Description

Technical Field

[0001] This utility model relates to the field of steel structure variable cross-section web cutting technology, specifically a guide and positioning device for steel structure variable cross-section web cutting. Background Technology

[0002] The variable cross-section web of a steel structure, also known as a web, is a steel material belonging to the central part of a steel structure. In profiles, the side where flat steel, angle steel, bulb flat steel, and sheet are welded together is considered the web. Webs are widely used in steel structure manufacturing, bridge engineering, shipbuilding, engineering machinery, and equipment manufacturing. The main function of the web is to resist shear force and also bear part of the bending moment.

[0003] However, existing steel structure variable cross-section webs need to be moved during cutting. Due to the long length of the steel structure variable cross-section web, it is easy for the web to deviate during movement, which affects the cutting accuracy of the steel structure variable cross-section web. Therefore, it does not meet the existing requirements. To address this, we propose a guiding and positioning device for cutting steel structure variable cross-section webs. Utility Model Content

[0004] The purpose of this utility model is to provide a guiding and positioning device for cutting the variable cross-section web of a steel structure, so as to solve the problems mentioned in the background art, such as the need to move the variable cross-section web of a steel structure during cutting, the fact that the variable cross-section web of a steel structure is long, and the tendency for the variable cross-section web of a steel structure to deviate during movement, thereby affecting the cutting accuracy of the variable cross-section web of the steel structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide and positioning device for cutting the web of a steel structure with variable cross-section, comprising a fixed base, a plurality of second positioning electric adjusting rods fixed on the upper surface of the fixed base, a second positioning slider fixed at both ends of the second positioning electric adjusting rods, a plurality of lifting electric telescopic rods fixed on the upper surface of the fixed base, a lifting pressure plate fixed at the top end of the lifting electric telescopic rods, a T-shaped fixed connecting plate fixed on the bottom surface of the lifting pressure plate, a plurality of first positioning electric adjusting rods fixed on the bottom surface of the T-shaped fixed connecting plate, a first positioning slider fixed at both ends of the first positioning electric adjusting rods.

[0006] Preferably, the first and second positioning electric adjustment rods are arranged in a linear array along the length of the fixed base, and the number of the first and second positioning electric adjustment rods is the same and their positions are aligned vertically.

[0007] Preferably, both the first positioning slider and the second positioning slider are L-shaped bends, and the bottom surface of the second positioning slider slides in contact with the upper surface of the fixed base.

[0008] Preferably, the first positioning slider has multiple first inlaid ball grooves on both surfaces facing the variable cross-section web of the steel structure, and the second positioning slider has multiple second inlaid ball grooves on both surfaces facing the variable cross-section web of the steel structure.

[0009] Preferably, the first and second inlaid ball grooves are arranged in a rectangular array on the surfaces of the first and second positioning sliders, respectively. A first support ball is rolled and inlaid on the inner side of the first inlaid ball groove, and a second support ball is rolled and inlaid on the inner side of the second inlaid ball groove.

[0010] Preferably, the radius and depth of the first and second inlaid ball grooves are consistent, the diameter of the first and second support balls is consistent, and the depth of the first and second inlaid ball grooves is consistent with the diameter of the first and second support balls.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a first and a second electric positioning rod to drive a first and a second positioning slider to contact the variable cross-section web of the steel structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4 As shown, a guide positioning device for cutting a variable cross-section web of a steel structure includes a fixed base 1. Multiple second positioning electric adjusting rods 7 are fixed to the upper surface of the fixed base 1. Second positioning sliders 8 are fixed to both ends of each second positioning electric adjusting rod 7. Multiple lifting electric telescopic rods 2 are also fixed to the upper surface of the fixed base 1. A lifting pressure plate 3 is fixed to the top of each lifting electric telescopic rod 2. A T-shaped fixed connecting plate 4 is fixed to the bottom surface of the lifting pressure plate 3. Multiple first positioning electric adjusting rods 5 are fixed to the bottom surface of the T-shaped fixed connecting plate 4. First positioning sliders 6 are fixed to both ends of each first positioning electric adjusting rod 5. The device positions the variable cross-section web of the steel structure from above using the first positioning electric adjusting rods 5 and the first positioning sliders 6, and positions it from below using the second positioning electric adjusting rods 7 and the second positioning sliders 8. This achieves the positioning of the variable cross-section web of the steel structure and ensures that the variable cross-section web of the steel structure does not shift during movement.

[0020] The first positioning electric adjusting rod 5 and the second positioning electric adjusting rod 7 are both arranged in a linear array along the length of the fixed base 1. The number of the first positioning electric adjusting rod 5 and the second positioning electric adjusting rod 7 are the same and their positions are aligned vertically. The first positioning slider 6 and the second positioning slider 8 are both L-shaped bends, and the bottom surface of the second positioning slider 8 slides in contact with the upper surface of the fixed base 1. The L-shaped first positioning slider 6 and the second positioning slider 8 contact the upper surface, bottom surface and inner wall of the variable cross-section web of the steel structure, respectively, so that the first positioning slider 6 and the second positioning slider 8 position the variable cross-section web of the steel structure from the inside.

[0021] The first positioning slider 6 has multiple first inlaid ball grooves 11 on both surfaces facing the variable cross-section web of the steel structure, and the second positioning slider 8 has multiple second inlaid ball grooves 12 on both surfaces facing the variable cross-section web of the steel structure.

[0022] The radius and depth of the first inlaid ball groove 11 and the second inlaid ball groove 12 are consistent. The diameter of the first support ball 9 and the second support ball 10 is consistent. The depth of the first inlaid ball groove 11 and the second inlaid ball groove 12 is consistent with the diameter of the first support ball 9 and the second support ball 10. The first inlaid ball groove 11 and the second inlaid ball groove 12 are distributed in a rectangular array on the surface of the first positioning slider 6 and the second positioning slider 8. The first support ball 9 is rolled and inlaid on the inner side of the first inlaid ball groove 11, and the second support ball 10 is rolled and inlaid on the inner side of the second inlaid ball groove 12. The first support ball 9 and the second support ball 10 are used to reduce the frictional resistance between the steel structure variable cross-section web and the first positioning slider 6 and the second positioning slider 8, so that after the steel structure variable cross-section web is positioned by the first positioning slider 6 and the second positioning slider 8, the steel structure variable cross-section web can move along the length direction of the fixed seat 1.

[0023] Working principle: First, the power supply to the device is turned on. After the power is turned on, the lifting electric telescopic rod 2 is energized and starts, driving the lifting pressure plate 3, T-shaped fixed connecting plate 4, and first positioning electric adjusting rod 5 to move upward. This makes the distance between the first positioning electric adjusting rod 5 and the second positioning electric adjusting rod 7 greater than the thickness of the steel structure variable cross-section web. Then, the steel structure variable cross-section web to be cut is placed on the surface of the second positioning slider 8. Subsequently, the second positioning electric adjusting rod 7 starts and pushes the second positioning slider 8 to slide on the surface of the fixed seat 1 until the second support ball 10 rolled on the surface of the second positioning slider 8 fits against the inner wall of the steel structure variable cross-section web. The second positioning electric adjusting rod 7 makes all the second positioning sliders 8 contact the steel structure variable cross-section web. At this time, the second positioning sliders 8 position the steel structure variable cross-section web from below. Then, the lifting electric telescopic rod 2... The lifting pressure plate 3 is lowered, causing the first support ball 9 embedded in the first positioning slider 6 to contact the top of the steel structure variable cross-section web. At this time, the lifting electric telescopic rod 2 stops moving, and the first positioning electric adjusting rod 5 is energized. After being energized, the first positioning electric adjusting rod 5 pushes the first positioning slider 6 closer to the inner wall of the steel structure variable cross-section web until the first support ball 9 contacts the inner wall of the steel structure variable cross-section web, thus achieving upper and lower positioning of the steel structure variable cross-section web. At the same time, the first positioning slider 6 applies a downward force to the steel structure variable cross-section web, preventing the steel structure variable cross-section web from swaying up and down. Finally, the steel structure variable cross-section web is pushed, moving the part of the steel structure variable cross-section web to be cut to below the cutting component for cutting. This quickly achieves the positioning of the steel structure variable cross-section web and ensures that the steel structure variable cross-section web will not deviate or sway during cutting, thus ensuring the cutting accuracy of the steel structure variable cross-section web.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
