Description

Technical Field

[0001] This utility model relates to the field of rock drill technology, specifically a support structure for a rock drill. Background Technology

[0002] In modern construction and operation environments, the requirements for the multi-functionality and adaptability of equipment are increasing. In particular, when performing operations such as rock drilling and concrete breaking, rock drills often need to be able to flexibly adjust their posture to adapt to different operating scenarios and complex environments.

[0003] According to a search, Chinese patent document CN213838615U discloses a lightweight handheld rock drill, including a body and a cylinder. At least two positioning screws parallel to the drill rod are symmetrically arranged on both sides of the body. Each positioning screw has a clamping block at its end. An adjustment mechanism for adjusting the extension length of each positioning screw is provided on the side of the body. A limiting mechanism that cooperates with the side wall of the body is provided at the end of each positioning screw away from the clamping block. This invention provides positioning screws parallel to the drill rod around the periphery of the body, serving as a force point for supporting the body around the borehole. This facilitates stability of the machine during handheld drilling, preventing slippage and displacement. Simultaneously, the adjustable extension length of each positioning screw adapts to different rock surfaces, offering high flexibility and effectively reducing the labor intensity during drilling.

[0004] However, the above-mentioned technologies still have certain shortcomings. For example, the rock drill can only operate in a single direction by relying on the hydraulic cylinder, which cannot meet the multi-directional working requirements. Furthermore, manual adjustment of the direction is required, which not only brings inconvenience in adjustment but also shows a lack of flexibility. These shortcomings limit the application effect of the equipment in complex working environments. To address these issues, we provide a support structure for the rock drill. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a support structure for a rock drill.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support structure for a rock drill, including a chassis, a set of symmetrical support columns rotatably connected to the top of the chassis, and two support rods movably connected inside the two support columns, a mounting column fixedly connected to the top of the support column, and a set of symmetrical front-to-back limiting mechanisms respectively provided on the outer wall of the mounting column, limiting grooves with equal upper and lower intervals respectively opened on the outer wall of the support rod, and a support seat hinged to the top of the support rod, a rotary support mechanism rotatably provided inside the chassis, an electric push rod fixedly connected to the opposite side of the support column, and one end of the electric push rod hinged to the bottom end of the support seat, a pneumatic telescopic claw hinged to the bottom end of the support seat, and an organic body fixedly connected to the top of the support seat.

[0007] The aforementioned rotary support mechanism includes gear one, gear two, a rotating seat, and rotating rod one. Gear one meshes with gear two, and the top of gear one is fixedly connected to the bottom end of the rotating seat via a connecting shaft. The outer wall of rotating rod one is fixedly connected to the interior of gear two.

[0008] As mentioned above, the bottom ends of both gear one and gear two are rotatably connected to the inside of the chassis via a rotating shaft, and the top of the rotating seat is fixedly connected to the bottom ends of the two support columns respectively.

[0009] As described above, a servo motor is fixedly connected to the top of the rotating rod, and a support block is fixedly connected to the top of the chassis, with the top of the support block fixedly connected to the outer side of the servo motor.

[0010] The aforementioned limiting mechanism includes a locking block, a pressing rod, a spring, and a rotating rod II. One side of the locking block is fixedly connected to one end of the pressing rod, and the other end of the pressing rod is fixedly connected to one end of the spring. The outer wall of the rotating rod II is fixedly connected to the inside of the pressing rod.

[0011] As described above, the card block is adapted to the limiting groove, and the mounting block is fixedly connected to the outer wall of the mounting column.

[0012] As described above, both ends of the rotating rod are rotatably connected to the inside of the mounting block, and the end of the spring away from the pressing rod is fixedly connected to the outer wall of the mounting column.

[0013] Compared with existing technologies, the support structure of this rock drill has the following advantages:

[0014] I. This utility model, through its rotating support mechanism, enables the machine body to rotate horizontally. The controller activates the servo motor, which in turn drives gear two to rotate via rotating rod one. Gear two meshes with gear one, which in turn drives the support column on the rotating seat to rotate. This achieves horizontal rotation of the machine body on the support seat, allowing the machine body to flexibly adapt to various operating scenarios, meet the actual needs of complex environments, and improve operational flexibility and adaptability.

[0015] II. This utility model, through its limiting mechanism, allows for easy adjustment of the support height by simply pressing the pressing rod. This causes the spring to be compressed by the pressing rod, which rotates slightly on the rotating rod, causing the locking block to leave the limiting groove. At this point, the support rod can be moved to adjust the machine height. After adjustment, the spring's rebound force causes the locking block to re-enter the limiting groove, thus limiting the machine height. This simple pressing rod design makes operation extremely convenient; a light press is all it takes to quickly adjust the support height, greatly improving the ease of height adjustment.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] 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.

[0023] like Figure 1-4As shown, this utility model provides a technical solution: a support structure for a rock drill, including a chassis 1, a set of left-right symmetrical support columns 2 rotatably connected to the top of the chassis 1, and two support rods 3 movably connected inside the two support columns 2, a mounting column 4 fixedly connected to the top of the support column 2, and a set of front-back symmetrical limiting mechanisms 9 respectively provided on the outer wall of the mounting column 4, and limiting grooves 5 with equal upper and lower intervals respectively opened on the outer wall of the support rod 3, and a support seat 6 hinged to the top of the support rod 3, a rotary support mechanism 8 rotatably connected inside the chassis 1, an electric push rod 7 fixedly connected to the opposite side of the support column 2, and one end of the electric push rod 7 hinged to the bottom end of the support seat 6, a pneumatic telescopic claw 10 hinged to the bottom end of the support seat 6, and an organic body 11 fixedly connected to the top of the support seat 6.

[0024] First, when the vertical angle of the machine body 11 needs to be adjusted, the electric push rod 7 is activated by the controller. The electric push rod 7 then drives the support base 6 to rotate vertically, thereby causing the machine body 11 to rotate as well. This achieves precise adjustment of the angle of the machine body 11 to meet various operational needs and improve operational efficiency. Next, if the machine body 11 needs to be rotated horizontally, the servo motor 12 is activated by the controller. The servo motor 12 drives the rotary support mechanism 8 to rotate, causing the rotary support mechanism 8 to drive the machine body 11 on the support base 6 to rotate horizontally via the support column 2. This allows the machine body 11 to flexibly adapt to various operational scenarios and meet the actual needs of complex environments. Firstly, to improve the flexibility and adaptability of operation, secondly, when adjusting the height of the support base 6, simply press the limiting mechanism 9 to disengage it from the limiting groove 5. At this time, the support rod 3 can be moved to adjust the height of the machine body 11. After adjustment, the limiting mechanism 9 is re-entered into the limiting groove 5 to limit the height of the machine body 11. The height of the support base 6 can be quickly adjusted by simply pressing the limiting mechanism 9, greatly improving the convenience of height adjustment. Finally, after the angle or height of the machine body 11 is adjusted, the pneumatic telescopic claw 10 is activated by the controller to provide stable support for the support base 6, ensuring stability and safety during operation.

[0025] like Figure 1-2 As shown, the rotary support mechanism 8 includes a gear 801, a gear 802, a rotating seat 803, and a rotating rod 804. Gear 801 meshes with gear 802, and the top of gear 801 is fixedly connected to the bottom of the rotating seat 803 via a connecting shaft. The outer wall of the rotating rod 804 is fixedly connected to the inside of gear 802. The bottom ends of gear 801 and gear 802 are rotatably connected to the inside of the chassis 1 via a rotating shaft. The top of the rotating seat 803 is fixedly connected to the bottom ends of two support columns 2 respectively. A servo motor 12 is fixedly connected to the top of the rotating rod 804. A support block 13 is fixedly connected to the top of the chassis 1, and the top of the support block 13 is fixedly connected to the outside of the servo motor 12.

[0026] To rotate the machine body 11 horizontally, the servo motor 12 is started by the controller. The servo motor 12 drives the gear 2 802 to rotate through the rotating rod 804. The gear 2 802 meshes with the gear 1 801, and then drives the support column 2 on the rotating seat 803 to rotate through the gear 1 801. This achieves the horizontal rotation of the machine body 11 on the support seat 6, enabling the machine body 11 to flexibly adapt to various working scenarios, meet the actual needs in complex environments, and improve the flexibility and adaptability of the operation.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the limiting mechanism 9 includes a locking block 901, a pressing rod 902, a spring 903, and a rotating rod 904. One side of the locking block 901 is fixedly connected to one end of the pressing rod 902, and the other end of the pressing rod 902 is fixedly connected to one end of the spring 903. The outer wall of the rotating rod 904 is fixedly connected to the inside of the pressing rod 902. The locking block 901 is adapted to the limiting groove 5. The outer wall of the mounting post 4 is fixedly connected to the mounting block 14. Both ends of the rotating rod 904 are rotatably connected to the inside of the mounting block 14. The end of the spring 903 away from the pressing rod 902 is fixedly connected to the outer wall of the mounting post 4.

[0028] When adjusting the height of the support base 6, simply press the pressing rod 902, causing the spring 903 to be compressed by the pressing rod 902. The pressing rod 902 rotates slightly on the rotating rod 904, causing the locking block 901 to leave the limiting groove 5. At this time, the support rod 3 can be moved to adjust the height of the machine body 11. After the adjustment is completed, the rebound force of the spring 903 causes the locking block 901 to re-enter the limiting groove 5, thereby limiting the height of the machine body 11. This simple design of the pressing rod 902 makes the operation extremely convenient. The height of the support base 6 can be quickly adjusted by simply pressing it, greatly improving the convenience of height adjustment.

[0029] Working principle: First, when it is necessary to adjust the vertical angle of the machine body 11, the electric push rod 7 is activated by the controller. The electric push rod 7 then drives the support base 6 to rotate vertically, thereby driving the machine body 11 to rotate as well. This achieves precise adjustment of the angle of the machine body 11 to meet various operational needs and improve operational efficiency. Next, if it is necessary to rotate the machine body 11 horizontally, the servo motor 12 is activated by the controller. The servo motor 12 drives the gear 802 to rotate through the rotating rod 804. The gear 802 meshes with the gear 801, thereby driving the support column 2 on the rotating base 803 to rotate. This allows the machine body 11 on the support base 6 to rotate horizontally. Secondly, when adjusting the height of the support base 6, simply press the pressing rod 902, causing the spring 903 to be squeezed by the pressing rod 902. The pressing rod 902 rotates slightly on the rotating rod 904, causing the locking block 901 to leave the limiting groove 5. At this time, the support rod 3 can be moved to adjust the height of the machine body 11. After the adjustment is completed, the spring force of the spring 903 is used to make the locking block 901 re-enter the limiting groove 5, thereby limiting the height of the machine body 11. Finally, after the angle or height of the machine body 11 is adjusted, the pneumatic telescopic claw 10 is activated by the controller to make the pneumatic telescopic claw 10 provide stable support for the support base 6.
