Description

Technical Field

[0001] The present application relates to the field of railway inspection technology, and in particular to a portable two-fold train inspection tool capable of carrying inspection equipment. Background Art

[0002] With the rapid development of railway passenger and freight transportation, train mileage continues to climb, and the requirements for train safety are becoming increasingly stringent. As a vital component of trains, the technical condition of the train underframe is directly related to the safety and stability of the train's operation. Therefore, timely, comprehensive, and accurate technical inspections of the train underframe are crucial for preventing train accidents and ensuring railway transportation safety.

[0003] However, traditional train inspections, primarily based on manual inspections, have numerous shortcomings. While manual inspections can reveal some obvious faults in visible parts of the train, they often struggle to reach or accurately assess hidden areas or complex structures. This is especially true when manual inspections require drilling under the train or leaning over to inspect. This not only increases safety risks for inspectors, but also easily leads to omissions or misjudgments due to limited visibility and awkward operation.

[0004] Therefore, the present application provides a portable two-fold train inspection tool that can carry detection equipment to solve the above problems. Utility Model Content

[0005] The present application provides a portable two-fold train inspection tool that can be equipped with detection equipment, aiming to solve the problems raised in the background technology that the existing train inspection work is carried out through manual inspection, which makes it difficult to comprehensively and accurately detect hidden parts or complex structures of the train, increases the safety risks of inspectors, and easily leads to omissions or misjudgments in inspections.

[0006] To achieve the above objectives, the present application provides the following technical solutions: a portable two-foldable train inspection tool capable of carrying inspection equipment, comprising a storage shell, a through slot provided in the storage shell, a handheld shell fixedly connected to one end of the storage shell and communicating with the through slot, and a folding structure provided within the storage shell and the handheld shell for carrying the inspection equipment;

[0007] The folding structure includes a primary folding plate rotatably arranged in the through slot for carrying the detection equipment, a secondary folding plate rotatably arranged in the through slot corresponding to one side of the primary folding plate for extending the length of the primary folding plate, and a primary driving member and a secondary driving member arranged in the through slot and the handheld shell for respectively driving the primary folding plate and the secondary folding plate to fold or unfold; through the continuous unfolding of the primary folding plate and the secondary folding plate, not only can the operating range be significantly expanded without frequently moving the tool position, thereby improving the detection efficiency, but the unfolding angle can also be adjusted to adapt to different detection ranges or complex working space environments, solving the shortcomings of drilling under the vehicle and leaning over for inspection during traditional train inspection operations, and improving the detection flexibility and safety. At the same time, by setting up the primary driving member and the secondary driving member to drive, the operation of the folding structure is simplified, so that the tool can be quickly and easily unfolded and folded, and the tool is small in size after folding, easy to store and carry, saving space and having a small and light structure.

[0008] Preferably, in order to facilitate the deployment and folding of the first-level folding plate, the first-level driving component includes a first-level rack that sequentially passes through the hand-held shell and the through slot and is slidably connected to the hand-held shell and the through slot, a first-level shaft key that is rotatably connected to the side wall of the through slot corresponding to a position above the first-level rack and fixedly connected to one end of the first-level folding plate, and a first-level driving gear that is fixedly sleeved on the first-level shaft key and located between the first-level rack and the side wall of the through slot, the bottom end of the first-level driving gear is meshed with the top end of the first-level rack; by moving the first-level rack, the first-level driving gear can be driven to rotate, thereby driving the first-level shaft key and the first-level folding plate to rotate, thereby realizing the deployment and folding of the first-level folding plate. This operation method is simple, intuitive, and easy to master.

[0009] The folding plate is folded and the secondary folding plate is folded and the secondary driving member is connected with the secondary rack in a sliding manner.

[0010] Preferably, in order to limit the movement of the secondary rack and the primary rack, guide grooves are provided at the positions of the through grooves corresponding to the secondary rack and the primary rack, and the secondary rack and the primary rack are slidably connected in the two guide grooves respectively; the design of the guide grooves provides a clear movement path and restriction for the secondary rack and the primary rack, ensuring that the secondary rack and the primary rack move within a specific range and avoid deviating from the range of movement, thereby ensuring the stability and accuracy of the folding structure.

[0011] Preferably, in order to facilitate driving the secondary rack and the primary rack, the secondary rack and the primary rack are fixedly connected to one end of the handheld shell close to the handheld shell; the design of the curved handle provides a larger operating area and a more comfortable grip, allowing the operator to grasp it more easily, so that the operator can drive the secondary rack and the primary rack to move faster, thereby shortening the unfolding and folding time of the folding structure and improving work efficiency.

[0012] Preferably, in order to facilitate the use of the curved handles, the hand-held shell is provided with a toggle groove for the two curved handles to pass through at the positions corresponding to the two curved handles, and the ends of the two curved handles away from the secondary rack and the primary rack are respectively slidably connected to the two in the toggle grooves; the toggle grooves provide a clear operating space and path for the curved handles, so that the operator can intuitively see and grasp the handles to operate, reducing the difficulty of operation.

[0013] Preferably, in order to achieve locking of the folding structure after unfolding or folding, the toggle groove is fixedly provided with tooth-shaped latches distributed in a linear array for clamping and limiting the curved handle; since the tooth-shaped latches are distributed in a linear array, multiple locking positions can be provided, which allows the folding structure to stay at different angles or lengths when unfolded or folded, meeting different operating requirements.

[0014] This portable, dual-folding train inspection tool, which can carry inspection equipment, can significantly expand its operating range by continuously unfolding its primary and secondary folding plates, eliminating the need for frequent tool movement and improving inspection efficiency. It can also adjust the unfolding angle to accommodate different inspection ranges or complex working environments, resolving shortcomings of traditional train inspections such as drilling under the train and requiring probing, thereby improving inspection flexibility and safety.

[0015] This portable two-fold train inspection tool that can carry inspection equipment is driven by a primary drive member and a secondary drive member, which simplifies the operation of the folding structure, allowing the tool to be quickly and easily unfolded and folded. After folding, the tool is compact and easy to store and carry, saving space and having a compact and lightweight structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] This embodiment provides a portable two-fold train inspection tool that can carry inspection equipment, such as Figure 1-Figure 7 As shown, the two-fold train inspection tool includes a storage shell 1, a through slot 11 opened on the storage shell 1, a handheld shell 2 fixedly connected to one end of the storage shell 1 and connected to the through slot 11, and a folding structure 3 arranged in the storage shell 1 and the handheld shell 2 for carrying the detection equipment; the folding structure 3 includes a first-level folding plate 31 rotatably arranged in the through slot 11 for carrying the detection equipment, a second-level folding plate 32 rotatably arranged in the through slot 11 on the side corresponding to the first-level folding plate 31 for extending the length of the first-level folding plate 31, and a first-level driving member 33 and a second-level driving member 34 arranged in the through slot 11 and the handheld shell 2 for respectively driving the first-level folding plate 31 and the second-level folding plate 32 to fold or unfold.

[0030] When the tool is in use, the first folding plate 31 and the second folding plate 32 are both folded in the storage shell 1. When the tool needs to be used to carry the detection equipment for train inspection, the operator can hold the handheld shell 2 and then drive the first driving member 33 and the second driving member 34 according to the space range and requirements of the train inspection. When the first driving member 33 is driven, it will drive the first folding plate 31 to rotate in the through slot 11 and gradually unfold. When the second driving member 34 is driven, it will drive the second folding plate 32 to rotate and gradually unfold to extend the length of the first folding plate 31. When the first folding plate 31 and the second folding plate 32 are unfolded to the desired position, the operator pauses the driving of the first driving member 33 and the second driving member 34, and can unfold the first folding plate 31 and the second folding plate 32 to the desired angle or length to meet the detection requirements of different space ranges. After the detection is completed, the second driving member 34 and the first driving member 33 are driven to fold the second folding plate 32 and the first folding plate 31 back into the through slot 11.

[0031] Specifically, the primary driving member 33 includes a primary rack 331 that sequentially passes through the handheld shell 2 and the through slot 11 and is slidably connected to the handheld shell 2 and the through slot 11, a primary shaft key 333 that is rotatably connected to the side wall of the through slot 11 at a position above the primary rack 331 and fixedly connected to one end of the primary folding plate 31, and a primary driving gear 332 that is fixedly sleeved on the primary shaft key 333 and located between the primary rack 331 and the side wall of the through slot 11. The bottom end of the primary driving gear 332 is meshed with the top end of the primary rack 331.

[0032] Then, the first driving gear 332 will drive the first folding plate 31 through the first shaft key 333, causing it to rotate in the opposite direction around the fixed point and gradually fold and retract into the through slot 11.

[0033] Furthermore, the secondary driving member 34 includes a secondary rack 341 that passes through the hand-held shell 2 and the through slot 11 in sequence and is slidably connected to the hand-held shell 2 and the through slot 11 corresponding to the first-level rack 331 on the side close to the first-level folding plate 31, a transmission synchronous belt gear 345 that is rotatably arranged at a position above the secondary rack 341 and is rotatably connected to the end of the first folding plate 31 away from the first-level shaft key 333, a secondary shaft key 342 that is rotatably connected to the through slot 11 on the side away from the first-level shaft key 333 and located above the secondary rack 341, a driving synchronous belt gear 343 fixedly sleeved on the secondary shaft key 342 and meshed with the top of the secondary rack 341, and a synchronous belt 344 arranged on the driving synchronous belt gear 343 and the transmission synchronous belt gear 345. The driving synchronous belt gear 343 and the transmission synchronous belt gear 345 are connected and transmit power through the synchronous belt 344, and the transmission synchronous belt gear 345 is fixedly connected to one end of the secondary folding plate 32 away from the first-level folding plate 31.

[0034] It should be added that the width of the driving synchronous belt gear 343 is greater than the width of the synchronous belt 344 , half of the area of ​​the driving synchronous belt gear 343 is engaged with the top of the secondary rack 341 , and the other half is connected to the synchronous belt 344 .

[0035] When the first folding plate 31 is unfolded, the synchronous belt 344, the transmission synchronous belt gear 345, the driving synchronous belt gear 343 and the second folding plate 32 will also rotate synchronously with the unfolding of the first folding plate 31, and rotate from a horizontal rotation state to a vertical state in the through slot 11. After the first folding plate 31 is unfolded to the required position, the second rack 341 is driven to move in the through slot 11. Since the second rack 341 is meshed with the driving synchronous belt gear 343 connected to the secondary shaft key 342, when the second rack 341 moves, the driving synchronous belt gear 343 will rotate synchronously. At the same time, since the driving synchronous belt gear 343 and the transmission synchronous belt gear 345 are connected to transmit power through the synchronous belt 344, when the driving synchronous belt gear 343 rotates, the transmission synchronous belt gear 343 The step belt gear 345 will also rotate synchronously, so that the transmission synchronous belt gear 345 will drive the connected secondary folding plate 32 to rotate and unfold around its fixed point, so that the length of the primary folding plate 31 can be extended. After the secondary folding plate 32 is unfolded to the required position, the drive of the secondary rack 341 can be paused. When the secondary folding plate 32 needs to be folded, the secondary rack 341 is first moved in the opposite direction. Through the connection of the secondary shaft key 342, the driving synchronous belt gear 343 will rotate in the opposite direction. Then, the driving synchronous belt gear 343 will be connected through the synchronous belt 344 and transmit power to synchronously drive the transmission synchronous belt gear 345 to rotate, so that the transmission synchronous belt gear 345 will drive the secondary folding plate 32 to rotate and fold around its fixed point. After that, the primary rack 331 is moved in the opposite direction, so that the primary folding plate 31 is folded back into the through slot 11, and the secondary folding plate 32 can be synchronously folded back into the through slot 11 in a vertical state and in a horizontal state.

[0036] Among them, in order to limit the movement of the secondary rack 341 and the primary rack 331, guide grooves 111 are opened at the positions of the through groove 11 corresponding to the secondary rack 341 and the primary rack 331, and the secondary rack 341 and the primary rack 331 are respectively slidably connected in the two guide grooves 111; the design of the guide grooves 111 provides a clear movement path and restriction for the secondary rack 341 and the primary rack 331, ensuring that the secondary rack 341 and the primary rack 331 move within a specific range, avoiding deviation from the range of movement, thereby ensuring the stability and accuracy of the folding structure 3.

[0037] Furthermore, one end of the secondary rack 341 and the primary rack 331 close to the handheld shell 2 is fixedly connected to a curved handle 4.

[0038] It can be understood that in order to facilitate the use of the curved handles 4, the hand-held shell 2 is provided with a toggle groove 21 for the two curved handles 4 to pass through at the positions corresponding to the two curved handles 4, and the two curved handles 4 are slidably connected in the toggle groove 21 at one end away from the secondary rack 341 and the primary rack 331; the toggle groove 21 provides a clear operating space and path for the curved handles 4, so that the operator can intuitively see and grasp the handle to operate, reducing the difficulty of operation.

[0039] When it is necessary to move the first-level rack 331 and the second-level rack 341 to realize the expansion or folding of the first-level folding plate 31 and the second-level folding plate 32, the operator can directly manually toggle the curved handle 4 at the corresponding toggle groove 21. By pushing the curved handle 4 back and forth in the toggle groove 21, the first-level rack 331 and the second-level rack 341 can be moved in their corresponding guide grooves 111.

[0040] Furthermore, the toggle slot 21 is fixedly provided with toothed latches 211 distributed in a linear array for clamping and limiting the curved handle 4; since the toggle slot 21 is provided with toothed latches 211 distributed in a linear array, it can provide multiple locking positions for the curved handle 4. When the curved handle 4 connected to the corresponding first-level rack 331 and the second-level rack 341 is moved, the first-level rack 331 and the second-level rack 341 are driven to move, so that the first-level folding plate 31 and the second-level folding plate 32 are unfolded or folded, when the first-level folding plate 31 and the second-level folding plate 32 are folded or unfolded to a certain angle or length and position, at this time, the corresponding curved handle 4 is clamped into the corresponding toothed latch 211. The position of the curved handle 4 can be locked by the blocking of the toothed latch 211 to ensure that the curved handle 4 will not move at will, and then the first-level folding plate 31 and the second-level folding plate 32 can be locked at a certain position, angle or length.

[0041] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
