Detailed Description of the Embodiment

[0022] The following further details the present application with reference to the drawings.

[0023] The embodiment of the present application discloses a grouting device for highway construction.

[0024] Referring to Figure 1 , Figure 2 and Figure 3 as shown, a grouting device for highway construction includes a machine base 1, and a plurality of rollers 100 are rotatably arranged at the bottom of the machine base 1. A placement table 10 is fixedly installed above the machine base 1, a placement groove 11 is arranged on the placement table 10, and a circuit control box 2 with the bottom installed in the placement groove 11 is fixedly arranged on the machine base 1.

[0025] As Figure 2 , Figure 3 shown, two adjusting rods 3 are fixedly installed on the machine base 1 and located outside the placing table 10. The two adjusting rods 3 are on the same side of the placing table 10 and are arranged in parallel with each other. The length of the adjusting rod 3 extends along the height direction of the circuit control box 2. An elevating frame 4 is arranged outside the two adjusting rods 3. The elevating frame 4 is sleeved outside the circuit control box 2 and can move up and down along the length direction of the adjusting rod 3.

[0026] As Figure 2 , Figure 3 shown, a waterproof seal cover 5 covering the periphery of the circuit control box 2 is arranged between the elevating frame 4 and the placing table 10. The waterproof seal cover 5 can be telescopically folded along the length direction of the adjusting rod 3. The lower end of the waterproof seal cover 5 is fixedly arranged on the placing table 10, and the upper end of the waterproof seal cover 5 is fixedly arranged on the elevating frame 4. When the elevating frame 4 moves up and down along the length direction of the adjusting rod 3, the upper end of the corresponding waterproof seal cover 5 will move up and down synchronously with the elevating frame 4.

[0027] As Figure 2 , Figure 3 shown, a locking member 6 is threadedly connected to the connection part between the elevating frame 4 and the adjusting rod 3. In this embodiment, the locking member 6 is a bolt. A plurality of locking holes 30 are arranged on the adjusting rod 3, and the locking holes 30 are arranged at intervals in sequence along the length direction of the adjusting rod 3. The locking member 6 is used to be inserted into and threadedly connected to the respective opposite locking holes 30, and the elevating frame 4 is fixed at a specified height on the adjusting rod 3 by screwing the locking member 6 tightly.

[0028] As Figure 2 , Figure 3 shown, a plurality of inserting rods 40 are fixedly installed at the top of the elevating frame 4. A top cover 7 is detachably installed on the top of the elevating frame 4 through the inserting rods 40, and the top cover 7 is used to cover the top openings of the inserting rods 40. A fastening nut 70 is threadedly connected to the end of the inserting rod 40, and the top cover 7 is fixedly installed on the top of the elevating frame 4 through the fastening nut 70. By moving the elevating frame 4 up to an appropriate height and ensuring that the waterproof seal cover 5 smoothly covers the four sides of the circuit control box 2, then by inserting the locking member 6 into and threadedly connecting it to the locking hole 30 at an appropriate height, the elevating frame 4 can be fixed at this time. Then insert the top cover 7 outside the inserting rods 40, and finally tighten and fix the top cover 7 through the fastening nut 70. At this time, a relatively sealed space can be provided for the internal circuit control box 2, effectively preventing the adverse effects brought by external rainwater to the internal circuit control box 2, creating conditions for the construction of the circuit control box 2 in a harsh weather environment, further meeting the construction requirements, and improving the construction safety and stability.

[0029] As Figure 2 , Figure 3As shown in the figure, a plurality of guide rods 8 are fixedly installed on the machine base 1 outside the placement table 10. Each guide rod 8 is parallel to each other and symmetrically arranged on both sides of the placement table 10. The length direction of the guide rod 8 is consistent with the lifting direction of the lifting frame 4, and the lifting frame 4 is movably sleeved outside the guide rods 8 on both sides. The guide rod 8 can further improve the stability of the lifting frame 4 during lifting, ensure that the lifting frame 4 lifts along the specified route, and play a guiding role for the lifting frame 4.

[0030] As Figure 2 , Figure 3 shown in the figure, limit tube sleeves 9 are threadedly connected to the tops of both the guide rod 8 and the adjusting rod 3. The limit tube sleeve 9 is used to prevent the lifting frame 4 from detaching from the tops of the guide rod 8 and the adjusting rod 3. The maximum rising height of the lifting frame 4 is limited. When it is necessary to remove the lifting frame 4 from the guide rod 8 and the adjusting rod 3, after unscrewing the limit tube sleeve 9, the lifting frame 4 can be disassembled.

[0031] As Figure 2 , Figure 3 shown in the figure, a handrail 12 is fixedly installed on the machine base 1 outside the waterproof seal cover 5. The handrail 12 gradually inclines away from the machine base 1 from bottom to top. A storage box 13 is fixedly installed on the side wall of the handrail 12 away from the waterproof seal cover 5. The storage box 13 can not only meet the daily storage needs, but also place the disassembled top cover 7 in the storage box 13, which facilitates the storage of the top cover 7.

[0032] As Figure 3 , Figure 4 shown in the figure, a plurality of drain holes 14 penetrate through the bottom of the storage box 13. Through the drain holes 14, the rainwater that accidentally flows into the storage box 13 can be discharged from the storage box 13 in time, so as to ensure the dryness inside the storage box 13.

[0033] The implementation principle is as follows: in the face of bad weather conditions, first move the lifting frame 4 upward along the adjusting rod 3. At this time, the originally folded waterproof seal cover 5 will be gradually unfolded. When the lifting frame 4 reaches the specified height, then fix the lifting frame 4 on the adjusting rod 3 through the locking member 6. Finally, seal the top of the lifting frame 4 through the top cover 7. At this time, under the joint action of the surrounding waterproof seal cover 5 and the top cover 7, a relatively enclosed space can be provided for the circuit control box 2, effectively preventing the adverse effects brought by external rainwater to the internal circuit control box 2, creating conditions for the construction of the circuit control box 2 in bad weather conditions, further meeting the construction requirements, and improving the construction safety and stability.

[0034] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
