Abstract
Description
Technical Field
[0001] The invention relates to the technical field of thermal power generation, in particular to a vertical roller rope-tangling prevention device for a shunting iron ox winch. Background Art
[0002] Shunting oxen replace locomotives in the coal transportation system, reducing investment and avoiding the difficulty in coordination between loading and unloading drivers and locomotive drivers caused by human factors. This saves manpower while making traction and unloading operations more coordinated and coherent. Shunting oxen are easy to operate, highly reliable, and have high loading and unloading efficiency. The problem of wire rope tangling caused by unidirectional output oxen has always been a pain point in the industry. By installing vertical rollers in front of the ox winch and using the vertical rollers as guide devices at the winch entrance, the problem of wire rope cross-entanglement on the winch can be effectively reduced, effectively eliminating the problem of tangled ropes and significantly improving the safety and stability of shunting operations. Summary of the Invention
[0003] The main purpose of the present invention is to provide a vertical roller anti-rope tangling device for a shunting iron bull winch, which can effectively solve the problem of cross-winding of wire ropes on the winch.
[0004] To achieve the above object, the technical solution adopted by the present invention is:
[0005] A vertical roller anti-rope tangling device for a shunting iron bull winch includes a device base, one end of which is provided with a drive assembly, the upper end of the device base is rotatably mounted with a winch through a mounting bracket, and a roller is also rotatably mounted on the middle part of the front side of the device base.
[0006] Preferably, a reducer is provided between the drive assembly and the winch.
[0007] Preferably, the roller is installed 30 cm in front of the capstan, and the axial direction of the roller is perpendicular to the traction direction of the wire rope, so that the contact point of the wire rope is displaced 160 mm to the transmission gear side, forming an incident angle of 7.6°.
[0008] Preferably, the roller includes a cylindrical tube body, a central shaft, a sleeve, a flange and a gasket.
[0009] Preferably, the cylindrical tube is made of Q235 steel, and the surface is quenched;
[0010] The shaft sleeve is made of HT300 wear-resistant cast iron and has an interference fit with the pipe body;
[0011] The central shaft and the shaft sleeve are in clearance fit, allowing the shaft sleeve to rotate freely on the central shaft.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The present invention adopts rollers as the guide device at the entrance of the capstan. Through the specific installation position and angle setting, the winding direction of the wire rope is constrained, so that the contact point of the wire rope is displaced 160mm to the side of the transmission gear, forming an incident angle of 7.6°, effectively reducing the cross winding of the wire rope on the capstan and eliminating the problem of tangled ropes.
[0014] 2. The present invention uses rollers to convert the sliding friction between the wire rope and the capstan into rolling friction, reducing the surface wear of the wire rope and extending its service life. At the same time, the reducer plays a role in reducing speed, increasing torque and buffering, so that the speed and torque of the capstan match the traction load of the wire rope, preventing the wire rope from jumping or slipping due to power output mismatch, reducing the causes of rope tangling from the source, and significantly improving the safety and stability of shunting operations.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1 and Figure 2 As shown, a vertical roller anti-rope tangling device for a shunting iron ox winch includes a device base 1, and a drive component 2 is provided at one end of the device base 1. The drive component 2 is used as a power source for the device. A winch 4 is rotatably installed on the upper end of the device base 1 through a mounting bracket 3, wherein the device base 1 is fixedly connected to the mounting bracket 3, and the mounting bracket 3 is rotatably connected to the winch 4, so that the winch 4 can rotate relative to the device base 1. The winch 4 is used for winding a wire rope, and a roller 6 is also rotatably installed in the middle of the front side of the device base 1.
[0020] In addition, a reducer 5 is provided between the drive assembly 2 and the winch 4, wherein the output end of the drive assembly 2 is connected to the input end of the reducer 5, and the connecting shaft of the winch 4 is connected to the output end of the reducer 5. The reducer 5 is a prior art and can play the role of reducing speed and increasing torque. Since the shunting iron ox winch requires a stable low-speed and high-torque output when in use, the design of the reducer 5 is adopted to reduce speed and increase torque, so that the speed and torque of the winch 4 match the traction load of the wire rope, preventing the wire rope from jumping or slipping on the winch 4 due to power output mismatch, reducing the cause of rope tangling from the source, and the reducer 5 can also play a buffering role. When the motor starts or stops, the gear transmission system of the reducer 5 can buffer the sudden change in power, avoiding the wire rope from jumping violently on the winch 4 due to instantaneous tension impact, and the stable torque output by the reducer 5 keeps the wire rope in constant tension.
[0021] Idlers 6 are installed 30cm in front of capstan 4, with their axis perpendicular to the direction of the wire rope pulling. This displaces the wire rope contact point 160mm toward the drive gear, creating a 7.6° angle of incidence. Driven by the wire rope, idlers 6 rotate freely, following the direction of the rope's movement in real time. When the ox starts or brakes, the rolling friction of idlers 6 absorbs fluctuations in the rope's tension, preventing rope loop jumps caused by transient impacts. Idlers 6 convert the sliding friction between the rope and capstan 4 into rolling friction, significantly reducing wear on the rope's surface.
[0022] The working steps of this embodiment are:
[0023] 1. Preparation
[0024] Fix one end of the wire rope in the rope groove of the capstan 4 and clamp it with a special clamp. Lay the other end along the trench guide wheel and connect it to the shunting iron bull to ensure that the wire rope is stretched and has no knots. Install the roller 6 at an appropriate position in front of the capstan 4, adjust its axial direction to be perpendicular to the traction direction of the wire rope, and move it laterally to the set position so that the wire rope forms a specific incident angle before entering the capstan 4. Calibrate the angle accuracy with professional tools.
[0025] 2. Power transmission system start-up
[0026] The drive assembly 2 is started through the electronic control system, and a soft start method is adopted to avoid sudden power changes and ensure the smooth operation of the motor; the motor power is transmitted to the capstan 4 after being reduced in speed and increased in torque by the reducer 5. The gear system of the reducer 5 converts the high speed into the low speed required by the capstan 4, and at the same time amplifies the torque to match the wire rope traction load, thereby buffering the power impact during startup or shutdown; the capstan 4 starts to rotate under the drive of the reducer 5, winding the wire rope at an appropriate linear speed, and providing stable power for the traction train.
[0027] 3. Dynamic guiding process of roller 6
[0028] The wire rope is passed around the side of the roller 6, maintaining a reasonable wrap angle. The roller 6 rotates freely under the drive of the wire rope and follows the movement direction of the wire rope in real time. The roller 6 constrains the winding direction of the wire rope by a preset incident angle to prevent the rope loops from cross-winding. At the same time, it absorbs the wire rope tension fluctuations through rolling friction to avoid the rope loops from jumping due to instantaneous impact during starting or braking. The roller 6 converts the sliding friction between the wire rope and the winch 4 into rolling friction, reducing the surface wear of the wire rope and extending its service life.
[0029] 4. The whole process of shunting operation
[0030] The winch 4 rotates continuously, pulling the train toward the unloading point through the wire rope. The reducer 5 ensures stable torque output to avoid power fluctuations causing the wire rope to slip. After unloading is completed, the motor reverses, and the winch 4 rotates in the opposite direction to pull the iron cow back to its initial position. The roller 6 continues to guide to ensure that the wire rope is unwound in an orderly manner.
[0031] 5. Shutdown and Maintenance
[0032] After the operation is completed, turn off the motor and let the reducer 5 buffer the sudden change in power during shutdown to prevent the wire rope from loosening due to inertia; regularly check the rotation flexibility of the roller 6, the tightness of the mounting bracket 3 and the condition of the wire rope, and add grease in time to ensure the reliable guiding function of the roller 6; if any parts are found to be worn or abnormal, replace or repair them in time.
[0033] It should be noted that the specific installation methods, circuit connection methods and control methods of the winch 4, reducer 5 and roller 6 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
