Description

Technical Field

[0001] The utility model relates to the technical field of safety monitoring, in particular to a drilling device used in a narrow area. Background Art

[0002] During the engineering monitoring process, it is necessary to set up surface monitoring points at multiple locations for safety monitoring. When setting up surface safety monitoring points, electric drills are generally used to drill holes and set up monitoring points when encountering hard rocks or concrete roads.

[0003] When setting up surface monitoring points in open areas such as rock faces and roads, workers can simply drill holes with handheld electric drills, which is relatively easy to operate. In actual monitoring, it is also necessary to set up monitoring points in narrow areas such as upper and lower slots. The width of the slots is generally only 30 to 40 centimeters. When drilling holes, on the one hand, it is difficult for workers to enter narrow areas to operate the drill rig to drill holes. On the other hand, one monitoring position usually requires multiple monitoring points to be set up along the circumference. In narrow areas, it is inconvenient for workers to turn around, and it is difficult to operate when setting up multiple circumferential monitoring points.

[0004] Therefore, it is difficult to drill holes and set up monitoring points in a small area, which often affects the overall layout of the monitoring points. What’s worse, some people may abandon the layout of the monitoring points here, which fails to meet the location and quantity requirements of the design specifications, affecting the accuracy and safety of actual safety monitoring.

[0005] In summary, how to conveniently drill holes and arrange monitoring points in a small area is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a drilling device for a narrow area. The drilling device can be stably supported in the narrow area by a supporting base frame, and the drilling mechanism can be driven to drill holes by pushing the sliding structure. There is no need for manual penetration into the narrow area, which improves practicality, reduces the difficulty of drilling, and facilitates the arrangement of monitoring points. The anti-rotation mechanism can prevent the rotating disk from rotating during drilling to ensure safety.

[0007] In response to the above technical problems, the technical solution provided by the utility model is a drilling device for a narrow area, comprising a supporting base frame, a vertical supporting frame fixedly installed on the supporting base frame, a horizontal rotating disk rotatably installed on the upper end of the supporting frame, and the rotating axis of the rotating disk extends vertically, a sliding structure that slides in a horizontal direction is provided on the rotating disk, a drilling mechanism is fixedly installed on the sliding structure, the sliding structure can drive the drill bit of the drilling mechanism to penetrate into the working surface for drilling, and also includes a stop mechanism, which is used to limit the rotation of the rotating disk after the rotating disk rotates to the drilling position.

[0008] Furthermore, the rotation axis of the drill bit of the drilling mechanism intersects with the rotation axis of the rotating disk, and the sliding direction of the sliding structure is parallel to the axial direction of the drill bit.

[0009] Furthermore, the support frame includes a vertical support rod, a horizontal fixed disk is fixed to the upper end of the vertical support rod, a rotating shaft is provided at the center of the fixed disk, and the rotating disk is rotatably mounted on the rotating shaft.

[0010] Furthermore, the rotating disk is a gear-like structure, and the anti-rotation mechanism includes a driven gear meshing with the rotating disk, and the driven gear is rotatably mounted on the fixed disk through a driven shaft. A anti-rotation thread is provided on the upper part of the driven shaft, and a anti-rotation nut is screwed on the anti-rotation thread. The anti-rotation nut can press the driven gear downward to limit the rotation of the driven gear.

[0011] Furthermore, the anti-rotation nut is a butterfly nut, and a anti-rotation gasket is provided at the lower end of the anti-rotation nut.

[0012] Furthermore, the fixed disk is a disk-shaped structure.

[0013] Furthermore, the supporting base frame includes three supporting rods, and the three supporting rods constitute a triangular support structure.

[0014] Furthermore, the sliding structure comprises a slide rail arranged on the upper end surface of the rotating disk, a slide plate is slidably arranged on the slide rail, and the drilling mechanism is fixedly mounted on the slide plate.

[0015] Furthermore, a push plate is fixedly mounted on the upper end of the sliding plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The drilling device can be supported stably in a narrow area by supporting the base frame. The sliding structure can be used to drive the drill bit of the drilling mechanism to drill deep into the working surface. In actual use, the staff does not need to go deep into the narrow area to perform drilling operations. The point drilling can be completed by simply pushing the sliding structure to slide. At the same time, the rotating disk can be rotated to drive the drilling mechanism to rotate around the rotating axis, thereby changing the position of the drilling mechanism in the circumferential direction, so that the drilling mechanism can perform drilling operations at different circumferential positions, avoiding the difficulty of the staff to turn around and operate when drilling at different circumferential positions in a narrow area, thereby reducing the difficulty of setting up monitoring points in a narrow area.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0029] In this embodiment, if Figure 1 As shown, a sliding structure 5 that slides in the horizontal direction is provided on the rotating disk 3, and a drilling mechanism 6 is fixedly installed on the sliding structure 5. The sliding structure 5 can drive the drill bit 63 of the drilling mechanism 6 to drill deep into the working surface, and the drilling device also includes a rotation stop mechanism 7, which is used to limit the rotation of the rotating disk 3 after the rotating disk 3 rotates to the drilling position. In this way, in actual use, after the support base 1 is fixed in a narrow area, the staff does not need to go deep into the narrow area, but only needs to rotate the rotating disk 3 outside to align the drill bit with the drilling position, and then push the sliding structure 5 to drive the drill bit to move to complete the drilling.

[0030] At the same time, rotating the rotating disk 3 can drive the drilling mechanism 6 to rotate in the circumferential direction, thereby changing the circumferential position of the drilling mechanism 6, so that the drilling mechanism 6 can perform drilling operations at different circumferential positions, avoiding the difficulty of workers turning around to operate when drilling at different circumferential positions in a narrow area, thereby reducing the difficulty of setting up monitoring points in a narrow area. By using the anti-rotation mechanism 7, after the rotating disk 3 drives the drilling mechanism 6 to reach the specified drilling position, the rotation of the rotating disk 3 can be limited, thereby improving the stability and safety of drilling.

[0031] Preferably, in this embodiment, Figure 1 As shown, the support frame 2 includes a vertical support rod 21 and a horizontal fixed disk 22. In the present embodiment, the fixed disk 22 is a disc-shaped structure, wherein the horizontal fixed disk 22 is fixedly mounted on the upper end of the vertical support rod 21, a rotating shaft 4 is provided at the center of the fixed disk 22, and the rotating disk 3 is rotatably mounted on the rotating shaft 4. The lower end of the support rod 11 is fixedly connected to the support base frame 1. The support base frame 1 includes three support rods 11, the upper ends of the three support rods 11 are arranged at the lower end of the support frame 2 along a circumferential array, and the lower ends of the three support rods 11 extend outward to form a triangular bracket structure. Of course, in other embodiments, the shape of the fixed disk 22 can be set according to actual needs, such as square, oval, etc. In other embodiments, the support base frame 1 can also be a frame-shaped structure, which is not limited here, as long as it can ensure that the drilling device can be supported and fixed in a small area for operation.

[0032] In this embodiment, if Figure 2 As shown, a plurality of rotating shaft balls 8 are arranged between the rotating shaft 4 and the inner hole of the rotating disk 3, and a rotating cavity for arranging the rotating shaft balls 8 and rotating the rotating shaft balls 8 is formed between the rotating shaft 4 and the inner hole of the rotating disk 3, so that the rotating disk 3 is rotatably mounted on the rotating shaft 4 through the rotating shaft balls 8. Of course, in other embodiments, the rotating disk 3 can also be directly rotatably mounted on the rotating shaft 4 through a bearing.

[0033] In this embodiment, preferably, the rotating disk 3 is a gear-like structure with external teeth arranged on the outer periphery, the anti-rotation mechanism includes a driven gear 73 meshing with the rotating disk 3 , and the outer diameter of the rotating disk 3 is larger than the outer diameter of the driven gear 73 .

[0034] Specifically, Figure 3 As shown, the anti-rotation mechanism 7 includes an anti-rotation base 71 fixedly arranged on the fixed disk 22, a vertical driven shaft 72 is fixedly installed on the anti-rotation base 71, and a driven gear 73 rotates through the driven shaft 72, and is rotatably installed on the fixed disk 22, the upper part of the driven shaft 72 exposes the driven gear 73, and an anti-rotation thread 721 is arranged on the upper part, and the part of the driven shaft 72 in the inner hole of the driven gear 73 is still a bare rod structure. A anti-rotation nut 74 is spirally arranged on the anti-rotation thread 721, so that by screwing the anti-rotation nut 74, the anti-rotation nut 74 can press the driven gear 73 downward to limit the rotation of the driven gear 73, so as to facilitate the anti-rotation of the rotating disk 3.

[0035] In this embodiment, if Figure 4 As shown, a plurality of driven shaft balls 9 are arranged between the inner holes of the driven shaft 72 and the driven gear 73, and a rotating cavity for arranging the driven shaft balls 9 and rotating the driven shaft balls 9 is formed between the inner holes of the driven shaft 72 and the driven gear 73, so that the driven gear 73 is rotatably mounted on the driven shaft 72 through the driven shaft balls 9. Of course, in other embodiments, the driven gear 73 can also be directly rotatably mounted on the driven shaft 72 through a bearing.

[0036] Preferably, in this embodiment, the stop nut 74 is a butterfly nut, so that in actual use, it is convenient for the staff to manually loosen and tighten the stop nut 74. A stop gasket 75 is provided at the lower end of the stop nut 74, and the stop gasket 75 is used to facilitate the stop nut 74 to press and fix the driven gear 73.

[0037] In this embodiment, if Figure 1 , 2As shown, the sliding structure 5 includes two parallel slide rails 51 arranged on the upper end surface of the rotating disk 3, and a sliding plate 52 is slidably arranged on the two slide rails 51. The drilling mechanism 6 is integrally fixedly mounted on the sliding plate 52, and an upwardly extending push plate 53 is fixedly arranged at one end of the sliding plate 52 facing the rotating shaft 4, so as to facilitate pushing. Of course, in other embodiments, when meeting actual use requirements, only one slide rail 51 can be provided, or the push plate 53 can be provided at other positions of the sliding plate 52.

[0038] In this embodiment, if Figure 1 As shown, the drilling mechanism 6 includes a drilling machine body 61, and a drill rod 62 is rotatably provided at one end of the drilling machine body 61 facing away from the rotating shaft 4, and a drill bit 63 is provided at the end of the drill rod 62. Preferably, in this embodiment, the rotation axis of the drill bit intersects with the rotation axis of the rotating disk 3, and the sliding direction of the sliding structure 5 is parallel to the axial direction of the drill bit 63.

[0039] In this way, in the vertical section, the rotation axis of the drill bit 63 is coplanar and parallel to the radius of the rotating disk 3. Then, during the actual drilling operation, the direction of the reaction force transmitted from the working surface to the drilling mechanism 6 can be parallel to the radius of the rotating disk 3 and intersect with the axis of the rotating shaft 4, thereby avoiding the generation of a deflection force during drilling, causing the rotating disk 3 to deflect, and improving stability and safety. Of course, in other embodiments, when meeting actual use requirements, the rotation axis of the drill bit may not intersect with the axis of the rotating shaft 4, and at this time, the rotation of the rotating disk 3 can also be avoided by the action of the anti-rotation mechanism.

[0040] The working process of the present application is as follows: first, the support frame 1 is supported and fixed in a narrow area where the operation is required, then the rotating disk 3 is rotated, the drill bit 63 is aligned with the position where the hole needs to be drilled, and then the stop nut 74 is tightened to fix the stop position of the rotating disk 3.

[0041] The drilling mechanism 6 is started, the drill bit rotates, and the push plate 53 is pushed to the working surface to drill a hole.

[0042] When the hole is punched, the push plate 53 can be retracted to the initial position according to the needs, and the anti-rotation nut 74 can be loosened. The rotating disk 3 is rotated to another punching position in the circumferential direction, and the above action is repeated to punch holes at different points in the circumferential direction.

[0043] In summary, the drilling device of the utility model can support the drilling device as a whole stably in a narrow area by supporting the base frame 1, and the sliding structure 5 can be used to drive the drill bit 63 of the drilling mechanism 6 to penetrate into the working surface for drilling. In actual use, there is no need for the staff to penetrate into the narrow area for drilling operations, and the point drilling can be completed by simply pushing the sliding structure 5 to slide. At the same time, rotating the rotating disk 3 can drive the drilling mechanism 6 to rotate around the rotating axis 4, thereby changing the circumferential position of the drilling mechanism 6, so that the drilling mechanism 6 can perform drilling operations at different circumferential positions, avoiding the difficulty of the staff to turn around and operate when drilling at different circumferential positions in a narrow area, thereby reducing the difficulty of setting monitoring points in a narrow area, and utilizing the anti-rotation mechanism 7, after the rotating disk 3 drives the drilling mechanism 6 to reach the specified drilling position, the rotation of the rotating disk 3 can be limited, thereby improving the stability and safety of drilling.

Different from Embodiment 1, in this embodiment, the sliding structure includes a sliding groove opened on the upper end surface of the rotating disk. The sliding plate is slidably installed in the sliding groove. The drilling mechanism is driven to drill holes by pushing the sliding groove. At this time, it should be noted that the driven gear is located as a whole under the sliding groove to avoid interference between the drilling mechanism and the anti-rotation mechanism when the rotating disk rotates.

[0045] Embodiment 3. This embodiment provides an unused anti-rotation mechanism. Different from Embodiment 1, in this embodiment, a T-slot is provided on the bottom surface of the rotating disk, and an annular hole is provided at the position of the fixed plate corresponding to the T-slot. An adaptable T-bolt is provided in the T-slot. The lower end of the T-bolt extends out of the annular hole and is screwed with a anti-rotation nut. The rotating disk can be clamped and fixed on the fixed disk by tightening the anti-rotation nut.

[0046] Embodiment 4. This embodiment provides an alternative drilling device. Different from Embodiment 1, in this embodiment, the rotating disk may further include a linear drive mechanism, which is used to drive the slider to slide on the rotating disk. In this embodiment, the linear drive mechanism is a gear rack mechanism. Specifically, a rack is provided on one side of the slider, and a gear meshing with the rack is rotatably installed at a position of the rotating disk corresponding to the rack. The gear is driven to rotate by a driving motor, so that the slider can be driven to slide by the driving motor to complete the drilling. There is no need to manually push the slider to drill holes, which improves practicality.
