Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline construction technology, specifically to a splicing device for water conservancy projects. Background Technology

[0002] Water pipelines, as key facilities for transporting water resources, play an indispensable role in irrigation, water supply, and drainage, and are an important engineering support for water resource management and efficient utilization. With the continuous expansion of water conservancy project construction, the efficiency and quality of pipeline splicing directly affect project progress and subsequent performance.

[0003] In the prior art, such as the splicing device for water conservancy pipelines disclosed in patent announcement number CN222328077U, it belongs to the field of water conservancy pipeline splicing technology. This device includes a base plate and a support platform located above the base plate, the support platform supporting the water conservancy pipeline; the adjustment structure on the base plate includes a groove formed in the base plate, the base plate being slidably connected to a first slider through the groove, and rotatably connected to a first threaded rod, the outer side of the first threaded rod being threadedly connected to the inner wall of the first slider. By rotating the first threaded rod, the second threaded rod, and the third threaded rod, the support platform can move back and forth, left and right, and up and down to a small extent, thereby driving the water conservancy pipeline placed on the support platform to complete the corresponding adjustment, achieving the purpose of slightly aligning the connection ends of the water conservancy pipeline, effectively saving manpower and ensuring the speed of splicing operations.

[0004] However, in practical applications, it was found that the aforementioned device lacked a rotation adjustment mechanism. Since precise alignment of the flange holes is crucial for ensuring a stable connection during pipe splicing, the absence of a rotation adjustment mechanism makes it difficult for operators to accurately control the circumferential angle when adjusting the flange hole position. This increases the difficulty of splicing, reduces construction efficiency, and fails to fully meet the needs of rapid and precise splicing of water conservancy pipelines under complex working conditions. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a splicing device for pipelines in water conservancy projects, which has the advantage of rotational adjustment and solves the problems of existing devices being unable to achieve pipeline rotational adjustment and being difficult to accurately align flange holes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a splicing device for pipelines in water conservancy projects, comprising a splicing device body and a placement platform. The placement platform is fixedly installed on the top of the splicing device body. Mounting frames are provided on the front and rear sides of the top of the placement platform. Rotation adjustment components are movably connected to the left and right sides inside the mounting frames via bearings. The rotation adjustment components include adjustment rods, which are movably connected to the left and right sides inside the mounting frames via bearings. A rotating roller is fixedly connected to the inner end of the adjustment rods. A specification adjustment component is fixedly installed at the bottom of the mounting frames.

[0007] As a preferred embodiment of this utility model, the specification adjustment component includes an adjustment block, which is fixedly installed at the bottom of the mounting frame, and a bidirectional screw is threadedly connected to the top of the adjustment block.

[0008] In a preferred embodiment of this invention, the front and rear sides of the bidirectional screw surface are movably connected to support blocks via bearings, and the bottom of the support blocks is fixedly connected to the top of the placement platform.

[0009] In a preferred embodiment of this invention, the bottom of the adjusting block is slidably connected to a limiting rod through a through hole, and the two ends of the limiting rod are fixedly connected to the inner side of the support block.

[0010] As a preferred embodiment of this utility model, a motor mounting plate is fixedly mounted on the left side of the front mounting bracket, and a drive motor is fixedly mounted on the top of the motor mounting plate. The output end of the drive motor is fixedly connected to the left side of the front left adjustment rod.

[0011] As a preferred embodiment of this invention, a control panel is fixedly installed on the left side of the placement platform, and the control panel is electrically connected to the drive motor via wires.

[0012] As a preferred embodiment of this utility model, a battery bracket is fixed on the left side of the splicing device body, and a mobile power supply is fixedly installed on the top of the motor mounting bracket. The mobile power supply is electrically connected to the control panel and the drive motor through wires.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of a rotary adjustment component, uses the cooperation of an adjustment rod and a rotating roller. During adjustment, the water pipe is placed on the rotating roller, the drive motor is started, and the drive motor drives the adjustment rod on the front left side to rotate, thereby causing the rotating roller to rotate. Utilizing the friction between the rotating roller and the pipe surface, the pipe is rotated, and the position of the pipe flange hole is precisely adjusted to achieve accurate alignment with the flange hole of another pipe, completing the pipe splicing operation. This significantly improves the accuracy and efficiency of pipe splicing, and solves the problem that existing devices cannot achieve pipe rotation adjustment and are difficult to accurately align flange holes, thus achieving the effect of rotary adjustment.

[0015] 2. By setting up a specification adjustment component, the bidirectional screw and the adjustment block are threaded together to realize the adjustability of the mounting bracket spacing, so that the device can adapt to the splicing requirements of water conservancy pipelines with different pipe diameters, and significantly improve the versatility and applicability of the device.

[0016] 3. By setting a support block, which is connected to the bidirectional screw through a bearing, this utility model allows the bidirectional screw to rotate freely and can withstand the axial force generated during the adjustment process, transmitting the force to the placement platform. This provides a stable support structure for the bidirectional screw, ensuring that the bidirectional screw remains stable during rotation and avoiding shaking or deviation, thus guaranteeing the accuracy and reliability of the adjustment process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a splicing device for pipelines in water conservancy projects, including a splicing device body 1 and a placement platform 2. The placement platform 2 is fixedly installed on the top of the splicing device body 1. Mounting frames 3 are provided on the front and rear sides of the top of the placement platform 2. Rotation adjustment components 4 are movably connected to the left and right sides inside the mounting frames 3 through bearings. The rotation adjustment components 4 include adjustment rods 41, which are movably connected to the left and right sides inside the mounting frames 3 through bearings. A rotating roller 42 is fixedly connected to the inner end of the adjustment rods 41. A specification adjustment component 5 is fixedly installed at the bottom of the mounting frames 3.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The specification adjustment component 5 includes an adjustment block 51, which is fixedly installed at the bottom of the mounting bracket 3. A bidirectional screw 52 is threadedly connected to the top of the adjustment block 51.

[0024] As a technical optimization of this utility model, by setting up a specification adjustment component 5, the threaded engagement of the bidirectional screw 52 and the adjustment block 51 realizes the adjustability of the spacing of the mounting frame 3, enabling the device to adapt to the splicing requirements of water conservancy pipelines with different diameters, and significantly improving the versatility and applicability of the device.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The front and rear sides of the surface of the bidirectional screw 52 are movably connected to the support block 6 via bearings, and the bottom of the support block 6 is fixedly connected to the top of the placement platform 2.

[0026] As a technical optimization of this utility model, by setting a support block 6, which is connected to the bidirectional screw 52 through a bearing, the bidirectional screw 52 is allowed to rotate freely, and can also withstand the axial force generated during the adjustment process, transmitting the force to the placement platform 2. This provides a stable support structure for the bidirectional screw 52, ​​ensuring that the bidirectional screw 52 remains stable during rotation, avoiding shaking or deviation, and ensuring the accuracy and reliability of the adjustment process.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The bottom of the adjusting block 51 is slidably connected to the limiting rod 7 through a through hole, and the two ends of the limiting rod 7 are fixedly connected to the inner side of the support block 6.

[0028] As a technical optimization of this utility model, by setting a limiting rod 7, the limiting rod 7 and the adjusting block 51 slide together to guide and limit the movement of the adjusting block 51, preventing the adjusting block 51 from rotating or deviating during the movement, and ensuring that the movement trajectory of the mounting frame 3 is accurate and controllable.

[0029] refer to Figure 1 , Figure 2 and Figure 3 A motor mounting plate 8 is fixedly installed on the left side of the front mounting bracket 3, and a drive motor 9 is fixedly installed on the top of the motor mounting plate 8. The output end of the drive motor 9 is fixedly connected to the left side of the front left adjustment rod 41.

[0030] As a technical optimization of this utility model, by setting a motor mounting plate 8 and a drive motor 9, the drive motor 9 provides power to the rotation adjustment component 4, realizing the automatic rotation adjustment of the pipeline, reducing the labor intensity of operators, and improving the efficiency and accuracy of pipeline flange hole alignment.

[0031] refer to Figure 1 , Figure 2 and Figure 3 A control panel 10 is fixedly installed on the left side of the placement platform 2. The control panel 10 is electrically connected to the drive motor 9 via wires.

[0032] As a technical optimization of this utility model, by setting up a control panel 10, which serves as the operation center of the device, it is convenient for operators to control the drive motor 9 and to precisely adjust the rotation angle of the pipeline according to actual needs, thereby improving the convenience and accuracy of operation.

[0033] refer to Figure 1 , Figure 2 and Figure 3 A battery bracket 11 is fixed on the left side of the splicing device body 1, and a mobile power supply 12 is fixedly installed on the top of the motor mounting bracket 3. The mobile power supply 12 is electrically connected to the control panel 10 and the drive motor 9 through wires.

[0034] As a technical optimization of this utility model, the battery holder 11 and the mobile power supply 12 provide an independent power supply for the device, eliminating the dependence on external power sources and enabling the device to work normally in environments without power, such as in the field, which significantly expands the application scenarios and flexibility of the device.

[0035] The working principle and usage process of this utility model are as follows: First, the water pipe to be spliced ​​is placed on the placement platform 2. Depending on the pipe diameter, when the bidirectional screw 52 is rotated, because the two sections of the thread on the surface of the bidirectional screw 52 rotate in opposite directions, the adjusting blocks 51 on both sides will move synchronously inward or outward along the thread direction, driving the mounting frame 3 to adjust the spacing to match the current pipe diameter. During the adjustment process, the limiting rod 7 slides with the through hole at the bottom of the adjusting block 51, guiding and limiting the movement of the adjusting block 51, preventing it from rotating or shifting, and ensuring the smooth movement of the mounting frame 3. After the pipe diameter is matched, the drive motor 9 is started. The output end of the drive motor 9 drives the adjusting rod 41 to rotate, and the rotating roller 42 fixed at the inner end of the adjusting rod 41 rotates accordingly. The rotating roller 42 contacts the pipe surface. The friction force drives the pipe to rotate, thereby adjusting the angle of the pipe flange holes. The operator can send commands to the drive motor 9 through the control panel 10 to control the motor's start, stop, speed and direction, thereby precisely adjusting the pipe rotation angle and ensuring accurate alignment of the flange holes between the pipes. Once the flange holes are aligned, the pipe splicing operation can be carried out. Throughout the process, the mobile power supply 12 supplies power to the control panel 10 and the drive motor 9 through wires, enabling the device to work normally in an environment without external power, ensuring the smooth progress of the water conservancy pipeline splicing operation. (It should be noted that the specific working principle of the splicing device body 1 can be found in the splicing device for water conservancy pipelines disclosed in patent authorization announcement number CN222328077U, which belongs to the existing known technology and will not be elaborated further here.)

[0036] In summary, this pipe splicing device for water conservancy projects, through the rotation adjustment component 4 and the cooperation of the adjustment rod 41 and the rotating roller 42, allows the water conservancy pipe to be placed on the rotating roller 42 during adjustment. The drive motor 9 is then started, causing the adjustment rod 41 on the front left side to rotate, which in turn rotates the rotating roller 42. Utilizing the friction between the rotating roller 42 and the pipe surface, the pipe rotates, precisely adjusting the position of the pipe flange hole to achieve accurate alignment with the flange hole of another pipe, thus completing the pipe splicing operation. This significantly improves the accuracy and efficiency of pipe splicing and solves the problems of existing devices being unable to achieve pipe rotation adjustment and accurately aligning flange holes.
