Description

Technical Field

[0001] The invention belongs to the technical field of aerial work construction, and specifically relates to a construction method of an aerial work auxiliary equipment platform. Background Art

[0002] Stadiums are places for sports competitions, physical training or concerts. Stadiums are also used as performing arts centers for various performances. Stadiums have a large span, so the roof structure occupies an important position in the entire building. At present, the canopy structure built above the audience seats of the stadium is prone to damage during long-term wind and sun exposure, or the canopy structure needs to be repaired and renovated due to the staged demand for architectural shape, and the workers need to perform high-altitude operations during the repair and renovation process.

[0003] Due to the limited space of the stadium, if scaffolding is used for high-altitude operations, the runway will have insufficient bearing capacity and be easily damaged; if a high-altitude vehicle is used, the lifting platform is too far away from the stand canopy, making it inconvenient to operate. In addition, spider vehicles are usually used for maintenance and renovation of canopies. The spider vehicle needs to work continuously along the circular direction of the steps. The platform construction method and the construction method for quickly moving the spider vehicle are particularly important. Summary of the invention

DETAILED DESCRIPTION

[0062] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0063] The following is combined with Figure 1 To Attachment Fig.12 The present invention is described in detail with reference to specific embodiments.

[0064] See also Figures 1 to 12 The present invention provides a construction method for an aerial work auxiliary equipment platform, which uses a spider car to perform aerial work on a step, and the spider car used includes a low-position leg 4, an intermediate crawler 5 and a high-position leg 6; the step in the present application has a certain length, and it is necessary to set a plurality of preset positions in the length direction of the step in advance, and the spider car can complete the aerial work above the step by constructing at the preset positions respectively; the construction method of the present application includes the following steps:

[0065] S1. On the steps at the first preset position, a low platform 1, an intermediate platform 2 and a high platform 3 are sequentially built from low to high. A certain distance is required between the low platform 1, the intermediate platform 2 and the high platform 3, and the supporting surfaces of the low platform 1, the intermediate platform 2 and the high platform 3 are flush. The supporting surfaces are used to support the low legs 4, the intermediate crawler 5 and the high legs 6 of the spider car. The low platform 1, the intermediate platform 2 and the high platform 3 of the present application are respectively built on different steps, and the specific difference in the number of steps can be designed according to the actual construction scene.

[0066] S2. Use a car crane to hoist the spider car, so that the low legs 4 of the spider car are limited on the low platform 1, the middle crawler 5 is supported on the middle platform 2, and the high legs 6 are limited on the high platform 3. The low legs 4 and the high legs 6 are limited by gluing rubber gaskets on their bottoms and then bonding them to the supporting surface, and then using angle steel to weld and limit the edges of the low legs 4 and the high legs 6; since the middle crawler 5 carries the main weight of the spider car, the spider car relies on the middle crawler 5 to achieve movement, so the middle crawler 5 does not need to be limited;

[0067] S3, the spider car 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 specifically describe how the spider car performs high-altitude operations. The platform position on the spider car can be controlled to move according to actual conditions;

[0068] S4, releasing the limit of the low outrigger 4 on the low platform 1 and the limit of the high outrigger 6 on the high platform 3, and operating the spider car to lift the low outrigger 4 and the high outrigger 6 upwards, so that the low outrigger 4 leaves the low platform 1, and the high outrigger 6 leaves the high platform 3;

[0069] S5, dismantle the low platform 1, and use a winch to move the low platform 1 forward to a second preset position on the same step; the front-to-back direction of the step in this application is the length direction of the step;

[0070] S6. Lay a steel plate on the middle platform 2 in front of the spider car, and operate the spider car to move forward for a distance that is required to ensure that the low-position legs 4 can be stably limited on the low-position platform 1 at the second preset position when lowered;

[0071] S7. Remove the high-level platform and push it forward to the second preset position on the same step so that the positions of the high-level platform and the low-level platform correspond to each other. Since the high-level platform is formed by two I-beams, the process of moving the high-level platform is relatively simple. It only requires releasing the I-beam from the step to move it forward, thereby realizing the reuse of the high-level platform.

[0072] S8, operate the spider car so that the low outriggers are restricted on the low platform again, and the high outriggers are restricted on the high platform again. After the restriction is completed, the spider car is suspended in the air by the high outriggers and the low outriggers, so that the middle crawler is separated from the middle platform;

[0073] S9, after removing the middle platform 2 and using a winch to move the middle platform 2 forward to the second preset position, lower the middle crawler 5 of the spider car onto the middle platform 2, and the spider car performs the aerial work at the second preset position until the aerial work at the second preset position is completed;

[0074] S10. Repeat steps S4-S9 to complete the aerial work at all preset positions.

[0075] It should be noted that in the present application, the high platform 3 is generally selected on the top step of the ladder steps, using the existing horizontal surface of the top step. The horizontal surface is relatively wide, and less material can be used to build the platform, saving construction materials and construction time.

[0076] Due to the special construction conditions and limited site, this application is not suitable for the use of scaffolding construction methods and lifting platform construction methods; however, the low platform 1, the middle platform 2, the high platform 3 and the spider car are cleverly coordinated to achieve the recycling of the platform, improve the turnover rate of materials, and at the same time reduce the construction time of the equipment platform and shorten the construction period.

[0077] For further information, see Figures 5 to 8 , in step S1, before construction, it is necessary to customize the steel structure platform 12, steel structure module 22, Bailey frame, U-shaped buckle 7 and other construction components according to the construction site;

[0078] The low-level platform 1 includes at least two layers of low-level Bailey frames 11 spliced ​​in sequence from top to bottom, and the bottoms of at least two layers of low-level Bailey frames 11 are detachably fixedly connected to the steel structure platform 12 through U-shaped buckles 7, and the steel structure platform 12 is fixed on the steps; in a specific embodiment, the construction method of the low-level platform 1 is as follows: two layers of low-level Bailey frames 11 are arranged in the up and down directions, the two layers of low-level Bailey frames 11 are fixedly connected, and the Bailey frames in the width direction are fixedly connected using flower racks to form an integrated low-level Bailey frame 11, a part of the integrated low-level Bailey frame 11 is located on the steps, and the other part The steel structure platform 12 is fixed on the step below the suspended part, and 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 step below the suspended part, and the horizontal support part 124 is located on the step where the low-level Bailey frame 11 is located. The low-level Bailey frame 11 is overlapped on the horizontal support part 124, and the bottom of the low-level Bailey frame 11 is bolted to the steel structure platform 12 using a U-shaped buckle 7, so that the steel structure platform 12 supports the low-level Bailey frame 11, and a steel plate is set on the upper end of the low-level Bailey frame 11 to form a supporting surface.

[0079] See also Figures 9 to 12The intermediate platform 2 includes at least one layer of high-position Bailey frame 21, and the bottom of at least one layer of high-position Bailey frame 21 is detachably fixedly connected to the steel structure module 22 through a U-shaped buckle 7, and the steel structure module 22 is fixed on the step; in a specific embodiment, the construction method of the intermediate platform 2 is: build a layer of high-position Bailey frame 21, and the high-position Bailey frames in the width direction are fixedly connected using a flower rack to form an integrated high-position Bailey frame 21, a part of the high-position Bailey frame 21 is located on the step, and the other part is suspended, and the steel structure module 22 is fixed on the step below the suspended part, and the U-shaped buckle 7 is used to tighten the bottom of the high-position Bailey frame 21 and the steel structure module 22 with bolts, so that the steel structure module 22 supports the high-position Bailey frame 21, and a steel plate is set up on the upper end of the high-position Bailey frame 21 to form a supporting surface.

[0080] It should be further explained that the steel structure module 22 used to build the intermediate platform 2 and the steel structure platform 12 used to build the low platform 1 are both customized steel modules. Since the intermediate platform 2 is used to bear the main weight of the spider car, the strength and rigidity requirements of the steel structure module 22 are relatively high. The steel structure module 22 in this embodiment is a rectangular structure, including a support beam 221 and support legs 222 evenly distributed below the support beam 221. The support beam 221 provides a certain support area, and the support legs 222 evenly provide support for the support beam 221; for example, the steel structure module 22 in this embodiment can be formed by welding square tubes. The low-level Bailey frame 11 is used to bear the low-level legs 4 of the spider car, and its bearing capacity is not required to be high. The steel structure platform 12 is used to bear the low-level Bailey frame 11, so the strength requirement of the steel structure platform 12 is less than the strength requirement of the steel structure module 22; for example, the steel structure platform 12 can be formed by welding I-beams, but is not limited to this. In addition, the low Bailey frame 11 and the high Bailey frame 12 in this embodiment can be selected as Bailey frames of the same structure. In order to facilitate matching with the low platform 1 and the high platform 3, they are defined as the low Bailey frame 11 and the high Bailey frame 12 respectively.

[0081] The high platform 3 is formed by two I-beams supported on the steps, and steel plates are laid on the upper ends of the two I-beams to form a supporting surface.

[0082] The present application utilizes U-shaped buckles 7 and bolts to realize the connection between the low-position Bailey frame 11 and the steel structure platform 12, and the high-position Bailey frame 21 and the steel structure module 22. The connection is reliable, and the assembly process of the Bailey frame is fast. The construction can be completed in a short time, which greatly shortens the construction period. The Bailey frame can be easily disassembled, which is convenient for transportation, reuse and transportation. The overall structure is simple, which reduces the cost of use. At the same time, the Bailey frame of the present application can be adjusted according to the construction adjustment, so that it can adapt to buildings of different heights and angles, and can flexibly respond to the construction environment and needs.

[0083] For further information, see Figure 2 , Figure 4 The low-level Bailey frame 11 of the low-level platform 1 and the high-level Bailey frame 21 of the middle platform 2 are fixedly connected by a scissors brace 81 to ensure the stability of the low-level platform 1 and the middle platform 2. Of course, when moving the platform, the scissors brace 81 must be removed first to achieve their respective movements; at the same time, in the horizontal direction, the wall member 82 is connected by a horizontal steel pipe and anchored on the side of the step with bolts. The horizontal steel pipe connecting wall member 82 is locked with the high-level Bailey frame 21 and the low-level Bailey frame 11 by a vertical steel pipe 83 and a locking member; an oblique brace 84 is used on the outside of the low-level platform 1 to connect to the ground or the step. In order to further ensure the stability of the equipment platform, the angle between the oblique brace 84 and the ground is not greater than 60°. Of course, when moving the platform, the above structure also needs to be disassembled before moving.

[0084] For further information, see Figure 6 and Fig.10 The lower end surfaces of the low-position Bailey frame 11 and the high-position Bailey frame 21 are provided with two parallel guide grooves 111 extending in the front-to-back direction. The guide grooves 111 serve as guide rails to provide guidance for the forward movement of the low-position Bailey frame 11 and the high-position Bailey frame 21 during the construction process.

[0085] Furthermore, the steel structure platform 12 and the steel structure module 22 are both vertical load-bearing rods, and the widths of the high-level Bailey frame 21 and the low-level Bailey frame 11 are both greater than the width of the steps; the steel structure platform 12 is fixed to the step below the step where the low-level Bailey frame 11 is located, and the steel structure module 22 is fixed to the step below the step where the high-level Bailey frame 21 is located, ensuring that the low-level Bailey frame 11 and the high-level Bailey frame 21 have a certain width to support the spider car.

[0086] For further information, see Figure 6 A first hydraulic jack 121 is provided on one side of the steel structure platform 12, and a second hydraulic jack 223 is provided on the steel structure module 22. The piston rod of the first hydraulic jack 121 acts on the low-position Bailey frame 11, and the piston rod of the second hydraulic jack 223 acts on the high-position Bailey frame 21;

[0087] See also Fig.10 A first steel plate is fixed at the bottom of the low-position Bailey frame 11, and a third hydraulic jack 122 and a first hydraulic jack 121 are arranged at intervals below the first steel plate. The first hydraulic jack 121 and the third hydraulic jack 122 can lift the low-position Bailey frame 11 upward by acting simultaneously; the third hydraulic jack 122 can be fixed on the step, and cooperate with the first hydraulic jack 121 to lift the low-position Bailey frame 11 upward steadily;

[0088] A lifting air cushion 224 is also provided at the bottom of the high-position Bailey frame 21 , and the second hydraulic jack 223 and the lifting air cushion 224 can lift the high-position Bailey frame 21 upwards by acting simultaneously.

[0089] The purpose of setting up the first hydraulic jack 121, the second hydraulic jack 223, the third hydraulic jack 122 and the lifting cushion 224 in the present application is to facilitate lifting the low-level Bailey frame 11 and the high-level Bailey frame 21 upward during the construction process, and installing a pulley 112 thereunder to cooperate with the guide slide groove 111 at the bottom of the low-level Bailey frame 11 and the high-level Bailey frame 21 to realize the movement of the platform.

[0090] Furthermore, in step S5, the method for dismantling the low platform 1 is:

[0091] S501, remove the U-shaped buckle 7 and the corresponding bolts between the low-position Bailey frame 11 and the steel structure platform 12, so that the low-position Bailey frame 11 can move relative to the steel structure platform 12, and start the first hydraulic jack 121 and the third hydraulic jack 122 at the same time, and the piston rod of the first hydraulic jack 121 and the piston rod of the third hydraulic jack 122 jointly lift the first steel plate to slowly lift the low-position Bailey frame 11;

[0092] S502, installing a pulley 112 on the step or the steel structure platform 12, so that the pulley 112 corresponds to the guide slot 111 at the lower end of the low-position Bailey frame 11, and controlling the first hydraulic jack 121 and the third hydraulic jack 122 to slowly descend so that the pulley 112 is located in the guide slot 111;

[0093] S503, use a winch to slide the low-level Bailey frame 11 forward for a distance; it is worth noting that the low-level Bailey frame 11 and the high-level Bailey frame 21 in this embodiment 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-level Bailey frame 11. By using the winch to slide forward for a distance, at least one of the rearmost steel structure platforms 12 can be separated from the low-level Bailey frame 11, so that the steel structure platform 12 can be detached.

[0094] S504, after the low-position Bailey frame 11 slides for a certain distance, the steel platform structure 12 and the corresponding pulley 112 are removed from the rear, and replaced in the front, until the low-position Bailey frame 11 moves to the second preset position;

[0095] S505, remove the pulley 12, use the first hydraulic jack 121 and the third hydraulic jack 122 to lower the low-level Bailey frame 11 to the initial position, and then re-fix the low-level Bailey frame 11 and the steel structure platform 12 to make the low-level platform 1 reusable.

[0096] Furthermore, in step S9, the method for removing the intermediate platform 2 is:

[0097] S901, remove the U-shaped buckle 7 and the corresponding bolts between the high-position Bailey frame 21 and the steel structure module 22, fix the second steel plate at the bottom of the high-position Bailey frame 21, so that the high-position Bailey frame 21 can move relative to the steel structure module 22, and start the second hydraulic jack 223 and the lifting air cushion 224 at the same time. The second hydraulic jack 223 and the lifting air cushion 224 lift the second steel plate to slowly lift the Bailey frame 21 at a high position;

[0098] S902, install the pulley 112 on the step or the steel structure module 22, so that the pulley 112 corresponds to the guide slot 112 at the lower end of the high-position Bailey frame 21, and control the second hydraulic jack 223 and the lifting air cushion 224 to slowly descend so that the pulley 112 is located in the guide slot 111;

[0099] S903. Use a winch to slide the high-position Bailey frame 21 forward for a certain distance. It is worth noting that the high-position Bailey frame 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-position Bailey frame 21. By using the winch to slide forward for a certain distance, at least one of the rearmost steel structure modules 22 can be separated from the high-position Bailey frame 21, so that the steel structure module 22 can be detached.

[0100] S904, after the high-position Bailey frame 21 slides for a certain distance, the steel platform module 22 and the corresponding pulley 112 are removed from the rear, and replaced in the front, until the high-position Bailey frame 21 moves to the second preset position;

[0101] S905, remove the pulley 112, use the second hydraulic jack 223 and the lifting air cushion 224 to lower the high-position Bailey frame 21 to the initial position, and then fix the high-position Bailey frame 21 and the steel structure module 22 again, so as to realize the reuse of the intermediate platform 2.

[0102] Furthermore, the low platform 1, the middle platform 2 and the high platform 3 are all made of steel, have high strength, rigidity and shock resistance, can withstand a large amount of load, and ensure the stability and safety of the equipment.

[0103] Furthermore, rubber gaskets are glued to the bottom of the low leg 4 and the high leg 6, and are in contact with the supporting surfaces of the low platform 1 and the high platform 3 through the rubber gaskets, and the bottom edges of the low leg 4 and the high leg 6 are welded and limited using angle steel.

[0104] For details, see Fig.12The U-shaped buckle 7 in the embodiment of the present application includes a U-shaped connecting tube 71 and an angle steel 72 sleeved on the U-shaped connecting tube 71. Both free ends of the U-shaped connecting tube 71 are provided with external threads, which pass through the angle steel 72 and are screwed together with bolts. During the connection process of the U-shaped buckle 7, no welding or other complicated operations are required. Only the two connected parts need to be sleeved in the U-shaped connecting tube 71, and then the angle steel 72 is passed through the two free ends and the bolts are tightened. The structure is simple and easy to operate.

[0105] In the present application, U-shaped buckles 7 and bolts are used to realize the connection between the low-position Bailey frame 11 and the steel structure platform 12, and the high-position Bailey frame 21 and the steel structure module 22. The connection is reliable, and the assembly process of the Bailey frame is fast. It can be built in a short time, greatly shortening the construction period, and can be easily disassembled, convenient for transportation, reuse and transportation. The overall structure is simple, reducing the cost of use. At the same time, the Bailey frame of the present application can be adjusted according to the construction adjustment, so that it can adapt to buildings of different heights and angles, and can flexibly respond to construction environments and needs.
