Abstract
Description
Technical Field
[0001] This invention relates to the field of automatic coupling and uncoupling technology for electric locomotives, and in particular to an automatic coupling and uncoupling method for unmanned battery-powered electric locomotives and its usage. Background Technology
[0002] An unmanned battery-powered locomotive is a type of locomotive that uses batteries as its power source. It can achieve automated operation without the need for a driver, thereby reducing labor costs, improving production efficiency, avoiding human error by the driver, reducing the possibility of accidents, and improving safety.
[0003] While traditional driverless battery-powered locomotives can reduce labor costs and improve production efficiency, the hook technology used between the two carriages cannot automatically feed back the connection and disconnection results to the central control system. If the hook malfunctions or fails to connect properly, the two carriages cannot be connected smoothly, and the staff will not know that the carriage connection has failed. This will cause subsequent handling work to be unable to continue and will also affect work efficiency. Summary of the Invention
[0004] In order to solve the problems existing in the background art, the present invention provides a battery-powered electric locomotive automatic uncoupling and hooking system that can transmit the automatic connection and disconnection results of electric locomotives in unmanned driving mode to the central control system.
[0005] To address the problems in the prior art, this invention provides an automatic hook-and-unhook mechanism for an unmanned battery-powered electric locomotive, comprising a first carriage and a second carriage. A locking assembly is fixedly installed on one side of the first carriage. The locking assembly includes a fixed cylinder, a slot, a sensor, a slide rail, a first double-headed electric push rod, a slider, a connecting block, a connecting rod, and a semi-circular disc. One end of the fixed cylinder is fixedly connected to one side of the first carriage. The sensor is fixedly installed inside the fixed cylinder and electrically connected to the first double-headed electric push rod, a second double-headed electric push rod, and a signal transceiver. The first double-headed electric push rod is fixedly installed inside the fixed cylinder and located below the sensor. A connecting assembly is fixedly installed on one side of the second carriage. The connecting assembly includes a mounting plate, a connecting column, a limiting ring, a semi-circular cylinder, a limiting plate, and a second double-headed electric push rod. The two output shafts of the second double-headed electric push rod are respectively fixedly connected to one side of a set of limiting plates.
[0006] Specifically, the outer wall of the fixed cylinder has two sets of slots, the inner wall of the fixed cylinder has two sets of slots, a set of slide rails is fixedly installed at the connection between the fixed cylinder and the first carriage, a set of two sets of sliders are slidably connected in the slide rails, a set of connecting blocks is fixedly connected to the upper end of each set of sliders, and a set of output shafts of the first double-headed electric actuator is fixedly connected to one side of each set of connecting blocks.
[0007] Specifically, the upper end of the connecting block is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the bottom end of the semi-circular disk. There is a certain gap between the semi-circular disk and the fixed cylinder.
[0008] Specifically, an installation plate is fixedly connected to one side of the second carriage, and one end of a connecting column is fixedly connected to one side of the installation plate. A set of limiting rings is fixedly connected to the outer wall of the end of the connecting column near the installation plate. Two sets of semi-cylinders are fixedly connected to the other end of the connecting column. Two sets of second double-headed electric push rods are slidably connected inside the two sets of semi-cylinders. A set of limiting plates is fixedly connected between the two sets of second double-headed electric push rods.
[0009] Specifically, a set of signal transceivers is fixedly installed inside the first carriage, and a set of wheels is fixedly installed at the bottom of the first carriage. The internal and bottom structures of the second carriage are the same as those of the first carriage.
[0010] Includes the following steps:
[0011] S1. When two sets of carriages need to be connected to transport goods, the first carriage and the second carriage begin to approach each other along the track. After the semi-cylinder contacts the sensor, the sensor will transmit a signal to the central control system. At this time, the central control system will control the first double-headed electric push rod to start. The first double-headed electric push rod is fixedly installed inside the fixed cylinder. At this time, the first double-headed electric push rod begins to retract, which will drive the two sets of sliders to slide inside the slide rail. The connecting rod will move together with the sliders.
[0012] S2. When the connecting rod is fully inserted into the slot on the outer wall of the fixed cylinder, the first double-headed electric actuator stops retracting. At this time, the two sets of semi-circular discs will lock the limiting ring into the limiting groove inside. At the same time as the first double-headed electric actuator starts, the second double-headed electric actuator also starts, which will drive the two sets of limiting plates to extend outward, thereby locking the limiting plates into the slots on the inner wall of the fixed cylinder.
[0013] S3. When the work is completed and it is necessary to disconnect the two sets of carriages, the staff operating the central control system only needs to control the first double-headed electric push rod and the second double-headed electric push rod to reset, and the hooks on the two sets of carriages can be released. This not only connects the two sets of carriages together, but also transmits the automatic connection and disconnection results of the hooks to the central control system for the convenience of the staff to observe.
[0014] The beneficial effects of this invention: This invention provides an automatic hook-and-unhook mechanism for an unmanned battery-powered electric locomotive. When the semi-cylinder installed on the second carriage contacts the sensor, the sensor transmits a signal to the central control system. The central control system then controls the first double-headed electric push rod to start. The first double-headed electric push rod begins to retract, stopping when the connecting rod is fully inserted into the slot on the outer wall of the fixed cylinder. At this point, the two sets of semi-circular discs clamp the limiting ring into the limiting groove inside. Simultaneously with the start of the first double-headed electric push rod, the second double-headed electric push rod also starts, causing the two sets of limiting plates to extend outwards, thereby engaging the limiting plates in the slots on the inner wall of the fixed cylinder. This not only connects the two carriages together but also transmits the automatic hook-and-unhook connection and disconnection results to the central control system, facilitating observation by the staff.

[0026] To make the technical methods, creative features, objectives, and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0027] like Figure 1-9 As shown, to address the problems in the prior art, the present invention provides an automatic uncoupling and hooking mechanism for an unmanned battery-powered electric locomotive, comprising a first carriage 1 and a second carriage 2. A locking assembly 3 is fixedly installed on one side of the first carriage 1. The locking assembly 3 includes a fixing cylinder 310, a locking slot 311, a sensor 312, a slide rail 313, a first double-headed electric push rod 314, a slider 315, a connecting block 316, a connecting rod 317, and a semi-circular disk 318. One end of the fixing cylinder 310 is fixedly connected to one side of the first carriage 1, and the sensor 312 is fixedly installed inside the fixing cylinder 310. The sensor 312 is electrically connected to the first dual-head electric actuator 314, the second dual-head electric actuator 415, and the signal transceiver 111. The first dual-head electric actuator 314 is fixedly installed inside the fixed cylinder 310 and located below the sensor 312. The connecting assembly 4 is fixedly installed on one side of the second carriage 2. The connecting assembly 4 includes a mounting plate 410, a connecting column 411, a limiting ring 412, a semi-cylinder 413, a limiting plate 414, and the second dual-head electric actuator 415. The two output shafts of the second dual-head electric actuator 415 are respectively fixedly connected to one side of a set of limiting plates 414.
[0028] Preferably, the outer wall of the fixed cylinder 310 has two sets of slots, and the inner wall of the fixed cylinder 310 has two sets of slots 311. A set of slide rails 313 is fixedly installed at the connection between the fixed cylinder 310 and the first carriage 1. A set of two sets of sliders 315 are slidably connected in the slide rails 313. A set of connecting blocks 316 is fixedly connected to the upper end of each set of sliders 315. A set of output shafts of the first double-headed electric actuator 314 is fixedly connected to one side of each set of connecting blocks 316. One end of the connecting rod 317 is fixedly connected to the upper end of the connecting block 316, and the other end of the connecting rod 317 is fixedly connected to... At the bottom of the semicircular disk 318, there is a certain gap between the semicircular disk 318 and the fixed cylinder 310. An installation plate 410 is fixedly connected to one side of the second carriage 2. One end of the connecting column 411 is fixedly connected to one side of the installation plate 410. A set of limiting rings 412 is fixedly connected to the outer wall of the end of the connecting column 411 near the installation plate 410. Two sets of semicircular cylinders 413 are fixedly connected to the other end of the connecting column 411. Two sets of second double-headed electric push rods 415 are slidably connected inside the two sets of semicircular cylinders 413. A set of limiting plates 414 is fixedly connected between the two sets of second double-headed electric push rods 415.
[0029] (1) When the semi-cylinder 413 installed on the second carriage 2 contacts the sensor 312, the sensor 312 will transmit a signal to the central control system. At this time, the central control system will control the first double-headed electric actuator 314 to start. The first double-headed electric actuator 314 begins to retract. When the connecting rod 317 is fully inserted into the slot on the outer wall of the fixed cylinder 310, it stops retracting. At this time, the two sets of semi-circular discs 318 will clamp the limiting ring 412 in the limiting slot inside. At the same time as the first double-headed electric actuator 314 starts, the second double-headed electric actuator 415 also starts. When activated, it will cause the two sets of limiting plates 414 to extend outward, thereby locking the limiting plates 414 into the slots 311 opened in the inner wall of the fixed cylinder 310. After the transportation work is completed, when it is necessary to disconnect the connection between the two sets of carriages, the staff operating the central control system only needs to control the first double-headed electric push rod 314 and the second double-headed electric push rod 415 to reset, and the hooks on the two sets of carriages can be released. The operation is convenient. It can not only connect the two sets of carriages together, but also transmit the automatic connection and disconnection results of hook and hook to the central control system for easy observation by the staff.
[0030] (2) Signal transmission and control both need to go through signal transceiver 111. The central control system (not shown) and sensor 312 both transmit and receive signals through signal transceiver 111, thereby completing the connection and disconnection of the two sets of car hooks.
[0031] An automatic uncoupling and coupling method for an unmanned battery-powered electric locomotive and its usage method include the following steps:
[0032] S1. When two sets of carriages need to be connected to transport goods, the first carriage 1 and the second carriage 2 begin to approach each other along the track. After the semi-cylinder 413 contacts the sensor 312, the sensor 312 will transmit a signal to the central control system. At this time, the central control system will control the first double-headed electric push rod 314 to start. The first double-headed electric push rod 314 is fixedly installed inside the fixed cylinder 310. At this time, the first double-headed electric push rod 314 begins to retract, which will drive the two sets of sliders 315 to slide inside the slide rail 313. The connecting rod 317 will move together with the sliders 315.
[0033] S2. When the connecting rod 317 is fully inserted into the slot on the outer wall of the fixed cylinder 310, the first double-headed electric actuator 314 stops retracting. At this time, the two sets of semi-circular discs 318 will clamp the limiting ring 412 into the limiting groove inside. At the same time as the first double-headed electric actuator 314 starts, the second double-headed electric actuator 415 also starts, which will drive the two sets of limiting plates 414 to extend outward, thereby locking the limiting plates 414 into the slots 311 on the inner wall of the fixed cylinder 310.
[0034] S3. When the work is completed and it is necessary to disconnect the two sets of carriages, the staff operating the central control system only need to control the first double-headed electric push rod 314 and the second double-headed electric push rod 415 to reset, and the hooks on the two sets of carriages can be disconnected. This not only connects the two sets of carriages together, but also transmits the automatic connection and disconnection results of the hooks to the central control system for the convenience of the staff to observe.
