[0018] 1. For the pipeline connection auxiliary device for water conservancy construction, the moving mechanism drives the rotating shaft through the first servo motor, and then drives the gear to rotate. Since the gear meshes with the rack on the inner wall of the fixed frame, when the gear rotates, under the action of the rack, components such as the fixed frame and the sliding sleeve and the moving plate connected thereto can slide precisely left and right along the fixed frame.

The first articulated frame is connected to the second articulated frame through an articulated rod, and then drives the lifting plate and the first clamping block to move up and down. When the first clamping block cooperates with the second clamping block fixed at the bottom of the inner wall of the rectangular frame, it can strongly and stably clamp the pipeline. The rubber strips provided on the arc surfaces of the first clamping block and the second clamping block increase the friction with the pipeline and play a buffering role at the same time. It can not only prevent the pipeline from being damaged during the clamping process, but also ensure that the pipeline will not be displaced due to external forces during the pipeline connection process, ensuring the smooth progress of the connection operation.

[0029] The present invention provides the following technical solutions:

[0030] Embodiment 1

[0031] Please refer to Figures 1-4 , the present invention provides a technical solution: a pipeline connection auxiliary device for water conservancy construction, including a base 1, a fixed seat 2 is fixedly connected to the left side of the top of the base 1, a moving mechanism 3 is arranged on the top of the base 1, and clamping mechanisms 4 are arranged on the top of the moving mechanism 3 and the top of the fixed seat 2;

A fixing frame 32 is fixedly connected to the tops of the two fixing plates 31. A sliding sleeve 33 is slidably connected to the left and right surfaces of the fixing frame 32.

[0033] A hole is formed in the front of the fixing bracket 34 for the first servo motor 37, and the output shaft surface of the first servo motor 37 penetrates through and is rotatably connected in the hole.

[0034] The output end of the first servo motor 37 is fixedly connected to the front end of the rotating shaft 35, and the gear 36 meshes with the rack bar 38.

[0035] The left and right sides of the inner wall of the sliding bracket 311 are slidably connected to the top of the rack bar 38. The sliding bracket 311 presses against the meshing part of the gear 36 and the rack bar 38, so that the gear 36 and the rack bar 38 can mesh better.

[0036] Embodiment Two

[0037] Please refer to Figure 5 and, on the basis of Embodiment One, a clamping mechanism 4 is further obtained.

[0038] The clamping mechanism 4 includes a rectangular frame 41. The rectangular frame 41 is fixedly connected to the tops of the moving plate 39 and the fixed seat 2. Rotating shafts of a bidirectional lead screw 42 are rotatably connected to the front and rear sides near the top of the inner wall of the rectangular frame 41. A second servo motor 43 is fixedly connected to the front near the top of the rectangular frame 41. First articulated frames 44 are symmetrically threadedly connected to the front and rear surfaces of the bidirectional lead screw 42. Limiting rods 45 are fixedly connected to the front and rear sides near the top of the inner wall of the rectangular frame 41. An articulated rod 46 is articulated inside the first articulated frame 44. The other end of the articulated rod 46 is articulated to a second articulated frame 47. A lifting plate 48 is fixedly connected to the bottom of the second articulated frame 47. A first clamping block 49 is fixedly connected to the bottom of the lifting plate 48. A second clamping block 411 is fixedly connected to the bottom of the inner wall of the rectangular frame 41.

[0039] A hole matching the output shaft of the second servo motor 43 is formed in the front near the top of the rectangular frame 41, and the output shaft surface of the second servo motor 43 passes through and is rotatably connected in the hole.

[0040] The output end of the second servo motor 43 is fixedly connected to the front end of the bidirectional lead screw 42, and the limiting rod 45 is located above the bidirectional lead screw 42.

[0041] A hole matching the limiting rod 45 is formed near the top on the front surface of the first hinge frame 44, and the first hinge frame 44 is slidably connected to the surface of the limiting rod 45 through the hole. The limiting rod 45 limits the two first hinge frames 44, so that the first hinge frames 44 move towards each other as the bidirectional lead screw 42 rotates.

[0042] Rubber strips are arranged on the arc surfaces of the first clamping block 49 and the second clamping block 411, which can enable the first clamping block 49 and the second clamping block 411 to better clamp the pipeline. The two clamping mechanisms 4 are in the same horizontal position.

[0043] During the actual operation process, when this device is in use and it is necessary to clamp a pipeline, the second servo motor 43 is started. The output end of the second servo motor 43 drives the front end of the bidirectional lead screw 42 to rotate. The first hinge brackets 44 symmetrically thread-connected to the front and rear surfaces of the bidirectional lead screw 42 move towards or away from each other under the action of screw drive as the bidirectional lead screw 42 rotates. Since a hole matching the limit rod 45 is provided near the top on the front surface of the first hinge bracket 44 and the first hinge bracket 44 is slidably connected to the surface of the limit rod 45 through this hole in the front and rear directions, the limit rod 45 plays a limiting role on the first hinge bracket 44, enabling it to move only in the front and rear directions along the direction of the limit rod 45, ensuring the stability and accuracy of the movement of the first hinge bracket 44. The first hinge bracket 44 is connected to the second hinge bracket 47 through a hinge rod 46. When the first hinge bracket 44 moves towards or away from each other, the hinge rod 46 will drive the second hinge bracket 47 to move up and down. The lifting plate 48 fixedly connected to the bottom of the second hinge bracket 47 will also move up and down accordingly. The distance between the first clamping block 49 fixedly connected to the bottom of the lifting plate 48 and the second clamping block 411 fixedly connected to the bottom inner wall of the rectangular frame 41 will change. The construction personnel can precisely adjust the distance between the first clamping block 49 and the second clamping block 411 by controlling the rotation direction and number of turns of the second servo motor 43 to adapt to water conservancy pipelines with different pipe diameters. After the distance between the first clamping block 49 and the second clamping block 411 is adjusted to the appropriate position, the pipeline is placed on the second clamping block 411, and the second servo motor 43 is started again to lower the first clamping block 49 to cooperate with the second clamping block 411 to clamp the pipeline. The rubber strips provided on the arc surfaces of the first clamping block 49 and the second clamping block 411 increase the friction with the pipeline and play a buffering role at the same time. It can not only prevent the pipeline from being damaged during the clamping process but also ensure the firmness of the clamping. The two clamping mechanisms 4 are respectively located on the moving plate 39 and the top of the fixed seat 2 and are at the same horizontal position, capable of stably clamping two pipelines simultaneously, facilitating the pipeline connection operation for the construction personnel. After the first servo motor 37 is started, its output end drives the front end of the rotating shaft 35 fixedly connected thereto to rotate. The gear 36 fixedly connected to the middle of the surface of the rotating shaft 35 rotates synchronously with the rotating shaft 35. Since the gear 36 meshes with the racks 38 fixedly connected to the left and right sides of the inner wall of the fixed frame 32, the rotation of the gear 36 is converted into a linear motion along the direction of the rack 38. This gear-rack 36-38 transmission method can accurately convert the rotational motion of the motor into the horizontal linear motion of the fixed frame 34 and related components. The fixed frame 34 is fixedly connected to the sliding sleeve 33. When the fixed frame 34 moves under the action of the gear 36 and the rack 38, the sliding sleeve 33 will also slide left and right on the surface of the fixed frame 32. The moving plate 39 fixedly connected to the top of the sliding sleeve 33 will move together with the sliding sleeve 33, thereby realizing the position adjustment of the clamping mechanism 4 placed on the top of the moving plate 39. In this process, the sliding frame 311 plays an important auxiliary role.The left and right sides of the inner wall of the sliding carriage 311 are slidably connected to the top of the rack 38, pressing against the meshing portion of the gear 36 and the rack 38, ensuring that the gear 36 and the rack 38 always maintain a good meshing state, avoiding jamming or disengagement during the movement, and ensuring the smoothness and accuracy of the movement process. The construction personnel can precisely control the movement direction and speed of the moving plate 39 and the clamping mechanism 4 by controlling the forward and reverse rotation and the speed of the first servo motor 37, and accurately move the pipeline to the position where it needs to be connected.

[0044] The present invention also discloses a pipeline connection construction method, which is suitable for operating the pipeline connection auxiliary device for water conservancy construction described in any one of the above. The specific method is as follows: When it is necessary to clamp the pipeline, the second servo motor 43 is started. The output end of the second servo motor 43 drives the front end of the bidirectional lead screw 42 to rotate. The first hinge brackets 44 are symmetrically and threadedly connected to the front and rear surfaces of the bidirectional lead screw 42. Under the action of the threaded drive, they move towards or away from each other as the bidirectional lead screw 42 rotates. Since a hole matching the limit rod 45 is opened near the top of the front surface of the first hinge bracket 44 and the first hinge bracket 44 is slidably connected to the surface of the limit rod 45 through this hole, the limit rod 45 plays a limiting role on the first hinge bracket 44, enabling it to move only back and forth along the direction of the limit rod 45, ensuring the stability and accuracy of the movement of the first hinge bracket 44. The first hinge bracket 44 is connected to the second hinge bracket 47 through a hinge rod 46. When the first hinge bracket 44 moves towards or away from each other, the hinge rod 46 will drive the second hinge bracket 47 to move up and down. The lifting plate 48 fixedly connected to the bottom of the second hinge bracket 47 will also move up and down accordingly. The distance between the first clamping block 49 fixedly connected to the bottom of the lifting plate 48 and the second clamping block 411 fixedly connected to the bottom inner wall of the rectangular frame 41 will change. The construction worker can precisely adjust the distance between the first clamping block 49 and the second clamping block 411 by controlling the rotation direction and number of turns of the second servo motor 43 to adapt to water conservancy pipelines with different diameters. After the distance between the first clamping block 49 and the second clamping block 411 is adjusted to the appropriate position, the pipeline is placed on the second clamping block 411, and the second servo motor 43 is started again to lower the first clamping block 49 to cooperate with the second clamping block 411 to clamp the pipeline. The rubber strips provided on the arc surfaces of the first clamping block 49 and the second clamping block 411 increase the friction with the pipeline and play a buffering role at the same time. It can not only prevent the pipeline from being damaged during the clamping process but also ensure the firmness of the clamping. The two clamping mechanisms 4 are respectively located on the top of the moving plate 39 and the fixed seat 2 and are at the same horizontal position, capable of stably clamping two pipelines simultaneously, facilitating the pipeline connection operation for the construction worker. After the first servo motor 37 is started, its output end drives the front end of the rotating shaft 35 fixedly connected thereto to rotate. The gear 36 fixedly connected to the middle of the surface of the rotating shaft 35 rotates synchronously with the rotating shaft 35. Since the gear 36 meshes with the racks 38 fixedly connected to the left and right sides of the inner wall of the fixed frame 32, the rotation of the gear 36 is converted into a linear motion along the direction of the rack 38. This gear-rack 36-38 transmission method can accurately convert the rotational motion of the motor into the horizontal linear motion of the fixed frame 34 and related components. The fixed frame 34 is fixedly connected to the sliding sleeve 33. When the fixed frame 34 moves under the action of the gear 36 and the rack 38, the sliding sleeve 33 will also slide left and right on the surface of the fixed frame 32. The moving plate 39 fixedly connected to the top of the sliding sleeve 33 will move together with the sliding sleeve 33, thereby realizing the position adjustment of the clamping mechanism 4 placed on the top of the moving plate 39. In this process, the sliding frame 311 plays an important auxiliary role.The inner walls on the left and right of the sliding frame 311 are slidably connected to the top of the rack 38, pressing against the meshing part of the gear 36 and the rack 38, ensuring that the gear 36 and the rack 38 always maintain a good meshing state, avoiding jamming or disengagement during movement, and ensuring the smoothness and accuracy of the movement process. Construction workers can precisely control the moving direction and speed of the moving plate 39 and the clamping mechanism 4 by controlling the forward and reverse rotation and speed of the first servo motor 37, and accurately move the pipeline to the position where connection is required.
