Description

Technical Field

[0001] This utility model relates to the technical field of railway construction equipment, specifically to an anti-throw net installation vehicle with a suspended basket. Background Technology

[0002] The installation of anti-throw netting across busy railway trunk lines is a crucial construction step in ensuring railway operational safety. Its core requirement is to efficiently complete the installation while ensuring the normal and safe operation of the existing railway trunk line. This construction scenario has significant unique characteristics: Firstly, the railway trunk line is in a "busy" operation state, with high train frequency and density. Construction must be strictly limited to "maintenance windows" (i.e., specific time periods when no trains are passing through), a time window that is extremely limited, typically only a few hours, placing extremely high demands on construction efficiency. Secondly, the construction area is adjacent to existing railway facilities, including critical equipment such as communication antennas and overhead contact lines. The spatial environment is complex, and it falls into the category of high-altitude, edge-prone high-risk operations, making safety risk management extremely difficult.

[0003] The current mainstream construction method in the industry is the "crane-suspended basket" method. Although this method is mature in the installation of anti-throw nets on ordinary highways, it exposes many unavoidable defects when applied to the scenario of crossing a busy railway trunk line. The crane needs to be located near the existing railway line station, and the dense communication antennas, catenary and other facilities along the railway line severely compress the crane's operating radius. If the operation is slightly off, it is very easy to cause the crane to collide with the railway facilities, which can lead to major safety accidents such as railway communication interruption and catenary damage. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides an anti-throw net installation vehicle with a suspended basket, which combines an external suspended basket with a mobile device, eliminating dependence on cranes and avoiding the limitations of communication antennas and contact wires along railway lines on the working space.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-throw net installation vehicle with a suspended basket, comprising a suspended basket, the suspended basket being fixedly connected to the top of a vertical support frame, the vertical support frame being fixedly connected to a mobile device, a working elevation platform being fixedly connected to the mobile device, a right clamping plate being fixedly connected to one end of the working elevation platform, a support plate being fixedly connected to the other end of the working elevation platform, a left clamping plate being disposed between the right clamping plate and the support plate, the left clamping plate being slidably disposed on the working elevation platform, and a driving component for driving the left clamping plate to slide being disposed on the support plate.

[0006] The above structural design, using a combination of "mobile device + work elevation platform," replaces the traditional crane-suspended basket construction mode. It eliminates the need for a crane to occupy a large area of ​​standing space and is suitable for the narrow working environment of railway beams. The work elevation platform can directly raise the operating height of construction personnel, making it easier for workers to install anti-throw nets. The clamping structure, with a fixed right clamping plate and a sliding left clamping plate, can clamp vertically placed anti-throw nets. When anti-throw nets are needed, they can be pulled out, and then the drive component can be activated to clamp the remaining anti-throw nets, eliminating the need for manual handling and adjustment of the net positions.

[0007] Preferably, a railing is fixedly connected to the right clamping plate on the side away from the suspended basket, and the railing passes laterally through the left clamping plate.

[0008] With the above structural design, the railing can provide lateral constraint on the sliding trajectory of the left clamping plate, preventing the left clamping plate from shifting or tilting due to uneven force under the drive component. This ensures that the left clamping plate always remains parallel to the right clamping plate, thereby guaranteeing the stability of the anti-throw net during clamping and preventing the net from loosening due to plate displacement. On the other hand, the railing is located on the edge of the work platform away from the suspended basket, forming a protective barrier to prevent the anti-throw net from accidentally falling from this side.

[0009] Preferably, one end of a protective rope is fixedly connected to the side of the right clamping plate near the basket, and the other end of the protective rope is detachably connected to either the support plate or the left clamping plate, or detachably connected to both the support plate and the left clamping plate simultaneously.

[0010] With the above structural design, the protective rope can form targeted protection on the other side of the anti-throw net of the work elevation platform, preventing the anti-throw net from falling from the other side.

[0011] Preferably, the protective rope is slidably connected to the middle of a first locking buckle, the other end of the protective rope is fixedly connected to a second locking buckle, a first locking ring matching the first locking buckle is fixedly connected to the left clamping plate, and a second locking ring matching the second locking buckle is fixedly connected to the support plate.

[0012] The above structural design, through the "lock-lock ring" snap-fit ​​connection, enables the rapid assembly and disassembly of the protective rope compared to traditional knot binding, significantly shortening the time for pre-construction preparation and post-construction storage, and improving work efficiency; the effective length of the protective rope can be flexibly adjusted according to the sliding position of the left clamping plate (i.e., clamping distance) to ensure that the protective rope is always in a taut state, avoiding the reduction of the protection range or loss of blocking effect due to rope slack.

[0013] Preferably, multiple sets of rollers are provided below the left clamping plate, and the rollers are rotatably connected to the working elevation platform.

[0014] The above structural design makes it easier for workers to pull out the anti-throw net.

[0015] Preferably, the drive assembly includes a first scissor arm and a second scissor arm hinged together at their middle portions, a hinge rod rotatably connected at the middle portions of the first scissor arm and the second scissor arm, and a drive rod with one end hinged to the hinge rod. Both ends of the hinge rod are provided with the first scissor arm and the second scissor arm. The upper end of the first scissor arm is hinged to the support plate, and the lower end of the first scissor arm is slidably connected to the left clamping plate. The upper end of the second scissor arm is hinged to the left clamping plate, and the lower end of the second scissor arm is slidably connected to the support plate. The other end of the drive rod is hinged to the left clamping plate. The drive rod is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0016] With the above structural design, the telescopic structure formed by the central hinge of the scissor arm can smoothly convert the linear driving force of the drive rod into the sliding displacement of the left clamping plate. Moreover, the force distribution characteristics of the scissor structure can avoid damage to components caused by excessive force at a single point, thus improving driving stability. By adjusting the extension and retraction of the drive rod, the sliding distance of the left clamping plate can be precisely controlled.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This device combines a mobile unit with an elevated work platform, eliminating the need for a crane to occupy a large area of ​​workspace and making it suitable for the narrow working environment of railway beams. The elevated work platform directly raises the operating height of construction workers, facilitating the installation of anti-throw nets. The combination of the clamping plate and the sliding left clamping plate enables the anti-throw nets to be "grabbed and removed immediately," while the rollers reduce extraction resistance. The drive components precisely control the clamping distance, greatly simplifying the process of transferring and fixing the netting. The quick-assembly and disassembly design of components such as protective ropes and locks further shortens the process connection time, allowing more installations to be completed within the limited time of "track openings."

[0019] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a technical solution: an anti-throw net installation vehicle with a suspended basket, including a suspended basket 1, the suspended basket 1 being fixedly connected to the top of a vertical support frame 2, the vertical support frame 2 being fixedly connected to a moving device 3, a working elevation platform 4 being fixedly connected to the moving device 3, a right clamping plate 6 being fixedly connected to one end of the working elevation platform 4, a support plate 7 being fixedly connected to the other end of the working elevation platform 4, a left clamping plate 8 being disposed between the right clamping plate 6 and the support plate 7, the left clamping plate 8 being slidably disposed on the working elevation platform 4, and a driving component for driving the left clamping plate 8 to slide being disposed on the support plate 7.

[0020] The mobile device 3 includes a base 31, and a plurality of casters are fixedly connected to the bottom of the base 31. The casters are equipped with brakes to facilitate the movement of the device.

[0021] Multiple support columns 32 are provided between the working platform 4 and the mobile device 3. The lower end of the support column 32 is fixedly connected to the mobile device 3, and the upper end of the support column 32 is fixedly connected to the bottom surface of the working platform 4.

[0022] Diagonal bracing is installed between the support frame 2 and the work elevation platform 4 to enhance the stability of the support frame 2.

[0023] When loading the anti-throw net, the anti-throw net is vertically loaded between the right clamping plate 6 and the left clamping plate 8. When the anti-throw net is needed, the left clamping plate 8 can be moved to the left to loosen it first, and then the staff can pull out the anti-throw net. Next, the staff can start the drive component to clamp the remaining anti-throw net between the right clamping plate 6 and the left clamping plate 8.

[0024] The right clamping plate 6 is fixedly connected to the side away from the basket 1 with a railing 61. Multiple railings 6 are provided. The right end of the railing 61 is fixedly connected to the right clamping plate 6, and the left end of the railing 61 is fixedly connected to the support plate 7. The railing 61 passes laterally through the left clamping plate 8.

[0025] One end of the protective rope 62 is fixedly connected to the side of the right clamping plate 6 near the basket 1. Multiple protective ropes 62 are provided (generally no more than 3 protective ropes 62 are provided to save operation time). The other end of the protective rope 62 can be detachably connected to either the support plate 7 or the left clamping plate 8, or can be detachably connected to both the support plate 7 and the left clamping plate 8 at the same time.

[0026] The protective rope 62 is slidably connected to the first buckle 63 in the middle, and the other end of the protective rope 62 is fixedly connected to the second buckle 64. The left clamping plate 8 is fixedly connected to the first locking ring 65 that matches the first buckle 63, and the support plate 7 is fixedly connected to the second locking ring 66 that matches the second buckle.

[0027] Multiple sets of rollers 41 are provided below the left clamping plate 8, and the rollers 41 are rotatably connected to the working heightening platform 4.

[0028] The drive assembly includes a first scissor arm 71 and a second scissor arm 72 hinged together at their midpoints, a hinge rod 73 rotatably connected at the midpoints of the first scissor arm 71 and the second scissor arm 72, and a drive rod 74 with one end hinged to the hinge rod 73. The hinge rod 73 has a first scissor arm 71 and a second scissor arm 72 at both ends. The upper end of the first scissor arm 71 is hinged to the support plate 7, and the lower end of the first scissor arm 71 is slidably connected to the left clamping plate 8. The upper end of the second scissor arm 72 is hinged to the left clamping plate 8, and the lower end of the second scissor arm 72 is slidably connected to the support plate 7. The other end of the drive rod 74 is hinged to the left clamping plate 8. The lower ends of the first scissor arms 71 are connected together by a first connecting rod 77, and the lower ends of the second scissor arms 72 are connected together by a second connecting rod 78.

[0029] The drive rod 74 is a hydraulic cylinder, pneumatic cylinder, or electric push rod.

[0030] The lower end of the first scissor arm 71 is rotatably connected to the first rolling column 711, which is slidably connected to the first guide rail 70 that matches it. The first guide rail 70 is fixedly connected to the left clamping plate 8. The lower end of the second scissor arm 72 is rotatably connected to the second rolling column 712, which is slidably connected to the second guide rail 79 that matches it. The second guide rail 79 is fixedly connected to the support plate 7. Both the first guide rail 70 and the second guide rail 79 are concave grooves.

[0031] Working principle: Anti-throw net loading 1) Clamping gap adjustment: Start the drive assembly, and the extension and retraction of the drive rod 74 drives the hinge rod 73 to move. The drive rod 74 retracts, pushing the hinge rod 73 to move closer to the support plate 7, causing the first scissor arm 71 and the second scissor arm 72 to retract. The first rolling column 711 slides along the first guide rail 70 and the second rolling column 712 slides along the second guide rail 79, thereby driving the left clamping plate 8 to slide away from the right clamping plate 6, expanding the clamping gap between the two until the gap is slightly larger than the overall width of the multiple anti-throw nets to be loaded.

[0032] 2) Vertical loading of anti-throw net: The worker vertically places the anti-throw net between the right clamping plate 6 and the left clamping plate 8, ensuring that the net is vertically attached to the inner side of the two clamping plates; then the drive rod 74 is operated in reverse to extend the first scissor arm 71 and the second scissor arm 72 to open, and the left clamping plate 8 slides towards the right clamping plate 6 until the two clamping plates clamp the anti-throw net tightly. The clamping force should be such that the net does not loosen or deform.

[0033] 3) Layout of protective structure: The first buckle 63 in the middle of the sliding protective rope 62 is engaged with the first locking ring 65 on the left clamping plate 8, and the second buckle 64 at the end of the protective rope 62 is engaged with the second locking ring 66 on the support plate 7 to achieve double-sided protection and prevent the net from falling during transportation.

[0034] Positioning adjustment 1) Equipment movement and positioning: Release the universal wheel brake, and 2-3 workers push the equipment along the railway beam surface. Utilize the flexibility of the moving device 3 to shuttle between facilities such as communication antennas and contact wires, and accurately push the equipment to the designated position for the anti-throw net installation. After reaching the position, immediately lock the universal wheel brake. At the same time, temporary pads can be added to both sides of the base 31 to further improve the stability of the equipment and prevent the equipment from shifting during operation.

[0035] 2) Personnel positioning and preparation: Workers can directly connect to the installation position by standing on the work elevation platform 4. One worker enters the suspended basket 1 to check whether the guardrails (if any) around the suspended basket 1 are secure and prepare the installation tools. One to two workers are reserved on the platform to be responsible for the transfer of the mesh and the monitoring of the equipment, forming a division of labor and cooperation mode.

[0036] Mesh Removal and Installation Stage 1) Net loosening and extraction: The operator on the platform operates the drive assembly, slightly shortens the drive rod 74, and moves the left clamping plate 8 slightly to the left, loosening the anti-throw net (the degree of loosening should be such that the net can be easily extracted without slipping off on its own), and unlocks the first locking ring 65 and the second locking buckle 64; the roller 41 under the left clamping plate 8 plays its role, converting the sliding friction between the anti-throw net and the platform into rolling friction, so that the operator can easily extract the outermost anti-throw net, greatly reducing the extraction resistance.

[0037] 2) Netting transfer and installation: The extracted anti-throw netting is transferred to the workers in the suspended basket 1 through the work elevation platform 4. The workers install and fix the anti-throw netting. The workers on the platform operate the drive component again to move the left clamping plate 8 to the right to clamp the remaining anti-throw netting, ensuring that the netting remains stable before subsequent use. The above "loosening-extraction-transfer-installation-clamping" process is repeated until all anti-throw netting is installed.
