Description

Technical Field

[0001] The utility model belongs to the field of grouting technology, and in particular relates to a safe and efficient grouting reinforcement device. Background Art

[0002] Grouting can be categorized into ceramic grouting and construction grouting. Ceramic grouting involves injecting prepared slurry into ceramic production. Construction grouting involves injecting a solidifying slurry into cracks or pores in the rock foundation using appropriate methods, improving its physical and mechanical properties through displacement, filling, or extrusion.

[0003] Chinese patent publication number CN212614764U discloses an efficient grouting device for roadway surrounding rock reinforcement, comprising a first rotating rod, a storage tank, and a discharge pipe. A visual window is provided at one end of the storage tank, and legs are provided on both sides of the bottom end of the storage tank. A drive motor is installed on one side of the top of the storage tank, and a transmission rod is connected to one side of the drive motor. A second rotating rod is installed on one side of the interior of the storage tank via a rotating shaft, and one side of the second rotating rod extends to one side of the storage tank. A feed port is installed on the top of the storage tank on one side of the drive motor, and a first rotating rod is installed on one side of the interior of the feed port via a rotating shaft. The utility model rotates the first rotating rod by rotating the adjusting disk, causing the baffle to flip, which can quickly clear blocked slurry and prevent slurry blockage. This structure realizes the anti-blocking function of the device and helps to increase the service life of the device.

[0004] However, during grouting, slurry needs to be injected into the cracks or pores of the foundation. When the slurry is injected, there will be an outward reaction force that pushes the device outward, resulting in unstable grouting. At the same time, the distance between the cracks and pores during grouting is too small, and there is a lack of thrust on the slurry, which causes the slurry to be unable to reach the depths of the cracks and pores.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a safe and efficient grouting reinforcement device, which solves the problem proposed in the above-mentioned background technology that during grouting, slurry needs to be injected into foundation cracks or pores. When injecting slurry into the cracks or pores, there will be an outward reaction force pushing the device outward, resulting in unstable grouting. At the same time, during grouting, the spacing between cracks and pores is too small, and there is a lack of thrust on the slurry, which results in the slurry being unable to reach the depths of the cracks and pores.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A safe and efficient grouting reinforcement device comprises: a U-shaped frame, a connecting block fixedly connected to one side of the surface of the U-shaped frame, a driving component for squeezing slurry fixedly connected to the surface of the connecting block, and fixing plates provided on both sides of the U-shaped frame, and fixing components for improving grouting stability provided on the surfaces of the fixing plates.

[0009] Optionally, the drive assembly includes a drive motor fixedly connected to the surface of the connecting block, the output end of the drive motor is fixedly connected to a first bevel tooth, the surface of the first bevel tooth is meshingly connected to a second bevel tooth, the interior of the second bevel tooth is sleeved with a threaded barrel, one end of the threaded barrel is fixedly connected to a fixing ring, the interior of the fixing ring is sleeved with a bearing, the interior of the bearing is sleeved with a connecting seat, and the interior of the threaded barrel is threadedly connected to a threaded rod.

[0010] Optionally, the fixing assembly includes a short threaded cylinder arranged on the surface of the fixing plate, and the internal thread of the short threaded cylinder is connected to a threaded tapered rod.

[0011] Optionally, a grouting barrel is fixedly connected to the interior of the U-shaped frame, a pressing sheet is slidably connected to the interior of the grouting barrel, and a sliding groove is axially symmetrically provided on the inner wall of the grouting barrel, and the interior of the sliding groove is slidably connected to both sides of the pressing sheet.

[0012] Optionally, a through hole is opened in the middle of the surface of the U-shaped frame, the surface of the through hole is fixedly connected to one side of the connecting seat, and one end of the threaded rod is threaded through the threaded tube, the through hole and the interior of the grouting tube and is fixedly connected to the surface of the pressing sheet.

[0013] Optionally, an injection hole is provided at the top of the grouting cylinder, and a grouting pipe for adding slurry is provided on the surface of the injection hole.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] The screw threaded rod is connected to the inner wall of the screw threaded barrel and one end of the screw threaded barrel is fixed to the cracks and pores where grouting is required. At this time, the threaded cone rods on both sides of the U-shaped frame are rotated so that the threaded cone rods are nailed into the ground through the fixing plate, thereby fixing the U-shaped frame to avoid displacement due to the reaction thrust during grouting, thereby improving the gradual stability. When grouting starts, the driving motor can be connected to an external power supply to drive the first bevel gear and the second bevel gear to rotate, thereby driving the threaded barrel and the fixing ring to rotate on the surface of the connecting seat through the bearing. Since the threaded rod is threadedly connected to the inside of the threaded barrel and one end of the threaded rod is fixedly connected to the surface of the pressing piece, the sliding track of the pressing piece inside the grouting barrel is limited by the slide groove. As the threaded rod rotates, the pressing piece can be driven to push the slurry water inside the grouting barrel to move, thereby applying a thrust to the slurry water, facilitating the injection of the slurry water into the cracks and pores, thereby improving the grouting quality.

[0016] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

The surface of the fixing plate 4 is provided with a fixing component 5 for improving the grouting stability. During grouting, the device is moved to the grouting position, and one end of the grouting tube 6 is aligned with the cracks and pores that need grouting. At this time, the threaded tapered rods 52 on both sides of the U-shaped frame 1 are rotated so that the threaded tapered rods 52 are nailed into the ground through the fixing plate 4, thereby fixing the U-shaped frame 1, avoiding displacement of the U-shaped frame 1 due to the reaction thrust during grouting, thereby gradually improving the stability.

[0028] One aspect of the application of this embodiment is: when grouting begins, the drive motor 31 can be connected to an external power source so that it drives the first bevel gear 32 and the second bevel gear 33 to rotate, and then drives the threaded barrel 34 and the fixed ring 35 to rotate on the surface of the connecting seat 37 through the bearing 36. Since the threaded rod 38 is threadedly connected to the inside of the threaded barrel 34, and one end thereof is fixedly connected to the surface of the pressing plate 7, and the sliding trajectory of the pressing plate 7 inside the grouting barrel 6 is limited by the chute 8, as the threaded rod 38 rotates, the pressing plate 7 can be driven to push the slurry water to move inside the grouting barrel 6, thereby applying a thrust to the slurry water, making it easier to inject the slurry water into the crack pores and improve the grouting quality. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

[0029] like Figure 2 As shown, the interior of the U-shaped frame 1 of this embodiment is fixedly connected to a grouting tube 6, the interior of the grouting tube 6 is slidably connected to a pressing plate 7, and the inner wall of the grouting tube 6 is axially symmetrically provided with a slide groove 8, and the interior of the slide groove 8 is slidably connected to both sides of the pressing plate 7. The setting of the pressing plate 7 can slide on the inner wall of the grouting tube 6 and push the slurry outward to complete the grouting.

[0030] like Figure 2 As shown, an injection hole is provided at the top of the grouting tube 6 of this embodiment, and a grouting pipe 9 for adding slurry water is provided on the surface of the injection hole. The setting of the grouting pipe 9 can replenish slurry water into the interior of the grouting tube 6 in time through the grouting pipe 9, thereby improving the convenience of slurry water replenishment.

When grouting starts, the driving motor 31 can be connected to an external power supply to drive the first bevel gear 32 and the second bevel gear 33 to rotate, and then drive the threaded barrel 34 and the fixing ring 35 to rotate on the surface of the connecting seat 37 through the bearing 36. Since the threaded rod 38 is threadedly connected to the inside of the threaded barrel 34, and one end thereof is fixedly connected to the surface of the pressing plate 7, and the sliding trajectory of the pressing plate 7 inside the grouting barrel 6 is limited by the slide groove 8, as the threaded rod 38 rotates, the pressing plate 7 can be driven to push the slurry water to move inside the grouting barrel 6, thereby applying a thrust to the slurry water, facilitating the injection of the slurry water into the crack pores and improving the grouting quality.

[0033] Example 2:

[0034] In this embodiment, if Figure 4 As shown, the fixing assembly 5 includes a threaded short cylinder 51 provided on the surface of the fixing plate 4, and the internal thread of the threaded short cylinder 51 is connected to a threaded tapered rod 52. During grouting, the device is moved to the grouting position, and one end of the grouting cylinder 6 is aligned with the cracks and pores that need grouting.
