Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine setting-out technology, specifically a wire drawing machine setting-out device for concrete pipe piles. Background Technology

[0002] With the increasing importance of modern buildings and the continuous increase in building height, higher requirements are placed on the bearing capacity of the foundation. Natural foundations can no longer adequately bear the loads transmitted from the superstructure. Therefore, when using natural foundations to construct buildings, there is a way to enhance the bearing capacity, namely, using concrete pipe piles as the foundation piles. Currently, in the production process of pipe piles, steel bars and steel wires are needed to connect them into a steel cage. Before the steel wires are made into a steel cage, they first need to be drawn using a wire drawing machine.

[0003] When using a wire drawing machine, a wire feeding device is needed to assist in wire feeding. The speed of wire feeding determines the efficiency of the work. When using the wire feeding device to determine the direction, a spool with wire is usually fixed to the device, and then one end of the wire is fixed to the wire drawing machine for wire feeding.

[0004] During the wire feeding process, the wire may become entangled on the outside of the feeding frame, and the wire reel may become loose, causing the wire to become crossed or tangled. This results in a chaotic feeding path, making it impossible to feed the wire smoothly in the predetermined order and direction, affecting the feeding efficiency and the normal progress of subsequent processing. In severe cases, it may even lead to feeding interruption. Therefore, it is necessary to provide a feeding device that can open up the wire, stabilize the feeding path, and improve feeding efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a wire-laying device for a concrete pipe pile wire drawing machine, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a wire laying device for a concrete pipe pile drawing machine, comprising:

[0007] The base plate, the placement platform, the fixing tube, and the steel wire are provided. The placement platform is fixed to the middle of the upper surface of the base plate, the fixing tube is fixed to the center of the upper surface of the placement platform, and the steel wire is wrapped around the outside of the fixing tube.

[0008] The expansion assembly includes an installation tube, a first movable groove, an electric push rod, and a movable column. The installation tube is fixed to the upper surface of the fixed tube. There are four first movable grooves, which are equally spaced on the outer surface of the fixed tube. The electric push rod is fixed in the middle of the installation tube. The movable column slides through the inside of the fixed tube, and one end of the movable column is fixed to the output end of the electric push rod.

[0009] Furthermore, a wire feeding frame is fixed to one side of the base plate, and two pulleys are fixed to the upper end of the wire feeding frame, with the pulleys in contact with the steel wire.

[0010] Furthermore, the upper surface of the placement platform is provided with four second movable slots, and the outer surface of the movable column is fixed with four first connecting plates, and one side of the first connecting plate is provided with a first mounting slot.

[0011] Furthermore, a first connecting rod is rotatably passed through the upper end of the first mounting groove, a second connecting rod is rotatably passed through the lower end of the first mounting groove, and a second connecting plate is rotatably passed through the other end of the first and second connecting rods, with the lower end of the second connecting plate slidingly passing through the second movable groove.

[0012] Furthermore, a second mounting groove is provided on one side of the interior of the second connecting plate, and the first connecting rod and the second connecting rod are respectively on the upper and lower sides of the second mounting groove. A support plate is fixed on one side of the second connecting plate, and the outer surface of the support plate is in contact with the steel wire.

[0015] This utility model has the following beneficial effects:

[0016] This utility model comprises a base plate, a placement platform, a fixed tube, steel wire, a wire feeding frame, pulleys, and a spreading assembly. When feeding steel wire, the wire is placed on the placement platform. Then, according to the size of the wire roll, an external controller controls the extension and retraction of an electric push rod. The extension of the electric push rod drives the movable column (23) to move downward within the fixed tube. The movable column simultaneously drives the first connecting plate to move downward. The first connecting plate simultaneously drives one end of the first connecting rod and the second connecting rod to move downward, causing the other end of the first connecting rod and the second connecting rod to push the second connecting plate, causing the second connecting plate to move outward within the second movable groove. The second connecting plate drives the support plate to move outward, spreading the steel wire and preventing it from being loosely placed on the placement platform. The external controller adjusts the extension and retraction of the electric push rod according to the diameter and remaining amount of the wire roll, so that the spreading range of the support plate matches the size of the wire roll, reducing path confusion and shaking during the feeding process, and ensuring that the steel wire smoothly enters the subsequent process along a fixed trajectory.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a wire laying device for a concrete pipe pile drawing machine, comprising:

[0029] The base plate 11, the placement platform 12, the fixing tube 13 and the steel wire 14 are provided. The placement platform 12 is fixed in the middle of the upper surface of the base plate 11, the fixing tube 13 is fixed in the center of the upper surface of the placement platform 12, and the steel wire 14 is wrapped around the outside of the fixing tube 13. A wire feeding frame 15 is fixed on one side of the base plate 11. Two pulleys 16 are fixed at the upper end of the wire feeding frame 15, and the pulleys 16 are in contact with the steel wire 14.

[0030] The base plate 11 serves as the basic support structure for the entire wire feeding device, providing a stable installation platform for components such as the placement platform 12 and the fixing tube 13. The placement platform 12 is used to support the wire 14 roll and the fixing tube 13. The fixing tube 13 serves as the axis of the wire 14 roll and fixes the wire 14 roll.

[0031] The expansion assembly includes an installation tube 21, a first movable groove 211, an electric push rod 22, and a movable column 23. The installation tube 21 is fixed to the upper surface of the fixed tube 13. There are four first movable grooves 211, which are equally spaced on the outer surface of the fixed tube 13. The electric push rod 22 is fixed to the middle of the installation tube 21. The movable column 23 slides through the inside of the fixed tube 13, and one end of the movable column 23 is fixed to the output end of the electric push rod 22.

[0032] The mounting tube 21 serves as the mounting base for the electric push rod 22, ensuring that the force direction of the electric push rod 22 is consistent with the movement direction of the movable column 23. The first mounting groove 241 provides space for the rotation of the first connecting rod 25 and the second connecting rod 26. The electric push rod 22 serves as a power source to drive the movable column 23 to move up and down.

[0033] The upper surface of the placement platform 12 is provided with four second movable slots 212, and four first connecting plates 24 are fixed on the outer surface of the movable column 23. A first mounting slot 241 is provided on one side of the first connecting plate 24. A first connecting rod 25 is rotatably passed through the upper end of the first mounting slot 241, and a second connecting rod 26 is rotatably passed through the lower end of the first mounting slot 241. The other ends of the first connecting rod 25 and the second connecting rod 26 are rotatably passed through the second connecting plate 27, and the lower end of the second connecting plate 27 slides through the second movable slot 212.

[0034] The first connecting plate 24 moves up and down with the movable column 23, serving as the mounting base for the first connecting rod 25 and the second connecting rod 26. The first connecting rod 25 and the second connecting rod 26 rotate through the first mounting groove 241 and the second mounting groove 271, forming a lever mechanism that converts the vertical movement of the movable column 23 into the lateral movement of the second connecting plate 27.

[0035] A second mounting groove 271 is provided on one side of the interior of the second connecting plate 27. The first connecting rod 25 and the second connecting rod 26 are respectively on the upper and lower sides of the second mounting groove 271. A support plate 28 is fixed on one side of the second connecting plate 27, and the outer surface of the support plate 28 is in contact with the steel wire 14.

[0036] The second connecting plate 27 moves outward as pushed by the first connecting rod 25 and the second connecting rod 26, and the support plate 28 separates the steel wire 14 coils by the lateral spreading force.

[0037] Working principle:

[0038] When the wire 14 is laid out, the wire 14 is placed on the placement table 12. Then, according to the size of the wire 14 roll, the electric push rod 22 is extended and retracted by the external controller. The extension of the electric push rod 22 drives the movable column 23 to move downward in the fixed tube 13. The movable column 23 simultaneously drives the first connecting plate 24 to move downward. The first connecting plate 24 simultaneously drives one end of the first connecting rod 25 and the second connecting rod 26 to move downward, so that the other end of the first connecting rod 25 and the second connecting rod 26 pushes the second connecting plate 27, so that the second connecting plate 27 moves outward in the second movable groove 212. The second connecting plate 27 drives the support plate 28 to move outward, spreading the wire 14 and preventing the wire 14 from being placed loosely on the placement table 12.

[0039] In this step, the extension and retraction of the electric push rod 22 is adjusted by an external controller according to the diameter and remaining amount of the wire 14 coil. This ensures that the opening range of the support plate 28 matches the size of the wire 14 coil, reducing path confusion and shaking during the wire feeding process and ensuring that the wire 14 smoothly enters the subsequent process along a fixed trajectory.

[0040] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The lubrication assembly includes a lubrication box 31, a feed inlet 32, and a discharge pipe 33. The lubrication box 31 is fixed on the upper surface of the wire feeding frame 15, the feed inlet 32 ​​is fixed on the upper surface of the lubrication box 31, and the discharge pipe 33 is fixedly connected to the lower surface of the lubrication box 31. A feeding roller 34 rotates through the inside of the discharge pipe 33 and contacts the steel wire 14. Lubricating powder is placed inside the lubrication box 31.

[0042] The lubrication box 31 provides a stable powder supply for the lubrication system. The feed port 32 is used to add lubricating powder into the lubrication box 31. The discharge pipe 33 serves as the output channel for the lubricating powder, conveying the lubricating powder from the lubrication box 31 to the feed roller 34. The feed roller 34 contacts the surface of the steel wire 14 and rotates to carry the lubricating powder out from the discharge pipe 33 and cover the surface of the steel wire 14.

[0043] Working principle:

[0044] By pulling out the end of the wire 14, the end of the wire 14 is pulled out from the surface of the pulley 16 on the wire feeding frame 15. During the wire feeding process, the feed roller 34 contacts the wire 14, and the feed roller 34 rotates, bringing out the lubricating powder from the discharge pipe 33 and covering the outer surface of the wire 14.

[0045] This step, through the coordinated design of the feeding roller 34 and the lubricating powder, achieves dynamic coverage of the lubricating layer on the surface of the steel wire, reducing the friction and wear of the steel wire 14.
