Technical Field

[0001] The utility model belongs to the field of pipes, and in particular relates to a steel pipe straightening device. Background Art

[0002] Steel pipe is a common tubular material, widely used in various fields. During the use of steel pipe, due to external impact or collision during assembly and disassembly, some steel pipes will bend, affecting their use. In order to ensure the use function of the steel pipe, the bent steel pipe needs to be straightened.

[0003] At present, the straightening of steel pipes mainly relies on special straightening machines, which need to be connected to electricity and operated by special personnel, and a specific work site is set up. For construction projects, the use sites of domestic and foreign protective frames and support frame steel pipes are relatively scattered. It is time-consuming and laborious to collect bent steel pipes to a specific work site for straightening. In addition, the special straightening machine is expensive, and the maintenance and use costs are high. In addition, the operation of the straightening machine requires technology and experience, and is highly complex. Professional training is required to operate it proficiently. In addition, the operation of complex machinery also has safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] As shown in the figure, the utility model provides a steel pipe straightening device, which includes a bracket 1 placed on the ground, a main beam 2 with one end passing through the bracket 1 and tilted, a positioning card 3 is fixed to the tilted end of the main beam 2, and an arc-shaped notch 4 is opened on the positioning card 3 for the end of the steel pipe 6 to pass through, and a roller 5 is provided on the bracket 1 above the main beam 2, and the middle of the roller 5 is recessed inward to form an arc-shaped groove for scaffolding the steel pipe 6. In specific applications, since the main beam 2 passes through the bracket 1, the bracket 1 is placed on the ground, and the bracket 1 and the main beam 2 provide stable support for the entire device, the main beam 2 is fixed with a positioning card 3, and the positioning card 3 is opened with an arc-shaped notch 4, and the roller 5 arranged above the main beam 2 ensures that the steel pipe 6 passes through accurately and is adjusted, and ensures that the position of the steel pipe 6 in the device is correct.

[0024] The bracket 1 includes a vertical support frame 101, a horizontal support leg 102, a horizontal support frame 103 and a roller shaft 104. The horizontal support leg 102 can be, for example, a square steel plate with a certain thickness. The vertical support frame 101 is two short rods. The two vertical support frames 101 are fixed on the horizontal support leg 102 in an "eight" shape. The material of the vertical support frame 101 can be, for example, steel bars. The horizontal support frame 103 of the main beam 2 is connected between the two vertical support frames 101. Preferably, the horizontal support frame 103 is fixed to the middle of the vertical support frame 101. The roller shaft 104 connects the end of the vertical support frame 101 away from the horizontal support leg 102. The main beam 2 is placed in the enclosed area formed by the vertical support frame 101 and the horizontal support frame 103 and is fixedly connected to the horizontal support frame 103, for example, by welding. In specific applications, since the two vertical support frames 101 are fixed in an eight-shaped shape on the horizontal support legs 102, this provides good structural stability for the device; since the horizontal support frame 103 of the main beam 2 is connected between the two vertical support frames 101, the main beam 2 is placed in the enclosed area formed by the vertical support frames 101 and the horizontal support frames 103 and is fixedly connected to the horizontal support frames 103, in this way, the horizontal support frame 103 of the main beam 2 can effectively support the main beam 2 and prevent the main beam 2 from shaking.

[0025] The main beam 2 includes a tubular body 201. One end of the tubular body 201 is provided with an end reinforcement sealing plate 202 for sealing the port of the tubular body 201, and the other end is provided with an end reinforcement angle steel 203. The end reinforcement angle steel 203 is used to increase the contact area between the main beam 2 and the ground, improve the friction between the main beam 2 and the ground, enhance the stability and anti-slip ability of the device, and strengthen the stability of the main beam 2. The tubular body 201 can be, for example, a large-diameter steel pipe 6, and the diameter can be, for example, 15-40cm.

[0026] The positioning card 3 includes a reinforcing lining plate 301 connected to the end of the main beam 2 and an open reinforcing rib 302 fixed on the reinforcing lining plate 301. The reinforcing lining plate 301 is vertically connected to the main beam 2. The open reinforcing rib 302 is in a semicircular opening shape, including an arc portion 3021 and a straight rod portion 3022 connected to the arc portion 3021. The open reinforcing rib 302 can be, for example, a steel bar, and the arc portion 3021 and the straight rod portion 3022 can be, for example, integrally formed.

[0027] The arc-shaped notch 4 includes an upper arc-shaped notch 401 opened on the reinforcing lining plate 301 and a lower arc-shaped notch 402 located below the upper arc-shaped notch 401. The diameter of the circle where the arc-shaped edge of the lower arc-shaped notch 402 is located is consistent with the diameter of the main beam 2. The arc-shaped edge of the lower arc-shaped notch 402 is connected to the outer surface of the main beam 2. The upper arc-shaped notch 401 is higher than the main beam 2. The shape of the upper arc-shaped notch 401 is consistent with the shape of the arc-shaped portion 3021 of the opening reinforcement rib 302. The arc-shaped portion 3021 of the opening reinforcement rib 302 is connected to the reinforcing lining plate 301 along the upper arc-shaped notch 401. Preferably, the diameter of the circle where the arc-shaped edge of the upper arc-shaped notch 401 is located is not less than the diameter of the steel pipe 6 to be straightened. Preferably, the reinforcing lining plate 301 is flush with the end reinforcement cover plate 202 of the main beam 2.

[0028] The roller 5 is saddle-shaped, with high sides and low middle. The central axis of the roller is perforated and mounted on the roller shaft 104. The roller 5 rotates around the roller shaft 104. The space formed by the upper arc notch 401 and the arc groove of the roller 5 partially overlap, so that after the bent steel pipe 6 is mounted on the roller 5, when the steel pipe 6 is pushed toward the arc notch 4, the end of the steel pipe 6 can pass through the upper arc notch 401. In specific applications, since the roller 5 is saddle-shaped, with high sides and low middle, it provides stable support for the bent steel pipe 6 and effectively supports the weight of the steel pipe 6 during rolling; since the roller 5 rotates around the roller shaft 104, the steel pipe 6 rolls smoothly on the roller 5; since the upper arc notch 401 and the space formed by the arc groove of the roller 5 partially overlap, it is ensured that the steel pipe 6 will not be obstructed or stuck during rolling, and the smooth movement of the steel pipe 6 is guaranteed.

[0029] like Figure 5 and 6 As shown, a method for using a steel pipe straightening device of the utility model:

[0030] (1) Place the device on site, with the horizontal support legs 102 and the end reinforcement angle steel 203 placed on the ground, one end of the end reinforcement cover plate 202 of the main beam 2 tilted up, and the bent steel pipe 6 stacked next to the device.

[0031] (2) Pick up a bent steel pipe 6 and place the bent portion between the upper arc-shaped notch 401 of the positioning card 3 and the arc-shaped groove of the roller 5. The front portion of the steel pipe 6 passes through the upper arc-shaped notch 401 at the opening of the positioning card 3 and is pressed by the positioning card 3. The bent portion of the steel pipe 6 is supported in the arc-shaped groove of the roller 5.

[0032] (3) The steel pipe 6 behind the roller 5 is pressed to be straightened, and the roller 5 can be rotated forward and backward to move the steel pipe 6 to keep the bending position of the steel pipe 6 always between the positioning card 3 and the roller 5, so as to adjust the steel pipe 6 to be straight.

[0033] (4) Arrange and stack the straightened steel pipes 6 and transport them to the nearest location for use.
