Description

Technical Field

[0001] This invention relates to the field of rebar tying technology, and in particular to a rebar tying structure for elevated bridge piers. Background Technology

[0002] An elevated bridge is a type of bridge that generally refers to a bridge that crosses deep ravines and canyons instead of high embankments, as well as a bridge that crosses roads in urban areas. It is supported by high-support towers or pillars. Binding is the binding of steel bars in the early stages of construction to facilitate better and safer construction. In construction, steel bars play the role of supporting and binding the elastic body of the building. A large number of steel bars need to be fixed together before pouring concrete to ensure the normal progress of subsequent work.

[0003] In the existing technology of reinforcing steel bars for viaduct piers, the steel wires in the vertical and ring bars of the steel cage are usually tied and fixed by wrapping them around the friction contact points of the vertical and ring bars using simple tying hook tools. Since there are a large number of vertical and ring bars, a lot of manpower and operation time are required. Manual high-altitude operation is highly dangerous, resulting in low efficiency of reinforcing steel bars for viaduct piers and affecting the construction progress. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A reinforced concrete pier structure for elevated bridge includes a pier cap, on which a pile foundation is fixedly mounted. A bridge main body is fixedly mounted on the pile foundation. A reinforced concrete cage is cast inside the bridge main body. The reinforced concrete cage contains vertical bars and ring bars, which are arranged in a linear, equally spaced configuration. Movable trolleys are provided at both ends of the pile foundation. A support is fixedly mounted on the top surface of the movable trolley. A slider is slidably connected to the support. A gripping mechanism is provided on the slider at the front end, and a binding assembly is provided on the slider at the rear end.

[0006] Preferably, a rack is fixed to the outer wall of the bracket, a gear is provided on the outer side of the slider, the inner end of the gear meshes with the outer side of the slider, and a fixing block is provided on both sides of the gear, with one end of the fixing block being connected and fixed to the outer wall of the bracket.

[0007] Preferably, a first servo motor is mounted on the fixed block via a mounting base, the output shaft of the first servo motor is connected and fixed to the middle of the gear, and the output shaft of the first servo motor is connected and fixed to the fixed block.

[0008] Through the above technical solution, the first servo motor drives the gear to rotate, the gear meshes with the rack, pushes the fixed block to slide along the bracket to a suitable working height, and drives the gripping mechanism and the binding assembly to move to a suitable working position.

[0009] Preferably, the gripping mechanism includes a ring block, which is rotatably connected to a slider located at the front end. A worm gear is sleeved on the lower outer wall of the ring block, and a worm is rotatably connected to the left end of the slider located at the front end.

[0010] Preferably, the right end of the worm gear is meshed with the left end of the worm wheel, and a second servo motor is mounted on the front wall of the slider at the front end via a mounting base. The output shaft of the second servo motor is coaxially connected to the front end of the worm gear.

[0011] Through the above technical solution, the second servo motor drives the worm gear to rotate, and the worm gear meshes with the worm wheel to make the ring block rotate along the slider located at the front end to the appropriate gripping position.

[0012] Preferably, a connecting block is fixedly provided on the rear wall of the annular block, a retaining seat is fixedly provided on the rear wall of the connecting block, a first cylinder is mounted on the top surface of the rear end of the connecting block via a mounting base, a retaining block is slidably connected to the rear wall of the retaining seat, and the bottom surface of the piston rod of the first cylinder is connected and fixed to the top surface of the retaining block.

[0013] Preferably, the rear wall of the card holder is provided with a plurality of trapezoidal blocks arranged in a uniform structure, and the card blocks are slidably connected to the trapezoidal blocks. The top surface of the rear end of the card holder and the bottom surface of the card blocks are engaged with the ring ribs through card slots.

[0014] The above technical solution involves placing the ring rib inside the slot of the card holder, and using the piston rod of the first cylinder to push the card block to slide downward along the trapezoidal block, thereby clamping and fixing the ring rib.

[0015] Preferably, the binding assembly includes a frame, the top surface of which has a plurality of grooves arranged in a uniform structure, and a pusher block is slidably connected inside the groove.

[0016] Preferably, the top surface of the push block is mounted with the main body of the rebar tying machine via a mounting base, the bottom surface of the push block is fixed with a movable block, and the outer wall of the movable block is mounted with a second cylinder via a mounting base.

[0017] Preferably, the piston rod of the second cylinder extends through the movable block to the inner end, the piston rod of the second cylinder is slidably connected to the movable block, and the inner wall of the piston rod of the second cylinder is fixedly connected to the outer wall of the frame.

[0018] Through the above technical solution, the piston rod of the second cylinder retracts, causing the push block to slide inward along the slide groove to a suitable working position. Then, the body of the rebar tying machine ties the friction contact points of the vertical and circular bars.

[0019] The beneficial effects of this invention are:

[0020] 1. The vertical reinforcement bars are welded and fixed to the pile foundation using external welding equipment. Then, the support frame is moved to the appropriate usage position by a mobile trolley. The first servo motor drives the gear to rotate, and the gear meshes with the rack, pushing the fixing block to slide along the support frame to the appropriate usage height. This moves the gripping mechanism and binding assembly to the appropriate usage position. After adjusting the gripping mechanism to the appropriate position for gripping the outer ring reinforcement bars, the second servo motor drives the worm gear to rotate. The worm gear meshes with the worm wheel, causing the ring block to rotate along the slider located at the front end, thus driving the connecting block. After rotating to the appropriate gripping position, the ring reinforcement is placed inside the slot of the clamping seat. The piston rod of the first cylinder pushes the clamping block to slide downwards along the trapezoidal block, clamping and fixing the ring reinforcement. After clamping, the gripping mechanism moves upwards and rotates to the top of the vertical reinforcement, fitting multiple vertical reinforcements inside the ring reinforcement. At this point, the gripping mechanism drives the ring reinforcement downwards to the appropriate binding position, where it is bound using the binding assembly. After binding, the movable carriage at the front moves forward, separating the gripping mechanism from the ring reinforcement. Repeating the above operation facilitates continuous gripping of the ring reinforcement. This method enables rapid binding of the reinforcing bars of viaduct piers, saving time and labor, improving binding efficiency, reducing labor costs, enhancing the safety of binding the reinforcing bars of viaduct piers, and facilitating construction.

[0021] 2. After the first servo motor pushes the slider at the rear end to move the binding assembly to the appropriate binding position, the piston rod of the second cylinder retracts, driving the movable block, push block and the main body of the rebar binding machine to move synchronously. After the push block slides inward along the slide groove to the appropriate position, the main body of the rebar binding machine binds the friction contact points of the vertical bars and the ring bars. Multiple rebar binding machine bodies operate at the same time, which improves the binding efficiency and facilitates the binding construction of the rebar of the viaduct piers.

[0022] 3. The use of mobile vehicles and supports makes it easy to move the grabbing mechanism and binding components to suitable positions, reducing the need for workers to work at heights, improving the safety of binding the steel bars of the viaduct piers, and facilitating rapid construction.

[0023] 4. The engagement between the locking block and the locking seat improves the stability of the ring reinforcement gripping, reduces the occurrence of falling after gripping, and also reduces the occurrence of large deformation due to uneven stress during the lifting process, thus protecting the integrity of the ring reinforcement.

[0024] 5. Through the meshing connection of the worm and worm wheel, the ring block is driven to rotate the clamping block and clamping seat, which facilitates the gripping of the ring ribs at different positions around the bracket. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figure 1-7 As shown, a reinforced concrete tying structure for a viaduct pier includes a pier cap 1, a pile foundation 2 fixed on the pier cap 1, a bridge body 3 fixed on the pile foundation 2, a reinforced concrete cage 4 cast inside the bridge body 3, and vertical bars 401 and ring bars 402 respectively provided inside the reinforced concrete cage 4. The vertical bars 401 and ring bars 402 are arranged in a linear and equally spaced structure with multiple vertical bars 401 and ring bars 402. Movable carts 5 are provided at both ends of the pile foundation 2. A support 6 is fixed on the top surface of the movable cart 5. A slider 7 is slidably connected to the support 6. A gripping mechanism 12 is provided on the slider 7 at the front end, and a binding assembly 13 is provided on the slider 7 at the rear end.

[0039] A rack 8 is fixedly mounted on the outer wall of the bracket 6, and a gear 9 is provided on the outer side of the slider 7. The inner end of the gear 9 is meshed with the outer side of the slider 7. Fixing blocks 10 are provided on both sides of the gear 9. One end of the fixing block 10 is connected and fixed to the outer wall of the bracket 6. A first servo motor 11 is mounted on the fixing block 10 through a mounting base. The output shaft of the first servo motor 11 is connected and fixed to the middle of the gear 9. The output shafts of the first servo motor 11 are all connected and fixed to the fixing blocks 10. The first servo motor 11 drives the gear 9 to rotate, and the gear 9 meshes with the rack 8, pushing the fixing block 10 to slide along the bracket 6 to a suitable working height, thereby moving the gripping mechanism 12 and the binding assembly 13 to a suitable working position.

[0040] The gripping mechanism 12 includes a ring block 1201, which is rotatably connected to a slider 7 located at the front end. A worm gear 1202 is sleeved on the lower outer wall of the ring block 1201. A worm 1203 is rotatably connected to the left end of the slider 7 located at the front end. The right end of the worm 1203 is meshed with the left end of the worm gear 1202. A second servo motor 1204 is mounted on the front wall of the slider 7 located at the front end through a mounting base. The output shaft of the second servo motor 1204 is coaxially connected to the front end of the worm 1203. The second servo motor 1204 drives the worm 1203 to rotate, and the worm 1203 meshes with the worm gear 1202 to make the ring block 1201 rotate along the slider 7 located at the front end to a suitable gripping position.

[0041] A connecting block 1205 is fixedly provided on the rear wall of the annular block 1201. A retaining seat 1206 is fixedly provided on the rear wall of the connecting block 1205. A first cylinder 1207 is installed on the top surface of the rear end of the connecting block 1205 through a mounting seat. A retaining block 1208 is slidably connected to the rear wall of the retaining seat 1206. The bottom surface of the piston rod of the first cylinder 1207 is connected and fixed to the top surface of the retaining block 1208. Multiple trapezoidal blocks 1210 are fixedly arranged in a uniform structure on the rear wall of the retaining seat 1206. The retaining blocks 1208 are all slidably connected to the trapezoidal blocks 1210. The top surface of the rear end of the retaining seat 1206 and the bottom surface of the retaining blocks 1208 are engaged with the annular rib 402 through the retaining groove 1209. The annular rib 402 is placed inside the retaining groove 1209 of the retaining seat 1206. The piston rod of the first cylinder 1207 pushes the retaining block 1208 to slide down along the trapezoidal block 1210 to clamp and fix the annular rib 402.

[0042] The working principle of the present invention is as follows: First, the upright rib 401 is welded and fixed to the pile foundation 2 by external welding equipment. Then, the support 6 is moved to a suitable use position by the mobile trolley 5. The first servo motor 11 drives the gear 9 to rotate. The gear 9 meshes with the rack 8 and pushes the fixing block 10 to slide along the support 6 to a suitable use height, thereby driving the gripping mechanism 12 and the binding assembly 13 to move to a suitable use position.

[0043] After adjusting the gripping mechanism 12 to a suitable position for gripping the outer ring rib 402, the second servo motor 1204 drives the worm gear 1203 to rotate. The worm gear 1203 meshes with the worm wheel 1202, causing the ring block 1201 to rotate along the slider 7 at the front end. This rotates the connecting block 1205 to a suitable gripping position, placing the ring rib 402 inside the slot 1209 of the card holder 1206. The piston rod of the first cylinder 1207 pushes the card block 1208 along the trapezoidal block 1210 towards... The gripping mechanism 12 slides down to clamp and fix the ring rib 402. After clamping, the gripping mechanism 12 moves upward and rotates to the upper end of the vertical rib 401, and puts multiple vertical ribs 401 inside the ring rib 402. At this time, the gripping mechanism 12 drives the ring rib 402 to move downward to a suitable binding position, and then binds it through the binding assembly 13. After binding, the movable carriage 5 located at the front end moves forward to separate the gripping mechanism 12 from the ring rib 402. Repeating the above operation facilitates the continuous gripping operation of the ring rib 402.

[0044] Example 2

[0045] like Figure 8 and Figure 9As shown, based on Embodiment 1, the binding assembly 13 includes a frame 1301. The top surface of the frame 1301 has multiple evenly arranged grooves 1302. Push blocks 1303 are slidably connected inside the grooves 1302. A rebar binding machine body 1304 is mounted on the top surface of the push blocks 1303 via a mounting base. A movable block 1305 is fixed to the outer end of the bottom surface of the push blocks 1303. A second cylinder 1306 is mounted on the outer wall of the movable block 1305 via a mounting base. The piston rod of cylinder 06 extends through the movable block 1305 to the inner end. The piston rod of the second cylinder 1306 is slidably connected to the movable block 1305. The inner wall of the piston rod of the second cylinder 1306 is connected and fixed to the outer wall of the frame 1301. After the piston rod of the second cylinder 1306 retracts, the push block 1303 slides along the slide groove 1302 to the inner end to the appropriate use position. Then, the body 1304 of the rebar binding machine binds the friction contact points of the vertical rebar 401 and the ring rebar 402.

[0046] During the binding process, the binding assembly 13 is moved to a suitable binding position by pushing the slider 7 at the rear end through the first servo motor 11. When the piston rod of the second cylinder 1306 retracts, it drives the movable block 1305, the push block 1303 and the rebar binding machine body 1304 to move synchronously. After the push block 1303 slides inward along the slide groove 1302 to a suitable position, the rebar binding machine body 1304 binds the friction contact points of the vertical bars 401 and the ring bars 402. Multiple rebar binding machine bodies 1304 operate simultaneously, which improves the binding efficiency and facilitates the binding construction of the rebar of the viaduct piers.
