DETAILED DESCRIPTION

[0037] 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.

[0038] like Figure 1 As shown, this embodiment provides a positioning and drilling device for railway roadbed construction, including a base 1, a positioning structure and a drilling structure.

[0039] Specifically, if Figure 1-Figure 2 As shown, the base 1 is a rectangular frame structure, and first through holes 11 are respectively provided on two opposite sides for adjustable connection drilling structures. A level bubble gauge 12 is arranged on the upper end surface of one side of the base 1 where the first through hole is not provided, which can keep the base level during the drilling operation, and is convenient for drilling in railway roadbed construction operations; an inverted U-shaped push rod 13 is connected to the other side of the base 1 where the first through hole is not provided. The push rod 13 can be configured to be fixed to the base 1. Four universal wheels 14 are installed under the base 1, which can facilitate the movement of the device to the position to be drilled in the railway roadbed construction.

[0040] Specifically, if Figure 1-Figure 3As shown, the positioning structure is used to fix the base 1 to the perforated position of the railway roadbed. The positioning structure includes a first connecting ear 2 fixed to the edge of the base 1, a support tube 3 threadedly connected to the first connecting ear 2, and an insertion rod 4 passing through the support tube 3 for inserting into the railway roadbed.

[0041] Furthermore, if Figure 3 As shown, the first connecting ear 2 is fixedly connected to the four corners of the base 1, and the first connecting ear 2 is provided with a first threaded hole 21 for threaded connection with the support tube 3; the support tube 3 is a cylindrical structure that is transparent from top to bottom, and a matching thread is arranged on the outer wall of the support tube 3. The insertion rod 4 includes a rod body 41 for inserting into the support tube 3, and a limit rod 42 fixedly connected to the side of the top end of the rod body 41. In the middle and upper part of the support tube 3, there are provided longitudinal channels 31 and a plurality of transverse positions 32 which are interconnected, and each transverse position 32 is distributed on both sides of the longitudinal channel 31; the limit rod 42 can slide along the longitudinal channel 31 or the transverse position 31. When fixing the base 1, the rod body 41 of the insertion rod 4 is inserted into the support tube 3, and the limit rod 42 is first moved downward in the longitudinal channel 31. When the rod body 41 is inserted to a suitable position of the railway roadbed, the limit rod 42 is rotated to the left or right so that the limit rod 42 is stuck in one of the transverse positions 32. At this time, the insertion rod is fixed, and the four positioning structures are all operated in this way, and the bubble of the level bubble meter 12 is located in the center to ensure the level of the base, thereby achieving the fixation of the base on the railway roadbed, which can effectively prevent the movement of the device during the drilling operation and avoid drilling errors.

[0042] Specifically, if Figure 1 , Figure 4 As shown, the drilling structure is located above the base 1 and is slidably connected to the base 1. The drilling structure includes a support frame slidably connected to the first through hole 11 of the base 1, and a drilling motor 5 and a drill rod 6 located in the center of the support frame; the support frame includes a top plate 7, a bottom plate 8, and four pillars 10 connecting the top plate 7 and the bottom plate 8, and an adjustment plate 9 is slidably connected along the four pillars 10, the drilling motor 5 is installed on the adjustment plate 10, and the drill rod 6 is connected to the output end of the drilling motor 5, and the drill rod 6 passes through the adjustment plate 10 and vertically downward.

[0043] Furthermore, if Figure 5As shown, the bottom plate 8 is an I-shaped plate structure, and the openings at both ends thereof are respectively fixedly connected with connecting plates 81, and each connecting plate 81 is respectively provided with a second through hole 82. In this embodiment, the second through hole 82 and the first through hole 11 are respectively long strip holes. By moving the bottom plate 8 to different positions of the base, and then passing the bolts through the first through hole 11 and the second through hole 82, the bottom plate 8 can be fixed to different positions of the base 1. The design of the first through hole 11 and the second through hole 82 of the two long strip holes enables the bottom plate 8 to be displaced and moved within a certain range on the bottom plate, and after fixing the base 1 of the device, the drilling position can be fine-tuned by moving the fixed position of the bottom plate 8 on the base 1 in the drilling structure.

[0044] The top plate 7 is a two-piece long plate structure; Figure 1 , Figure 4-Figure 7 As shown, the adjustment plate 9 is an I-shaped plate structure, and its four ends are respectively provided with second connecting ears 91, and the second connecting ears 91 are provided with third through holes 92 for sliding connection with the pillars 10. The top and bottom ends of the four pillars 10 are respectively fixed to the top plate 7 and the bottom plate 8. The first motor 71 and the second motor 72 are respectively provided on the two top plates 7, and the first motor 71 is connected to the first screw 73, and the second motor 72 is connected to the second screw 74. The first screw 73 and the second screw 74 are respectively penetrated and threadedly connected to the adjustment plate 9; the first motor 71 and the second motor 72 rotate synchronously, which can drive the adjustment plate 9 to rise and fall, and the drilling motor 5 and the drill rod 6 to rise and fall at the same time. The first motor 71 and the second motor 72 can be started or stopped at the same time by setting the same speed mode and rotation direction; a synchronous controller can also be used to connect the first motor 71 and the second motor 72, and the two motors and the synchronous controller can be started by adjusting the parameters of the synchronous controller, so that the first motor 71 and the second motor 72 can keep running synchronously.

[0045] In this embodiment, a first sleeve 93 is further arranged on the lower end surface of the adjustment plate 9, and the first sleeve 93 is located outside the upper portion of the drill rod 6. A second sleeve 83 is arranged on the bottom plate 8. The first sleeve 93 can be embedded in the second sleeve 83, and rises and falls in the second sleeve 83 as the adjustment plate 9 rises and falls. The structural design of the first sleeve 93 embedded in the second sleeve 83 in this embodiment can not only prevent dust, gravel and other debris from splashing during the drilling process, but also prevent the drill rod from accidentally injuring construction personnel when the drilling operation is not being performed.

[0046] A fourth through hole 84 is also provided in the middle of the bottom plate 8. The fourth through hole 84 is a threaded hole, and an external thread is also provided on the outer wall of the second sleeve 83, which is adapted to the thread of the fourth through hole 84. Therefore, the second sleeve 83 can be rotated in the fourth through hole 84 to achieve the rise and fall of the second sleeve 83 within a certain range, and the drilling and falling range of the drill stem 6 and the first sleeve 93 can be expanded within a certain range, thereby increasing the application scenarios.

[0047] Furthermore, in order to clearly observe the operation, the second sleeve 83 is designed to be fully transparent or partially transparent, which is convenient for observing the operation of the drill rod and effectively prevents the first sleeve 93 from touching the railway subgrade.

[0048] In this embodiment, a storage cavity 15 is also arranged on the base 1, which is a groove body with an upward opening, and can be used to place the insertion rod 4 when the device moves using the universal wheel 14, and can also be used to place other small tools used in the drilling operation.

[0049] The positioning and punching device for railway roadbed construction provided in this embodiment moves the device to the punching position by moving the universal wheel 14, inserts the insertion rod 4 in the positioning structure into the support tube 3, and uses the limit rod 42 to move downward along the longitudinal channel 31 to a suitable position, and then rotates the limit rod 42 to the left or right to make it stuck in one of the horizontal positions 32. The four positioning structures all adopt such operation, and make the bubble of the level bubble meter 12 located in the center to ensure the level of the base, so as to achieve the fixation of the base on the railway roadbed. In this embodiment, four positioning structures are used to fix the base to the railway roadbed, achieving the fixing effect of the entire device, which can effectively ensure that the entire device does not move during the drilling operation, and its stability can effectively avoid drilling errors during the construction process.

[0050] Subsequently, the bottom plate 8 in the support frame can be fine-tuned along the base 1 according to the drilling needs. The first through hole 11 and the second through hole 12 of the two long holes are designed so that the bottom plate 8 can be displaced within a certain range on the bottom plate, that is, the bottom plate 8 is moved to different positions of the base, and then bolts are passed through the first through hole 11 and the second through hole 12 to fix the bottom plate 8 at different positions of the base 1; the drilling position can be fine-tuned by moving the fixed position of the bottom plate 8 on the base 1 in the drilling structure.

[0051] In this embodiment, the drilling motor 5 and the drill rod 6 are supported by a support frame. The first motor 71 and the second motor 72 are operated synchronously to realize the lifting and lowering of the adjustment plate 9, thereby driving the lifting and lowering of the drilling motor 5 and the drill rod 6, effectively preventing the drill rod from deviating and ensuring the accuracy of drilling. During the descent of the drill rod 6, drilling operations on the railway roadbed can be carried out. During the operation, the first sleeve 93 is moved down and extended into the second sleeve 83, which can prevent dust, gravel and other debris from splashing during the drilling process, and can also prevent the drill rod from accidentally injuring construction personnel when no drilling operation is performed.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
