Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically a wire winding device for processing large-diameter PCCP pipes. Background Technology

[0002] PCCP pipe, or prestressed concrete cylinder pipe, refers to a water pipe made by winding circumferential prestressed steel wires around a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on top. PCCP pipe is a composite pipe composed of thin steel plates, high-strength steel wires, and concrete, possessing high sealing performance, high strength, and high impermeability. During the processing of large-diameter PCCP pipes, after pouring a high-strength concrete layer onto the steel cylinder, the pipe body is usually placed upright on a wire-winding device. The device drives the pipe body to rotate, causing the steel wires to gradually wind around it. Currently, the wire-winding device for large-diameter PCCP pipe processing typically involves hoisting the steel cylinder with the concrete layer onto the device, and using a drive structure to rotate the cylinder for wire winding. However, due to the relatively heavy weight of the steel cylinder with the concrete layer, during hoisting, the rotation center of the drive structure's output end may deviate from the cylinder's axis. This can lead to inconsistent wire winding tightness, hindering the smooth progress of the winding process. Utility Model Content

[0038] 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.

[0039] Please see Figure 1-7 In this embodiment of the present invention, the wire winding device for processing large-diameter PCCP pipes includes a support module 100 and a guide module 200.

[0040] The support module 100 can support the PCCP pipe. The support module 100 includes a drive mechanism 110. The top of the drive mechanism 110 is provided with an adjustment frame 140. The top of the adjustment frame 140 is provided with a support plate 130. Two sliding blocks 143 are slidably connected to the inner side of the adjustment frame 140. An adjustment screw 142 that is rotatably connected to the inner side of the adjustment frame 140 is screwed into the sliding block 143. An adjustment seat 150 is fixedly connected to the opposite side of the two sliding blocks 143. Two sliding blocks 153 are slidably connected to the inner side of the adjustment seat 150. An adjustment screw 152 that is rotatably connected to the side of the sliding block 153 is screwed into the side of the sliding block 153. The adjustment screw 142 and the adjustment screw 152 are perpendicular to each other. A U-shaped frame 132 that is fixedly connected to the side of the two sliding blocks 153 is fixedly connected to the bottom surface of the support plate 130.

[0041] A connecting groove is provided on the inner top surface of the support plate 130. Several rolling rods 133 are rotatably connected to the inner side of the connecting groove. Several rolling rods 156 are rotatably connected to the bottom of the adjusting seat 150. The bottom side of the rolling rods 133 contacts the top surface of the adjusting seat 150, and the rolling rods 133 facilitate the movement of the U-shaped frame 132 along the top of the adjusting seat 150. The bottom side of the rolling rods 156 contacts the top surface of the rotating plate 190, and the rolling rods 156 facilitate the movement of the adjusting seat 150 along the inside of the adjusting frame 140. The top of the drive mechanism 110 is provided with a rotating plate 190 fixedly connected to the bottom surface of the adjusting frame 140. Several ball seats 131 are fixedly connected to the bottom surface of the support plate 130 corresponding to the rotating plate 190. The balls in the ball seats 131 contact the top surface of the rotating plate 190. The rotating plate 190 can support the edge of the support plate 130 through the ball seats 131. The guide module 200 is provided on one side of the support module 100.

[0042] Specifically, after placing the steel cylinder with the concrete layer on the support plate 130, if there is a certain deviation between the axis of the steel cylinder and the rotation center, the adjusting screw 142 and the adjusting screw 152 can be rotated. The rotation of the adjusting screw 142 can cause the sliding block 143 to move along the inside of the adjusting frame 140. The sliding block 143 can drive the adjusting seat 150 to move along the adjusting screw 142. The adjusting seat 150 can drive the support plate 130 to move. The rotation of the adjusting screw 152 can cause the sliding block 153 to move along the inside of the adjusting seat 150. The sliding block 153 can drive the U-shaped frame 132 to move along the adjusting screw 152, thereby causing the support plate 130 to move along the XY axis. This adjusts the position of the support plate 130 and the steel cylinder with the concrete layer, so that the axis of the steel cylinder is aligned with the rotation center as much as possible. This is beneficial for the steel wire to be wound more evenly on the steel cylinder with the concrete layer, and it is beneficial for the wire winding to proceed smoothly. During the winding process, the steel wire can be guided by the guiding module 200.

[0043] Example 1

[0044] like Figure 5 As shown, in this embodiment, a power motor 141 is fixedly connected inside the adjustment frame 140. The output end of the power motor 141 is connected to the end of an adjustment screw 142. A linkage rod 144 is rotatably connected to the side of the adjustment frame 140 away from the power motor 141. Both ends of the linkage rod 144 and the ends of the two adjustment screws 142 are fixedly sleeved with bevel gears 145, and adjacent bevel gears 145 mesh and transmit power.

[0045] A second power motor 151 is fixedly connected inside the adjusting seat 150. The output end of the second power motor 151 is connected to the end of an adjusting screw 152. A second linkage rod 154 is rotatably connected inside the adjusting seat 150 to the end of the second adjusting screw 152. Both ends of the linkage rod 154 are fixedly sleeved with bevel gears 155 at the ends of the two adjusting screws 152. The two adjacent bevel gears 155 mesh and drive each other. The two adjusting screws 142 are linked to the linkage rod 144 through the bevel gears 145, and the two adjusting screws 152 are linked to the linkage rod 154 through the bevel gears 155. The threads on the two adjusting screws 142 have opposite directions of rotation, and the threads on the two adjusting screws 152 have opposite directions of rotation.

[0046] In specific implementation, the power motor 141 can drive an adjusting screw 142 to rotate. The adjusting screw 142 can drive the linkage rod 144 to rotate through two corresponding bevel gears 145. The linkage rod 144 can drive the other adjusting screw 142 to rotate through two corresponding bevel gears 145, so that the two adjusting screws 142 rotate synchronously. The power motor 151 can drive an adjusting screw 152 to rotate. The adjusting screw 152 can drive the other adjusting screw 152 to rotate through the linkage rod 154 and the bevel gear 155. In this way, the position of the support plate 130 and the steel cylinder can be adjusted.

[0047] like Figure 3-4 As shown, in this embodiment, the drive mechanism 110 includes a fixed box 111, a drive motor 113, a transmission shaft 114, a connecting gear 115, and a connecting gear ring 116.

[0048] The fixed box 111 is rotatably connected to the bottom surface of the rotating plate 190, and the rotating plate 190 is rotatably set on the top surface of the fixed box 111. The drive motor 113 is fixedly connected to the inner bottom surface of the fixed box 111. The transmission shaft 114 is rotatably connected to the inner side surface of the fixed box 111. The output end of the drive motor 113 is connected to the bottom end of the transmission shaft 114. The connecting gear 115 is fixedly sleeved on the side surface of the transmission shaft 114. The connecting gear ring 116 is set inside the fixed box 111. The top surface of the connecting gear ring 116 is fixedly connected to the bottom surface of the rotating plate 190. The connecting gear ring 116 meshes with the connecting gear 115 for transmission.

[0049] In practice, when adjusting the position of the support plate 130 and the steel cylinder, the axis of the steel cylinder can be aligned with the axis of the rotating plate 190 as much as possible. The drive motor 113 can drive the transmission shaft 114 to rotate. The transmission shaft 114 can rotate the connecting gear 115 to make the connecting gear ring 116 rotate, thereby causing the rotating plate 190 to rotate. The rotating plate 190 can drive the adjusting frame 140 to rotate, and the adjusting frame 140 can drive the adjusting seat 150 to rotate, thereby causing the support plate 130 and the steel cylinder to rotate, and the steel wire is wound on the concrete layer of the steel cylinder.

[0050] Example 2

[0051] Based on Example 1, such as Figure 3-4 As shown, in this embodiment, a base plate 120 is provided at the bottom of the drive mechanism 110, which can be fixed on the ground to position the drive mechanism 110. The top surface of the base plate 120 is fixedly connected to the bottom surface of the fixed box 111. Two fixed seats 160 are fixedly connected to the top surface of the base plate 120, and an electric telescopic rod 161 is provided inside the fixed seat 160.

[0052] A connecting ring 170 is provided on the side of the support plate 130. Two detection seats 171 and two detection seats 172 are fixedly connected at equal intervals on the top surface of the connecting ring 170. The two detection seats 171 and the two detection seats 172 are distributed opposite to each other. A distance sensor 180 is provided inside both the detection seats 171 and the two detection seats 172. Two push blocks 173 are fixedly connected to the inner side of the connecting ring 170 corresponding to the fixed seat 160. The output end of the electric telescopic rod 161 is connected to the bottom surface of the adjacent push block 173 through a transmission connection.

[0053] In practice, after the steel cylinder is placed on the support plate 130, the position of the steel cylinder can be detected by the distance sensor 180. Based on the distance data deviation detected by the distance sensors 180 on the two detection seats 171, the second power motor 151 is started to adjust the position of the support plate 130. Based on the distance data deviation detected by the distance sensors 180 on the two detection seats 172, the first power motor 141 is started to adjust the position of the support plate 130. When the distance data detected by the distance sensors 180 on the two detection seats 171 are equal, and the distance data detected by the distance sensors 180 on the two detection seats 172 are equal, the axis of the steel cylinder is aligned with the axis of the rotating plate 190, that is, the axis of the steel cylinder is aligned with the rotation center. The position of the steel cylinder with the concrete layer can be automatically adjusted according to the detection data, which can adapt to the adjustment of steel cylinders of different sizes.

[0054] like Figure 1-2 As shown, in this embodiment, the guide module 200 includes a column 210, a lifting block 240, a guide plate 250, a chassis 220, and several triangular plates 230.

[0055] The column 210 is located on one side of the drive mechanism 110. A lifting screw 211 is rotatably connected to the inner side of the column 210. A connecting motor 212 is fixedly connected to the bottom of the column 210. The output end of the connecting motor 212 is connected to the bottom end of the lifting screw 211. A lifting block 240 is slidably connected to the inner side of the column 210. The lifting block 240 is screwed to the side of the lifting screw 211. A guide plate 250 is fixedly connected to the side of the lifting block 240. A round hole is opened on the side of the guide plate 250. The chassis 220 is fixedly connected to the bottom end of the column 210. The chassis 220 can be fixed on the ground to position the column 210. Several triangular plates 230 are fixedly connected to the top surface of the chassis 220 and the side of the column 210. The chassis 220 can support the column 210 through the triangular plates 230.

[0056] In practice, the steel wire can be passed through the inside of the round hole and guided through the round hole. When winding the wire, the matching wire winding equipment releases the steel wire. Then, the drive mechanism 110 rotates the steel cylinder with the concrete layer, and the connecting motor 212 drives the lifting screw 211 to rotate. The rotation of the lifting screw 211 can cause the lifting block 240 to move downward along the inside of the column 210, so that the guide plate 250 pulls the steel wire downward, thereby making the steel wire spirally wound on the concrete layer of the steel cylinder.

[0057] An additional guide module 200 can be configured. The guide plate 250 is no longer set on the lifting block 240 of the newly configured guide module 200. Instead, a fixed ring is fixedly set on the lifting block 240, and a rotating ring is rotatably set inside the fixed ring. The fixed ring and the rotating ring correspond to the top of the support module 100. After the steel cylinder is placed on the support plate 130, the connecting motor 212 of the new guide module 200 drives the lifting screw 211 to rotate, lowering the fixed ring and the rotating ring, so that the rotating ring is inserted into the inside of the steel cylinder to limit the movement of the steel cylinder. The bottom side of the rotating ring can be set as a conical surface, so that the conical surface abuts against the inner ring of the top of the steel cylinder. This allows for the fixing of steel cylinders of different sizes.

[0058] The newly configured guide module 200 can be placed on a base that can move automatically. When hoisting the steel cylinder, the newly configured guide module 200 can be removed from the top of the support module 100.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
