Description

Technical Field

[0001] This application relates to the field of steel rolling technology, and in particular to an auxiliary tooling for disassembling and assembling a hydraulic pump outlet filter. Background Technology

[0002] Hydraulic systems are increasingly widely used in industry, particularly in the hot rolling process of steel production. To ensure the cleanliness of hydraulic systems, numerous filters are installed within them, including suction filters, pump outlet filters, circulation filters, return filters, and control oil filters. The filter elements of these filters need to be replaced periodically according to regulations. Hydraulic pump outlet filters, in particular, are characterized by high flow rates, high pressures, and high pressure differentials. The filters and filter elements are relatively heavy, making replacement difficult and posing certain safety risks.

[0003] Replacing the hydraulic pump outlet filter element requires disassembling and reassembling the filter cartridge or lower end cap. Because the filter cartridge is relatively thick and heavy, the disassembly and reassembly process is difficult. Replacing the filter element is even more challenging if the external hexagonal nut on the cartridge or lower end cap is damaged. Reinstalling the filter element requires multiple people working together: one person lifts the filter element and cartridge while another aligns the threads and then tightens them. Due to the weight, multiple alignments are often required before tightening, resulting in a heavy workload and low replacement efficiency for maintenance personnel. Utility Model Content

[0019] The auxiliary tooling in this application is used for the disassembly and assembly of a hydraulic pump outlet filter. The auxiliary tooling includes a main body and a working component. The main body is positioned below the hydraulic pump. The working component is rotatably connected to the main body in the middle. One end of the working component has a support seat that extends and supports the lower part of the filter. The other end of the working component has a constraint portion between it and the main body. When the filter is disassembled onto the support seat, the constraint portion restricts the working component from rotating on the main body. During the disassembly and assembly of the hydraulic pump outlet filter, the operating main body is positioned in the lower region of the hydraulic pump. By applying force to one end of the main body, the support seat extends to the bottom of the filter at the hydraulic pump outlet until it supports the filter. The filter is supported by a bracket, allowing workers to directly remove it. The bracket provides stable support for the entire filter element, eliminating the need for manual lifting during removal and ensuring operational safety and reducing workload. Furthermore, the bracket's restraint mechanism connects the working component to the main body, maintaining relative stability and resisting the filter's gravity, thus improving the overall reliability of the auxiliary tooling. Correspondingly, filter installation can be performed by pre-positioning the filter using the working component and bracket, allowing workers to connect and install it, increasing the efficiency of individual work and reducing operational difficulty and labor intensity.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0024] like Figure 1 As shown, Figure 1 This is a schematic diagram of the auxiliary tooling provided in an embodiment of this application. An auxiliary tooling for disassembling and assembling a hydraulic pump outlet filter 300 includes a main body 100 and a working part 200, wherein:

[0025] The main body 100 is positioned below the hydraulic pump and serves as the foundation for the auxiliary tooling. It is directly positioned in the lower area of ​​the hydraulic pump to provide a stable and reliable working base during the installation and removal of the filter 300, eliminating the influence of complex environmental factors within the work area. The main body 100 can be made of robust and durable materials, such as steel or aluminum alloy, to ensure stability under the weight of the filter 300 and the forces exerted during operation. The shape and dimensions of the main body 100 are determined based on the available space at the bottom of the hydraulic pump to provide a suitable fit and sufficient support.

[0026] like Figure 1 As shown, the working component 200 is rotatably connected to the main body 100 in the middle. One end of the working component 200 is provided with a support 201, which is used to extend and support the lower part of the filter 300. The other end of the working component 200 is provided with a constraint part 203 between it and the main body 100. When the filter 300 is disassembled onto the support 201, the constraint part 203 restricts the working component 200 from rotating on the main body 100.

[0027] The working component 200 is rotatably connected to the main body 100 via its middle section, allowing the working component 200 to be flexibly adjusted in position during operation to accommodate different sizes and shapes of the filter 300 and their relative working positions. One end of the working component 200 is provided with a support 201 for extending and supporting the lower part of the filter 300. The support 201 ensures stable support for the filter 300 during disassembly, preventing the filter 300 from slipping or being damaged during operation.

[0028] like Figure 1As shown, the restraint part 203 is arranged between the working part 200 and the main body 100 to prevent the working part 200 from rotating relative to the main body 100 due to the weight of the filter 300 when the filter 300 is disassembled onto the support 201. The function of the restraint part 203 is to ensure that the working part 200 will not rotate uncontrollably due to external forces after the filter 300 is placed on the support 201, thereby ensuring operational safety and the stability of the filter 300. The restraint part 203 can be implemented through various mechanisms, such as locking pins, buckles, or hydraulic locking systems, to adapt to different operating environments and requirements.

[0029] like Figure 1 As shown, during actual operation, the main body 100 is first placed under the hydraulic pump to ensure its stability and fit. The position and angle of the working piece 200 are adjusted beforehand according to the position and size of the filter 300, aligning the center of the filter 300 with the center of the support 201. The support 201 on the working piece 200 is then extended to the lower part of the filter 300 until it can support the filter 300, allowing for safe disassembly by a single person. Once the filter 300 is placed on the support 201, the corresponding constraint 203 is pulled by the working piece 200 and the main body 100, constraining the working piece 200 and preventing its rotation. After the filter 300 is safely placed on the support 201 and the working piece 200 is locked, subsequent maintenance or replacement work can proceed.

[0030] In an optional embodiment, the auxiliary tooling of this application is used for the disassembly and assembly of the hydraulic pump outlet filter 300. The working principle of the auxiliary tooling is as follows: the auxiliary tooling includes a main body 100 and a working part 200. The main body 100 is arranged at the lower part of the hydraulic pump. The working part 200 is rotatably connected to the main body 100 at its middle part. One end of the working part 200 is provided with a support 201, which extends and supports the lower part of the filter 300. The other end of the working part 200 is provided with a constraint part 203 between it and the main body 100. When the filter 300 is disassembled onto the support 201, the constraint part 203 restricts the working part 200 from rotating on the main body 100. During the disassembly and assembly of the hydraulic pump outlet filter 300, the main body 100 is positioned in the lower area of ​​the hydraulic pump. By applying force to one end of the main body 100 and causing the support 201 to extend... The filter 300 extends to the bottom of the hydraulic pump outlet, until the support 201 supports the filter 300. At this point, the operator can directly remove the filter 300. The support 201 forms a stable support for the entire filter element, and no manual lifting operation is required until the removal is completed, ensuring work safety and reducing work intensity. During the process of the support 201 supporting the filter 300, the restraint part 203 is connected to the working part 200 and the main body 100 to maintain the relative stability of the working part 200. The restraint part 203 restricts the connection and resists the gravity of the filter 300, improving the reliability of the overall auxiliary tooling. Correspondingly, the installation of the filter 300 can also be carried out in advance by the working part 200 and the support 201 holding the filter 300 in a pre-installation position, and then the operator can carry out the installation and connection operation, improving the effectiveness of the operator's individual operation and reducing the difficulty and labor intensity of the operation.

[0031] like Figure 1 As shown, in an optional embodiment, a lifting member is provided between the working component 200 and the support 201 to drive the support 201 to move up and down on the working component 200.

[0032] The lifting component allows the support 201 to move up and down on the working part 200 to accommodate filters 300 at different heights. This enables the auxiliary tooling to accommodate hydraulic pump filters 300 of different models and sizes, increasing the versatility and applicability of the auxiliary tooling.

[0033] like Figure 1As shown, in an optional embodiment, the lifting member includes an adjusting screw 204, one end of which passes through the working member 200 and is fixedly connected to the support 201. The adjusting screw 204 passes through the working member 200 and has a threaded section that is threaded to the working member 200.

[0034] The adjusting screw 204 is used to achieve precise lifting and lowering of the support 201. One end of the adjusting screw 204 passes through the working part 200 and is fixedly connected to the support 201 to ensure the stability of the support 201 during lifting and lowering. The threaded section on the adjusting screw 204 engages with the threaded section on the working part 200. By rotating the adjusting screw 204, the support 201 can be moved up and down.

[0035] like Figure 1 As shown, in an optional embodiment, the lifting member further includes a base 205 fixedly mounted on the working member 200, the adjusting screw 204 passing through the base 205, and the adjusting screw 204 having a guide section that slides with the base 205.

[0036] The lifting component also includes a base 205 fixed to the working component 200. The base 205 provides stable support for the adjusting screw 204 and ensures the guidance of the adjusting screw 204 during lifting. The adjusting screw 204 passes through the base 205 and has a guide section that slides with the base 205 to allow the adjusting screw 204 to slide freely within the base 205 while maintaining precise guidance.

[0037] This makes the operation of the auxiliary tooling more flexible and precise, improves the adaptability and practicality of the auxiliary tooling, and makes the disassembly and assembly of the filter 300 more efficient and safer.

[0038] like Figure 1 As shown, in an optional embodiment, the support 201 is provided with a receiving groove 202 with a top opening. This receiving groove 202 is used to accommodate the bottom area of ​​the filter 300, which not only protects the top of the adjusting screw 204 from damage, but also provides an interface area for conveniently fixing the filter element, so that the operator can connect the filter element more stably.

[0039] In an optional embodiment, the main body 100 is provided with a connecting pin 102, which passes through the middle of the working part 200.

[0040] like Figure 1As shown, the connecting pin 102 is used to movably fix the workpiece 200 to the main body 100. This allows the workpiece 200 to remain stable on the main body 100, while allowing necessary rotation to adapt to different operational needs. The connecting pin 102 passes through the middle of the workpiece 200, ensuring both the fixation of the workpiece 200 on the main body 100 and the flexibility of operation.

[0041] like Figure 1 As shown, in an optional embodiment, the main body 100 is provided with at least two sets of mounting positions 103 located at different heights, and the connecting pin 102 is fixed on one set of mounting positions so that the working part 200 is connected to the main body 100 at different heights.

[0042] The main body 100 is provided with at least two sets of mounting positions 103 located at different heights. These mounting positions 103 allow the connecting pin 102 to be fixed in different positions, thereby enabling the working part 200 to be connected at different heights of the main body 100. This allows the auxiliary tooling to adapt to hydraulic pumps and filters 300 at different heights, increasing the versatility and applicability of the auxiliary tooling.

[0043] like Figure 1 As shown, in an optional embodiment, the constraint part 203 is a tensile spring. The constraint part 203 uses a tensile spring. The tensile properties of the spring restrict the rotation of the working part 200 on the main body 100. When the filter 300 is placed on the support 201, the tensile spring automatically applies a certain resistance to prevent accidental rotation of the working part 200. This provides a stable constraint force without increasing complexity.

[0044] In an optional embodiment, the restraint part 203 is a tension rope. The tension rope restraint part 203 restricts the rotation of the workpiece 200 through the tension of the rope. The tension rope can be easily adjusted to adapt to different operational needs and the weight of the filter 300. The flexibility of the rope also allows for quick release of the restraint when needed, facilitating rapid operation.

[0045] like Figure 1 As shown, in an optional embodiment, the working component 200 is made of rigid square tubing, which provides high strength and stability, enabling it to withstand significant weight and operating forces. The rigid square tubing also makes the working component 200 more robust and durable, suitable for long-term use in industrial environments. Furthermore, the square tubing shape facilitates the design and installation of various auxiliary components, such as lifting components and restraint parts 203, meeting the specific needs of different users in different environments and improving the practicality and efficiency of the auxiliary tooling.
