[0011] The utility model has the following beneficial effects:

[0012] 1. The simple rack pipe straightener of the present application forms a channel by combining a lower mold and an upper mold, and the rack pipe is directly passed through the mold. The rear end bending part is placed in the lower mold, and the front end bending part is placed in the upper mold. Through the principle of leverage, downward pressure is applied to the rear end of the rack pipe to correct the rack pipe, and the structure is simple.

[0013] 2. The simple rack pipe straightener of the present application improves construction efficiency and is easy to operate. It can meet the needs of on-site correction of rack pipes of various calibers by changing the spacing between the upper mold and the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. 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.

[0019] As shown in the figure, a simple rack pipe straightener includes a bracket, an upper mold 6 and a lower mold 5. The upper mold 6 and the lower mold 5 are distributed front and back in the length direction of the bracket, and the upper mold 6 and the lower mold 5 are relatively distributed up and down in the height direction of the bracket, and a channel for the rack pipe to be corrected to pass through is formed between the upper mold 6 and the lower mold 5 in the height direction.

[0020] In the rack pipe correction operation, the rack pipe to be corrected is passed through the lower mold 5 and the upper mold 6, the rear end bent part is placed in the lower mold, and the front end bent part is placed in the upper mold 6. Through the lever principle, downward pressure is applied to the rear end of the rack pipe to correct the rack pipe.

[0021] The bottom end of the upper mold 6 and the top end of the lower mold 5 are both provided with pipe grooves, and the pipe grooves of the upper mold 6 and the lower mold 5 form a channel, and the axis of the channel is horizontal. By such an arrangement, it is more convenient for the pipe to be corrected to pass through the channel, which is convenient for operation.

[0022] The bracket includes a bottom transverse support rod 1, an oblique support rod 4, a vertical long support rod 2 and a vertical short support rod 3. Two bottom transverse support rods 1 are provided, and an oblique support rod 4 is provided directly above the bottom transverse support rod 1. The bottom transverse support rod 1 is connected to the higher end of the oblique support rod 4 through the vertical long support rod 2, and the bottom transverse support rod 1 is connected to the lower end of the oblique support rod 4 through the vertical short support rod 3. The upper mold 6 is installed on the bracket near the higher end of the oblique support rod 4, and the lower mold 5 is installed on the bracket near the lower end of the oblique support rod 4. The bottom transverse support rod 1, the oblique support rod 4, the vertical long support rod 2 and the vertical short support rod 3 can all be made of the rack pipe materials at the construction site, and the materials are convenient to obtain.

[0023] In actual application, when correcting large-diameter pipe racks, considering the insufficient stability of the bracket, which leads to the front end of the bracket tilting when correcting the large-diameter pipe rack, a counterweight can be added to the upper part of the bottom horizontal support rod 1 or the bracket can be directly and firmly welded to the nearby steel structure at the construction site.

[0024] The bracket also includes a mold support rod 8 for mounting the upper mold 6 and the lower mold 5, respectively, and the mold support rod 8 is mounted between the two oblique support rods 4. The mold support rod 8 is connected to the oblique support rod 4 by a fastener 7. By such a configuration, the assembly and disassembly of the bracket are more convenient. At the same time, the mold support rod 8 is connected to the oblique support rod 4 by the fastener 7, which makes it more convenient to adjust the position of the mold support rod 8 on the oblique support rod 4, so as to adjust the distance between the upper mold 6 and the lower mold 5 in the height direction, and adapt to the correction of rack pipes of different diameters.

[0025] Among them, due to the setting of the fastener 7, the loading and unloading of the upper mold 6 and the lower mold 5 are extremely convenient. Therefore, different numbers of upper molds 6 and lower molds 5 can be equipped on the mold support rod 8 according to the actual number of rack pipes that need to be corrected, so as to achieve the effect of synchronous correction of multiple rack pipes.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
