Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment, and in particular to a grouting device for tunnel lining arch with formwork. Background Technology

[0002] Tunnel arch grouting with formwork is a commonly used technique in tunnel construction. Its core principle lies in reinforcing and supporting the tunnel arch by setting up a formwork at the top of the arch and then injecting grout within it. This technique not only effectively improves the safety of tunnel construction but also ensures the stability of the tunnel structure.

[0003] In the process of grouting with formwork at the tunnel arch, radial grouting pipes need to be pre-embedded on the trolley. Grouting should begin immediately through these pipes within two hours of the completion of the secondary lining concrete construction. Currently, grouting and slurry preparation machines are commonly used, integrating slurry preparation, storage, and grouting. These machines include a mixing tank for slurry preparation and a storage tank for storing the slurry. The tanks are equipped with a stirring mechanism to rapidly mix the raw materials during preparation and to prevent sedimentation, segregation, and initial setting of the slurry during storage, maintaining its uniformity and workability. However, in this equipment, the mixing tank and storage tank share a single stirring shaft, resulting in the same rotation speed in both. Setting the speed too high leads to a higher stirring speed in the storage tank, causing air to be introduced into the prepared slurry, generating bubbles. Simultaneously, the heat generated by high-speed stirring accelerates the hydration reaction of the slurry, reducing its fluidity and affecting concrete performance. Conversely, a lower speed hinders rapid slurry preparation, impacting work efficiency. Utility Model Content

The grouting mechanism 3 is located on the left side of the top surface of the vehicle body 1 and is connected to the mixing component 22 via a pipe. Raw materials are injected into the mixing component 22 of the pulping unit 2 for mixing, and the pulp is then stored in the storage component 21. During the mixing process, the first stirring component 23 rapidly stirs the pulp in the mixing tank 221, thereby rapidly pulping. During the storage process, the second stirring component 24 continuously stirs the pulp in the storage tank 211 to prevent sedimentation, segregation, and initial coagulation, and to maintain its uniformity and workability. The second stirring component 24 is connected to the first stirring component 23 through the speed changing component 25. The speed changing component 25 reduces the rotational speed of the first stirring component 23 and then transmits it to the second stirring component 24, so that the first stirring component 23 and the second stirring component 24 can stir at different speeds, thereby adapting to the speed requirements of pulping and storage.

[0033] The mixing assembly 22 includes a mixing tank 221, a feed hopper 223, and a discharge pipe 224. The mixing tank 221 is vertically arranged, and a feed inlet 222 is provided on the upper part of the right side wall of the mixing tank 221.

[0035] The storage assembly 21 includes a storage tank 211 and a discharge pipe 212; the storage tank 211 is vertically arranged; the discharge pipe 212 is located at the bottom of the storage tank 211 and connected to the grouting mechanism 3. The second stirring assembly 24 includes a second stirring shaft 241 and a second stirring blade 242; the second stirring shaft 241 is vertically arranged inside the storage tank 211, its top passing through the top surface of the storage tank 211, and is connected to the first stirring shaft 232 through the speed-changing assembly 25; the second stirring blade 242 is fixedly mounted on the second stirring shaft 241. When the prepared slurry enters the storage tank 211, the second stirring shaft 241 of the second stirring assembly 24 rotates under the action of the first stirring shaft 232 and the speed-changing assembly 25, driving the second stirring blade 242 to rotate, thus stirring the slurry in the storage tank 211.

[0036] It also includes a fixing rod 26 and a support base 27; the upper part of the fixing rod 26 is fixedly connected to the outer wall of the mixing tank 221, and the lower part is fixedly connected to the outer wall of the storage tank 211, and multiple fixing rods 26 are provided along the circumference of the mixing tank 221; the support base 27 is vertically arranged, its bottom is fixedly connected to the vehicle body 1, and its top is fixedly connected to the fixing rod 26.

[0037] In a further implementation, both the feed pipe 224 and the discharge pipe 212 are equipped with solenoid valves.

[0038] The transmission assembly 25 includes a mounting plate 251, a housing 252, a gear ring 253, a sun gear 254, planetary gears 255, a connecting shaft 256, a slewing bearing 257, a connecting plate 258, and a turntable 259. The mounting plate 251 is horizontally positioned, with its top surface fixedly connected to the bottom surface of the mixing tank 221. The housing 252 is located on the bottom surface of the mounting plate 251, is hollow inside, and has an open bottom surface. The gear ring 253 is horizontally positioned inside the housing 252, and has internal tooth grooves. The sun gear 254 is fixedly sleeved on the bottom of the first stirring shaft 232. The planetary gears 255... The planetary gears 255 are disposed within the gear ring 253 and are spaced apart along the circumference of the gear ring 253.

The turntable 259 is horizontally arranged, and its top surface is fixedly connected to the connecting plate 258. When the first stirring shaft 232 rotates, it drives the sun gear 254 to rotate, which in turn drives the planet gears 255 to rotate. This causes the planet gears 255 to revolve around the sun gear 254 within the gear ring 253, thereby driving the inner ring of the slewing bearing to rotate. The slewing bearing 257 then drives the connecting plate 258 and the turntable 259 to rotate. During the rotation of the turntable 259, the second stirring shaft 241 rotates, thus reducing the speed of the second stirring shaft 241 to be lower than that of the first stirring shaft 232. This allows the first stirring assembly 23 and the second stirring assembly 24 to stir at different speeds in the mixing tank 221 and the storage tank 211, respectively.

[0039] The number of teeth on the sun gear 254 is less than the number of teeth on the ring gear 253, thus achieving speed reduction.

[0041] It also includes an electrical control box 4; the electrical control box 4 is vertically mounted on the vehicle body 1 and is used to control various mechanisms.

[0042] The method of this utility model is as follows:

[0043] Raw materials enter the mixing tank 221 from the feed hopper 223 for pulping. The stirring motor 231 drives the first stirring shaft 232 to rotate, and the first stirring shaft 232 drives the first stirring blade 233 to rotate, stirring and mixing the raw materials in the mixing tank 221 to pulp. After pulping is completed, the pulp is injected into storage tank 211 through feed pipe 224. The second stirring shaft 241 of the second stirring assembly 24 rotates under the action of the first stirring shaft 232 and the speed change assembly 25, driving the second stirring blade 242 to rotate. When the first stirring shaft 232 rotates, it drives the sun gear 254 to rotate, and the sun gear 254 drives the planet gear 255 to rotate, so that the planet gear 255 revolves around the sun gear 254 in the gear ring 253, thereby driving the inner ring of the slewing bearing to rotate. The slewing bearing 257 drives the connecting plate 258 and the turntable 259 to rotate. During the rotation of the turntable 259, it drives the second stirring shaft 241 to rotate, reducing the speed of the second stirring shaft 241 and stirring the pulp in storage tank 211.

[0044] During grouting, the grouting mechanism 3 pressurizes the grout in the storage tank 211 from the discharge pipe 212 to the discharge pipe 33 to achieve grouting.
