Description

[Technical field]

[0001] The utility model relates to the technical field of pipeline clamping, in particular to a high-torque pipeline clamping positioner. [Background technology]

[0002] A large number of steel pipes (mainly square pipes) are needed in the construction of nuclear power plants. Since the steel pipes used in nuclear power plants are relatively heavy, they need to be transported by means of transport devices (such as work vehicles, etc.) during construction. In order for the transport device to be able to clamp the steel pipes, a pipe clamp is needed.

[0003] Of course, there are some pipe clamps in the prior art, such as a pipe clamp disclosed in the Chinese utility model patent CN202322618717.X, which can control the opening and closing angle of the clamping jaws through a connecting rod group, so as to adapt to pipes of different sizes. However, the existing pipe clamps usually do not have a displacement function, and the clamping force is relatively small, which brings inconvenience to actual use. In view of the above-mentioned problems, the inventor of this case conducted an in-depth study on the problem, and thus this case was created. [Contents of the utility model]

[0004] The technical problem to be solved by the utility model is to provide a high-torque pipe clamp positioner to solve the problem that the existing pipe clamps usually have no position change function and have a small clamping force, thus causing inconvenience in actual use.

[0005] The utility model is implemented as follows: a high torque pipe clamping positioner comprises a rotating seat, a rotating drive mechanism, a screw moving mechanism, a moving drive mechanism and a clamping body;

[0006] The rotating seat body is connected to the output end of the rotating drive mechanism; the screw moving mechanism is arranged on the side of the rotating seat body facing away from the rotating drive mechanism, the screw moving mechanism is threadedly connected with two clamping bodies, the two clamping bodies are arranged facing each other, and the moving drive mechanism is connected to the screw moving mechanism; the moving drive mechanism drives the screw moving mechanism to drive the two clamping bodies to move closer to or away from each other, and the rotating seat body is driven by the rotating drive mechanism to drive the screw moving mechanism, the moving drive mechanism and the clamping body to rotate and displace.

[0007] Furthermore, the two clamping bodies are both provided with rubber contact plates on the sides facing each other.

[0008] Furthermore, when the screw moving mechanism drives the two clamping bodies to move away from each other to the extreme position, the distance between the two rubber contact plates is greater than 200 mm; when the screw moving mechanism drives the two clamping bodies to move closer to each other to the extreme position, the distance between the two rubber contact plates is less than 50 mm.

[0009] Furthermore, the rotary drive mechanism includes a first drive motor, a reducer and a motor mounting seat; the first drive motor is mounted on the motor mounting seat, the output end of the first drive motor is connected to the reducer, and the output end of the reducer is connected to the middle part of the rotating seat body.

[0010] Furthermore, the reducer is a harmonic reducer.

[0011] Furthermore, the screw moving mechanism includes a screw body, a linear slide rail, a linear slider and a screw slider;

[0012] The screw body is arranged in the middle part of the side of the rotating seat body facing away from the rotating drive mechanism, and both ends of the screw body are rotatably connected to the rotating seat body through bearing supports; the rotating seat body is provided with the linear slide rails on both sides of the screw body, and the linear slide rails and the screw body are arranged parallel to each other; each of the clamping bodies is threadedly connected to the screw body through a screw slider, and the moving directions of the two screw sliders on the screw body are opposite; each of the clamping bodies is slidably connected to the linear slide rail through a linear slider.

[0013] Furthermore, the mobile drive mechanism includes a second drive motor and a synchronous belt; the second drive motor is installed on the rotating seat, and the output end of the second drive motor is connected to one end of the screw body through the synchronous belt.

[0014] Furthermore, the second driving motor is a stepping motor.

[0015] Furthermore, the rotating seat body is a square plate body; both side edges of the rotating seat body are sunken to provide a step, and the linear slide rail is arranged on the step; a groove is provided in the middle of the rotating seat body along the length direction of the screw body, the bearing support is arranged in the groove, and the width of the groove is equal to the length of the bearing support.

[0016] Furthermore, the clamping body includes a clamping main board and a connecting plate, and the connecting plate is connected to the screw rod moving mechanism; the clamping main board is connected to the connecting plate, and the clamping main board and the connecting plate are arranged perpendicular to each other, and a reinforcing plate is arranged between the clamping main board and the connecting plate.

[0017] By adopting the technical solution of the utility model, at least the following beneficial effects are achieved:

[0018] 1. The high-torque pipe clamp positioner is designed to include a rotary drive mechanism, so that during specific work, the rotary drive mechanism can drive the rotating seat to drive the screw moving mechanism, the moving drive mechanism and the clamping body to perform 360° rotation and displacement, so that the pipe clamp positioner can adapt to the clamping needs of various angles and is more convenient to use; at the same time, the screw moving mechanism is used to drive the two clamping bodies to move to realize the clamping function. Through the deceleration effect of the screw moving mechanism, the two clamping bodies arranged in opposite directions can be subjected to a large thrust, which can effectively increase the clamping force of the pipe clamp positioner, so that the pipe can be clamped more reliably.

[0019] 2. By arranging rubber contact plates on the opposite sides of the two clamping bodies, the rubber contact plates can be used to contact the pipe during the clamping process. Since the rubber contact plates have a certain elasticity, they can not only better clamp the pipe and ensure that the pipe will not fall off during the clamping process, but also prevent damage to the surface of the pipe.

[0020] 3. By designing that when the screw moving mechanism drives the two clamping bodies to move away from each other to the limit position, the distance between the two rubber contact plates is greater than 200mm; and when the screw moving mechanism drives the two clamping bodies to move closer to each other to the limit position, the distance between the two rubber contact plates is less than 50mm; in the actual use process, it can well adapt to the clamping operation of 50-200mm pipes, so as to better meet the use needs of various different occasions.

In addition, the terms "first", "second", etc., etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0041] See also Figures 1 to 8As shown, a preferred embodiment of a high torque pipe clamping positioner 100 of the utility model, the pipe clamping positioner 100 comprises a rotating seat 1, a rotating drive mechanism 2, a screw moving mechanism 3, a moving drive mechanism 4 and a clamping body 5;

[0042] The rotating seat body 1 is connected to the output end of the rotating drive mechanism 2; the screw moving mechanism 3 is arranged on the side of the rotating seat body 1 facing away from the rotating drive mechanism 2, and the screw moving mechanism 3 is threadedly connected with two clamping bodies 5, and the two clamping bodies 5 are arranged opposite to each other, and the mobile drive mechanism 4 is connected to the screw moving mechanism 3; when working, the mobile drive mechanism 4 drives the screw moving mechanism 3 to drive the two clamping bodies 5 to approach or move away from each other, so as to achieve the clamping or release of the pipeline 200 (such as the square pipe used in the construction of nuclear power plants); the rotating seat body 1 is driven by the rotating drive mechanism 2 to drive the screw moving mechanism 3, the mobile drive mechanism 4 and the clamping body 5 to rotate and displace. Specifically, the rotating seat body 1 can be driven by the rotating drive mechanism 2 to drive the screw moving mechanism 3, the mobile drive mechanism 4 and the clamping body 5 to rotate and displace 360°.

[0043] The utility model includes a rotating drive mechanism 2 through the design of the pipe clamping positioner 100, so that in specific operation, the rotating drive mechanism 2 can drive the rotating seat body 1 to drive the screw moving mechanism 3, the moving drive mechanism 4 and the clamping body 5 to rotate and displace 360°, so that the pipe clamping positioner 100 can adapt to the clamping requirements of various angles and is more convenient to use; at the same time, the screw moving mechanism 3 is used to drive the two clamping bodies 5 to move to realize the clamping function. Through the deceleration effect of the screw moving mechanism 3, the two clamping bodies 5 arranged in opposite directions can be subjected to a large thrust, which can effectively increase the clamping force of the pipe clamping positioner 100, so that the pipe 200 can be clamped more reliably.

[0044] In some embodiments of the utility model, the two clamping bodies 5 are both provided with a rubber contact plate 6 on the opposite side. The utility model provides the rubber contact plate 6 on the opposite side of the two clamping bodies 5, so that the rubber contact plate 6 can be used to contact the pipe 200 during the clamping process. Since the rubber contact plate 6 has a certain elasticity, it can not only better clamp the pipe 200 and ensure that the pipe 200 will not fall off during the clamping process, but also prevent damage to the surface of the pipe rubber contact plate 6.

[0045] As a specific implementation of the utility model, the two rubber contact plates 6 are formed with protrusions or convex strips (not shown) on the facing sides, which can increase the friction between the pipe and the rubber contact plate 6 and ensure that the pipe clamping positioner 100 can better clamp the pipe.

[0046] In some embodiments of the utility model, when the screw moving mechanism 3 drives the two clamping bodies 5 to move away from each other to the extreme position (that is, when the two clamping bodies 5 move away from each other to the farthest position), the distance between the two rubber contact plates 6 is greater than 200 mm; when the screw moving mechanism 3 drives the two clamping bodies 5 to move closer to each other to the extreme position (that is, when the two clamping bodies 5 move closer to each other to the closest position), the distance between the two rubber contact plates 6 is less than 50 mm.

[0047] The utility model is designed such that when the screw moving mechanism 3 drives the two clamping bodies 5 to move away from each other to the limit position, the distance between the two rubber contact plates 6 is greater than 200 mm; and when the screw moving mechanism 3 drives the two clamping bodies 5 to move closer to each other to the limit position, the distance between the two rubber contact plates 6 is less than 50 mm. In actual use, the utility model can well adapt to the clamping operation of the pipe of 50-200 mm, so as to better meet the use requirements of various different occasions.

[0048] In some embodiments of the present invention, please refer to Figure 6 As shown, the rotary drive mechanism 2 includes a first drive motor 21, a reducer 22 and a motor mounting seat 23; the first drive motor 21 is mounted on the motor mounting seat 23, so as to support the first drive motor 21 by using the motor mounting seat 23; the output end of the first drive motor 21 is connected to the reducer 22, and the output end of the reducer 22 is connected to the middle part of the rotating seat body 1. When working, the power is output through the first drive motor 21, and the rotating seat body 1 is driven to rotate 360° after being decelerated by the reducer 22 to realize the displacement function. When the utility model is used in practice, the motor mounting seat 23 can be fixed on a transport device (such as a work vehicle, etc.), so as to realize the installation of the entire pipe clamping positioner 100 on a transport device (such as a work vehicle, etc.).

[0049] As a specific implementation of the utility model, the reducer 22 adopts a harmonic reducer. A harmonic reducer is an existing reduction device, mainly composed of three basic components: a fixed internal gear rigid wheel, a flexible wheel and a wave generator that causes the flexible wheel to undergo radial deformation; the use of a harmonic reducer has the following advantages: small load per unit area, higher carrying capacity than other transmission forms; small size, light weight; high transmission efficiency, long life; stable transmission, no impact, no noise, and high motion accuracy.

During operation, the screw body 31 is driven to rotate by the mobile driving mechanism 4. Since the two screw sliders 34 are both threadedly connected to the screw body 31, and the moving directions of the two screw sliders 34 on the screw body 31 are opposite, the screw body 31 can drive the two screw sliders 34 to approach or move away from each other during rotation, thereby bringing the two clamping bodies 5 closer to each other to clamp the pipe or moving away from each other to release the pipe. At the same time, linear slide rails 32 and linear sliders 33 are provided on both sides of the screw body 31, which can play a good guiding role in the movement of the clamping body 5, ensuring that the two clamping bodies 5 can smoothly approach or move away from each other.

[0052] In some embodiments of the utility model, the mobile drive mechanism 4 includes a second drive motor 41 and a synchronous belt 42; the second drive motor 41 is installed on the rotating seat body 1, and the output end of the second drive motor 41 is connected to one end of the screw body 31 through the synchronous belt 42. When working, the second drive motor 41 outputs power to drive the synchronous belt 42 for transmission. During the transmission process, the synchronous belt 42 can drive the screw body 31 to rotate, and the forward and reverse rotation of the second drive motor 41 can be used to drive the two clamping bodies 5 to move closer to or away from each other.

[0053] As a specific embodiment of the present invention, the second drive motor 41 adopts a stepper motor. A stepper motor is an open-loop control element that converts an electrical pulse signal into an angular displacement or a linear displacement; its working principle is to use an electronic circuit to convert direct current into a multi-phase timing control current for time-sharing power supply, and use this current to power the stepper motor to make the stepper motor work; by using a stepper motor, the control accuracy can be guaranteed.

[0054] In some embodiments of the present invention, please refer to Figure 8As shown, the rotating seat body 1 is a square plate body; both side edges of the rotating seat body 1 are sunken to provide a step 11, and the linear slide rail 32 is arranged on the step 11; a groove 12 is provided in the middle of the rotating seat body 1 along the length direction of the screw body 31, and the bearing support 35 is arranged in the groove 12, and the width of the groove 12 is equal to the length of the bearing support 35, so that after the bearing support 35 is arranged in the groove 12, the groove 12 can be used to play a good limiting role on the bearing support 35.

[0055] The utility model is designed to have steps 11 on both side edges of the rotating seat body 1, a groove 12 in the middle of the rotating seat body 1, and the linear guide rail 32 is installed on the step 11, and the bearing support 35 is arranged in the groove 12. This helps to make the structure of the entire pipe clamping positioner 100 more compact, and at the same time can ensure the stability of the linear guide rail 32 and the bearing support 35 after installation.

[0056] As a specific embodiment of the present utility model, the second drive motor 41 is arranged on the side of the rotating seat body 1 facing away from the screw moving mechanism 3, and an avoidance gap 13 is opened on the rotating seat body 1 at the position corresponding to the output end of the second drive motor 41, and the synchronous belt 42 passes through the avoidance gap 13 to connect the output end of the second drive motor 41 with one end of the screw body 31.

[0057] In some embodiments of the present invention, please refer to Figure 7 As shown, the clamping body 5 includes a clamping main board 51 and a connecting plate 52, and the connecting plate 52 is connected to the screw moving mechanism 3, specifically, the connecting plate 52 is locked and connected with the screw slider 34 of the screw moving mechanism 3; the clamping main board 51 is connected to the connecting plate 52, and the clamping main board 51 and the connecting plate 52 are arranged perpendicular to each other, and a reinforcing plate 53 is arranged between the clamping main board 51 and the connecting plate 52 to enhance the connection strength between the clamping main board 51 and the connecting plate 52.
