Description

Technical Field

[0001] This invention relates to the technical field of hangar doors, and more specifically to a sliding hangar door. Background Technology

[0002] Sliding hangar doors are a specialized type of large industrial sliding door, primarily used in hangar settings. Their core advantages include large span, high load-bearing capacity, and an opening mechanism that doesn't occupy vertical space. They are mainly used in the aerospace industry, large industrial plants and warehouses, and other special industrial scenarios. Sliding hangar doors generally consist of multiple door units linked by tracks, a transmission system, and a control system, sliding horizontally along the wall to open and close.

[0003] Patent document CN115324457B discloses a three-section sliding door, including a guide rail component and a door body component. The guide rail component includes a lower fixed guide rail, a lower movable guide rail, and a support assembly. The lower fixed guide rail is mounted on the bottom frame mounting surface. The support assembly includes an elastic element mounted on the bottom of the lower movable guide rail. One end of the elastic element is fixedly mounted on the bottom frame mounting surface, and the other end is mounted on the lower movable guide rail. By pressing against the elastic element, it is compressed, causing the lower movable guide rail to move downward relative to the lower fixed guide rail. The door body component is mounted on the rail surface of the guide rail component. The three-section sliding door also includes a limiting assembly. The support assembly includes a support member that supports the lower movable guide rail via the elastic element. The limiting assembly restricts the position of the support member, which has a first groove and a second groove. The limiting assembly includes a movable top member. By pressing down the lower movable guide rail, the door body component can be detached from the upper frame of the door frame.

[0004] However, this solution also has the following problems: in application scenarios with large spans, it faces significant structural stability and operational reliability issues during actual use. Due to the significantly increased weight of the large-span door, all the load is directly concentrated on the guide rail components, which consist of a fixed lower guide rail, a movable lower guide rail, and support components, far exceeding the load-bearing capacity of guide rails for conventional span doors. During daily pushing and pulling operations, the uneven distribution of contact stress between the door and the guide rail, coupled with the repeated compression and rebound of the elastic elements in the support components, easily causes continuous micro-vibrations along the longitudinal direction of the door. In harsh outdoor environments such as strong winds, the lateral thrust of airflow on the large-span door leaf further exacerbates this problem, causing the door leaf to shake violently, which in turn causes high-frequency impacts on the connection between the guide rail and the door. Simultaneously, the relatively high center of gravity of the large-span door makes it difficult for the door to maintain stability in both pushing, pulling, and closing states, and it will continue to vibrate due to residual stress and external environmental disturbances.

[0005] When the above problems persist for a long time, they will not only cause continuous stress on the overall structure of the hangar where the door is installed, causing structural sagging or deformation, but also accelerate the wear and damage of various components such as guide rails, support components, and limit components. At the same time, they will cause the door to not close properly, seriously affecting the performance and service life of the sliding door. Summary of the Invention

[0006] This invention provides a sliding hangar door, aiming to solve the problem in related technologies that large-span sliding doors are prone to structural damage or incomplete closure due to vibration and swaying.

[0007] The present invention relates to a sliding hangar door, comprising a door body assembled within a door frame, wherein an adjustment assembly and a drive assembly are provided on the door frame; the adjustment assembly includes: a connecting frame fixed to the upper end of the door body, and a pair of adjustment frames slidably mounted on the door frame, the sliding direction of the adjustment frames being perpendicular to the sliding direction of the door body; the drive assembly is connected to the adjustment frames to drive the two adjustment frames to move in opposite directions; the adjustment frames include a support portion and a pushing portion, the support portion of the two adjustment frames being located in the area between the two pushing portions; the connecting frame includes: a pair of mating portions adapted to the two support portions respectively, and a pair of abutting portions adapted to the two pushing portions respectively; a guide wheel is provided at the lower end of the door body to cooperate with the door frame; when the door body moves, the drive assembly drives the two adjustment frames to move away from each other, so that the support portion and the mating portion cooperate to support the upper end of the door body; after the door body stops moving, the drive assembly drives the two adjustment frames to move closer to each other, so that the pushing portion and the abutting portion abut and lift the abutting portion upward, thereby releasing the pressure between the guide wheel and the door frame and fixing the door body.

[0008] Its effect is that the drive assembly drives the support part and the mating part to cooperate, so as to support the upper part of the door when the door moves, reducing the shaking of the door during movement. Similarly, when the door is stationary and closed, the drive assembly drives the two adjusting frames to move closer together, so that the pushing part and the abutting part can fit together through the inclined structure, converting the horizontal driving force into the vertical upward lifting force, forming a stable support for the door, effectively distributing the weight of the door itself, and significantly reducing the contact pressure between the guide wheel and the frame at the bottom of the door. This avoids the deformation, wear, jamming and other failures of the guide wheel, frame and other components due to long-term pressure. At the same time, through the cooperation of the support part and the mating part, and the cooperation of the pushing part and the abutting part, the wear of the door structure is reduced, the stress state of the door in different states is optimized, and the shaking amplitude of the door under external force disturbance is suppressed, which significantly improves the sealing and closing effect of the door and blocks the influence of external environmental factors on the internal space of the hangar.

[0009] Preferably, the two mating parts and the two abutting parts are in two groups, with each group of mating parts and abutting parts being integrally arranged, and each group of mating parts and abutting parts being located between the support part and the pushing part on the corresponding adjustment frame.

[0010] The effect is that, by setting two sets of mating parts and abutting parts, when the door moves, the two supporting parts and the two mating parts cooperate simultaneously to improve the stability of the door when it moves. When the door is stationary, the two pushing parts cooperate with the abutting parts to make the upper part of the door evenly stressed, thereby improving the overall stability of the door.

[0011] Preferably, a rotating wheel is rotatably provided on the mating part, the support part is arranged in the vertical direction, the axis of rotation of the rotating wheel is arranged in the vertical direction, and the mating part abuts against the support part through the rotating wheel.

[0012] Its effect is that by setting a rotating wheel in the mating part, the sliding friction between the support part and the mating part is converted into rolling friction. This not only provides stable support and limit for the upper part of the door, but also effectively reduces the frictional resistance during the movement of the door, ensuring that the door slides smoothly along the preset trajectory, avoiding the problems of deviation and shaking caused by unstable support, and reducing the wear and fatigue damage of the door structure and related components caused by repeated impacts and friction during the movement.

[0013] Preferably, the pushing part has a first inclined surface on the side near the abutting part, and the abutting part has a second inclined surface on the side near the pushing part. The upper end of the first inclined surface is inclined in the direction away from the support part, and the second inclined surface is inclined in the same direction as the first inclined surface. When the first inclined surface and the second inclined surface abut together, the abutting part is supported.

[0014] Its effect is that by setting a first inclined surface on the pushing part and a second inclined surface on the abutting part, when the pushing part approaches the abutting part, the first inclined surface and the second inclined surface cooperate to lift the abutting part, release the pressure on the guide wheel, improve the stability of the door in a static state, and reduce the phenomenon of damage to the guide wheel.

[0015] Preferably, the drive assembly includes: a drive component, a drive screw connected to the output end of the drive component, the drive screw being arranged along the sliding direction of the adjustment frame, the drive screw having two threaded grooves with opposite thread directions, the adjustment frame having drive blocks, and the drive blocks on the two adjustment frames respectively engaging with the two threaded grooves.

[0016] Its effect is that when the position of the adjustment frame needs to be adjusted, the driving component drives the driving screw to rotate. The driving screw drives the two adjustment frames to move simultaneously through the threaded grooves with opposite thread directions at both ends. The two adjustment frames move in opposite directions, causing them to move closer or further away from each other, thereby driving the support part to cooperate with the mating part or driving the pushing part to cooperate with the abutting part.

[0017] Preferably, there are multiple sets of adjustment frames, with two adjustment frames forming a set, and multiple sets of thread grooves corresponding one-to-one with the multiple sets of adjustment frames, with two thread grooves of opposite thread directions forming a set.

[0018] Its effect is that when the drive screw rotates, multiple sets of threaded grooves can simultaneously drive multiple sets of adjustment frames to move, thereby synchronously supporting and cooperating with multiple door bodies and ensuring that the force conditions of multiple door bodies are consistent.

[0019] Preferably, a slot is provided at the bottom of the door body, and an installation plate is fixed in the slot by bolts. Guide wheels are rotated and assembled on the installation plate, and multiple guide wheels are arranged on the installation plate along the sliding direction of the door body.

[0020] The effect is that the mounting plate is fixed to the door body with bolts so that it can be disassembled to maintain or replace the guide wheels.

[0021] Preferably, a support frame is provided at the top of the gantry, and a support block is provided on the side of the adjustment frame away from the gantry, with the support block slidingly locked inside the support frame.

[0022] The effect is that by setting a support frame on the gantry and setting a support block on the adjustment frame that slides with the support frame, the stability of the adjustment frame when it moves is improved.

[0023] Preferably, the bottom of the gantry is provided with multiple slide rail grooves, each corresponding to a different door body. The guide wheel cooperates with the slide rail grooves, and the arrangement direction of the multiple slide rail grooves is perpendicular to the drive screw.

[0024] Preferably, multiple rotating wheels are provided, and the multiple rotating wheels are arranged on the mating part along the sliding direction of the door body.

[0025] Beneficial effects:

[0026] This invention constructs a collaborative support system for both moving and stationary door conditions by specifically configuring a support part that matches the mating part and a pushing part that matches the abutting part. The displacement of the adjustment frame can drive the support part and the mating part to form an abutting engagement, or drive the pushing part and the abutting part to engage, thereby achieving flexible switching between the two support modes. When the door is in a moving state, the support part and the mating part abut against each other, and the rolling support structure provides stable upper support and limit for the door, ensuring the accuracy of the trajectory during the sliding process and avoiding problems such as deviation and swaying during movement; when the door has completed its movement and is in a stationary closed state, the pushing part and the abutting part form an inclined engagement, converting the horizontal driving force into a vertical lifting force to stably lift the door. This invention relies on the separate working condition cooperation design of the support part-fitting part and the pushing part-abutting part to improve the stability of the door in both moving and stationary states. It effectively suppresses the shaking amplitude of the door under external force disturbance, reduces fatigue damage and component wear caused by repeated shaking of the door structure, and significantly optimizes the sealing and closing effect of the door, thereby improving the overall operational reliability and service life.

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1 to 8As shown, the sliding hangar door of the present invention comprises a door frame 1 and door bodies 2 adapted to be installed inside the door frame 1. The bottom of the door frame 1 is provided with a plurality of slide rail grooves 12, and the slide rail grooves 12 are arranged in a parallel manner along the length direction of the door frame 1 to ensure that the extension path of the slide rail grooves 12 is consistent and there is no cross interference. Matching the slide rail grooves 12, there are also a plurality of door bodies 2, and each door body 2 and the slide rail groove 12 are assembled in a one-to-one correspondence. Each door body 2 is embedded in the corresponding slide rail groove 12 and can slide freely along the extension direction of the slide rail groove 12, so that each door body 2 can complete the sliding action on the parallel tracks.

[0039] When the hangar door needs to be opened, the operator can push the door body 2, causing each door body 2 to move to one side along its corresponding slide rail 12. Through the staggering and overlapping of the door bodies 2, the overall space occupied by the hangar door is significantly reduced, thus enabling the door to open. When the hangar door needs to be closed, the operator pushes the door body 2 in the opposite direction, causing each door body 2 to move to the other side along its slide rail 12. Through the sequential unfolding and splicing of the door bodies 2, a closed door body structure is formed, thus closing the hangar door. The overlapping or unfolding of multiple door bodies 2 meets the opening and closing requirements of large-span hangars.

[0040] Reference Figure 2 , Figure 4 , Figure 5 The lower end of the door body 2 is equipped with a guide wheel 7, which cooperates with the slide rail groove 12 on the door frame 1. That is, the door body 2 cooperates with the slide rail groove 12 through the guide wheel 7. When the door body 2 moves, the guide wheel 7 rotates accordingly to guide the door body 2 to move within the slide rail groove 12. The rolling motion of the guide wheel 7 replaces the traditional sliding friction contact, thereby greatly reducing the frictional resistance encountered by the door body 2 during its movement within the slide rail groove 12. This not only allows the operator to adjust the opening and closing position of the door body 2 more effortlessly, but also effectively constrains the movement trajectory of the door body 2 through the limiting cooperation between the guide wheel 7 and the slide rail groove 12, avoiding instability such as deviation and shaking during the movement of the door body 2, and significantly improving the stability and reliability of the overall movement of the door body 2.

[0041] Reference Figure 3 , Figure 4 , Figure 5 An adjustment component 3 and a drive component 4 are provided on the gantry 1. The adjustment component 3 and the drive component 4 work together to reduce the shaking of the door body 2 when the door body 2 moves, and to improve its stability after the door body 2 stops moving, so as to reduce the damage to the door body 2 and ensure the closing effect of the hangar door.

[0042] Reference Figure 3 , Figure 4 , Figure 5The adjustment component 3 includes a connecting frame 5 and an adjustment frame 6. The connecting frame 5 is fixedly connected to the upper end of the door body 2, specifically by bolts and nuts. The adjustment frame 6 is slidably mounted on the door frame 1, and there is a pair of adjustment frames 6. The sliding direction of the adjustment frame 6 is perpendicular to the sliding direction of the door body 2. The driving component 4 is connected to the adjustment frame 6 to drive the two adjustment frames 6 to move synchronously in opposite directions, so that the two adjustment frames 6 can move closer or further away synchronously. The adjustment frame 6 includes a support part 61 and a pushing part 62, which are integrally set. The support parts 61 of the two adjustment frames 6 are located in the middle area between the two pushing parts 62, forming a "middle support, two-sided pushing" structural layout. The connecting frame 5 is correspondingly provided with a pair of mating parts 51 that are adapted to the support parts 61, and a pair of abutting parts 52 that are adapted to the pushing parts 62.

[0043] When the door 2 needs to be moved, the drive assembly 4 drives the two adjustment frames 6 to move away from each other in opposite directions. At this time, the support part 61 of the adjustment frame 6 will gradually approach and cooperate with the mating part 51 of the connecting frame 5. The support part 61 provides a stable support force for the connecting frame 5 and the upper end of the door 2 through contact with the mating part 51. Combined with the rolling support of the guide wheel 7 at the lower end of the door 2, the door 2 is subjected to balanced force at both ends during the movement, avoiding the door 2 from tilting or getting stuck due to force on one side, and ensuring the stability and smoothness of the movement of the door 2.

[0044] After the door 2 completes its movement and stops, the drive assembly 4 drives the two adjusting frames 6 to move closer to each other in opposite directions. During this process, the support part 61 separates from the mating part 51, and at the same time, the pushing part 62 of the adjusting frame 6 gradually approaches and forms a tight surface contact with the abutting part 52 of the connecting frame 5. As the adjusting frame 6 continues to move, the pushing part 62 applies an upward lifting force to the abutting part 52 through the abutting surface. This lifting force is transmitted to the entire door 2 through the connecting frame 5, providing an upward lifting force to the door 2. This lifting force directly changes the force state between the lower guide wheel 7 and the door frame 1, effectively releasing the pressure between the guide wheel 7 and the door frame 1, and preventing the guide wheel 7 from being damaged due to continuous force in a long-term static state. Deformation or wear; at the same time, the tight contact between the pushing part 62 and the abutting part 52 will form a lateral limiting force. Combined with the support part 61 and the mating part 51, the door body 2 is reliably fixed from multiple dimensions, including the upper and lower and lateral dimensions. This greatly improves the structural stability of the door body 2 when it is stationary, and avoids the displacement or shaking of the door body 2 due to external vibration, wind load and other factors. It can not only reduce the wear of the sliding components and the structure of the door body 2 during the movement of the door body 2, but also ensure that the splicing gap between each door body 2 is uniform and tight after the door body 2 is closed, and avoid the failure of the seal due to the displacement of the door body 2. This ensures the closing effect of the hangar door and effectively blocks the impact of external wind, sand, rain and noise on the internal environment of the hangar.

[0045] The two mating parts 51 and the two abutting parts 52 are divided into two independent structural units. The mating parts 51 and abutting parts 52 in each structural unit are integrally set. Each structural unit corresponds to two adjusting frames 6, and the mating parts 51 and abutting parts 52 in each structural unit are located between the support part 61 and the pushing part 62 on the corresponding adjusting frame 6, forming a continuous structural sequence of "support part 61 - mating part 51 - abutting part 52 - pushing part 62". When the two adjusting frames 6 are driven away from each other, the displacement of the adjusting frame 6 will synchronously drive its support part 61 to engage with the mating part 51 on the corresponding side; when the two adjusting frames 6 are driven closer to each other, the opposing displacement of the adjusting frames 6 will drive the pushing part 62 to form a tight abutting engagement with the abutting part 52 on the corresponding side, so as to apply an upward lifting force to the door body 2. In particular, after the two sets of push parts 62 are assembled, their spatial positions are located on the outer side of the corresponding abutment part 52. This layout design can ensure that when the push part 62 cooperates with the abutment part 52, it can apply a stable and uniform upward lifting force to the door body 2.

[0046] Reference Figure 3 , Figure 5 , Figure 7 The mating part 51 is rotatably equipped with several rotating wheels 511. The support part 61 is arranged vertically, and the axis of rotation of the rotating wheels 511 is also arranged vertically. Each rotating wheel 511 is arranged sequentially along the sliding trajectory of the door body 2. When the two adjusting frames 6 move away from each other, the support part 61 is driven to move closer to the mating part 51. The mating part 51 maintains rolling contact with the support part 61 through these rotating wheels 511, thereby converting the traditional sliding friction into rolling friction, greatly reducing the frictional resistance between the door body 2 and the support part 61. This allows the operator to more easily and smoothly make precise adjustments to the installation position of the door body 2, effectively improving the efficiency and accuracy of the door body 2 assembly operation.

[0047] Reference Figure 5 The pushing part 62 has a continuous and smooth inclined surface 621 integrally formed on the side facing the abutting part 52. The abutting part 52 and the pushing part 62 are respectively provided with an inclined surface 521 that is adapted to the inclined surface 621. The upper end of the inclined surface 621 extends at a preset angle in the direction away from the support part 61. The inclined angle of the inclined surface 521 is the same as that of the inclined surface 621, so that the two can achieve seamless contact when they abut. Based on this adapted inclined surface structure, the inclined surface 621 is the abutting surface of the pushing part 62. When the pushing part 62 and the abutting part 52 come into contact with each other, the guiding effect of the inclined surface can form a lifting effect on the abutting part 52.

[0048] As the pushing part 62 approaches the abutting part 52 in the horizontal direction, the first inclined surface 621 and the second inclined surface 521 come into contact and form a tight abutting fit. At this time, the horizontal driving force applied by the pushing part 62 will be decomposed by the matching inclined surface structure. Part of the driving force maintains the fit between the pushing part 62 and the abutting part 52, while the other part is converted into a vertically upward lifting force. This lifting force acts directly on the door body 2 through the connecting frame 5, applying a vertically upward lifting force to the door body 2. This lifting action can effectively reduce the pressure of the door body 2's own weight on the contact point between the guide wheel 7 and the gantry 1, avoiding problems such as overload of the guide wheel 7 bearing and stress concentration at the contact point of the gantry 1, and significantly reducing the occurrence of damage to parts such as wear and deformation of the guide wheel 7 and local dents of the gantry 1; at the same time, after the door body 2 is stably lifted, it can effectively avoid the shaking and displacement of the door body 2 caused by the gap between the guide wheel 7 and the gantry 1 or uneven force, further improving the structural stability and assembly reliability of the door body 2 in a static state.

[0049] In this embodiment, when the door 2 is stationary after being moved, the cooperation between inclined plane 1 621 and inclined plane 2 521 only provides stable support for the door 2 and does not drive the door 2 to produce vertical displacement. The tight contact between the two is essentially to effectively reduce the pressure load on the guide wheel 7 below the door 2 by sharing part of the weight of the door 2. During this process, the guide wheel 7 always maintains a stable contact with the inner wall of the slide rail groove 12, and there is no separation or intermittent separation. Therefore, since the guide wheel 7 below the door 2 is still engaged with the slide rail groove 12 when supporting and fixing the upper part of the door 2, the stability of the lower part of the door 2 can be guaranteed, thereby ensuring the overall stability of the door 2.

[0050] Reference Figure 4 , Figure 5 , Figure 8 The bottom of the door body 2 is provided with a slot 11. Inside the slot 11, a mounting plate 8 is fastened to the inside by a bolt assembly. Multiple guide wheels 7 are sequentially mounted on the mounting plate 8 along the sliding direction of the door body 2, forming a rolling support structure that matches the sliding trajectory of the door body 2. This bolt-fastened connection method can achieve a stable assembly between the mounting plate 8 and the bottom of the door body 2, while also providing convenient disassembly. When the guide wheels 7 are worn, malfunction, or require maintenance or replacement, the operator only needs to unscrew the connecting bolts to remove the mounting plate 8 along with the guide wheels 7 from the slot 11 at the bottom of the door body 2. No additional disassembly or modification of the door body 2 is required, which greatly reduces the difficulty of maintaining the guide wheels 7 and improves the efficiency of the equipment's later operation and maintenance.

[0051] To further improve the ease of disassembling the mounting plate 8, during the disassembly operation, the existing abutment and support base of inclined plane 1 621 and inclined plane 2 521 can be used to drive the two sets of adjusting frames 6 to move closer together, causing the pushing part 62 to move continuously towards the abutment part 52, thereby causing inclined plane 1 621 and inclined plane 2 521 to form contact and cooperation at different positions. During this process, the continuous advancement of the pushing part 62 will be converted into an upward driving force through the guiding effect of the inclined plane, causing the door body 2 to be slightly raised in the vertical direction until the guide wheel 7 at the bottom of the door body 2 is completely separated from the inner wall of the slide rail groove 12 and is in a suspended state. This completely releases the support and restriction of the guide wheel 7 on the door body 2, so that the mounting plate 8 and the guide wheel 7 on it can be smoothly removed from the slot 11 at the bottom of the door body 2.

[0052] Reference Figure 2 , Figure 3 , Figure 5 The drive assembly 4 includes a drive component 41 and a drive screw 42. The drive component 41 is a motor, which is fixedly mounted on the gantry 1. The drive screw 42 is rotatably mounted on the top of the gantry 1 and located above the adjusting frame 6. The power output end of the drive component 41 is equipped with a transmission belt 411, which is connected to the drive screw 42. The drive component 41 can drive the drive screw 42 to rotate synchronously through the transmission action of the transmission belt 411. The arrangement direction of the drive screw 42 is consistent with the sliding direction of the adjusting frame 6.

[0053] Reference Figure 3 , Figure 5 Two threaded grooves 421 of the same length but opposite directions are machined on the drive screw 42 along its axial direction. The pitch and thread profile parameters of the two threaded grooves 421 are the same. A drive block 422 is provided above each of the two adjusting frames 6. The end of the drive block 422 has an internal threaded hole. The drive block 422 of the two adjusting frames 6 forms a one-to-one threaded engagement relationship with the two reverse threaded grooves 421 on the drive screw 42. When the drive component 41 starts and drives the drive screw 42 to rotate through the transmission belt 411, based on the meshing action of the two reverse threaded grooves 421 and the drive block 422, the two adjusting frames 6 will synchronously slide in opposite directions or in a straight line along the axial direction of the drive screw 42, and their moving speed and displacement will always be consistent, thereby realizing the synchronous adjustment of the distance between the two adjusting frames 6.

[0054] Reference Figure 3The adjustment frame 6 is provided in multiple sets, with two adjustment frames 6 forming a set. Correspondingly, the drive screw 42 is machined with multiple sets of threaded grooves 421 structures corresponding one-to-one with the number of adjustment frames 6. Each set of threaded grooves 421 contains two threaded segments with opposite directions of rotation, and the specifications of each set of threaded grooves 421 are consistent. Furthermore, the arrangement direction of each slide rail groove 12 is perpendicular to the axis of the drive screw 42. By integrating multiple sets of threaded grooves 421 corresponding one-to-one with the adjustment frames 6 on the drive screw 42, when the drive screw 42 is driven to rotate by the drive component 41, the engagement of each set of threaded grooves 421 with the corresponding adjustment frame 6 drive block 422 can synchronously drive multiple sets of adjustment frames 6 to adjust their positions in opposite directions, thereby simultaneously assisting the movement of multiple door bodies 2.

[0055] Reference Figure 2 , Figure 6 The top of the gantry 1 is provided with a support frame 9, the arrangement direction of which is consistent with the axis direction of the drive screw 42, thereby forming a guide support structure that is adapted to the sliding trajectory of the adjustment frame 6. Each adjustment frame 6 is provided with a support block 91 on the side away from the door body 2. The support block 91 is slidably assembled in the support frame 9, and the sliding direction of the support block 91 is set along the length direction of the support frame 9.

[0056] By setting up support block 91 and support frame 9, a stable and reliable auxiliary support can be formed for adjustment frame 6, thereby enhancing the connection strength and structural rigidity between adjustment frame 6 and gantry 1. In addition, during the process of adjustment frame 6 driving push part 62 to lift gantry 2, support frame 9 can provide uniform force support points for adjustment frame 6 through support block 91, effectively dispersing the vertical load and horizontal thrust generated during lifting to the main body of gantry 1, thereby ensuring the structural stability of gantry 2 in the lifting state.

[0057] The implementation principle of this invention is as follows: When it is necessary to move the door body 2, the drive assembly 4 is activated and drives the two adjustment frames 6 of each group to move away from each other along the axis of the drive screw 42, thereby driving the support part 61 to move to the position where it abuts against the rotating wheel 511 on the mating part 51, forming a rolling support structure for the upper end of the door body 2; at the same time, the mating parts 51 are arranged in pairs symmetrically, providing a stable upper support during the sliding process of the door body 2, thereby effectively constraining the displacement trajectory of the door body 2 and ensuring the smoothness and accuracy of the sliding operation of the door body 2.

[0058] Once the door 2 has moved and is at a stop, the drive assembly 4 moves the two adjusting frames 6 of each group closer together. During this process, the rotating wheel 511 on the support part 61 and the mating part 51 gradually separates, releasing the sliding support constraint on the upper end of the door 2. Simultaneously, the movement of the adjusting frame 6 moves the pushing part 62 closer to the abutting part 52, so that the first inclined surface 621 and the second inclined surface 521 precisely fit and abut against each other. With the help of the inclined surface mating structure, the horizontal driving force is converted into a vertical upward lifting force, forming a stable lifting effect on the door 2. This lifting effect can effectively share the weight of the door 2, significantly reducing the contact pressure between the guide wheel 7 below the door 2 and the door frame 1, and reducing the wear, deformation and other damage problems caused by long-term pressure on the guide wheel 7, door frame 1 and other components.

[0059] By setting up the support part 61 and the pushing part 62, the door body 2 can achieve stable support under both moving and stationary working conditions. Relying on the stable support formed by the cooperation between the support part 61 and the rotating wheel 511 on the mating part 51, or the stable lifting effect formed by the cooperation between the pushing part 62 and the abutment part 52, the swaying amplitude of the door body 2 under external force disturbance can be greatly suppressed, ensuring the stability of the door body 2, reducing the phenomenon of damage to the structure of the door body 2, and at the same time significantly improving the sealing and closing effect of the door body 2 on the hangar, effectively blocking the influence of external environmental factors on the internal space of the hangar.
