Description

Technical Field

[0001] This utility model relates to the technical field of limit switches for grate coolers, and in particular to a grate cooler with limit switches. Background Technology

[0002] The grate cooler is an important main equipment in the clinker calcination system of a cement plant. Its main function is to cool and transport cement clinker. The grate cooler equipment includes a grate bed, which moves back and forth while the grate cooler is running. Its main functions are to promote the movement of clinker, distribute materials evenly, and improve cooling efficiency.

[0003] When the grate bed on the grate cooler reciprocates, due to the structure of the equipment, its linear reciprocating motion will shift to the circumference during movement. This will cause fluctuations in the distance between the sensing plate on the grate bed and the limit switch, resulting in a deviation in the limit switch's sensing of the grate bed's reciprocating movement. Secondly, when the grate bed's vibration deviation is large, the limit switch may not be able to sense the sensing plate, affecting the use of the limit switch. After the grate bed's movement is not effectively restricted, it may hit the limit switch with a large impact and cause damage to it.

[0004] Based on the above situation, it is necessary to design a grate cooler with limit switches to solve the above problems. Utility Model Content

[0005] This invention provides a grate cooler with a limit switch to solve the problem in the prior art where the limit switch does not effectively sense the induction plate when the grate moves back and forth.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A grate cooler with limit switches includes a grate body and two pads connected below the grate body, each pad having a sensing element; a mounting plate disposed below the grate body, the mounting plate having a switch body with its sensing end facing the grate body and its axis perpendicular to the surface of the mounting plate; and an adaptive mechanism disposed below the grate body and connected to the mounting plate, the adaptive mechanism being used to make the vibration amplitude of the mounting plate and the grate body consistent.

[0008] Preferably, the adaptive mechanism includes elastic elements disposed on both sides of the mounting plate and swing arms connected to the two elastic elements respectively, with the ends of the two swing arms away from the elastic elements respectively connected to the two sides of the mounting plate.

[0009] Preferably, the elastic element consists of a rotating wheel, a bearing component, and a telescopic component. The rotating wheel is rotatably connected to the bearing component, one end of the swing arm is hinged to the bearing component, and the telescopic component is connected to the bearing component and is used to support the bearing component.

[0010] Preferably, it also includes a fixing plate. The telescopic component includes a telescopic rod connected to a bearing component at one end, a sleeve connected to the fixing plate, and a spring sleeved on the outside of the telescopic rod.

[0011] Preferably, the mounting plate has a sliding groove, a lifting frame is vertically slidably connected in the sliding groove, the switch body is connected to the lifting frame, and the lifting frame has a wiring hole.

[0012] Preferably, the lifting frame has a plurality of linearly arranged positioning holes on both sides, and a pin hole plate is connected to the mounting plate, with the pin hole plate corresponding to the position of the positioning holes.

[0013] Preferably, both ends of the gasket are provided with chamfered portions.

[0014] The beneficial effects of this utility model are as follows: by setting a self-adaptive mechanism for installing the switch body under the grate, the mounting plate will vibrate up and down with the vibration of the grate. Therefore, the distance between the switch body and the sensing plate is always fixed and will not be affected by the up and down vibration of the grate.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-4 As shown, a grate cooler with a limit switch includes a grate body 1, two pads 2 connected below the grate body 1, a mounting plate 4 disposed below the grate body 1, and an adaptive mechanism disposed below the grate body 1 and connected to the mounting plate 4. Specifically, each of the two pads 2 is provided with a sensing plate 3, the two pads 2 are linearly arranged, and there is a certain distance between the two pads 2; a switch body 5 is provided on the mounting plate 4, and the sensing end of the switch body 5 faces the grate body 1, and the axis of its sensing end is perpendicular to the surface of the mounting plate 4; the adaptive mechanism is used to make the vibration amplitude of the mounting plate 4 and the grate body 1 consistent, thereby adjusting the limit switch. The distance between the switch body 5 and the pad 2 is maintained at the same distance, facilitating the sensing of the sensing plate 3 by the switch body 5. Because the sensing plate 3 has a certain length, when the grate body 1 vibrates left and right, the sensing plate 3 will not exceed the sensing range of the sensing end of the switch body 5. When the grate body 1 vibrates up and down, the mounting plate 4 will vibrate up and down with the grate body 1 under the action of the self-adaptive mechanism. Therefore, the distance between the switch body 5 and the sensing plate 3 is always fixed at this time, and the distance between the sensing plate 3 and the switch body 5 will not be affected by the up and down vibration of the grate body 1, thereby avoiding affecting the sensing accuracy of the sensing end of the switch body 5.

[0023] In use, first install the sensing plate 3 on the pad 2. Then, connect the two pads 2 to the bottom of the grate body 1 of the grate cooler and fix them in place. The distance between the two pads 2 is set according to the reciprocating distance of the grate body 1. Next, connect the mounting plate 4 and the switch body 5 to the frame of the grate cooler (not shown in the figure). When the grate cooler is running, its grate body 1 will reciprocate, which will drive the pads 2 and sensing plate 3 connected to the grate body 1 to reciprocate. The grate body 5 is stabilized on the frame of the grate cooler. Therefore, when the gasket 2 and the switch body 5 move relative to each other, that is, when the two gaskets 2 repeatedly mate with the sensing end of the switch body 5, when one of the sensing plates 3 mates with the sensing end of the switch body 5, the sensing end of the switch body 5 will sense the sensing plate 3 and generate a position signal. This signal will be processed by the background system to generate a control command. This control command will control the moving grate body 1 to stop moving forward and then move the grate body 1 in the opposite direction. After moving a certain distance, the sensing plate 3 on the other pad 2 will dock with the sensing end of the switch body 5, generating a position signal again. This position signal, processed by the background system, will control the moving grate body 1 to stop moving forward and then move the grate body 1 in the opposite direction. This cycle repeats. Under the sensing of the switch body 5, the grate body 1 will reciprocate over a fixed distance. During this process, to ensure that the positional relationship between the switch body 5 and the sensing plate 3 does not deviate and to accurately measure the reciprocating distance of the grate body 1, the adaptive mechanism ensures that the sensing end of the switch body 5 is parallel to the sensing plate 3 when docking. The switch body 5 vibrates along with the vibration of the grate body 1. Therefore, the switch body 5 and the sensing plate 3 are always at a fixed distance, improving the sensing accuracy of the switching body 5, ensuring the timeliness of signal sensing, and accurately measuring the reciprocating distance of the grate body 1.

[0024] The system also includes a fixing plate 20, which is used to install on the frame of the grate cooler. The frame is an existing technology structure and will not be described in detail. Its main function is to provide a fixed carrier for the fixing plate 20. The adaptive mechanism is provided on the elastic elements 6 on both sides of the mounting plate 4 and the swing arms 7 connected to the two elastic elements 6 respectively. The ends of the two swing arms 7 away from the elastic elements 6 are respectively connected to the two sides of the mounting plate 4. When the elastic element 6 contacts the gasket 2, the elastic element 6 will vibrate with the vibration of the gasket 2, and then the elastic element 6 will drive the swing arms 7 to move synchronously, thereby driving the synchronous movement of the mounting plate 4.

[0025] Furthermore, to ensure that the elastic element 6 makes smooth contact with the gasket 2 without generating a large vibration amplitude, the elastic element 6 is composed of a rotating wheel 8, a bearing 9, and a telescopic element 10. The rotating wheel 8 is rotatably connected to the bearing 9, one end of the swing arm 7 is hinged to the bearing 9, and the telescopic element 10 is connected to the bearing 9 and used to support the bearing 9. When the elastic element 6 contacts the gasket 2, its rotating wheel 8 will first contact the gasket 2, and then rotate with the movement of the grate body 1. Then, under the action of the telescopic element 10, the rotating wheel 8 will move vertically, and the rotating wheel 8 will always be in contact with the surface of the gasket 2. The design of the rotating wheel 8 also reduces the friction between the elastic element 6 and the gasket 2, avoiding damage to the gasket 2.

[0026] The telescopic component 10 includes a telescopic rod 11 connected to the bearing component 9 at one end, a sleeve 13 connected to the fixed plate 20, and a spring 12 sleeved on the outside of the telescopic rod 11. The other end of the telescopic component 10 is slidably connected inside the sleeve 13. The two ends of the spring 12 are respectively connected to the telescopic rod 11 and the sleeve 13. When the telescopic rod 11 slides on the sleeve 13, under the action of the spring 12, the sliding of the telescopic rod 11 will be in a state of elastic contraction and release.

[0027] Furthermore, in order to facilitate the installation and adjustment of the switch body 5, a sliding groove 14 is provided on the mounting plate 4. A lifting frame 15 is vertically slidably connected in the sliding groove 14. The switch body 5 is connected to the lifting frame 15. A wiring hole 16 is provided on the lifting frame 15. The wiring hole 16 facilitates the connection of the wire to the wiring port of the switch body 5, so that the wire is not tangled or squeezed by the lifting frame 15.

[0028] Furthermore, in order to position the lifting frame 15 and make it stable, several positioning holes 17 are linearly arranged on both sides of the lifting frame 15. A pin hole plate 18 is connected to the mounting plate 4, and the pin hole plate 18 corresponds to the position of the positioning hole 17. In use, a bolt is used, one end of the bolt is passed through the pin hole plate 18 and inserted into the corresponding positioning hole 17, and the lifting frame 15 will be fixed.

[0029] Finally, in order to facilitate the rotating wheel 8 to travel onto the surface of the gasket 2 with a smaller vibration amplitude, chamfered portions 19 are provided at both ends of the gasket 2 to buffer the thickness at both ends of the gasket 2.
