Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an electric actuator with an installation auxiliary structure. Background Technique

[0002] An electric actuator is a driving device that can provide linear or rotational motion. It uses a certain driving energy and works under the action of a certain control signal. The actuator uses liquid, gas, electricity or other energy and converts it into a driving action through a motor, cylinder or other devices.

[0003] Chinese Patent Publication No. CN220016255U discloses an electric actuator with an installation auxiliary structure, including an electric actuator body and a bottom mounting seat, and further including an auxiliary mounting mechanism. The auxiliary mounting mechanism includes guide bars, a transverse connecting plate, a limiting plate, a connecting cylinder, a connecting rod, a contact floor plate and a side support plate. The bottom mounting seat is installed at the lower housing seat of the electric actuator body, and the auxiliary mounting mechanism is arranged outside the electric actuator body. The auxiliary mounting mechanism can be clamped to support the electric actuator body and keep the bottom mounting seat of the electric actuator body facing away from the ground. Then, the worker can insert the shaft rod of the valve downward into the bottom mounting seat and use bolts to lock the connection between the bottom mounting seat and the mounting seat outside the valve rod body to complete the auxiliary assembly of the electric actuator body and the valve. With the help of the auxiliary mounting mechanism, the auxiliary support assembly during the installation of the electric actuator body and the valve can be realized, and the electric actuator body can be prevented from being directly placed on the ground and being damaged by friction during installation.

[0004] However, in the above patent, the installation method is not optimized. It mainly completes the auxiliary assembly of the electric actuator body and the valve by the worker inserting the shaft rod of the valve downward into the bottom mounting seat and using bolts to lock the connection between the bottom mounting seat and the mounting seat outside the valve rod body. With the help of the auxiliary mounting mechanism, the auxiliary support assembly during the installation of the electric actuator body and the valve can be realized.

[0005] The existence of such an auxiliary mechanism will not only reduce the installation efficiency of the electric actuator, but also greatly increase the installation cost. Content of the Utility Model

[0009] Further, the fixing clamp includes two arc-shaped strip plates, connecting plates are arranged at the top ends of both the arc-shaped strip plates, and the top ends of the connecting plates are fixedly connected to the outer side wall of the octagonal connecting rod.

[0010] Further, the inner arc surfaces of the two arc-shaped strip plates face each other, and locking holes are opened at the ends of both the arc-shaped strip plates far away from the connecting plates.

[0011] Further, a positioning groove is opened on the side wall of the arc-shaped plate, and the position of the positioning groove corresponds to the position of the connecting plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will further describe the present invention in detail with reference to the accompanying drawings.

[0027] Embodiment:

[0028] Referring toFigures 1 - 6 , an electric actuator with an installation auxiliary structure disclosed by the utility model includes a motor bracket 1. An actuator motor 2 is arranged inside the motor bracket. Extension rods 3 are arranged on both sides of the bottom end of the motor bracket 1. An arc-shaped plate 4 is arranged at the bottom end of the extension rod 3. A fixing ring 5 is arranged on one side of the arc-shaped plate 4. An octagonal connecting rod 6 is inserted into the inside of the fixing ring 5. Fixed clamps 7 are fixedly arranged on both sides of the bottom end of the octagonal connecting rod 6.

[0029] In this embodiment, when installing the electric actuator, the two octagonal connecting rods 6 are respectively drawn out from the inside of the fixing ring 5, and then the fixed clamps 7 are sleeved on both sides of the pipeline valve, and the linear directions of the two octagonal connecting rods 6 are perpendicular to the linear direction of the pipeline valve rotating shaft, as Figure 1 shown. When the motor bracket 1 is inserted into one end of the two octagonal connecting rods 6 through the fixing ring 5 and the actuator motor 2 is connected to the pipeline valve rotating shaft, the purpose of installing and fixing the electric actuator is achieved at this time. When the pipeline valve rotating shaft is perpendicular to the horizontal plane, it can provide better support for the motor bracket 1, thereby achieving the effect of improving the safety of the motor;

[0030] Furthermore, when installing the electric actuator, the two fixed clamps 7 are respectively fixed on one side of the pipeline valve and the installation position of the pipeline valve shaft rod, as Figure 2 shown. And the linear directions of the two octagonal connecting rods 6 are perpendicular to the linear direction of the pipeline valve. Then the motor bracket 1 is installed at one end of the octagonal connecting rod 6 through the fixing ring 5, and the actuator motor 2 is connected to the pipeline valve rotating shaft, achieving the effect of fixing the electric actuator, and the axis line of the motor bracket 1 can be accurately aligned with the axis line of the pipeline valve rotating shaft, so as to facilitate the alignment of the motor shaft of the actuator motor 2 with the pipeline valve rotating shaft when the pipeline rotating shaft direction is parallel to the horizontal plane direction;

[0031] Compared with the prior art, it can effectively change the installation method of the electric actuator, enable the electric actuator to be accurately installed at the position of the valve shaft, and the installation is convenient. Different installation methods can be replaced according to different usage situations, which can effectively improve the installation efficiency and the convenience of installation.

[0032] In a further preferred embodiment of the utility model, as Figures 1 - 6 shown, the fixed clamp 7 includes two arc-shaped strip plates 71. Connecting plates 72 are arranged at the top ends of the two arc-shaped strip plates 71. The top ends of the connecting plates 72 are fixedly connected to the outer side wall of the octagonal connecting rod 6.

[0033] In this embodiment, through the arrangement of the two connecting plates 72, the two arc-shaped strip plates 71 are installed on both sides of the octagonal connecting rod 6, so that the two arc-shaped strip plates 71 form a ring to facilitate clamping on the outer peripheral side of the pipeline.

[0034] In a further preferred embodiment of the present utility model, as Figures 1 - 6 shown, the inner arc surfaces of the two arc-shaped strip plates 71 face each other, and locking holes 73 are formed at one ends of the two arc-shaped strip plates 71 away from the connecting plate 72.

[0035] In this embodiment, since the inner arc surfaces of the two arc-shaped strip plates 71 face each other, the two arc-shaped strip plates 71 can be buckled on the outer surface of the pipeline. Through the arrangement of the locking holes 73, when the two arc-shaped strip plates 71 are jointly sleeved on the outer surface of the pipeline, the lower sides of the two arc-shaped strip plates 71 are fixed by bolts, so as to achieve the effect of improving the stability on the pipeline surface.

[0037] In this embodiment, when the fixed clamp 7 is fixed at the installation position of the pipeline valve shaft rod, each connecting plate 72 at the top end of the arc-shaped strip plate 71 will be stuck into the inside of the positioning groove 8, and the bottom protrusion of the arc-shaped strip plate 71 will be stuck into the inside of the positioning groove 8 of another arc-shaped plate 4, as Figure 5 shown. Therefore, when the linear direction of the pipeline valve rotating shaft is parallel to the horizontal direction, the stability of the arc-shaped strip plate 71 can be further improved, so as to achieve the effect of improving the stability of the electric actuator during operation.

[0038] In a further preferred embodiment of the present utility model, as Figures 1 - 6 shown, a fixing hole 9 is formed at the bottom end of the fixing ring 5, and a threaded hole 10 is formed at a position of the octagonal connecting rod 6 corresponding to the fixing hole 9.

[0039] In this embodiment, through the arrangement of the threaded hole 10 and the fixing hole 9, when the octagonal connecting rod 6 is inserted into the inside of the fixing ring 5, a screw can be inserted into the fixing hole 9 and screwed into the threaded hole 10, so as to achieve the effect of fixedly connecting the octagonal connecting rod 6 and the fixing ring 5, and threaded holes 10 are formed on eight surfaces of the outer surface of the octagonal connecting rod 6.

[0040] In a further preferred embodiment of the present utility model, as Figures 1 - 6 shown, a coupling 11 is arranged at the motor shaft of the actuating motor 2.

[0041] In this embodiment, through the arrangement of the coupling 11, it is convenient to connect the motor shaft of the actuating motor 2 with the pipeline valve rotating shaft, and when the actuating motor 2 is installed inside the motor bracket 1, the axis line of the motor shaft of the actuating motor 2 and the axis line of the motor bracket 1 are on the same straight line.
