Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, specifically to a road surface inspection device for railway engineering. Background Technology

[0002] With the development of the railway industry, the requirements for the safety and reliability of railway lines are becoming increasingly stringent. As the foundation of railway transportation, the condition of railway tracks directly affects the safety and efficiency of railway transport. Therefore, precise inspection of railway track surfaces is necessary to ensure the safe operation of the railway.

[0003] In railway construction, compacted road surfaces need to be tested to determine their compaction degree and whether the railway subgrade meets construction requirements. Traditional ring sampler sampling requires embedding a ring sampler into the road surface, then using excavation tools to remove the soil to be tested from inside the ring sampler. This process, involving repeated steps to collect samples at different depths, is inefficient. This paper proposes a road surface inspection device for railway engineering to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road surface inspection device for railway engineering, which solves the problem of road surface inspection.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a road surface inspection device for railway engineering, including a mounting plate, a reinforcing rib fixedly connected to the bottom of the mounting plate, an inspection observation window opened in the middle of the lower surface of the mounting plate, an inspection device fixedly connected to the middle of the upper surface of the mounting plate, the inspection observation window being adapted to the inspection device, connecting rods fixedly connected to both sides of the reinforcing rib, and buffer moving devices fixedly connected to both ends of the connecting rods;

[0006] The testing device includes a mounting frame. A hydraulic pump is fixedly connected to the middle of the upper surface of the mounting frame. A hydraulic lifting rod is fixedly connected to the output end of the hydraulic pump. A connecting frame is fixedly connected to the bottom of the hydraulic lifting rod. A slot is formed in the middle of the lower surface of the connecting frame. A locking block is slidably connected to the inner wall of the slot. Spring latches are fixedly connected to both sides of the upper surface of the locking block. Positioning holes are formed on both sides of the upper surface of the connecting frame, and the positioning holes are adapted to the spring latches. A sampling ring knife is fixedly connected to the middle of the lower surface of the locking block. An observation window is formed at the front end of the sampling ring knife. Limiting rods are fixedly connected to both sides of the inner wall of the mounting frame, and the limiting rods are adapted to the connecting frame. A fixing seat is fixedly connected to the bottom of the inner wall of the mounting frame.

[0007] Preferably, the buffer moving device includes a fixed plate, and telescopic fixed rods are fixedly connected to both sides of the lower surface of the fixed plate.

[0012] This utility model provides a road surface inspection device for railway engineering. Compared with the prior art, it has the following advantages:

[0013] 1. The road surface inspection equipment used in this railway project employs a hydraulic pump-driven hydraulic lifting rod, along with a limit rod to vertically guide the connecting frame. This ensures that the sampling ring cutter cuts into the road surface vertically and at a uniform speed, preserving the original state of the sample, such as compaction and structural delamination, and resulting in more accurate inspection data. The observation window of the sampling ring cutter, in conjunction with the inspection observation window, allows for real-time observation of the sample filling status, facilitating operators to promptly determine whether the sampling is complete, reducing invalid sampling attempts, and improving inspection efficiency.

[0014] 2. The road surface inspection equipment used in this railway project effectively absorbs vibrations caused by road surface bumps by setting up a buffer movement device through a combination of springs, damping rods and telescopic fixing rods. This protects the internal components of the equipment and prevents the equipment from shifting during movement, ensuring the accuracy of the sampling position. The lighting solves the inspection problem in low-light environments such as tunnels and at night, expanding the applicable time and scenarios of the equipment. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a road surface inspection device for railway engineering, including a mounting plate 1, a reinforcing rib 2 fixedly connected to the bottom of the mounting plate 1, an inspection observation window 3 opened in the middle of the lower surface of the mounting plate 1, an inspection device 4 fixedly connected to the middle of the upper surface of the mounting plate 1, the inspection observation window 3 being adapted to the inspection device 4, and connecting rods 5 fixedly connected to both sides of the reinforcing rib 2, and buffer moving devices 6 fixedly connected to both ends of the connecting rods 5.

[0023] The testing device 4 includes a mounting frame 401. A hydraulic pump 402 is fixedly connected to the middle of the upper surface of the mounting frame 401. A hydraulic lifting rod 403 is fixedly connected to the output end of the hydraulic pump 402. A connecting frame 404 is fixedly connected to the bottom of the hydraulic lifting rod 403. A slot 409 is provided in the middle of the lower surface of the connecting frame 404. A locking block 410 is slidably connected to the inner wall of the slot 409. Spring latches 411 are fixedly connected to both sides of the upper surface of the locking block 410. Positioning holes 412 are provided on both sides of the upper surface of the connecting frame 404. The positioning holes 412 are adapted to the spring latches 411. A sampling ring knife 405 is fixedly connected to the middle of the lower surface of the locking block 410. An observation window 406 is provided at the front end of the sampling ring knife 405. Limiting rods 407 are fixedly connected to both sides of the inner wall of the mounting frame 401. The limiting rods 407 are adapted to the connecting frame 404. A fixing seat 408 is fixedly connected to the bottom of the inner wall of the mounting frame 401.

[0024] The mounting plate 1 serves as the foundation for the equipment. The reinforcing ribs 2 at the bottom increase structural strength, preventing deformation due to vibration during movement or inspection, and ensuring the relative stability of the inspection observation window 3 with the road surface. The inspection device 4 in the middle of the mounting plate 1 inspects the road surface through the inspection observation window 3 directly below. The inspection device 4 is fixed to the mounting plate 1 by the mounting frame 401. The core power comes from the hydraulic pump 402. When it is necessary to sample the road surface to test its compaction, the hydraulic pump 402 starts, driving the hydraulic lifting rod 403 to extend downwards, causing the connecting frame 404 and the sampling ring 405 at the bottom to move downwards synchronously. The limiting rod 407 restricts the movement trajectory of the connecting frame 404, ensuring the stability of the sampling ring 405. The sampling ring 405 cuts vertically into the road surface, avoiding sample deformation or sampling failure caused by tilting. After the sampling ring 405 cuts into the road surface, the sample filling status can be observed in real time through the observation window 406 at the front end to determine whether the sampling is complete. After sampling is completed, the hydraulic lifting rod 403 retracts, bringing the sampling ring 405 back to the initial position. The fixed base 408 can support the connecting frame 404 in the non-working state to prevent the parts from being suspended and deformed by force. The design of the slot 409 and the locking block 410 makes it easy to replace and remove the sampling ring 405. During installation, the locking block 410 is pushed into the slot 409. When it reaches the appropriate position, the spring locking button 411 automatically pushes out and locks into the positioning hole 412 for fixation. During disassembly, simply press the spring locking button 411.

[0025] like Figures 1 to 5 As shown, the buffer moving device 6 includes a fixed plate 601. Telescopic fixed rods 602 are fixedly connected to both sides of the lower surface of the fixed plate 601. A damping rod 603 is fixedly connected to the middle of the lower surface of the fixed plate 601. A spring 604 is sleeved on the outer surface of the damping rod 603. A moving wheel 605 is fixedly connected to the bottom of the damping rod 603. A workbench 7 is fixedly connected to one side of the upper surface of the mounting plate 1. A control panel 8 is fixedly connected to the upper surface of the workbench 7. A push handle 9 is fixedly connected to the top of the rear end of the workbench 7. Heat dissipation vents 10 are provided on both sides of the workbench 7. A support base 11 is fixedly connected to the other side of the upper surface of the mounting plate 1. A mounting base 12 is fixedly connected to the top of the support base 11. A lighting lamp 13 is fixedly connected to the middle of the upper surface of the mounting base 12.

[0026] The fixed plate 601, as the load-bearing component of the buffer moving device 6, is connected to the connecting rod 5 to transfer the weight of the main body of the equipment to the structure below. The telescopic fixed rods 602 are symmetrically distributed on both sides of the fixed plate 601, providing vertical limiting to prevent lateral swaying of the device and ensure moving stability. The damping rod 603 and the spring 604 form a buffer mechanism to prevent the loosening of equipment components or the displacement of the sampling mechanism caused by resonance. The workbench 7 provides an operating platform for the operator. The control panel 8 on its surface integrates the electrical control module of the equipment. The push handle 9 allows the operator to push the equipment to move. The heat dissipation vents 10 are opened on both sides of the workbench 7 to dissipate the heat generated by the control panel 8 and internal electrical components during operation, to prevent circuit failure caused by high temperature, and to ensure continuous and stable operation of the equipment. In environments with insufficient light, such as inside tunnels or at night, the lighting lamp 13 provides sufficient light source to ensure that the sample status can be clearly observed through the observation window 406 and the inspection observation window 3 during the sampling process. At the same time, it facilitates accurate operation by the operator through the control panel 8 and avoids misoperation caused by light problems.

[0027] During operation (or use), the operator first pushes the equipment using the push handle 9. The moving wheels 605 move the entire device on the railway surface. If the surface is uneven, the buffer moving device 6 is activated. The spring 604 absorbs the impact force generated by the bumps through elastic deformation. The damping rod 603 suppresses the reciprocating vibration of the spring 604. The telescopic fixing rod 602 assists in limiting the position to prevent the main body of the equipment from shifting or the parts from loosening due to vibration, ensuring that the equipment arrives at the inspection position smoothly. After positioning, the inspection device 4 is activated through the control panel 8 on the workbench 7. The hydraulic pump 402 drives the hydraulic lifting rod 403 to extend downward. The connecting frame 404 moves vertically downward along the limiting rod 407, driving the sampling ring cutter 405 to accurately cut into the road surface. The design of the slot 409 and the locking block 410 facilitates the replacement and removal of the ring cutter. During installation, the locking block 410 is pushed into the slot 409. When it reaches the appropriate position, the spring locking button 411 automatically pushes out and locks into the positioning hole 412 for fixation. During disassembly, the spring locking button 411 is pressed.

[0028] During the sampling process, the operator can observe the filling status of the road surface sample, such as subgrade soil and base material, in real time through the observation window 406 of the sampling ring cutter 405 and the inspection observation window 3 of the mounting plate 1 to determine whether the sampling is complete. After the sampling is completed, the hydraulic lifting rod 403 retracts. If the environment is not well lit, such as in a tunnel or at night, the lighting lamp 13 on the mounting base 12 is turned on to provide sufficient light source for sampling observation and operation.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
