Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy construction tools, and in particular relates to a water conservancy pipeline reinforcement device. Background Technology

[0002] Currently, numerous pipelines need to be laid in water conservancy projects. These pipelines need to be reinforced with reinforcement devices to prevent them from shaking arbitrarily during use and affecting the stability of the connection.

[0003] However, currently, when reinforcing water pipelines, support brackets are often used at the bottom of the pipeline for support. To ensure sufficient contact between the support brackets and the outer walls of pipes of different diameters, providing adequate support, the support brackets contain adjustable clamping plates. However, operators cannot adjust the clamping plates simultaneously, resulting in numerous adjustment steps, which is time-consuming, labor-intensive, and reduces the efficiency of the pipeline reinforcement operation. Therefore, we propose a water pipeline reinforcement device. Summary of the Invention

[0004] In view of the fact that the clamping plates in the above-mentioned prior art cannot be adjusted synchronously, which is cumbersome to operate and affects work efficiency, this utility model provides a water conservancy pipeline reinforcement device. The technical solution is: including a hollow frame, a fixed frame is set at the top of the hollow frame, and transmission frames are set at both ends of the hollow frame. The transmission frames are connected to the clamping plates through push rods.

[0005] In a preferred embodiment, the inner wall of the hollow frame is provided with a transmission chain ring, and both ends of the transmission chain ring are provided with a driving sprocket and a driven sprocket, both of which mesh with the transmission chain ring.

[0006] In a preferred embodiment, the clamping plate is an arc-shaped sheet structure that fits the water pipe to ensure its stability when clamping the pipe.

[0007] In a preferred embodiment, a rotating rod is provided at the bottom of the driving sprocket, the rotating rod passes through the bottom of the hollow frame, and a transmission rod is provided at the top of both the driving sprocket and the driven sprocket. The transmission rod passes through the top of the hollow frame and is inserted into the transmission frame through a bearing.

[0008] In a preferred embodiment, the top of each transmission rod is fixedly provided with a bidirectional lead screw, and both the upper and lower ends of the bidirectional lead screw are provided with threaded lifting sleeves. The lifting sleeve is hinged to one end of the push rod, and the other end of the push rod is hinged to the middle section of the clamping plate. The push rod passes through the limiting groove on the fixed frame.

[0009] In a preferred embodiment, a guide groove is provided on the middle section of the fixed frame, and a guide rod is provided in the guide groove. The guide rod is fixedly connected to the bottom of the clamping plate, and the guide rod slides in conjunction with the guide groove.

[0010] In a preferred embodiment, the side wall of the rotating rod is fixedly connected to the connecting frame, the connecting frame has an opening at its center, and the connecting frame is threadedly engaged with the adjusting bolt.

[0011] In a preferred embodiment, when the adjusting bolt is tightened, the adjusting bolt presses the abutment plate against the bottom of the hollow frame; when the adjusting bolt is loosened, the abutment plate does not contact the adjusting bolt or the hollow frame.

[0012] In a preferred embodiment, the bottom of the hollow frame is fixedly connected to the transmission end of the electric actuator, and the electric actuator is fixedly mounted on the fixed base.

[0013] In a preferred embodiment, there are at least two sets of electric actuators, symmetrically arranged along the geometric center of the hollow frame.

[0014] The beneficial effects of this utility model are:

[0015] (1) The device connects the bidirectional lead screw and the follower sprocket through the transmission rod. Under the meshing transmission action of the transmission chain ring, combined with the meshing transmission action of the transmission chain ring on the transmission sprocket and the follower sprocket, the operator can drive the two sets of transmission rods to rotate synchronously and in the same direction after driving the rotating rod. This can drive the bidirectional lead screw located inside the hollow frame to rotate synchronously and in the same direction. Combined with the transmission action of the bidirectional lead screw on the lifting sleeve, the two sets of lifting sleeves can move synchronously vertically towards each other or relative to each other. Under the transmission conversion action of the push rod, the vertical movement force of the lifting sleeve is converted into a horizontal pushing force on the clamping plate. This allows the two sets of clamping plates to move synchronously towards each other or relative to each other horizontally, so that they can be fitted and reinforced on the outside of the construction pipeline. This reduces the number of operation steps required for the operator to adjust it step by step and improves the efficiency of water conservancy pipeline reinforcement construction.

[0016] (2) By sliding the guide rod into the guide groove, and combined with the guiding sliding action of the guide groove on the guide rod, the clamping plate can only move horizontally inside the fixed frame when it is pushed, without vertical shaking, which further improves the bonding and reinforcement stability of the clamping arc plate to the water conservancy pipeline.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figure 1-3 The water conservancy pipeline reinforcement device shown includes a hollow frame 6, a fixing frame 3 is provided on the top of the hollow frame 6, and a transmission frame 5 is provided at both ends of the hollow frame 6. The transmission frame 5 is connected to the clamping plate 4 through a push rod 14.

[0024] Furthermore, the inner wall of the hollow frame 6 is provided with a transmission chain ring 9, and the two ends of the transmission chain ring 9 are provided with a driving sprocket 8 and a driven sprocket 11, both of which are engaged with the transmission chain ring 9.

[0025] Furthermore, the clamping plate 4 is an arc-shaped sheet structure that fits the water pipe, making it stable when clamping the pipe.

[0026] Furthermore, the bottom of the drive sprocket 8 is provided with a rotating rod 7, which passes through the bottom of the hollow frame 6. The top of both the drive sprocket 8 and the driven sprocket 11 is provided with a transmission rod 10, which passes through the top of the hollow frame 6 and is inserted into the transmission frame 5 through a bearing.

[0027] Furthermore, the top of each transmission rod 10 is fixedly provided with a bidirectional lead screw 12, and both the upper and lower ends of the bidirectional lead screw 12 are provided with threaded lifting sleeves 13. The lifting sleeve 13 is hinged to one end of the push rod 14, and the other end of the push rod 14 is hinged to the middle section of the clamping plate 4. The push rod 14 passes through the limiting groove 21 on the fixed frame 3.

[0028] Furthermore, a guide groove 16 is provided on the middle section of the fixed frame 3, and a guide rod 15 is provided in the guide groove 16. The guide rod 15 is fixedly connected to the bottom of the clamping plate 4, and the guide rod 15 slides in conjunction with the guide groove 16.

[0029] Furthermore, the side wall of the rotating rod 7 is fixedly connected to the connecting frame 18, the connecting frame 18 has an opening at its center, and the connecting frame 18 is threadedly engaged with the adjusting bolt 19.

[0030] Furthermore, when the adjusting bolt 19 is tightened, the adjusting bolt 19 presses the abutment plate 20 against the bottom of the hollow frame 6; when the adjusting bolt 19 is loosened, the abutment plate 20 does not contact the adjusting bolt 19 and the hollow frame 6.

[0031] Furthermore, the bottom of the hollow frame 6 is fixedly connected to the transmission end of the electric push rod 2, and the electric push rod 2 is fixedly mounted on the fixed base 1.

[0032] Furthermore, there are at least two sets of electric actuators 2, symmetrically arranged along the geometric center of the hollow frame 6.

[0033] During operation, when reinforcement of the water pipeline is required, the electric actuator 2 is turned on via an external control switch, causing it to rotate and vertically lift the fixed frame 3. The fixed frame 3 is then placed on the outside of the water pipeline, positioning the clamping arc plate 4 at both ends of the pipeline to be reinforced. The adjusting bolt 19 is then tightened, causing the clamping plate 20 to descend vertically and disengage from the outside of the hollow frame 6. This causes the rotating rod 7 to rotate, which in turn causes the transmission rod 10 and the transmission sprocket 8 fitted to its surface to rotate inside the hollow frame 6. Combined with the meshing transmission action of the transmission chain ring 9 on the transmission sprocket 8 and the follower sprocket 11, the transmission rods 10 on both sides of the hollow frame 6 rotate synchronously and in the same direction, thereby driving the bidirectional lead screw 12 to rotate synchronously and in the same direction. After rotating inside the transmission frame 5, the lifting sleeve 13 can move vertically in opposite directions inside the hollow frame 6 under the guidance and limiting action of the limiting groove 21 on the pushing rod 14, and under the rotational transmission action of the double screw 12 on the lifting sleeve 13. Subsequently, under the transmission conversion action of the pushing rod 14, the vertical movement force of the lifting sleeve 13 can be converted into a horizontal pushing force on the clamping arc plate 4, thereby driving the two sets of clamping arc plates 4 to move horizontally in opposite directions and fit against the outside of the water conservancy pipeline to be reinforced, thus clamping and fixing the water conservancy pipeline. Then, the adjusting bolt 19 is turned in the opposite direction to drive the abutment plate 20 to move vertically in opposite directions and fit against the outside of the hollow frame 6, thus fixing and limiting the rotating rod 7 and the transmission rod 10 and transmission sprocket 8 connected to its top.
