Description

Technical Field

[0001] This invention relates to the field of electric actuators, and in particular to an electric strander. Background Technology

[0002] During transportation, steel coils need to be secured to prevent displacement and tipping, thus ensuring transportation safety. In practice, workers commonly use a method of binding by twisting two bundles of fine steel wire together to form a stranded bundle. The specific operation process is as follows: Each binding unit is based on two bundles of fine steel wire. First, the two bundles of fine steel wire are wrapped around the steel coil to complete the pre-winding. Then, a pry bar is manually used to twist the twisted section of the two bundles of steel wire. During the twisting process, the steel wire bundle is tightened simultaneously, thereby effectively securing the steel coil. Figure 8 As shown; typically, a steel coil requires four sets of such stranded steel wire bundles to circumferentially fix the coil from different directions, ensuring the stability of the binding, such as... Figure 9 As shown.

[0003] Currently, the twisting of stranded steel wire bundles for steel coil binding relies entirely on manual operation, which suffers from numerous technical defects and efficiency bottlenecks. Firstly, manual twisting requires the alternating use of two levers: due to the limited space between the vertically placed steel coil and the transport vehicle, a single lever inserted between two bundles of wire can only achieve a 90° twist, failing to complete large-angle continuous twisting. A second lever must be inserted and the 90° twisting action repeated. This not only involves cumbersome procedures and high labor intensity, but also requires repeated alternating operations for twisting a single bundle of wire, resulting in low efficiency and wasted human resources. Secondly, manual twisting is highly dependent on the operator's physical strength; prolonged operation easily leads to fatigue, resulting in uneven tension and structural instability in the twisted wire bundles (e.g., ...). Figure 9 As shown in the figure, this directly affects the firmness of the steel coil binding, increasing the safety risk of the steel coil shifting or tipping over during transportation.

[0004] In response to the problems existing in the above-mentioned manual twisting operation, there is an urgent need for a device that can replace manual operation to effectively improve the efficiency of steel coil binding, ensure binding quality, reduce the labor intensity of operators, and meet the actual operation needs. Summary of the Invention

[0005] To address the above problems, this invention proposes an electric stranding device, the technical solution of which is as follows: An electric stranding device includes a mounting housing, a rotor, and a power unit; the rotor is rotatably mounted inside the mounting housing and driven to rotate by the power unit; the rotor has a non-closed opening, and a strip connected to the rotor is provided in the non-closed opening, the strip dividing the non-closed opening into left and right parts.

[0006] Furthermore, the rotor is equipped with a plurality of rolling pins distributed circumferentially, and the mounting shell is fixedly equipped with a limiting groove that cooperates with the rolling pins, with the lower end of the rolling pin embedded in the limiting groove.

[0007] Furthermore, the rotor is provided with a groove extending circumferentially thereon, and a protrusion that mates with the groove is provided at a corresponding position inside the mounting housing, the protrusion being embedded in the groove.

[0008] Furthermore, it also includes a housing, which is fixedly connected to the mounting shell; the power unit is disposed inside the housing, and the output end of the power unit drives the rotor to rotate through a transmission assembly.

[0009] Furthermore, the rotor has circumferential teeth; the transmission assembly includes an input gear and at least two output gears rotatably mounted on the mounting housing; the input gear is connected to the output end of the power unit; the output gear is connected to the input gear via a transition gear and intermittently meshes with the teeth of the rotor; when the rotor rotates to the point where one of the output gears is about to disengage from the teeth, at least one of the remaining output gears remains engaged with the teeth.

[0010] Furthermore, the housing has a gun-type structure, including a gun-type grip and a main body housing. The gun-type grip integrates a switch and control circuit, and a battery compartment is provided at the bottom of the gun-type grip, in which a battery is installed. The main body housing houses the power unit.

[0011] Furthermore, the insert and the rotor are configured as an integral structure or a detachable connection.

[0012] Furthermore, the outermost end of the insert is provided with a limiting head.

[0013] Furthermore, the top of the limiting head is provided with an inclined plane.

[0014] Furthermore, the mounting housing is also provided with a handle.

[0015] Furthermore, the mounting housing is also provided with a support rod, which is supported on the vehicle body or other support surface during operation.

[0016] Because the present invention adopts the above-described technical solution, the present invention has the following advantages: 1. This invention uses an electric drive to replace manual pry bar to complete the twisting operation of two bundles of steel wires. The power unit drives the rotor to rotate continuously through the transmission component, realizing the continuous automatic twisting of the steel wire bundles. This completely solves the problem of low efficiency caused by alternating operation of two pry bars, significantly improves the efficiency of twisting operation, and greatly reduces the labor intensity of operators.

[0017] 2. This invention divides the rotor into left and right parts by setting inserts in the non-closed opening of the rotor. Two bundles of steel wires are inserted from the left and right sides respectively. When the rotor rotates, the inserts rotate synchronously and apply uniform torque to the two bundles of steel wires to achieve a consistent twisting effect. This effectively solves the problems of uneven tightness and unstable structure in manual twisting and improves the firmness of steel coil binding.

[0018] 3. The outermost end of the insert bar of the present invention is provided with a limiting head, which can prevent the inserted steel wire from coming out during the twisting process. The top sloping plane design makes it easy for operators to quickly guide the steel wire into the non-closed opening, improving the convenience of operation.

[0019] 4. The housing of this invention adopts a gun-type structure, which is convenient and flexible for hand-held operation. The battery can be plugged in and replaced in the battery compartment, making it suitable for on-site operation environments without power. The housing is equipped with a handle and a support rod. During operation, the support rod abuts against the vehicle body or other support surface to provide reaction force, further reducing the burden on the operator's hands. Attached Figure Description

[0033] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] In the description of this invention, it should be noted that the terms "upper", "lower", "in", "out", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limiting this invention. Example

[0035] like Figures 1-2 As shown, an electric stranding device includes a mounting housing 1 and a rotor 2. The rotor 2 is rotatably mounted on the mounting housing 1. The rotor 2 has a non-closed opening, and an insert 3 connected to the rotor 2 is provided in the non-closed opening, dividing the non-closed opening into left and right parts. During operation, two bundles of steel wires are inserted from the left and right sides of the insert 3 respectively. After the power unit is started, the rotor 2 rotates, driving the insert 3 to rotate synchronously, applying a continuous torque to the two bundles of steel wires, thereby achieving the twisting of the two bundles of steel wires.

[0036] As a specific embodiment where the rotor 2 is rotatably mounted on the mounting housing 1, such as Figures 3-5As shown, the mounting housing 1 consists of a cover plate 101 and a base plate 102 fixedly connected together. A plurality of rolling pins 202 distributed circumferentially are mounted on the bottom end of the rotor 2. A limiting groove 1021 that mates with the rolling pins 202 is fixedly mounted on the base plate 102, with the lower end of the rolling pin 202 embedded in the limiting groove 1021. The cooperation between the limiting groove 1021 and the rolling pins 202 guides the rotor 2 to rotate along a predetermined trajectory and also provides support for the rotor 2, preventing deflection or vibration during high-speed rotation and ensuring the stability of the equipment operation.

[0037] As another embodiment where the rotor 2 is rotatably mounted on the mounting shell 1, a groove extending circumferentially can be provided at the bottom of the rotor 2, and a protrusion that cooperates with the groove can be provided at a corresponding position inside the mounting shell 1. During assembly, the protrusion is embedded in the groove, allowing the rotor 2 to rotate freely relative to the mounting shell 1, while providing support and limiting the rotor 2 to prevent it from shifting or deflecting during rotation. The structure is simple and compact, and easy to process and assemble.

[0038] This electric stranding device also includes a housing 10, which is fixedly connected to a mounting shell 1; the rotor 2 is driven to rotate by a power unit, which is housed within the housing 10. Specifically, as... Figures 1-2 As shown, the housing 10 adopts a conventional gun-type structure in the art, including a gun-type grip and a main body housing. The gun-type grip is used for handheld operation and integrates switches and control circuits. A battery compartment is provided at the bottom, in which a battery is installed to provide power to the power unit. The main body housing houses the power unit, and the output end of the power unit drives the rotor 2 to rotate through a transmission component.

[0039] As a specific implementation of rotor 2 drive, such as Figures 3-5 As shown, the rotor 2 has circumferentially arranged gear teeth 201. The transmission assembly includes an input gear 7, a transition gear 8, and an output gear 9 rotatably mounted on the mounting housing 1. The input gear 7 is connected to the output end of the power unit, and the output gear 9 intermittently meshes with the gear teeth 201 of the rotor 2. The transition gear 8 meshes with both the input gear 7 and the output gear 9. The torque of the power unit is transmitted through the three stages of the input gear 7, transition gear 8, and output gear 9 to drive the rotor 2 to rotate. This design has two purposes: First, by rationally designing the gear ratios, the output torque can be increased while appropriately reducing the rotational speed, thus meeting the torque requirements for wire twisting. Second, when the rotor 2's diameter and opening are enlarged to accommodate thicker wire bundles, the span between each pair of output gears 9 can be increased by rationally increasing the number of transition gears 8, ensuring that the rotor 2 is always driven by at least one output gear 9 during rotation, thereby achieving continuous rotation.

[0040] In order to enable the rotor 2 to rotate continuously when passing through the non-closed opening during rotation, there are two output gears 9. When the rotor 2 rotates to the point where one output gear 9 is about to disengage from the gear tooth 201, the other output gear 9 remains engaged with the gear tooth 201. Thus, through the alternating relay drive of the two output gears 9 at the non-closed opening, the rotor 2 is always subjected to the driving torque and rotates continuously.

[0041] As one specific implementation method for installing insert 3, such as Figure 7 As shown, the insert 3 can be integrated into the rotor 2 to improve the connection strength between the insert 3 and the rotor 2.

[0042] As another specific implementation of the insertion strip 3 installation, the insertion strip 3 can also be connected to the rotor 2 through a detachable design, which facilitates the replacement and maintenance of the insertion strip 3 after wear. Specifically, the insertion strip 3 has an insertion block at its tail end, and the rotor 2 has a slot that mates with the insertion block; the electric strander also has a fixing plate 4. After the insertion block is inserted into the slot, the fixing plate 4 is fixedly connected to the insertion block and the rotor 2 by screws to ensure the reliability of the connection.

[0043] As a specific implementation of the insert type 3, such as Figure 3 and Figure 6 As shown, the outermost end of the insert 3 is provided with a limiting head 301, which can limit the steel wire entering the non-closed opening to prevent the steel wire from coming out of the non-closed opening during the twisting process and to ensure the continuity of twisting. The top of the limiting head 301 is provided with a sloping plane, which makes it convenient for the steel wire to slide into the non-closed opening along the sloping plane, improving the ease of operation.

[0044] As a specific implementation of this embodiment, the mounting shell 1 is also provided with a handle 5, which makes it convenient for operators to hold the equipment stably during work and improves operability.

[0045] As a specific implementation of this embodiment, the mounting shell 1 is also provided with a support rod 6. When working, the support rod 6 is supported on the vehicle body or other support surface to provide reverse support force for the equipment and reduce the burden on the operator's hands.

[0046] The working principle of this embodiment is as follows: In use, the operator holds the gun-shaped handle of the housing 10, aligns the front end of the mounting housing 1 with the twisted sections of the two bundles of steel wire already wrapped around the steel coils, and inserts the insert bar along the gap between the two bundles of steel wire, so that the two bundles of steel wire are respectively placed into the left and right spaces of the non-closed opening of the rotor 2. The support rod 6 is supported on the vehicle body. Pressing the switch on the gun-shaped handle starts the power unit. The output end transmits torque to the rotor 2 through the input gear 7, the transition gear 8, and the output gear 9. The rotation of the rotor 2 drives the insert bar 3 to continuously apply torsional force to the two bundles of steel wire, and the two bundles of steel wire are then twisted and gradually tightened. The actual working effect is as follows: Figures 10-11 As shown; Figure 12 The image shows a bundle of steel wires twisted using an electric strander, compared to... Figure 9 The manually twisted wire bundle shown is more uniform in tightness and more stable in structure than the wire bundle twisted by the electric strander, which can improve the firmness of the steel coil binding.

[0047] Once the twisting reaches the required tightness, release the switch, rotor 2 stops rotating, remove the equipment, and complete the twisting and binding operation of a set of steel wire bundles.
