[0002] Hydraulic grouting is an important technology in the construction of water conservancy projects. It is mainly used to strengthen foundations, prevent seepage and leaks, fill gaps or repair structures. Slurry (such as cement slurry, chemical slurry, etc.) is injected into rock and soil layers or structural gaps through drilling. The solidification, bonding or filling effect of the slurry is used to improve the physical and mechanical properties of the foundation or form an anti-seepage barrier.

[0003] The grouting equipment mainly consists of a slurry storage barrel, a grouting pump and a grouting pipeline. The slurry is mixed in the slurry storage barrel, pumped into the grouting pipeline by the grouting pump, and then transported to the hole for grouting.

[0004] In actual working conditions, if chemical slurry or quick-setting slurry is used, each barrel must be cleaned, that is, after each barrel of slurry is poured, the slurry storage barrel, grouting pump and pipeline must be cleaned. However, since the slurry storage barrel has stirring components, it is difficult and time-consuming to clean it, which leads to extended construction period and slow construction efficiency.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] like Figures 1-4 As shown, the present embodiment provides a grouting device for water conservancy project construction, including a machine base 1, a rotating table 2, a slurry mixing barrel 3, a bracket 4, a stirring shaft 5, a driving mechanism 6 and a lifting mechanism. The rotating table 2 is rotatably connected to the upper side of the machine base 1, and the slurry mixing barrel 3 is connected on both sides of the rotating table 2. The bracket 4 is connected on both sides of the rotating table 2, and the bracket 4 corresponds to the slurry mixing barrel 3. The bracket 4 is movably connected to the stirring shaft 5, and the stirring shaft 5 rotates along the axis. The stirring shaft 5 can slide vertically, and the stirring shaft 5 corresponds to the slurry mixing barrel 3. The driving mechanism 6 is connected to the rotating table 2, and the driving mechanism 6 drives the two stirring shafts 5 to move.

[0019] In the above embodiment, two slurry mixing barrels 3 are arranged on the rotating table 2, one is used for slurry mixing and slurry delivery, and the other is cleaned and kept in standby. After slurry mixing is carried out in one of the slurry mixing barrels 3, grouting operation is carried out. After the slurry in the slurry mixing barrel 3 is used up, the rotating table 2 rotates, and the clean standby slurry mixing barrel 3 takes over the work and performs slurry mixing operation, while the replaced slurry mixing barrel 3 is cleaned at the same time and kept in standby after cleaning, which greatly improves the grouting efficiency. Through the movable setting of the stirring shaft 5, when cleaning the used slurry mixing barrel 3, the stirring shaft 5 can be moved upward, so that the fan blades on the stirring shaft 5 are separated from the slurry mixing barrel 3, so that they are fully exposed, which is convenient for high-pressure water gun flushing and wire brushing, and further improves its practicality.

[0020] Specifically, the driving mechanism 6 includes a dual-axis motor 61, two fixed shafts 62, two conical friction wheels 64, two spline telescopic shafts 65, two matching wheels 66, two first bevel gears 67, two second bevel gears 68 and a limiting sleeve 15. The dual-axis motor 61 is connected to the rotating table 2, and the two fixed shafts 62 correspond to the bracket 4 one by one. The fixed shaft 62 is rotatably connected to the bracket 4. The fixed shaft 62 is linked to the dual-axis motor 61 through a pulley group 63. The two conical friction wheels 64 are connected to the fixed shaft 62 one by one. The two spline telescopic shafts 65 are connected to the fixed shaft 62 one by one. One by one, the spline telescopic shaft 65 is rotatably connected to the corresponding bracket 4, the two mating wheels 66 are connected to the spline telescopic shaft 65 in a one-to-one correspondence, the mating wheel 66 is in abutment with the conical friction wheel 64, the two first bevel gears 67 are connected to the spline telescopic shaft 65 in a one-to-one correspondence, the two second bevel gears 68 are spline-matched with the stirring shaft 5 in a one-to-one correspondence, the second bevel gear 68 is rotatably connected to the corresponding bracket 4, the second bevel gear 68 is engaged with the corresponding first bevel gear 67, the stirring shaft 5 is connected to a limiting sleeve 15, and the limiting sleeve 15 is matched with the second bevel gear 68.

[0021] In the above embodiment, when slurry mixing is carried out, the dual-axis motor 61 drives the pulley group 63, the pulley group 63 drives the corresponding fixed shaft 62 to rotate, and the fixed shaft 62 drives the corresponding conical friction wheel 64, and then transmits the power to the matching wheel 66, the spline telescopic shaft 65, the first bevel gear 67, the second bevel gear 68 and the stirring shaft 5, driving the stirring shaft 5 to stir and mix the slurry, while the stirring shaft 5 in the cleaning area does not rotate, the spline telescopic shaft 65 on this side contracts, the matching wheel 66 separates from the conical friction wheel 64, and the limit sleeve 15 limits the downward movement of the stirring shaft 5. When the stirring shaft 5 moves downward due to gravity, the limit sleeve 15 abuts against the second bevel gear 68 to prevent the stirring shaft 5 from moving down to the bottom of the slurry mixing barrel 3 and getting stuck.

[0022] Specifically, it also includes two rotating sleeves 7 and a screw rod 8. The two rotating sleeves 7 are correspondingly connected to the matching wheels 66 for rotation. The rotating sleeves 7 are rotatably connected to the screw rod 8, and the screw rod 8 is screwed to the bracket 4.

[0023] In the above embodiment, the rotating sleeve 7 is driven to move by rotating the screw rod 8, and the rotating sleeve 7 drives the matching wheel 66 to move, so that the corresponding matching wheel 66 is separated from the conical friction wheel 64, thereby realizing power cut-off.

[0024] Specifically, it also includes a slide 9, a support arm 10, an electric cylinder 11 and two clamping arms 12. The slide 9 is connected to the machine base 1, the support arm 10 is slidably connected to the slide 9, the electric cylinder 11 is connected to the slide 9, the output shaft of the electric cylinder 11 is connected to the support arm 10, and the two clamping arms 12 are rotatably connected to both sides of the support arm 10. The clamping arms 12 are used to clamp the corresponding stirring shaft 5.

[0025] In the above embodiments, when performing cleaning operations, the clamping arms 12 on both sides can be rotated to clamp the stirring shaft 5 in the cleaning area, and the electric cylinder 11 can be operated to drive the support arm 10 and the clamping arm 12 to move upward, so that the stirring shaft 5 moves upward and separates from the slurry mixing barrel 3, making it convenient to clean the slurry mixing barrel 3 and the fan blades on the stirring shaft 5.

[0026] Specifically, it also includes a rotary cylinder 13 and a bolt 14 . The rotary cylinder 13 is connected to the machine base 1 . The output shaft of the rotary cylinder 13 is connected to the rotary table 2 . The bolt 14 securely connects the two clamping arms 12 .

[0027] In the above embodiment, the rotary cylinder 13 drives the rotary table 2 to rotate, and the bolt 14 realizes the fixing operation of the two clamping arms 12.

[0028] The working principle of the utility model is as follows: slurry is mixed in one of the slurry mixing barrels 3, which is connected to the grouting pump through a pipeline. The double-axis motor 61 drives the corresponding pulley group 63. The conical friction wheel 64 and the matching wheel 66 at this position are in an engaged state. The power of the double-axis motor 61 is transmitted to the fixed shaft 62, the spline telescopic shaft 65, the first bevel gear 67 and the second bevel gear 68, and finally drives the stirring shaft 5 to rotate to perform the stirring operation;

[0029] At this time, the stirring shaft 5 in the cleaning area is not running, that is, the conical friction wheel 64 and the matching wheel 66 on this side are in a separated state, which is achieved by rotating the screw 8;

[0030] After the slurry in the first slurry mixing barrel 3 is used up, the grouting pipeline is disconnected, the rotary cylinder 13 is operated to drive the rotary table 2 to rotate, the spare slurry mixing barrel 3 is switched to perform slurry mixing operations, and the replaced slurry mixing barrel 3 is cleaned at the same time. The power of the slurry mixing area is connected, and the power of the cleaning area is disconnected. The two clamping arms 12 are pushed to rotate to clamp the stirring shaft 5 in the cleaning area. The two clamping arms 12 are fixed by bolts 14, and the electric cylinder 11 is operated to drive the support arm 10 to move upward. The stirring shaft 5 is splined with the corresponding second bevel gear 68, and the stirring shaft 5 is moved upward, so that the fan blades of the stirring shaft 5 and the inner wall of the slurry mixing barrel 3 are fully exposed, and high-pressure water washing and wire brushing are carried out for standby.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
