Description

Technical Field

[0001] This application relates to the field of road repair technology, and in particular to a field grouting device for road repair. Background Technology

[0002] Road surfaces may develop defects such as cracks due to external factors such as high temperatures, rain, and cold winters. Emergency repairs of these cracks are usually carried out using grouting. During grouting, a grouting pipe is first inserted into the crack, and then an automatic grouting device is used to inject grouting material into the grouting pipe, allowing the grouting material to penetrate into the crack and repair it.

[0003] Currently, grouting devices have the following problems: on the one hand, there is a lack of effective vertical positioning when inserting grouting pipes, which makes the grouting pipes prone to tilting; on the other hand, different cracks have different depths, making it difficult to prepare grouting pipes of appropriate length on site and insert them into the appropriate depth of the cracks.

[0004] Therefore, there is a need for a field grouting device for road repair that can vertically position the grouting conduit and adjust the insertion depth. Utility Model Content

[0005] Therefore, it is necessary to provide a field grouting device for road emergency repair, and its specific technical solution is as follows.

[0006] A road surface emergency repair on-site grouting device includes: Frame; The grouting machine body is mounted on the vehicle frame and is connected to the grouting gun; The grouting conduit is connected to the grouting gun; the grouting conduit includes multiple sub-pipes connected end to end in sequence; the sub-pipes are provided with limiting grooves on their walls; The positioning assembly includes a positioning tube and a locking assembly. The positioning tube is mounted on the frame, with one end extending into the crack. The positioning tube has an installation groove, and the grouting conduit is inserted into the positioning tube. The locking assembly includes a positioning ball and a limiting sleeve. The positioning ball is movably disposed in the installation groove in the radial direction, and the limiting sleeve is movably fitted inside the positioning tube in the axial direction. When the limiting sleeve moves to the point where its inner wall abuts against the positioning ball, it squeezes the positioning ball into the limiting groove.

[0007] Furthermore, the positioning tube includes a first tube body and a second tube body; a stepped portion is formed between the first tube body and the second tube body; when the limiting sleeve moves to abut against the stepped portion, the inner wall of the limiting sleeve abuts against the positioning ball.

[0008] Furthermore, the end of the limiting sleeve is provided with insert teeth; the stepped portion is provided with spaced protrusions, and a slot for accommodating the insertion of insert teeth is formed between adjacent protrusions; the mounting groove is provided at the slot.

[0009] Furthermore, the limiting sleeve is movably sleeved on the first tube body along the axial direction, and a threaded sleeve is also threadedly sleeved on the first tube body; the threaded sleeve is located above the limiting sleeve.

[0010] Furthermore, the frame is provided with a positioning hole; a baffle is threaded onto the second tube; the second tube is inserted into the positioning hole, and the baffle abuts against the frame.

[0011] Furthermore, the sub-tube body is provided with a marking line, so that when the marking line is aligned with the top of the positioning tube, the limiting slot is aligned with the mounting slot.

[0012] Furthermore, the sub-tube body has a first connecting part at one end and a second connecting part at the other end; the first connecting part has a threaded section and a shielding section; the limiting groove is disposed on the second connecting part; the first connecting part is inserted into the second connecting part, so that the threaded section is connected to the second connecting part, and the shielding section blocks the limiting groove.

[0013] Furthermore, the length of the limiting groove is greater than the diameter of the positioning ball.

[0014] Beneficial effects: The on-site grouting device for road emergency repair provided by this utility model can assemble grouting pipes of appropriate length according to the depth of the crack by splicing sub-pipes, so that the grouting pipes can be inserted to a suitable depth to ensure the grouting effect on the crack; during and after the insertion of the grouting pipes into the crack, the positioning pipes can be vertically positioned by the positioning pipes to prevent the grouting pipes from tilting and ensure the grouting quality; and the locking component can vertically position or unlock the grouting pipes and the positioning pipes. In the vertically positioned state, the grouting pipes can be kept stable, which is convenient for splicing sub-pipes. In the unlocked state, the grouting pipes can be moved relative to the positioning pipes, which is convenient for the grouting pipes to continue to penetrate deeper into the crack.

[0024] Example Reference Figure 1 As shown, this embodiment provides an on-site grouting device for road repair, including a frame 310, a grouting body 320, a grouting conduit 330, and a positioning component 340. The frame 310 has casters at its bottom and a push rod on its surface, facilitating the movement of the grouting device to a designated location by construction personnel for grouting cracks. The grouting body 320 is mounted on the frame 310 and connected to a grouting gun 321. Grouting material is stored within the grouting body 320, and grout is injected into the grouting conduit 330 via the grouting gun 321. The specific structure of the grouting body 320 and how to use the grouting gun 321 for grouting can be found in existing technology and are not limited in this embodiment.

[0025] Specifically, refer to Figure 1 and Figure 3As shown, the grouting conduit 330 is connected to the grouting gun 321. Grout is injected into the grouting conduit 330 through the grouting gun 321, thereby injecting the grout into the crack. The grouting conduit 330 includes multiple sub-pipes 331 connected end-to-end in sequence. During grouting operations, the appropriate number of sub-pipes 331 can be selected for on-site assembly according to the depth of the crack. Each sub-pipe 331 is provided with a limiting groove 332.

[0026] Reference Figure 2 As shown, the positioning assembly 340 includes a positioning tube 341 and a locking assembly. The positioning tube 341 is mounted on the frame 310, with one end extending into the crack. The positioning tube 341 has a mounting groove 3411. The grouting conduit 330 is inserted into the positioning tube 341, and the positioning tube 341 vertically positions the grouting conduit 330, preventing it from tilting during insertion into the crack and subsequent grouting operations, thus ensuring the final grouting quality. (Refer to...) Figure 4 As shown, the locking assembly includes a positioning ball 342 and a limiting sleeve 343. The positioning ball 342 is movably disposed within the mounting groove 3411 in the radial direction, and the limiting sleeve 343 is movably fitted within the positioning tube 341 in the axial direction. When the limiting sleeve 343 moves to the point where its inner wall abuts against the positioning ball 342, it compresses the positioning ball 342 and engages it within the limiting slot 332. By moving the limiting sleeve 343, the locking and unlocking states between the positioning tube 341 and the grouting conduit 330 can be switched. In the locked state, the position of the grouting conduit 330 can be restricted, facilitating the installation of the sub-tube 331. In the unlocked state, the grouting conduit 330 can continue to penetrate deeper into the crack. It should be noted that the diameter of the groove openings at both ends of the mounting groove 3411 is smaller than the diameter of the positioning ball 342 to prevent the positioning ball 342 from detaching from the mounting groove 3411.

[0027] The on-site grouting device for road repair provided in this embodiment can assemble grouting conduits 330 of appropriate length according to the depth of the crack by splicing sub-pipe bodies 331, so that the grouting conduits 330 can be inserted to a suitable depth to ensure the grouting effect on the crack. During and after the insertion of the grouting conduits 330 into the crack, the positioning tube 341 can be used to vertically position the grouting conduits 330 to prevent the grouting conduits 330 from tilting and to ensure the grouting quality. Furthermore, the locking component can vertically position or unlock the grouting conduits 330 and the positioning tube 341. In the vertically positioned state, the grouting conduits 330 can be kept stable, which facilitates the splicing of sub-pipe bodies 331. In the unlocked state, the grouting conduits 330 can be moved relative to the positioning tube 341, which facilitates the grouting conduits to continue to penetrate deeper into the crack.

[0028] Specifically, refer to Figure 2As shown, the positioning tube 341 includes a first tube body 3412 and a second tube body 3413; a stepped portion 3414 is formed between the first tube body 3412 and the second tube body 3413; when the limiting sleeve 343 moves to abut against the stepped portion 3414, the inner wall of the limiting sleeve 343 abuts against the positioning ball 342. Under the action of gravity, the limiting sleeve 343 remains abutting against the stepped portion 3414, thereby keeping the positioning tube 341 and the grouting conduit 330 locked.

[0029] Specifically, the end of the limiting sleeve 343 is provided with insert teeth 3431; the stepped portion 3414 is provided with spaced protrusions 3415, and a slot 3416 is formed between adjacent protrusions 3415 to accommodate the insertion of the insert teeth 3431; the mounting groove 3411 is provided at the slot 3416. When the grouting conduit 330 continues to penetrate into the crack, the limiting sleeve 343 can be moved until the insert teeth 3431 disengage from the tooth groove, and the limiting sleeve 343 can be rotated so that the insert teeth 3431 abut against the protrusions 3415. This keeps the grouting conduit 330 and the positioning tube 341 in an unlocked state, so that the limiting sleeve 343 does not need to be held all the time; correspondingly, when locking is required, the limiting sleeve 343 can be rotated again so that the insert teeth 3431 align with the slot 3416 and insert the insert teeth 3431 into the slot 3416.

[0030] Specifically, the limiting sleeve 343 is movably fitted onto the first pipe body 3412 along the axial direction, and a threaded sleeve 344 is also threaded onto the first pipe body 3412; the threaded sleeve 344 is located above the limiting sleeve 343. During the assembly of the sub-pipe body 331 and the continuous penetration of the grouting conduit 330 into the crack, the position of the threaded sleeve 344 can be kept constant, reserving space for the vertical movement of the limiting sleeve 343; in subsequent grouting operations, when the limiting sleeve 343 moves to abut against the stepped portion 3414, the threaded sleeve 344 can be screwed downwards to keep the threaded sleeve 344 abutting against the limiting sleeve 343, ensuring the reliability of the locking between the positioning pipe 341 and the grouting conduit 330, thereby maintaining the stability of the grouting conduit 330.

[0031] Specifically, the frame 310 is provided with a positioning hole; a baffle 345 is threaded onto the second tube; the second tube is inserted into the positioning hole, and the baffle 345 abuts against the frame 310. By adjusting the position of the baffle 345, the length of the positioning tube 341 protruding from the frame 310 can be changed, and the vertical position of the grouting conduit 330 can be limited by the positioning tube 341, thereby adjusting the insertion depth of the grouting conduit 330. It should be noted that the baffle 345 can also be bolted to the frame 310 to maintain the stability of the positioning tube 341.

[0032] Specifically, the sub-tube body 331 is provided with a marking line, so that when the marking line is aligned with the top of the positioning tube 341, the limiting groove 332 is aligned with the mounting groove 3411. During locking, the marking line can be used to ensure that the limiting groove 332 is aligned with the mounting groove 3411, thereby ensuring that the positioning ball 342 is smoothly inserted into the limiting groove 332.

[0033] Specifically, the length of the limiting groove 332 is greater than the diameter of the positioning ball 342. Precise positioning of the limiting groove 332 and the positioning ball 342 is not required in the circumferential direction, reducing the difficulty of operation.

[0034] Specifically, the sub-tube body 331 has a first connecting part 333 at one end and a second connecting part 334 at the other end; the first connecting part 333 has a threaded section and a shielding section; the limiting groove 332 is disposed on the second connecting part 334; the first connecting part 333 is inserted into the second connecting part 334, so that the threaded section is connected to the second connecting part 334, and the shielding section blocks the limiting groove 332. The shielding section can block the limiting slot 332 to prevent slurry leakage. When assembling the sub-tube body 331, the positioning ball 342 can rotate and limit the installed sub-tube body 331, making it easier to tighten another sub-tube body 331 to the installed sub-tube body 331. It should be noted that when the installed sub-tube body 331 is rotated in the tightening direction until the positioning ball 342 abuts against the end of the limiting slot 332, the sub-tube body 331 cannot continue to rotate in the tightening direction under the restriction of the positioning ball 342, thus facilitating the tightening of the next sub-tube body 331.

[0035] Installation process: Move the grouting device to the crack location, determine the insertion depth of the grouting conduit 330 based on the crack depth, then adjust the baffle 345 and insert the positioning tube 341 into the positioning hole of the frame 310, determining the exposed length of the positioning tube 341; insert the sub-tube body 331 into the positioning tube 341, assemble the next sub-tube body 331 in the locked state, and continue moving the grouting conduit 330 downwards in the unlocked state until the grouting conduit 330 reaches the preset depth, then connect the grouting gun 321 to the grouting conduit 330. It should be noted that the specific correspondence between the crack depth and the insertion depth of the grouting conduit 330 is not an improvement point of this application, and therefore will not be elaborated upon.

[0036] Locking process: When the sub-tube body 331 moves to the point where the indicator line is aligned with the top of the positioning tube 341, rotate the limiting sleeve 343 until the insertion tooth 3431 is aligned with the slot 3416, move the limiting sleeve 343 downward to squeeze the positioning ball 342, so that the positioning ball 342 is inserted into the limiting slot 332; Unlocking process: move the limiting sleeve 343 upward until the insertion tooth 3431 disengages from the slot 3416, rotate the limiting sleeve 343 so that the insertion tooth 3431 falls on the protrusion 3415, and remain in the unlocked state.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
