Description

Technical Field

[0001] The invention relates to the technical field of pipeline alignment devices, and in particular to a pipeline alignment device for pipe jacking construction. Background Art

[0002] Pipe jacking construction is a trenchless construction method. In trenchless pipeline construction, pipe jacking construction is often used. Working wells are set up at the starting and ending ends of the pipeline as the pipeline starting well and receiving well respectively. During construction, the pipeline is hoisted into the well and placed on the guide rail at the bottom of the well. With the help of the thrust of the main jacking cylinder, the pipeline is continuously advanced from the starting well through the soil layer along a predetermined trajectory, and pipe sections are continuously added until the front end of the pipeline reaches the receiving well, thereby completing the trenchless pipeline laying. After one section of the pipeline is pushed into the soil layer, the second section of the pipeline is lowered and pushed forward.

[0003] During the pipe jacking process, due to the size limitation of the working well and the material and transportation requirements of the pipeline, the length of the pipe section is usually several meters. After the pipeline is hoisted into the working well, it needs to be aligned with the pipeline that has been pushed into the soil before subsequent welding, jacking and other processes can be carried out, otherwise the pipeline line will deviate from the predetermined trajectory; the steel pipe or concrete pipe commonly used in pipe jacking is heavy, and is often hoisted to the steel guide rail at the bottom of the working well by a crane, and then the construction personnel direct the crane to adjust the position of the pipeline; when aligning the pipeline, the crane operation accuracy is low, and the construction personnel in the well are in great danger and labor intensity. The alignment indicators usually use the pipeline misalignment, the gap between the joints, and the position of the groove. Due to the limitations of the on-site environment, the efficiency of the construction personnel's command alignment is low, and the pipeline alignment accuracy is poor, which makes it difficult to fully meet the alignment index requirements, thereby affecting the subsequent welding or jacking quality; for the mandarin duck groove pipeline, the pipeline position must be adjusted before the crane is lifted to ensure that the groove is roughly aligned with the groove of the jacked pipeline, otherwise the pipeline cannot be rotated and aligned with the groove after being hoisted.

[0004] At present, the efficiency of construction personnel's command and alignment is low, and the pipeline alignment accuracy is poor, which makes it difficult to fully meet the alignment standards, thus affecting the quality of subsequent welding or jacking. Therefore, it is necessary to improve the pipeline alignment method. In view of this, we propose a pipeline alignment device for pipe jacking construction. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0043] See also Figure 1-9 The present invention describes the above technical solution in detail through the following embodiments:

[0044] A pipe alignment device for pipe jacking construction includes a bearing support 1 arranged in a working well 8, such as Figure 1 The mounting structure shown also includes:

[0045] The movable guide rail 101 is installed along the Y-axis direction of the supporting bracket 1;

[0046] The alignment component includes two pulley bracket units 2 slidably installed on the movable guide rail 101 through the Y-axis power source. Specifically, the pulley bracket unit 2 of this embodiment includes a base frame 21 connected to the connecting frame 3, and a pulley body 25 for sliding installation on the movable guide rail 101 is installed at the bottom of the base frame 21, and a first cylinder base 22 is installed on both sides of the base frame 21, and an X-axis cylinder 23 is installed on the first cylinder base 22 as an X-axis power source.

[0047] like Figure 7-Figure 9In the structure shown, an upper bracket unit 4 is installed for lifting above the two pulley bracket units 2 through an X-axis cylinder 23, and two rotating units 5 for supporting the jacking pipe 7 are symmetrically installed on the upper bracket unit 4. In this embodiment, the upper bracket unit 4 includes a horizontal mounting frame 41 with a through opening 411, and a guide plug 413 is installed below the horizontal mounting frame 41. An X-axis guide block 211 for inserting the guide plug 413 is installed on the base frame 21 to maintain lifting stability.

[0048] First connecting lugs 412 for connecting the output shaft of the X-axis cylinder 23 are provided on both sides below the horizontal mounting frame 41; the rotating unit 5 includes a mounting seat 52 movably mounted at the opening 411, and an electric roller 51 is rotatably mounted on the mounting seat 52. Each pair of electric rollers 51 is provided with a driving wheel and a driven wheel, and the rollers are covered with rubber to increase friction and prevent damage to the pipeline anti-corrosion layer; a second connecting lug 521 is provided below the mounting seat 52, and a Z-axis cylinder 42 is installed at a position corresponding to the opening 411 below the horizontal mounting frame 41 as a Z-axis power source. The second connecting lug 521 is connected to the output shaft of the Z-axis cylinder 42, and is used to adjust the position of the rotating unit 5 along the Z-axis through the Z-axis cylinder 42, that is, to adjust the jacking pipe 7 supported above to move along the Z-axis direction.

[0049] Specifically, Figure 8 As shown in the structure, in this embodiment, the Z-axis cylinder 42 is divided into two groups, each group has two sets of cylinders symmetrically distributed along the central axis of the pipeline, each set of cylinders can be controlled separately, and can drive the rotating unit 5 to move along the Z-axis direction. In this embodiment, a Z-axis groove 414 arranged along the Z-axis direction is provided on the horizontal mounting frame 41, and the mounting seat 52 is inserted into the Z-axis groove 414 through the tenon 53. Other embodiments can also replace the tenon 53 with a bolt structure. In order to ensure that its moving path along the Z-axis direction is stable and consistent and control the position of the pipeline axis, the front and rear groups of Z-axis cylinders 42 can be controlled separately to adjust the position of the pipeline on the YZ plane.

[0050] Note that Figure 8 and Fig. 9 In the structure shown, a Y-axis cylinder 9 is installed on the base frame 21 along the Y-axis direction through the second cylinder base 24 as a Y-axis power source. In other embodiments, the X-axis, Y-axis and Z-axis can use electric cylinders or pneumatic cylinders as replacement power sources. At the same time, a connecting seat 102 connected to the output shaft of the Y-axis cylinder 9 is installed on the supporting bracket 1, which is used to adjust the jacking of the jacking pipe 7 along the Y-axis direction. The Y-axis cylinder 9 can adjust the distance between the pipe to be jacked 7 and the jacking pipe 10 in the Y-axis direction; in the present application, the front and rear two groups of X-axis cylinders 23 can be controlled separately, and the pitch angle adjustment can be achieved by adjusting the different lifting displacements of the front and rear two groups of X-axis cylinders 23.

[0051] like Figure 1As shown in the structure, the jacking pipe 7 in this embodiment needs to be adjusted to align with the jacking pipe 10, the collar 6 is in a split form, and the corresponding ends of the jacking pipe 7 and the jacking pipe 10 are both provided with collars 6, and the two collars 6 are respectively provided with a locator and a positioning target, and the positioning target is a tool for identifying and positioning with the locator. Through the locator and the positioning target, the spatial position deviation of the pipe to be jacked and the jacking pipe 10 can be determined; the locator in this embodiment adopts a laser sensor installed on the collar 6 to complete the positioning and alignment operation, and the locator in other embodiments can also adopt a sensor or a high-definition camera that can measure distance and angle, such as a millimeter wave sensor.

[0052] The working principle of the pipe alignment device for pipe jacking construction of this embodiment is as follows: during construction, the pipe on the ground is prepared for hoisting, and the crane lifts the pipe to the top of the bearing bracket; the position adjustment of the jacking pipe 7 along the X-axis, Y-axis and Z-axis is realized by the alignment component, and the alignment positioning can be realized quickly and accurately in conjunction with the collar 6 equipped with a laser sensor, and the X, Y, and Z-axis three-dimensional coordinate difference and angle difference of the pipe to be jacked and the jacking pipe 10 are obtained, and the difference data is transmitted to the control system. The automatic control system belongs to the prior art, so it will not be described in detail, and can control the oil cylinder to complete the automatic positioning action; after alignment, the distance is adjusted so that the jacking pipe The groove 7 is aligned with the jacking pipe 10 to achieve the preset pipe misalignment, joint gap and groove quality; the jacking pipe 7 is aligned with the jacking pipe 10; when jacking, the pipes need to be welded. Currently, common welding grooves include V-shaped grooves, X-shaped grooves, mandarin duck grooves, etc. V-shaped grooves, X-shaped grooves, etc. are circularly symmetrical. After the steel pipes are aligned, welding can be carried out, while the mandarin duck grooves are not circularly symmetrical. Therefore, it is often necessary to rotate the steel pipes to ensure that the left and right grooves are aligned; if the jacking pipe 7 is a mandarin duck groove, the jacking pipe 7 can be driven by the rotating unit 5 to rotate to achieve pipe alignment, so that the groove position is aligned with the groove of the jacking pipe 10.

[0053] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
