Description

Technical Field

[0001] This application relates to the field of rail train technology, and in particular to an installation device and a rail train installation system. Background Technology

[0002] In high-speed trains, the main air supply module is the core component of the train's air supply system, responsible for the high-flow-rate air used in braking, air springs, doors, and whistles. The auxiliary air compressor is installed within the main air supply module, working in conjunction with the main air compressor to supplement the air supply and provide backup.

[0003] In related technologies, the main air supply module has a complex internal structure and limited space, which restricts the installation location of the auxiliary air compressor. The installation of the auxiliary air compressor must be carried out manually within a closed or semi-closed vehicle frame. The operator must move the auxiliary air compressor from the outside to a specific position inside the frame, and manually lift and adjust its position to align it with the frame connection holes of the main air supply module, and finally fix it with fasteners.

[0004] However, the installation methods in related technologies are limited by the confined space, and manual operation can easily cause problems such as deviation of the installation hole position and poor positioning accuracy. On the other hand, the installation environment of large components under the train usually has harsh conditions such as high temperature and dust, which further increases the difficulty and operational risks of manual installation of auxiliary air compressors, and ultimately affects the assembly efficiency of the train's air supply module. Summary of the Invention

[0005] This application provides an installation device and a railcar installation system to solve the problem that traditional technologies rely on manual operation, which affects the assembly efficiency of the air supply module for high-speed trains.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] The first aspect of this application provides an installation device suitable for a railcar installation system, comprising:

[0008] The support platform is configured to support the component to be installed, and at least one limiting element is provided at the edge of the support platform;

[0009] The equipment body includes a conveying mechanism that reciprocates along a first direction. The conveying mechanism includes a transmission component that reciprocates along the first direction. The transmission component is connected to a support platform. When the transmission component moves along the first direction, it transports the support platform from an initial position to an installation position.

[0010] A drive mechanism is mounted on the equipment body and is connected to the transmission assembly for driving the transmission assembly to reciprocate along a first direction, so that the position of the support platform along the first direction is adjustable.

[0011] The control unit communicates with the drive mechanism to move the transmission components, thereby driving the component to be installed.

[0012] In one possible implementation, the equipment body also includes a support and a lifting mechanism. The support is connected to the conveying mechanism, the lifting mechanism is fixed on the support, and the support platform is connected to the lifting mechanism through the support. The lifting mechanism moves vertically relative to the conveying mechanism so that the vertical position of the support platform is adjustable.

[0013] In one possible implementation, the system also includes a tray connected to a support, the tray connected to and located at the bottom of a support platform, and an adjustment mechanism between the tray and the support platform to make the position of the support platform relative to the tray adjustable along the plane of the tray.

[0014] In one possible implementation, the conveying mechanism further includes a first guide mechanism, and a second guide mechanism adapted to the first guide mechanism is provided at the bottom of the support, with the first guide mechanism and the second guide mechanism slidingly engaged.

[0015] In one possible implementation, the first guide mechanism is one of a slide rail or a slide groove, and the second guide mechanism is the other of a slide rail or a slide groove.

[0016] In one possible implementation, the transmission assembly is a gear and a rack, and the transmission assembly is connected to the second guide mechanism. When the transmission assembly moves in the first direction, it drives the second guide mechanism to slide within the first guide mechanism, thereby making the position of the support platform adjustable in the first direction.

[0017] In one possible implementation, the adjustment mechanism includes a drive motor and an adjustment member, the drive motor being driven to move the adjustment member, thereby causing relative movement between the tray and the support platform.

[0018] In one possible implementation, the adjusting element is a swivel ball, which is rotatably connected to the tray.

[0019] When the drive motor drives the omnidirectional ball to rotate, it causes the support platform to move relative to the tray, thereby causing the part to be installed to move.

[0020] In one possible implementation, the control unit includes a first controller, a second controller, and a third controller;

[0021] The first controller is communicatively connected to the conveying mechanism. The first controller is used to send motion commands to the conveying mechanism so that the transmission component reciprocates along the first direction.

[0022] The second controller is connected to the lifting mechanism and is used to send motion commands to the lifting mechanism so that the lifting mechanism can reciprocate vertically.

[0023] The third controller is connected to the adjustment mechanism and is used to send motion commands to the adjustment mechanism so that the adjustment component moves in a preset direction.

[0024] The installation equipment provided in this application embodiment, by setting a support platform for carrying the part to be installed, and setting at least one limiting member at the edge of the support platform, and by driving the support platform connected to it to reciprocate between the initial position and the installation position in the first direction by the conveying mechanism on the equipment body, and by using the drive mechanism and control unit to drive and control the movement of the transmission components, enables the part to be installed to achieve stable bearing, controlled conveying and adjustable position along the first direction during the installation process, thereby improving the alignment accuracy, assembly efficiency and installation consistency of the part to be installed in the limited installation space of the rail train, and reducing the operational risks caused by manual handling and adjustment, thus solving the problem of relying on manual operation and affecting the assembly efficiency of the air supply module of the EMU.

[0025] A second aspect of this application provides a railcar installation system, including the installation equipment described above.

Detailed Implementation

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0038] First, let me explain the terms used in this application:

[0039] First direction: refers to the transport direction of the conveying mechanism;

[0040] Component to be installed: In this embodiment, the component to be installed is an auxiliary air compressor, but the component to be installed is not limited to an auxiliary air compressor. This embodiment uses an auxiliary air compressor as an example for illustration.

[0041] In the field of railcar assembly technology, the installation of auxiliary air compressors within the main air supply module is a typical scenario for assembling components in confined spaces. The main air supply module is usually integrated into the vehicle underframe or the corresponding equipment installation area. Its internal layout is compact, and in addition to the auxiliary air compressor, it may also contain pipelines, frame beams, connection interfaces, and other functional components, thus significantly limiting installation access and operational margins. In the actual assembly process, the auxiliary air compressor to be installed needs to be transported to the vicinity of the main air supply module and further delivered into the designated installation area within the frame, where it is then docked and secured to its corresponding mounting position.

[0042] In related technologies, the installation of auxiliary air compressors often involves manual handling, lifting, and alignment, culminating in fastener fixation. Specifically, operators typically use basic handling tools to move the auxiliary air compressor near the main air supply module, then manually push, lift, or temporarily support the heavy component to gradually insert it into the frame. Upon approaching the installation position, multiple operators work together to adjust its position and correct its orientation, ensuring the mounting holes are aligned as closely as possible before fastening. However, in scenarios like the main air supply module of a railcar—characterized by confined space, numerous obstacles, and a complex working environment—the drawbacks are significant. Due to the large size and weight of the component to be installed, manual control within a limited range is difficult to maintain and smoothly guide its movement in the intended direction, leading to issues such as transport path deviation, discontinuous position adjustments, and even localized jamming. Near the installation position, accurate alignment of the mounting holes often relies on visual judgment and repeated attempts by the operator, which is not only time-consuming but also lacks repeatability, making it difficult to maintain consistent assembly quality across different shifts and personnel. Meanwhile, manual labor involves a heavy workload, and when handling heavy objects in confined spaces, there are risks such as collisions with surrounding structures, slippage of parts to be installed, and injuries from pinching or bumping, making it difficult to consistently guarantee operational safety. Especially when the installation cycle time requirement increases, traditional methods are more prone to amplifying assembly deviations due to personnel coordination errors and operator fatigue, thereby affecting overall assembly efficiency and quality stability.

[0043] To overcome the deficiencies in related technologies, this application provides an installation device applicable to railcar installation systems. This device uses a support platform as the bearing location for the component to be installed, and at least one limiting element is provided along the edge of the support platform to limit the component. Simultaneously, a conveying mechanism reciprocating along a first direction is provided on the device body. The conveying mechanism includes a transmission component connected to the support platform. With the cooperation of a drive mechanism and a control unit, the transmission component can move along the first direction, thereby transporting the support platform and the component to be installed from an initial position to the installation position, and enabling the position of the support platform along the first direction to be adjustable. This technical approach transforms the transportation process of the component to be installed from manually controlled to a controlled process, resulting in better stability, consistency, and safety in the constrained environment of the railcar's main air supply module, and improving assembly efficiency.

[0044] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0045] Please refer to Figure 1 An installation device provided in this application embodiment includes:

[0046] The support platform 200 is configured to support an auxiliary air compressor, and at least one limiting element 210 is provided at the edge of the support platform 200.

[0047] The equipment body 100 includes a conveying mechanism 110 that reciprocates along a first direction. The conveying mechanism 110 includes a transmission assembly 120 that reciprocates along the first direction. The transmission assembly 120 is connected to the support platform 200. When the transmission assembly 120 moves along the first direction, it transports the support platform 200 from the initial position to the installation position.

[0048] A drive mechanism 130 is disposed on the equipment body 100. The drive mechanism 130 is drivenly connected to the transmission assembly 120 and is used to drive the transmission assembly 120 to reciprocate along the first direction so that the position of the support platform 200 is adjustable along the first direction.

[0049] The control unit is communicatively connected to the drive mechanism 130 to move the transmission assembly 120, thereby driving the auxiliary air compressor.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, the support platform 200 is used to support the auxiliary air compressor and transport the auxiliary air compressor from the initial position to the installation position under the action of the conveying mechanism 110. At least one limiting member 210 is provided on the edge of the support platform 200 to constrain the auxiliary air compressor. The equipment body 100 is used to integrate the support, guide and drive installation base. The transmission component 120 in the conveying mechanism 110 is connected to the support platform 200 and reciprocates along the first direction under the action of the drive mechanism 130. The control unit is communicatively connected to the drive mechanism 130 to control the operation of the transmission component 120 and drive the auxiliary air compressor to move.

[0051] Specifically, such as Figure 1 As shown, the support platform 200 is a support component used to support auxiliary air compressors. Its function is to provide a stable placement surface for auxiliary air compressors and other auxiliary air compressors, and to maintain the relative stability of the component's posture during transportation, thereby facilitating subsequent docking and fixing. The support platform 200 is set within the working area of ​​the equipment body 100.

[0052] Understandably, in terms of spatial arrangement, the support platform 200 is typically located in the middle or upper part of the conveying path of the equipment body 100, so as to receive the auxiliary air compressor from the external receiving position and deliver it into the installation area in a predetermined direction. In this embodiment, the support platform 200 is rectangular. In other embodiments, the support platform 200 can be set as a frame-type support or a plate-type pallet 160. The rectangular platform surface facilitates stable support for the regularly shaped auxiliary air compressor, the frame-type support facilitates the formation of enclosures around the perimeter and also takes into account weight reduction, and the plate-type pallet 160 facilitates a compact structural arrangement in a limited space. The dimensions of the support platform 200 are usually adapted to the outer dimensions of the auxiliary air compressor. Its platform length and width can be larger than the outer dimensions of the auxiliary air compressor to reserve necessary margins for assembly errors, posture fine-tuning, and clamping space. Furthermore, the edge width of the support platform 200, the spacing of the support frame, and the load distribution can be matched and designed according to the mass and center of gravity of the auxiliary air compressor.

[0053] Specifically, such as Figure 1 As shown, the limiting member 210 is a constraint component located at the edge of the support platform 200. Its function is to restrict the edge of the auxiliary air compressor, preventing it from slipping, deflecting, or tipping during transport, start-up, shutdown, or attitude adjustment, thereby improving transport stability. The limiting member 210 is typically fixed to the edge of the support platform 200 by bolts, welding, or detachable snap-fit, allowing for position adjustment or replacement according to the shape of different auxiliary air compressors. The limiting member 210 can be located on one side, opposite sides, or multiple sides around the support platform 200 to accommodate different limiting requirements.

[0054] In this embodiment, the limiting member 210 is a baffle-type structure. In other embodiments, the limiting member 210 can be a fence-type structure or an adjustable pressure block type structure. The baffle-type structure is used to form a rigid boundary, the fence-type structure is used to form an enclosing constraint around the perimeter, and the adjustable pressure block type structure is convenient for adapting to auxiliary air compressors of different shapes and sizes.

[0055] Specifically, such as Figure 1 As shown, the equipment body 100 is a main frame that supports and integrates movement. Its function is to provide an installation foundation for the support platform 200, the conveying mechanism 110, the drive mechanism 130, and the control unit, and to ensure that the entire installation equipment has sufficient rigidity and guiding accuracy in a confined space through its own structure.

[0056] The conveying mechanism 110 is disposed within the equipment body 100 and is used to displace the support platform 200. Its function is to convert the driving force into reciprocating motion along a first direction via the transmission assembly 120, thereby stably transporting the support platform 200 and its auxiliary air compressor from the initial position to the installation position. The transmission assembly 120 in the conveying mechanism 110 is connected to the support platform 200 and moves along the first direction with the cooperation of the guide members. The first direction is as follows: Figure 1 The straight direction shown is aligned with the installation position to minimize path deviation and improve transport controllability in confined spaces. A force-transmitting connection can be formed between the transmission assembly 120 and the support platform 200 via a connecting seat, connecting plate, or coupling to ensure reliable power transmission.

[0057] The drive mechanism 130 is a power output unit installed on the device body 100, such as... Figure 3 As shown, in this embodiment, the drive mechanism 130 is located below the conveying mechanism 110. Its function is to provide continuous or intermittent driving force to the transmission assembly 120 so as to drive the transmission assembly 120 to reciprocate along the first direction and make the position of the support platform 200 adjustable.

[0058] In this embodiment, the drive mechanism 130 uses a servo motor, which facilitates closed-loop position control. In other embodiments, the drive mechanism 130 may be a stepper motor, a geared motor, or a hydraulic drive unit.

[0059] The control unit is a control device used to issue motion commands and coordinate the action of the drive mechanism 130. Its function is to control the start, stop, direction and speed of the drive mechanism 130 according to the preset program, manual input or external operation signal, so as to achieve precise positioning of the support platform 200 along the first direction.

[0060] In some implementation methods, please refer to Figure 1 , Figure 4 The equipment body 100 also includes a support 140 and a lifting mechanism 150. The support 140 is connected to the conveying mechanism 110, and the lifting mechanism 150 is fixed on the support 140. The support platform 200 is connected to the lifting mechanism 150 through the support 140. The lifting mechanism 150 moves vertically relative to the conveying mechanism 110 so that the vertical position of the support platform 200 is adjustable.

[0061] Specifically, such as Figure 1 , Figure 4As shown, the bracket 140 is a frame component used to support and connect the conveying mechanism 110 and the lifting mechanism 150. Connecting the conveying mechanism 110 and the lifting mechanism 150, its function is to provide structural support and transfer loads. The bracket 140 is installed within the equipment body 100 and forms a mounting base with the conveying mechanism 110. It also serves as a fixed platform for the lifting mechanism 150 to ensure structural stability and geometric accuracy throughout the conveying and lifting process. The bracket 140 and the conveying mechanism 110 can be fixed by bolt connection, welding connection, or locating pin connection. Alternatively, mounting ears, connecting flanges, or guide seats can be provided according to the overall assembly requirements to form a reliable support interface with the conveying mechanism 110.

[0062] Specifically, such as Figure 1 As shown, the function of the lifting mechanism 150 is to drive the support platform 200 to move vertically relative to the conveying mechanism 110 to adapt to installation requirements at different heights.

[0063] The lifting mechanism 150 is fixed on the support 140. The lifting mechanism 150 and the support 140 are located above the conveying mechanism 110 and are fixed by bolts, welding, or positioning pins, so that the lifting mechanism 150 can achieve stable lifting and lowering with the support 140 as a foundation during operation. The lifting mechanism 150 and the bearing platform 200 can be connected by a connecting plate, slider seat, guide sleeve, or intermediate force transmission component to smoothly transmit the lifting motion to the bearing platform 200 and avoid skewing or swinging during the lifting process. The lifting mechanism 150 can be structurally designed as a hydraulic lifting unit, an electric push rod, a screw lifting pair, or a scissor lifting mechanism 150. The lifting stroke can range from tens of millimeters to hundreds of millimeters, which can be determined according to the target height of the auxiliary air compressor inside the main air supply module and the height difference between the installation position and the conveying reference plane. When it is necessary to expand the application range, a single-stage lifting can be replaced with a multi-stage telescopic lifting, or a cylinder or hydraulic cylinder can be used instead of an electric drive to adapt to different power sources and control methods.

[0064] like Figure 1 As shown, the lifting mechanism 150 is driven by a gear and rack. After the support platform 200 is connected to the lifting mechanism 150 through the bracket 140, it can complete the vertical fine adjustment through the lifting mechanism 150 on the basis of the displacement along the first direction completed by the conveying mechanism 110, so that the auxiliary air compressor can achieve height matching when it approaches the installation position, thereby improving the accessibility and accuracy of installation docking.

[0065] When the system is started, the control unit can pre-set the sequence of conveying and lifting according to the initial position and installation height of the auxiliary air compressor. The drive mechanism 130 first drives the transmission component 120 to run in the first direction, so that the support platform 200 moves to the vicinity of the main air supply module under the action of the conveying mechanism 110. After the auxiliary air compressor enters the frame or approaches the target installation area, the lifting mechanism 150 begins to adjust vertically relative to the conveying mechanism 110, thereby improving the overall assembly efficiency and operation safety.

[0066] For some possible implementations, please refer to Figure 4 It also includes a tray 160, which is connected to a support 140 and connected to a support platform 200 and located at the bottom of the support platform 200. An adjustment mechanism 170 is also provided between the tray 160 and the support platform 200 so that the position of the support platform 200 relative to the tray 160 is adjustable along the plane where the tray 160 is located.

[0067] like Figure 4 As shown in this application, the tray 160 is a planar support member disposed below the support platform 200 and used to support the support platform 200. Its function is to provide a stable base support for the adjustment mechanism 170 and to provide a relatively fixed reference surface for the fine position adjustment of the support platform 200 in the plane.

[0068] Specifically, the tray 160 is connected to the support 140, typically by bolts, welding, or a detachable mounting base. The connection between the tray 160 and the support platform 200 serves to confine the support platform 200 within a predetermined area above the tray 160 and reliably transmit the displacement applied by the adjustment mechanism 170 to the auxiliary air compressor.

[0069] The adjustment mechanism 170 is a mechanical adjustment mechanism arranged between the pallet 160 and the support platform 200, used to drive the support platform 200 to produce planar displacement relative to the pallet 160. Its function is to make fine adjustments to the support platform 200 in the horizontal plane, so that the support platform 200 can complete translation, deflection or compound posture adjustment in the plane of the pallet 160, thereby improving the alignment accuracy between the auxiliary air compressor and the target mounting hole.

[0070] Understandably, the pallet 160 can be a flat pallet 160, a framed pallet 160, or a reinforced pallet 160, and its material can be steel plate, aluminum alloy plate, or composite material plate. The surface of the pallet 160 can also be equipped with a wear-resistant coating, anti-slip texture, or rolling contact surface according to friction conditions, so as to maintain sufficient structural strength and movement stability when bearing heavy auxiliary air compressors. Its planar dimensions are usually slightly larger than the bottom dimensions of the support platform 200, so as to leave adjustment and installation space at the edges of the pallet 160.

[0071] When the system starts, the pallet 160 first forms a stable bottom support platform through its connection with the bracket 140. The support platform 200 is then supported above the pallet 160 by the adjustment mechanism 170 provided on the pallet 160. In the initial loading state, the auxiliary air compressor is placed on the support platform 200 and its edge position is constrained by the limiting member 210 to prevent slippage during conveying and adjustment. As the conveying mechanism 110 sends the support platform 200 into the predetermined working area, the operator or control unit further drives the adjustment mechanism 170 to move, causing the support platform 200 to make slight displacements within the plane of the pallet 160, thereby gradually bringing the auxiliary air compressor closer to the center line of the hole or the docking reference surface of the target installation position. Since the pallet 160 and the bracket 140 provide stable support, and the relative position between the support platform 200 and the pallet 160 can be precisely corrected by the adjustment mechanism 170, the support platform 200 can still achieve small stroke and high-precision attitude correction after completing a large-scale conveying.

[0072] For some possible implementations, please refer to Figure 2 , Figure 3 The conveying mechanism 110 also includes a first guide mechanism 111, and the bottom of the bracket 140 is provided with a second guide mechanism 141 adapted to the first guide mechanism 111. The first guide mechanism 111 and the second guide mechanism 141 are slidably engaged.

[0073] The first guide mechanism 111 is a guide component used to limit and guide the movement trajectory of the conveying mechanism 110. Its function is to constrain the direction of the support platform 200 and its connected transmission assembly 120, so that the support platform 200 can achieve smooth and linear reciprocating movement in the first direction, thereby avoiding lateral sway, posture deviation or local jamming in the confined installation space such as the main air supply module of the railcar. The second guide mechanism 141 is set at the bottom of the bracket 140 and is structurally compatible with the first guide mechanism 111. The two together form a linear guide pair, thereby improving the guiding accuracy and repeatability of the conveying mechanism 110.

[0074] The first guide mechanism 111 and the second guide mechanism 141 are usually arranged on the main load-bearing path of the equipment body 100. The first guide mechanism 111 can be fixed to the transmission assembly 120, the support platform 200, or the connecting frame rigidly connected to it. The second guide mechanism 141 is set at the corresponding position at the bottom of the bracket 140 by bolts, pressure plates, or welding, so that when the transmission assembly 120 moves along a predetermined straight trajectory under the action of the drive mechanism 130, the guide pair always maintains a stable meshing state.

[0075] For some possible implementations, please refer to Figure 2 , Figure 3The first guide mechanism 111 is one of the slide rail or the slide groove, and the second guide mechanism 141 is the other of the slide rail or the slide groove.

[0076] Specifically, such as Figure 1 As shown, the second guide mechanism 141 at the bottom of the bracket 140 is a slider, and the first guide mechanism 111 below the conveying mechanism 110 is a slide groove. Both the slide rail and the slide groove are arranged along the first direction. The first guide mechanism 111 and the second guide mechanism 141 constitute a linear guide pair for the relative movement between the support platform 200 and the bracket 140. The two achieve stable linear guidance of the support platform 200 relative to the bracket 140 in the first direction through sliding cooperation, so that the support platform 200 can move smoothly along a predetermined path when driven by the drive mechanism 130, and maintain alignment accuracy when approaching the installation position, thereby reducing the possibility of the auxiliary air compressor colliding or jamming with the surrounding structure in a confined space. The slide rail can be fixed to the frame of the conveying mechanism 110 by bolts, welding or embedding, and the slide groove can be integrally machined on the profile, plate or mounting base at the bottom of the bracket 140, or an independent cavity can be formed by additional guide seats to maintain stable engagement with the slide rail.

[0077] It is understood that in other embodiments, the first guide mechanism 111 may also adopt a roller guide, a crossed roller guide, or a linear bearing guide to meet the assembly requirements of different load levels and accuracy levels.

[0078] For example, the slide rail can be made of rectangular cross section, dovetail cross section or arc cross section to enhance the resistance to eccentric load and guiding rigidity, and the slide groove can be made of rectangular groove, dovetail groove or U-shaped groove.

[0079] When the system starts, the drive mechanism 130, under the control of the control unit, drives the transmission assembly 120 connected to the support platform 200 to begin moving in the first direction. The support platform 200, together with the auxiliary air compressor on it, synchronously enters the controlled conveying state under the joint constraints of the first guide mechanism 111 and the second guide mechanism 141. Since the first guide mechanism 111 is one of a slide rail or a slide groove, and the second guide mechanism 141 is the other of a slide rail or a slide groove, the sliding pair formed by the two can continuously limit the lateral displacement and angular deflection of the support platform 200, so that the support platform 200 maintains a relatively parallel relationship with the support 140 during long-stroke movement, avoiding swaying caused by uneven force or inertia.

[0080] For some possible implementations, please refer to Figure 1 , Figure 2The transmission assembly 120 is a gear and a rack. The transmission assembly 120 is connected to the second guide mechanism 141. When the transmission assembly 120 moves in the first direction, it drives the second guide mechanism 141 to slide in the first guide mechanism 111, thereby making the position of the support platform 200 adjustable in the first direction.

[0081] Specifically, such as Figure 1 As shown, the gear and rack constitute a meshing transmission assembly 120 that converts rotary motion into linear motion. The gear is the power input component, and the rack is the force output component. The two achieve stable force and displacement transmission through tooth surface meshing. The function of this transmission assembly 120 is to convert the rotary power output by the drive mechanism 130 into linear displacement of the support platform 200 in the first direction, and to constrain the motion trajectory with the cooperation of the first guide mechanism 111 and the second guide mechanism 141 to reduce swaying and deviation.

[0082] The rack is fixedly connected to or integrally formed with the second guide mechanism 141, so that when the rack is driven by the gear, it can synchronously drive the second guide mechanism 141 to slide along the first guide mechanism 111. The gear is driven and connected to the output shaft of the drive mechanism 130, and power transmission can be achieved through key connection, spline connection, expansion sleeve connection or coupling connection. When the gear rotates, the rack moves linearly along the first direction under the action of the gear, thereby driving the second guide mechanism 141 to slide in a restricted manner within the first guide mechanism 111, so that the position of the support platform 200 relative to the equipment body 100 along the first direction is adjustable.

[0083] It is understood that in other embodiments, the transmission assembly 120 may be a lead screw and nut assembly or a synchronous belt drive assembly 120. The lead screw and nut assembly is suitable for high-precision position control, while the synchronous belt drive assembly 120 is suitable for smooth and low-noise operation.

[0084] Based on the foregoing embodiments, please refer to some possible implementation methods. Figure 4 The adjustment mechanism 170 includes a drive motor and an adjustment component 171. The drive motor is connected to the adjustment component 171 to drive the adjustment component 171 to move, thereby causing relative movement between the tray 160 and the support platform 200.

[0085] Specifically, the drive motor is usually mounted on the mounting position of the adjustment mechanism 170 and connected to the adjustment component 171 through a coupling, gear set, pulley or direct shaft connection, so as to stably transmit the rotational motion output by the motor to the adjustment component 171.

[0086] Adjustment component 171 is a mechanical component that moves under the action of drive motor and changes the relative position of support platform 200. Its function is to convert the rotational output of drive motor into relative displacement between tray 160 and support platform 200, thereby realizing attitude correction and position compensation of auxiliary air compressor on support platform 200.

[0087] When the system starts, the drive motor outputs rotational torque under the command of the control unit, and transmits power to the adjusting component 171 through a coupling, gear set, pulley, or direct shaft connection. Driven by the motor, the adjusting component 171 generates preset motion patterns such as continuous rotation, eccentric oscillation, or spiral propulsion, further driving the relative displacement between the tray 160 and the support platform 200. Due to the adjustment gap and mating interface between the tray 160 and the support platform 200, the support platform 200 can complete position compensation within the plane of the tray 160, gradually bringing the center position, hole orientation, or edge posture of the auxiliary air compressor closer to the predetermined installation state. Thus, after the support platform 200 is first fed into the target area by the conveying mechanism 110, the adjusting mechanism 170 can precisely correct the auxiliary air compressor through small-stroke, high-precision planar fine-tuning, reducing the need for repeated manual probing and repositioning, thereby improving alignment efficiency and assembly consistency within confined spaces.

[0088] In some possible implementation methods, please refer to Figure 4 The adjusting component 171 is a swivel ball, which is rotatably connected to the tray 160. When the drive motor drives the swivel ball to rotate, it drives the support platform 200 to move relative to the tray 160, thereby driving the auxiliary air compressor to move.

[0089] Specifically, a omnidirectional ball is a wheel-type adjustment component that can roll and steer in multiple directions. It is used to form a controllable planar adjustment mechanism inside the tray 160, so that after the drive motor outputs power, the position of the support platform 200 relative to the tray 160 can be changed by the rolling and steering of the wheels. For example... Figure 4 As shown, the omnidirectional ball is rotatably connected within the tray 160. It is assembled into the bottom of the tray 160 or the mounting cavity inside the tray 160 via a pivot, bearing housing, fork, or mounting bracket, and is connected to a drive motor, thus generating rotational motion under the motor's torque. The omnidirectional ball can be configured as a single-wheel, double-wheel, or fork-equipped structure. A single-wheel structure is easier to arrange and has lower frictional resistance, a double-wheel structure improves load-bearing capacity and posture stability, and a fork-equipped structure facilitates wheel steering and positioning.

[0090] In one possible implementation, the control unit includes a first controller, a second controller, and a third controller;

[0091] The first controller is communicatively connected to the conveying mechanism 110. The first controller is used to send motion commands to the conveying mechanism 110 so that the transmission component 120 reciprocates along the first direction.

[0092] The second controller is communicatively connected to the lifting mechanism 150. The second controller is used to send motion commands to the lifting mechanism 150 so that the lifting mechanism 150 can reciprocate vertically.

[0093] The third controller is communicatively connected to the adjustment mechanism 170. The third controller is used to send motion commands to the adjustment mechanism 170 so that the adjustment component moves in a preset direction.

[0094] Specifically, the first, second, and third controllers can be understood as control units targeting different motion modules, used for independent or coordinated control of conveying, lifting, and adjusting actions. The first controller is a control component that outputs commands to the conveying mechanism 110, the second controller is a control component that outputs commands to the lifting mechanism 150, and the third controller is a control component that outputs commands to the adjusting mechanism 170. The function of this control structure is to hierarchically manage the fine-tuning actions of the platform 200 in the horizontal conveying direction, the vertical lifting direction, and the plane of the tray 160, enabling each motion mechanism to execute independently or in conjunction according to a predetermined sequence. This avoids interference between multiple motion axes and improves the positioning accuracy and controllability of the auxiliary air compressor in confined spaces.

[0095] This application uses a PLC main controller as its core, combined with servo drives, human-machine interaction, and distributed I / O modules, to achieve precise motion control, real-time status monitoring, and safety protection for each mechanism, ensuring stable and reliable system operation. The control unit includes manual and automatic modes. Manual mode is used for equipment debugging, point teaching, and fault reset. The movement of the conveyor mechanism 110, lifting mechanism 150, and adjusting mechanism 170 can be controlled via physical or virtual buttons on the teach pendant. It supports low-speed jogging (JOG) and incremental jogging (INC). Automatic programs are disabled in this mode, which is used for teaching process paths for new parts to achieve flexible changeover. Automatic mode is used for normal production operation. The equipment automatically completes flipping and positioning actions according to preset programs and points. Manual jogging is disabled in this mode (except for emergency stop and reset buttons) to ensure production safety.

[0096] Specifically, the first, second, and third controllers can be configured as PLC sub-modules, embedded microcontrollers, motion control cards, or industrial computing units, respectively. The controller housings can be metal shielded shells, modular control boxes, or integrated chassis structures to adapt to the electromagnetic environment and installation space requirements of the train assembly site. The first, second, and third controllers can exchange data via bus, serial port, Ethernet, or wireless communication, or they can be connected to their respective actuators via independent signal lines, thus forming centralized control, distributed control, or hybrid control schemes. The controllers are typically equipped with communication interfaces, drive interfaces, and status feedback interfaces, capable of receiving control signals from the host computer, operation panel, or manual input, and performing closed-loop adjustment of each motion module based on feedback signals. Their installation locations can be centrally located within the control cabinet of the equipment body 100, or distributed near the conveying mechanism 110, lifting mechanism 150, or adjusting mechanism 170 to shorten wiring distances and improve anti-interference capabilities.

[0097] Furthermore, during actual control, after receiving the start signal, the first controller sends a motion command to the conveying mechanism 110 to drive the transmission component 120 to reciprocate along the first direction, thereby moving the support platform 200 together with the auxiliary air compressor on it along the predetermined conveying path to near the installation position; when it is necessary to adjust the height of the support platform 200, the second controller sends a lifting command to the lifting mechanism 150, and the lifting mechanism 150 reciprocates vertically to change the vertical position of the support platform 200 so that the auxiliary air compressor can match the height of the installation interface; when it is necessary to perform precise alignment in the plane, the third controller sends an adjustment command to the adjustment mechanism 170, and the adjustment component moves along the preset direction to make the support platform 200 undergo a small stroke displacement relative to the tray 160 to correct the planar position deviation of the mounting hole or connection reference. Since the three controllers correspond to different directions of motion, the auxiliary air compressor can gradually approach the target installation state in the process of conveying, lifting and fine-tuning according to the rhythm sequence of coarse positioning followed by fine positioning. This reduces the number of times manual handling and trial alignment are required, reduces the possibility of heavy objects swaying, jamming or colliding in narrow spaces, and makes the installation process more stable and reliable.

[0098] Furthermore, the control unit is equipped with a protection mechanism. Normally closed contacts are connected in series in the safety circuit. Pressing the emergency stop button directly cuts off the power supply to all servo drives and the main contactor via hardware, causing all motion mechanisms to stop instantly. After fault handling and resetting the emergency stop button, each motion mechanism must first be homed before the system can be restarted. Hardware limit switches are installed at both ends of each motion mechanism. Once a limit switch is triggered, the corresponding motion mechanism will be immediately stopped via hardware control. Simultaneously, software limit protection is set within the PLC program, forming a dual hardware and software limit protection mechanism. When PLC bus communication is interrupted, the PLC will immediately trigger the safety stop control logic, stopping all motion mechanisms and outputting a fault alarm signal. Simultaneously, the servo drives synchronously execute a power supply cut-off operation, effectively preventing equipment damage and safety accidents caused by communication failure.
