Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] The lithium-ion battery-modified anchor drill described in this application is mainly used for drilling railway track bolts. By changing the structure of the power source and transmission mechanism, and by improving the structure of the transmission mechanism and the installation method of the drill bit, the performance of the railway track bolt drilling equipment can be greatly improved.

[0029] See Figure 1 and combined Figures 2-4 The lithium battery-powered anchor machine of this utility model has a main structure including a frame 1, on which a power source, drive equipment, transmission mechanism, power output mechanism and drill bit 6 are installed.

[0030] Specifically, the power source in this application includes a lithium battery 2. A high-performance lithium battery 2 is used as the power source. The charging and discharging of the lithium battery 2 group is controlled by an intelligent power management system, which can ensure the safe use and high-efficiency utilization of the battery. The normal operating temperature range is -40℃ to 45℃, which can adapt to the railway track maintenance needs in different environments.

[0031] The driving device is specifically a motor 3, and the power output mechanism is specifically a power output shaft 5. The motor 3 is connected to the motor output shaft 31, and the motor output shaft 31 and the power output shaft 5 are respectively connected to the gear transmission mechanism 4 to form an effective transmission of output power.

[0032] The transmission mechanism is a gear transmission mechanism 4, which includes a planetary gear transmission assembly 41. Through the structure of the planetary gear transmission assembly 41, a compact and efficient gear transmission system can be formed, converting the electrical energy of the lithium battery 2 into mechanical energy to achieve torque transmission and regulation. The gears are made of high-strength alloy materials and undergo precision machining and heat treatment to ensure transmission accuracy and durability.

[0033] The gear transmission mechanism 4 is installed inside the transmission housing 11. The power output shaft 5, which is connected to the gear transmission mechanism 4, extends out of the transmission housing 11 and is detachably connected to the drill bit 6. With this arrangement, the end of the power output shaft 5 can be replaced with a water drill bit 6 of different specifications for bolts, enabling the bolt drilling operation to be performed quickly and accurately.

[0034] The lithium battery 2 is installed on the frame 1 of the modified anchor machine to power the motor 3. The operation of the motor 3 drives the motor output shaft 31 to rotate. Combined with the connection between the motor output shaft 31 and the power output shaft 5 and the gear transmission mechanism 4, the motor output shaft 31 drives the gear transmission mechanism 4 to rotate, which in turn drives the power output shaft 5 to rotate.

[0035] From the perspective of power transmission output, specifically, the planetary gear 41 transmission assembly includes multiple planetary gears 41, and the motor output shaft 31 includes a gear shaft section 32 located at the end. The planetary gears 41 are disposed on the circumferential periphery of the gear shaft section 32 and mesh with the gear shaft section 32.

[0036] Furthermore, the planetary gear 41 transmission assembly also includes a planet carrier 42, with each planetary gear 41 mounted on the planet carrier 42 via a connecting shaft 43, and the power output shaft 5 connected to the planet carrier 42.

[0037] During the transmission process, the motor output shaft 31 is simultaneously meshed with multiple planetary gears 41, which enables the multiple planetary gears 41 to revolve around the motor output shaft 31 when the motor output shaft 31 rotates. The planetary gears 41 are mounted on the planet carrier 42 through the connecting shaft 43, which drives the planet carrier 42 to rotate during the revolution of the planetary gears 41. Furthermore, the connection between the power output shaft 5 and the planet carrier 42 enables the planet carrier 42 to drive the power output shaft 5 to rotate, thereby realizing the transmission output of the driving torque.

[0038] The planetary gear 41 transmission form can realize multi-speed ratio and high-efficiency transmission. It has a compact structure and uniform load distribution, which can meet the needs of different working conditions.

[0039] The planetary carrier 42 includes a transition post 44 located at the bottom, and the top end of the power output shaft 5 is connected to the transition post 44 to form a synchronous rotation structure. Preferably, in order to ensure the reliability of the transmission, the transition post 44 and the planetary carrier 42 are an integral structure. The transition post 44 includes a flat structure. Specifically, the transition post 44 includes a cylindrical base structure. By symmetrically arranging flat cut surfaces 45 on both sides of the cylindrical base structure, the flat structure of the transition post 44 can be formed.

[0040] From the connection angle between the power output shaft 5 and the adapter post 44, the power output shaft 5 includes a socket 51 located at the top. The inner groove surface of the socket 51 follows the contour shape of the adapter post 44, which can form a stable and reliable connection relationship.

[0041] The aforementioned flat connection offers advantages such as compact structure, space saving, stable and reliable torque transmission, uniform distribution of transmission stress, effective prevention of local overload, and high connection strength. Furthermore, it effectively limits relative displacement between shafts, reduces the accumulation of motion errors, and provides advantages such as convenient assembly and disassembly and easy maintenance.

[0042] From the connection angle between the drill bit 6 and the power output shaft 5, the drill bit 6 is specifically detachably connected to the power output shaft 5 through the sliding sleeve 7.

[0043] The power output shaft 5 includes a threaded portion 52 at the bottom, and the sliding sleeve 7 is threadedly connected to the threaded portion 52. By detachably connecting the drill bit 6 to the bottom of the sliding sleeve 7, the drill bit 6 can be replaced quickly and accurately, which greatly improves the work efficiency of railway track maintenance.

[0044] This application optimizes the mechanical transmission structure and provides a quick-release structure between the drill bit 6 and the power output shaft 5, thereby combining the characteristics of high-efficiency transmission and quick-release and quick-installation of the drill bit 6, effectively improving construction efficiency.

[0045] During normal use, the top of the sliding sleeve 7 and the threaded part 52 at the bottom of the power output shaft 5 are fixedly connected by a thread. In order to achieve a detachable connection between the drill bit 6 and the sliding sleeve 7, a locking sleeve 8 is provided at the bottom of the sliding sleeve 7, and a plug section 61 is provided at the top of the drill bit 6. The plug section 61 is locked in the locking sleeve 8.

[0046] See Figures 5-6 The locking sleeve 8 is specifically equipped with a retractable locking spring 81 and a locking steel ball 82 that can lock the drill bit 6 insertion section 61 in the radial direction.

[0047] Furthermore, a locking hole 62 is provided at the insertion section 61 of the drill bit 6, which can cooperate with the locking steel ball 82. The locking sleeve 8 includes a retaining ring 83 and a relief ring 84. The retaining ring 83 and the relief ring 84 can slide up and down relative to the power output shaft 5 with the locking sleeve 8. When the locking sleeve 8 is lifted, the relief ring 84 can provide radial outward relief space for the locking steel ball 82. When the locking sleeve 8 is pressed down, the retaining ring 83 can press the locking steel ball 82 radially inward to the locking hole 62 of the insertion section 61 of the drill bit 6.

[0048] Combination Figure 5In general, when the locking sleeve 8 is moved upward, the locking steel ball 82 corresponds to the position of the clearance ring 84. Adjusting the axial position of the drill bit 6 up and down allows the side wall of the drill bit 6 to retract the locking steel ball 82 outward to the clearance ring 84 while operating in the occupied space. In this relaxed fit state, the drill bit 6 can be disassembled and assembled.

[0049] Combination Figure 6 In the process of connecting the drill bit 6, when the locking sleeve 8 is moved downward after the drill bit 6 is inserted, the locking steel ball 82 corresponds to the position of the retaining ring 83, which can make the inner side wall of the retaining ring 83 press the locking steel ball 82 inward into the locking hole 62 of the drill bit 6 insertion section 61, thus keeping the drill bit 6 locked and fixed on the sliding sleeve 7.

[0050] The locking sleeve 8 in this invention can be a conventional locking steel ball 82 structure. The above structure and disassembly / assembly process clearly illustrate the disassembly / assembly relationship of the drill bit 6 on the sliding sleeve 7. The locking sleeve 8 enables quick disassembly / assembly of the drill bit 6 on the sliding sleeve 7, allowing for rapid and accurate replacement of the drill bit 6, thus enhancing the adaptability and scope of the lithium battery-powered anchor conversion machine.

[0051] The frame 1 of this utility model is also provided with a power frame 12, and the power frame 12 is provided with a battery slot 13. The lithium battery 2 can be plugged into and installed in the battery slot 13, which can ensure the stable installation of the lithium battery 2 on the frame 1.

[0052] For ease of operation, a handle 14 is provided on the top of the frame 1, and multiple control buttons 15 are provided on the handle 14. A control box 16 is provided on the side of the power frame 12. The control box 16 contains a control component for controlling the operation of the lithium battery-powered anchor machine. By electrically connecting the control buttons 15 to the control component, the normal operation and control of the lithium battery-powered anchor machine can be achieved.

[0053] Meanwhile, the lithium battery-powered anchor machine is also equipped with a digital display function. A display screen and indicator lights (not shown in the figure) are set on the top of the control box 16. By electrically connecting the display screen and indicator lights to the control components, the remaining power and operating status can be displayed in real time, combined with the electrical connection between the lithium battery 2 and the control components.

[0054] It should be further noted that the speed of motor 3 in this application is adjustable, and the drilling speed of the lithium battery-powered anchor machine can be adjusted in multiple gears to adapt to different working conditions and improve equipment operating efficiency.

[0055] The control components of the lithium battery-powered anchor conversion machine enable precise control and monitoring of its various functions. Operators can easily start and stop the equipment using the control buttons 15 on the handle 14.

[0056] The control component also has fault diagnosis and alarm functions. The display screen and indicator lights can detect and prompt abnormal conditions of the equipment in a timely manner to ensure the safety of operation. The control component is not a core improvement point in this application, and will not be described in detail here.

[0057] The lithium battery-powered anchor machine of this utility model uses lithium battery 2 as a power source to provide stable and reliable power for the anchor machine. Lithium battery 2 has a long service life and is easy to maintain. It eliminates the noise, pollution and usage limitations of traditional internal combustion engines and pneumatic devices, and is suitable for various railway track environments, tunnels and other special places.

[0058] The optimized mechanical transmission system and quick-release device enable the modified anchor machine to quickly and accurately change drill bits 6, greatly improving the efficiency of railway track maintenance. The transmission gears and sliding sleeves 7 are made of high-strength materials, reducing the frequency of replacement of vulnerable parts and lowering equipment maintenance costs.

[0059] The lightweight design and intelligent control system make it easy for operators to operate the anchor changer, reducing labor intensity and improving the safety and comfort of the operation.
