Technical Field
[0001] This utility model relates to the technical field of train uncoupling equipment, specifically a train carriage uncoupling device. Background Technology
[0002] In locations such as thermal power plants, smelters, cement plants, ports, and mines, it is often necessary to transport bulk materials, such as coal, coke, and ore, by train. Bulk materials transported by train are generally unloaded using tippers.
[0003] When a tipper is in operation, the heavily loaded carriages entering the tipper must be separated from the carriages behind them before the tipping operation can begin. Traditionally, the uncoupling of train carriages is done manually. The operator pulls the lifting lever (the iron bar located above the carriage connection) upwards to its limit position, causing the hook lock to separate from the hook tongue, and the coupler to enter the "unlocked" state. However, manual operation has the following problems: (1) High safety risks during manual operation: Operators operate between train carriages, which can easily lead to squeezing and collision accidents.
[0004] (2) Inefficient: Manual operation requires multiple steps and takes a long time, especially in large-scale marshalling yards, where frequent unhooking will affect the overall scheduling efficiency.
[0005] (3) Prone to errors: Due to the complexity of the operation steps, the operator may neglect to fully unlock the coupler, resulting in incomplete separation of the train carriages and causing a safety accident.
[0006] (4) High labor intensity: Unhooking operations are usually carried out outdoors and are greatly affected by the weather (such as high temperature, severe cold, rain and snow), which consumes a lot of physical strength of the operators and long-term work is detrimental to the health of the operators.
[0007] (5) Over-reliance on personal experience: Novices need training to operate skillfully. Differences in operation between different vehicle models and coupler types may lead to incorrect operation, while the loss of experienced personnel will affect the quality of work.
[0008] (6) Not adapted to modern needs: With the increase in freight volume and the speed increase of trains, manual uncoupling is difficult to meet the requirements of efficient and accurate scheduling. Automation and intelligence are the trend, and manual operation may become an obstacle to technological upgrading.
[0009] In recent years, robotic arms have gradually emerged as a method for automated unhooking solutions. However, robotic arms are generally large in size and occupy a lot of space, making them unhooking operations impossible in confined spaces. Utility Model Content

Detailed Implementation
[0022] 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.
[0023] For examples, please refer to Figure 1-9 This utility model provides a technical solution: a train carriage uncoupling device, wherein the telescopic arm 5 includes a support arm shaft 5.1, a lead screw 5.4 disposed in the hollow cavity of the support arm shaft 5.1, a hollow spindle 5.3 located in the inner cavity of the support arm shaft 5.1 and threadedly connected to the lead screw 5.4, and a telescopic tube 5.2 axially slidably sleeved on the outside of the support arm shaft 5.1 and fixedly connected to the outer end of the hollow spindle 5.3 at one end away from the transmission base 1. The support arm shaft 5.1 includes a hollow shaft 5.1.1 fixedly sleeved on the center of the worm gear 1.2 and a hollow arm 5.1.2 fixedly abutted on the end of the hollow shaft 5.1.1 and axially slidably sleeved on the telescopic tube 5.2. A bearing is fitted between the lead screw 5.4 and the hollow shaft 5.1.1, and the hollow spindle 5.3 is slidably sleeved within the hollow arm 5.1.2. The hollow mandrel 5.3 has a nut 5.3.1 that matches the threaded connection of the lead screw 5.4 fixedly sleeved in the inner cavity of the inner end, and a flange 5.3.2 that is fixedly connected to the corresponding end of the telescopic tube 5.2 fixedly at the outer end of the hollow mandrel 5.3.
[0024] A worm gear 1.1 and a worm wheel 1.2 are rotatably mounted inside the transmission base 1, and the end of the support arm shaft 5.1 is fixedly sleeved to the center of the worm wheel 1.2. The end of the hook head 6 is fixedly connected to the outer end of the hollow mandrel 5.3. The hook head 6 includes a main hook 6.1, a side hook 6.2 which is vertically fixed to the side wall of the bent part of the main hook 6.1, and a flange 6.3 fixed to the end of the straight part of the main hook 6.1. The flange 6.3 is fixedly connected to the flange 5.3.2.
[0025] The swing drive 3 and the self-rotation drive 2 are each composed of a motor and a worm gear reducer connected to the motor. The power output shaft of the worm gear reducer of the swing drive 3 is fixed to the outer wall of the transmission base 1, and the power output shaft of the worm gear reducer of the self-rotation drive 2 is fixedly connected to the end of the worm 1.1. The power output shaft of the worm gear reducer of the self-rotation drive 2 is rotatably sleeved with the wall of the transmission base 1. That is, the swing drive 3 is used to drive the transmission base 1 to swing horizontally to realize the horizontal swing operation of the entire telescopic arm 5 and hook 6; the self-rotation drive 2 is used to drive the support arm shaft 5.1 to rotate to realize the self-rotation of the entire telescopic arm 5 and hook 6.
[0026] The telescopic drive component 4 consists of a motor and a planetary gear reducer connected to the motor for transmission. The power output shaft of the planetary gear reducer of the telescopic drive component 4 is fixedly connected to the end of the lead screw 5.4, and the end of the planetary gear reducer is fixedly connected to the corresponding end of the hollow shaft 5.1.1. That is, the telescopic drive component 4 is used to drive the lead screw 5.4 to rotate, so as to realize the axial extension and retraction of the hollow spindle 5.3 and the telescopic sleeve 5.2 relative to the support arm shaft 5.1.
[0027] In summary, when performing the unhooking operation, a three-axis moving system needs to be set up at the position corresponding to the unhooking station. The self-rotation drive component 2 and the swing drive component 3 are fixedly connected to the motion base of the three-axis moving system as fixed components.
[0028] The Z-axis moving mechanism of the three-axis moving system is used to adjust the front and rear position of the hook removal device, the Y-axis moving mechanism is used to adjust the height of the hook removal device, and the X-axis moving mechanism is used to roughly extend the entire hook removal device toward the hook rod to be removed. In other words, the entire three-axis moving system is used to make a rough position adjustment of the hook removal device.
[0029] Then, the motor and planetary gear reducer in the telescopic drive 4 drive the lead screw 5.4 to rotate. The rotating lead screw 5.4 drives the hollow spindle 5.3 through the nut 5.3.1 to drive the telescopic tube 5.2 to extend relative to the support arm shaft 5.1, so as to accurately adjust the hook head 6 to the lifting rod of the carriage.
[0030] The motor and worm gear reducer in the swing drive 3 drive the entire telescopic arm 5 and hook head 6 to swing horizontally through the transmission base 1, so that the side hook 6.2 in the hook head 6 swings to the position corresponding to the inside of the hook rod.
[0031] The telescopic drive 4 drives the telescopic arm 5 to retract, so that the side hook 6.2 is located inside the lifting rod. Then, the rotation drive 2 drives the telescopic arm 5 and the hook head 6 to rotate as a whole, which facilitates the swinging and lifting action of the side hook 6.2 on the lifting rod, so as to quickly complete the hook removal operation.
[0032] To prevent rotation during axial extension and retraction of the telescopic arm 5, the outer peripheral wall of the hollow arm 5.1.2 is provided with a strip-shaped groove 5.1.2.1 extending axially. A guide key 5.5 is fixedly connected within the strip-shaped groove 5.1.2.1. The inner peripheral wall of the telescopic tube 5.2 is provided with an inner keyway 5.2.1 that slides and engages with the guide key 5.5 axially. That is, when the lead screw 5.4 drives the hollow spindle 5.3 and the telescopic tube 5.2 to extend and retract relative to the support arm shaft 5.1 via the nut 5.3.1, the inner keyway 5.2.1 slides relative to the guide key 5.5, achieving a guiding and positioning function, thereby preventing rotation during extension and retraction.
