[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] In some of these embodiments, such as Figures 1 to 8 As shown, this application proposes an automatic climbing concrete cylindrical pier climbing platform, including an upper clamping mechanism 100, a lower clamping mechanism 200, a lifting cylinder 300, and a pouring clamping mechanism 400. The upper clamping mechanism 100 refers to a frame structure containing an openable clamping clamp, specifically implemented by combining a hinged semi-circular clamp with a locking cylinder, used to alternately clamp the pier column during the climbing process. The lower clamping mechanism 200 refers to a clamping device corresponding to the upper clamping mechanism 200, achieving the alternating locking function through the same working principle. The lifting cylinder 300 refers to a hydraulic actuator providing vertical power, specifically implemented by a double-acting hydraulic cylinder, whose stroke control accuracy directly affects the platform's climbing step distance. The pouring clamping mechanism 400 refers to an independent locking device located at the top, specifically employing a split clamping structure, providing rigid fixation required for the pouring operation after the platform is in position.

[0038] Specifically, the structural relationship between the upper clamping mechanism 100, the lower clamping mechanism 200, the lifting cylinder 300, and the casting clamping mechanism 400 is as follows: the upper clamping mechanism 100 and the lower clamping mechanism 200 are arranged vertically and connected to each other by the vertically arranged lifting cylinder 300, so as to alternately clamp the cylindrical pier and cooperate with the lifting cylinder 300 to move up and down. The casting clamping mechanism 400 is installed on top of the upper clamping mechanism 100 to lock the cylindrical pier. In the initial state, the lower clamping mechanism 200 clamps the pier through the locking cylinder, and the upper clamping mechanism 100 is in a loose state. The lifting cylinder 300 extends and pushes the upper clamping mechanism 100 upward. After reaching the predetermined stroke, the upper clamping mechanism 100 locks the pier. Then the lower clamping mechanism 200 releases the clamp, and the lifting cylinder 300 retracts, driving the lower clamping mechanism 200 to rise. This alternating action is repeated to achieve continuous platform climbing. When the platform reaches the target height, the top pouring clamp 400 mechanism is used to lock the pier column, forming a stable concrete pouring working surface.

[0039] This climbing platform replaces traditional hoisting and positioning with mechanical alternating clamping, eliminating positioning errors caused by dependence on hoisting equipment. The coordinated control of the double clamping mechanisms 100 and 200 with the lifting cylinder 300 enables the construction platform to self-drive its ascent, reducing the need for manual operation at height. This alternating climbing mechanism reduces the frequency of manual fixed-position work at height, significantly improving construction safety. The self-drive climbing function allows the platform to adapt to the construction needs of piers of different heights, increasing equipment reuse rate.

[0040] like Figures 1 to 5 As shown, this application further proposes an upper clamping mechanism 100 including an upper frame 101, an upper climbing clamp 102, and an upper locking cylinder 103. The upper frame 101 refers to the steel structure support that bears the clamp assembly. Specifically, it can be implemented by welding I-beams to form a rectangular frame. The hinge holes at its front and rear ends form a rotating pair connection with the end of the piston rod of the lifting cylinder, providing a rigid support foundation for the clamp opening and closing action. The upper climbing clamp 102 refers to a circumferential constraint device composed of two symmetrically distributed arc-shaped components. The ear plates at the left and right ends form an adjustable connection with the piston rod of the locking cylinder, and the opening and closing diameter of the clamp is controlled by the extension and retraction of the cylinder. The upper locking cylinder 103 refers to a hydraulic actuator that provides radial clamping force. The synchronous extension and retraction of the cylinders on both sides can ensure that a uniform circumferential pressure is formed on the cylindrical pier when the clamp is closed.

[0041] Specifically, the upper frame 101 is equipped with an upper climbing clamp 102, the front and rear ends of which are hinged to the lower ends of the lifting cylinder 300. The upper climbing clamp 102 is fitted onto the cylindrical pier and consists of two opposing upper semicircular clamps. The left and right ends are connected by upper locking cylinders 103 for opening and closing. The upper frame 101 is connected to the lifting cylinder 300 by hinges to form a rotatable support structure. The two upper semicircular clamps are initially in the open position. The synchronous contraction of the upper locking cylinders 103 on both sides drives the clamps to close towards the surface of the cylindrical pier. When the cylinder stroke ends, the inner wall of the clamp makes surface contact with the pier surface. During the locking process, the horizontal thrust generated by the symmetrically arranged double cylinders causes the two clamps to move synchronously in the radial direction, eliminating the eccentric loading phenomenon caused by unilateral force application. The complete ring structure formed after the clamps are closed can evenly transmit the locking force to the pier surface, avoiding local stress concentration and damage to the concrete surface.

[0042] Furthermore, such as Figure 2 and Figure 4 As shown, this application further proposes that lifting guide rods 104 are respectively provided at the four corners of the bottom of the upper frame 101. The lifting guide rods 104 refer to four rod-shaped structures that are vertically installed at the bottom of the upper frame 101. Specifically, they can be hollow steel pipes or solid steel bars. Their outer diameter forms a clearance fit with the lifting guide tube 204 of the lower frame 201 to limit the horizontal displacement of the upper frame 101 during the lifting process.

[0043] When in use, when the lifting cylinder 300 drives the upper frame 101 to rise, the lifting guide rods 104 at the four corners are inserted into the corresponding lifting guide tubes 204 of the lower frame 201, forming a four-point rigid guide structure, so that the upper frame 201 can only move in the vertical direction, eliminating the frame offset caused by horizontal swaying.

[0044] Furthermore, such as Figure 2 and Figure 6 As shown, this application further proposes that the upper frame 101 has upper clamp guide grooves 106 on both the front and rear sides; each upper semicircular clamp has an upper clamp guide rod 105 on its back that cooperates with the upper clamp guide groove 106. The upper clamp guide groove 106 refers to an elongated groove extending along the front and rear direction of the upper frame, which can be installed on the front and rear sides of the upper frame by welding or bolting, to constrain the horizontal sliding trajectory of the upper clamp guide rod 105 and prevent radial displacement during the opening and closing of the clamp. The upper clamp guide rod 105 refers to a square rod fixed to the back of the upper semicircular clamp, which can be made of steel pipe matching the width of the groove, and its end is embedded in the upper clamp guide groove 106 to guide the two semicircular clamps to open and close synchronously along a predetermined path.

[0045] In use, when the upper locking cylinder 303 drives the two upper semi-circular clamps to close, the upper clamp guide rod 105 fixed to the back of the clamp slides horizontally along the upper clamp guide groove 105, forcing the two clamps to move symmetrically along the length of the groove. This ensures uniform contact between the inner wall of the clamp and the surface of the cylindrical pier, preventing clamp locking failure due to unilateral jamming. The synergistic effect of the lifting guide rod 105 and the guide groove 106 eliminates the mechanical interference between the frame lifting and clamp opening / closing actions, achieving independent control of the lifting process and the locking action.

[0046] like Figures 1 to 5 As shown, this application further proposes a lower clamping mechanism 200 including a lower frame 201, a lower climbing clamp 202, and a lower locking cylinder 203. The lower frame 201 refers to the main support structure of the lower clamping mechanism 200, specifically it can be welded from a steel frame, used to support the lower climbing clamp 202 and hinged to the top of the lifting cylinder 300, so that the lower frame 201 can move up and down with the extension and retraction of the cylinder. The lower climbing clamp 202 is a ring-shaped clamping component composed of two lower semi-circular clamps. The extension and retraction of the lower locking cylinder 203 controls the opening and closing of the clamp, realizing contact or separation with the surface of the cylindrical pier. Similar to the upper locking cylinder 103, the lower locking cylinder 203 is a hydraulic actuator that provides radial clamping force. The synchronous extension and retraction of the cylinders on both sides can ensure that a uniform circumferential pressure is formed on the cylindrical pier when the clamp is closed.

[0047] The lower frame 201 is equipped with a lower climbing clamp 202, and its front and rear ends are respectively hinged to the top of the lifting cylinder 300. The lower climbing clamp 202 is fitted onto the cylindrical pier and consists of two opposing lower semi-circular clamps. The left and right ends are connected by lower locking cylinders 203 for opening and closing. The split design of the lower semi-circular clamps divides the lower climbing clamp 202 into two symmetrical parts. The lower locking cylinders 203 at both ends drive the synchronous opening and closing action to ensure uniform contact between the clamp and the pier surface, so that the lower clamp mechanism 200 is in a fixed state.

[0048] When the locking cylinder 203 retracts, the two lower semi-circular clamps separate outwards, releasing the constraint. At this time, the lower frame 201 can freely rise and fall with the movement of the lifting cylinder 300. By alternately controlling the locking and unlocking states of the upper and lower clamp mechanisms 100 and 200, in conjunction with the extension and retraction movement of the lifting cylinder 300, the climbing platform can be gradually raised. The hinged connection at the upper and lower ends of the lifting cylinder 300 allows the upper and lower frames to adapt to the slight tilt or unevenness of the pier during the lifting process, avoiding jamming or uneven loading problems caused by rigid connections.

[0049] Furthermore, such as Figure 2 and Figure 4As shown, this application further proposes that lifting guide tubes 204 are respectively provided at the four corners of the lower frame 201 to cooperate with the lifting guide rods 104 at the four corners of the bottom of the upper clamping mechanism 100. The lifting guide tubes 204 refer to hollow tubular structures provided at the four corners of the lower frame 201. Specifically, they can be steel pipes with an inner diameter slightly larger than the outer diameter of the lifting guide rods 104, which are used to nest the lifting guide rods 104 during the lifting process to limit horizontal displacement.

[0050] Furthermore, such as Figure 2 and Figure 6 As shown, lower clamp guide grooves 206 are provided on both the front and rear sides; and each lower semicircular clamp has a lower clamp guide rod 205 on its back that mates with the lower clamp guide groove 206. The lower clamp guide groove 206 refers to an elongated groove extending along the front-rear direction of the lower frame 201, which can be installed on the front and rear sides of the upper frame by welding or bolting, providing a sliding path for the lower clamp guide rod 205. The lower clamp guide rod 205 refers to a columnar component fixed to the back of the lower semicircular clamp, used to slide along the lower clamp guide groove 206 to constrain the opening and closing trajectory of the clamp.

[0051] The cooperation between the lower clamp guide groove 206 and the lower clamp guide rod 205 guides the two lower semi-circular clamps to close synchronously towards the center or expand outward under the drive of the lower locking cylinder 202, ensuring that the clamps do not rotate or misalign during opening and closing. During the lifting phase, the lifting guide tube 204 continuously wraps around the lifting guide rod 104, eliminating relative sway between the frames through the surface contact between the tube wall and the rod body; during the clamp locking phase, the horizontal movement of the lower clamp guide rod 205 along the lower clamp guide groove 206 keeps the contact surface of the two lower semi-circular clamps perpendicular to the axis of the cylindrical pier, thereby improving the concentricity of the clamps when they close.

[0052] Furthermore, it is worth noting that, such as Figure 2 , Figure 4 and Figure 6 As shown, this application further proposes that the bottom of the lower frame 201 is provided with a number of spaced support feet 207. The support feet 207 refer to load-bearing structures that are spaced along the bottom of the lower frame. Specifically, they can be fixed to the bottom of the lower frame 201 by welding or bolting to distribute the platform load to the ground.

[0053] As needed, height-adjustable bolt assemblies 208 can be installed on each support foot 207. The height-adjustable bolt assembly 208 refers to the threaded adjustment mechanism installed on the support foot 207. Specifically, a conventional screw structure with a locking nut can be used. The height of the support foot can be independently adjusted by rotating the screw to compensate for uneven ground.

[0054] As needed, this application further proposes that the lower frame 201 has an equipment installation platform 209 provided on one side of the support leg 207. The equipment installation platform 209 refers to the load-bearing plane integrated on the side of the support leg, which can be formed by welding steel plates, and is used to fix construction equipment or tools to prevent the equipment from shaking or slipping during high-altitude operations.

[0055] like Figure 3 and Figure 4 As shown, this application further proposes that the lifting cylinders 300 be in two or four sets, symmetrically installed on the upper frame of the upper clamping mechanism 100 and the lower frame of the lower clamping mechanism 200 in a front-to-back and / or left-to-right manner. Two or four sets refer to the fact that the number of lifting cylinders 300 can be flexibly configured according to actual load requirements. For example, two sets of cylinders can be used under light load conditions, while four sets of cylinders can be used under heavy load conditions or in scenarios requiring higher stability. Specifically, a hydraulic synchronous control system can be used to achieve synchronous extension and retraction of multiple sets of cylinders, ensuring balanced output of each cylinder during lifting. For example, two sets of lifting cylinders 300 can be symmetrically arranged in the front-to-back direction, and four sets of lifting cylinders 300 can be symmetrically arranged simultaneously in the front-to-back and left-to-right directions. Specifically, the cylinders can be symmetrically connected to the upper and lower frames through hinge points on the frames, so that the lifting driving force forms a symmetrical vector distribution in the horizontal plane.

[0056] like Figures 1 to 4 and Figure 7 As shown, this application further proposes a casting clamp mechanism 400 including a casting support frame 401 and a locking clamp 402. The casting support frame 401 refers to a rigid frame structure that supports the locking clamp 402, which can be implemented using welded steel beams or bolted steel sections, and is used to transfer the load of the locking clamp to the upper clamp mechanism 100. The locking clamp 402 is a circumferential constraint device composed of two symmetrically distributed arc-shaped components. The ear plates at the left and right ends are connected by bolts or hydraulic cylinders to form an adjustable connection to control the opening and closing diameter of the clamp.

[0057] Specifically, the casting support frame 401 is fixedly installed on the top of the upper frame 101 of the upper clamping mechanism 100, and a locking clamp 402 is movably installed inside it. The locking clamp 402 is sleeved on the cylindrical pier and consists of two oppositely arranged locking semi-circular clamps. The left and right ends are connected by locking cylinders or high-strength bolts. The casting support frame 401 is fixed to the top of the upper frame 201 by bolts to form a rigid connection, and the movable installation of the locking clamp 402 allows it to be adjusted radially along the internal space of the support frame 401.

[0058] When the two locking semicircular clamps of locking clamp 402 are in the open state, their inner diameter is larger than the diameter of the cylindrical pier to facilitate position adjustment. During the closing process, the two semicircular clamps are pushed to retract synchronously along the guide structure by a locking cylinder, or the clamps are closed by applying axial tension through high-strength bolts. After the clamps are closed, their inner walls form surface contact with the surface of the cylindrical pier, and axial fixation is achieved through friction.

[0059] Furthermore, such as Figure 7 As shown, this application further proposes that casting support frame 401 be provided with casting clamp guide grooves 404 on both the front and rear sides, and each locking semicircular clamp is provided with a locking clamp guide rod 403 on its back, which cooperates with the casting clamp guide groove 404. The casting clamp guide groove 404 refers to a linear track structure extending longitudinally along the casting support frame 401, which can be formed by processing channel steel or U-shaped steel, and is used to constrain the movement trajectory of the locking clamp guide rod 403. The locking clamp guide rod 403 refers to a guide rod welded to the back of the locking semicircular clamp, and its diameter is clearance-fitted with the inner cavity of the guide groove 404. When the locking semicircular clamp is closed by driving it with bolts or locking cylinders, the guide rod 403 moves linearly along the guide groove 404, eliminating the radial offset of the clamp.

[0060] According to actual application needs, such as Figure 1 As shown, support screws 405 are installed at the four corners of the top of the casting support frame 401 to support the cap beam platform. The front and rear frames are connected by first connectors 406. The support screws 405 are column structures with threaded adjustment functions, specifically using double-ended studs with nuts for height adjustment. The first connectors 406 are rigid connection devices connecting the front and rear frames, specifically using channel steel or I-beams welded to form a box beam structure. The support screws 405 adjust the top elevation by rotating the nuts, keeping the cap beam platform level. The first connectors 405 rigidly connect the front and rear parts of the casting support frame, forming a closed force-bearing system.

[0061] In addition, such as Figures 1 to 6 As shown, this application further proposes a guardrail platform 500 arranged around the cylindrical pier. The guardrail platform 500 includes a platform step 501, a guardrail 502, and a second connector 503. The inner end of the platform step 501 is hinged to the top of the upper frame 101 of the upper clamping mechanism 100. The guardrail 502 is vertically installed on the top of the inner end and the outer end. The bottom of the outer end is inclined downward to the lower end of the upper frame 101 through the second connector 503.

[0062] The hinged connection at the inner end of the platform tread 501 refers to the use of a hinge structure between the platform and the top edge of the upper frame 201. The vertical installation of the guardrail 502 refers to the installation of an upright enclosure structure along the edge of the platform, forming a continuous protective interface to prevent personnel from falling. The downward-sloping connection of the second connector 503 refers to the use of a slanted support component, specifically a conventionally known adjustable-length steel connecting rod, which forms a stable triangular support system through hinges at both ends to distribute the platform load.

[0063] Combination Figures 1 to 8 As shown, the working principle of this automatic climbing concrete cylindrical pier climbing platform is as follows: An upper clamping mechanism 100 and a lower clamping mechanism 200 are configured vertically via a lifting cylinder 300. When the lower climbing clamp 202 inside the lower frame 201 is locked to the cylindrical pier by the lower locking cylinder 203, the lifting cylinder 300 is activated, causing the upper frame 101 to rise linearly. When the lifting cylinder 300 reaches the corresponding stroke, the upper climbing clamp 102 inside the upper frame 101 locks to the cylindrical pier. Then, the lower climbing clamp 202 inside the lower frame 201 is released, and the lifting cylinder 300 is activated, causing the lower frame 202 to rise. This process is repeated until the entire platform climbs to the corresponding height. When the platform reaches the corresponding height, the pouring clamping mechanism 400 is locked to the cylindrical pier by high-strength bolts, and then the cap beam pouring work begins. It should be noted that the specific control methods of the lifting cylinder and each locking cylinder in this climbing platform are existing known technologies and will not be elaborated here.

[0064] This application utilizes an upper clamping mechanism 100, a lower clamping mechanism 200, a lifting cylinder 300, a pouring clamping mechanism (400), a climbing platform, hydraulic cylinders, and a guardrail platform 500 to form a cylindrical pier climbing platform. By employing multiple sets of this cylindrical pier climbing platform, the cap beam support and formwork are assembled at a low position, lifted into place as a whole, and the pouring clamps are installed. During cap beam pouring, the climbing system is not subjected to stress. After cap beam construction is completed, the climbing system is used for overall dismantling, reducing high-altitude operations and ensuring safety. The prefabricated component design of this application's structure enables standardized factory assembly of the climbing mechanism and power structure.

[0065] The automatic climbing concrete cylindrical pier climbing platform of this application effectively solves the safety hazards for workers and transports the cap beam platform to the appropriate location more quickly and safely. Maintenance of each component is faster and simpler, greatly saving maintenance time and costs. It primarily addresses the safety hazards of placing formwork in the air, reduces the average cost of formwork manufacturing and the cost of using large formwork operating frames, improves the convenience and safety of on-site construction, enhances the image of civilized construction enterprises, and can be widely applied to construction operation platforms for concrete pouring in highways, high towers, bridge main towers, and observation towers.

[0066] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
