Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge construction, in particular to a hoop construction platform. BACKGROUND

[0002] In the field of building construction, different construction links often need to be operated at different heights, such as cap beam construction in bridge construction, pier column operation of viaduct, and circular concrete column construction of large venues, etc. However, the traditional construction platform has significant limitations in height adjustment, which is difficult to adjust and the adjustment process is cumbersome, requiring a lot of time and manpower to build and disassemble, which seriously affects the construction efficiency and increases the construction cost.

[0003] Specifically, the height adjustment of the traditional construction platform usually depends on the erection of scaffolding or the use of elevated vehicles. 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, and the installation and removal process is time-consuming and labor-intensive, and there are safety hazards.

[0004] As mentioned in the patent with application number CN201620902835.0, the hoop safety operation platform improves the construction safety to some extent, but still relies on the erection of scaffolding for height adjustment, and cannot quickly adapt to the construction needs of different heights. In addition, although the elevated vehicle provides a more flexible height adjustment method, its use is limited by site conditions, and it is difficult to deploy in areas with high height or dense piers, and it is not convenient to move and adjust the position, resulting in low construction efficiency. As described in the patent with application number CN201821932021.7, the hoop operation platform for viaduct construction improves the formwork height adjustment through the hoop and jack system, but still does not solve the problem of quick adjustment of the overall height of the construction platform.

[0005] Based on this, the present application proposes a brand new hoop construction platform, which aims to solve the problem of difficult height adjustment of the traditional construction platform, realize quick and flexible adjustment of the height of the construction platform, not only significantly reduce the time and labor cost required for height adjustment, but also improve the adaptability and versatility of the construction platform, so that it can quickly adjust to the best operating position in different heights and different construction scenes, thereby greatly improving the construction efficiency and reducing the construction cost.

[0032] 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.

[0033] 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.

[0034] The lifting platform device 3 comprises two platform lifting units 31 which can be folded with each other, the platform lifting unit 31 comprises a main support beam 311 connected with the hoop 2, a plug-in positioning rod 312 and a plug-in port 313 receiving the plug-in positioning rod 312 are arranged at both ends of the main support beam 311 respectively, the plug-in port 313 is provided with plug-in locking devices 314 for locking the plug-in positioning rod 312; the two ends of the main support beam 311 extend downward to form lifting support beams 315, a distance adjusting auxiliary device 316 is arranged between the lifting support beams 315 of the two platform lifting units 31; the platform adjusting device 317 is fixedly connected on the lifting support beam 315, and the construction platform 318 is connected to the platform adjusting device 317 in a lifting manner.

[0035] Specifically, the main support beam 311 is made of high-strength steel material, in a long strip shape, has sufficient rigidity and strength to bear the weight of the construction platform 318 and the personnel and equipment thereon. The length thereof is determined according to the scale and design requirements of the construction platform 318, and the two ends are finely processed to be provided with the plug-in positioning rod 312 and the plug-in port 313 respectively.

[0036] In the embodiment, the main support beam 311 serves as a core connecting component of the platform lifting unit 31, one end thereof is stably connected with the hoop 2 through a specific connecting mode, and the load of the whole platform lifting unit 31 is transmitted to the hoop 2 and the climbing lifting device 1; the plug-in positioning rod 312 and the plug-in port 313 at the other end are used for splicing with other platform lifting units 31, so as to realize the combination of multiple platform lifting units 31, and expand the working area of the construction platform 318.

[0037] Among them, the high-strength material and the reasonable structure design ensure that the main support beam 311 will not deform or be damaged when bearing a large load, and ensure the structural stability and safety of the platform lifting unit 31. The precise processing process makes the matching precision of the plug-in positioning rod 312 and the plug-in port 313 high, facilitating the quick and accurate splicing of multiple platform lifting units 31.

[0038] Specifically, the lifting support beam 315 is also made of high-strength steel material, is connected with the main support beam 311 perpendicularly, and has an "L" shape structure. The length thereof is determined according to the design height of the construction platform 318 and the installation requirements of the distance adjusting auxiliary device 316, and the surface is subjected to rust-proof treatment to improve the service life.

[0039] The lifting support beam 315 provides a mounting basis for the distance adjusting auxiliary device 316 and the platform adjusting device 317, and transmits the weight of the construction platform 318 to the hoop 2 and the climbing lifting device 1 through the main support beam 311. At the same time, the lifting support beam 315 also plays a role in enhancing the overall structural strength of the platform lifting unit 31, and improves the stability of the platform in the lifting process.

[0040] The "L" shaped structure design and the use of high-strength steel material enable the lifting support beam 315 to bear greater bending moment and torque, effectively dispersing the load transmitted by the construction platform 318, and ensuring that the platform lifting unit 31 will not be deformed or damaged during lifting.

[0041] As shown in the drawings, in the present embodiment, the plug-in positioning rod 312 is provided with a plug-in clamping tooth 3121, the plug-in locking device 314 includes a plug-in damping device 3143 and a rack locking device respectively arranged on both sides of the plug-in port 313, the plug-in damping device 3143 includes a damping gear 3144 engaging the plug-in clamping tooth 3121 and a damping motor 3145 connected to the damping gear 3144; Figures 1 to 3

[0042] The rack locking device includes a plug-in rack 3141 corresponding to the plug-in clamping tooth 3121, and a locking drive motor 3142 driving the plug-in rack 3141 to engage or move away from the plug-in clamping tooth 3121.

[0043] Specifically, the plug-in positioning rod 312 is cylindrical or square column shaped, and the surface is polished to have a certain smoothness to reduce the resistance when inserted into the plug-in port 313. The end portion is provided with the plug-in clamping tooth 3121, which is uniformly distributed in a wedge shape to facilitate cooperation with the plug-in locking device 314 to realize the locking function. The plug-in port 313 is a cylindrical hole matched with the plug-in positioning rod 312, and a recess is arranged inside for mounting the plug-in locking device 314.

[0044] In the present embodiment, the plug-in positioning rod 312 is inserted into the corresponding plug-in port 313 when the two platform lifting units 31 are spliced, playing a role of preliminary positioning and connection, ensuring the accurate alignment of the two platform lifting units 31 in the horizontal direction. The plug-in clamping tooth 3121 interacts with the plug-in locking device 314 to prevent the plug-in positioning rod 312 from being pulled out of the plug-in port 313 due to vibration or external force during construction.

[0045] Among them, the accurate size design and reasonable clamping tooth structure make the connection between the plug-in positioning rod 312 and the plug-in port 313 tight and reliable, which can effectively bear various loads during construction and ensure the stability of the two platform lifting units 31 after splicing.

[0046] 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 design and can be well engaged with the plug-in clamping tooth 3121. The damping motor 3145 is a small DC motor with stable speed and moderate torque, which is connected to the damping gear 3144 through a shaft coupling. ​

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The lifting support beam 315 is provided with a distance adjusting groove 3162 for at least partially accommodating the auxiliary support rod 3161, the bottom end of the auxiliary support rod 3161 is hinged to the bottom of the distance adjusting groove 3162, a distance adjusting slide rod 3163 is arranged at the upper end of the distance adjusting groove 3162, an auxiliary slide block 3164 is rotatably connected to the top end of the auxiliary support rod 3161, the auxiliary slide block 3164 is slidably connected to the distance adjusting slide rod 3163, and an auxiliary locking device 3165 is arranged between the two auxiliary support rods 3161.

[0054] Specifically, the auxiliary rod group is composed of two auxiliary support rods 3161 rotatably connected in an "X" shape. The auxiliary support rod 3161 is made of lightweight high-strength alloy material, which has the characteristics of light weight and high strength. The two auxiliary support rods 3161 are connected in the middle by a hinge shaft and can freely rotate around the hinge shaft.

[0055] In this embodiment, when adjusting the distance between the two platform lifting units 31, the auxiliary rod group plays a role of buffering and stabilizing. When the two platform lifting units 31 approach or move away from each other, the auxiliary support rod 3161 rotates around the hinge shaft, absorbs part of the energy through its elastic deformation, and avoids structural damage or shaking of the construction platform 318 due to too fast distance adjustment or uneven force.

[0056] Among them, the use of lightweight high-strength alloy material makes the auxiliary rod group light in weight, convenient for installation and operation, and at the same time can ensure sufficient strength to bear the load in the adjustment process. The "X" type structure design and reasonable elastic deformation characteristics make the auxiliary rod group effectively buffer and stabilize the distance adjustment process of the two platform lifting units 31, improve the safety and stability of the construction platform 318.

[0057] Specifically, the distance adjusting groove 3162 is arranged on the lifting support beam 315 and is a rectangular groove, the width and depth of which are designed according to the size and installation requirements of the auxiliary support rod 3161. The surface of the distance adjusting groove 3162 is treated to be smooth to reduce the friction of the auxiliary support rod 3161 during movement.

[0058] In this embodiment, the distance 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 distance adjusting groove 3162, so that the auxiliary support rod 3161 can rotate around the hinge point to realize the distance adjustment function. At the same time, the distance adjusting groove 3162 also limits the movement range of the auxiliary support rod 3161 to prevent the auxiliary support rod 3161 from exceeding the safe range during adjustment.

[0059] The precise size design and smooth surface treatment of the auxiliary support rod 3161 enable it to move smoothly in the distance adjustment groove 3162, reducing the influence of friction on the adjustment process. The reasonable depth and width design of the distance adjustment groove 3162 ensures the stability of the auxiliary support rod 3161 during adjustment, preventing the auxiliary support rod 3161 from shaking and affecting the accuracy of distance adjustment.

[0060] Specifically, the distance adjustment slide rod 3163 is cylindrical and made of high-strength steel with a chrome-plated surface, providing high hardness and wear resistance. The auxiliary slide block 3164 is square-shaped with a circular hole in the middle that matches the distance adjustment slide rod 3163, allowing it to slide freely on the distance adjustment slide rod 3163. The auxiliary slide block 3164 is connected to the top end of the auxiliary support rod 3161 through a hinged connection.

[0061] In this embodiment, when the distance between the two platform lifting units 31 needs to be adjusted, the auxiliary slide block 3164 is driven to slide on the distance adjustment slide rod 3163, which in turn rotates the auxiliary support rod 3161, thereby adjusting the distance between the two platform lifting units 31. The distance adjustment slide rod 3163 provides guidance and support for the sliding of the auxiliary slide block 3164, ensuring its straightness and stability.

[0062] The high-strength steel and chrome plating treatment of the distance adjustment slide rod 3163 provide high strength and wear resistance, enabling it to withstand the friction and load generated during the sliding of the auxiliary slide block 3164, ensuring long-term reliability. The precise fit of the auxiliary slide block 3164 with the distance adjustment slide rod 3163 and the hinged connection enable the auxiliary support rod 3161 to rotate accurately with the sliding of the auxiliary slide block 3164, achieving precise adjustment of the distance between the two platform lifting units 31.

[0063] Specifically, the auxiliary locking device 3165 is arranged between the two auxiliary support rods 3161 and can be locked by bolts or hydraulic locking. The bolt locking method fixes the two auxiliary support rods 3161 together using bolts by setting corresponding bolt holes on the two auxiliary support rods 3161. The hydraulic locking method installs a hydraulic cylinder on the auxiliary support rod 3161, and the locking and unlocking of the two auxiliary support rods 3161 are achieved by the extension or retraction of the piston rod of the hydraulic cylinder.

[0064] In this embodiment, after the distance between the two platform lifting units 31 is adjusted to the desired position, the auxiliary locking device 3165 is activated to fix the two auxiliary support rods 3161 in the current position, preventing changes in distance due to external forces during construction and ensuring the stability of the construction platform 318.

[0065] Among them, the bolt locking mode has simple structure, low cost, convenient operation, and can meet the locking requirements in general construction scene; the hydraulic locking mode has large locking force and reliable locking, and can realize fast locking and unlocking, and is suitable for construction scenes with high requirements on locking accuracy and reliability.

[0066] As shown in Figure 5 and Figure 6 In the embodiment, the platform adjusting device 317 includes a lifting adjusting beam 3171 fixedly arranged on the lifting support beam 315, the lifting adjusting beam 3171 is provided with a lifting adjusting groove 3172, the lifting adjusting groove 3172 is provided with a lifting threaded rod 3173 and a lifting driving motor 3174 for driving the lifting threaded rod 3173 to rotate;

[0067] The construction platform 318 is provided with a base 3175 connected with 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 sleeved with the lifting threaded rod 3173 through the lifting hole 3176, the base 3175 is provided below with a lifting pushing block 3177 for pushing the construction platform 318, the lifting pushing 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 with the lifting threaded rod 3173, and the platform adjusting device 317 adjusts the height of the construction platform 318 through the lifting threaded rod 3173 and the lifting driving motor 3174 and the lifting pushing block 3177.

[0068] Specifically, the lifting adjusting beam 3171 is fixedly arranged on the lifting support beam 315 and is made of a rectangular steel pipe, and has high strength and rigidity. The length of the lifting adjusting beam 3171 is determined according to the design height of the construction platform 318 and the opening requirement of the lifting adjusting groove 3172, and the surface is subjected to rust-proof treatment.

[0069] In the embodiment, the lifting adjusting beam 3171 provides a mounting basis for the lifting adjusting groove 3172, and stably connects the platform adjusting device 317 and the lifting support beam 315 together, and transmits the weight of the construction platform 318 to the lifting support beam 315.

[0070] The structural design and reasonable size selection of the rectangular steel pipe enable the lifting adjusting beam 3171 to bear a large load and ensure the stability of the platform adjusting device 317 during operation. The rust-proof treatment prolongs the service life of the lifting adjusting beam 3171 and reduces the maintenance cost.

[0071] Specifically, the lifting adjusting groove 3172 is arranged on the lifting adjusting beam 3171, which is a rectangular groove with a width and a depth designed according to the size of the lifting threaded rod 3173 and the base 3175 of the construction platform 318. The inside of the lifting adjusting groove 3172 is provided with a guide rail for guiding the lifting movement of the base 3175 of the construction platform 318.

[0072] In this embodiment, the lifting adjusting groove 3172 provides installation and movement space for the lifting threaded rod 3173 and the base 3175 of the construction platform 318, and the guide rail ensures the straightness and stability of the base 3175 of the construction platform 318 during lifting, preventing the construction platform 318 from shaking or deviating during lifting.

[0073] In this embodiment, the lifting adjusting groove 3172 provides installation and movement space for the lifting threaded rod 3173 and the base 3175 of the construction platform 318, and the guide rail ensures the straightness and stability of the base 3175 of the construction platform 318 during lifting, preventing the construction platform 318 from shaking or deviating during lifting.

[0074] Specifically, the lifting threaded rod 3173 is a trapezoidal threaded rod made of high-strength alloy steel, which has high strength and wear resistance. The two ends of the threaded rod are installed on the top and bottom of the lifting adjusting groove 3172 through bearings, ensuring that the threaded rod can rotate freely. The lifting drive motor 3174 is a servo motor with stable speed and high control accuracy, which is connected to the lifting threaded rod 3173 through a shaft coupling.

[0075] In this embodiment, the lifting drive motor 3174 drives the lifting threaded rod 3173 to rotate, and the lifting threaded rod 3173 converts the rotary motion into linear motion through threaded connection, thereby driving the base 3175 of the construction platform 318 to lift and adjust the height of the construction platform 318.

[0076] In this embodiment, the lifting drive motor 3174 drives the lifting threaded rod 3173 to rotate, and the lifting threaded rod 3173 converts the rotary motion into linear motion through threaded connection, thereby driving the base 3175 of the construction platform 318 to lift and adjust the height of the construction platform 318.

[0077] Specifically, the base 3175 of the construction platform 318 is a rectangular steel plate with a size designed according to the size of the construction platform 318 and the size of the lifting adjusting groove 3172.
