A directional crossing device for a gas network

Abstract

This disclosure relates to the field of gas pipeline technology. One embodiment of this disclosure provides a directional crossing device for gas pipelines, including a base. A circular shaft is movably sleeved on the left side inside the base. A vertical rod is fixedly sleeved on the middle of the outer surface of the circular shaft. The outer surface of the vertical rod is movably sleeved with the inner surface of the base. By setting up a circular shaft, a turntable, a diagonal rod, a movable rod, and a threaded rod, when the handle is turned, the turntable will rotate with the threaded rod as the axis. Since the outer surface of the threaded rod and the inner surface of the movable rod are threadedly sleeved, as the threaded rod rotates, the movable rod will move along the inner surface of the base with the diagonal rod, thereby causing the diagonal rod to generate a thrust on the turntable, pushing the turntable to rotate with the circular shaft, the vertical rod, and the support ring as the axis. This allows for the adjustment of the angle of the support ring, solving the technical problem in the prior art that the angle of the support ring cannot be adjusted.

Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of gas pipeline technology, and more specifically, to a directional crossing device for gas pipeline networks. Background Technology

[0002] Directional crossing of gas pipelines is a key technology for laying gas pipelines without excavation. Through precise guidance and efficient drilling, pipelines can be installed under underground obstacles (such as roads, rivers, buildings, etc.). Its working principle includes directional drilling, staged hole enlargement, and pipeline pullback. It has advantages such as trenchless construction, precise control, strong adaptability, safety and efficiency.

[0003] When carrying out directional crossing construction of gas pipeline networks, corresponding directional crossing devices are needed to provide auxiliary support for the gas pipeline during pipeline pullback, thereby facilitating the pullback. However, in actual use, there are still shortcomings. Since the gas pipeline enters the borehole at a certain angle during pullback, most existing support rings adopt a fixed structural design, which means that the angle of the support ring is fixed. When the gas pipeline is pulled back at different angles, the outer surface of the gas pipeline will experience greater resistance due to the fixed angle of the support ring, which is not conducive to the construction. Therefore, improvements are needed. Utility Model Content

[0007] As a preferred embodiment of this utility model, a locking block is movably connected to the top of the outer surface of the gear, a rectangular block is fixedly installed at the top of the locking block, a fixing frame is movably sleeved on the top of the outer surface of the locking block, the outer surface of the fixing frame is fixedly connected to the outer surface of the base, and the inner surface of the fixing frame is movably sleeved on the outer surface of the rectangular block.

[0008] As a preferred embodiment of this utility model, a pressure adjusting block is movably sleeved at the top of the fixed frame, a spring is fixedly installed at the bottom of the pressure adjusting block, and the other end of the spring is fixedly connected to the top of the rectangular block.

[0009] As a preferred technical solution of this utility model, the pressure regulating block is internally movably sleeved with a first lead screw, the top end of the first lead screw passes through the pressure regulating block and the fixed frame and extends to the outside of the fixed frame and is fixedly sleeved with a first handle, and the outer surface of the first lead screw and the inner surface of the top end of the fixed frame are threaded together.

[0010] As a preferred embodiment of this utility model, a base plate is fixedly installed at the bottom of the base, and anchor rods are fixedly sleeved at the four corners of the base plate. The number of anchor rods is four, and they are symmetrical about the center of the base plate.

[0011] As a preferred embodiment of this utility model, each of the four anchor rods has a protrusion movably sleeved at its bottom. A slider is fixedly installed at the bottom of the protrusion. The outer surface of the slider is movably sleeved with the inner surface of the anchor rod. A limit rod is movably sleeved inside the slider. The outer surface of the limit rod is fixedly sleeved with the inner surface of the anchor rod.

[0012] As a preferred embodiment of this utility model, a connecting rod is hinged to the middle of the top of the protrusion, and a round block is hinged to the other end of the connecting rod. The outer surface of the round block and the inner surface of the anchor rod are movably connected.

[0013] As a preferred embodiment of this utility model, an extension rod is fixedly installed at the center of the top of the circular block. The top of the extension rod passes through the anchor rod and extends to the outside of the anchor rod, and a crossbar is fixedly installed thereon.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. In this disclosure, by setting up a round shaft, a turntable, a diagonal rod, a movable rod, and a threaded rod, when the handle is turned, the turntable will rotate with the threaded rod as the axis. Since the outer surface of the threaded rod and the inner surface of the movable rod are threadedly connected, as the threaded rod rotates, the movable rod will move along the inner surface of the base with the diagonal rod, thereby causing the diagonal rod to generate a thrust on the turntable, pushing the turntable to rotate with the round shaft, the vertical rod, and the support ring as the axis. In this way, the angle of the support ring can be adjusted according to the inclination angle of the gas pipeline.

[0017] 2. In this disclosure, by setting a protrusion, a connecting rod, a round block, an extension rod, and a crossbar, when the second handle is turned, the second lead screw will rotate. Since the outer surface of the second lead screw and the inner surface of the crossbar are threaded together, as the second lead screw rotates, the crossbar will move along with the extension rod and the round block, thereby causing the connecting rod to move as well. This causes the connecting rod to exert a thrust on the protrusion, pushing the protrusion to move outward. In this way, the anchoring capacity of the anchor rod can be enhanced by the protrusion, thereby improving the stability of the anchor rod after it is inserted into the ground.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1 to 6 As shown, it illustrates a directional crossing device for a gas pipeline network according to an embodiment of the present disclosure, including a base 1. A circular shaft 2 is movably sleeved on the left side inside the base 1. A vertical rod 3 is fixedly sleeved on the middle of the outer surface of the circular shaft 2. The outer surface of the vertical rod 3 is movably sleeved with the inner surface of the base 1. A support ring 4 is fixedly installed at the top of the vertical rod 3. Turntables 5 are fixedly sleeved at the front and rear ends of the outer surface of the circular shaft 2, and there are two turntables 5. An inclined rod 6 is hinged to the right side of the middle of the back of the two turntables 5. A movable rod 7 is hinged to the other end of the inclined rod 6. The outer surface of the movable rod 7 is movably sleeved with the inner surface of the base 1. A threaded rod 8 is threaded into the middle end of the movable rod 7. The left and right ends of the threaded rod 8 pass through the base 1 and extend to the outside of the base 1.

[0033] The two turntables 5 are identical in shape and size, and the inclined rod 6 that is hinged to the turntables 5 is also identical in shape and size. This allows the inclined rod 6 to exert the same thrust on the two turntables 5 when it moves. The handle 10 makes it convenient for the operator to rotate the disc 9. The support ring 4 at the top of the vertical rod 3 is formed by hinged two identical semicircular frames and locked with bolts, which facilitates the insertion of the gas pipe. In addition, the inner surface of the support ring 4 is smooth, which facilitates the sliding of the gas pipe inside the support ring 4.

[0034] In some examples, a disc 9 is fixedly sleeved on the right end of the outer surface of the threaded rod 8, a handle 10 is fixedly installed on the top of the middle part of the right end of the disc 9, a stop 11 is fixedly installed on the left end of the threaded rod 8, the outer surface of the stop 11 is movably connected to the outer surface of the base 1, and a gear 12 is fixedly sleeved on the right side of the outer surface of the threaded rod 8, the outer surface of the gear 12 is movably connected to the outer surface of the base 1.

[0035] The cooperation between the stop 11 and the gear 12 will limit the rotation of the threaded rod 8, thereby ensuring the stability of the rotation of the threaded rod 8 and preventing the threaded rod 8 from separating from the base 1.

[0036] In some examples, a locking block 13 is movably connected to the top of the outer surface of the gear 12, a rectangular block 14 is fixedly installed on the top of the locking block 13, a fixing frame 15 is movably sleeved on the top of the outer surface of the locking block 13, the outer surface of the fixing frame 15 is fixedly connected to the outer surface of the base 1, and the inner surface of the fixing frame 15 is movably sleeved on the outer surface of the rectangular block 14.

[0037] The bottom end of the locking block 13 is an arc surface, and the locking block 13 is locked in the teeth on the outer surface of the gear 12. The rectangular block 14 and the fixing frame 15 provide support and limit for the locking block 13.

[0038] In some examples, a pressure regulating block 17 is movably sleeved at the top of the fixed frame 15, and a spring 16 is fixedly installed at the bottom of the pressure regulating block 17. The other end of the spring 16 is fixedly connected to the top of the rectangular block 14.

[0039] When the spring 16 is in a compressed state, the rectangular block 14 will be subjected to a downward force under the restoring action of the spring 16, thereby forcing the locking block 13 to move downward and engage with the gear 12.

[0040] In some examples, the pressure regulating block 17 is internally movably sleeved with a first lead screw 18, the top end of the first lead screw 18 passes through the pressure regulating block 17 and the fixed frame 15 and extends to the outside of the fixed frame 15 and is fixedly sleeved with a first handle 19, the outer surface of the first lead screw 18 and the inner surface of the top end of the fixed frame 15 are threaded together.

[0041] The distance between the first handle 19 and the fixed frame 15 is equal to the distance between the pressure regulating block 17 and the rectangular block 14, so that the pressure regulating block 17 can move to the rectangular block 14 to the maximum extent.

[0042] In some examples, a base plate 20 is fixedly installed at the bottom of the base 1, and anchor rods 21 are fixedly sleeved at the four corners of the base plate 20. There are four anchor rods 21, and they are symmetrical about the center of the base plate 20.

[0043] The bottom ends of the four anchor rods 21 are conical, which makes it easier for operators to insert the anchor rods 21 into the ground.

[0044] In some examples, the bottom of the four anchor rods 21 are respectively movably fitted with protrusions 22, and the bottom end of the protrusions 22 is fixedly installed with sliders 23. The outer surface of the sliders 23 is movably fitted with the inner surface of the anchor rods 21. The inside of the sliders 23 is movably fitted with limit rods 24, and the outer surface of the limit rods 24 is fixedly fitted with the inner surface of the anchor rods 21.

[0045] The presence of slider 23 and limit rod 24 will limit the movement of protrusion 22, thereby ensuring the stability of protrusion 22 when it moves outward.

[0046] In some examples, a connecting rod 25 is hinged to the middle of the top of the protrusion 22, and a circular block 26 is hinged to the other end of the connecting rod 25. The outer surface of the circular block 26 and the inner surface of the anchor rod 21 are movably connected.

[0047] Both the outer surface of the circular block 26 and the inner surface of the anchor rod 21 are smooth, thus ensuring that the circular block 26 will not get stuck when moving along the inside of the anchor rod 21.

[0048] In some examples, an extension rod 27 is fixedly installed at the middle of the top of the circular block 26. The top of the extension rod 27 passes through the anchor rod 21 and extends to the outside of the anchor rod 21, and a crossbar 28 is fixedly installed thereon. There are two crossbars 28, and they are the same in shape and size.

[0049] The crossbar 28 is used to connect the extension rod 27, thereby ensuring that the two extension rods 27 on the front and rear sides of the base plate 20 can move synchronously.

[0050] In some examples, the inner thread of the middle end of the crossbar 28 is fitted with a second lead screw 29, the bottom of the outer surface of the second lead screw 29 is movably fitted with the inner surface of the base plate 20, and the top of the outer surface of the second lead screw 29 is fixedly fitted with a second handle 30, the bottom end of the second handle 30 is movably connected with the top end of the crossbar 28.

[0051] The bottom of the second lead screw 29 is I-shaped, which ensures that the second lead screw 29 will not wobble when it rotates.

[0052] Working principle and usage process of this utility model:

[0053] In use, the operator first inserts the anchor rod 21 into the ground, then turns the second handle 30, causing the second lead screw 29 to rotate along the inner surface of the base plate 20. This causes the crossbar 28, which is threaded onto the outer surface of the second lead screw 29, to move along the inner surface of the anchor rod 21 via the extension rod 27, carrying the top of the round block 26 and the connecting rod 25. This causes the bottom end of the connecting rod 25 to exert a thrust on the protrusion 22, pushing the protrusion 22 towards the outside of the anchor rod 21. This enhances the anchoring ability of the anchor rod 21 and improves its stability after being inserted into the ground.

[0054] The operator then moves the handle 10 according to the inclination angle of the gas pipeline, causing the disc 9 to rotate along the threaded rod 8. This causes the movable rod 7, which is threaded onto the outer surface of the threaded rod 8, to move one end of the inclined rod 6. This, in turn, causes the other end of the inclined rod 6 to exert a thrust on the turntable 5, pushing the turntable 5 through the circular shaft 2, causing the vertical rod 3 and the support ring 4 to rotate until the angle of the support ring 4 matches the inclination angle of the gas pipeline. As the threaded rod 8 rotates, the gear 12 will also rotate, causing it to press against the locking block 13. This, in turn, causes the locking block 13 to move along the inner surface of the fixed frame 15 along with the rectangular block 14, further compressing the spring 16. When the gear 1... 2. After the rotation stops, under the restoring action of the spring 16, the rectangular block 14 will return to its original position along with the locking block 13, thereby relocking the gear 12. Finally, the operator turns the first handle 19, causing the first lead screw 18 to rotate along the inner surface of the pressure regulating block 17. Since the first lead screw 18 is threadedly connected to the fixed frame 15, the pressure regulating block 17 will move towards the rectangular block 14 under the action of the first lead screw 18, thereby increasing the elastic force of the spring 16, improving the locking effect of the locking block 13, and preventing the gear 12 and the threaded rod 8 from rotating unexpectedly and causing the angle of the support ring 4 to change. In this way, the angle of the support ring 4 can be adjusted and locked according to the inclination angle of the gas pipeline.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
