Description

Technical Field

[0001] This utility model relates to the field of mineral exploration technology, and in particular to a support device for underground roadway drilling rigs. Background Technology

[0002] As an essential exploration machine in underground mining, tunnel drilling rigs complete mining operations through drilling. Due to the complex terrain and narrow space within underground tunnels, tunnel drilling rigs require support devices for installation and fixation. Existing support devices typically use sleepers to elevate the rear end of the tunnel drilling rig's base, and an I-beam support frame to support the front end of the base. Support rods are installed on the I-beam support frame to brace against the tunnel roof surface.

[0003] However, the aforementioned support device requires the use of multiple sleepers to raise the structure layer by layer, resulting in a loose structure and poor stability. Furthermore, the entire device has a simple structure and cannot adjust the drilling angle of the drilling rig according to different mining interfaces, thus deviating from the optimal mining position and affecting the mining quality. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a simple structure, good support effect, stable drilling operation, and adjustable drilling angle support device for underground roadway drilling rigs.

Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 As shown, the tunnel drilling rig 10 includes a base and a drilling rig assembly slidably disposed along the length of the base; this utility model provides a support device for an underground tunnel drilling rig, used to support the aforementioned tunnel drilling rig 10, such as... Figures 1-3As shown, it includes a support base body 1, a front vertical support rod 2, a front horizontal support rod 4, a rear vertical support rod 3, and a rear vertical support rod 5. The support base body 1 is placed horizontally on the roadway floor. There are at least two front vertical support rods 2, which are fixed side by side at the front end of the support base body 1. There are at least two rear vertical support rods 3, which are rotatably arranged side by side at the rear end of the support base body 1. Specifically, in this scheme, there are two front vertical support rods 2 and two rear vertical support rods 3, which are symmetrically arranged on both sides of the support base body 1. The front horizontal support rod 4 is connected to each front vertical support rod 2 via a first height adjustment component 6, and the rear horizontal support rod 5 is connected to each rear vertical support rod 3 via a second height adjustment component 7. The roadway drilling rig 10 is set above the front horizontal support rod 4 and the rear horizontal support rod 5, and the front end of the base of the roadway drilling rig 10 is rotatably connected to the front horizontal support rod 4 via a first rotating component 8, and the rear end of the base of the roadway drilling rig 10 is rotatably connected to the rear horizontal support rod 5 via a second rotating component 9. As shown in the figure, the support device, consisting of the support base body 1, the front vertical support rod 2, the rear vertical support rod 3, the front horizontal support rod 4, and the rear horizontal support rod 5, has a simple structure. Compared with the existing sleeper-supported method, its metal frame structure is stable and reliable. At the same time, the height adjustment of the front horizontal support rod 4 and the rear horizontal support rod 5, as well as the angle adjustment between the rear vertical support rod 3 and the support base body 1, can be well coordinated with the tunnel drilling rig 10 to complete the adjustment of the drilling angle, thereby ensuring the optimal mining position and the mining quality.

[0023] Further preferably, in order to achieve a rotational connection between the rear vertical support rod 3 and the support body 1, such as... Figure 6 As shown, a horizontally arranged rotating rod 102 is fixed to the rear end of the support body 1. Specifically, the number and position of the rotating rods 102 correspond to the number and position of the rear vertical support rods 3. In this scheme, there are two rotating rods 102, which are welded and fixed to both sides of the support body 1. A connecting sleeve 301 is fixed to the lower end of the rear vertical support rod 3. The connecting sleeve 301 is sleeved on the corresponding rotating rod 102. The two are rotated relative to each other. The end of the rotating rod 102 extends out of the connecting sleeve 301 and is formed with an external thread. A limit nut 103 is connected to the external thread to limit the lateral translation of the rear vertical support rod 3.

[0024] Further preferred, such as Figure 2 and Figure 3 As shown, the support base body 1 is equipped with a lifting assembly to provide mechanical power for adjusting the angles of the rear horizontal support rod 5 and the rear vertical support rod 3. Specifically, the lifting assembly includes a lifting cylinder 11, a hinge seat 1101, and a rotating shaft 1102. The hinge seat 1101 is fixed in the middle of the support base body 1, and the rotating shaft 1102 is disposed through the bottom of the base of the tunnel drilling rig 10. Specifically, as shown... Figure 4As shown, connecting ear plates 1001 are welded to both sides of the bottom of the base. The connecting ear plates 1001 are located near the rear end of the base. The two ends of the rotating shaft 1102 are rotatably mounted on the connecting ear plates 1001. The base of the lifting cylinder 11 is rotatably connected to the hinge seat 1101 via the lower ear plate, and the output end of the lifting cylinder 11 is rotatably connected to the rotating shaft 1102 via the upper ear plate. Driven by the lifting cylinder 11, the base of the tunnel drilling rig 10 rotates with the front horizontal support rod 4 as the rotating axis, and its rear end rises and falls, driving the rear vertical support rod 3 to change its angle until the tunnel drilling rig 10 reaches the angle position required for drilling. In this embodiment, the lifting cylinder 11 is a hydraulic cylinder. In other embodiments, an electric push rod can also be used.

[0025] In a further preferred embodiment, in order to facilitate manual lifting of the tunnel drilling rig 10 and reduce the force on the lifting cylinder 11 in the vertical direction during angle adjustment, a handle is provided at the rear end of the base supporting the tunnel drilling rig 10. The handle is fixed to the upper surface of the base supporting the tunnel drilling rig 10 by bolts.

[0026] like Figure 3 and Figure 5 As shown, the first height adjustment component 6 includes a first front clamping plate 601 fixed to the end of the front transverse support rod 4, a first rear clamping plate 602 mating with the first front clamping plate 601, and a first locking bolt 603 for connecting and fixing the first front clamping plate 601 and the first rear clamping plate 602. The mating surfaces of the first front clamping plate 601 and the first rear clamping plate 602 are provided with first semi-cylindrical holes. The two first semi-cylindrical holes are fitted onto the outside of the front vertical support rod 2, realizing height adjustment of the front transverse support rod 4 on the front vertical support rod 2. The first rear clamping plate 602 has through holes on both sides of the first semi-cylindrical hole, and the first front clamping plate 601 has threaded through holes on both sides of the first semi-cylindrical hole. The first locking bolt 603 passes through the through holes and engages with the threaded through holes. As the first locking bolt 603 tightens, the two first semi-cylindrical holes move closer together. The height adjustment component 7 is tightened and locked after being clamped to the front vertical support rod 2. Alternatively, the second height adjustment component 7 can have the same structure as the first height adjustment component, including a second front clamping plate fixed to the end of the rear transverse support rod 5, a second rear clamping plate mating with the second front clamping plate, and a second locking bolt for connecting and fixing the second front and rear clamping plates. The mating surfaces of the second front and rear clamping plates are provided with second semi-cylindrical holes. These two semi-cylindrical holes fit around the outside of the rear vertical support rod 3 and clamp to the rear vertical support rod 3 as the second locking bolt is tightened. Of course, the first height adjustment component 6 and the second height adjustment component 7 can also adopt other structures to achieve height adjustment of the transverse support rod on the vertical support rod. The above structure is only the optimal choice in this solution.

[0027] like Figure 4and Figure 8 As shown, the first rotating component 8 includes a first upper clamping plate 801 fixed to the front end of the base of the tunnel drilling rig 10, a first lower clamping plate 802 mating with the first upper clamping plate 801, and a third locking bolt 803 for connecting and fixing the first upper clamping plate 801 and the first lower clamping plate 802. The mating surfaces of the first upper clamping plate 801 and the first lower clamping plate 802 are provided with third semi-cylindrical holes. The front transverse support rod 4 is a columnar rod. The two third semi-cylindrical holes are fitted onto the outside of the front transverse support rod 4 to achieve the rotational effect between the base of the tunnel drilling rig 10 and the front transverse support rod 4. The third lower clamping plate 802 has through holes on both sides of the third semi-cylindrical hole, and the first upper clamping plate 801 has threaded through holes on both sides of the third semi-cylindrical hole. The third locking bolt 803 passes through the through holes and engages with the threaded through holes. As the third locking bolt 803 tightens, the two third semi-cylindrical holes approach each other until they clamp and contact the surface of the front transverse support rod 4, thereby completing the tunnel drilling. Similarly, the second rotating member 9 has the same structure as the first rotating member 8, which includes a second upper clamping plate fixed to the rear end of the base of the tunnel drilling rig 10, a second lower clamping plate that abuts against the second upper clamping plate, and a fourth locking bolt for connecting and fixing the second upper clamping plate and the second lower clamping plate. The mating surfaces of the second upper clamping plate and the second lower clamping plate are provided with a fourth semi-cylindrical hole. Similarly, the rear transverse support rod 5 is also a columnar rod. The two fourth semi-cylindrical holes are fitted onto the outside of the rear transverse support rod 5 and clamp into contact with the rear transverse support rod 5 as the fourth locking bolt is tightened, thereby completing the fixation of the rear end of the tunnel drilling rig 10. After the drilling angle of the tunnel drilling rig 10 is adjusted, the position of the tunnel drilling rig 10 on the support device is fixed by tightening the third locking bolt 803 and the fourth locking bolt. This can further improve the stability of the support device when supporting the tunnel drilling rig 10 and prevent the tunnel drilling rig 10 from shifting laterally.

[0028] Furthermore, the first height component, the second height component, the first rotating component 8, and the second rotating component 9 adopt the same clamping plate structure, which facilitates batch processing and installation and saves design costs.

[0029] To ensure the support body 1 is placed more stably on the roadway floor, such as Figure 2 As shown, the support body 1 is provided with a plurality of height-adjustable feet 12. Specifically, there are four height-adjustable feet 12, which are distributed around the support body 1 and connected to the support body 1 via a support plate 101. The height-adjustable feet 12 are the same as those in the prior art, and adopt a bolt and double nut structure. The bolts pass through the through holes of the support body, and the double bolts are respectively fitted on the bolts on both sides of the support body.

[0030] like Figures 1-3As shown, to improve the support effect of this support device, it also includes a front support rod 13 and a front adjusting screw 14. The front support rod 13 and the front adjusting screw 14 are located on the front vertical support rod 2. The upper end of the front support rod 13 is fixed with a front support top plate 15, and the lower end of the front support rod 13 has a first lower internal thread. The upper end of the front vertical support rod 2 has a first upper internal thread. Figure 5 As shown, the two ends of the front adjusting screw 14 are threadedly engaged with the first lower internal thread and the first upper internal thread, respectively, and the thread directions of the first lower internal thread and the first upper internal thread are opposite. By adopting the reverse thread configuration at both ends of the front adjusting screw 14, the front support rod 13 can be quickly lifted by rotating the front adjusting screw 14. More preferably, in order to better rotate the front adjusting screw 14, multiple screw handles 1401 are fixed circumferentially in the middle of the front adjusting screw 14. When performing the lifting operation, one hand holds the front support rod 13, and the other hand quickly rotates the front adjusting screw 14 through the screw handles 1401. The front support rod 13 moves towards the front vertical support rod 2 and finally comes into tight contact with the top of the roadway through the front support plate 15, thereby increasing the lateral support force when the roadway drilling rig 10 is in use.

[0031] More preferably, the support device further includes a rear support rod 16 and a rear adjusting screw 17. The rear support rod 16 and the rear adjusting screw 17 are located on the rear vertical support rod 3. The upper end of the rear vertical support rod 3 has a second upper internal thread, and the lower end of the rear support rod 16 has a second lower internal thread. The upper end of the rear support rod 16 is connected to a rear support top plate 18 via an angle adjusting member 19. The two ends of the rear adjusting screw 17 are respectively threaded into the second lower internal thread and the second upper internal thread, and the second lower internal thread and the second upper internal thread... The threads are in opposite directions. Of course, a screw handle 1401 is also fixed on the rear adjusting screw 17. By rotating the rear adjusting screw 17, the upward operation of the rear support rod 16 can be completed quickly. It is worth noting that, due to the presence of the angle adjusting component 19, the angle between the rear support top plate 18 and the horizontal plane caused by the angle change of the rear vertical support rod 3 can be corrected, so that the rear support top plate 18 after the angle is corrected can be tightly connected to the top of the roadway, thereby further increasing the lateral support force when the roadway drilling rig 10 is used and ensuring the stability of the roadway drilling rig 10 during use.

[0032] Specifically, such as Figure 7As shown, the angle adjustment component 19 includes an adjustment seat 1901, an adjustment bolt 1902, and an adjustment nut 1903. The adjustment seat 1901 is fixed below the rear support top plate 18. A U-shaped slot 1904 is provided on the adjustment seat 1901. The upper end of the rear support top rod 16 has a plug-in part that mates with the U-shaped slot 1904. The adjustment bolt 1902 passes through the adjustment seat 1901 and the plug-in part and is connected to the adjustment nut 1903. By utilizing the elastic deformation of the metal adjusting seats 1901 on both sides of the U-shaped slot 1904, the adjusting nut 1903 is gradually tightened until the inner wall of the U-shaped slot 1904 contacts the outer wall of the insertion part, without the two rotating relative to each other. Of course, in order to reduce the deformation of the adjusting seat 1901, a shim can be placed on the adjusting bolt 1902 between the U-shaped slot 1904 and the insertion part to increase the friction. Simply rotate the adjusting nut 1903 one turn up or down to complete the angle positioning of the support top plate 18.

[0033] The following describes the operation method of this support device. Before using the tunnel drilling rig 10, the tunnel drilling rig 10 is placed separately from this support device in the tunnel, and the first lower clamping plate 802 and the second lower clamping plate are in a disassembled state. According to the drilling height required by the actual working conditions, the front transverse support rod 4 and the rear transverse support rod 5 are adjusted to the predetermined height, and the first locking bolt 603 and the second locking bolt are tightened. Figure 1 As shown, the tunnel drilling rig 10 is manually lifted onto the front transverse support rod 4 and the rear transverse support rod 5. The first lower clamping plate 802 and the second lower clamping plate are connected to the first upper clamping plate 801 and the second upper clamping plate respectively and are in a non-clamped state. The output end of the lifting cylinder 11 is connected to the upper ear plate set on the rotating shaft 1102, completing the assembly of the lifting assembly. One or two operators hold the handle 20 of the tunnel drilling rig 10, while another operator loosens the second locking bolt and opens the lifting cylinder 11. The lifting cylinder 11 lifts the rig, and the tunnel drilling rig 10 rotates around the front transverse support rod 4 to the required drilling angle. The second locking bolt, the third locking screw, and the fourth locking screw are then tightened. Bolts are used to adjust the angle of the tunnel drilling rig 10. The operator climbs up using auxiliary tools (such as a stool) to straighten the rear support top plate 18 (i.e., the upper surface is in a horizontal position) and tightens the adjusting nut 1903. The operator then rotates the two front adjusting screws 14 and the two rear adjusting screws 17 in sequence. The front support top rod 13 drives the front support top plate 15 to make tight contact with the top of the tunnel, and the rear support top rod 16 drives the rear support top plate 18 to make tight contact with the top of the tunnel, thus completing the support operation of the entire support device. The entire device has a simple structure, good support effect, and the tunnel drilling rig 10 runs stably on the support device. The adjusted drilling angle matches the optimal mining position.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
