Description

Technical Field

[0001] The present invention relates to the research and development field of mechanical motion, and specifically to a translational transmission mechanism. Background Art

[0002] A 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, and a reciprocating motion of a material supporting platform is required during the conveying process. At the same time, the transmission mechanism of the grate cooler is in a high-temperature and relatively enclosed space. During the operation of the equipment, the staff cannot approach, cannot replace structural parts, and it is not easy to perform high-frequency maintenance and debugging. High reliability of the transmission mechanism is required to smoothly achieve the cooling and conveying of cement clinker.

[0003] Currently, the transmission mechanism of the material supporting platform of the grate cooler widely adopts a mechanical structure containing kinematic pairs. During long-term motion, due to friction, the sliding pair guide rail will be worn, resulting in a reduction in motion accuracy. In severe cases, it may even be unable to slide, and the cooling and conveying of cement clinker cannot be completed. The rotating pair will also be worn, resulting in an increase in motion clearance, a reduction in motion accuracy, and deformation of local parts, thereby affecting the motion accuracy of the final end material supporting platform.

[0004] To overcome the problems brought by the above kinematic pairs, some mechanisms adopt hydraulic transmission. However, since hydraulic oil will inevitably have leakage, compressibility, and the hydraulic pipeline will produce elastic deformation, it will also affect the motion accuracy of the material supporting platform. To ensure the motion accuracy of the motion platform using hydraulic transmission, workers have to perform regular maintenance and debugging, which conflicts with the working environment of the grate cooler.

[0005] To solve the above technical problems, it is necessary to develop a transmission mechanism with high translational accuracy, good motion 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 translational transmission mechanism, which realizes a high-precision translational effect of the motion platform through the deformation of a flexible member. It does not contain kinematic pairs, does not require high-frequency maintenance and debugging, and is suitable for use in the high-temperature and enclosed transmission mechanism 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 motion platform, a swing rod arranged in parallel above the motion platform, and a flexible connection unit fixedly connected to the swing rod. The swing rods are symmetrically arranged at both ends of the motion platform. The flexible connection unit includes a suspension plate and a connecting plate. One end of the suspension plate is fixedly connected to the center of the swing rod, and the other end is fixedly connected to the frame above the swing rod. The swing rod is fixedly connected to the motion platform through the connecting plate.

[0008] A further improvement of the present invention lies in that one end of the connecting plate is fixed to the swing rod, and the other end is fixed to the moving platform.

[0009] A further improvement of the present invention lies in that the connecting plate includes a first connecting plate and a second connecting plate, and the first connecting plate and the second connecting plate are arranged in an interleaved and symmetrical manner between the moving platform and the swing rod.

[0010] A further improvement of the present invention lies in that both the moving platform and the swing rod are made of rigid materials, and both the suspension plate and the connecting plate are made of flexible steel plates.

[0011] Due to the adoption of the above technical solutions, the beneficial effects achieved by the present invention are as follows: The structure of the present invention is simple and novel. The movement and force transmission of the transmission mechanism are realized by the deformation of flexible components, and there are no kinematic pairs in the process of movement and force transmission, so there is no friction and wear phenomenon. More importantly, it does not require high-frequency maintenance and debugging by workers, truly achieving green environmental protection and no pollution, and improving the service life of the entire mechanism. It is suitable for the small-range reciprocating movement of the grate cooler's material supporting platform, fundamentally solving the problems faced by the current grate cooler transmission mechanism.

[0012] Therefore, the present invention is more suitable for the transmission mechanism of the grate cooler. While solving the transmission problem of the grate cooler, it improves the service life of the whole machine equipment, optimizes the movement characteristics of the moving platform, and it is necessary to promote and apply it.

[0015] The following further describes the present invention in detail with reference to the embodiments: A translational transmission mechanism, such as Figures 1-6 shown, which includes a moving platform 6, a swing rod 3 arranged in parallel above the moving platform 6, and a flexible connection unit fixedly connected to the swing rod 3. The swing rod 3 is symmetrically arranged at both ends of the moving platform 6. Under the action of an external force, the flexible connection unit undergoes a certain elastic deformation, and this elastic deformation drives the moving platform 6 through the swing rod 3 to achieve a horizontal and high-precision translational effect.

[0016] Both the moving platform 6 and the swing rod 3 are made of rigid materials and are not prone to elastic deformation under the action of an external force, and still maintain their original shapes and dimensions. The flexible connection units are all made of flexible steel plates, such as stainless steel plates, high-strength low-alloy steel plates, etc., and are all flexible plates with a certain elastic deformation ability. They produce a certain elastic deformation under the action of an external force and can return to the initial state when the external force is removed.

[0017] The flexible connection unit includes a suspension plate 2 and a connection plate. One end of the suspension plate 2 is fixedly connected to the center of the swing rod 3, and the other end of the suspension plate 2 is fixedly connected to the frame 1 above the swing rod 3. The swing rod 3 is fixedly connected to the moving platform 6 through the connection plate. As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the external force acts on the suspension plates 2 on both sides simultaneously. The suspension plates 2 on both sides deform in the direction of the force at the same time. The deformation of the suspension plate 2 drives the swing rod 3 fixed to its bottom to move parallel in the direction of the force. While the swing rod 3 is moving, the reaction force acts on the connection plate below the swing rod 3, and the connection plate is forced to deform in the direction opposite to the reaction force. While the connection plates on both sides are deforming, they drive the moving platform 6 fixed to their lower part to move parallel in the direction of the reaction force.

[0018] As Figures 1-6 shown, one end of the connection plate is fixedly connected to the swing rod 3, and the other end is fixedly connected to the moving platform 6. The connection plate includes a first connection plate 4 and a second connection plate 5. The first connection plate 4 and the second connection plate 5 are arranged alternately and symmetrically between the moving platform 6 and the swing rod 3. As Figure 2 and Figure 5As shown in the figure, when the suspension plates 2 on both sides of the moving platform 6 are simultaneously subjected to external forces to the right, the suspension plates 2 on both sides deform to the right simultaneously and drive the swing rods 3 fixedly connected to their bottoms to translate to the right. The reaction forces of the two swing rods 3 translating to the right act on the first connecting plate 4 and the second connecting plate 5 fixedly connected to their ends. The first connecting plate 4 and the second connecting plate 5 deform simultaneously in the direction of the reaction force, that is, elastically deform to the left. While the first connecting plate 4 and the second connecting plate 5 elastically deform to the left, they drive the two endpoints of the moving platform 6 to translate to the left simultaneously, thereby achieving the moving effect of the moving platform 6 translating to the left. Repeating this cycle, the moving platform 6 can achieve a high-precision translation effect within the effective working space.

[0019] As Figure 3 and Figure 6 shown in the figure, when the suspension plates 2 on both sides of the moving platform 6 are simultaneously subjected to external forces to the left, the suspension plates 2 on both sides deform to the left simultaneously and drive the swing rods 3 fixedly connected to their bottoms to translate to the left. While the two swing rods 3 translate to the left, the reaction forces act on the first connecting plate 4 and the second connecting plate 5 fixedly connected to their ends. The first connecting plate 4 and the second connecting plate 5 deform simultaneously in the direction of the reaction force, that is, elastically deform to the right. While the first connecting plate 4 and the second connecting plate 5 elastically deform to the right, they drive the two endpoints of the moving platform 6 fixedly connected to them to translate to the right simultaneously, thereby achieving the moving effect of the moving platform 6 translating to the right. Repeating this cycle, the moving platform 6 achieves a high-precision translation effect in the plane within the effective working space.

[0020] As Figures 1-6 shown in the figure, the first connecting plate 4 and the second connecting plate 5 are symmetrically and staggeredly arranged between the swing rod 3 and the moving platform 6, which can effectively increase the stability of the moving platform 6 and is conducive to optimizing the motion characteristics of the moving platform 6.

[0021] In summary, all of the above transmissions are achieved by the elastic deformation of the suspension plates and the connecting plates, and the translation effect of the moving platform 6 is achieved without any kinematic pairs. It does not contain kinematic pairs, and all transmissions are not achieved by kinematic pairs, so there are no friction and wear phenomena in the transmission process of any kinematic pairs. Therefore, there is no need for workers to perform high-frequency maintenance and debugging, truly achieving 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. Finally, it should be noted that the above embodiments are only examples for clearly explaining 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 variations can be made based on the above description. It is impossible to enumerate all the implementation manners here, and the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
