Description

Technical Field

[0001] The embodiments of this utility model relate to the field of mechanical equipment technology, specifically to a mobile maintenance coupling mounting and lifting device. Background Technology

[0002] In the field of mechanical equipment maintenance and installation, coupling installation is a crucial step in ensuring the normal operation of equipment. However, existing technologies often present numerous challenges during coupling installation. For large couplings, their weight and size make height control during lifting extremely difficult, and even slight errors can lead to installation deviations. Furthermore, traditional installation methods rely on manual experience for positioning, making it difficult to accurately align the coupling center with the installation shaft axis, easily resulting in inaccurate positioning. This not only affects installation efficiency but can also lead to vibration and noise problems during equipment operation, and in severe cases, even shorten equipment lifespan, increase maintenance costs, and create safety hazards. Therefore, a new technical solution is urgently needed to address these issues. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a mobile maintenance coupling installation and lifting device, which solves the technical problems of difficulty in controlling the lifting height and inaccurate positioning of large couplings in the prior art.

[0004] According to one aspect, at least one embodiment of the present invention provides a mobile maintenance coupling mounting and lifting device, comprising:

[0005] A support plate is movably mounted on one side of the main shaft of the coupling to be installed; the support plate is equipped with a limiting device and a gripping device.

[0006] The limiting device has a plurality of grippers arranged along the central circumference of the support plate. The plurality of grippers can approach each other and abut against the main shaft or the mounting flange of the main shaft so that the main shaft coincides with the center of the support plate.

[0007] The gripping device is mounted on the support plate and has at least three grippers arranged opposite each other along the center of the support plate. The grippers can approach each other and grip one end of the coupling so that the center of the coupling coincides with the center of the support plate, so that the coupling and the main shaft are concentric.

[0008] The gripping device is used to attach the coupling to the main shaft after the support plate moves.

[0009] For example, in a mobile maintenance coupling installation and lifting device provided in at least one embodiment of this utility model, the first clamp has at least three jaws and is slidably arranged relative to each other along the center of the support plate, and the limiting device further includes:

[0010] A rotating plate, which is rotatably mounted on the support plate;

[0011] The connecting rods are the same number as the grippers, and each connecting rod is hinged at both ends to the rotating plate and one of the grippers.

[0012] The first telescopic member is disposed on the support plate, and its telescopic end is connected to a gripper. After the first telescopic member extends or retracts, it can drive the rotating plate to rotate through the connecting rod so that the multiple grippers slide and move closer or further apart from each other.

[0013] For example, in a mobile maintenance coupling installation and lifting device provided in at least one embodiment of the present invention, the support plate is a double-layer partition, namely partition one and partition two and connected by a connecting sleeve, the rotating plate is rotatably disposed on the outer peripheral wall of the connecting sleeve, the first gripper is slidably disposed on partition one, the second partition is used to connect with the moving device, and one end of the gripping device is disposed on partition one.

[0014] For example, in a mobile maintenance coupling installation and lifting device provided in at least one embodiment of the present invention, the connecting sleeve is a hollow structure with both ends penetrating the first partition and the second partition respectively, one end of the gripping device is located inside the connecting sleeve, and the connecting sleeve is used for the passage of the gripping device's pipeline.

[0015] For example, in a mobile maintenance coupling installation and lifting device provided in at least one embodiment of the present invention, a roller is provided on the gripping end of the first clamp, and the roller is used to roll against the side wall of the main shaft or the mounting flange.

[0016] For example, in a mobile maintenance coupling installation and lifting device provided in at least one embodiment of the present invention, each of the grippers is provided with a plurality of spaced rollers.

[0017] For example, in at least one embodiment of this utility model, a mobile maintenance coupling mounting and lifting device includes a mobile device comprising:

[0018] Mobile cart;

[0019] The second telescopic component is used to be installed on the mobile trolley, and the telescopic direction of the second telescopic component is along the vertical direction;

[0020] The third telescopic component is disposed at the telescopic end of the second telescopic component and the telescopic direction is horizontal. The second partition is disposed at the telescopic end of the third telescopic component.

[0021] For example, in at least one embodiment of this utility model, a mobile maintenance coupling mounting and lifting device is provided, wherein the mobile device further includes:

[0022] A turntable is mounted on the mobile trolley, and a second telescopic member is mounted on the turntable. The turntable enables the third telescopic member to rotate about its axis to adjust the orientation of the limiting device and the gripping device.

[0023] For example, in a mobile maintenance coupling installation and support device provided in at least one embodiment of the present invention, a support plate is installed at the telescopic end of the second telescopic member, and a support bracket is installed on the support plate, the support bracket being used to install the third telescopic member.

[0024] For example, in a mobile maintenance coupling installation and lifting device provided in at least one embodiment of the present invention, a rotation drive component is installed on the mobile trolley, and the rotation drive component is used to drive the turntable to rotate.

[0025] The beneficial effects of the embodiments of this utility model are as follows:

[0026] This invention effectively solves the installation problem of large couplings in the prior art by using a limiting device and a gripping device on the support plate. The first gripper of the limiting device abuts against the main shaft or its mounting flange, aligning the center of the main shaft with the center of the support plate. The second gripper of the gripping device grips the coupling and aligns its center with the center of the support plate. Their coordinated operation ensures concentricity between the coupling and the main shaft. Simultaneously, the gripping device moves with the support plate, fitting the coupling onto the main shaft without complex lifting operations, reducing the difficulty of height control. The entire device achieves positioning and installation during the coupling installation process, significantly improving installation accuracy and efficiency, reducing errors caused by manual operation, lowering safety hazards, and enhancing the reliability and stability of the coupling installation.

[0039] like Figures 1-4 As shown, it illustrates a mobile maintenance coupling mounting and lifting device in one embodiment of the present invention.

[0040] The support plate 1 is designed as a flat plate structure, on which a limiting device 2 and a gripping device 3 are installed. The bottom of the support plate 1 can be connected to the moving device 5 by means of bolts, thereby realizing its movement on the side of the main shaft of the coupling to be installed.

[0041] The limiting device 2 has several grippers 21, which are equidistantly distributed circumferentially along the center of the support plate 1. Each gripper 21 has a slider at its bottom, and correspondingly, the support plate 1 has a radially extending slide rail. The slider and the slide rail cooperate to allow the gripper 21 to slide along the slide rail toward the center of the support plate 1. When the spindle needs to be positioned, the operator controls the grippers 21 to move closer together until the grippers 21 abut against the spindle or the spindle's mounting flange. Through the synchronous movement of multiple grippers 21, the position of the spindle can be adjusted to coincide with the center of the support plate 1, thus completing the positioning of the spindle.

[0042] The gripping device 3 is used to grip the main shaft. At least three grippers 31 of the gripping device 3 are also arranged opposite each other along the center of the support plate 1, and each gripper 31 is connected to a drive mechanism (such as a cylinder or electric push rod). When the coupling needs to be gripped, the drive mechanism actuates, causing the grippers 31 to move closer together and grip one end of the coupling. During the gripping process, the symmetrical distribution and synchronous movement of the grippers 31 ensure that the center of the coupling coincides with the center of the support plate 1. After gripping, the gripping device 3 moves along with the support plate 1 under the drive of the moving device 5, fitting the coupling onto the pre-positioned main shaft, completing the installation operation.

[0043] The support plate 1, serving as the basic load-bearing component, provides an installation platform for the limiting device 2 and the gripping device 3. Through its connection with the moving device 5, it enables overall movement, facilitating the device's proximity to the installation location. The gripper 21 of the limiting device 2, in conjunction with the slide rail on the support plate 1, controls the movement of the gripper 21, achieving stable contact and positioning of the main shaft or mounting flange—more accurate and efficient than manual positioning. The gripping device 3 grips the coupling, ensuring its center coincides with the center of the support plate 1. In conjunction with the limiting device 2, it ensures concentric installation of the coupling and the main shaft. The method of the gripping device 3 moving with the support plate 1 to complete the installation avoids the difficulty of height control in traditional lifting installations, reduces the difficulty and risk of installation operations, significantly improves the accuracy and efficiency of coupling installation, reduces human error, and enhances the reliability and stability of the installation process.

[0044] The support plate 1 has a double-layer partition structure, consisting of partition 11, partition 2 12, and a connecting sleeve 4 connecting partition 11 and partition 2 12. The rotating plate 22 is mounted on the connecting sleeve 4 of the support plate 1 via bearings, enabling the rotating plate 22 to rotate on the support plate 1. One end of the connecting rod 23 is hinged to the rotating plate 22 via a hinge shaft, and the other end is connected to the gripper 21, with each gripper 21 corresponding to one connecting rod 23. The first telescopic member 24 is fixedly installed on the support plate 1, and its telescopic end is connected to one of the grippers 21. When the first telescopic member 24 extends or retracts, it drives the gripper 21 connected to it to slide along the slide rail. Since the connecting rod 23 is hinged to the rotating plate 22, the sliding of the gripper 21 will drive the rotating plate 22 to rotate around the central axis via the connecting rod 23. When the rotating plate 22 rotates, the other connecting rods 23 will move synchronously, thereby driving all the grippers 21 to slide relative to each other along the slide rail, so that multiple grippers 21 move closer or further apart.

[0045] The linkage mechanism, consisting of the first telescopic member 24, the rotating plate 22, and the connecting rod 23, enables the synchronous movement of multiple grippers 21. Compared to controlling each gripper 21 individually, this structure simplifies the control method, improves the consistency and coordination of the gripper 21's movements, and enables faster positioning of the spindle or flange. Driving multiple grippers 21 with a single power source (the first telescopic member 24) reduces the number of power components, lowers the cost of the device, and simultaneously improves the reliability and ease of maintenance of the device.

[0046] The support plate 1 consists of a first partition 11 and a second partition 12, which are arranged in parallel and connected by a connecting sleeve 4. The two ends of the connecting sleeve 4 are fixedly connected to the first partition 11 and the second partition 12 respectively (e.g., by welding or bolting), forming a stable support structure. A rotating plate 22 is mounted on the outer peripheral wall of the connecting sleeve 4 via bearings, allowing it to rotate around the connecting sleeve 4. The first partition 11 is provided with a slide rail for the first gripper 21 to slide on. The first gripper 21 has a slider, which engages with the slide rail to slide on the first partition 11. A moving device 5 is provided on the second partition 12.

[0047] The double-layer partition and connecting sleeve 4 enhance the overall strength and rigidity of the support plate 1, enabling it to better bear the weight of the limiting device 2 and the gripping device 3, as well as the forces exerted during installation. The connecting sleeve 4 provides stable rotational support for the rotating plate 22, ensuring the smooth rotation of the rotating plate 22 and thus guaranteeing the accuracy of the gripper 21's movements. The functional division of partition 11 and partition 22 is clear: partition 11 is used to install the limiting device 2 and the gripping device 3, while partition 22 is used to connect with the moving device 5. This optimizes the structural layout of the device, making the installation of each component more reasonable and facilitating the assembly and maintenance of the device.

[0048] The connecting sleeve 4 adopts a hollow tubular structure, with partition 11 and partition 12 passing through its two ends, respectively. Some components of the gripping device 3 (such as the air pipes and wires for the cylinder driving the gripper 31 or the electric push rod) can pass through the interior of the connecting sleeve 4. The pipes enter from one end of the connecting sleeve 4 and extend out to connect to the external control system. This design allows the pipes of the gripping device 3 to be arranged orderly within the connecting sleeve 4, avoiding exposure and tangling. Simultaneously, concealing the pipes within the connecting sleeve 4 makes the overall structure of the device neater and more aesthetically pleasing, reduces the risk of interference from the pipes to the operation of other components, and facilitates the operation and maintenance of the device.

[0049] At the gripping end of the gripper 21, rollers 210 are mounted via a rotating shaft, allowing the rollers 210 to rotate freely around the shaft. Multiple rollers 210 can be spaced apart on each gripper 21, with the rollers 210 distributed along the length of the gripper 21. When the gripper 21 abuts against the side wall of the main shaft or mounting flange, the rollers 210 contact the side wall. During the movement of the gripper 21, the rollers 210 roll, achieving rolling contact with the side wall. The rollers 210 transform the sliding friction between the gripper 21 and the main shaft or flange side wall into rolling friction, significantly reducing friction and making the movement and positioning of the gripper 21 smoother, reducing wear and extending its service life. Multiple spaced rollers 210 further disperse the pressure between the gripper 21 and the side wall, avoiding excessive wear caused by excessive local pressure, while improving the stability and reliability of the contact between the gripper 21 and the side wall, ensuring the accuracy of positioning the spindle or flange.

[0050] The mobile trolley 51 adopts a frame structure with multiple casters installed at the bottom, allowing it to move on the ground. The second telescopic member 52 is fixedly installed on the upper surface of the mobile trolley 51, extending vertically. A support plate 6 is installed at the telescopic end of the second telescopic member 52. The third telescopic member 53 is installed on the support plate 6 via a bracket 7, extending horizontally and perpendicular to the telescopic direction of the second telescopic member 52. The partition plate 12 is fixedly connected to the telescopic end of the third telescopic member 53 by bolts or other means.

[0051] A turntable 54 is mounted on a mobile trolley 51, located below the second telescopic member 52, which is fixedly mounted on the upper surface of the turntable 54 via a base. A rotation drive 55 (such as a drive mechanism consisting of a motor and a reducer) is mounted on the mobile trolley 51, and its output shaft is connected to the turntable 54 to drive the turntable 54 to rotate around its axis. When the turntable 54 rotates, it drives the second telescopic member 52, the third telescopic member 53, the support plate 1, the limiting device 2, and the gripping device 3 to rotate together, thereby adjusting the orientation of the device.

[0052] The mobile trolley 51 and pulleys enable the device to move easily between different installation positions. The cooperation of the second telescopic component 52 and the third telescopic component 53 allows for vertical and horizontal position adjustment of the support plate 1, enabling adjustment of the relative position of the coupling and the main shaft to meet the needs of different installation heights and horizontal distances. The turntable 54 and the rotation drive component 55 allow the device to rotate at an angle on a horizontal plane. Even in installation environments with different angles, the orientation of the limiting device 2 and the gripping device 3 can be adjusted to ensure the coupling and the main shaft are at the appropriate installation angle, greatly improving the device's versatility and adaptability. The support plate 6 and the bracket 7 provide stable installation support for the third telescopic component 53, ensuring its stability during telescopic movement and guaranteeing the accuracy and reliability of the device's position adjustment, further improving the efficiency and quality of coupling installation. The bracket 7 consists of two bolted parts, allowing the third telescopic component 53 to be removed for easy maintenance.

[0053] In use, the drive mechanism of the gripper 31 in the gripping device 3 is activated. The drive mechanism drives at least three grippers 31 to move closer together and grip the outer peripheral wall of the coupling. During the gripping process, the symmetrical distribution and synchronous movement of the grippers 31 ensure that the center of the coupling coincides with the center of the support plate 1. Then, the moving trolley 51 is operated to move the entire device to a suitable position on the side of the main shaft of the coupling to be installed. The turntable 54 is rotated by rotating the drive component 55, so that the limiting device 2 and the gripping device 3 face the main shaft. At the same time, the position of the support plate 1 is adjusted in the vertical and horizontal directions using the second telescopic component 52 and the third telescopic component 53, so that the support plate 1 is roughly in a position that is easy to install. Then, the first telescopic component 24 is activated. The first telescopic component 24 extends, so that the main shaft or the mounting flange of the main shaft is located in the gripping space of the limiting device 2. The rotating plate 22 is rotated by the connecting rod 23, so that the multiple grippers 21 slide relative to each other along the slide rail on the support plate 1 and move closer together. Once one or more of the grippers 21 abut against the spindle or its mounting flange, the clamping space of the limiting device 2 is adjusted by adjusting the first telescopic member 24. Simultaneously, the extension / retraction of the second telescopic member 52 and the third telescopic member 53 is adjusted to ensure all grippers 21 abut against the spindle or its mounting flange. At this point, the center of the spindle coincides with that of the support plate 1, completing the spindle positioning. After confirming the position is correct, the extension / retraction of the third telescopic member 53 is adjusted, causing the support plate 1 to slide towards the spindle, moving the limiting device 2 and the gripping device 3, thus smoothly mounting the coupling onto the spindle and completing the coupling installation. During this process, the rollers 210 at the gripping end of the grippers 21 roll against the side wall of the spindle or flange, reducing friction and making the positioning operation smoother.

[0054] After installation, each component is reset sequentially. First, the first telescopic member 24 moves the grippers 21 apart from each other, disengaging them from the spindle or flange. Then, the grippers 31 of the gripping device 3 are controlled to release the coupling. Finally, the device is moved to the designated storage location by the trolley 51 for future use.
