Technical Field
[0001] This utility model relates to the field of concrete construction technology, and in particular to a grouting device and a wet spraying vehicle. Background Technology
[0002] In tunnel construction, the initial support after tunnel excavation is generally provided by a concrete spraying truck using hydraulic pressure to transport pre-mixed concrete through the spraying device pipeline connected to the boom to the spraying gun of the spraying device. Compressed air and accelerator are introduced into the spraying gun nozzle to spray the concrete at high speed onto the pre-received surface. After rapid setting and hardening, a concrete support layer is formed on the sprayed surface.
[0003] For example, a concrete wet spraying unit disclosed in CN214145521U includes a body system, a functional system, a pumping system, and a spraying system. The body system includes a chassis and an integral frame. The integral frame and chassis enclose a space for accommodating the functional system. The pumping system and the spraying system are connected to the body system. The pumping system is equipped with a pumping device and a grouting device. The grouting device receives concrete, and the pumping device pumps the concrete from the grouting device to the spraying system. Then, the concrete is sprayed through the spraying system, ultimately forming the concrete support layer formed on the sprayed surface.
[0004] Although the pumping system can provide storage for concrete by setting up a grouting device to facilitate the pumping of concrete, some concrete will remain inside the grouting device after construction is completed. This residue is difficult to clean and will solidify inside the grouting device. At that time, it will be necessary to remove the solidified concrete by inserting a cutting, which will cause inconvenience to the cleaning of the concrete. Utility Model Content

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0036] The grouting device of this utility model embodiment, by providing a grout outlet 12 for concrete discharge, can facilitate the discharge of concrete inside the grouting device, thereby avoiding the setting of concrete inside the grouting device and solving the technical problem of inconvenient cleaning of concrete inside the grouting device in the prior art.
[0037] This utility model provides a slurry feeding device, including a slurry feeding frame 10, a filter screen 20, a vibration unit 30, a sealing door 40, and a support unit 50. The top of the slurry feeding frame 10 is provided with a slurry inlet 11, and the bottom of the slurry feeding frame 10 is provided with a slurry outlet 12. The filter screen 20 is hinged to the top of the slurry feeding frame 10 and can cover the slurry inlet 11 by rotating around the slurry feeding frame 10. The vibration unit 30 is installed on the filter screen 20 and is used to drive the filter screen 20 to vibrate. The sealing door 40 is hinged to the bottom of the slurry feeding frame 10 and can seal the slurry outlet 12 by rotating around the slurry feeding frame 10. The support unit 50 is fixed to the bottom of the slurry feeding frame 10 and is used to support the sealing door 40 by abutting against it.
[0038] Specifically, the grouting device comprises a grouting frame 10, a filter screen 20, and a vibration unit 30. The grouting frame 10 has a grout inlet 11 at its top. The filter screen 20 is hinged to the top of the grouting frame 10, and the vibration unit 30 is mounted on the filter screen 20. Before concrete filling, the filter screen 20 rotates to cover the grout inlet 11. The vibration unit 30 is activated and drives the filter screen 20 to vibrate. During concrete filling, the concrete entering the grouting frame 10 enters the filter screen 20. The vibration unit 30 drives the filter screen 20 to vibrate, causing the concrete to pass through the filter screen 20 and enter the grouting frame 10, thus delivering grout into the grouting device. The grouting device also includes a sealing door 40 and... The support unit 50 has a grout outlet 12 at the bottom of the grout inlet frame 10. During concrete pumping, the sealing gate 40 seals the grout outlet 12 by rotating. The support unit 50 provides support for the sealing gate 40 sealing the grout outlet 12, preventing concrete from seeping out of the grout outlet 12. After the concrete construction is completed, the grout outlet 12 can be opened by rotating the sealing gate 40, allowing the remaining concrete inside the grout inlet frame 10 to pass out through the grout outlet 12, thereby preventing the concrete from solidifying inside the grout inlet frame 10 and facilitating concrete cleaning. By setting this grout inlet device, the wet spraying truck can facilitate both concrete pumping and concrete cleaning.
[0039] In this embodiment, after the concrete construction is completed, the slurry filter screen 20 can be opened first, and then the slurry inlet frame 10 can be rinsed with clean water. After rinsing the slurry inlet frame 10, the sealing door 40 can be opened to allow the sewage to flow out from the slurry outlet 12, thus achieving the rinsing of the remaining concrete inside the slurry inlet frame 10.
[0040] Understandably, the grouting frame 10 is any frame structure with a grouting inlet 11 at the bottom for concrete grouting and a grouting outlet 12 at the bottom for concrete grouting discharge.
[0041] In this embodiment, the size of the filter holes of the filter screen 20 can be adjusted adaptively according to the size of the solid particles in the concrete.
[0042] In this embodiment, to reduce the vibration amplitude of the filter screen 20, locking blocks 111 are provided on both sides of the slurry inlet 11. The locking blocks 111 are used to lock the filter screen 20 covering the slurry inlet 11. Specifically, by locking the filter screen 20, the locking blocks 111 can limit the position of the filter screen 20 covering the slurry inlet 11, thereby reducing the vibration amplitude of the filter screen 20 and providing support for the filter screen 20 to prevent deformation.
[0043] In some embodiments, the locking block 111 is provided with a limiting cavity 1111 and a bayonet 1112, the bayonet 1112 being connected to the limiting cavity 1111. Limiting rods 21 are provided on both sides of the filter screen 20, and the limiting rods 21 can enter the limiting cavity 1111 via the bayonet 1112 through the rotation of the filter screen 20. Specifically, by rotating the filter screen 20, the limiting rods 21 enter the limiting cavity 1111 via the bayonet 1112, thus achieving engagement with the locking block 111. This limits the vibration amplitude of the filter screen 20 without significantly hindering its rotation, facilitating the opening and closing of the filter screen 20.
[0044] In this embodiment, a handle 22 is provided on the filter screen 20 to facilitate its rotation. Specifically, the handle 22 can be gripped to facilitate the opening and closing of the pulp inlet 11.
[0045] In this embodiment, to facilitate grout injection, the grout injection device further includes two flared plates 60. The two flared plates 60 are fixed to the grout injection frame 10 and are respectively located on both sides of the grout injection port 11. The top of the flared plates 60 extends away from the grout injection port 11. Specifically, by being located on both sides of the grout injection port 11 and extending outward from the grout injection port 11, the flared plates 60 can effectively expand the grout injection port 11, facilitating grout injection into the grout injection port 11, while also blocking concrete and preventing concrete from overflowing from the grout injection port 11.
[0046] In some embodiments, the sealing door 40 includes a sealing portion 41, a hinge portion 42, and a gripping portion 43. The hinge portion 42 and the gripping portion 43 are located on opposite sides of the hinge portion 42. The hinge portion 42 is hinged to the slurry inlet frame 10. The sealing portion 41 can seal the slurry outlet 12 by rotating the hinge portion 42, and the gripping portion 43 provides a gripping function. Specifically, the hinge portion 42 enables the sealing plate to be hinged to the slurry inlet frame 10, and the gripping portion 43 provides a gripping function for the rotation of the sealing door 40, facilitating the opening and closing of the sealing door 40.
[0047] In some embodiments, the support unit 50 includes two support frames 51, which are respectively located on one side of the grout outlet 12. Each support frame 51 is provided with a support portion extending toward the grout inlet 11. The support portion is used to support the sealing portion 41 that seals the grout outlet 12. Specifically, the two support frames 51 can provide support for the sealing gate 40 on both sides of the grout outlet 12 through the support portion, thereby ensuring stable support for the sealing gate 40 and preventing the sealing gate 40 from deforming under the pressure of concrete.
[0048] In some embodiments, the sealing portion 41 is provided with an elastic support block 411, and the support unit 50 is used to support the sealing portion 41 that seals the grout outlet 12 through the support block. Specifically, the elastic support block 411 can provide elastic support for the sealing portion 41, so that the sealing portion 41 can better seal the grout outlet 12 under the support of the support portion, thereby preventing concrete from seeping out of the grout outlet 12.
[0049] In this embodiment, the elastic support block 411 is a rubber block.
[0050] In some embodiments, the thickness of the support block gradually decreases along the rotation direction when the sealing gate 40 seals the slurry outlet 12. Specifically, this arrangement of the support block allows the sealing gate 40 to fit more closely to the slurry outlet 12 as it rotates in the sealing direction. While ensuring the sealing performance of the sealing gate 40, it can also lock the sealing gate 40 to prevent it from rotating during the sealing process.
[0051] In some embodiments, the slurry feeding device further includes a clamp and a bend 80. The clamp is fixed to the slurry feeding frame 10, one end of the bend 80 is fixed to the slurry feeding frame 10, and the other end of the bend 80 is fixed by the clamp. The bend 80 can be connected to the slurry delivery pipe of the wet spraying vehicle.
[0052] An embodiment of this utility model also provides a wet spraying truck, including the aforementioned grout inlet device. Specifically, by providing the grout inlet device, the wet spraying truck can facilitate concrete pumping while also making concrete cleaning easier.
[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
