Description

Technical Field

[0001] This utility model relates to the field of lifting ring installation technology, and in particular to a lifting ring assembly tool. Background Technology

[0002] In many fields of mechanical engineering, the piston rod, as a key transmission or support component, often needs to be installed in conjunction with a lifting ring to achieve important functions such as lifting and connection. In crane equipment, the piston rod is used to drive the extension and retraction of the boom, while the lifting ring is the key node connecting the lifting rope and the boom, ensuring that heavy objects can be lifted safely and smoothly. In hydraulic equipment, the movement of the piston rod also often works in coordination with other components through connectors such as lifting rings to complete various complex mechanical actions.

[0003] Traditionally, installing lifting rings on piston rods relies heavily on manual operation. Manual operation makes it difficult to ensure the precise positioning of the lifting ring and piston rod, easily leading to problems such as misaligned installation and inaccurate matching with the grooves on the piston rod. This not only affects the overall aesthetics of the equipment and increases the risk of component wear and even damage, but also, current common disassembly methods mostly involve using general-purpose tools such as pry bars and hammers to directly disassemble the lifting ring or piston rod. This method is not only inconvenient to operate, but also makes it difficult for operators to control the magnitude and direction of force, easily causing irreversible damage such as scratches and deformation to the surface of the lifting ring and piston rod, affecting the reusability and lifespan of the components.

[0004] In view of the above-mentioned problems existing in the prior art, there is an urgent need for a lifting ring assembly tool to solve the above problems. Utility Model Content

A sliding nut is threaded onto the upper part of the lead screw. Multiple mounting blocks are evenly spaced along the circumferential direction on the surface of the sliding nut. Fastening clamps are movably mounted on the bottom of each mounting block. The assembly assembly is used to snap the lifting ring onto the piston rod.

[0008] A further preferred embodiment is that the bottom of the lead screw is provided with a fastening groove that matches the size of the top of the piston rod.

[0009] Further preferably, the installation assembly further comprises a short sleeve, a tapered sleeve, an installation ring and a copper rod, the tapered sleeve is connected to the top end of the piston rod, the ring is sleeved on the outer wall of the tapered sleeve, and the installation assembly is used for sleeving the ring on the piston rod.

[0010] Further preferably, the bottom end of the short sleeve is connected to the tapered sleeve, and the short sleeve is used for knocking the ring sleeved on the tapered sleeve to the clamping groove position on the piston rod.

[0022] The following will be combined with the accompanying Figures 1 to 6 The utility model is further introduced in detail.

[0023] A lifting ring assembly tool, as shown in Figure 1 and Figure 6 It is used for installing the lifting ring 4 on the piston rod 3, comprising two mutually symmetrical recess covers 10, further, the recess cover 10 is fastened to the lifting ring 4 installed on the piston rod 3 through the vice, and further comprising:

[0024] The assembly assembly comprises a screw rod 5, a sliding nut 6, a mounting block 7 and a fastening clamp 8, the top end of the screw rod 5 is clamped at the top end of the piston rod 3, the sliding nut 6 is screw-mounted on the upper portion of the screw rod 5, three mounting blocks 7 are installed on the surface of the sliding nut 6 along the circumferential direction at equal intervals, and the bottom of the three mounting blocks 7 is movably installed with the fastening clamp 8, and the assembly assembly is used for clamping the lifting ring 4 on the piston rod 3.

[0025] The cooperation of the lead screw 5, the sliding nut 6, the mounting block 7 and the fastening clamp 8 can accurately clamp the lifting ring 4 on the piston rod 3 in use. The top end of the lead screw 5 is clamped with the top end of the piston rod 3, the sliding nut 6 can be flexibly moved on the lead screw 5 to adjust the position, the fastening clamp 8 at the bottom of the multiple mounting blocks 7 installed at equal intervals in the circumferential direction can fix the lifting ring 4 from multiple angles, so that the installation position of the lifting ring 4 is accurate, and the positional deviation in manual installation is avoided, and the installation efficiency is effectively improved; the design of the long sleeve 9, the dismounting pliers and the copper rod in the dismounting assembly makes the lifting ring 4 convenient to separate from the piston rod 3, the long sleeve 9 is clamped at the top end of the piston rod 3 and abuts against the lifting ring 4, and then the dismounting pliers and the copper rod are used to knock the long sleeve 9, which can effectively overcome the connecting force between the lifting ring 4 and the piston rod 3, and smoothly realize the dismounting of the lifting ring 4; when the lifting ring 4 is dismounted, the long sleeve 9 serves as a transmission component of the knocking force of the copper rod, and can uniformly transmit the force to the lifting ring 4, avoiding local excessive force and deformation, scratches and other damages caused by directly knocking the lifting ring 4; the reasonable cooperation of the short sleeve 1, the conical sleeve 2 and the piston rod 3 in the installation process can also prevent damage such as knocking and scratching on the surface of the piston rod 3, prolong the service life of the components and reduce the maintenance and replacement cost.

[0026] Specifically, as shown in Figure 1 The bottom of the lead screw 5 is provided with a fastening groove matched in size with the top of the piston rod 3, which further improves the stability of the clamping of the lead screw 5 and the clamping efficiency of the lifting ring 4 when the lifting ring 4 is clamped on the piston rod 3.

[0027] Specifically, as shown in Figure 3 and Figure 4 The installation assembly includes a short sleeve 1, a conical sleeve 2, a lifting ring 4 and a copper rod, the conical sleeve 2 is clamped at the top end of the piston rod 3, the lifting ring 4 is sleeved on the outer side wall of the conical sleeve 2, and the installation assembly is used to sleeve the lifting ring 4 on the piston rod 3. When in use, the conical sleeve 2 is first clamped at the top end of the piston rod 3, then the lifting ring 4 is sleeved on the outer side wall of the conical sleeve 2, the short sleeve 1 is sleeved on the conical sleeve 2, and finally the copper rod is used to knock the short sleeve 1, so that the lifting ring 4 is sleeved on the piston rod 3, and the installation of the lifting ring 4 is convenient and fast.

[0028] Specifically, the bottom end of the short sleeve 1 is clamped on the conical sleeve 2, and the short sleeve 1 is used to knock the lifting ring 4 sleeved on the conical sleeve 2 to the clamping groove position on the piston rod 3. Further, the bottom end of the short sleeve 1 is clamped on the conical sleeve 2, so that the short sleeve 1 and the conical sleeve 2 form a relatively stable overall structure. In turn, when the top of the short sleeve 1 is knocked, the force direction transmitted to the lifting ring 4 can be relatively accurately along the axial direction of the conical sleeve 2, thereby guiding the lifting ring 4 to accurately move towards the clamping groove position on the piston rod 3, thereby effectively avoiding the position deviation of the lifting ring 4 during installation, ensuring that the lifting ring 4 can be accurately installed to the predetermined clamping groove position, and ensuring the accuracy of the installation position of the entire lifting ring 4.

[0029] Specifically, the disassembly assembly includes a long sleeve 9, a dismounting clamp and a copper bar. The long sleeve 9 is clamped on the top end of the piston rod 3, and the bottom of the long sleeve 9 abuts against the lifting ring 4. The disassembly assembly is used to separate the lifting ring 4 from the piston rod 3. Further, the long sleeve 9 is clamped on the top end of the piston rod 3, and the bottom of the long sleeve 9 abuts against the lifting ring 4. In turn, when the dismounting clamp is used in cooperation with the copper bar for dismounting work, the operator can more conveniently apply force, thereby reducing the operation difficulty and making the entire dismounting work easier to operate.

[0030] Specifically, the bottom of the short sleeve 1, the conical sleeve 2 and the long sleeve 9 are all provided with cavities which are sized to be matched with the top of the piston rod 3. When the cavities at the bottom of the short sleeve 1, the conical sleeve 2 and the long sleeve 9 are sized to be matched with the top of the piston rod 3, the short sleeve 1 can be tightly clamped on the piston rod 3, and there is almost no excess gap between them. When the lifting ring 7 is installed or dismounted, the short sleeve 1 will not easily shake or shift relative to the piston rod 3.

[0031] Specifically, the copper bar knocks the top of the short sleeve 1 and the long sleeve 9, respectively.

[0032] Working principle

[0033] In use, first, the conical sleeve 2 is clamped on the top end of the piston rod 3. Then, the lifting ring 4 is sleeved on the outer wall of the conical sleeve 2, and the short sleeve 1 is sleeved on the conical sleeve 2. Finally, the copper bar is used to knock the short sleeve 1, so that the lifting ring 4 is sleeved on the piston rod 3. Subsequently, the piston rod 3 and the lifting ring 4 are placed between the two groove covers 10, and the old tiger clamp is used to tighten the lifting ring 4, so that the lifting ring 4 is sleeved on the piston rod 3. At this time, the lead screw 5 is clamped on the top of the piston rod 3, and the three fastening clamps 8 are clamped on the lifting ring 4. The lead screw 5 is rotated, so that the sliding nut 6 drives the fastening clamp 8 to move upward through the mounting block 7, thereby the fastening clamp 8 drives the lifting ring 4 to knock to the clamping groove position on the piston rod 3, and the installation of the lifting ring 4 is realized.

[0034] When the lifting ring 4 is removed, first, the long sleeve 9 is clamped at the top end of the piston rod 3, and the bottom is in contact with the lifting ring 4. At this time, the top of the long sleeve 9 is knocked by a copper rod, so that the long sleeve 9 separates the lifting ring 4 from the piston rod 3. Finally, the dismounting pliers are clamped at the notch position of the lifting ring 4, and the dismounting pliers are pulled to remove the lifting ring 4, so that the purpose of removing the lifting ring 4 is achieved.

[0035] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution according to the needs after reading the specification, but as long as the modifications are within the protection scope of the utility model, they are protected by the patent law.
