Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mining electrical equipment, and in particular to an industrial control equipment dismounting structure and an industrial control equipment assembly. BACKGROUND

[0002] At present, the industrial control equipment on the market generally generates a large amount of heat during work, and therefore needs to be cooled in time to avoid the accumulation of heat affecting the stability of the normal working state of the industrial control equipment and the problem of greatly reducing the service life of the components of the industrial control equipment due to the continuous work of the components in a high-temperature environment. Figure 1 As a high-power mining frequency converter 01 of the industrial control equipment, an aluminum plate 02 is generally arranged between the radiator 03 of the explosion-proof cabinet and the frequency converter, thereby playing a transition role. By arranging the aluminum plate 02, the frequency converter 01 can be arranged as a whole structure in the explosion-proof cabinet. In order to ensure that the aluminum plate 02 is closely attached to the radiator 03, a whole surface of the aluminum plate 02 is generally coated with thermal conductive silicone grease, which can not only reduce the gap between the aluminum plate 02 and the radiator 03, but also stably transfer the heat generated by the frequency converter 01 during work to the radiator and dissipate the heat to the outside through the radiator 03. In the current scheme, in order to meet the connection and fixation between the frequency converter 01 and the radiator 03, a plurality of through holes are generally formed in the aluminum plate 02, and the screws are passed through the through holes and locked on the radiator 03, so as to fix the frequency converter 01 together with the aluminum plate 02 on the radiator 03. This way has the following problems:

[0003] 1. The overall weight of the mining frequency converter 01 exceeds 30 kg, and one person needs to hold the frequency converter 01 during installation, align the hole positions of the aluminum plate 02 and the radiator 03, and then the other person needs to tighten the screws for fixation. This operation method is extremely inconvenient. At the same time, in order to save the overall production cost, the space inside the explosion-proof cabinet is small and difficult to accommodate two people to work at the same time, which brings great difficulty to the dismounting of the equipment.

[0004] 2. After the aluminum plate 02 and the radiator 03 are attached, the thermal conductive silicone grease will mutually adsorb the aluminum plate 02 and the radiator 03. When the frequency converter 01 needs to be dismounted, due to the adsorption force generated by the thermal conductive silicone grease, the dismounting of the frequency converter 01 becomes extremely difficult, and the frequency converter 01 and the radiator 03 can only be separated by relying on brute force, which brings great inconvenience to the maintenance work and seriously affects the maintenance efficiency and convenience.

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0043] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For purposes of simplicity of the present disclosure, the following description will refer to specific examples of components and arrangements of components. It is understood, however, that these are only examples and are not intended to limit the present application in any way. Furthermore, the present application can be used in any number of different examples, many of which have been discussed. These are described in detail below.

[0044] For purposes of the description hereinafter, the terms "upper", "lower", "right", "left", "rear", "front", "vertical" and "horizontal" as can be perceived from the drawings are used for convenience only. The present application can assume various alternative orientations, except where otherwise indicated, and terms should be construed accordingly.

[0045] In order to solve the technical problems of inconvenient operation, low efficiency and difficulty in disassembly caused by adsorption of heat-conducting silicone grease in the process of installation, disassembly and maintenance of the mine frequency converter in the prior art, the application provides an industrial control equipment dismounting structure and an industrial control equipment assembly, which can ensure the heat dissipation performance of the industrial control equipment is not affected, effectively solve the installation and disassembly problems caused by the large weight of the equipment, the narrow installation space and the adsorption effect of the heat-conducting silicone grease, realize that a single person can easily and conveniently complete the installation and disassembly operation of the industrial control equipment in a cramped space, fully meet the use requirements in a high-vibration environment, greatly improve the convenience and efficiency of the installation, disassembly and maintenance of the industrial control equipment, improve the practicability and stability of the equipment as a whole, and provide more reliable technical support for the use and maintenance of the industrial control equipment.

[0046] In the first aspect, refer to Figure 2 , Figure 3 and Figure 4The application provides a dismounting structure of an industrial control device, which comprises a pressing block assembly 1 for fixing a heat-conducting plate 21 of the industrial control device on a radiator 3, the pressing block assembly 1 is arranged on the opposite two ends of the heat-conducting plate 21 respectively, the pressing block assembly 1 comprises a flat plate pressing block 11 arranged on the radiator 3 and a wedge-shaped pressing block 12 movably arranged on the flat plate pressing block 11, one end of the wedge-shaped pressing block 12 is provided with a first inclined surface 121, and the wedge-shaped pressing block 12 at the two ends is fixed on the flat plate pressing block 11 by applying force to the heat-conducting plate 21 in the direction of the radiator 3 and the center of the heat-conducting plate 21 through the first inclined surface 121.

[0047] In the embodiments provided in the application, the frequency converter 2 is taken as the industrial control device, the frequency converter 2 is arranged on the heat-conducting plate 21, and the pressing block assembly 1 is arranged on the radiator 3 at the positions corresponding to the two ends of the heat-conducting plate 21. When the frequency converter 2 needs to be installed and fixed, the corresponding wedge-shaped pressing block 12 is arranged on the flat plate pressing block 11 at one end, so that the first inclined surface 121 of the wedge-shaped pressing block 12 faces the middle direction. Then, the two ends of the heat-conducting plate 21 assembled on the frequency converter 2 are close to the two flat plate pressing blocks 11 respectively, so that one end of the heat-conducting plate 21 is embedded in the pressing block assembly 1 in which the wedge-shaped pressing block 12 has been assembled, and the edge of the heat-conducting plate 21 is close to the first inclined surface 121 of the wedge-shaped pressing block 12. The wedge-shaped pressing block 12 is assembled on the flat plate pressing block 11 at the other end, so that the first inclined surface 121 of the wedge-shaped pressing block 12 is close to the edge of the heat-conducting plate 21. During the assembly of the wedge-shaped pressing block 12, the first inclined surface 121 of the wedge-shaped pressing block 12 on the pressing block assembly at the two ends generates a component force in the vertical direction of the first inclined surface 121, which presses the heat-conducting plate 21 on the radiator 3, and generates a force in the direction of the inside of the heat-conducting plate 21, so that the pressing block assembly 1 at the two ends forms a tight clamping force on the heat-conducting plate 21, thereby tightly pressing the heat-conducting plate 21 on the radiator 3. The pressing effect can not only ensure the good heat conduction efficiency between the frequency converter 2 and the radiator 3, so that the frequency converter 2 can be cooled in time and the normal working temperature is maintained, but also can effectively prevent the frequency converter 2 from loosening due to vibration in a high-vibration environment, thereby ensuring the stability and reliability of the whole system.

[0048] In the installation process, the side of the wedge-shaped pressing block 12 of the pressing block assembly 1 becomes a stable and reliable support point. When the operator places the frequency converter 2 into the installation position and preliminarily aligns the hole position, it is not necessary to manually support the heavy frequency converter 2 for screw locking throughout the whole process. Only one end of the heat conduction plate 21 of the frequency converter 2 needs to be leaned against the pressing block assembly 1 of the wedge-shaped pressing block 12 that is not removed, and the assembly and fixation of the wedge-shaped pressing block 12 on the other side can be easily carried out. Similarly, in the process of disassembling the frequency converter 2, the pressing block assembly 1 of the wedge-shaped pressing block 12 that is not removed can also provide effective support for the frequency converter 2 and the heat conduction plate 21, avoiding the situation that the frequency converter 2 suddenly falls or shifts due to the loss of fixation, thereby ensuring the safety and stability in the disassembly process. This way of providing support by the single-side pressing block assembly 1 in the assembly and disassembly process greatly simplifies the installation efficiency, effectively reduces the overall labor intensity and operation difficulty, and brings great convenience to the maintenance work of the mine-used frequency converter 2.

[0049] In some optional embodiments, steel or aluminum material is used as the manufacturing material of the wedge-shaped pressing block and the flat pressing block 11, so as to ensure that the pressing block assembly 1 has good structural strength and meets the special needs of mine-used equipment.

[0050] In some embodiments, the wedge-shaped pressing block 12 and the flat pressing block 11 are connected and fixed by a first fastener, and the flat pressing block 11 and the heat sink 3 are connected and fixed by a second fastener. According to different design requirements, the first fastener and the second fastener can adopt one or more of screws, pins or buckles to meet the connection and fixation requirements between the wedge-shaped pressing block 12 and the flat pressing block 11 and between the flat pressing block 11 and the heat sink 3. Specifically, but not limited to, the following assembly methods:

[0051] In some optional embodiments, a plurality of through holes 122 are uniformly arranged on the wedge-shaped pressing block 12, a via hole 112 corresponding to the through hole 122 is arranged on the flat pressing block 11, and a first threaded hole 31 corresponding to the through hole 122 and the via hole 112 is arranged on the heat sink 3. A screw is sequentially threaded through the through hole 122 and the via hole 112 and locked in the first threaded hole 31 to lock and fix the pressing block assembly 1 and the heat sink 3. The wedge-shaped pressing block 12 is locked on the flat pressing block 11 and the heat sink 3 by the screw to ensure the stability of the structure of the whole pressing block assembly 1, so that the pressing block assembly 1 can withstand the vibration and impact in the mine environment.

[0052] In some optional embodiments, the wedge-shaped pressing block 12 is uniformly provided with a plurality of through holes 122, the flat plate pressing block 11 is provided with a through hole 112 corresponding to the through hole 122, the heat dissipation device 3 is provided with a pin hole corresponding to the through hole 122 and the through hole 112, a pin is punched into the pin hole, and one end of the pin is extended out of the pin hole, so that when the flat plate pressing block 11 and the wedge-shaped pressing block 12 are assembled, the pin is inserted into the through hole 112 and the through hole 122, so as to realize the fixing and limiting of the flat plate pressing block 11 and the wedge-shaped pressing block 12.

[0053] In some optional embodiments, the flat plate pressing block 11 is provided with a buckle, and the wedge-shaped pressing block 12 is provided with a buckle position corresponding to the buckle. When the wedge-shaped pressing block 12 is assembled, the buckle on the flat plate pressing block 11 is embedded into the buckle position of the wedge-shaped pressing block 12, so as to realize the locking and fixing between the wedge-shaped pressing block 12 and the flat plate pressing block 11.

[0054] In some optional embodiments, please refer to Figure 6 , the flat plate pressing block 11 is provided with a plurality of counterbores 113, and the heat dissipation device 3 is provided with a second threaded hole 32 corresponding to the counterbores 113. The flat plate pressing block 11 is fixed and locked with the heat dissipation device 3 by screwing a screw through the counterbores 113 and locking it in the second threaded hole 32. When the screw is locked in the second threaded hole 32, the head of the screw is located in the counterbores 113 and is flush with or lower than the surface of the flat plate pressing block 11. By accommodating the head of the screw in the counterbores 113, the head of the screw can be completely hidden in the counterbores 113 when the flat plate pressing block 11 is locked on the heat dissipation device 3 by the screw, avoiding interference with the screw on the flat plate pressing block 11 when the wedge-shaped pressing block 12 is installed, ensuring that the overall pressing block assembly 1 is flat, beautiful and stable, and improving the compactness of the overall structure.

[0055] In some embodiments, please refer to Figure 5 , Figure 6 , the flat plate pressing block 11 is provided with a second inclined surface 111 facing the direction of the heat conduction plate 21. By providing the second inclined surface 111 on the flat plate pressing block 11 facing the direction of the heat conduction plate 21, the heat conduction plate 21 can be guided to the center direction by the second inclined surface 111 when the heat conduction plate 21 is installed and fixed, so as to be pressed and fixed by the wedge-shaped pressing block 12 of the pressing block assembly 1 at both ends. At the same time, during the disassembly of the frequency converter 2, the space gap between the heat conduction plate 21 and the flat plate pressing block 11 can be increased, so that the frequency converter 2 is more easily taken out between the pressing block assemblies 1 at both ends.

[0056] Secondly, please refer to Figure 7The application further provides an industrial control device assembly, comprising: a heat-conducting plate 21 and an industrial control device mounted on the heat-conducting plate 21, wherein the heat-conducting plate 21 is fixedly arranged on the heat sink 3 through the block assembly 1 with the detachable structure as described above. The industrial control device is mounted and fixed on the heat-conducting plate 21, and the heat-conducting plate 21 plays a crucial role as a key transition component connecting the industrial control device and the heat sink 3. In the embodiments provided by the application, the frequency converter 2 is taken as the industrial control device, and the frequency converter 2 is arranged on the heat-conducting plate 21.

[0057] The heat-conducting plate 21 is mainly used for transferring the heat generated by the industrial control device during operation to the heat sink 3, and then dissipating the heat to the outside through the heat sink 3, so as to avoid the accumulation of a large amount of heat in the industrial control device, which causes the circuit components inside the industrial control device to be in a high-temperature state for a long time, and then causes the electrical performance of the circuit components to be affected by the heat, and even causes the service life of the circuit components to be shortened due to the heat, resulting in an increase in maintenance cost. In order to improve the heat conduction efficiency and provide corresponding assembly support for the industrial control device, an aluminum plate or a copper plate is generally used as the heat-conducting plate 21, so as to effectively control the production cost while meeting the heat conduction and ensuring the rigidity of the heat-conducting plate 21.

[0058] In some embodiments, referring to Figure 5 , In some embodiments, referring to Figure 7 , opposite ends of the heat-conducting plate 21 are provided with third inclined surfaces 211 corresponding to the first inclined surfaces 121 of the wedge-shaped blocks 12, and the first inclined surfaces 121 and the third inclined surfaces 211 are in movable contact. By providing the third inclined surfaces 211 on the heat-conducting plate 21 corresponding to the wedge-shaped blocks, and tightly and accurately fitting between the first inclined surfaces 121 and the third inclined surfaces 211, this arrangement not only increases the contact area between the wedge-shaped blocks 12 and the heat-conducting plate 21, but also improves the stability and reliability of the overall assembly, and can automatically correct the relative position of the heat-conducting plate 21 and the blocks during installation, reduce installation errors, and ensure installation accuracy.

[0059] In some embodiments, referring to Figure 8 , one end or both ends of the heat-conducting plate 21 corresponding to the block assembly 1 are provided with protrusions 212, the block assembly 1 corresponding to the protrusions 212 of the heat-conducting plate 21 is provided with grooves 13, and the protrusions 212 are clamped in the grooves 13. By accurately clamping the protrusions 212 into the grooves 13 of the block assembly 1, a stable clamping connection structure is formed, which can effectively prevent the frequency converter 2 from shifting or shaking during operation, and further enhances the stability of the overall structure. Through the cooperation of the grooves 13 and the protrusions 212, the translation of the heat-conducting plate 21 is limited by the grooves 13, effectively ensuring the accurate position of the frequency converter 2 after installation.

[0060] In some embodiments, the block assembly 1 is arranged at the upper and lower ends and / or the left and right ends of the heat conduction plate 21. According to the spatial layout of the equipment, the block assembly 1 can be arranged at the upper and lower ends or the left and right ends of the heat conduction plate 21 for different equipment to meet the assembly and fixing requirements between the heat conduction plate 21 and the heat sink 3 under different layout conditions.

[0061] In some optional embodiments, referring to Figure 3 , Figure 7 , the block assembly 1 is arranged at the upper and lower ends, and during the assembly and fixing of the frequency converter 2, the wedge-shaped block 12 of the lower block assembly 1 is prearranged on the flat block 11, so that the lower block assembly 1 provides support and limiting for the frequency converter 2 during the assembly process, and thus manual support of the heavy frequency converter 2 is not required for screw locking operation. During the disassembly process of the frequency converter 2, the lower block assembly 1 can also provide effective support for the frequency converter 2 and the heat conduction plate 21, avoiding the sudden falling or displacement of the frequency converter 2 due to loss of fixation, thereby ensuring the safety and stability during the disassembly process.

[0062] In some optional embodiments, referring to Figure 9 , Figure 10 , the block assembly 1 is arranged at the left and right ends, and during the assembly and fixing of the frequency converter 2, the wedge-shaped block 12 of the right block assembly 1 is prearranged on the flat block 11, so that the right block assembly 1 provides support and limiting for the frequency converter 2 during the assembly process, and thus the right side of the heat conduction plate 21 is inserted into the right block assembly 1, so that the protrusion 212 on the right side of the heat conduction plate 21 is embedded in the groove 13 of the right block assembly 1, and the groove 13 provides limiting and fixing for the up and down movement of the right side of the heat conduction plate 21. During the assembly process, the right block assembly 1 and the left flat block 11 provide effective support and limiting for the frequency converter 2, so that manual support of the right side of the frequency converter 2 is not required during the installation and fixing of the left wedge-shaped block 12. During the disassembly process of the frequency converter 2, the groove 13 of the right block assembly 1 cooperates with the protrusion 212 on the right side of the heat conduction plate 21, and the groove 13 on the left flat block 11 cooperates with the protrusion 212 on the heat conduction plate 21, to provide effective support and limiting, avoiding the sudden falling or displacement of the frequency converter 2 due to loss of fixation, thereby ensuring the safety and stability during the disassembly process.

[0063] In some embodiments, referring to Figure 8 , Figure 11, the convex block 212 of the heat-conducting plate 21 is provided with a third threaded hole 213, a disassembly screw 4 is movably screwed into the third threaded hole 213, the length of the screw rod of the disassembly screw 4 is greater than the maximum thickness of the heat-conducting plate 21, the disassembly screw 4 is screwed into the third threaded hole 213 and the end of the screw rod of the disassembly screw 4 is in contact with the surface of the radiator 3. In operation, the disassembly screw 4 is screwed into the third threaded hole 213 on the heat-conducting plate 21, and the disassembly screw 4 is continuously screwed until the end of the screw rod is in contact with the surface of the radiator 3. Since the length of the disassembly screw 4 is greater than the thickness of the heat-conducting plate 21, the continuous screwing of the disassembly screw 4 will exert a force on the heat-conducting plate 21 away from the radiator 3 during the continuous screwing of the disassembly screw 4, so as to lift the heat-conducting plate 21. In this process, the disassembly screw 4 lifts one end of the heat-conducting plate 21, so that air can effectively enter between the heat-conducting plate 21 and the radiator 3, reducing the viscosity of the heat-conducting silicone grease coated between the heat-conducting plate 21 and the radiator 3, thereby facilitating the removal of the heat-conducting plate 21 from the radiator 3, effectively solving the problem of difficult disassembly of the heat-conducting plate 21 due to adsorption of the heat-conducting silicone grease.

[0064] In some embodiments, referring to Figure 11 , the heat-conducting plate 21 is provided with a space gap 214 on one or more edges of the outer side edge of the side of the heat-conducting plate 21 facing the radiator 3, so that the outer side edge of the heat-conducting plate 21 and the radiator 3 are kept apart by a distance of the width of the space gap 214 when the heat-conducting plate 21 is fixed to the radiator 3 by the pressing block assembly 1. When the disassembly screw 4 lifts the heat-conducting plate 21, the surface of the radiator 3 contacted by the disassembly screw 4 may have protruding burrs due to contact with the disassembly screw 4. By providing the space gap 214, such protruding burrs can be effectively avoided to cause the radiator 3 and the heat-conducting plate 21 to not fit tightly, thereby avoiding the problem of affecting the heat dissipation effect of the frequency converter 2, ensuring the stable and reliable heat dissipation performance of the frequency converter 2 during operation, and further ensuring the stable operation of the overall equipment.

[0065] In the embodiments provided in the present application, the heat-conducting plate 21 connected to the frequency converter 2 is pushed towards the radiator 3 and the center of the heat-conducting plate 21 by the first inclined surface 121 on the wedge-shaped pressing block 12, and a corresponding pushing force is applied to the heat-conducting plate 21 to achieve the effect of clamping and positioning the heat-conducting plate 21. At the same time, during assembly, the wedge-shaped pressing block at one end is first fixed on the flat plate pressing block 11 to provide support for the heat-conducting plate 21 of the frequency converter 2, thereby solving the problem of needing additional personnel to support the frequency converter 2 during disassembly and assembly of the frequency converter 2, meeting the operation requirements in a small space, effectively ensuring the overall disassembly and assembly efficiency, improving the convenience of frequency converter 2 assembly, maintenance and inspection, and improving the overall practicality and stability of the equipment, providing more reliable technical support for the use and maintenance of the mine frequency converter 2.

[0066] In the above-described embodiments, the description of each embodiment focuses on different aspects, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.
