Description

Technical Field

[0001] This utility model relates to the field of planar shaking screen technology, specifically to a reinforced end structure of the screen frame for a planar shaking screen. Background Technology

[0002] The flat shaking screen (also known as the flat reciprocating screen) is an important screening equipment widely used in industries such as mining, metallurgy, building materials, and chemicals. It screens materials through the reciprocating motion of the screen frame. As the core component that carries the screen and materials and directly participates in the motion, the structural strength and reliability of the screen frame directly determine the working efficiency and service life of the entire equipment.

[0003] Screen frames are typically rectangular welded structures, driven by a drive unit (such as an eccentric shaft or vibratory motor) through their ends. During operation, the ends of the screen frame not only need to withstand the huge static load of the screen and materials, but also need to withstand the periodic, high-intensity alternating dynamic load and impact load from the drive unit for a long time. This complex stress condition can easily lead to fatigue damage to the end structure of the screen frame, especially the part connected to the drive component. To address this, we propose a reinforced end structure for a planar shaking screen. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reinforced end structure for a planar shaking screen, thereby solving the problem that the end of the screen frame is easily damaged due to long-term exposure to high-intensity impacts in existing technologies.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a reinforced end structure of a planar shaking screen, comprising a screen frame body, wherein the end of the screen frame body is provided with an end reinforcement structure, the end reinforcement structure is an arch bridge-shaped structure, the upper and lower sides of which are respectively connected to the upper and lower outer walls of the screen frame body, and a plurality of reinforcing ribs are provided between the middle part and the end of the screen frame body, the plurality of reinforcing ribs being arranged in a circumferential enclosing structure, the left and right sides of the circumferential enclosing structure being adapted to the side walls of the end reinforcement structure and the end of the screen frame body, and a connecting sleeve for connecting to a driving component is welded inside.

[0006] Furthermore, additional reinforcing members are provided on the upper and lower parts of the front and rear sides of the screen frame body and the end reinforcing structure, and the additional reinforcing members on the front and rear sides respectively abut against the upper and lower sides of the reinforcing rib plate enclosure structure.

[0007] The reinforced end structure of a planar shaking screen as described in claim 1, characterized in that: the outer walls of the upper and lower sides of the end reinforcement structure are provided with arc-shaped reinforcing plates, the arc-shaped reinforcing plates are arranged along the corners of the end reinforcement structure and extend to both sides.

[0008] Furthermore, support beams are fixed to the main body of the screen frame and the end reinforcement structure, and the support beams on both sides are embedded in the reinforcing ribs to form support.

[0009] Furthermore, the end reinforcement structure is a double-layer structure and is made of steel plate material.

[0010] Furthermore, the supporting beam has an I-shaped structure, and both it and the connecting sleeve are made of Q345B steel plate.

[0011] This utility model embodiment provides a reinforced end structure for a planar shaking sieve frame, which has the following beneficial effects:

[0012] 1. The end reinforcement structure adopts an arch-shaped design similar to a bridge, which can efficiently disperse concentrated stress to the main body of the screen frame, greatly improving the overall rigidity and deformation resistance of the end. Multiple reinforcing ribs form a circumferential encircling structure, forming a solid "force transmission skeleton" between the connecting sleeve and the screen frame, ensuring that the excitation force of the drive component can be transmitted smoothly and evenly, avoiding local stress concentration, and successfully solving the technical problem of easy damage to the end of the traditional planar shaking screen frame. It is particularly suitable for heavy-duty and high-intensity screening operation environments in mining, building materials, metallurgy and other fields.

[0013] 2. The additional reinforcing components and the I-beam support beams embedded in the reinforcing ribs further strengthen the connection between the screen frame body and the end reinforcing structure, effectively resisting bending and torsional stress during operation. Thicker arc-shaped reinforcing plates are set at the corners of the end reinforcing structure, specifically for strengthening vulnerable areas, greatly extending the service life of this part.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See attached document Figure 1-2 A reinforced end structure for a planar shaking screen includes a rectangular screen frame body 1, welded from shaped steel or steel plates, used to support the screen mesh (not specifically shown in the figure). An end reinforcement structure 2 is provided at the end of the screen frame body 1. This end reinforcement structure 2 has an overall arch bridge shape, with its upper and lower sides welded to the upper and lower outer walls of the screen frame body 1, respectively. Multiple reinforcing ribs 3 are provided between the middle of the end reinforcement structure 2 and the end of the screen frame body 1. These reinforcing ribs 3 are arranged in a circumferential enclosure structure, with their left and right sides respectively adapted to the side walls of the end reinforcement structure 2 and the end of the screen frame body 1 to ensure connection strength. A connecting sleeve 4 is welded inside the reinforcing ribs 3. The connecting sleeve 4 is made of Q345B steel plate, which has high strength and toughness, and can be used in high-intensity and vibration environments. The center of the connecting sleeve 4 is hollow for connecting to drive components, such as a motor output shaft or a vibration mechanism, thereby transmitting the shaking screen motion.

[0019] Among them, the end reinforcement structure 2 is an arch bridge-shaped structure, which is similar to the shape design of a bridge and can effectively disperse stress, improve overall rigidity and fatigue resistance. Preferably, the end reinforcement structure 2 is a double-layer structure, which is made of steel plate material welded on both sides. The material is high-strength steel plate, such as Q235 or Q345 series, which can further enhance the strength and stability of the end and prevent deformation under frequent vibration.

[0020] Additional reinforcing members 5 are provided on the upper and lower parts of the front and rear sides of the screen frame body 1 and the end reinforcing structure 2. The additional reinforcing members 5 are plate-shaped structures. The additional reinforcing members 5 on the front and rear sides respectively abut against the upper and lower sides of the structure enclosed by the reinforcing rib plate 3. Specifically, the additional reinforcing members 5 are fixed to the screen frame body 1 and the end reinforcing structure 2 by welding or bolting, providing additional support and enhancing the bending and torsional resistance.

[0021] The upper and lower outer walls of the end reinforcement structure 2 are provided with arc-shaped reinforcing plates 6. The arc-shaped reinforcing plates 6 are set along the corners of the end reinforcement structure 2 and extend to both sides. The arc-shaped reinforcing plates 6 are curved steel plates with a thickness greater than that of the end reinforcement structure 2. Their curvature is adapted to the contour of the end reinforcement structure 2. By welding and fixing, the bending and torsional resistance at the corners can be enhanced, stress concentration can be reduced, and service life can be extended.

[0022] Support beams 7 are fixed to the screen frame body 1 and the end reinforcing structure 2 by welding or bolting. The support beams 7 are I-shaped and made of Q345B steel plate, which has excellent bending resistance. The support beams 7 on both sides are embedded in the reinforcing ribs 3 to form support, thereby more effectively transferring the load of the connecting sleeve 4 to the end reinforcing structure 2 and the screen frame body 1.

[0023] Working principle: When the planar shaking screen is working, the drive component transmits reciprocating or vibratory motion to the screen frame body 1 through the connecting sleeve 4. The end reinforcement structure 2, the reinforcing ribs 3, the additional reinforcing parts 5, the arc-shaped reinforcing plate 6 and the support beam 7 work together to disperse the load and absorb vibration energy, preventing fatigue damage at the end of the screen frame. The arch bridge structure and the circumferentially enclosed reinforcing ribs 3 significantly improve the dynamic stiffness and strength of the end, ensuring the reliability of the screen frame in long-term operation.
