Description

Technical Field

[0001] This utility model belongs to the technical field of electric actuators, specifically relating to an intelligent linear electric actuator. Background Technology

[0002] An actuator is a device in automation technology that receives control information and applies control effects to the controlled object. Electric actuators are an important component of electric control. They convert the DC unified electrical signal from the control instrument into an angle or displacement corresponding to the input signal to drive various types of control valves, thereby achieving continuous control of flow in the production process, or simply opening and closing valves to control the flow of fluid, thus achieving the purpose of automatic control of the production process. Therefore, it is necessary to design an intelligent linear electric actuator.

[0003] In most existing linear electric actuators, the support rod is fixed and not adjustable. This structural design makes the stroke of the valve stem connector fixed, which is not convenient for driving control valves of different depths to open and close. This results in unsatisfactory or loose opening and closing. At the same time, the connecting plate structure at the bottom of the electric actuator is also fixed and not adjustable, which is not conducive to connecting different types of control valves and reduces the applicability of the electric actuator. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent linear electric actuator with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An intelligent linear electric actuator includes an electric actuator body. Sleeve rods are fixedly installed on both sides of the bottom of the electric actuator body. Sleeves are slidably fitted on the bottom of the outer sides of the two sleeve rods. Adjustment components that cooperate with the sleeve rods are fitted and fixed on the top of the outer sides of the two sleeves. Connection and fixing components are fixedly installed on the bottom of the two sleeves.

[0007] As a further optimization of this utility model, the adjusting assembly includes multiple fixing holes opened on the opposite side of the two sleeve rods. The adjusting assembly also includes a fixing ring, which is fixedly fitted onto the top of the outer side of the two sleeves. Both sides of the fixing ring are slidably provided with fixing rods extending into the fixing holes. A fixing screw is rotatably installed on one end of the front of the fixing ring. An internally threaded sleeve block is fitted onto the external thread of the fixing screw. Both sides of the internally threaded sleeve block are hinged with hinge rods. The side of the two hinge rods away from the internally threaded sleeve block is hingedly connected to the side of the two fixing rods away from each other.

[0008] As a further optimization of this utility model, the connecting and fixing assembly includes a connecting plate, which is fixedly installed at the bottom of two sleeves. Guide rods are fixedly installed on both sides of the connecting plate. L-shaped fixing blocks are slidably fitted onto the outside of both guide rods. A fixing screw is rotatably installed on one end of the front of the connecting plate. An internal threaded sleeve is threaded onto the outside of the fixing screw. Hinged rods are hinged on both sides of the internal threaded sleeve. The ends of the two hinged rods away from the internal threaded sleeve are hinged to the front of the two L-shaped fixing blocks.

[0009] As a further optimization of this utility model, a shaft is fixedly installed at the bottom of the main body of the electric actuator, and a valve stem connector is fixedly installed at the bottom of the shaft. The two sides of the valve stem connector slide against the outside of the sleeve.

[0010] As a further optimization of this utility model, the front end of the first fixing screw and the front end of the second fixing screw are respectively provided with a second actuating block and a first actuating block, and the front ends of the second actuating block and the first actuating block are respectively provided with a two-line opening groove and a two-line opening groove.

[0011] As a further optimization of this utility model, hinge seats are installed on one front end of the two L-shaped fixing blocks and the side of the two fixing rods that are far apart from each other, as well as on both sides of the internal threaded sleeve block one and the internal threaded sleeve block two. The hinge seats cooperate with the hinge rod one and the hinge rod two.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the structural design of the adjustment component, can realize the height adjustment function of the sleeve and the sleeve rod, thereby facilitating the adjustment of the support height of the electric actuator body in the later stage. This allows for the modification of the stroke length when the shaft drives the valve stem connector, which is convenient for the opening and closing operations of different types of control valves. In turn, it ensures the flexibility and practicality of the electric actuator body in the later stage of driving, and ensures the accuracy of the control valve in the later stage.

[0014] 2. Through the structural design of the connecting and fixing components, this utility model facilitates the later fixed installation of the electric actuator body with connection plates of different types of control valves. This increases the convenience and practicality of the electric actuator body in later connection and use, ensuring the applicability of the electric actuator body in later use. There is no need to replace the connection plate. Moreover, the structural design is simple and reasonable, ensuring the convenience and flexibility of the operator in fixing the connection later.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 , Figure 2As shown, an intelligent linear electric actuator includes an electric actuator body 1. The electric actuator body 1 internally includes a control unit, a stepless speed regulator, an encoder, and input / output signals. The control unit adopts DC brushless drive technology and is divided into a control board and a display board. The control board is responsible for signal acquisition and processing, as well as driving the DC brushless motor. The display board is responsible for data exchange with the user. The stepless speed regulator menu allows setting the motor speed and deceleration distance. The encoder utilizes the Hall effect sensor inside the brushless DC motor to replace the traditional encoder for precise positioning. Input / output signals can be switched arbitrarily via the menu. A control panel is located on one end of the front of the electric actuator body 1. The device includes a display and control keys. A shaft 2, which mates with the device's interior, is fixedly installed at the bottom of the electric actuator body 1. A valve stem connector 3 is fixedly installed at the bottom of the shaft 2. The electric actuator body 1 can drive the shaft 2 to move the valve stem connector 3. The valve stem connector 3 facilitates connection and drive with an external valve. Sleeve rods 7 are fixedly installed on both sides of the bottom of the electric actuator body 1. Sleeves 6, which slidably fit against the outer sides of the valve stem connector 3, are mounted on the bottom of the outer sides of both sleeve rods 7. This sliding connection between the sleeve rods 7 and sleeves 6 allows for easy adjustment of the support height of the electric actuator body 1.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, the bottom of the electric actuator body 1 is equipped with an adjustment component 5 that is fixedly fitted onto the top of the outer sides of the two sleeves 6. The structural design of the adjustment component 5 enables the fixed limiting of the height of the sleeves 6 and the sleeve rods 7 during later adjustments. The adjustment component 5 includes multiple fixing holes 504 opened on the opposite side of the two sleeve rods 7. The adjustment component 5 also includes a fixing collar 503 that is fixedly fitted onto the top of the outer sides of the two sleeves 6. Fixing rods 505 are slidably inserted through both sides of the fixing collar 503, and the fixing rods 505 extend through the sleeves 6 to the fixing... The hole 504 is engaged with the hole. A fixing screw 502 is rotatably mounted on one end of the front of the fixing collar 503. An internal threaded sleeve block 501 is threaded onto one end of the outer side of the fixing screw 502. Hinged rods 500 are hinged to both sides of the internal threaded sleeve block 501. The ends of the two hinged rods 500 away from the internal threaded sleeve block 501 are hinged to the sides of the two fixing rods 505 away from each other. A toggle block 1 is fixedly mounted on one end of the front of the fixing screw 502. A slotted opening 1 is formed on one end of the true surface of the toggle block 1. This design facilitates the rotation of the fixing screw 502 by operators using an external drive tool and a slotted opening. The hinged limit of the hinged rod 500 prevents the internal threaded sleeve 501 from rotating with the fixing screw 502. During the rotation of the fixing screw 502, the internal threaded sleeve 501 drives the hinged rod 500 to expand. Then, the hinged rod 500 pulls the fixing rod 505 within the fixing collar 503, allowing the fixing rod 505 to disengage from the fixing hole 50. The internal fixing of sleeve rod 7 is released, and then sleeve rod 7 can be moved inside sleeve 6 by electric actuator body 1, thereby realizing the adjustment of the support height of electric actuator body 1. Later, the reverse rotation of fixing screw 2 502 can make internal threaded sleeve block 2 501 move in the opposite direction on its surface, and then drive hinge rod 2 500 to hinge and push fixing rod 505 to move inside fixing collar 503 and insert into fixing hole 504, finally completing the fixing of sleeve rod 7 height.

[0023] like Figure 1 , Figure 2As shown, a connecting and fixing assembly 4 is fixedly installed at the bottom of the two sleeves 6. The connecting and fixing assembly 4 enables the subsequent fixed installation of the electric actuator body 1 with the control valve. Furthermore, the structural design of the connecting and fixing assembly 4 facilitates the fixed connection of different types of control valves. The connecting and fixing assembly 4 includes a connecting plate 400, which is fixedly installed at the bottom of the two sleeves 6. Guide rods 405 are fixedly installed at the middle positions on both sides of the connecting plate 400. L-shaped fixing blocks 404 are slidably fitted onto the outside of both guide rods 405. A fixing screw 401 is rotatably installed at the middle position of one end of the front of the connecting plate 400. An internally threaded sleeve block 402 is threaded onto one end of the front of the fixing screw 401. Hinged rods 403 are hinged to both sides of the internally threaded sleeve block 402. The ends of the two hinged rods 403 away from the internally threaded sleeve block 402 are hinged to the front ends of the two L-shaped fixing blocks 404. A fixed actuating block 2 is installed. One end of the front of the actuating block 2 has a slot 2. Later, with the help of an external driving tool, the fixed screw 401 can be rotated through the slot 2. Then, through the limiting design of the hinge rod 403, the internal threaded sleeve 402 can move outside the fixed screw 401, thereby realizing the hinge expansion of the hinge rod 403. Then, the L-shaped fixing block 404 can be pulled by the hinge rod 403 to move outside the guide rod 405. At the same time, with the L-shaped structure design of the L-shaped fixing block 404, the fixed installation of the control valve connecting plate and the connecting plate 400 can be easily completed. Moreover, through this structural design, it is easy to install and connect different models of control valve connecting plates, thereby improving the applicability and flexibility of the electric actuator body 1 in the later installation and use. Furthermore, through the structural design of this component, the operator only needs to perform a single threading operation, which effectively improves the convenience and flexibility of the operator in the later disassembly and assembly.

[0024] It should be noted that, in use, this intelligent linear electric actuator allows the operator to first rotate the fixed screw 502. The hinge limit of the hinge rod 500 prevents the internal threaded sleeve 501 from rotating with the fixed screw 502. During the rotation of the fixed screw 502, the internal threaded sleeve 501 drives the hinge rod 500 to perform hinge expansion. Then, the hinge rod 500 pulls the fixed rod 505 to move inside the fixed collar 503, thereby disengaging the fixed rod 505. The fixing hole 504 releases the sleeve rod 7 from the inside, and then the sleeve rod 7 can be moved inside the sleeve 6 by the electric actuator body 1, thereby realizing the adjustment of the support height of the electric actuator body 1. Later, the fixing screw 502 is rotated in the opposite direction, so that the internal threaded sleeve block 501 moves in the opposite direction on its surface, and then the hinge rod 500 can be driven to hinge and push the fixing rod 505 to move inside the fixing collar 503 and insert into the fixing hole 504, and finally the height of the sleeve rod 7 is fixed.

[0025] Later, by rotating the fixed screw 401 and then limiting the hinge rod 403, the internal threaded sleeve 402 can move outside the fixed screw 401, thereby enabling the hinge expansion of the hinge rod 403. Then, the hinge rod 403 can pull the L-shaped fixing block 404 to move outside the guide rod 405. With the L-shaped structure design of the L-shaped fixing block 404, the fixed installation of the control valve connecting plate and the connecting plate 400 can be easily completed. This structural design also facilitates the installation and connection of connecting plates of different models of control valves, thereby improving the applicability and flexibility of the electric actuator body 1 in later installation and use. Furthermore, the structural design of this component means that the operator only needs to perform one thread tightening operation, effectively improving the convenience and flexibility of disassembly and assembly for later operators.

[0026] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
