Description

Technical Field

[0001] This utility model relates to the field of spiral pile processing technology, and more specifically, to a spiral pile spiral plate mechanical winding device. Background Technology

[0002] Helical piles (such as helical anchors and helical piles) are a type of foundation reinforcement component widely used in wind power foundations, photovoltaic supports, slope protection, and other engineering projects. Their core structure consists of a central shaft (steel pipe) and helical blades. The helical blades use a mechanical winding device to continuously coil and weld metal strips onto the central shaft, forming a stable helical structure.

[0003] Traditional spiral pile mechanical winding devices mainly include a feeding system, a roll forming mechanism, a winding mechanism, a welding system, and a control system. During operation, the metal strip is roll-formed, then spirally wound around a central axis and fixed by welding to ultimately form a complete spiral pile.

[0004] The front end of a spiral pile is usually designed to be conical (to facilitate screwing into the soil). However, when processing the conical section, traditional winding devices require frequent manual or semi-automatic adjustments to the winding height to ensure the fit between the spiral blade and the central shaft. Due to the variation in the diameter of the conical section, problems such as loosening of the spiral blade and poor welding can easily occur during the winding process, affecting the quality of the finished product. Different models of spiral piles require adjustments to the parameters of the winding mechanism, which is inconvenient. Therefore, improvements are needed. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a mechanical winding device for spiral pile spiral blades, which has the advantage of adaptive adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mechanical winding device for spiral pile spiral plates, comprising a support and a winding mechanism. The support includes a horizontal plate, with side plates welded to both sides of the horizontal plate. A linear module is bolted between the inner tops of the side plates. The winding mechanism includes a movable plate disposed above the linear module. A cylinder is disposed below the movable plate. A square groove is formed inside the cylinder. A square plate is slidably installed inside the square groove. A pressure sensor is bolted to the upper side of the square groove. A telescopic spring is elastically installed between the inner side of the pressure sensor and the inner side of the square plate. A round rod is welded to the lower side of the square plate. A rectangular plate is bolted to the lower side of the round rod. A vertical plate is welded to the lower left side of the rectangular plate. A winding rod is welded to the inner side of the vertical plate.

[0007] As a preferred technical solution of this utility model, a sleeve is movably sleeved on the outer side of the coiled rod, a connecting block is uniformly welded to the front end of the sleeve, an elastic clamping ring is glued to the front end of the connecting block, an outer ring block is welded to the outer side of the sleeve, a threaded groove is opened on the inner side of the front end of the outer ring block, a threaded ring is threaded on the inner side of the threaded groove, and a retaining ring is welded to the inner side of the threaded ring.

[0008] As a preferred embodiment of this utility model, a clamping and rotating mechanism is provided on the outer side of the left side plate, and the output end of the clamping and rotating mechanism extends to the inner side of the side plate and is provided with a helical ground pile rod.

[0009] As a preferred embodiment of this utility model, a cylinder is bolted to the top of the movable plate, and the output end of the cylinder is bolted to the top of the cylinder.

[0010] As a preferred embodiment of this utility model, a knob is welded to the front end of the threaded ring, and the knob is located on the front side of the outer ring block.

[0011] As a preferred embodiment of this utility model, the outer diameter of the front end of the elastic clamping ring is smaller than the outer diameter of the other end, the inner diameter of the inner end of the retaining ring is smaller than the inner diameter of the other end, and the inner side of the retaining ring is in contact with the outer side of the elastic clamping ring.

[0012] As a preferred embodiment of this utility model, a guide wheel is bolted to the inner side of the vertical plate, and the guide wheel is located below the winding rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model effectively solves the problem of frequent manual height adjustment required by traditional devices when processing conical helical piles through a closed-loop control system of pressure sensor and PLC. When the helical blade contacts the helical pile rod, the pressure sensor monitors the compressive force in real time, and the PLC automatically controls the lifting and lowering of the cylinder to achieve adaptive adjustment of the winding height, ensuring that the helical blade always maintains the best contact state with the pile rod. This design not only significantly improves the winding accuracy and welding quality of the conical section helical blade, but also greatly reduces the labor intensity of operators. The overall structure is simple and reliable, and it is particularly suitable for the automated production of variable diameter helical piles.

[0015] 2. This utility model achieves rapid installation and stable fixation of the spiral blade by using an adjustable elastic clamping ring in conjunction with the screw groove and the knob. During operation, simply rotating the knob will cause the threaded ring to drive the retaining ring to apply uniform radial pressure to the elastic clamping ring, making it tightly fit against the outer wall of the winding rod, effectively preventing the spiral blade from shifting or falling off during the winding process. This design not only simplifies the installation process of the spiral blade and shortens the changeover time, but also adapts to the fixing requirements of spiral blades of different thicknesses, significantly improving the versatility and production efficiency of the equipment.

Detailed Implementation

[0022] 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.

[0023] like Figures 1 to 5As shown, this utility model provides a mechanical winding device for spiral pile spiral plates, including a support 1 and a winding mechanism 2. The support 1 includes a horizontal plate 11, with side plates 12 welded to both sides of the horizontal plate 11. A linear module 14 is bolted between the inner sides of the top of the side plates 12. The winding mechanism 2 includes a movable plate 201 disposed above the linear module 14. A cylinder 203 is disposed below the movable plate 201. A square groove 204 is opened inside the cylinder 203. A square plate 207 is slidably installed inside the square groove 204. A pressure sensor 205 is bolted to the upper side of the square groove 204. A telescopic spring 206 is elastically installed between the inner side of the pressure sensor 205 and the inner side of the square plate 207. A round rod 208 is welded to the lower side of the square plate 207. A rectangular plate 209 is bolted to the lower side of the round rod 208. A vertical plate 210 is welded to the lower left side of the rectangular plate 209. A winding rod 211 is welded to the inner side of the vertical plate 210.

[0024] In use, the spiral ground stake rod 3 is clamped and fixed by the clamping and rotating mechanism 13. Then, the spiral blade is sleeved on the outside of the coiled rod 211, and then the sleeve 213 is inserted and fixed to the coiled rod 211 to prevent the spiral blade from falling off. One end of the spiral blade extends to the surface of the spiral ground stake rod 3 through the guide wheel 212. At this time, the cylinder 202 drives the cylinder 203 to move downward, and the cylinder 203 drives the round rod 208 to move downward, so that one end of the spiral blade is tightly attached to the spiral ground stake rod 3. At this time, the round rod 208 retracts into the inside of the square groove 204, so that the square plate 207 compresses the telescopic spring 206, and the pressure sensor 205 receives the telescopic spring. When the compressive force of spring 206 reaches a threshold value, a signal is transmitted to the PLC, thereby stopping the operation of cylinder 202. At this time, the operator welds the spiral blade to the surface of the spiral ground pile rod 3, and starts the clamping rotation mechanism 13 and the linear module 14. The clamping rotation mechanism 13 drives the spiral ground pile rod 3 to rotate, and the linear module 14 drives the coiling rod 211 to move to the left. At this time, the compressive force between the spiral blade and the spiral ground pile rod 3 increases. The pressure sensor 205 receives the signal and controls the cylinder 202 to retract through the PLC, thereby driving the coiling rod 211 to move upward, so that it adapts to the distance between the coiling rod 211 and the spiral ground pile rod 3.

[0025] The closed-loop control system of pressure sensor 205 and PLC effectively solves the problem of frequent manual height adjustment required by traditional equipment when processing conical helical piles. When the helical blade contacts the helical pile rod 3, pressure sensor 205 monitors the extrusion pressure in real time, and the PLC automatically controls the lifting and lowering of cylinder 202 to achieve adaptive adjustment of the winding height, ensuring that the helical blade always maintains the best contact with the pile rod. This design not only significantly improves the winding accuracy and welding quality of the conical section helical blade, but also greatly reduces the labor intensity of operators. The overall structure is simple and reliable, and is particularly suitable for the automated production of variable diameter helical piles.

[0026] Among them, a sleeve 213 is movably sleeved on the outer side of the coiled rod 211, a connecting block 214 is uniformly welded to the front end of the sleeve 213, an elastic clamping ring 215 is glued to the front end of the connecting block 214, an outer ring block 216 is welded to the outer side of the sleeve 213, a threaded groove 217 is opened on the inner side of the front end of the outer ring block 216, a threaded ring 218 is threaded on the inner side of the threaded groove 217, and a retaining ring 219 is welded to the inner side of the threaded ring 218.

[0027] Sleeve 213 is fitted onto the outside of the winding rod 211, and then knob 220 is rotated to make knob 220 drive threaded ring 218 to rotate inside threaded groove 217, thereby driving retaining ring 219 to move inward, so that retaining ring 219 squeezes the outside of elastic clamping ring 215, causing elastic clamping ring 215 to deform and contract inward under the squeezing force, thereby squeezing and fixing elastic clamping ring 215 to the outer wall of winding rod 211, thereby installing outer ring block 216 on the outside of winding rod 211, thereby preventing spiral blade from detaching from winding rod 211.

[0028] By employing an adjustable elastic clamping ring 215 in coordination with the threaded groove 217 and the knob 220, the spiral blades are quickly installed and securely fixed. During operation, simply rotating the knob 220 allows the threaded ring 218 to drive the retaining ring 219 to apply uniform radial pressure to the elastic clamping ring 215, ensuring it fits tightly against the outer wall of the winding rod 211, effectively preventing the spiral blades from shifting or falling off during winding. This design not only simplifies the installation process of the spiral blades and shortens the changeover time, but also adapts to the fixing requirements of spiral blades of different thicknesses, significantly improving the versatility and production efficiency of the equipment.

[0029] The left side plate 12 is provided with a clamping and rotating mechanism 13 on its outer side. The output end of the clamping and rotating mechanism 13 extends to the inner side of the side plate 12 and is provided with a spiral ground pile rod 3.

[0030] The left end of the spiral ground pile rod 3 is fixed by the clamping and rotating mechanism 13 to ensure stable rotation during processing and avoid eccentric swaying. This structure simplifies the clamping process, improves positioning accuracy, and is particularly suitable for continuous winding operations of long ground pile rods.

[0031] Among them, a cylinder 202 is bolted on the upper part of the movable plate 201, and the output end of the cylinder 202 is bolted to the upper part of the cylinder 203.

[0032] The bolted connection between cylinder 202 and movable plate 201 facilitates adjustment and maintenance, and provides stable downward pressure; this design enables precise lifting and lowering control of the winding mechanism, ensuring constant contact pressure between the spiral blade and the ground pile rod.

[0033] Among them, the front end of the threaded ring 218 is welded with a knob 220, which is located on the front side of the outer ring block 216.

[0034] The external design of the knob 220 facilitates manual operation, and quick locking is achieved through the threaded ring 218; this structure improves the fixing efficiency of the spiral blade, and the operator can intuitively adjust the clamping force.

[0035] Among them, the outer diameter of the front end of the elastic clamping ring 215 is smaller than the outer diameter of the other end, the inner diameter of the inner end of the retaining ring 219 is smaller than the inner diameter of the other end, and the inner side of the retaining ring 219 is in contact with the outer side of the elastic clamping ring 215.

[0036] The tapered elastic clamping ring 215 and the retaining ring 219 form a progressive clamping, avoiding stress concentration; this structure ensures that the spiral blade is subjected to uniform force, prevents deformation and damage, and improves the reliability of fixation.

[0037] Among them, the guide wheel 212 is bolted on the inner side of the vertical plate 210, and the guide wheel 212 is located below the coiling rod 211.

[0038] The installation position of the guide wheel 212 optimizes the strip inlet angle and reduces frictional resistance; this design ensures accurate spiral blade winding trajectory, improves molding quality, and reduces material loss.

[0039] Working principle and usage process of this utility model:

[0040] In use, the spiral ground stake rod 3 is clamped and fixed by the clamping and rotating mechanism 13. Then, the spiral blade is sleeved on the outside of the coiled rod 211, and then the sleeve 213 is inserted and fixed to the coiled rod 211 to prevent the spiral blade from falling off. One end of the spiral blade extends to the surface of the spiral ground stake rod 3 through the guide wheel 212. At this time, the cylinder 202 drives the cylinder 203 to move downward, and the cylinder 203 drives the round rod 208 to move downward, so that one end of the spiral blade is tightly attached to the spiral ground stake rod 3. At this time, the round rod 208 retracts into the inside of the square groove 204, so that the square plate 207 compresses the telescopic spring 206, and the pressure sensor 205 receives the telescopic spring. When the compressive force of spring 206 reaches a threshold value, a signal is transmitted to the PLC, thereby stopping the operation of cylinder 202. At this time, the operator welds the spiral blade to the surface of the spiral ground pile rod 3, and starts the clamping rotation mechanism 13 and the linear module 14. The clamping rotation mechanism 13 drives the spiral ground pile rod 3 to rotate, and the linear module 14 drives the coiling rod 211 to move to the left. At this time, the compressive force between the spiral blade and the spiral ground pile rod 3 increases. The pressure sensor 205 receives the signal and controls the cylinder 202 to retract through the PLC, thereby driving the coiling rod 211 to move upward, so that it adapts to the distance between the coiling rod 211 and the spiral ground pile rod 3.

[0041] Sleeve 213 is fitted onto the outside of the winding rod 211, and then knob 220 is rotated to make knob 220 drive threaded ring 218 to rotate inside threaded groove 217, thereby driving retaining ring 219 to move inward, so that retaining ring 219 squeezes the outside of elastic clamping ring 215, causing elastic clamping ring 215 to deform and contract inward under the squeezing force, thereby squeezing and fixing elastic clamping ring 215 to the outer wall of winding rod 211, thereby installing outer ring block 216 on the outside of winding rod 211, thereby preventing spiral blade from detaching from winding rod 211.
