Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete pouring, and particularly relates to a concrete crack repair device. Background Art
[0002] During the long-term use of concrete roads, due to reasons such as construction quality, heavy vehicle rolling, and thermal expansion and contraction, some cracks will occur. To prevent the cracks from further expanding and the concrete roads from being further damaged, grouting repair materials such as epoxy resin and polyurethane are usually injected into the cracks to fill and repair the cracks, so as to extend the service life of the concrete roads.

However, when facing the repair work of long-distance and large-gap concrete cracks, due to the large and long gaps of the concrete cracks, a large amount of repair liquid will be consumed, so it is necessary to frequently replenish the repair liquid into the caulking gun, resulting in low work efficiency. In addition, when operating with a caulking gun, workers need to continuously maintain a bending or squatting posture, with a large labor intensity and inconvenient work.

[0031] Embodiment. This embodiment aims to provide a concrete crack repair device, and its main function is reflected in that in the repair operation scenario of large and long concrete cracks, it can effectively reduce the labor intensity of workers and significantly improve work efficiency.
[0032] Refer to Figure 1 and Figure 2 , which includes: a vehicle plate 1, a spiral extrusion cylinder 5 and a rotating shaft. Vertical plates 2 are fixedly provided at the four corners of the bottom surface of the vehicle plate 1. A pair of wheels 4 that rotate synchronously through a wheel shaft 3 are installed between two adjacent vertical plates 2 on both sides, front and rear. The end of the wheel shaft 3 is rotatably installed on the corresponding vertical plate 2. Among them, the front end of the left wheel shaft 3 protrudes outward from the vertical plate 2, and a driving pulley is fixedly sleeved on the outer part of the protruding part of the wheel shaft 3. A pair of columns 17 are fixedly provided on the right side of the top plate of the vehicle plate 1. The two columns 17 are distributed along the width direction of the vehicle plate 1, that is, arranged one in front and one behind. The upper ends of the two columns 17 are bent towards the right to form a handle for facilitating workers to push and pull the vehicle plate 1. The two columns 17 are connected by a connecting rod 18.
[0033] Refer to Figure 1 , Figure 2 and Figure 4 , the spiral extrusion cylinder 5 is vertically and fixedly inserted in the center of the vehicle plate 1. The bottom of the spiral extrusion cylinder 5 penetrates the vehicle plate 1 and is higher than the bottom of the wheel of the wheel 4 to prevent the bottom of the spiral extrusion cylinder 5 from rubbing against the ground and being damaged. The bottom of the spiral extrusion cylinder 5 is conical to reasonably control the discharge amount, and the discharge port is located at the bottom; storage hoppers 6 are fixedly provided above the left and right sides of the spiral extrusion cylinder 5. The discharge end at the bottom of the storage hopper 6 is communicated with the upper part of the barrel cavity of the spiral extrusion cylinder 5; a spiral shaft 501 is rotatably installed in the spiral extrusion cylinder 5. The upper end of the spiral shaft 501 protrudes outward from the top of the spiral extrusion cylinder 5 so as to fixedly sleeve a driven bevel gear 14 at the upper end of the spiral shaft 501.
[0034] Refer to Figure 1 、 Figure 2 and Figure 3 ,On the front and rear sides of the middle part of the top surface of the carriage plate 1, support rods 15 are vertically fixed. A rotating shaft is rotatably installed between the two support rods 15 so that the rotating shaft is horizontally placed above the spiral extrusion cylinder 5 along the width direction of the carriage plate 1. The front end of the rotating shaft protrudes outward from the front support rod 15. A driven pulley is fixedly sleeved outside the protruding part of the rotating shaft, and the driven pulley is connected to the driving pulley through a belt for synchronous rotation. Specifically, the rotating shaft includes: a thick shaft 7 and a thin shaft. The spiral shaft 501 of the spiral extrusion cylinder 5 rotates synchronously with the thick shaft 7. The head end of the thick shaft 7 is rotatably installed on the rear support rod 15, and a driving bevel gear 16 is fixedly sleeved outside the tail end, and the driving bevel gear 16 is engaged with the driven bevel gear 14. Thus, when the thick shaft 7 rotates, it can drive the spiral shaft 501 to rotate synchronously. The head end and the tail end of the thin shaft are both round shaft segments 8. The round shaft segment 8 at the head end of the thin shaft is rotatably nested in the tail end of the thick shaft 7. Among them, a bearing is sleeved outside the round shaft segment 8 at the head end of the thin shaft, and the bearing is embedded in the tail end of the thick shaft 7 and centered. The tail end of the thin shaft penetrates through the front support rod 15 and protrudes outward to fixedly sleeve a driven pulley, and the driven pulley is synchronously rotated with the driving pulley through a belt. When necessary, driven pulleys with different diameters can be replaced to adjust the rotation speed of the thin shaft.
[0035] A rectangular shaft segment 9 is provided at the middle part of the thin shaft closer to the head end, that is, the thick shaft 7. A slider 10 and a spring 11 are sleeved outside the rectangular shaft segment 9. Multiple insertion rods 12 protrude from the rear side of the slider 10 towards the thick shaft 7. Correspondingly, a plurality of insertion holes 13 for inserting the insertion rods 12 are provided on the end face of the tail end of the thick shaft 7. The spring 11 is located on the front side of the slider 10. Among them, the rectangular shaft segment 9 is thinner than the round shaft segment 8 to limit the spring 11. Based on this, by sliding the slider 10 forward, the insertion rods 12 on its rear side can be pulled out from the corresponding insertion holes 13. At the same time, the slider 10 will also squeeze the spring 11 on the front side to use the spring 11 to reset the slider 10. The reason for pulling out the insertion rods 12 from the insertion holes 13 is to prevent the thin shaft from driving the thick shaft 7 to rotate. Then, when the device is backing up, this effect can be used to prevent the spiral shaft 501 from reversing and causing the repair liquid in the spiral extrusion cylinder 5 to flow back.
[0036] In this embodiment, a linkage rod 19 is provided between the connecting rod 18 and the slider 10. The slider 10 is circular. The two ends of the linkage rod 19 are correspondingly sleeved outside the connecting rod 18 and the slider 10. Among them, an anti-friction bearing is nested between the slider 10 and the end of the linkage rod 19 to prevent the linkage rod 19 from hindering the rotation of the slider 10. The anti-friction bearing is not shown in the figure, and its function is the same as that of the bearing described above. Through the linkage rod 19, it is convenient for workers to manipulate the slider 10 at a distance, and the operation is smoother.
[0037] During actual use, just move this device along the concrete crack, and the repair liquid will be extruded from the bottom of the spiral material extrusion cylinder 5 and injected into the gap below. During this period, if it is found that the gap is not filled with the repair liquid, the device can be moved backward along the crack, provided that the insertion rod 12 behind the slider 10 is pulled out from the insertion hole 13 to prevent the repair liquid from flowing back due to the reverse rotation of the spiral shaft 501. After moving backward to the designated position, release the slider 10. At this time, the head end of the insertion rod 12 may not be exactly corresponding to the insertion hole 13, but against the tail end of the thick shaft 7. Just gently and slowly push the device forward to change the position of the insertion rod 12. When the insertion rod 12 corresponds to the insertion hole 13, it will automatically insert by using the reaction force of the spring 11. Next, the repair liquid will be normally extruded from the bottom of the spiral material extrusion cylinder 5.
[0038] The repair device provided in this embodiment is mainly aimed at the repair operation of concrete cracks with large and long gaps. In this scenario, it can effectively reduce the labor intensity of workers and significantly improve work efficiency.
[0039] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.
[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of the claims of the present invention awaiting approval.
