DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral structure; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0031] It should be noted that, in this document, except for the specific description shown in the figure, when directly referring to upper and lower, the “upper” refers to the direction away from the fastening ring 1 and closer to the telescopic cylinder 14, and the “lower” refers to the direction away from the telescopic cylinder 14 and closer to the fastening ring 1, for example Figure 1 shown.

[0032] See also Figure 1-8 The utility model provides a technical solution: a pipeline hole opening device, comprising: a fastening ring 1, which is used to fix the hole opening device on the pipeline and provide a basis for the installation of the hole opening device, the outer side of the fastening ring 1 is fixedly installed with an arc-shaped boss 2, and the arc-shaped recessed platform 3 is slidably installed on the arc-shaped boss 2. Preferably, the outer surface of the arc-shaped boss 2 and the inner surface of the arc-shaped recessed platform 3 are arcs of equal diameter, and more preferably, the center of the circular structure of the outer surface of the arc-shaped boss 2 and the inner surface of the arc-shaped recessed platform 3 is on the axial center line of the pipeline, that is, the position of the hole opening device is adjusted by sliding between the arc-shaped boss 2 and the arc-shaped recessed platform 3. Since the arc-shaped boss 2 has been fixedly installed on the pipeline by the fastening ring 1 at this time, the arc-shaped boss 2 provides most of the supporting force for the hole opening device, so it is relatively easy and convenient to adjust the position of the hole opening device at this time, and the relative position of the arc-shaped boss 2 and the arc-shaped recessed platform 3 can be fixed, thereby confirming the position of the hole opening device, and the arc-shaped recessed platform 3 is fixedly installed with a hole opener for opening a hole in the pipeline.

[0033] In some embodiments: a specific arc-shaped recess 3 and arc-shaped boss 2 structure is provided, a slide groove 5 is provided in the middle of the arc-shaped recess 3, a fastening column 4 is slidably installed in the slide groove 5, one end of the fastening column 4 is fixedly installed on the arc-shaped boss 2, the other end of the fastening column 4 extends out of the slide groove 5 and is slidably installed with a pressure plate 6, a clamping member 7 is installed on the upper side of the pressure plate 6, and the clamping member 7 squeezes the arc-shaped recess 3 and the arc-shaped boss 2 through the pressure plate 6, so that the arc-shaped recess 3 and the arc-shaped boss 2 are firmly combined and cannot slide relative to each other. Here, for example: the fastening column 4 can be a bolt structure, and the clamping member 7 is a nut structure, or: the clamping member 7 is an eccentric wheel structure and is installed at the end of the fastening column 4.

[0034] In some embodiments: the hole opener includes a side plate 8, the arc-shaped recessed platform 3 is fixedly installed at both ends of the side plate 8, a guide column 12 is fixedly installed on one side of the side plate 8, a guide sleeve 10 is slidably installed on the guide column 12, and the guide sleeve 10 is fixedly installed on the side of the driver 9 to limit the up and down movement trajectory of the driver 9. A lifting device is fixedly installed on the upper end of the side plate 8 for operating the up and down movement of the driver 9. The lifting device is connected to the driver 9 through a lifting rod 16, and a drill bit can be detachably installed at the lower part of the driver 9.

[0035] In some embodiments: In order to make the movement of the driver 9 more stable, especially when the drill bit drills through the pipe, the pipe instantly loses the reverse force on the drill bit, and the hole opener is prone to downward / forward rush, causing an impact on the lifting device. Therefore, an elastic element 11, such as a spring, a rubber bellows, etc., is provided on the lower side of the guide sleeve 10, which is sleeved on the guide column 12 below the guide sleeve 10.

[0036] One embodiment: a distance increasing mechanism 15 is provided.

[0037] In some embodiments: Generally, the length of the lifting rod 16 is the same as the movement distance of the driver 9, which results in a longer overall length of some hole-opening devices that require the driver 9 to move a long distance, making the hole-opening device relatively bulky and difficult to adjust. Therefore, the hole-opening device of the present application uses a distance-increasing mechanism 15 to reduce the length of the lifting rod 16, while the movement distance of the driver 9 will not be reduced. The lifting rod 16 is connected to the driver 9 via the distance-increasing mechanism 15.

[0038] In some embodiments: a specific structure of a distance increasing mechanism 15 is provided: the distance increasing mechanism 15 includes a first rack 1502, the first rack 1502 is arranged in a driving groove 1501, the driving groove 1501 passes through the middle of the side plate 8, the first rack 1502 is meshed with a gear 1503, and the driving groove 1501 provides space for the arrangement of the first rack 1502 and the gear 1503. Preferably, a groove 1505 is arranged on the lower side of the driving groove 1501, and the depth of the groove 1505 allows the first rack 1502 to pass through without penetrating the side plate 8, that is, the thickness of the side plate 8 is greater than the depth of the groove 1505, so that the side plate 8 is an integral structure, which increases the strength of the side plate 8, the first rack 1502 is fixedly installed on the side of the driver 9, and the gear 1503 also meshes with the second Rack 1504, the second rack 1504 is parallel to the first rack 1502, and the second rack 1504 is fixedly mounted on the side plate 8. When the gear 1503 moves downward, since the second rack 1504 cannot move, the gear 1503 rotates under the action of the second rack 1504, and the pitch circle movement length of the gear 1503 is equal to the downward movement distance of the gear 1503. Since the first rack 1502 can move, the rotation of the gear 1503 drives the first rack 1502 to move downward, and the gear 1503 also moves downward, so the downward movement distance of the first rack 1502 is twice the downward movement distance of the gear 1503. Therefore, when the lifting rod 16 is connected to the gear 1503, the length of the lifting rod 16 can be effectively shortened without shortening the movement distance of the driver 9.

[0039] In some embodiments, in order to make the movement between the gear 1503, the first rack 1502 and the second rack 1504 smoother, the gear 1503, the first rack 1502 and the second rack 1504 are helical teeth.

[0040] In some embodiments: a structure of a lifting device is provided, the lifting device adopts a telescopic cylinder 14, the telescopic cylinder 14 is fixedly installed on the upper part of the side panel 8, in some embodiments, the telescopic cylinder 14 can be installed through a support frame 13, that is, the support frame 13 is fixedly installed on the upper part of the side panel 8, the telescopic cylinder 14 is fixedly installed on the upper part of the support frame 13, the lifting rod 16 passes through the support frame 13, the lifting rod 16 serves as the telescopic rod of the telescopic cylinder 14, and the lifting rod 16 is rotatably connected to the gear 1503 through a U-shaped block 17.

[0041] In some embodiments: Since pipelines are often laid outdoors, it is sometimes necessary to manually push the driver 9 to move, so a manual lifting device structure is provided, the lifting device adopts a manual screw mechanism, the upper part of the side panel 8 is fixedly installed with a screw hole block 18, and the middle part of the screw hole block 18 is provided with a threaded hole for installing a lead screw. When the lead screw rotates, the lead screw is driven up and down under the action of the threaded hole provided in the screw hole block 18. Therefore, the lifting rod 16 is a lead screw, the lead screw is threadedly connected to the screw hole block 18 and passes through the screw hole block 18. One end of the lead screw is rotatably connected to the U-shaped block 17 to prevent the rotation of the lead screw from driving the U-shaped block 17 to rotate, and the U-shaped block 17 is rotatably installed with the gear 1503.

[0042] In some embodiments, in order to increase the movement stability of the U-shaped block 17 , a slider 1701 is provided on the side of the U-shaped block 17 , and the slider 1701 is slidably installed in the guide groove 801 , and the guide groove 801 is provided on the side of the driving groove 1501 .

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
