Description

Technical Field

[0001] This invention belongs to the field of box girder manufacturing technology, specifically a modular intelligent hydraulic manufacturing method for precast box girders. Background Technology

[0002] Reinforced concrete box girders are divided into precast box girders and cast-in-place box girders. Box girders precast on an independent site can be erected after the substructure is completed using a bridge erecting machine, which can accelerate the project progress and save construction time. Cast-in-place box girders are mostly used for large continuous bridges. They are commonly classified by material into two main types: prestressed reinforced concrete box girders and steel box girders. Prestressed reinforced concrete box girders are constructed on-site and, in addition to longitudinal prestressing, some also have transverse prestressing. Steel box girders are generally prefabricated in a factory and then transported to the site for installation. They are suitable for the production of standardized components, with short construction time and controllable quality.

[0003] Regarding the formwork, in the existing technology, when demolding and assembling precast box girders, the side beams are generally controlled by a single hydraulic formwork. This requires multiple workers to stand in different positions to monitor the status of the side formwork and send instructions to the control personnel through communication devices. This makes the disassembly and assembly of box girder formwork relatively time-consuming and labor-intensive, increases the labor intensity of workers, and reduces the efficiency of the use of precast hydraulic formwork for box girders.

[0012] Preferably, each of the meshing components consists of a tooth and a spur gear meshing with it. The other end of the tooth plate is fixedly connected to the plate body of the bent plate frame, and a screw is fixedly connected through the spur gear. The screw is specifically composed of two sections of opposite threaded rods. Both ends of the screw are movably fitted with ear plates, and the plates of the two ear plates are fixedly connected to the outer wall of the template plate.

A single electric cylinder drives the template assembly and vibration, and the linkage shrinkage structure and meshing components enable multi-process collaboration. The hydraulic walking template supports reuse, reducing material waste. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0031] like Figures 1 to 8 As shown, the present invention provides a modular intelligent hydraulic manufacturing method for precast box girders, including a preparation frame 1. Two sets of templates 101 are symmetrically arranged on the top of the preparation frame 1. The two sets of templates 101 are fixedly connected to the top plate of the preparation frame 1 and are also slidably connected. A thickened plate 102 is fixedly connected to the inner wall of one set of templates 101 fixed on the preparation frame 1, while a forming metal plate 103 is fixedly connected to the inner wall of the other set of templates 101. A hydraulic forming part 2 is provided between the outer walls of the preparation frame 1 and the other set of templates 101.

[0032] The hydraulic molding unit 2 includes a conical slide plate 203. Both ends of the outer wall of the conical slide plate 203 are slidably connected to bent plate frames 204 for pushing a corresponding set of templates 101. A shrinkage structure is provided between the conical slide plate 203 and one end plate of the two bent plate frames 204, while a meshing vibration structure is provided between the other end plate of the two bent plate frames 204 and the corresponding set of templates 101.

[0033] The above scheme is adopted: the bent plate frame 204 at both ends slides according to the shape of the conical slide plate 203, so that the two bent plate frames 204 directly drive the corresponding two templates 101 and thickened plate 102 to move through the T-shaped groove plate 213, so that they are attached and assembled together with the other two templates 101, thickened plate 102 and forming metal plate 103 fixed on the preparation frame 1, forming a space that is sealed on all sides and has a T-shaped interior; in the subsequent process, when part of the hinge plate 219 is passively tilted, it will simultaneously drive the tilting ball rod 224 to tilt, thereby suddenly pressing the plate of the contact plate 225, so that it is simultaneously pressed and struck by the T rod 227 and the spring 228. When the T rod 227 is suddenly subjected to force, it will immediately strike the outer wall plate of the template 101, causing external force vibration to the cement slurry in its inner wall, directly increasing the density between the cement slurry.

[0034] The hydraulic molding unit 2 also includes a placement cylinder 201 fixedly connected to the bottom outer wall of the preparation frame 1. An electric cylinder 202 is fixedly connected to the bottom outer wall of the placement cylinder 201. The movable end of the electric cylinder 202 is slidably connected to the bottom cylinder of the placement cylinder 201. The movable end of the electric cylinder 202 is also fixedly connected to the bottom outer wall of the conical slide plate 203. The plates of the two bending plate frames 204 are also slidably connected to both ends of the placement cylinder 201. Support plates 205 are fixedly connected to the plates of the two bending plate frames 204. Elastic telescopic members 206 are fixedly connected to both sides of the plates of the two support plates 205. One end of the rod of the two sets of elastic telescopic members 206 is fixedly connected to the outer walls of both ends of the preparation frame 1 respectively.

[0035] The above method is adopted: after the bundled steel bars are placed on the preparation frame 1, the electric cylinder 202 installed on the placing cylinder 201 is activated, causing its movable end to retract and drive the conical slide 203 to move downward together, as shown. Figure 3 As shown, the downward-moving conical slide plate 203 no longer continuously limits the bending plate frame 204 that is attached at both ends. At the same time, the two elastic telescopic members 206 installed on the support plate 205 will also elastically contract, so that the bending plate frame 204 at both ends can slide according to the shape of the conical slide plate 203. Thus, the two bending plate frames 204 directly drive the corresponding two templates 101 and thickened plates 102 to move horizontally through the T-shaped groove plate 213, so that they are attached and assembled together with the other two templates 101, thickened plates 102 and forming metal plates 103 fixed on the preparation frame 1, forming a space that is sealed on all sides and has a T-shaped interior. At that time, cement slurry can be poured into it. The cement slurry needs to be poured in batches.

[0036] The shrinking structure includes multiple arc-shaped retaining plates 207 that are slidably connected to the outer wall of the top of the conical slide plate 203. A stepped conical component 208 is rotatably connected to the inner wall of each arc-shaped retaining plate 207. A vertical rod 209 is slidably connected through the center of the stepped conical component 208. The outer wall of the vertical rod 209 near the bottom is threaded. A T-shaped slider 210 is fixedly connected to the outer wall of the bottom end of each arc-shaped retaining plate 207. A T-shaped groove 211 is provided on the top plate of the conical slide plate 203, which can slide and engage with each T-shaped slider 210. A spring 212 is fixedly connected between the outer wall of one end of each T-shaped slider 210 and the inner wall of one end of the T-shaped groove 211.

[0037] Using the above scheme: Each time a portion of mud is fed, the electric cylinder 202 will drive the conical slide plate 203, multiple arc-angle clamping plates 207, and a stepped conical component 208 to move downwards simultaneously. During this process, one end of the bent plate frame 204 will slide against the inner wall of the corresponding arc-angle clamping plate 207, and the stepped conical component 208 will passively move downwards guided by the vertical rod 209. Once the threaded portion of the stepped conical component 208 and the vertical rod 209 engages, the stepped conical component... When component 208 rotates downwards, the stepped shape on the stepped cone component 208 will cause multiple arc-angle clamping plates 207 to be elastically driven by spring 212. Through the contact and engagement between the T-shaped slider 210 and the T-shaped groove 211, they will passively move horizontally. The passive translation between the arc-angle clamping plates 207 will cause the opening to become smaller, which will cause the bent plate frame 204 attached to the arc-angle clamping plate 207 to move accordingly under the influence of the elastic telescopic component 206.

[0038] The meshing vibration structure includes a T-shaped groove plate 213 that slides onto the plate of the bending plate frame 204. One end of the T-shaped groove plate 213 is fixedly connected to the outer wall of the corresponding template 101. A spring 214 is fixedly connected between the outer wall of the template 101 and the other end of the plate of the bending plate frame 204. Meshing components 215 are provided on both ends of the plate of the bending plate frame 204 near the template 101. Each meshing component 215 consists of a tooth and a spur gear meshing with it. The other end of the tooth plate is fixedly connected to the plate of the bending plate frame 204, and a screw 216 is fixedly connected through the spur gear. Specifically, it consists of two oppositely threaded rods. Both ends of the screw 216 are movably fitted with ear plates 217. The plates of both ear plates 217 are fixedly connected to the outer wall of the template 101. Both ends of the screw 216 are threadedly connected with sleeve rods 218. One end of each sleeve rod 218 is fixedly connected with a hinge plate 219. A bent guide groove plate 220 is also slidably connected to the plates of the two hinge plates 219. One end of the bent guide groove plate 220 is fixedly connected to the corresponding outer wall of the template 101. Multiple arc-angle abutment plates 221 are fixedly connected in an array in the inner wall of the bent guide groove plate 220.

[0039] The above solution is adopted: such as Figure 6 As shown, the plate of the bending plate frame 204 will be limited and translated within the T-shaped groove plate 213, while simultaneously compressing the second spring 214, causing it to deform. The presence of the second spring 214 facilitates the overall force on the bending plate frame 204 and the T-shaped groove plate 213 to drive the template 101 to translate when the rod of the electric cylinder 202 retracts. Instantly, the translation of the bending plate frame 204 will drive the toothed plate in the meshing assembly 215 to translate in real time, thereby driving the spur gear to mesh and rotate. This will drive the screw 216 to rotate synchronously, causing the two sleeve rods 218 and the hinge plate 219 to perform horizontally guided translation in opposite directions under the limitation of the bending guide groove plate 220. The passive translation of the hinge plate 219 will cause it to resist and tilt when it comes into contact with the arc-angle abutment plate 221.

[0040] The hinge plate 219 can be intermittently and slidably connected to multiple arc-angle abutment plates 221. An L-shaped support plate 223 is fixedly connected to the hinge plate 219. A ball bearing spring 222 is movably connected between the L-shaped support plate 223 and the hinge plate 219. An inclined ball rod 224 is also fixedly connected to the hinge plate 219. A touch plate 225 is slidably connected to the other end of the inclined ball rod 224. A vertical plate 226 is fixedly connected to the bent guide groove plate 220. Multiple striking T-bars 227 are movably connected to the other end of the touch plate 225. Each striking T-bar 227 is slidably connected to the plate of the vertical plate 226. The other end of each striking T-bar 227 can be intermittently and slidably connected to the outer wall of the template 101. Multiple springs 228 are also fixedly connected between the touch plate 225 and the vertical plate 226.

[0041] Using the above solution: the tilted hinge plate 219 will be simultaneously subjected to pressure and compression on the ball bearing spring member 222 installed between the L-shaped support plate 223, causing it to deform. The ball bearing spring member 222 facilitates the subsequent repositioning of the unloaded hinge plate 219. Figure 8 As shown, the passive tilting of part of the hinge plate 219 will simultaneously cause the tilting rod 224 to tilt, thereby suddenly pressing the plate of the contact plate 225, causing it to simultaneously press and strike the T-rod 227 and the spring 228. When the T-rod 227 is suddenly subjected to force, it will immediately strike the outer wall plate of the template 101, causing external vibration to the cement slurry in its inner wall, directly increasing the density between the cement slurry particles. After the tilting rod 224 returns to its original position with the hinge plate 219, the presence of the spring 228 will cause the previously applied force to continuously fluctuate. This fluctuation will keep the T-rod 227 continuously striking the outer wall plate of the template 101 with different forces for 4-7 seconds, thus allowing it to feel different fluctuations, such as... Figure 2 As shown, as the stepped conical piece 208 moves down intermittently and passively, it indirectly causes the two sets of hinged plates 219 to move in opposite directions intermittently. This achieves the corresponding staged impact vibration as the cement is poured in stages. The above can realize the rapid assembly and disassembly of multiple templates 101 through a single power source, without the need for real-time manual monitoring, reducing manual work and also increasing the density of the cement slurry of the precast box girder in real time.

[0042] The working principle and usage process of this invention are as follows: After the bundled steel bars are placed on the preparation frame 1, the electric cylinder 202 installed on the placement cylinder 201 is activated, causing its movable end to contract and drive the conical slide plate 203 to move downwards. The downward-moving conical slide plate 203 no longer continuously limits the bending plate frame 204 that is attached at both ends. At the same time, the two elastic telescopic members 206 installed on the support plate 205 will also contract elastically, allowing the bending plate frame 204 at both ends to slide according to the shape of the conical slide plate 203. Thus, the two bending plate frames 204 directly drive the corresponding two templates 101 and thickened plates 102 to move horizontally through the T-shaped groove plate 213, so that they are attached and assembled together with the other two templates 101, thickened plates 102 and forming metal plates 103 fixed on the preparation frame 1. When a portion of mud is poured, the electric cylinder 202 will drive the conical slide plate 203, multiple arc-angle clamping plates 207 and a step. As the conical component 208 moves downwards synchronously, one end of the bent plate frame 204 slides against the inner wall of the corresponding arc-angle clamping plate 207 during this process. When the stepped conical component 208 is passively guided downwards on the vertical rod 209, once the threaded portions on the stepped conical component 208 and the vertical rod 209 engage, causing the stepped conical component 208 to rotate downwards, the phased shape of the stepped conical component 208 will cause multiple arc-angle clamping plates 207 to be subjected to spring forces. Driven by the elasticity of 212, passive horizontal movement is generated through the contact and engagement between the T-shaped slider 210 and the T-shaped groove 211. The passive translation between the arc corner plates 207 causes the opening to become smaller, which causes the bent plate frame 204 attached to the arc corner plate 207 to move under the influence of the elastic telescopic member 206. The plate of the bent plate frame 204 will be limited and translated within the T-shaped groove plate 213, while compressing the second spring 214 to deform it.

[0043] Instantly, the translation of the bending plate frame 204 will drive the toothed plate in the meshing assembly 215 to translate in real time, thereby driving the spur gear to mesh and rotate. This will drive the screw 216 to rotate synchronously, causing the two sleeve rods 218 and the hinge plate 219 to translate in opposite directions in a horizontal guiding manner under the limitation of the bending guide groove plate 220. The passive translation of the hinge plate 219 will cause it to resist and tilt when it comes into contact with the arc-angle abutment plate 221. At the same time, it will be squeezed by the ball shaft elastic member 222 installed between the L-shaped support plate 223, causing it to deform. The passive tilting of part of the hinge plate 219 will simultaneously drive the tilting ball shaft elastic member 222 to tilt. The lever 224 is tilted, thereby suddenly pressing the plate of the contact plate 225, causing it to be simultaneously pressed and struck by the T-lever 227 and the spring 228. When the T-lever 227 is suddenly subjected to force, it will immediately strike the outer wall plate of the template 101, causing external vibration to the cement slurry in its inner wall. After the tilted lever 224 returns to its original position with the hinge plate 219, the presence of the spring 228 will cause the previously applied force to continuously fluctuate. This fluctuation will keep the T-lever 227 continuously striking the outer wall plate of the template 101 with different forces between 4 and 7 seconds, so that it feels different fluctuations.

[0044] One point that needs to be added is that the top of the vertical rod 209 is fixedly connected to the bottom outer wall of the template 101. When no additional force is applied to the spring 214, the passive translation of the bending frame 204 in the first stage will not squeeze the spring 214, but will only directly drive the T-shaped groove plate 213 and the corresponding template 101 to move.
