Description
Technical Field
[0001] This utility model relates to the field of screening machine technology, and in particular to a convenient high-strength screen fixing device for a square gyratory screen. Background Technology
[0002] Currently, there are various methods for fixing screens in existing technologies, commonly including bolt clamping, wedge fixing, spring hook fixing, and various quick-clamping mechanisms. However, these traditional screen fixing devices generally have some problems:
[0003] The installation and replacement of screens are often cumbersome and time-consuming, and may require operators with certain experience and tools, reducing the efficiency of equipment downtime maintenance. Many fixing devices cannot ensure that the screen is evenly tensioned throughout the screening area. Uneven screen tension can easily lead to excessive local stress, screen hole deformation, or premature fatigue damage, thereby shortening the screen's service life, reducing screening efficiency, and increasing operating costs.
[0004] Therefore, this application provides a convenient high-strength screen fixing device for square gyratory screens to meet the requirements. Utility Model Content
[0005] The purpose of this application is to provide a convenient high-strength screen fixing device for a square gyratory screen, which aims to solve the problem that the installation and replacement process of the screen is usually cumbersome, time-consuming, and may require operators to have certain experience and tools, thus reducing the downtime maintenance efficiency of the equipment.
[0006] To achieve the above objectives, this application provides the following technical solution: a convenient high-strength screen fixing device for a square gyratory screen, comprising a frame and a gyratory screen body, wherein the frame is installed on the gyratory screen body, and multiple sets of adjustment mechanisms are installed on the outer wall of the gyratory screen body, wherein symmetrical bottom beams are provided on the inner wall of the gyratory screen body, and pressing components are provided on the bottom beams, wherein the pressing components are slidably connected to the screen.
[0007] The clamping assembly also includes a movable part, a clamping part, and a horizontal plate. The movable part is a V-shaped part and is slidably connected to the top surface of the bottom beam. A set of clamping parts is hinged to the end of the movable part. The V-shaped strip of the screen is slidably connected between the movable part and the clamping parts.
[0008] A set of horizontal plates is provided above the moving part, the horizontal plates are slidably connected to the moving part, and the adjusting mechanism is connected to the moving part.
[0009] Preferably, the hinge of the clamping member is provided with a torsion spring for resetting.
[0010] Preferably, the cross-sectional shape of the clamping member is arc-shaped or rectangular.
[0011] Preferably, an auxiliary component is provided on the bottom surface of the V-shaped strip of the screen, and the bottom end of the auxiliary component is hemispherical.
[0012] Preferably, the auxiliary component is threadedly connected to the bottom surface of the V-shaped strip of the screen.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] This invention utilizes a hemispherical auxiliary component threaded to the bottom of the V-shaped strip of the screen to reduce the contact area and friction when the screen is inserted between the moving and clamping components. This makes the screen installation and removal process smoother, significantly reducing installation difficulty and time, thereby improving the efficiency of equipment downtime maintenance.
[0015] This invention introduces a clever linkage mechanism involving an adjustment mechanism, a moving component, a horizontal plate, and a clamping component. The external adjustment mechanism drives the moving component to slide on the bottom beam. Simultaneously, the cooperation between the horizontal plate and the inclined surface of the moving component reduces the included angle of the moving component, causing the clamping component to press down. Ultimately, the free end of the clamping component effectively and stably pushes the V-shaped strips of the screen inward, achieving a firm and uniform tension and fixation of the screen. This effectively avoids problems such as screen slack and localized stress concentration, ensuring screening efficiency and screen durability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Reference Figure 1-5 The illustrated square gyratory screen uses a convenient high-strength screen fixing device, which includes a frame 1, a gyratory screen body 2, an adjustment mechanism 3, and a clamping assembly. The gyratory screen body 2 is mounted on the frame 1, and a bottom beam 4 is provided inside the gyratory screen body 2. Two bottom beams 4 are arranged as a group, and multiple groups are arranged vertically. A clamping assembly is slidably connected to the top surface of the bottom beam 4. Two symmetrical clamping assemblies are connected by a set of screens 5. An adjustment mechanism 3 is provided on the outer wall of the gyratory screen body 2 to control the sliding of the clamping assembly on the bottom beam 4.
[0025] As one embodiment of this example, the clamping assembly has a V-shaped cross-section for the movable part 6, which is slidably connected to the top surface of the bottom beam 4. A set of horizontal plates 8 are provided above the movable part 6 (on the inner wall of the swing screen body 2). Through the design of the horizontal plates 8, when the movable part 6 is pulled to slide on the bottom beam 4 by the adjustment mechanism 3, the included angle of the movable part 6 can be reduced. A set of clamping parts 7 is hinged to the top free end of the movable part 6 (a torsion spring for resetting is provided at the hinge of the clamping parts 7). When the adjustment mechanism 3 is activated, the movable part 6 presses down on the clamping parts 7, thereby tightening and fixing the screen 5 placed between the movable part 6 and the clamping parts 7.
[0026] As one implementation method in this embodiment, the cross-sectional shape of the clamping member 7 is arc-shaped, which improves the smoothness of use and reduces friction.
[0027] As one embodiment of this invention, multiple sets of auxiliary parts 9 are threadedly connected to the bottom surface of the V-shaped strip of the screen 5. The ends of the auxiliary parts 9 are hemispherical, which reduces the contact area and reduces friction when the screen 5 is inserted between the moving part 6 and the pressing part 7.
[0028] The working principle of this practical device is as follows: By using the auxiliary part 9 at the bottom of the V-shaped strip of the screen 5, the friction between the bottom surface of the screen 5 and the moving part 6 is reduced when the screen 5 is inserted between the moving part 6 and the clamping part 7, thus reducing the installation difficulty; by using the adjustment mechanism 3 on the outer wall of the gyratory screen body 2, the moving part 6 slides between the bottom beam 4 and the horizontal plate 8. Through the cooperation between the horizontal plate 8 and the inclined surface of the moving part 6, the horizontal plate 8 presses down on the inclined surface of the moving part 6 during the movement, causing the inclined surface of the moving part 6 to flip downward, causing the clamping part 7 to flip at the end of the moving part 6, thereby pushing the V-shaped strip of the screen 5 inward from the free end of the clamping part 7, thus achieving fixed installation; then the excitation motor is started to make the gyratory screen body 2 vibrate on the frame 1.
[0029] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.
[0030] Components not described in detail in this article are existing technologies.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
