Description

Technical Field

[0001] The utility model relates to the field of correction tools, and particularly relates to a crossbeam correction device. Background Art

[0002] The cooling bed output device is a common mechanical device in the production process of steel bars, and the steel transfer output trolley of the cooling bed is the core of the cooling bed output device. During the production process of steel bars, due to the large span of the cooling bed (the length of the cooling bed is about 120m), the front and back of the steel bars are greatly affected by temperature, and the shrinkage deformation is large, resulting in problems such as chain hanging and chain breaking of the steel transfer chain often occurring when the steel transfer trolley transports the steel bars because the crossbeam of the steel transfer trolley is bent and deformed, affecting normal production. Therefore, it is necessary to frequently take the deformed crossbeam offline for correction.

[0003] The traditional method for correcting a deformed crossbeam is to first perform local flame heating on the deformed part, and then maintenance personnel take turns using a sledgehammer to strike the deformed part multiple times for correction. However, this correction method has the following problems: (1) When striking for correction, the crossbeam is not fixed, and the crossbeam is prone to deviation and injury during the process of using a sledgehammer to strike, posing a great safety hazard; (2) Manual taking turns to strike is time-consuming and laborious, and the work efficiency is low; (3) When manually using a sledgehammer for correction, the correction amount cannot be effectively controlled, often causing the other side of the deformed crossbeam to be bent and deformed, so it is necessary to rework and correct the other side again. The work intensity is high, and long-term local striking is likely to change the internal tissue structure of the steel beam, increasing the deformation amount of the crossbeam and shortening its service life. Content of the Utility Model

[0004] The utility model provides a crossbeam correction device, aiming to solve the problems of time-consuming, laborious, low work efficiency, great safety hazard when using a sledgehammer to strike the steel beam for correction at present, and the deformation amount of the crossbeam is likely to increase and its service life is shortened due to frequent striking.

Detailed implementation mode

[0019] The present utility model will be further described below in conjunction with the attached drawings:

[0020] As Figure 1-2 shown, the present utility model is a cross - beam correction device. There are two first positioning plates 9 at the bottom of the cross beam 2. There are four first connecting holes 11 on the first positioning plates 9. Two positioning blocks 10 are welded at the two sides of the cross beam 2 with dislocation. The correction device includes a support seat 5 made of square steel. Two second positioning plates 8 corresponding to the first positioning plates 9 are welded on the support seat 5. There are four second connecting holes 12 on the second positioning plates 8 corresponding to the first connecting holes 11. Specifically, the first positioning plates 9 and the second positioning plates 8 are connected by the fastening bolts 1 inserted into the first connecting holes 11 and the second connecting holes 12 and locked by nuts 7 to complete the lateral positioning of the cross beam 2. There is a third connecting hole 14 at the lower part of the positioning block 10. The positioning block 10 is fastened to the support seat 5 by the bolts inserted into the third connecting hole 14 to complete the longitudinal positioning of the cross beam 2. Two correction parts are welded at the two sides of the support seat 5 with dislocation. The correction part includes a connecting plate 13 vertically welded to the side part of the support seat 5. The free end of the connecting plate 13 is welded with a horizontally arranged T - type press base 3. And the bottom of the longitudinal part of the T - type press base 3 is welded and fixed to the top of the connecting plate 13. Reinforcing rib plates 4 are symmetrically welded between the transverse and longitudinal parts of the T - type press base 3. There is a press 6 between the reinforcing rib plates 4. The fixed end of the press 6 is fixedly connected to the transverse part of the T - type press base 3. The telescopic end of the press 6 faces the cross beam 2. The press 6 is a screw jack with a tonnage of 10t.

[0021] Before the cross beam of the steel transfer trolley needs to be corrected for bending deformation, first place the cross beam 2 with a length of 1.2 m on the support seat 5 of the correction device and make the first positioning plates 9 and the second positioning plates 8 correspond. Then insert the fastening bolts 1 into the first connecting holes 11 and the second connecting holes 12 and lock the nuts 7 to complete the lateral positioning of the cross beam 2. Then insert bolts into the third connecting holes 14 at the lower part of the positioning blocks 10 to fasten the positioning blocks 10 to the support seat 5 to complete the longitudinal positioning of the cross beam 2, so as to limit the degree of freedom of the cross beam 2 and ensure that the cross beam 2 does not shift during correction, which is safe and efficient. During correction, pressure is applied to the presses 6 of the two correction parts respectively, so that the telescopic ends of the presses 6 act on the deformed parts of the cross beam 2. At the same time, the deformed parts of the cross beam 2 are heated by gas welding. The correction work of the cross beam 2 is completed by combining the pressure applied by the presses 6 and local heating.
