It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] Device Embodiment:

[0022] Refer to Figures 1 to 2 , which shows the preferred structure of the pier column formwork climbing device in this embodiment. As shown in the figure, the pier column formwork climbing device includes: a climbing rod 1, a power driving mechanism 2, and a climbing body 3. Among them, the climbing rod 1 is used to be arranged on one side of the pier column. Specifically, the climbing rod 1 is vertically arranged on one side of the pier column, and the height direction of the climbing rod 1 ( Figure 1 the direction from top to bottom as shown) is consistent with the height direction of the pier column.

[0023] The climbing body 3 is movably arranged on the climbing rod 1, and the climbing body 3 is connected to the pier column formwork. Specifically, the climbing body 3 is a box structure with a hollow interior, and the climbing rod 1 is movably inserted through the climbing body 3. Then, the climbing rod 1 passes through the interior of the climbing body 3 from the bottom of the climbing body 3 and then passes through the top of the climbing body 3. The climbing body 3 is arranged at the bottom of the support frame of the pier column formwork, so that the climbing body 3 is relatively fixed to the pier column formwork.

[0024] The power driving mechanism 2 is arranged on the climbing body 3, and the power driving mechanism 2 is used to drive the climbing body 3 to move along the height direction of the climbing rod 1 by using electric power. Since the climbing body 3 is arranged at the bottom of the support frame of the pier column formwork, the movement of the climbing body 3 drives the pier column formwork to move together.

[0025] During use, the climbing rod 1 is arranged on one side of a completed pier column section, the climbing body 3 is connected to the bottom of the support frame of the pier column formwork, and the power driving mechanism 2 drives the climbing body 3 to move upward along the climbing rod 1, thereby driving the pier column formwork to move upward together, so that the pier column formwork moves above the completed pier column, and concrete is poured into the pier column formwork to form another pier column section.

[0026] It can be seen that in this embodiment, the climbing rod 1 is arranged on one side of the pier column. The climbing body 3 is movably arranged on the climbing rod 1 and connected to the pier column formwork. The electric drive mechanism 2 drives the climbing body 3 to move along the climbing rod 1, thereby driving the movement of the pier column formwork and realizing the climbing of the pier column formwork. The device has a simple structure and is easy to install. Moreover, the electric drive mechanism 2 uses electricity to drive the climbing body 3, avoiding the problem in the prior art that the formwork drops due to oil leakage, pipe explosion, etc. in the hydraulic system, improving the stability and safety of the formwork climbing, and solving the problems in the prior art that it is not easy to install the high pier column formwork by using the hydraulic climbing formwork and the formwork is prone to dropping.

[0027] See Figures 1 to 2 , in the above embodiment, the electric drive mechanism 2 includes: a drive motor 21 and a transmission mechanism. Among them, the drive motor 21 is arranged outside the climbing body 3, and the drive shaft of the drive motor 21 rotatably penetrates through the bottom wall of the climbing body 3 ( Figure 1 the lower wall shown), and a part of the drive shaft of the drive motor 21 is placed inside the climbing body 3. Specifically, the drive motor 21 is placed at the bottom outside the climbing body 3, and the drive shaft of the drive motor 21 is connected to the bottom wall of the climbing body 3 through a bearing. More specifically, a through hole is opened on the bottom wall of the climbing body 3, a bearing is arranged in the through hole, and the drive shaft of the drive motor 21 is connected to the bearing, so that the drive shaft can rotate freely.

[0028] The transmission mechanism is arranged inside the climbing body 3, the transmission mechanism is connected to the part of the drive shaft placed inside the climbing body 3, and the transmission mechanism is connected to the climbing rod 1. The transmission mechanism is used to convert the rotation of the drive shaft into the movement of driving the climbing body 3 along the climbing rod 1. Specifically, the drive shaft of the drive motor 21 is arranged in parallel with the climbing rod 1 inside the climbing body 3, and the transmission mechanism transmits the rotation of the drive shaft to between the climbing body 3 and the climbing rod 1, so that the climbing body 3 moves along the climbing rod 1.

[0029] The transmission mechanism includes: a first gear and a second gear 22. Among them, the first gear is arranged on the part of the drive shaft placed inside the climbing body 3. Specifically, the first gear is sleeved on the part of the drive shaft placed inside the climbing body 3, and the inner ring of the first gear is fixedly connected to the drive shaft.

[0030] The outer wall of the climbing rod 1 is provided with threads.

[0031] The second gear 22 is rotatably arranged in the climbing body 3, that is, the second gear 22 is rotatably connected to the bottom wall in the climbing body 3. Moreover, the inner ring of the second gear 22 is screwed to the climbing rod 1, and the outer ring of the second gear 22 meshes with the first gear. Specifically, the inner ring of the second gear 22 is provided with threads, the second gear 22 is sleeved on the climbing rod 1, and the second gear 22 is screwed to the climbing rod 1. The meshing teeth on the outer ring of the second gear 22 mesh with the meshing teeth on the outer ring of the first gear. In this way, when the drive shaft of the drive motor 21 rotates, it drives the first gear to rotate, and then drives the rotation of the second gear 22. Since the second gear 22 is screwed to the climbing rod 1 and the climbing rod 1 is fixed, the rotation of the second gear 22 drives the second gear 22 to move along the climbing rod 1. Since the second gear 22 is rotatably connected to the bottom wall in the climbing body 3, the movement of the second gear 22 along the climbing rod 1 drives the climbing body 3 to move along the climbing rod 1, and then drives the pier formwork to move.

[0032] Preferably, a baffle 6 is arranged at the top of the climbing rod 1. The radial dimension of the baffle 6 is larger than the diameter of the climbing rod 1. In this way, the baffle 6 limits the climbing body 3 to prevent the climbing body 3 from detaching from the top of the climbing rod 1.

[0033] A through hole is formed in the baffle 6, and this through hole is used to connect with the hanging plate at the pier. Specifically, the hanging plate is arranged at the top of the completed pier, and the hanging plate is perpendicular to the pier. The hanging plate and the baffle 6 are connected by bolts and nuts. That is, two connecting ears are arranged on the hanging plate, and through holes are formed at the corresponding positions of the two connecting ears. The baffle 6 is placed between the two connecting ears of the hanging plate, and the through hole of the baffle 6 corresponds to the through holes on the two connecting ears. The bolts are passed through the through hole and the two through holes and then connected with the nuts, so as to position the climbing rod 1.

[0034] Preferably, the pier formwork climbing device further includes: a connecting cylinder 7. Among them, the connecting cylinder 7 is placed outside the climbing body 3 and at the bottom of the climbing body 3. The side wall of the connecting cylinder 7 is connected to the drive motor 21, that is, the connecting cylinder 7 is relatively fixed to the drive motor 21, and the connecting cylinder 7 is slidably passed through the climbing rod 1. In this way, when the drive motor 21 moves along the climbing rod 1 together with the climbing body 3, the connecting cylinder 7 also moves along the climbing rod 1 together with the drive motor 21.

[0035] In specific implementation, the first gear is a small gear, and the second gear 22 is a large gear, and speed reduction is achieved through the meshing of the small gear and the large gear.

[0036] In this embodiment, the length of the climbing rod 1 is 6m, and the stroke of the climbing rod 1 is 5.8m. The drive motor 21 uses a motor with 3.2KW and a rated maximum thrust of 500KN.

[0037] It can be seen that in this embodiment, the electric drive mechanism 2 drives the first gear to rotate through the drive shaft of the drive motor 21, and then drives the second gear 22 to rotate, causing the second gear 22 to move along the climbing rod 1, and further driving the entire climbing body 3 to move along the climbing rod 1, thereby driving the pier formwork to move along the climbing rod 1. The structure is simple and easy to implement. Moreover, the climbing speed is stable and the vibration is small.

[0038] Regarding the structure at the drive shaft and the first gear, this embodiment shows an implementation manner: the pier formwork climbing device further includes: a gasket 4 and a nut 5. Among them, the end of the drive shaft placed inside the climbing body 3 is provided with a thread, and the nut 5 is screwed with the thread at the end of the drive shaft.

[0039] The gasket 4 is sleeved on the drive shaft. Specifically, the gasket 4 is provided with a through hole, and the drive shaft is passed through the through hole on the gasket 4. Moreover, the gasket 4 is placed between the nut 5 and the first gear. Specifically, the gasket 4 can be in contact with the first gear, or the gasket 4 is fixed to the drive shaft, and there is a certain gap between the gasket 4 and the first gear.

[0040] Regarding the structure at the drive shaft and the first gear, this embodiment shows another implementation manner: the pier formwork climbing device further includes: a positioning plate (not shown in the figure) and a plurality of support columns (not shown in the figure). Among them, the positioning plate is placed inside the climbing body 3, and the positioning plate is parallel to the bottom wall of the climbing body 3. There is a certain distance between the positioning plate and the bottom wall of the climbing body 3, and the positioning plate is connected to the bottom wall of the climbing body 3 through each support column.

[0041] The part of the drive shaft placed inside the climbing body 3 is rotatably connected to the positioning plate. Specifically, the positioning plate is provided with a through hole, and a connecting bearing is arranged inside the through hole. The drive shaft is connected to the connecting bearing. The end of the drive shaft is placed above the positioning plate (that is, the end of the drive shaft extends to the top wall of the climbing body 3), and a positioning body is arranged at this end of the drive shaft. The outer diameter of the positioning body is larger than the aperture of the through hole. In this way, the positioning body can position the end of the drive shaft, making the drive shaft stably and rotatably connected to the positioning plate.

[0042] The first gear is placed between the bottom wall of the climbing body 3 and the positioning plate.

[0043] During specific implementation, each component in the pier formwork climbing device is made of steel.

[0044] In summary, in this embodiment, the climbing rod 1 is arranged on one side of the pier column. The climbing body 3 is movably arranged on the climbing rod 1 and connected to the pier column formwork. The electric driving mechanism 2 drives the climbing body 3 to move along the climbing rod 1, thereby driving the pier column formwork to move and realizing the climbing of the pier column formwork. The device has a simple structure and is easy to install. Moreover, the electric driving mechanism 2 is used to drive the climbing body 3 by electricity, avoiding the falling of the formwork caused by oil leakage, pipe explosion, etc. in the prior art using a hydraulic system, and improving the stability and safety of the formwork climbing.

[0045] Method embodiment:

[0046] This embodiment also proposes a climbing method using the above-mentioned pier column formwork climbing device. Refer to Figure 3 , and this method includes the following steps:

[0047] Climbing rod installation step S1: Install the climbing rod on one side of the pier column and install a hanging plate on the pier column.

[0048] Specifically, the pier column is a completed pier column. During the pouring process of the pier column, climbing cones are embedded. When the concrete strength reaches the design strength, it means that the pier column is completed. After the pier column is poured, the climbing rod 1 is placed on one side of the pier column, and the height of the climbing rod 1 is consistent with the height of the pier column. The hanging plate is detachably arranged at the top of the pier column. The hanging plate is perpendicular to the side of the pier column facing the climbing rod 1, and moreover, the hanging plate is also perpendicular to the climbing rod 1. More specifically, the embedded climbing cones are arranged at the top of the pier column. The first end of the hanging plate is detachably connected to the embedded climbing cone, and the second end of the hanging plate corresponds to the top of the climbing rod 1.

[0049] Specifically, during implementation, the hanging plate and the embedded climbing cone are connected by high-strength bolts.

[0050] Connection step S2: Connect the hanging plate to the climbing rod.

[0051] Specifically, refer to Figures 1 to 2 , a baffle 6 is arranged at the top of the climbing rod 1, and a through hole is opened on the baffle 6. Two connecting ears are arranged side by side at the second end of the hanging plate, and openings are opened at the corresponding positions of the two connecting ears. The baffle 6 is placed between the two connecting ears of the hanging plate. The through hole of the baffle 6 corresponds to the openings on the two connecting ears. A bolt passes through the through hole and the two openings and is connected to a nut 5, so that the hanging plate is fixed to the top of the climbing rod 1, that is, the climbing rod 1 is positioned.

[0052] In this embodiment, the hanging plate can be a Q225 steel plate.

[0053] Pier column formwork climbing step S3: Connect the pier column formwork to the climbing body, and the electric driving mechanism drives the climbing body to move upward along the climbing rod, driving the pier column formwork to move to the designed position.

[0054] Specifically, refer to Figures 1 to 2 , connect the climbing body 3 to the bottom of the support frame of the pier formwork. In this way, the overall weight of the pier formwork and the support frame is transmitted to the hanging plate through the climbing body 3 and the climbing rod 1, and finally transmitted to the pier.

[0055] When the driving shaft of the driving motor 21 in the electric driving mechanism 2 rotates, it drives the first gear to rotate. Since the first gear meshes with the second gear 22, the rotation of the first gear drives the rotation of the second gear 22. Since the second gear 22 is screwed to the climbing rod 1 and the climbing rod 1 is fixed, the rotation of the second gear 22 drives the second gear 22 to move along the climbing rod 1, thereby driving the climbing body 3 to move along the climbing rod 1, and further driving the pier formwork to move until the pier formwork moves to the designed position. At this time, both the climbing body 3 and the pier formwork are placed at the top or near the top of the climbing rod 1.

[0056] Hoisting rod installation step S4: Install the hoisting rod on the pier formwork and connect the hoisting rod to the hanging plate.

[0057] Specifically, connect the hoisting rod and the hanging plate by bolts. In this way, the weight of the pier formwork and the support frame is transferred to the pier.

[0058] Climbing body climbing step S5: Disconnect the connection between the hanging plate and the climbing rod, and the electric driving mechanism drives the climbing rod to move upward to the designed position of the upper section of the pier.

[0059] Specifically, refer to Figures 1 to 2 , after connecting the hoisting rod and the hanging plate, remove the bolts and nuts 5 between the hanging plate and the climbing rod 1. When the driving shaft of the driving motor 21 in the electric driving mechanism 2 rotates, it drives the first gear to rotate. Since the first gear meshes with the second gear 22, the rotation of the first gear drives the rotation of the second gear 22. Since the second gear 22 is screwed to the climbing rod 1 and the pier formwork is connected to the hanging plate through the hoisting rod, the pier formwork is fixed, so the climbing body 3 is also fixed. Therefore, the rotation of the second gear 22 drives the climbing rod 1 to move upward until the climbing rod 1 moves to the designed position of the upper section of the pier. At this time, both the climbing body 3 and the pier formwork are placed at the bottom of the climbing rod 1.

[0060] Pouring step S6: Pour concrete into the pier formwork to form the upper section of the pier, and install the hanging plate on the upper section of the pier.

[0061] Specifically, pour concrete into the pier formwork, so that a section of the pier is poured on the completed pier in the climbing rod installation step S1. If the completed pier in the climbing rod installation step S1 is regarded as the first section of the pier, then the upper section of the pier formed in the pouring step S6 is the second section of the pier, and the hanging plate is installed at the top of the second section of the pier.

[0062] Repeat the connection step S2, the pier column formwork climbing step S3, the suspender installation step S4, the climber climbing step S5, and the pouring step S6 in sequence to form multiple sections of pier columns.

[0063] Specifically, connect the hanging plate at the top of the second section of the pier column to the top of the climbing rod that climbs to the designed position of the previous section of the pier column in the climber climbing step S5. Then, remove the bolts between the suspender and the hanging plate at the top of the first section of the pier column. The electric drive mechanism drives the climber to move upward along the climbing rod, driving the pier column formwork to move upward to the designed position of the third section of the pier column. Then, install a suspender on the pier column formwork. The suspender is connected to the hanging plate at the top of the second section of the pier column by bolts. Disconnect the connection between the hanging plate at the top of the second section of the pier column and the climbing rod. The electric drive mechanism drives the climbing rod to move upward to the designed position of the third section of the pier column. Pour concrete into the pier column formwork to form the third pier column, and repeat the above operations to form multiple sections of pier columns.

[0064] For the specific implementation process of the pier column formwork climbing device, refer to the above description, and it will not be elaborated in this embodiment.

[0065] It can be seen that in this embodiment, a climbing rod is installed on one side of the pier column and connected to the climbing rod through a hanging plate to position the climbing rod. The electric drive mechanism drives the climber to move along the climbing rod, thereby driving the pier column formwork to move upward to the designed position. Then, the pier column formwork is connected to the hanging plate through a suspender to position the pier column formwork and the climber. Disconnect the connection between the hanging plate and the climbing rod. The electric drive mechanism drives the climbing rod to move upward to the designed position of the previous section of the pier column. Pour concrete into the pier column formwork, so as to pour the upper section of the pier column on the completed pier column. Install a hanging plate on the upper section of the pier column and repeat the above steps to form multiple sections of pier columns. This method is simple in operation and easy to implement. Moreover, the electric drive mechanism is used to drive the climber and the climbing rod by electricity, avoiding the falling of the formwork caused by oil leakage, pipe explosion, etc. in the prior art using a hydraulic system, and improving the stability and safety of the formwork climbing.
