Description

Technical Field

[0001] This application relates to the field of tunneling and anchoring equipment technology, and in particular to a mobile single-unit drilling rig anti-tipping device. Background Technology

[0002] In tunneling operations, anchor cables and bolts are required behind the working face, and drilling equipment often uses single-unit drilling rigs (such as pneumatic anchor bolt drilling rigs and hydraulic anchor bolt drilling rigs). However, in the complex tunneling working face environment, single-unit drilling rigs are very heavy, difficult to transport, and unstable during drilling, resulting in low transport and drilling efficiency. Moreover, during drilling operations, when workers hold the single-unit drilling rig, the machine body is unstable, posing risks such as tipping over and drill rod breakage, which not only affects the drilling quality and efficiency but also poses significant personal safety hazards to the workers.

[0003] Therefore, there is an urgent need to provide a technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0013] Preferably, the anti-tipping ring has a fan-shaped groove at its lateral opening, and correspondingly, the anti-tilt buckle has a fan-shaped buckle at each end that is adapted to the fan-shaped groove.

[0014] Preferably, one end of the anti-tilt buckle is rotatably connected to one end of the lateral opening of the anti-tipping ring via a pin, and the other end of the anti-tilt buckle is connected to the other end of the lateral opening of the anti-tipping ring via a pin.

[0033] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0034] During tunneling operations, the main method currently involves workers transferring and moving individual drilling rigs (hydraulic or pneumatic anchor drilling rigs). However, because workers manually operate the individual drilling rigs, the rigs become unstable, resulting in extremely low drilling efficiency. Furthermore, when workers manually operate the individual drilling rigs, they are prone to tipping over and causing drill rods to break, all of which pose significant personal safety hazards to the workers.

[0035] Based on this, this application provides a movable single-unit drilling rig anti-tipping device for fixing the single-unit drilling rig, reducing the degree of manual intervention during site relocation and operation, and preventing the single-unit drilling rig from tipping over during site relocation and operation. Figures 1 to 8As shown, the anti-tipping device includes a movable base 100 and an anti-tipping bracket 200 arranged on the movable base 100. The movable base 100 drives the single drilling rig 300 placed on the movable base 100 to move to another location and increases the stability of the single drilling rig 300 during operation. The anti-tipping bracket 200 limits the single drilling rig 300 on the movable base 100 to prevent it from tipping over during relocation and operation, thereby improving drilling quality.

[0036] A pair of support legs 103 arranged side-by-side and a pair of casters arranged side-by-side are provided on the bottom surface of the mobile base 100. Specifically, the mobile base 100 includes a base plate 101 and a reinforcing frame 102. The bottom surface of the base plate 101 is welded to the reinforcing frame 102, which is made of angle iron. A pair of support legs 103 and a pair of casters are installed at the four corners of the reinforcing frame 102, that is, two support legs 103 and two casters are respectively installed at the four corners of the reinforcing frame 102, and the two support legs 103 and two casters are arranged on the same side. Furthermore, the movement of the single drilling rig 300 is achieved by moving the single drilling rig 300 through the pair of casters arranged side-by-side, effectively improving drilling efficiency. At the same time, during operation, the pair of support legs 103 arranged side-by-side limit the movement of the mobile base 100, effectively enhancing the sliding limit of the single drilling rig 300 along the horizontal plane during operation, increasing the stability of the single drilling rig 300 during operation, and further improving the quality of group drilling.

[0037] In a specific example, the casters are made of plastic to ensure sufficient wear resistance and pressure resistance, and the caster surface is painted for corrosion protection to adapt to the humid and corrosive environment of coal mines. Moving handrails are welded onto the movable base 100 to facilitate gripping and applying force by workers. The moving handrails can be made of welded steel pipes to reduce costs while ensuring strength.

[0038] An anti-tipping bracket 200 is installed on the top surface of the base plate 101 of the movable base 100. Specifically, the lower end of the stabilizing support rod 201 is fixed (welded) to the top surface of the base plate 101 of the movable base 100. It should be noted that the stabilizing support rod 201 is fixed at an angle, that is, the angle between the stabilizing support rod 201 and the top surface of the base plate 101 is an acute angle. The upper end of the stabilizing support rod 201 is connected (welded) to the bottom surface of the anti-tipping assembly 202. The anti-tipping assembly 202 is supported and fixed by at least three stabilizing support rods 201 evenly distributed along the circumference of the anti-tipping assembly 202.

[0039] The anti-tipping component 202, with its annular structure, surrounds the outer wall of the transmission part of the single drilling rig 300 in a circumferential direction, limiting the drilling process and preventing the single drilling rig 300 from tipping over during site transfer and operation. A rubber buffer pad is installed between the anti-tipping component 202 and the outer wall of the single drilling rig 300 to effectively prevent rigid collisions and frictional wear between them. Simultaneously, the rubber buffer pad enhances the compressive force between the annular structure of the anti-tipping component 202 and the outer wall of the single drilling rig 300, further improving the stability of the single drilling rig 300 and enhancing drilling quality.

[0040] In a specific example, the anti-tipping assembly 202 includes an anti-tipping ring 212 with a side opening and an anti-tilt buckle 222 adapted to the anti-tipping ring 212. The anti-tipping ring 212 is fixedly installed on the top of at least three stabilizing supports 201. The anti-tilt buckle 222 is used to close the side opening of the anti-tipping ring 212, forming a ring structure with the anti-tipping ring 212 to encircle the single drilling rig 300. During the placement of the single drilling rig 300, the single drilling rig 300 is inserted into the anti-tipping ring 212 through the side opening, or the head of the single drilling rig 300 is inserted into the anti-tipping ring 212 from below. Then, the anti-tilt buckle 222 is installed in the side opening of the anti-tipping ring 212 to encircle the outer wall of the single drilling rig 300.

[0041] Specifically, the anti-tipping ring 212 has a C-shaped structure, and a fan-shaped groove 232 is provided at the C-shaped opening of the anti-tipping ring 212. Correspondingly, the anti-tilt buckle 222 has fan-shaped buckles 252 at both ends that are adapted to the fan-shaped groove 232. When the anti-tilt buckle 222 is installed, the fan-shaped buckles 252 are engaged in the fan-shaped groove 232, thereby closing the C-shaped opening of the anti-tipping ring 212.

[0042] In another specific example, one end of the anti-tilt buckle 222 is rotatably connected to one end of the lateral opening of the anti-tipping ring 212 by a pin, and the other end of the anti-tilt buckle 222 is connected to the other end of the lateral opening of the anti-tipping ring 212 by a pin. In other words, a first through hole 242 is provided vertically at the fan-shaped slot 232 on one side of the C-shaped opening of the anti-tilt ring 212, and a second through hole adapted to the first through hole 242 is also provided at the fan-shaped buckle 252 of the anti-tilt buckle 222. By rotating the pin through the first through hole 242 and the second through hole, the anti-tilt buckle 222 is rotatably connected to the anti-tilt ring 212. Similarly, by passing the pin through the first through hole 242 on the fan-shaped slot 232 on the other side of the C-shaped opening and the second through hole of the fan-shaped buckle 252 at the other end of the anti-tilt buckle 222, the anti-tilt buckle 222 can be connected to the anti-tilt ring to form a ring structure, which can be used to wrap around and fix the outer wall of the single drilling rig 300.

[0043] In this application, the upper part of the single drilling rig 300 is supported and fixed by the anti-tipping component 202, and the lower end of the single drilling rig 300 rests on the movable base 100. Specifically, the lower end of the single drilling rig 300 rests on the movable base 100 via a rotating base 500. The rotating base 500 is rotatably mounted on the movable base 100, and its top surface is provided with a settling groove 501 that matches the lower end of the single drilling rig 300. An end buffer pad 600 is also provided between the bottom surface of the settling groove 501 and the lower end surface of the single drilling rig 300, and an annular buffer wear-resistant pad 700 is also provided between the side wall of the settling groove 501 and the outer side wall of the single drilling rig 300. Thus, the end buffer pad 600 and the annular buffer wear-resistant pad 700 prevent rigid contact between the single drilling rig 300 and the rotating base 500, effectively reducing collisions and damage to the single drilling rig 300.

[0044] In a specific example, the rotating base 500 is rotatably mounted on the movable base 100 via a thrust bearing 400. Specifically, an upper rotating boss 104 is provided on the top surface of the movable base 100, and a stepped bearing hole 105 is provided on the upper rotating boss 104; correspondingly, a lower rotating boss is provided on the bottom surface of the rotating base 500, and a bearing countersunk hole 502 is provided on the lower rotating boss. The upper part of the thrust bearing 400 (thrust ball bearing) is installed in the bearing countersunk hole 502 of the rotating base 500, and the lower part of the thrust bearing 400 is installed in the stepped bearing hole 105 of the movable base 100, with a rotational clearance between the bottom surface of the lower rotating boss and the top surface of the upper rotating boss 104. Furthermore, after the single drilling rig 300 is placed on the rotating base 500, the single drilling rig 300 can make moderate relative movement in the circumferential direction through the thrust ball bearing, so as to avoid friction and wear caused by rigid contact between the single drilling rig 300 and the moving base 100.

[0045] In this application, at least three stabilizing struts 201 evenly distributed circumferentially along the anti-tipping component 202 are used to support and fix the anti-tipping component 202, thereby limiting the tilting of the single drilling rig 300, avoiding manual handling of the single drilling rig 300, effectively solving the problems of difficulty in relocating (transferring) the single drilling rig 300 and instability of the rig body during drilling, improving the stability of the single drilling rig 300, preventing the single drilling rig 300 from tipping over, reducing the risk of drill rod breakage, improving work efficiency, reducing the safety risks to operators, and allowing operators to focus their attention on the drilling rig 300. The system focuses on drilling quality and efficiency. The lower end of the single drilling rig 300 is placed on the mobile base 100 and moved by a pair of universal wheels arranged side by side on the same side, which realizes the relocation of the single drilling rig 300, improves the following efficiency of the anchor cables and anchor rods on the working face, effectively improves drilling efficiency, and ensures synchronous excavation and support on the working face. At the same time, during the operation, a pair of support legs 103 arranged side by side on the same side limit the movement of the mobile base 100, effectively enhances the sliding of the single drilling rig 300 along the horizontal plane during the operation, and further improves the quality of group drilling.
