Description

Technical Field

[0002] With the continuous expansion of the scale of water conservancy and hydropower projects and the increasing requirements for engineering quality, the accuracy and stability of pipeline connections face higher challenges. Traditional pipeline connection methods often rely on manual operations, using simple tools to align and fix pipeline interfaces. However, this method has many disadvantages;

[0003] The accuracy of manual alignment is limited, and it is difficult to ensure that the pipe interface is completely aligned. Slight deviations may cause leakage at the interface under long-term use or high-pressure water flow, affecting the operating efficiency and safety of the entire water conservancy and hydropower system. On the other hand, during the pipe connection process, the lack of effective fixing devices makes it easy for the pipe to move due to external forces during connection, increasing the difficulty of connection and construction time;

This seriously restricts the efficient promotion and quality improvement of water conservancy and hydropower project construction. Therefore, a new type of water conservancy and hydropower pipeline interface auxiliary connection and fixing device is urgently needed to solve these problems. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1-7As shown, an auxiliary connection and fixing device for the interface of water conservancy and hydropower pipelines is provided, including a bottom plate 1, a sliding opening 2 is symmetrically slidably connected to the upper surface of the bottom plate 1, a sliding block 3 is slidably connected inside the sliding opening 2, and a pipe rack device 4 is fixedly connected to the upper surface of the sliding block 3, and limited circular cavities 5 are symmetrically fixedly connected to the two sides of the bottom plate 1, and slide plates 6 are slidably connected inside the limited circular cavities 5, and cylinders 7 are fixedly connected to the opposite sides of the two slide plates 6, and the opposite ends of the two cylinders 7 penetrate into the interior of the adjacent sliding opening 2 and are fixedly connected to the outer side walls of the sliding block 3 respectively, and the outer side walls of the cylinders 7 are provided with limited springs 8 located inside the limited circular cavities 5, and the opposite ends of the limited springs 8 are fixedly connected to the outer side walls of the cylinders 7, and the opposite ends of the limited springs 8 are fixedly connected to the inner side walls of the adjacent limited circular cavities 5, and the front surface of the bottom plate 1 is fixedly connected to a wedge plate 9, The upper surface of the wedge plate 9 is fixedly connected with a motor 10, and the rear end of the output end of the motor 10 is fixedly connected with a threaded column 11. The upper surface of the wedge plate 9 is slidably connected with a transverse plate 12, and the front surface of the transverse plate 12 is fixedly connected with an internal thread cavity 13, and the rear end of the threaded column 11 extends to the inside of the internal thread cavity 13 and is connected with the internal thread of the internal thread cavity 13. The front surface of the pipe rack device 4 is fixedly connected with a semicircular block 14, and the outer wall of the semicircular block 14 is symmetrically fixedly connected with a raised round block 15. The outer wall of the semicircular block 14 is provided with a perforated rotating rack 16, and the inner part of the perforated rotating rack 16 is rotatably connected to the outer wall of the raised round block 15. Both ends of the transverse plate 12 are fixedly connected with a connecting plate 17, and the outer wall of the connecting plate 17 is symmetrically fixedly connected with a connecting round block 18, and the front section of the perforated rotating rack 16 is rotatably connected to the outer wall of the round block 18;

[0028] When the device is in the initial state, the limit spring 8 is in a natural extension state, the sliding block 3 is in a certain equilibrium position in the sliding port 2 due to the action of the limit spring 8 and the cylinder 7, and the pipe rack device 4 is in the corresponding position. The motor 10 is in the off state, the threaded column 11 and the internal threaded cavity 13 do not rotate relative to each other, the cross plate 12 is fixed, the semicircular block 14 is connected to the connecting circular blocks 18 at both ends of the cross plate 12 through the perforated rotating frame 16, and the entire device is ready for work. The two water conservancy and hydropower pipelines to be connected are placed on the two pipe rack devices 4 respectively. The pipe rack device 4 is used to support the pipeline so that it can maintain a stable position in subsequent operations. Start the motor 10, and the motor 10 drives the threaded column 11 to rotate. Since the threaded column 11 is threadedly connected to the internal threaded cavity 13 on the cross plate 12, and the cross plate 12 is restricted on the wedge plate 9 and can only slide forward and backward, as the threaded column 11 rotates, the cross plate 12 will move forward or backward on the wedge plate 9. When the horizontal plate 12 moves, the holed rotating frame 16 is driven to move through the connecting plate 17 and the connecting circular block 18. The holed rotating frame 16 rotates around the connecting circular block 18, and at the same time, since the holed rotating frame 16 is rotatably connected to the raised circular block 15 on the semicircular block 14, a force is applied to the semicircular block 14. After the semicircular block 14 is subjected to the force of the holed rotating frame 16, the sliding block 3 is driven to slide in the sliding port 2 through the pipe rack device 4. The sliding of the sliding block 3 will stretch the limit spring 8, and the cylinder 7 slides in the limit circular cavity 5 to ensure the stable movement of the sliding block 3. In this way, the two pipe rack devices 4 are driven to move closer to or farther from each other by the movement of the horizontal plate 12, thereby adjusting the positions of the two pipes so that their interfaces are accurately aligned, which is convenient for subsequent connection operations. After the pipeline connection is completed, the motor 10 is reversed to move the horizontal plate 12 in the opposite direction. Under the action of the limit spring 8, the sliding block 3 returns to the initial position, and the pipe rack device 4 also returns to the initial state, and the entire device is ready for the next use.

[0029] In this embodiment, the pipe rack device 4 includes a groove cavity 101, the outer wall of the groove cavity 101 is symmetrically provided with a sliding opening 102, the sliding opening 102 is slidably connected to a locking block 103, the outer wall of the locking block 103 is fixedly connected to a circular plate 104 with a hole, the outer wall of the locking block 103 is symmetrically provided with a clamping circular cavity 105, the outer wall of the clamping circular cavity 105 is symmetrically fixedly connected to a rotating circular block 106, the outer wall of the rotating circular block 106 is rotatably connected to the adjacent circular plate 104 with a hole, the outer wall of the clamping circular cavity 105 is in contact with the inner wall of the groove cavity 101, and the inner part of the groove cavity 101 is symmetrically fixedly connected to a support block 201 The lower surface of the locking block 103 is symmetrically provided with a sliding cavity 202, the interior of the sliding cavity 202 is slidably connected with a sliding plate 203, the lower surface of the sliding plate 203 is fixedly connected to the upper surface of the support block 201, the upper surface of the sliding plate 203 and the inner upper surface of the sliding cavity 202 are fixedly connected with a spring 1 204, a plurality of supporting card cavities 301 are provided on the left side of the left sliding cavity 202, a supporting card slot 302 is provided on the left side of the left sliding plate 203, a double-sided wedge block 303 is slidably connected to the interior of the supporting card slot 302, and a spring 2 304 is directly fixedly connected to the right side of the double-sided wedge block 303 and the interior of the supporting card slot 302;

[0030] When it is necessary to place the pipeline on the pipe rack device 4, the pipeline is placed in the groove cavity 101. Under the action of this downward pressure, the locking block 103 will slide downward in the sliding opening 102. When the locking block 103 slides downward, the sliding plate 203 below it slides relatively in the sliding cavity 202, and the spring 1 204 is stretched. At the same time, when the left sliding plate 203 moves to the left, when the double-sided wedge block 303 in the supporting card groove 302 moves to a suitable position, it will be clamped into the corresponding supporting card cavity 301 under the action of the spring 2 304, thereby fixing the position of the locking block 103, so that the clamping circular cavity 105 tightly clamps the pipeline, and the pipeline is fixed in the pipe rack device 4.

[0031] In this embodiment, a plurality of limiting grooves 401 are provided on the right side of the inner side wall of the right sliding cavity 202, a limiting elastic groove 402 is provided on the right side of the right sliding plate 203, a limiting clamping block 403 is slidably connected inside the limiting groove 401, a compression spring 404 is fixedly connected between the left side of the limiting clamping block 403 and the inside of the limiting groove 401, a reset groove 405 is symmetrically provided on the right side of the locking block 103, an extrusion plate 406 is slidably connected inside the reset groove 405, a pressing block 407 is fixedly connected to the right side of the extrusion plate 406, a plurality of extrusion plates 408 are fixedly connected to the left side of the pressing block 407, the left ends of the limiting extrusion plates 408 all penetrate into the inside of the limiting groove 401, and are fixedly connected to the limiting release block 409, and a plurality of reset springs 410 are fixedly connected to the left side of the extrusion plate 406 and the inside of the reset groove 405;

[0032] When the sliding plate 203 slides outward, the limiting block 403 slides in the limiting spring groove 402 and the limiting groove 401 under the action of the compression spring 404, further ensuring the stability of the movement of the sliding plate 203, so that the clamping circular cavity 105 tightly clamps the pipe, and the pipe is fixed in the pipe rack device 4. When the pipe needs to be taken out, the pressing block 407 is pressed. The pressing block 407 moves to the right, driving the extrusion plate 406 to compress the reset spring 410 in the reset groove 405. At the same time, the extrusion plate 408 and the limiting release block 409 move to the right with the movement of the pressing block 407, and the limiting release block 409 squeezes the limiting block 403, so that it compresses the compression spring 404 and completely retracts into the limiting groove 401, releasing the limit on the right sliding plate 203. Then, the double-sided wedge block 303 is pushed out of the supporting cavity 301 to overcome the elastic force of the spring 2 304, and the locking block 103 is released. Afterwards, under the restoring force of spring 1 204, locking block 103 returns to the initial position, and clamping circular cavity 105 releases the pipe, so that the pipe can be taken out smoothly. When pressing block 407 is released, under the action of reset spring 410, squeeze plate 406, pressing block 407 and other related components return to the initial position, and limiting block 403 returns to the initial limiting state under the action of compression spring 404.

[0033] In this embodiment, the inner side walls of the clamping circular cavity 105 are fixedly connected with anti-slip pads 107;

[0034] The anti-skid pad 107 is in close contact with the surface of the pipe, and its material has a high friction coefficient. When the clamping circular cavity 105 applies a clamping force to the pipe, the anti-skid pad 107 can increase the friction between the pipe and the anti-skid pad 107, further stabilizing the position of the pipe in the pipe rack device 4, preventing the pipe from sliding or shifting due to external forces during subsequent operations such as adjusting the position of the pipe by the device, and ensuring the accuracy and stability of the entire pipe connection operation.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
