Description

Technical Field

[0001] The utility model relates to the technical field of bridge reinforcement, in particular to a road bridge construction device for reinforcing bridge cracks. Background Art

[0002] With the rapid development of the transportation industry, the safety and durability of roads and bridges, as vital infrastructure connecting cities and regions, are becoming increasingly important. However, over long periods of service, bridge structures often develop cracks of varying degrees due to environmental factors (such as temperature fluctuations, humidity fluctuations, and chemical erosion), loads (such as vehicle loads and wind loads), and material aging. If these cracks are not promptly addressed, they will seriously threaten the overall stability and safety of the bridge. Currently, crack injection filling with E-44 epoxy resin is a common and effective method for strengthening and repairing bridge cracks. Due to its excellent adhesion, corrosion resistance, and mechanical strength, E-44 epoxy resin can effectively fill cracks, enhance the integrity of bridge structures, and improve the load-bearing capacity and durability of bridges. In actual construction, E-44 epoxy resin is typically injected into cracks using a specific injection device to achieve reinforcement.

[0003] However, the existing bridge crack injection reinforcement device still has some shortcomings in practical application, especially in terms of the sealing between the connecting base and the crack injection tube. The existing injection mechanism often lacks an effective sealing design at the connecting base, resulting in the E-44 epoxy resin injected into the crack easily leaking or dripping from the port of the connecting base when replacing the syringe or performing other operations. This not only causes waste of E-44 epoxy resin materials and increases construction costs, but may also cause pollution to the surrounding environment. More importantly, it reduces the effect of crack reinforcement and may even cause reinforcement failure due to the loss of epoxy resin, posing a potential threat to the safety performance of the bridge.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0029] Reference Figures 1 to 5 , is the first embodiment of the utility model, which provides a road bridge construction device for strengthening bridge cracks. The road bridge construction device for strengthening bridge cracks includes a connecting assembly 100, including a positioning plate 101, a guide pipe 102 and a connecting seat 103. The guide pipe 102 is fixed to one side of the positioning plate 101, and the connecting seat 103 is fixed to the other side of the positioning plate 101.

[0030] Before injecting E-44 epoxy resin into the crack of the bridge, the surface of the bridge crack will be sealed with sealant to prevent the E-44 epoxy resin injected later from flowing out of the bridge. At this time, the positioning plate 101 can be fixed to one side of the bridge crack with the sealant, and the guide tube 102 can be inserted into the bridge crack. The connecting seat 103 is used for connecting an external injection device to facilitate the injection of E-44 epoxy resin into the bridge crack.

[0031] The sealing assembly 200 is arranged in the connecting seat 103, and includes a sealing plate 201a that slides in the connecting seat 103, a sealing strip 201b is fixed to the end of the sealing plate 201a, a sealing groove 201c is fixed to the other end of the sealing plate 201a, an extrusion block 201d is fixed to one side of the sealing plate 201a, and a first spring 201e is fixedly connected to the inner wall of the extrusion block 201d.

[0032] The first spring 201e is in a compressed state. Through the return elastic force of the first spring 201e, the two extrusion blocks 201d can drive the two sealing plates 201a to move closer to each other, so that the sealing strip 201b and the sealing groove 201c contact each other. Through the mutual cooperation between the sealing strip 201b and the sealing groove 201c, the E-44 epoxy resin in the connecting seat 103 can be prevented from leaking.

[0033] Specifically, the sealing assembly 200 further includes a detection member 202 , which is disposed in the connecting seat 103 and includes a detection block 202 a that slides in the connecting seat 103 , and a slide plate 202 b is fixedly connected to one side of the detection block 202 a .

[0034] The detection block 202a is used to detect the pressure of the E-44 epoxy resin in the connecting seat 103. When the bridge crack is not filled, the extrusion force of the E-44 epoxy resin on the detection block 202a is small. When the bridge crack is filled, the extrusion force of the E-44 epoxy resin on the detection block 202a becomes larger. At this time, the detection block 202a can push the slide 202b to move.

[0035] Preferably, a second spring 202c is fixed to the inner wall of the slide plate 202b, and a clamping plate 202d is fixed inside the slide plate 202b.

[0036] Preferably, a rotating shaft 202e is rotatably connected inside the connecting seat 103, and a positioning rod 202f is rotatably connected to the surface of the rotating shaft 202e.

[0037] Preferably, a third spring 202g is fixedly connected to one side of the positioning rod 202f, and a clamping slot 202d-1 is provided on one side of the clamping plate 202d.

[0038] The setting of the rotating shaft 202e can make the positioning rod 202f rotate, and the third spring 202g is in a compressed state, used to squeeze the positioning rod 202f, and the second spring 202c is in a compressed state, used to support the slide plate 202b. The positioning rod 202f is inserted into the card slot 202d-1, thereby positioning the card plate 202d, so that the card plate 202d positions the position of the slide plate 202b. Example

[0039] Reference Figures 1 to 5 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment:

[0040] Preferably, the sealing assembly 200 further includes an extrusion member 203 disposed on one side of the detection member 202, including a push block 203a fixed to one side of the slide plate 202b, and an arc surface 203a-1 is formed on one side of the push block 203a.

[0041] Preferably, a push plate 203b is provided on one side of the slide plate 202b, and the push plate 203b slides in the connecting seat 103. An inclined surface 203b-1 is provided on one side of the push plate 203b.

[0042] When the slide plate 202b is pushed by the detection block 202a, the slide plate 202b can drive the push block 203a to move, so that the push block 203a is used to squeeze the inclined surface 203b-1 at the end of the push plate 203b through the arc surface 203a-1, thereby pushing the push plate 203b to move.

[0043] Specifically, a fourth spring 203c is provided in the push plate 203b, and an extrusion sleeve 203d is slidably connected to the surface of the push plate 203b.

[0044] Specifically, an extrusion groove 201a-1 is formed on one side of the sealing plate 201a.

[0045] The fourth spring 203c is in a compressed state, and the push plate 203b slides in the extrusion sleeve 203d, and a limiting mechanism is provided between the push plate 203b and the extrusion sleeve 203d, so that the push plate 203b will not slide out of the extrusion sleeve 203d. When the push plate 203b is squeezed, the push plate 203b can further compress the fourth spring 203c, so that the fourth spring 203c pushes the extrusion sleeve 203d. At this time, the extrusion sleeve 203d can squeeze the sealing plate 201a. When the two sealing plates 201a approach each other, the extrusion groove 201a-1 will move to the end of the extrusion sleeve 203d, so that the extrusion sleeve 203d squeezes the extrusion groove 201a-1, thereby enhancing the extrusion force between the two sealing plates 201a, so that the sealing strip 201b and the sealing card groove 201c are more tightly combined, thereby improving the sealing effect of the connecting seat 103.

[0046] Preferably, the connecting assembly 100 further includes an injection head 104 inserted into the connecting seat 103 , one side of the injection head 104 is connected to the syringe 105 , and a push rod 106 is provided in the syringe 105 .

[0047] A piston is provided at the end of the push rod 106, which is used to push the E-44 epoxy resin in the syringe 105 toward the injection head 104, so that the E-44 epoxy resin is injected into the connecting seat 103 through the injection head 104. The injection head 104, syringe 105 and push rod 106 are existing technologies and will not be described in detail here.

[0048] During use, when it is necessary to reinforce the cracks in the bridge, first, use the sealant to seal the surface of the crack in the bridge to prevent the E-44 epoxy resin injected later from flowing out of the bridge. At this time, the positioning plate 101 can be fixed to one side of the crack in the bridge through the sealant, and the guide tube 102 is inserted into the crack in the bridge. At this time, the syringe 105 is filled with E-44 epoxy resin, and the injection head 104 is inserted into the connecting seat 103. At this time, the injection head 104 will squeeze the two extrusion blocks 201d, so that the two extrusion blocks 201d are separated from each other, thereby making the extrusion blocks 2 01d drives the two sealing plates 201a away from each other, so that E-44 epoxy resin can be injected into the crack of the bridge. When replacing the syringe or performing other operations, the injection head 104 will move out of the connecting seat 103. Through the reset elastic force of the first spring 201e, the two extrusion blocks 201d can drive the two sealing plates 201a to move closer to each other, so that the sealing strip 201b and the sealing card groove 201c contact each other. The mutual cooperation between the sealing strip 201b and the sealing card groove 201c can prevent the E-44 epoxy resin in the connecting seat 103 from leaking.

[0049] When the cracks in the bridge are filled with E-44 epoxy resin, the squeezing force of the E-44 epoxy resin on the detection block 202a becomes greater. At this time, the detection block 202a can push the slide plate 202b to move, and the slide plate 202b can drive the push block 203a to move, so that the push block 203a is used to squeeze the inclined surface 203b-1 at the end of the push plate 203b through the arc surface 203a-1, thereby pushing the push plate 203b to move. The push plate 203b can further compress the fourth spring 203c, so that the fourth spring 203c is pressed against the push plate 203b. The four springs 203c push the extrusion sleeve 203d, and at this time the extrusion sleeve 203d can squeeze the sealing plate 201a. When the two sealing plates 201a approach each other, the extrusion groove 201a-1 will move to the end of the extrusion sleeve 203d, so that the extrusion sleeve 203d squeezes the extrusion groove 201a-1, thereby enhancing the extrusion force between the two sealing plates 201a, so that the sealing strip 201b and the sealing card groove 201c are more tightly combined, thereby improving the sealing effect of the connecting seat 103.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
