Description

Technical Field

[0001] This invention relates to the field of construction operation platform technology, specifically a mobile and safe operation platform suitable for tall retaining walls. Background Technology

[0002] Mobile construction operation platforms are temporary structures used for high-altitude operations on construction sites. They are mobile and commonly used in scenarios such as decoration, equipment installation, and water and electricity pipeline laying, and can flexibly adapt to the needs of different work sites.

[0003] However, the following drawbacks exist in practical use: 1. High safety risks: The original scaffolding platform and aerial work platform were used for the operation. The scaffolding erection and dismantling process, as well as the operation of the aerial work platform and the transfer of vehicles between sites, all had high safety risks. In addition, the construction of the retaining wall required frequent transfers to carry out settlement joint work and drainage hole repair, which further increased the safety hazards of working at height. 2. Low efficiency and long time consumption: The erection and dismantling of scaffolding platforms takes a long time and has low efficiency per use, making them unsuitable for construction needs with long routes and frequent site changes; the aerial work platform is frequently moved and has insufficient adaptability. 3. High construction costs: The investment in aerial work platform equipment is large, and the erection and dismantling of scaffolding requires a lot of manpower, resulting in high overall construction costs; 4. Poor adaptability: Construction sites are narrow, making it difficult for aerial work platforms to operate and pass each other in confined areas. Scaffolding platforms cannot flexibly adapt to the needs of high-frequency relocation and long-line retaining wall construction. Summary of the Invention

These units are used to install and fix the hoisting ropes that are wound inside the platform, and the hoisting ropes are automatically wound and unwound by an internal automatic winding and unwinding system.

[0022] As a preferred embodiment of the present invention, the safety protection structure includes:

[0023] A locking buckle is installed and wrapped around the outside of the lifting rope, and a safety steel rope is connected to the base of the locking buckle, the safety steel rope passing through the collar.

[0025] The steel rope winding and unwinding device is installed on the front of the horizontal beam plate by screws. The steel rope winding and unwinding device uses an internal self-locking system to install and position the safety steel rope in the winding and unwinding state.

[0026] As a preferred embodiment of the present invention, the horizontal moving structure includes:

[0027] A linear motor is mounted on one side of the top of the horizontal operating platform. The output end of the linear motor is connected to a first gear, and the bottom of the first gear is meshed with a second gear.

[0028] The first gear and the second gear are both rotatably connected to the inner wall of the horizontal operating platform.

[0029] A central reciprocating lead screw is connected to the second gear and rotatably connected at the center inside the horizontal operating platform. A horizontal slider is connected to the outer side of the central reciprocating lead screw via ball bearings. A lower base plate is fixed to the top of the horizontal slider by screws.

[0030] The lower base plate has a work protection structure fixed to its top by screws, and a tooth limiting structure located on the side of the middle reciprocating lead screw is installed on the side of the lower base plate.

[0031] The guide seat is fixed to the left and right sides of the bottom of the lower base plate by screws. The guide seat is slidably connected to the outside of the horizontal guide rail. The horizontal guide rail is installed inside the horizontal operating platform and is located on the left and right sides of the middle reciprocating lead screw.

[0032] As a preferred embodiment of the present invention, the tooth limiting structure includes:

[0033] A transmission gear is rotatably connected to one side of the bottom of the lower base plate. A horizontal toothed rod is meshed with the side of the transmission gear. The horizontal toothed rod is installed inside the horizontal operating platform and is located between the intermediate reciprocating lead screw and the horizontal guide rail.

[0034] A one-way groove is formed inside the end of the transmission gear shaft. A limiting block extending outward is provided inside the one-way groove. The limiting block is connected to the output end of the vertical electric cylinder.

[0035] The vertical electric cylinder is installed and fixed on the side of the work protection structure.

[0036] As a preferred embodiment of the present invention, the outer side of the limiting block is provided with a plurality of protrusions protruding outward, and the limiting block matches the one-way groove through the protrusions, and limits and fixes the position of the transmission gear.

[0037] As a preferred embodiment of the present invention, the work protection structure includes:

[0038] The Z-shaped work platform is fixed to the top of the lower base plate by screws. The Z-shaped work platform has a storage cavity inside, and the sides of the storage cavity are provided with ramps.

[0039] The vertical electric cylinder is installed and fixed on one side of the Z-shaped work platform;

[0040] A protective net is installed at the top edge of the Z-shaped work platform.

[0041] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In mobile safety operating platforms suitable for high retaining walls, during the lifting and support of the horizontal operating platform using hoisting ropes, the diagonally positioned hoisting ropes, together with the steel structure and the horizontal operating platform, form a triangular structure. This ensures that the horizontal operating platform maintains its shape stability under dynamic loads (such as wind force and load swaying), preventing twisting or overturning. Simultaneously, the stress on the horizontal operating platform is clearly defined, and compared to rectangular or pure beam structures, it can achieve significantly higher bending stiffness with a smaller material cross-section, reducing the probability of deformation. The hoisting ropes, through the safety steel rope structure on their outer side, provide lateral tension support and form a stable triangular structure with the steel structure and hoisting ropes. This restricts the horizontal displacement of the operating platform in both forward-backward and left-right horizontal directions, significantly reducing the impact tension on the hoisting ropes during platform startup, braking, or wind vibration, improving the fatigue life of the hoisting ropes and connectors, reducing the dynamic load on the hoisting ropes, and resulting in greater stability. 2. In the context of mobile safety operation platforms suitable for high retaining walls, the safety risks of working at heights can be reduced. The "riding-on" mobile operation platform design avoids the safety hazards associated with scaffolding erection and dismantling, as well as the relocation and maneuvering of aerial work platforms, ensuring the safety of construction workers. Simultaneously, it improves work efficiency, making the operation platform easy to move and use, adapting to the construction needs of long retaining wall routes and frequent relocations, reducing the time spent on erection and dismantling, and increasing the efficiency of each use. Furthermore, it can reduce construction costs by minimizing the investment in scaffolding manpower and aerial work platform equipment, thus optimizing construction costs. It should be noted that this can improve site adaptability, adapt to narrow construction sites, and enable the platform to move flexibly and park conveniently, meeting the construction needs of settlement joint operations and drainage hole repair. 3. In the mobile safety operation platform suitable for high retaining walls, when the Z-shaped work platform is moved horizontally to realize the relocation operation of the construction position, the Z-shaped work platform after the relocation can be fixed by the gear and toothed rod, and the one-way ratchet for secondary positioning. This ensures that the Z-shaped work platform after the relocation will not be displaced due to the shift of the center of gravity caused by the increase or decrease of the internal building materials, thus ensuring the safety of construction personnel during construction.

[0070] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example 1

[0071] Please see Figures 1-15 A movable safety operating platform suitable for high retaining walls includes a steel structure 10, which is bolted to the side of the retaining wall. A riding-mounted operating platform device 20 is mounted on the side of the steel structure 10. A triangular support frame 30 is screwed to the bottom of the riding-mounted operating platform device 20 and screwed to the side of the steel structure 10. The riding-mounted operating platform device 20 includes: a rigid locking structure 201 installed inside the steel structure 10 and extending outwards; a lifting rope 202 wound and fixed to the root of the rigid locking structure 201; and a support installed on the lifting rope 202. 02 A horizontal support and fixing structure 203 is connected to the side of the rigid locking structure 201 at the bottom; a safety protection structure 204 is wrapped and fixed to the outside of the hoisting rope 202 and installed and fixed to the side of the steel structure 10; a horizontal moving structure 205 is installed on the top of the horizontal support and fixing structure 203; a tooth limit structure 206 is installed on the side of the horizontal moving structure 205; and a work protection structure 207 is installed on the top of the horizontal moving structure 205 by screws. The hoisting rope 202 is stretched and positioned by the safety protection structure 204 and forms a triangular support and protection structure with the steel structure 10.

[0072] It should be noted that the steel structure 10 is composed of multiple vertical beams 101 and multiple horizontal beams 102. Multiple horizontal beams 102 are welded and fixed to the inner side of two vertical beams 101. Rigid locking structures 201 extending to the outside are installed inside the vertical beams 101 and the horizontal beams 102. A safety protection structure 204 is installed and fixed to the front of the horizontal beams 102 by screws, and a triangular support frame 30 is installed and fixed to the side of the vertical beams 101 by screws.

[0073] The working principle described above is as follows: When constructing a tall retaining wall (building), the steel structure 10 is first installed on the side of the retaining wall (building) using screws, serving as a load-bearing and supporting structure. Then, multiple rigid locking structures 201 are installed and fixed inside the steel structure 10 through drilling. The horizontal support fixing structure 203 is then installed and positioned on the side of the steel structure 10 using hoisting ropes 202 and side support positioning. The triangular support structure formed by the steel structure 10, the horizontal support fixing structure 203, and the hoisting ropes 202 supports and positions the horizontal support fixing structure 203, ensuring stability and safety during subsequent construction. During construction, the horizontal moving structure 205 can be activated from the control console inside the work protection structure 207, causing the work protection structure 207 to move horizontally, meeting the needs of high-frequency site transfers and improving construction efficiency. Meanwhile, during each high-frequency site transfer for construction, the tooth-limiting structure 206 can limit, fix, and lock the position after the transfer, ensuring that the position of the work protection structure 207 will not move when the workers are secured with safety ropes and carry out settlement joint work and drainage hole repair through the work passage and work window, thus enhancing safety.

[0074] It should be noted that the 207 work protection structure completely avoids the safety risks of working at heights and relocation through an integrated safety protection design; the coordinated design of the four major modules of support, movement, protection and operation realizes that the platform is "no need to be erected, flexible to move, safe and efficient", which can meet the pain points of retaining wall construction, reduce costs and improve efficiency.

[0075] For details, please refer to the following: Figure 8 and Figure 9 The rigid locking structure 201 includes a first drilled hole 2011, which is formed inside the vertical beam plate 101 and the horizontal beam plate 102. A rigid sleeve 2012 is provided inside the first drilled hole 2011. The head of the rigid sleeve 2012 is provided with multiple expansion grooves 2013. An embedded threaded nail 2014 is provided, which passes through the rigid sleeve 2012 and extends into the first drilled hole 2011. A positioning hole 2015 is provided at the root of the embedded threaded nail 2014. A positioning nail 2016 extending to the outside is inserted and fixed inside the positioning hole 2015. A connecting ring 2017 is welded and fixed to the head of the embedded threaded nail 2014. A hoisting rope 202 is wound and fixed inside the connecting ring 2017. A safety protection structure 204 is provided through the connecting ring 2017 located on the side of the horizontal beam plate 102.

[0076] In this scheme, a reinforcing metal rod 2017 is installed inside the sleeve ring 2017 located on the side of the horizontal beam plate 102 at the bottom of the steel structure 10. A locking nail 20172 is installed inside the reinforcing metal rod 20171. The locking nail 20172 is installed inside the sleeve ring 2017. A horizontal support fixing structure 203 is installed and fixed on the outside of the reinforcing metal rod 20171.

[0077] In the movable safety operation platform of this invention, applicable to high retaining walls, when installing and assembling the horizontal support fixing structure 203, a first drill hole 2011 is first drilled at a designated location using a drilling rig, and a rigid sleeve 2012 is embedded inside the first drill hole 2011. Then, using equipment and tools, an embedded threaded nail 2014 is screwed into the rigid sleeve 2012. The expansion groove 2013 at the head of the rigid sleeve 2012 and the sleeve itself complete the initial positioning (longitudinal) of the embedded threaded nail 2014. Next, a positioning nail 2016 is inserted into the positioning hole 2015 at the root of the embedded threaded nail 2014 to perform a secondary positioning (horizontal) of the embedded threaded nail 2014, ensuring that the embedded threaded nail 2014 will not fall off due to the tension of the hoisting rope 202, thus ensuring high safety and stability.

[0078] The reinforcing metal rod 20171, which runs through the inner side, can be installed through the design of the sleeve ring 2017, and the position of the reinforcing metal rod 20171 can be limited and fixed by inserting the locking nail 20172.

[0079] For details, please refer to the following: Figure 9 , Figure 10 and Figure 11 The horizontal support fixing structure 203 includes an arc-shaped sleeve 2031, which abuts against the outer side of the reinforcing metal rod 20171. A recessed positioning sleeve 2032, which abuts against the other side of the reinforcing metal rod 20171, is fixed to the side of the arc-shaped sleeve 2031 by screws. The recessed positioning sleeve 2032 extends into the interior of the horizontal operating platform 2033, which is mounted on the top of the triangular support frame 30 by screws. A horizontal moving structure 205 is installed inside the horizontal operating platform 2033; elastic pad 2. 034, the elastic gasket 2034 is set on the outside of the concave positioning sleeve 2032, and the top of the elastic gasket 2034 abuts against the pressing fixing block 2035. The pressing fixing block 2035 is fixed inside the horizontal operating platform 2033 by screws. The left and right sides of the top of the horizontal operating platform 2033 are installed and fixed with the hoisting fixing unit 2036. The hoisting fixing unit 2036 installs and fixes the hoisting rope 202 inside, and completes the automatic hoisting and unhoisting operation of the hoisting rope 202 through the automatic winding and unwinding system inside.

[0080] In the movable safety operating platform of the present invention, applicable to high retaining walls, the arc-shaped sleeve 2031 and the concave positioning sleeve 2032 are installed by screws, and the concave positioning sleeve 2032 is assembled with the horizontal operating platform 2033 by the pressing fixing block 2035. The horizontally positioned horizontal operating platform 2033 is then installed to the side of the steel structure 10. The elastic gasket 2034 between the concave positioning sleeve 2032 and the pressing fixing block 2035 absorbs mechanical vibration, reduces structural resonance, eliminates gaps, and improves the tightness of the connection between the concave positioning sleeve 2032 and the pressing fixing block 2035.

[0081] For details, please refer to the following: Figure 9 The safety protection structure 204 includes a locking buckle 2041, which is installed and wound around the outside of the hoisting rope 202. A safety steel rope 2042 is connected to the root of the locking buckle 2041, and the safety steel rope 2042 passes through the connecting ring 2017. A limiting sleeve 2043 is fixed to the front of the horizontal beam 102 by screws. The safety steel rope 2042 is installed inside the limiting sleeve 2043 and extends into the interior of the steel rope winding and unwinding device 2044. The steel rope winding and unwinding device 2044 is installed on the front of the horizontal beam 102 by screws. The steel rope winding and unwinding device 2044 uses an internal self-locking system to install and position the safety steel rope 2042 in the winding and unwinding state.

[0082] In the movable safety operation platform of this invention, applicable to high retaining walls, the winding and unwinding operation of the safety steel rope 2042 by the steel rope winding and unwinding device 2044 allows for lateral pulling on the hoisting rope 202 connected to the bottom of the safety steel rope 2042 via the locking buckle 2041, thereby increasing the tensile strength and service life of the hoisting rope 202. Simultaneously, the hoisting rope 202, the safety steel rope 2042, and the horizontal beam 102 form a triangular structure, ensuring the strength of the hoisting rope 202 and preventing its breakage, thus enhancing safety.

[0083] For details, please refer to the following: Figure 12 , Figure 13 and Figure 14The horizontal moving structure 205 includes a linear motor 2051, which is mounted on one side of the top of the horizontal operating platform 2033. The output end of the linear motor 2051 is connected to a first gear 2052, and the bottom of the first gear 2052 is meshed with a second gear 2053. Both the first gear 2052 and the second gear 2053 are rotatably connected to the inner wall of the horizontal operating platform 2033. An intermediate reciprocating screw 2054 is connected to the second gear 2053 and rotatably connected to the center inside the horizontal operating platform 2033. The outer side of the intermediate reciprocating screw 2054 is connected via ball bearings. A horizontal slider 2055 is provided, and a lower base plate 2056 is fixed to the top of the horizontal slider 2055 by screws. A work protection structure 207 is fixed to the top of the lower base plate 2056 by screws. A tooth limiting structure 206 located on the side of the middle reciprocating lead screw 2054 is installed on the side of the lower base plate 2056. A guide seat 2057 is fixed to the left and right sides of the bottom of the lower base plate 2056 by screws. The guide seat 2057 is slidably connected to the outside of the horizontal guide rail 2058. The horizontal guide rail 2058 is installed inside the horizontal operating platform 2033 and is located on the left and right sides of the middle reciprocating lead screw 2054.

[0084] In the movable safety operation platform of this invention, applicable to high retaining walls, when construction is carried out at different locations, the linear motor 2051 is activated, driving the first gear 2052 connected to the output end of the linear motor 2051 to rotate, which in turn drives the second gear 2053 meshing with the first gear 2052 to rotate. When the second gear 2053 rotates, it drives the intermediate reciprocating screw 2054 connected to the second gear 2053 to rotate, causing the horizontal slider 2055 and the lower base plate 2056 connected by ball bearings on the outside of the intermediate reciprocating screw 2054 to operate. When the lower base plate 2056 operates, the guide seats 2057 installed on both sides of its bottom slide on the outside of the horizontal guide rail 2058, guiding the movement of the lower base plate 2056 and ensuring the stability of the lower base plate 2056 during movement.

[0085] For details, please refer to the following: Figure 14The toothed limiting structure 206 includes a transmission gear 2061, which is rotatably connected to one side of the bottom of the lower base plate 2056. A horizontal toothed rod 2062 is meshed with the side of the transmission gear 2061. The horizontal toothed rod 2062 is installed inside the horizontal operating platform 2033 and is located between the intermediate reciprocating lead screw 2054 and the horizontal guide rail 2058. A one-way groove 2063 is formed inside the shaft end of the transmission gear 2061. A limiting block 2064 extending to the outside is provided inside the one-way groove 2063. The limiting block 2064 is connected to the output end of the vertical electric cylinder 2065. The vertical electric cylinder 2065 is installed and fixed on the side of the work protection structure 207.

[0086] In this design, the limiting block 2064 has multiple outward protrusions 20641 on its outer side. The limiting block 2064 matches the one-way groove 2063 through the protrusions 20641 and limits and fixes the position of the transmission gear 2061.

[0087] In the movable safety operation platform of the present invention, applicable to high retaining walls, after the relocation is completed, the operation of the vertical electric cylinder 2065 can drive the limiting block 2064 connected to the output end of the vertical electric cylinder 2065 to extend into the interior of the one-way groove 2063. At this time, the rotation of the transmission gear 2061 is restricted by the locking positioning of the one-way groove 2063 and the limiting block 2064 (by the protrusion 20641), ensuring that the transmission gear 2061 will not rotate.

[0088] When the equipment is moved, the limiting and fixing of the transmission gear 2061 is released. At this time, the transmission gear 2061 can engage with the side of the horizontal toothed rod 2062 to guide the horizontal movement of the lower base plate 2056.

[0089] For details, please refer to the following: Figure 12 The work protection structure 207 includes a Z-shaped work platform 2071, which is fixed to the top of the lower base plate 2056 by screws. The Z-shaped work platform 2071 has a temporary storage cavity 2072 inside and a ramp 2073 on the side of the temporary storage cavity 2072. A vertical electric cylinder 2065 is fixed to one side of the Z-shaped work platform 2071. A protective net 2074 is installed at the edge of the top of the Z-shaped work platform 2071.

[0090] In the movable safety operation platform of this invention, suitable for tall retaining walls, building materials are planned and distributed in different locations within the temporary storage chamber 2072, while maintaining space for normal activities of construction personnel. The protective netting 2074 ensures the safety of construction personnel during their activities. Example 2

[0091] For details, please refer to the following: Figure 15 A one-way ratchet 40 is installed on the outer side of the bottom of the reciprocating screw 2054. The one-way ratchet 40 is rotatably connected to one side of the inner wall of the horizontal operating platform 2033. The teeth of the one-way ratchet 40 abut against a one-way stop 401. One side of the one-way stop 401 is vertically set, and the other side is set obliquely. The obliquely set one-way stop 401 matches the teeth of the one-way ratchet 40. The one-way stop 401 is connected to the output end of the positioning electric push rod 402. The positioning electric push rod 402 is installed and fixed on the inner wall of the horizontal operating platform 2033.

[0092] In the movable safety operating platform of the present invention applicable to high retaining walls, the output end one-way stop 401 can be moved by the positioning electric push rod 402 to control whether the one-way stop 401 and the one-way ratchet 40 are in a meshing state. This restricts the rotation of the one-way ratchet 40 and the intermediate reciprocating screw 2054, ensuring that the intermediate reciprocating screw 2054 can only rotate in one direction. This avoids the problem of the Z-shaped operating platform 2071 moving due to the weight of the material on the Z-shaped operating platform 2071, and improves the safety of construction personnel during construction.
