Abstract
Description
Technical Field
[0001] This application relates to the field of building formwork support system technology, and in particular to a tall formwork support system for a large-span arch structure. Background Technology
[0002] Large-span arched structures are commonly used in bridges, tunnels, roofs, and concrete canopies. These structures feature circular curves and are widely adopted due to their durability, low maintenance costs, and simple construction. Steel formwork is typically used for support during the construction of arched structures.
[0003] In related technologies, the high-formwork support system for large-span arched structures mainly includes an arc-shaped steel body and scaffolding. The arc-shaped steel body comprises multiple arc-shaped main bodies and support seats set on the inner wall of the arc-shaped main bodies. The scaffolding has multiple support positions for supporting the support seats. Multiple arc-shaped main bodies are connected end-to-end to form the arc-shaped steel body. The arc-shaped main bodies are arc-shaped structures, and all arc-shaped main bodies have the same curvature. Connecting plates are set at both ends of the arc-shaped main bodies along their length. Through holes are set on the connecting plates. Fastening bolts pass through the through holes on the connecting plates of two adjacent arc-shaped main bodies and are fixedly connected by fastening nuts, thereby fixing two adjacent arc-shaped main bodies together. The scaffolding supports the arc-shaped steel body, and the arc-shaped steel body supports the arched structure.
[0004] Regarding the aforementioned technologies, at the construction site, after the arc-shaped main body is assembled into an arc-shaped steel body, in order to facilitate demolding and reduce the impact on the integrity of the concrete arch structure, it is usually necessary to manually apply oil to the outside of the arc-shaped steel body. Due to the large span of the arc-shaped steel body, the labor intensity of workers is relatively high. Summary of the Invention
[0005] To reduce the labor intensity of workers to a certain extent, this application provides a tall formwork support system for a large-span arched structure.
[0006] The technical solution for a tall formwork support system for a large-span arched structure provided in this application is as follows: A large-span arched high-formwork support system includes multiple interconnected arc-shaped main bodies. An oil storage tank is located on one side of each arc-shaped main body, with the oil storage tank having the same curvature as the arc-shaped main body. The outer wall of the oil storage tank is higher than the outer wall of the arc-shaped main body. Multiple oil outlets are provided on the side of the oil storage tank closest to the outer wall of the arc-shaped main body. An opening and closing plate is slidably installed inside the oil storage tank, with opening and closing holes corresponding to the oil outlets. An adjustment component is provided on the oil storage tank to adjust the opening and closing plate, causing the opening and closing holes to slide towards or away from the oil outlets. A guide rail is provided on the side of the oil storage tank away from the arc-shaped main body, with the guide rail having the same curvature as the arc-shaped main body. The guide rails on adjacent oil storage tanks are interconnected. The large-span arched high-formwork support system also includes a self-powered drive vehicle, which slides in conjunction with the guide rail. A smoothing brush is installed on the drive vehicle, and the smoothing brush abuts against the outer wall of the arc-shaped main body.
[0007] By adopting the above technical solution, the assembled arc-shaped main body is placed on the ground, with the oil tank positioned above it. An adjusting component drives the opening and closing plate to slide towards the oil outlet, aligning the opening and closing hole with the corresponding oil outlet. At this point, the oil in the tank drips onto the outer wall of the arc-shaped main body. Next, the drive trolley is placed on the guide rail, sliding in coordination with it, so that the smoothing brush comes into contact with the outer wall of the arc-shaped main body. The drive trolley is then started, causing the smoothing brush to slide along the guide rail on the oil tank, thus spreading the oil dripping onto the outer wall of the arc-shaped main body evenly. This reduces the labor intensity for workers to some extent. After oiling, the drive trolley is removed from the guide rail, and the arc-shaped main body can be used immediately, which is simple and convenient. Furthermore, multiple arc-shaped main bodies can be assembled into an arc-shaped steel body using the same drive trolley for oiling, saving costs to some extent.
[0008] Preferably, the adjusting assembly includes a first slider, a second slider, a pusher, a first connector, and a second connector. The first slider slides through one side of the oil reservoir, and the second slider slides on the side of the oil reservoir away from the first slider. The sliding direction of the first slider is parallel to the arc direction of the oil reservoir, and the sliding directions of the first slider and the second slider are the same. The pusher is disposed on the oil reservoir and is used to push the first slider to slide towards the direction closer to the second slider. The first connector is disposed between the first slider and the second slider on the same oil reservoir and is used to fix the first slider and the second slider on the same oil reservoir relative to each other. The second connector is disposed between the first slider and the second slider on adjacent oil reservoirs and is used to fix the first slider and the second slider on adjacent oil reservoirs relative to each other. A connecting rod is disposed on one side of the opening and closing plate. One end of the connecting rod is connected to the first slider, and the other end is connected to the second slider. When the first slider slides away from the second slider on the same oil reservoir, the connecting rod drives the opening and closing hole on the opening and closing plate to slide towards the direction closer to the oil outlet.
[0009] By adopting the above technical solution, the first slider on the end oil tank is pulled away from the second slider. At this time, the first slider drives the second slider on the same oil tank to slide through the first connector. When the second slider slides, it drives the first slider on the adjacent oil tank to slide through the second connector, and so on. This achieves that the first slider and the second slider on each oil tank slide in the same direction. When the first slider and the second slider on the same oil tank slide, they drive the opening and closing plate to move through the connecting rod, so that the opening and closing hole on the opening and closing plate slides towards the direction of the oil outlet, aligning the opening and closing hole with the corresponding oil outlet, so that the oil outlet on each oil tank can be opened. The oil in the oil tank flows to the corresponding arc-shaped outer wall of the main body through the oil outlet, which saves manpower to a certain extent. After the oiling is completed, the first slider at the end is released, and the first slider is pushed to slide towards the second slider on the same oil tank through the pusher to reset. The first slider and the second connector drive the first slider and the second slider on other oil tanks to reset, so that the first slider and the second slider drive the opening and closing hole on the opening and closing plate away from the oil outlet, thus closing the oil outlet.
[0010] Preferably, the pusher includes a first spring for pushing the first slider to slide toward the direction of the second slider, one end of the first spring being disposed on the oil reservoir and the other end being disposed on the first slider.
[0011] By adopting the above technical solution, the first slider is pushed by the first spring to slide towards the second slider, which helps to reset the first and second sliders. The first and second sliders drive the opening and closing holes on the opening and closing plate away from the oil outlet through the connecting rod, thus closing the oil outlet. This helps to keep the oil outlet in a closed state when not in use.
[0012] Preferably, the first connecting member includes a fixing rod, which is disposed between a first slider and a second slider on the same oil tank. The fixing rod is an arc-shaped rod, and the arc of the fixing rod is the same as that of the oil tank.
[0013] By adopting the above technical solution, when the first slider slides, the second slider in the same oil tank moves synchronously through the fixed rod, so that the second slider can drive the first slider on the adjacent oil tank to slide, which facilitates the simultaneous opening of the oil outlet on all oil tanks. The operation is simple and helps to reduce the labor intensity of workers.
[0014] Preferably, the second connector includes a connecting block disposed on the side of the second slider away from the first slider, a snap-fit block slidably disposed on the connecting block, and a second spring disposed on the connecting block. The connecting block slidably passes through the oil reservoir. The sliding direction of the snap-fit block is perpendicular to the sliding direction of the second slider. The second spring is used to push the snap-fit block to slide away from the connecting block. The side of the snap-fit block away from the second slider is an arc surface, and the arc surface away from the connecting block is inclined towards the direction of the second slider. The side of the first slider away from the second slider has a connecting groove for snap-fitting with the connecting block on the adjacent oil reservoir. The inner wall of the connecting groove has a snap-fit groove for snap-fitting with the snap-fit block.
[0015] By adopting the above technical solution, the connecting block on the second slider is inserted into the connecting groove on the first slider on the adjacent oil tank. The inner wall of the connecting groove and the arc surface of the locking block slide relative to each other, pushing the locking block to slide towards the connecting block and compressing the second spring. When the connecting block moves the locking block to the locking groove, the second spring pushes the locking block to slide towards the locking groove, so that the locking block and the locking groove engage and cooperate, realizing that the second slider is relatively fixed with the first slider on the adjacent oil tank. This helps to simultaneously pull the first slider and the second slider on the oil tank to move, providing convenience for the opening and closing plates on multiple oil tanks to open or close the oil outlet at the same time, providing convenience for the operation of workers, and reducing the labor of workers to a certain extent.
[0016] Preferably, the snap-fit groove passes through the first slider, and the oil tank has an operating port for communicating with the snap-fit groove. A push rod is slidably disposed in the operating port for pushing the snap-fit block to slide towards the connecting block. The sliding direction of the push rod is parallel to the sliding direction of the snap-fit block. A third spring is sleeved on the push rod for pushing the push rod to slide away from the snap-fit block. One end of the third spring is disposed on the oil tank, and the other end is disposed on the side of the push rod away from the snap-fit block.
[0017] By adopting the above technical solution, when the template is used up and it is necessary to separate the arc-shaped main body, the push rod is slid towards the direction of the snap-fit block, so that the push rod pushes the snap-fit block towards the direction of the connecting block, and the snap-fit block disengages from the snap-fit groove. At this time, the connecting block can be easily removed from the connecting groove, which facilitates the separation of the arc-shaped main body. When the snap-fit block and the snap-fit groove are engaged, the third spring pushes the push rod away from the snap-fit block, which facilitates the engagement of the snap-fit block and the snap-fit groove. At the same time, the third spring has a certain fixing effect on the push rod, making it less likely for the push rod to fall off.
[0018] Preferably, the oil tank has oil passages on both sides facing each other. A closing door for opening and closing the oil passage is rotatably mounted on the inner wall of each oil passage. The closing door rotates towards or away from the oil passage. A magnet is mounted on one side of the closing door, and an iron plate is mounted on the other side. The magnet and iron plate on adjacent closing doors of the oil tank are used for attraction. The oil tank has a driving component for rotating the closing door towards the corresponding oil passage to close it. A third connecting component is provided between the two closing doors on the oil tank, which causes the other closing door to rotate in the same direction when one closing door rotates.
[0019] By adopting the above technical solution, the closed door on the end oil tank is rotated in the direction away from the oil tank. The closed door on one side drives the closed door on the other side of the oil tank to rotate in the same direction through the third connector. Since the closed doors on adjacent oil tanks are attracted by magnets and iron plates, the rotation of the closed door can drive the closed doors on adjacent oil tanks to rotate, realizing the opening of multiple closed doors and the connection between adjacent oil tanks. Then, the oil passage on the other end oil tank is sealed with external tools such as rubber plugs, so that engine oil can be added to multiple oil tanks at the same time without adding them individually, further saving manpower.
[0020] Preferably, the closed door is provided with a rotating shaft, which rotates on the inner wall of the oil passage. The driving component includes a torsion spring for driving the closed door to rotate toward the corresponding oil passage to close the oil passage. The torsion spring is movably sleeved on the rotating shaft, with one end of the torsion spring disposed on the closed door and the other end disposed on the oil storage tank.
[0021] By adopting the above technical solution, without the action of external force, the torsion spring drives the sealing door to seal the corresponding oil passage, thereby reducing the possibility of oil leakage in the oil tank.
[0022] Preferably, the third connecting member includes a connecting rod, one end of which is hinged to a closed door on one side, and the other end of which is hinged to a closed door on the other side.
[0023] By adopting the above technical solution, when the closed door on one side of the oil tank rotates, it drives one end of the connecting rod to move. At this time, the connecting rod pulls the closed door on the other side of the oil tank to rotate in the same direction, so as to make the adjacent oil tanks interconnected, which facilitates the simultaneous addition of engine oil to the oil tank and helps to save manpower.
[0024] Preferably, sealing gaskets are provided on both sides of the oil storage tank, and the sealing gaskets are arranged circumferentially along the oil passage.
[0025] By adopting the above technical solution, the sealing gasket enhances the sealing between adjacent oil tanks, making it less likely for oil to leak from the gaps between adjacent oil tanks when oil is added to the oil tanks at the same time.
[0026] In summary, this application includes at least one of the following beneficial technical effects: Place the assembled arc-shaped main body on the ground, positioning the oil reservoir above it. Adjust the control mechanism to drive the opening and closing plate, causing the opening and closing hole to slide towards the oil outlet, aligning the opening and closing hole with the corresponding oil outlet. At this point, the oil in the reservoir drips onto the outer wall of the arc-shaped main body. Next, place the drive trolley on the guide rail, allowing it to slide and engage with the guide rail, bringing the smoothing brush into contact with the outer wall of the arc-shaped main body. Then, start the drive trolley to move the smoothing brush along the guide rail on the oil reservoir, thus spreading the oil evenly on the outer wall of the arc-shaped main body, reducing the labor intensity for workers to some extent. After oiling, remove the drive trolley from the guide rail, and the arc-shaped main body can be used immediately—simple and convenient. Furthermore, multiple arc-shaped main bodies can be assembled into an arc-shaped steel body using the same drive trolley for oiling, saving costs to some extent. Rotate the closed door on the end oil tank away from the oil tank. The closed door on one side drives the closed door on the other side of the oil tank to rotate in the same direction through the third connector. Since the closed doors on adjacent oil tanks are attracted by magnets and iron plates, the rotation of the closed door can drive the closed doors on adjacent oil tanks to rotate, realizing the opening of multiple closed doors and the connection between adjacent oil tanks. Then, use external tools such as rubber plugs to seal the oil passage on the other end oil tank. Oil can be added to multiple oil tanks at the same time without adding them individually, further saving manpower. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0035] This application discloses a tall formwork support system for a large-span arched structure. (Refer to...) Figure 1 and Figure 2The large-span arched structure high-formwork support system includes multiple interconnected arc-shaped main bodies 1 and a self-powered drive vehicle 7. The inner wall of the arc-shaped main body 1 is used to connect with the scaffolding. An oil storage tank 2 is fixedly connected to one side of the arc-shaped main body 1. The curvature of the oil storage tank 2 is the same as that of the arc-shaped main body 1. The outer wall of the oil storage tank 2 is higher than that of the outer wall of the arc-shaped main body 1, that is, the distance from the outer wall of the oil storage tank 2 to the center is greater than the distance from the arc-shaped main body 1 to the center. Here, the center refers to the center point of the corresponding arc-shaped main body 1. A guide rail 6 is fixedly installed on the side of the oil storage tank 2 away from the arc-shaped main body 1. The curvature of the guide rail 6 is the same as that of the arc-shaped main body 1. The guide rails 6 on adjacent oil storage tanks 2 are connected to each other. The drive vehicle 7 is used to slide with the guide rail 6. The drive vehicle 7 can slide along the guide rail 6. An L-shaped mounting rod 24 is fixedly connected to the drive vehicle 7. A smoothing brush 8 is fixedly installed on the side of the mounting rod 24 away from the drive vehicle 7. The bristles of the smoothing brush 8 are used to abut against the outer wall of the arc-shaped main body 1.
[0036] Reference Figure 2 and Figure 4 The oil tank 2 has multiple oil outlets 3 on one side near the outer wall of the arc-shaped main body 1. The multiple oil outlets 3 are arranged at intervals along the length of the oil tank 2. An opening and closing plate 4 is slidably installed inside the oil tank 2. The opening and closing plate 4 has opening and closing holes 5 that correspond one-to-one with the oil outlets 3. The sliding direction of the opening and closing plate 4 is parallel to the arc direction of the oil tank 2. A guide block (not shown in the figure) is fixed on the side of the opening and closing plate 4 near the oil outlet 3. A guide groove (not shown in the figure) is provided on the inner wall of the oil tank 2 to slide in cooperation with the guide block, which helps to guide the sliding of the opening and closing plate 4. An adjustment component 9 is provided on the oil tank 2 to adjust the opening and closing plate 4 to drive the opening and closing holes 5 to slide in a direction closer to or away from the oil outlet 3.
[0037] Reference Figure 4 and Figure 5To facilitate the movement of the opening and closing plate 4, the adjusting assembly 9 includes a first slider 91, a second slider 92, a pusher 93, a first connector 94, and a second connector 95. The first slider 91 slides through one side of the oil reservoir 2. The cross-section of the first slider 91 is I-shaped. The oil reservoir 2 has a first sliding hole 25 for the first slider 91 to slide through. A placement groove 26 is provided on the outer wall of the oil reservoir 2 along the circumference of the first sliding hole 25. The side of the first slider 91 located outside the oil reservoir 2 is engaged in the placement groove 26. An elastic first oil-separating cloth (not shown in the figure) is fixedly installed along the circumference of the first sliding hole 25. The first oil-separating cloth is fixedly sleeved on the first slider 91. The first oil-separating cloth helps to reduce the possibility of oil leakage in the oil reservoir 2. The second slider 92 slides in the oil reservoir 2 on the side away from the first slider 91. The arrangement direction of the first slider 91 and the second slider 92 is parallel to the arc direction of the oil reservoir 2. The sliding direction of the first slider 91 and the second slider 92 are parallel to the arc direction of the oil reservoir 2. The arc direction of the oil tank 2 is parallel, and the sliding direction of the first slider 91 and the second slider 92 is the same. The pusher 93 is set on the oil tank 2 and is used to push the first slider 91 to slide towards the direction closer to the second slider 92. The first connector 94 is set between the first slider 91 and the second slider 92 on the same oil tank 2 and is used to fix the first slider 91 and the second slider 92 on the same oil tank 2 relative to each other. The second connector 95 is set between the first slider 91 and the second slider 92 on adjacent oil tanks 2 and is used to fix the first slider 91 and the second slider 92 on adjacent oil tanks 2 relative to each other. A connecting rod 10 is fixed on one side of the opening and closing plate 4. One end of the connecting rod 10 is fixed to the first slider 91, and the other end is fixed to the second slider 92. When the first slider 91 slides away from the second slider 92 on the same oil tank 2, the opening and closing hole 5 on the opening and closing plate 4 slides towards the corresponding oil outlet 3.
[0038] Reference Figure 4 and Figure 5 The pushing component 93 includes a first spring 931 for pushing the first slider 91 to slide toward the direction close to the second slider 92. The extension direction of the first spring 931 is parallel to the sliding direction of the first slider 91. One end of the first spring 931 is fixedly connected to the inner wall of the oil tank 2 near the first slider 91, and the other end is fixedly connected to the side of the first slider 91 near the second slider 92. In this embodiment, two first springs 931 are provided, which helps to improve the pushing effect.
[0039] Reference Figure 4 and Figure 5 The first connecting member 94 includes a fixing rod 941, which is fixedly disposed between the first slider 91 and the second slider 92 on the same oil tank 2. The fixing rod 941 is an arc-shaped rod, and the arc of the fixing rod 941 and the oil tank 2 are the same.
[0040] Reference Figure 5 and Figure 6 The second connecting member 95 includes a connecting block 951 fixedly disposed on the side of the second slider 92 away from the first slider 91, and a connecting block 951 slidably disposed on the side of the connecting block 951 away from the arc-shaped body 1 (see reference). Figure 4 The connecting block 951 has a snap-fit block 952 and a second spring 953. The connecting block 951 slides through the oil reservoir 2 on the side away from the first slider 91. The oil reservoir 2 has a second sliding hole 27 for the connecting block 951 to pass through. A second elastic oil separator cloth (not shown in the figure) is fixedly installed between the second sliding hole 27 and the second slider 92. The second oil separator cloth is fixedly sleeved on the connecting block 951. The second oil separator cloth helps to reduce the possibility of oil leakage from the second sliding hole 27. An extension groove 28 is provided along the circumference of the second sliding hole 27. The extension groove 28 is used for the first slider 91 on the adjacent oil reservoir 2 to slide into. The sliding direction of the snap-fit block 952 is perpendicular to the first slider 91. The sliding direction of the second slider 92 is such that the connecting block 951 has an installation groove 29 on the side away from the arc-shaped body 1 for the sliding of the locking block 952. One end of the second spring 953 is fixedly connected to the bottom wall of the installation groove 29, and the other end is fixedly connected to the side of the locking block 952 near the installation groove 29. The second spring 953 is used to push the locking block 952 to slide away from the installation groove 29. The side of the locking block 952 near the second slider 92 is a flat surface, and the side of the locking block 952 away from the second slider 92 is an arc surface. The side of the arc surface away from the connecting block 951 is inclined towards the direction of the second slider 92, that is, the width of the locking block 952 decreases in the direction away from the connecting block 951. In the absence of external force, the first spring 931 pushes the first slider 91 to cause the second slider 91 to abut against the inner wall of the oil tank 2, and at this time, the opening and closing hole 5 and the oil outlet 3 on the opening and closing plate 4 are misaligned.
[0041] Reference Figure 3 and Figure 5 The first slider 91 has a connecting groove 11 on the side away from the second slider 92 for insertion with the connecting block 951 on the adjacent oil tank 2. The connecting groove 11 is away from the arc-shaped body 1 (refer to...). Figure 4 A snap-fit groove 12 is provided on the inner wall of one side for snap-fitting with the snap-fit block 952. The snap-fit groove 12 passes through the side of the first slider 91 away from the arc-shaped body 1.
[0042] When support is required, multiple arc-shaped main bodies 1 are spliced together, causing the connecting block 951 on the second slider 92 to insert into the connecting groove 11 on the first slider 91 of the adjacent oil tank 2. As the connecting block 951 moves toward the connecting groove 11, the inner wall of the connecting groove 11 and the arc surface of the locking block 952 slide relative to each other, pushing the locking block 952 toward the mounting groove 29, compressing the second spring 953, until the connecting block 951 drives the locking block 952 to move into the locking groove. At position 12, the second spring 953 pushes the locking block 952 to slide away from the mounting groove 29, so that the locking block 952 and the locking groove 12 engage, fixing the second slider 92 and the first slider 91 on the adjacent oil tank 2. Then, multiple arc-shaped bodies 1 are spliced into an arc-shaped steel body, which is laid down on the ground so that the oil tank 2 is above the arc-shaped body 1. Then, the drive vehicle 7 is placed on the guide rail 6 near the first slider 91 on the end oil tank 2, and the end oil tank is pulled. The first slider 91 on the oil tank 2 moves away from the second slider 92. When the first slider 91 slides, it drives the second slider 92 on the same oil tank 2 to move in the same direction through the fixed rod 941. Since the second slider 92 is relatively fixed to the first slider 91 on the adjacent oil tank 2, it can pull the first slider 91 and the second slider 92 on the adjacent oil tank 2 to slide in the same direction. When the first slider 91 and the second slider 92 move, they drive the opening and closing hole 5 on the opening and closing plate 4 to slide towards the oil outlet 3 through the connecting rod 10, so that the opening and closing hole 5 and the oil outlet 3 are aligned. At this time, the oil in the oil tank 2 flows to the outer surface of the arc-shaped body 1 through the oil outlet 3. Then the drive vehicle 7 is started. The drive vehicle 7 drives the smoothing brush 8 through the mounting rod 24 to spread the oil evenly on the outer wall of the arc-shaped body 1, realizing the oiling and saving manpower to a certain extent. After the oiling is completed, the drive vehicle 7 is removed from the guide rail 6, and then the spliced arc-shaped steel body is installed in the required position and further supported by scaffolding. Since wooden structures are usually required on the outer wall of the arc-shaped steel body formed by splicing multiple arc-shaped main bodies 1 during construction, the fact that the oil tank 2 protrudes from the arc-shaped main body 1 will not affect the support of the arch structure.
[0043] Reference Figure 3 and Figure 5Oil tank 2 has oil passage holes 16 on opposite sides. A closing door 17 for opening and closing the oil passage hole 16 is rotatably mounted on the inner wall of the oil passage hole 16. The closing door 17 has a rectangular cross-section and a rotating shaft 20 is coaxially fixed to it. The rotating shaft 20 is rotatably mounted on the inner wall of the oil passage hole 16. The closing door 17 rotates towards or away from the oil passage hole 16, and its rotation axis is perpendicular to the plane of the oil passage hole 16. Closely adjacent closing doors 17 on adjacent oil tanks 2 abut against each other. The oil tank 2 is equipped with a mechanism to drive the closing door 17 to rotate towards the corresponding oil passage hole 16 to close it. The driving component of the oil passage 16 includes a torsion spring 21 for driving the closed door 17 to rotate toward the direction close to the corresponding oil passage 16. The torsion spring 21 is movably sleeved on the rotating shaft 20. One end of the torsion spring 21 is fixedly connected to the closed door 17, and the other end is fixedly connected to the inner wall of the oil passage 16. A magnet 18 is fixedly provided on the side of the closed door 17 near the first slider 91 away from the oil tank 2. An iron plate 19 is fixedly provided on the side of the closed door 17 near the second slider 92 away from the oil tank 2. The magnet 18 and the iron plate 19 on the closed door 17 adjacent to the oil tank 2 are attracted to each other.
[0044] Reference Figure 4 and Figure 5 A third connector is provided between the two closed doors 17 on the oil tank 2. The third connector is used to drive the other closed door 17 to rotate in the same direction when one closed door 17 rotates. The third connector includes a connecting rod 22. One end of the connecting rod 22 is hinged to the side of one closed door 17 near the oil tank 2, and the other end is hinged to the side of the other closed door 17 near the oil tank 2.
[0045] Pull the closed door 17 on the end oil tank 2 to rotate it away from the oil tank 2, opening the oil passage 16. The closed door 17, through the connecting rod 22, drives the closed door 17 on the other side to rotate towards the oil tank 2 and enter the oil tank 2. Since the two adjacent closed doors 17 on the adjacent oil tank 2 are attracted and cooperated by the magnet 18 and the iron plate 19, the rotation of the closed door 17 can drive the adjacent closed doors 17 to rotate in the same direction, realizing the interconnection between multiple oil tanks 2. At the same time, use external tools such as rubber plugs to block the oil passage 16 opened by the closed door 17 on the other end oil tank 2. At this time, engine oil can be injected into the opened oil passage 16. After adding, remove the rubber plug and release the closed door 17. At this time, the torsion spring 21 drives the closed door 17 to close the corresponding oil passage 16, so that engine oil can be added to multiple oil tanks 2 at the same time without individual operation, which reduces the labor intensity of workers to a certain extent.
[0046] Reference Figure 3Sealing gaskets 23 are adhered to both sides of the oil reservoir 2. The sealing gaskets 23 are arranged circumferentially along the oil passage 16. In this embodiment, the sealing gaskets 23 are rubber gaskets. When adjacent oil reservoirs 2 come into contact, the nearby sealing gaskets 23 abut against each other, thereby enhancing the sealing between the two nearby oil passages 16 on adjacent oil reservoirs 2. This makes it less likely for engine oil to leak through the oil passage 16 when adjacent oil reservoirs 2 are connected to each other.
[0047] Reference Figure 3 and Figure 6 Oil tank 2 is far away from the arc-shaped main body 1 (refer to) Figure 2 An operation port 13 is provided on one side of the first slider 91. The operation port 13 is used to communicate with the snap-fit groove 12 on the first slider 91. A push rod 14 is slidably arranged in the operation port 13 to push the snap-fit block 952 to slide towards the mounting groove 29. The sliding direction of the push rod 14 is parallel to the sliding direction of the snap-fit block 952. A push block 30 is fixed on the side of the push rod 14 near the snap-fit groove 12. A third spring 15 is sleeved on the push rod 14. The third spring 15 is used to push the push rod 14 to slide away from the snap-fit block 952. One end of the third spring 15 is fixedly connected to the outer wall of the oil tank 2 away from the arc-shaped body 1, and the other end is fixedly connected to the side of the push rod 14 away from the snap-fit block 952.
[0048] When multiple arc-shaped main bodies 1 need to be disassembled, press the push rod 14 towards the direction of the oil tank 2 to compress the third spring 15. The push rod 14 slides towards the direction of the first slider 91, so that the push block 30 on the push rod 14 and the locking block 952 abut and push the locking block 952 towards the direction of the mounting groove 29. The locking block 952 and the locking groove 12 disengage. At this time, the oil tank 2 can easily move the connecting block 951 out of the connecting groove 11 on the adjacent oil tank 2, realizing the separation between the first slider 91 and the second slider 92 on the adjacent oil tank 2. It is simple, convenient and easy to operate. When it is necessary to fix the second slider 92 and the first slider 91 on the adjacent oil tank 2 relative to each other, the third spring 15 fixes the position of the push rod 14 without the action of external force, which provides convenience for the locking block 952 and the locking groove 12 to engage.
[0049] The implementation principle of this application embodiment is as follows: When support is required, multiple arc-shaped main bodies 1 are spliced together, so that the connecting block 951 on the second slider 92 is inserted into the connecting groove 11 on the first slider 91 on the adjacent oil tank 2, so that the inner wall of the connecting groove 11 and the arc surface of the snap-fit block 952 slide relative to each other, and push the snap-fit block 952 to slide towards the mounting groove 29, compressing the second spring 953 until the connecting block 951 drives the snap-fit block 952 to move to the snap-fit groove 12, at which point the second spring 953 pushes the snap-fit block 952 to slide away from the mounting groove 29, so that the snap-fit block 952 and the snap-fit groove 12 snap together, and the second slider 92 and the first slider 91 on the adjacent oil tank 2 are relatively fixed.
[0050] Next, multiple arc-shaped main bodies 1 are spliced together to form an arc-shaped steel body. The arc-shaped steel body is laid down on the ground, so that the oil tank 2 is located above the arc-shaped main body 1. Then, the closed door 17 located on the end oil tank 2 is pulled and rotated in the direction away from the oil tank 2, so that the oil passage 16 is opened. The closed door 17 drives the closed door 17 on the other side to rotate into the oil tank 2 through the connecting rod 22. Since the two close closed doors 17 on the adjacent oil tank 2 are attracted and cooperated by the magnet 18 and the iron plate 19, the rotation of the closed door 17 can drive the adjacent closed doors 17 to rotate in the same direction, realizing the interconnection between multiple oil tanks 2. Then, the oil passage 16 opened by the closed door 17 on the other end oil tank 2 is blocked by external tools such as rubber plugs. At this time, engine oil can be injected into the opened oil passage 16. After the oil is added, the rubber plug is removed, the closed door 17 is released, and the torsion spring 21 drives the closed door 17 to close the corresponding oil passage 16.
[0051] Next, the drive vehicle 7 is placed on the guide rail 6 of the end oil tank 2, and then the first slider 91 on the end oil tank 2 is pulled to move away from the second slider 92. When the first slider 91 slides, it drives the second slider 92 on the same oil tank 2 to move through the fixed rod 941. The second slider 92 drives the first slider 91 on the adjacent oil tank 2 to slide, so that the first slider 91 and the second slider 92 on multiple oil tanks 2 can be pulled to slide in the same direction. When the first slider 91 and the second slider 92 move, they drive the opening and closing hole 5 on the opening and closing plate 4 to slide towards the oil outlet 3 through the connecting rod 10, so that the opening and closing hole 5 and the oil outlet 3 are aligned. At this time, the oil in the oil tank 2 flows to the outer surface of the arc-shaped body 1 through the oil outlet 3. The drive vehicle 7 is started, and the drive vehicle 7 drives the smoothing brush 8 through the mounting rod 24 to spread the oil evenly on the outer wall of the arc-shaped body 1, so as to achieve oiling of the steel template and save manpower to a certain extent. After the oiling is completed, the drive vehicle 7 is removed from the guide rail 6, and then the assembled arc-shaped steel body is installed in the required position and supported by scaffolding.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
