Description

Technical Field

[0001] This invention relates to the field of equipment installation, and more particularly to a fixed guide rail. Background Technology

[0002] During the transportation and on-site application of various large-scale equipment, the modular units inside the equipment usually need to be arranged compactly in a limited space to ensure stability during long-term operation and transportation vibrations.

[0003] For example, a vehicle-mounted containerized nitrogen generator typically consists of a gas source module, a purification and drying module, a nitrogen generation module, a control module, a pressurization module, and a gas storage module, with each module rationally arranged inside the container. Because vehicle-mounted containerized nitrogen generators are subject to vibration and jolting during long-term transportation, securing each module requires consideration of both the bottom and sides. Furthermore, the limited installation and maintenance space inside the container can prevent personnel from entering once the equipment is in place. Traditional fixing methods often employ permanent connections such as bolts or welding, which makes disassembly and assembly difficult during equipment maintenance or component replacement, increasing operational intensity and limiting maintainability and space utilization efficiency.

[0004] There is currently no effective solution to the above problems in existing technologies. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a fixed guide rail. Through the slidable cooperation between the guide rail assembly and the rail groove assembly, the equipment module can be stably installed and pulled out for maintenance within a limited space, thus balancing transportation safety and convenient maintenance.

[0006] To achieve the above objectives, the present invention also provides a fixed guide rail, comprising: a guide rail assembly and a rail groove assembly; one side of the rail groove assembly is used to connect with the inner wall of the housing, and the other side cooperates with the guide rail assembly; one side of the guide rail assembly is used to connect with the module to be installed, and the other side can slide relative to the rail groove assembly in an unfixed state.

[0007] Optionally, the rail groove assembly includes a groove; one end of the groove is open, and a first wedge block is provided on the inner wall of the other end; one end of the guide rail assembly is provided with a second wedge block adapted to the first wedge block, and the end of the second wedge block enters from the open end of the groove. When it moves to the closed end of the groove, the second wedge block and the first wedge block are fitted together.

[0008] Optionally, the rail groove assembly includes a reinforcing base plate; the reinforcing base plate is located on the side where the groove connects to the box body and is used to connect with the inner wall of the box body.

[0009] Optionally, the guide rail assembly includes a guide rail body and a top plate; the top plate is disposed at one end of the guide rail body.

[0010] Optionally, the side of the guide rail body that contacts the rail groove assembly is provided with at least one sliding element.

[0011] Optionally, the sliding element includes: a roller, a retainer, and a connector; the retainer is fixed to the guide rail body via the connector; the roller's shaft is connected to the retainer.

[0012] Alternatively, the top plate may be provided with lifting rings.

[0013] Optionally, the end of the rail groove assembly is provided with a limiting block corresponding to the top plate. When the guide rail assembly and the rail groove assembly are installed in place, the top plate contacts the limiting block.

[0014] Optionally, the top plate has a first connecting hole, and the limiting block has a second connecting hole corresponding to the first connecting hole; when the guide rail assembly and the rail groove assembly are installed in place, the first connecting hole and the second connecting hole are in corresponding positions and are connected by locking screws.

[0015] Optionally, the rail groove assembly is connected to the inner wall of the housing by fastening bolts; the guide rail assembly is connected to the module to be installed by connecting bolts.

[0016] The above technical solution has the following beneficial effects: due to its low overall height and compact structure, it can be installed in the limited space of a container without affecting the module layout; furthermore, due to the multi-faceted interlocking structure of the wedge blocks inside the guide rail and the wedge clamping blocks in the guide rail, the module can still be firmly fixed during transportation vibration, thereby improving the operational safety of the equipment; at the same time, the length and number of the guide rail can be flexibly adjusted according to the size and weight of the module, achieving efficient module adaptation; in addition, through the sliding fit between the guide rail and the rail groove, the frictional resistance during module pulling is greatly reduced, significantly improving loading, unloading and maintenance efficiency.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To address the problems of unstable device module fixation, difficult maintenance, and low space utilization in existing technologies, this invention provides a fixed guide rail. Please refer to [reference needed]. Figures 1-6 , Figure 1 This is a schematic diagram of the fixed guide rail installed in place according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the fixed guide rail provided in this embodiment of the invention during use; Figure 3 This is a schematic diagram of the pull-out structure of the fixed guide rail assembly provided in an embodiment of the present invention; Figure 4 This is a schematic diagram of the track groove assembly provided in an embodiment of the present invention; Figure 5 This is a schematic diagram of the guide rail assembly provided in an embodiment of the present invention; Figure 6 This is a schematic diagram of the wedge-tightening block connection structure provided in an embodiment of the present invention; Figure 7 This is a schematic diagram of the sliding component provided in an embodiment of the present invention.

[0022] like Figure 1 , Figure 2 As shown, the fixed guide rail 100 includes: a guide rail assembly 1 and a rail groove assembly 2; one side of the rail groove assembly 2 is used to connect with the inner wall of the housing 300, and the other side cooperates with the guide rail assembly 1; one side of the guide rail assembly 1 is used to connect with the module 200 to be installed, and the other side can slide relative to the rail groove assembly 2 in the unfixed state.

[0023] The fixed guide rail consists of two main parts: the guide rail assembly 1 and the rail groove assembly 2. The rail groove assembly 2 is installed on the inner wall of the container and is the load-bearing foundation structure of the entire guide rail system. After connection, it can ensure that the structure remains stable under transportation vibration and impact loads. The other side of the rail groove assembly 2 is set as a mounting surface that mates with the guide rail assembly 1, and is used to guide, support, and restrict the movement direction of the guide rail assembly 1.

[0024] The guide rail assembly 1 is used to connect with the equipment module to be placed and is the main component for realizing the sliding and fixing of the module. One side of the guide rail assembly 1 is used to connect with the equipment module and can be fixed to the bottom or side wall of the module through mechanical connectors to achieve a reliable connection between the module and the guide rail; the other side is set opposite to the rail groove assembly 2 and can slide along the direction of the rail groove assembly 2 in the unfixed state, thereby realizing the smooth pushing in or pulling out of the equipment module.

[0025] With this sliding fit structure, the equipment module can smoothly slide into the container along the guide rail during installation, and then be fixed in place by a locking mechanism after reaching the designed position; for example Figure 3 As shown, during later maintenance, the module can be easily pulled out for inspection simply by loosening the locking structure, without the need for personnel to enter the narrow interior of the container, greatly improving operational convenience and safety.

[0026] The overall guide rail height is low (e.g., around 38mm), which can effectively save installation space inside the container and does not affect the layout of various functional modules and airflow channels.

[0027] The various modules of the equipment may have different sizes. The length of the fixed guide rail can be adjusted according to the size of each module to achieve length matching with different modules. In addition, the weight of each module is also different. The number of fixed guide rails can be flexibly increased or decreased according to the different weights of each module and the adjustment of the center of gravity, and the installation position of the fixed guide rails can be optimized to achieve adaptation with each module.

[0028] As an optional implementation method, such as Figure 3-6As shown, the rail groove assembly 2 includes a groove 201; one end of the groove 201 is open, and a first wedge block 202 is provided on the inner wall of the other end; one end of the guide rail assembly 1 is provided with a second wedge block 105 that is adapted to the first wedge block 202. The end of the second wedge block 105 enters from the open end of the groove 201. When it moves to the closed end of the groove 201, the second wedge block 105 cooperates with the first wedge block 202 for installation.

[0029] The main component of the rail groove assembly 2 is the groove body 201, which has a receiving groove for supporting the guide rail assembly 1. One end of the groove body 201 is open for inserting and removing the guide rail assembly 1, and the inner wall of the other end is provided with a first wedge block 202. A second wedge block 105 is correspondingly provided at one end of the guide rail assembly 1, and the shape of the second wedge block 105 matches that of the first wedge block 202.

[0030] like Figure 6 As shown, the two side wedge surfaces and the bottom wedge surface of the second wedge block 105 cooperate with the two side wedge surfaces and the bottom wedge surface of the first wedge block 202. When the fixing is completed, the second wedge block 105 inside the guide rail assembly 1 and the first wedge block 202 of the rail groove assembly 2 fully engage on the three contact surfaces, which can limit the relative movement between the rectangular guide rail assembly 1 and the guide rail groove assembly 2 to the greatest extent. This allows the various modules of the nitrogen generator to be tightly fixed in the container during vehicle transportation, reducing the possibility of shaking or even tipping over during transportation, thereby ensuring the transportation safety of the nitrogen generator.

[0031] As an optional implementation method, such as Figure 4 As shown, the rail groove assembly 2 includes a reinforcing base plate 204; the reinforcing base plate 204 is located on the side where the groove body 201 connects to the box body, and is used to connect with the inner wall of the box body.

[0032] The reinforced base plate 204 serves as the connecting and load-bearing structure between the rail groove assembly 2 and the housing, playing a dual role in structural reinforcement and force transmission within the entire guide rail system. Firstly, the reinforced base plate 204 is connected to the inner wall of the housing via fastening bolts 5, welding, or high-strength riveting, which evenly distributes the load generated by the guide rails and equipment modules during transportation and loading / unloading onto the housing structure, preventing housing deformation or rail groove loosening due to localized stress concentration. Secondly, the reinforced base plate 204 serves as the mounting base for the groove 201, providing a flat and highly rigid mounting surface to ensure that the groove 201 maintains a stable horizontal state after installation, thereby guaranteeing the smoothness and accuracy of pushing and sliding the guide rail assembly 1 in and out.

[0033] As an optional implementation method, such as Figure 3 As shown, the guide rail assembly 1 includes a guide rail body 101 and a top plate 102; the top plate 102 is located at one end of the guide rail body 101.

[0034] The guide rail body 101 is the core load-bearing component of the guide rail assembly 1. Its cross-section is typically rectangular or approximately rectangular, and it is mainly used to cooperate with the groove 201 of the rail groove assembly 2 to achieve guiding, sliding, and load-bearing functions. Its upper surface is used to connect with the equipment module to be installed, and is rigidly fixed by bolts, nuts, or connectors, thereby effectively transferring the weight and operating load of the equipment module to the rail groove assembly 2 and the housing structure; its lower surface is used to cooperate with the groove 201 of the rail groove assembly 2.

[0035] The top plate 102 is installed at the front end of the guide rail body 101, which can seal the end of the guide rail and prevent dust or foreign objects from entering the sliding area.

[0036] As an optional implementation method, such as Figure 3 As shown, at least one sliding member 103 is provided on the side of the guide rail body 101 that contacts the rail groove assembly 2.

[0037] The sliders 103 are disposed between the contact surfaces of the guide rail body 101 and the rail groove assembly 2, and are typically evenly distributed along the length of the guide rail. Preferably, in this embodiment, each guide rail body 101 includes three evenly distributed sliders 103.

[0038] The sliding element 103 can take the form of a roller, slider, or wheel, and is installed on the bottom or side of the guide rail body 101. It supports the weight of the guide rail assembly 1 and its mounted equipment modules, and provides support and guidance when the guide rail assembly 1 slides along the rail groove. The sliding element 103 ensures that the guide rail assembly 1 maintains smooth linear movement during pushing in or pulling out, effectively avoiding jamming, wear, or noise problems caused by direct metal contact. Furthermore, it allows the installed modules to be moved in and out with less external force, which not only reduces manual labor and improves loading and unloading efficiency, but also reduces wear on the guide rail and rail groove surfaces, extending the service life of the entire structure.

[0039] In addition, the sliding component 103 adopts a high-strength nylon, polytetrafluoroethylene, stainless steel roller or composite bearing structure to take into account load-bearing capacity, vibration resistance and wear resistance; some sliding components 103 can also be designed as replaceable modules to facilitate maintenance or replacement after long-term use, ensuring that the guide rail system maintains smooth sliding performance for a long time.

[0040] As an optional implementation method, such as Figure 7 As shown, the sliding member 103 includes: a roller 1032, a retainer 1031, and a connector 1033; the retainer 1031 is fixed to the guide rail body 101 through the connector 1033; the rotating shaft of the roller 1032 is connected to the retainer 1031.

[0041] The retainer 1031 serves for positioning and load-bearing, and is securely connected to the guide rail body 101 via bolts or pins or other connecting parts 1033, ensuring that the sliding component 103 does not loosen or shift under long-term operation and vibration conditions. The roller 1032 is mounted on the retainer via a rotating shaft, enabling continuous rolling as the guide rail assembly 1 slides along the rail groove, thereby significantly reducing the friction between the guide rail and the rail groove. The outer surface of the roller contacts the inner wall of the groove 201 of the rail groove assembly 2, forming a linear rolling support, which improves the smoothness of pushing and pulling the guide rail assembly 1 in and out, and avoids surface wear and metal shavings accumulation caused by sliding friction. Each retainer includes one or more rollers.

[0042] The sliding element 103 can evenly distribute pressure when the guide rail is under load, improving the overall load-bearing capacity and stability of the guide rail assembly 1. The roller material can be selected from stainless steel or wear-resistant engineering plastics according to the usage environment to balance impact resistance and wear resistance; the retainer is made of high-strength alloy or composite material to ensure reliability under vehicle vibration and frequent operation conditions.

[0043] As an optional implementation method, such as Figure 3 As shown, the top plate 102 is equipped with a lifting ring 104.

[0044] The lifting ring 104 is located in a prominent position on the top plate 102 of the guide rail assembly 1. It can be fixedly connected to the top plate 102 by means of threaded connection, welding, or integral casting, and has high mechanical strength and load-bearing capacity. When it is necessary to pull out or push in the equipment module along the guide rail, the operator can attach a traction rope, hook, or lifting device to the lifting ring 104 to achieve smooth movement of the module by using external force, thereby avoiding the safety risks and labor intensity caused by direct manual pushing.

[0045] The material of the 104 lifting ring is usually high-strength carbon steel or stainless steel, and it has undergone rust prevention, anti-loosening and strength verification treatment to ensure that it will not suffer fatigue fracture or deformation under long-term vibration and load.

[0046] As an optional implementation method, such as Figure 3 As shown, the end of the rail groove assembly 2 is provided with a limiting block 203 corresponding to the top plate 102. When the guide rail assembly 1 and the rail groove assembly 2 are installed in place, the top plate 102 contacts the limiting block 203.

[0047] The limiting block 203 is fixedly installed at the end of the rail groove assembly 2, that is, on both sides of the opening end of the groove 201, and its position corresponds to the front end of the top plate 102 of the guide rail assembly 1. When the guide rail assembly 1 is pushed in along the rail groove direction, the top plate 102 contacts the limiting block 203 after reaching the designed end point, forming a clear mechanical stop, so that the guide rail assembly 1 stops sliding further. Through this contact limiting method, the guide rail assembly 1 can be prevented from being pushed in too far, which would cause interference with other components in the box, and the accuracy and repeatability of the equipment module installation position can be ensured.

[0048] As an optional implementation method, such as Figure 3 As shown, the top plate 102 has a first connecting hole, and the limiting block 203 has a second connecting hole corresponding to the first connecting hole; when the guide rail assembly 1 and the rail groove assembly 2 are installed in place, the first connecting hole and the second connecting hole are in the same position and are connected by the locking screw 4.

[0049] After the guide rail assembly 1 slides into the predetermined position along the rail groove direction, the top plate 102 and the limiting block 203 first form a surface contact limit. At this time, the connecting holes on both are precisely aligned. The operator can insert and tighten the locking screw 4 to rigidly connect the top plate 102 and the limiting block 203 together, thereby eliminating the residual gap between the guide rail assembly 1 and the rail groove assembly 2. This locking structure can prevent the guide rail assembly 1 from generating slight axial displacement during vehicle transportation vibration or equipment operation, further enhancing the overall stability and impact resistance of the guide rail system.

[0050] As an optional implementation method, such as Figure 3 , Figure 4 As shown, the rail groove assembly 2 is connected to the inner wall of the box by fastening bolts 5; the guide rail assembly 1 is connected to the module to be installed by connecting bolts 3.

[0051] The rail groove assembly 2 serves as the fixed foundation for the entire guide rail system, with one side connected to the inner wall of the housing via fastening bolts 5. The fastening bolts 5 can pass through the reinforcing base plate 204 of the rail groove assembly 2 and be screwed into the inner wall of the housing or into pre-set threaded holes, forming a rigid connection. This connection method allows the rail groove assembly 2 to stably withstand the weight of the equipment module and the vibration and impact forces generated during transportation, ensuring that the guide rail system does not loosen or shift during long-term operation. Simultaneously, the structure of the fastening bolts 5 facilitates later maintenance and replacement; when the housing structure or guide rail assembly 1 requires repair, it can be easily completed by disassembling the bolts.

[0052] The guide rail assembly 1 is also fixed to the module to be installed using connecting bolts 3. The bottom or side wall of the module has mounting holes corresponding to the guide rail assembly 1. The connecting bolts 3 pass through the mounting surface of the guide rail assembly 1 and connect to the module, allowing the load of the module to be transferred through the guide rail assembly 1 to the rail groove assembly 2 and the housing structure, achieving stable support. This structure not only ensures the module's shock and impact resistance during transportation but also avoids the problems of thermal deformation and maintenance difficulties caused by traditional welding fixing methods.

[0053] The above-mentioned fixed guide rails are used as follows: When it is necessary to install the various modules of the equipment into the container, the modules are connected to the guide rail assembly with connecting bolts, and the rail groove assembly is connected to the inner wall of the container with fastening bolts. Push the guide rail assembly into the rail groove assembly so that the wedge blocks at the ends come into contact; Secure the top plate and the limit block with locking screws. At this point, the wedge block will fully engage, completing the installation.

[0054] When a module needs maintenance, first loosen the locking screw to release the limit switch, then pull out the module to be repaired for further operation.

[0055] The above technical solution has the following beneficial effects: due to its low overall height and compact structure, it can be installed in the limited space of a container without affecting the module layout; furthermore, due to the multi-faceted interlocking structure of the wedge blocks inside the guide rail and the wedge clamping blocks in the guide rail, the module can still be firmly fixed during transportation vibration, thereby improving the operational safety of the equipment; at the same time, the length and number of the guide rail can be flexibly adjusted according to the size and weight of the module, achieving efficient module adaptation; in addition, through the sliding fit between the guide rail and the rail groove, the frictional resistance during module pulling is greatly reduced, significantly improving loading, unloading and maintenance efficiency.

[0056] The above-described specific embodiments of the invention further illustrate the purpose, technical solution, and beneficial effects of the invention. It should be understood that the above content is only for specific embodiments of the invention and is not intended to limit the scope of protection of the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
