Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic support auxiliary equipment, specifically, to a multi-channel block for inlet and outlet fluids in an integrally forged hydraulic support. Background Technology

[0002] The inlet and return fluid multi-way block serves as a bridge connecting the power pipelines of the hydraulic supports in fully mechanized coal mining faces. Generally, inlet and return fluid multi-way blocks for hydraulic supports are either integrally machined or separately welded structures. Integral machined multi-way blocks involve a large amount of machining and have a low tolerance for machining errors during actual production. Sometimes, to meet functional requirements, the overall size and weight of the multi-way block need to be increased, significantly increasing the overall cost. Separately welded multi-way blocks are mostly made of ordinary carbon steel, which is not corrosion-resistant and has poor reliability. Stainless steel, being corrosion-resistant, is gradually gaining popularity. However, stainless steel is not suitable for separately welded multi-way blocks as it cannot meet market requirements. This is because stainless steel has high requirements for the quality of welds at the joints, and its welding performance is poor. Hydraulic support multi-way blocks are typically used to handle high-pressure fluids of 20-47 MPa; any welding defects will inevitably lead to leakage and failure of the multi-way block. Furthermore, from a structural perspective, such as... Figure 1 and Figure 2 As shown, for ease of processing, the inlet and outlet multi-channel blocks of both integral processing structure and split welding structure are mostly square structures, which occupy a large installation space. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an integral forged hydraulic support inlet and outlet multi-way block. This block is primarily used to connect high-pressure pipelines between hydraulic supports in fully mechanized coal mining faces, providing power support for various hydraulic support movements. It fully utilizes the technical advantages of forging, ensuring the multi-way block's functionality while using minimal material to reduce its size and weight, thereby lowering processing costs and improving material utilization. This meets market requirements for material quality, features a more refined and compact structure, and occupies less installation space during actual use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an inlet and return fluid multi-channel block for an integral forged hydraulic support, comprising an inlet and return fluid multi-channel block body, wherein the inlet and return fluid multi-channel block body is generally gourd-shaped, and the inlet and return fluid multi-channel block body comprises an upper small block and a lower large block integrally forged and formed, wherein the upper small block and the lower large block are both fan-shaped blocks that expand upwards and contract downwards.

[0005] Based on the above, inter-shelf return interfaces are symmetrically arranged on the left and right inclined end faces of the upper small block, and an internal return interface is arranged on the top of the upper small block. The inter-shelf return interfaces and the internal return interfaces on both sides are respectively connected to each other.

[0006] The lower large block has symmetrically arranged inter-rack liquid inlet and inter-rack water pipe inlets on its left and right inclined end faces, with vertical spacing between them. The upper front of the lower large block has an internal liquid inlet, and the bottom of the lower large block has an internal water pipe inlet. The inter-rack liquid inlet and internal liquid inlet on both sides are respectively connected to each other, and the inter-rack water pipe inlet and internal water pipe inlet on both sides are respectively connected to each other.

[0007] Based on the above, the main body of the inlet and outlet liquid multi-channel block is provided with several mounting holes.

[0008] Based on the above, the left and right inclined end faces of the upper small block correspond one-to-one with the left and right inclined end faces of the lower large block.

[0009] This utility model possesses outstanding substantive features and significant advancements compared to existing technologies. Specifically, the main body of the fluid inlet and return multi-channel block of this utility model is integrally forged. Compared to integrally machined structures and separately welded structures, this integrally forged fluid inlet and return multi-channel block exhibits better mechanical properties due to the characteristics of the forging process. Stainless steel can also be used for forging without processing defects, resulting in higher reliability when handling high-pressure liquids and meeting market requirements for material usage. Furthermore, from a machining perspective, forgings involve relatively less metal cutting, lower processing costs, and higher material utilization, ensuring the functionality of the multi-channel block while using as little material as possible to minimize its volume and weight. Structurally, this integrally forged fluid inlet and return multi-channel block is gourd-shaped, comprising an integrally formed upper small block and a lower large block. Both the upper small block and the lower large block are fan-shaped blocks that expand upwards and contract downwards. This design results in a more refined and compact structure, occupying less installation space during actual use. The integrally forged inlet and outlet fluid multi-pass block can also be designed into different shapes according to actual working conditions, making its design and use quite flexible.

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0016] like Figure 3 and Figure 4 As shown, an integral forged hydraulic support inlet and return fluid multi-channel block includes an inlet and return fluid multi-channel block body. The inlet and return fluid multi-channel block body is generally gourd-shaped and is integrally forged. It includes an integrally formed upper small block 1 and lower large block 2. Both the upper small block 1 and the lower large block 2 are fan-shaped blocks that expand upwards and contract downwards.

[0017] Compared to integrally machined and separately welded inlet / return multi-way blocks, this integrally forged inlet / return multi-way block boasts superior mechanical properties thanks to the characteristics of the forging process. Stainless steel can also be forged without machining defects, resulting in higher reliability under high-pressure liquid flow and meeting market requirements for material usage. Furthermore, from a machining perspective, forgings involve less metal removal, lower processing costs, and higher material utilization, ensuring functionality while minimizing material usage and reducing the block's size and weight. Structurally, this integrally forged inlet / return multi-way block is more refined and compact, occupying less installation space in practical applications.

[0018] Specifically, inter-shelf return interfaces 3 are symmetrically arranged on the left and right inclined end faces of the upper small block 1, and an internal return interface 4 is arranged on the top of the upper small block 1. The inter-shelf return interfaces 3 and the internal return interfaces 4 on both sides are respectively connected to each other.

[0019] The lower large block 2 has symmetrically arranged inter-rack liquid inlet ports 5 and inter-rack water pipe ports 6 on its left and right inclined end faces, respectively, spaced vertically. The upper front of the lower large block 2 has an internal liquid inlet port 7, and the bottom of the lower large block 2 has an internal water pipe port 8. The inter-rack liquid inlet ports 5 and internal liquid inlet ports 7 on both sides are connected to each other in a one-to-one correspondence. The inter-rack water pipe ports 6 and internal water pipe ports 8 on both sides are connected to each other in a one-to-one correspondence.

[0020] The main body of the inlet and outlet liquid multi-channel block is provided with several mounting holes 9.

[0021] In this embodiment, when the inlet and return fluid multi-channel block is in use, the main body of the inlet and return fluid multi-channel block can be fixed to the hydraulic support through each of the mounting holes 9. The high-pressure hose for inter-support return fluid is connected to the main body of the inlet and return fluid multi-channel block through the inter-support return fluid interface 3. The high-pressure hose for inter-support inlet fluid is connected to the main body of the inlet and return fluid multi-channel block through the inter-support inlet fluid interface 5. The inter-support inlet water pipe is connected to the main body of the inlet and return fluid multi-channel block through the inter-support water pipe interface 6. The main body of the inlet and return fluid multi-channel block then supplies fluid to the hydraulic support through the internal return fluid interface 4, the internal inlet fluid interface 7, and the internal water pipe interface 8.

[0022] The left and right inclined end faces of the upper small block 1 correspond parallel to the left and right inclined end faces of the lower large block 2. This makes it easier to connect the corresponding hoses and ensures that the hoses are arranged neatly.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
