Description
Technical Field
The invention belongs to the field of electric tools and relates to an electric tool for quickly mounting a steel bar straight threaded sleeve.
Background
Along with the great environment of continuous progress of modern technology, the requirements on the connection strength of the reinforcing steel bars are also increasing in the field of construction. At present, the steel bar straight threaded sleeve is used for connection, which meets the specifications, is the most mature and is the most widely used. However, because the steel bars are arranged in large density, the distance between the left adjacent steel bars and the right adjacent steel bars is small, and the length of the connected steel bars is increased, the existing electric tool cannot be used at present, and only a pipe wrench can be used for connection and installation manually. Because the number of the steel bar connections is huge, the resistance is larger during the rotary installation, and the steel bar joints are also exactly installed at the center of the straight threaded sleeve, so that the connection installation efficiency is very low. The invention adopts an open type rotary disc structure, can easily clamp the electric tool on the straight threaded sleeve, is quickly rotatably installed, can accumulate the number of rotation turns, automatically stops after the set number of turns is reached, ensures that the steel bar joint is positioned at the center of the straight threaded sleeve, and greatly improves the production efficiency. Some pile foundation reinforcing steel bars and vertically connected reinforcing steel bars are required to be hoisted by using a hoisting device in construction, and after the electric tool is used, a large amount of mechanical bench cost can be saved, and the economic benefit is very good.
Disclosure of Invention
The invention aims to greatly improve the installation efficiency of a steel bar straight threaded sleeve and provides a brand new electric installation tool.
To achieve the above object, the present invention includes: the device comprises a shell, a main rotating disc, a ratchet block a, a ratchet block b, a gear a, a gear b, peripheral gear teeth of the main rotating disc, an annular limiting device, a limiting ring, a driving gear, an inductive switch and a motor. The main rotary disk is provided with a U-shaped opening, ratchet blocks a and b are arranged on two sides of the U-shaped opening, gear teeth and an annular limiting device are arranged on the periphery of the main rotary disk, a limiting ring is fixed on a shell, a motor is arranged on the shell, a driving gear is connected with the motor and outputs torque, the driving gear is meshed with a gear a and a gear b simultaneously, the gear a and the gear b are meshed with the gear teeth on the periphery of the main rotary disk simultaneously, and the limiting ring fixed on the shell is in friction contact with the annular limiting device on the periphery of the main rotary disk, so that the main rotary disk freely rotates within the constraint range of the limiting ring, an induction switch is arranged on the shell, and a counting control function is provided in a control circuit. The main rotating disc annular limiting device is formed by distributing a plurality of bearings in an annular mode, and an annular ring serving as the annular limiting device can be made of wear-resistant materials.
The U-shaped opening of the main rotating disk is clamped on the steel bar straight threaded sleeve, the ratchet blocks a and b at two sides of the U-shaped opening are abutted against the straight threaded sleeve under the action of the spring, and when the main rotating disk rotates clockwise, the ratchet blocks a and b lock the straight threaded sleeve to rotate simultaneously with the main rotating disk, so that the sleeve is installed in place. When the main rotating disk rotates anticlockwise, the ratchet block a and the ratchet block b have no locking effect on the straight threaded sleeve, meanwhile, the U-shaped opening of the main rotating disk is forced to be away from the straight threaded sleeve, and when the U-shaped opening rotates to be aligned with the opening on the shell, the U-shaped opening is pulled away from the straight threaded sleeve, so that the installation is completed.
Under the action of the spring, the ratchet block a has a counterclockwise torque, and the ratchet block b has a clockwise torque.
The distance between the gear a and the gear b and two meshing positions of the gear teeth on the periphery of the main rotating disk is larger than the size of the U-shaped opening on the main rotating disk. When the main rotary disk rotates, the U-shaped opening on the main rotary disk rotates to the position of the gear b, the gear b cannot be meshed with the peripheral gear teeth of the main rotary disk, the gear a is singly meshed with the peripheral gear teeth of the main rotary disk, when the U-shaped opening on the main rotary disk rotates to the position of the gear a, the gear b is meshed with the peripheral gear teeth of the main rotary disk, torque is transmitted, and at least one gear of the gear a or the gear b is meshed with the peripheral gear teeth of the main rotary disk in the rotating process.

Detailed description of the preferred embodiments
The following is a specific embodiment of the present invention, and the present invention is further described with reference to the accompanying drawings, but the present invention is not limited to the embodiment.
The U-shaped opening 1 on the main rotary disk is clamped on the straight threaded sleeve 10 arranged on the steel bar, the ratchet blocks a2 and b16 on two sides are abutted against the steel bar straight threaded sleeve 10 under the action of the spring, and the torque balance rod 14 is abutted against the other steel bar adjacent to the right side and is used for counteracting the reverse torque generated when the steel bar straight threaded sleeve 10 is arranged. Starting a motor 12 to drive a gear 4 to start rotating, driving a gear a5 and a gear b6 meshed with the gear a5 to rotate simultaneously, driving a gear 7 on the periphery of a main rotating disk to enable the main rotating disk 3 to rotate under the constraint of a limiting ring 11 on an annular limiting device 8 and a shell 9, enabling ratchet blocks a2 and ratchet blocks b16 arranged on two sides of a U-shaped opening 1 of the main rotating disk to rotate synchronously with the main rotating disk, tightly locking a reinforced bar straight thread sleeve 10 due to the locking effect of the ratchet blocks a2 and the ratchet blocks b16, enabling the sleeve to rotate together in the rotating direction of the main rotating disk 3, enabling a sensing switch 13 arranged on the shell 9 to sense once every time the main rotating disk 3 rotates a circle, and enabling the main rotating disk 3 to rotate to a set circle, the control circuit makes the main rotary disk 3 rotate a plurality of angles, when the main rotary disk U-shaped opening 1 rotates a plurality of angles of about 60 degrees, the circuit automatically stops the rotation of the motor 12, at the moment, the motor 12 is started to rotate reversely, meanwhile, the handle 15 is held by hands to pull outwards, when the main rotary disk U-shaped opening 1 rotates reversely, the ratchet block a2 and the ratchet block b16 also rotate in the direction opposite to the locking straight threaded sleeve 10, so that the locking state is separated, when the main rotary disk U-shaped opening 1 rotates back to about 60 degrees, the inductive switch 13 senses, the power supply of the motor 12 is disconnected, the main rotary disk U-shaped opening 1 rotates to the starting position, the U-shaped opening is pulled away from the straight threaded sleeve, the set rotation number is simultaneously reset to zero, and the electric tool returns to the working starting state. Such a workflow is completed and the next job is performed.
