Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a tunnel construction grouting device, including a cart 5, a concrete tank 1 and a feed pump 2 are fixedly installed on the top of the cart 5, the feed end of the feed pump 2 is connected to the interior of the concrete tank 1 through a pipeline, the discharge end of the feed pump 2 is connected to a feed pipe 3, the top end of the feed pipe 3 is connected to a hose 4, and a grouting adjustment mechanism 6 is fixedly installed on the top of the cart 5;

[0024] The grouting adjustment mechanism 6 includes a fixing seat 1 601, the inner wall of the fixing seat 1 601 is rotatably connected to the rotating shaft 2 609 through a bearing, the outer wall of the rotating shaft 2 609 is fixedly sleeved with a column 602, the top of the column 602 is fixedly installed with a fixing seat 2 603, a hollow block 604 is rotatably provided inside the fixing seat 2 603, the top of the hollow block 604 is fixedly installed with a rotating shaft 1 608, the top of the rotating shaft 1 608 passes through the top of the fixing seat 2 603 through a bearing, the right end of the hose 4 is connected to the inside of the hollow block 604, the right outer wall of the hollow block 604 is fixedly installed with a mounting cylinder 605, the inner wall of the mounting cylinder 605 is rotatably connected to the grouting pipe 606 through a bearing, and the left end of the grouting pipe 606 extends into the hollow The grouting pipe 606 is in the block 604, and the grouting pipe 606 is rotatably connected to the hollow block 604. The bottom end of the grouting pipe 606 is connected to a grouting head 607. By rotating the grouting head 607, the hollow block 604 is driven to rotate, and then the mounting barrel 605 is driven to rotate, so that the grouting pipe 606 is rotated, and then the grouting head 607 is driven to rotate, and the direction is adjusted. By rotating the column 602, the fixing seat 603 is driven to rotate, and then the hollow block 604 is driven to rotate, and then the direction of the grouting head 607 is adjusted. By rotating the grouting pipe 606, the grouting head 607 is driven to rotate, and then the direction is adjusted, realizing adjustment of three different levels of direction, ensuring that the grouting head 607 can be adjusted in position and angle up and down, tilted and rotated one circle;

[0025] A limiting component 1 7 is provided between the grouting pipe 606 and the mounting cylinder 605 , a limiting component 2 8 is provided between the fixing seat 2 603 and the rotating shaft 1 608 , and a limiting component 3 9 is provided between the fixing seat 1 601 and the rotating shaft 2 609 ;

[0026] The limiting component 17 includes a slide groove 701 and a fixed ring 702. The slide groove 701 is opened on the right end port of the installation cylinder 605. The fixed ring 702 is fixedly mounted on the grouting pipe 606. The left outer wall of the fixed ring 702 is fixedly mounted with a slide rod 703. The outer wall of the slide rod 703 is slidably mounted with a slide ring 704. The slide ring 704 is slidably mounted on the grouting pipe 606. The outer wall of the slide ring 704 is fixedly mounted with a magnet block 705. The magnet block 705 is slidably mounted in the slide groove 7. 01, the magnet block 705 is stuck in the slide groove 701, so that the grouting pipe 606 cannot rotate relative to the mounting barrel 605. When the grouting pipe 606 needs to be rotated relative to the mounting barrel 605, it is only necessary to pull the sliding ring 704 to the right to disengage the magnet block 705 from the slide groove 701. Because the magnet block 705 is magnetic, it can be adsorbed on the mounting barrel 605, so that when the mounting barrel 605 is tilted, the magnet block 705 will not actively slide out of the slide groove 701;

[0027] The second limiting component 8 includes a turntable 801 and a limiting column 804. The turntable 801 is fixedly mounted on the top of the grouting head 607. The limiting column 804 is fixedly mounted on the top of the second fixing seat 603. The outer wall of the turntable 801 is provided with a slot 802. The outer wall of the limiting column 804 is slidably sleeved with a T-shaped plate 803. The end of the T-shaped plate 803 is snapped into the slot 802. The T-shaped plate 803 is snapped into the slot 802 to limit the turntable 801, so that the turntable 801 cannot rotate, and thus the rotating shaft 608 cannot rotate, that is, to prevent the hollow block 604 from rotating relative to the second fixing seat 603 after the direction is adjusted.

[0028] The limiting component 3 9 includes a second turntable 901 and a fixed plate 904. The second turntable 901 is fixedly mounted on the end of the second rotating shaft 609. The fixed plate 904 is fixedly mounted on the outer wall of the hollow block 604. A socket 902 is provided on the outer wall of the second turntable 901. A plug rod 903 is slidably provided on the inner wall of the fixed plate 904. The bottom end of the plug rod 903 is inserted into the socket 902. By inserting the plug rod 903 into the socket 902, the second turntable 901 is limited so that the second turntable 901 cannot rotate, and thus the second rotating shaft 609 cannot rotate, that is, it is prevented that the second rotating shaft 609 rotates after the direction is adjusted, causing the column 602 to rotate.

[0029] A handle 10 is fixedly mounted on one end of the magnet block 705 away from the sliding ring 704. The outer wall of the handle 10 is provided with anti-slip grooves. The provision of the handle 10 makes it easier to pull the magnet block 705 to move.

[0030] A handle 11 is fixedly installed on the top of the insertion rod 903. The diameter of the handle 11 is larger than the diameter of the insertion rod 903. The handle 11 is located above the fixed plate 904. The provision of the handle 11 can prevent the insertion rod 903 from falling off from the fixed plate 904 on the one hand, and make it easier to pull the handle 11 on the other hand.

[0031] Working principle: When in use, the feed pump 2 works to pump the concrete in the concrete tank 1 into the feed pipe 3, and then into the hose 4. The concrete enters the hollow block 604 from the hose 4, and then enters the grouting pipe 606, and is ejected from the grouting head 607 for grouting. When the position and angle of the grouting head 607 need to be adjusted, the grouting pipe 606 can be directly rotated to drive the grouting head 607 to make a circular motion, so as to point the grouting head 607 upward, or the rotating shaft 1 608 can be rotated to drive the hollow block 604 to rotate, and then drive the mounting barrel 605 to rotate. The rotation of the mounting barrel 605 drives the grouting pipe 606 to rotate, and then drives the grouting head 607 to rotate, and adjust the angle of the grouting head 607. The column 602 can also be rotated to drive the fixing seat 2 603 to rotate, and then drive the hollow block 604 to rotate, so as to tilt the grouting head 607.

[0032] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
