-2. The lower end of the front frame 2 is fixed on the rotating shaft 3-2, so that the front frame 2 can rotate synchronously with the rotating shaft 3-2, thereby adjusting the hoisting angle. The worm gear 3-3 on the rotating shaft 3-2 meshes with the worm 3-6 between the vertical plate 3-1 to form a reduction transmission structure. Utilizing the self-locking characteristics of the worm gear 3-3 and the worm 3-6, it is ensured that the front frame 2 can be stably fixed after being adjusted to the target angle, preventing the angle from falling back due to the weight of the motor.

[0025] The drive motor 3-7 inside the mounting cavity 3-4 on the surface of the connecting seat 1 meshes with the transmission gear 3-9 at the lower end of the worm 3-6 through the drive gear 3-8 at the output end, forming a power transmission path. The drive motor 3-7 drives the drive gear 3-8 to rotate, which is then transmitted to the worm 3-6 through the transmission gear 3-9. The worm 3-6 then drives the worm wheel 3-3 and the rotating shaft 3-2 to rotate, thereby realizing the electric adjustment of the angle of the front frame 2.

[0026] This multi-stage transmission structure can reduce the load on drive motors 3-7, and at the same time improve the accuracy of angle adjustment by reducing speed, so that the front frame 2 can adjust the angle slowly and smoothly, avoiding sudden angle changes that could cause motor swaying.

[0027] The mounting cavity 3-4 provides a protective space for the drive motor 3-7 and the transmission gear 3-9 to prevent impurities from entering and affecting the transmission during hoisting; the connecting frame 3-5 provides rotational support for the top of the worm 3-6 to ensure that the worm 3-6 and the worm wheel 3-3 are always precisely meshed.

[0028] During operation, drive motor 3-7 drives worm gear 3-6 and worm wheel 3-3 to rotate, thereby adjusting the angle of front frame 2. Precise transmission ensures controllable angle, and self-locking characteristics ensure stable position. All components work together to adjust the angle of front frame 2, meeting the motor's hoisting angle adaptation requirements.

[0029] like Figures 1-4 As shown in the figure, this embodiment proposes that the telescopic support assembly 4 includes a transmission cavity 4-1, which is opened in the front frame 2. A telescopic rod 4-2 is movably inserted into the transmission cavity 4-1. A pair of lifting rings 4-3 are provided at the bottom of the upper end of the telescopic rod 4-2. A connecting block 4-4 is provided at the top of the front frame 2. An internally threaded block 4-5 is rotatably fitted into the connecting block 4-4. A stud 4-6 is provided on the upper end face of the telescopic rod 4-2. The stud 4-6 is threadedly connected to the internally threaded block 4-5. The bottom of the front frame 2... The unit is equipped with a guide frame 4-7, on which a movable sleeve 4-8 is slidably connected. The bottom surface of the guide frame 4-7 is provided with an anti-slip groove 4-9. The bottom of the movable sleeve 4-8 is connected to a support column 4-10 by a threaded connection. The upper end of the support column 4-10 is attached to the anti-slip groove 4-9. A horizontal column 4-11 is fixedly connected to the connecting seat 1. A stabilizing column 4-12 is installed on the movable sleeve 4-8 on the horizontal column 4-11. The upper end of the stabilizing column 4-12 is rotatably connected to the bottom of the movable sleeve 4-8 by a pin.

[0030] In some examples, to achieve flexible adaptation of the lifting length and stable support during the lifting process, and to avoid safety hazards caused by insufficient length or unstable support during motor lifting, a telescopic support assembly 4 is designed. This assembly includes a transmission cavity 4-1 in the front frame 2 to provide movement space for the telescopic rod 4-2. The internal threaded block 4-5 in the top connecting block 4-4 of the front frame 2 is threadedly engaged with the stud 4-6 on the upper end face of the telescopic rod 4-2. Rotating the internal threaded block 4-5 drives the stud 4-6 to move the telescopic rod 4-2 along the transmission cavity 4-1 to extend and retract, thereby adjusting the height of the lifting ring 4-3 to adapt to the lifting length requirements of motors of different specifications. The precision of the threaded transmission ensures accurate length adjustment and avoids deviations in lifting height.

[0031] The guide frame 4-7 at the bottom of the front frame 2 provides horizontal sliding guidance for the movable sleeve 4-8. The support column 4-10 at the bottom of the movable sleeve 4-8 is threaded into the anti-slip groove 4-9 on the bottom surface of the guide frame 4-7. The toothed structure of the anti-slip groove 4-9 can prevent the support column 4-10 from sliding and enhance the support stability. The stabilizing column 4-12 on the horizontal column 4-11 is rotatably connected to the bottom pin of the movable sleeve 4-8 to form a triangular support structure, which further improves the support strength of the movable sleeve 4-8 and prevents the movable sleeve 4-8 from shifting during hoisting.

[0032] After the telescopic rod 4-2 is adjusted to the target length, slide the movable sleeve 4-8 to the appropriate position, tighten the support column 4-10 so that it is pressed against the anti-slip groove 4-9, and cooperate with the triangular support of the stabilizing column 4-12 to provide stable support for the front frame 2 and prevent the front frame 2 from shaking during the hoisting process.

[0033] The lifting ring 4-3 provides a connection point for motor hoisting, and its symmetrical layout ensures that the motor is subjected to balanced force; the internal thread block 4-5 has a convenient and labor-saving rotation adjustment method, and the length can be adjusted without the need for complicated tools.

[0034] During operation, rotate the internal threaded block 4-5 to adjust the length of the telescopic rod 4-2, slide the movable sleeve 4-8, and tighten the support column 4-10 to fix it. The threaded telescopic mechanism is compatible with multiple specifications, and the anti-slip support ensures stability. All components work together to complete the length adjustment and stable support, meeting the requirements for safe motor hoisting.

[0035] For example, such as Figure 2 As shown, the outer surface of the internal thread block 4-5 has a polygonal structure.

[0036] In some examples, the polygonal structure around the outer surface of the internal thread block 4-5 provides a stable force point for tool clamping, preventing tool slippage when adjusting the length of the telescopic rod 4-2 by rotating the internal thread block 4-5. Workers can use general tools such as wrenches to precisely engage the polygonal structure and apply force, easily driving the internal thread block 4-5 to rotate. Compared to a circular surface, it is easier to control the rotation force and speed, ensuring smooth extension and retraction of the telescopic rod 4-2 and preventing jamming between the stud 4-6 and the internal thread block 4-5 due to uneven force.

[0037] In actual use: Fix the connecting seat 1 to the lifting equipment. According to the installation position of the motor of the gantry crane's traveling mechanism, start the angle adjustment component 3. The drive motor 3-7 drives the drive gear 3-8 to rotate, which is transmitted to the worm 3-6 through the transmission gear 3-9. The worm 3-6 meshes with the worm wheel 3-3 on the rotating shaft 3-2, driving the front frame 2 to rotate around the rotating shaft 3-2 and adjust to the appropriate lifting angle. The self-locking characteristics of the worm wheel 3-3 and worm 3-6 ensure the stable fixation of the front frame 2. Then operate the telescopic support component 4. Use a tool to rotate the polygonal internal thread block 4-5. Through the stud 4-6, drive the telescopic rod 4-2 to extend and retract along the transmission cavity 4-1 of the front frame 2. Adjust the height of the lifting ring 4-3 to match the motor lifting point. After extension and retraction, slide the movable sleeve 4-8 on the sliding guide frame 4-7 to the appropriate position. Tighten the support column 4-10 so that its upper end fits against the anti-slip groove 4-9. At the same time, the stabilizing column 4-12 moves with the movable sleeve 4-8 to form a triangular support. Connect the lifting rope to the lifting ring 4-3 and the motor to lift the motor smoothly. Precise adjustment of angle and length can be achieved throughout the process to ensure lifting safety.
