Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a clamp construction platform. Background Technology

[0002] In the field of building construction, different construction stages often require operations at different heights, such as the construction of cap beams in bridge construction, the construction of piers for viaducts, and the construction of circular concrete columns for large stadiums. However, traditional construction platforms have significant limitations in height adjustment. Height adjustment is difficult and cumbersome, requiring a lot of time and manpower for setup and dismantling, which seriously affects construction efficiency and increases construction costs.

[0003] Specifically, the height adjustment of traditional construction platforms usually relies on the erection of scaffolding or the use of aerial work platforms. For example, in bridge construction, the erection of scaffolding not only requires a large amount of materials, but also has strict requirements on the foundation. The installation and dismantling process is time-consuming and labor-intensive, and poses safety hazards.

[0004] For example, the clamp-type safety operating platform mentioned in patent application number CN201620902835.0, while improving construction safety to some extent, still relies on scaffolding for height adjustment and cannot quickly adapt to construction needs at different heights. Furthermore, while aerial work platforms offer a more flexible height adjustment method, their use is limited by site conditions and they are difficult to deploy in areas with high heights or dense piers. Moving and adjusting their position is also inconvenient, leading to low construction efficiency. Similarly, the clamp-type operating platform for elevated bridge construction described in patent application number CN201821932021.7, although improving formwork height adjustment through clamps and a jack system, still does not solve the problem of rapid overall height adjustment of the construction platform.

[0005] Based on this, the present invention proposes a novel clamp construction platform. The present invention aims to solve the problem of difficult height adjustment of traditional construction platforms, and realize the rapid and flexible adjustment of the height of the construction platform. This not only significantly reduces the time and labor costs required for height adjustment, but also improves the adaptability and versatility of the construction platform, enabling it to be quickly adjusted to the optimal working position under different heights and different construction scenarios, thereby greatly improving construction efficiency and reducing construction costs.

[0021] The technical solution of the present invention will now be described with reference to the accompanying drawings. However, the described embodiments are only some embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 6 As shown, the present invention provides a clamp construction platform, including a clamp 2 fastened to a pier column, and a lifting platform device 3 set on the clamp 2, and a crawling lifting device 1 for pushing the clamp 2 is set below the clamp 2. The lifting platform device 3 includes two foldable platform lifting units 31. Each platform lifting unit 31 includes a main support beam 311 connecting the clamp 2. At both ends of the main support beam 311, there are insertion positioning rods 312 and insertion interfaces 313 for receiving the insertion positioning rods 312. The insertion interfaces 313 are provided with insertion locking devices 314 for locking the insertion positioning rods 312. Both ends of the main support beam 311 extend downward to form lifting support beams 315. An adjustment auxiliary device 316 is provided between the lifting support beams 315 of the two platform lifting units 31. A platform adjustment device 317 is fixedly connected to the lifting support beams 315, and a construction platform 318 is flexibly connected to it through the platform adjustment device 317.

[0023] Specifically, the main support beam 311 is made of high-strength steel, is long and narrow, and has sufficient rigidity and strength to bear the weight of the construction platform 318 and the personnel and equipment on it. Its length is determined according to the scale and design requirements of the construction platform 318, and both ends are finely machined and respectively equipped with plug-in positioning rods 312 and plug-in interfaces 313.

[0024] In this embodiment, the main support beam 311 serves as the core connecting component of the platform lifting unit 31. One end is securely connected to the clamp 2 through a specific connection method, transferring the load of the entire platform lifting unit 31 to the clamp 2 and the crawling lifting device 1. The other end has a plug-in positioning rod 312 and a plug-in interface 313 for splicing with other platform lifting units 31 to achieve the combination of multiple platform lifting units 31, thereby expanding the working area of ​​the construction platform 318.

[0025] The high-strength materials and reasonable structural design ensure that the main support beam 311 will not deform or be damaged when subjected to large loads, thus guaranteeing the structural stability and safety of the platform lifting unit 31. Precise machining processes result in high precision in the fit between the plug-in positioning rod 312 and the plug-in interface 313, facilitating the quick and accurate assembly of multiple platform lifting units 31.

[0026] Specifically, the lifting support beam 315 is also made of high-strength steel and is vertically connected to the main support beam 311, forming an "L" shape. Its length is determined according to the design height of the construction platform 318 and the installation requirements of the adjustment auxiliary device 316, and its surface is treated with rust prevention to improve its service life.

[0027] The lifting support beam 315 provides an installation foundation for the distance adjustment auxiliary device 316 and the platform adjustment device 317, and transfers the weight of the construction platform 318 to the clamp 2 and the crawling lifting device 1 through the main support beam 311. At the same time, the lifting support beam 315 also enhances the overall structural strength of the platform lifting unit 31 and improves the stability of the platform during the lifting process.

[0028] The "L"-shaped structural design and the use of high-strength steel enable the lifting support beam 315 to withstand larger bending moments and torques, effectively distributing the load transmitted from the construction platform 318 and ensuring that the platform lifting unit 31 will not deform or be damaged during the lifting process. Rust prevention treatment extends the service life of the lifting support beam 315 and reduces maintenance costs.

[0029] like Figures 1 to 3 As shown, in this embodiment, a plug-in locking tooth 3121 is provided on the plug-in positioning rod 312, and the plug-in locking device 314 includes a plug-in damping device 3143 and a rack locking device respectively provided on both sides of the plug-in interface 313. The plug-in damping device 3143 includes a damping gear 3144 that meshes with the plug-in locking tooth 3121 and a damping motor 3145 that connects to the damping gear 3144. The rack and pinion locking device includes a rack 3141 corresponding to the insertion tooth 3121, and a locking drive motor 3142 that drives the rack 3141 to engage with or move away from the insertion tooth 3121.

[0030] Specifically, the insertion positioning rod 312 is cylindrical or square-shaped, with a polished surface to reduce resistance when inserted into the insertion interface 313. Its end is provided with insertion teeth 3121, which are evenly distributed wedge-shaped to facilitate engagement with the insertion locking device 314 for locking. The insertion interface 313 is a cylindrical hole that matches the insertion positioning rod 312, and has an internal groove for installing the insertion locking device 314.

[0031] In this embodiment, the insertion positioning rod 312 is inserted into the corresponding insertion interface 313 when the two platform lifting units 31 are spliced, playing a role in initial positioning and connection, ensuring accurate alignment of the two platform lifting units 31 in the horizontal direction. The insertion locking teeth 3121 interact with the insertion locking device 314 to prevent the insertion positioning rod 312 from coming out of the insertion interface 313 due to vibration or external force during construction.

[0032] Among them, the precise size design and reasonable tooth structure make the connection between the plug-in positioning rod 312 and the plug-in interface 313 tight and reliable, which can effectively withstand various loads during construction and ensure the stability of the two platform lifting units 31 after splicing.

[0033] Specifically, the plug-in damping device 3143 includes a damping gear 3144 and a damping motor 3145. The damping gear 3144 is a high-precision gear with a reasonable tooth profile design, which can mesh well with the plug-in locking teeth 3121. The damping motor 3145 is a small DC motor with stable speed and moderate torque, and is connected to the damping gear 3144 through a coupling.

[0034] When the insertion positioning rod 312 is inserted into the insertion interface 313, the insertion locking teeth 3121 mesh with the damping gear 3144. After the damping motor 3145 starts, it generates a certain damping force on the insertion positioning rod 312 through the damping gear 3144. This damping force can prevent the insertion positioning rod 312 from loosening due to vibration or other factors during construction, thus enhancing the stability of the connection.

[0035] Among them, the damping motor 3145 can precisely control the magnitude of the damping force according to actual needs, ensuring that the plug-in positioning rod 312 is properly damped without affecting the ease of splicing and disassembly due to excessive damping force. High-precision gear meshing ensures smooth and reliable transmission of damping force.

[0036] Specifically, the rack and pinion locking device includes a pinion rack 3141 and a locking drive motor 3142. The pinion rack 3141 is elongated, and its tooth profile matches that of the pinion teeth 3121, enabling it to perform linear motion under the drive of the locking drive motor 3142. The locking drive motor 3142 is a stepper motor, characterized by high positioning accuracy and convenient control, and is connected to the pinion rack 3141 via a lead screw and nut mechanism.

[0037] In this embodiment, after the two platform lifting units 31 are assembled, the locking drive motor 3142 is started, driving the insertion rack 3141 to move and engage with the insertion teeth 3121, further locking the insertion positioning rod 312. When it is necessary to disassemble the two platform lifting units 31, the locking drive motor 3142 rotates in the opposite direction, driving the insertion rack 3141 away from the insertion teeth 3121, releasing the locking state.

[0038] The precise control of the stepper motor allows for accurate control of the movement distance and position of the insertion rack 3141, ensuring the accurate engagement and disengagement of the insertion rack 3141 and the insertion locking tooth 3121. The lead screw and nut mechanism has a self-locking function, preventing movement of the insertion rack 3141 due to external forces after it engages with the insertion locking tooth 3121, thus ensuring the reliability of the locking effect.

[0039] like Figure 5 and Figure 6 As shown, in this embodiment, the distance adjustment auxiliary device 316 includes an auxiliary rod group disposed between the lifting support beams 315 of the two platform lifting units 31. The auxiliary rod group includes two auxiliary support rods 3161 that are rotatably connected in an "X" shape. The lifting support beam 315 is provided with an adjustment groove 3162 for at least part of the auxiliary support rod 3161. The bottom end of the auxiliary support rod 3161 is hinged to the bottom of the adjustment groove 3162. An adjustment slide rod 3163 is provided at the upper end of the adjustment groove 3162. An auxiliary slider 3164 is rotatably connected to the top of the auxiliary support rod 3161. The auxiliary slider 3164 is slidably connected to the adjustment slide rod 3163. An auxiliary locking device 3165 is provided between the two auxiliary support rods 3161.

[0040] Specifically, the auxiliary rod assembly consists of two auxiliary support rods 3161 rotatably connected in an "X" shape. The auxiliary support rods 3161 are made of lightweight, high-strength alloy material, featuring both light weight and high strength. The two auxiliary support rods 3161 are connected at the middle via a hinge shaft, allowing them to rotate freely around the hinge shaft.

[0041] In this embodiment, the auxiliary rod assembly acts as a buffer and stabilizer when adjusting the distance between the two platform lifting units 31. When the two platform lifting units 31 move closer or further apart, the auxiliary support rod 3161 rotates around the hinge axis, absorbing some energy through its elastic deformation, thus preventing structural damage or shaking of the construction platform 318 due to excessively rapid distance adjustment or uneven force.

[0042] The use of lightweight, high-strength alloy materials makes the auxiliary rod assembly lightweight, easy to install and operate, while ensuring sufficient strength to withstand the load during the adjustment process. The "X"-shaped structure design and reasonable elastic deformation characteristics enable the auxiliary rod assembly to effectively buffer and stabilize the distance adjustment process of the two platform lifting units 31, improving the safety and stability of the construction platform 318.

[0043] Specifically, the adjustment groove 3162 is provided on the lifting support beam 315 and is a rectangular groove. Its width and depth are designed according to the size and installation requirements of the auxiliary support rod 3161. The surface of the adjustment groove 3162 is smoothed to reduce the friction of the auxiliary support rod 3161 during movement.

[0044] In this embodiment, the adjusting groove 3162 provides space for the installation and movement of the auxiliary support rod 3161. The bottom end of the auxiliary support rod 3161 is hinged to the bottom of the adjusting groove 3162, allowing the auxiliary support rod 3161 to rotate about the hinge point as an axis, thus realizing the distance adjustment function. At the same time, the adjusting groove 3162 also limits the range of movement of the auxiliary support rod 3161, preventing the auxiliary support rod 3161 from exceeding the safe range during adjustment.

[0045] The precise dimensional design and smooth surface treatment allow the auxiliary support rod 3161 to move smoothly within the adjusting groove 3162, reducing the impact of friction on the adjustment process. The reasonable depth and width design of the adjusting groove 3162 ensures the stability of the auxiliary support rod 3161 during the adjustment process, preventing the auxiliary support rod 3161 from affecting the accuracy of distance adjustment due to shaking.

[0046] Specifically, the adjusting slide bar 3163 is cylindrical, made of high-strength steel, and chrome-plated, giving it high hardness and wear resistance. The auxiliary slider 3164 is a square block with a central hole that matches the adjusting slide bar 3163, allowing it to slide freely on the adjusting slide bar 3163. The auxiliary slider 3164 is connected to the top of the auxiliary support rod 3161 via a hinge.

[0047] In this embodiment, when it is necessary to adjust the distance between the two platform lifting units 31, the auxiliary slider 3164 is driven to slide on the adjusting slide bar 3163, thereby rotating the auxiliary support rod 3161 and adjusting the distance between the two platform lifting units 31. The adjusting slide bar 3163 provides guidance and support for the sliding of the auxiliary slider 3164, ensuring the straightness and stability of the sliding of the auxiliary slider 3164.

[0048] The high-strength steel and chrome plating give the adjusting slide bar 3163 high strength and wear resistance, enabling it to withstand the friction and load generated during the sliding of the auxiliary slider 3164, ensuring long-term reliability. The precise fit between the auxiliary slider 3164 and the adjusting slide bar 3163, along with the hinged connection, allows the auxiliary support rod 3161 to rotate accurately as the auxiliary slider 3164 slides, achieving precise adjustment of the distance between the two platform lifting units 31.

[0049] Specifically, the auxiliary locking device 3165 is disposed between the two auxiliary support rods 3161, and can be locked by bolts or hydraulic locking. The bolt locking method involves fixing the two auxiliary support rods 3161 together using bolts through corresponding bolt holes on the two auxiliary support rods 3161. The hydraulic locking method involves installing a hydraulic cylinder on the auxiliary support rods 3161, and locking and unlocking the two auxiliary support rods 3161 by extending or retracting the piston rod of the hydraulic cylinder.

[0050] In this embodiment, after the distance between the two platform lifting units 31 is adjusted to the correct position, the auxiliary locking device 3165 is activated to fix the two auxiliary support rods 3161 in the current position, preventing the distance from changing due to external forces during construction and ensuring the stability of the construction platform 318.

[0051] Among them, the bolt locking method has a simple structure, low cost, and convenient operation, which can meet the locking requirements of general construction scenarios; the hydraulic locking method has a large locking force and reliable locking, and can achieve fast locking and unlocking, making it suitable for construction scenarios with high requirements for locking accuracy and reliability.

[0052] like Figure 5 and Figure 6 As shown, in this embodiment, the platform adjustment device 317 includes a lifting adjustment beam 3171 fixedly mounted on the lifting support beam 315. The lifting adjustment beam 3171 is provided with a lifting adjustment groove 3172. The lifting adjustment groove 3172 is provided with a lifting threaded rod 3173 and a lifting drive motor 3174 that drives the lifting threaded rod 3173 to rotate. The construction platform 318 is provided with a base 3175 for connecting the lifting threaded rod 3173. The base 3175 is provided with a lifting hole 3176 corresponding to the lifting threaded rod 3173. The construction platform 318 is fitted with the lifting threaded rod 3173 through the lifting hole 3176. A lifting jacking block 3177 for pushing the construction platform 318 is provided below the base 3175. The lifting jacking block 3177 is provided with a lifting threaded hole 3178 corresponding to the lifting threaded rod 3173. The lifting threaded hole 3178 is threadedly connected to the lifting threaded rod 3173. The platform adjustment device 317 adjusts the height of the construction platform 318 through the lifting threaded rod 3173, the lifting drive motor 3174, and the lifting jacking block 3177.

[0053] Specifically, the lifting adjustment beam 3171 is fixedly mounted on the lifting support beam 315, and is made of rectangular steel tubing, possessing high strength and rigidity. The length of the lifting adjustment beam 3171 is determined according to the design height of the construction platform 318 and the requirements for opening the lifting adjustment groove 3172, and its surface is treated with rust prevention.

[0054] In this embodiment, the lifting adjustment beam 3171 provides an installation base for the lifting adjustment groove 3172, securely connects the platform adjustment device 317 to the lifting support beam 315, and transfers the weight of the construction platform 318 to the lifting support beam 315.

[0055] The rectangular steel tube structure and its reasonable size selection enable the lifting and adjusting beam 3171 to withstand large loads, ensuring the stability of the platform adjusting device 317 during operation. Rust prevention treatment extends the service life of the lifting and adjusting beam 3171 and reduces maintenance costs.

[0056] Specifically, the lifting adjustment groove 3172 is installed on the lifting adjustment beam 3171 and is a rectangular groove. Its width and depth are designed according to the dimensions of the lifting threaded rod 3173 and the base 3175 of the construction platform 318. The lifting adjustment groove 3172 is equipped with a guide rail inside to guide the lifting movement of the base 3175 of the construction platform 318.

[0057] In this embodiment, the lifting adjustment groove 3172 provides installation and movement space for the lifting threaded rod 3173 and the base 3175 of the construction platform 318. The guide rail ensures the straightness and stability of the base 3175 of the construction platform 318 during the lifting process, and prevents the construction platform 318 from shaking or deviating during the lifting process.

[0058] Among them, the precise size design and the setting of the guide rail enable the base 3175 of the construction platform 318 to rise and fall accurately and stably within the lifting adjustment groove 3172, thereby improving the accuracy and safety of the height adjustment of the construction platform 318.

[0059] Specifically, the lifting threaded rod 3173 is a trapezoidal threaded rod made of high-strength alloy steel, possessing high strength and wear resistance. Both ends of the threaded rod are mounted on the top and bottom of the lifting adjustment groove 3172 via bearings, ensuring free rotation of the threaded rod. The lifting drive motor 3174 is a servo motor, characterized by stable speed and high control precision, and is connected to the lifting threaded rod 3173 via a coupling.

[0060] In this embodiment, the lifting drive motor 3174 drives the lifting threaded rod 3173 to rotate. The lifting threaded rod 3173 converts the rotational motion into linear motion through a threaded connection, thereby driving the base 3175 of the construction platform 318 to rise and fall, thus realizing the adjustment of the height of the construction platform 318.

[0061] The trapezoidal threaded rod has a self-locking function, which prevents the base 3175 of the construction platform 318 from sliding down due to gravity when the lifting drive motor 3174 stops rotating, ensuring the stability of the construction platform 318 after adjustment. The precise control of the servo motor enables accurate control of the rotation speed and direction of the lifting threaded rod 3173, thereby achieving precise adjustment of the height of the construction platform 318.

[0062] Specifically, the base 3175 of the construction platform 318 is a rectangular steel plate, the dimensions of which are designed according to the size of the construction platform 318 and the size of the lifting adjustment groove 3172. The base 3175 is provided with a lifting hole 3176 corresponding to the lifting threaded rod 3173. A nut matching the lifting threaded rod 3173 is installed in the lifting hole 3176, and a threaded connection is achieved between the nut and the lifting threaded rod 3173. A lifting jacking block 3177 for pushing the construction platform 318 is provided below the base 3175.

[0063] In this embodiment, the lifting threaded rod 3173 is connected to the lifting hole 3176 and nut, transmitting the linear motion of the lifting threaded rod 3173 to the construction platform 318 and providing a supporting foundation for the construction platform 318. The lifting jacking block 3177 is used to jack the construction platform 318, enabling the construction platform 318 to rise and fall together with the base 3175.

[0064] Specifically, the rectangular steel plate's structural design and reasonable dimensional selection ensure that the base 3175 of the construction platform 318 has sufficient strength and rigidity to support the weight of the construction platform 318. The precise fit between the nut and the lifting threaded rod 3173 guarantees the smoothness and reliability of the lifting movement. The design of the lifting jacking block 3177 ensures that the construction platform 318 receives a uniform jacking force during the lifting process, preventing the construction platform 318 from tilting or being damaged due to uneven force distribution.

[0065] Specifically, the lifting jacking block 3177 is a square block made of high-strength steel. It is provided with a lifting threaded hole 3178 corresponding to the lifting threaded rod 3173, and the lifting threaded hole 3178 is threadedly connected to the lifting threaded rod 3173. The surface of the jacking block is smoothed to reduce the friction between it and the construction platform 318.

[0066] In this embodiment, when the lifting threaded rod 3173 rotates, the lifting jacking block 3177 is threadedly connected to the lifting threaded rod 3173 through the lifting threaded hole 3178, and moves linearly along the lifting threaded rod 3173, thereby pushing the construction platform 318 to achieve height adjustment. At the same time, the lifting jacking block 3177 can also bear part of the load transmitted from the construction platform 318, reducing the burden on the base 3175 of the construction platform 318.

[0067] The use of high-strength steel enables the lifting jacking block 3177 to withstand greater jacking force and load, ensuring stability and reliability during the jacking process of the construction platform 318. The smooth surface treatment reduces friction between the block and the construction platform 318, making the jacking process smoother and improving the efficiency of height adjustment of the construction platform 318.

[0068] like Figures 1 to 4As shown, in this embodiment, connecting components are provided at both ends of the construction platform 318. The connecting components include connecting slots 3181 fixedly provided at both ends of the construction platform 318, and supporting connecting rods 3182 and platform connecting plates 3183 provided between the two construction platforms 318. The supporting connecting rods 3182 are provided with connecting pins 3184 corresponding to the connecting slots 3181 at both ends. Connecting positioning strips 3185 corresponding to the platform connecting plates 3183 are provided on the construction platform 318. The platform connecting plates 3183 are mounted on the supporting connecting rods 3182.

[0069] like Figures 1 to 4 As shown, in this embodiment, a construction guardrail 3186 is provided on the construction platform 318. Guardrail connecting components are provided at both ends of the construction guardrail 3186 of the two construction platforms 318. The guardrail connecting components include a first guardrail slot 3187 provided at both ends of the construction guardrail 3186 and a second guardrail slot 3188 provided at both ends of the construction platform 318. A connecting guardrail 3189 is provided between the construction guardrails 3186 of the two construction platforms 318. A first guardrail pin 3190 and a second guardrail pin 3191 are provided at both ends of the connecting guardrail 3189, respectively corresponding to the first guardrail slot 3187 and the second guardrail slot 3188.

[0070] Specifically, the connecting bayonet 3181 is fixedly installed at both ends of the construction platform 318, and has a rectangular groove structure. The size of the groove is designed according to the size of the connecting pin 3184 of the supporting connecting rod 3182. The connecting bayonet 3181 has a positioning pin hole inside for installing positioning pins to improve the positioning accuracy of the connection.

[0071] In this embodiment, the connecting slot 3181 provides a positioning and fixing point for the connecting pin 3184 of the supporting connecting rod 3182. The initial connection between the supporting connecting rod 3182 and the construction platform 318 is achieved by inserting the connecting pin 3184 into the connecting slot 3181. The cooperation between the positioning pin hole and the positioning pin further improves the positioning accuracy of the connection, preventing the supporting connecting rod 3182 from shaking or shifting during construction.

[0072] The rectangular groove structure and precise dimensional design allow the connecting pin 3184 to be accurately and securely inserted into the connecting bayonet 3181, ensuring the reliability and stability of the connection between the support connecting rod 3182 and the construction platform 318. The positioning pin holes and positioning pins improve the positioning accuracy of the connection, enabling multiple construction platforms 318 to be accurately aligned during splicing, ensuring the overall flatness and stability of the construction platform 318.

[0073] Specifically, the support connecting rod 3182 has connecting pins 3184 at both ends, corresponding to connecting slots 3181. The connecting pins 3184 are cylindrical, and their diameter matches the size of the connecting slots 3181. The main body of the support connecting rod 3182 is made of high-strength steel pipe, possessing sufficient strength and rigidity to withstand the load transmitted from the construction platform 318. Both ends of the steel pipe are connected to the connecting pins 3184 by welding; the welding quality undergoes rigorous testing to ensure a firm and reliable connection.

[0074] In this embodiment, the connecting pin 3184 is inserted into the connecting slot 3181 to connect the supporting connecting rod 3182 to the construction platform 318, thus supporting and connecting the two construction platforms 318. At the same time, the supporting connecting rod 3182 can also transfer and distribute the load between the two construction platforms 318, enhancing the stability of the entire construction platform 318 structure.

[0075] The use of high-strength steel pipes enables the support connecting rod 3182 to withstand large loads, ensuring that it will not deform or be damaged during construction. The precise size design of the connecting pin 3184 and the robust welding connection method ensure that the connection between the support connecting rod 3182 and the construction platform 318 is tight and reliable, effectively transferring and distributing loads and improving the overall stability of the construction platform 318.

[0076] Specifically, the platform connecting plate 3183 is mounted on the support connecting rod 3182, and the construction platform 318 is provided with a corresponding connecting positioning strip 3185 for the platform connecting plate 3183. The platform connecting plate 3183 is positioned and fixed by the connecting positioning strip 3185, which further enhances the connection strength between the two construction platforms 318 and ensures that the construction platform 318 will not separate due to force during construction.

[0077] In this embodiment, a construction guardrail 3186 is provided on the construction platform 318 to provide safety protection for construction personnel. Guardrail connecting components are provided at both ends of the construction guardrails 3186 of the two construction platforms 318 to connect the construction guardrails 3186 of the two construction platforms 318 into a whole, thereby improving the continuity of safety protection.

[0078] The guardrail connection assembly includes a first guardrail latch 3187 and a second guardrail latch 3188. The first guardrail latch 3187 and the second guardrail latch 3188 are respectively set at both ends of the construction guardrail 3186 and both ends of the construction platform 318, providing positioning and fixing points for the connection of the guardrail 3189.

[0079] The guardrail 3189 is equipped with a first guardrail pin 3190 and a second guardrail pin 3191 at both ends, corresponding to the first guardrail slot 3187 and the second guardrail slot 3188 respectively. By inserting the first guardrail pin 3190 and the second guardrail pin 3191 into the first guardrail slot 3187 and the second guardrail slot 3188 respectively, the construction guardrails 3186 of the two construction platforms 318 are connected, forming a complete safety protection system to ensure the safety of construction personnel.

[0080] like Figures 1 to 4 As shown, in this embodiment, a connecting block 21 is provided on the clamp 2, and a connecting positioning groove 211 corresponding to the main support beam 311 is provided on the connecting block 21. The clamp 2 includes two clamp units 22 that cooperate with each other. A connecting fixing hole (not shown in the figure) is provided at both ends of the clamp unit 22. A fixing connecting bolt 24 corresponding to the connecting fixing hole is provided at the lower end of the connecting block 21. A crossbeam locking bolt 25 penetrating the main support beam 311 is provided on the connecting positioning groove 211.

[0081] Specifically, a connecting block 21 is provided on the clamp 2, which serves to connect the clamp 2 and the main support beam 311. A connecting positioning groove 211 is provided on the connecting block 21, corresponding to the main support beam 311, and is used to position the main support beam 311 to ensure that the main support beam 311 is accurately installed on the clamp 2, thereby improving installation accuracy and stability.

[0082] The clamp unit 22 includes two clamp units 22 that cooperate with each other. Both ends of the clamp unit 22 are provided with connection and fixing holes. The two clamp units 22 can be connected together through the connection and fixing holes to form a complete clamp 2, which is used to clamp a specific part on the crawling lifting device 1 and reliably fix the entire lifting platform device 3 on the crawling lifting device 1.

[0083] The fixing bolts 24 are located at the lower end of the connecting block 21, corresponding to the connecting and fixing holes at both ends of the clamp unit 22. The fixing bolts 24 are used to firmly connect the connecting block 21 and the clamp unit 22, further enhancing the connection strength between the clamp 2 and the connecting block 21.

[0084] The crossbeam locking bolt 25 is set on the connecting positioning groove 211, passes through the main support beam 311, and locks the main support beam 311 tightly with the connecting block 21 and the clamp 2, preventing the main support beam 311 from loosening or shifting due to force during construction, and ensuring the structural stability and safety of the entire clamp construction platform 318.

[0085] This invention has many applications, including but not limited to the following described scenarios: When constructing bridge piers, towers, or other structures, this clamp-type construction platform can move up and down along the piers or towers using a crawling lifting device. The clamps are securely fixed to the structure, providing a stable platform for construction workers. Workers can then perform tasks such as rebar tying, formwork installation, and concrete pouring on the platform.

[0086] Due to the large size of the bridge structure, the construction platform can be expanded using adjustable distance devices and connecting components to accommodate the construction needs of piers or towers of different sizes. Furthermore, the platform's height can be precisely adjusted according to the construction progress, facilitating work at different heights for construction personnel.
