Description

Technical Field

[0001] This invention belongs to the field of high-altitude operation safety protection technology, specifically a modular safety operation platform. Background Technology

[0002] In industrial sectors such as construction, bridge building, shipbuilding, and large equipment installation, safe operating platforms are of great significance. At heights in construction, they assist workers in precise construction; on bridges, they ensure safety during complex operations; in shipbuilding, they provide a stable operating space; and during large equipment installation, they allow technicians to work with peace of mind, making them crucial for ensuring both construction safety and efficiency. According to publication number CN208918231U, entitled "A Safe and Stable Welding Operation Platform for the Upper Part of a Steel Column," the platform includes a steel column and an operation platform. A support frame is provided on the outer side of the steel column. The operation platform is located on the outer side of the steel column and installed on the upper part of the support frame. Platform tie rods are provided on the outer side of the operation platform. An openable platform plate is provided on the operation platform. Connecting stiffeners are provided on the outer side of the steel column above the operation platform, with the lower part of the connecting stiffeners connected to the operation platform. A safety ladder is provided on the side of the steel column below the operation platform. This utility model increases the stability and safety of the entire platform structure by setting up an operation platform around the steel column and providing support frames and platform tie rods on the operation platform. The connecting stiffeners on the outer side of the steel column further improve the stability of the connection between the steel column and the operation platform. The safety ladder facilitates quick access for construction personnel to the operation platform, thereby improving construction safety. However, in actual use, the platform has revealed some problems that cannot be ignored. The operating platform is typically fixed to the steel column surface using bolts, a method that has significant drawbacks in complex construction environments. When operators stand on the platform to perform welding work, vibrations generated during welding and dynamic loads from the operators' movements contribute to the problem. Under the combined effect of these factors, the bolted connections are prone to loosening. Once the bolts loosen, the operating platform may descend, disrupting the normal construction schedule and, more seriously, significantly reducing the overall fixation effectiveness and compromising the stability of installation and welding work. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a modular safe operating platform.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a modular safety operating platform, comprising a base, a guardrail, and a bolt mounting plate, and further comprising: A locking mechanism is located at the bottom end of the base; The locking mechanism includes a pressing block fixedly connected to the bottom of the base, a moving block is provided on one side of the pressing block, an elastic element is fixedly installed on one side of the moving block, and an installation plate is fixedly installed on one end of the elastic element. The drive component is located at the bottom of the base.

[0005] Preferably, the drive assembly includes a square plate fixedly connected to the bottom of the base, a motor is fixedly installed at the bottom of the square plate, a lead screw located inside the mounting plate is fixedly installed at the output end of the motor, and the mounting plate and the lead screw are threadedly connected.

[0006] Preferably, it further includes: A blocking mechanism is provided at the bottom end of a square plate. The blocking mechanism includes a connecting plate fixedly connected to the bottom end of the square plate. A pneumatic telescopic rod is fixedly installed on the side of the connecting plate near the surface of the moving block. A mounting shell is fixedly installed on the output shaft of the pneumatic telescopic rod. A neodymium magnet is fixedly installed inside the mounting shell near the surface of the moving block. A circular cylinder is fixedly installed at the bottom end of the square plate. A piston rod is slidably connected inside the circular cylinder and fixedly connected to the top end of the mounting plate. The circular cylinder and the pneumatic telescopic rod are connected through an air injection pipe. A metal plate is provided on one side of the neodymium magnet and fixedly connected to the moving block.

[0007] Preferably, a limiting rod located inside the mounting plate is fixedly installed at the bottom end of the square plate, and the mounting plate can slide on the surface of the limiting rod. The limiting rod is square in design, and the surface of the limiting rod is in contact with the inner wall of the mounting plate. The limiting rod is mirror-shaped.

[0008] Preferably, the pressing block and the moving block are both designed with inclined surfaces on opposite sides, and the two inclined surfaces are designed to be parallel.

[0009] Preferably, the elastic element has a telescopic rod inside, and both ends of the telescopic rod are fixedly connected to one side of the mounting plate by the movable block. The elastic element is designed longitudinally about the center of the movable block.

[0010] Preferably, the other side of the moving block has an arc-shaped design, and a friction block is provided on the other side of the moving block, and the number of friction blocks is multiple.

[0011] Preferably, the surface of the connecting plate has a square hole, and the piston rod can slide inside the square hole, with the surface of the piston rod fully fitting the inner wall of the square hole.

[0012] Preferably, the surface of the piston rod is in contact with the inner wall of the cylindrical cylinder, and the piston rod located inside the cylindrical cylinder is circular in design.

[0013] Preferably, a gap is designed between the connecting plate and the mounting plate, and the air injection pipe is made of rigid PVC material.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention drives the motor to rotate the lead screw, and the mounting plate slides on the surface of the lead screw. The mounting plate drives the elastic element and the moving block to move. When the moving block moves, the pressing block presses and pushes the moving block to move towards the surface of the rod. When the moving block moves, the elastic element is stretched. Then the moving block will abut against the surface of the rod. Finally, the drive motor makes the moving block abut against the surface of the rod, which greatly improves the overall fixing effect and ensures the stability of installation and welding work. This invention utilizes a piston rod that slides inside a cylindrical tube as the mounting plate moves upward. The moving piston rod pushes air from inside the cylinder into a pneumatic telescopic rod. With continuous gas injection, the output shaft of the pneumatic telescopic rod activates, pushing the mounting shell and neodymium magnets to move. The surfaces of the mounting shell and neodymium magnets then come into contact with the surface of the metal plate. The thrust of the output shaft causes the neodymium magnets to abut against the surface of the metal plate, attracting them. Ultimately, the mounting plate, in conjunction with the piston rod, ensures the neodymium magnets abut against and adhere to the surface of the metal plate, thereby improving the contact effect of the moving block and ensuring the stability of the entire device.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 6 As shown, the present invention provides a modular safety operating platform, including a base 1, a guardrail 2, and a bolt mounting plate 3, and further comprising: Locking mechanism 4 is located at the bottom end of base 1; The locking mechanism 4 includes a pressing block 401 fixedly connected to the bottom of the base 1, a moving block 402 is provided on one side of the pressing block 401, an elastic element 403 is fixedly installed on one side of the moving block 402, and an installation plate 404 is fixedly installed on one end of the elastic element 403. The drive component 5 is located at the bottom of the base 1.

[0019] The drive assembly 5 includes a square plate 501 fixedly connected to the bottom of the base 1. A motor 502 is fixedly installed at the bottom of the square plate 501. A lead screw 503 located inside the mounting plate 404 is fixedly installed at the output end of the motor 502. The mounting plate 404 is threadedly connected to the lead screw 503.

[0020] Using the above method: the operator uses hoisting equipment to precisely lift the base 1 and guardrail 2 between the gate rods. With precise positioning, the two bases 1 and guardrail 2 are stably fitted onto the surface of the rods, preparing for subsequent fixing operations. Then, the operator carefully inserts the bolts into the bolt mounting plate 3. Through the tightening action of the bolts, the base 1 and guardrail 2 are initially fixed to the surface of the rods, initially building a relatively stable operating space. When a more secure fixation is required, the operator starts motor 502. Motor 502 begins to run and drives lead screw 503 to rotate. Since lead screw 503 and mounting plate 404 are connected by a thread, under the rotation of lead screw 503, mounting plate 404 will slide smoothly along the surface of lead screw 503. During the movement of mounting plate 404, it will drive the connected elastic element 403 and moving block 402 to move together. As moving block 402 continues to move, it will gradually come into contact with pressing block 401. At this time, pressing block 401 will... A compressive force is applied to the movable block 402, pushing it closer to the surface of the rod. During this process, the elastic element 403 is gradually stretched, generating a reverse elastic force. Ultimately, under the combined action of the compressive block 401 and the elastic element 403, the movable block 402 is tightly pressed against the surface of the rod, greatly enhancing the fixing effect between the entire device and the rod. This provides a solid and reliable guarantee for workers to stand inside the base 1 to install and weld the triangular arc gate space rod, ensuring the stability and safety of the construction process.

[0021] like Figure 5 and Figure 6 As shown, it also includes: The contact mechanism 6 is located at the bottom of the square plate 501. The contact mechanism 6 includes a connecting plate 601 fixedly connected to the bottom of the square plate 501. A pneumatic telescopic rod 602 is fixedly installed on the side of the connecting plate 601 near the surface of the moving block 402. A mounting shell 603 is fixedly installed on the output shaft of the pneumatic telescopic rod 602. A neodymium magnet 604 is fixedly installed inside the mounting shell 603 near the surface of the moving block 402. A cylindrical cylinder 605 is fixedly installed at the bottom of the square plate 501. A piston rod 606 is slidably connected inside the cylindrical cylinder 605. The piston rod 606 is fixedly connected to the top of the mounting plate 404. The cylindrical cylinder 605 and the pneumatic telescopic rod 602 are connected through an air injection pipe 607. A metal plate 608 is provided on one side of the neodymium magnet 604. The metal plate 608 is fixedly connected to the moving block 402.

[0022] Using the above scheme: When the mounting plate 404 moves upward under the action of driving force, the mounting plate 404 is tightly connected to the piston rod 606. As the mounting plate 404 moves upward, the piston rod 606 simultaneously begins to slide inside the cylindrical cylinder 605. When the piston rod 606 slides inside the cylindrical cylinder 605, it gradually compresses the air inside the cylindrical cylinder 605, forcing the air to flow through the air injection pipe 607. Since the cylindrical cylinder 605 and the pneumatic telescopic rod 602 are connected through the air injection pipe 607, the compressed air smoothly enters the pneumatic telescopic rod 602 through the air injection pipe 607. With the continuous injection of air, the air pressure inside the pneumatic telescopic rod 602 gradually increases, and its output shaft begins to exert force under the action of air pressure, generating a strong driving force. This driving force acts on the mounting shell 603, making... The mounting housing 603 moves the neodymium magnet 604 together. During the movement, the surfaces of the mounting housing 603 and the neodymium magnet 604 gradually approach the metal plate 608 and eventually come into close contact with the surface of the metal plate 608. At this time, the thrust of the output shaft plays a key role, causing the neodymium magnet 604 to press tightly against the surface of the metal plate 608. Due to its strong magnetism, the neodymium magnet 604 quickly adheres to the metal plate 608, forming a stable connection. Through the linkage process, the movement of the mounting plate 404 successfully links the piston rod 606, thereby causing the neodymium magnet 604 to press against and adhere to the surface of the metal plate 608. This design greatly improves the contact effect of the moving block 402, providing a more reliable stability guarantee for the entire device and ensuring that the device can always remain stable in complex working environments.

[0023] like Figure 3 and Figure 4 As shown, a limiting rod 7 located inside the mounting plate 404 is fixedly installed at the bottom end of the square plate 501, and the mounting plate 404 can slide on the surface of the limiting rod 7. The limiting rod 7 is square in design, and the surface of the limiting rod 7 is in contact with the inner wall of the mounting plate 404. The limiting rod 7 is mirrored.

[0024] The above solution is adopted so that when the mounting plate 404 moves under the action of driving force, it will slide smoothly along the surface of the limiting rod 7. The limiting rod 7 has a square design, and its square surface is in close contact with the inner wall of the mounting plate 404. This close contact effectively limits the direction of movement of the mounting plate 404, so that it can only move stably along the predetermined path on the surface of the lead screw 503, avoiding instability such as deviation and shaking. Moreover, the limiting rod 7 adopts a mirror design. This symmetrical structure further enhances its limiting effect. No matter which direction the mounting plate 404 moves, the limiting rod 7 can provide a balanced and stable constraint force from both sides, ensuring that the mounting plate 404 remains stable and accurate throughout the entire movement process, providing a solid and reliable guarantee for the stable operation of the entire device.

[0025] like Figure 4and Figure 5 As shown, the pressing block 401 and the moving block 402 are both designed with inclined surfaces on opposite sides, and the two inclined surfaces are designed to be parallel. The elastic element 403 is provided with a telescopic rod inside, and both ends of the telescopic rod are fixedly connected to one side of the moving block 402 and the mounting plate 404. The elastic element 403 is designed longitudinally about the center of the moving block 402.

[0026] The above solution employs a design where the extrusion block 401 and the moving block 402 are both designed with inclined surfaces on opposite sides, and these two inclined surfaces are parallel. When the extrusion block 401 applies force to the moving block 402, the parallel inclined surface structure effectively reduces the friction between the extrusion block 401 and the moving block 402. This friction reduction effect is significant, ensuring that the extrusion block 401 can smoothly and easily extrude and push the moving block 402, making the entire power transmission process more efficient and precise. The design of the moving block 402 also enhances elasticity. The elastic element 403 is equipped with a telescopic rod inside. When the elastic element 403 is stretched during the movement of the moving block 402, the telescopic rod will extend accordingly. The extension of the telescopic rod can not only limit the elastic element 403 and prevent it from being damaged due to excessive stretching, but also provide solid support for the moving block 402 and the mounting plate 404. During the operation of the device, no matter what kind of external interference or complex working conditions it faces, the telescopic rod can ensure the stability of the movement of the moving block 402 and the mounting plate 404, so that the entire device can always maintain a good working condition and lay a solid foundation for the smooth operation of various tasks.

[0027] like Figure 5 and Figure 6 As shown, the other side of the moving block 402 is arc-shaped, and a friction block is provided on the other side of the moving block 402. There are multiple friction blocks. The surface of the connecting plate 601 is provided with a square hole, and the piston rod 606 can slide inside the square hole. The surface of the piston rod 606 is fully in contact with the inner wall of the square hole.

[0028] The above solution employs the following design: The movable block 402 is designed with an arc shape on one side. In actual operation, the connecting rod and movable block 402 need to fit tightly together. The arc shape allows the connecting rod and movable block 402 to fully conform, greatly increasing the contact area and fit between them. Furthermore, a friction block is specifically provided on the other side of the movable block 402. When the connecting rod contacts the movable block 402, the friction block significantly increases the friction between them, ensuring that the connecting rod and movable block 402 will not loosen or slip during device operation, thus guaranteeing the fixing effect. The stability of the entire device is greatly improved. Through the design of the connecting plate 601 and the piston rod 606, since the surface of the connecting plate 601 has a square hole, when the piston rod 606 moves under power, it will slide smoothly inside the square hole, and the connecting plate 601 will not interfere with its movement. This ensures that the piston rod 606 can run according to the predetermined trajectory and speed. At the same time, the surface of the piston rod 606 is in close contact with the inner wall of the square hole. This contact design also plays a limiting role for the piston rod 606, preventing it from deviating or shaking during movement, thus ensuring the accuracy and stability of the entire device.

[0029] like Figure 5 and Figure 6 As shown, the surface of the piston rod 606 is in contact with the inner wall of the cylindrical cylinder 605, and the piston rod 606 located inside the cylindrical cylinder 605 is circular. There is a gap between the connecting plate 601 and the mounting plate 404, and the air injection pipe 607 is made of rigid PVC material.

[0030] The above-mentioned design, involving the cylindrical cylinder 605 and the piston rod 606, achieves a tight fit between the piston rod 606 and the inner wall of the cylindrical cylinder 605. This fit is not a simple contact but rather a near-seamless state. During actual operation, when the piston rod 606 reciprocates within the cylindrical cylinder 605, this tight fit effectively prevents air from leaking out through the gap between the cylindrical cylinder 605 and the piston rod 606. Air leakage would severely affect the pressure stability inside the cylindrical cylinder 605, thus impacting the overall operation of the device. This design ensures excellent sealing of the cylindrical cylinder 605, allowing the internal air to flow according to a predetermined path and pressure, thus facilitating subsequent airflow. The dynamic operation provides reliable protection. Through the design of the connecting plate 601 and the mounting plate 404, a certain gap is specially designed between the connecting plate 601 and the mounting plate 404 to ensure that the connecting plate 601 will not interfere with the movement of the mounting plate 404. This allows the mounting plate 404 to move freely and smoothly under the action of driving force. In addition, the air injection pipe 607 is made of rigid PVC material, which has sufficient strength and rigidity. When the pneumatic telescopic rod 602 pushes the mounting shell 603 and the neodymium magnet 604 to move, the air injection pipe 607 will not bend or deform due to force, thereby avoiding the air injection pipe 607 interfering with this critical movement process and ensuring the smoothness and stability of the entire device operation.

[0031] Working principle and usage process of this invention: Operators need to use professional hoisting equipment to precisely hoist the two bases 1 and guardrails 2 between the gate rods. During the hoisting process, the operating speed and direction of the equipment must be strictly controlled to ensure that the bases 1 and guardrails 2 can be stably and accurately fitted onto the surface of the rods, laying a good foundation for subsequent fixing work. After the bases 1 and guardrails 2 are in place, the operators insert bolts into the bolt mounting plate 3 and tighten the bolts to firmly fix the bases 1 and guardrails 2 to the surface of the rods, preventing them from shifting or shaking during operation. After fixing is completed, the workers can stand inside the bases 1 to carry out the installation and welding work of the triangular arc gate space rods. During installation, to further improve the stability of the fixation, a motor 502 can be used to drive the lead screw 503 to rotate. When the lead screw 503 rotates, the mounting plate 404 will slide smoothly along the surface of the lead screw 503. The movement of the mounting plate 404 will drive the elastic element 403 and the moving block 402 connected to it to move synchronously. During the movement of the moving block 402, the pressing block 401 will apply a pressing force to it, causing the moving block 402 to move closer to the surface of the rod. As the moving block 402 moves, the elastic element 403 will be gradually stretched, generating a certain elastic potential energy. When the moving block 402 touches the surface of the rod, the elastic potential energy of the elastic element 403 will be converted into pressure on the moving block 402, further enhancing the friction between the moving block 402 and the rod, thereby improving the fixing effect and ensuring the stability of the installation work. As the mounting plate 404 moves upward, the piston rod 606 slides inside the cylindrical cylinder 605. The movement of the piston rod 606 pushes the air inside the cylindrical cylinder 605 into the air injection pipe 607, and finally into the pneumatic telescopic rod 602. As the gas is continuously injected, the air pressure inside the pneumatic telescopic rod 602 gradually increases, and its output shaft begins to extend outward, pushing the mounting shell 603 and the neodymium magnet 604 toward the surface of the metal plate 608. When the surfaces of the mounting shell 603 and the neodymium magnet 604 come into contact with the surface of the metal plate 608, the thrust of the output shaft will cause the neodymium magnet 604 to press tightly against the surface of the metal plate 608. Due to the strong magnetism of the neodymium magnet 604, it will quickly adhere to the metal plate 608, forming a stable connection. This design further ensures the fixing effect of the moving block 402, providing a reliable guarantee for the entire installation and welding operation process.
