Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This application provides a cement pole centrifuge mold connection structure that allows for quick bushing replacement, solving the problems of long bushing replacement time and troublesome hole alignment in existing systems.

[0024] By setting up fixed components, the traditional multiple steps of hoisting, manual adjustment, hole alignment, and fastening are simplified to hoisting, positioning, and fastening, which shortens the bushing replacement time, enables the bushing to be quickly positioned and aligned with the mold, improves replacement efficiency, and reduces the labor intensity and skill requirements of the staff.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cement pole centrifuge mold connection structure with quick-change bushings includes: a lower mold 1, an upper mold 101 mounted on the top of the lower mold 1, a lower bushing 2 inside the lower mold 1, and an upper bushing 201 inside the upper mold 101; a fixing component, which is located between the lower mold 1 and the lower bushing 2 and between the upper mold 101 and the upper bushing 201, and includes: mounting blocks 104, mounting holes 105, connecting holes 202, positioning blocks 4, and positioning grooves 401. Multiple mounting blocks 104 are connected to the outer sides of both the lower mold 1 and the upper mold 101. Mounting holes 105 are present on the surface of the mounting blocks 104. Multiple connecting holes 202 are provided on the outer surfaces of both the lower bushing 2 and the upper bushing 201. Multiple positioning blocks 4 are connected to the inner surfaces of both the lower mold 1 and the upper mold 101. Multiple positioning grooves 401 are provided on the outer surfaces of both the lower bushing 2 and the upper bushing 201. The mounting hole 105 corresponds to the connection hole 202. The mounting hole 105 is threaded with a mounting screw 106. Multiple positioning blocks 4 and positioning grooves 401 are evenly distributed, and the positioning blocks 4 and positioning grooves 401 correspond to each other. Multiple slots 3 are opened on the surfaces of the lower mold 1 and the upper mold 101. Two handles 301 corresponding to the slots 3 are connected to both ends of the lower bushing 2 and the upper bushing 201.

[0027] During bushing installation, the lower mold 1 and upper mold 101 are hoisted to designated positions with their openings facing upwards. Then, using the handle 301, a crane is used to hoist the lower bushing 2 and upper bushing 201, corresponding to the lower mold 1 and upper mold 101, respectively, onto the lower mold 1 and upper mold 101, and place them inside the lower mold 1 and upper mold 101. At this time, the positioning block 4 and positioning groove 401 provide initial positioning for the lower bushing 2 and upper bushing 201. Once the positioning block 4 is fully inserted into the positioning groove 401, the surfaces of the lower bushing 2 and upper bushing 201 are flush with the lower mold 1 and upper mold 101. The surface of the upper mold 101 is flush with the mold, and the handle 301 is inserted into the slot 3 to complete the placement of the lower bushing 2 and the upper bushing 201. At the same time, the connecting holes 202 on the lower bushing 2 and the upper bushing 201 correspond to the mounting holes 105 on the lower mold 1 and the upper mold 101. The operator can directly use a tool to screw the mounting screw 106 through the mounting hole 105 and into the connecting hole 202 to complete the installation of the lower bushing 2 and the upper bushing 201. During the installation process, the operator does not need to perform multiple operations to align the holes and make the bushing and mold surfaces flush, which is convenient and quick and saves the time of bushing installation and replacement. During disassembly, the mounting screws 106 are removed, and the lower mold 1 and upper mold 101 are lifted off by using the crane hook and the handles 301 on the lower bushing 2 and upper bushing 201.

[0028] Reference Figure 3 As shown, both sides of the lower mold 1 and the upper mold 101 are connected to side plates 102. The side plates 102 have multiple fixing holes 103 on their surfaces, and the multiple fixing holes 103 are evenly distributed. The lower bushing 2 is connected to a wire threading plate 205.

[0029] After the bushing is installed, the reinforcing bars, steel cables, and seat rings are placed inside the lower bushing 2 and arranged into a circular skeleton for the cement pole. At the same time, the wire rope passes through the cable threading plate 205 and the lower mold 1 to facilitate the subsequent straightening and tightening of the wire rope. Then, special concrete is poured into the lower bushing 2 and shaped by the workers to wrap around the skeleton. The concrete surface is then smoothed with a trowel. The surface of the lower mold 1 is then cleaned. The upper mold 101 is then hoisted onto the lower mold 1 using a crane and the upper mold 101 and lower mold 1 are closed. At this time, the fixing holes 103 of the upper mold 101 and lower mold 1 are aligned. The molds are then tightened with bolts to complete the merging. The entire mold can then be hoisted onto a centrifuge for centrifugation.

[0030] Reference Figure 1 As shown, multiple sliding rings 107 are connected to the outer sides of the lower mold 1 and the upper mold 101. The multiple sliding rings 107 are evenly distributed. After the sliding rings 107 are placed on the groove of the rotating wheel of the centrifuge, the centrifugation acceleration operation can begin.

[0031] Reference Figure 3 and Figure 6 Both the lower bushing 2 and the upper bushing 201 have corresponding sealing grooves 203 on their surfaces. A sealing block 204 is provided in the sealing groove 203. The gap between the lower bushing 2 and the upper bushing 201 can be sealed by the sealing groove 203 and the sealing block 204.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
