Description

Technical Field

[0001] This utility model belongs to the field of grouting technology, and more specifically, it relates to an adjustable grouting depth control guide frame. Background Technology

[0002] Grouting is a technique that involves injecting concrete grout into the soil through drilling. After solidification, the grout fills pores or fissures to enhance structural stability or prevent seepage. Once solidified, the grout forms a high-strength consolidated body with the soil, significantly improving the compressive strength and stability of the foundation. Currently, borehole grouting typically involves using a crane to lift multiple sets of interconnected grouting pipes into the borehole, and then a guide frame supports the top of the grouting pipes. Because the length of each set of grouting pipes is fixed and the guide frame supporting the grouting pipes lacks the function of compensating for the depth of the grouting pipes, when the grouting pipes are lowered to an insufficient depth, it is necessary to add spliced ​​grouting pipes at the top. However, adding spliced ​​pipes can lead to excessive lowering depths. Therefore, in traditional borehole grouting operations, the depth of the grouting pipes into the borehole is entirely determined by the length of the spliced ​​grouting pipes, resulting in the bottom of the multiple spliced ​​grouting pipes not accurately reaching the specified depth. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an adjustable grouting depth control guide frame, which solves the problem that in traditional grouting operations, the guide frame lacks a compensation and adjustment function for the depth position of the grouting conduit, causing the bottom of multiple sets of vertically spliced ​​grouting conduits to fail to accurately fall to the specified depth.

[0004] This utility model provides an adjustable grouting depth control guide frame, including a lifting ring frame; a support is welded to the bottom end of the lifting ring frame, and a control machine is installed on the outer side of the support; it also includes a lifting cylinder, an adjusting cylinder, and a guide rod; the outer side of the adjusting cylinder is rotatably connected to the support, and a lifting adjustment motor is installed on the outer side of the support. A transmission rod is installed on the motor shaft of the lifting adjustment motor, and a bevel gear is welded to the rear end of the transmission rod; a support ring plate is welded to the outer side of the lifting cylinder, a guide post is welded to the lower side of the support ring plate, and a lifting cylinder is welded to the bottom end of the guide post; a pressure cylinder is meshed with the outer side of the lifting cylinder; and a support block is slidably connected to the outer side of the guide rod.

[0005] Furthermore, the outer side of the lifting cylinder is provided with a threaded structure near the bottom and top. The outer side of the lifting cylinder is provided with four sets of rectangular through slots that are connected inside and out. The rectangular through slots are arranged in a circular array around the vertical central axis of the lifting cylinder. Support blocks are embedded in the rectangular through slots of the lifting cylinder, and grouting pipes are inserted into the inner side of the lifting cylinder.

[0006] Furthermore, the adjusting drum is a cylindrical structure that runs vertically through the body. The inner side of the adjusting drum is provided with a threaded structure. The inner side of the adjusting drum is threadedly connected to the outer side of the lifting drum near the bottom of the threaded structure. The outer side of the adjusting drum is surrounded by a helical tooth structure, and a bevel gear is engaged with the helical tooth structure of the adjusting drum.

[0007] Furthermore, the upper side of the support has a through hole at the center, and an adjusting cylinder is rotatably connected inside the center through hole of the support. The upper side of the support has four sets of protruding posts, and the center of the upper side of each set of protruding posts has a through hole structure, with guide posts inserted into the through holes of the protruding posts of the support.

[0008] Furthermore, the inner side of the pressure cylinder is provided with an inwardly protruding ring plate structure near the top position, and the inner side of the pressure cylinder ring plate structure is provided with a threaded structure. The threaded structure on the inner side of the pressure cylinder is engaged with the threaded structure on the outer side of the lifting cylinder near the top position, and a handrail frame is welded to the outer side of the pressure cylinder.

[0009] Furthermore, the number of support blocks is four sets. Each set of support blocks has an inclined structure on its upper side and a convex plate on its lower side. The convex plate of the support block has a through hole at its center. A guide rod is inserted into the through hole of the convex plate of the support block. A support ring plate is welded to the end of the guide rod. A tension spring is welded to the outer side of the support block. A support ring plate is welded to the other end of the tension spring.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this utility model, by adjusting the transmission adjustment mechanism composed of the rotating drum, bevel gear, and lifting adjustment motor, the lifting drum and the grouting pipe clamped inside can be driven to perform lifting compensation adjustment movements. This breaks through the limitation that the depth of the grouting pipe depends entirely on the length of the spliced ​​pipe, and avoids the situation where the lowering depth is too large or too small due to the fixed pipe length structure of the grouting pipe and the splicing. This allows the bottom of the grouting pipe to reach the specified grouting depth, greatly improving the accuracy of grouting depth control and ensuring the quality of grouting operations.

[0012] 2. In this utility model, the inclined structure of the support block is pushed by the bottom edge of the pressure cylinder to change the centripetal distance of the four sets of support blocks, so that the support blocks can clamp grouting pipes of various different diameters in the center. There is no need to equip the pipes of different diameters with special guide frames, which reduces the equipment procurement cost and inventory management difficulty. One set of guide frames can meet the clamping needs of diverse grouting pipes, and enhances the applicability of the guide frame to clamping grouting pipes of different diameters.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-7 As shown, this utility model provides an adjustable grouting depth control guide frame, including a lifting ring frame 2; a support 1 is welded to the bottom end of the lifting ring frame 2, and a control machine 7 is installed on the outer side of the support 1; it also includes a lifting cylinder 5, an adjusting rotating cylinder 11, and a guide rod 16; the support 1 is rotatably connected to the outer side of the adjusting rotating cylinder 11, a lifting adjusting motor 8 is installed on the outer side of the support 1, a transmission rod 9 is installed on the motor shaft of the lifting adjusting motor 8, and a bevel gear 10 is welded to the rear end of the transmission rod 9; a support ring plate 4 is welded to the outer side of the lifting cylinder 5, a guide post 3 is welded to the lower side of the support ring plate 4, the lifting cylinder 5 is welded to the bottom end of the guide post 3, and a pressure cylinder 14 is meshed with the outer side of the lifting cylinder 5; a support block 13 is slidably connected to the outer side of the guide rod 16.

[0023] In this embodiment of the present invention, the outer side of the lifting cylinder 5 is provided with threaded structures near the bottom and top ends. The outer side of the lifting cylinder 5 is provided with four sets of rectangular through slots that are connected internally and externally. The rectangular through slots are arranged in a circular array around the vertical central axis of the lifting cylinder 5. Support blocks 13 are embedded in the rectangular through slots of the lifting cylinder 5. Grouting conduits 12 are inserted into the inner side of the lifting cylinder 5. The walls of the rectangular through slots of the lifting cylinder 5, together with the guide rods 16, support the support blocks 13, ensuring that the four sets of support blocks 13 move horizontally and directionally along the walls of the rectangular through slots. This effectively avoids the support blocks 13 from shifting or tilting during movement, and allows the support blocks 13 to stably clamp the grouting conduits 12 inside the lifting cylinder 5 from all sides, ensuring that the grouting conduits 12 always remain vertical during the grouting operation, and improving the accuracy of grouting depth control.

[0024] In this embodiment of the utility model, the adjusting drum 11 is a cylindrical structure that runs vertically through the body. The inner side of the cylindrical structure of the adjusting drum 11 is provided with a threaded structure. The inner side of the adjusting drum 11 is threadedly connected to the outer side of the lifting drum 5 near the bottom of the threaded structure. The outer side of the cylindrical structure of the adjusting drum 11 is surrounded by a helical tooth structure. The bevel gear 10 is meshed with the helical tooth structure of the adjusting drum 11. During the process of the lifting and adjusting motor 8 driving the bevel gear 10 to rotate through the transmission rod 9, the bevel gear 10 drives the adjusting drum 11 to rotate through the helical tooth structure. The inner side of the adjusting drum 11 threadedly drives the lifting drum 5 to move up and down, so that the lifting drum 5 drives the grouting pipe 12 clamped on the inner side to perform lifting and compensating adjustment movements to adapt to different grouting depth requirements.

[0025] In this embodiment of the utility model, the upper side of the support 1 is provided with a through hole that runs vertically through the center. An adjusting cylinder 11 is rotatably connected in the central through hole of the support 1. The upper side of the support 1 is provided with four sets of protruding columns. The upper side of each set of protruding columns is provided with a through hole structure that runs vertically through the center. The guide column 3 is inserted into the through hole of the protruding column of the support 1. The through hole of the protruding column of the support 1 limits the horizontal rotation of the lifting cylinder 5 through the guide column 3, so as to prevent the adjusting cylinder 11 from forming a thread contact friction force through the inner thread of the lifting cylinder 5 and the outer thread of the lifting cylinder 5 to drive the lifting cylinder 5 to rotate horizontally, and ensure that the lifting cylinder 5 drives the grouting pipe 12 clamped inside to move stably up and down.

[0026] In this embodiment of the utility model, the inner side of the pressure cylinder 14 is provided with an inwardly protruding ring plate structure near the top. The inner side of the ring plate structure of the pressure cylinder 14 is provided with a threaded structure. The threaded structure of the inner side of the pressure cylinder 14 is engaged with the threaded structure of the outer side of the lifting cylinder 5 near the top. A handrail rotating frame 6 is welded to the outer side of the pressure cylinder 14. During the rotation of the pressure cylinder 14 driven by the handrail rotating frame 6, the pressure cylinder 14 rotates up and down along the threaded structure of the outer side of the lifting cylinder 5. When the pressure cylinder 14 moves downward, the bottom edge of the inner side of the pressure cylinder 14 pushes the inclined structure of the four sets of support blocks 13, so that the four sets of support blocks 13 move centripetally along the four sets of guide rods 16 and the four sets of rectangular through slots of the lifting cylinder 5, thereby completing the centripetal clamping work of the four sets of support blocks 13 on the grouting conduit 12.

[0027] In this embodiment of the utility model, there are four sets of support blocks 13. Each set of support blocks 13 has an inclined structure on its upper side and a convex plate on its lower side. The convex plate of the support block 13 has a through hole at its center. A guide rod 16 is inserted into the through hole of the convex plate of the support block 13. A support ring plate 4 is welded to the end of the guide rod 16. A tension spring 15 is welded to the outer side of the support block 13. The other end of the tension spring 15 is welded to the support ring plate 4. When the bottom edge of the inner side of the pressure cylinder 14 is separated from the inclined structure of the support block 13, the four sets of tension springs 15 drive the four sets of support blocks 13 to move centrifugally along the four sets of rectangular through slots of the lifting cylinder 5 through their own elastic tension, thereby completing the rapid and automatic release of the four sets of support blocks 13 to the grouting conduit 12.

[0028] Specific usage and function of this utility model embodiment:

[0029] When adjusting the grouting depth, the present invention first manually rotates the handrail frame 6, which drives the pressure cylinder 14 to rotate. Since the inner side of the pressure cylinder 14 is threadedly connected to the threaded structure near the top of the outer side of the lifting cylinder 5, the pressure cylinder 14 moves downwards at the threaded structure near the top of the outer side of the lifting cylinder 5. The bottom edge of the inner side of the pressure cylinder 14 contacts and presses the inclined structure of the four sets of support blocks 13. The four sets of support blocks 13 move centripetally along the four sets of guide rods 16. At this time, the four sets of support blocks 13 centripetally clamp and fix the grouting guide pipe 12. Then, the depth data to be compensated is input into the control machine 7, and the control machine 7 adjusts the depth accordingly. The lifting and adjusting motor 8, controlled by the compensation depth data, starts, which in turn drives the bevel gear 10, which is welded to the end of the transmission rod 9, to rotate. Since the bevel gear 10 is meshed with the helical tooth structure on the outer side of the adjusting cylinder 11, the bevel gear 10 drives the adjusting cylinder 11 to rotate. Since the inner side of the adjusting cylinder 11 is threadedly meshed with the thread structure near the bottom of the outer side of the lifting cylinder 5, the adjusting cylinder 11 drives the lifting cylinder 5 to move up and down along the through-hole structure of the guide rod 16 and the support 1 until the lifting cylinder 5 drives the grouting guide pipe 12 held on the inner side to penetrate to the specified grouting depth, thereby completing the compensation and adjustment of the grouting depth.

[0030] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies; any method that achieves the desired effect can be implemented. The control unit 7 and lifting and adjusting motor 8 mentioned above are common market components. Upon purchase and use, simply connect them according to the instruction manual provided; therefore, further details are omitted here.
