Description

Technical Field

[0001] The utility model belongs to the technical field of correction devices, and in particular relates to a steel bar correction device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is generally circular, sometimes square with rounded corners. During construction, some bent rebars due to collisions during transportation, storage, and use need to be straightened. Rebars are generally straightened using a rebar straightening machine, but this equipment is large in size and has low flexibility when used on construction sites. It is not possible to straighten the rebar near the construction site, and the rebar needs to be carried a long distance, which is inconvenient. For this reason, we propose a small rebar correction device to meet the demand for local straightening of rebars. Utility Model Content

[0003] In response to the above problems, the purpose of the present invention is to provide a steel bar correction device, which has a relatively simple structure, a small size and is easy to carry, and a low cost. It can meet the needs of temporary steel bar straightening work on the construction site and is easy to produce and manually operate.

[0004] The top of the gear train is equipped with a gear that is connected with the gear of the gear train, and the gear train is equipped with a gear to turn the gear of the gear train to turn the gear of the gear train to the gear train, so that the gear train can be easily installed.

[0005] The beneficial effects of the present invention are as follows: the device can be lifted with one hand through the carrying handle, which is convenient for carrying and moving. When the device is in use, after the device is placed on the ground, the first hand wheel is turned to drive the first worm to rotate, and the transmission between the first worm and the first worm gear drives the screw to rotate, and the transmission between the screw and the transmission bracket drives the transmission bracket and the guide rod to rise, thereby driving the straightening wheel mounting frame and the straightening wheel located above to rise. At this time, one end of the bent steel bar can be filled between the upper and lower sets of straightening wheels from one end of the device, and then the first hand wheel is rotated in the opposite direction to make the upper and lower sets of straightening wheels approach each other to clamp the ends of the steel bar. At the same time, due to the self-locking function between the first worm gear and the first worm, the clamping function of the upper and lower sets of straightening wheels on the steel bar can be maintained, and then the second hand wheel can be turned to drive the straightening wheel below to rotate, and as the second hand wheel rotates, the second worm also moves accordingly. The second worm gear drives the second worm wheel to rotate, thereby driving the rotating shaft and the straightening wheel connected to it to rotate. When this rotating shaft rotates, the pulley on its outer side also rotates synchronously. The two adjacent rotating shafts rotate synchronously through the transmission between the pulleys and the belts. The friction force and the driving protrusion of the driving protrusion on the protrusion of the steel bar drive the steel bar to move between the upper and lower groups of multiple straightening wheels. The straightening wheels that are evenly arranged and on the same horizontal line are used to straighten the steel bars. Due to the high transmission efficiency between the second worm gear and the second worm wheel, the straightening wheel can be driven to rotate more labor-savingly, and the self-locking property between the two can be used to well control the rotation and locking of the straightening wheel. In summary, the structure of this device is relatively simple, the size is small and easy to carry, the cost is low, it can meet the needs of temporary steel bar straightening work on the construction site, and is convenient for production and manual operation.

[0006] To improve the stability of steel bar transportation:

[0007] As a further improvement of the above technical solution: a limiting protrusion is provided on the side of the straightening wheel, and a driving protrusion is also provided on the outer surface of the straightening wheel mounting frame.

[0008] The beneficial effects of this improvement are: the limiting protrusion is used to prevent the steel bars from deviating during transportation, and the sending protrusion can play a sending role on the protrusion on the steel bars, thereby improving the stability of steel bar transportation.

[0009] In order to drive the first and second worms to rotate:

[0010] As a further improvement of the above technical solution: the first worm wheel and the first worm are meshingly driven, and the second worm wheel and the second worm are meshingly driven.

[0011] The beneficial effect of this improvement is that the first worm wheel and the first worm are meshed for transmission, and the second worm wheel and the second worm are meshed for transmission, so that the first worm wheel and the second worm wheel can respectively drive the first worm and the second worm to rotate.

[0012] To improve the stability of steel bar transportation:

[0013] As a further improvement of the above technical solution: a pulley is provided on the outer side of the rotating shaft, and two adjacent sets of pulleys are connected by a belt.

[0014] The beneficial effect of this improvement is that the two adjacent rotating shafts rotate synchronously through the transmission between the pulleys and belts, so that the straightening wheels located below can rotate synchronously, thereby improving the stability of steel bar transportation.

[0015] To rotate the first and second worm gears:

[0016] As a further improvement of the above technical solution: one end of the first worm is connected to the first hand wheel, and one end of the second worm is connected to the second hand wheel.

[0017] The beneficial effect of this improvement is that the first worm can be rotated by the first hand wheel, and the second worm can be rotated by the second hand wheel, thereby driving the first worm wheel and the second worm wheel to rotate.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

When the device is in use, after the device is placed on the ground, the first hand wheel 11 is rotated to drive the first worm 10 to rotate, and the transmission between the first worm 10 and the first worm gear 8 drives the screw rod 7 to rotate, and the transmission between the screw rod 7 and the transmission bracket 5 drives the transmission bracket 5 together with the guide rod 4 to rise, thereby driving the straightening wheel mounting bracket 12 and the straightening wheel 13 located above to rise. At this time, one end of the bent steel bar can be filled between the upper and lower sets of straightening wheels 13 from one end of the device, and then the first hand wheel 11 is rotated in the opposite direction, so that the upper and lower sets of straightening wheels 13 are close to each other to clamp the end of the steel bar.
