Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a working arm for a chiseling and anchoring equipment trolley. Background Technology

[0002] Drilling and anchoring equipment trolleys are mainly used in underground engineering projects with high requirements for support quality, such as ore roadways and tunnel excavation. They are capable of precise drilling and anchoring work in tunnels, and are construction devices that integrate drilling, drill rod installation, grouting, and other functions. However, the drill rod installation length on the working arm of existing drilling and anchoring equipment trolleys is fixed, which makes drill rod installation difficult in some narrow working spaces and reduces work efficiency. Summary of the Invention

[0003] To address the problem of fixed drill rod installation length on existing anchor drilling equipment trolleys, which makes drill rod installation difficult in some narrow working environments, this utility model proposes an anchor drilling equipment trolley working arm where the distance between the front and rear top plates can be adjusted via a telescopic mechanism, thereby increasing the installation distance of the drill rod and expanding the application range of the device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A working arm for an anchor drilling trolley includes a sliding frame and a central cylinder. The central cylinder is slidably mounted on the sliding frame. A first telescopic mechanism is provided on the sliding frame. A front top plate is fixed to the telescopic end of the first telescopic mechanism, and a rear top plate is fixed to the rear end of the central cylinder. A second telescopic mechanism is provided between the front and rear top plates. The second telescopic mechanism passes through the sliding frame, with its front end on the front top plate and its rear end on the rear top plate. Both ends of the second telescopic mechanism are telescopic ends. A rock drilling device is mounted on the central cylinder, and a drill rod is installed on the rock drilling device. The front end of the drill rod passes through the front top plate. The front ends of both the first and second telescopic mechanisms can drive the front top plate to extend forward. After the first telescopic mechanism reaches its travel limit, the position of the front top plate is determined. At this point, the front end of the second telescopic mechanism continues to extend, pushing the entire central cylinder backward out of the sliding frame. Then, through the extension of the rear end of the second telescopic mechanism, the central cylinder continues to extend backward, thereby increasing the distance between the front and rear top plates.

[0005] Preferably, a sliding seat is slidably disposed inside the middle cylinder, and the rock drilling equipment is fixed on the sliding seat. A positioning plate is fixed to the front end of the middle cylinder, and rope pulleys are fixed to the sides of both the positioning plate and the rear top plate. A first mounting block and a second mounting block are fixed to the second telescopic mechanism. A first mounting seat is fixed to the sliding seat. A first rope is wound around the rope pulley of the positioning plate, with one end of the first rope fixed to the first mounting block and the other end fixed to the first mounting seat. A second rope is wound around the rope pulley of the rear top plate, with one end of the second rope fixed to the second mounting block and the other end fixed to the first mounting seat. The position of the rock drilling equipment on the middle cylinder is adjustable via the sliding seat, allowing for adaptability adjustments to the drill rod installation position and improving the applicability of the device.

[0006] Preferably, two rope wheels are fixed on the side of the positioning plate and arranged vertically to keep the upper and lower sides of the first rope horizontal, and two rope wheels are fixed on the side of the rear top plate and arranged vertically to keep the upper and lower sides of the second rope horizontal.

[0007] Preferably, a clamping seat is also fixed on the middle cylinder, and the drill rod passes through a through slot opened in the clamping seat. Two third telescopic mechanisms are symmetrically arranged on the side of the clamping seat, with the telescopic ends of the two third telescopic mechanisms facing the drill rod. This ensures the stability of the drill rod during movement.

[0008] Preferably, the working arm further includes a telescopic cylinder, the sliding frame is slidably mounted on the telescopic cylinder, and a fourth telescopic mechanism is provided in the telescopic cylinder. The telescopic end of the fourth telescopic mechanism is connected and fixed to the sliding frame. This allows for compensatory adjustments to the position of the front top plate.

[0009] Preferably, a first fixed base is fixed to the lower side of the telescopic cylinder, and a pitch mechanism is hinged to the lower side of the first fixed base. The telescopic end of the pitch mechanism is hinged to the front end of the telescopic cylinder. A vertical first rotation mechanism is fixed to the lower side of the first fixed base, and a horizontal second rotation mechanism is fixed to the side of the first rotation mechanism. The pitch mechanism, the first rotation mechanism, and the second rotation mechanism work together to adjust the position of the front top plate, thereby completing drilling at multiple drilling positions.

[0010] Preferably, the working arm further includes a second mounting base and a main arm. A hinge rod is fixed on the second mounting base, and a first hinge seat is hinged to the rear end of the main arm. The first hinge seat is rotatably connected to the hinge rod. A first swing seat is fixed to the side of the first hinge seat. A fifth telescopic mechanism is hinged to the second mounting base. The telescopic end of the fifth telescopic mechanism is hinged to the first swing seat. A sixth telescopic mechanism is hinged to the lower side of the first hinge seat. A second hinge seat is fixed to the front end of the main arm. The output end of the sixth telescopic mechanism is hinged to the lower side of the second hinge seat. A second swing seat is fixed to the side of the second hinge seat. A seventh telescopic mechanism is hinged to the second swing seat. A third hinge seat is hinged to the front end of the second hinge seat. The output end of the seventh telescopic mechanism is hinged to the third hinge seat.

[0011] The beneficial effects of this utility model through the above technical solution are as follows: 1. In this utility model, the telescopic ends of the first and second telescopic mechanisms drive the front top plate forward. After the telescopic end of the first telescopic mechanism reaches its telescopic limit, the position of the front top plate is fixed. At this time, the telescopic end of the second telescopic mechanism extends forward again, driving the middle cylinder to slide backward out of the sliding frame. The telescopic end of the rear end of the second telescopic mechanism can continue to extend the middle cylinder backward, thereby adjusting the distance between the front and rear top plates, increasing the installation distance of the drill rod, realizing the installation of drill rods in some narrow working environments, and improving the applicability of this device.

[0012] 2. In this utility model, the sliding seat inside the middle cylinder extends backward. When the telescopic end of the second telescopic mechanism extends backward, the cooperation of the first rope, the second rope, and the rope wheel enables the rock drilling equipment on the sliding seat to move a distance twice that of the telescopic end of the second telescopic mechanism. This further increases the minimum and maximum distances between the rock drill and the front top plate when it retracts and extends, thus improving the applicability of this device.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 7 As shown, this embodiment provides a working arm for a chiseling and anchoring equipment trolley, including a sliding frame 1 and a middle cylinder 2. The middle cylinder 2 is slidably mounted on the sliding frame 1. A U-shaped sliding groove is opened on the sliding frame 1. The middle cylinder 2 slides in the upper half of the sliding groove. Two first telescopic mechanisms 3 are symmetrically fixed on the side of the sliding frame 1. The first telescopic mechanism 3 can be a hydraulic cylinder. A front top plate 4 is fixed to the telescopic end of the front end of the first telescopic mechanism 3. A rear top plate 5 is fixed to the rear end of the middle cylinder 2. A second telescopic mechanism 6 is provided between the front top plate 4 and the rear top plate 5. The second telescopic mechanism 6 passes through the lower half of the sliding groove on the sliding frame 1, with its front end hinged to the front top plate 4 and its rear end hinged to the rear top plate 5. Both the front and rear ends of the second telescopic mechanism 6 are telescopic ends. The second telescopic mechanism 6 can be a double-headed hydraulic cylinder. A rock drilling device 100 is provided on the middle cylinder 2. The rock drilling device 100 can be a rock drill, which is existing technology and will not be described in detail. A drill rod 200 is installed on the rock drilling device 100, with the front end of the drill rod 200 passing through the front top plate 4.

[0016] In this embodiment, the telescopic ends of the first telescopic mechanism 3 and the second telescopic mechanism 6 can drive the front top plate 4 to move forward. After the telescopic end of the first telescopic mechanism 3 reaches the telescopic limit, the distance between the front top plate 4 and the sliding frame 1 is fixed. At this time, the telescopic end of the second telescopic mechanism 6 will extend forward again and drive the middle cylinder 2 to slide backward out of the sliding frame 1.

[0017] Further, refer to Figure 4A sliding seat 7 is slidably disposed inside the middle cylinder 2. A sliding groove is opened inside the middle cylinder 2. The sliding seat 7 can be a trolley, and the wheels of the trolley can slide in the sliding groove of the middle cylinder 2. The rock drilling equipment 100 is welded and fixed to the sliding seat 7. A positioning plate 8 is fixed to the front end of the middle cylinder 2. Rope pulleys 9 are fixed to both sides of the positioning plate 8 and the rear top plate 5. A first mounting block 10 and a second mounting block 11 are fixed to the second telescopic mechanism 6. The first mounting block 10 and the second mounting block 11 are welded and fixed to the cylinder seat of the second telescopic mechanism 6. On the top, the first mounting block 10 is located in front of the second mounting block 11. The sliding seat 7 is fixed with the first mounting seat 12. The positioning plate 8 has a first rope 13 wound around the rope wheel 9. One end of the first rope 13 is fixed to the first mounting block 10 and the other end is fixed to the first mounting seat 12. The rear top plate 5 has a second rope 14 wound around the rope wheel 9. One end of the second rope 14 is fixed to the second mounting block 11 and the other end is fixed to the first mounting seat 12. Both the first rope 13 and the second rope 14 are made of steel wire rope.

[0018] In this embodiment, two rope wheels 9 are fixed on the side of the positioning plate 8, arranged vertically to keep the upper and lower sides of the first rope 13 horizontal. Two rope wheels 9 are fixed on the side of the rear top plate 5, arranged vertically to keep the upper and lower sides of the second rope 14 horizontal. At the same time, rope wheels 9 are fixed on both sides of the positioning plate 8 and the rear top plate 5, so that the first rope 13 and the second rope 14 can be installed on both sides of the positioning plate 8 and the rear top plate 5, ensuring the stability of the sliding seat 7 moving back and forth.

[0019] in, Figure 4 With the sliding seat 7 positioned at its extreme rearward extension point, when the telescopic end of the second telescopic mechanism 6 moves the middle cylinder 2 forward, the lower side of the first rope 13 extends and the upper side shortens, and the upper side of the second rope 14 extends and the lower side shortens, thus enabling the sliding seat 7 to slide forward relative to the middle cylinder 2. The distance it slides forward is the same as the distance the middle cylinder 2 retracts forward, thereby increasing the range of motion of the sliding seat 7 and ensuring the installation range of the drill rod 200.

[0020] refer to Figure 2 A clamping seat 15 is also fixed on the positioning plate 8 at the front end of the middle cylinder 2. The drill rod 200 passes through the through slot opened on the clamping seat 15. Two third telescopic mechanisms 16 are symmetrically arranged on the side of the clamping seat 15. The third telescopic mechanisms 16 can be cylinders. The telescopic ends of the two third telescopic mechanisms 16 face the drill rod 200. The two third telescopic mechanisms 16 are located on the side of the clamping seat 15 near the rear top plate 5, thereby ensuring the stability of the drill rod 200 when it moves.

[0021] refer to Figure 5The working arm also includes a telescopic cylinder 17. The sliding frame 1 is slidably disposed on the upper end of the telescopic cylinder 17. Specifically, two opposing limiting plates 172 are fixed on the upper end of the telescopic cylinder 17. A sliding plate 171 slides between the two limiting plates 172. The upper side of the sliding plate 171 is connected and fixed to the lower side of the sliding frame 1. A fourth telescopic mechanism 18 is hinged inside the telescopic cylinder 17. The fourth telescopic mechanism 18 is a hydraulic cylinder. The telescopic end of the front end of the fourth telescopic mechanism 18 is hinged to the lower end of the sliding frame 1.

[0022] Furthermore, a first fixed seat 19 is bolted to the lower side of the telescopic cylinder 17, and a pitch mechanism 20 is hinged to the lower side of the first fixed seat 19. The pitch mechanism 20 can be a hydraulic cylinder. The telescopic end of the pitch mechanism 20 is hinged to the front end of the telescopic cylinder 17. A vertical first rotation mechanism 21 is bolted to the lower side of the first fixed seat 19, and a horizontal second rotation mechanism 22 is bolted to the side of the first rotation mechanism 21. Both the first rotation mechanism 21 and the second rotation mechanism 22 can be rotary hydraulic cylinders. The pitch mechanism 20, the first rotation mechanism 21, and the second rotation mechanism adjust the alignment position of the front top plate 4, thereby adjusting it to different drilling positions.

[0023] refer to Figure 6 The working arm also includes a second mounting base 23 and a boom 24. A hinge rod 25 is fixed on the second mounting base 23. A first hinge seat 26 is hinged to the rear end of the boom 24. The first hinge seat 26 is rotatably connected to the hinge rod 25. A first swing seat 27 is welded and fixed to the side of the first hinge seat 26. A fifth telescopic mechanism 28 is hinged to the side of the second mounting base 23. The fifth telescopic mechanism 28 can be a hydraulic cylinder and is used to swing the boom 24. The telescopic end of the fifth telescopic mechanism 28 is hinged to the first swing seat 27. A sixth telescopic mechanism 29 is hinged to the lower side of the first hinge seat 26. The sixth telescopic mechanism 29 is a hydraulic cylinder and is used to raise and lower the front end of the boom 24.

[0024] refer to Figure 7 The front end of the boom 24 is bolted to a second hinge seat 30, and the output end of the sixth telescopic mechanism 29 is hinged to the lower side of the second hinge seat 30 (see reference). Figure 5 The second hinge seat 30 has a second swing seat 31 fixed to its side. The second swing seat 31 is hinged to the seventh telescopic mechanism 32, which can be a hydraulic cylinder. The front end of the second hinge seat 30 is hinged to the third hinge seat 33, and the output end of the seventh telescopic mechanism 32 is hinged to the third hinge seat 33.

[0025] In this embodiment, the third hinge seat 33 is welded and fixed to the end face of the second rotary mechanism 22, so that the second rotary mechanism 22 swings when the seventh telescopic mechanism 32 extends and retracts.

[0026] In use, this device adjusts the rock drilling equipment 100 to the drilling position via the sixth telescopic mechanism 29, the fifth telescopic mechanism 28, the seventh telescopic mechanism 32, the pitch mechanism 20, the first slewing mechanism 21, and the second slewing mechanism 22. Then, the first telescopic mechanism 3 and the second telescopic mechanism 6 are activated, and their front telescopic ends move the front top plate 4 forward. After the telescopic end of the first telescopic mechanism 3 reaches its telescopic limit, the distance between the front top plate 4 and the sliding frame 1 is fixed. At this time, the front top plate 4 presses firmly against the rock wall. Then, the front telescopic end of the second telescopic mechanism 6 moves forward again... The forward extension drives the middle cylinder 2 to slide backward out of the sliding frame 1. At this time, if the distance between the installation point of the drill rod 200 of the rock drilling equipment 100 and the front top plate 4 still does not meet the installation conditions of the drill rod 200, the telescopic end of the rear end of the second telescopic mechanism 6 extends backward. At this time, the lower side of the first rope 13 on the rope wheel 9 on the positioning plate 8 shortens and the upper side extends, and the upper side of the second rope 14 on the rope wheel 9 on the rear top plate 5 shortens and the lower side extends, realizing the sliding seat 7 sliding backward relative to the middle cylinder 2. When the middle cylinder 2 extends to the limit distance, the sliding seat 7 also moves to the rear end of the middle cylinder 2 (e.g., Figure 4 As shown), the installation range of the drill rod 200 is increased at this time. The drill rod 200 is installed on the rock drilling equipment 100, and the front end of the drill rod 200 passes through the front top plate 4. Then the rock drilling equipment 100 can be turned on to start drilling.

[0027] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
