Abstract
Description
Technical Field
[0001] This utility model relates to a wire winding machine, and more particularly to an adjustable lifting structure for a wire winding machine. Background Technology
[0002] Currently, in production and processing, reinforced concrete cement pipes (RCP) or prestressed concrete cylinder pipes (PCCP) are produced using a vertical wire winding process.
[0003] To wind prestressed steel wire onto the outer wall of RCP or PCCP mandrels, a rotary table is needed to hold the mandrel and rotate it under the drive of a rotary motor. During the rotation of the mandrel by the rotary table, the pitch lifting trolley rises evenly, ensuring that the prestressed steel wire is wound onto the surface of the mandrel according to the designed pitch, meeting the process requirements.
[0004] The wire wrapping process is divided into three stages: 1. Initial stage: After hammering the reinforcing bar into the anchor block, the first 2-3 turns are wrapped using only 50% of the design stress, generally referred to as the semi-stress tight wrapping stage; 2. Middle stage: Wrapping is done using the design stress until near the end, generally referred to as the full stress stage; 3. Final stage: About 2-3 turns before the end, only 50% of the design stress is used for wrapping.
[0005] Because prestressed steel wire is high-strength steel wire with a high carbon content, it cannot be welded and can only be anchored using specialized tooling. For example... Figure 3 As shown, when the wire winding machine is wound to the top of the core, the prestressed steel wire is wound at half stress. When it cannot be aligned with the groove of the anchor block, the prestressed steel wire needs to be manually pried under half stress and inserted into the groove of the anchor block.
[0006] When winding prestressed steel wire with a diameter of Φ7mm or less, the half stress is only 2300N. If Φ10mm steel wire is to be wound, the half stress is about 4600N. Not only is the force doubled, making it difficult to pry, but the risk of personal injury should the steel wire break is also higher, posing a safety hazard. Utility Model Content
[0007] To address the above problems, this utility model provides an adjustable lifting structure for a wire winding machine that is simple in structure, easy to operate, and improves safety.
[0008] The technical solution of this utility model is: an adjustable wire winding machine lifting structure, including a lifting trolley, the lifting trolley being movably mounted on the wire winding machine frame, a rotating worktable being provided on one side of the wire winding machine frame, and a core tube being provided on the rotating worktable;
[0009] The lifting trolley includes a frame, a redirecting pulley, a swing seat, and a linear motion mechanism. The redirecting pulley and the swing seat are respectively movably mounted on the frame.
[0010] The prestressed steel wire on the winding machine frame passes sequentially through the redirecting pulley and the swing seat, and is wound onto the tube core;
[0011] One end of the linear motion mechanism is connected to the vehicle frame, and the other end is connected to the swing seat;
[0012] An anchor block is provided at the upper part of the tube core, and the slot of the anchor block is used to place the prestressed steel wire.
[0013] The linear motion mechanism is a cylinder, a hydraulic cylinder, or a linear actuator.
[0014] The lower part of the tube core is provided with an initial anchoring block.
[0015] The swing seat includes a seat body, one end of which is hinged to the frame, and the other end is provided with two guide wheels, through which the prestressed steel wire passes.
[0016] The top and bottom of the winding machine frame are respectively equipped with an upper sprocket and a lower sprocket, and lifting chains are wound around the upper sprocket and the lower sprocket.
[0017] One end of the lifting chain is connected to the top of the frame, and the other end is connected to the bottom of the frame.
[0018] It also includes a motor that drives a main sprocket, which is connected to a slave sprocket via a chain.
[0019] The slave sprocket drives the lower sprocket to move synchronously via a connecting shaft.
[0020] The winding machine frame is equipped with a platform, and the platform is surrounded by a fence.
[0021] In operation, the prestressed steel wire is first manually fixed to the lower part of the core tube. Then, a rotating worktable drives the core tube to rotate, generating tension in the prestressed steel wire. After activation, the prestressed steel wire is evenly wound onto the surface of the core tube according to the designed pitch. The prestressed steel wire is wound onto the core tube surface after its direction is changed by a redirecting pulley.
[0022] After the lifting trolley rises at a constant speed, it approaches the anchor block at the top of the core tube. The wire winding machine then automatically slows down and begins semi-stressed wire winding, slowly approaching the slot of the anchor block. Simultaneously, the linear motion mechanism drives a fine-tuning mechanism to ensure the prestressed steel wire is aligned with the slot of the anchor block.
[0023] This invention is easy to process and improves safety. Attached Figure Description

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0034] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] This utility model is as follows Figure 1-2 As shown, the adjustable wire winding machine lifting structure includes a lifting trolley 1, which is movably mounted on the wire winding machine frame 2. A rotating worktable 3 is provided on one side of the wire winding machine frame 2, and a core tube 4 is provided on the rotating worktable.
[0037] The lifting trolley 1 includes a frame 11, a redirecting pulley 12, a swing seat 13, and a linear motion mechanism 14. The redirecting pulley 12 and the swing seat 13 are respectively movably mounted on the frame 11.
[0038] The prestressed steel wire 5 on the winding machine frame 2 passes sequentially through the redirecting pulley 12 and the swing seat 13, and is wound onto the core tube 4; as shown Figure 2 As shown, the arrows indicate the direction of movement of the prestressed steel wires.
[0039] One end of the linear motion mechanism 14 is connected to the frame 11, and the other end is connected to the swing seat 13;
[0040] An anchor block 6 is provided on the upper part of the tube core, and the slot 60 of the anchor block is used to place the prestressed steel wire 5.
[0041] In operation, the prestressed steel wire is first manually fixed to the lower part of the core tube (i.e., manually tapped into the slot of the initial anchor block); secondly, the rotating worktable drives the core tube to rotate, so that the prestressed steel wire generates tension. After the linkage is started (i.e., the rotating worktable and the lifting trolley move synchronously), the prestressed steel wire is evenly wound onto the surface of the core tube according to the designed pitch.
[0042] In this process, the prestressed steel wire is redirected by a pulley and then wound onto the surface of the tube core.
[0043] like Figure 4 As shown, after the lifting trolley rises at a constant speed, it approaches the anchoring block at the top of the core tube. The wire winding machine then automatically slows down and performs semi-stressed wire winding, slowly approaching the slot of the anchoring block. Simultaneously, under the action of the linear motion mechanism, a fine-tuning mechanism is activated to ensure that the prestressed steel wire is aligned with the slot of the anchoring block. The rotating worktable driving the core tube's rotation is a conventional technique and will not be elaborated upon in this case.
[0044] The linear motion mechanism 14 can be a pneumatic cylinder, hydraulic cylinder, or linear actuator. It can be selected and configured according to actual needs; in application, it is not limited to these mechanisms.
[0045] The lower part of the core 4 is provided with an initial anchoring block.
[0046] Anchor block 6 has the same structure as the initial anchor block. The initial anchor block is installed at the bottom of the core 102 and is manually hammered in without stress.
[0047] When the wire winding is almost finished and the half-stress is reached, the anchor block 6 at the top of the core is manually tapped into the groove of the anchor block.
[0048] The swing seat includes a seat body 131, one end of which is hinged to the frame, and the other end is provided with two guide wheels, through which the prestressed steel wire passes.
[0049] Two guide wheels facilitate the passage of prestressed steel wires, and the swing seat is hinged, which facilitates fine-tuning under the drive of the linear motion mechanism.
[0050] The top and bottom of the winding machine frame are respectively provided with an upper sprocket 71 and a lower sprocket 72, and lifting chains 73 are wound around the upper and lower sprockets.
[0051] One end of the lifting chain is connected to the top of the frame, and the other end is connected to the bottom of the frame.
[0052] The lifting trolley moves up and down via a lifting chain, making it easy to operate.
[0053] It also includes a motor 74, which drives a main sprocket, the main sprocket being connected to a slave sprocket via a chain.
[0054] The slave sprocket drives the lower sprocket to move synchronously via a connecting shaft.
[0055] The motor drives the sprocket, which in turn drives the lifting chain.
[0056] The winding machine frame is equipped with a platform 81, and the platform is surrounded by a fence 82.
[0057] A platform is set up to facilitate observation and operation by staff; a fence is installed to improve personal safety. In application, the platform can be rotatably mounted on the winding machine frame for easy position adjustment.
