Description

Technical Field

[0001] The present invention relates to the field of development of mechanical motion, and specifically to a multi-suspension plate translation mechanism. Background Art

[0002] The grate cooler is a cooling device in the clinker burning system of a cement plant. Its main function is to cool and convey cement clinker. During the conveying process, a material supporting platform is required to move back and forth. The higher the linearity accuracy of the movement of the material supporting platform of the grate cooler, the narrower the cooling air outlet on the platform, the greater the wind pressure, the better the cooling effect, which is beneficial to improving the working efficiency and cooling quality of the whole machine.

[0003] At present, the transmission device of the material supporting platform of the grate cooler widely uses a mechanical structure containing kinematic pairs. During the long-term movement process, due to friction, the moving pair guide rail will be worn, resulting in a reduction in movement accuracy. In severe cases, it may even be unable to slide, while the rotating pair will be worn, resulting in an increase in movement clearance, a reduction in movement accuracy, and deformation of local parts, thereby affecting the movement accuracy of the material supporting platform.

[0004] In order to overcome the problems brought by kinematic pairs, some devices also use hydraulic transmission. However, since the hydraulic oil will inevitably have leakage, compressibility, and the hydraulic pipeline will produce elastic deformation, it will also affect the movement accuracy of the platform. Workers have to perform regular maintenance and debugging. However, the transmission device of the grate cooler is in a relatively enclosed space, and people cannot approach during equipment operation, nor can they replace structural parts, and it is even more difficult to perform high-frequency maintenance and debugging. Only during the shutdown and maintenance period can the equipment be adjusted and replaced.

[0005] To solve the above technical problems, it is necessary to develop a transmission device with high translation accuracy, large load-bearing capacity, good movement reliability, and no need for high-frequency maintenance and debugging for the material supporting platform of the grate cooler. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a multi-suspension plate translation mechanism, which has high translation accuracy, large load-bearing capacity, good movement reliability, does not require frequent maintenance and debugging, and is suitable for use in the material supporting platform of the grate cooler.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is: The present invention includes a moving platform, a flexible connection unit, and a swing rod. The swing rods are symmetrically arranged at both ends of the moving platform. The flexible connection units are symmetrically arranged on both sides of the swing rods. The flexible connection unit includes a suspension plate and a connecting plate. One end of the suspension plate is fixed to the frame, the other end of the suspension plate is fixed to the swing rod, and the other end of the swing rod is fixed to the moving platform through the connecting plate.

[0008] A further improvement of the present invention lies in that: the suspension plates include a first suspension plate and a second suspension plate symmetrically arranged on both sides of the swing rod, the connecting plates include a first connecting plate and a second connecting plate symmetrically arranged on both sides of the swing rod, one end of the first suspension plate and the second suspension plate is fixedly connected to the frame, and the other ends of the first suspension plate and the second suspension plate are both fixedly connected to the swing rod; the other end of the swing rod is fixedly connected to the first connecting plate and the second connecting plate respectively, and the other ends of the first connecting plate and the second connecting plate are both fixedly connected to the moving platform.

[0009] A further improvement of the present invention lies in that: the moving platform and the swing rod are both made of rigid materials, and the suspension plates and the connecting plates are both made of flexible steel plates.

[0010] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present invention are as follows: The present invention has a simple structure and a unique design, and realizes the translational effect of the moving platform without any kinematic pairs. Since the transmission is not realized by kinematic pairs, there is no friction and wear phenomenon, so there is no need for workers to perform high-frequency maintenance and debugging, and it truly achieves green environmental protection and no pollution, improving the service life of the entire mechanism.

[0011] The translational effect of the moving platform is highly accurate. The narrower the cooling air outlet on the moving platform, the greater the air pressure and the better the cooling effect, which is beneficial to improving the working efficiency and cooling quality of the whole machine. At the same time, the device adopts a multi-flexible suspension plate structure, and the force and motion are transmitted through the deformation of the flexible plate, greatly improving the bearing capacity of the entire transmission mechanism, and no maintenance and debugging are required during the working process. Therefore, the present invention is more suitable for the transmission device of the grate cooler. While solving the transmission problem of the grate cooler, it improves the bearing capacity and optimizes the motion characteristics of the moving platform, and it is necessary to promote it.

[0014] The following further describes the present invention in detail with reference to the embodiments: A multi-suspension plate translation mechanism, as Figures 1 - 3As shown in the figure, it includes a moving platform 6, a flexible connection unit, and a swing rod 4. Both the moving platform 6 and the swing rod 4 are made of rigid materials and are not prone to elastic deformation when subjected to external forces, and still maintain their original shape and size. The flexible connection unit is made of flexible steel plates, such as stainless steel plates, high-strength low-alloy steel plates, etc., all of which are flexible plates and have a certain ability of elastic deformation. They will produce a certain amount of elastic deformation under the action of external forces and can return to the initial state when the external force is removed.

[0015] As Figure 1 As shown in the figure, the swing rods 4 are symmetrically arranged at both ends of the moving platform 6, and the flexible connection units are symmetrically arranged on both sides of the swing rods 4. The flexible connection unit includes a suspension plate and a connecting plate. The suspension plate is arranged between the frame 1 and the swing rod 4, and the connecting plate is arranged between the swing rod 4 and the moving platform 6.

[0016] One end of the suspension plate is fixed to the frame 1, and the other end of the suspension plate is fixed to the swing rod 4. The other end of the swing rod 4 is fixed to the moving platform 6 through the connecting plate. As Figure 2 As shown in the figure, when the external force acts to the right on the suspension plates fixed to the swing rods 4 at both ends of the moving platform 6, the suspension plates on both sides of the swing rod 4 are deformed and bent to the right at the same time, driving the rigid swing pieces 4 fixedly connected thereto to move to the right. The reaction force of the rightward translation of the swing rod 4 acts on the connecting plate connected thereto. Under the action of this reaction force, the connecting plate is deformed and bent to the left while driving the rigid moving platform 6 connected thereto to move to the left. Similarly, the flexible connection units symmetrically arranged at both ends of the moving platform 6 drive the moving platform 6 to move left synchronously at the same time. That is, when the suspension plates on both sides of the swing pieces 4 are simultaneously subjected to an external force acting to the right, the connecting plates on both sides drive the moving platform 6 connected thereto to move to the left. The structures at both ends of the moving platform 6 are symmetric, so the simultaneous leftward translation of both ends of the moving platform 6 shows the effect of the leftward translation of the moving platform 6. Repeating this cycle, the moving platform 6 achieves a high-precision translation effect within the effective working space.

[0017] Similarly, as Figure 3 As shown in the figure, when the external force acts to the left on the suspension plates on both sides of the swing pieces 4, the connecting plates on both sides drive the moving platform 6 connected thereto to move to the right. Since the structures at both ends of the moving platform 6 are symmetrically arranged, the simultaneous rightward translation of both ends of the moving platform 6 shows the effect of the rightward translation of the moving platform 6. Repeating this cycle, the moving platform 6 achieves a high-precision translation effect within the effective working space.

[0018] As Figure 1As shown in the figure, the suspension plates include a first suspension plate 2 and a second suspension plate 7 symmetrically arranged on both sides of the swing rod 4. The connecting plates include a first connecting plate 3 and a second connecting plate 5 symmetrically arranged on both sides of the swing rod 4. One end of the first suspension plate 2 and the second suspension plate 7 is fixedly connected to the frame 1, and the other ends of the first suspension plate 2 and the second suspension plate 7 are both fixedly connected to the swing rod 4. The other end of the swing rod 4 is respectively fixedly connected to the first connecting plate 3 and the second connecting plate 5, and the other ends of the first connecting plate 3 and the second connecting plate 5 are both fixedly connected to the moving platform 6.

[0019] As Figure 2 shown in the figure, when the first suspension plate 2 and the second suspension plate 7 fixed to the frame 1 are simultaneously deformed under the action of an external force to the right, the first suspension plate 2 and the second suspension plate 7 bend to the right at the same time, driving the rigid member swing rod 4 fixedly connected thereto to translate to the right. At the same time, the reaction force of the swing rod 4 translating to the right acts on the first connecting plate 3 and the second connecting plate 5. While the first connecting plate 3 and the second connecting plate 5 elastically deform and bend to the left, they drive the moving platform 6 fixedly connected to the first connecting plate 3 and the second connecting plate 5 to translate to the left. Since the structures at both ends of the moving platform 6 are symmetrical, when the first suspension plate 3 and the second suspension plate 5 at both ends are simultaneously subjected to an external force to the right, both ends of the moving platform 6 will translate to the left at the same time, and thus the moving platform 6 achieves a high-precision translation effect in the plane.

[0020] Similarly, as Figure 3 shown in the figure, when the first suspension plate 2 and the second suspension plate 7 fixed to the frame 1 are simultaneously deformed under the action of an external force to the left, the first suspension plate 2 and the second suspension plate 7 bend to the left at the same time, driving the swing rod 4 fixedly connected thereto to translate to the left. At the same time, the reaction force of the swing rod 4 translating to the left drives the first connecting plate 3 and the second connecting plate 5 to bend to the right simultaneously, and drives the moving platform 6 connected thereto to translate to the right. The swing rods 4 and the flexible connection units at both ends of the moving platform 6 are symmetrically arranged. Therefore, when both ends of the moving platform 6 are subjected to an external force to the left, both ends of the moving platform 6 will translate to the right at the same time, and finally the moving platform 6 achieves a high-precision translation effect in the plane.

[0021] In short, all of the above transmissions achieve the translation effect of the moving platform 6 without any kinematic pairs. It does not contain kinematic pairs, and all transmissions are achieved by the elastic deformation of the suspension plates and the connecting plates, rather than by kinematic pairs. Therefore, there is no friction or wear phenomenon, and there is no need for workers to perform high-frequency maintenance and debugging. It truly achieves green environmental protection and no pollution. Therefore, the translation effect of the moving platform 6 under the action of the flexible connection unit is more suitable for use in the material supporting platform of the heavy-duty grate cooler and is necessary to be promoted. Finally, it should be noted that the above embodiments are only examples for clearly illustrating the present invention and are by no means limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here, and the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
