Description

Technical Field

[0001] This utility model relates to the field of drilling technology for anchoring holes on steep slopes, specifically a tower crane-type construction equipment for drilling anchoring holes on steep slopes. Background Technology

[0002] Currently, during the construction of railways and highways in mountainous areas of China, steep slopes are frequently encountered along the route. These steep slopes are prone to high-altitude landslides or rockfalls under natural conditions such as earthquakes and rainfall, posing significant safety hazards. Therefore, effective reinforcement of steep rock slopes in mountainous areas is necessary to prevent potential dangers. Various methods exist for supporting steep slopes, including anti-slide piles, retaining walls, anchor bolts, and anchor cables. Installing slope support devices requires drilling into the steep slope. Tower crane drilling rigs are commonly used in drilling operations, and these rigs typically use a basket to suspend the drilling machine in the hole. However, during drilling, the basket can sway, affecting the quality and dimensional accuracy of the borehole.

[0003] Chinese patent CN110552358A discloses a tower crane-type construction equipment for anchoring steep slopes. This equipment includes a suspended platform, dovetail guide rails, lifting lugs, an anchor hole drilling rig, fixing pins, an anchor hole identification device, a hook, a working wire rope, an electric hoist, a boom, an electric hoist limit sensor, a tower crane mounting base, a slewing mechanism, a winch tractor, a trailer, and a winch. The suspended platform has lifting lugs at its top. The dovetail guide rails are installed on the bottom plate of the platform, and the anchor hole drilling rig is installed on the bottom plate and cooperates with the dovetail guide rails, allowing it to move along the guide rails. Fixing pins are installed on the side of the platform facing the slope. The working wire rope connects the hook to the electric hoist, which is installed on the guide rails below the boom. This patent allows the suspended platform to accurately reach any construction position through the rotation of the boom and the operation of the electric hoist. Furthermore, using a winch as the power source for boom steering, while the slewing mechanism itself does not provide power, further simplifies the tower crane's structure and improves equipment reliability. On the ground, a winch tractor and trailer serve as the winch's installation platform.

[0004] However, this existing technology involves setting up two tractor units on the ground, each equipped with a winch. The bottom of the suspended platform is connected by steel cables, and four winches are used to pull down the four sides of the platform for stability. But this method has a problem: it's difficult to precisely control the synchronized rotation of the four winches. If the speed of one winch or the number of turns of its steel cable differs from the others, the suspended platform will struggle to remain stable. Utility Model Content

[0005] The purpose of this invention is to provide a tower crane-type construction equipment for anchoring boreholes on steep slopes. Anchor holes need to be pre-drilled at the bottom of the steep slope, and an expansion mechanism is installed on the suspended platform. During operation, the clamping plate on the expansion mechanism is first inserted into the bottom anchor hole, fitting tightly against the hole wall to secure the platform and prevent it from swaying during drilling. As drilling progresses, the expansion mechanism moves sequentially to the next completed anchor hole, ensuring the continuity of the drilling operation.

[0006] To address the existing technical problems, this utility model provides a tower crane-type construction equipment for anchoring drilling on steep slopes, including a tower crane body. A reciprocating mobile vehicle is mounted on the boom of the tower crane body. Winches are fixed on both sides of the mobile vehicle. A basket is suspended from the winches by steel wire ropes. A drilling machine for drilling holes on steep slopes is mounted on the basket and can reciprocate along the length of the basket. An anti-sway device for fixing the basket to the steep slope is provided on one side of the basket.

[0007] Preferably, the anti-sway device includes a moving mechanism and an adjusting mechanism disposed on the moving mechanism, wherein the adjusting mechanism is provided with an expansion mechanism for inserting into the slope anchoring hole.

[0008] Preferably, the expansion mechanism includes a movable clamping plate, which has a clamping position and a standby position. When the clamping plate is inserted into the slope anchoring hole, the clamping plate changes from the standby position to the clamping position, and the surface of the clamping plate contacts the inner wall of the slope anchoring hole.

[0009] Preferably, the expansion mechanism includes a support sleeve, and a plurality of rotatable first support rods are evenly arranged around the outside of the support sleeve. One end of the first support rod is movably connected to the inner wall of the clamping plate, and the other end of the first support rod is movably connected to the outer wall of the support sleeve.

[0010] Preferably, a telescopic drive component is fixed inside the support sleeve, and the output end of the telescopic drive component is connected to a movable disk. The expansion mechanism also includes a second support rod, one end of which is movably connected to the movable disk, and the other end of which is movably connected to the inner wall of the clamping plate. When the telescopic drive component extends, the clamping plate moves away from the support sleeve and contacts the inner wall of the slope anchoring hole. When the telescopic drive component retracts, the clamping plate moves towards the support sleeve and separates from the inner wall of the slope anchoring hole.

[0011] Preferably, the end of the movable disk is also equipped with a camera for identifying the location of the slope anchoring holes.

[0012] Preferably, the moving mechanism includes a fixed plate and a sliding plate disposed on the suspended platform. A lead screw is rotatably disposed at the center of the fixed plate along its length. The sliding plate is threaded onto the lead screw. A first rotary drive component is also fixed to one side of the fixed plate. The output end of the first rotary drive component is fixedly connected to one end of the lead screw.

[0013] Preferably, the adjustment mechanism includes a support block fixed on a slide plate in the moving mechanism, an adjustment member movably disposed on the support block, a second rotary drive member for rotating the adjustment member fixed on one side of the support block, and one side of the adjustment member fixedly connected to a support sleeve in the expansion mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the tower crane-type construction equipment for anchoring and drilling on steep slopes has a reasonable structure and the following advantages:

[0015] (1) This application requires pre-drilling slope anchoring holes on the slope and assembling an expansion mechanism on the suspended platform. When drilling is required, the suspended platform is moved to the pre-drilled slope anchoring hole position, at which point the expansion mechanism is inserted into the slope anchoring hole. Subsequently, the clamping plate moves and comes into close contact with the inner wall of the slope anchoring hole, thereby achieving stable fixation of the suspended platform and effectively preventing the platform from swaying during drilling. As drilling continues, the expansion mechanism will move sequentially to the next completed slope anchoring hole, ensuring the continuity of drilling operations.

[0016] (2) This application also includes an adjustment mechanism to adapt to slope changes at different locations on the slope. By operating the second rotary drive, the adjustment component can be driven to rotate, thereby changing the angle of the expansion mechanism so that it can flexibly adapt to slopes of various inclinations.

[0017] (3) This application is also equipped with a moving mechanism to deal with the situation that the distance between the slope anchoring holes may be different in actual drilling operations. By operating the first rotary drive, the lead screw can be driven to rotate, thereby realizing a small adjustment of the position of the expansion mechanism, ensuring that one end of the expansion mechanism can be smoothly and accurately inserted into the slope anchoring hole.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 As shown, this utility model provides a tower crane-type construction equipment for anchoring drilling on steep slopes, including a tower crane body 1, which serves as the main support and moving platform for the entire construction equipment. The tower crane body 1 has a strong lifting capacity and a stable foundation structure. A reciprocating mobile vehicle 2 is installed on the boom of the tower crane body 1. The mobile vehicle 2 can flexibly adjust its working position in the horizontal direction, greatly expanding the working range. Winches 3 are fixed on both sides of the mobile vehicle 2. A basket 4 is suspended from the winches 3 by steel wire ropes. The basket 4 is stably suspended by the winches 3 through high-strength steel wire ropes. The basket 4 serves as the main bearing platform for drilling operations. Its structural design fully considers the safety and ease of operation of the operators, ensuring stability and easy control during the drilling process. A drilling machine body 5 is installed on the basket 4, which can reciprocate along the length of the basket 4 for drilling on steep slopes. An anti-sway device 6 is installed on one side of the basket 4 to fix the basket 4 to the steep slope.

[0027] The anti-sway device 6 includes a moving mechanism 61 and an adjusting mechanism 62 mounted on the moving mechanism 61. The moving mechanism 61 allows the anti-sway device 6 to move flexibly along the edge of the suspended platform 4 to adapt to different working positions and slope shapes. The adjusting mechanism 62 is equipped with an expansion mechanism 63 for insertion into the slope anchoring holes. The tight connection between the expansion mechanism 63 and the slope anchoring holes further enhances the stability of the suspended platform 4.

[0028] The expansion mechanism 63 includes a movable clamping plate 635. The clamping plate 635 has two states: a clamping position and a standby position. When the clamping plate 635 is inserted into the slope anchoring hole, it changes from the standby position to the clamping position, and its surface contacts the inner wall of the slope anchoring hole. When in the standby position, the clamping plate 635 maintains a compact shape, making it easy to insert into the slope anchoring hole. After the clamping plate 635 is inserted into the slope anchoring hole, it changes from the standby position to the clamping position. In this state, the surface of the clamping plate 635 unfolds and makes tight contact with the inner wall of the slope anchoring hole, forming a secure fixing point.

[0029] The expansion mechanism 63 includes a support sleeve 631, and several sets of rotatable first support rods 634 are evenly arranged around the outside of the support sleeve 631. One end of the first support rod 634 is movably connected to the inner wall of the clamping plate 635, and the other end of the first support rod 634 is movably connected to the outer wall of the support sleeve 631.

[0030] The support sleeve 631 has a telescopic drive component 632 fixed inside. The output end of the telescopic drive component 632 is connected to a movable disk 633. The expansion mechanism 63 also includes a second support rod 636. One end of the second support rod 636 is movably connected to the movable disk 633, and the other end of the second support rod 636 is movably connected to the inner wall of the clamping plate 635. When the telescopic drive component 632 extends, the clamping plate 635 moves away from the support sleeve 631 and contacts the inner wall of the slope anchoring hole. When the telescopic drive component 632 retracts, the clamping plate 635 moves towards the support sleeve 631 and separates from the inner wall of the slope anchoring hole.

[0031] When the telescopic drive member 632 extends, it pushes the movable disk 633 forward. Since one end of the second support rod 636 is movably connected to the movable disk 633 and the other end is movably connected to the inner wall of the clamping plate 635, the forward movement of the movable disk 633 causes the second support rod 636 to move, which in turn pushes the clamping plate 635 away from the support sleeve 631, contacting the inner wall of the slope anchoring hole and generating a clamping force. Conversely, when the telescopic drive member 632 retracts, it pulls the movable disk 633 backward. At this time, the second support rod 636 moves accordingly, causing the clamping plate 635 to move closer to the support sleeve 631, separating the clamping plate 635 from the inner wall of the slope anchoring hole. This design allows the expansion mechanism 63 to be easily inserted into and removed from the slope anchoring hole, while ensuring it is firmly fixed inside the hole after insertion.

[0032] The end of the movable disk 633 is also equipped with a camera 7 for identifying the location of the slope anchoring holes. The camera 7 is used to identify the location of the slope anchoring holes. This design greatly improves construction efficiency because operators can accurately determine the location of the slope anchoring holes through the real-time image from the camera 7, thereby guiding the insertion and clamping operation of the expansion mechanism 63.

[0033] The moving mechanism 61 includes a fixed plate 611 and a sliding plate 614 mounted on the suspended platform 4. A lead screw 613 is rotatably mounted at the center of the fixed plate 611 along its length. The sliding plate 614 is threaded onto the lead screw 613. A first rotary drive member 612 is also fixed to one side of the fixed plate 611. The output end of the first rotary drive member 612 is fixedly connected to one end of the lead screw 613.

[0034] When the position of the anti-sway device 6 needs to be adjusted, the first rotary drive 612 is activated, driving the lead screw 613 to rotate. Since the slide plate 614 and the lead screw 613 are connected by a thread, the slide plate 614 will move along the length of the lead screw 613, thereby changing the position of the expansion mechanism 63.

[0035] The adjustment mechanism 62 includes a support block 621 fixed on a slide plate 614 in the moving mechanism 61. An adjustment member 622 is movably disposed on the support block 621. A second rotation drive member 623 for rotating the adjustment member 622 is fixed on one side of the support block 621. One side of the adjustment member 622 is fixedly connected to the support sleeve 631 in the expansion mechanism 63.

[0036] The second rotary drive 623 is activated, which drives the adjusting component 622 to rotate. The rotation of the adjusting component 622 will cause the support sleeve 631 and the entire expansion mechanism 63 to adjust their angles to adapt to different slopes.

[0037] Working Principle: In operation, two slope anchoring holes are first pre-drilled at the bottom of the slope. Then, through the coordinated action of the tower crane body 1's moving vehicle 2 and the winch 3, the suspended platform 4 is lowered to the working position. At this point, the camera 7 accurately identifies the specific location of the slope anchoring holes. Next, the first rotary drive 612 is activated, driving the lead screw 613 to rotate, which in turn moves the sliding plate 614, achieving initial adjustment of the position of the expansion mechanism 63. Subsequently, by rotating the second rotary drive 623, the adjusting component 622 is driven to rotate, thereby changing the tilt angle of the second rotary drive 623 and its connected expansion mechanism 63 to adapt to different slope inclinations. After angle adjustment, through slight movement of the suspended platform 4, one end of the expansion mechanism 63 is accurately inserted into the slope anchoring hole. At this point, the telescopic drive 632 is activated, driving the moving disc 633 forward, which in turn pushes the second support rod 636 and the clamping plate 635 closer to the inner wall of the slope anchoring hole until the clamping plate 635 is in close contact with the slope anchoring hole, thus achieving stable fixation of the suspended platform 4. After the suspended platform 4 is fixed, the drilling machine 5 begins drilling operations on the slope. Since the suspended platform 4 has been firmly fixed, there will be no shaking during the drilling process. As the drilling operation continues, when drilling is completed, the expansion mechanism 63 will automatically move to the next drilled slope anchoring hole, preparing for the next round of drilling operations, thereby achieving continuous and efficient drilling operations.

[0038] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
