Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0048] As Figures 1-15 shown, the present invention has the following four specific embodiments.

[0049] Embodiment 1

[0050] A road and bridge engineering management foundation maintenance device, comprising:

[0051] A base 1, a through groove 11 is opened at the center of the base 1, sand and gravel boxes 12 are symmetrically fixed on the left and right sides of the through groove 11, a rubber material box 13 is fixed between the tops of the sand and gravel boxes 12, an adding pipe 14 is fixed on the top of the rubber material box 13, the rubber material box 13 is used for containing crack repair glue, the bottom of the sand and gravel box 12 is inclined downward along the direction pointing to the center of the through groove 11, and a discharge port 15 is opened at the bottom of the sand and gravel box 12 on the side close to each other, a sliding groove 16 is opened in the sand and gravel box 12 corresponding to the discharge port 15, a sliding cavity 17 is opened in the sand and gravel box 12 above the sliding groove 16, a sealing plate 18 is slidably connected in the sliding groove 16, a sliding rod 19 is longitudinally and evenly fixed on the top of the sealing plate 18, the top of the sliding rod 19 extends into the sliding cavity 17 and is fixed with a sliding plate 110, the sliding plate 110 is slidably connected in the sliding cavity 17, and a through hole 111 is opened on the sliding plate 110, a first spring 112 is sleeved on the sliding rod 19, and a lifting plate 113 is fixed on the upper part of the sealing plate 18;

[0052] A ramming base 2, four telescopic rods 21 are fixedly connected in a rectangle between the ramming base 2 and the rubber material box 13, and a second spring 22 is sleeved outside the telescopic rods 21;

[0053] A glue supply mechanism for transporting the crack repair glue in the rubber material box 13 to the position of the discharge port 15;

[0054] An energy storage mechanism for realizing the energy storage and rising of the ramming base 2 and the rapid impact and falling;

[0055] A driving mechanism for providing power for the energy storage mechanism.

[0056] Further, when the sliding plate 110 contacts the bottom of the sliding cavity 17, the first spring 112 is in a natural state.

[0057] In this embodiment, as Figures 1-6As shown, when the device is working, the sand and gravel are filled into the sand and gravel box 12, and the crack repair glue is added to the glue box 13 through the adding pipe 14. Then the device is moved to the position where there are cracks on the foundation.

[0058] The driving mechanism provides power for the energy storage mechanism. When the energy storage mechanism works, it realizes the energy storage and rising of the ramming seat 2 and the rapid impact and falling. When the ramming seat 2 is located below the lifting plate 113, under the action of the first spring 112, the sealing plate 18 closes the discharge port 15.

[0059] When the ramming seat 2 stores energy and rises, when the ramming seat 2 starts to contact the lifting plate 113, it will drive the sealing plate 18 to rise, so that the discharge port 15 is opened. The sand and gravel in the sand and gravel box 12 fall to the crack position through the position of the discharge port 15. When the ramming seat 2 rapidly impacts and falls, it will drive the sand and gravel into the foundation system at the crack position. On the one hand, it can repair the crack, and on the other hand, it can strengthen the strength of the crack position and avoid the recurrence of cracks. Continuous operation of the driving mechanism can realize continuous driving of the sand and gravel into the foundation system.

[0060] When the ramming seat 2 impacts and falls, under the action of the first spring 112, the sealing plate 18 resets and closes the discharge port 15 again.

[0061] The glue supply mechanism is used to transport the crack repair glue in the glue box 13 to the position of the discharge port 15 and mix it with the sand and gravel falling from the position of the discharge port 15. The crack repair glue can improve the adhesion between the sand and gravel itself and between the sand and gravel and the foundation system, and improve the strength of the repaired foundation.

[0062] The setting of the through hole 111 makes the air pressure on both sides of the sliding plate 110 the same, so that the sliding plate 110 can freely lift in the sliding cavity 17, and then realize the lifting of the sealing plate 18.

[0063] Embodiment 2

[0064] The glue supply mechanism includes a cover cylinder 31, a glue supply pipe 32, and a piston 33; the cover cylinder 31 is fixedly connected to the center of the glue box 13, and a group of glue supply pipes 32 are longitudinally and evenly fixedly connected to the inner side plates of the gravel boxes 12 close to each other. The bottom of the glue supply pipe 32 extends into the discharge port 15, and the top of the glue supply pipe 32 extends into the glue box 13. The heads of each group of glue supply pipes 32 are integrally fixedly connected with a transfer pipe 34, and the transfer pipe 34 is connected to the upper part of the cover cylinder 31 through a glue outlet pipe 35. The upper parts of the front and rear sides of the cover cylinder 31 are fixedly connected with a glue inlet pipe 36. A first one-way valve 37 and a second one-way valve 38 are fixedly connected in the glue outlet pipe 35 and the glue inlet pipe 36 respectively. The direction in which the first one-way valve 37 allows fluid to pass is away from the inner cavity of the cover cylinder 31, and the direction in which the second one-way valve 38 allows fluid to pass is towards the inner cavity of the cover cylinder 31. The piston 33 is hermetically and slidably connected in the cover cylinder 31. The bottom of the piston 33 is fixedly connected with a connecting cylinder 39, and the connecting cylinder 39 is slidably connected to the bottom plate of the glue box 13. Openings 310 are evenly arranged in a circle on the side plate of the connecting cylinder 39. A top block 311 is slidably connected in the connecting cylinder 39, and a top rod 312 is fixedly connected between the top block 311 and the ramming seat 2. The top rod 312 is slidably connected to the bottom plate of the connecting cylinder 39.

[0065] Further, the inclination of the bottom of the glue supply pipe 32 is the same as that of the discharge port 15.

[0066] In this embodiment, as Figure 3 , 7 and Figure 9 show, when the ramming seat 2 rises, it will drive the top rod 312 and the top block 311 to rise. When the ramming seat 2 contacts the lifting plate 113, the top block 311 contacts the piston 33. During the continuous rise of the ramming seat 2, on the one hand, it drives the sealing plate 18 to rise through the lifting plate 113 to open the discharge port 15 to realize the falling of gravel; on the other hand, it drives the piston 33 to rise through the top block 311. As Figure 10 and 11 show, when the piston 33 rises, the crack repair glue in the cover cylinder 31 is extruded through the glue outlet pipe 35 and the first one-way valve 37, and is successively extruded to the discharge port 15 through the transfer pipe 34 and the glue supply pipe 32. That is, during the rise of the ramming seat 2, the gravel falls through the discharge port 15, and the crack repair glue enters the position of the discharge port 15 and is mixed with the falling gravel. Since the inclination of the bottom of the glue supply pipe 32 is the same as that of the discharge port 15, when the crack repair glue is ejected from the bottom of the glue supply pipe 32, it will wash down the gravel at the position of the discharge port 15, avoiding the blockage of the discharge port 15.

[0067] When the ramming seat 2 impacts and descends, the sealing plate 18 is reset under the action of the first spring 112, and the top block 311 first descends in the connecting cylinder 39. When the top block 311 contacts the bottom of the connecting cylinder 39, the continuous descent of the ramming seat 2 will pull the connecting cylinder 39 and the piston 33 to descend, and the crack repair glue enters the cover cylinder 31 through the glue inlet pipe 36 and the second one-way valve 38.

[0068] As Figure 9 shown, the opening 310 is provided so that the air pressure on the lower surface of the piston 33 and on both the upper and lower sides of the top block 311 is the same as the external atmospheric pressure, enabling the top block 311 and the piston 33 to move smoothly.

[0069] Embodiment 3

[0070] The energy storage mechanism includes a suspension plate 41, a slide rail 42, and a lifting roller 43; the suspension plate 41 is L-shaped, and a pair of suspension plates 41 are fixedly connected to the front and rear sides of the ramming base 2 respectively.

A seat plate 48 is fixedly connected between the tops of the slide rails 42. The lifting roller 43 is rotatably connected between the seat plate 48 and the base 1 through a rotating shaft 49. Vertically arranged impact grooves 410 are symmetrically formed on the roller surface of the lifting roller 43. The bottom of one impact groove 410 is docked with the top of the other impact groove 410 through a spiral lifting groove 411. The lifting rod 47 is slidably connected in the impact groove 410 and the lifting groove 411, and a driving mechanism is used to drive the lifting roller 43 to rotate.

[0071] In this embodiment, as Figure 7 and 8 shown, the driving mechanism is used to drive the lifting roller 43 to rotate. Assuming that when looking from top to bottom, the lifting roller 43 rotates clockwise, and in the initial state, the lifting rod 47 is located at the bottom of the impact groove 410. During the process of the lifting roller 43 rotating half a circle, the lifting rod 47 rises in the lifting groove 411, and the lifting seat 44, the suspension plate 41, and the ramming base 2 rise synchronously. During this process, the second spring 22 is compressed to store energy, thereby realizing the energy storage and rising of the ramming base 2. When the lifting rod 47 moves to the top of the impact groove 410, under the action of the second spring 22, the ramming base 2 rapidly impacts and descends.

[0079] Adjust the position of the mounting bracket 612 so that the second driving gear 618 meshes with the second transmission gear 69, that is Figure 13 the state shown. When the motor 510 drives the driving shaft 53 to rotate, the rotating sleeve, the first driving gear 511, and the second driving gear 618 rotate synchronously. The first driving gear 511 idles, and the second driving gear 618 drives the second transmission gear 69 meshing with it to rotate, so that the second transmission shaft 66 and the second driving wheel 67 rotate. As Figure 2 and 12 shown, under the action of the second belt 68, the second driven wheel 63 rotates, and then the axle 61 and the pressing roller 62 rotate.

[0080] When the second transmission shaft 66 rotates, it also drives the driving bevel gear 619 to rotate, and the driven bevel gear 621 meshing with it rotates, so that the mounting shaft 620 and the tooth rake 622 rotate. When the tooth rake 622 rotates, it can rake the uneven positions on the foundation flat. When the pressing roller 62 rotates, on the one hand, it can press the raked foundation flat, and on the other hand, it can also move the device to achieve the purpose of inspection. The universal wheels 64 can make the device have a steering function, and the moving direction of the device can be controlled through the handle 65.

[0081] In the crack repair mode

[0082] During the inspection process, when a crack is found, the motor 510 is braked and the device stops, so that the ramming seat 2 is located directly above the crack. Move the mounting bracket 612 backward, and the second driving gear 618 is separated from the second transmission wheel and the first driving gear 511 meshes with the first transmission gear 59.

[0083] When the motor 510 drives the driving shaft 53 to rotate, the rotating sleeve, the first driving gear 511, and the second driving gear 618 rotate synchronously. The second driving gear 618 idles, and the first driving gear 511 drives the first transmission gear 59 meshing with it to rotate, so that the first transmission shaft 52 and the first driving wheel 57 rotate. As Figure 12 shown, under the action of the first belt 58, the first driven wheel 55 rotates, and then the worm 51 rotates, and the worm gear 54 meshing with it rotates, and then the rotating shaft 49 and the lifting roller 43 rotate. When the lifting roller 43 rotates, the crack is repaired.

[0084] It should be noted that when the device is moving, the ramming base 2 needs to be moved upward to separate from the ground. However, the ramming base 2 cannot rise too far to cause the sealing plate 18 to open. That is, when the device is moving, the ramming base 2 should be located above the ground and below the lifting plate 113 in the closed state. In the present application, the lead angle of the worm 51 is smaller than the equivalent friction angle between the meshing teeth of the worm 51 and the worm wheel 54, so that the worm 51 and the worm wheel 54 have the ability of self-locking. When the ramming base 2 is located above the ground, due to the existence of self-locking, the ramming base 2 will not descend, enabling the device to move smoothly.
