Description

Technical Field

[0001] The utility model relates to a pouring device for sealing hinged joints of bridges, belonging to the technical field of building construction. Background Art

[0002] Cracks are one of the common diseases of bridges. The occurrence of cracks will reduce the bonding force between steel bars and concrete, reduce the bearing capacity of the bridge, and lead to the deterioration of the mechanical performance of the bridge structure, thus affecting the bearing capacity and service life of the bridge. Therefore, in order to restore the structural function of the bridge, there is a technology in the related art that uses epoxy resin AB glue to repair cracks.

[0003] Epoxy resin AB glue is another name for a two-liquid mixed hardening glue. One liquid is the main glue, and the other is the hardener. The two liquids can only harden when mixed. It does not need to rely on temperature to harden and mature. After the main glue and hardener are mixed, they will harden quickly. Therefore, they cannot be mixed in advance. Generally, they need to be mixed on site, and after mixing, the cracks in the bridge need to be quickly filled. Epoxy resin AB glue can be melted at high temperature for peeling.

[0005] In the above-mentioned related technologies, the main glue and hardener of the epoxy resin AB glue can be injected into the bridge cracks through different injection nozzle bodies respectively, so that the main glue and the hardener can melt in the bridge cracks. However, after the main glue and the hardener are filled into the bridge cracks respectively, it is difficult to ensure complete mixing, resulting in the possible insufficient hardening effect of the epoxy resin AB glue, which needs to be improved.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example: Please refer to Figures 1 to 6 The present embodiment provides a perfusion device for sealing hinged joints of bridges, including a glue perfusion component 1 and a hardener perfusion component 2. The glue perfusion component 1 includes a first distributor 11, and the first distributor 11 is provided with a first glue storage tank 12 storing glue. The first glue storage tank 12 is connected to the feeding end of the first distributor 11, and a first conveying pipe 13 is provided at the discharging end of the first distributor 11. A first voltage stabilizer 14 is also provided on the discharging end of the first distributor 11. Through the above-mentioned arrangement, when the first distributor 11 starts to work, the glue in the first glue storage tank 12 can be discharged from the first conveying pipe 13 to the outside.

[0027] The hardener pouring assembly 2 includes a second distributor 21, on which a second glue storage tank 22 storing hardener is provided. The second glue storage tank 22 is connected to the feed end of the second distributor 21, and a second delivery pipe 23 is provided at the discharge end of the second distributor 21. A second voltage stabilizer 24 is also provided at the discharge end of the second distributor 21. Through the above-mentioned arrangement, when the second distributor 21 starts working, the hardener in the second glue storage tank 22 can be discharged outward from the second delivery pipe 23.

[0028] The injection device also includes a mixed glue injection component 3, which includes a barrel 301, a first feed port 302 and a second feed port 303 are arranged on the top of the barrel 301, the pipe opening of the first delivery pipe 13 away from the first distributor 11 is connected to the first feed port 302, so that the first distributor 11 can deliver the glue into the barrel 301, and the pipe opening of the second delivery pipe 23 away from the second distributor 21 is connected to the second feed port 303, so that the second distributor 21 can deliver the hardener into the barrel 301. The bottom of the barrel 301 is arranged in a constricted structure to better gather materials. A discharge port 304 is provided at the bottom of the cylinder 301, and a glue injection needle 305 is provided on the discharge port 304. The glue injection needle 305 is extended to the outside of the cylinder 301, and the glue injection needle 305 can be inserted into the hinge joint of the bridge to perform the required glue injection work; a driving motor 306 is also provided on the top of the cylinder 301, and the electric spindle of the driving motor 306 is connected to a stirring shaft 307 extending into the cylinder 301, and the stirring shaft 307 is provided with stirring rods 308. The stirring rods 308 are staggered on the stirring shaft 307, so that the liquid in the cylinder 301 can be evenly stirred, and has the characteristic of a large stirring area.

[0029] Through the above-mentioned arrangement, when the glue injection work is carried out, the glue in the first glue storage tank 12 is injected into the cylinder 301 through the first delivery pipe 13 through the first distributor 11, and the hardener in the second glue storage tank 22 is injected into the cylinder 301 through the second delivery pipe 23 through the second distributor 21. Then, the drive motor 306 is started to start working, and the stirring shaft 307 starts to rotate, thereby driving the stirring rod 308 to rotate, so that the glue and the hardener in the cylinder 301 can be stirred, so that they are fully mixed to form the required epoxy resin AB glue. The formed epoxy resin AB glue can be injected into the hinge joint of the bridge from the discharge port 304 through the glue injection needle 305, so as to perform the required sealing work and achieve the required effect of repairing the bridge.

[0030] In order to ensure the quality of the epoxy resin AB glue formed in the cylinder 301, a first flow valve 309 for controlling the conduction state of the first feed port 302 is provided on the first feed port 302, a second flow valve 310 for controlling the conduction state of the second feed port 303 is provided on the second feed port 303, and a third flow valve 311 for controlling the conduction state of the discharge port 304 is provided on the discharge port 304. Through the above-mentioned settings, when in actual use, the staff can use the first flow valve 309 and the second flow valve 310 to open and adjust the flow of the glue and the hardener entering the cylinder 301, so as to ensure that the ratio of the glue and the hardener in the cylinder 301 tends to be stable, and the staff can use the third flow valve 311 to adjust the flow of the epoxy resin AB glue output from the cylinder 301 to ensure that the output epoxy resin AB glue is completely mixed glue.

[0031] To facilitate the subsequent stripping of the epoxy resin AB glue remaining in the cylinder 301, the cylinder 301 is made of heat-conducting metals commonly used in the prior art, such as copper, aluminum, etc. When the epoxy resin AB glue remaining in the cylinder 301 needs to be stripped, the cylinder 301 is heated. The cylinder 301 made of heat-conducting metal can be heated quickly, thereby softening the epoxy resin AB glue remaining in the cylinder 301 and reducing its viscosity, so that it can be discharged from the cylinder 301.

[0032] In order to facilitate the glue injection work, the injection device also includes a support assembly 4, which includes a support ring 41. The cylinder 301 is arranged to pass through the support ring 41 from the inner ring part of the support ring 41. The bottom of the support ring 41 is provided with a support foot 42 for standing. In this embodiment, the number of the support feet 42 is three, and the support feet 42 are distributed in a circular array at the bottom of the support ring 41 with the central axis of the support ring 41 as the array center. At least one clamping screw 43 is threadedly connected to the side wall of the support ring 41. The nail tip of the clamping screw 43 is inserted into the inner ring part of the support ring 41 and is clamped with the outer wall of the cylinder 301 to fix the cylinder 301 inside the support ring 41. The specific number of the support feet 42 and the clamping screw 43 can be determined according to actual conditions.

[0033] The working principle of the utility model is that when performing the glue injection work, the support ring 41 is placed on the hinge joint of the bridge to be repaired by using the support foot 42, and then the cylinder 301 is passed through the support ring 41 and fixed by using the clamping screw 43. Then, after adjusting the first flow valve 309 and the second flow valve 310 to a suitable opening, the glue in the first glue storage tank 12 is injected into the cylinder 301 through the first delivery pipe 13 through the first distributor 11, and the hardener in the second glue storage tank 22 is injected into the cylinder 301 through the second delivery pipe 23 through the second distributor 21, and then the driving motor 306 is started to work, and the glue and hardener in the cylinder 301 are stirred to be fully mixed to form the required epoxy resin AB glue, and then the third flow valve 311 is adjusted to a suitable opening so that the formed epoxy resin AB glue can be discharged from the glue injection needle 305 to perform the required glue injection work.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
