Description

Technical Field

[0001] This invention relates to the field of module lifting technology, and in particular to a multi-disciplinary module lifting device for subway electromechanical systems. Background Technology

[0002] In the installation of subway electromechanical systems, the lifting and positioning of electromechanical modules are common operational requirements. Traditional lifting devices typically employ a single hydraulic or mechanical lifting method, which suffers from limited adjustment range, insufficient stability, and complex operation. This is particularly problematic in installation scenarios involving multiple electromechanical modules from different disciplines, where the weight, size, and lifting height vary significantly. Traditional devices struggle to achieve rapid and precise adjustment and lifting, leading to low work efficiency and even safety hazards. Currently, most lifting devices on the market are designed with a fixed height, failing to flexibly adapt to different working conditions. While some height-adjustable devices achieve lifting functions through simple mechanical structures, they lack a stable self-locking mechanism, making them prone to slippage or vibration during lifting, affecting operational accuracy. Furthermore, traditional devices often use a single drive system, making it difficult to simultaneously meet the dual requirements of lifting height adjustment and load stability, thus limiting the equipment's applicability. Therefore, there is an urgent need for a comprehensive lifting device that can flexibly adjust the lifting height, possesses a stable self-locking function, and is suitable for multiple electromechanical modules from different disciplines, in order to improve work efficiency and ensure operational safety. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a multi-professional module lifting device for subway electromechanical systems, comprising a main body mechanism for movement, the main body mechanism including a moving frame, and an adjustment mechanism for adjusting the lifting height of the electromechanical modules and a lifting mechanism for lifting the electromechanical modules. The adjustment mechanism includes a side fixing plate fixedly installed on the movable frame, a lifting frame slidably installed on the side fixing plate, and a docking gear rotatably installed on the lifting frame.

[0004] Furthermore, the main structure includes four movable wheels rotatably mounted below the movable frame, a sprocket rotatably mounted on the lifting frame, an inner slider slidably mounted inside the movable frame, the inner slider being fixedly connected to one end of a chain, and a lifting plate being fixedly mounted on the other end of the chain, with the chain meshing with the sprocket.

[0005] Furthermore, a drive gear is rotatably mounted on the lifting frame, the drive gear is fixedly mounted with the mating gear, and the drive gear meshes with a coaxial gear ring on the sprocket.

[0006] In use, the electromechanical module to be lifted is placed on the lifting plate, and the main body is moved to the designated working position by the moving wheels. The mating gear drives the drive gear to rotate, which drives the sprocket to rotate. The sprocket drives the chain to rotate, and the chain drives the lifting plate to rise and fall.

[0007] Furthermore, the adjustment mechanism also includes a bidirectional lead screw rotatably mounted on the side fixed plate, the bidirectional lead screw being provided with bidirectional external threads, a lower rotating rod rotatably mounted on the movable frame, an upper rotating rod rotatably mounted on the lower rotating rod, and the upper rotating rod being rotatably mounted with the lifting frame.

[0008] Furthermore, an internal threaded sleeve is rotatably mounted on the bidirectional lead screw, and an internal thread is provided inside the internal threaded sleeve. The internal threaded sleeve and the bidirectional external thread of the bidirectional lead screw form a threaded transmission. Side columns are fixedly mounted on both sides of the internal threaded sleeve, and a sliding groove is provided on the lower rotating rod, in which the side columns slide.

[0009] Furthermore, an adjusting motor is fixedly installed on the movable frame, and an external transmission wheel is rotatably installed on the movable frame. The adjusting motor drives the external transmission wheel to rotate through an output belt, and the external transmission wheel drives the bidirectional lead screw to rotate through a vertical transmission belt.

[0010] Since different electromechanical modules require different lifting heights, the height of the lifting frame needs to be adjusted to change the lifting height of the electromechanical modules. The adjusting motor starts the outer drive wheel to rotate through the output belt, which in turn drives the double-sided lead screw to rotate through the vertical drive belt. The double-sided lead screw drives the inner threaded sleeve to slide along the double-sided lead screw, thereby driving the lower rotating rod to rotate through the sliding of the side column in the slide groove, which in turn drives the upper rotating rod to rotate, thereby driving the lifting frame to rise. When the lifting frame rises, it will also drive the chain to rise at the same time, and the inner slider slides in the moving frame.

[0011] Furthermore, the lifting mechanism includes a lifting motor fixedly mounted on a movable frame, a motor gear fixedly mounted on the motor shaft of the lifting motor, a lifting wheel rotatably mounted on the movable frame, the lifting wheel meshing with the motor gear, a worm and a worm wheel rotatably mounted on the movable frame, the worm wheel meshing with the worm, and the lifting wheel driving the worm to rotate through a bottom transmission belt.

[0012] Furthermore, a lower driven rod is rotatably mounted on the movable frame, and an upper driven rod is rotatably mounted on the lower driven rod. The upper driven rod is rotatably mounted with the lifting frame. A lower transmission wheel is rotatably mounted on the lower driven rod. A worm gear drives the lower transmission wheel to rotate through a short transmission belt. A middle transmission wheel is rotatably mounted on the lower driven rod. The middle transmission wheel is rotatably mounted with the upper driven rod. A lower transmission belt is wound around the middle transmission wheel and the lower transmission wheel. An upper transmission wheel is rotatably mounted on the upper driven rod. An upper transmission belt is wound around the upper transmission wheel and the middle transmission wheel. A lower connecting gear is rotatably mounted on the lifting frame. A lifting transmission belt is wound around the lower connecting gear and the connecting gear. The lower connecting gear meshes with the upper transmission wheel.

[0013] When adjusting the lifting frame, the lifting frame drives the upper driven rod to rotate, which in turn drives the lower driven rod to rotate. The lower driven rod rotates relative to the moving frame. When the electromechanical module needs to be lifted, the lifting motor drives the motor gear to rotate, which in turn drives the lifting wheel to rotate. This drives the worm gear to rotate via the bottom transmission belt, which in turn drives the worm wheel to rotate. This drives the lower transmission wheel to rotate via the short transmission belt, which in turn drives the middle transmission wheel to rotate via the lower transmission belt. This drives the upper transmission wheel to rotate via the upper transmission belt, which in turn drives the lower docking gear to rotate. Finally, this drives the docking gear to rotate via the lifting transmission belt. The worm gear and worm wheel have a self-locking characteristic, which keeps the electromechanical module stable during the lifting process.

[0014] The advantages of this invention compared to the prior art are: 1. This invention achieves stepless height adjustment of the lifting frame through the precise fit of a bidirectional lead screw and an internal threaded sleeve, combined with a multi-link linkage mechanism. This design allows for flexible adjustment of the lifting range based on the weight, size, and installation requirements of different electromechanical modules, ensuring the device is suitable for various complex working conditions. Compared to traditional fixed lifting equipment, this device can adapt to installation requirements at different heights, significantly improving versatility, reducing the purchase cost of specialized equipment, and meeting the installation and maintenance requirements of multiple professional electromechanical modules.

[0015] 2. This invention employs a worm gear transmission mechanism, which utilizes its inherent self-locking characteristics to ensure that the electromechanical module can remain stably suspended even in the event of a sudden power outage or external interference during the lifting process. This effectively prevents the load from slipping or falling accidentally. At the same time, the meshing transmission method of gears and chains further enhances the rigidity and stability of the system, making the lifting process smoother, avoiding shaking or deviation, and improving operational safety and positioning accuracy.

[0016] 3. By optimizing the layout of the sprockets, gears, and transmission belts, this invention maintains a compact overall structure while ensuring strength, making it easy to move and operate in narrow or complex environments. The design of the moving wheels enhances the mobility of the device, allowing it to be easily transported to different work positions. In addition, the use of motor drive combined with mechanical linkage control reduces manual adjustment steps, making operation simpler, significantly improving work efficiency, and reducing labor intensity.

[0017] 4. This invention achieves linkage control between the height adjustment of the lifting frame and the lifting of the electromechanical module through the coordinated action of the transmission belt, gear set and linkage mechanism. The adjustment mechanism and the lifting mechanism cooperate with each other to automatically compensate for the chain length while adjusting the height, ensuring the smooth movement of the lifting plate, reducing manual intervention, improving the level of automation, and making the entire lifting process smoother and more efficient. It is suitable for batch operations or high-precision installation scenarios, and effectively improves the overall construction efficiency. Attached Figure Description

[0028] Example: Reference Figures 1 to 8A multi-functional electromechanical module lifting device for subways includes a main body mechanism for movement, the main body mechanism including a moving frame 101, and an adjustment mechanism for adjusting the lifting height of the electromechanical modules and a lifting mechanism for lifting the electromechanical modules. The adjustment mechanism includes a side fixing plate 212 fixedly installed on the movable frame 101, a lifting frame 201 slidably installed on the side fixing plate 212, and a docking gear 107 rotatably installed on the lifting frame 201.

[0029] like Figure 2 , Figure 3 As shown, the main mechanism includes four movable wheels 102 rotatably mounted below the movable frame 101, a sprocket 105 rotatably mounted on the lifting frame 201, an inner slider 108 slidably mounted inside the movable frame 101, the inner slider 108 being fixedly connected to one end of the chain 104, the other end of the chain 104 suspending the lifting plate 103, and the chain 104 meshing with the sprocket 105.

[0030] like Figure 2 , Figure 3 As shown, a drive gear 106 is rotatably mounted on the lifting frame 201. The drive gear 106 is coaxially fixedly mounted with the mating gear 107, and the drive gear 106 meshes with the coaxial gear ring on the sprocket 105.

[0031] In use, the electromechanical module to be lifted is placed on the lifting plate 103, and the main body is moved to the designated working position by the moving wheel 102. The docking gear 107 drives the drive gear 106 to rotate, which drives the sprocket 105 to rotate. The sprocket 105 drives the chain 104 to rotate, and the chain 104 drives the lifting plate 103 to rise and fall.

[0032] like Figures 4-6 As shown, the adjustment mechanism also includes a bidirectional lead screw 202 rotatably mounted on the side fixed plate 212. The bidirectional lead screw 202 is provided with bidirectional external threads. A lower rotating rod 204 is rotatably mounted on the moving frame 101.

[0033] like Figures 4-6 As shown, an internal threaded sleeve 206 is rotatably mounted on the bidirectional lead screw 202. The internal threaded sleeve 206 has an internal thread. The internal threaded sleeve 206 and the bidirectional external thread of the bidirectional lead screw 202 form a threaded transmission. Side columns 207 are fixedly mounted on both sides of the internal threaded sleeve 206. A sliding groove 205 is provided on the lower rotating rod 204. The side columns 207 can slide in the sliding groove 205.

[0034] like Figures 4-6As shown, an adjusting motor 208 is fixedly installed on the movable frame 101, and an outer drive wheel 210 is rotatably installed on the movable frame 101. The adjusting motor 208 drives the outer drive wheel 210 to rotate through the output belt 209, and the outer drive wheel 210 drives the bidirectional lead screw 202 to rotate through the vertical drive belt 211.

[0035] Since different electromechanical modules require different lifting heights, the height of the lifting frame 201 needs to be adjusted to change the lifting height of the electromechanical modules. The adjusting motor 208 starts the outer transmission wheel 210 to rotate through the output belt 209, and drives the bidirectional lead screw 202 to rotate through the vertical transmission belt 211. The bidirectional lead screw 202 drives the inner threaded sleeve 206 to slide along the bidirectional lead screw 202, thereby driving the lower rotating rod 204 to rotate through the sliding of the side column 207 in the slide groove 205, thereby driving the upper rotating rod 203 to rotate, thereby driving the lifting frame 201 to rise. When the lifting frame 201 rises, it will simultaneously drive the chain 104 to rise, and the inner slider 108 will slide in the moving frame 101.

[0036] like Figure 7 , Figure 8 As shown, the lifting mechanism includes a lifting motor 301 fixedly mounted on a movable frame 101. A motor gear 302 is fixedly mounted on the motor shaft of the lifting motor 301. A lifting wheel 303 is rotatably mounted on the movable frame 101 and meshes with the motor gear 302. A worm 305 and a worm wheel 306 are rotatably mounted on the movable frame 101 and mesh with the worm 305. The lifting wheel 303 drives the worm 305 to rotate through a bottom transmission belt 304.

[0037] like Figure 7 , Figure 8 As shown, a lower driven rod 309 is rotatably mounted on the movable frame 101, and an upper driven rod 310 is rotatably mounted on the lower driven rod 309. The upper driven rod 310 is rotatably mounted to the lifting frame 201. A lower transmission wheel 308 is rotatably mounted on the lower driven rod 309. A worm gear 306 drives the lower transmission wheel 308 to rotate via a short transmission belt 307. A middle transmission wheel 312 is rotatably mounted on the lower driven rod 309. The middle transmission wheel 312 rotates with the upper driven rod 310. The upper drive wheel 314 is rotatably mounted on the upper driven rod 310. The upper drive wheel 314 and the upper drive wheel 312 are wrapped with an upper drive belt 313. The lower connecting gear 315 is rotatably mounted on the lifting frame 201. The lower connecting gear 315 and the connecting gear 107 are wrapped with a lifting drive belt 316. The lower connecting gear 315 meshes with the upper drive wheel 314.

[0038] When adjusting the lifting frame 201, the lifting frame 201 drives the upper driven rod 310 to rotate, and the rotation of the upper driven rod 310 drives the lower driven rod 309 to rotate. The lower driven rod 309 rotates relative to the moving frame 101. When it is necessary to lift the electromechanical module, the lifting motor 301 drives the motor gear 302 to rotate, which drives the lifting wheel 303 to rotate. The bottom transmission belt 304 drives the worm 305 to rotate, which drives the worm wheel 306 to rotate. The short transmission belt 307 drives the lower transmission wheel 308 to rotate. The lower transmission belt 311 drives the middle transmission wheel 312 to rotate. The upper transmission belt 313 drives the upper transmission wheel 314 to rotate, which drives the lower docking gear 315 to rotate. The lifting transmission belt 316 drives the docking gear 107 to rotate. The worm 305 and the worm wheel 306 have a self-locking characteristic, which makes the electromechanical module remain stable during the lifting process.

[0039] The working principle of the metro electromechanical multi-professional module lifting device disclosed in this invention is as follows: In use, the electromechanical module to be lifted is placed on the lifting plate 103. The main body mechanism is moved to the designated working position by the moving wheel 102. The lifting motor 301 drives the motor gear 302 to rotate, which drives the lifting wheel 303 to rotate. The bottom transmission belt 304 drives the worm 305 to rotate, which drives the worm wheel 306 to rotate. The short transmission belt 307 drives the lower transmission wheel 308 to rotate. The lower transmission belt 311 drives the middle transmission wheel 312 to rotate. The upper transmission belt 313 drives the upper transmission wheel 314 to rotate, which drives the lower docking gear 315 to rotate. The lifting transmission belt 316 drives the docking gear 107 to rotate. The worm 305 and the worm wheel 306 have a self-locking characteristic, which keeps the electromechanical module stable during the lifting process. The docking gear 107 drives the drive gear 106 to rotate, which drives the sprocket 105 to rotate. The sprocket 105 drives the chain 104 to rotate. The chain 104 drives the lifting plate 103 to rise and fall.

[0040] Since different electromechanical modules require different lifting heights, the height of the lifting frame 201 needs to be adjusted to change the lifting height of the electromechanical modules. The adjusting motor 208 starts the outer transmission wheel 210 to rotate through the output belt 209, and drives the double-acting screw 202 to rotate through the vertical transmission belt 211. The double-acting screw 202 drives the inner threaded sleeve 206 to slide along the double-acting screw 202, thereby driving the lower rotating rod 204 to rotate through the sliding of the side column 207 in the slide groove 205, thereby driving the upper rotating rod 203 to rotate, thereby driving the lifting frame 201 to rise. When the lifting frame 201 rises, it will simultaneously drive the chain 104 to rise. The inner slider 108 slides in the moving frame 101. When adjusting the lifting of the lifting frame 201, the lifting frame 201 drives the upper driven rod 310 to rotate, and the rotation of the upper driven rod 310 drives the lower driven rod 309 to rotate. The lower driven rod 309 rotates relative to the moving frame 101.
