Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a valve body placing device. Background Art

[0002] The valve body is the main structural part of the valve. It bears all the components inside the valve and controls the flow of fluid in different ways. The valve body is usually made of metal materials to withstand high pressure, high temperature or corrosive environments;

[0003] However, during the installation of the existing valve body, in order to ensure its accurate installation position, a placing device with a clamping function needs to be set up. The design and function of this device are aimed at ensuring that the valve body can be accurately and conveniently placed into the pipeline system and can be correctly positioned and fixed at its designed position.

[0004] However, most of the existing placing devices use electric push rods to fix the valve body by clamping it from both sides. However, since the valve body is mainly used to control the flow of the pipeline, when clamping the valve body, it is necessary to ensure that the clamping force is just right to avoid deformation and damage of the valve body. Even slight deformation of the valve body may cause liquid leakage.

[0005] Therefore, the utility model proposes a valve body placing device. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a valve body placing device.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: A valve body placing device includes an installation main body seat, a power arm and an auxiliary arm. The power arm and the auxiliary arm are both rotatably connected to the installation main body seat. The other sides of the power arm and the auxiliary arm are both rotatably connected with clamping arms. The connections between the power arm and the auxiliary arm and the clamping arms are both rotatably connected with connecting arms. The other ends of the two connecting arms are both rotatably connected to the installation main body seat. An installation component is arranged on the other side of the installation main body seat, and a driving component is arranged at the bottom of the installation main body seat;

[0008] The driving component includes a driving seat which is rotatably connected to the installation main body seat. The driving seat is meshed with the power arm. A connecting gear is arranged at the bottom of the driving seat. A driving gear is rotatably connected to the installation main body seat on one side of the connecting gear. A connecting belt is wound around the connecting gear and the driving gear.

[0009] As a preferred implementation manner, a driving motor is arranged below the driving gear on the installation main body seat, and the output end of the driving motor is connected to the driving gear.

[0010] The beneficial effects of adopting the above further solution are as follows: The driving motor provides power for the rotation of the driving gear, and under the action of the connecting belt, when the driving gear rotates, it drives the connecting gear to rotate, thereby adjusting the opening and closing state of the power arm and the auxiliary arm.

[0011] As a preferred embodiment, the mounting assembly includes a spherical seat and a movable seat. The spherical seat is movably connected within the movable seat. A groove is provided on the spherical seat, a threaded hole is provided on the movable seat, and a flange is provided on the other side of the movable seat.

[0012] The beneficial effects of adopting the above further solution are as follows: Under the action of the flange, the mounting assembly is connected and fixed to the power mechanism. The power mechanism is responsible for adjusting the front, rear, left, and right displacements of the valve body after clamping and fixing. Further, the spherical seat is movably connected within the movable seat, so that when the valve body is placed, the placement angle of the valve body can be finely adjusted. By inserting the limit bolt through the threaded hole and into the groove, the spherical seat is limited, preventing the spherical seat and the movable seat from rotating and displacing after adjusting the placement angle of the valve body, resulting in inaccurate installation angle.

[0013] As a preferred embodiment, tooth grooves are provided at the ends of the power arm and the auxiliary arm that are close to each other, and the power arm and the auxiliary arm are meshed and connected through the tooth grooves.

[0014] The beneficial effects of adopting the above further solution are as follows: Tooth grooves are provided on both the power arm and the auxiliary arm. Through the design of the tooth grooves, the power arm and the auxiliary arm can be meshed and connected, so that when the driving component drives the power arm to rotate, the auxiliary arm will also rotate accordingly. At this time, the power arm and the auxiliary arm are in an open and closed state.

[0015] As a preferred embodiment, limit rings and limit hooks are provided on the sides of the two clamping arms that are away from each other. There are two limit rings in total, and the two limit rings are symmetric with respect to the center of the clamping arm.

[0016] The beneficial effects of adopting the above further solution are as follows: The limit rope is limited by the limit ring, avoiding the limit rope being too close during use and reducing the limit width. Further, under the action of the limit hook, the limit rope is limited to prevent the limit rope from separating from the clamping arm during use.

[0017] As a preferred embodiment, a limit rope is provided on the four limit rings, and both ends of the limit rope are connected to the two limit hooks respectively.

[0018] The beneficial effects of adopting the above further solution are as follows: The valve body is assisted in being limited by the limit rope, avoiding the valve body separating from the clamping arm and falling off when the opening and closing amplitude of the power arm and the auxiliary arm is too large and the clamping force is weak, resulting in damage to the valve body due to knocking.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0020] 1. In the present utility model, by starting the driving motor to drive the driving gear to rotate, at this time, under the action of the connecting belt, the connecting gear also rotates accordingly. However, when the connecting gear rotates, it drives the meshing rotation between the driving seat and the power arm, so that the power arm and the auxiliary arm expand or contract to both sides, thereby realizing the clamping and limiting of the valve body. But when the power arm and the auxiliary arm are in the clamping state, under the action of the connecting belt, even if the driving gear continues to rotate, the power arm and the auxiliary arm will not apply excessive pressure to the valve body. Since the driving gear and the connecting gear are connected by the connecting belt, when the power arm and the auxiliary arm clamp the valve body to a certain strength, the rack in the connecting belt will be misaligned with the tooth grooves on the driving gear and the connecting gear, thus avoiding damage to the valve body during the clamping process.

[0021] 2. In the present utility model, through the setting of the flange plate, the installation component is connected and fixed with the power mechanism. The power mechanism is responsible for adjusting the front, back, left, and right displacements of the valve body after clamping and fixing. Further, it can be movably connected through the spherical seat in the movable seat, so that when the valve body is placed, the placement angle of the valve body can be finely adjusted. By inserting the limiting bolt into the groove through the threaded hole, the spherical seat is limited to prevent the spherical seat from rotating and displacing between the movable seat after adjusting the placement angle of the valve body, resulting in inaccurate installation angle.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1-5As shown in the figure, the present utility model provides a technical solution: a valve body placing device, which includes an installation main body seat 1, a power arm 11 and an auxiliary arm 12. The power arm 11 and the auxiliary arm 12 are both rotatably connected to the installation main body seat 1. On the other side of the power arm 11 and the auxiliary arm 12, a clamping arm 14 is rotatably connected. At the connection between the power arm 11 and the auxiliary arm 12 and the clamping arm 14, a connecting arm 13 is rotatably connected. The other ends of the two connecting arms 13 are rotatably connected to the installation main body seat 1. On the other side of the installation main body seat 1, an installation component 2 is provided. At the bottom of the installation main body seat 1, a driving component 3 is provided; the driving component 3 includes a driving seat 31, the driving seat 31 is rotatably connected to the installation main body seat 1, and there is a meshing connection between the driving seat 31 and the power arm 11. At the bottom of the driving seat 31, a connecting gear 32 is provided. On the installation main body seat 1, a driving gear 33 is rotatably connected on one side of the connecting gear 32. A connecting belt 35 is wound around the connecting gear 32 and the driving gear 33. Below the driving gear 33 on the installation main body seat 1, a driving motor 34 is provided. The output end of the driving motor 34 is connected to the driving gear 33. Tooth grooves are provided at the ends of the power arm 11 and the auxiliary arm 12 that are close to each other. The power arm 11 and the auxiliary arm 12 are meshed through the tooth grooves. By starting the driving motor 34 to drive the driving gear 33 to rotate, at this time, under the action of the connecting belt 35, the connecting gear 32 also rotates. But when the connecting gear 32 rotates, it drives the meshing rotation between the driving seat 31 and the power arm 11, so that the power arm 11 and the auxiliary arm 12 expand or contract to both sides, thereby realizing the clamping and limiting of the valve body. However, when the power arm 11 and the auxiliary arm 12 are in the clamping state, under the action of the connecting belt 35, even if the driving gear 33 continues to rotate, the power arm 11 and the auxiliary arm 12 will not apply too much pressure to the valve body. Since the driving gear 33 and the connecting gear 32 are connected by the connecting belt 35, when the power arm 11 and the auxiliary arm 12 clamp the valve body to a certain strength, the rack in the connecting belt 35 will be misaligned with the tooth grooves on the driving gear 33 and the connecting gear 32, thereby avoiding damage to the valve body during the clamping process, and solving the technical problem of damage to the valve body during the clamping process.

[0033] Further, as Figure 1 - Figure 3As shown in the figure: The installation component 2 includes a spherical seat 21 and a movable seat 23. The spherical seat 21 is movably connected within the movable seat 23. A groove 22 is provided on the spherical seat 21, and a threaded hole 25 is provided on the movable seat 23. A flange 24 is provided on the other side of the movable seat 23. Through the setting of the flange 24, the installation component 2 is fixedly connected to the power mechanism. The power mechanism is responsible for adjusting the front, back, left, and right displacements of the valve body after clamping and fixing. Further, through the movable connection of the spherical seat 21 within the movable seat 23, the placement angle of the valve body can be finely adjusted when the valve body is placed. By inserting the limit bolt through the threaded hole 25 and into the groove 22, the spherical seat 21 is limited, preventing the spherical seat 21 from rotating and displacing between the movable seat 23 after adjusting the placement angle of the valve body, resulting in inaccurate installation angles, and solving the technical problem of inaccurate placement angles of the valve body.

[0034] There is also a problem of limiting the binding of the limiting rope 15 in the above solution, such as Figure 5 As shown in the figure: On the sides of the two clamping arms 14 that are away from each other, limit rings 16 and limit hooks 17 are provided. There are two limit rings 16 in total, and the two limit rings 16 are symmetric with respect to the center of the clamping arm 14. The limit rope 15 is limited through the limit ring 16 to avoid the limit rope 15 being too close during use, reducing the limit width. Further, under the action of the limit hook 17, the limit rope 15 is limited to prevent the limit rope 15 from separating from the clamping arm 14 during use.

[0035] There is also a problem that when the power arm 11 and the auxiliary arm 12 open and close too much, the valve body is likely to fall off in the above solution, such as Figure 5 As shown in the figure: Limit ropes 15 are provided on the four limit rings 16. The two ends of the limit rope 15 are respectively connected to the two limit hooks 17. The valve body is assisted in being limited through the limit rope 15 to avoid the power arm 11 and the auxiliary arm 12 having too large an opening and closing amplitude, and when the clamping force is weak, the valve body separates from the clamping arm 14 and falls off, resulting in damage to the valve body due to collision.

[0036] Working principle:

[0037] Such as Figures 1-5As shown in the figure, the mounting assembly 2 is fixedly connected to the power mechanism through the flange 24. The power mechanism is responsible for adjusting the front-back, left-right displacement of the valve body after clamping and fixing. Further, the spherical seat 21 is movably connected within the movable seat 23, so that when the valve body is placed, the placement angle of the valve body can be finely adjusted. By inserting the limit bolt through the threaded hole 25 and into the groove 22, the spherical seat 21 is limited. Further, by starting the drive motor 34 to drive the drive gear 33 to rotate, at this time, under the action of the connecting belt 35, the connecting gear 32 also rotates accordingly. But when the connecting gear 32 rotates, it drives the meshing rotation between the drive seat 31 and the power arm 11, so that the power arm 11 and the auxiliary arm 12 expand or contract to both sides, thereby realizing the clamping and limiting of the valve body. After the limiting is completed, the valve body is moved to the specified position for installation through the power mechanism.

[0038] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
