[0002] The drilling and punching mechanism is mainly used for drilling holes in underground lanes or tunnels, such as drilling long anchor cables, blastholes, etc. on the lane wall. Due to the limited space in underground lanes, the extension distance of the drilling and punching mechanism of a single slide is very limited, and the drill rod needs to be continuously lengthened to achieve long-stroke drilling. However, the work of lengthening the drill rod will result in low overall drilling efficiency. In addition, the existing drilling and punching mechanism is usually a single drill bit, and the punching parts often need to be replaced in actual use. The overall adjustability of the drilling and punching mechanism is low, and the adjustment of the drilling position of the drilling mechanism is inconvenient. The punching equipment needs to be moved frequently to perform drilling operations at different positions and angles. The overall work efficiency is very low, and the ability to adapt to different working conditions is poor. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0027] The present invention discloses a long drilling and drilling mechanism, which can be used for drilling holes in coal mine lanes and tunnels in cooperation with equipment such as a tunneling machine. The following are specific embodiments:

[0028] The present invention is a drilling and punching mechanism, which realizes three-stage telescopic extension by providing three slideways that can move relatively and two drill rods. Under the premise that the required installation space remains unchanged, it is equivalent to lengthening the length of the slideway, thereby increasing the stroke of the drill rod. Furthermore, two drill rods can be provided on the drilling and punching mechanism, and different drill bits can be installed on the two drill rods to perform different types of drilling operations.

[0029] In order to achieve three-stage telescopic extension to increase the stroke of the drill rod, specific settings, such as Figure 1 , Figure 2 , Figure 4 As shown, the mechanism includes a base 3, a primary slide 1 sliding along the base 3, a secondary slide 2 sliding along the primary slide 1, and a motor base 4 sliding along the secondary slide 2. In a specific implementation, preferably, a slide groove is provided on the upper end surface of the base 3, and the primary slide 1 slides in the slide groove of the base 3. The upper and lower end surfaces of the primary slide 1 are both slide rails, the lower end surface of the secondary slide 2 is provided with a slide groove, the upper end surface is provided with a slide rail, and the lower end surface of the motor base 4 is provided with a slide groove. The slide groove on the lower end surface of the secondary slide 2 cooperates with the slide rail on the upper end surface of the primary slide 1 to slide. The slide groove on the lower end surface of the motor base 4 cooperates with the slide rail on the upper end surface of the secondary slide 2 to slide.

[0030] With the above-mentioned three-stage telescopic base, primary slideway, and secondary slideway, a drill rod and a driving mechanism can be installed on the motor base 4 as needed. A set of drill rods and driving mechanisms can be installed. Preferably, a first driving mechanism 15 for driving the first drill rod 5 to rotate and a second driving mechanism 16 for driving the second drill rod 6 to rotate are provided on the motor base 4. The first drill rod 5 and the second drill rod 6 are extended in opposite directions. The first driving mechanism 15 and the second driving mechanism 16 are generally provided as motors, and the first drill rod 5 and the second drill rod 6 are respectively installed on the output shafts of the motors. Drill bits are installed at the ends of the first drill rod 5 and the second drill rod 6 as needed. Figure 1 For example, when the motor base 6 moves to the left, the first drive mechanism 15 drives the first drill rod 5 to drill holes; when the motor base moves to the right, the second drive mechanism drives the second drill rod 6 to drill holes, thereby realizing bidirectional drilling of the same drilling and drilling mechanism. In this embodiment, it is preferably configured that the first drive mechanism and the second drive mechanism are arranged on the same motor base 4, thereby simplifying the structure and saving installation space. It is also possible to respectively provide a sliding base for the first drive mechanism and the second drive structure as needed. The provision of two drill rods enables the drilling mechanism to achieve different types of drilling. The two drill rods are arranged in opposite directions. In actual use, it is easy to control the drilling operation of the two drill rods, and the drilling of the drill rods can be switched without excessive adjustments, thereby improving the drilling efficiency.

[0031] The drilling mechanism is provided with a positioning component for positioning the first drill rod 5 and the second drill rod 6 when they are working. As shown in the figure, positioning components are provided at the outer end of the primary slide 1 and the outer end of the secondary slide 2. When the drill rods are drilling holes, the positioning part is pressed against the top plate of the excavation mechanism for support and positioning. The positioning component mainly includes a positioning plate 13 and a positioning head 14 fixed on the positioning plate 13. The positioning plates 13 are respectively fixed on the outer ends of the primary slide 1 and the secondary slide 2, and the positioning head 14 is provided on the positioning plate 13.

[0032] The drilling mechanism of the present invention is provided with a first drill rod 5 and a second drill rod 6. The provision of the two drill rods can increase the number of drill bits that can be installed. Drill bits can be installed on both the first drill rod 5 and the second drill rod 6. Preferably, the drill bit on the first drill rod 5 is of a different type from the drill bit on the second drill rod 6. For example, the first drill rod 5 is a drill bit for drilling long anchor cables, and the second drill rod 6 is a drill bit for drilling blastholes. Since the number of drill bits is increased and they are of different types, different types of holes can be drilled, which effectively reduces the time for replacing drill rods, and the two bidirectional drill bits can drill different holes, which improves the efficiency of drilling holes and improves the adaptability of a single device under different working conditions.

[0033] Furthermore, the drilling and punching mechanism is a bidirectional drilling mechanism, which requires a long extension stroke in both directions, which is achieved by the movement of the primary slide 1 and the secondary slide 2 and the motor base 4. A limit plate 17 is set at the tail end of the primary slide 1 and the secondary slide 2. The limit plate 17 can play a role in limiting and positioning. Figure 1 As shown, the first drill rod 5 and the second drill rod 6 of the drilling and perforating mechanism are preferably set as extended drill rods, and a straightening mechanism 18 is set for the first drill rod 5 and the second drill rod 6 to increase the rigidity of the first drill rod 5 and the second drill rod 6 and ensure that the first drill rod 5 and the second drill rod 6 are in a stable working state.

[0034] The drilling and punching mechanism in the present invention is usually installed on a roadheader or a drilling vehicle to work. In order to adapt to the narrow space of coal mine lanes and tunnels, it is necessary to adjust the angle in multiple directions. For this reason, the mechanism is designed accordingly.

[0035] First, the base 3 is set on the rotating base 8, and the rotating base 8 is driven to rotate by the rotating telescopic oil cylinder 7, and can rotate within a certain angle range in the plane where the base 3 is located.

[0036] Furthermore, the mechanism is provided with a support arm 9, which is connected to the excavation equipment through the support arm 9. The lower end of the support arm 9 is connected to the excavation equipment, and the upper end of the support arm 9 is provided with a rotary motor 10. The rotary seat 8 is directly or through corresponding accessories arranged on the rotating part of the rotary motor 10, and can be rotated around the axis under the drive of the rotary motor 10. Figure 2 , Figure 3 shown.

[0037] Preferably, the rotating seat 8 is arranged on the rotating motor 10 through corresponding accessories that can be flipped and adjusted. The rotating seat 8 is hinged to the ear seat 19 on the rotating part of the rotating motor 10 and is driven to flip by the flip telescopic cylinder 11; the flip telescopic cylinder 11 is hinged to the rotating seat 8 through a connecting rod 12. Specifically, an ear seat 19 is provided on the rotating part of the rotating motor 10, and is hinged to the ear seat 19 at the lower end of the rotating seat 8. A flip telescopic cylinder 11 is also provided, and a connecting rod 12 is hingedly provided at the telescopic end of the flip telescopic cylinder 11, and the other end of the connecting rod 12 is also hinged to the rotating seat 8. Under the extension and retraction of the flip telescopic cylinder 11, the components on the rotating seat 8 connected to the base 3 can be flipped around the hinge axis between the rotating seat 8 and the ear seat 19. The flip telescopic cylinder 11 also needs to rotate with the rotating part of the rotating motor 10. Specifically, Figure 2 , Figure 3 shown.

[0038] Furthermore, the support arm 9 in the present invention is preferably configured as a telescopic structure with adjustable length. Specifically, the support arm 9 includes a telescopic support seat 9-1 and a telescopic support rod 9-2 that moves along the telescopic support seat 9-1. The telescopic support seat 9-1 is connected to the excavation equipment, and the telescopic support rod 9-2 is sleeved in the telescopic support seat 9-1. The telescopic support rod 9-2 can move along the telescopic support seat 9-1 to adjust the height. The rotary motor 10 is disposed at the end of the telescopic support rod 9-2. Specifically, Figure 2 , Figure 3 shown.

[0039] The drilling and punching mechanism is usually installed on a tunnel boring machine, and the support arm is hingedly installed on the tunnel boring machine. It is driven by a driving component on the tunnel boring machine to rotate around an axis, thereby realizing the overall rotation of the drilling and punching mechanism.

[0040] The above structural design can realize multi-angle drilling through rotation, flipping and other adjustments without moving the position of the excavation equipment, further adapting to the drilling needs in the narrow space of tunnels and coal mine lanes, and improving the drilling efficiency.

[0041] The present invention sets a two-stage slideway and cooperates with the motor base at the same time, and two drill rods are arranged on the motor base, thereby improving the drilling efficiency. Both the two-stage slideway can extend and contract, thereby driving the motor base to move forward and backward, and a suitable drill rod is selected for drilling according to needs, and the two-stage slideway and the motor base move to realize the drilling of the drill rod. The slideway of the present invention cooperates with the setting of the motor base at the same time, so that the two drill rods arranged on the motor base can realize long-stroke drilling. The setting of the slideway and the motor base can be extended and retracted as needed when drilling, the drilling distance is well adjustable, and the maximum stroke of the drilling is improved.

[0042] The present invention mainly describes the setting of two-stage slideways, and can also be provided with three-stage slideways or more-stage slideways. The present invention can realize long-stroke punching and short-stroke punching, and the maximum punching distance is improved.

[0043] The present invention realizes long-stroke drilling in a narrow space by providing a two-stage slideway and a slidable motor base, and long-stroke drilling can be realized without adding a drill rod. At the same time, with the help of a rotating seat, a rotating motor and a support arm, the drilling position can be adjusted in multiple directions and angles. The present invention can also increase the stroke by adding a slideway according to the above setting principle while ensuring the strength of the drilling mechanism as needed.

[0044] The components of the present invention are reasonably arranged and highly adjustable, and are particularly suitable for drilling holes in limited spaces such as coal mine lanes and tunnels, and have good adaptability to different working conditions. The drilling and drilling mechanism has high overall drilling efficiency and good performance.
