Description

Technical Field

[0001] This utility model belongs to the field of construction equipment, and specifically relates to a bridge pier coating machine. Background Technology

[0002] During the construction of bridge piers, especially after concrete pouring and during the concrete hardening process, it is necessary to maintain a certain level of humidity to ensure the normal hydration reaction of the cement and reduce the risk of the concrete surface drying out and the interior becoming too dry due to excessive evaporation, which would affect the strength and durability of the concrete. At the same time, it is also necessary to reduce the risk of cracking in the concrete due to high or low temperature environments. Therefore, it is necessary to cover the bridge piers with a membrane.

[0003] However, bridge piers are typically quite tall, so current methods for covering piers with protective film usually involve either erecting a support frame and manually wrapping the film, or using a crane to suspend the film roll, with workers standing on top of the pier coordinating with the crane operator to lower the roll at a uniform speed. Both methods not only increase construction costs but also introduce safety hazards for workers operating at heights. Utility Model Content

[0004] In view of the above problems, this application provides a bridge pier coating machine that can coat the piers without workers, thereby reducing the risk of construction workers working at heights.

[0005] This application provides a bridge pier coating machine, which includes a first mounting frame, a climbing mechanism, a rotating component, a first driving component, and a coating mechanism. The first mounting frame is fitted onto the outside of the pier. The first mounting frame has a first portion and a second portion arranged radially thereon. The inner diameter of the second portion is smaller than the inner diameter of the first portion, forming a stepped surface on the inner surface of the first mounting frame. The climbing mechanism drives the first mounting frame to move along the extension direction of the pier. The rotating component is rotatable and revolves around the axis of the first mounting frame, and is disposed on the stepped surface. The outer circumference of the rotating component abuts against the inner circumference of the first portion. The first driving component drives the rotating component to rotate. The coating mechanism includes a movable component disposed on the rotating component and a fixed rod disposed on the first mounting frame. The movable component is inserted into the film roll, and the fixed rod is used to wrap one end of the protective film.

[0006] Specifically, during the film coating of the pier, a first mounting frame is fitted over the pier, and a climbing mechanism enables the first mounting frame to reciprocate along the extension direction of the pier. During this process, a first driving component drives a rotating component to rotate around its own axis. Since the outer circumference of the rotating component abuts against the inner circumference of the first part, the friction between the rotating component and the first part causes the rotating component to rotate around the axis of the first mounting frame. This, in turn, causes the rotating component to drive the movable components in the film coating mechanism to rotate around the pier, which in turn drives the film roll to rotate around the pier. At this point, since one end of the protective film is wrapped around the fixed rod, the protective film is pulled out from the film roll and then wrapped around the pier. The climbing mechanism continues to reciprocate along the extension direction of the pier to apply multiple layers of film coating to the pier.

[0007] In the above technical solution, the bridge pier coating machine eliminates the need for workers to coat the piers, thereby reducing the risk of construction workers operating at heights.

[0008] In some embodiments, the inner circumferential side of the first portion is provided with teeth, and the rotating member is a gear that meshes with the teeth.

[0009] In the above technical solution, when the rotating component meshes with the teeth on the inner circumference of the first part to realize that the rotating component rotates around its own axis, it can revolve around the circumference of the first mounting frame. Therefore, compared with the case of relying on friction to realize the above transmission, it has the advantages of improving transmission efficiency, transmission accuracy, reducing the risk of slippage and improving transmission reliability.

[0010] In some embodiments, the stepped surface is recessed to form a first groove, the first groove being connected end to end and arranged around the axis of the first mounting frame, and one end of the rotating member is rotatably inserted into the first groove.

[0011] In the above technical solution, by setting the first groove, the rotating part can revolve around the axis of the first mounting frame along the extension direction of the first groove, which is simple in structure and easy to implement.

[0012] In some embodiments, the stepped surface is recessed to form a second groove, the first groove is connected end to end and arranged around the axis of the first mounting frame, and the first groove is located inside the second groove; the movable component includes a first horizontal member and a slider, the first horizontal member extends radially along the first mounting frame, and the other end of the rotating member away from the first groove is rotatably disposed on the first horizontal member; the slider is disposed on the side of the first horizontal member facing the stepped surface and is located in the second groove.

[0013] In the above technical solution, by setting a first horizontal member and a slider, when the rotating member revolves around the axis of the first mounting frame, the first horizontal member and the slider can revolve together around the axis of the first mounting frame to provide auxiliary support force for the rotating member, thereby improving the stability of the rotating member when revolving around the axis of the first mounting frame.

[0014] In some embodiments, the movable component further includes a second horizontal member, a movable rod, and a first elastic member: one end of the second horizontal member is rotatably disposed on the first horizontal member, and the rotation axis of the second horizontal member is parallel to the axis of the first mounting frame; the movable rod is disposed at the end of the second horizontal member away from the axis of the second horizontal member and close to the axis of the first mounting frame, and extends along the axis of the first mounting frame, the movable rod being used to pass through the film roll; the two ends of the first elastic member are respectively disposed on the first horizontal member and the second horizontal member, the first elastic member being used to provide an elastic force to the second horizontal member to drive the second horizontal member to rotate towards the first horizontal member.

[0015] In the above technical solution, by setting a first elastic member between the second horizontal member and the first horizontal member, when the movable component drives the membrane roll to rotate around the pier, the second horizontal member can rotate relative to the first horizontal member when the membrane roll itself gets stuck, thereby reducing the risk of the protective membrane breaking due to the membrane roll not being delivered in time because of the membrane roll itself getting stuck; and when the membrane roll itself recovers its rotation, the first elastic member can drive the second horizontal member structure to reset.

[0016] In some embodiments, the first horizontal member includes a housing and a connecting rod; the other end of the rotating member away from the first groove is rotatably disposed at one end of the housing facing the stepped surface, the periphery of the housing has a strip-shaped hole through which the second horizontal member passes, the strip-shaped hole extends circumferentially along the housing, and one end of the second horizontal member is rotatably disposed inside the housing; the connecting rod is disposed on the outer periphery of the housing and extends radially along the first mounting frame, and the slider is disposed on the side of the connecting rod facing the stepped surface.

[0017] In the above technical solution, by having a strip-shaped hole on the periphery of the housing for the second horizontal member to pass through, and extending the strip-shaped hole along the circumference of the housing, the second horizontal member can rotate along the circumference of the housing, and the strip-shaped hole can limit the rotation range of the second horizontal member, thereby reducing the risk of plastic deformation of the first elastic member caused by excessive rotation of the second horizontal member.

[0018] In some embodiments, the first mounting frame includes a first body and a second body, the first body and the second body enclosing each other to form a first receiving space for the pier to pass through, the first body and the second body being detachably connected.

[0019] In the above technical solution, the first body and the second body are detachably connected, which makes it easy to assemble the first mounting frame and fit it onto the outside of the pier; at the same time, it is easy to store and transport the first mounting frame when it is not in use.

[0020] In some embodiments, the climbing mechanism includes a second mounting frame, a climbing wheel, and a second driving member; the second mounting frame is coaxially arranged with the first mounting frame and is used to be sleeved on the outside of the pier; the climbing wheel is disposed on the second mounting frame and is used to abut against the pier, and the climbing wheel rotates about its axis to drive the second mounting frame to move along the extension direction of the pier; the second driving member is used to drive the climbing wheel to rotate.

[0021] In the above technical solution, the first and second mounting frames are driven to move along the extension direction of the pier column by means of the second driving climbing wheel, which is simple in structure and easy to implement.

[0022] In some embodiments, the climbing wheel is disposed in the second mounting frame and is radially movable along the first mounting frame; the climbing mechanism includes an adjustment component for driving the climbing wheel to move radially along the first mounting frame.

[0023] In the above technical solution, the climbing wheel is driven to move radially along the first mounting frame by adjusting the component to abut against the pier, so that the climbing mechanism can be adapted to piers of various radial sizes and shapes, thereby increasing the application range of the bridge pier film covering machine.

[0024] In some embodiments, the second mounting frame includes a plurality of mounting members and a plurality of connecting members, wherein the plurality of mounting members are connected end to end in sequence through the plurality of connecting members to form a second accommodating space through which the pier column passes, and the mounting members and the connecting members are detachably connected.

[0025] In the above technical solution, the mounting components and connectors are detachably connected, which facilitates the assembly of the second mounting frame onto the pier column; at the same time, it facilitates the storage and transportation of the second mounting frame when it is not in use.

[0038] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0039] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] During the construction of bridge piers, especially after concrete pouring and during the concrete hardening process, it is necessary to maintain a certain level of humidity to ensure the normal hydration reaction of the cement and reduce the risk of the concrete surface drying out and the interior becoming too dry due to excessive evaporation, which would affect the strength and durability of the concrete. At the same time, it is also necessary to reduce the risk of cracking in the concrete due to high or low temperature environments. Therefore, it is necessary to cover the bridge piers with a membrane.

[0043] However, bridge piers are typically quite tall, so current methods for covering piers with protective film usually involve either erecting a support frame and manually wrapping the film, or using a crane to suspend the film roll, with workers standing on top of the pier coordinating with the crane operator to lower the roll at a uniform speed. Both methods not only increase construction costs but also introduce safety hazards for workers operating at heights.

[0044] To solve the above technical problems, refer to Figure 1 and Figure 2This application provides a bridge pier coating machine 100, including a first mounting frame 10, a climbing mechanism 20, a rotating component 30, a first driving component, and a coating mechanism 40. The first mounting frame 10 is used to fit over the pier. The first mounting frame 10 has a first part 11 and a second part 12 arranged radially thereon. The inner diameter of the second part 12 is smaller than the inner diameter of the first part 11, so as to form a stepped surface 121 on the inner surface of the first mounting frame 10. The climbing mechanism 20 is used to drive the first mounting frame 10 to move along the extension direction of the pier. The rotating component 30 is disposed on the stepped surface 121 and can rotate on its own axis and revolve around the axis of the first mounting frame 10. The outer peripheral side of the rotating component 30 abuts against the inner peripheral side of the first part 11. The first driving component is used to drive the rotating component 30 to rotate. The coating mechanism 40 includes a movable component 41 disposed on the rotating component 30 and a fixed rod 42 disposed on the first mounting frame 10. The movable component 41 is used to pass through the film roll, and the fixed rod 42 is used to wrap one end of the protective film.

[0045] It should be noted that, for ease of description of the embodiments of this application, a first direction X, a second direction Y, and a third direction Z are introduced, wherein the third direction Z is parallel to the extension direction of the pier column, that is, during the use of the bridge pier column coating machine 100, the axis of the first mounting frame is parallel to the third direction Z, and the first direction X and the second direction Y are directions that are perpendicular to each other with the third direction Z. For example, when the extension direction of the pier column is parallel to the direction of gravity, the first direction X and the second direction Y are horizontal directions that are perpendicular to each other. That is, during the use of the bridge pier column coating machine 100, the first direction X and the second direction Y can be two mutually perpendicular radial directions of the first mounting frame 10.

[0046] The first part 11 and the second part 12 are two parts of the first mounting member 211 that are radially distributed and interconnected.

[0047] The statement "the inner diameter of the second part 12 is smaller than the inner diameter of the first part 11" can be understood as the inner circumference of the second part 12 protruding radially from the inner circumference of the first part 11 along the first mounting frame 10. This forms a stepped surface 121 on the inner circumference of the first mounting frame 10.

[0048] In some embodiments, a guide rail or guide groove may be provided on the step surface 121. The bridge pier coating machine 100 also includes a sliding member that can be slidably disposed on the guide rail or guide groove. One end of the rotating member can be rotatably disposed on the sliding member. The sliding member moves along the guide rail or groove to rotate about the axis of the first mounting frame 10.

[0049] The first driving component can be a drive motor, which is used to drive the rotating component 30 to rotate around the axis of the rotating component 30.

[0050] Understandably, during the use of the bridge pier film coating machine 100, both the fixed rod 42 and the movable component 41 should be located on the outside of the pier, and there should be a certain distance between them and the outer periphery of the pier along the radial direction of the pier. This is to prevent the movable component 41 from interfering with the pier when rotating around it. Understandably, the axis of the fixed rod 42 and the axis of the film roll are both parallel to the third direction Z.

[0051] Specifically, when covering the pier with film, the first mounting frame 10 is fitted over the pier, and the climbing mechanism 20 enables the first mounting frame 10 to reciprocate along the extension direction of the pier. During this period, the first driving member can drive the rotating member 30 to rotate around its own axis. Since the outer peripheral side of the rotating member 30 abuts against the inner peripheral side of the first part 11, the rotating member 30 rotates around its own axis due to the friction between the rotating member 30 and the first part 11. This causes the rotating component 30 to drive the movable component 41 in the film coating mechanism 40 to rotate around the pier, which in turn drives the film roll to rotate around the pier. At this time, since one end of the protective film is wrapped around the fixed rod 42, the protective film is pulled out from the film roll. At the same time, since the movable component 41 rotates around the pier, the protective film is applied to the pier. As the movable component 41 rotates around the pier, the protective film will be wrapped around the pier layer by layer. At this time, the climbing mechanism 20 continues to reciprocate along the extension direction of the pier to apply multiple layers of film to the pier.

[0052] In this technical solution, the bridge pier coating machine 100 eliminates the need for workers to coat the piers, thereby reducing the risk of construction workers operating at heights.

[0053] According to some embodiments of this application, please refer to Figures 2-4 The inner circumference of the first part 11 is provided with teeth 111, and the rotating part 30 is a gear that meshes with the teeth 111.

[0054] In this technical solution, the rotating member 30 is engaged with the teeth 111 on the inner circumferential side of the first part 11 so that when the rotating member 30 rotates around its own axis, it can revolve around the first mounting frame 10 in the circumferential direction. This improves the transmission efficiency and accuracy compared to the transmission method that relies on friction, while reducing the risk of slippage and improving the reliability of the transmission.

[0055] According to some embodiments of this application, please refer to Figure 2 and Figure 3 The stepped surface 121 is recessed to form a first groove 121A. The first groove 121A is connected end to end and arranged around the axis of the first mounting frame 10. One end of the rotating member 30 is rotatably inserted into the first groove 121A.

[0056] In this technical solution, by setting the first groove 121A, the rotating member 30 can revolve around the axis of the first mounting frame 10 along the extension direction of the first groove 121A, which is simple and easy to implement.

[0057] According to some embodiments of this application, please refer to Figures 1-5 The stepped surface 121 is recessed to form a second groove 121B. The first groove 121A is connected end to end and arranged around the axis of the first mounting frame 10. The first groove 121A is located inside the second groove 121B. The movable component 41 includes a first horizontal member 411 and a slider 412. The first horizontal member 411 extends radially along the first mounting frame 10. The other end of the rotating member 30 away from the first groove 121A is rotatably disposed on the first horizontal member 411. The slider 412 is disposed on the side of the first horizontal member 411 facing the stepped surface 121 and is located in the second groove 121B.

[0058] Understandably, the first horizontal member 411 can connect the rotating member 30 and the slider 412 so that the rotating member 30, the first horizontal member 411 and the slider 412 can slide simultaneously along the first groove 121A and the second groove 121B to rotate around the axis of the first mounting frame 10, thereby enabling the rotating member 30 to rotate more smoothly around the axis of the first mounting frame 10.

[0059] In this technical solution, by setting the first horizontal member 411 and the slider 412, when the rotating member 30 revolves around the axis of the first mounting frame 10, the first horizontal member 411 and the slider 412 can revolve together around the axis of the first mounting frame 10 to provide auxiliary support force for the rotating member 30, thereby improving the stability of the rotating member 30 when revolving around the axis of the first mounting frame 10.

[0060] According to some embodiments of this application, please refer to Figures 1-5 The movable component 41 also includes a second horizontal member 413, a movable rod 414, and a first elastic member 415: one end of the second horizontal member 413 is rotatably disposed on the first horizontal member 411, and the rotation axis of the second horizontal member 413 is parallel to the axis of the first mounting frame 10; the movable rod 414 is disposed at the end of the second horizontal member 413 away from the axis of the second horizontal member 413 and close to the axis of the first mounting frame 10, and extends along the axis of the first mounting frame 10, and the movable rod 414 is used to pass through the film roll; the two ends of the first elastic member 415 are respectively disposed on the first horizontal member 411 and the second horizontal member 413, and the first elastic member 415 is used to provide elastic force to the second horizontal member 413 to drive the second horizontal member 413 to rotate towards the first horizontal member 411.

[0061] The axis of the movable rod 414 is parallel to the third direction Z.

[0062] In some embodiments, a tray 4131 is provided at one end of the second horizontal member 413. The tray 4131 is provided at one end of the movable rod 414 for contacting the film roll in the third direction Z.

[0063] The first elastic element 415 can be a spring; for example, the first elastic element 415 can be a tension spring.

[0064] Understandably, when the pier is not cylindrical, such as rectangular or square, the direction of the tensile force on the membrane roll changes when it passes around the edge of the pier, causing the membrane roll to become stuck for a short period of time. During this time, as the membrane roll continues to rotate around the pier, the tensile force on the protective membrane increases, potentially leading to breakage. By setting a second horizontal member 413, the movable rod 414 and the membrane roll can rotate towards one of the edges of the pier, reducing the distance between the membrane roll and the edge, thereby reducing the tensile force on the protective membrane and lowering the risk of breakage. During this period, the first elastic member 415 is stretched, and subsequently shortens to reset the second horizontal member 413.

[0065] In this technical solution, by setting a first elastic member 415 between the second horizontal member 413 and the first horizontal member 411, the second horizontal member 413 can rotate relative to the first horizontal member 411 when the movable component 41 drives the membrane roll to rotate around the pier and the membrane roll itself gets stuck in rotation. This reduces the risk of the protective film breaking due to the membrane roll not being delivered in time because of the membrane roll itself getting stuck in rotation. When the membrane roll itself resumes rotation, the first elastic member 415 can drive the second horizontal member 413 to reset its structure.

[0066] According to some embodiments of this application, please refer to Figure 4 and Figure 5 The first horizontal member 411 includes a housing 4111 and a connecting rod 4112; the other end of the rotating member 30 away from the first groove 121A is rotatably disposed at the end of the housing 4111 facing the step surface 121, the periphery of the housing 4111 has a strip hole 4111A for the second horizontal member 413 to pass through, the strip hole 4111A extends along the circumference of the housing 4111, and one end of the second horizontal member 413 is rotatably disposed inside the housing 4111; the connecting rod 4112 is disposed on the outer periphery of the housing 4111 and extends radially along the first mounting frame 10, and the slider 412 is disposed on the side of the connecting rod 4112 facing the step surface 121.

[0067] In some embodiments, the first driving member may be disposed at one end of the housing 4111 away from the rotating member 30, and the output end of the first driving member passes through the housing 4111 and is connected to the rotating member 30 to drive the rotating member 30 to rotate about its own axis.

[0068] In this technical solution, by having a strip-shaped hole 4111A on the periphery of the housing 4111 for the second horizontal member 413 to pass through, and extending the strip-shaped hole 4111A along the circumference of the housing 4111, the second horizontal member 413 can rotate along the circumference of the housing 4111, and the strip-shaped hole 4111A can limit the rotation range of the second horizontal member 413, so as to reduce the risk of plastic deformation of the first elastic member 415 due to excessive rotation of the second horizontal member 413.

[0069] According to some embodiments of this application, please refer to Figure 6 The first mounting frame 10 includes a first body 10A and a second body 10B. The first body 10A and the second body 10B enclose each other to form a first receiving space for the pier column to pass through. The first body 10A and the second body 10B are detachably connected.

[0070] In some embodiments, the first body 10A and the second body 10B can be two parts arranged in a rotationally symmetrical manner.

[0071] For example, the first mounting frame 10 may also include a third body, a fourth body, and other multiple bodies, which together form a first accommodating space for the pier column to pass through.

[0072] In this technical solution, the first body and the second body are detachably connected, which facilitates the first mounting frame 10 to be fitted onto the outside of the pier by assembly; at the same time, it facilitates the storage and transportation of the first mounting frame 10 when it is not in use.

[0073] According to some embodiments of this application, please refer to Figure 2 and Figure 3 Please refer to Figure 7 The climbing mechanism 20 includes a second mounting frame 21, a climbing wheel 22, and a second driving member 23. The second mounting frame 21 is coaxially arranged with the first mounting frame 10 and is used to be sleeved on the outside of the pier. The climbing wheel 22 is disposed on the second mounting frame 21 and is used to abut against the pier. The climbing wheel 22 rotates around its axis to drive the second mounting frame 21 to move along the extension direction of the pier. The second driving member 23 is used to drive the climbing wheel 22 to rotate.

[0074] The climbing wheel 22 can be a wheel that rotates around its axis.

[0075] In some embodiments, there are multiple lifting wheels 22 spaced apart around the inner circumference of the second mounting frame 21, and the rotation axis of the lifting wheels 22 is perpendicular to the third direction Z. The lifting wheels 22 rotate to drive the second mounting frame 21 to move along the third direction Z.

[0076] In some embodiments, there are multiple pairs of lifting wheels 22, with each pair consisting of two wheels symmetrically arranged about the center of the second mounting frame 21. The lifting wheels 22 are Meyer wheels, and each pair of Meyer wheels rotates in opposite directions, with each pair of lifting wheels rotating either clockwise or counterclockwise.

[0077] In this technical solution, the first mounting frame 10 and the second mounting frame 21 are driven to move along the extension direction of the pier column by means of the second driving climbing wheel 22, which is simple in structure and easy to implement.

[0078] According to some embodiments of this application, please refer to Figure 8 The climbing wheel 22 is disposed on the second mounting frame 21 and is movable radially along the first mounting frame 10; the climbing mechanism 20 includes an adjustment component 24 for driving the climbing wheel 22 to move radially along the first mounting frame 10.

[0079] In some embodiments, the adjustment component 24 may be a driving component such as a cylinder, hydraulic cylinder or electric telescopic rod, and the climbing wheel 22 is installed at the output end of the adjustment component 24.

[0080] In some embodiments, the adjusting assembly 24 includes a first bracket 241, a lead screw 242, a first mounting plate 243, a guide rod 244, a second elastic element 245, and a second bracket 246. One end of the first bracket 241 is provided with a second mounting plate 2411, which has an open structure at one end. One end of the second bracket 246 is slidably inserted into the first bracket 241, and the other end is located outside the first bracket 241 and is provided with a lifting wheel 22. The lead screw 242 is rotatably mounted on the second mounting plate 2411, and the lead screw 242 rotates to move along the second mounting plate 2411. The plate 2411 moves in the thickness direction. The first mounting plate 243 is rotatably disposed at one end of the lead screw 242 located inside the first bracket 241 and is adapted to the inner circumference of the first bracket 241. One end of the guide rod 244 is disposed on the side of the first mounting plate 243 away from the lead screw 242, and the other end of the guide rod 244 is inserted into the second bracket 246. The second elastic member 245 is sleeved on the outside of the guide rod 244, and the two ends of the second elastic member 245 abut against the first mounting plate 243 and the second bracket 246 respectively.

[0081] Specifically, rotating the lead screw 242 drives the first mounting plate 243 to move, which in turn causes the first mounting plate 243 to drive the second elastic element 245 and the first bracket 241 to move radially along the second mounting frame 21, so that the climbing wheel 22 abuts against the pier. Then, the lead screw 242 is rotated further so that the first mounting plate 243 continues to move, compressing the second elastic element 245, and pressing the second bracket 246 against the pier through the elastic force of the second elastic element 245.

[0082] In this technical solution, the climbing wheel 22 is driven to move radially along the first mounting frame 10 by adjusting component 24 to abut against the pier, so that the climbing mechanism 20 can be adapted to piers of various radial sizes and shapes, thereby increasing the application range of the bridge pier film covering machine 100.

[0083] According to some embodiments of this application, Figures 9-11 The second mounting frame 21 includes multiple mounting components 211 and multiple connecting components 212. The multiple mounting components 211 are connected end to end in sequence through the multiple connecting components 212 to form a second accommodating space for the pier column to pass through. The mounting components 211 and the connecting components 212 are detachably connected.

[0084] In some embodiments, the connector 212 includes a connecting portion 2121, a support rod 2122, and a third mounting plate 2123. Along the third direction Z, the support rod 2122 is located between the connecting portion 2121 and the third mounting plate 2123. The two ends of the support rod 2122 are respectively connected to the connecting portion 2121 and the third mounting plate 2123. The third mounting plate 2123 is used for detachably mounting the first mounting frame 10. Mounting member 211 includes two insertion sections 211A and mounting sections 211B. Two insertion sections 211A are located at opposite ends of mounting section 211B in its extending direction. Each insertion section 211A has a second pin hole 211C spaced apart along its extending direction. Connecting part 2121 has an insertion hole 2121A for inserting the insertion sections 211A. On one side of the connecting part 2121 in the third direction Z, there is a first pin hole 2121B corresponding to the second pin holes 211C. A pin 213 passes sequentially through the first pin hole 2121B and the second pin hole 211C to detachably connect connecting member 212 and mounting member 211. Adjustment component 24 is disposed on the mounting part in the third direction Z, located between the mounting part and the first mounting frame 10.

[0085] In this technical solution, the mounting component 211 and the connector 212 are detachably connected, which facilitates the second mounting frame 21 to be fitted onto the pier column by assembly; at the same time, it facilitates the storage and transportation of the second mounting frame 21 when it is not in use.

[0086] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
