[0034] In order to solve the problem of low construction efficiency of drilling with manual handheld tools, the present invention provides a drilling device for tunnel section drilling and an operating method thereof. The drilling device for tunnel section drilling and an operating method thereof are further described below with reference to specific embodiments and accompanying drawings.

[0035] See Figures 1 to 7 As shown, a drilling device for drilling a tunnel section comprises:

[0036] The bracket 1 is vertically extended, and a first sliding sleeve 5 is height-adjustably connected to the bracket 1;

[0037] a swing frame 2, one end of which is rotatably connected to the first sliding sleeve 5 to achieve swing motion relative to the bracket 1, and a swing axis of the swing frame 2 is perpendicular to the extension direction of the bracket 1;

[0038] The drilling rig 3 is slidably connected to the other end of the swing frame 2 in a direction parallel to the swing axis.

[0039] By adopting the above design, the bracket 1 is placed on the ground in front of the tunnel section when in use, and then the first sliding sleeve 5 can be adjusted to slide along the bracket 1 to adjust the height of the swing frame 2 and / or swing the swing frame 2, so that the drilling rig 3 is moved to the position where the drilling is required, and then the drilling rig 3 can be slid to drill the tunnel section. The entire operation process is mechanized. Compared with drilling with a traditional handheld drill rig 3, it consumes less physical energy for workers, shortens the operation time, and improves construction efficiency.

[0040] Among them, see Figure 1 As shown, there are two swing frames 2, and the two swing frames 2 are connected to the first sliding sleeve 5 so as to be relatively rotatable. There are two drilling rigs 3, and the two drilling rigs 3 are respectively connected to the other ends of the two swing frames 2.

[0041] The drilling equipment also includes a driving device for driving the two swing frames 2 to flip upward relative to each other, so that the two drilling rigs 3 move along the arc of the tunnel top arch;

[0042] The driving device includes two chain hoists 4, and the two chain hoists 4 are relatively connected to the top of the bracket 1. The chain ends of the two chain hoists 4 are respectively connected to the other ends of the two swing frames 2. The two chain hoists 4 are used to reel up the corresponding chain ends to pull the two swing frames 2 upward.

[0043] By adopting the above design, the chain hoists 4 on both sides are used to reel in the corresponding chain ends (the chain hoists 4 are existing equipment, and their principles are existing technology, which will not be described in detail here), thereby pulling the swing frames 2 on both sides to flip upward, thereby driving the drilling rigs 3 on both sides to move along the arc of the tunnel top arch, so that the drilling path of the drilling rig 3 can be arc-shaped, which is convenient for drilling operations on both sides of the tunnel section axis at the same time, thereby improving the drilling efficiency.

[0044] Among them, see Figure 1 and 4 As shown, the swing frame 2 includes a rotating arm 201, a sliding arm 203 and a support arm 202. The bracket 1 includes two oppositely arranged vertical rods 101. Each vertical rod 101 is provided with a first sliding sleeve 5. The rotating arm 201 extends along the swing axis, and the two ends of the rotating arm 201 are movably connected to the two first sliding sleeves 5 respectively. One end of the support arm 202 is fixedly connected to the rotating arm 201, and the other end is fixedly connected to the sliding arm 203. The drilling rig 3 is slidably connected to the sliding arm 203.

[0045] See Figure 7 As shown, the drill rig 3 includes a drill body 301 and a second sliding sleeve 302 . The second sliding sleeve 302 is slidably mounted on the outside of the sliding arm 203 . The drill body 301 is fixed on the second sliding sleeve 302 , and the drill head of the drill body 301 is parallel to the sliding arm 203 .

[0046] Specifically, in this embodiment, there are two support arms 202, and the two support arms 202 are respectively fixed to the two ends of the sliding arm 203. The two support arms 202, the rotating arm 201 and the sliding arm 203 are combined to form a square shape, which can improve the support force of the drilling rig 3.

[0047] By adopting the above design, the drill body 301 is slid along the length direction of the sliding arm 203 by the second sliding sleeve 302, so that the drill body 301 can be moved toward the tunnel section, thereby achieving drilling, and the drilling depth can be adjusted by sliding.

[0048] Among them, see Figure 1 、 2, 3 and 5, further comprising a first driving assembly 6 for driving the first sliding sleeve 5 to slide along the bracket 1 to achieve height adjustment, the first driving assembly 6 comprising a rack 601, a first gear 603 and a rotating shaft 602, the rack 601 being vertically arranged and fixed to the relative outer side of any vertical pole 101, the first gear 603 being rotatably connected to the upper portion of the corresponding first sliding sleeve 5, and the first gear 603 being engaged with the rack 601, the rotating shaft 602 being fixedly connected to the first gear 603, and by rotating the rotating shaft 602, the first gear 603 is rotated and crawls along the rack 601, thereby driving the two swing frames 2 to achieve height adjustment;

[0049] The first driving assembly 6 further includes a locking assembly 7 for fixing the first sliding sleeve 5 on the corresponding vertical pole 101;

[0050] Specifically, in this embodiment, a fixed sleeve 604 is fixed to the upper portion of the first sliding sleeve 5, and an opening is provided at one end of the fixed sleeve 604 facing the rack 601. The first gear 603 is rotatably connected to the interior of the fixed sleeve 604, and the portion of the first gear 603 extending out of the opening is engaged with the rack 601.

[0051] By adopting the above design, the first gear 603 is driven to rotate by rotating the rotating shaft 602, so that the first gear 603 can crawl up and down along the rack 601, thereby allowing the first sliding sleeve 5 to be raised and lowered along the vertical pole 101, thereby adjusting the height of the swing frame 2 to adjust the height position of the drilling rig 3.

[0052] Further, in this embodiment, see Figure 7 As shown, the drilling device further includes a second drive assembly 9 , which has the same structure as the first drive assembly 6 , except for lacking the locking assembly 7 .

[0053] Among them, the locking assembly 7 includes a movable cavity, a card plate and a driving member.

The card plate 703 is slidably connected to the movable cavity. The driving member is connected to the first sliding sleeve 5, and is used to drive the card plate 703 to slide along the movable cavity and pass through the opening to insert into the gap between two adjacent teeth in the corresponding rack 601, so as to fix the first sliding sleeve 5 on the bracket 1.

[0054] For details, see Figure 6As shown, the driving member includes a second gear 702, a rotating rod 701 and a row of teeth.

The row of teeth is fixed to the lower part of the card plate 703. The card plate 703 engages with the second gear 702 through the row of teeth. By rotating the rotating rod 701, the second gear 702 is driven to rotate. The card plate 703 can be driven toward the rack 601 by the row of teeth, so that the card plate 703 is inserted into the gap between two adjacent teeth on the rack 601. The driving member also includes an electric telescopic rod (not shown in the figure), which is fixed on the first sliding sleeve 5, and the driving end of the electric telescopic rod passes through the first sliding sleeve 5 and presses against the outside of the card plate 703, so that the card plate 703 can be firmly inserted into the gap, thereby improving the firmness of the first sliding sleeve 5 fixed to the bracket 1.

[0055] Among them, see Figure 1 As shown, there are two first drive assemblies 6 , and the two first drive assemblies 6 are respectively installed on the opposite outer sides of the two vertical poles 101 to respectively drive the sliding and locking of the two first sliding sleeves 5 .

[0056] Specifically, in this embodiment, refer to Figure 1 and 3 As shown, a transverse plate 8 is fixed to the opposite side of the two first sliding sleeves 5, and a sleeve 801 is fixed to both ends of the transverse plate 8. The two ends of the two rotating arms 201 are movably inserted into the two sleeves 801 at both ends of the two transverse plates 8, so that the two swing frames 2 are on the same horizontal line;

[0057] Furthermore, the bracket 1 also includes two top seats 102, two bases 103 and two hydraulic systems. The two hydraulic systems (not shown in the figure) are respectively fixed to the upper parts of the two upright poles 101, the two top seats 102 are respectively fixed to the driving ends of the two hydraulic systems, and the two bases 103 are respectively fixed to the lower parts of the two upright poles 101. When in use, the bases 103 are placed on the ground, and the top seats 102 are supported on the top of the tunnel by the hydraulic system to ensure that the upright poles 101 are fixed firmly. The hydraulic system can be a hydraulic cylinder.

[0058] By adopting the above design and using the two brackets 1 arranged in a front-to-back manner, the stability of the entire equipment can be greatly improved, and the drilling accuracy of the drill rig 3 can be improved.
