Description

Technical Field

[0001] This utility model relates to the field of slag discharge machines, and in particular to a hydraulic automatic tensioning device at the tail of a slag discharge machine. Background Technology

[0002] A slag remover is a boiler slag removal device used to process high-temperature ash and slag after boiler combustion. Through crushing, cooling, and conveying processes, it pulls the ash and slag from the slag storage pit outside the furnace. Common models include the KCH heavy-duty frame chain slag remover, chain bucket slag remover, and spiral slag remover. This equipment is widely used in industrial boilers, power plant boilers, and waste-to-energy plants.

[0003] The core objective of tension adjustment at the tail of the slag discharger is to maintain appropriate tension in the conveyor chain and steel belt to prevent chain slippage, jamming, chain breakage, scraper tilting, or increased wear, thus ensuring continuous and stable operation. Adjusting the tension at the tail of the slag discharger through a hydraulic structure can effectively improve the stability and reliability of the equipment operation. Utility Model Content

[0004] In view of this, the present invention provides a hydraulic automatic tensioning device for the tail of a slag discharger. The main technical problem to be solved is: to provide a hydraulic automatic tensioning device for the tail of a slag discharger that adjusts the tension of the tail of the slag discharger through a hydraulic structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic automatic tensioning device for the tail end of a slag discharger, comprising a slag discharger body, a tail rotation mechanism installed at the tail end of the slag discharger body, and a tail tensioning adjustment mechanism installed at the tail end of the slag discharger body. The slag discharger body includes a frame, and a fixed frame is fixedly connected to the tail end of the frame. The tail tensioning adjustment mechanism is located below the tail rotation mechanism. The tail rotation mechanism includes a rotating shaft, and bearing seats are installed at both ends of the rotating shaft. The tail tensioning adjustment mechanism includes a hydraulic rod and a threaded rod. There are two sets of hydraulic rods, which are located at the left and right ends of the rotating shaft, respectively. The hydraulic rods are installed inside the frame, and the threaded rods are installed inside the fixed frame. A connecting plate is installed on the threaded rod, and the top of the hydraulic rod is fixedly connected to the bottom of the connecting plate. A movable plate is also installed on the threaded rod, and the movable plate is located above the connecting plate. A spring is provided between the connecting plate and the movable plate, and an installation groove is opened in the movable plate. The bearing seats are installed inside the installation groove.

[0006] By adopting the above technical solution, during use, the hydraulic rod controls the up-and-down movement of the connecting plate and the moving plate, thereby controlling the up-and-down movement of the bearing seat installed in the mounting groove, so that the rotating shaft can move up and down. When the rotating shaft moves down, the stretch length of the conveyor belt shortens, and the conveyor belt will relax. When the rotating shaft moves up, the stretch length of the conveyor belt increases, and the conveyor belt will tighten. After the hydraulic rod controls the up-and-down movement of the connecting plate and the moving plate, the position of the connecting plate and the moving plate can be fixed by adjusting the position of multiple nuts on the threaded rod, so that the rotating shaft can be kept in the adjusted position for operation.

[0007] As a further description of the above technical solution:

[0008] The head of the frame is equipped with a head drive assembly, which includes a drive motor, a belt, and a head shaft. The head shaft is installed at the head of the frame, the drive motor is installed inside the frame, the output end of the drive motor is provided with a first pulley, the end of the head shaft is provided with a second pulley, and a belt is installed between the first pulley and the second pulley.

[0009] By adopting the above technical solution, the drive motor drives the first pulley to rotate, which in turn drives the second pulley to rotate, so that the head shaft can rotate. When the head shaft rotates, it can drive the conveyor belt to move, and thus drive the ash and slag to move.

[0010] As a further description of the above technical solution:

[0011] A conveyor belt is installed between the head drive assembly and the tail rotation mechanism. The surface of the conveyor belt is provided with multiple partitions, and the conveyor belt is mounted on the rotating shaft via mounting wheels.

[0012] By adopting the above technical solution, the conveyor belt is installed on the head drive assembly and the tail rotation mechanism, and the head drive assembly drives the conveyor belt to move.

[0013] As a further description of the above technical solution:

[0014] The frame is equipped with multiple sets of guide components, each including a guide shaft and a connecting bearing. The guide shaft is mounted inside the frame via the connecting bearing.

[0015] By adopting the above technical solution, the direction of movement of the conveyor belt can be changed through multiple sets of guiding components, thereby facilitating the transportation of ash and slag by the main body of the slag discharge machine.

[0016] As a further description of the above technical solution:

[0017] The bearing housing contains a bearing, and the end of the shaft is mounted inside the bearing.

[0018] By adopting the above technical solution, the rotating shaft can rotate within the bearing housing through the bearing, which facilitates the movement of the conveyor belt.

[0019] As a further description of the above technical solution:

[0020] A controller is installed at the rear of the frame, and the controller is connected to the signal end of the hydraulic rod via a wire.

[0021] By adopting the above technical solution, the hydraulic rod can be controlled by the controller to work, and with the help of the PLC program, the automatic tensioning of the tail of the slag discharge machine can be achieved.

[0022] By employing the above technical solution, the hydraulic automatic tensioning device at the tail of the slag discharge machine of this utility model has at least the following beneficial effects:

[0023] 1. Compared with the existing technology, the hydraulic automatic tensioning device at the tail of the slag discharge machine, through the cooperative design of the hydraulic rod and the threaded rod, can adjust the position of the rotating shaft in the tail rotating mechanism up and down, thereby controlling the tension of the conveyor belt. At the same time, the connection between the controller and the hydraulic rod enables the entire tension adjustment process to be automated, further improving the intelligence level of the equipment, reducing manual intervention, and lowering the difficulty of operation and labor intensity.

[0031] Reference Figure 1-5This utility model provides a hydraulic automatic tensioning device for the tail end of a slag discharger: It includes a slag discharger body 1, a tail rotation mechanism 2 installed at the tail end of the slag discharger body 1, and a tail tensioning adjustment mechanism 3 installed at the tail end of the slag discharger body 1. The slag discharger body 1 includes a frame 101, and a fixing frame 105 is fixedly connected to the tail end of the frame 101. The tail tensioning adjustment mechanism 3 is located below the tail rotation mechanism 2. The tail rotation mechanism 2 includes a rotating shaft 201, and bearing seats 203 are installed at both ends of the rotating shaft 201. The tail tensioning adjustment mechanism 3 includes hydraulic rods 301 and threaded rods 303. The number of hydraulic rods 301 is two sets. Hydraulic rods 301 are located at the left and right ends of the rotating shaft 201. The hydraulic rods 301 are installed inside the frame 101. Threaded rods 303 are installed inside the fixed frame 105. Multiple adjustable nuts are provided on the threaded rods 303. A connecting plate 302 is installed on the threaded rods 303. The top of the hydraulic rods 301 is fixedly connected to the bottom of the connecting plate 302. A movable plate 304 is also installed on the threaded rods 303, located above the connecting plate 302. A spring 305 is provided between the connecting plate 302 and the movable plate 304. The tension of the conveyor belt 104 can be obtained by detecting the state of the spring 305. When the connecting plate 305... When position 02 is fixed, under the action of spring 305, the greater the distance between connecting plate 302 and moving plate 304, the smaller the tension of surface conveyor belt 104. The length of spring 305 is inversely proportional to the tension of conveyor belt 104; the longer spring 305 is, the looser the conveyor belt 104. The state of spring 305 can be detected by an external distance detection sensor, mainly detecting the distance between moving plate 304 and connecting plate 302. A mounting groove 306 is provided in moving plate 304, and bearing seat 203 is installed inside the mounting groove 306. In use, the hydraulic rod 301 controls the movement of connecting plate 302 and moving plate 304. The hydraulic rod 301 moves up and down, thereby controlling the bearing seat 203 installed in the mounting groove 306 to move up and down, so that the rotating shaft 201 can move up and down. When the rotating shaft 201 moves down, the stretch length of the conveyor belt 104 becomes shorter, and the conveyor belt 104 will relax. When the rotating shaft 201 moves up, the stretch length of the conveyor belt 104 becomes longer, and the conveyor belt 104 will tighten. After the hydraulic rod 301 controls the connecting plate 302 and the moving plate 304 to move up and down, the positions of the multiple nuts on the threaded rod 303 can be adjusted to fix the positions of the connecting plate 302 and the moving plate 304, so that the rotating shaft 201 can be kept in the adjusted position for operation.

[0032] A head drive assembly 102 is mounted at the head of the frame 101. The head drive assembly 102 includes a drive motor, a belt, and a head shaft. The head shaft is mounted at the head of the frame 101, and the drive motor is mounted inside the frame 101. A first pulley is provided at the output end of the drive motor, and a second pulley is provided at the end of the head shaft. A belt is installed between the first pulley and the second pulley. The drive motor drives the first pulley to rotate, and the belt, in turn, drives the second pulley to rotate, enabling the head shaft to rotate. When the head shaft rotates, it can drive the conveyor belt 104 to move. This drives the ash and slag to move. A conveyor belt 104 is installed between the head drive assembly 102 and the tail rotating mechanism 2. The surface of the conveyor belt 104 is provided with multiple partitions. The conveyor belt 104 is mounted on the rotating shaft 201 through the mounting wheel 202. The conveyor belt 104 is mounted on the head drive assembly 102 and the tail rotating mechanism 2. The head drive assembly 102 drives the conveyor belt 104 to move. A bearing is installed inside the bearing seat 203. The end of the rotating shaft 201 is installed in the bearing. The rotating shaft 201 can rotate in the bearing seat 203 through the bearing, which facilitates the movement of the conveyor belt 104.

[0033] The frame 101 is equipped with a guide assembly 103. There are multiple sets of guide assemblies 103. Each guide assembly 103 includes a guide shaft and a connecting bearing. The guide shaft is installed inside the frame 101 through the connecting bearing. The multiple sets of guide assemblies 103 can change the movement direction of the conveyor belt 104, thereby facilitating the transportation of ash and slag by the slag discharge machine body 1.

[0034] A controller 307 is installed at the rear of the frame 101. The controller 307 is connected to the signal terminal of the hydraulic rod 301 via a wire. The controller 307 can be a Rexroth 4WREE6W32-114Q-21G24NEK31 / A1V (proportional valve controller), and the hydraulic rod can be a Rexroth CDH1MP5 / 80 / 45 / 100A1X / B1CGWW (engineering cylinder). The controller 307 can control the hydraulic rod 301 to work, start the system, acquire tension data (tension data can be obtained by detecting the state of spring 305), operate the hydraulic rod (the hydraulic rod extends when the value is less than the preset value, and retracts when the value is greater than the preset value), and stop the machine. The controller 307 can control the hydraulic rod 301 to work, and with the help of the PLC program, it can realize the automatic tensioning of the tail of the slag discharge machine.

[0035] Working principle: When the slag discharger starts running, the controller 307 first initiates the system for initialization, at which point the conveyor belt 104 is in its initial tension state. During operation, the tension data of the conveyor belt 104 is obtained by detecting the state of the spring 305. If the detected tension data is less than the preset value, it indicates that the conveyor belt 104 is too loose. The controller 307 then controls the hydraulic rod 301 to extend, pushing the connecting plate 302 and the moving plate 304 upward, which in turn drives the bearing seat 203 and the rotating shaft 201 to move upward, thus increasing the stretch length of the conveyor belt 104 and tightening it. If the detected tension data is greater than the preset value, it indicates that the conveyor belt 104 is too tight. The controller 307 then controls the hydraulic rod 301 to retract, causing the connecting plate 302 and the moving plate 304 to move downward, which in turn moves the rotating shaft 201 downward, shortening the stretch length of the conveyor belt 104 and loosening it. After the hydraulic rod 301 controls the connecting plate 302 and the moving plate 304 to move up and down to the appropriate position, the positions of the connecting plate 302 and the moving plate 304 are fixed by adjusting the positions of the multiple nuts on the threaded rod 303. This ensures that the rotating shaft 201 can be stably maintained in the adjusted position, ensuring that the conveyor belt 104 is always at a suitable tension, and ensuring the continuous and stable operation of the slag discharger. When the slag discharger needs to be stopped, the controller 307 controls the relevant components to stop working, completing the entire operation process.

[0036] 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.
