Description

Technical Field

[0001] The utility model relates to the field of hook reinforcement bending and welding construction, in particular to a hook reinforcement construction platform lifting platform. Background Art

[0002] Chinese patent CN116175171B provides a tower column hook reinforcement automatic installation robot system, including an inner cavity platform and an outer cavity platform, the inner cavity platform and the outer cavity platform are arranged on both sides of the steel bar component, the outer cavity platform is provided with an automatic feeding manipulator, one side of the automatic feeding manipulator is provided with a hook reinforcement material rack, the inner cavity platform is provided with a welding manipulator, the welding manipulator is provided with a bending and welding device, the automatic feeding manipulator passes the straight end of the hook reinforcement through the steel bar component, the welding manipulator bends the straight end of the hook reinforcement and welds it to the steel bar component through the welding device. On the outer cavity bracket of the component frame, an automatic hook reinforcement grabbing mechanism is provided at the bottom.

[0003] The equipment disclosed in this patent is the first generation of equipment. The lifting method adopted by the automatic feeding manipulator and the welding manipulator on the inner cavity platform and the outer cavity platform is that the motor drives the teeth to mesh with the gear rack to drive the manipulator to lift and lower on the platform. The lifting force method depends on the driving torque of the motor. In addition, the lifting platform is driven by a unilateral drive lifting method, and the other side uses rolling and sliding methods to move and lift. This unilateral drive lifting method has inherent limitations. Since the balance of the entire lifting system is completely dependent on the torque output of the unilateral motor, once there is an uneven load or the weight distribution of the manipulator itself changes during operation, it is easy to cause an imbalance in the lifting force, which in turn affects the normal output of the motor and may even cause a decrease in the driving force. In addition, when driven on one side, if one side bears too much weight, it will increase the wear of the rolling and sliding components, which may cause the instability of the lifting platform over time and increase the risk of equipment failure.

[0004] Although the single-sided drive lifting method has the characteristics of a relatively simple structure, in practical applications, especially in the automated production line environment that requires high quality and high stability, this design needs to be carefully considered, and it is necessary to explore more balanced and reliable double-sided drive or other multi-point drive lifting technology solutions to ensure the safety and stability of the automatic feeding and welding manipulator during the lifting process between the inner and outer cavity platforms. Utility Model Content

[0005] The main purpose of the utility model is to provide a lifting platform for a hook reinforcement construction platform, which solves the problem that the lifting platform is driven by a single-side driving lifting method and the other side is moved and lifted by rolling and sliding, and this single-side driving lifting method has inherent limitations.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lifting platform for hooking reinforcement construction, the reinforcement mesh preparation equipment includes a first working platform and a second working platform, a tire frame is arranged between the first working platform and the second working platform, and a lifting device is arranged on the first working platform and the second working platform, and the lifting device lifts the first lifting working unit on the first working platform;

[0007] The structure of the lifting device is as follows: the hook-rebar bending and welding equipment is arranged on the first lifting operation unit, lifting cylinders are symmetrically provided at both ends of one side of the first lifting operation unit, a lifting guide wheel is provided at the end of the telescopic rod of the lifting cylinder, one end of the lifting steel cable is connected to the first lifting operation unit, and the other end bypasses the lifting guide wheel and is connected to the working platform frame.

[0008] In the preferred embodiment, the first synchronous steel cable is provided at both ends of the other side of the first lifting operation unit, and the first lifting guide wheel and the second lifting guide wheel are provided on both ends of the side of the first lifting operation unit. One end of the first synchronous steel cable is connected to the top of the working platform frame, and the other end passes through the bottom of the first lifting guide wheel, and then passes through the top of the second lifting guide wheel to connect to the bottom of the working platform frame.

[0009] In the preferred embodiment, a wire pulling sensor is also provided on the first lifting operation unit, and the wire end of the wire pulling sensor is connected to the first lifting operation unit;

[0010] A small crane is also provided on the first lifting operation unit.

[0011] In the preferred embodiment, a second synchronous steel cable is provided between the lifting cylinder and the first lifting operation unit, a first double-guide groove guide wheel and a second double-guide groove guide wheel are provided at both ends of the side surface of the first lifting operation unit close to the lifting cylinder, and one end of the two second synchronous steel cables at both ends of the first lifting operation unit is connected to the top of the work platform frame;

[0012] The other end of one of the second synchronous steel cables passes under the first double guide groove guide wheel, and then passes over the second double guide groove guide wheel to connect with the bottom of the working platform frame. The other end of the second synchronous steel cable passes under the second double guide groove guide wheel, and then passes over the first double guide groove guide wheel to connect with the bottom of the working platform frame.

[0013] In the preferred embodiment, the first working platform and the second working platform have the same structure. The first working platform is provided with multiple flip working boards, one side of which is hinged to the working platform frame. The working platform frame is also provided with a flip cylinder, one end of which is hinged to the working platform frame, and the other end is hinged to the middle part of the working platform frame.

[0014] In the preferred embodiment, a plurality of positioning grooves are also provided on the tire frame, and the bottoms of the inner mesh, middle mesh and outer mesh are arranged inside the positioning grooves, and the inner mesh, middle mesh and outer mesh are connected to the first working platform and the second working platform on both sides by a plurality of basket bolts.

[0015] The utility model provides a lifting platform for a hook reinforcement construction platform. The design of a lifting cylinder, a steel cable and a guide wheel system is used to improve the original single-sided motor driven gear lifting method, and a double synchronous steel cable system "a first synchronous steel cable and a second synchronous steel cable" is used. Even when the lifting cylinder is driven on one side, the steel cable tensioning and the guide wheel guiding mechanism can ensure that the first lifting operation unit always maintains a horizontal state during the rising process, which significantly improves the stability of the lifting system and solves the problem of poor stability caused by the original single-sided motor drive.

[0016] Through the clever arrangement of steel cables and the use of double guide groove guide wheels, the forces on both sides can be evenly distributed, preventing the operating unit from tilting due to eccentric loading even when the load is uneven, reducing the risk of lifting failure due to insufficient driving force. Compared with solutions with multi-point drive or multiple cylinders working at the same time, this design solution only requires one side of the lifting cylinder to complete a stable lifting action, reducing equipment costs and improving energy efficiency.

[0017] By precisely controlling the telescopic stroke of the lifting cylinder and combining the synchronous tensioning and contraction of the steel cable, the lifting unit can be finely controlled, which enhances the operation accuracy. It reduces potential safety hazards caused by structural imbalance, helps improve the safety performance and service life of the overall equipment, and helps to ensure the continuity and reliability of the production process.

[0018] This improved design not only overcomes the shortcomings of the original single-sided motor driven lifting method, but also greatly improves the lifting efficiency and safety of the automatic feeding robot and welding robot on the inner and outer cavity platforms by making full use of mechanical mechanics principles and synchronous control technology, thereby achieving a more stable, precise and stable lifting function of the operating unit.

[0031] like Figures 1 to 9 As shown, a lifting platform for hooking reinforcement construction, the reinforcement mesh preparation equipment 4 includes a first working platform 402 and a second working platform 406, a tire frame 404 is arranged between the first working platform 402 and the second working platform 406, and a lifting device is arranged on the first working platform 402 and the second working platform 406, and the lifting device lifts the first lifting working unit 4024 on the first working platform 402;

[0032] The structure of the lifting device is as follows: the hook bar bending and welding equipment is arranged on the first lifting operation unit 4024, and lifting cylinders 4023 are symmetrically arranged at both ends of one side of the first lifting operation unit 4024, and a lifting guide wheel 11 is arranged at the end of the telescopic rod of the lifting cylinder 4023, and one end of the lifting steel cable 10 is connected to the first lifting operation unit 4024, and the other end bypasses the lifting guide wheel 11 and is connected to the work platform frame 4025. The end of the telescopic rod of the lifting cylinder 4023 lifts the lifting steel cable 10, and the lifting steel cable 10 drives the entire first lifting operation unit 4024 to start rising.

[0033] In the preferred embodiment, the first synchronous steel cable 12 is provided at both ends of the other side of the first lifting operation unit 4024, and the first lifting guide wheel 1201 and the second lifting guide wheel 1202 are provided on both ends of the side of the first lifting operation unit 4024. One end of the first synchronous steel cable 12 is connected to the top of the working platform frame 4025, and the other end passes through the bottom of the first lifting guide wheel 1201, and then passes through the top of the second lifting guide wheel 1202 to connect with the bottom of the working platform frame 4025.

[0034] Two lifting cylinders 4023 are arranged on one side of the first lifting work unit 4024, and a first synchronous steel cable 12 is arranged on the other side. The top of the first synchronous steel cable 12 is connected to the top of the working platform frame 4025, and the other end passes under the first lifting guide wheel 1201 in turn, and then passes over the second lifting guide wheel 1202 and is connected to the bottom of the working platform frame 4025. When the two lifting cylinders 4023 lift on one side, the first synchronous steel cable 12 on the other side will also realize the horizontal rise of the first lifting work unit 4024 under the action of the first lifting guide wheel 1201 and the second lifting guide wheel 1202. There is no need for multiple lifting cylinders 4023 to lift, and the first lifting work unit 4024 can be horizontally risen by using two first synchronous steel cables 12.

[0035] The first outer frame 4026 is arranged on the first lifting operation unit 4024, and both sides of the lifting operation unit have unique lifting drive and balancing mechanisms. The lifting cylinders 4023 are symmetrically mounted on both ends of one side, and the top of the telescopic rod of the lifting cylinder is equipped with a lifting guide wheel 11. One end of the lifting cable 10 is connected to the first lifting operation unit 4024, and the other end is wound around the work platform frame 4025 through the lifting guide wheel 11. When the telescopic rod of the lifting cylinder 4023 is extended, that is, the lifting cable 10 is lifted, the lifting cable pulls the entire first lifting operation unit 4024 up.

[0036] On the other side of the first lifting operation unit 4024, the first synchronous steel cable 12 is symmetrically arranged at both ends. Both sides of this side are equipped with a first lifting guide wheel 1201 and a second lifting guide wheel 1202. One end of the first synchronous steel cable 12 is fixed to the top of the work platform frame 4025, and the other end first passes under the first lifting guide wheel 1201, then passes over the second lifting guide wheel 1202, and finally connects to the bottom of the work platform frame 4025.

[0037] This design ensures that when only the two lifting cylinders 4023 on one side are working, through the tensioning of the first synchronous steel cable 12 and the guiding effect of the lifting guide wheel, the first lifting work unit 4024 can be kept horizontal during the ascent without the need for more lifting cylinders to work simultaneously, thus avoiding the problem of tilting and imbalance, thereby effectively utilizing the principles of mechanical mechanics and achieving a smooth ascent of the work unit.

[0038] In the preferred embodiment, a wire pulling sensor is further provided on the first lifting operation unit 4024 , and the wire end of the wire pulling sensor is connected to the first lifting operation unit 4024 ; the wire pulling sensor can sense the lifting position of the first lifting operation unit 4024 .

[0039] The first lifting operation unit 4024 is also provided with a small crane.

[0040] In the preferred embodiment, a second synchronous steel cable 13 is provided between the lifting cylinder 4023 and the first lifting operation unit 4024, and a first double-guide groove guide wheel 1301 and a second double-guide groove guide wheel 1302 are provided at both ends of the side of the first lifting operation unit 4024 near the lifting cylinder 4023, and one end of the two second synchronous steel cables 13 at both ends of the first lifting operation unit 4024 is connected to the top of the work platform frame 4025;

[0041] A second synchronous steel cable 13 is also provided on one side of the installation position of the lifting cylinder 4023 , and two second synchronous steel cables 13 are also symmetrically installed on one side of the first lifting operation unit 4024 .

[0042] The other end of one of the second synchronous steel cables 13 passes around the bottom of the first double guide groove guide wheel 1301, and then passes around from the top of the second double guide groove guide wheel 1302 to connect with the bottom of the working platform frame 4025. The other end of the second synchronous steel cable 13 passes around the bottom of the second double guide groove guide wheel 1302, and then passes around from the top of the first double guide groove guide wheel 1301 to connect with the bottom of the working platform frame 4025.

[0043] The other end of the second synchronous steel cable 13 passes under the first double-guide groove guide wheel 1301, and then passes over the second double-guide groove guide wheel 1302 to connect with the bottom of the working platform frame 4025. During the lifting process of the lifting cylinder 4023, the second synchronous steel cable 13 cooperates with the first synchronous steel cable 12, and the first lifting operation unit 4024 can rise more smoothly.

[0044] A second synchronous steel cable 13 system is also added between the lifting cylinder 4023 and the first lifting operation unit 4024 to further enhance the balance and stability of the operation unit during lifting. A first double-guide groove guide wheel 1301 and a second double-guide groove guide wheel 1302 are provided at both ends of the side of the first lifting operation unit 4024 near the installation position of the lifting cylinder.

[0045] One end of the two second synchronous steel cables 13 is connected to the top of the work platform frame 4025. The other end of one of the second synchronous steel cables 13 first passes under the first double-groove guide wheel 1301, then bypasses over the second double-groove guide wheel 1302, and finally connects to the bottom of the work platform frame 4025; while the other second synchronous steel cable 13 passes under the second double-groove guide wheel 1302, then bypasses over the first double-groove guide wheel 1301, and connects to the bottom of the work platform frame 4025.

[0046] When the lifting cylinder 4023 performs the lifting operation, the second synchronous steel cable 13 and the first synchronous steel cable 12 mentioned above work together to ensure that the first lifting operation unit 4024 always maintains a horizontal position during the lifting process through the alternating traction of the double guide groove guide wheel, and is not tilted by the unilateral force, thereby achieving a more stable and precise lifting action. Through this sophisticated synchronous control system, the imbalance phenomenon during the lifting operation is effectively avoided, ensuring the efficient and stable operation of the entire lifting operation unit.

[0047] The first working platform 402 and the second working platform 406 have the same structure. The first working platform 402 is provided with a plurality of flip working panels 4022. One side of the flip working panel 4022 is hinged to the working platform frame 4025. The working platform frame 4025 is also provided with a flip cylinder 4021. One end of the flip cylinder 4021 is hinged to the working platform frame 4025, and the other end is hinged to the middle part of the working platform frame 4025.

[0048] When the steel bar preparation device for the steel mesh of the tower steel bar parts is in operation, the flipping oil cylinder 4021 drives the flipping work plate 4022 to fold, which is convenient for the automatic bending and welding unit 405 and the automatic feeding and welding unit 403 to move up and down for construction. When the automatic bending and welding unit 405 and the automatic feeding and welding unit 403 are not in operation, the flipping oil cylinder 4021 drives the flipping work plate 4022 to unfold and flatten, which is convenient for construction personnel to perform manual inspection and manual leak repair on the flipping work plate 4022. In order to adjust the position of the working surface according to actual needs, it greatly improves the adaptability and flexibility of the hook bar installation operation, thereby improving the overall construction efficiency and installation accuracy.

[0049] In the preferred embodiment, a plurality of positioning grooves are also provided on the tire frame 404, and the bottoms of the inner mesh, the middle mesh and the outer mesh 7 are arranged inside the positioning grooves, and the inner mesh, the middle mesh and the outer mesh are connected to the first working platform 402 and the second working platform 406 on both sides by a plurality of basket bolts.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
