Description

Technical Field

[0001] This utility model relates to the field of pole crack repair technology, and more specifically, to a grouting guide device for repairing cracks in recycled concrete poles. Background Technology

[0002] Recycled concrete poles are power support structures made of recycled concrete materials, mainly used in the construction of power transmission lines and communication facilities. However, during long-term use, recycled concrete poles are prone to surface cracks due to the influence of the natural environment, external loads, and the inherent properties of the material. In order to improve the service life and safety of the poles, grouting is required to repair the cracks.

[0003] However, currently, there is a lack of dedicated grouting guide structures when performing grouting repairs. The grouting head often relies on the operator's hand-held positioning. When the crack direction is irregular, it is difficult to ensure that the grouting head always accurately follows the crack trajectory, which easily leads to grouting omissions and material waste, resulting in poor repair effects. In view of this, this utility model proposes a grouting guide device for repairing cracks in recycled concrete poles. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a grouting guide device for repairing cracks in recycled concrete poles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grouting guide device for repairing cracks in recycled concrete poles, comprising a grouting tank, a high-pressure pump being provided on one side of the grouting tank, a connecting pipe and a delivery hose being connected to the input and output ends of the high-pressure pump respectively, and a grouting head being provided at one end of the delivery hose.

[0006] As can be seen, the structure stores repair materials in a grouting tank, provides power with a high-pressure pump, uses connecting pipes and delivery hoses to form a transmission path, and finally delivers the repair materials to the cracks in the pole through the grouting head.

[0007] Preferably, a grouting auxiliary structure is installed at the grouting head. The grouting auxiliary structure includes a sleeve rod located on one side of the grouting tank. A telescopic rod is slidably installed inside the sleeve rod. One end of the telescopic rod is provided with an arc-shaped plate. The end of the telescopic rod is bent and fixedly installed on the outer wall of the arc-shaped plate. An installation cylinder is fixedly embedded in the center of the surface of the arc-shaped plate. The grouting head is installed inside the installation cylinder through a clamping assembly. L-shaped rods are fixedly installed at the top and bottom of the arc-shaped plate. One end of the L-shaped rod is provided with a ball seat. A universal positioning ball is rolled inside the ball seat.

[0008] To achieve stable installation and flexible adjustment of the grouting head, this structure can adapt to different repair heights of the pole cracks by sliding the telescopic rod within the sleeve, and can also drive the grouting head to follow precisely by rolling the universal positioning ball along the crack direction, thereby meeting the grouting guidance requirements of irregular cracks.

[0009] Preferably, an installation ring is fixedly installed on the surface of the grouting tank, and a sealing cover is detachably installed on the installation ring by bolts. Two handles are welded on the sealing cover, and a stirring motor is fixedly installed on the sealing cover. A stirring shaft is fixedly installed on the output end of the stirring motor, and stirring blades are installed on the stirring shaft. Both the stirring shaft and the stirring blades are located inside the grouting tank.

[0010] This structure is designed to agitate the grouting material inside the tank by driving the agitator shaft and agitator blades with an agitator motor to prevent coagulation, while also facilitating subsequent rinsing and cleaning of the inside of the grouting tank and the agitator components.

[0011] Preferably, the sleeve rod is connected to an internal threaded sleeve, the internal thread of the internal threaded sleeve is engaged with a positioning screw, the outer wall of the telescopic rod is provided with a plurality of threaded holes, the positioning screw is threadedly connected to the threaded holes, and the outside of the sleeve rod is provided with an anti-slip rubber sleeve.

[0012] This structure is designed to securely limit the sliding adjustment of the telescopic pole, facilitating the repair of cracks at different heights on the pole.

[0013] Preferably, the clamping assembly includes clamping plates symmetrically distributed inside the mounting cylinder, an adjusting screw is mounted on the clamping plate, the adjusting screw is threadedly connected to the mounting cylinder, and the grouting head is clamped between the two clamping plates, with one end extending to the outside of the mounting cylinder.

[0014] This structure is designed to ensure the grouting head is securely installed and easily disassembled within the mounting cylinder, facilitating subsequent grouting guidance operations.

[0015] The technical effects and advantages of this utility model are as follows: 1. By setting up an auxiliary grouting structure, the height of the arc plate can be adjusted by sliding the telescopic rod inside the sleeve to adapt to different crack locations. With the help of the universal positioning ball rolling along the crack direction, the grouting head can be moved accurately. This effectively solves the problem of difficult grouting guidance for irregular cracks, greatly improving the accuracy and efficiency of crack repair. At the same time, the clamping component enables the grouting head to be stably installed and easily disassembled, reducing the difficulty of operation. 2. By installing a detachable sealing cover with a stirring motor, stirring shaft, and stirring blades on the grouting tank, the grouting material can be continuously stirred to prevent coagulation and ensure stable performance. The sealing cover can also be easily removed to clean the inside of the grouting tank and the stirring components, extending the service life of the device. Furthermore, the positioning screw and anti-slip rubber sleeve design on the extension rod ensures the stability of the telescopic rod after adjustment and improves the comfort and safety of the operator when holding it, further optimizing the user experience of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1-6The grouting guide device for repairing cracks in recycled concrete poles shown includes a grouting tank 1, a high-pressure pump 2 on one side of the grouting tank 1, a connecting pipe 3 and a delivery hose 4 connected to the input and output ends of the high-pressure pump 2 respectively, and a grouting head 5 is provided at one end of the delivery hose 4.

[0025] Specifically, in this structure, when cracks appear on the surface of the recycled concrete pole and need to be repaired, the repair material inside the grouting tank 1 can be transported through the connecting pipe 3 and the delivery hose 4 by the high-pressure pump 2, and finally injected into the crack through the grouting head 5 for repair.

[0026] In this embodiment, as shown in the appendix Figure 1 , 3 As shown in Figure 4, a grouting auxiliary structure is installed at the grouting head 5. The grouting auxiliary structure includes a sleeve rod 6, which is located on one side of the grouting tank 1. A telescopic rod 7 is slidably installed inside the sleeve rod 6. An arc-shaped plate 8 is provided at one end of the telescopic rod 7. The end of the telescopic rod 7 is bent and fixedly installed on the outer wall of the arc-shaped plate 8. An installation cylinder 9 is fixedly embedded in the center of the surface of the arc-shaped plate 8. The grouting head 5 is installed inside the installation cylinder 9 through a clamping assembly. L-shaped rods 10 are fixedly installed at the top and bottom of the arc-shaped plate 8. A ball seat 11 is provided at one end of the L-shaped rod 10. A universal positioning ball 12 is rolled inside the ball seat 11.

[0027] Specifically, when guiding the grouting during the repair of cracks in utility poles, the grouting head 5, which is connected to one end of the delivery hose 4, is installed inside the mounting cylinder 9 and fixed by the clamping assembly; The operator slides the telescopic rod 7 inside the sleeve rod 6 to adjust the arc plate 8 according to the required repair height of the pole. Holding the sleeve rod 6, the operator attaches the arc plate 8 to the arc-shaped outer wall of the pole. At this time, the universal positioning ball 12 is attached to the crack of the pole, while the grouting head 5 extends into the inside of the crack. The operator uses the lever operation device to make the universal positioning ball 12 roll omnidirectionally inside the ball seat 11. The universal positioning ball 12 rolls along the direction of the crack on the pole. At the same time, the grouting head 5 also follows the rolling direction of the universal positioning ball 12 to inject grouting material into the crack, thus achieving grouting guidance operation. This is applicable to the repair guidance operation of cracks with irregular directions.

[0028] In this embodiment, as shown in the appendix Figure 1 , 2As shown, an installation ring 13 is fixedly installed on the surface of the grouting tank 1. A sealing cover 14 is detachably installed on the installation ring 13 by bolts. Two handles 15 are welded on the sealing cover 14. A stirring motor 16 is fixedly installed on the sealing cover 14, and a stirring shaft 17 is fixedly installed on the output end of the stirring motor 16. A stirring blade 18 is installed on the stirring shaft 17. Both the stirring shaft 17 and the stirring blade 18 are inside the grouting tank 1.

[0029] Specifically, in this structure, the grouting repair material is poured into the grouting tank 1, and the stirring shaft 17 and stirring blade 18 are located inside the grouting tank 1. At this time, the sealing cover 14 is attached to the surface of the mounting ring 13 and fixed by bolts. At this time, the stirring motor 16 drives the stirring shaft 17 and stirring blade 18 to rotate inside the grouting tank 1 to stir the grouting material and prevent coagulation. After the grouting material is used up, remove the bolts and lift the sealing cover 14 using the two handles 15, so that the stirring shaft 17 and stirring blade 18 can be separated from the inside of the grouting tank 1, making it easy to flush the inside of the grouting tank 1 or to flush the stirring shaft 17 and stirring blade 18.

[0030] In this embodiment, as shown in the appendix Figure 1 , 3 As shown in Figure 6, the sleeve rod 6 is connected to an internal threaded sleeve 19, and the internal thread of the internal threaded sleeve 19 is fitted with a positioning screw 20. The outer wall of the telescopic rod 7 is provided with several threaded holes 21, and the positioning screw 20 is threadedly connected to the threaded holes 21. The sleeve rod 6 is provided with an anti-slip rubber sleeve 22.

[0031] Specifically, in this structure, after the telescopic rod 7 slides and adjusts inside the sleeve rod 6, the threaded hole 21 at the telescopic rod 7 corresponds to the internal threaded sleeve 19 at the sleeve rod 6. Through the threaded engagement of the positioning screw 20 with the internal threaded sleeve 19, the positioning screw 20 extends into the interior of the threaded hole 21, thereby thread-limiting the adjusted telescopic rod 7.

[0032] In this embodiment, as shown in the appendix Figure 5 As shown, the clamping assembly includes clamping plates 23 symmetrically distributed inside the mounting cylinder 9. An adjusting screw 24 is installed on the clamping plate 23 and is threadedly connected to the mounting cylinder 9. The grouting head 5 is clamped between the two clamping plates 23 and one end extends to the outside of the mounting cylinder 9.

[0033] Specifically, in this structure, after the grouting head 5 is installed inside the mounting cylinder 9, the two clamping plates 23 are clamped by rotating the corresponding adjusting screw 24, so that the grouting head 5 can be detachably installed inside the mounting cylinder 9, which facilitates subsequent grouting guidance operations.

[0034] Working principle of this utility model: This application provides a grouting guide device for repairing cracks in recycled concrete poles. In specific use, the grouting repair material is first poured into the grouting tank 1. Then, the sealing cover 14 is attached to the mounting ring 13 on the surface of the grouting tank 1, and the sealing cover 14 is fixedly installed by bolts. At this time, the stirring shaft 17 and the stirring blade 18 are both inside the grouting tank 1. The stirring motor 16 is started, which drives the stirring shaft 17 to drive the stirring blade 18 to rotate inside the grouting tank 1, continuously stirring the grouting material to prevent the material from solidifying. Place the grouting head 5, which is connected to one end of the delivery hose 4, into the interior of the mounting cylinder 9. Then rotate the adjusting screw 24 on the mounting cylinder 9. Since the adjusting screw 24 is threadedly connected to the mounting cylinder 9, when it is rotated, it will push the symmetrically distributed clamping plates 23 toward the grouting head 5 until the two clamping plates 23 firmly clamp the grouting head 5, thereby realizing the detachable and fixed grouting head 5 in the mounting cylinder 9, and preparing for grouting guidance. Based on the height required to repair the cracks in the recycled concrete pole, the operator holds the anti-slip rubber sleeve 22 on the outside of the sleeve 6 and pushes the telescopic rod 7 to slide inside the sleeve 6. When the arc plate 8 reaches the appropriate height, the threaded hole 21 on the outer wall of the telescopic rod 7 is aligned with the internal threaded sleeve 19 connected to the sleeve 6. Then, the positioning screw 20 is screwed into the internal threaded sleeve 19 and threadedly connected to the threaded hole 21 to limit and fix the adjusted telescopic rod 7, ensuring that the height of the device meets the grouting requirements. The operator holds the sleeve rod 6 and attaches the arc plate 8 to the arc-shaped outer wall of the pole, ensuring that the universal positioning ball 12 in the ball seat 11 is attached to the crack in the pole. At the same time, the grouting head 5 extends into the crack. The high-pressure pump 2 is started, and the repair material in the grouting tank 1 is delivered to the grouting head 5 through the connecting pipe 3 and the delivery hose 4. The operator uses the control device to make the universal positioning ball 12 roll omnidirectionally in the ball seat 11 along the crack direction. The grouting head 5 moves synchronously with the rolling trajectory of the universal positioning ball 12, accurately injecting the grouting material into the crack, thus completing the repair guidance operation for the irregular crack. After the grouting material is used up, remove the bolts connecting the sealing cover 14 and the mounting ring 13, lift the sealing cover 14 using the two handles 15 on the sealing cover 14, so that the stirring shaft 17 and stirring blade 18 can be separated from the grouting tank 1. Then the inside of the grouting tank 1 can be rinsed, and the stirring shaft 17 and stirring blade 18 can also be cleaned for the next use of the device.
