Description

TECHNICAL FIELD

[0001] The utility model relates to oxygen cabin technical field, concretely relates to support device and assembly tool for crossbeam assembly. BACKGROUND

[0002] In the modern health care field, the importance of oxygen cabin is increasingly prominent. The inside of oxygen cabin is carefully created 0.3-0.5kg / cm² atmospheric environment, and the construction of this special environment has extremely critical significance. When people are in the oxygen cabin, the increase of pressure causes the significant change of oxygen dissolving process. Under the conventional atmospheric environment, due to the limitation of pressure, the blood oxygen dissolving amount is relatively limited, and it is difficult to fully meet the high demand of human body for oxygen in some special conditions. But in the oxygen cabin, with the gradual rise of pressure, the situation has fundamentally changed. A large amount of oxygen as if found a breakthrough, continuously dissolves in the blood, so that the blood oxygen dissolving amount of human body presents extremely obvious growth trend. At the same time, the blood oxygen partial pressure is effectively improved, and the blood oxygen diffusion capacity is greatly enhanced. This means that the effective diffusion radius of oxygen is further increased, which can more deeply and widely reach each part of the body. In this way, when people carry out oxygen inhalation treatment and health care in the cabin, the hypoxic body can obtain effective and sufficient oxygen, thereby greatly increasing the oxygen content and oxygen storage in the tissue, providing a solid guarantee for the normal operation of each organ and tissue of the body, and finally playing a good health care treatment effect, helping people to relieve fatigue, enhance immunity and improve body function, etc.

[0003] The traditional house-shaped micro-pressure oxygen cabin is ingeniously designed, and special requirements for entering the family use are fully considered. In order to facilitate installation and later maintenance in the family environment, the overall structure is designed as an assembled structure convenient for installation and disassembly. In terms of material selection and process manufacturing, the extrusion process of aluminum alloy profiles is adopted, and the key components such as beams, columns, door frames, vertical ribs and pressure bearing plates are precisely designed. The design of these key components is not arbitrary, but has been repeatedly tested and optimized to meet the strict requirements of pressure bearing, sealing and assembly in all aspects. For example, the beams and columns need to have sufficient strength to bear the pressure inside the oxygen cabin to ensure the stability of the entire structure; the design of the door frame needs to consider the sealing to prevent oxygen leakage, while also facilitating the user to enter and exit; the design of the vertical rib and the pressure bearing plate needs to ensure the stability of the structure while not affecting the reasonable use of the internal space of the oxygen cabin. However, it needs to be noted that the installation precision plays a decisive role in the sealing of the house-shaped oxygen cabin, and is a prerequisite for ensuring its normal function. Especially the assembly of the vertical column and the beam, the assembly quality directly relates to the overall performance of the oxygen cabin. Even the slightest assembly error may cause oxygen leakage during use, which not only reduces the treatment and health care effect, but also may cause safety hazards. At present, whether in large-scale production and assembly in the oxygen cabin plant or in on-site installation in the customer's home environment, a tooling device that meets the specific conditions is urgently needed. In large-scale production in the plant, the tooling device needs to improve the assembly efficiency and ensure the consistency of product quality; in on-site installation in the customer's home environment, the tooling device needs to be convenient to carry and operate, and can adapt to different spaces and installation conditions. Therefore, designing a special assembly tooling for the house-shaped aluminum alloy oxygen cabin has become an important problem to be solved, and the emergence of this tooling will bring great convenience to the production and installation of the oxygen cabin and promote the better role of the oxygen cabin in the field of health care.

[0016] Further, the vertical locking mechanism 302 comprises:

[0017] at least one fastening groove 3021, which is opened on the side surface of the adjusting rod 301 along the vertical direction of the adjusting rod 301;

[0018] at least one vertical locking screw 3022, which is installed on the crossbeam of the support frame 1 and the crossbar 303;

[0019] wherein, by tightening the vertical locking screw 3022 inward, the end face thereof is screwed into the fastening groove 3021 of the adjusting rod 301, thus completing the fixation of the vertical movement of the adjusting rod 301 on the support frame 1.

[0020] Further, the horizontal locking mechanism 304 comprises:

[0021] a sliding groove 3041, which is opened along the length direction of the side surface of the column of the support frame 1;

[0022] a cylindrical groove 3042, which is opened inward on the end face of the crossbar 303;

[0023] a vertical groove 3043, which is opened on the inner surface of the cylindrical groove 3042;

[0027] Among them, a guide block 3047 is provided on the outer surface of the locking block 3046, and a handle 3048 perpendicular to the locking block 3046 is provided at the end of the locking block 3046 away from the spring 3045.

[0028] When the crossbar 303 needs to be locked, the locking block 3046 is pressed into the cylindrical groove 3042, and the handle 3048 is rotated to make the guide block 3047 screw into the arc groove 3044, thereby locking the crossbar 303 onto the column of the support frame 1 and reducing the lateral jump of the adjusting rod 301 on the support frame 1.

[0029] When the handle 3048 is rotated so that the guide block 3047 is rotated out of the arc groove 3044, the locking block 3046 is ejected out of the cylindrical groove 3042 by the action of the spring 3045, so that the crossbar 303 slides in the vertical direction of the column of the support frame 1, and the crossbar 303 is released.

[0030] Furthermore, the pallet 2 is provided with an oxygen chamber crossbeam clamping mechanism 6, which is used to fix the oxygen chamber crossbeam on the pallet 2.

[0031] The oxygen chamber crossbeam clamping mechanism 6 includes:

[0032] At least one mounting plate 601 is fixedly mounted on the side of the support plate 2;

[0033] At least one clamping screw 602 is mounted on the mounting plate 601;

[0034] When it is necessary to fix the oxygen chamber crossbeam to the support plate 2, the end face of the clamping screw 602 is in close contact with the side of the oxygen chamber crossbeam.

[0035] Furthermore, the frame moving mechanism 4 includes:

[0036] At least two mounting brackets 401;

[0037] At least two guide auxiliary wheels 402 are used to assist the support frame 1 in moving along the length of the crossbeam of the oxygen chamber;

[0038] Each of the mounting brackets 401 is disposed opposite to the column of the corresponding support frame 1;

[0039] Each of the guide auxiliary wheels 402 is mounted on a corresponding mounting frame 401; the wheel surface of the guide auxiliary wheel 402 is close to the side surface of the oxygen cabin beam.

[0040] Further, the sliding auxiliary mechanism 5 comprises:

[0041] At least two bases 501 are respectively mounted on the columns of the corresponding support frame 1;

[0042] At least one moving wheel 502 is respectively mounted at the four corners of the corresponding base 501.

[0043] In order to achieve the above-mentioned purpose, the utility model provides following one of the technical schemes: the assembly tool, the tool comprises the support device for beam assembly.

[0044] Further, the tool further comprises a bottom beam one 7, a bottom beam two 8 and a vertical beam 9, the intersection of the bottom beam one 7 and the bottom beam two 8 is provided with vertical beam positioning shoe one 10;

[0045] The top end of the vertical beam 9 is provided with vertical beam positioning shoe two 11;

[0046] Wherein, the support device for beam assembly is located on one of the bottom beam one 7 or the bottom beam two 8; the support device for beam assembly moves linearly along the bottom beam one 7 or the bottom beam two 8;

[0047] The bottom beam one 7, the bottom beam two 8 and the vertical beam 9 are vertically distributed in pairs.

[0048] In the above technical scheme, the assembly tool provided by the utility model is used in the precise assembly work of the house type aluminum alloy oxygen cabin, and the use of the column positioning shoe one is a key link, which provides a solid guarantee for the connection between the bottom beam one, the bottom beam two and the column. The column positioning shoe one is designed ingeniously, and the main structure thereof is made of high-strength alloy and has excellent compression resistance and deformation resistance. During installation, the column positioning shoe one is first accurately placed at the intersection position of the bottom beam one and the bottom beam two marked in advance, the bottom of the positioning shoe one is provided with special clamping grooves that are closely matched with the bottom beam one and the bottom beam two, and after being fastened by high-strength bolts, a very stable connection foundation can be formed. When the column is slowly inserted into the exclusive slot at the top of the column positioning shoe one, the elastic buffer pad inside the slot can adapt to the size of the column, closely match the column and effectively relieve the impact force during installation, further ensuring the stability of the connection.

[0049] More importantly, the column positioning shoe one possesses excellent leveling capabilities. Its internal mechanism is ingeniously designed, featuring a sophisticated leveling system including high-precision fine-tuning bolts and a set of flexibly adjustable shims. On-site, construction workers use a professional electronic level to monitor the levelness of the base beam one, base beam two, and the column in real time. If the level indicates a height discrepancy, workers can immediately adjust the corresponding fine-tuning bolt on the column positioning shoe one. For example, if the level shows the east end of base beam one is slightly higher than the west end, workers can rotate the fine-tuning bolt on the east end of the column positioning shoe one clockwise. Through the threaded transmission, the adjustable shims slowly descend, lowering the height of the east end of base beam one. Through repeated and meticulous fine-tuning, base beam one, base beam two, and the column are all leveled to the ideal state, greatly ensuring their installation accuracy and providing a solid foundation for the subsequent construction of the oxygen chamber.

[0050] In the construction of the oxygen chamber's superstructure, the synergistic effect of the support frame and beam brackets plays an irreplaceable role. The support frame is typically constructed from multiple sections of high-strength aluminum alloy profiles, its structural design fully considering mechanical principles and possessing excellent load-bearing capacity. The beam brackets feature an arc-shaped design adapted to the shape of the crossbeams, and are made of special steel with high toughness and wear resistance. Once the crossbeams are in place, the beam brackets quickly take effect, fitting tightly against the underside of the crossbeams and securely connecting them with bolts, effectively distributing the weight borne by the crossbeams. Simultaneously, the support frame stands firmly on the bottom beams, its top connected to the beam brackets, providing strong support for the crossbeams from below, ensuring the stability of the crossbeams from all directions and preventing deformation, displacement, or other adverse conditions caused by external forces or its own weight during assembly.

[0051] Of particular note is the support frame's flexible position adjustment function. It can be precisely adjusted along the base beam, a feature that greatly facilitates assembly. In actual operation, a unique bracket moving body is installed at the bottom of the support frame. This bracket moving body integrates a precision ball screw transmission system and guide rails. When adjusting the support frame's horizontal position on the base beam, the operator simply operates an external control handle. The handle, through gear transmission, drives the ball screw to rotate, thus propelling the support frame smoothly along the guide rails on the base beam. Furthermore, to further optimize the contact performance between the support frame and the base beam, a roller assembly is cleverly installed at the bottom of the support frame. The roller assembly uses high-strength rubber rollers with a special anti-slip treatment. These rollers fit tightly against the sidewall of the base beam, effectively reducing friction and making movement smoother during support frame movement. They also provide stable support when the support frame is stationary, greatly enhancing the contact between the bottom of the support frame and the sidewall of the base beam, significantly improving the support effect on the crossbeam, and ensuring the high-quality completion of the oxygen chamber assembly.

[0065] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0066] Example 1

[0067] like Figures 1-6 As shown, a support device for beam assembly is used to provide height support and position for the beam during the installation of the oxygen chamber beam. The device includes:

[0068] Supporting framework 1;

[0069] The support plate 2 is located above the support frame 1; the support plate 2 is used to support the crossbeam of the oxygen chamber;

[0070] The height adjustment mechanism 3 is connected to the center of the bottom of the tray 2 and is used to adjust the height of the tray 2 on the support frame 1.

[0071] Furthermore, the support height adjustment mechanism 3 includes:

[0072] Adjusting rod 301, one end of which passes through the crossbeam of support frame 1;

[0073] Specifically, the adjusting rod 301 can move flexibly up and down within the crossbeam of the support frame 1, thereby changing the support height. This adjustability allows the entire support structure to adapt to different usage scenarios and needs. By moving the adjusting rod 301 up and down, precise adjustments to the support height can be achieved quickly and easily, improving the versatility and flexibility of the support structure.

[0074] At least one vertical locking mechanism 302 is provided to fix the vertical movement of the adjusting rod 301 on the support frame 1 after the adjusting rod 301 is adjusted to a specified position; each of the vertical locking mechanisms 302 is located on the crossbeam of the support frame 1.

[0075] Specifically, once the adjusting rod 301 is adjusted to the appropriate height, the vertical locking mechanism 302 can quickly lock it, preventing vertical displacement of the adjusting rod 301 due to external forces (such as equipment vibration or accidental contact) during subsequent use. This ensures the stability of the support height, enabling the support structure to continuously and reliably provide stable support for the equipment. Without the vertical locking mechanism 302, the adjusting rod 301 might move unintentionally, causing changes in the support height, which could affect the normal operation of the installation and even potentially lead to safety accidents.

[0076] Crossbar 303;

[0077] Specifically, the crossbar 303, adjusting rod 301, and the columns of the support frame 1 work together to form a more stable overall structure. The crossbar 303 can distribute the pressure borne by the adjusting rod 301, avoiding excessive local stress, thereby extending the service life of the adjusting rod 301 and the entire support structure. At the same time, the crossbar 303 can also improve the deformation resistance of the support structure, allowing the support structure to maintain good shape and performance even when subjected to large loads.

[0078] At least one lateral locking mechanism 304 is provided to reduce the lateral movement of the adjusting rod 301 on the support frame 1 after the adjusting rod 301 is adjusted to a specified position; each of the lateral locking mechanisms 304 is located between the two ends of the crossbar 303 and the corresponding column of the support frame 1.

[0079] Specifically, the adjusting rod 301 may experience lateral runout due to equipment operation or external environmental influences. This lateral runout not only affects the stability of the support structure but may also lead to increased wear between the adjusting rod 301 and the support frame 1, reducing the equipment's service life. The lateral locking mechanism 304 effectively solves this problem. After the adjusting rod 301 is adjusted to the designated position, it securely fixes it in the lateral direction, reducing the amplitude of lateral runout and thus ensuring the stability and reliability of the support structure. Simultaneously, the lateral locking mechanism 304 also improves the positioning accuracy of the adjusting rod 301, making the adjustment of the support height more precise.

[0080] Furthermore, the vertical locking mechanism 302 includes:

[0081] At least one fastening groove 3021 is formed on the side surface of the adjusting rod 301 along the vertical direction of the adjusting rod 301;

[0082] Specifically, the creation of the fastening groove 3021 requires precise process control. Its width and depth need to be precisely matched to the dimensions of the vertical locking screw 3022 to ensure that the screw can be smoothly screwed in and tightly fitted. Simultaneously, the surface finish of the fastening groove 3021 is also crucial. A smooth surface reduces resistance when the vertical locking screw 3022 is screwed in, preventing wear or jamming caused by surface roughness, thus ensuring the long-term stable operation of the vertical locking mechanism 302. Furthermore, providing multiple fastening grooves 3021 offers more positioning options, allowing the adjusting rod 301 to be reliably fixed in different vertical positions, improving the flexibility and applicability of the support height adjustment.

[0083] At least one vertical locking screw 3022 is mounted on the crossbeam and crossbar 303 of the support frame 1;

[0084] Specifically, the installation position of the vertical locking screw 3022, through design, is mounted on the crossbeam and crossbar 303 of the support frame 1 to ensure more reasonable and stable force transmission when fixing the adjusting rod 301. In terms of material, the vertical locking screw 3022 needs to possess sufficient strength and hardness to withstand the vertical forces that the adjusting rod 301 may generate during use. High-strength metal materials, such as stainless steel or alloy steel, are typically selected to ensure its durability and reliability.

[0085] The vertical locking screw 3022 is screwed inward, and its end face is screwed into the fastening groove 3021 of the adjusting rod 301, thereby fixing the adjusting rod 301 in the vertical movement of the support frame 1.

[0086] Specifically, the vertical locking mechanism 302 works by tightening the vertical locking screw 3022 inward, causing its end face to screw into the fastening groove 3021 of the adjusting rod 301, thereby fixing the adjusting rod 301 in the vertical movement of the support frame 1. When it is necessary to adjust the vertical position of the adjusting rod 301, the vertical locking screw 3022 is first screwed outward, causing its end face to disengage from the fastening groove 3021. At this time, the adjusting rod 301 can move freely vertically within the support frame 1. After the adjusting rod 301 moves to the specified vertical position, the vertical locking screw 3022 is tightened inward again. As the vertical locking screw 3022 is screwed in, its end face gradually embeds into the fastening groove 3021. Due to the constraint effect of the fastening groove 3021 on the end face of the vertical locking screw 3022, the degree of freedom of the adjusting rod 301 in the vertical direction is restricted, thereby achieving reliable fixation of the adjusting rod 301. This fixing method has the advantages of simple operation and good fixing effect. It can effectively prevent the adjusting rod 301 from vertically displacing due to external force during use, thus ensuring the stability and reliability of the support structure.

[0087] Furthermore, the lateral locking mechanism 304 includes:

[0088] The chute 3041 is formed along the length of the column side surface of the support frame 1;

[0089] Specifically, the groove 3041 provides a precise track for the horizontal bar 303 to slide vertically along the column. At the same time, the surface flatness and dimensional accuracy of the groove 3041 are required to be extremely high. The smooth and precisely dimensional groove 3041 reduces friction during the sliding of the horizontal bar 303, ensuring that the horizontal bar 303 can move smoothly on the column and avoid jamming, thereby guaranteeing the flexibility of the entire support structure adjustment process.

[0090] Cylindrical groove 3042 is formed inward on the end face of crossbar 303;

[0091] Specifically, the cylindrical groove 3042 serves as the mounting space for multiple components in the transverse locking mechanism 304. Its inner diameter and depth need to be precisely matched to the dimensions of the spring 3045 and the locking block 3046. A suitable inner diameter ensures that the spring 3045 and the locking block 3046 can freely extend, retract, and move within the cylindrical groove 3042, while an appropriate depth ensures that the spring 3045 has sufficient compression space to achieve the locking and unlocking functions.

[0092] Vertical groove 3043 is formed on the inner surface of cylindrical groove 3042;

[0093] Specifically, its main function is to provide a channel for the vertical movement of the guide block 3047. The width and depth of the vertical groove 3043 need to be adapted to the size of the guide block 3047 to ensure that the guide block 3047 can slide smoothly within it, laying the foundation for subsequent rotation operations.

[0094] An arc-shaped groove 3044 is formed on the inner surface of the cylindrical groove 3042 and communicates with the vertical groove 3043.

[0095] Specifically, the arc design of the arc groove 3044 is key to achieving the locking function of the crossbar 303. Its arc and length design need to be precisely calculated to ensure that the guide block 3047 can be accurately screwed in and out, and can be stably fixed in the arc groove 3044 after being screwed in, thereby achieving reliable locking of the crossbar 303.

[0096] Spring 3045, one end of which is mounted on the bottom of cylindrical groove 3042;

[0097] Specifically, spring 3045 plays a crucial elastic role, providing the extension and retraction force for locking block 3046. When selecting spring 3045, parameters such as its spring constant and maximum compression must be considered. A suitable spring constant ensures that spring 3045 undergoes appropriate deformation under pressure, thereby enabling the locking block 3046 to pop out and retract; while sufficient maximum compression ensures that spring 3045 will not be damaged due to over-compression during the locking process.

[0098] The locking block 3046 is inserted into the cylindrical groove 3042 and connected to the other end of the spring 3045;

[0099] Specifically, the locking and unlocking mechanism of the crossbar 303 is a direct actuator. The shape and size of the locking block 3046 need to match the cylindrical groove 3042 to ensure that it can slide freely within the cylindrical groove 3042. At the same time, the material of the locking block 3046 needs to have a certain strength and wear resistance to withstand the friction and pressure generated during the locking and unlocking process.

[0100] Among them, a guide block 3047 is provided on the outer surface of the locking block 3046, and a handle 3048 perpendicular to the locking block 3046 is provided at the end of the locking block 3046 away from the spring 3045.

[0101] Specifically, the guide block 3047 cooperates with the vertical groove 3043 and the arc groove 3044 to guide the movement direction of the locking block 3046. The handle 3048 provides a convenient operating method for the operator. By rotating the handle 3048, the movement of the guide block 3047 can be easily controlled, thereby realizing the locking and unlocking of the crossbar 303.

[0102] When the crossbar 303 needs to be locked, the locking block 3046 is pressed into the cylindrical groove 3042, and the handle 3048 is rotated to make the guide block 3047 screw into the arc groove 3044, thereby locking the crossbar 303 onto the column of the support frame 1 and reducing the lateral jump of the adjusting rod 301 on the support frame 1.

[0103] When the handle 3048 is rotated so that the guide block 3047 is rotated out of the arc groove 3044, the locking block 3046 is ejected out of the cylindrical groove 3042 by the action of the spring 3045, so that the crossbar 303 slides in the vertical direction of the column of the support frame 1, and the crossbar 303 is released.

[0104] Specifically, when it is necessary to lock the crossbar 303 onto the column of the support frame 1, the operator first presses the locking block 3046 into the cylindrical groove 3042. During this process, the spring 3045 is compressed, storing elastic potential energy. As the locking block 3046 is pressed into the cylindrical groove 3042, the guide block 3047 moves downward along the vertical groove 3043. When the guide block 3047 moves to the connection between the vertical groove 3043 and the arc-shaped groove 3044, the operator rotates the handle 3048, causing the guide block 3047 to screw into the arc-shaped groove 3044. Due to the constraint of the arc-shaped groove 3044, the guide block 3047 is fixed in the arc-shaped groove 3044. At this time, the spring 3045 remains compressed, and the locking block 3046 tightly abuts against the column of the support frame 1, thereby realizing the function of locking the crossbar 303 onto the column of the support frame 1. This locking method effectively reduces the lateral movement of the adjusting rod 301 on the support frame 1, improving the stability of the support structure.

[0105] When it is necessary to loosen the crossbar 303 so that it can slide vertically along the column of the support frame 1, the operator rotates the handle 3048, causing the guide block 3047 to rotate out of the arc-shaped groove 3044. At this time, the guide block 3047 is no longer constrained by the arc-shaped groove 3044, and the spring 3045 releases its stored elastic potential energy, pushing the locking block 3046 out of the cylindrical groove 3042. As the locking block 3046 pops out, the locking state between the crossbar 303 and the column of the support frame 1 is released, and the crossbar 303 can slide freely along the vertical direction of the column of the support frame 1 under the guidance of the slide groove 3041, completing the loosening operation.

[0106] The device also includes a frame moving mechanism 4, which is installed at the bottom of the support frame 1 and is used to move the support frame 1 to a designated position.

[0107] Furthermore, the frame moving mechanism 4 includes:

[0108] At least two mounting brackets 401;

[0109] At least two guide auxiliary wheels 402 are used to assist the support frame 1 in moving along the length of the crossbeam of the oxygen chamber;

[0110] Each of the mounting brackets 401 is disposed opposite to the column of the corresponding support frame 1;

[0111] Each of the guide auxiliary wheels 402 is mounted on a corresponding mounting bracket 401; the wheel surface of the guide auxiliary wheel 402 is in close contact with the side of the oxygen chamber crossbeam.

[0112] Specifically, the mounting brackets 401, through their relative arrangement, ensure that they are evenly distributed on the columns of the supporting frame 1. This guarantees that the forces acting on the supporting frame 1 are evenly distributed during frame movement, preventing structural deformation or damage caused by uneven stress. Strict requirements are placed on the materials and processing techniques used in the manufacturing of the mounting brackets 401. High-strength, corrosion-resistant metal materials, such as stainless steel or aluminum alloy, are typically selected to ensure that the mounting brackets 401 possess sufficient strength and durability to withstand the various forces generated during frame movement. Simultaneously, the surface of the mounting brackets 401 undergoes fine processing to improve the connection stability between them and the columns of the supporting frame 1, preventing loosening or detachment during use.

[0113] The main function of the guide wheel 402 is to assist the support frame 1 in moving smoothly along the length of the oxygen chamber's crossbeam. Each guide wheel 402 is mounted on a corresponding mounting bracket 401, with its wheel surface in close contact with the side of the oxygen chamber's crossbeam. This design allows the guide wheel 402 to provide precise guidance during the movement of the support frame 1, ensuring that the support frame 1 always moves in a straight line along the length of the oxygen chamber's crossbeam, avoiding deviation or swaying. The close contact between the wheel surface of the guide wheel 402 and the side of the oxygen chamber's crossbeam not only provides good guidance but also increases the stability of the support frame 1 during movement. The design and manufacture of the guide wheel 402 also involve considerable consideration. Its wheel body is typically made of materials with good wear resistance and elasticity, such as rubber or polyurethane, to reduce friction with the side of the oxygen chamber's crossbeam while ensuring that it does not damage the crossbeam during contact. In addition, the axle of the guide auxiliary wheel 402 is carefully designed and manufactured to have high-precision rotation performance, which can ensure that the guide auxiliary wheel 402 rotates smoothly and without obstruction, further improving the movement efficiency and stability of the support frame 1.

[0114] The device also includes a sliding auxiliary mechanism 5, which is installed on the inner bottom of the support frame 1 to guide the support frame 1 to move in a specified direction during movement.

[0115] Furthermore, the sliding auxiliary mechanism 5 includes:

[0116] At least two bases 501 are installed on the columns of the corresponding support frame 1;

[0117] At least one movable wheel 502 is installed at the four corners of the corresponding base 501.

[0118] Specifically, the base 501 is the basic support component of the entire sliding auxiliary mechanism 5, and it is installed on the corresponding columns of the support frame 1. The structural characteristics and mechanical properties of the support frame 1 were fully considered during the design and installation of the base 501. By precisely installing the base 501 on the columns of the support frame 1, it is ensured that the entire sliding auxiliary mechanism 5 and the support frame 1 form a stable whole. This allows the base 501 to effectively distribute and transfer forces during the movement of the support frame 1, preventing excessive local stress that could lead to structural damage.

[0119] In terms of materials, the base 501 is typically made of high-strength, high-stability metal materials, such as carbon steel or alloy steel. These materials have excellent compressive and bending resistance, capable of withstanding the weight of the support frame 1 and the equipment it carries, while also resisting various impacts and vibrations generated during movement. In terms of manufacturing process, the surface of the base 501 undergoes fine machining to improve its fit and connection stability with the support frame 1 column. For example, precision machining processes are used to ensure that the mounting holes of the base 501 precisely match the dimensions of the connection points on the support frame 1 column, and then high-strength bolts or welding are used for fixing to ensure a strong connection.

[0120] The movable wheels 502 are key components for enabling the sliding of the support frame 1, and they are respectively installed at the four corners of the corresponding base 501. Installing the movable wheels 502 at the four corners of the base 501 enables the support frame 1 to maintain balance and stability during movement. When the support frame 1 moves, the four movable wheels 502 share the weight of the support frame 1 and can flexibly adjust their direction to ensure that the support frame 1 can move smoothly along the specified direction.

[0121] The design and manufacture of the movable wheel 502 are also very sophisticated. Its wheel body is typically made of materials with good wear resistance and low rolling resistance, such as polyurethane or rubber. These materials not only reduce wear on the movable wheel 502 when in contact with the ground, extending its service life, but also reduce friction during rolling, making the movement of the support frame 1 easier and smoother. Simultaneously, the axle of the movable wheel 502 uses high-precision bearings to ensure that the movable wheel 502 can rotate flexibly and withstand certain axial and radial loads. Furthermore, to improve the guiding performance of the movable wheel 502, some movable wheels 502 may also be equipped with guiding devices, such as guide rims or guide grooves, to ensure that the support frame 1 moves strictly in the specified direction during movement.

[0122] The sliding auxiliary mechanism 5, through the coordinated work of the base 501 and the moving wheel 502, provides reliable sliding guidance and stable support for the support frame 1, enabling it to move accurately and flexibly along the specified direction in various complex working environments, further improving the performance and practicality of the entire device.

[0123] Furthermore, the pallet 2 is provided with an oxygen chamber crossbeam clamping mechanism 6, which is used to fix the oxygen chamber crossbeam on the pallet 2.

[0124] The oxygen chamber crossbeam clamping mechanism 6 includes:

[0125] At least one mounting plate 601 is fixedly mounted on the side of the support plate 2;

[0126] Specifically, the mounting plate 601 serves to provide a stable mounting base for the clamping screw 602. When designing and manufacturing the mounting plate 601, its material and structural strength must be fully considered. Typically, the mounting plate 601 is made of high-strength metal materials, such as stainless steel or carbon steel, to ensure it can withstand the significant pressure generated during the tightening of the clamping screw 602.

[0127] The method of fixing the mounting plate 601 is also very important. Generally, it is firmly installed on the side of the support plate 2 by welding or bolting. Welding provides high connection strength, making the mounting plate 601 and the support plate 2 form a whole, enhancing the stability of the structure; while bolting has the advantage of easy disassembly and replacement, making it convenient to operate the mounting plate 601 during later maintenance or adjustment.

[0128] The number and distribution of mounting plates 601 need to be rationally designed based on the size, weight, and actual stress conditions of the oxygen chamber crossbeam. Multiple mounting plates 601 can be evenly distributed on the side of the support plate 2 to ensure uniform distribution of the clamping force on the oxygen chamber crossbeam and avoid excessive local stress that could damage the oxygen chamber crossbeam.

[0129] At least one clamping screw 602 is mounted on the mounting plate 601;

[0130] Specifically, the clamping screw 602 is typically made of high-strength alloy steel to ensure sufficient strength and hardness to withstand large tightening forces without deformation or damage. When installing the clamping screw 602, it is essential to ensure a good fit between it and the threaded hole on the mounting plate 601. The precision and surface quality of the threads directly affect the tightening effect and service life of the clamping screw 602.

[0131] When it is necessary to fix the oxygen chamber crossbeam to the support plate 2, the end face of the clamping screw 602 is in close contact with the side of the oxygen chamber crossbeam.

[0132] Specifically, when it is necessary to fix the oxygen chamber crossbeam to the tray 2, the operator rotates the clamping screw 602, causing its end face to gradually approach and eventually fit tightly against the side of the oxygen chamber crossbeam. As the clamping screw 602 is tightened continuously, the pressure it exerts on the oxygen chamber crossbeam gradually increases, thereby achieving the purpose of firmly fixing the oxygen chamber crossbeam to the tray 2.

[0133] In actual operation, to ensure the clamping effect, it is necessary to use appropriate tools to tighten the clamping screw 602 to the specified torque value. At the same time, it is also necessary to check the tightness of the clamping screw 602 regularly to prevent the screw from loosening due to vibration or other reasons, which would affect the fixing effect of the oxygen chamber beam.

[0134] In summary, the oxygen chamber crossbeam clamping mechanism 6, through the synergistic action of the mounting plate 601 and the clamping screws 602, can effectively fix the oxygen chamber crossbeam onto the support plate 2, providing a reliable guarantee for the stable operation of the entire device.

[0135] Example 2

[0136] like Figures 7-10 As shown, the assembly fixture includes the beam assembly support device described in Embodiment 1 above.

[0137] Furthermore, the tooling also includes a bottom beam 7, a bottom beam 8, and a vertical beam 9, with a vertical beam positioning shoe 10 provided at the intersection of the bottom beam 7 and the bottom beam 8.

[0138] The top of the vertical beam 9 is provided with a vertical beam positioning shoe 2 11;

[0139] Among them, the support device for assembling the crossbeam is located on one of the bottom beam 7 or the bottom beam 8; the support device for assembling the crossbeam moves linearly along the bottom beam 7 or the bottom beam 8.

[0140] The bottom beam 7, bottom beam 8, and vertical beam 9 are arranged in pairs perpendicularly.

[0141] Specifically, the tooling, in addition to the support device for assembling the crossbeams, also includes key components such as bottom beam 7, bottom beam 8, and vertical beam 9. Bottom beams 7 and 8, as the basic support structures of the tooling, have undergone careful design and layout. At the intersection of bottom beams 7 and 8, a vertical beam positioning shoe 10 is specially installed. The vertical beam positioning shoe 10 plays a crucial role in precisely fixing the position of the vertical beam 9; it acts like a precise positioning anchor point, ensuring that the vertical beam 9 can be accurately installed in the predetermined position, avoiding structural instability caused by installation deviations.

[0142] A positioning shoe 2 11 is installed at the top of the upright beam 9. The positioning shoe 2 11 works in conjunction with the positioning shoe 10 to further improve the stability and accuracy of the upright beam 9 installation. During the oxygen chamber assembly process, the upright beam 9 undertakes the important task of connecting various parts and building the overall frame, while the positioning shoe 2 11 ensures the precise vertical positioning of the upright beam 9, making the entire tooling structure more stable and reliable.

[0143] It is worth mentioning the position and movement method of the crossbeam assembly support device. The crossbeam assembly support device is located on either bottom beam 7 or bottom beam 8, and it has the ability to move linearly along either bottom beam 7 or bottom beam 8. This movable design brings great flexibility to the tooling. In actual assembly, according to different assembly requirements and the structural characteristics of the oxygen chamber, operators can easily move the crossbeam assembly support device to the appropriate position, thereby providing optimal support and positioning for the crossbeam assembly. This not only improves assembly efficiency but also reduces the workload of manual adjustments and lowers the possibility of human error.

[0144] From an overall structural layout perspective, bottom beam 7, bottom beam 8, and vertical beam 9 are arranged in pairs at perpendicular intervals. This vertical arrangement is based on the actual assembly requirements and mechanical principles of the aluminum alloy oxygen chamber. This pairwise perpendicular structure maximizes the stability and load-bearing capacity of the tooling, ensuring its integrity and stability even when bearing the weight of the various components of the oxygen chamber and external forces during assembly. Simultaneously, this regular vertical layout facilitates the manufacturing and installation of the tooling, improving production efficiency and assembly accuracy.

[0145] In summary, this assembly fixture, by integrating the crossbeam assembly support device and components such as bottom beam 7, bottom beam 8, and vertical beam 9, and relying on the precise positioning function of vertical beam positioning shoe 10 and vertical beam positioning shoe 211, as well as the movable characteristics and reasonable vertical structural layout of the crossbeam assembly support device, provides an efficient, stable, and precise working platform for the assembly of the room-type aluminum alloy oxygen chamber, greatly improving the quality and efficiency of oxygen chamber assembly.

[0146] Example 3

[0147] A method for assembling an aluminum alloy oxygen chamber, applied to the assembly fixture described in Example 2 above, includes:

[0148] S1, bottom beam 7, bottom beam 8 and vertical beam 9 are arranged in pairs perpendicularly to form the apex of a rectangle;

[0149] Specifically, during operation, high-precision measuring tools, such as laser rangefinders and levels, are required to ensure that the verticality error between bottom beam 7, bottom beam 8, and vertical beam 9 is controlled within a minimal range. For example, the verticality error should be controlled to no more than 0.5 millimeters per meter to ensure the accuracy of subsequent assembly. Simultaneously, these components undergo rigorous quality inspection to check for defects such as deformation and cracks; only qualified components can be used. During installation, multiple people must work together, using appropriate hoisting equipment to precisely install vertical beam 9 at the intersection of bottom beam 7 and bottom beam 8, forming a stable rectangular apex structure to provide stable support for subsequent assembly work.

[0150] S2. Move the crossbeam assembly support device along the bottom beam 7 or bottom beam 8 in a straight line to the designated position.

[0151] Specifically, before relocation, operators must determine the installation position of the crossbeams based on the design drawings of the aluminum alloy oxygen chamber, thereby calculating the distance and direction the support device needs to be moved. During the relocation, it is crucial to ensure the support device moves smoothly along a straight line, avoiding any deviation. Guide rails and graduated markings can be installed on bottom beams 7 and 8 to allow operators to accurately control the movement of the support device. Simultaneously, a dedicated person should supervise the process to ensure safety and accuracy.

[0152] S3. Adjust the tray 2 to the specified height using the height adjustment mechanism 3;

[0153] Specifically, during the adjustment process, the height adjustment mechanism 3 should be operated slowly, and a height measuring instrument should be used for real-time monitoring to ensure that the height error of the pallet 2 is controlled within the allowable range. For example, the height error should be controlled within ±1 mm. After the adjustment is completed, the height adjustment mechanism 3 should be initially fixed to prevent the height of the pallet 2 from changing during subsequent operations.

[0154] S4. After the adjusting rod 301 has been adjusted to the designated position by the vertical locking mechanism 302, the vertical movement of the adjusting rod 301 on the support frame 1 is fixed.

[0155] Specifically, once the adjusting rod 301 reaches the designated height, the operator must use a specialized tool, such as a wrench, to tighten the vertical locking screw 3022 inwards, ensuring its end face is accurately screwed into the fastening groove 3021 of the adjusting rod 301. During tightening, care must be taken to apply even pressure to avoid damaging the fastening groove 3021 or the vertical locking screw 3022 due to excessive force. After tightening, a vertical tensile test must be performed on the adjusting rod 301 to ensure that it does not undergo vertical displacement under normal operating conditions.

[0156] S5. After the adjusting rod 301 has been adjusted to the designated position by the lateral locking mechanism 304, the lateral runout of the adjusting rod 301 on the support frame 1 is reduced.

[0157] Specifically, the operator first presses the locking block 3046 into the cylindrical groove 3042, at which point the spring 3045 is compressed, storing elastic potential energy. Then, the operator rotates the handle 3048, causing the guide block 3047 to move along the vertical groove 3043 to the point of connection with the arc-shaped groove 3044. The operator continues to rotate the handle 3048, causing the guide block 3047 to screw into the arc-shaped groove 3044. During operation, it is essential to ensure that the guide block 3047 is fully screwed into the arc-shaped groove 3044 and that the locking block 3046 firmly abuts against the column of the support frame 1. After completing the operation, a lateral sway test is performed on the adjusting rod 301 to check if its lateral runout meets the requirements.

[0158] S6. After placing the crossbeam to be installed on the pallet 2, the side of the crossbeam to be installed is positioned and pressed by the oxygen chamber crossbeam pressing mechanism 6.

[0159] Specifically, when placing the crossbeam, hoisting equipment should be used to place the crossbeam stably on the support plate 2, ensuring that the crossbeam's position conforms to the design requirements. Then, the operator rotates the clamping screw 602, gradually bringing its end face closer to and tightly against the side of the oxygen chamber crossbeam. During the tightening of the clamping screw 602, the operation should be carried out in a symmetrical sequence to ensure that the crossbeam receives uniform pressure. At the same time, feeler gauges and other tools should be used to check the fit between the crossbeam and the support plate 2, ensuring that the fit gap does not exceed 0.2 mm, to guarantee the positioning accuracy and clamping effect of the crossbeam.

[0160] S7. One end of the crossbeam to be installed is connected to the vertical beam 9 through the vertical beam positioning shoe 2 11;

[0161] Specifically, before connection, the connection area between the upright beam positioning shoe 21 and the upright beam 9 should be cleaned and polished to remove surface impurities and oxide layers, ensuring a firm connection. Then, use appropriate connecting bolts to connect the crossbeam and the upright beam 9. During bolt tightening, operate according to the specified torque value to ensure reliable connection. After connection, visually inspect the connection area to check for gaps, deformation, or other problems.

[0162] S8. Repeat S2-S7 until the installation of the aluminum alloy oxygen chamber is completed.

[0163] Specifically, during each repetitive operation, a quality inspection must be conducted on the completed sections to ensure that the installation of each crossbeam meets design requirements. Simultaneously, attention must be paid to the connection sequence and quality between the crossbeams to guarantee the structural stability and sealing of the entire aluminum alloy oxygen chamber. Near the end of the installation process, a comprehensive inspection and commissioning of the entire oxygen chamber must be performed to ensure its normal operation.

[0164] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
