[0001] This invention relates to the field of work platform technology, and in particular to a fall-prevention work platform for pipe gallery installation. Background Technology
[0002] In the construction and maintenance of utility tunnels in municipal, chemical, and power industries, workers often need to perform pipeline installation, welding, and maintenance operations at heights or in confined spaces. Traditional work platforms (such as elevators) often have insufficient protection and poor stability, leading to a high risk of falls for workers. Especially in confined spaces, poor lighting, or slippery environments within utility tunnels, slips, instability, or missteps are frequent occurrences, threatening not only construction safety but also potentially affecting project progress and quality.

[0013] Further, the retainer ring is an elastic rubber ring.
[0014] Further, the anti-falling mechanism is provided with at least two, both of which are connected with the same retainer ring and are distributed at intervals around the circumference of the retainer ring.
[0015] Further, the linear driving mechanism comprises a motor and a screw rod, the motor and the screw rod are connected in sequence in the vertical direction, the screw rod is arranged in the vertical direction, the working platform is drivingly connected with the screw rod, and the motor is used to drive the screw rod to rotate to drive the working platform to displace in the vertical direction.
[0016] Further, the pipe gallery pipeline installation anti-falling operation platform further comprises a movable base and a liftable support frame, the linear driving mechanism and the liftable support frame are both mounted on the movable base and supported by the movable base, and the two ends of the liftable support frame are respectively abutted with the movable base and the working platform.

[0020] Compared with the prior art, the application has the beneficial effects that:
[0021] 1. Based on the cooperation design of the rotating assembly and the first telescopic rod, the core is to give the dynamic following ability and the operation freedom of the anti-falling mechanism. The rotating assembly allows the first telescopic rod to flexibly rotate in the horizontal and vertical directions, and in combination with the free extension and contraction characteristics of the first telescopic rod, the guard ring connected to the worker can almost follow the all-around working posture changes of the worker in real time without obstruction. When the worker needs to move position in the platform containing space, bend down for pipeline alignment, turn side for tool operation or turn around for material taking and placing, the movement of the guard ring will naturally pull the first telescopic rod to make corresponding length adjustment, and the angle direction is smoothly changed through the rotating assembly. This design eliminates the strict limitation and the bondage feeling generated by the traditional fixed length safety rope or rigid guide rail on the movement range of the worker, so that the worker is more flexible when performing fine and complex pipeline installation operation, and the work efficiency and operation comfort are greatly improved.
[0022] 2. More importantly, this dynamic following mechanism ensures that the first telescopic rod is always in a moderate pre-tightening state, neither too loose to fail or entangled, nor too tight to hinder necessary movements. In the event of a critical accidental fall, after the telescopic rod reaches the maximum length (not exceeding the safe working range of the working platform), the force of the falling worker will be transmitted to the rotating assembly firmly installed on the working platform through the guard ring and the first telescopic rod which are already in the following state, and the force will be borne by the whole working platform to limit the falling position of the worker within the safe area. Therefore, the cooperation of rotation and telescoping not only optimizes the daily operation experience, but also reliably protects the worker in critical moments, and improves the overall safety level of high-altitude pipeline installation operation in the pipe gallery.

The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0030] Reference Figs. 1-3The pipe installation anti-falling work platform of the pipe gallery of the preferred embodiment of the present application comprises a work platform 1, a linear driving mechanism 3, at least one anti-falling mechanism 4 and a guard ring 5. The work platform 1 has a containing space 2. The work platform 1 has a bottom plate 101 and a guardrail 102 which enclose the containing space 2. The work platform 1 is connected with the linear driving mechanism 3 and is supported by the output part of the linear driving mechanism 3. The linear driving mechanism 3 is used to drive the work platform 1 to displace in the vertical direction. The anti-falling mechanism 4 is arranged in the containing space 2. Each anti-falling mechanism 4 comprises a rotating assembly 401 and a first telescopic rod 402. The rotating assembly 401 is connected with one end of the first telescopic rod 402. The rotating assembly 401 allows the first telescopic rod 402 to rotate in the horizontal or vertical direction. The guard ring 5 is connected with the other end of the first telescopic rod 402. The guard ring 5 is worn by the worker. The first telescopic rod 402 extends, contracts or rotates in the movement direction of the guard ring 5 in the containing space 2.
[0031] The working principle of the present application is as follows: The output part of the linear driving mechanism 3 drives the work platform 1 to accurately lift in the vertical direction, so that the worker can conveniently reach the different height positions required for the pipe gallery pipe installation to work. When the worker operates in the platform containing space 2, at least one anti-falling mechanism 4 is equipped in addition to the basic protection of the work platform 1 bottom plate 101 and the guardrail 102. The worker needs to correctly wear the guard ring 5 which is connected with the rotating assembly 401 installed in the platform through the first telescopic rod 402. The rotating assembly 401 allows the first telescopic rod 402 to flexibly rotate in the horizontal and vertical directions. When the worker moves, bends or turns on the platform to perform the installation operation, the guard ring 5 moves, and the first telescopic rod 402 extends, contracts or rotates to dynamically adjust the length and angle, so as to ensure that the anti-falling connection always maintains a moderate tension state, and to minimize the feeling of restraint on the worker and the limitation of necessary operation. The core protection mechanism is that once the worker slips, the guard ring 5 will bear the falling force. The first telescopic rod 402 will be locked and cannot be extended to a certain length after extending in the movement direction of the guard ring 5, and then the force is transmitted to the rotating assembly 401 through the first telescopic rod 402, and finally borne by the anti-falling mechanism 4 base firmly installed on the stable work platform 1. The slipping distance is strictly limited in the containing space 2, which effectively prevents it from falling out of the work platform 1, and realizes the safety protection of high-altitude work.
[0032] Obviously, based on the cooperation design of rotating assembly 401 and first telescopic rod 402, its core lies in its dynamic following ability and operation freedom given to the anti-falling mechanism 4. The rotating assembly 401 allows the first telescopic rod 402 to rotate flexibly in horizontal and vertical directions, and in combination with the free extension and contraction characteristics of the first telescopic rod 402 itself, the connecting guard ring 5 of the worker can almost follow the real-time changes of the worker's all-around working posture without obstruction. When the worker needs to move position in the platform accommodating space 2, bend down for pipeline alignment, turn side to operate tools or turn around to take and place materials, the movement of the guard ring 5 will naturally lead the first telescopic rod 402 to make corresponding telescopic adjustment in length, and smoothly change the angle direction through the rotating assembly 401. This design eliminates the strict restrictions and resulting bondage of the traditional fixed-length safety rope or rigid guide rail on the range of personnel activities, making the worker more flexible when performing fine and complex pipeline installation operations, and greatly improving the work efficiency and operation comfort.
[0033] More importantly, this dynamic following mechanism ensures that the first telescopic rod 402 is always in a moderately pre-tensioned state, neither too loose to fail or entangle, nor too tight to hinder necessary movements. In the event of a critical accidental fall, after the telescopic rod reaches the maximum length (not exceeding the safe working range of the working platform 1), the force of the falling personnel will be transmitted to the rotating assembly 401 firmly installed on the working platform 1 through the guard ring 5 and the first telescopic rod 402 which are already in the following state, and the entire working platform 1 will bear the force, limiting the falling position of the worker within the safe area. Therefore, this cooperation of rotation and telescoping not only optimizes the daily operation experience, but also provides reliable protection for the worker in critical moments, improving the overall safety level of high-altitude pipeline installation operations in pipe galleries.
[0034] In this embodiment, the design of the safety harness 5 in the fall protection platform directly affects the safety and operation experience of the workers, and is the core carrier of the individual protection performance. The ergonomic design ensures the comfort and stability of wearing, and the safety harness 5 can be worn on the hands, feet or torso. In this embodiment, the safety harness 5 is preferably worn on the waist. Compared with the traditional full-body safety belt, this safety harness 5 focusing on core torso support significantly reduces the feeling of restraint and reduces fatigue after long-term wearing, making the workers more tolerant in the high temperature and humid environment of the pipe gallery. The safety harness 5 is the only interface connecting the worker and the fall protection mechanism 4, and its structural strength and reliability are crucial. High-strength lightweight materials are used to ensure that the safety harness 5 can effectively withstand the huge impact force in the falling moment. In particular, the flexible connection point design of the safety harness 5 and the first telescopic rod 402, combined with its own low friction characteristics, is the basis for realizing "dynamic and inductive following". Whether the worker is bending down for pipeline welding, turning sideways to tighten the bolt, or quickly turning around to pick up tools, the safety harness 5 can smoothly slide or slightly rotate at the worker's waist, minimizing the obstruction and pulling sensation of the action, eliminating the pulling of the traditional safety belt due to the fixed connection point, and greatly improving the operation freedom and concentration.
[0035] In this design, further, the safety harness 5 can be integrated with quick adjustment and locking buckles, so that workers of different body types can quickly and accurately complete wearing and tightness adjustment, simplifying the operation process, improving work efficiency and ensuring the adaptability of each use. In the fall protection mechanism, the wide support surface design of the safety harness 5 can more evenly distribute the impact force to the strong skeletal area of the worker's waist, significantly reducing the risk of internal organ damage or lumbar injury caused by concentrated impact force, and providing higher level of human protection.
[0036] More preferably, the rotating assembly 401 comprises a mounting base 411, a first hinged shaft 412, a first connecting block 418, a second hinged shaft 413 and a second connecting block 414, the mounting base 411 is mounted in the accommodating space 2, the first hinged shaft 412 is connected with and supported by the mounting base 411, the first hinged shaft 412 extends in the vertical direction, the first connecting block 418 is connected with the first hinged shaft 412 so that the first connecting block 418 rotates around the axis of the first hinged shaft 412 in the horizontal direction, the second hinged shaft 413 is connected with the first connecting block 418, the second hinged shaft 413 extends in the horizontal direction, the second connecting block 414 is connected with the second hinged shaft 413 so that the second connecting block 414 rotates around the axis of the second hinged shaft 413 in the vertical direction, and the second connecting block 414 is connected with the first telescopic rod 402. The biaxial hinged structure of the rotating assembly 401 provides precise motion control of the fall protection mechanism 4 in all directions through the cooperation of the first hinged shaft 412 (vertical direction) and the second hinged shaft 413 (horizontal direction). The horizontal rotation of the first connecting block 418 around the vertical shaft (first degree of freedom) enables the first telescopic rod 402 to follow the lateral movement of the worker, and the vertical rotation of the second connecting block 414 around the horizontal shaft (second degree of freedom) adapts to the change in posture of the worker when bending over or standing up. The mechanical advantage of the orthogonal biaxial design is that the two rotation dimensions do not interfere with each other, avoiding mechanism jamming during compound motion; the path of the falling impact force through the second connecting block 414, the second hinged shaft 413, the first connecting block 418 and the first hinged shaft 412 in turn gradually conducts the instantaneous load to the mounting base 411, thereby reducing the instantaneous load; compared with the universal joint structure, the layered hinged modular design saves installation space, and is especially suitable for narrow environments such as pipe galleries. In addition, the vertical arrangement of the first hinged shaft 412 can naturally bear the suspended weight of the telescopic rod, and the horizontal positioning of the second hinged shaft 413 ensures that the guard ring 5 still rotates smoothly when the worker leans forward, thereby achieving horizontal dead angle-free and pitch zero-resistance fall protection experience.
[0037] More preferably, the first telescopic rod 402 comprises a first sleeve 415, a second sleeve 416 and a clamp 417, the first sleeve 415 and the second sleeve 416 are mutually sleeved, the first sleeve 415 is connected with the rotating assembly 401, and the two ends of the clamp 417 are respectively connected with the second sleeve 416 and the guard ring 5. In this embodiment, the clamp 417 structure realizes quick replacement and maintenance of the guard ring 5, greatly shortens the equipment maintenance time, and also enables replacement of different specifications of the guard ring 5 to adapt to different working environments.
[0038] More preferably, the guard ring 5 is made of elastic rubber. The guard ring 5 is made of high-elasticity rubber or silicone material, which can adapt to the waist curve of workers of different body types, ensuring comfort while maintaining the guard ring 5 in the optimal working position through the pre-tightening force generated by elastic deformation. This elastic property allows the guard ring 5 to automatically adjust the contact pressure when the person is moving, avoiding the local compression discomfort that may be caused by traditional rigid guard rings 5, and ensuring effective force transmission when a fall occurs. The elastic material also has excellent energy absorption characteristics, which can absorb part of the energy under impact load by deformation, reducing the risk of injury to the worker's waist caused by instantaneous impact. In addition, the elastic rubber ring has good environmental resistance and is not affected by the harsh working conditions such as moisture and oil in the pipe gallery, and the surface texture design provides reliable anti-slip performance, ensuring stable connection in various working postures. This design not only improves safety performance, but also significantly improves comfort during long-term wear.
[0039] More preferably, the fall protection mechanism 4 is provided with at least two, both of which are connected to the same guard ring 5 and are distributed around the circumference of the guard ring 5. Through the synchronous extension and rotation of the two first extension rods 402 of the fall protection mechanism 4, the guard ring 5 is always maintained in the optimal working position. This symmetrical design not only balances the impact load and significantly reduces the load on a single mechanism, but more importantly, it establishes a reliable redundant protection mechanism - when any mechanism fails unexpectedly, the other system can still provide complete fall protection independently. In actual operation, the two fall protection mechanisms 4 work together to effectively suppress the abnormal swinging and rotation of the guard ring 5, providing a more stable and natural movement experience for the worker.
[0040] More preferably, the linear drive mechanism 3 comprises a motor 301 and a lead screw 302 connected in sequence along the vertical direction, the lead screw 302 is arranged to extend along the vertical direction, the work platform 1 is drivingly connected with the lead screw 302, and the motor 301 is used to drive the lead screw 302 to rotate to drive the work platform 1 to displace in the vertical direction. The transmission mode of the motor 301 driving the lead screw 302 to rotate has self-locking characteristics, which can automatically maintain the platform position in the case of power failure, effectively preventing the risk of accidental sliding. The rigid extension design of the lead screw 302 along the vertical direction ensures the linearity of the platform lifting track, avoiding the deflection phenomenon that may be caused by traditional hydraulic or chain drive. This structure is particularly suitable for pipe gallery working environment, and its closed transmission system can resist the erosion of humid, dusty and other harsh working conditions, has low maintenance requirements and long service life. The direct connection mode of the motor 301 and the lead screw 302 has high transmission efficiency, and can realize high positioning accuracy with the cooperation of an intelligent control system, meeting the fine operation requirements of different height pipe installation. The whole drive mechanism runs smoothly and quietly, and the stepless speed regulation characteristic makes the platform lifting process more safe and controllable, significantly improving the efficiency and safety of high-altitude operation.
[0041] More preferably, the pipe gallery pipe installation anti-falling work platform further comprises a mobile base 6 and a liftable support frame 7, the linear drive mechanism 3 and the liftable support frame 7 are both installed on and supported by the mobile base 6, and the two ends of the liftable support frame 7 are respectively in abutment with the mobile base 6 and the work platform 1. The innovative design of the mobile base 6 and the liftable support frame 7 greatly improves the stability and maneuverability of the work platform. The mobile base 6 provides a solid load-bearing foundation for the entire system, and is usually equipped with universal wheels and locking mechanisms at the bottom, allowing the platform to move flexibly and be fixed quickly within the pipe gallery. The liftable support frame 7 and the linear drive mechanism 3 form a double support system, when the work platform 1 is lifted, the support frame adjusts the height synchronously and maintains stable contact with the platform, effectively dispersing the platform load and reducing the stress burden of the lead screw 302 drive mechanism. This design not only enhances the anti-overturning ability of the platform at the maximum extension height, but also provides additional support protection in the case of sudden load. Further, the support frame adopts a hydraulic machine or a folding lifting structure, which has a self-locking function and can work cooperatively or independently with the main drive system. The modular design of the mobile base 6 facilitates quick disassembly and transportation, providing higher convenience for pipe gallery pipe installation operations.
[0042] More preferably, the mobile base 6 has a receiving cavity 8 for receiving the working platform 1 and the liftable support frame 7. The receiving cavity 8 of the mobile base 6 is designed to achieve compact storage and rapid deployment of the equipment through integrated structure. The customized spatial layout of the receiving cavity 8 enables the working platform 1 and the liftable support frame 7 to be completely embedded inside the base in the non-working state, not only greatly reducing the overall occupied space, facilitating transportation and turnover in narrow pipe gallery passages, but also more importantly providing all-round protection for key components. This design solves the pain point of inconvenient transportation of traditional overhead working equipment, and is particularly suitable for pipe gallery construction environments that need to be frequently transferred to different workstations.
[0043] More preferably, the mobile base 6 is also provided with an auxiliary support mechanism 9, which includes a second telescopic rod 901 and a pull rod 902. The two ends of the second telescopic rod 901 are respectively hinged to the mobile base 6 and the working platform 1, and the two ends of the pull rod 902 are respectively connected to the middle part of the second telescopic rod 901 and the working platform 1. The auxiliary support mechanism 9 improves the overturning resistance and load balance of the working platform 1 through a triangular stabilizing structure. The hinged design of the second telescopic rod 901 and the working platform 1 forms a variable-angle support, which automatically adjusts the support angle during the lifting of the platform and always maintains the best stress state. The connection of the pull rod 902 and the middle part of the second telescopic rod 901 forms a stable triangular reinforcing structure, which can effectively suppress the shaking of the platform and directly transfer the additional load to the mobile base 6 when the platform is subjected to eccentric load or the operator moves. The adjustable length of the second telescopic rod 901 enables the auxiliary support to adapt to different heights of the platform position, and the hinged connection avoids interference of the support structure with the free lifting of the platform. Especially when the platform is extended to the maximum height or heavy pipeline installation is performed, the auxiliary support mechanism 9 can work cooperatively with the main support system to disperse the load through multiple paths, greatly improving the stability of the platform and providing additional safety protection for high-risk operations. The entire mechanism adopts a lightweight design and is completely accommodated within the base profile when retracted, without affecting the mobility of the equipment.
[0044] More preferably, the second telescopic rod 901 includes a third sleeve 911 and a fourth sleeve 912. One end of the third sleeve 911 is hinged to the mobile base 6, and one end of the fourth sleeve 912 is hinged to the working platform 1. The other ends of the third sleeve 911 and the fourth sleeve 912 are mutually sleeved. Multiple positioning holes and spring pin mechanisms can be provided between the sleeves, which allow quick locking of the preset length to adapt to the support requirements of different working heights. The special feature of this design is that mechanical length adjustment is used instead of complex power systems, which greatly reduces the failure rate and maintenance requirements while ensuring the support effect. When the platform is in a non-working state, the sleeves can be completely retracted, cooperatively folded with the pull rod 902 into a compact form to reduce the occupied space.
