Description

Technical Field

[0001] The present invention relates to the field of screen installation accessories, and particularly to a tensioning type fixing bent iron for screen installation. Background Art

[0002] The tensioning type installation method is widely used in the installation of screens such as rubber, polyurethane, metal bar screens, metal woven screens, and polyurethane bar welded screens. The traditional screen installation method is to set tensioning hooks at the edges of the screen, and then use a "C" - shaped fixing bent iron and carriage bolts to fix them on the screen machine wall panel; the fixing bent iron includes three parts: an upper support plate, a vertical plate, and a lower hook plate. The specific fixing method is to hook the lower hook plate on the screen tensioning hook, the upper support plate is supported on the screen machine wall panel, bolt holes are uniformly arranged on the vertical plate, and the carriage bolts pass through the bolt holes on the vertical plate and穿出 the holes on the wall panel. By tightening the carriage bolts at both ends of the screen, the entire screen surface is in a tensioned state, achieving the purpose of fixing the screen, and at the same time being beneficial to the screening of materials and improving the service life of the screen. However, this screen installation method has a drawback during installation: since different stiffeners will be set on the screen machine wall panel for reinforcement, the bolt holes on the tensioning plate cannot be accurately positioned and standardized during design, and the bolt holes of each fixing bent iron are not necessarily the same. This brings trouble to the installation. First, it requires designers to avoid the stiffeners on the screen machine wall panel during design and accurately position each installation hole. Second, on - site, oxygen cutting is often used to re - cut holes on the wall panel or the fixing bent iron, which may affect the strength of the screen machine, increase the workload and difficulty of installation, and waste a lot of manpower and material resources. Summary of the Invention

[0003] The present invention aims to solve the deficiencies of the prior art and provides a fixing bent iron for tensioning type screen installation, which has low installation difficulty and is convenient to use.

The upper support plate and the lower hook plate are both bent to one side, and a C - shaped groove is arranged on the inner side of the vertical plate.

[0005] Furthermore, the width of the lower hook plate of the fixing bent iron is 40 - 100 mm shorter than the width of the upper support plate.

[0006] A mounting device for a tensioning screen comprises a screen body, a screen support frame, a screen and a fixed bent iron, wherein the screen support frame is welded to a beam of a screening machine, the screen is laid flat on the screen support frame, and upwardly bent tensioning hooks are arranged at both ends of the screen, and the characteristic is that: the fixed bent iron is in a "giant" shape, comprising an upper support plate, a vertical plate, a lower hook plate and a C-shaped groove, the upper support plate and the lower hook plate are both bent to one side, and a C-shaped groove is arranged on the inner side of the vertical plate; the bent tensioning hooks are hooked on the lower hook plates of the fixed bent iron on both sides, and the fixed bent iron is fixed to the wall plate of the screen body with T-bolts, and the tail of the T-bolts is in the C-shaped groove.

[0007] Furthermore, a rubber or polyurethane protective sleeve in contact with the bottom surface of the screen is provided on the top of the screen support frame.

[0008] Compared with the prior art, the advantages of the present invention are as follows: the present invention, through the setting of the C-shaped groove, changes the original fixed bolt hole into a bolt position that can be conveniently adjusted according to the opening conditions of the screen machine wall panel, which simplifies the designer's surveying and mapping, and is conducive to the standardization of fixed bent iron processing; reduces the work intensity of the installation workers, does not need to use oxygen cutting, saves time and maintenance costs; at the same time, the C-shaped groove also plays a role in strengthening the fixed bent iron.

[0013] The present invention is further described below in conjunction with the accompanying drawings.

[0014] like Figure 1 , Figure 2 As shown, the fixed bent iron 4 is in a "giant" shape, including an upper support plate 41, a vertical plate 42, a lower hook plate 43 and a C-shaped groove 44. The upper support plate 41, the vertical plate 42, and the lower hook plate 43 are sequentially connected into a whole, the upper support plate 41 and the lower hook plate 43 are both bent to one side, and a C-shaped groove 44 is provided on the inner side of the vertical plate 42.

[0015] like Figure 3As shown, the screen support frame 2 is installed on the beam of the screen machine, the screen 3 is laid flat on the screen support frame 2, and the two ends of the screen 3 are provided with upward bending tension hooks 31. The bending tension hooks 31 are folded on the angle iron 7, and the angle iron 7 is arranged on the inner wall plate of the screen body 1.

[0016] When the present invention is installed, it is fixedly connected to the inner wall plate of the screen body 1 by the T-bolt 5, the lower hook plate 43 hooks the bent tension hook 31, and the T-bolt 5 is installed in the C-shaped groove 44, that is, the tail of the T-bolt 5 is in the C-shaped groove 44. The T-bolt 5 can slide in the C-shaped groove 44 to adjust the installation position to meet the installation hole requirements at different positions on the screen machine.

[0017] like Figure 3 As shown, a protective cover 6 in contact with the bottom surface of the screen 3 is provided on the top of the screen support frame 2 to support and protect the screen.

[0018] The protective cover 6 is buckled on the screen support frame 2 and is made of rubber or polyurethane material.

[0019] like Figure 1 , Figure 2 As shown, the width of the lower hook plate 43 of the fixed bent iron 4 is 40-100mm shorter than that of the upper support plate 41, so that the lower hook plate 43 can hook the bent tensioning hooks 31 at both ends of the screen 3. After the upper support plate 41 supports the side wall of the screen body 1, there is a certain tensioning gap between the screen 3 and the side plate of the screen body 1. By tightening the T-bolt 5, the screen 3 can be tightened and fixed.

[0020] The present invention changes the original fixed bolt holes into bolt positions that can be conveniently adjusted according to the opening conditions of the screen wall panel through the provision of C-shaped grooves, thereby simplifying the designer's surveying and mapping, and being conducive to the standardization of fixed bent iron processing; reducing the work intensity of the installation workers, eliminating the need for oxygen cutting, saving time and maintenance costs; and at the same time, the C-shaped groove also plays a role in strengthening the fixed bent iron, reducing deformation damage under vibration due to strength reasons.
