Description
Technical Field
[0001] This utility model relates to the field of tunnel construction, and in particular to an auxiliary device for a rock drilling gun. Background Technology
[0002] Rock drills, as key equipment for drilling surrounding rock in tunnel construction, are widely used in scenarios such as drilling blasting holes, anchor bolt holes, and drainage and grouting holes. These devices are typically hand-operated and consist of a drive mechanism, an impact mechanism, and a drill bit assembly. They drill into the surrounding rock through high-frequency impact and are an indispensable tool in the initial stages of tunnel excavation. Most existing rock drills are portable, usually operated by a single person, offering a degree of mobility and operational flexibility. They can be quickly adjusted according to changes in the construction location, making them highly adaptable, especially suitable for small-scale drilling operations under complex geological conditions.
[0003] However, during long-term use, existing rock drilling equipment has revealed a series of technical defects. First, due to the equipment's considerable weight, typically exceeding 20kg, prolonged hand-held operation can easily lead to operator fatigue. Furthermore, the equipment operates with severe vibrations, generally exceeding 50Hz, which can cause musculoskeletal injuries and pose a significant occupational hazard. Second, the existing rock drilling gun structure does not adequately consider ergonomics, making it only suitable for vertical or slightly inclined operations. When working in special locations such as sidewalls or tunnel bottoms, the equipment struggles to provide stable support and cannot achieve horizontal drilling, easily leading to problems such as drill bit deviation and jamming, affecting construction quality and progress. Additionally, when the drilling position is below the operator's arm height, it is difficult to provide a stable and effective continuous thrust, especially in hard rock formations, easily resulting in low efficiency. Utility Model Content
[0004] In view of the above-mentioned defects of the existing technical solutions, the main purpose of this utility model is to develop a rock drilling gun auxiliary device, which can effectively solve the problems of difficult hand operation, limited posture and insufficient propulsion of existing rock drilling guns, and significantly improve construction efficiency and drilling quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rock drill auxiliary device includes:
[0007] The drive mechanism is used to move the rock drill along the drilling direction;
[0008] A housing for mounting the drive mechanism;
[0009] An inner support platform, mounted on the outer shell of the mechanism, is used to hold the rock drill.
[0010] An angle adjustment mechanism is located at the bottom of the outer casing of the mechanism and has a built-in spherical track;
[0011] The front support mechanism and the rear support mechanism are respectively connected to the bottom of the outer shell of the mechanism to support the overall equipment to form a triangular stable support structure;
[0012] The ball-head connector is slidably connected to the spherical track and connected to the front support mechanism to enable multi-angle and multi-directional adjustment of the rock drill.
[0013] The rear support hinge lug is located at the bottom center of the rear end of the housing of the mechanism and is hinged to the rear support mechanism via a detachable pin.
[0014] Preferably, it also includes lateral hinge ears symmetrically arranged on both sides of the bottom of the rear end of the housing. When the angle adjustment mechanism is adjusted to the lateral position, the lateral hinge ears are connected to the rear support mechanism through a detachable pin and are supported by the lateral hinge ears.
[0015] Preferably, it also includes an active mechanism and a driven mechanism, which are respectively fixed between the outer shell of the mechanism and the inner support platform by bolts. Under the action of the driving mechanism, the active mechanism and the driven mechanism provide continuous and stable propulsion power for the rock drill when it is working.
[0016] Preferably, the drive mechanism is a handwheel structure.
[0017] Preferably, the driving mechanism is a motor drive structure.
[0018] Preferably, both the front support mechanism and the rear support mechanism are telescopic structures, and the front support mechanism includes two support rods that can be adjusted in terms of opening and closing angle.
[0019] Preferably, the lateral hinge lug is located on the front side of the rear support hinge lug.
[0020] Preferably, the hinge axis of the rear support hinge lug is arranged perpendicular to the longitudinal centerline of the mechanism housing.
[0021] Preferably, the hinge axis of the transverse hinge ear is arranged parallel to the longitudinal centerline of the housing of the mechanism.
[0022] Preferably, the spherical track and the ball head connector work together to allow the rock drill to rotate 180° to the left or right.
[0023] The beneficial effects of this utility model are as follows: First, by setting up a front support mechanism, a rear support mechanism, and an inner support platform, this utility model forms a stable triangular support structure, which can firmly support the rock drill body and significantly reduce the reliance on manual hand-held operation. This structure not only improves the stability of the equipment during drilling but also effectively alleviates the risk of fatigue and injury to operators caused by the weight and vibration of the equipment, thus improving construction safety and ergonomic adaptability. Second, this utility model is equipped with an angle adjustment mechanism, which, through the cooperation of a spherical track and a ball head connector, realizes the multi-angle adjustment capability of the rock drill, allowing it to flexibly adapt to drilling needs in complex orientations such as the top, sidewalls, and bottom. Third, this utility model, through the drive mechanism combined with the active and driven mechanisms, provides stable propulsion force to the rock drill, enabling continuous output of effective thrust during drilling, which is particularly suitable for high-frequency impact operations in hard rock formations. In addition, this utility model reduces the direct contact time between operators and high-frequency vibrating equipment, reducing the probability of safety accidents caused by fatigue operation, improper posture, etc., while also reducing drilling deviation, stuck drill, and material waste caused by improper operation, thereby saving human resources and engineering costs while ensuring construction safety.

However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.
[0031] Please see Figure 1-3 This embodiment discloses a rock drill auxiliary device, including: a drive mechanism 1 for pushing the rock drill 2 to move along the drilling direction; the drive mechanism 1 can adopt a handwheel or motor drive structure, providing manual or automatic drive according to the operation requirements, ensuring continuous and stable propulsion force during drilling; a mechanism housing 3 for mounting the drive mechanism 1, the mechanism housing 3 forming the overall main frame of the device, and providing a mounting platform for each component and a force transmission path, ensuring the structural strength and overall stability of the device; an inner support platform 4, set on the mechanism housing 3, for placing the rock drill 2; the inner support platform 4 defining the installation position of the rock drill 2, and cooperating with the drive device for linear guidance and thrust transmission, improving the accuracy and consistency of drilling; and an angle adjustment mechanism 5, set at the bottom of the mechanism housing 3, with a built-in spherical track 6, the angle adjustment mechanism 5 connecting to the spherical track 6... The ball joint connector 9 forms a mating structure, allowing the rock drill 2 to adjust its posture in multiple spatial directions to adapt to different working surfaces. The front support mechanism 7 and the rear support mechanism 8 are respectively connected to the bottom of the housing 3 to support the overall equipment and form a triangular stable support structure. The ball joint connector 9 can be slidably connected in the spherical track 6 and connected to the front support mechanism 7 to realize multi-angle and multi-directional adjustment of the rock drill 2. The sliding connection of the ball joint connector 9 allows the equipment to quickly adjust the drilling direction and maintain the angle locked state after positioning to avoid deviation during drilling. The rear support hinge ear 10 is set in the middle of the bottom of the tail end of the housing 3 and is hinged to the rear support mechanism 8 through a detachable pin. The rear support hinge ear 10 provides the axial rotational freedom of the rear support mechanism 8, allowing it to swing and lock flexibly according to the adjustment angle, effectively enhancing the support reliability during lateral operations.
[0032] Furthermore, it also includes lateral hinge ears 11 symmetrically arranged on both sides of the bottom of the rear end of the housing 3. The lateral hinge ears 11 provide additional support points when the rock drill 2 is operating laterally. When the angle adjustment mechanism 5 is adjusted to the lateral position, the lateral hinge ears 11 are connected to the rear support mechanism 8 through a detachable pin, and the force is supported by the lateral hinge ears 11, thus forming an effective lateral support structure to prevent the equipment from shaking or shifting angle due to insufficient support during drilling on the side wall or bottom. In addition, it also includes an active mechanism 12 and a driven mechanism 13, which are respectively fixed between the housing 3 and the inner support platform 4 by bolts. The active mechanism 12 and the driven mechanism 13 constitute a push transmission assembly, which, together with the drive mechanism 1, forms a complete force transmission path. Under the action of the drive mechanism 1, the active mechanism 12 and the driven mechanism 13 provide continuous and stable propulsion power for the rock drill 2 during operation, ensuring the stability and accuracy of the thrust during drilling and adapting to the construction needs under different rock strength conditions.
[0033] In this embodiment, both the front support mechanism 7 and the rear support mechanism 8 are telescopic structures. These telescopic structures allow for flexible adjustment of the equipment's height and angle according to different construction positions, improving the adaptability of the rock drill 2 on different working surfaces and effectively enhancing support stability, thus reducing the risk of equipment overturning or shifting during construction. The front support mechanism 7 includes two support rods, whose opening and closing angles can be adjusted. The angle adjustment function of the two support rods, combined with the rotational capability of the ball joint connector 9, enables the entire equipment to have adaptive angle adjustment capabilities in both longitudinal and lateral directions. This facilitates rapid positioning and stable locking of the drilling angle, thereby improving the accuracy and operational convenience of multi-directional drilling.
[0034] Furthermore, the transverse hinge ear 11 is located in front of the rear support hinge ear 10. The transverse hinge ear 11 and the rear support hinge ear 10 are staggered at the rear end of the mechanism housing 3, allowing the equipment to be supported and connected by the appropriate hinge ear according to the operational requirements at different angles, thus improving the flexibility and applicability of the structure. The hinge axis of the rear support hinge ear 10 is arranged perpendicular to the longitudinal center line of the mechanism housing 3. The vertical setting of the hinge axis allows the rear support mechanism 8 to swing and adjust in the vertical direction, suitable for various drilling conditions. The hinge axis of the transverse hinge ear 11 is arranged parallel to the longitudinal center line of the mechanism housing 3. The parallel setting of the hinge axis is used to support the lateral rotation and positioning of the rock drill 2. When the angle adjustment mechanism 5 is adjusted to the lateral position, it can be supported by the transverse hinge ear 11, improving the stability and operability of the equipment during drilling.
[0035] In this embodiment, the spherical track 6 and the ball-head connector 9 cooperate to enable the rock drill 2 to rotate 180° to the left or right. The spherical track 6 is an arc-shaped trajectory structure embedded in the angle adjustment mechanism 5. The ball-head connector 9 is slidably embedded in the spherical track 6, forming a multi-degree-of-freedom rotational connection. Limiting or stopping structures can be set on the spherical track 6 to limit the rotational stroke of the rock drill 2 and ensure its stability when positioned at the target angle. At the same time, it prevents the ball-head connector 9 from accidentally disengaging from the spherical track 6 due to severe operational vibration or misoperation. This cooperative structure allows the rock drill 2 to rotate and adjust within a range of 180° to the left and right around the axis after being installed on the inner support platform 4, thereby adapting to drilling requirements of different orientations and angles. It is especially suitable for working scenarios on tunnel sidewalls or corners, improving the adjustability of drilling posture and positioning accuracy.
[0036] The operating steps of the rock drill auxiliary equipment in this implementation are as follows: First, determine the drilling position and angle to ensure that the drilling position is consistent with the target; based on the drilling position and angle, find the usage position of this equipment. The equipment should be placed close to the drilling target while meeting the requirements of stable support and propulsion space, so as to facilitate subsequent adjustments and operations; by adjusting the length of the front support mechanism 7 and the rear support mechanism 8, as well as the opening and closing angle of the two support rods in the front support mechanism 7, the initial adjustment of the equipment's operating height and angle is achieved; through the cooperation of the spherical track 6 built into the angle adjustment mechanism 5 and the ball head connector 9, the rock drill 2 can achieve a total 180° rotation adjustment in the left and right directions, thereby further aligning the rock drill 2 with the drilling target position and matching the required angle, ensuring the correct drilling posture. Connect the rear support mechanism 8 and the transverse hinge ear 11 with a pin, and adjust the length of the rear support mechanism 8. The transverse hinge ear 11 is located in front of the rear support hinge ear 10, providing stable transverse support when the rock drill 2 is in a lateral working state. At this time, fix the drilling angle that was adjusted in the previous steps to ensure that there is no attitude deviation during the drilling process. Start the rock drill 2, and use the drive mechanism 1 to apply a stable and continuous thrust to the rock drill 2 by manual or motor operation, pushing it to drill in the target direction until the predetermined drilling depth is reached. After drilling is completed, turn off the rock drill 2, and drive the rock drill 2 backward and gradually withdraw from the drilling by manually rotating the handwheel in the opposite direction or reversing the motor until the equipment is completely removed from the tunnel working face, completing the entire drilling operation process.
[0037] In summary, this utility model discloses a rock drill auxiliary device, including a drive mechanism 1, a mechanism housing 3, an inner support platform 4, an angle adjustment mechanism 5, a spherical track 6, a front support mechanism 7, a rear support mechanism 8, a ball-head connector 9, a rear support hinge ear 10, a transverse hinge ear 11, an active mechanism 12, and a driven mechanism 13. Through the cooperation of these components, the device achieves stable support, angle adjustment, and continuous propulsion of the rock drill 2. By constructing a triangular stable support structure, setting a rotatable adjustment mechanism, and integrating an active / driven propulsion mechanism, this device not only solves the problems of difficulty in manual handling, limited angle, and insufficient thrust of traditional rock drills, but also significantly improves the stability, flexibility, and efficiency of drilling operations. This utility model has a reasonable structure and is easy to operate, making it particularly suitable for the engineering needs of drilling in different orientations during tunnel construction. It has good safety and adaptability, and has significant engineering application value and industry promotion significance for promoting the mechanization and intelligent development of rock drilling equipment.
