Description

Technical Field

[0001] This utility model relates to the field of rail drilling technology, and in particular to a dual-positioning lithium-ion rail drilling machine with a protective structure. Background Technology

[0002] In modern railway construction, rail drilling is an essential project for roadbed, electrical communication and signaling construction. A rail drilling machine is a type of drilling machine used to drill holes in rails. A rail drilling machine consists of a power unit, a clamp, and a drilling unit. Its power unit can be an electric motor or a small gasoline engine.

[0003] Common dual-positioning lithium-ion rail drilling machines only include drilling functions and can drill holes in rails, but they lack protective features and cannot guarantee the safety of operators during drilling operations. This can easily lead to problems such as steel chips flying everywhere when drilling rails, and drill bits breaking and flying out. At this time, operators nearby may be hit by some of the flying steel chips or flying drill bits, affecting construction safety.

[0004] Therefore, given the lack of protective function in the aforementioned dual-positioning lithium-ion battery rail drilling machine, which is prone to dynamic dangers during drilling due to high-speed flying of steel chips and drill bit breakage, exposing surrounding operators to mechanical impact risks and seriously affecting construction safety and personnel protection, there is an urgent need to design a new type of dual-positioning lithium-ion battery rail drilling machine with a protective structure. Utility Model Content

[0005] To overcome the common problem of dual-positioning lithium-ion rail drilling machines lacking protective functions, which are prone to dynamic dangers during drilling due to high-speed flying of steel chips and drill bit breakage, causing surrounding operators to be exposed to mechanical impact risks, seriously affecting the construction safety factor and personnel protection.

[0006] The technical solution of this utility model is as follows: a dual-positioning lithium-ion rail drilling machine with a protective structure, comprising a support plate, a first C-shaped frame, a first cylinder, a connecting plate, a right connecting rod, a right protective plate, a left connecting rod, a left protective plate, a through slot, and a through hole. A through hole is provided through the center of the top of the support plate. The first C-shaped frame is provided on the right side of the top of the support plate. The first cylinder is provided on the top of the first C-shaped frame. The output end of the bottom of the first cylinder passes through the first C-shaped frame and is connected to the connecting plate. A right connecting rod is provided on the right side of the connecting plate. A right protective plate is provided at the end of the right connecting rod away from the connecting plate. A left connecting rod is provided on the left side of the connecting plate. The end of the left connecting rod away from the connecting plate passes through the through hole and is connected to the left protective plate. Two through slots are symmetrically provided at the front and rear ends of the left side of the left protective plate.

[0007] Preferably, the connecting plate is driven downward by the first cylinder, which simultaneously moves the right and left connecting rods downward. The right and left connecting rods then move the right and left protective plates downward until the through slot on the left protective plate aligns with the drill bit. When the drill bit passes through the through slot to drill into the rail, the right and left protective plates block the flying steel chips. Furthermore, the left protective plate blocks the drill bit if it breaks, thus providing protection. This addresses the common problem of dual-positioning lithium-ion rail drilling machines, which only have drilling capabilities but lack protective features. These machines cannot guarantee the safety of operators during drilling operations, and steel chips can easily fly everywhere when drilling into the rail, or the drill bit can fly out after breaking. In such cases, operators nearby may be hit by some of the flying steel chips or the flying drill bit, affecting construction safety.

[0008] Preferably, a right side plate is provided on the right side of the top of the support plate corresponding to the position of the first C-shaped frame, and a left side plate is provided on the right side of the top of the support plate corresponding to the position of the through hole. A motor is provided in the middle of the right side of the right side plate, and the output end of the left side of the motor passes through the right side plate and is connected to a bidirectional lead screw. The left end of the bidirectional lead screw is rotatably connected to the right side of the left side plate.

[0009] Preferably, two drive plates are threadedly connected to the left and right sides of the bidirectional lead screw, and the bottom end of the drive plate passes through the support plate and is connected to an L-shaped clamp.

[0010] Preferably, two sliding grooves are symmetrically provided at the front and rear ends of the top left side of the support plate, and two second cylinders are symmetrically arranged at the front and rear ends of the top left side of the support plate corresponding to the positions of the sliding grooves. Two second C-shaped frames are arranged at the front and rear sides of the bottom of the support plate corresponding to the positions of the sliding grooves.

[0011] Preferably, a right sliding plate is provided on the right side of the top of the second C-shaped frame, and a left sliding plate is provided on the left side of the top of the second C-shaped frame. The top ends of the right and left sliding plates pass through the sliding groove and are located above the support plate. The output end on the right side of the second cylinder passes through the left sliding plate and is welded to the left side of the right sliding plate.

[0012] Preferably, a drilling rig is installed on the inner side of the second C-shaped frame, a right handle is installed in the middle of the top of the right side plate, and a left handle is installed in the middle of the top left side of the support plate corresponding to the position of the two second cylinders.

[0013] Preferably, a lithium battery box is located in the middle of the top left side of the support plate, corresponding to the position of the left handle, and a PLC controller is located in the middle of the top left side of the support plate, opposite the position of the lithium battery box.

[0014] The beneficial effects of this utility model are:

[0015] 1. The connecting plate is driven to move vertically downward by the first cylinder. The connecting plate moves vertically downward by synchronously pulling the right and left connecting rods. The right and left connecting rods are linked to the right and left protective plates to complete the coordinated downward displacement until the preset through slot of the left protective plate is precisely aligned with the axis of the drill bit. When the drill starts, its drill bit passes through the through slot to perform rail drilling. At this time, the right and left protective plates form a double-sided protective structure to spatially constrain the metal chips generated by high-speed cutting. At the same time, when the drill bit breaks, the left protective plate physically intercepts the fragments through the high-strength material properties, thereby realizing the dual safety barrier function of dynamic processing protection and sudden breakage protection.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: a dual-positioning lithium-ion rail drilling machine with a protective structure, including a support plate 1, a first C-shaped frame 2, a first cylinder 3, a connecting plate 4, a right connecting rod 5, a right protective plate 6, a left connecting rod 7, a left protective plate 8, a through slot 9, and a through hole 10. A through hole 10 is formed through the center of the top of the support plate 1. The first C-shaped frame 2 is located on the right side of the top of the support plate 1. The first cylinder 3 is located on the top of the first C-shaped frame 2. The output end of the first cylinder 3 passes through the first C-shaped frame 2 and connects to the connecting plate 4. A right connecting rod 5 is located on the right side of the connecting plate 4. A right protective plate 6 is located at the end of the right connecting rod 5 away from the connecting plate 4. A left connecting rod 7 is located on the left side of the connecting plate 4. The end of the left connecting rod 7 away from the connecting plate 4 passes through the through hole 10 and connects to the left protective plate 8. Two through slots 9 are symmetrically formed at the front and rear ends of the left side of the left protective plate 8. The piston rod output end of the first cylinder 3 drives the connecting plate 4 to perform axial displacement in the vertical direction, and the connecting plate 4 synchronously pulls the right C-shaped frame 6. Connecting rod 5 and left connecting rod 7 move downwards at the same speed. Right connecting rod 5 drives right protective plate 6 to move downwards, and left connecting rod 7 drives left protective plate 8 to move downwards until the pre-set through groove 9 on the surface of left protective plate 8 is precisely coaxially positioned with the main shaft axis of drilling rig 22. When the carbide drill bit of drilling rig 22 penetrates through groove 9 to cut and drill a hole in the rail, right protective plate 6 and left protective plate 8 form a two-way protective area through their high-strength alloy steel plate material, effectively constraining the path of hot steel chips generated during the cutting process. At the same time, when the drill bit breaks due to abnormal load, left protective plate 8 forms a mechanical interception barrier for the broken drill bit fragments through the limiting structure of its through groove 9, realizing dynamic protection closed-loop control of the entire drilling operation. This protection function combines the synchronous displacement characteristics of the multi-link mechanism with the impact resistance of the protective plate material to ensure that operators are protected from the impact of high-speed flying chips and broken parts, meeting the mandatory requirements of railway construction safety regulations for drilling equipment protection systems.

[0024] Please see Figures 2-5In this embodiment, a right side plate 11 is provided on the right side of the top of the support plate 1, corresponding to the position of the first C-shaped frame 2. A left side plate 12 is provided on the right side of the top of the support plate 1, corresponding to the position of the through hole 10. A motor 13 is provided in the middle of the right side of the right side plate 11. The output end of the left side of the motor 13 passes through the right side plate 11 and is connected to a bidirectional lead screw 14. The left end of the bidirectional lead screw 14 is rotatably connected to the right side of the left side plate 12. The motor 13 drives the bidirectional lead screw 14 to rotate. Two drive plates 15 are threadedly connected to the left and right sides of the bidirectional lead screw 14. The bottom end of the drive plate 15 passes through the support plate 1 and is connected to an L-shaped clamp 16. The bidirectional lead screw 14 drives two drive plates 15 to move closer together, and the two drive plates 15 simultaneously drive two L-shaped clamping plates 16 to move closer together until the rail is clamped by the cooperation of the two L-shaped clamping plates 16. Two sliding grooves 17 are symmetrically opened at the front and rear ends of the top left side of the support plate 1. Two second cylinders 18 are symmetrically arranged at the front and rear ends of the top left side of the support plate 1, corresponding to the sliding grooves 17. Two second C-shaped frames 19 are arranged at the front and rear sides of the support plate 1, corresponding to the sliding grooves 17. The right slide plate 20 is driven to move to the right by the second cylinders 18, and the right slide plate 20 drives the second C-shaped frames 19 to move towards the rail.

[0025] Please see Figures 1-5 In this embodiment, a right sliding plate 20 is provided on the right side of the top of the second C-shaped frame 19, and a left sliding plate 21 is provided on the left side of the top of the second C-shaped frame 19. The top ends of both the right sliding plate 20 and the left sliding plate 21 pass through the sliding groove 17 and are located above the support plate 1. The output end on the right side of the second cylinder 18 passes through the left sliding plate 21 and is welded to the left side of the right sliding plate 20. During the movement of the second C-shaped frame 19, both the right sliding plate 20 and the left sliding plate 21 slide inside the sliding groove 17. A drilling rig 22 is provided on the inner side of the second C-shaped frame 19, and a right handle is provided in the middle of the top of the right side plate 11. 23. A left handle 24 is provided at the middle of the top left side of the support plate 1, corresponding to the position of the two second cylinders 18. The drilling machine 22 drills holes in the rail. Personnel can lift and carry the entire device through the right handle 23 and the left handle 24. A lithium battery box 25 is provided at the middle of the top left side of the support plate 1, corresponding to the position of the left handle 24. A PLC controller 26 is provided at the middle of the top left side of the support plate 1, corresponding to the position of the lithium battery box 25. The battery in the lithium battery box 25 supplies power to each component, and the PLC controller 26 controls the start and stop of each component.

[0026] During operation, the entire device is lifted and placed on the rail using the right handle 23 and left handle 24. Then, the motor 13 drives the bidirectional lead screw 14 to rotate. The rotating lead screw 14 causes the two drive plates 15 to move closer together, and the two drive plates 15 simultaneously drive the two L-shaped clamping plates 16 to move closer together until the rail is clamped by the cooperation of the two L-shaped clamping plates 16. After the rail is clamped, the first cylinder 3 drives the connecting plate 4 to move downwards. The connecting plate 4 simultaneously drives the right connecting rod 5 and the left connecting rod 7 to move downwards. The right connecting rod 5 and the left connecting rod 7 simultaneously drive the right protective plate 6 and the left protective plate 7 to move downwards. Plate 8 moves downward until the through groove 9 on the left protective plate 8 aligns with the drill bit of the drill rig 22. Then, the right sliding plate 20 is driven to move to the right by the second cylinder 18. The right sliding plate 20 then drives the second convex frame 19 to move towards the rail. The second convex frame 19 drives the drill rig 22 to move towards the rail. When the drill bit of the drill rig 22 passes through the through groove 9, the drill rig 22 is started and drills a hole in the rail. During the drilling process, the right protective plate 6 and the left protective plate 8 block the flying steel chips. When the drill bit breaks, the left protective plate 8 blocks the breakage, thus achieving the protective function.

[0027] Through the above steps, the first cylinder 3 drives the connecting plate 4 to perform a vertical downward linear displacement. The connecting plate 4 synchronously links the right connecting rod 5 and the left connecting rod 7 to generate a downward compound motion, forcing the right protective plate 6 and the left protective plate 8 to move synchronously down along the guide rail until the preset through groove 9 of the left protective plate 8 is precisely aligned with the axis of the drill bit of the drilling machine 22. When the drill bit penetrates the through groove 9 to perform rail drilling, the right protective plate 6 and the left protective plate 8 construct a semi-enclosed protective barrier based on the characteristics of high-strength metal plates, which passively intercepts the high-speed flying steel chips. At the same time, in the event of a sudden drill bit breakage, the left protective plate 8 actively blocks the broken drill bit fragments through the rigid structure around the through groove 9. This constructs a multi-level safety protection system to solve the problem that common dual-positioning lithium battery rail drilling machines only have the function of drilling, which can drill rails, but lack the function of protection. This can easily expose operators to the risk area of ​​flying steel chips and drill bit breakage, affecting safety.
