DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the protection scope of the utility model.

[0020] Please refer to the attached Figures 1-5The embodiment is a straightening device for steel structure column and beam: including handle 1, the handle 1 is fixedly connected with the protective plate 2, the protective plate 2 is slidably connected with two opposite sliding rollers 3, two the rollers 3 are located on the same horizontal line, the middle part of two the rollers 3 is provided with a correction pressing block 4, the correction pressing block 4 is located above the roller 3, the correction pressing block 4 is fixedly connected with a push rod 5, the push rod 5 is slidably connected with the handle 1, and the moving direction of the push rod 5 is perpendicular to the horizontal direction of the two rollers 3.

[0021] The protective plate 2 is a prism structure as a whole, the transverse width of the protective plate 2 is smaller at the position of the handle 1, and the transverse width is larger at the lower position, when the column and beam straightening work is carried out, the column and beam are located between the two rollers 3 and the correction pressing block, the correction pressing block 4 is aimed at the bending midpoint of the column and beam, then under the action of the push rod 5, the correction pressing block presses the bending point of the column and beam to move, so as to correct the bending of the column and beam, when in use, the user holds the handle 1 with hands, the protective plate 2 is located close to the human body on one side, the protective plate 2 protects the human body on this side, and the extrusion direction of the push rod 5 to the correction pressing block is perpendicular to the horizontal direction of the two rollers 3.

[0022] Further, in the actual construction environment, the bending angles of each column and beam are different, in order to make the device better adapt to different straightening conditions, the two rollers 3 are rotatably connected to connecting rods 7, the upper ends of the two connecting rods 7 are hingedly connected to an adjusting sleeve 6, as shown in Figure 1 and Figure 2 When the adjusting sleeve 6 moves downward, the adjusting sleeve 6 drives the lower ends of the connecting rods 7 to move downward, the two rollers 3 are relatively far away from each other, at this time, the column and beam with larger bending curvature can be better adapted, on the contrary, when the bending curvature is smaller, the adjusting sleeve 6 is moved upward, so that the two rollers 3 are close to each other, so that the column and beam can be accurately corrected, as shown in Figure 3 The lower part of the connecting rod 7 is provided with a through slot 8, the roller 3 is installed in the through slot 8, and the width of the through slot 8 is greater than the width of the column and beam, when the straightening work is carried out, the column and beam passes through the through slot 8 above the roller 3, and the left and right sides of the through slot 8 limit the column and beam, so that the column and beam is prevented from being separated during the straightening process.

[0023] As shown in Figure 4 The horizontal movement of the roller 3 is limited by the sliding block 9, the two sliding grooves 10 on the protective plate 2 are on the same horizontal line, the sliding block 9 slides horizontally in the sliding groove 10 under the action line of the guide rod 11, the roller 3 is rotatably connected to the sliding block 9 through a connecting pin, and the accuracy of the column and beam after straightening is ensured under the guidance of the sliding block 9, so that the two rollers 3 are on the same horizontal line.

[0024] The adjusting sleeve 6 is sleeved on the handle 1, and the recess 14 is formed on the protective plate 2 to avoid the interference between the adjusting sleeve 6 and the protective plate 2. The adjusting sleeve 6 and the handle 1 are fixed by the fixing bolt 13, the fixing bolt 13 is pressed through the bolt hole to the handle 1 to improve the friction between the handle 1 and the fixing bolt 13, and the stability of the position of the handle 1 and the adjusting sleeve 6 is ensured. In addition, the limiting hole can be additionally arranged on the handle 1, and the fixing bolt 13 is embedded into the limiting hole after passing through the bolt hole, so that the fixing firmness of the adjusting sleeve 6 is improved.

[0025] The baffle 15 is connected between the handle 1 and the protective plate 2, the upper end of the baffle 15 is made of rubber, and the baffle 15 protects the hands of the user, and separates the hand holding part of the handle 1 from the straightening part of the device.

[0026] The push rod 5 is a hydraulic rod, and the reciprocating movement of the push rod 5 is driven by an external hydraulic pump, so that the manpower is saved, and the extension amount of the push rod 5 can be accurately controlled. The lower end of the correcting pressing block 4 is a semi-cylindrical structure, and the clamping groove 16 is formed in the middle part of the correcting pressing block 4. The column beam is located in the clamping groove 16 during the straightening work, and the clamping groove 16 limits the column beam to avoid the disengagement of the correcting pressing block 4 and the column beam.

[0027] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
