[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, proposes a multifunctional dual-purpose inspection vehicle, including a support plate 1; a plurality of swing plates 2, which are swingably arranged on both sides of the support plate 1, and after the swing plates 2 swing, a storage space is formed between the plurality of swing plates 2 and the support plate 1; a wheel set 3 is rotatably arranged relative to the swing plate 2, and the wheel set 3 has a first abutment surface 31 and a second abutment surface 32, and the first abutment surface 31 and the second abutment surface 32 are used to support the inspection vehicle; a storage box 4 is arranged on the swing plate 2, and after the swing plate 2 swings, the storage box 4 is located in the storage space.

[0024] In this embodiment, the support plate 1 is used as the main support structure of the inspection vehicle. Suitable metal materials such as aluminum alloy are selected to ensure strength while reducing weight. Multiple swing plates 2 can be swingably installed on both sides of the support plate 1 through connecting parts such as pins. The swing plates 2 can be made of lightweight plastic or alloy thin plates for easy operation. For example, when the inspection vehicle needs to be stored, the swing plate 2 is manually swung toward the support plate 1 so that a semi-enclosed storage space is formed between the multiple swing plates 2 and the support plate 1. The wheel set 3 is rotatably installed relative to the swing plate 2 through bearings and other devices. The wheel set 3 can be combined with a rubber tire and a metal wheel hub. The first abutment surface 31 is designed to be a smooth cylindrical shape for easy rolling on a flat road surface; the second abutment surface 32 is used for track operation. The storage box 4 is fixed on the swing plate 2. When the swing plate 2 is swung into place, the storage box 4 is just located in the storage space. When the inspection vehicle is working, it can store tools, testing instruments and other necessary inspection items. When the inspection vehicle is not working, the swing plate 2 can be swung to store the inspection vehicle to reduce the occupied space.

[0025] The unique design of the swing plate 2 cleverly realizes the storage function of the inspection vehicle and reduces the storage space occupied. At the same time, the storage box 4 is combined with the swing plate 2 to facilitate the storage and organization of items and improve the inspection efficiency. The double abutment surface design of the wheel set 3 enables it to adapt to different operating scenarios, enhancing the versatility of the inspection vehicle.

[0026] Furthermore, the first abutment surface 31 is cylindrical and is used to support the inspection vehicle on the road surface. The second abutment surface 32 includes a horizontal section 321, a transition section 322 and a limit section 323. The two ends of the transition section 322 are connected to the horizontal section 321 and the limit section 323. The horizontal section 321 is used to support the inspection vehicle on the track. The limit section 323 is used to abut against the side of the track. The first abutment surface 31 is located on the second abutment surface 32 and is used to abut against the upper and outer sides of the track. The first abutment surface 31 is located on the side of the second abutment surface 32 away from the track.

[0027] In this embodiment, for the wheel set 3, the first abutment surface 31 adopts a rubber-wrapped cylindrical metal shaft to ensure stability and grip when driving on the road. The horizontal section 321 of the second abutment surface 32 is designed as a plane adapted to the upper surface of the track, and the material is selected from wear-resistant metal. The transition section 322 is an arc slope, and the limit section 323 fits tightly with the side of the track to prevent the inspection vehicle from sliding sideways when running on the track. When the inspection vehicle needs to be transferred from the road beside the railway to the track for inspection, the operator pushes the inspection vehicle so that the second abutment surface 32 of the wheel set 3 is aligned with the track, and the horizontal section 321 first contacts the upper surface of the track. As it is pushed, the limit section 323 gradually abuts against the side of the track to achieve precise positioning. This finely designed wheel set 3 structure enables the inspection vehicle to switch between two different working conditions, road surface and track, conveniently and safely, broadens the working range of the inspection vehicle, does not require additional transfer equipment, and reduces the inspection cost and time consumption.

[0028] Furthermore, it also includes a support shaft 5, which is rotatably set at the end of the swing plate 2 away from the support plate 1, and the wheel group 3 is rotatably set on the support shaft 5. After the support shaft 5 rotates, the wheel group 3 is located on the extension line of the support plate 1 or perpendicular to the support plate 1.

[0029] Furthermore, the support shaft 5 includes a support rod 51, and the wheel group 3 is rotatably set on the support rod 51; one end of the shaft rod 52 is detachably set on the support rod 51, and the other end is rotatably set on the swing plate 2; the first limit rod 53 is set on the shaft rod 52; the top rod 54 is slidably set relative to the swing plate 2, and the top rod 54 is used to abut or cancel the abutment with the first limit rod 53 after sliding.

[0030] In this embodiment, a support shaft 5 is installed at one end of the swing plate 2 away from the support plate 1, and the wheel set 3 is fixed to the support rod 51 of the support shaft 5 through a sleeve. The support rod 51 and the shaft rod 52 are threadedly connected to facilitate disassembly and replacement. When the inspection vehicle needs to be stored, the operator manually rotates the support shaft 5 to rotate the wheel set 3 to a direction perpendicular to the support plate 1. At this time, the overall width of the inspection vehicle is reduced, which is convenient for storage. Further, the inspection vehicle is turned upside down 180°. At this time, the first abutment surface 31 can still contact the road surface, which is convenient for moving the inspection vehicle when it is stored or not in use; and in the normal inspection preparation stage, the wheel set 3 is rotated to the extension line of the support plate 1 to ensure driving stability. The rotatable design of the support shaft 5 further optimizes the storage performance of the inspection vehicle, so that it can flexibly adjust its shape under different storage and use requirements, reduce space occupation, and do not affect the normal operation function of the inspection vehicle, thereby improving the practicality and adaptability of the equipment.

[0031] The support rod 51 is made of high-strength alloy steel to ensure that it can bear the weight of the wheel set 3. One end of the shaft rod 52 is fastened to the support rod 51 through a nut, and the other end is installed on the swing plate 2 through a bearing to achieve flexible rotation. The first limit rod 53 is welded to the other end of the shaft rod 52, and the top rod 54 is installed on the swing plate 2 to slide relatively. A rubber pad is set at the end of the top rod 54 to avoid hard collision with the first limit rod 53. For example, after the wheel set 3 is adjusted into place, the top rod 54 is pushed to make it tightly abut against the first limit rod 53, limit the rotation of the shaft rod 52, and ensure that the wheel set 3 is fixed; when the wheel set 3 needs to be rotated again, pull the top rod 54 to cancel the abutment. Through the cooperation of the top rod 54 and the first limit rod 53, the rotation of the support shaft 5 is accurately controlled, and the accidental rotation of the wheel set 3 during operation or storage is avoided, the stability and reliability of the inspection vehicle structure are improved, and the safety of the inspection operation is guaranteed.

[0032] Furthermore, it also includes an armrest 6, which is slidably set on the support plate 1, and has a first gripping portion 61 and a second gripping portion 62 at both ends. The first gripping portion 61 is used to abut against the upper side of the support plate 1, and the second gripping portion 62 is used to abut against the lower side of the support plate 1.

[0033] In this embodiment, the handrail 6 is made of aluminum alloy pipe, which is hollow inside to reduce weight. A slide groove is set at one end of the support plate 1, and the handrail 6 is inserted into the slide groove to achieve sliding installation. The first gripping portion 61 is convenient for the operator to hold when pushing the inspection vehicle forward; the second gripping portion 62 is used after the inspection vehicle is turned upside down 180 degrees. When the inspection vehicle needs to be lifted, the handrail 6 is slid downward, and the second gripping portion 62 is upward, which is convenient for exerting force to pull the inspection vehicle.

[0034] The sliding design of the armrest 6 meets the operator's grip requirements under different operating postures of the inspection vehicle. Whether it is pushing or carrying, the operator can find a comfortable and stable force point, which improves the operating convenience and ergonomic performance and reduces labor intensity.

[0035] Furthermore, it also includes a second limiting rod 71, which is slidably arranged on the swing plate 2. After the second limiting rod 71 slides, it abuts against or cancels the abutment with the wheel group 3; the sliding plate 72 is slidably arranged relative to the supporting plate 1, and the sliding plate 72 has a guiding inclined surface at one end close to the second limiting rod 71. After the sliding plate 72 slides, the guiding inclined surface is used to abut against the second limiting rod 71 and push the second limiting rod 71 to slide; the two ends of the first elastic member 73 act on the swing plate 2 and the second limiting rod 71 respectively, so as to provide a force for the second limiting rod 71 to move away from the wheel group 3; the ends of the wheel group 3 and the second limiting rod 71 that are close to each other are both provided with a chuck 74, and the chuck 74 has a plurality of limiting grooves 741 and limiting protrusions 742 distributed at intervals. After the second limiting rod 71 slides, the limiting protrusion 742 slides into the relative limiting groove 741.

[0036] In this embodiment, the second limiting rod 71 is installed on the swing plate 2 and can slide along the groove. A roller can be set at the bottom of the sliding plate 72 to roll in the guide rail on the support plate 1 to achieve relative sliding, and the surface of the guide slope is smooth. The first elastic member 73 is a spring, one end of which is hung on the hook of the swing plate 2, and the other end is connected to the second limiting rod 71. The chuck 74 is a metal disc, and the limiting groove 741 and the limiting protrusion 742 are evenly distributed on the edge of the disc and fit each other. When the inspection vehicle needs to brake, the sliding plate 72 is stepped on, and the guiding slope pushes the second limiting rod 71 to overcome the elastic force of the first elastic member 73 and slide toward the wheel set 3, so that the limiting protrusion 742 on the chuck 74 slides into the limiting groove 741 of the chuck 74 of the wheel set 3 to achieve braking.

[0037] This brake assembly is cleverly designed and uses a mechanical structure to achieve efficient braking. Compared with traditional braking methods, it is more precise and reliable, can quickly stop the inspection vehicle, ensure operational safety during track or road inspections, and improve equipment operation safety.

[0038] Furthermore, the second limiting rod 71, the sliding plate 72 and the first elastic member 73 form a brake member 7, each wheel set 3 is correspondingly provided with a brake member 7, and further comprises a sliding rod 8, the sliding rod 8 is slidably provided on the support plate 1, and the sliding plate 72 is provided on the sliding rod 8. The two ends of the second elastic member 9 act on the sliding rod 8 and the support plate 1 respectively, so as to provide a force to guide the inclined surface away from the second limiting rod 71.

[0039] In this embodiment, the slide bar 8 is installed on the support plate 1 through a linear bearing to ensure smooth sliding, and the slide plate 72 is welded to the middle of the slide bar 8. The second elastic member 9 is also a spring, and its two ends are respectively connected to the ends of the slide bar 8 and the fixed columns on the support plate 1 to provide a reset elastic force for the slide bar 8. Each wheel group 3 corresponds to a set of brake components 7. When a brake component 7 is triggered, the slide bar 8 is designed to drive multiple slide plates 72 to slide at the same time, thereby achieving simultaneous braking of multiple brake components 7, adapting to complex terrain and operation requirements, improving the control flexibility and adaptability of the inspection vehicle, and ensuring the accurate inspection operation.

[0040] Furthermore, it also includes a limit push rod 10, which is arranged on the armrest 6. The limit push rod 10 has a vertical surface 101 and an inclined surface 102. The vertical surface 101 is parallel to the armrest 6, and both ends of the inclined surface 102 are connected to the vertical surface 101 and the side wall of the armrest 6. The sliding rod 8 slides relative to the support plate 1 after abutting against the inclined surface 102 and the vertical surface 101.

[0041] In this embodiment, the limit push rod 10 is welded below the handrail 6, the vertical surface 101 is parallel to the handrail 6 and smooth, the inclined surface 102 is a slope, and a roller can be set at the end of the slide bar 8 to roll and abut against the inclined surface 102 and the vertical surface 101. When the operator needs to brake, he holds the handrail 6 and presses it forward and downward, and the limit push rod 10 moves accordingly. The inclined surface 102 first contacts the roller at the end of the slide bar 8, pushing the slide bar 8 to slide, triggering the brake member 7, and realizing linkage braking. The handrail 6 operation is linked to the brake system through the limit push rod 10, and the operator does not need to bend over or stretch out his hand to operate the brake. In the daily process of pushing the inspection vehicle, the brake can be easily applied at any time, which optimizes the operation process, improves the operation efficiency and human-computer interaction, and makes the inspection operation smoother.

[0042] Furthermore, it also includes a driving rod 11, which is rotatably arranged on the swing plate 2; one end of the rotating sleeve 12 is threadedly connected to the driving rod 11, and the other end is used to connect with the wheel set 3.

[0043] Furthermore, the wheel assembly 3 has a snap-in groove 13 at one end close to the driving rod 11, and the rotating sleeve 12 has a snap-in protrusion. The driving rod 11 is rotated and slidably arranged relative to the swing plate 2. After the driving rod 11 slides, the snap-in protrusion is snap-fitted with the snap-in groove 13. It also includes a top screw 14, which is threadedly connected to the swing plate 2. The top screw 14 is used to tighten the driving rod 11.

[0044] In this embodiment, the driving rod 11 is installed on the swing plate 2 through a shaft sleeve, and can rotate around the axis and slide axially. A thread is arranged inside one end of the rotating sleeve 12, which is threadedly connected to the driving rod 11, and the clamping protrusion at the other end is adapted to the clamping groove 13 of the wheel set 3. For example, when the wheel set 3 needs to be disassembled for maintenance or replacement, the driving rod 11 is rotated to slide backward, and the thread transmission drives the rotating sleeve 12 to disengage from the clamping groove 13 of the wheel set 3, and the wheel set 3 can be removed. The brake member 7 is replaced by the driving rod 11, and the driving member can be installed at the other end of the driving rod 11. The power of the driving member is transmitted to the wheel set 3 through the driving rod 11, so that the wheel set 3 is driven to rotate by an external drive. When deceleration or braking is required, the driving member can be directly controlled. The workload of the operator is reduced and physical strength is saved. This combined design of the driving rod 11 and the rotating sleeve 12 provides convenience for the installation and removal of the wheel set 3. No complicated tools are required, and the problem of the wheel set 3 can be quickly handled at the inspection site, reducing the downtime of equipment failure, and improving the continuity of the inspection operation and the efficiency of equipment maintenance. When the inspection vehicle needs to be stored and the support shaft 5 needs to be rotated, the power connection between the wheel set 3 and the driving rod 11 can be disconnected by rotating the sleeve 12 .

[0045] The top screw 14 is made of high-strength stainless steel bolts, which cooperate with the threaded holes of the swing plate 2. A plane is set on the side of the drive rod 11, and the end of the top screw 14 is pressed against the plane. For example, after the wheelset 3 is installed, the top screw 14 is tightened to press the drive rod 11 tightly, so that the inspection vehicle is in a folded state or the drive rod 11 is not connected to the wheelset 3 and the drive member, and the drive rod 11 is in a stable state. As an auxiliary fixing, the top screw 14 further enhances the stability of the connection of the drive rod 11, avoids the drive rod 11 from being knocked and loosened due to vibration, collision and other factors, ensures the reliability of the inspection vehicle in long-term and high-intensity operation in a complex railway environment, and improves the overall performance of the equipment.
