[0019] ​​In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0020] In the description of the utility model, it should be pointed out that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the utility model product is used, which is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0021] As Figures 1 to 4 shown, it is a sleeve device for repairing concrete pile head provided by the utility model embodiment. The sleeve device for repairing concrete pile head comprises a base plate 1, a driving assembly 3, a plurality of telescopic supporting columns 4 and a plurality of arc-shaped templates 5 with elasticity; preferably, the material of the arc-shaped template 5 is alloy steel with elastic properties, and a plurality of arc-shaped templates 5 are connected end to end to form a sleeve 6 for sleeving the concrete pile head, and the sleeve 6 is located in the middle of the base plate 1. The plurality of telescopic supporting columns 4 are connected one by one with the plurality of arc-shaped templates, the telescopic supporting column 4 is slidably installed on the base plate 1 along the radial direction of the base plate 1, and the plurality of telescopic supporting columns 4 are evenly arranged on the base plate 1 along the circumferential direction of the base plate 1; the driving assembly 3 is installed on the base plate 1 and is in transmission connection with the telescopic supporting column 4 to simultaneously drive the plurality of telescopic supporting columns 4 to move along the radial direction of the base plate 1, thereby being able to drive the arc-shaped template 5 to move and change the caliber size of the sleeve 6.

[0022] Specifically, the arc-shaped template 5 comprises a body part 51 and a first lap joint part 52 and a second lap joint part 53 connected to both ends of the body part 51, the body part 51 is connected to one end of the telescopic supporting column 4, the first lap joint part 52 is lapped on the second lap joint part 53 between the adjacent two arc-shaped templates 5, and the second lap joint part 53 can abut on the first lap joint part 52 to make the inner side of the second lap joint part 53 and the outer side of the first lap joint part 52 mutually fit by overcoming the elastic force of the first lap joint part 52. When the driving assembly 3 drives the plurality of telescopic supporting columns 4 to move simultaneously, the plurality of arc-shaped templates 5 are driven to move simultaneously, the first lap joint part 52 and the second lap joint part 53 move relatively, and the arc-shaped template 5 changes the arc to change the caliber size of the sleeve 6.

[0023] When the diameter of the sleeve 6 needs to be increased, the telescopic support column 4 is driven to move outward along the radial direction of the base 11 by the drive assembly 3, so as to move the arc-shaped template 5 outward. The first overlapping part 52 elastically deforms towards the side closer to the second overlapping part 53 and always abuts against the second overlapping part 53, so as to increase the curvature of the first overlapping part 52, thereby increasing the diameter of the sleeve 6 formed by the overlapping of several arc-shaped templates 5. When the diameter of the sleeve 6 needs to be reduced, the telescopic support column 4 is driven to move inward along the radial direction of the base 11 by the drive assembly 3, so as to move the arc-shaped template 5 inward. The first overlapping part 52 elastically deforms towards the side away from the second overlapping part 53 under the abutment of the second overlapping part 53, so as to reduce the curvature of the first overlapping part 52, thereby reducing the diameter of the sleeve 6 formed by the overlapping of several arc-shaped templates 5. This allows for flexible adjustment and adaptation to concrete pile heads of different specifications and sizes.

[0024] In some embodiments, the thickness of the first overlapping portion 52 gradually decreases from the end near the body portion 51 toward the end away from the body portion 51, and the thickness of the second overlapping portion 53 gradually decreases from the end near the body portion 51 toward the end away from the body portion 51. The thickness of the second overlapping portion 53 is greater than the thickness of the first overlapping portion 52, so that the hardness of the second overlapping portion 53 is greater than the hardness of the first overlapping portion 52. Thus, when the driving assembly 3 drives the telescopic support column 4 to move the arc-shaped template 5 inward along the radial direction of the chassis 1, the first overlapping portion 52 can be easily elastically deformed toward the side away from the second overlapping portion 53 after the second overlapping portion 53 abuts against the first overlapping portion 52.

[0025] In some embodiments, the drive assembly 3 includes a ring gear 31 and a transmission gear 32, both of which are rotatably mounted on the chassis 1. The ring gear 31 and the transmission gear 32 mesh with each other. The telescopic support column 4 has a rack 41, and the transmission gear 32 meshes with the rack 41. Rotation of the ring gear 31 drives the transmission gear 32 to rotate, which in turn drives the telescopic support column 4 to move linearly.

[0026] Specifically, the chassis 1 includes a base 11 and a fixing ring 22. The fixing ring 22 is connected to the base 11. The telescopic support column 4 is disposed between the base 11 and the fixing ring 22 and is slidably mounted on the fixing ring 22. Preferably, a groove 221 is provided on the fixing ring 22, and a protrusion 42 is provided on the telescopic support column 4. The protrusion 42 is slidably mounted in the groove 221. The cross-sections of both the groove 221 and the protrusion 42 are trapezoidal. The groove 221 and the protrusion 42 cooperate with each other to not only provide support for the telescopic support column 4 and enhance its stability during device operation, but also effectively avoid swaying or displacement caused by unstable support. The ring gear 31 is rotatably fitted inside the fixing ring 22. The gear ring of the ring gear 31 protrudes from the inner ring of the fixing ring 22. This ingenious design allows the ring gear 31 to rotate freely within the fixing ring 22 and to efficiently transmit power through close meshing with the transmission gear 32. The inner side of the fixing ring 22 is provided with a support ring 23 for supporting the telescopic support column 4 to ensure the stability of the telescopic support column 4 during movement.

[0027] In some embodiments, the base 11 is provided with a plurality of positioning members 111 distributed along the circumferential direction of the base 11, and the ring gear 31 is provided with an operating handle 7 for controlling the rotation of the ring gear 31. The operating handle 7 can rotate relative to the ring gear 31. By rotating the operating handle 7 relative to the ring gear 31 to be approximately perpendicular to the ring gear 31, pushing or pulling the operating handle 7 can drive the ring gear 31 to rotate within the chassis 1, thereby driving the telescopic support column 4 to extend and retract.

[0028] In some embodiments, a limiting groove 112 is formed between two adjacent positioning members 111 to restrict the movement of the operating handle 7, and the operating handle 7 can be rotatably inserted into the limiting groove 112. Specifically, a notch 222 is provided on the periphery of the fixing ring 22, the positioning member 111 is disposed in the notch 222, and the operating handle 7 can be inserted into the limiting groove 112 through the notch 222. In this way, the operator can hold the operating handle 7 and rotate it away from the limiting groove 112, and push the operating handle 7 according to the actual repair needs of concrete pile heads of different sizes and specifications to drive the ring gear 31 to rotate, thereby driving the telescopic support column 4 to move and adjust the diameter of the sleeve 6 to match the size of the concrete pile head. Then, the operating handle 7 is rotated and inserted into the limiting groove 112 to restrict the position of the operating handle 7, thereby fixing the operating handle 7 in different positions to meet the diverse operational needs when dealing with concrete pile heads of various diameters during the concrete pile head repair process.

[0029] In summary, this utility model constructs a sleeve 6 for fitting concrete pile heads by connecting several elastic arc-shaped templates 5 end to end. The drive assembly 3 drives the telescopic support column 4 to move along the radial direction of the base plate 1, thereby moving the arc-shaped templates 5. After the first overlapping part 52 and the second overlapping part 53 move relative to each other, the arc-shaped templates 5 can undergo elastic deformation to change the diameter of the sleeve 6. This allows for flexible adjustment and adaptation to pile heads of different specifications and sizes, making the operation convenient.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
