Description

Technical Field

[0001] This invention belongs to the technical field of slope construction equipment, specifically relating to a self-propelled platform device for drilling anchor cables and bolts on slopes. Background Technology

[0002] In slope anchor drilling, a common practice is to use a winch and steel cables to pull the drilling equipment along the slope. However, this traditional traction method has significant drawbacks. First, on steep slopes, the pulled equipment acts like a giant pendulum, easily swaying uncontrollably laterally and rotating around its axis during movement. This not only makes it difficult to accurately position the equipment at the intended drilling location, severely impacting construction efficiency, but also poses a serious threat to operational safety. Second, when the equipment is in place and drilling begins, the enormous reaction force generated when the drill bit contacts the rock mass, along with the component of the equipment's own weight along the inclined slope, creates an overturning moment that can easily cause the drill rod to misalign, borehole deviation, or even a major safety accident such as the entire equipment tipping over. Therefore, existing technologies suffer from problems such as the tendency for winches to sway when pulling drilling equipment, resulting in inaccurate borehole positioning, and poor anti-overturning capability during drilling operations. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a self-propelled platform device for drilling slope anchor cables and bolts, which solves the problems in existing technologies where the winch pulls the drilling equipment and causes swaying, resulting in inaccurate drilling positioning, and poor anti-overturning ability during drilling operations.

[0004] The objective of this invention can be achieved through the following technical solutions: The self-propelled platform equipment for drilling anchor cables and bolts on slopes includes a base frame placed on the slope surface, and an anchor drilling mechanism is installed on the base frame; The base frame is connected to a first cable, which is used to pull the base frame to move along the slope. The base frame is equipped with wheels for rolling along the slope. A second cable is installed on the slope, with its two ends fixed to the top and bottom of the slope, respectively. The second cable is in a tensioned state. A guide groove is provided on the wheel, and the second cable slides through the guide groove; The second cable is pressed against the guide groove to apply a clamping force to the wheel towards the slope.

[0005] Furthermore, the wheel includes multiple rollers, at least one of which has an annular groove on its peripheral wall. The annular groove is placed coaxially with the corresponding roller, and the area of ​​the annular groove away from the slope side forms a guide groove.

[0006] Furthermore, the second cable is configured as multiple cables arranged in parallel; Multiple rollers are divided into multiple rows of roller groups that correspond one-to-one with the second cable. Each row of roller groups includes at least two rollers, and each roller has an annular groove. The second cable passes sequentially through the annular grooves on each roller in the same set of rollers on the side away from the slope.

[0007] Furthermore, the maximum width of the annular groove along the roller axis is equal to the diameter of the second cable.

[0008] Furthermore, the wheel section also includes support bars, the number of which is equal to and corresponds one-to-one with the rollers. The upper end of each support bar is rotatably connected to a first roller, and the lower end of each support bar is rotatably connected to a second roller. The first roller and the second roller are placed coaxially with the central axis of the roller. The first roller is fixedly connected to the base frame, and the roller is fixedly sleeved on the second roller of the corresponding support bar. Each support bar is equipped with a first hydraulic push rod. One end of the first hydraulic push rod is rotatably hinged to the corresponding support bar, and the other end of the first hydraulic push rod is rotatably hinged to the base frame. The rotation plane of the first hydraulic push rod is perpendicular to the central axis of the first roller.

[0009] Furthermore, the anchor drilling mechanism includes a guide rail connected to the base frame, a slide table slidably connected to the guide rail, a rotary motor fixedly installed on the slide table, the output shaft of the rotary motor being placed coaxially with the guide rail, and a drill rod placed coaxially connected to the output shaft of the rotary motor. A drive unit is installed on the guide rail. The drive unit is connected to the slide table and is used to drive the slide table to move closer to or away from the slope along the guide rail axis.

[0010] Furthermore, a rotating shaft coaxial with the roller is rotatably connected to the guide rail, and the rotating shaft is fixedly connected to the base frame; The base frame is equipped with a second hydraulic push rod, the two ends of which are respectively hinged to the guide rail and the base frame. The rotation plane of the second hydraulic push rod is perpendicular to the central axis of the rotating shaft.

[0011] The beneficial effects of this invention are: 1. By sliding the second cable through the guide groove of the wheel, the second cable effectively limits the wheel, which not only effectively improves the guidance during the movement of the base frame, but also effectively resists the equipment swing and shaking caused by the traction of the first cable; at the same time, by continuously applying a clamping force towards the slope surface to the wheel through the second cable, a stabilizing torque is formed to resist overturning, effectively preventing the equipment from tilting backward and overturning during construction on steep slopes; 2. If there are uneven parts on the slope, the second roller and corresponding rollers can be adjusted by extending and retracting the first hydraulic push rod. This allows the rollers to be actively adjusted to work on different slope conditions. By maintaining stable contact between all rollers and the slope, the stability of the equipment in complex terrain is significantly improved. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] like Figures 1 to 4 As shown, the self-propelled platform equipment for drilling anchor cables and bolts on slopes includes a base frame 100 placed on the 700-degree slope, and an anchor drilling mechanism 200 is installed on the base frame 100. A first cable 301 is connected to the base frame 100, and the first cable 301 is used to pull the base frame 100 to move along the slope 700. The base frame 100 is equipped with a wheel 400 for rolling along the slope 700. A second cable 500 is provided on the slope 700. The two ends of the second cable 500 are fixed to the top and bottom of the slope 700 respectively. The second cable 500 is in a tensioned state. A guide groove 600 is provided on the wheel part 400, and the second cable 500 slides through the guide groove 600; The second cable 500 is pressed against the guide groove 600 to apply a clamping force to the wheel part 400 toward the slope 700. It should be noted that the first cable 301 is used in conjunction with the winch 300. The winch 300 retracts the first cable 301 to achieve the pulling and moving of the base frame 100. The first cable 301, winch 300 and base frame 100 can be configured in two different ways, and can be selectively designed according to actual needs; Example 1: The winch 300 is fixedly installed on the base frame 100. One end of the first cable 301 is fixedly connected to the winding drum of the winch 300, and the other end of the first cable 301 is fixedly connected to the top of the slope 700. Example 2: The winch 300 is fixedly installed on the top of the slope 700. One end of the first cable 301 is fixedly connected to the winding drum of the winch 300, and the other end of the first cable 301 is fixedly connected to the base frame 100. In Embodiment 2, the winch 300 is positioned at the top of the slope 700, which reduces the weight that the first cable 301 needs to pull compared to Embodiment 1. This approach in Embodiment 2 helps to reduce the power requirements of the winch 300 and also reduces the load on the base frame 100. In Embodiment 1, the winch 300 is directly fixed to the base frame 100, eliminating the need to transport the winch 300 to the top of the slope 700, making equipment deployment more convenient.

[0016] Preferably, both the first cable 301 and the second cable 500 can be made of steel cable; Before construction, first, the wheel part 400 of the base frame 100 is pressed tightly against the slope 700, and then the second cable 500 is installed so that the second cable 500 passes through the guide groove 600 formed by the annular groove 4011 away from the slope 700, and the second cable 500 is tightened so that it applies a pressing force to the roller 401 toward the slope 700. During construction, the first cable 301 is wound up by the winch 300, which pulls the base frame 100 upward, thereby driving the base frame 100 and the anchor drilling mechanism 200 to move up the slope 700 for position adjustment. The wheel section 400 facilitates the movement of the base frame 100 along the slope 700 by its rolling motion. The second cable 500 slides through the guide groove 600 of the wheel section 400, effectively limiting the wheel section 400. This not only improves the guidance of the base frame 100 during movement but also effectively resists equipment swaying and shaking caused by the traction of the first cable 301. Simultaneously, the second cable 500 continuously applies a clamping force towards the slope 700 to the wheel section 400, forming a stabilizing torque to resist overturning, effectively preventing the equipment from tilting backward or overturning during construction on the steep slope 700.

[0017] The wheel portion 400 includes a plurality of rollers 401. At least one roller 401 has an annular groove 4011 on its peripheral wall. The annular groove 4011 is placed coaxially with the corresponding roller 401. The area of ​​the annular groove 4011 away from the inclined side of the slope 700 forms a guide groove 600. The annular groove 4011 effectively prevents the second cable 500 from separating from the wheel 400 or from sliding laterally during movement, ensuring that the second cable 500 always maintains a stable contact relationship with the wheel 400.

[0018] The second cable 500 is configured as multiple cables arranged in parallel; Multiple rollers 401 are divided into multiple rows of roller groups corresponding to the second cable 500. Each row of roller groups includes at least two rollers 401, and each roller 401 is provided with an annular groove 4011. The second cable 500 passes sequentially through the annular groove 4011 on each roller 401 in the same set of rollers, away from the slope 700. Preferably, the number of second cables 500 is two; The annular grooves 4011 on the multiple rollers 401 in each row of rollers form a continuous and stable linear support for the corresponding second cable 500.

[0019] The maximum width of the annular groove 4011 along the axis of the roller 401 is equal to the diameter of the second cable 500; in order to avoid relative sliding between the roller 401 and the second cable 500 along the axis of the roller 401.

[0020] The wheel part 400 also includes support bars 402. The number of support bars 402 is equal to that of the rollers 401 and they correspond one-to-one. The upper end of each support bar 402 is rotatably connected to a first roller 403, and the lower end of each support bar 402 is rotatably connected to a second roller 404. The first roller 403 and the second roller 404 are placed coaxially with the central axis of the roller 401. The first roller 403 is fixedly connected to the base frame 100, and the rollers 401 are fixedly sleeved on the second roller 404 corresponding to the support bar 402. Each support bar 402 is provided with a first hydraulic push rod 405. One end of the first hydraulic push rod 405 is rotatably hinged to the corresponding support bar 402, and the other end of the first hydraulic push rod 405 is rotatably hinged to the base frame 100. The rotation plane of the first hydraulic push rod 405 is perpendicular to the central axis of the first roller 403. When the base frame 100 moves to any drilling location, if there are uneven parts on the slope 700, the corresponding support bar 402 is driven to rotate around the first roller 403 by adjusting the extension and retraction of the first hydraulic push rod 405. This, in turn, drives the second roller 404 and the corresponding roller 401 to adjust their positions, allowing the roller 401 to be actively adjusted to use different slope 700 working conditions. By maintaining stable contact between all rollers 401 and the slope 700, the stability of the operation in complex terrain is significantly improved. Preferably, the wheel sets are arranged in two symmetrical rows, and the two support bars 402 corresponding to the two rollers 401 placed on the same axis in the two wheel sets share the same first roller 403; Preferably, both ends of the first hydraulic push rod 405 are rotatably connected to a first pin, and the two first pins are rotatably connected to the support bar 402 and the base frame 100 respectively, so as to realize the rotatable hinge connection between the first hydraulic push rod 405 and the support bar 402 and the base frame 100.

[0021] The anchor drilling mechanism 200 includes a guide rail 201 connected to the base frame 100, a slide table 202 slidably connected to the guide rail 201, a rotary motor 203 fixedly installed on the slide table 202, the output shaft of the rotary motor 203 and the guide rail 201 are placed in the same direction, and a drill rod 204 placed in the same direction is connected to the output shaft of the rotary motor 203. A drive unit is installed on the guide rail 201. The drive unit is connected to the slide table 202 and is used to drive the slide table 202 to move closer to or away from the slope 700 along the axial direction of the guide rail 201. Preferably, the detachable connection between the output end of the rotary motor 203 and the drill rod 204 can be any one of threaded locking connection or flange and quick-change chuck connection, so as to achieve coaxial detachable fixation of the two. Preferably, the drive unit can be a pneumatic cylinder or a hydraulic cylinder fixedly installed in the guide rail 201, and the output end of the pneumatic cylinder or hydraulic cylinder is fixed to the slide table 202; Preferably, a guide ring is installed on the guide rail 201, and the drill rod 204 slides through the guide ring. The guide ring is designed to improve the guidance of the drill rod 204 during the rotary drilling process.

[0022] A rotating shaft 205, which is placed coaxially with the roller 401, is rotatably connected to the guide rail 201. The rotating shaft 205 is fixedly connected to the base frame 100. The base frame 100 is provided with a second hydraulic push rod 206. The two ends of the second hydraulic push rod 206 are respectively rotatably hinged to the guide rail 201 and the base frame 100. The rotation plane of the second hydraulic push rod 206 is perpendicular to the central axis of the rotating shaft 205. By extending and retracting the second hydraulic push rod 206, the guide rail 201 is driven to rotate around the rotating shaft 205 to adjust the angle between the guide rail 201 and the base frame 100, thereby adjusting the angle between the drill rod 204 and the slope 700 to adapt to construction operations on slopes 700 with different inclination angles. Preferably, both ends of the second hydraulic push rod 206 are rotatably connected to second pins, and the two second pins are rotatably connected to the guide rail 201 and the base frame 100 respectively, so as to realize the rotational hinge between the second hydraulic push rod 206 and the guide rail 201 and the base frame 100; it should be noted that the two second pins and the rotating shaft 205 are arranged in a triangle to ensure that the second hydraulic push rod 206 can effectively adjust the tilt angle of the guide rail 201.
