Personnel are required to lift the grouting machine to a certain height to pass over the ground protrusions. It is inconvenient to push the grouting frame on the rugged mountain roads. Therefore, improvements are needed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, the utility model provides a technical solution: a pre-grouting construction structure for highway construction, including a base plate 1, a barrel 2 is fixedly installed on the top of the base plate 1, a rotating motor 3 is fixedly installed on the top of the base plate 1 on one side of the barrel 2, and a rotating shaft 4 is fixedly installed on the output end of the rotating motor 3. The rotating shaft 4 penetrates the barrel 2 and is rotatably connected to the barrel 2, and a spiral blade 5 is fixedly installed on the surface of the rotating shaft 4 located inside the barrel 2. A valve 6 is provided at one end of the barrel 2 away from the rotating motor 3. By providing the rotating motor 3 and the spiral blade 5, after pouring the slurry into the barrel 2, the rotating motor 3 is started to drive the spiral blade 5 to rotate at the bottom of the barrel 2, and the slurry is transferred to the valve 6, and the valve 6 is opened. As the spiral blade 5 continuously transfers the slurry, the slurry is discharged from the valve 6 for grouting.

[0021] A circular plate 101 is fixedly installed on the top of the bottom plate 1, and rectangular grooves 102 are provided at the four corners of the circular plate 101. Mounting plates 14 are symmetrically provided on both sides of the bottom plate 1 at the bottom of the circular plate 101. Rubber rings 15 are symmetrically provided on both sides of the mounting plates 14, and buffer rods 16 are slidably installed inside the rubber rings 15. Because the rubber rings 15 are provided, the buffer rods 16 slide inside the rubber rings 15, so that the rubber rings 15 and the buffer rods 16 rub against each other to generate a damping effect, thereby achieving buffering and shock reduction of the roller 24;

[0022] The bottom ends of the two groups of buffer rods 16 are fixedly mounted with connecting plates 17, and the surface of the buffer rods 16 between the mounting plate 14 and the connecting plate 17 is provided with a buffer spring 18. Due to the provision of the buffer spring 18, the buffer spring 18 is compressed, deformed and rebounded between the mounting plate 14 and the connecting plate 17, pressing the roller 24 down to the ground, thereby preventing the roller 24 from being suspended in the air when the bottom plate 1 is pushed to move;

[0023] The top end of the buffer rod 16 passes through the mounting plate 14 and is fixedly installed with a limit plate 19, and support plates 20 are fixedly installed at both ends of the bottom of the connecting plate 17. A rotating column 21 is fixedly installed between the two groups of support plates 20, and a fixed frame 22 is rotatably installed at one end of the rotating column 21 located on the outer side of the support plate 20, and three groups of mounting frames 23 are fixedly installed at equal angles on the surface of the fixed frame 22, and a roller 24 is rotatably installed at one end of the mounting frame 23 away from the fixed frame 22. By providing the fixed frame 22, the three groups of mounting frames 23 and the rollers 24 are fixed at equal angles on the surface of the fixed frame 22 to ensure that when one group of rollers 24 is obstructed during its movement, the fixed frame 22 can rotate around the rotating column 21, so that the three groups of rollers 24 rotate synchronously to overcome the obstruction.

[0024] A fixing plate 7 is fixedly installed at the four corners of the top of the circular plate 101, a clamping rod 8 is slidably installed on one side of the fixing plate 7, and one end of the clamping rod 8 passes through the fixing plate 7 and is fixedly installed with an L-shaped clamping plate 9. A fixing bolt 10 is provided on the top of the L-shaped clamping plate 9, and the bottom end of the fixing bolt 10 passes through the L-shaped clamping plate 9 and is connected to the bottom plate 1. By providing the fixing bolt 10, after the clamping strip 13 is clamped into the corresponding clamping block 25, the fixing bolt 10 is tightened to clamp and fix the clamping rod 8 and the clamping strip 13 to ensure that the clamping strip 13 will not easily separate from the clamping block 25.

[0025] A top plate 11 is fixedly installed at one end of the fixing bolt 10 away from the L-shaped clamping plate 9, and a clamping spring 12 is provided on the surface of the clamping rod 8 located between the fixing plate 7 and the top plate 11. Because of the clamping spring 12, the top plate 11 and the clamping strip 13 are pushed toward the clamping block 25 under the elastic action of the clamping spring 12, thereby clamping and fixing the clamping block 25.

[0026] A clamping block 25 is symmetrically fixedly installed on the top of the mounting plate 14, and a clamping groove 26 is provided on one side of the clamping block 25, and the clamping block 25 corresponds to the rectangular groove 102. A clamping strip 13 is fixedly installed between the two sets of top plates 11 on the same side of the top of the return plate 101, and the clamping strip 13 corresponds to the clamping groove 26. Because the clamping strip 13 and the clamping groove 26 are provided, when the clamping block 25 passes through the rectangular groove 102 so that the clamping groove 26 is located at the top of the return plate 101, it is ensured that the clamping strip 13 can be clamped into the corresponding clamping groove 26, and the clamping block 25 is clamped and fixed, and the mounting plate 14 is clamped and fixed to the bottom of both sides of the return plate 101.

[0027] The working principle of the utility model is:

[0028] Loosen the fixing bolts 10, pull the two groups of L-shaped card plates 9 on the same side of the top of the return plate 101, drive the top plate 11 and the card strip 13 away from the rectangular groove 102, place the mounting plate 14 on the bottom of the return plate 101, make the card block 25 pass through the rectangular groove 102 until the card slot 26 corresponds to the card strip 13, loosen the L-shaped card plate 9, under the elastic action of the clamping spring 12, push the top plate 11 and the card strip 13 toward the card block 25, make the two ends of the card strip 13 snap into the corresponding card slots 26, tighten the fixing bolts 10, clamp and fix the L-shaped card plate 9, and push the bottom plate When moving on the mountainous ground, the roller 24 moves up and down with the ruggedness of the ground, so that the buffer spring 18 is compressed and rebounded on the surface of the buffer rod 16, and the buffer rod 16 is controlled to slide up and down inside the rubber ring 15, so as to buffer and reduce the movement of the roller 24. At the same time, when encountering a ground bump that hinders the roller 24 from moving forward, the three groups of rollers 24 can rotate around the rotating column 21, pass over the ground bump, push the bottom plate 1 to the specified position, and then pour the slurry into the barrel 2, start the rotating motor 3 to control the spiral blade 5 to transfer the slurry to the valve 6 for discharge for grouting.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
