Description

Technical Field

[0001] This utility model relates to the field of road and bridge engineering technology, specifically to a bridge pile foundation reinforcement device. Background Technology

[0002] Bridge pile foundation reinforcement devices are used to fix bridge piles to enhance the stability of the bridge pile foundation and reduce the swaying or displacement of the bridge piles under the action of external factors such as vehicle loads and geological settlement, thereby ensuring the overall safety and durability of the bridge structure.

[0003] In the prior art, a road and bridge pile foundation reinforcement device with patent publication number CN220888770U requires rotating the handles on both sides one by one during use to drive the corresponding arc-shaped contact plate to fit with the pile foundation. When the pile foundation needs to be reinforced quickly, the operation of rotating the handles one by one not only consumes a lot of time and affects the construction progress, but also makes it difficult to ensure that the arc-shaped contact plates on both sides fit with the pile foundation simultaneously and evenly. If the fit of the arc-shaped contact plates on both sides is inconsistent, it may lead to uneven stress on the pile foundation, thereby affecting the reinforcement effect. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a bridge pile foundation reinforcement device, which can effectively solve the problem that rotating the rotating handles on both sides one by one in the existing technology not only consumes a lot of time, but also makes it difficult to ensure that the arc-shaped contact plates on both sides fit with the pile foundation simultaneously and evenly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a bridge pile foundation reinforcement device, including a bearing mechanism, including a hollow plate, and a plurality of ground nails fixedly connected to the bottom of the hollow plate; The positioning mechanism includes multiple sets of contact plates for clamping and fixing bridge piles of different heights, a flipping assembly capable of driving the multiple sets of contact plates to flip simultaneously to the contact position with the bridge piles, and a drive assembly for controlling the operation of the flipping assembly. Multiple sets of contact plates are arranged in a circumferential array on the outside of the hollow disk, the flipping component is located at the center of the multiple sets of contact plates, and the driving component is located below the flipping component; The contact plate includes a fixed plate arranged in a circumferential array on the outside of the hollow disk, a telescopic plate slidably connected to the inner surface of the fixed plate, and a clamping plate integrally formed on the outer end face of the telescopic plate for clamping the bridge pile.

[0006] Furthermore, the contact plate also includes multiple springs fixedly installed on the outside of the fixed plate, an arc-shaped block fixedly connected to the other end of the spring, multiple plug-in posts fixedly connected to the inside of the arc-shaped block, and multiple sets of insertion holes penetrating the surface of the telescopic plate and used in conjunction with the plug-in posts.

[0007] Furthermore, the outer end face of the plug-in post passes through the outer side of the fixing plate and the insertion hole, and extends to the inner side of the fixing plate, with the outer surface of the plug-in post in sliding contact with the inner surface of the fixing plate; When the arc-shaped block is pulled to move the plug-in post out of the socket, the telescopic plate can be freely controlled to slide along the inner wall of the fixed plate to adjust the overall length of the contact plate.

[0008] Furthermore, the flipping assembly includes a turntable located at the center of the plurality of fixed plates, an arc groove arranged in a circumferential array and extending through the surface of the turntable, a force-bearing column movably connected to the inner wall of the arc groove, a connecting rod fixedly connected to the outer end face of the force-bearing column, and a force-applying column fixedly connected to the other end of the connecting rod.

[0009] Furthermore, the flipping assembly also includes an inclined block fixedly connected to the inner side of the fixed plate and used in conjunction with the force-applying column, a hinge block fixedly connected to the inclined block near the hollow disk, a limiting groove formed on the outer surface of the hollow disk and used in conjunction with the hinge block, and a positioning block fixedly connected to the top of the hollow disk and used in conjunction with the connecting rod.

[0010] Furthermore, the outer surface of the connecting rod slides in contact with the inner wall of the positioning block, and the hinge block is hinged to the inner wall of the limiting groove; When the turntable drives the arc groove to rotate, it can push the force-bearing column to cause the connecting rod to retract inward along the positioning block, thereby causing the connecting rod to squeeze the inclined block through the force-applying column, and then drive the fixed plate through the inclined block to flip around the connection between the hinge block and the limiting groove, and finally cause the fixed plate to drive the clamping plate to contact the bridge pile through the telescopic plate.

[0011] Furthermore, the drive assembly includes a mounting groove formed on the outer surface of the hollow disk, a rotating rod fixedly mounted on the inner wall of the mounting groove by a bearing, a first bevel gear fixedly sleeved on the outer surface of the rotating rod, a second bevel gear meshing with the outer surface of the first bevel gear, a transmission column fixedly connected to the inner surface of the second bevel gear, a spur gear fixedly sleeved on the through end of the transmission column, and a geared disc meshing with the outer surface of the spur gear and used in conjunction with the turntable.

[0012] Furthermore, a rotating bearing sleeve is installed at the connection between the transmission column and the hollow disk, and the gear disk is fixedly sleeved on the outer surface of the turntable.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: This utility model, by setting a positioning mechanism, can not only control multiple contact plates to simultaneously and evenly adhere to the pile foundation during the reinforcement of bridge piles, ensuring uniform adhesion, but also flexibly control the overall length of multiple sets of contact plates when dealing with bridge piles of different heights, thereby adapting to bridge piles of different heights.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A bridge pile foundation reinforcement device, see attached document. Figure 1 -Appendix Figure 6 ,include, The supporting mechanism 100 includes a hollow plate 110 and a plurality of ground nails 120 fixedly connected to the bottom of the hollow plate 110; The hollow disc 110 is used to provide an installation platform for the positioning mechanism 200. After the ground nail 120 is inserted into the ground, it can provide stable support for the hollow disc 110 and the entire device through the fixing effect with the ground, preventing the device from shifting as a whole during operation.

[0020] The positioning mechanism 200 includes multiple sets of contact plates 210 for clamping and fixing bridge piles of different heights, a flipping component 220 that can drive multiple sets of contact plates 210 to flip simultaneously to the contact position with the bridge piles, and a drive component 230 for controlling the operation of the flipping component 220. Multiple sets of contact plates 210 are arranged in a circular array on the outside of the hollow disk 110, the flipping component 220 is located at the center of the multiple sets of contact plates 210, and the driving component 230 is located below the flipping component 220. The contact plate 210 includes a fixed plate 211 arranged in a circumferential array on the outside of the hollow disk 110, a telescopic plate 212 slidably connected to the inner surface of the fixed plate 211, and a clamping plate 213 integrally formed on the outer end face of the telescopic plate 212 for clamping the bridge pile.

[0021] Specifically, the contact plate 210 also includes multiple springs 214 fixedly installed on the outside of the fixed plate 211, an arc-shaped block 215 fixedly connected to the other end of the springs 214, multiple plug-in posts 216 fixedly connected to the inside of the arc-shaped block 215, and multiple sets of plug holes 217 penetrating the surface of the telescopic plate 212 and used in conjunction with the plug-in posts 216.

[0022] It should be noted that the fixed plate 211 is the basic frame of the contact plate 210, which provides a sliding track for the telescopic plate 212. The telescopic plate 212 can slide along the inner wall of the fixed plate 211. By adjusting its own extension length, the overall length of the contact plate 210 can be changed to adapt to bridge piles of different heights. The clamping plate 213 is used to directly contact the surface of the bridge pile. The bridge pile is stably and evenly clamped and fixed by multiple sets of circumferentially distributed clamping plates 213. The spring 214 is used to apply an inward elastic force to the arc block 215, so that the plug pin 216 is stably inserted into the insertion hole 217 of the telescopic plate 212, thereby fixing the relative position of the telescopic plate 212 and the fixed plate 211. When the arc block 215 is pulled, the spring 214 will be stretched, and at the same time, the plug pin 216 will be moved out of the insertion hole 217, releasing the restriction on the telescopic plate 212 and facilitating the adjustment of the overall length of the contact plate 210.

[0023] Furthermore, the outer end face of the plug 216 passes through the outer side of the fixing plate 211 and the plug hole 217, and extends to the inner side of the fixing plate 211, with the outer surface of the plug 216 sliding in contact with the inner surface of the fixing plate 211. When the arc-shaped block 215 is pulled to move the plug pin 216 out of the socket 217, the telescopic plate 212 can be freely controlled to slide along the inner wall of the fixed plate 211 to adjust the overall length of the contact plate 210.

[0024] Preferably, the flipping assembly 220 includes a turntable 221 located at the center of a plurality of fixed plates 211, an arc groove 222 arranged in a circumferential array and extending through the surface of the turntable 221, a force-bearing column 223 movably connected to the inner wall of the arc groove 222, a connecting rod 224 fixedly connected to the outer end face of the force-bearing column 223, and a force-applying column 225 fixedly connected to the other end of the connecting rod 224.

[0025] It should be noted that the flipping assembly 220 also includes a ramp block 226 fixedly connected to the inner side of the fixed plate 211 and used in conjunction with the force-applying column 225, a hinge block 227 fixedly connected to the ramp block 226 on the side near the hollow disk 110, a limiting groove 228 opened on the outer surface of the hollow disk 110 and used in conjunction with the hinge block 227, and a positioning block 229 fixedly connected to the top of the hollow disk 110 and used in conjunction with the connecting rod 224.

[0026] It should be further explained that when the turntable 221 rotates, it can push the force-bearing column 223 to move through the arc groove 222. Then, multiple arc grooves 222 distributed in a circular array can synchronously drive multiple sets of force-bearing columns 223 to move, causing the force-bearing column 223 to drive the connecting rod 224 to retract inward along the positioning block 229. Then, the connecting rod 224 drives the force-applying column 225 to press the inclined block 226. The guiding effect of the inclined block is used to convert the contraction force of the connecting rod 224 into a force that pushes the fixed plate 211 to flip. Through the cooperation of the hinge block 227 and the limiting groove 228, a flipping fulcrum can be provided for the fixed plate 211, so that the fixed plate 211 can rotate around the fulcrum. Finally, the telescopic plate 212 and the clamping plate 213 are flipped to the position of contact with the bridge pile. The positioning block 229 is used to limit the sliding direction of the connecting rod 224 to ensure that the connecting rod 224 moves stably along the preset trajectory.

[0027] Furthermore, the outer surface of the connecting rod 224 slides in contact with the inner wall of the positioning block 229, and the hinge block 227 is hinged to the inner wall of the limiting groove 228. When the turntable 221 drives the arc groove 222 to rotate, it can push the force-bearing column 223 to drive the connecting rod 224 to retract inward along the positioning block 229, thereby causing the connecting rod 224 to press the inclined block 226 through the force-applying column 225, and then drive the fixed plate 211 through the inclined block 226 to flip around the connection between the hinge block 227 and the limiting groove 228, and finally cause the fixed plate 211 to drive the clamping plate 213 to contact the bridge pile through the telescopic plate 212.

[0028] Specifically, the drive assembly 230 includes a mounting groove 231 formed on the outer surface of the hollow disk 110, a rotating rod 232 fixedly mounted on the inner wall of the mounting groove 231 by bearings, a first bevel gear 233 fixedly sleeved on the outer surface of the rotating rod 232, a second bevel gear 234 meshing with the outer surface of the first bevel gear 233, a transmission column 235 fixedly connected to the inner surface of the second bevel gear 234, a spur gear 236 fixedly sleeved on the through end of the transmission column 235, and a gear disk 237 meshing with the outer surface of the spur gear 236 and used in conjunction with the turntable 221.

[0029] It should be further explained that when the rotating rod 232 is rotated, it can drive the first bevel gear 233 to rotate synchronously. The first bevel gear 233 drives the second bevel gear 234 and the transmission column 235 to rotate. Then, the transmission column 235 drives the spur gear 236, the gear disk 237 and the turntable 221 to rotate synchronously, thereby providing power for the flipping assembly 220. Then, the rope can be tied to the exposed end of the rotating rod 232, and the other end of the rope is first wrapped around the outer wall of the hollow disk 110 and tightened. Finally, the rope is folded back and cross-wound around the rotating rod 232 to form a winding structure. Finally, the end of the rope is fixed to the exposed part of the ground nail 120. The friction and tension generated by the cross-wound are utilized.

[0030] Preferably, a rotating bearing sleeve is installed at the connection between the transmission column 235 and the hollow disk 110, and the gear disk 237 is fixedly sleeved on the outer surface of the turntable 221.

[0031] When using, First, the hollow disc 110 is fitted onto the outside of the pile foundation, and the ground nail 120 is inserted into the ground. The hollow disc 110 provides stable support for the entire device. Then, the arc block 215 is pulled to stretch the spring 214, which in turn moves the plug 216 out of the insertion hole 217 of the telescopic plate 212. Next, the telescopic plate 212 is adjusted to slide along the inner wall of the fixed plate 211 to a position that matches the height of the bridge pile. Finally, the arc block 215 is released, and the spring 214 is reset to allow the plug 216 to be reinserted into the insertion hole 217, thus fixing the position of the telescopic plate 212. Rotating the rotating rod 232 drives the first bevel gear 233 to rotate. Through the cooperation of the first bevel gear 233 and the second bevel gear 234, the transmission column 235 is driven to rotate, which in turn drives the spur gear 236, the gear disk 237 and the turntable 221 to rotate synchronously. When the turntable 221 rotates: the force column 223 is pushed by the arc groove 222, causing the force column 223 to drive the connecting rod 224 to retract inward along the inner wall of the positioning block 229, thereby causing the connecting rod 224 to drive the force column 225 to squeeze the inclined block 226, driving the fixed plate 211 to flip around the connection between the hinge block 227 and the limiting groove 228, and then the fixed plate 211 drives the telescopic plate 212 and the clamping plate 213 to flip synchronously, finally making the clamping plate 213 contact the bridge pile; Finally, tie the rope to the exposed end of the rotating rod 232, then wrap the other end of the rope around the outer wall of the hollow disc 110 and tighten it. Finally, fold the rope back and cross it around the rotating rod 232 to form a winding structure. Finally, fix the end of the rope to the exposed part of the ground nail 120. The friction and tension generated by the cross winding will enhance the restraint on the rotating rod 232 and prevent it from rotating due to the reaction force of gear transmission or vibration.

[0032] In summary, by setting up the positioning mechanism 200, not only can multiple contact plates 210 be controlled to simultaneously and evenly adhere to the pile foundation during the reinforcement process of bridge piles, ensuring uniform adhesion, but also the overall length of multiple sets of contact plates 210 can be flexibly controlled when dealing with bridge piles of different heights, thereby adapting to bridge piles of different heights. This achieves the effect of significantly improving construction efficiency while enhancing the stability of bridge pile foundation reinforcement.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
