[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 - 5 The present invention provides a steel bar torque device for mechanical connection of steel bars, including a carrying work vehicle 6 for movement, a control component for personnel operation is fixedly connected to the top surface of the carrying work vehicle 6, a three-phase asynchronous motor 3 is arranged below the control component, the three-phase asynchronous motor 3 is fixedly connected to the carrying work vehicle 6, and the output shaft of the three-phase asynchronous motor 3 is connected to a torque wrench 1 for clamping the steel bars through a transmission component; the control component is electrically connected to the three-phase asynchronous motor 3.

[0030] The torque wrench 1 is a tool used to precisely control the tightening torque of bolts or nuts, ensuring that the fasteners reach the preset torque value during installation and avoiding equipment damage or safety hazards caused by over-tightening or under-tightening.

[0031] The types of torque wrench 1 are divided into: mechanical (preset type) torque wrench, digital display torque wrench, hydraulic torque wrench, dial torque wrench, etc.

[0032] Principle of mechanical (preset type) torque wrench: The torque value is preset by rotating the handle. When the applied torque reaches the set value, the internal mechanical structure (such as a spring or lever) will trigger a "click" sound or a tactile feedback to prompt to stop applying force. Features: Simple structure, durable, moderate price, suitable for general industrial scenarios.

[0033] Principle of digital display torque wrench: The torque value is displayed in real time through an electronic sensor, and the target value can be set and an audible and visual alarm can be issued. Features: High precision (±1%), data can be recorded, suitable for precision assembly or quality inspection processes.

[0034] Principle of hydraulic torque wrench: Utilize the hydraulic system to amplify the torque, suitable for ultra-large torque requirements (such as wind power, bridge engineering). Features: Large output torque (up to tens of thousands of Newton-meters), but large volume, need to be used in conjunction with a hydraulic pump.

[0035] Principle of dial torque wrench: The torque value is directly read through the dial pointer without presetting. Features: Intuitive and easy to read, but requires manual monitoring, suitable for small batch operations.

[0036] The three-phase asynchronous motor 3 is one of the most widely used types of motors in the industrial field, with a simple structure, high reliability and low maintenance cost.

[0037] The three-phase asynchronous motor 3 of the present invention drives the torque wrench 1 to act through the transmission component, enabling the torque wrench 1 to precisely tighten the straight thread sleeve, effectively ensuring the strength and stability of the connection joint.

[0038] The present invention is reasonably designed and easy to operate, not only greatly reducing the investment in labor costs, but also effectively improving the construction efficiency; and through the control component, the safety during the operation process is effectively ensured.

[0039] For a further optimized solution, the carrier work vehicle 6 includes a chassis, and a plurality of wheels with self-locking are installed at the bottom of the chassis. The chassis can be moved to the designated position through the wheels, and through the self-locking of the wheels, the movement of the wheels during the working process can be effectively avoided.

[0040] In a further optimized solution, the control component includes a personnel operating table 4 fixedly connected to the top surface of the chassis, and a safety starter 5 is installed at one end of the personnel operating table 4 facing the torque wrench 1, and the safety starter 5 is electrically connected to the three-phase asynchronous motor 3. When a worker sits on the personnel operating table 4, it is convenient to control the action of the three-phase asynchronous motor 3 through the safety starter 5.

[0041] In a further optimized solution, the transmission assembly includes a fork-shaped connecting rod 7 drivingly connected to the output shaft of the three-phase asynchronous motor 3, a driving connecting rod 2 is installed at one end of the fork-shaped connecting rod 7 away from the three-phase asynchronous motor 3, and the torque wrench 1 is installed on the end of the driving connecting rod 2 away from the fork-shaped connecting rod 7. The fork-shaped connecting rod 7 and the driving connecting rod 2 can effectively drive the torque wrench 1 to rotate through the three-phase asynchronous motor 3, so that the torque wrench 1 can effectively tighten the straight threaded sleeve mechanically connected to the steel bar.

[0042] The fork link 7 is a mechanical transmission component, commonly found in mechanisms that need to transmit power or connect multiple moving parts. Its name comes from its bifurcated geometry, usually with one or both ends in a "Y" or "U" shape to achieve special motion transmission or spatial layout requirements.

[0043] The bifurcated design of the fork-shaped link 7 can connect multiple moving parts at the same time, reducing the number of parts; and the bifurcated design of the fork-shaped link 7 can effectively disperse the load, reduce stress concentration, and improve durability.

[0044] The fork-shaped connecting rod 7 allows a larger swing angle or space for avoidance; and the forked end of the fork-shaped connecting rod 7 can be embedded in a bearing or a bushing to reduce friction loss.

[0045] The driving connecting rod 2 is a key component in the mechanical system that converts the rotation or linear motion of the power source into a specific motion form. The driving connecting rod 2 receives external power input in the mechanism and drives the active components of other connecting rods to move.

[0046] The three-phase asynchronous motor 3 drives the driving connecting rod 2 to rotate through the fork-shaped connecting rod 7, and the driving connecting rod 2 drives the torque wrench 1 to rotate, which not only enables accurate tightening, but also greatly shortens the working hours and effectively improves the construction efficiency.

[0047] In a further optimized solution, a threaded hole 8 is provided at one end of the driving connecting rod 2 facing the fork-shaped connecting rod 7, a bolt is threadedly connected in the threaded hole 8, and the bolt is threadedly connected to the end of the fork-shaped connecting rod 7 facing the driving connecting rod 2. The driving connecting rod 2 and the fork-shaped connecting rod 7 can not only be effectively connected for transmission, but also facilitate replacement of the driving connecting rod 2.

[0048] In a further optimized solution, the torque wrench 1 is mounted on the driving connecting rod 2 through an expansion bolt 9 at one end of the driving connecting rod 2 facing the torque wrench 1. The expansion bolt 9 facilitates the installation and removal of the torque wrench 1.

[0049] For a further optimized solution, the central axis of the fork-shaped connecting rod 7 and the central axis of the output shaft of the three-phase asynchronous motor 3 are on the same central axis, enabling the three-phase asynchronous motor 3 to effectively drive the fork-shaped connecting rod 7 to rotate.

[0050] For a further optimized solution, the safety start / stop device 5 includes a start button, a pause button, and an emergency button. The start button is used to control the start of the three-phase asynchronous motor 3, the pause button is used to control the stop of the three-phase asynchronous motor 3, and the emergency button is used to quickly cut off the power supply of the three-phase asynchronous motor 3 in case of an emergency.

[0051] For a further optimized solution, the start button and the pause button are arranged adjacent to each other and installed on the side of the personnel operation platform 4 facing the torque wrench 1. By arranging the start button and the pause button adjacent to each other, it is convenient for the staff to operate.

[0052] For a further optimized solution, the emergency button is separately installed on the top surface of the side of the personnel operation platform 4 facing the torque wrench 1. By setting the emergency button separately, when an emergency occurs, it is convenient for the staff to quickly and effectively press the emergency button, which can effectively prevent accidents from happening and ensure the safety of the operators.

[0053] Working process: The chassis can be moved to the designated position through the wheels, and through the self-locking of the wheels, the movement of the wheels during the working process can be effectively avoided. Clamp one end of the steel bar without the connecting sleeve on the torque wrench 1, adjust the torque value as required, and then press the start button. The three-phase asynchronous motor 3 drives the fork-shaped connecting rod 7 to rotate, the fork-shaped connecting rod 7 drives the driving connecting rod 2 to rotate, and the driving connecting rod 2 transmits the rotational force to the torque wrench 1 for operation through the torque wrench 1.
