Abstract
Description
Technical Field
[0001] The utility model relates to a road surface crack filling device. Background Art
[0002] Cement pavement is a more common type of road surface. Compared with traditional asphalt pavement, cement pavement is more prone to cracking. After cracking, vehicles will have a bumpy ride, and rainwater will flow in through the cracks and carry away the roadbed materials under the pavement, causing the lower part of the cement pavement to bulge and collapse, posing a major safety hazard.
[0003] Therefore, when cracks appear on the cement pavement, rapid grouting repair is required. The grouting repair uses concrete slurry, which is poured along the cracks. The repair work is completed after the concrete slurry dries.
[0004] In the prior art, grouting is done with a ladle, which scoops up concrete slurry and pours it along the cracks. This method of operation makes it easy for the concrete slurry to leak and requires frequent scooping. If the cracks are deep, the efficiency of the repair is extremely low.
[0005] Based on the above problems, we designed a pavement grouting device that is easier to operate and has higher grouting efficiency. Utility Model Content

[0027] In addition, in the description of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0028] In this utility model, unless otherwise specified or limited, the terms "disposed," "socketed," "connected," "through," and "inserted" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0029] See Figure 1 The pavement grouting device shown includes a base structure 1 that moves along the ground, a discharging unit 2 that cooperates with the base structure 1, and a storage unit 3 that is detachably matched with the discharging unit 2. The discharging unit 2 cooperates with the base structure 1 to discharge materials after being pressed down.
[0030] In the above technical solution, the base structure 1 can move along the ground and support the discharging unit 2 and the storage unit 3.
[0031] When the crack is reached, the discharging unit 2 is pressed down so that the concrete slurry in the discharging unit 2 is discharged directly into the crack through the base structure 1. After the crack is filled, the discharging unit 2 is released so that the discharging unit 2 rebounds and stops discharging.
[0032] See Figure 1 、 Figure 2 and Figure 3 As shown, the base structure 1 includes a box body 101, and four rollers 102 are symmetrically arranged on both sides of the box body 101. Under the support of the rollers 102, the bottom of the box body 101 is separated from the ground. A discharge nozzle 103 is inserted into the interior of the box body 101. The lower end of the discharge nozzle 103 passes through the box body 101 downward. The lower end of the discharge nozzle 103 is tapered to form a discharge end 104. The upper end of the discharge nozzle 103 is provided with a tapered sealing surface 10 5. A feed groove 106 is provided on the outer wall of the discharge nozzle 103, below the sealing surface 105. A conical cap 107 is detachably provided at the upper end of the discharge nozzle 103. The discharge nozzle 103 cooperates with the discharge unit 2. Two guide rods 108 are symmetrically provided on the top of the box body 101. A spring 109 is provided on the guide rod 108. A limiting cap 110 is provided at the upper end of the guide rod 108. The guide rod 108 cooperates with the discharge unit 2.
[0033] In the above technical solution, the elastic force of the spring needs to be sufficient so that it will not compress itself after carrying the fully loaded discharge unit 2 and storage unit 3.
[0034] In order to make the entire device more controllable, the weight of the discharge unit 2 and the storage unit 3 after full load needs to be around 20 kilograms.
[0035] After the concrete slurry in the storage unit 3 is emptied, the discharging unit 2 can be easily pressed down by manpower, making the operation of the device easier.
[0036] See Figure 6 As shown, in the above technical solution, by pressing down the discharge unit 2, the feed chute 106 enters into the interior of the discharge unit 2, and the concrete slurry inside the discharge unit 2 is guided downward into the ground crack through the discharge nozzle 103.
[0037] See Figure 2 and Figure 4 As shown, the discharge unit 2 includes a discharge pipe 201 and a pipe cover 202. The lower end of the discharge pipe 201 is provided with a pipe head 203. The discharge nozzle 103 is inserted downward from the inside of the discharge pipe 201 and is fixed to the box body 101 after insertion. An ear plate 204 is provided on the outer wall of the discharge pipe 201. The spring 109 acts on the lower part of the ear plate 204. The limiting cap 110 is limited to the upper part of the ear plate 204. Under the rebound action of the spring 109, the discharge pipe 201 moves upward, and the sealing surface 1 05 acts on the bottom surface of the discharge pipe 201 to form a seal therewith. When the discharge pipe 201 is pressed down, the feed trough 106 enters into the discharge pipe 201. At this time, the concrete slurry in the discharge pipe 201 is discharged from the discharge nozzle 103 after passing through the feed trough 106. An operating handle 205 is installed on the outer wall of the pipe cover 202. The pipe cover 202 is threadedly connected to the discharge pipe 201. A connecting pipe 206 is provided at the top axis of the pipe cover 202, which is connected to the storage unit 3 through the connecting pipe 206.
[0038] In the above technical solution, the openable discharge pipe 201 and the pipe cover 202 are combined to facilitate disassembly and cleaning after the repair and caulking are completed.
[0039] In the above technical solution, an operating handle 205 is used to facilitate applying downward pressure.
[0040] In the above technical solution, a detachable storage unit 3 is adopted, which facilitates the preparation of multiple storage units 3 to meet the need for repairing longer and deeper ground cracks.
[0041] See Figure 5 As shown, the storage unit 3 includes a storage bottle 31 , a valve 32 is provided at the bottom of the storage bottle 31 , and the valve 32 is threadedly connected to the connecting pipe 206 .
[0042] The capacity of a single storage bottle 31 is about 16 kg and can be easily opened by manpower. After the valve 32 is closed, leakage of concrete slurry can be avoided.
[0043] After the repair is completed, the valve and the storage bottle 31 need to be cleaned with clean water.
[0044] A first roller 33 is provided on the side of the storage bottle 31 near the top.
[0045] The design of the first roller 33 makes it easy to drag the storage bottle on the ground.
[0046] See Figure 2 、 Figure 6 and Figure 7As shown, a threaded portion is provided on the outer wall of the discharge nozzle 103, and a nut 133 is engaged with the threaded portion. A sealing ring 134 is provided on the upper end of the nut 133. When the nut 133 moves upward along the discharge nozzle to the extreme position, the sealing ring 134 is sealed to the bottom of the pipe head 203, and the discharge pipe 201 is restricted from downward movement at this time.
