Description

Technical Field

[0001] This invention relates to the field of door control device technology, and more specifically to a convertible door lock switch device. Background Technology

[0002] In the railway transportation sector, whether transporting energy, construction, or machinery, the opening and closing of open wagon door locks is a crucial step, affecting cargo safety, personnel safety, transportation efficiency, environmental protection, and regulatory compliance. Therefore, optimizing the opening and closing operations of open wagon door locks is of great significance for improving the overall quality and efficiency of railway transportation.

[0003] However, most open wagon doors are still opened and closed manually using a hammer. While simple and direct, this method has significant drawbacks: First, frequent hammering can damage the locks, increasing maintenance costs and potentially compromising transport safety. Second, this method poses a safety risk to personnel. Workers could be injured due to improper operation or sudden lock release. Furthermore, due to the limitations of manual operation, this method is relatively inefficient and fails to meet the high-efficiency requirements of modern railway transport.

[0004] Therefore, how to provide a wagon door lock switch device that can improve the opening and closing efficiency of the door lock, avoid damage to the door lock, extend the service life of the door lock, and improve the safety of staff and during transportation is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a convertible door lock switch device, which can improve the opening and closing efficiency of the door lock, avoid damage to the door lock, extend the service life of the door lock, and improve the safety of workers and during transportation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A convertible door lock switch device includes a door lock assembly comprising a stop strip, a latch seat, and a rotary latch. The stop strip crosses the door and one end is movably connected to the vehicle body. The latch seat and the rotary latch are disposed opposite to each other on the vehicle body at the other end of the stop strip in a direction perpendicular to the stop strip. The latch seat is fixed to the vehicle body. One end of the rotary latch is rotatably connected to the vehicle body, and the other end can enter or leave a slot in the latch seat to lock or release the stop strip.

[0008] It also includes: a positioning base plate, a pusher, and a drive assembly; the positioning base plate has a first plate surface and a second plate surface, the first plate surface is detachably connected to the buckle seat, and the second plate surface is provided with an unlocking track groove, a locking track groove, and a pusher starting groove. The unlocking track groove is arranged at the midpoint of the line connecting the buckle seat and the rotation point of the rotating buckle; the locking track groove is arc-shaped and matches the trajectory of the rotating end of the rotating buckle rotating to the slot, and it is arranged on the side of the rotating buckle away from the buckle seat from the rotation point; the pusher starting groove is arranged on the side of the buckle seat away from the slot opening, and it is respectively connected to the first end of the unlocking track groove and the locking track groove;

[0009] One end of the pusher is located in the pusher starting groove and can slide into the unlocking track groove or the locking track groove, while the other end extends toward the rotating buckle and is connected to the rotating buckle in a transmission manner; the drive assembly is connected to the pusher in a transmission manner to drive the pusher to slide along the unlocking track groove or the locking track groove, thereby driving the rotating buckle to rotate to unlock or lock.

[0010] Through the above technical solution, the present invention provides a wagon door lock switch device. The door lock assembly enables the locking or unlocking of the wagon door. The unlocking and locking track grooves allow a pusher to move internally, simultaneously rotating a rotating latch to open and close the door lock, avoiding damage and safety hazards caused by physical impact. The drive assembly enables automated control of the door lock, improving ease of use. Operators can easily control the opening and closing of the wagon door lock, improving operational efficiency and safety. Its simple structure and convenient operation allow for quick and accurate opening of the wagon door lock, preventing damage and extending its lifespan, thus enhancing the safety of workers and during transportation.

[0011] The pushing component travels at a speed of 450-500 mm / s within the unlocking track groove, causing the rotary latch to rotate to the side furthest from its latch seat due to inertia. This structure allows the pushing component to move along the unlocking track groove, thereby rotating the rotary latch. The rotary latch, under inertia, rotates to the side furthest from its latch seat, ensuring the door lock opens.

[0012] The speed at which the pusher moves within the locking track groove can be 100-150 mm / s.

[0013] Furthermore, the pusher is nested with a bearing, which allows for rolling friction along the track groove.

[0014] Furthermore, a fastener is fixed to the vehicle body, and one end of the rotating buckle is rotatably connected to the fastener.

[0015] Two clamping grooves are fixed on the first plate surface. One clamping groove clamps the outer surface of the buckle seat, and the other clamps the outer surface of the fixing component. The two clamping grooves are respectively engaged with the buckle seat and the fixing component to realize the positioning of the positioning substrate.

[0016] This structure ensures precise alignment between the positioning base plate and the door lock assembly.

[0017] Preferably, there are two sets of buckle seats and rotating buckles, and the two rotating buckles enter the corresponding slots in opposite directions.

[0018] There are two sets of locking track grooves, namely track groove one and track groove two, which are arranged opposite each other on both sides of the unlocking track groove.

[0019] This structure allows the locking track groove to accommodate rotating latches in two locking directions.

[0020] Preferably, it also includes a track selection component, which includes a U-shaped rotating component and a rotating positioning block. The U-shaped rotating component is rotatably connected to the starting groove of the pusher, and its cavity can accommodate the pusher. The U-shaped rotating component is driven to rotate, and its open end can be switched to any one of the entry ends of track groove one, track groove two, and unlocking track groove so that the pusher enters the corresponding track groove. Positioning posts are fixed on both sides of the U-shaped rotating component. There are two rotating positioning blocks, one end of which is rotatably connected to the positioning base plate on the side of the locking track groove away from the locking track groove, and the other end is respectively provided with a positioning groove that cooperates with the positioning post on one side of the U-shaped rotating component.

[0021] The design of this structure allows for the selection of the track groove for the pusher, enabling the pusher to move along the corresponding track groove.

[0022] Furthermore, the U-shaped rotating component includes a U-shaped plate, a fixed shaft, a first telescopic spring, and a second telescopic spring. The cavity of the U-shaped plate can accommodate the pushing component, and a U-shaped groove with both ends passing through is opened on the surface of the U-shaped plate. The fixed shaft passes through the middle position of the U-shaped groove and is fixed to the positioning base plate to make the U-shaped plate rotate around the fixed shaft. The first telescopic spring and the second telescopic spring are respectively located in the corresponding U-shaped grooves on both sides of the fixed shaft, and their ends are respectively fixed to the groove wall corresponding to the U-shaped groove and the side wall corresponding to the fixed shaft.

[0023] It also includes a reset assembly, which includes a limit block and a reset plate. The limit block is fixed to the side of the positioning base plate corresponding to the rotating positioning block away from the U-shaped rotating part. One end of the reset plate is fixed to the side of the rotating positioning block away from the opening of the positioning groove. The positioning post is embedded in the positioning groove. The other end of the reset plate is located at the position of the locking track groove and moves towards the limit block under the push of the pusher so that the positioning groove leaves the positioning post.

[0024] The reset plate and the rotating positioning block are integrally formed.

[0025] The open end of the U-shaped rotating component corresponds to the unlocking track groove at the starting position; the pushing component can move along the unlocking track groove;

[0026] When the U-shaped rotating part rotates to the position of the track groove one corresponding to its open end, the first telescopic spring is compressed, the rotating positioning base plate and the positioning groove of the rotating positioning block are hooked into the corresponding positioning block to realize the positioning of the U-shaped rotating part. At this time, the pusher can move along the track groove one, and the other end of the reset plate is located at the position of the track groove one. When the pusher moves, it will pop the reset plate open, the positioning groove will leave the positioning block, and the U-shaped rotating part will return to the initial state.

[0027] When the U-shaped rotating component rotates to the position corresponding to the second track groove at its open end, the second telescopic spring is compressed, the rotating positioning base plate and the positioning groove of the rotating positioning block are hooked into the corresponding positioning block to achieve positioning of the U-shaped rotating component. At this time, the pushing component can move along the second track groove, and the other end of the reset plate is located at the position of the second track groove. When the pushing component moves, it will pop the reset plate open, the positioning groove will leave the positioning block, and the U-shaped rotating component will return to the initial state.

[0028] Preferably, the system also includes a guide plate. A connecting groove is formed at the end of the positioning base plate furthest from the starting groove of the pusher. This connecting groove connects to the ends of both the locking and unlocking track grooves. One end of the guide plate is rotatably connected to the side of the positioning base plate furthest from the end of the locking track groove via a rotating shaft. The other end of the guide plate is located within the connecting groove. A through hole is formed on the surface of the guide plate, and the axial length D1 of the through hole is not less than the length D2 from the rotating shaft to the groove wall of the connecting groove, allowing the plate surface to be perpendicular or parallel to the running direction of the locking track groove. This structure guides the movement direction of the pusher, thereby accurately opening or closing the convertible door lock.

[0029] The guide plate can be set into two sets, which can be called guide plate one and guide plate two, corresponding to track groove one and track groove two respectively.

[0030] When the pusher moves along the unlocking track groove, the door lock can be opened. At this time, under the action of guide plate one and guide plate two, it cannot enter track groove one and track groove two. The positioning base plate can be removed or the pusher can return along the original path.

[0031] When the pusher moves along the first track groove, the door lock is closed. At this time, under the action of the first guide plate and the second guide plate, the pusher can enter the connecting groove, but cannot enter the second track groove or return along the original path. The positioning base plate or the pusher can be disassembled to enter the unlocking track groove.

[0032] When the pusher moves along the second track groove, the door lock is closed. At this time, under the action of the first guide plate and the second guide plate, the pusher can enter the connecting groove, but cannot enter the first track groove or return along the original path. The positioning base plate or the pusher can be disassembled to enter the unlocking track groove.

[0033] Preferably, the drive assembly includes a hydraulic cylinder and a rotary bearing. The cylinder body end of the hydraulic cylinder is rotatably connected to the side of the positioning base plate corresponding to the starting groove of the pusher that is away from the connecting groove. The rotary bearing is located at the telescopic end of the hydraulic cylinder and is connected to the pusher on the side of the hydraulic cylinder closest to the positioning base plate.

[0034] Furthermore, a fixing hole is provided on the second plate surface of the positioning base plate on the side away from the connecting groove of the pusher starting groove, and an installation hole is provided on the cylinder end of the hydraulic cylinder. The rotating shaft passes through the installation hole and the fixing hole in sequence and is rotatably connected to the cylinder end of the hydraulic cylinder, and is fixedly connected to the positioning base plate.

[0035] It also includes a throttle valve, which is installed at the oil inlet of the hydraulic cylinder. The oil flow rate is controlled by manually adjusting the throttle valve, thereby realizing the moving speed of the pusher. The hydraulic cylinder stroke is 100mm, and the single lifting speed is adjustable from 100-500mm / s.

[0036] Furthermore, it also includes a power integration unit, which consists of a motor, a hydraulic pump, a solenoid directional valve, a safety valve, and an oil tank. The power integration unit is connected to the hydraulic cylinder through hydraulic pipelines, and it can provide sufficient force to the hydraulic cylinder to drive the pusher to move, thereby opening and closing the convertible door lock.

[0037] To ensure system safety, pressure switches and safety valves are also installed. The pressure switches monitor the hydraulic system pressure and automatically cut off the hydraulic supply when the pressure exceeds a set range to prevent system overload and damage. The safety valves automatically release pressure in case of abnormal system pressure, protecting the system and operators.

[0038] The hydraulic system enables automatic opening and closing of the open car doors, reducing labor costs and simplifying operation.

[0039] Preferably, it also includes a handheld remote control assembly, which includes a long rod and a handle. One end of the long rod is rotatably connected to the positioning base plate; the handle is fixed to the other end of the long rod and has a control button electrically connected to the hydraulic cylinder. It is convenient to carry and use, provides a comfortable grip and operating experience, and is suitable for different scenarios and environments. The operator can stand in front of the safety fence on the coal unloader and control the pusher to move along different track grooves, thereby opening and closing the open car door.

[0040] The on / off state and flow direction of the oil in the solenoid valve can be adjusted by the control button.

[0041] The outer surface of the grip can be padded and raised to improve operating comfort.

[0042] Regular maintenance of the drive components can be performed, including changing hydraulic oil, cleaning filters, inspecting seals, and tightening bolts. These maintenance measures can effectively reduce system failures and damage, ensure the reliability and stability of the drive components, and extend their service life.
