[0001] The invention relates to the technical field of building construction, and in particular to a self-climbing power system and method for an integrally hoisted steel platform. Background Art

It not only greatly improves the construction efficiency and shortens the construction period, but also is simple and convenient to operate, reducing the construction difficulty and labor costs. In addition, the overall climbing steel platform system is also highly safe and can effectively protect the personal safety of construction workers during the construction process and reduce the possibility of accidents.

[0003] The existing self-climbing power system for steel platforms is arranged with at least dozens of columns on each floor. The manual high-altitude switching of card blocks is labor-intensive, resulting in poor coordination between the various components of the system, causing frequent jams during the lifting process, further reducing construction efficiency. Summary of the invention

[0006] Preferably, the two top connection covers are fixedly connected to the climbing sleeves by bolts, and the left and right sides of the two bottom connection covers are fixedly connected with connection plates, and the two connection plates are slidably connected to the climbing sleeves.

[0007] Preferably, the top end of the rotating member at the top is fixedly connected to the bottom of the top locking mechanism, and the top end of the rotating member at the bottom is fixedly connected to the top of the bottom locking mechanism.

[0008] Preferably, protective fences are fixedly connected on both the front and rear sides between the two climbing sleeves, and the two hydraulic cylinders are located inside the two protective fences respectively.

[0009] Preferably, a fitting cavity is provided on the adjacent side of the two climbing sleeves, and two placement grooves are provided on the opposite sides of the inner walls of the two fitting cavities, and the two placement grooves are respectively located at the front and rear corners, and evenly distributed pulleys are rotatably connected in the four placement grooves.

[0010] Preferably, the front end of the locking pin is a wedge-shaped structure, and the inclination angle of the wedge-shaped structure is 30°-60°, so that it can better cooperate with the corresponding structure on the climbing column during the locking process.

[0011] Preferably, the pulley is made of polyketone and has anti-skid patterns on its surface to enhance the friction with the side of the climbing column and prevent the climbing sleeve from sliding and deviating during the climbing process.

[0012] A self-climbing power method for an integrally-lifted steel platform, the method comprising the following steps:

[0013] Step 1: Initial Lock

[0014] Start the system. Under the action of the spring damping rod, the locking pin in the bottom connecting cover uses the front wedge structure to slide in the slide groove and insert into the corresponding position of the rack on the climbing column to lock, thus realizing the initial locking of the climbing sleeve and the climbing column.

[0015] Step 2: Improve operation

[0016] The hydraulic cylinder starts to work, and the output end of the hydraulic cylinder extends to drive the rotating part to move. Since the rotating part is connected to the locking mechanism, it pushes the locking mechanism and the climbing sleeve to move upward along the climbing groove on the climbing column. During this process, the pulley rolls along the side of the climbing column to reduce the friction between the climbing sleeve and the climbing column. At the same time, the anti-skid pattern on the surface of the pulley ensures the stability of the climbing sleeve during movement without sliding and offset. As the hydraulic cylinder continues to extend, the climbing sleeve continues to rise. When the maximum stroke of the hydraulic cylinder is reached, the action of the hydraulic cylinder stops;

[0017] Step 3: Lock again

[0018] Under the action of the spring damping rod, the two locking pins at the top slide in the slide groove and insert into the corresponding position of the rack on the climbing column to lock the climbing sleeve firmly in the current position;

[0019] Step 4: Hydraulic cylinder reset

[0020] Subsequently, the hydraulic cylinder is controlled to retract, and the two locking pins are squeezed by the rack, causing the spring damping rod to contract under force, thereby lifting the two connecting covers at the bottom upwards, until the hydraulic cylinder contracts to the limit, and the spring damping rod releases its elastic force to push the locking pins back onto the rack for locking;

[0021] Step 5: Cycle Improvement

[0022] Repeat the above steps 2 to 4, through the continuous extension and retraction of the hydraulic cylinder and the alternating locking and unlocking of the locking mechanism, the overall lifting steel platform is gradually raised along the climbing column until it reaches the required height position;

[0023] Preferably, in step two, during the lifting operation, the contact portion between the locking pin and the rack is utilized to enhance the locking stability, and a groove matching the shape of the rack teeth is provided on the inner side of the wedge-shaped structure at the front end of the locking pin. When the locking pin is inserted into the rack, the groove and the teeth fit tightly together to increase the contact area and friction.

[0024] Preferably, in step 2, before the lifting operation, a micro pressure sensor is installed on the spring damping rod to monitor in real time the pressure applied by the spring damping rod to the locking pin.

[0025] The present invention provides a self-climbing power system and method for an integrally-lifted steel platform, which has the following beneficial effects:

[0026] 1. The present invention repeats initial locking and re-locking, and the process is automatically completed by driving the locking pin through the spring damping rod. There is no need to manually switch the card block position at high altitude. The locking process is coherent and efficient, which greatly shortens the time required for each locking, speeds up the overall operation rhythm of the steel platform self-climbing power system, improves construction efficiency, significantly reduces the workload of operators, and improves construction safety and convenience.

[0027] 2. During the lifting operation, the present invention not only uses the pulley to ensure stable movement, but also installs a micro pressure sensor on the spring damping rod to monitor the locking pin pressure in real time. The operator can make timely adjustments based on this to prevent unstable locking and re-lock to ensure that the climbing sleeve is stable at a new height. The hydraulic cylinder resetting process uses the elastic deformation of the spring damping rod to adapt to relative movement and maintain system stability, cyclic lifting, meet the requirements of different constructions for lifting height, and realize accurate and efficient steel platform lifting operations.

[0028] 3. The automatic locking mechanism of the system in the present invention operates based on physical principles and is less affected by the external environment. Regardless of the construction environment, it can complete initial locking and re-locking, ensuring the normal operation of the steel platform self-climbing power system in complex environments and improving the system's adaptability to different construction scenarios.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please see attached Figure 1 and attached Figure 4 -Attached Figure 6The embodiment of the present invention provides a self-climbing power system for an integrally lifted steel platform, comprising a climbing column 1, climbing sleeves 2 are provided on both sides of the climbing column 1, two connecting covers 8 are installed on both sides of the front and rear between the two climbing sleeves 2, climbing grooves 7 are provided at the central axis positions on both sides of the climbing column 1, racks 6 are fixedly connected to the sides of the inner walls of the two climbing grooves 7, and the notches of the two racks 6 are both facing upward, a hydraulic cylinder 4 is provided between two adjacent connecting covers 8, a rotating member 5 is fixedly connected to the top and output end of the two hydraulic cylinders 4, connecting members 9 are fixedly connected on both sides of the connecting cover 8, a spring damping rod 10 is rotatably connected between the two adjacent connecting members 9, a sliding groove 15 is provided at the center of the connecting cover 8, a locking pin 14 is slidably connected in the sliding groove 15, a rotating groove 16 is provided on the rear side of the locking pin 14, the bottom end of the spring damping rod 10 is located inside the rotating groove 16, and the spring damping rod 10 is rotatably connected to the locking pin 14.

[0038] The climbing column 1 serves as the supporting structure of the entire system and provides vertical guidance for the lifting of the steel platform. The climbing sleeves 2 arranged on both sides fit tightly against the climbing column 1, bear the weight of the steel platform, and move smoothly along the climbing column 1 during the lifting process. The symmetrical climbing sleeves 2 on both sides ensure the stability of the steel platform during lifting, prevent lateral deviation, and ensure the vertical rise of the steel platform.

[0039] The climbing groove 7 provides a track for the climbing sleeve 2 to rise, and the rack 6 is notched upward to cooperate with the locking pin 14 to realize the locking function. The teeth of the rack 6 and the structure of the locking pin 14 interact with each other to realize the positioning and fixation of the climbing sleeve 2 on the climbing column 1, prevent the climbing sleeve 2 from sliding down, ensure the safe and stable lifting of the steel platform, and roll along the side of the climbing column 1 when the climbing sleeve 2 rises.

[0040] When the system is locked, the spring damping rod 10 uses elastic potential energy to push the locking pin 14 to slide in the slide groove 15 and insert the rack 6 to achieve locking. Based on the elastic characteristics of the spring damping rod 10, it provides locking force and buffering at the same time, reduces the impact force at the moment of locking, protects the locking mechanism and the rack 6, and achieves the locking and unlocking of the climbing sleeve 2 and the climbing column 1, ensuring the safe and stable lifting of the steel platform.

[0041] Please see attached Figure 2 The two top connecting covers 8 are fixedly connected to the climbing sleeve 2 by bolts, and the left and right sides of the two bottom connecting covers 8 are fixedly connected with connecting plates 17, and the two connecting plates 17 are slidably connected to the climbing sleeve 2.

[0042] The top connecting cover 8 is fixed to the climbing sleeve 2 by bolts, which has high stability and reliability and can withstand the tension and pressure during the lifting process to ensure the stability of the top structure. The bottom connecting cover 8 is slidably connected to the climbing sleeve 2 through the connecting plate 17, which transmits the lifting power while ensuring the relative flexibility of the bottom structure to adapt to different lifting action requirements.

[0043] Please see attached Figure 1 The top of the top rotating member 5 is fixedly connected to the bottom of the top locking mechanism, and the top of the bottom rotating member 5 is fixedly connected to the top of the bottom locking mechanism.

[0044] Please see attached Figure 1 A protective fence 3 is fixedly connected between the two climbing sleeves 2 on both the front and rear sides, and two hydraulic cylinders 4 are located inside the two protective fences 3 respectively.

[0045] The protective fence 3 encloses the hydraulic cylinder 4 inside, providing safety protection for operators and equipment to prevent accidents causing injuries to personnel or damage to equipment. At the same time, it prevents dust and debris, ensures the normal operation of the components of the hydraulic cylinder 4, and extends the service life of the equipment.

[0046] Please see attached Figure 3 A fitting cavity 11 is provided on the adjacent side of the two climbing sleeves 2, and two placement grooves 13 are provided on the opposite side of the inner wall of the two fitting cavities 11, and the two placement grooves 13 are respectively located at the front and rear side corners, and the four placement grooves 13 are rotatably connected with evenly distributed pulleys 12.

[0047] Please see attached Figure 5 The front end of the locking pin 14 is a wedge-shaped structure, and the inclination angle of the wedge-shaped structure is 30°-60°, so that it can better cooperate with the corresponding structure on the climbing column 1 during the locking process.

[0048] When the locking pin 14 is inserted into the rack 6, this angle makes it easy to insert the locking pin 14, and a self-locking structure is formed after insertion. Based on the principle of mechanics, within this angle range, the locking pin 14 is subjected to a component force perpendicular to the tooth surface of the rack 6, which presses it onto the rack 6, thereby ensuring that the locking pin 14 is smoothly inserted and improving the locking stability, thereby preventing the locking pin 14 from loosening during lifting.

[0049] Please see attached Figure 3 The pulley 12 is made of polyketone and has anti-skid patterns on its surface to enhance the friction with the side of the climbing column 1 and prevent the climbing sleeve 2 from sliding and deviating during the climbing process.

[0050] The polyketone material has good wear resistance and excellent mechanical properties. It can withstand greater pressure and friction. The anti-slip texture increases the friction with the side of the climbing column 1 to prevent the climbing sleeve 2 from sliding and deviating. The pulley 12 reduces the friction between the climbing sleeve 2 and the climbing column 1, allowing the climbing sleeve 2 to rise smoothly, reduce energy consumption, and improve the safety and reliability of the lifting system.

[0051] Please see attached Figure 7 , a self-climbing power method for an integrally lifted steel platform, the method comprising the following steps:

[0052] Step 1: Initial Lock

[0053] After starting the system, the locking pin 14 in the bottom connection cover 8 moves under the action of the spring damping rod 10, and the elastic potential energy of the spring damping rod 10 is converted into the kinetic energy of the locking pin 14, so that it slides in the slide groove 15 using the front wedge structure and inserts into the corresponding position of the rack 6 on the climbing column 1. The initial locking provides a stable starting foundation for the lifting process, ensuring that the position of the steel platform is stable when it starts to lift, avoiding subsequent shaking or deviation, and using the elastic force of the spring damping rod 10 to push the locking pin 14 to cooperate closely with the rack 6, ensuring the safety and stability of the lifting system at the startup stage;

[0054] Step 2: Improve operation

[0055] When the hydraulic cylinder 4 works, the internal hydraulic oil pressure drives the piston to move, so that the output end extends and drives the rotating member 5 to move. The rotating member 5 is connected with the locking mechanism to convert the linear motion of the hydraulic cylinder 4 into the upward movement of the locking mechanism and the climbing sleeve 2. The pulley 12 rolls along the side of the climbing column 1. The wear resistance and anti-skid texture of the polyketone material ensure the stable movement of the climbing sleeve 2. Before the lifting operation, a micro pressure sensor is installed on the spring damping rod 10 to monitor the pressure applied by the spring damping rod 10 to the locking pin 14 in real time, so as to understand the contact state and locking force of the locking pin 14 and the rack 6. When the pressure is abnormal, the operator can adjust the lifting operation to avoid safety accidents caused by unstable locking. A groove matching the shape of the teeth of the rack 6 is arranged on the inner side of the wedge-shaped structure at the front end of the locking pin 14. When the rack 6 is inserted, the groove and the teeth are tightly fitted, increasing the contact area and friction, and enhancing the locking stability. By increasing the contact area and increasing the friction, the locking pin 14 is more firmly connected to the rack 6, ensuring that the climbing sleeve 2 and the climbing column 1 are reliably locked, and preventing the climbing sleeve 2 from sliding down or shaking when rising;

[0056] Step 3: Lock again

[0057] After the climbing sleeve 2 rises to the maximum stroke position of the hydraulic cylinder 4, the two locking pins 14 at the top slide in the slide groove 15 under the action of the spring damping rod 10 and insert into the corresponding position of the rack 6 on the climbing column 1 to lock. The purpose of re-locking is to establish a stable locking state after the climbing sleeve 2 reaches a new height. As the climbing sleeve 2 rises and changes its position, the top locking mechanism needs to be locked in time. The spring damping rod 10 releases elastic potential energy to push the locking pin 14 into the rack 6 to achieve re-locking, providing reliable positioning and fixation for the steel platform in the middle of the lifting position, and preventing the climbing sleeve 2 from sliding down after the hydraulic cylinder 4 stops working;

[0058] Step 4: Hydraulic cylinder reset

[0059] After the top locking pin 14 is locked again, the hydraulic cylinder 4 is controlled to retract. During the retraction, the two locking pins 14 are squeezed by the rack 6, causing the spring damping rod 10 to be forced to retract. The teeth of the rack 6 generate a reverse force on the locking pin 14, which is transmitted to the spring damping rod 10 through the locking pin 14 to compress it. The spring damping rod 10 contracts and lifts the two bottom connecting covers 8 upward until the hydraulic cylinder 4 contracts to the limit. At this time, the spring damping rod 10 releases the elastic force to push the locking pin 14 back onto the rack 6 and lock it. The elastic deformation characteristics of the spring damping rod 10 are used to adapt to the relative movement of the locking pin 14 and the rack 6 when the hydraulic cylinder 4 retracts, and it is re-locked after the hydraulic cylinder 4 retracts into place, preparing for the next lifting operation and ensuring the stability of the system during the resetting process of the hydraulic cylinder 4.

[0060] Step 5: Cycle Improvement

[0061] Repeat steps 2 to 4, and realize the overall lifting of the steel platform along the climbing column 1 to the required height through the continuous extension and retraction of the hydraulic cylinder 4 and alternating locking and unlocking. The cyclic lifting is based on the coordinated work of various components of the system. The hydraulic cylinder 4 provides power, and the locking mechanism ensures stable lifting positioning. Each cycle ensures that the extension and retraction of the hydraulic cylinder 4 and the locking mechanism are precisely coordinated to meet the requirements of different construction projects for the lifting height of the steel platform and realize the lifting operation of the steel platform.

[0062] Step two, during the lifting operation, the contact area between the locking pin 14 and the rack 6 is used to enhance the locking stability. The inner side of the wedge-shaped structure at the front end of the locking pin 14 is provided with a groove that matches the shape of the teeth of the rack 6. When the locking pin 14 is inserted into the rack 6, the groove and the teeth are tightly fitted to increase the contact area and friction.

[0063] In step 2, before the lifting operation, a micro pressure sensor is installed on the spring damping rod 10 to monitor the pressure applied by the spring damping rod 10 to the locking pin 14 in real time.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
