[0031] Embodiment

[0032] Please refer to Figures 1-4 , the present invention provides a pipeline burying device, including a support assembly 1, a lateral displacement assembly 2, a sliding table 3, a vertical displacement assembly 4, a clamping assembly 5, a jaw displacement assembly 6, and a connecting plate 8.

[0033] Further, the support assembly 1 includes a support plate 101 and universal wheels 102.

[0034] The support plate 101 is in a portal structure, with two support feet provided on both sides thereof, and at least two universal wheels 102 are installed at the bottom of the support feet.

[0035] The two support feet are erected on both sides of the buried trench for support, and are moved to different buried positions for operation through the universal wheels 102.

[0036] Further, a lateral displacement assembly 2 is provided on the top of the support plate 101. The moving member of the lateral displacement assembly 2 is a sliding table 3, so that the sliding table 3 can slide along the X-axis direction; a vertical displacement assembly 4 is provided on the sliding table 3. A connecting plate 8 is provided on the moving member of the vertical displacement assembly 4. A clamping assembly 5 is fixedly installed at the bottom of the connecting plate 8, so that the clamping assembly 5 can be displaced along the Y-axis direction through the vertical displacement assembly 4.

[0037] Preferably, when burying the pipeline, the sliding table 3 is displaced to one side of the support plate 101 through the lateral displacement assembly 2, and then the vertical displacement assembly 4 on the sliding table 3 works to drive the clamping assembly 5 to move downwards to clamp the pipeline placed on the ground on one side of the buried trench (in normal construction operations, the pipeline is placed on one side of the buried trench). Then the vertical displacement assembly 4 displaces and lifts the pipeline, and the lateral displacement assembly 2 displaces to move the pipeline above the buried position. Finally, it moves downwards into the buried trench through the vertical displacement assembly 4 to place the pipeline well.

[0038] Further, two clamping assemblies 5 are sequentially arranged on the connecting plate 8 along the Z-axis direction. Claw displacement assemblies 6 are correspondingly arranged on the clamping assemblies 5. The clamping assembly 5 includes a V-shaped claw 503, and the claw displacement assembly 6 can drive the V-shaped claw 503 to be displaced along the Z-axis direction.

[0039] Preferably, the pipeline to be buried is clamped by two clamping assemblies 5 to avoid excessive bending and damage of the clamped pipeline caused by a single clamping point. The claw displacement assembly 6 can drive the pipeline to be displaced along the buried trench through the V-shaped claw 503, which is convenient for adjusting the buried position of the pipeline and aligning and abutting with other already buried pipelines for quick installation.

[0040] Specifically, the clamping assembly 5 includes a claw cylinder 501, a claw connecting plate 502, a V-shaped claw 503, and a conveying chute 504.

[0041] The bottom surface of the connecting plate 8 is fixedly installed with a jaw cylinder 501 (specifically a wide jaw cylinder), and both sides of the jaw cylinder 501 are fixedly connected with jaw connecting plates 502. When the jaw cylinder 501 works, it drives the jaw connecting plates 502 on both sides to move towards or away from each other to achieve the clamping function; at the lower end of each jaw connecting plate 502, there is a V-shaped jaw 503, and the openings of the V-shaped jaws 503 on both sides are arranged facing each other, and different diameters of pipes can be adapted through their V-shaped openings.

[0042] In addition, at the position of the jaw connecting plate 502 corresponding to the V-shaped jaw 503, there is a conveying chute 504, and a slider is slidably matched in the conveying chute 504. The V-shaped jaw 503 is fixedly arranged on the slider, and the V-shaped jaw 503 on the slider slides in the conveying chute 504, and the sliding direction is along the Z-axis direction.

[0043] Specifically, the jaw displacement assembly 6 includes a cylinder 602 and a fixing plate 601.

[0044] The cylinder 602 is fixedly installed on the outer side surface of the jaw connecting plate 502. The push rod of the cylinder 602 is connected to one end of the fixing plate 601, and the other end of the fixing plate 601 is fixedly connected to the slider connected to the V-shaped jaw 503.

[0045] When the pipeline is buried in the trench and it is found that it is not aligned with the already buried pipeline, the cylinder 602 can be made to work to drive the V-shaped jaw 503 to displace in the conveying chute 504, so that the pipeline displaces along the length direction of the trench (i.e., the Z-axis direction) for butt joint installation.

[0046] In some feasible embodiments, the lateral displacement assembly 2 includes a first motor 201, a lateral screw 202, and a support seat 203.

[0047] Specifically, the first motor 201 is fixedly installed on one side of the top of the support plate 101. The drive shaft of the first motor 201 is fixedly connected to one end of the lateral screw 202, and the other end of the lateral screw 202 is rotatably connected to the support seat 203. The support seat 203 is fixedly arranged on the other side of the top of the support plate 101, and the axial direction of the horizontal screw is the X-axis direction.

[0048] The top of the support plate 101 is penetrated with a chute, and the chute direction is the X-axis direction. A sliding table 3 is slidably arranged in the chute. One end of the sliding table 3 is threadedly matched with the lateral screw 202. The lateral displacement assembly 2 can drive the sliding table 3 to displace towards both sides of the trench (i.e., the X-axis direction) to facilitate displacement above the pipes placed on both sides of the trench.

[0049] In some feasible embodiments, the vertical displacement assembly 4 includes a vertical screw 401, a drive screw 402, a second motor 403, and a guide post 404.

[0050] Specifically, the vertical screw 401 vertically penetrates through the sliding table 3 and the chute of the support plate 101 and is in threaded match with the sliding table 3. A second motor 403 is fixedly installed on the top of the sliding table 3. The driving shaft of the second motor 403 is fixedly connected with a driving screw 402. The driving screw 402 is in transmission connection with the two screws of the vertical screw 401. The bottom of the vertical screw 401 is rotatably connected to the top surface of the connecting plate 8.

[0051] The vertical screw 401 is driven to move through the double-screw transmission, so that the clamping assembly 5 on the connecting plate 8 undergoes vertical (i.e., in the Y-axis direction) displacement, lifting and transporting the pipeline on the ground. Through the meshing groove surfaces of the two screws, the pulling force and load-bearing capacity of the vertical displacement assembly 4 are increased, and the vertical displacement of the vertical screw 401 is prevented from being affected by the second motor 403.

[0052] In addition, a guide post 404 is also vertically penetrated through the sliding table 3 and the chute and is slidably connected to the sliding table 3. The bottom of the guide post 404 is fixedly connected to the top surface of the connecting plate 8. Since the vertical screw 401 needs to rotate during displacement, it is necessary to fix the direction of the connecting plate 8 rotatably connected to the vertical screw 401 to prevent the connecting plate 8 from rotating. Moreover, the guide post 404 can provide displacement guidance for the displacement of the vertical screw 401, enhancing the structural stability of the device.

[0053] In some feasible embodiments, a weight-increasing structure 7 is provided on the support feet on both sides of the support plate 101.

[0054] Specifically, the weight-increasing structure 7 includes a load-bearing ear plate 701, a load-bearing rope 702, an angle support plate 703, and a weight block 704.

[0055] The load-bearing ear plate 701 is fixedly installed at the top end of the support plate 101. There is a hanging hole on the load-bearing ear plate 701, and one end of the load-bearing rope 702 is sleeved in the hanging hole for load-bearing. The other end of the load-bearing rope 702 is sleeved with a weight block 704, and the number of the weight blocks 704 can be increased or decreased to adjust the weight. The middle part of the load-bearing rope 702 abuts against the vertex surface of the angle plate. The angle plate is fixedly installed on the support foot surface on the side of the support plate 101, so that the end of the load-bearing rope 702 sleeved with the weight block 704 is perpendicular to the ground, facilitating the placement of the weight block.

[0056] Since the pipeline is transported from one side of the trench to above the trench by the lateral displacement assembly 2 in this device, the center of gravity of the entire device is biased to one side during the transportation process, which easily causes the center of gravity on one side of the device to be overweight, resulting in the device tilting or collapsing. Therefore, it is necessary to place the weight block 704 for weight increase on the opposite side of the transportation side, so that the center of gravity deviation between the two sides of the device will not be too large, ensuring the normal progress of pipeline burial.

[0057] So far, the embodiments of the present utility model have been described in detail. To avoid obscuring the concept of the present utility model, some details well known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions of the present utility model based on the above description, and the scope of the present utility model is defined by the appended claims.
