Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

1-4, the screen repairing tool comprises an operation table 2, wherein a plurality of positioning pieces 1 for radially pulling the screen, a plurality of pressing pieces 3 for axially pressing the screen and at least one lifting device 4 for lifting the screen are arranged on the operation table 2.

The operation table 2 can provide support for the integral repair tool; the positioning piece 1 can pull the screen mesh in the radial direction from a plurality of positions, wherein the same pulling force can be set by the positioning piece, so that the common stress in a plurality of directions is realized; the compressing pieces 3 can position the screen after moving from bottom to top, specifically, one compressing piece 3 can be detachably arranged on the operating platform 2, so that the screen can be arranged among the compressing pieces 3; the lifting mechanism can realize that the screen mesh moves from bottom to top, and the screen mesh is fixed through the pressing piece 3 and lifting fit. In addition, since the lifting device 4 can lift the whole screen, the whole screen can be directly moved to the plurality of compacting pieces 3, and the whole screen is fixed. It is known that the arrangement height of the plurality of pressing members 3 should be the same. Preferably, the compressing element 3 is provided with at least three, which can center the screen, and further position the whole plane. Furthermore, the lifting device 4 is an automatic lifting device 4, so that the fixation of a plurality of positions can be automatically and synchronously realized; the pressing piece 3 is provided with a positioning part 31 matched with the frame of the screen. Because the rigidity of frame is higher than the screen cloth, through the frame of locating part 31 block the screen cloth, can not pull the screen cloth and warp, conveniently repair.

As another specific embodiment, the positioning member 1 is a pull claw assembled on the console by an elastic band. The screen mesh structure is convenient and quick to operate through the elastic belt, can adapt to the position of the screen mesh more relative to the track type structure, and after the pull claws at a plurality of positions are installed, the elastic belts can automatically balance stress, so that the screen mesh stress is balanced.

As a further specific embodiment, the pressing element 3 is a hook which is arranged in a turned-over manner and is bent inwards in the radial direction of the screen. Because the frame of screen cloth is the turn-up form, the crotch that sets up through the upset can be fine with turn-up cooperation to, based on the shape of crotch, the technical effect of restriction screen cloth plane removal and upward movement that can be better is realized. In addition, through the radial inwards crooked setting of crotch along the screen cloth, can carry out the radial tensile with the screen cloth for the atress effect of screen cloth is better.

As another specific embodiment, the lifting device 4 is a lifting cylinder. The cylinder has compact structure, light weight, small occupied space and high reliability, and is convenient to adjust. Further, the air cylinder is fixedly arranged on the operation table 2, and an output rod of the air cylinder upwards penetrates through the operation table 2 to lift. Of course, this embodiment is merely a preferred example, and in a specific embodiment, the lifting device 4 may be an electric cylinder, a hydraulic cylinder, a linear guide, or the like.

As another specific embodiment, the lifting device 4 is disposed below the pressing member 3. The screen cloth can be closely stressed when being fixed, the bending moment is reduced, and the bending deformation of the fixed screen cloth is further prevented. Specifically, the jacking cylinder and the hooks comprise four.

As another specific embodiment, the operation table 2 is provided with a rotating device 5 for rotating the screen. Can rotate the screen cloth when a plurality of positions need to be repaired, convenient operation.

As another specific embodiment, the rotating device 5 is a rotating wheel disposed in the middle of the console 2 and contacting with the bottom surface of the screen, and the rotating wheel is disposed along the circumferential direction of the screen. Through the runner, can reduce the sliding friction of screen cloth to the runner sets up along the circumference of screen cloth and can guarantee that the direction of rotation of screen cloth is along circumference, can also fix a position the frame inboard of screen cloth. In addition, the height of runner is less than the height of the output rod of jacking cylinder when the screen cloth is in fixed state, prevents to appear the motion interference. It can also be realized that the screen cloth is rotated by the rotating wheel in the non-fixed state.

As another specific embodiment, the operation table 2 is further provided with at least three limiting parts 6 contacting with the side edges of the screen. By providing the stopper 6 in contact with the side edge of the screen, the screen can be restricted from being displaced during rotation. Through at least three spacing portion 6, can be to the screen cloth centering, in specific implementation, spacing portion 6 can be four, can prevent that one of them spacing portion 6 from appearing the position deviation and leading to the screen cloth to appear the position deviation.

As another specific embodiment, the limiting part 6 is rotatably disposed on the console 2. Sliding friction between the limiting part 6 and the screen mesh can be reduced through the arrangement of rotation.

As another specific embodiment, the limiting part 6 includes a fixed cylinder 61 and a rotary cylinder 62, the fixed cylinder 61 is fixedly disposed on the console 2, and the rotary cylinder 62 is connected to the fixed cylinder 61 through a bearing 63. The sliding friction in the limiting part 6 can be converted into rolling friction, and the service life of the limiting part 6 is prolonged.

The screen repair tool provided by the embodiment has the following use process:

1. one of the hooks is detached, the screen is placed on the rotating wheel, the plane position is positioned through the rotating wheel and the limiting part 6, and after the screen is rotated to the position needing to be repaired, the hooks are installed;

2. the pull claws are arranged along the circumferential direction, so that the screen mesh is pulled from a plurality of positions, and the stress balance is realized;

3. the plurality of jacking cylinders synchronously move upwards and press the screen with the hooks.
