Description

Technical Field

[0001] This utility model belongs to the field of seawater desalination engineering technology, and in particular relates to a hoisting tool for a hydraulic cylinder port assembly. Background Technology

[0002] In the field of energy recovery technology, hydraulic cylinder energy recovery systems often use shell port assemblies as key connection structures. These assemblies are usually made of high-strength alloy materials to meet the requirements of high-pressure sealing and long-term operation, resulting in a single component weight generally exceeding 100 kg. In the current installation process, workers need to rely on manual handling or use general lifting tools to align the port assembly with the cylinder slot for assembly. However, due to the complex shape and structure of the port assembly and the strict assembly requirements with the internal groove of the cylinder, general lifting tools are difficult to achieve precise positioning. During operation, multiple workers often need to repeatedly adjust the angle of the assembly, which is not only inefficient but also poses a risk of component slippage. In addition, the operating space inside the cylinder is narrow, and the lifting point position of the general lifting tool is fixed, which cannot adapt to the spatial misalignment between the center of gravity of the port assembly and the internal groove of the cylinder, often resulting in the port assembly getting stuck or the sealing surface being damaged. Furthermore, the industry has developed specialized lifting tools, which usually use temporary lifting lugs to assist in installation, but this method will damage the protective layer on the surface of the assembly, and the lifting lugs need to be re-welded and ground after removal, increasing additional costs. Utility Model Content

[0003] In view of this, the present invention aims to provide a hoisting tool for hydraulic cylinder port assembly, so as to solve the problems of the hydraulic cylinder port assembly being heavy, unable to be inserted into the cylinder body by manpower, and lacking a dedicated hoisting tool.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting fixture for a hydraulic cylinder port assembly, comprising a fixed plate, C-shaped side plates, an adjusting plate, and a lifting ring. One end of the C-shaped side plate is a fixed end, and the other end is a suspended end. The width of the fixed end is greater than the width of the suspended end. The suspended end and the fixed end are vertically offset, with the suspended end located above the fixed end and extending outward. There are two C-shaped side plates, spaced apart. The fixed ends of the two C-shaped side plates are vertically connected to one side of the fixed plate. The adjusting plate is connected between the suspended ends of the two C-shaped side plates. The adjusting plate is provided with multiple through threaded holes, and the lifting ring is detachably disposed within the through threaded holes of the adjusting plate.

[0005] Furthermore, the fixing plate is a square plate with a round hole in the middle, and bolts are provided at all four corners of the fixing plate.

[0006] Furthermore, at least one reinforcing plate is provided between the two C-shaped side plates, and the two ends of the reinforcing plate are welded to the inner surfaces of the two C-shaped side plates.

[0007] Furthermore, a screw is welded to the bottom of the lifting ring, and the lifting ring is set in a through threaded hole on the adjusting plate through the screw.

[0008] Furthermore, the fixed end of the C-shaped side plate is welded to the fixed plate.

[0009] Furthermore, the screw is equipped with an anti-loosening nut, which is located below the adjusting plate.

[0010] Furthermore, the bolts are installed through the fixing plate.

[0011] Furthermore, the reinforcing plate is disposed in the area between the fixed end and the suspended end of the C-shaped side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model can be used for hoisting various energy recovery shell port components. By setting two spaced C-shaped side plates and vertically connecting a fixing plate to their fixed ends, the bolts at the four corners of the fixing plate can connect the hoisting fixture to the port component, ensuring that the port component and the hoisting fixture are firmly connected during the hoisting process. The adjustment plate is set at the suspension end of the C-shaped side plate, so that the hoisting point is located above the component, and it can be directly hoisted by lifting equipment. This overcomes the problem that the port component is too heavy to be moved manually and inserted into the cylinder, and significantly improves the safety and efficiency of hoisting operations.

[0014] 2. The adjustment plate of this utility model is provided with multiple through threaded holes. A screw is welded to the bottom of the lifting ring and screwed into the threaded hole of the adjustment plate. The installation position of the lifting ring can be flexibly adjusted according to actual needs and the center of gravity of the port assembly, so that the end face of the port assembly is parallel to the end face of the shell, avoiding the problem of the port assembly getting stuck and causing damage to the sealing surface. At the same time, an anti-loosening nut is provided on the screw, which enhances the reliability of the lifting ring connection and effectively prevents the risk of the lifting ring accidentally loosening due to vibration or impact during the lifting process, further ensuring the safety of the lifting operation.

[0015] 3. The fixed end of the C-shaped side wall panel of this utility model is wider than the suspended end, and the suspended end is located above the fixed end and extends outward, so that when the tooling is installed on the housing port assembly, the suspended end can effectively avoid interference from the cylinder port, providing the necessary space for hoisting operations.

[0016] 4. This utility model has a reinforcing plate between the two C-shaped side plates, which is welded to the inner side of the C-shaped side plates to form a stable support frame. This significantly enhances the rigidity and deformation resistance of the hoisting fixture, especially when subjected to heavy loads, it can effectively prevent the side plates from twisting or becoming unstable, and further improve the stability of the hoisting fixture structure.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0032] Detailed implementation method: See Figure 1-11 This embodiment describes a hoisting fixture for a hydraulic cylinder port assembly. It includes a fixed plate 1-1, C-shaped side plates 1-2, an adjusting plate 1-4, and a lifting ring 1-5. One end of the C-shaped side plate 1-2 is a fixed end, and the other end is a suspended end. The width of the fixed end is greater than the width of the suspended end. The suspended end and the fixed end are vertically offset, allowing the suspended end to effectively avoid interference with the cylinder port when the fixture is installed on the housing port assembly, providing necessary space for hoisting operations. The suspended end is located above the fixed end and extends outward. There are two C-shaped side plates 1-2, spaced apart. The C-shaped side plates 1-2 transfer the hoisting load to the fixed plate and can adapt to the shape and installation position of the energy recovery housing port assembly during hoisting. The two C-shaped side plates 1-2 are vertically connected to one side of the fixing plate 1-1, and the other side of the fixing plate 1-1 is connected to the end face of the port assembly 2. The fixing plate 1-1 serves as the mounting base for the hoisting fixture 1 and the port assembly 2, providing a stable support surface and ensuring uniform force distribution during hoisting. The adjusting plate 1-4 is connected between the suspension ends of the two C-shaped side plates 1-2. The adjusting plate 1-4 is provided with multiple through threaded holes. The lifting ring 1-5 is detachably installed in the through threaded holes of the adjusting plate 1-4. The adjusting plate 1-4 provides an adjustable lifting point position for the hoisting, thereby adapting to the balanced hoisting requirements of port assemblies 2 of different weights. The lifting ring 1-5 serves as the connection point of the crane hook and directly bears the hoisting load.

[0033] The working principle of this utility model is as follows:

[0034] Connect the fixing plate 1-1 to the end face of the energy recovery housing port assembly. Based on the center of gravity of the energy recovery housing port assembly, select the through threaded hole on the adjusting plate 1-4. Connect the crane hook to the lifting ring 1-5. Lift the energy recovery housing port assembly off the ground using the lifting fixture 1. At this point, observe whether the end face of the energy recovery housing port assembly is parallel to the end face of the energy recovery housing. If not, lower the energy recovery housing port assembly back to the ground. Adjust the position of the lifting ring 1-5 in the through threaded hole on the adjusting plate 1-4 as needed, and lift it again. After confirming that the end face of the energy recovery housing port assembly is parallel to the end face of the energy recovery housing, install the energy recovery housing port assembly into the energy recovery housing.

[0035] The fixing plate 1-1 is a square plate with a round hole in the middle. The diameter of the round hole is larger than the outer diameter of the interface 2-1, so as to provide a through channel for the interface 2-1 and ensure that the installation is not obstructed by the interface 2-1. At the same time, it ensures that the threaded hole on the end face of the fixing plate 1-1 is aligned with the end face of the sealing component 2-2, and ensures that the fixing plate 1-1 is installed in the center. Bolts 1-6 are provided at the four corners of the fixing plate 1-1, and the fixing plate 1-1 is connected to the end face of the sealing component through the bolts 1-6.

[0036] At least one reinforcing plate 1-3 is provided between the two C-shaped side plates 1-2. The two ends of the reinforcing plate 1-3 are welded to the inner surfaces of the two C-shaped side plates 1-2. The load of the reinforcing plate 1-3 is directly transferred to the C-shaped side plates 1-2 through the inner welding, thereby reducing local deformation.

[0037] The bottom of the lifting ring 1-5 is welded with a screw rod. The lifting ring 1-5 is set in the through threaded hole on the adjusting plate 1-4 through the screw rod. When it is necessary to adjust the position of the lifting ring 1-5, it can be disassembled by simply turning the lifting ring 1-5.

[0038] The fixed end of the C-shaped side plate 1-2 is welded to the fixed plate 1-1 to ensure that there is no relative displacement between the C-shaped side plate 1-2 and the fixed plate 1-1, thus maintaining the accuracy of the spatial position of the suspension end.

[0039] The screw is equipped with an anti-loosening nut, which is located below the adjusting plates 1-4. When the crane stops suddenly or shakes, the threads may loosen in the opposite direction. The anti-loosening nut forms an anti-loosening structure to prevent the lifting ring from loosening during hoisting and affecting the safety of use.

[0040] The bolts 1-6 are installed through the fixing plate 1-1. The connection of bolts 1-6 allows the lifting fixture 1 to be separated from the port assembly 2, which facilitates the replacement of damaged parts.

[0041] The reinforcing plate 1-3 is set in the area between the fixed end and the suspended end of the C-shaped side plate 1-2 to ensure that the tooling is not deformed when the port assembly 2 is suspended, extend the tooling life, and avoid fatigue cracking of the C-shaped side plate 1-2 caused by repeated hoisting.

[0042] See Figure 4-11 To illustrate the working principle of this utility model, let's take the hoisting of the hydraulic cylinder port assembly as an example:

[0043] Assemble the interface 2-1 of port assembly 2 with the sealing assembly 2-1. Fix the fixing plate 1-1 to the end face of the sealing assembly 2-1 with bolts 1-6. After connecting the lifting ring 1-5 to the threaded hole of the adjusting plate 1-4, install the anti-loosening nut. Connect the crane hook to the lifting ring 1-5. Lift the port assembly 2 off the ground using the lifting fixture 1. At this time, observe whether the end face of the port assembly 2 is parallel to the end face of the cylinder 3. If not, lower the port assembly 2 back to the ground and readjust the position of the lifting ring 1-5 on the adjusting plate 1-4 until the end face of the port assembly 2 is parallel to the end face of the cylinder 3 when lifted. Use a crane to lift the port assembly 2 into the cylinder 3 and fix it manually to complete the installation.

[0044] The specific embodiments of this utility model disclosed above are merely illustrative of the present utility model. These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
