High-standard railway engineering construction is an inevitable trend of development, and the use of traditional technology for construction can no longer meet the current high standard requirements for engineering.

[0003] During the construction and maintenance of existing railway tracks, a large amount of manual labor is required to perform segmented drilling and cleaning of residual debris inside the holes. Due to the length of the railway tracks, manual segmented drilling and cleaning wastes a lot of human resources and is inefficient and time-consuming, thus presenting certain limitations. Summary of the Invention

This device utilizes a sliding flatbed with a track structure at its upper end, allowing a drilling machine to design the drilling operation. After drilling, the drilling machine rises, and a rotating structure drives a purging device to clean the opening.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-3 The present invention provides a technical solution: an integrated mechanical installation device for a ballastless track transponder, comprising a track structure 1, a rotating structure 2, a telescopic device 3, a purging device 4, and a detection device 5;

[0025] The track structure 1 is fixedly installed on both ends of the upper surface of the plate 6. The track structure 1 includes a guide rail 11 and a sliding drill bit assembly 12. The sliding drill bit assembly 12 is slidably engaged with the guide rail 11. The guide rail 11 is provided with a locking device 13 for fixing the sliding drill bit assembly 12. A drilling machine 8 is fixedly connected to the outside of the sliding drill bit assembly 12.

[0026] The fixed end of the rotating structure 2 is connected to the track structure 1, and the output end of the rotating structure 2 is fixedly connected to the top of the purging device 4.

[0027] The fixed end of the telescopic device 3 is fixedly connected to the guide rail 11, and the output end of the telescopic device 3 faces the drilling direction;

[0028] The nozzle of the purging device 4 is directed toward the borehole area;

[0029] The detection device 5 is fixed to the lower sides of the flat plate 6 by the concave bracket 7, and the detection end of the detection device 5 is in close contact with the surface of the ballastless track slab.

[0030] In this embodiment, the flat plate 6 is made of high-strength alloy material and has electrically driven rollers that fit the railway rail. The guide rail 11 is a precision linear track, the length of which is customized according to the spacing requirements of the transponder mounting holes on the ballastless track. The sliding drill bit assembly 12 achieves high-precision sliding engagement with the guide rail 11 through a built-in slider, ensuring the straightness of the drilling machine 8 during movement. The locking device 13 adopts an eccentric wheel locking structure, which is easy to operate. When the sliding drill bit assembly 12 moves to the preset drilling position, the eccentric wheel handle can be turned to quickly lock and fix it, preventing displacement during drilling. The drilling machine 8 is a small pneumatic drilling machine with forward and reverse rotation functions. Its drill bit can be replaced according to the design diameter of the transponder mounting hole. The installation height of the drilling machine 8 can be finely adjusted by the adjusting bolt on the sliding drill bit assembly 12 to adapt to track slabs of different thicknesses or drilling requirements of different depths. After drilling is completed, the rotating structure 2 drives the blowing device 4 to rotate to directly above the drill hole. After blowing is completed, it rotates back to the initial standby position to avoid affecting the next operation of the drilling machine 8. The detection device 5 is used to detect the position of the reinforcing bars inside the ballastless track slab to avoid drilling into the reinforcing bars and damaging the drilling machine 8.

[0031] Specifically, the locking device 13 is an electromagnetic lock or a manual bolt lock. The control end of the locking device 13 is electrically connected to the equipment control system and can receive signals to automatically lock or unlock.

[0032] In this embodiment, an electromagnetic lock is preferred as the locking device 13 due to its fast response and stable, reliable locking force. When the slidable drill bit assembly 12 moves to the precise drilling position calculated by the equipment control system based on preset drilling parameters under the drive mechanism, the control system immediately sends a locking signal to the control terminal of the electromagnetic lock. The armature of the electromagnetic lock quickly engages under the action of electromagnetic force, firmly locking the slidable drill bit assembly 12 onto the guide rail 11, ensuring that it will not undergo any displacement due to vibration or external force during drilling, thereby guaranteeing the accuracy of the drilling position. When it is necessary to adjust the drilling position or after the drilling operation is completed, the equipment control system sends an unlocking signal, the electromagnetic lock is de-energized, and the armature springs open under the action of the return spring, allowing the slidable drill bit assembly 12 to move freely on the guide rail 11. In some application scenarios where the degree of automation is not high or cost factors are considered, a manual bolt lock can also be used as the locking device 13. After the operator moves the sliding drill bit assembly 12 into position, they tighten the bolts using a wrench or other tools, ensuring the bolt ends press firmly against the side of the guide rail 11 or the pre-set positioning hole, thus achieving mechanical locking. Unlocking is achieved by loosening the bolts in the opposite direction. Whether it's an electromagnetic lock or a manual bolt lock, the connection points with the sliding drill bit assembly 12 and the guide rail 11 are made of high-strength alloy material and precision-machined to ensure the stability of the lock and its long-term durability.

[0033] Specifically, the rotating structure 2 includes a fixed bracket 21 and a rotating motor 22, with the rotating motor 22 fixedly installed on one side of the fixed bracket 21.

[0034] In this embodiment, the fixed bracket 21 is constructed from high-strength aluminum alloy profiles with an L-shaped frame structure. Through precision casting and aging treatment processes, the bracket is ensured to have sufficient structural strength and rigidity, effectively bearing the weight of the rotary motor 22 and subsequent connecting components, and maintaining stability during rotation. The rotary motor 22 is a servo motor, which features fast response speed, high positioning accuracy, and stable output torque. Its model is selected according to the actual load and speed requirements of the equipment. For example, a servo motor with a rated power of 500W and a rated speed of 3000rpm can be selected. On the fixed bracket 21, a motor protective cover is also installed on the outside of the rotary motor 22. The protective cover is made of transparent acrylic sheet and is fixed to the fixed bracket 21 with bolts.

[0035] Specifically, the telescopic device 3 includes a slide rail 31 and a slide plate 32 disposed on the surface of the plate 6. The slide plate 32 and the slide rail 31 cooperate to slide together. A locking nut is threaded onto the slide plate 32 to fix the position of the slide plate 32.

[0036] In this embodiment, the slide rail 31 is a high-precision linear track made of 45# steel, with a surface hardness of HRC58-62 after quenching. The length of the slide rail 31 is set according to the maximum adjustment stroke required for transponder installation, for example, it can be set to 800mm. The slide rail 31 is fixed to the designated position on the plate 6 by countersunk bolts, and anti-loosening washers are also provided at the bolt connection to prevent loosening after long-term use. The sliding surface of the slide plate 32 that mates with the slide rail 31 is inlaid with a wear-resistant slider. The slider is made of polytetrafluoroethylene material, which has a low coefficient of friction and good wear resistance, ensuring that the slide plate 32 slides smoothly on the slide rail 31 and has a long service life. The upper surface of the slide plate 32 is machined with a T-slot for installing subsequent transponder clamping components. The locking nut is an M12 high-strength hexagonal nut, and its fit with the threaded hole on the slide plate 32 is 6H / 6g. When the slide plate 32 slides to the target position, tightening the locking nut will make the end face of the nut fit tightly against the side of the slide rail 31, and the slide plate 32 will be reliably fixed by friction. Limiting blocks are also provided at both ends of the slide rail 31. The limiting blocks are made of rubber and are glued to the ends of the slide rail 31 to effectively prevent the slide plate 32 from sliding excessively and detaching from the slide rail 31.

[0037] Specifically, the purging device 4 includes an air pump 41 and a purging tube head 42. The air pump 41 is connected to the purging tube head 42 through a pipe. The purging tube head 42 is fixedly connected to the output end of the rotary motor 22. The purging tube head 42 is also equipped with a position sensor.

[0038] In this embodiment, the air pump 41 is a miniature oil-free silent pump with a rated working pressure of 0.3-0.5 MPa and a maximum flow rate of 8 L / min, providing sufficient and stable airflow to meet purging requirements. The air pump 41 is equipped with an airflow regulating valve and is fixed to the upper side of the plate 6 via a shock-absorbing bracket. The shock-absorbing bracket uses a combination of springs and rubber pads to effectively reduce vibration and noise generated during operation. The pipe connecting the air pump 41 and the purging nozzle 42 is a high-pressure flexible PU hose with an inner diameter of 8 mm and an outer diameter of 12 mm, exhibiting good flexibility and aging resistance. The outer layer of the pipe is also wrapped with a nylon braided mesh to enhance its pressure resistance and prevent rupture under long-term high-pressure airflow. The purging nozzle 42 is precision-machined from brass, with four evenly distributed 120-degree angled jet nozzles at its end. Each jet nozzle has a diameter of 1.5 mm. This design allows the ejected airflow to form a conical purging area, ensuring comprehensive and thorough cleaning of the transponder mounting surface. The position sensor of the purge tube head 42 is a laser displacement sensor with a measurement accuracy of ±0.02mm and a measurement range of 50-300mm. It can monitor the distance between the purge tube head 42 and the transponder mounting surface in real time and feed the distance signal back to the equipment's control system. When the distance exceeds a set threshold (e.g., less than 30mm or greater than 50mm), the control system will automatically adjust the speed of the rotary motor 22 or the output pressure of the air pump 41 to ensure the best purging effect. The fixed connection between the purge tube head 42 and the output end of the rotary motor 22 adopts a keyway fit and set screw locking method. The keyway fit accuracy is H9 / h9, and the set screw is an M5 internal hexagon set screw made of high-strength alloy steel and hardened to ensure the stability of the connection and prevent loosening or eccentricity during rotation.

[0039] Specifically, the detection device 5 includes a rebar detection sensor 51, the signal output terminal of the rebar detection sensor 51 is connected to a signal processor, and the signal output terminal of the signal processor is connected to a prompting unit; when the rebar detection sensor 51 detects rebar at the drilling location, the prompting unit issues a prompt to the operator through an audible and visual signal.

[0040] Specifically, an RTK positioning device 7 is fixedly connected to one side of the upper end of the tablet 6 via a fixing rod, and a power supply box 9 is fixedly connected to the other side of the upper end of the tablet 6 via a fixing rod. The RTK positioning device 7 is located behind the power supply box 9.

[0041] In this embodiment, the power supply box 9 integrates a rechargeable lithium battery pack with a nominal voltage of 12V and a capacity of 20Ah, which can provide continuous and stable power support for all power-consuming units of the entire device, including the rotary motor 22, air pump 41, rebar detection sensor 51, signal processor, prompting unit, and RTK positioning device 7. The RTK positioning device 7 can position the entire device. Before operation, the position is input in advance so that the flat plate 6 can move according to the input position and drill holes after it is in place.

[0042] The working principle of this equipment is as follows: First, the equipment is placed stably on the ballastless track using the rollers under the flat plate 6, ensuring that the detection end of the detection device 5 is in close contact with the surface of the ballastless track slab. After starting the equipment, the detection device 5 begins to work, and the rebar detection sensor 51 scans the preset drilling area, transmitting the detected signal to the signal processor in real time. The signal processor analyzes and processes the received signal. If it determines that there is rebar below the drilling position, it immediately drives the prompting unit to issue an audible and visual alarm, reminding the operator to adjust the drilling position to avoid damaging the rebar or the drill bit of the drilling machine 8 during drilling. After confirming that the drilling position is safe, according to the design spacing and diameter of the transponder mounting holes, the sliding drill bit assembly 12 is moved along the guide rail 11 to the precise drilling position via the equipment control system or manually. At this time, if the locking device 13 is an electromagnetic lock, the control system sends a locking signal, and the electromagnetic lock armature engages to lock it; if it is a manual bolt lock, the operator manually tightens the bolt to complete the fixation. Subsequently, the drilling machine 8 is started and driven towards the track slab by the telescopic device 3 to perform the drilling operation. After drilling is completed, the drilling machine 8 is reset under the drive of the telescopic device 3. Next, the rotary motor 22 in the rotating structure 2 receives a control signal and drives the purging device 4 to rotate directly above the drill hole. At this time, the position sensor monitors the distance between the purging nozzle 42 and the mounting surface and feeds it back to the control system, ensuring that the air pump 41 is activated at the appropriate distance. High-pressure airflow passes through the angled jet nozzle of the purging nozzle 42 to thoroughly clean debris and dust inside and around the drill hole. After purging is completed, the air pump 41 stops working, and the rotary motor 22 drives the purging device 4 to rotate back to its initial standby position to avoid obstructing subsequent operations. If drilling of multiple holes is required, the above steps of moving, locking, drilling, and purging can be repeated. For the installation of the transponder, the position of the sliding plate 32 on the telescopic device 3 on the slide rail 31 can be adjusted to move the transponder clamping component to the mounting hole, completing the subsequent installation and fixing work. Throughout the process, the high-strength alloy material of the plate 6 ensures the overall rigidity of the equipment, the precision linear guide rail 11 and the high-precision sliding fit ensure the accuracy of the drilling position, and the coordinated work of each device realizes the integrated and efficient operation of drilling, cleaning and other processes during the installation of the ballastless track transponder.

[0043] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
