Description

Technical Field

[0001] This utility model mainly relates to the field of steel mesh welding and processing, specifically a wire winding and unwinding device for welding steel mesh. Background Technology

[0002] Currently, steel mesh in factories is generally divided into two types: one is made of welded steel bars, and the other is made of welded coarse steel wire. For steel mesh made of welded coarse steel wire, a wire winding and unwinding device is required in the welding process to feed the wire to the welding equipment; and existing wire winding and unwinding devices on the market, such as... Figure 1 , Figure 2 As shown, a hydraulic device B is installed between the support base A and the bearing plate C. The bearing plate C is rotatably connected to the support base A. The hydraulic device B pushes the bearing plate C to rotate on the support base A. A wire coil placement rack D is also installed on the bearing plate C. The wire coil is placed on the wire coil placement rack D, which is a cylinder and is fixedly connected to the bearing plate C. In use, to save effort when placing the wire coil, the hydraulic device rotates the bearing plate C from the support base A by a certain angle so that the bearing plate C is placed vertically. Then, the wire coil is placed on the wire coil placement rack D. Then, the hydraulic device is used to place the bearing plate C into a horizontal state. The purpose of leveling the bearing plate C is to make it easier to pick up the wire. The method of picking up the wire is to attach one end of the wire to the traction machine and pull the wire with the traction machine. During the pulling process, the entire wire coil rotates on the wire coil placement rack D.

[0003] However, this type of wire coil unloading device has the following problems: First, if the wire coil is relatively heavy, it may break the hydraulic device B through the bearing plate C. Second, after the wire coil is placed on the wire coil placement rack D, it rotates on the rack when the wire is picked up. Since the rack D is a cylinder, the bottom and sides of the wire coil will wear against the surface of the bearing plate C and the side of the rack D, respectively, which will reduce the service life of the bearing plate C and the rack D. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the prior art and provide a wire winding and unwinding device for welding steel mesh.

[0005] To achieve the above objectives, the technical solution of the present invention is to design a wire winding and unwinding device for welding steel mesh, comprising a support plate hinged to a base; a hydraulic device provided between the support plate and the base; a flexible cable provided between the base and the support plate; a support platform rotatably connected to the support plate, and a bearing provided between the support plate and the support platform; and a placement frame fixedly connected to the support platform.

[0006] To prevent the hydraulic device between the support plate and the base from breaking due to the wire coil suddenly falling onto the placement rack during placement, a further preferred technical solution is that a base connecting block is fixedly connected to the base, and a first base support is fixedly mounted on the base connecting block; a first support plate support is fixedly mounted on the support plate; one end of the flexible cable is connected to the first base support, and the other end of the flexible cable is connected to the first support plate support. To make placing the wire coil into the placement rack easier, the support plate is usually rotated a certain angle from the base using the hydraulic device to make the support plate vertical before placing the wire coil.

[0007] To prevent damage to components mounted on the support plate after it is laid flat, a further preferred technical solution is to provide a support block on each side of the support plate near the base. When the support plate is laid flat, the two support blocks support the support plate, and other components connected to the support plate do not contact the ground.

[0008] To reduce the friction between the wire coil and the placement frame, a further preferred technical solution is to rotatably mount a support platform on the side of the support plate facing away from the base, and fix the placement frame to the side of the support platform facing away from the support plate. The placement frame includes limiting posts and limiting rings. At least three limiting posts are provided, with one end fixedly connected to the support plate and the other end collectively supporting a limiting ring. The wire coil placed on the placement frame is usually circular, with its inner diameter circle fitting against the limiting posts and limiting rings. After placing the wire coil on the placement frame and flattening the support plate, one end of the wire is connected to a traction machine for taking the wire. Typically, one end of the wire is located on the outer diameter circle of the wire coil. When the traction machine pulls the wire from the wire coil, the wire coil is subjected to lateral tension. Because the wire coil is fitted against the limiting frame, the lateral tension causes the placement frame and support platform to rotate on the support plate. The wire coil rotates with the placement frame while being pulled by the traction machine.

[0009] To prevent the hydraulic device from being broken due to excessive force, and the tension between the support plate and the base from acting on it again, thus breaking the hydraulic device, a further preferred technical solution is that a second base support is fixedly installed on the base connecting block, and a second support plate support is also installed on the support plate; one end of the connecting rod is hinged to the second base support, and the other end of the connecting rod is hinged to the second support plate support; the other end of the first connecting rod is hinged to the other end of the second connecting rod; the first connecting rod and the second connecting rod are either taut between the base and the support plate or detached and taut between the base and the support plate, and the tension borne by the connecting rod is greater than the tension borne by the flexible cable. If the wire coil suddenly falls into the placement frame for other reasons, the flexible cable is taut between the base and the support plate. If the flexible cable fails to withstand the sudden force and breaks, the first connecting rod and the second connecting rod will inherit the tension between the base and the support plate. The flexible cable is a chain.

[0010] The advantages and beneficial effects of this invention are as follows:

[0011] First, to prevent the hydraulic system between the support plate and the base from breaking due to the wire coil suddenly falling onto the placement rack during placement, a flexible cable is installed between the base and the support plate, adding an extra layer of safety to the hydraulic system. Second, to prevent the flexible cable from breaking under sudden force, connecting rod one and connecting rod two are installed between the base and the support plate, adding another layer of safety to the hydraulic system.

[0012] Second, during the process of taking the steel wire, the steel wire roll rotates in the placement frame. In order to reduce the friction between the steel wire roll and the placement frame, the placement frame is set on a rotating support platform, that is, the placement frame rotates together with the steel wire roll when taking the steel wire.

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] Reference Figure 3 As shown, a wire winding and unwinding device for welding reinforcing mesh is disclosed. One end of a support plate 16 is hinged to one end of a base 10. A hydraulic device 145 is installed between the support plate 16 and the base 10. The hydraulic device 145 includes a hydraulic cylinder 14 and a hydraulic rod 15. The end of the hydraulic cylinder 14 is hinged to the other end of the base 10, and the end of the hydraulic rod 15 is hinged to a connecting block 18 on the support plate 16. A flexible cable 21, a first connecting rod 22, and a second connecting rod 23 are also installed between the base 10 and the support plate 16. A support platform 24 is rotatably mounted on the support plate 16. The support platform 24 is rotatably connected to the support plate 16 via bearings; specifically, a bearing support block 29 is fixedly connected to the support plate 16. The support platform 24 has an installation groove 30 for embedding a bearing 28. The bearing support block 29 and the inner ring of the bearing 28 are interference-fitted, and the installation groove 30 and the outer ring of the bearing 28 are interference-fitted. A placement frame 25 is fixedly connected to the support platform 24. The wire winding is placed on the placement frame 25. In this embodiment, the flexible cord 21 is a chain.

[0023] Reference Figure 3 As shown, a base connecting block 18 is fixedly connected to each of the two sides of the other end of the base 10, and a base first support 12 is fixedly installed on each of the two base connecting blocks 18; two support plate first supports 19 are fixedly installed on the side of the support plate 16 near the base 10, and the two support plate first supports 19 are respectively located on both sides of the support plate 16 and are respectively opposite to the two base first supports 12 connected to the base 10. A flexible rope 21 is connected between each base first support 12 and its opposite support plate first support 19. To make it easier to place the wire coil onto the placement rack 25, the support plate 16 is usually rotated from the base 10 by a certain angle using the hydraulic device 145 before placement, so that the support plate 16 is placed vertically. When the support plate 16 is rotated to the predicted position, the flexible cable 21 is close to the taut state. The main function of the flexible cable 21 is to prevent the hydraulic device 145 between the support plate 16 and the base 10 from being pulled apart when the wire coil suddenly falls onto the placement rack 25 during placement. This adds an extra layer of protection to the hydraulic device 145.

[0024] Reference Figure 3As shown, a support block 17 is provided on each side of the support plate 16 near the base 10. After the wire coil is placed on the placement rack 25, the support plate 16 needs to be returned to a horizontal position. The support plate 16 near the base 10 is provided with a connecting block 18 for connecting the hydraulic rod 15, a first support plate 19 for connecting the flexible cable 21, and a second support plate 10 for installing one end of the second connecting rod 23. To prevent damage to these components, two support blocks 17 are fixedly installed on the support plate 16 near the base 10, with the two support blocks 17 located on both sides of the support plate 16. When the support plate 16 is leveled, the two support blocks 17 support the support plate 16, and other components connected to the support plate 16 do not contact the ground.

[0025] Reference Figure 3 , Figure 4.1 , Figure 4.2 , Figure 5 As shown, a support platform 24 is rotatably mounted on the side of the support plate 16 away from the base 10. A placement frame 25 is fixedly connected to the side of the support platform 24 away from the support plate 16. The placement frame 25 includes limiting posts 26 and limiting rings 27. At least three limiting posts 26 are provided. In this embodiment, three limiting posts 26 are provided, and one end of each is fixedly connected to the support platform 24, while the other end of each supports a limiting ring 27. The wire coil placed on the placement rack 25 is circular, with its inner diameter circle fitting against the limiting post 26 and the limiting ring 27. After placing the wire coil on the placement rack 25 and flattening the support plate 16, one end of the wire is connected to the wire-retrieving traction machine. Typically, one end of the wire is located on the outer diameter circle of the wire coil. When the traction machine pulls the wire from the wire coil, the wire coil is subjected to lateral tension. Because the wire coil is in contact with the limiting rack, the lateral tension causes the placement rack 25 and the support platform 24 to rotate on the support plate 16. The wire coil rotates with the placement rack 25 while being pulled by the traction machine. This not only reduces the friction between the wire coil and the placement rack but also increases the speed of wire retrieval.

[0026] Reference Figure 3As shown, each base connecting block 18 is also fixedly provided with a base second support 13, and the support plate 16 is also provided with two support plate second supports 20, with the two base second supports 13 respectively opposite to the two support plate second supports 20 on the support plate 16. Each base second support 13 is rotatably provided with a connecting rod 22 at one end, and the other end of each connecting rod 22 is rotatably provided with a connecting rod 23 at the other end, which is rotatably provided on the corresponding support plate second support 20. When the flexible cable 21 is in a taut state, the connecting rods 22 and 23 are in a non-taut state, and the tension on the connecting rods is greater than the tension on the flexible cable 21. The function of the connecting rods 22 and 23 is to prevent the tension between the support plate 16 and the base 10 from acting on the hydraulic device 145 again after the flexible cable 21 is broken by a large force, thereby breaking the hydraulic device 145. This adds another layer of protection to the hydraulic device 145.

[0027] The working principle of this utility model is as follows: Assuming that the placement frame 25 is unloaded at this time, the support plate 16 is first rotated from the base 10 to a vertical position by the hydraulic device 145. Then, the wire coil is placed on the placement frame 25. Assuming that the wire coil suddenly falls onto the placement frame 25 for other reasons, the flexible cable 21 is tightened between the base 10 and the support plate 16. If the flexible cable 21 fails to withstand the sudden force and breaks, the connecting rod 1 22 and the connecting rod 23 will inherit the tension between the base 10 and the support plate 16. After the wire coil is placed on the placement frame 25, the support plate 16 is flattened by the hydraulic device 145. After being flattened, only the support block 17 of the support plate 16 is in contact with the ground. Then, the head of the wire in the wire coil is fixed on the traction machine. When the traction machine is working, the wire coil is pulled by the traction machine while rotating with the placement frame 25.

[0028] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
