Description

Technical Field

[0001] This utility model relates to the field of pneumatic anchor drilling machine technology, specifically a pneumatic anchor drilling machine for precise control of hole opening depth. Background Technology

[0002] As is well known, the pneumatic anchor drilling rig with precise hole depth control is an anchor support device used in mining roadways, tunnel support, slope reinforcement and other projects. It uses compressed air as power and can precisely control the drilling depth.

[0003] Existing pneumatic anchor drilling rigs with precise hole depth control have significant deficiencies in support and placement: when not in operation, these devices lack a dedicated support structure, making stable and orderly placement impossible. They can only be placed haphazardly on the ground or temporary platforms at the work site. This haphazard placement not only increases the risk of wear and tear due to direct contact with ground debris and dust, but also leads to disorderly stacking of equipment in the placement area, occupying work space and creating a messy work environment. This affects the efficiency of subsequent operations, makes it inconvenient to retrieve and manage the equipment, and is detrimental to ensuring standardized operations in mine roadway and tunnel support projects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pneumatic anchor drilling machine for precise control of hole opening depth.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic anchor drilling machine with precise control of drilling depth, comprising a body and a support mechanism. The support mechanism includes several components, each comprising a fixed plate, a support column, an electric push rod, a connecting block, a bearing, a cylinder, a connecting plate, and a locking block. The fixed plate is mounted on the body. One end of the cylinder is connected to the support column, and the other end of the cylinder passes through the fixed plate and connects to one end of the locking block. The connecting plate is fixedly connected to the fixed plate and has a slot. The other end of the locking block extends into the slot. One end of the electric push rod is connected to the fixed plate, and the other end of the electric push rod is connected to one end of the connecting block. The other end of the connecting block is connected to the support column via the bearing.

[0008] To facilitate operation of the equipment, the present invention is improved by providing a controller on the main body, the controller being electrically connected to the main body and the controller being electrically connected to the electric push rod.

[0009] To improve stability, this invention is improved by ensuring that the card block matches the card slot.

[0010] To improve stability, this utility model is improved by having several of the aforementioned support mechanisms arranged symmetrically.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a pneumatic anchor drilling machine with precise control of hole opening depth, which has the following beneficial effects:

[0015] This pneumatic anchor drilling rig with precise hole depth control solves the problem of existing equipment lacking a dedicated support structure and being placed haphazardly by setting up several symmetrically distributed support mechanisms. Utilizing the cooperation of support columns, electric push rods, and locking blocks and slots, it provides stable support for the equipment when not in operation, preventing direct contact with the ground and avoiding wear. It also prevents clutter in the placement area, ensuring a neat and orderly construction site. A handle with a rubber anti-slip layer is fixedly connected to the top of the main body, conforming to human grip habits. The anti-slip layer increases friction between the hand and the handle, ensuring stable grip even in wet or oily environments, facilitating equipment handling and drilling position adjustments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A pneumatic anchor drilling rig with precise control of drilling depth includes a body 1 and a support mechanism 2. The support mechanism 2 has several components, including a fixed plate 3, a support column 4, an electric push rod 5, a connecting block 6, a bearing 7, a cylinder 8, a connecting plate 9, and a locking block 10. The fixed plate 3 is mounted on the body 1. One end of the cylinder 8 is connected to the support column 4, and the other end of the cylinder 8 passes through the fixed plate 3 and is connected to one end of the locking block 10. The connecting plate 9 is fixedly connected to the fixed plate 3 and has a slot. The other end of the locking block 10 extends into the slot. One end of the electric push rod 5 is connected to the fixed plate 3, and the other end of the electric push rod 5 is connected to one end of the connecting block 6. The other end of the connecting block 6 is connected to the support column 4 through the bearing 7.

[0023] Working principle

[0024] After the equipment is placed in the designated work location, the support column 4 can directly contact the ground, providing initial support for the entire equipment and preventing the equipment from being placed randomly, which would result in a cluttered work area. The main body 1 is a conventional pneumatic anchor drilling machine with precise hole depth control on the market. Its core structure, including the power system, propulsion mechanism, and depth control module, is common knowledge to those skilled in the art and will not be described in detail here.

[0025] When it is necessary to start drilling operation on body 1, the operation procedure is as follows (in conjunction with...) Figure 1 (Structure shown):

[0026] Support unlocking operation: The operator activates the electric push rod 5 on the fixed plate 3. When the electric push rod 5 extends, it will drive the connecting block 6 connected to it to move synchronously. Since the connecting block 6 is movably connected to the support column 4 through the bearing 7, the movement of the connecting block 6 will directly push the support column 4 to move. During the movement of the support column 4, it will drive the cylinder 8 fixedly connected to it to move synchronously (the cylinder 8 is set through the fixed plate 3), thereby causing the locking block 10 at the other end of the cylinder 8 to disengage from the slot on the connecting plate 9. At this time, the support column 4 loses the limiting constraint of the slot and can rotate freely around the bearing 7, thus completing the support unlocking.

[0027] Operating procedure: After the support is unlocked, the operator can operate the main body 1 normally to carry out drilling operations. During operation, if the support column 4 is still in contact with the ground, as the main body 1 descends towards the working surface under the action of the propulsion mechanism, the support column 4 will passively rotate around the bearing 7 due to the reaction force of the ground. This rotation process will not hinder the descent stroke of the main body 1, ensuring that the main body 1 can descend stably to the set drilling depth. Special attention should be paid to the fact that the length of the cylinder 8 is designed with a safety margin. During the movement with the support column 4, it will never completely separate from the fixed plate 3, preventing the support column 4 from falling off the equipment and ensuring the safety of the operation.

[0028] Support reset operation: After the main body 1 completes the drilling operation, the operator needs to restore the equipment to its original position. Figure 1 The initial support state shown is a standard procedure for personnel in this field and will not be described in detail here. After resetting, the support column 4 can once again provide stable support for the equipment, preventing the main body 1 from directly contacting the ground and causing wear, while keeping the placement area clean and orderly.

[0029] To further enhance the ease of operation and automation of the equipment, in this embodiment, a controller 12 is integrated on the main body 1. This controller 12 is electrically connected to the core control system of the main body 1, allowing it to receive real-time operational status signals from the main body 1 (such as drilling start / stop commands and depth monitoring data). It is also electrically connected to the electric push rod 5 in the support mechanism 2, enabling it to directly send extension / retraction control commands to the electric push rod 5. This connection design eliminates the need for manual adjustment of the support structure; the controller 12 allows for simultaneous control of the drilling operation of the main body 1 and the unlocking and resetting of the support column 4, significantly simplifying the operation process and avoiding control delays or errors that may occur with manual operation, thus ensuring the overall coordination and stability of the equipment's operation.

[0030] To further enhance the stability of the support mechanism 2 during equipment support and unlocking, and to prevent support failure or operational jamming due to structural fit gaps, this embodiment incorporates an adaptive design for the core mating component of the support mechanism 2—the locking block 10 and the locking slot. This ensures that the locking block 10 and the locking slot are perfectly matched in size, shape, and assembly precision. When the equipment is in its initial support state, the locking block 10 can be tightly embedded in the locking slot, providing a stable limit for the support column 4 through precise surface-to-surface contact, preventing the support column 4 from shaking due to external forces or slight equipment displacement and causing unexpected movement. When the electric push rod 5 drives the support column 4 to move and unlock, the matching structural design also allows the locking block 10 to smoothly disengage from the locking slot, avoiding jamming due to dimensional deviations and ensuring the smoothness of the support and unlocking action. This provides crucial structural support for the overall stability of the equipment operation.

[0031] To further improve the overall stability of the pneumatic anchor drilling rig during the placement and operation of the support system and to avoid tilting and shaking of the equipment due to uneven support forces, in this embodiment, several support mechanisms 2 are symmetrically distributed along the outer periphery or bottom of the main body 1. The symmetrical layout allows the support force of each support mechanism 2 to be evenly distributed to different stress points of the main body 1, so that the overall force of the equipment is balanced. This prevents structural deformation of a single support mechanism 2 due to excessive load and also prevents the equipment from tipping over due to a shift in the center of gravity during placement. At the same time, when the main body 1 needs to adjust its position or bear the propulsion reaction force during drilling operations, the symmetrically arranged support mechanisms 2 can form a stable support frame, reduce the shaking amplitude of the equipment, provide a stable foundation for precise control of the drilling depth, and further ensure the safety and reliability of the equipment operation.

[0032] To further improve the ease of gripping and stability of the pneumatic anchor drilling rig during operation and to solve the problem of lack of suitable force application points when workers move or adjust the equipment position, in this embodiment, a handle 11 is fixedly installed at the top of the main body 1. The handle 11 is firmly fixed to the top of the main body 1 (such as welding, bolting, etc., to ensure that the connection strength meets the operational force requirements). The handle 11 is designed to fit the human hand gripping habits. When workers move the equipment, adjust the drilling position, or assist in stabilizing the main body 1 during operation, they can easily apply force by holding the handle 11, avoiding the inconvenience or accidental contact that may be caused by direct contact with other parts of the main body 1. At the same time, the fixed connection design can prevent the handle 11 from loosening or falling off during the force application process, providing a guarantee for convenient operation and safe use of the equipment.

[0033] To further improve the anti-slip performance of the pneumatic anchor drilling rig during precise control of drilling depth, and to prevent slippage caused by sweaty, oily hands or slight vibrations of the equipment when the operator holds the handle 11 to move the equipment or stabilize the main body 1, thus affecting operational safety and stability, an anti-slip layer is specially provided on the outer wall of the handle 11 in this embodiment. The anti-slip layer is tightly fixed to the outer wall of the handle 11 (such as by bonding or integral molding), ensuring that the anti-slip layer is not easy to fall off or lift after long-term gripping or contact with the external environment. At the same time, the anti-slip layer is made of rubber, which has good elasticity and coefficient of friction, and can closely conform to the skin of the hand, increasing the friction between the hand and the handle 11. Even in wet and oily working environments, it can provide a stable grip experience for the operator, further ensuring the safety and convenience of equipment operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
