Description

Technical Field

[0001] This utility model belongs to the technical field of high-altitude operation construction platform, specifically a high-altitude operation auxiliary equipment platform. Background Technology

[0002] Stadiums are architectural venues used for sports competitions, physical exercise, or concerts. They also serve as performance centers for various performance activities. Given their large span, the roof structure plays a crucial role in the overall building design. Currently, the canopy structure erected above the stadium's seating area is prone to damage from long-term exposure to wind and sun, or may require maintenance and renovation to meet evolving architectural needs. These repairs and renovations necessitate high-altitude work by construction workers.

[0003] Due to the stadium's unique structure, the stands consist of tiered steps, making the construction of the platform and its ability to move quickly forward and backward crucial for high-altitude operations. Existing technologies typically employ scaffolding or aerial work platforms for high-altitude work due to space constraints. However, scaffolding can lead to insufficient load-bearing capacity at the track location and vulnerability to damage. Aerial work platforms, on the other hand, are inconvenient to operate due to the excessive distance between the lifting platform and the canopy. Furthermore, maintenance and renovation of the canopy often require the use of spider lifts, which need to operate continuously along the circular path of the steps. Therefore, designing an aerial work platform suitable for spider lifts is a pressing issue. Utility Model Content

[0004] To address the problems mentioned above in the background technology, this utility model provides an auxiliary equipment platform for high-altitude operations. By setting up a low platform, an intermediate platform, and a high platform on the steps, and at least the low platform is constructed using Bailey bridges and steel structure platforms, the structure is simple, easy to disassemble, and well adapted to the construction environment of steps.

[0005] The present invention adopts the following technical solution:

[0006] A high-altitude work auxiliary equipment platform is constructed on a stepped platform, comprising a low platform, an intermediate platform and a high platform arranged sequentially from low to high on the stepped platform, with the support surfaces of the low platform, intermediate platform and high platform located on the same horizontal plane.

[0007] The low platform includes at least one layer of low Bailey bridge in the vertical direction. A steel structure platform is set below the low Bailey bridge. The low Bailey bridge and the steel structure platform are detachably connected by U-shaped buckles. The steel structure platform is fixed on the step.

[0008] The elevated platform is formed by two I-beams supporting the steps or on a horizontal surface at the high point of the steps.

[0009] In some technical solutions, the low-level platform includes at least two layers of vertically fixed low-level Bailey bridges; the middle platform includes at least one layer of high-level Bailey bridges in the vertical direction, and a steel structure module is installed below the high-level Bailey bridges. The high-level Bailey bridges and the steel structure module are detachably connected by U-shaped buckles, and the steel structure module is fixed on the step.

[0010] In some technical solutions, a first hydraulic jack is installed on the side of the steel structure platform, and a second hydraulic jack is installed below the low-level Bailey bridge.

The piston rods of the first and second hydraulic jacks act on the lower end face of the low-level Bailey bridge.

[0012] The steel structure module is equipped with a third hydraulic jack, and a lifting air cushion is installed below the high-level Bailey bridge. The piston rod of the third hydraulic jack and the lifting air cushion act on the lower end face of the high-level Bailey bridge.

[0013] Furthermore, the lower end faces of the low-level Bailey bridge and the high-level Bailey bridge are provided with guide grooves extending in the front-to-back direction; when the low-level Bailey bridge and the high-level Bailey bridge need to be moved forward, pulleys adapted to the guide grooves are provided on the steps, steel structure platforms and steel structure modules.

[0014] Furthermore, the low-level Bailey bridge and the high-level Bailey bridge are fixedly connected by scissor bracing.

[0015] Furthermore, it also includes horizontal steel pipe connecting wall components, which are bolted to the side of the steps above the intermediate platform. The horizontal steel pipe connecting wall components are locked to the high-level Bailey bridge and the low-level Bailey bridge through vertical steel pipes and locking devices.

[0016] The outer side of the low platform is connected to the ground or steps using diagonal bracing.

[0017] Furthermore, steel plates are fixed to the upper surfaces of both the low-level and high-level Bailey bridges, and the upper surfaces of the steel plates form a support surface.

[0018] Furthermore, the U-shaped buckle includes a U-shaped connecting tube and an angle steel fitted on the U-shaped connecting tube. Both free ends of the U-shaped connecting tube are provided with external threads, which pass through the angle steel and are then screwed together by bolts.

[0019] Furthermore, the low-level platform, intermediate platform, and high-level platform are all made of steel.

Detailed Implementation

[0038] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is in conjunction with the appendix Figure 1 To be continued Figure 11 The present invention will be described in detail with specific embodiments.

[0040] like Figures 1 to 11 As shown, this application provides a high-altitude work auxiliary equipment platform. This platform is constructed on tiered steps and, once assembled, supports construction equipment such as spider cranes to facilitate high-altitude operations above the steps. The auxiliary equipment platform includes a low-level platform 1, a middle platform 2, and a high-level platform 3, arranged sequentially from low to high on the tiered steps. The support surfaces of the low-level platform 1, middle platform 2, and high-level platform 3 are located on the same horizontal plane and directly contact the construction equipment, providing support for it.

[0041] For ease of explanation, this application uses an auxiliary equipment platform for supporting a spider vehicle as an example for detailed description. The spider vehicle is existing technology and includes low-mounted outriggers 4, intermediate tracks 5, and high-mounted outriggers 6. The intermediate tracks 5 can drive the entire spider vehicle forward, while the low-mounted outriggers 4 and high-mounted outriggers 6 provide support for the spider vehicle. During high-altitude operations, the worker stands on the spider vehicle's platform, which is connected to the end of the telescopic boom. The telescopic boom of the spider vehicle then moves the worker to the work site.

[0042] In some embodiments, the low-level platform 1 includes at least one layer of low-level Bailey bridge 11 in the vertical direction. A steel structure platform 12 is provided below the low-level Bailey bridge 11. The low-level Bailey bridge 11 and the steel structure platform 12 are detachably connected by U-shaped buckles 7, and the steel structure platform 12 is fixed on the steps. The intermediate platform 2 is formed by combining the steel structure module 22 with the existing horizontal plane at the high position of the steps, and the high-level platform 3 is formed on the existing horizontal plane at the high position of the steps. Obviously, the above-mentioned auxiliary equipment platform is suitable for high-altitude operations above the high position of the steps. In this case, only the low-level platform 1 needs to be built with the low-level Bailey bridge 11, while the intermediate platform 1 and the high-level platform 3 can utilize the existing horizontal plane at the high position of the steps. Therefore, fewer components are required to build the platform, and the construction process is time-saving and labor-saving. Of course, when the high-altitude operation is located above the middle of the steps, the equipment platform in this embodiment is no longer applicable.

[0043] It is known that high-altitude operations above the tiered steps of stadiums or other venues are usually extensive. Before construction, the extensive high-altitude operations need to be divided into multiple construction positions along the length of the tiered steps. The corresponding high-altitude operations are completed at each construction position, and each construction position requires an equipment platform. In order to achieve platform reuse, this application detachably connects the low-position Bailey bridge 11 and the steel structure platform 12 through a U-shaped buckle 7. The U-shaped buckle 7 includes a U-shaped connecting pipe 71 and an angle steel 72 fitted on the U-shaped connecting pipe 71. Both free ends of the U-shaped connecting pipe 71 are provided with external threads. After the external threads pass through the angle steel 72, they are bolted together. That is, the lower end of the low-position Bailey bridge 11 and the upper end of the steel structure platform 12 are both fitted into the U-shaped connecting pipe 71, and then the angle steel 72 is inserted into the two free ends. Finally, it is tightened with bolts. The above-mentioned connection method enables the rapid disassembly of the low-position Bailey bridge 11. After disassembly, it can be quickly moved to the next construction position, realizing the reuse of the platform. At the same time, the connection method of U-shaped buckle 7 can reduce the platform construction time and shorten the construction cycle.

[0044] In other embodiments, see Figure 1 and Figure 3 The low-level platform 1 includes at least two layers of vertically fixed low-level Bailey bridges 11; the middle platform 2 includes at least one layer of high-level Bailey bridges 21, with steel structure modules 22 installed below the high-level Bailey bridges 21. The high-level Bailey bridges 21 and the steel structure modules 22 are detachably connected by U-shaped buckles 7. The steel structure modules 22 are fixed on the steps. The high-level platform 3 is formed by two I-beams supporting the steps. The above-mentioned equipment platform is suitable for high-altitude operations above the middle position of the steps. In this case, both the low-level platform 1 and the middle platform 2 require Bailey bridges for construction, and the number of components required for construction is relatively large, making the construction process relatively complex. It is worth noting that the low-level Bailey bridges 11 and the high-level Bailey bridges 21 in this embodiment can be Bailey bridges of the same structure. Here, for ease of matching with the low-level platform 1 and the middle platform 2, they are defined as low-level Bailey bridges 11 and high-level Bailey bridges 21, respectively.

[0045] It should be further explained that both the steel structure module 22 used to build the intermediate platform 2 and the steel structure platform 12 used to build the low-level platform 1 are custom-made steel modules. Since the intermediate platform 2 bears the main weight of the spider vehicle, the steel structure module 22 requires high strength and rigidity. In this embodiment, the steel structure module 22 is a rectangular structure, including a supporting beam 221 and supporting legs 222 evenly distributed below the supporting beam 221. The supporting beam 221 provides a certain supporting area, and the supporting legs 222 evenly support the supporting beam 221. For example, the steel structure module 22 in this embodiment can be formed by welding square tubing. The low-level Bailey bridge 11 is used to support the low-level support legs 3 of the spider vehicle, and its load-bearing capacity requirement is not high. The steel structure platform 12 is used to support the low-level Bailey bridge 11; therefore, the strength requirement for the steel structure platform 12 is less than that for the steel structure module 22. For example, the steel structure platform 12 can be formed by welding I-beams, but it is not limited to this.

[0046] In some embodiments, when only the lower platform 1 requires Bailey bridge construction, and the middle platform 2 and the upper platform 3 are constructed using existing horizontal surfaces via steps, a first hydraulic jack 121 is provided on the side of the steel structure platform 12 to enable movement of the lower Bailey bridge 11. A second hydraulic jack 122 is also provided below the lower Bailey bridge 11. The piston rods of the first hydraulic jack 121 and the second hydraulic jack 122 act on the lower end face of the lower Bailey bridge 11. In addition, the lower end face of the lower Bailey bridge 11 is also provided with a section extending in the front-rear direction. Guide chute 111; After completing the high-altitude operation at the designated position, control the spider crane to lift the low-position outrigger 4, then disconnect the U-shaped buckle 7 between the low-position Bailey bridge 11 and the steel structure platform 12, start the first hydraulic jack 121 and the second hydraulic jack 122, and slowly lift the low-position Bailey bridge 11 upwards. After the low-position Bailey bridge 11 is lifted a certain distance, install pulleys 112 that are compatible with the guide chute 111 on the steel structure platform 12 and steps below it. The low-position Bailey bridge 11 can then be pulled forward to the next construction position with the help of the pulleys 112 using a winch.

[0047] In some embodiments, see Figure 5 and Figure 9When the low-level platform 1 requires the construction of a low-level Bailey bridge 11 and the middle platform requires the construction of a high-level Bailey bridge 21, a first hydraulic jack 121 is installed on the side of the steel structure platform 12, and a second hydraulic jack 122 is installed below the low-level Bailey bridge 11. The piston rods of the first hydraulic jack 121 and the second hydraulic jack 122 work together on the lower end face of the low-level Bailey bridge 11 to slowly lift the low-level Bailey bridge 11 upwards. A third hydraulic jack 223 is installed inside the steel structure module 22, and a lifting air cushion 224 is installed below the high-level Bailey bridge 21. The piston rod of the third hydraulic jack 223 and the lifting air cushion 224 work together on the lower end face of the high-level Bailey bridge 21 to slowly lift the high-level Bailey bridge 21 upwards. To enable the forward movement of the lower Bailey bridge 11 and the upper Bailey bridge 21, the lower end faces of both the lower Bailey bridge 11 and the upper Bailey bridge 21 are provided with guide grooves 111 extending in the front-back direction. When it is necessary to move the lower Bailey bridge 11 and the upper Bailey bridge 21 forward, the lower Bailey bridge 11 and the upper Bailey bridge 21 are first lifted upward, and then pulleys 112 adapted to the guide grooves 111 are provided on the steps, the steel structure platform 12 and the steel structure module 22.

[0048] It should be noted that tiered steps usually have a certain length. When performing high-altitude operations on tiered steps of a certain length, multiple preset positions need to be set in advance along the length of the steps. The spider truck can then work at each of the preset positions to complete all the high-altitude operations above the tiered steps.

[0049] See Figures 1 to 11 In this embodiment of the application, taking the example that both the low-level platform 1 and the intermediate platform 2 require Bailey bridge construction, the steps for performing high-altitude operations using the equipment platform and spider crane in this embodiment are as follows:

[0050] S1. On the steps at the first preset position, a low platform 1, a middle platform 2, and a high platform 3 are erected sequentially from low to high. There needs to be a certain distance between the low platform 1, the middle platform 2, and the high platform 3, and the support surfaces of the low platform 1, the middle platform 2, and the high platform 3 are flush. The support surfaces are used to support the low outriggers 4, the middle tracks 5, and the high outriggers 6 of the spider vehicle. In this application, the low platform 1, the middle platform 2, and the high platform 3 are erected on different steps. The specific number of steps between them can be designed according to the actual construction scenario.

[0051] Specifically, the construction method of the low-level platform 1 is as follows: two layers of low-level Bailey bridge 11 are set in the vertical direction and fixedly connected to each other. The low-level Bailey bridge 11 in the width direction is fixedly connected with a flower rack to form an integrated low-level Bailey bridge 11. Part of the integrated low-level Bailey bridge 11 is located on the steps, and the other part is suspended. A steel structure platform 12 is fixed on the steps below the suspended part. The steel structure platform 12 includes a vertical support part 123 and a horizontal support part 124. The vertical support part 123 is fixed on the steps below the suspended part, and the horizontal support part 124 is located on the steps where the low-level Bailey bridge 11 is located. The low-level Bailey bridge 11 is attached to the horizontal support part 124. The bottom of the low-level Bailey bridge 11 is bolted to the steel structure platform 12 using U-shaped buckles 7 so that the steel structure platform 12 supports the low-level Bailey bridge 11. A steel plate is erected on the upper end of the low-level Bailey bridge 11 to form a support surface.

[0052] The construction method of the intermediate platform is as follows: a high-level Bailey bridge 21 is built. The high-level Bailey bridges in the width direction are fixedly connected with flower racks to form an integrated high-level Bailey bridge 21. Part of the high-level Bailey bridge 21 is located on the steps, and the other part is suspended. A steel structure module 22 is fixed on the steps below the suspended part. The bottom of the high-level Bailey bridge 21 and the steel structure module 22 are bolted together using U-shaped buckles 7 so that the steel structure module 22 supports the high-level Bailey bridge 21. A steel plate is erected on the upper end of the high-level Bailey bridge 21 to form a support surface.

[0053] S2. Use a truck crane to lift the spider truck, ensuring that the lower outriggers 4 are positioned on the lower platform 1, the intermediate track 5 is supported on the intermediate platform 2, and the upper outriggers 6 are positioned on the upper platform 3. The lower outriggers 4 and 6 are positioned by attaching rubber pads to their bottoms with glue and then bonding them to the supporting surface. Angle steel is then welded to the edges of the lower outriggers 4 and 6 to provide positioning. Since the intermediate track 5 bears the main weight of the spider truck and the spider truck moves by relying on the intermediate track 5, no positioning is required at the intermediate track 5.

[0054] S3. The spider truck performs high-altitude operations at the first preset position until the high-altitude operations at the first preset position are completed. This application does not describe in detail how the spider truck performs high-altitude operations. The platform position on the spider truck can be moved according to the actual situation.

[0055] S4. Release the limit of the low-position support leg 4 on the low-position platform 1 and the limit of the high-position support leg 6 on the high-position platform 3. Operate the spider car to lift the low-position support leg 4 and the high-position support leg 6 upward, so that the low-position support leg 4 leaves the low-position platform 1 and the high-position support leg 6 leaves the high-position platform 3.

[0056] S5. Remove the low-level platform 1 and use a winch to move the low-level platform 1 forward on the same step to the second preset position; in this application, the front-back direction of the step is the length direction of the step.

[0057] Specifically, the method for dismantling the lower platform 1 and moving it forward is as follows:

[0058] S501. Remove the U-shaped buckle 7 and corresponding bolts between the low-position Bailey bridge 11 and the steel structure platform 12 to release the limiting position between the low-position Bailey bridge 11 and the steel structure platform 12. At the same time, start the first hydraulic jack 121 and the second hydraulic jack 122. The piston rods of the first hydraulic jack 121 and the second hydraulic jack 122 work together to slowly lift the low-position Bailey bridge 11 upward.

[0059] S502. Install pulleys 112 on the steps or steel structure platform 12 so that the pulleys 112 correspond to the guide grooves 111 at the lower end of the low Bailey frame 11. Control the first hydraulic jack 121 and the third hydraulic jack 122 to slowly descend so that the pulleys 112 are located in the guide grooves 111.

[0060] S503. Use a winch to slide the low-position Bailey bridge 11 forward a certain distance. It is worth noting that in this embodiment, the low-position Bailey bridge 11 and the high-position Bailey bridge 21 are usually arranged in multiple rows in the front-to-back direction. That is, multiple steel structure platforms 12 are arranged at intervals below the low-position Bailey bridge 11. By using a winch to slide forward a certain distance, at least one of the last steel structure platforms 12 can be detached from the low-position Bailey bridge 11, so that the steel structure platform 12 can be detached.

[0061] S504. After the low-position Bailey bridge 11 slides a certain distance, the steel platform structure 12 and the corresponding pulley 112 behind it are removed and replaced in front until the low-position Bailey bridge 11 and the steel structure platform 12 move to the second preset position.

[0062] S505. Remove pulley 112, and use first hydraulic jack 121 and second hydraulic jack 122 to lower the low-position Bailey bridge 11 to the initial position. Then, reconnect the low-position Bailey bridge 11 and the steel structure platform 12, so that the low-position platform 1 can be reused.

[0063] S6. Lay a steel plate on the middle platform 2 in front of the spider car, and operate the spider car to move forward a certain distance. This distance must ensure that the low-position outrigger 4 can be stably limited to the low-position platform 1 at the second preset position when it is lowered.

[0064] S7. Remove the high platform 3 and move it forward on the same step to the second preset position so that the positions of the high platform 3 and the low platform 1 correspond. Since the high platform 3 is formed by two I-beams, the process of moving the high platform is relatively simple. Just release the I-beams from the steps to move it forward and realize the reuse of the high platform 3.

[0065] S8. Operate the spider vehicle to restrict the low-position outrigger 4 to the low-position platform 1 again, and restrict the high-position outrigger 6 to the high-position platform 3 again. After the restriction is completed, the spider vehicle is suspended in the air by the high-position outrigger 4 and the low-position outrigger 6, so that the middle track 5 is separated from the middle platform 2.

[0066] S9. Remove the intermediate platform 2, and use a winch to move the intermediate platform 2 forward to the second preset position. Then, lower the intermediate track 5 of the spider truck onto the intermediate platform 2. The spider truck will then perform high-altitude operations at the second preset position until the high-altitude operations at the second preset position are completed.

[0067] Specifically, the method for dismantling the intermediate platform is as follows:

[0068] S901. Remove the U-shaped buckle 7 and corresponding bolts between the high-level Bailey bridge 21 and the steel structure module 22. Fix the steel plate at the bottom of the high-level Bailey bridge 21 so that the high-level Bailey bridge 21 can move relative to the steel structure module 22. At the same time, start the third hydraulic jack 223 and the lifting air cushion 224. The third hydraulic jack 223 and the lifting air cushion 224 lift the steel plate to slowly lift the Bailey bridge 21 upwards from the high position.

[0069] S902. Install pulleys 112 on the steps or steel structure module 22 so that pulleys 112 correspond to the guide groove 111 at the lower end of the high-level Bailey bridge 21. Control the third hydraulic jack 223 and lifting air cushion 224 to slowly descend so that pulleys 112 are located in the guide groove 111.

[0070] S903. Use a winch to slide the high-level Bailey bridge 21 forward a certain distance. It is worth noting that the high-level Bailey bridge 21 is usually arranged in multiple rows in the front-to-back direction. That is, multiple steel structure modules 22 are arranged at intervals below the high-level Bailey bridge 21. By using a winch to slide forward a certain distance, at least one of the last steel structure modules 22 can be detached from the high-level Bailey bridge 21, so that the steel structure module 22 can be disassembled.

[0071] S904. After the high-position Bailey bridge 21 slides a certain distance, the steel platform module 22 and the corresponding pulley 112 behind it are removed and replaced in front until the high-position Bailey bridge 21 moves to the second preset position.

[0072] S905, Remove pulley 112, use third hydraulic jack 223 and lifting air cushion 224 to lower the high-level Bailey bridge 21 to the initial position, and then fix the high-level Bailey bridge 21 and steel structure module 22 again, thereby realizing the reuse of the intermediate platform 2.

[0073] S10. Repeat steps S4-S9 to complete the high-altitude operations at all preset locations.

[0074] By using the equipment platform of this application in conjunction with the spider truck for high-altitude operations, the platform can be reused repeatedly, improving the platform's turnover rate. Furthermore, the cooperation of the guide chute 111 and pulley 112 makes it easier to move and set up the platform, shortening the construction cycle.

[0075] In this application, U-shaped buckles 7 and bolts are used to connect the low-level Bailey bridge 11 and the steel structure platform 12, as well as the high-level Bailey bridge 21 and the steel structure module 22. The connection is reliable, and the Bailey bridge assembly process is rapid, enabling construction to be completed in a short time, greatly shortening the construction cycle. It can also be easily disassembled, facilitating transportation, reuse, and resale. The overall structure is simple, reducing usage costs. Furthermore, the Bailey bridge of this application can be adjusted according to construction needs, allowing it to adapt to buildings of different heights and angles, flexibly responding to construction environments and requirements.

[0076] In some embodiments, see Figure 1 and Figure 2 The low-level Bailey bridge 11 and the high-level Bailey bridge 21 are fixedly connected by scissor braces 81 to ensure the stability of the low-level platform 1 and the middle platform 2. Of course, when moving the platforms, the scissor braces 81 must first be disassembled before they can be moved.

[0077] In some embodiments, see Figure 1 and Figure 2 Due to the significant weight of the spider vehicle, the platform requires more robust support. Therefore, it also includes horizontal steel pipe connecting wall components 82. These components are bolted to the side of the steps higher than the intermediate platform 2. The horizontal steel pipe connecting wall components 82 are locked to the high-level Bailey bridge 21 and the low-level Bailey bridge 11 via vertical steel pipes 83 and locking fasteners. The outer side of the low-level platform 1 is connected to the ground or steps using diagonal braces 84. To further ensure the stability of the equipment platform, the angle between the diagonal braces 84 and the ground is no greater than 60°. Of course, when moving the platform, the above structures must be disassembled before the movement.

[0078] Furthermore, steel plates are fixed to the upper surfaces of both the low-position Bailey bridge 11 and the high-position Bailey bridge 21, and the upper surfaces of the steel plates form a support surface.

[0079] For details, please refer to Figure 11 The U-shaped buckle 7 in this embodiment includes a U-shaped connecting tube 71 and an angle steel 72 fitted on the U-shaped connecting tube 71. Both free ends of the U-shaped connecting tube 71 are provided with external threads. The external threads pass through the angle steel 71 and are then screwed together by bolts. The connection process of the U-shaped buckle 7 does not require welding or other complicated operations. It is only necessary to fit the two connected parts into the U-shaped connecting tube 71, and then tighten the bolts after the angle steel 72 passes through the two free ends. The structure is simple and easy to operate.

[0080] In some embodiments, the low-level platform 1, the middle platform 2, and the high-level platform 3 are all made of steel, which has high strength, rigidity, and seismic resistance, and can withstand a large load, thus ensuring the stability and safety of the equipment.

[0081] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
