DETAILED DESCRIPTION

[0028] The following is a specific implementation method in conjunction with the drawings.

[0029] Reference Figure 1 , Figure 2 A lifting platform for overhauling a contact network comprises: a base 1, an anti-falling mechanism 2, a support member 3, a moving member 4, a lifting mechanism 6 and an operating platform 9, wherein the support member 3 is arranged at the bottom of the base 1, the moving member 4 is arranged on the support member 3, and the moving member 4 is adapted to the track of the contact network to be overhauled; the lifting mechanism 6 is arranged on the base 1, and the operating platform 9 is arranged on the lifting mechanism 6; the anti-falling mechanism 2 is arranged on the base 1; wherein the anti-falling mechanism 2 is used to intercept tools or parts falling from the upper part of the base 1 during the overhaul process.

[0030] In some embodiments, the anti-fall mechanism 2 includes a storage mechanism, a fixing mechanism and a first protective member 206, the storage mechanism and the fixing mechanism are both arranged on the base 1, the first protective member 206 is movably connected to the storage mechanism, and the first protective member 206 is detachably connected to the fixing mechanism; wherein the first protective member 206 is used to intercept tools or parts that fall from the upper part of the base 1 during the maintenance process when unfolded. The anti-fall mechanism 2 is designed to be a structure that is easy to unfold and fold to meet the needs of the lifting platform at different operation stages. The storage mechanism can be a reel or slide rail system fixed to the edge of the base 1, which is used to store the first protective member 206 when not in use. The first protective member 206, such as a mesh or plate-shaped protective structure, is movably connected to the storage mechanism through a reel or slide rail, so that it can be smoothly unfolded or folded. The fixing mechanism can be a set of hooks, buckles or other locking devices arranged on the base 1, which are used to fix the unfolded first protective member 206 when needed. The edge or specific position of the first protective member 206 is designed with a connector that matches the fixing mechanism, such as a hook ring, a buckle groove, etc., so that the first protective member 206 can be firmly fixed around the base 1 after being unfolded, forming an effective protective barrier. When the lifting platform is undergoing maintenance work, the maintenance personnel first unfold the first protective member 206 from the storage mechanism, and then connect and fix it with the fixing mechanism. In this way, even if the tool or part accidentally falls from the operating table 9 or the lifting mechanism 6, it will be caught by the first protective member 206 to prevent it from falling into the track or railway tunnel, thereby ensuring the safety and efficiency of the maintenance work. The positioning member 5 is used to locate the installation position of the lifting mechanism. By setting the anti-fall mechanism 2, especially the unfolding and fixing of the first protective member 206, the tools or parts that may fall during the maintenance process are effectively intercepted, avoiding potential safety hazards. The design of the storage mechanism and the fixing mechanism allows the first protective member 206 to be easily unfolded and folded, adapting to the needs of the lifting platform at different operation stages and improving the utilization rate of the equipment.

[0031] In some embodiments, several anti-falling mechanisms 2 can be provided, and several anti-falling mechanisms 2 are distributed around the base 1. The number and distribution position of the anti-falling mechanisms 2 can be determined according to the size, shape and expected maintenance operation range of the lifting platform. For example, if the base 1 is a rectangular structure, an anti-falling mechanism 2 can be provided at each of its four corners and the midpoint of each side, so as to ensure the comprehensiveness of the protection and maintain the stability and aesthetics of the structure. If the base 1 is circular or other irregular shapes, the anti-falling mechanisms 2 can be reasonably distributed according to its circumference and area to ensure that the entire working area is covered without dead angles. Each anti-falling mechanism 2 has an independent storage mechanism, a fixing mechanism and a first protective member 206, so that it can be quickly deployed and fixed when needed to form a complete protective barrier. By providing multiple anti-falling mechanisms around the base, tools or parts falling from the lifting platform can be fully intercepted to prevent them from falling into the track or railway tunnel, thereby greatly reducing the safety risks during the maintenance operation.

[0032] In some embodiments, reference Figure 3 , Figure 4 The storage mechanism includes a storage chamber 201, a telescopic guide 202 and a sliding member 205. The storage chamber 201 is arranged in the base 1. The storage chamber 201 is provided with a storage chamber opening. The telescopic guide 202 is slidably connected to the storage chamber 201. The telescopic guide 202 is provided with a slide groove. The sliding member 205 is slidably connected to the slide groove. The first protective member 206 is connected to the slide groove. The volume of the first protective member 206 is smaller than the volume of the storage chamber 201. The storage chamber 201 is cleverly arranged inside the base 1, which not only saves the external space of the lifting platform, but also ensures the safe storage of the first protective member 206 when not in use. The telescopic guide 202 can be a telescopic structure, which provides stable guidance and support for the deployment and storage of the first protective member 206.

[0033] In some embodiments, reference Figure 6, a limiting member 204 is provided on the sliding member 205, and a limiting groove 203 is provided at the opening of the storage cavity, and the limiting member 204 corresponds to the limiting groove 203. The limiting member 204 can be a protrusion, a buckle or other structure that can limit sliding. At the same time, a limiting groove 203 is correspondingly provided at the edge of the opening of the storage cavity, and the shape and position of the limiting groove 203 match the limiting member 204, ensuring that when the sliding member 205 slides to the opening of the storage cavity, the limiting member 204 can be accurately snapped into the limiting groove 203. When the first protective member 206 is completely received in the storage cavity 201, the sliding member 205 moves to the opening of the storage cavity. At this time, the limiting member 204 is tightly combined with the limiting groove 203, which plays a role of double fixing. This design not only enhances the stability of the first protective member 206 in the stored state and prevents it from accidentally sliding out during transportation or storage, but also provides a clear visual indication for maintenance personnel before unfolding the first protective member 206 to ensure the safety and accuracy of the operation.

[0034] In some embodiments, the fixing mechanism includes: a first fixing member 207, a first connecting member 208, a telescopic member 209, a locking mechanism, and a second fixing member 212. The first fixing member 207 is arranged on the base 1, the first fixing member 207 is connected to the first connecting member 208, the two ends of the telescopic member 209 are respectively connected to the first connecting member 208 and the locking mechanism, the second fixing member 212 is arranged on the first protective member 206, and the locking mechanism is detachably connected to the second fixing member 212. The first fixing member 207 can be a bolt, a nut or other fixing device, which is used to provide a stable support for the first connecting member 208. The first connecting member 208 can be a connecting plate, a connecting rod or other connecting structure, which is used to connect the telescopic member 209 to the base 1. The telescopic member 209 can be a telescopic rod or other telescopic device, which is used to provide the flexibility and stability required for adjusting and fixing the first protective member 206. The second fixing member 212 can be a hook, a buckle or other connecting device, which is used to be detachably connected with the locking mechanism. The locking mechanism can be a lock buckle, a lock ring or other locking device, which is used to ensure the stability and safety of the first protective member 206 in the unfolded state. The design of the fixing mechanism enables the first protective member 206 to be firmly fixed around the base 1 after being unfolded, effectively preventing tools or parts that may fall during the maintenance process from harming personnel and equipment, and improving the safety of the maintenance work. The introduction of the telescopic member 209 enables the fixing mechanism to have a certain adjustment ability, which can be adjusted according to different maintenance needs and working environments, thereby improving the adaptability and flexibility of the lifting platform.

[0035] In some embodiments, reference Figure 5, the locking mechanism includes a second connecting member 210 and a buckle 211, a second fixing member 212 is provided with a slot 213, the second connecting member 210 is connected to the telescopic member 209, the buckle 211 is detachably connected to the second connecting member 210, and the buckle 211 is adapted to the slot 213. The buckle 211 is designed to be detachable, and can be easily connected or disconnected with the second connecting member 210 to meet the fixing and release requirements of the first protective member 206. In actual operation, when it is necessary to fix the first protective member 206, the maintenance personnel first unfold the first protective member 206 from the storage mechanism, and then adjust the positions of the second connecting member 210 and the buckle 211 through the telescopic member 209, so that the buckle 211 can be accurately aligned with the slot 213 on the second fixing member 212. Then, the buckle 211 is firmly inserted into the slot 213, thereby achieving the fixing of the first protective member 206. Through the close fit between the buckle 211 and the slot 213, the first protective member 206 can be firmly fixed around the base 1 to form an effective protective barrier, which greatly reduces the risk of tools or parts falling from the lifting platform during maintenance and improves the safety of maintenance work.

[0036] In some embodiments, a second guard 214 is provided at the edge of the first guard 206; wherein the second guard 214 is used to prevent tools or parts from rolling off the first guard 206. The second guard 214 can be designed in a variety of shapes and materials to meet different protection requirements. For example, the second guard 214 can be a flange, a rib or a fence structure provided along the edge of the first guard 206. These structures can effectively prevent tools or parts from rolling off the edge of the first guard 206. The second guard 214 can be firmly mounted on the edge of the first guard 206 by welding, bolting, snap-fitting or other fixing methods. The first guard 206 and the second guard 214 can be made of rubber or composite materials.

[0037] In some embodiments, the first protective member 206 and the second protective member 214 can be a double-layer structure, wherein the first layer is an elastic mesh structure and the second layer is a solid layer structure, wherein the first layer provides buffering protection for falling tools or parts and the second layer provides blocking for falling tools or parts.

[0038] In some embodiments, a box 7 is provided on the base 1, and a counterweight 8 is provided inside the box 7. The box 7 can be made of metal or high-strength composite materials to ensure that it can bear the weight of the counterweight 8 and maintain structural integrity in various harsh environments. The shape and size of the box 7 can be customized according to the overall design and counterweight requirements of the lifting platform to maximize its space utilization and stability contribution. The counterweight 8 can be made of high-density, wear-resistant materials such as cast iron, concrete or high-density plastic. The selection of these materials is intended to ensure that the counterweight 8 has sufficient weight to provide the required stability while maintaining its durability and easy handling characteristics. The shape and number of the counterweight 8 can also be adjusted according to the size, load capacity and stability requirements of the lifting platform. During the assembly process, the box 7 is firmly fixed in the appropriate position of the base 1 to ensure that it will not move or tilt during use. The counterweight 8 is placed inside the box 7 according to a predetermined configuration to achieve the desired stability effect. By setting the box 7 on the base 1 and configuring the counterweight 8, we can effectively increase the overall weight of the lifting platform, thereby reducing the risk of shaking and tilting during operation. This is crucial to ensure the safety of maintenance personnel on the operating table and to improve the accuracy of maintenance work.

[0039] In some embodiments, the operating platform 9 is a box structure, and the top of the operating platform 9 is open. The box structure of the operating platform 9 is made of sturdy and durable materials, such as metal or high-strength composite materials, to ensure that it can withstand various loads and pressures that may be generated during the maintenance process. The shape and size of the operating platform 9 are customized according to the overall layout of the lifting platform and the specific needs of the maintenance work to maximize space utilization and work efficiency. The top of the operating platform 9 is designed to be open so that maintenance personnel can easily enter and exit and operate. The size and shape of the opening are optimized according to the body shape and work requirements of the maintenance personnel to ensure that they have enough space to move and work during the operation. The box structure provides maintenance personnel with a relatively closed and stable working environment, which helps to reduce the occurrence of accidents. At the same time, the open design allows maintenance personnel to clearly see the surrounding environment and working conditions, thereby enhancing the safety of the operation.

[0040] In some embodiments, an opening is provided on the side of the operating platform 9, and the opening can be located on any one or both sides of the operating platform, depending on the layout of the lifting platform and the actual needs of the maintenance work. A protective door 10 is hinged at the opening, and a handle 11 is provided on the protective door 10, and a door lock 12 is provided on the inner and outer sides of the protective door 10. The handle 11 is provided on the protective door 10 so that the maintenance personnel can easily hold and operate the protective door. The door lock 12 can be a mechanical lock, an electronic lock or other types of locking devices, depending on the safety requirements of the lifting platform and the specific environment of the maintenance work. The design of the door lock 12 is to ensure that the protective door can be firmly locked at the opening in the closed state to prevent accidental opening that may occur during the maintenance process. At the same time, the door lock 12 also facilitates the maintenance personnel to quickly and conveniently open or close the protective door when needed. Through the design of the side opening and the protective door, the maintenance personnel can easily enter and exit the operating platform and perform various maintenance operations. This greatly reduces the number of times they move and turn during the operation, thereby improving the work efficiency.
