Description

Technical Field

[0001] The invention belongs to the field of construction devices, and in particular relates to a McLennan type pier coating machine. Background Art

[0002] During the construction of bridge piers, especially after concrete pouring and during the concrete hardening process, in order to maintain a certain humidity to ensure the normal hydration reaction of cement, reduce the risk of dry concrete surface and insufficient internal moisture due to rapid evaporation of water, which affects the strength and durability of concrete. At the same time, in order to reduce the risk of cracks in concrete due to high or low temperature environments, bridge piers need to be covered with a film.

[0003] After the applicant's search, it was found that the invention patent with publication number CN115573258B and its name "Girder Beam Side Extrusion Type Automated Pier Maintenance Coating Device and Construction Method" mentioned a coating device including: a rotating base and a second driving member; the rotating base is annular in structure, surrounding the outside of the pier, the second driving member is connected to the rotating base, and is used to drive the rotating base to rotate; the coating system includes a reel, a film roll and a film hanging rod, the reel is arranged on the rotating base, the film hanging rod is arranged on the frame, the film roll includes a curing film wound on the reel, and the outer end of the film roll is connected to the film hanging rod; the film roll releases the curing film as the rotating base rotates, so that the curing film covers the outside of the pier.

[0004] However, the lifting mechanism in the prior art adopts an ordinary wheel to abut against the pier, and the rotation axis of the wheel is perpendicular to the extension direction of the pier, so that the rotation of the wheel can drive the coating device to move along the extension direction of the pier. However, since the peripheral rotation direction of the wheel is tangent to the extension direction of the pier, when passing through the coated area along the pier, especially when passing through the edge area of ​​the protective film, the reverse force provided by the wheel will cause the protective film to wrinkle, resulting in a large distance between the protective film layers when the next layer of protective film is attached to the current layer of protective film, which leads to a reduced sealing effect, resulting in insufficient internal moisture, and the risk of affecting the strength and durability of the concrete. Summary of the invention

[0005] In view of the above problems, an embodiment of the present application provides a McLennan-type pier laminating machine, which can improve the sealing performance of the protective film.

[0006] The embodiment of the present application provides a wheat wheel type pier column laminating machine, including a first installation frame, a driving mechanism, a laminating mechanism and a climbing mechanism. The first installation frame is used to be sleeved outside the pier column; the driving mechanism is arranged on the first installation frame; the laminating mechanism includes a movable component connected to the driving mechanism and a fixed rod arranged on the first installation frame, the movable component is used to be inserted into the film roll, the fixed rod is used to wrap one end of the protective film, and the driving mechanism is used to drive the movable component to rotate around the axis of the first installation frame; the climbing mechanism includes at least one pair of climbing wheels and a second driving member. The climbing wheels are wheat wheels, each pair of climbing wheels is symmetrically arranged on the first installation frame and has two opposite rotation directions, the climbing wheels are located below the laminating mechanism, and are used to abut against the pier column, the climbing wheels rotate around their axis to drive the first installation frame to move along the extension direction of the pier column, and the axis of the climbing wheels is parallel to the axis of the first installation frame; the second driving member is used to drive the climbing wheels to rotate.

[0007] Specifically, when coating the pier of the coating mechanism, the first installation frame is sleeved outside the pier, and the climbing mechanism is used to enable the first installation frame to reciprocate along the extension direction of the pier, during which the driving mechanism can drive the movable component to rotate around the axis of the first installation frame. The rotating member then drives the movable component in the coating mechanism to rotate around the pier, and then drives the film roll to rotate around the pier. At this time, since one end of the protective film is wound around the fixed rod, the protective film is pulled out from the film roll and then wound around the pier. At this time, the climbing mechanism continues to move along the extension direction of the pier to pass through the coated area. Since the climbing wheel is a wheat wheel and the axis of the climbing wheel is parallel to the extension direction of the pier, the outer peripheral rotation direction of the climbing wheel is close to tangent to the extension direction of the protective film, thereby reducing the risk of wrinkling of the protective film due to the rotation of the climbing wheel, thereby improving the sealing of the protective film. At the same time, when the climbing wheel is a wheat wheel, the reliability of the self-locking of the climbing mechanism can be improved. Compared with the traditional clamp-type vertical climbing mechanism, the climbing and descending processes are more continuous, which can not only ensure its coating speed, but also the uninterrupted descent during descent can ensure the continuity of the coating, so as to achieve the purpose of optimizing the coating effect. Compared with the traditional rotary wheel climbing mechanism, the wheat wheel does not need to tilt and rotate to rise and fall to ensure the upward component speed, which means that it can rise and fall vertically, so as to adapt to bridge piers of different shapes.

[0008] In the above technical solution, by replacing the climbing wheel with a wheat wheel, the risk of wrinkling of the protective film caused by the reverse force provided by the rotating wheel is reduced, thereby improving the sealing performance of the protective film.

[0009] In some embodiments, the first installation frame has a first part and a second part arranged along its radial direction, the inner diameter of the second part is smaller than the inner diameter of the first part, so as to form a step surface on the inner surface of the first installation frame; the driving mechanism includes a first driving member. The rotating member can rotate and revolve around the axis of the first installation frame and is arranged on the step surface, the inner circumference of the first part is provided with a first tooth, and the rotating member is a first gear meshing with the first tooth; the first driving member is used to drive the rotating member to rotate.

[0010] Specifically, when coating the pier column, the first installation frame is sleeved outside the pier column, and the climbing mechanism is used to enable the first installation frame to reciprocate along the extension direction of the pier column. During this period, the first driving member can drive the rotating member to rotate around its own axis. Since the rotating member is meshed with the first teeth on the inner circumference of the first part, when the rotating member rotates around its own axis, the rotating member rotates around the axis of the first installation frame. The rotating member then drives the movable component in the coating mechanism to rotate around the pier column, and then drives the film roll to rotate around the pier column. At this time, 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 column. At this time, the climbing mechanism continues to reciprocate along the extension direction of the pier column to perform multi-layer coating on the pier column. Compared with the situation where the above-mentioned transmission is achieved by relying on friction, the transmission efficiency and transmission accuracy are improved, the risk of slipping is reduced, and the reliability of the transmission is improved.

[0011] In some embodiments, the step surface is recessed to form a first groove, the first grooves are connected end to end and are arranged around the axis of the first mounting frame, and one end of the rotating member is rotatably inserted in the first groove; the step surface is recessed to form a second groove, the first grooves are connected end to end and are arranged around the axis of the first mounting frame, and the first groove is located on the inner side of 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 set on the first horizontal member; the slider is set on the side of the first horizontal member facing the step surface, and is located in the second groove.

[0012] In the above technical solution, the first groove is provided so that the rotating member can revolve around the axis of the first installation frame along the extension direction of the first groove, and the structure is simple and easy to implement. At the same time, the first horizontal member and the slider are provided so that when the rotating member revolves around the axis of the first installation frame, the first horizontal member and the slider can revolve around the axis of the first installation frame together, so as to provide auxiliary support force for the rotating member, thereby improving the stability of the rotating member when it revolves around the axis of the first installation frame.

[0013] In some embodiments, the McLennan pier laminating machine further includes an inner gear, an insert block, a switching assembly and a second gear. The inner gear is rotatably arranged on the inner wall of the second part, and a third groove is arranged at one end of the inner gear facing the first part along a third direction, and the third direction is parallel to the axis of the first mounting frame; the insert block is slidably arranged at one end of the first horizontal member away from the rotating member along the third direction, and the third groove is adapted to the insert block, and the insert block has a first position and a second position. In the first position, one end of the insert block is located in the third groove, and in the second position, the insert block leaves the third groove; the switching assembly is used to drive the insert block to switch between the first position and the second position; the second gear is detachably connected to the climbing wheel, and the second gear is meshed with the inner gear.

[0014] Specifically, when the device is climbing to coat the pier column, the second driving member may not work at this time, and the switching assembly may be used to drive the insertion block to the first position, so that when the first driving member drives the first horizontal member to rotate around the axis of the first installation frame, the internal gear can be driven to rotate through the insertion block, thereby driving the second gear and the climbing wheel to rotate. Therefore, by adjusting the gear ratio of the second gear and the internal gear, the number of turns of the climbing wheel when the film is wound around the pier column can be adjusted, and then the distance of the first installation frame moving along the extension direction of the pier column can be roughly adjusted, on the one hand, so that the protective film can cover the pier column more evenly, and on the other hand, the rotation direction of the outer periphery of the climbing wheel can be tangent to the extension direction of the protective film abutting against the outer periphery through the above adjustment, thereby further reducing the risk of wrinkling of the protective film; when the device is descending to continue coating the pier column, the switching assembly may be used to drive the insertion block to the second position, so that when the first driving member drives the first horizontal member to rotate around the axis of the first installation frame, it will not interfere with the second driving member driving the climbing wheel to rotate to drive the first installation frame to descend.

[0015] In some embodiments, the third grooves are multiple and spaced apart along the circumference of the first mounting frame.

[0016] In the above technical solution, a plurality of third grooves are arranged at intervals along the circumference of the first installation frame to facilitate the insertion of the insertion block.

[0017] In some embodiments, the switching assembly includes a third driving member, a second guide rod and a third elastic member. The third driving member is arranged on the first horizontal member, and a mounting block is arranged at the output end of the third driving member, and the third driving member is used to drive the mounting block to move along the third direction; one end of the second guide rod is connected to the insertion block, and the mounting block has a guide hole on the side facing the inner gear, and the other end of the second guide rod can be inserted into the guide hole to move along the third direction; the third elastic member is sleeved outside the second guide rod, and the two ends of the third elastic member are respectively in contact with the insertion block and the mounting block.

[0018] Specifically, the third driving member drives the mounting block to move along the third direction. When the insertion block can be directly inserted into the third groove, the mounting block can drive the second guide rod, the third elastic member and the insertion block to move along the third direction. When the insertion block can abut against the non-third groove area of ​​the internal gear, the mounting block compresses the third elastic member so that when the insertion block can be directly inserted into the third groove, the elastic force provided by the third elastic member enables the insertion block to be inserted into the third groove.

[0019] In some embodiments, the movable component also includes a second horizontal member, a movable rod and a first elastic member: one end of the second horizontal member is rotatably set 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 set at one end of the second horizontal member away from the axis of the second horizontal member close to the first mounting frame, and extends along the axis of the first mounting frame, and the movable rod is used to be passed through the film roll; the two ends of the first elastic member are respectively set on the first horizontal member and the second horizontal member, and the first elastic member is used to provide elastic force to the second horizontal member to drive the second horizontal member to rotate toward the direction close to the first horizontal member.

[0020] In the above technical solution, a first elastic member is arranged between the second horizontal member and the first horizontal member, so that when the movable component drives the film winding pier to rotate, when the film roll itself is stuck in rotation, the second horizontal member can be rotated relative to the first horizontal member, so as to reduce the risk of untimely film discharge due to the jamming of the film roll itself, and thus causing the risk of protective film breakage; and when the film roll itself resumes its rotation, the first elastic member can drive the second horizontal member structure to reset.

[0021] In some embodiments, the first horizontal member includes a shell and a connecting rod; the other end of the rotating member away from the first groove is rotatably arranged at the end of the shell facing the step surface, and the peripheral side of the shell has a strip hole for the second horizontal member to pass through, and the strip hole extends along the circumference of the shell, and one end of the second horizontal member is rotatably arranged in the shell; the connecting rod is arranged on the outer peripheral side of the shell and extends radially along the first mounting frame, and the slider is arranged on the side of the connecting rod facing the step surface.

[0022] In some embodiments, a strip hole is provided on the circumferential side of the shell for the second horizontal member to pass through, and the strip hole is extended along the circumference of the shell so that the second horizontal member can rotate along the circumference of the shell, and the strip hole can limit the rotation range of the second horizontal member, so as to reduce the risk of plastic deformation of the first elastic member due to excessive rotation of the second horizontal member.

[0023] In some embodiments, the first installation frame includes a first body and a second body, the first body and the second body are combined to form a first accommodating space for the pier to pass through, and the first body and the second body are detachably connected.

[0024] In the above technical solution, the first body and the second body are detachably connected, so that the first installation frame can be easily assembled and mounted outside the pier; at the same time, the first installation frame can be easily stored and transported when not in use.

[0025] In some embodiments, the climbing mechanism further includes a second mounting frame and an adjustment assembly. The second mounting frame is coaxially arranged with the first mounting frame and is used to be sleeved outside the pier column, and the climbing wheel is movably arranged in the second mounting frame along the radial direction of the first mounting frame; the adjustment assembly is used to drive the climbing wheel to move along the radial direction of the first mounting frame.

[0026] In the above technical solution, the climbing wheel is driven by the adjustment component to move radially along the first mounting frame to abut against the pier, so that the climbing mechanism can be adapted to piers of various radial sizes and shapes, thereby increasing the scope of use of the McWheel pier laminating machine.

[0027] In some embodiments, the second installation frame includes multiple installation members and multiple connecting members, and the multiple installation members are connected end to end in sequence through the multiple connecting members to form a second accommodating space for the pier to pass through, and the installation members and the connecting members are detachably connected.

[0028] In the above technical solution, the mounting member and the connecting member are detachably connected, so that the second mounting frame can be easily mounted outside the pier by assembly; at the same time, the second mounting frame can be easily stored and transported when not in use.

DETAILED DESCRIPTION

[0031] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0032] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] During the construction of bridge piers, especially after concrete pouring and during the concrete hardening process, in order to maintain a certain humidity to ensure the normal hydration reaction of cement, reduce the risk of dry concrete surface and insufficient internal moisture due to rapid evaporation of water, which affects the strength and durability of concrete. At the same time, in order to reduce the risk of cracks in concrete due to high or low temperature environments, bridge piers need to be covered with a film.

[0036] After the applicant's search, it was found that the invention patent with publication number CN115573258B and its name "Girder Beam Side Extrusion Type Automated Pier Maintenance Coating Device and Construction Method" mentioned a coating device including: a rotating base and a second driving member; the rotating base is annular in structure, surrounding the outside of the pier, the second driving member is connected to the rotating base, and is used to drive the rotating base to rotate; the coating system includes a reel, a film roll and a film hanging rod, the reel is arranged on the rotating base, the film hanging rod is arranged on the frame, the film roll includes a curing film wound on the reel, and the outer end of the film roll is connected to the film hanging rod; the film roll releases the curing film as the rotating base rotates, so that the curing film covers the outside of the pier.

[0037] However, the lifting mechanism in the prior art uses an ordinary wheel to abut against the pier column, and the rotation axis of the wheel is perpendicular to the extension direction of the pier column, so that the rotation of the wheel can drive the coating device to move along the extension direction of the pier column. However, since the peripheral rotation direction of the wheel is tangent to the extension direction of the pier column, when passing through the coated area along the pier column, especially when passing through the edge area of ​​the protective film, the reverse force provided by the wheel will cause the protective film to wrinkle, and because the device is blocked during the coating process, the above technical problems are difficult to be discovered. As a result, when the next layer of protective film is attached to the current layer of protective film, the distance between the protective film layers is large, which leads to a reduced sealing effect, insufficient internal moisture, and the risk of affecting the strength and durability of the concrete.

[0038] In order to solve the above technical problems, refer to Figure 1 and Figure 2 The embodiment of the present application provides a McLennan-type pier laminating machine, comprising a first mounting frame 10, a driving mechanism, a laminating mechanism 40 and a climbing mechanism 20. The first mounting frame 10 is used to be sleeved outside the pier; the driving mechanism is arranged on the first mounting frame 10; the laminating mechanism 40 comprises a movable component 41 connected to the driving mechanism and a fixed rod 42 arranged on the first mounting frame 10, the movable component 41 is used to be inserted into the film roll, the fixed rod 42 is used to wrap one end of the protective film, and the driving mechanism is used to drive the movable component 41 to rotate around the axis of the first mounting frame 10; the climbing mechanism 20 comprises at least one pair of climbing wheels 22 and a second driving member 23. The climbing wheels 22 are wheat wheels, and each pair of climbing wheels 22 are two wheels symmetrically arranged on the first mounting frame 10 and rotating in opposite directions. The climbing wheels 22 are located below the coating mechanism 40 and are used to abut against the pier. The climbing wheels 22 rotate around their axes to drive the first mounting frame 10 to move along the extension direction of the pier. The axes of the climbing wheels 22 are parallel to the axes of the first mounting frame 10. The second driving member 23 is used to drive the climbing wheels 22 to rotate.

[0039] It should be noted that, in order to facilitate the description of the embodiment of the present 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, that is, during the use of the McLen type pier laminating machine, 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 perpendicular to the third direction Z in pairs. Exemplarily, when the extension direction of the pier is parallel to the direction of gravity, the first direction X and the second direction Y are mutually perpendicular horizontal directions, that is, during the use of the McLen type pier laminating machine, the first direction X and the second direction Y can be two mutually perpendicular radial directions of the first mounting frame 10.

[0040] It is understandable that during the use of the McLennan type pillar laminating machine, the fixed rod 42 and the movable assembly 41 should be located outside the pillar, and there should be a certain distance between the fixed rod 42 and the outer periphery of the pillar along the radial direction of the pillar. This is to prevent the movable assembly 41 from interfering with the pillar when rotating around the pillar. It is understandable that the axis of the fixed rod 42 and the axis of the film roll are both parallel to the third direction Z.

[0041] The Mecanum Wheel is a specially designed wheel that can achieve omnidirectional movement, that is, translation and rotation in any direction.

[0042] The main roller 222 of the wheat wheel has a plurality of sub-rollers 221 (usually arranged at a 45 degree angle) on its surface, and these sub-rollers 221 form a certain angle (usually 45 degrees or 60 degrees) with the axis of the main roller 222. This design enables the wheat wheel to generate lateral force when rolling.

[0043] “Each pair of climbing wheels 22 are two climbing wheels symmetrically arranged on the first mounting frame 10 and rotating in opposite directions” means that the inclination directions of the sub-rollers 221 of the two climbing wheels 22 are opposite, so that when the two climbing wheels 22 rotate in the same direction (rotate counterclockwise or clockwise), the circumferential component forces generated by the two climbing wheels 22 can offset each other.

[0044] The second driving member 23 may be a driving motor, which is used to drive the climbing wheel 22 to rotate around the axis of the main roller 222 .

[0045] Specifically, when coating the pier of the coating mechanism 40, the first installation frame 10 is sleeved outside the pier, and the first installation frame 10 can reciprocate along the extension direction of the pier through the climbing mechanism 20, during which the driving mechanism can drive the movable component 41 to rotate around the axis of the first installation frame 10. Then the rotating member 30 drives the movable component 41 in the coating mechanism 40 to rotate around the pier, and then drives the film roll to rotate around the pier. At this time, since one end of the protective film is wound around the fixing rod 42, the protective film is pulled out from the film roll and then wound around the pier. At this time, the climbing mechanism 20 continues to move along the extension direction of the pier to pass through the coated area. Since the climbing wheel 22 is a wheat wheel and the axis of the climbing wheel 22 is parallel to the extension direction of the pier, the outer peripheral rotation direction of the climbing wheel 22 is close to the extension direction of the protective film, thereby reducing the risk of wrinkling of the protective film caused by the rotation of the climbing wheel 22, thereby improving the sealing of the protective film. At the same time, when the climbing wheel 22 is a wheat wheel, the self-locking reliability of the climbing mechanism 20 can be improved. Compared with the traditional clamp-type vertical climbing mechanism 20, the climbing and descending processes are more continuous, which can not only ensure its coating speed, but also the uninterrupted descent during descent can ensure the continuity of the coating, thereby achieving the purpose of optimizing the coating effect. Compared with the traditional rotary climbing mechanism 20, the wheat wheel does not need to tilt and rotate to rise and fall to ensure the upward component speed, which means that it can rise and fall vertically, so as to adapt to bridge piers of different shapes.

[0046] In the present technical solution, by replacing the climbing wheel 22 with a wheat wheel, the risk of wrinkling of the protective film due to the reverse force provided by the rotating wheel is reduced, thereby improving the sealing performance of the protective film.

[0047] According to some embodiments of this application, please refer to Figure 1 and Figure 2 , and please refer to Figure 4 The first installation frame 10 has a first part 11 and a second part 12 arranged along its radial direction. The inner diameter of the second part 12 is smaller than the inner diameter of the first part 11, so as to form a step surface 121 on the inner surface of the first installation frame 10; the driving mechanism includes and a first driving member. The rotating member 30 can rotate and revolve around the axis of the first installation frame 10 and is arranged on the step surface 121. The inner circumference of the first part 11 is provided with a first tooth 111. The rotating member 30 is a first gear meshing with the first tooth 111; the first driving member is used to drive the rotating member 30 to rotate.

[0048] The first portion 11 and the second portion 12 are two portions of the first mounting member 211 distributed along the radial direction thereof and connected to each other.

[0049] “The inner diameter of the second portion 12 is smaller than the inner diameter of the first portion 11 ” can be understood as the inner circumference of the second portion 12 protrudes from the inner circumference of the first portion 11 along the radial direction of the first installation frame 10 . Thus, a step surface 121 is formed on the inner circumference of the first installation frame 10 .

[0050] In some embodiments, a guide rail or guide groove can be set on the step surface 121, and the McLennan pier laminating machine also includes a sliding member that can be slidably set on the guide rail or guide groove, one end of the rotating member can be rotatably set on the sliding member, and the sliding member moves along the guide rail or guide groove to rotate around the axis of the first mounting frame 10.

[0051] The first driving member may be a driving motor, which is used to drive the rotating member 30 to rotate around the axis of the rotating member 30 .

[0052] It is understandable that during the use of the McLennan type pillar laminating machine, the fixed rod 42 and the movable assembly 41 should be located outside the pillar, and there should be a certain distance between the fixed rod 42 and the outer periphery of the pillar along the radial direction of the pillar. This is to prevent the movable assembly 41 from interfering with the pillar when rotating around the pillar. It is understandable that the axis of the fixed rod 42 and the axis of the film roll are both parallel to the third direction Z.

[0053] Specifically, when coating the pier column, the first installation frame 10 is sleeved outside the pier column, and the first installation frame 10 can reciprocate along the extension direction of the pier column through the climbing mechanism 20. During this period, the first driving member can drive the rotating member 30 to rotate around its own axis. Since the rotating member 30 is meshed with the first teeth 111 on the inner circumference of the first part 11, when the rotating member 30 rotates around its own axis, the rotating member 30 rotates around the axis of the first installation frame 10. Then the rotating member 30 drives the movable component 41 in the coating mechanism 40 to rotate around the pier column, and then drives the film roll to rotate around the pier column. At this time, since one end of the protective film is wound around the fixed rod 42, the protective film is pulled out from the film roll and then wound around the pier column. At this time, the climbing mechanism 20 continues to reciprocate along the extension direction of the pier column to perform multi-layer coating on the pier column. Therefore, compared with the case where the above-mentioned transmission is realized by relying on friction, the transmission efficiency and transmission accuracy are improved, and the risk of slipping is reduced and the reliability of the transmission is improved.

[0054] According to some embodiments of this application, please refer to Figure 1 and Figure 2 , and please refer to Figure 4 and Figure 5The step surface 121 is recessed to form a first groove 121A, the first grooves 121A are connected end to end and are arranged around the axis of the first installation frame 10, and one end of the rotating member 30 is rotatably inserted in the first groove 121A; the step surface 121 is recessed to form a second groove 121B, the first grooves 121A are connected end to end and are arranged around the axis of the first installation frame 10, and the first groove 121A is located on the inner side of 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 installation frame 10, and the other end of the rotating member 30 away from the first groove 121A is rotatably arranged on the first horizontal member 411; the slider 412 is arranged on the side of the first horizontal member 411 facing the step surface 121, and is located in the second groove 121B.

[0055] It can be understood that 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 along the first groove 121A and the second groove 121B at the same time to rotate around the axis of the first installation frame 10, thereby allowing the rotating member 30 to rotate more smoothly around the axis of the first installation frame 10.

[0056] In the present technical solution, the first groove 121A is provided so that the rotating member 30 can revolve around the axis of the first installation frame 10 along the extension direction of the first groove 121A, and the structure is simple and easy to implement. At the same time, the first horizontal member 411 and the slider 412 are provided so that when the rotating member 30 revolves around the axis of the first installation frame 10, the first horizontal member 411 and the slider 412 can revolve around the axis of the first installation frame 10 together, so as 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 installation frame 10.

[0057] According to some embodiments of this application, please refer to Figure 1 and Figure 2 , and please refer to Figure 5-Figure 7The McWheel-type pier laminating machine also includes an inner gear 13, an insert block 417, a switching assembly 416 and a second gear 14. The inner gear 13 is rotatably arranged on the inner wall of the second part 12, and a third groove 131 is arranged at one end of the inner gear 13 facing the first part 11 along the third direction Z, and the third direction Z is parallel to the axis of the first installation frame 10; the insert block 417 is slidably arranged at one end of the first horizontal member 411 away from the rotating member 30 along the third direction Z, and the third groove 131 is adapted to the insert block 417, and the insert block 417 has a first position and a second position. In the first position, one end of the insert block 417 is located in the third groove 131, and in the second position, the insert block 417 leaves the third groove 131; the switching assembly 416 is used to drive the insert block 417 to switch between the first position and the second position; the second gear 14 is detachably connected to the climbing wheel 22, and the second gear 14 is meshed with the inner gear 13.

[0058] Specifically, when the device climbs to coat the pier, the second drive member 23 may not work at this time, and the insertion block 417 may be driven to the first position through the switching component 416, so that the first drive member can drive the internal gear 13 to rotate through the insertion block 417 when driving the first horizontal member 411 to rotate around the axis of the first mounting frame 10, thereby driving the second gear 14 and the climbing wheel 22 to rotate. Therefore, the number of revolutions of the climbing wheel 22 when the film is wound around the pier can be adjusted by adjusting the tooth ratio of the second gear 14 and the internal gear 13, thereby roughly adjusting the distance that the first installation frame 10 moves along the extension direction of the pier. On the one hand, the protective film can cover the pier more evenly. On the other hand, the above adjustment can make the rotation direction of the outer periphery of the climbing wheel 22 tangent to the extension direction of the protective film abutting the outer periphery, thereby further reducing the risk of wrinkling of the protective film. When the device descends to continue coating the pier, the switching assembly 416 can be used to drive the insertion block 417 to the second position, so that when the first driving member drives the first horizontal member 411 to rotate around the axis of the first installation frame 10, it will not interfere with the second driving member 23 driving the climbing wheel 22 to rotate to drive the first installation frame 10 to descend.

[0059] According to some embodiments of this application, please refer to Figure 1 There are multiple third grooves 131 arranged at intervals along the circumference of the first installation frame 10.

[0060] In the present technical solution, a plurality of third grooves 131 are arranged at intervals along the circumference of the first installation frame 10 to facilitate the insertion of the insertion block 417 .

[0061] According to some embodiments of this application, please refer to Figure 1 and Figure 2 , and please refer to Figure 5-Figure 7The switching assembly 416 includes a third driving member 4161, a second guide rod 4162244 and a third elastic member 4163. The third driving member 4161 is arranged on the first horizontal member 411, and a mounting block is arranged at the output end of the third driving member 4161, and the third driving member 4161 is used to drive the mounting block to move along the third direction Z; one end of the second guide rod 4162244 is connected to the insertion block 417, and the mounting block has a guide hole on the side facing the inner gear 13, and the other end of the second guide rod 4162244 can be inserted in the guide hole to move along the third direction Z; the third elastic member 4163 is sleeved outside the second guide rod 4162244, and the two ends of the third elastic member 4163 are respectively abutted against the insertion block 417 and the mounting block.

[0062] The third elastic member 4163 may be a spring. Exemplarily, the third elastic member 4163 may be a compression spring.

[0063] The third driving member 4161 may be a cylinder or an electric telescopic rod.

[0064] Specifically, the third driving member 4161 drives the mounting block to move along the third direction Z. When the insertion block 417 can be directly inserted into the third groove 131, the mounting block can drive the second guide rod 4162244, the third elastic member 4163 and the insertion block 417 to move along the third direction Z. When the insertion block 417 can abut against the non-third groove 131 area of ​​the internal gear 13, the mounting block compresses the third elastic member 4163, so that when the insertion block 417 can be directly inserted into the third groove 131, the elastic force provided by the third elastic member 4163 enables the insertion block 417 to be inserted into the third groove 131.

[0065] According to some embodiments of this application, please refer to Figure 5 , Figure 7 and Figure 8 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 arranged on the first horizontal member 411, and the rotation axis of the second horizontal member 413 is parallel to the axis of the first installation frame 10; the movable rod 414 is arranged at one end of the second horizontal member 413 away from the axis of the second horizontal member 413 close to the first installation frame 10, and extends along the axis of the first installation frame 10, and the movable rod 414 is used to be inserted into the film roll; the two ends of the first elastic member 415 are respectively arranged 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 toward the direction close to the first horizontal member 411.

[0066] The axis of the movable rod 414 is parallel to the third direction Z.

[0067] In some embodiments, a tray 4131 is disposed at one end of the second horizontal member 413 . The tray 4131 is disposed at one end of the movable rod 414 so as to abut against the film roll along the third direction Z.

[0068] The first elastic member 415 may be a spring. For example, the first elastic member 415 may be a tension spring.

[0069] It can be understood that when the pier is non-cylindrical, such as rectangular or square, the direction of the tensile force on the membrane roll will change when it passes around the edge of the pier, causing the membrane roll to be stuck in a short period of time. At this time, the membrane roll continues to rotate around the pier, causing the tensile force on the protective film to increase, which in turn causes the protective film to break. By setting the second horizontal member 413, the movable rod 414 and the membrane roll can rotate in the direction close to the edge of the pier to reduce the distance between the membrane roll and the edge, thereby reducing the tensile force on the protective film and reducing the risk of the protective film breaking. During this period, the first elastic member 415 is stretched, and then the first elastic member 415 is shortened to drive the second horizontal member 413 to reset.

[0070] In the present technical solution, a first elastic member 415 is arranged between the second horizontal member 413 and the first horizontal member 411, so that when the movable component 41 drives the film winding pier to rotate, when the film roll itself is stuck in rotation, the second horizontal member 413 can be rotated relative to the first horizontal member 411, so as to reduce the risk of untimely film discharge due to the jamming of the film roll itself, and thus causing the risk of the protective film to break; and when the film roll itself resumes its rotation, the first elastic member 415 can drive the second horizontal member 413 structure to reset.

[0071] According to some embodiments of this application, please refer to Figure 5 The first horizontal member 411 includes a shell 4111 and a connecting rod 4112; the other end of the rotating member 30 away from the first groove 121A is rotatably arranged at the end of the shell 4111 facing the step surface 121, and the peripheral side of the shell 4111 has a strip hole 4111A for the second horizontal member 413 to pass through, and the strip hole 4111A extends along the circumference of the shell 4111, and one end of the second horizontal member 413 is rotatably arranged in the shell 4111; the connecting rod 4112 is arranged on the outer peripheral side of the shell 4111 and extends along the radial direction of the first mounting frame 10, and the slider 412 is arranged on the side of the connecting rod 4112 facing the step surface 121.

[0072] 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 around its own axis.

[0073] In the present technical solution, a strip hole 4111A is provided on the circumferential side of the shell 4111 for the second horizontal piece 413 to pass through, and the strip hole 4111A is extended along the circumference of the shell 4111 so that the second horizontal piece 413 can rotate along the circumference of the shell 4111, and the strip hole 4111A can limit the rotation range of the second horizontal piece 413, so as to reduce the risk of plastic deformation of the first elastic piece 415 caused by excessive rotation of the second horizontal piece 413.
