Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a mining refrigeration equipment and its assembly method. Background Technology

[0002] Mining refrigeration equipment is a type of refrigeration equipment used underground in mines. To meet the large refrigeration demands, mining refrigeration equipment is usually quite large. However, due to the characteristics of the underground mining environment, the transport size is limited. Therefore, mining refrigeration equipment generally cannot be transported as a whole. Instead, it needs to be disassembled into parts on the mine first, and then the parts are transported underground for assembly. This process is cumbersome and difficult, which affects the application of mining refrigeration equipment underground.

[0003] The above statements are for the purpose of providing background information in relation to this application only, and do not necessarily constitute prior art. Summary of the Invention

[0004] This application aims to provide a mining refrigeration equipment and its assembly method to facilitate the use of the mining refrigeration equipment.

[0005] To achieve the above objectives, the mining refrigeration equipment provided in this application includes multiple refrigeration modules, each of which includes a refrigerant circulation system. The refrigerant circulation system enables refrigerant circulation to regulate temperature, and the multiple refrigeration modules are detachably connected to each other.

[0006] In some embodiments, a first flange is provided on the opposite surfaces of two detachably connected refrigeration modules. The mining refrigeration equipment also includes a connecting assembly, which includes a connecting pipe and two second flanges. The two second flanges are disposed at both ends of the connecting pipe and are detachably connected to the first flanges on the opposite surfaces of two adjacent refrigeration modules, so that the refrigeration modules are detachably connected; and / or, multiple refrigeration modules are connected in series.

[0007] In some embodiments, the first flange and the second flange are provided with flange holes respectively, and the first connector passes through the flange holes on the first flange and the second flange to detachably connect the first flange and the second flange.

[0008] In some embodiments, the refrigeration module further includes a housing and a support. The support is disposed inside the housing and located below the refrigerant circulation system to support the refrigerant circulation system, so that the height of the refrigerant circulation system can be adjusted by adjusting the height of the support; and / or, the mining refrigeration equipment further includes multiple bases, which are supported below the multiple refrigeration modules in a one-to-one correspondence, and the height of the bases is adjustable to adjust the height of the refrigeration modules.

[0009] In some embodiments, the position of the support on the housing is adjustable; and / or, the position of the cooling module on the base is adjustable.

[0010] In some embodiments, the position of the support on the housing along the arrangement direction of the two detachably connected refrigeration modules is adjustable; and / or, the position of the refrigeration module on the base along the arrangement direction of the two detachably connected refrigeration modules and / or in a direction perpendicular to the arrangement direction of the two detachably connected refrigeration modules and the vertical direction is adjustable.

[0011] In some embodiments, the support and the housing are connected by a first elongated hole to make the position of the support on the housing adjustable; and / or, the refrigeration module and the base are connected by at least one of a second elongated hole and a bulging hole to make the position of the refrigeration module on the base adjustable, the bulging hole being for a second connector for connecting the refrigeration module and the base to pass through, and the diameter of the bulging hole being larger than the outer diameter of the second connector for passing through the bulging hole.

[0012] In some embodiments, a first elongated hole is provided on the support; and / or, a second elongated hole is provided on the refrigeration module; and / or, an enlarged hole is provided on the base.

[0013] In some embodiments, the base includes a seat and a height adjustment mechanism. The seat supports the cooling module, and the height adjustment mechanism is connected to the seat to support the seat and adjust the height of the seat so that the base height is adjustable; and / or, multiple bases are detachably connected to each other.

[0014] In some embodiments, the height adjustment mechanism includes a threaded element connected to the base and used for ground support to adjust the height of the base; and / or, a limiting block is provided on the base, and the limiting blocks on two detachably connected bases are detachably connected together.

[0015] In addition, the assembly method for the mining refrigeration equipment provided in this application includes: At the mine, refrigeration modules are assembled. Multiple refrigeration modules were transported underground in the mine. In the mine, multiple cooling modules are detachably connected.

[0016] In some embodiments, the assembly method further includes: Before transporting multiple refrigeration modules to the mine, they are first detachably connected on the mine surface to achieve pre-assembly of the multiple refrigeration modules.

[0017] By configuring the mining refrigeration equipment as multiple refrigeration modules that can independently perform refrigeration functions and are detachably connected to each other, the delivery method of the mining refrigeration equipment can be changed from a piecemeal delivery method to a modular delivery method. While meeting the cooling capacity requirements of the mine and the transportation characteristics and specifications of the cages and underground roadways, the transportation and assembly difficulty of the mining refrigeration equipment can be effectively reduced, the underground assembly process of the mining refrigeration equipment can be simplified, the underground installation efficiency of the mining refrigeration equipment can be improved, and the mining refrigeration equipment can be used conveniently in the mine.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0030] In the description of this application, the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0031] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0032] In the description of this application, "multiple" means at least two, that is, two, three or more.

[0033] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Mining tunnels are typically long and narrow, requiring equipment and personnel to be transported in cages, which limits transport dimensions. However, the cooling requirements underground are generally high, and if the mining refrigeration equipment is too small, it will be difficult to meet these requirements. Therefore, mining refrigeration equipment is generally large; for example, the main unit of a common mining refrigeration unit is usually over 15 meters long, far exceeding the size of the cage (which is typically 2.5 or 3 meters long), making it impossible to transport as a whole.

[0035] To address the above situation, the common technical approach is to disassemble the mining refrigeration equipment, transport the disassembled parts to the mine via a cage, and then reassemble them underground. However, this method is cumbersome, difficult, and has the following problems: (1) Loose parts transportation involves a large number of parts, and the narrow and long underground mine tunnels can easily cause blockages and lead to safety accidents. (2) The installation period required for on-site assembly in the mine is much longer than that for the whole machine to be sent down into the mine, which will affect the construction period of underground tunneling and coal mining, and affect production efficiency and production benefits; (3) It is difficult to equip the mine with a full range of professional manufacturers' production tools and related professional technical installation personnel for on-site assembly, which affects the reliability of the equipment; (4) The underground environment is harsh, and the installation of loose parts on site greatly affects the physical and mental health and personal safety of the installers; (5) The installation of loose parts involves hot work (such as welding, cutting, grinding, drilling or heat treatment), which, combined with the flammable and explosive environment in the mine, can easily lead to explosion accidents.

[0036] It is evident that the mining refrigeration equipment in the relevant technologies is difficult to meet the transportation characteristics and specifications of cages and underground mine roadways. Furthermore, the method of disassembling large mining refrigeration equipment into individual parts and transporting them underground for assembly (which can be called the component delivery method) has problems such as underground blockage, potential fire and explosion hazards, impact on equipment reliability, long installation period, high labor intensity for installation personnel, and impact on their health and safety. These have become pain points in the application of mining refrigeration equipment, affecting its use underground, and therefore urgently need to be addressed.

[0037] In view of the above situation, this application provides a mining refrigeration equipment.

[0038] Figures 1-9 An example of a mining refrigeration device is shown in this application.

[0039] See Figures 1-9In this application, the mining refrigeration equipment 1 includes multiple refrigeration modules 2, each of which includes a refrigerant circulation system 21. The refrigerant circulation system 21 enables refrigerant circulation to regulate temperature, and the multiple refrigeration modules 2 are detachably connected to each other. The refrigerant circulation system 21 includes a compressor (not shown), two heat exchangers 24 (one used as a condenser and the other as an evaporator), and a throttling element (not shown), enabling the refrigerant circulation system 21 to circulate refrigerant and regulate temperature, thereby enabling the refrigeration modules 2 to circulate refrigerant and regulate temperature. Specifically, in some embodiments, the heat exchanger 24 is a shell-and-tube heat exchanger.

[0040] Based on the above configuration, the mine refrigeration equipment 1 is divided into multiple refrigeration modules 2 that can independently realize refrigerant circulation, forming a modular split cooling capacity design. In this way, the size of each refrigeration module 2 can be smaller than that of the mine roadway and cage, meeting the transportation characteristics and specifications of the cage and underground roadway. This facilitates the overall transportation of each refrigeration module 2 after it is assembled on the mine surface to the underground. Furthermore, since the multiple refrigeration modules 2 are detachably connected, after the refrigeration modules 2 are transported to the underground, they only need to be connected to each other to assemble the required mine refrigeration equipment 1. This is simple and convenient, effectively reducing the difficulty of transportation and assembly, simplifying the on-site assembly process in the mine, and improving on-site installation efficiency.

[0041] The method of transporting all the aforementioned refrigeration modules 2 as a whole to the mine for assembly can be called the modular delivery method. Compared with the component delivery method in related technologies, this modular delivery method has the following advantages: (1) Each cooling module 2 can be assembled on the mine and then transported as a whole to the mine. The number of parts is greatly reduced during transportation, which can reduce the risk of roadway blockage and improve safety. (2) Each cooling module 2 can be assembled on the mine, without the need to assemble each cooling module 2 underground. Underground, only the cooling modules 2 need to be detachably connected. Therefore, the underground installation cycle can be greatly shortened. This can not only reduce the impact of the installation of the mine cooling equipment on underground tunneling and coal mining operations, thereby improving production efficiency and benefits, but also reduce the input of underground installation personnel, reduce the labor intensity of installation personnel, and reduce the adverse effects of the harsh underground environment on the physical and mental health of installation personnel. (3) Each refrigeration module 2 is assembled on the mine, which facilitates the allocation of professional production tools and installation personnel, and improves the reliability of equipment operation; (4) Each refrigeration module 2 can perform a complete refrigerant cycle to achieve the refrigeration function, and different refrigeration modules 2 can be flexibly combined to meet different cooling requirements. For example, the refrigeration modules 2 can be connected in series, so that theoretically, the number of refrigeration modules 2 can be changed to achieve an unlimited cooling capacity assembly combination, effectively preventing the problem of cooling capacity mismatch when the equipment is put into use. Therefore, it can better meet the actual cooling capacity requirements of the mine.

[0042] It is evident that by modularly disassembling the cooling capacity design of the mining refrigeration equipment 1, and setting the mining refrigeration equipment 1 as including multiple independently refrigeration modules 2 that can independently realize cooling functions and are detachably connected to each other, the mining refrigeration equipment 1 is transformed from the loose parts entry method in related technologies to a modular entry method. This not only meets the transportation characteristics and specifications of cages and underground roadways, but also solves the core pain points such as underground blockage caused by loose parts on-site storage, affecting equipment reliability, long installation period, high labor intensity and health and safety of installation personnel. At the same time, it can also meet the cooling capacity requirements of the overall roadway, tunneling and coal mining. Therefore, it can effectively reduce the transportation and assembly difficulty of the mining refrigeration equipment 1, simplify the underground assembly process of the mining refrigeration equipment 1, improve the underground installation efficiency of the mining refrigeration equipment 1, and facilitate the use of the mining refrigeration equipment 1 underground.

[0043] Moreover, adopting a modular approach to site preparation helps reduce the risk of hot work explosions underground. Specifically, with a modular approach, the assembly of each cooling module 2 is completed above ground. Underground, only the cooling module 2 needs to be detachably connected. In this case, all hot work operations can be completed above ground, eliminating the need for hot work operations underground. This prevents underground gas explosions caused by hot work operations, reduces the risk of explosion, and improves construction safety.

[0044] To enable the assembly of the mining refrigeration equipment 1 underground without the need for hot work, the refrigeration modules 2 can be connected in a detachable manner without hot work. For example, see... Figure 1 and Figure 2 In some embodiments, a first flange 25 is provided on the opposing surfaces of the two detachably connected refrigeration modules 2. The mining refrigeration equipment 1 also includes a connecting assembly 4, which includes a connecting pipe 41 and two second flanges 42. The two second flanges 42 are disposed at both axial ends of the connecting pipe 41 and are detachably connected to the first flanges 25 on the opposing surfaces of two adjacent refrigeration modules 2, so that the refrigeration modules 2 are detachably connected. Specifically, see Figure 1 and Figure 2 In some embodiments, the first flange 25 and the second flange 42 are provided with flange holes 26 respectively, and the first connector 27 passes through the flange holes 26 on the first flange 25 and the second flange 42 to detachably connect the first flange 25 and the second flange 42.

[0045] Based on the above setup, the cooling modules 2 can be connected by connecting components 4. During the connection process, only the flanges need to be detached. Specifically, the first connector 27 is simply passed through the flange hole 26 on the flange. This not only makes it easy to detach the cooling modules 2, but also eliminates the need for welding or other operations and open flames during the detachable connection process, thus preventing explosions caused by open flames during installation and effectively improving construction safety.

[0046] Furthermore, by using the connecting assembly 4, which includes the connecting pipe 41, to connect different refrigeration modules 2, it is convenient to realize the series connection between the refrigeration modules 2, so as to flexibly meet different cooling capacity requirements by flexibly changing the number of refrigeration modules 2. For example, see Figure 4 and Figure 1 In some embodiments, the first flange 25 is disposed on the heat exchanger 24 of the refrigeration module 2, and the connecting pipe 41 is detachably connected to the heat exchanger 24 and communicates with the heat exchanger 24 through the cooperation of the second flange 42 and the first flange 25. This facilitates the series connection of the refrigeration modules 2, allowing for flexible adjustment of the number of refrigeration modules 2 to meet different cooling capacity requirements. In this case, each refrigeration module 2 can either circulate refrigerant independently or be connected in series with other refrigeration modules 2 for a wider range of refrigerant circulation. When the refrigeration modules 2 are connected in series, the cooling capacity is proportional to the number of refrigeration modules 2, and different cooling capacity requirements can be flexibly met by increasing or decreasing the number of refrigeration modules 2.

[0047] The assembly of the connecting component 4 can be completed on-site, allowing it to be transported underground as a whole without further assembly underground. This reduces transportation and assembly difficulties and simplifies the assembly process. Furthermore, assembling the connecting component 4 on-site also reduces the need for hot work operations underground, improving safety during the assembly process. For example, in some embodiments, the connecting component 4 is assembled by welding, i.e., the second flange 42 is welded to the connecting pipe 41. In this case, assembling the connecting component 4 on-site allows the welding between the second flange 42 and the connecting pipe 41 to be completed on-site, eliminating the need for further welding underground. This effectively reduces the risk of explosion underground and improves the safety of the assembly process. Moreover, welding the second flange 42 to the connecting pipe 41 increases pipe strength, effectively meeting the high-pressure connection requirements between the refrigeration modules. This method of welding the second flange 42 to the connecting pipe 41 is particularly suitable when the connecting pipe 41 is a rigid pipe. A rigid connecting pipe 41 better accommodates the high-pressure connection requirements between the refrigeration modules 2.

[0048] When a detachable connection is achieved between the first flange 25 and the second flange 42 through the cooperation of the flange holes 26 and the first connecting piece 27, multiple flange holes 26 can be provided on both the first flange 25 and the second flange 42. These flange holes 26 are arranged at intervals along the circumference of the flanges to further improve connection reliability. To further facilitate efficient assembly underground, the mining refrigeration equipment 1 can be pre-assembled on-site. During pre-assembly, each pair of flanges and each pair of flange holes 26 is uniquely numbered to facilitate rapid reassembly after disassembly. This allows for simple reassembly and connection underground, simply by following the markings. For example, the refrigeration module 2 can be placed according to the markings, aligned with the flange holes 26, and the first connecting piece 27 installed, thereby further improving underground assembly efficiency. The first connecting piece 27 can be various connectors such as bolts. When installing the first connecting piece 27, a gradient cross-symmetrical pre-tightening can be performed, followed by a fixed torque tightening. For example, torque can be applied in gradients of 35%, 60%, 80%, and 100% for pre-tightening and final tightening to improve connection strength.

[0049] See Figure 4 In some embodiments, the refrigeration module 2 includes not only the refrigerant circulation system 21, but also a housing 22 and a support 23. The support 23 is disposed inside the housing 22 and located below the refrigerant circulation system 21, providing support for the refrigerant circulation system 21. Specifically, the support 23 is disposed on the bottom plate 221 of the housing 22 and located below the heat exchanger 24 of the refrigerant circulation system 21, providing support for the heat exchanger 24. Based on this, the height difference between the refrigerant circulation system 21 and the base plate 221 of the shell 22 can be adjusted by adjusting the height of the support 23, thereby adjusting the height position of the refrigerant circulation system 21. In this way, the height position of the refrigerant circulation system 21 can be flexibly adjusted, which facilitates the alignment of the connection parts between different refrigeration modules 2 in the height direction for assembly. In particular, it is convenient to adjust the height position of the heat exchanger 24 so that the pipe connection ports (corresponding to the first flange 25 mentioned above) on the heat exchanger 24 between different refrigeration modules 2 are aligned in the vertical direction, improving coaxiality, so that the pipes between different refrigeration modules 2 can be connected, further reducing the assembly difficulty and improving the assembly efficiency.

[0050] The support 23 can be constructed as a saddle-type support, with its surface in contact with the refrigerant circulation system 21 being arc-shaped to better contact the arc-shaped surfaces of the heat exchanger 24, thereby improving support stability. The height of the support 23 can be adjusted by machining it flat to reduce its height, or by using shims or other shims to raise it. This height adjustment process can be carried out during pre-assembly in the mine, allowing for vertical alignment of the connection points between the refrigeration modules 2 during pre-assembly, reducing the difficulty of pre-assembly in the mine and improving the efficiency of both processes.

[0051] Furthermore, in some embodiments, the support 23 is not only height-adjustable but also position-adjustable on the housing 22. For example, in some embodiments, the position of the support 23 on the housing 22 is adjustable along the arrangement direction of the two detachably connected refrigeration modules 2 (referred to as the front-back direction), and / or, the position of the support 23 on the housing 22 is adjustable along a direction perpendicular to the arrangement direction and the vertical direction of the two detachably connected refrigeration modules 2 (referred to as the left-right direction). Thus, by changing the position of the support 23 on the housing 22, the position of the refrigerant circulation system 21 relative to the housing 22 can be changed. This not only facilitates the assembly of each refrigeration module 2 but also improves the positional consistency of the refrigerant circulation system 21 in different refrigeration modules 2, facilitates the alignment of connection points between different refrigeration modules 2, reduces positional adjustments during underground assembly (e.g., the adjustment of the position between the refrigeration module 2 and the base 3 mentioned below), reduces assembly difficulty, and improves assembly efficiency.

[0052] The position of the support 23 on the housing 22 can be adjusted in several ways. See one example. Figure 5 and Figure 6 The support 23 and the housing 22 are connected by a first elongated hole 28 (e.g., an oblong hole), allowing the position of the support 23 on the housing 22 to be adjustable. This allows for convenient adjustment of the support 23's position on the housing 22 based on a relatively simple structure. For example, see [link to previous section]. Figure 5 and Figure 6 In some embodiments, the support 23 and the housing 22 are connected by a first elongated hole 28, and the long axis of the first elongated hole 28 is along the arrangement direction (i.e., the front-to-back direction) of the two detachably connected cooling modules 2. This allows the front-to-back position of the support 23 on the housing 22 to be easily adjusted, reducing assembly difficulty and improving assembly efficiency. The first elongated hole 28 can be located on the support 23, making it easier to observe and adjust.

[0053] In each refrigeration module 2, the number of supports 23 is unlimited, and there can be one or more. When there are multiple supports 23, it is beneficial to achieve more stable support and to more accurately adjust the alignment of the connection parts between the two refrigeration modules 2.

[0054] In addition, other measures can be taken to adjust the alignment of the connection points between the two refrigeration modules 2.

[0055] For example, see Figures 1-3 as well as Figures 7-9In some embodiments, the mining refrigeration equipment 1 includes not only multiple refrigeration modules 2, but also multiple bases 3. The bases 3 are positioned one-to-one with each of the refrigeration modules 2, supporting them from below. The height of the bases 3 is adjustable to change the height of the refrigeration modules 2. This allows for easier alignment of the connecting parts between the refrigeration modules 2, facilitating assembly, reducing assembly difficulty, and improving assembly efficiency. In particular, the adjustable bases 3 are well-suited to uneven underground surfaces, ensuring that even on uneven surfaces, the connecting parts between the refrigeration modules 2 can be aligned vertically, further reducing assembly difficulty and improving assembly efficiency.

[0056] To make the height of base 3 adjustable, see [link / reference] Figure 7 and Figure 8 In some embodiments, the base 3 includes a seat 31 and a height adjustment mechanism 32. The seat 31 supports the cooling module 2, and the height adjustment mechanism 32 is connected to the seat 31 to support the seat 31 and adjust the height of the seat 31 so that the height of the base 3 is adjustable. In this way, the height of the seat 31 can be adjusted simply by adjusting the height adjustment mechanism 32, thereby changing the height position of the cooling module 2 on the seat 31, which is simple and convenient.

[0057] The number of height adjustment mechanisms 32 in the base 3 is unlimited; there can be one or more. When the base 3 includes multiple height adjustment mechanisms 32, it is beneficial to perform more precise vertical leveling.

[0058] Furthermore, the height adjustment mechanism 32 can take various structural forms. As one example, see... Figure 7 and Figure 8 The height adjustment mechanism 32 includes a threaded member 34, which is connected to the base 31 and serves to support the ground, thereby adjusting the height of the base 31. Specifically, see... Figure 7 and Figure 9 In some embodiments, the height adjustment mechanism 32 is an adjustable foot, and the threaded part 34 is an anchor bolt. It is supported by a pad 33 and passes through the mounting hole 38 on the base 31, and is locked by a nut 35 to connect with the base 31. In this way, by fixing the threaded part 34 at different height positions with the base 31, the height position of the base 31 and the refrigeration module 2 on the base 31 can be easily adjusted, realizing the vertical alignment adjustment between the refrigeration modules 2. This facilitates the interconnection between the refrigeration modules 2, and especially facilitates the pipe connection between the refrigeration modules 2 based on the rigid connecting pipe 41, thereby effectively reducing the assembly difficulty and improving the assembly efficiency.

[0059] Furthermore, to more effectively reduce assembly difficulty and improve assembly efficiency, see [link to documentation]. Figure 3 as well as Figures 5-8In some embodiments, the position of the cooling module 2 on the base 3 is adjustable. For example, in some embodiments, the position of the cooling module 2 on the base 3 is adjustable along the arrangement direction (i.e., the front-to-back direction) of the two detachably connected cooling modules 2, and / or the position of the cooling module 2 on the base 3 is adjustable along the direction perpendicular to the arrangement direction and the vertical direction (i.e., the left-to-right direction). Thus, by changing the front-to-back and / or left-to-right position of the cooling module 2 on the base 3, the front-to-back and / or left-to-right position of the connection part of the cooling module 2 used to connect with another cooling module 2 (e.g., the first flange 25 mentioned above) can be changed, further facilitating the alignment and connection of the connection parts between different cooling modules 2, reducing assembly difficulty, and improving assembly efficiency.

[0060] Various structural forms can be adopted to make the position of the cooling module 2 on the base 3 adjustable. For example, see [link to example]. Figure 3 as well as Figures 5-8 The cooling module 2 and the base 3 are connected by at least one of a second elongated hole 29 (e.g., an oblong hole) and an enlarged hole 37, allowing the position of the cooling module 2 on the base 3 to be adjustable. The enlarged hole 37 is used for a second connector 39 to pass through, and the diameter of the enlarged hole 37 is larger than the outer diameter of the second connector 39 through which it passes. This allows for convenient adjustment of the position of the cooling module 2 on the base 3 based on a relatively simple structure.

[0061] For example, see continue. Figure 3 as well as Figures 5-8 In some embodiments, the cooling module 2 and the base 3 are connected via a second elongated hole 29, and the long axis of the second elongated hole 29 is along the arrangement direction (i.e., the front-to-back direction) of the two detachably connected cooling modules 2. Specifically, the second elongated hole 29 is provided on the cooling module 2. More specifically, the second elongated hole 29 is provided on the housing 22 of the cooling module 2. In this way, the front-to-back position of the cooling module 2 on the base 3 can be easily adjusted, thereby facilitating the connection points between the two cooling modules 2 to be connected to move closer or further apart by changing the front-to-back position of the cooling module 2 on the base 3. This makes it easier for the fixed-length connecting assembly 4 to connect the two cooling modules 2 together, reducing assembly difficulty and improving assembly efficiency.

[0062] For example, see Figure 3 as well as Figures 5-8In some embodiments, the cooling module 2 and the base 3 are connected by an enlarged hole 37, and the diameter of the enlarged hole 37 is larger than the outer diameter of the second connector 39 used to connect the cooling module 2 and the base 3. Specifically, the enlarged hole 37 is provided on the base 3. More specifically, the enlarged hole 37 is provided on the base body 31 of the base 3. This allows the left and right positions of the cooling module 2 on the base 3 to be easily adjusted, thereby facilitating the left and right alignment of the connection parts between the two cooling modules 2 to be connected by changing the left and right positions of the cooling module 2 on the base 3, reducing assembly difficulty and improving assembly efficiency. The diameter of the enlarged hole 37 can be only slightly larger than the outer diameter of the second connector 39, because the adjustment requirements in the left and right directions are generally not large, and usually only a small adjustment in the left and right directions is sufficient. The second connector 39 may include bolts 5, etc. When the second connector 39 includes bolts 5, the bolts 5 can be locked with nuts to achieve a reliable connection.

[0063] The enlarged hole 37 provided on the base 3 can be used in combination with the second elongated hole 29 provided on the cooling module 2, so that the front-to-back position and left-to-right position of the cooling module 2 on the base 3 can be adjusted, so as to further facilitate the alignment and connection of the connection parts between the cooling modules 2, reduce the assembly difficulty, and improve the assembly efficiency.

[0064] It is understandable that the adjustment of the left and right position of the support 23 on the housing 22 mentioned above can also be achieved by enlarging the hole 37. For example, the enlarging hole 37 can be provided on the bottom plate 221 of the housing 22 so that the support 23 can be adjusted in the left and right position on the housing 22.

[0065] By adjusting the position of the refrigerant circulation system 21, the different refrigeration modules 2 can be aligned, which can reduce the need for positional adjustments to the connecting components 4. This is especially suitable for situations where the connecting pipe 41 is a rigid pipe and it is difficult to bend and connect misaligned refrigeration modules 2.

[0066] The bases 3 corresponding to different cooling modules 2 can be independent of each other or connected together. When multiple bases 3 are connected together, it is more conducive to improving structural reliability and enhancing support stability.

[0067] When multiple bases 3 are connected together, they can be detachably connected. This provides stable and reliable support after assembly, while allowing them to be separated during transportation, meeting the size restrictions of cages and roadways, and facilitating underground transport. See also Figure 3In some embodiments, the base 3 is provided with a limiting block 36, and the limiting blocks 36 on the two detachably connected bases 3 are connected together. In this way, the requirement for detachable connection between the two bases 3 is met, and the two bases 3 are reliably limited, which facilitates rapid assembly in the mine and also helps to improve the reliability and stability of the assembled structure. The limiting blocks 36 can be connected by bolts 5 or other simple and convenient methods.

[0068] Multiple bases 3 can be pre-assembled on the mine, then separated and transported independently to the underground mine for on-site assembly. During both pre-assembly and on-site assembly, the bases 3 can be leveled and connected together before each cooling module 2 is sequentially installed onto its corresponding base 3. During installation, the front-to-back and left-to-right positions of each cooling module 2 on its corresponding base 3 are adjusted to ensure proper alignment and connection between the modules.

[0069] Back Figure 1 In the embodiments of this application, multiple cooling modules 2 can be arranged in a straight line. In this way, the entire mining cooling equipment 1 is slender, which is more suitable for the narrow and slender characteristics of underground mine roadways, and also facilitates the connection of pipelines between the cooling modules 2.

[0070] Based on the mining refrigeration equipment 1 of various embodiments, this application also provides an assembly method for the mining refrigeration equipment 1, which includes: At the mine, refrigeration module 2 was assembled; Multiple refrigeration modules 2 were transported to the mine. In the mine, multiple cooling modules 2 are detachably connected.

[0071] The above assembly method, which adopts a modular approach to site entry, can effectively reduce the transportation and assembly difficulty of the mining refrigeration equipment 1, simplify the on-site assembly process of the mining refrigeration equipment 1 in the mine, improve the on-site installation efficiency of the mining refrigeration equipment 1, and make the mining refrigeration equipment 1 more convenient to use.

[0072] Furthermore, in some embodiments, the assembly method further includes: Before transporting multiple cooling modules 2 to the mine, they are first detachably connected on the mine surface to achieve pre-assembly of the multiple cooling modules 2.

[0073] By pre-assembling the equipment before it is transported to the mine, it is easier to assemble it quickly underground, which helps to further reduce the difficulty of underground assembly and improve the efficiency of underground assembly.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application 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 application or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this application.
