Description

Technical Field

[0001] This application relates to high-speed train maintenance technology, and more particularly to a high-speed train windshield wiper maintenance platform. Background Technology

[0002] High-speed trains are a type of train in the high-speed rail transportation system, characterized by high speed and operational efficiency. During routine maintenance, maintenance personnel need to inspect the windshield wipers, replace blades, and adjust the wiper angle and working effect to ensure proper operation and effective cleaning. This guarantees the driver has good visibility in various weather conditions, ensuring passenger safety and comfort.

[0003] A high-speed train windshield wiper maintenance platform is a workbench or device specifically designed for the inspection and maintenance of high-speed train windshield wipers. The platform includes a lifting device and a working platform.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0048] Please see Figure 1 and Figure 2 The high-speed train windshield wiper maintenance platform provided in this embodiment includes a movable seat 100, a work platform 200, a lifting assembly, a support assembly 400, and a drive assembly.

[0049] The worktable 200 is located on the upper side of the movable seat 100, and the bottom of the movable seat 100 is provided with casters 110. The lifting assembly includes a lifting component 300, which is movably mounted on the movable seat 100, and the worktable 200 is located on top of the lifting component 300.

[0050] The movable base 100 provides a stable mounting reference for the lifting assembly and the support assembly 400. Its rigid structure can withstand the total load of the work platform 200, personnel, and tools, and transfer the load to the ground. The movable base 100 achieves short-distance displacement of the platform through the casters 110 at the bottom. Before operation, the position can be locked by braking the casters 110 themselves.

[0051] The work platform 200 is a planar structure that supports maintenance personnel and tools. Its height is changed by the lifting assembly, allowing maintenance personnel to reach a maintenance height that matches the windshield wipers of the train. The lifting component 300 can extend, retract, or slide in a direction perpendicular to the ground, converting the power of the drive component 510 into the lifting displacement of the work platform 200. Different maintenance heights can be adapted by adjusting the lifting stroke.

[0052] Please see Figure 3The support assembly 400 includes a support member 410, which is vertically and flexibly disposed on the bottom side of the movable seat 100.

[0053] The support component 400 expands the support area of ​​the entire platform through the rigid contact between the support member 410 and the ground, thereby dispersing the load borne by the moving seat 100, reducing the ground pressure per unit area, and suppressing platform sway. The support member 410 can be raised and lowered from the bottom side of the moving seat 100, maintaining a distance from the ground in the initial state, and descending and contacting the ground in the working state to form an auxiliary support structure.

[0054] The drive assembly includes a drive member 510 and a threaded column 520. The drive member 510 is connected to the threaded column 520 in a transmission manner. The threaded column 520 is also connected to the lifting member 300 and the support member 410 in a transmission manner. The drive member 510 can drive the threaded column 520 to rotate, so that the lifting member 300 rises and drives the work platform 200 to rise, and so that the support member 410 falls and touches the ground.

[0055] The drive unit 510 outputs power to drive the threaded column 520 to rotate. The threaded column 520 forms a linkage relationship with the lifting component 300 and the support component 410 through threaded transmission. Specifically, when the drive unit 510 drives the threaded column 520 to rotate forward, the threaded engagement between the threaded column 520 and the lifting component 300 causes the lifting component 300 to move upward, thereby driving the work platform 200 to rise. At the same time, the reverse threaded engagement between the threaded column 520 and the support component 410 causes the support component 410 to move downward until it touches the ground. When rotating in the reverse direction, the work platform 200 descends and the support component 410 is lifted off the ground. Therefore, in this embodiment, the lifting and supporting actions are synchronously controlled through the same power source, avoiding safety hazards caused by misalignment of action timing.

[0056] Therefore, this implementation uses the linkage between the support component 400 and the lifting component to simultaneously lower the support component 410 and bring it to the ground during the lifting of the work platform 200, thereby expanding the support area of ​​the entire platform, dispersing the load borne by the moving seat 100, improving the stability of the entire platform, and solving the problem of insufficient stability when supported solely by the casters 110.

[0057] Since the lifting stroke of the support member 410 is generally shorter than that of the lifting member 300, in order to accommodate the forming distance between the two, in some optional embodiments, the threaded column 520 has a first threaded section 521 and a second threaded section 522. The first threaded section 521 is drivenly connected to the lifting member 300, and the second threaded section 522 is drivenly connected to the support member 410, and the pitch of the first threaded section 521 is greater than the pitch of the second threaded section 522.

[0058] In threaded drives, the linear travel of a component is positively correlated with the thread pitch and the number of rotations. Since the support member 410 only needs a short descent to the ground, while the lifting member 300 needs to raise the worktable 200 to a higher wiper maintenance height, the first thread section 521 uses a large pitch, and the second thread section 522 uses a small pitch. This ensures that, for the same number of rotations, the travel of the lifting member 300 automatically adapts to its required large distance, while the travel of the support member 410 synchronously adapts to its required small distance.

[0059] The two threads of the threaded column 520 are designed as a single piece, ensuring that the rotational power output by the drive component 510 is transmitted through the same transmission path. This not only ensures the synchronization of lifting and supporting actions, but also naturally distributes the stroke through the difference in thread pitch, which helps to simplify the overall structural layout of the platform and make the overall size of the platform more compact.

[0060] In some alternative embodiments, please continue to refer to Figure 1 and Figure 2 The lifting component 300 includes a scissor-type support frame 310 and a first connecting rod 320.

[0061] The scissor support frame 310 has a first support leg 311 and a second support leg 312 at its bottom. The first support leg 311 is rotatably connected to the movable seat 100, and the worktable 200 is located on the top of the scissor support frame 310.

[0062] The scissor lift support frame 310 is a cross-hinged rod structure with a first support leg 311 and a second support leg 312 symmetrically arranged at its bottom. When the distance between the first support leg 311 and the second support leg 312 decreases, the cross angle of the scissor lift increases, and the top height rises; when the distance increases, the cross angle decreases, and the top height decreases. This structure distributes the force through multiple sets of cross rods, allowing the load of the workbench 200 to be evenly transferred to the bottom support legs. The first support leg 311 and the movable seat 100 can be rotatably connected by a pin, forming a fixed hinge fulcrum, which serves as the rotation center when the scissor lift is unfolded or folded.

[0063] The second leg 312 is sleeved on the first connecting rod 320, and the second leg 312 is rotatably connected to the first connecting rod 320. The first connecting rod 320 includes a first connecting part 321 and a second connecting part 322. The first connecting part 321 is sleeved on the first threaded section 521 and threadedly engaged with the first threaded section 521. The second connecting part 322 is slidably connected to the movable seat 100. When the threaded column 520 rotates, the first connecting rod 320 drives the second leg 312 to slide relative to the movable seat 100 through the first connecting part 321, so that the second leg 312 moves closer to or away from the sliding first leg 311.

[0064] The second support leg 312 serves as a movable fulcrum and can be sleeved onto the middle of the first connecting rod 320. It can also rotate around the axis of the connecting rod, ensuring that the second support leg 312 can adapt to the angle changes of the scissor lift while sliding with the connecting rod.

[0065] The outer surface of the first connecting part 321 is machined with an internal thread that matches the first threaded section 521. Threaded transmission is achieved through a sleeve engagement. When the threaded column 520 rotates, the first connecting part 321 moves linearly along the axial direction of the threaded column 520. The second connecting part 322 slides with a groove or slide rail on the movable seat 100, restricting the movement trajectory of the first connecting rod 320 to a straight line and preventing radial offset due to threaded transmission.

[0066] The first connecting rod 320 converts the rotational motion of the threaded column 520 into the linear sliding motion of the second support leg 312. Specifically, the rotation of the threaded column 520 causes the first connecting part 321 to slide along the connecting rod as a whole, which in turn causes the second support leg 312 to move closer to or further away from the first support leg 311 along the movable seat 100, thereby changing the crossing angle of the scissor lift and controlling the rise or fall of the worktable 200.

[0067] In this embodiment, the scissor-type support frame 310 converts the vertical load of the workbench 200 into the axial force of the rod system through multiple sets of cross rods of the scissor structure, thereby avoiding excessive stress at a single point and improving the overall operational stability of the maintenance platform.

[0068] In some alternative embodiments, please refer to Figure 1 and Figure 2 The movable seat 100 is provided with a first sliding groove 120 along the length direction of the threaded post 520, and the second connecting part 322 is provided in the first sliding groove 120, and the second connecting part 322 slides with the first sliding groove 120, thereby enabling the first connecting rod 320 to slide with the movable seat 100.

[0069] The first sliding groove 120 provides a unique motion trajectory constraint for the second connecting part 322, limiting the displacement of the first connecting rod 320 perpendicular to the sliding direction, such as jumping up and down or swinging left and right, so that the axial force generated by the threaded transmission is completely converted into the sliding power of the second support leg 312, avoiding the dispersion and loss of force. For example, the first sliding groove 120 can be formed on the upper surface or side wall of the movable seat 100 along the length direction of the threaded post 520.

[0070] The second connecting part 322 is disposed within the first sliding groove 120. It can be a protrusion structure that snaps into the first sliding groove 120, or it can be located within the rod-shaped structure. When the first connecting rod 320 moves axially under the drive of the threaded column 520, the second connecting part 322 slides along the length of the groove. The groove wall restricts the radial degree of freedom of the connecting part through surface contact, ensuring that the first connecting rod 320 always translates along the axial direction of the threaded column 520.

[0071] In some alternative embodiments, please refer to Figure 1 and Figure 2 The movable seat 100 includes a first limiting part 130 and a second limiting part 140. The first limiting part 130 is located on one side of the sliding direction of the first connecting rod 320, and the second limiting part 140 is located on the other side of the sliding direction of the first connecting rod 320.

[0072] The movable seat 100 forms a bidirectional mechanical limit on the sliding stroke of the first connecting rod 320 by setting the first limiting part 130 and the second limiting part 140. This limits the extreme position of the first connecting rod 320 by physically blocking it, preventing structural damage or overtravel caused by excessive sliding of the first connecting rod 320.

[0073] The distance between the first limiting part 130 and the second limiting part 140 matches the designed sliding stroke of the first connecting rod 320, ensuring that the first connecting rod 320 is within a safe range of motion throughout its entire stroke.

[0074] In some alternative embodiments, please refer to Figure 3 The support assembly 400 also includes a rotating column 420, a worm gear 430, a fixed cylinder 440, and a threaded sleeve 450.

[0075] The rotating column 420 passes through the bottom wall of the movable seat 100 and is rotatably mounted relative to the movable seat 100. The worm gear 430 is located on the upper side of the bottom wall of the movable seat 100, and is fixedly sleeved on the rotating column 420, and meshes with the second threaded section 522.

[0076] The rotating column 420 transmits the rotational motion of the worm gear 430 to the lower threaded section, achieving vertical power transmission. The rotating column 420 can be a cylindrical rod, vertically inserted into the bottom wall of the movable seat 100. It can form a rotational fit with the bottom wall via bearings. The upper part of the rotating column 420 is fixedly connected to the worm gear 430, and the lower outer surface can be machined with trapezoidal external threads, serving as the transmission basis for the threaded sleeve 450. The worm gear 430 engages with the second threaded section 522, and as the threaded column 520 rotates, it rotates around its own axis, thereby driving the rotating column 420 to rotate.

[0077] The fixed cylinder 440 is located on the lower side of the bottom wall of the movable seat 100. The top end of the fixed cylinder 440 is fixedly connected to the bottom wall of the movable seat 100, and the rotating column 420 is located inside the fixed cylinder 440. The lower part of the rotating column 420 is provided with external threads, and the threaded sleeve 450 is sleeved on the rotating column 420 and fixedly connected to the support member 410. The threaded sleeve 450 also includes a third connecting part 451. The fixed cylinder 440 is provided with a third sliding groove 441 along the length direction of the rotating column 420, and the third connecting part 451 is provided in the third sliding groove 441 so that the threaded sleeve 450 slides in the fixed cylinder 440.

[0078] The fixed cylinder 440 is a cylindrical or rectangular tube with an open bottom. Its top end can be welded or bolted to the bottom wall of the movable seat 100. The fixed cylinder 440 is located outside the rotating column 420, forming radial protection for the rotating column 420 and isolating it from the working space. Since the third connecting part 451 of the threaded sleeve 450 is slidably connected in the third sliding groove 441, the threaded sleeve 450 can convert the rotational motion of the rotating column 420 into its own linear motion through threaded engagement, thereby driving the support member 410 to move to the position abutting the ground.

[0079] When the driving component 510 drives the threaded column 520 to rotate, the second threaded section 522 drives the worm gear 430 to rotate, causing the worm gear 430 to drive the rotating column 420 to rotate synchronously. Since the lower external thread of the rotating column 420 is engaged with the internal thread of the threaded sleeve 450, the threaded sleeve 450 descends along the fixed cylinder 440 under the guidance of the third sliding groove 441, thereby pushing the support member 410 to abut against the ground. When the threaded column 520 rotates in the opposite direction, the threaded sleeve 450 rises, causing the support member 410 to lift off the ground.

[0080] In some embodiments, the support assembly 400 is provided in two sets, and the two sets of support assemblies 400 are symmetrically arranged on both sides of the threaded post 520. One set is located on one radial side of the threaded post 520, and the other set is located on the other radial side of the threaded post 520, thereby further improving the overall stability of the maintenance platform.

[0081] In some optional embodiments, the bottom end of the support member 410 is provided with an anti-slip part to increase the friction between the support member 410 and the ground, further enhance the anti-slip capability, and thus further improve the stability of the maintenance platform.

[0082] The anti-slip part can be made of highly elastic and wear-resistant materials, such as polyurethane rubber or nitrile rubber, and can be integrally molded with the bottom of the support component 410, or detachably connected by bolts for easy replacement after wear. The anti-slip part can also be processed with anti-slip textures, such as striped ridges, annular grooves, serrated protrusions, etc., to enhance grip on the ground.

[0083] In some alternative embodiments, the movable seat 100 further includes a fixing block 150, which is located at the end of the threaded post 520 away from the drive member 510, and the threaded post 520 is rotatably connected to the fixing block 150.

[0084] The movable seat 100 forms a rigid support for the end of the threaded column 520 away from the driving component 510 by adding a fixed block 150, thereby achieving positioning constraints on both ends of the threaded column 520, eliminating the deflection deformation of the suspended part of the threaded column 520, and ensuring the accuracy of thread transmission and structural stability.

[0085] For example, the fixing block 150 is provided with a shoulder retaining ring on one side near the middle of the threaded post 520, and the threaded post 520 is provided with an annular groove. The shoulder retaining ring is engaged with the annular groove to restrict the axial movement of the threaded post 520. At the same time, the outer ring of the bearing is pressed and fixed by the end cover to prevent the bearing from loosening due to vibration during operation.

[0086] In some alternative embodiments, please refer to Figure 4 The workbench 200 includes the workbench body 210, the guardrail 220, and the toolbox 230.

[0087] The workbench body 210 is connected to the top of the scissor lift support frame 310. A guardrail 220 surrounds the workbench body 210, and a railing 221 is provided at the top of the guardrail 220. The guardrail 220 and the railing 221 are connected by a connecting rod. The toolbox 230 is slidably connected to the railing 221 via a sliding sleeve 231.

[0088] The guardrail 220 forms a continuous physical barrier around the work platform 210, which can effectively prevent personnel from leaning out of the edge of the work platform 200 and prevent maintenance personnel from falling from a height.

[0089] Toolbox 230 can be used to store wrenches, wipers, and other tools needed for windshield wiper maintenance in a categorized manner, making it convenient for maintenance personnel to store and retrieve tools. Through the cooperation of sliding sleeve 231 and surrounding rod 221, toolbox 230 can move along the length of surrounding rod 221, allowing tools to move with the user. This shortens the path for maintenance personnel to retrieve tools, thereby improving maintenance efficiency and alleviating the time-consuming problem of frequent tool relocation caused by fixed tool placement.

[0090] In some optional embodiments, the top of the scissor support frame 310 includes a first support leg 313 and a second support leg 314, with the first support leg 313 rotatably connected to the workbench body 210. The lifting component 300 also includes a second connecting rod 330, and the workbench body 210 is provided with a second sliding groove 211 along the length direction of the threaded post 520, with the second connecting rod 330 disposed within the second sliding groove 211.

[0091] The second support leg 314 is rotatably connected to the second connecting rod 330, and the second connecting rod 330 is slidably engaged with the second sliding groove 211 so that the second support leg 314 moves closer to or further away from the first support leg 313.

[0092] The first support leg 313 serves as the upper rotation center when the scissor lift is unfolded or folded. The first support leg 313 is the fixed hinge point at the top of the scissor lift support frame 310. It can be rotatably connected to the bottom of the workbench body 210 through a pin, and together with the first support leg 311 at the bottom, it serves as a fulcrum.

[0093] The second support leg 314 converts the angular displacement of the scissor lift into the linear lifting motion of the worktable 200, forming a kinematic pair with the second support leg 312 at the bottom. The second support leg 314 is the movable fulcrum at the top of the scissor lift support 310, and can be rotatably connected to the second connecting rod 330 through a bushing, while sliding along the second sliding groove 211 of the worktable 200 with the second connecting rod 330.

[0094] Thus, the scissor lift support 310, through the first support leg 313 and the second support leg 314, constrains its spatial movement within a preset plane, keeping the work platform 200 horizontal. When the bottom first connecting rod 320 drives the second support leg 312 to slide, the top second connecting rod 330 simultaneously slides along the second sliding groove 211, keeping the work platform horizontal and enabling lifting and lowering.
