[0063] The embodiment of the present application provides a double-head circulating pressure grouting machine for foundation treatment.

[0064] In the description of the embodiment of the present application, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "arrangement", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0065] As Figure 1 and Figure 2As shown in the drawings, the double-head circulating pressure grouting machine for foundation treatment of the embodiment of the present application comprises a storage tank 10 and a grouting body 20. The storage tank 10 is used for storing cement, and the grouting body 20 is used for delivering the cement in the storage tank 10 to the foundation after pressurization. The grouting body 20 adopts the prior art, and the specific structure is not described herein. The bottom of the grouting body 20 is fixed with a base 30. The base 30 is provided with a roller assembly 40 and a stabilizing assembly 50. The roller assembly 40 can move up and down along the height of the base 30, and can extend out of or retract into the base 30. The stabilizing assembly 50 can move horizontally along the base 30, and can extend out of or retract into the base 30. When the roller assembly 40 retracts into the base 30, the stabilizing assembly 50 can extend out of the base 30 and contact the ground. When it is necessary to move the pressure grouting machine, the roller assembly 40 extends out of the base 30 and contacts the ground, and the stabilizing assembly 50 retracts into the base 30, so that the movement is more convenient. When the pressure grouting machine delivers cement, the roller assembly 40 retracts into the base 30 and is separated from the ground, so that the bottom of the base 30 contacts the ground. The displacement caused by vibration is effectively reduced, and the stability of the pressure grouting machine during use is improved. At this time, the stabilizing assembly 50 extends out of the base 30 and contacts the ground, so that the support area of the base 30 is increased, and the stability of the pressure grouting machine is further improved.

[0066] Specifically, as shown in the drawings, Figure 3 The roller assembly 40 comprises a rotating rod 41, a rotating lever 42 and a roller 43. The rotating rod 41 is arranged in the base 30 and is rotationally connected with the base 30. One end of the rotating lever 42 is threadedly connected with the rotating rod 41. The roller 43 is arranged in a first groove 44 of the base 30 and is connected with the other end of the rotating lever 42. The number of the roller assemblies 40 is not limited, and preferably, two roller assemblies 40 are arranged symmetrically on the base 30. In the embodiment, the roller 43 is mounted on a horizontally arranged fixing plate 45. The first groove 44 is adapted to the fixing plate 45. The top of the fixing plate 45 is fixedly connected with a vertical rotating lever 42. One end, i.e. the top end, of the rotating lever 42 away from the fixing plate 45 is threadedly connected with the rotating rod 41. When the rotating rod 41 rotates, the rotating lever 42 moves up and down through the thread, thereby driving the roller 43 to move up and down, so that the roller 43 extends out of or retracts into the first groove 44. When the roller 43 extends out of the first groove 44, it directly contacts the ground, so that the base 30 is isolated from the ground, which is more conducive to the movement of the pressure grouting machine. When the roller 43 retracts into the first groove 44, the roller 43 is separated from the ground, so that the base 30 contacts the ground. When the pressure grouting machine is in normal use, the displacement caused by vibration can be effectively reduced, and the stability of the pressure grouting machine is ensured.

[0067] Specifically, as shown in the drawings, Figure 4As shown, the rotating rod 41 is provided with a first driving assembly 46, which comprises a worm wheel 461, a worm 462 and a rotating handle assembly 463. The worm wheel 461 is arranged on the rotating rod 41 and is fixedly connected to the rotating rod 41 by being sleeved on the outside of the rotating rod 41. The worm 462 is arranged in the base 30 and is rotatably connected to the base 30. The worm 462 is engaged with the worm wheel 461. The rotating handle assembly 463 is arranged at one end of the worm 462. Rotating the rotating handle assembly 463 drives the worm 462 to rotate, and the worm 462 drives the worm wheel 461 to rotate, so that the rotating rod 41 rotates, thereby moving the rollers 43 up and down.

[0068] Specifically, as shown in the figure, Figure 5 As shown, the rotating handle assembly 463 comprises a rotating handle 4631 and a limiting rod 4632. One end of the rotating handle 4631 is arranged in the worm 462, and the other end is arranged outside the worm 462. The rotating handle 4631 is circumferentially engaged with the worm 462 and is axially movably connected to the worm 462. The limiting rod 4632 is arranged at the end of the rotating handle 4631 outside the worm 462 and can be engaged with or separated from the base 30 along with the movement of the rotating handle 4631. In this embodiment, the rotating handle 4631 is coaxially arranged with the worm 462, one end of the rotating handle 4631 is sleeved in the worm 462, and the other end is arranged outside the worm 462. The rotating handle 4631 is symmetrically provided with first engaging blocks 4633 on both sides. The position of the worm 462 relative to the rotating handle 4631 is provided with a limiting groove 4634. The limiting groove 4634 is arranged along the axial direction of the worm 462. The first engaging blocks 4633 are engaged with the limiting groove 4634, so that the rotating handle 4631 is circumferentially engaged with the worm 462, thereby enabling the rotating handle 4631 to drive the worm 462 to rotate. The first engaging blocks 4633 can move along the limiting groove 4634, so that the rotating handle 4631 is axially movably connected to the worm 462, thereby enabling the rotating handle 4631 to move axially. The rotating handle 4631 is fixedly provided with a rotating disc 4635 at the end thereof outside the worm 462. The rotating disc 4635 is fixedly provided with the limiting rod 4632 on the side close to the base 30. The base 30 is provided with a positioning groove 4636 at the position opposite to the rotating disc 4635. The limiting rod 4632 can be engaged with the positioning groove 4636 along with the axial movement of the rotating handle 4631. The rotating disc 4635 is fixedly provided with a handle 4637 on the side away from the base 30. When it is needed to rotate the worm 462, the handle 4637 is pulled to move the rotating handle 4631 outwardly from the worm 462, and the limiting rod 4632 is disengaged from the positioning groove 4636. At this time, the rotating handle 4631 drives the worm 462 to rotate. When it is not needed to rotate the worm 462, the handle 4637 is pushed to move the rotating handle 4631 inwardly from the worm 462, and the limiting rod 4632 is engaged with the positioning groove 4636, thereby preventing the rotating handle 4631 from driving the worm wheel 461 to rotate.

[0069] Preferably, the handle 4631 is provided with a first spring 4638 at one end of the worm 462, the first spring 4638 is connected to the worm 462 at one end and connected to the end of the handle 4631 at the other end. Pull the handle 4637, the handle 4631 moves outwardly from the worm 462, the first spring 4638 is elongated, the handle 4637 is released, the first spring 4638 rebounds, and the handle 4631 moves inwardly from the worm 462, so that the limiting rod 4632 is automatically engaged with the positioning groove 4636.

[0070] Specifically, as shown in Figure 6 The stabilizing assembly 50 includes a gear 51, a rack 52 and a stabilizing plate 53. The gear 51 is arranged on the worm 462, the rack 52 is arranged in the base 30 and is engaged with the gear 51, the gear 51 can drive the rack 52 to move horizontally, and the stabilizing plate 53 is arranged in the second groove 56 of the base 30 and is connected with the rack 52. In this embodiment, the gear 51 is sleeved on the outside of the worm 462 and is fixedly connected with the worm 462, and the worm 462 drives the gear 51 to rotate. The base 30 is provided with a sliding groove 54 opposite the position of the rack 52, the gear 51 is engaged with the rack 52 and can drive the rack 52 to slide horizontally along the sliding groove 54. The bottom of the rack 52 is fixedly provided with a vertical connecting rod 55, and the bottom of the connecting rod 55 is fixedly provided with a horizontal stabilizing plate 53. The bottom of the base 30 is provided with a second groove 56 opposite the position of the stabilizing plate 53, and the second groove 56 is matched with the stabilizing plate 53. In order to facilitate the movement of the connecting rod 55, a communication groove 57 is arranged between the sliding groove 54 and the second groove 56. The rack 52 drives the connecting rod 55 to move, so that the horizontal stabilizing plate 53 can extend out of or retract into the second groove 56. When the pressure grouting machine is working normally, the roller assembly 40 retracts into the base 30 and is separated from the ground, the gear 51 drives the rack 52 to slide horizontally, so that the stabilizing plate 53 extends out of the second groove 56, the supporting area of the base 30 is increased, and the stability of the grouting machine is further improved.

[0071] Specifically, as shown in Figure 7 The storage tank 10 is provided with a stirring assembly 60, and the stirring assembly 60 includes a driving shaft 61, a stirring rod 63 and a scraper 64. One end of the driving shaft 61 is circumferentially clamped with the stirring shaft 62, the stirring shaft 62 is axially movably connected with the driving shaft 61, and the stirring shaft 62 can move along the driving shaft 61. The stirring rod 63 is arranged on the stirring shaft 62. The scraper 64 is arranged at the end of the stirring rod 63 away from the stirring shaft 62.

[0072] In the embodiment, the driving shaft 61 is vertically arranged at the top of the storage box 10 and is rotationally connected with the storage box 10. The driving motor 65 is connected with the driving shaft 61 for driving the driving shaft 61 to rotate. The stirring shaft 62 is externally sleeved with the end of the driving shaft 61 away from the driving motor 65, and the stirring shaft 62 is coaxially arranged with the driving shaft 61. The second clamping block 66 is symmetrically fixed with the end of the driving shaft 61 away from the driving motor 65, and the position of the stirring shaft 62 relative to the second clamping block 66 is provided with the limiting through slot 67 which is arranged along the axial direction of the stirring shaft 62. The second clamping block 66 is clamped with the limiting through slot 67, so that the driving shaft 61 is circumferentially clamped with the stirring shaft 62, thereby enabling the driving shaft 61 to drive the stirring shaft 62 to rotate. The second clamping block 66 can move along the limiting through slot 67, so that the driving shaft 61 is axially movably connected with the stirring shaft 62, thereby enabling the stirring shaft 62 to axially move, i.e. to move up and down. The stirring rods 63 are fixed on the stirring shaft 62 and are equally spaced along the height of the stirring shaft 62. The arc-shaped scraper 64 is fixed with the end of the stirring rod 63 away from the stirring shaft 62. The stirring shaft 62 drives the stirring rod 63 to rotate while synchronously driving the scraper 64 to rotate, and the scraper 64 can clean the cement adsorbed on the inner wall of the storage box 10, thereby avoiding the cement from being condensed on the inner wall of the storage box 10.

[0073] Specifically, as shown in Figure 8 the end of the stirring shaft 62 away from the driving shaft 61 is provided with the inclined slot 68, the position of the storage box 10 relative to the inclined slot 68 is provided with the clamping rod 69, the clamping rod 69 is clamped with the inclined slot 68, the driving shaft 61 drives the stirring shaft 62 to rotate, so that the clamping rod 69 moves along the inclined slot 68 and drives the stirring shaft 62 to move along the driving shaft 61. In the embodiment, the clamping rod 69 is fixed on the bottom of the storage box 10 through the support frame 691, and the stirring shaft 62 passes through the support frame 691 and is rotationally connected with the support frame 691. The inclined slot 68 is arranged at the bottom of the stirring shaft 62 and is obliquely arranged along the circumferential direction of the stirring shaft 62. The end of the clamping rod 69 is clamped with the inclined slot 68. When the driving shaft 61 drives the stirring shaft 62 to rotate, the clamping rod 69 moves along the inclined slot 68, and since the inclined slot 68 is obliquely arranged, the stirring shaft 62 is driven to move up and down along the driving shaft 61. When the stirring shaft 62 moves up and down, the stirring rod 63 is driven to move up and down, thereby enabling the stirring rod 63 to rotate while reciprocating up and down, thereby improving the stirring effect of the stirring rod 63. The bottom of the storage box 10 is provided with the closing valve 11, so that the well-stirred cement can enter the grouting body 20 from the storage box 10.

The number of the inlet 70 is not limited, in the embodiment, two inlets 70 are provided, which are symmetrically arranged on the two sides of the driving motor 65. By arranging the second driving assembly 72, the sealing plate 71 is driven to reciprocating rotate, so that the sealing plate 71 is opened or closed, and automatic quantitative feeding is realized.

[0075] Specifically, as shown in Figure 9 The second driving assembly 72 includes a support block 721, a connecting shaft 722, a second spring 723, a driven cone gear 724 and an incomplete cone gear 725. The support block 721 is fixed on the top of the storage box 10, and the connecting shaft 722 is installed on the support block 721 and is rotatably connected with the support block 721. One end of the connecting shaft 722 close to the inlet 70 is fixedly connected with the sealing plate 71. The second spring 723 is sleeved on one end of the connecting shaft 722 close to the inlet 70, one end of the second spring 723 is connected with the outer wall of the inlet 70, and the other end of the second spring 723 is connected with the connecting shaft 722. The end of the connecting shaft 722 away from the sealing plate 71 is fixedly connected with the driven cone gear 724. The outer part of the driving shaft 61 is sleeved with the incomplete cone gear 725, and the incomplete cone gear 725 is fixedly connected with the driving shaft 61. The incomplete cone gear 725 is not completely provided with the tapered teeth in the circumferential direction, and the part without the tapered teeth is provided with an opening.
