Description

Technical Field

[0001] This invention relates to the field of rail transit train braking technology, specifically to an anti-slip iron shoe device that can automatically attach the shoe. Background Technology

[0002] Anti-slip shoes are anti-slip devices used to prevent rail transit vehicles (locomotives, rolling stock) from slipping. They are widely used in rail transit departments both domestically and internationally.

[0003] This equipment is generally operated manually, which has the following main drawbacks: First, manual operation results in low work efficiency; second, the process of receiving, placing, inspecting, and returning the anti-slip shoes is complex and requires manual registration and management; and third, workers face personal injury risks when operating in inclement weather. Furthermore, after the anti-slip shoes are installed, they may fall off the track due to vibration, wind, and other environmental factors, losing their anti-slip function and compromising operational reliability; there are also safety risks such as lost or missed anti-slip shoes.

[0004] Currently, some manufacturers at home and abroad have developed anti-theft iron shoes, which have solved the problem of lost iron shoes, but they cannot change the fundamental model of relying on manual operation for iron shoes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an anti-slip iron shoe device that can automatically put on shoes, thereby avoiding manual operation and realizing the automatic shoe-putting process.

[0006] This invention provides an automatic shoe-adjusting anti-slip shoe device, comprising: a fixed plate, which is detachably mounted on a track; a drive mechanism, which includes a drive box, a motor, a reduction gear set, and a drive shaft; the drive box is mounted near the fixed plate and located on one side of the track; the motor is mounted inside the drive box, and the drive shaft is driven by the reduction gear set; and a shoe-adjusting device, which is mounted on one side of the drive mechanism; the shoe-adjusting device includes an anti-slip shoe, a flipping component, a flipping shaft, and a flipping seat; the flipping seat is fixedly mounted on the fixed plate; the flipping shaft is rotatably mounted in the flipping seat, and both ends of the flipping shaft extend outward; wherein one end of the flipping shaft is driven by the drive shaft; the flipping component is detachably mounted on the flipping shaft; and the anti-slip shoe is detachably mounted on the flipping component.

[0007] Furthermore, the reduction gear set has multiple stages of gears that mesh and drive in sequence, including a driving gear, a reduction gear, a first transmission gear, a second transmission gear, a first output gear, and a second output gear. In practical applications, some rotating shafts are also installed in conjunction with the above gears, and these shafts are, in sequence, the driving gear rotating shaft, the reduction gear rotating shaft, the first transmission gear rotating shaft, the second transmission gear rotating shaft, and the first output gear rotating shaft.

[0008] Furthermore, it also includes friction plates, which are disposed between the reduction gear set and the motor. In actual design, the purpose of connecting the reduction gear set to the motor is mainly to increase torque output. To further increase torque, a friction disc is also disposed between the motor and the reduction gear set, located on the rotating shaft of the drive gear. In practical application, this design can achieve the effect of increasing torque. By changing the weight and size of the friction disc, the torque of the rotating shaft of the drive gear is changed, thereby achieving the torque of the drive shaft after meshing transmission, and ultimately changing the torque of the rotating shaft that drives the shoe upper to rotate. At the same time, the friction disc can also achieve a clutch-like engagement and disengagement effect. By the friction disc abutting against the friction disc on the motor output shaft, and by changing the friction disc, the friction force between the friction disc and the drive housing surface is changed; thus, a clutch effect can be achieved, realizing overload protection for the motor.

[0009] Furthermore, it also includes a torque limiting component; the torque limiting component is installed inside the reduction gear set; the torque limiting component includes a torque transmission rod and a limiting sleeve; and the limiting sleeve is provided in two places, and is respectively installed on the reduction gear and the first transmission gear; both ends of the torque transmission rod are respectively connected to the limiting sleeves at the two locations. In practical applications, the purpose of this design is to increase torque, wherein the torque transmission rod is U-shaped, and the limiting sleeve in this design is movably hinged to the torque transmission rod to realize the torque transmission of the torque transmission rod; at the same time, in actual operation, when the drive gear rotating shaft rotates with the motor, it drives the rotation of the reduction gear rotating shaft through the reduction gear, thereby causing the limiting sleeve installed on it to rotate, and thus causing the torque transmission rod to rotate; when the torque transmission rod is near the horizontal position, it corresponds to the upper shoe position and the lower shoe position; at this time, the multi-link torque transmission mechanism composed of the limiting sleeve and the torque transmission rod... The output shaft reaches a "dead point," achieving the first limiting action. Simultaneously, in case of overload, the limiting sleeve hinged to it—specifically, the limiting sleeve at the first transmission gear—will abut against the nearby first transmission gear's rotating shaft, achieving a second limiting protection. To further protect the motor and prevent overtravel, the actual design also includes two limiting blocks to increase the reliability of position locking. These limiting blocks are bolted to the gearbox side plate and located on both sides of the reduction gear's rotating shaft, with their bottom surfaces fixedly connected to the bottom surface of the drive housing. This restricts the reduction gear's rotating shaft to only 180 degrees, ultimately ensuring the tilting shaft can rotate in reverse.

[0010] Furthermore, it also includes a fixing clamp; the fixing clamp is provided in two locations, one of which is detachably mounted on the fixing plate; the other fixing clamp is detachably mounted on the drive box. In practical applications, this design improves interchangeability and ensures that interchangeability can be achieved.

[0011] Furthermore, the fixing clamping component includes a clamping fastener and a fixing bolt, wherein both the fixing plate and the drive box have at least one connecting screw hole seat, the fixing bolt passes through the clamping fastener and is threadedly connected to the connecting screw hole seat; the clamping fastener has an abutment groove, and the abutment groove abuts against the track. In actual design, the clamping fastener can be fixedly installed on the track by rotating the fixing bolt, thereby achieving overall fixation of the device.

[0012] Furthermore, it also includes a coupling, which comprises a coupling and a connecting shaft; there are two connecting shafts, one of which is connected to the drive shaft, and the other is connected to the tilting shaft; the connecting shafts are detachably mounted at both ends of the coupling. In actual design, this connection method can also be replaced by a hinged connection.

[0013] Furthermore, it also includes a monitoring mechanism used to monitor the working displacement status of the shoe-mounting device. In practical applications, the monitoring mechanism monitors the working displacement status of the shoe-mounting device mainly to monitor its flipping effect. In the actual design, the monitoring mechanism includes a shoe position detection component, a torsion spring, and a shoe position indicator. In this design, the shoe position detection component is equipped with at least one proximity sensor, and the shoe position indicator has two detection points, which are spaced 90 degrees apart. The torsion spring is installed in the flipping shaft, and the shoe position indicator is detachably installed on the flipping shaft, located on the torsion spring, and abuts against it. The shoe position indicator is fixedly connected to the flipping shaft. When the flipping shaft rotates, the detection points on the shoe position indicator will rotate accordingly. At this time, the proximity sensor will sense the distance and upload its rotational displacement information to the back-end control system. Through the control system, the motor is driven to rotate, realizing the automatic flipping of the device on the track, and finally realizing the automatic shoe loading and unloading of the anti-slip iron shoes on the specified position. At the same time, the aforementioned torsion spring will achieve a pre-compensation effect on the shoe position indicator that it abuts, thereby reducing the axial displacement of the shoe position indicator.

[0014] Furthermore, the flipping component includes a shoe bracket, a flipping plate, and a fixing block; the fixing block has two locations, which are respectively installed through the flipping shaft; and the fixing block is detachably fixedly installed on the flipping plate, one end of the shoe bracket is installed on the flipping plate, and the other end of the shoe bracket is connected to the anti-slip shoe.

[0015] As can be seen from the above technical solution, the present invention provides a device for automatically attaching anti-slip iron shoes with beneficial effects;

[0016] (1) This device can realize the automatic putting on and taking off of anti-slip iron shoes without manual operation; greatly reducing labor costs;

[0017] (2) At the same time, the external dimensions of the device in this design are smaller than the minimum sleeper spacing requirement, so there is no need to move the sleepers during on-site construction;

[0018] (3) The reduction gear set also has a shoe position locking function. The position is locked in the upper / lower shoe position, and the position cannot be changed manually, making the anti-slip operation reliable.

[0019] (4) Shoe detection can be performed in any working state (up / down shoe position); it has the function of up / down shoe detection and control, simplifying the on-site iron shoe management process; Attached Figure Description

Detailed Implementation

[0032] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0033] The basic implementation examples are as follows: Figures 1 to 9 As shown:

[0034] like Figure 1-3 As shown in the figure, this embodiment provides an anti-slip iron shoe device that can automatically put on and take off shoes, which can avoid manual operation and realize the automatic shoe-putting process.

[0035] This invention provides an automatic shoe-adjustable anti-slip iron shoe device, comprising: a fixing plate 1, which is detachably mounted on a track; a drive mechanism 2, which includes a drive housing 21, a motor 22, a reduction gear set 23, and a drive shaft 24; the drive housing 21 is mounted near the fixing plate 1 and located on one side of the track; the motor 22 is mounted inside the drive housing 21, and the drive shaft 24 is connected to the motor 22 via the reduction gear set 23; and a shoe-adjusting device 3. The device 3 is installed on one side of the drive mechanism 2; the shoe loading device 3 includes an anti-slip shoe 31, a flipping component 32, a flipping shaft 33, and a flipping seat 34; the flipping seat 34 is fixedly installed on the fixed plate 1; the flipping shaft 33 is rotatably installed in the flipping seat 34, and both ends of the flipping shaft 33 extend outward; wherein one end of the flipping shaft 33 is connected to the drive shaft 24 for transmission; the flipping component 32 is detachably installed on the flipping shaft 33; the anti-slip shoe 31 is detachably installed on the flipping component 32. In actual work, this device can realize the automatic shoe loading and unloading function of the anti-slip shoe 31 without manual operation; greatly reducing labor costs; at the same time, the external dimensions of this device are smaller than the minimum sleeper spacing requirement, and there is no need to move the sleepers on site; the reduction gear set 23 also has a shoe position locking function, and the position is locked when the shoe is in the upper / lower position, and the position cannot be changed manually, so the anti-slip operation is reliable; shoe movement detection can be realized in any working state (upper / lower shoe position); it has the function of shoe loading / unloading inspection and control, simplifying the on-site shoe management process;

[0036] To achieve speed reduction transmission, in this embodiment, the reduction gear set 23 is provided with multiple stages of gears that mesh sequentially, including a driving gear 231, a reduction gear 232, a first transmission gear 233, a second transmission gear 234, a first output gear 235, and a second output gear 236. In actual application, some rotating shafts are also installed in conjunction with the above gears, namely, the driving gear rotating shaft 102, the reduction gear 232 rotating shaft, the first transmission gear rotating shaft 104, the second transmission gear 234 rotating shaft, and the first output gear 235 rotating shaft.

[0037] To further enhance torque and clutch effect, this embodiment also includes a friction plate 4, which is positioned between the reduction gear set 23 and the motor 22. In practical design, the purpose of the transmission connection between the reduction gear set 23 and the motor 22 is primarily to increase torque output. To further increase torque, a friction disc is also provided between the motor 22 and the reduction gear set 23, located on the drive gear rotating shaft 102. In practical application, this design effectively increases torque. By changing the weight and size of the friction disc, the torque of the drive gear rotating shaft 102 is altered, thereby increasing the torque of the drive shaft 24 after meshing transmission, ultimately changing the torque of the rotating shaft 33 that drives the shoe upper 3 to rotate. Simultaneously, the friction disc 4 also achieves a clutch-like clutch effect. The friction plate 4 abuts against the friction disc surface on the output shaft of the motor 22, and by changing the friction plate 4, the friction between the friction plate 4 and the drive housing 21 surface changes. Therefore, a clutch effect is achieved, providing overload protection for the motor.

[0038] In this embodiment, to achieve a further force-enhancing effect, a torque limiting component 5 is also included; the torque limiting component 5 is installed inside the reduction gear set 23; the torque limiting component 5 includes a torque transmission rod 51 and a limiting sleeve 52; and the limiting sleeve 52 is provided in two places, and is respectively installed on the reduction gear 232 and the first transmission gear 233; the two ends of the torque transmission rod 51 are respectively connected to the limiting sleeves 52 at the two locations. In practical applications, the purpose of this design is to increase torque. The torque transmission rod 51 is U-shaped, and the limiting sleeve 52 is hinged to the torque transmission rod 51 to achieve torque transmission. Simultaneously, in actual operation, when the drive gear rotating shaft 102 rotates with the motor 22, it drives the rotation of the reduction gear 232 rotating shaft, thereby causing the limiting sleeve 52 mounted on it to rotate, which in turn causes the torque transmission rod 51 to rotate. When the torque transmission rod 51 is near a horizontal position, it corresponds to the upper and lower shoe positions. At this time, the multi-link torque transmission mechanism formed by the limiting sleeve 52 and the torque transmission rod 51, relative to... When a "dead point" appears on the shaft, the torque transmission rod 51 provides the first limiting mechanism. Simultaneously, in case of overload, the limiting sleeve 52 hinged to it—specifically, the limiting sleeve 52 at the first transmission gear 233—will abut against the adjacent rotating shaft 104 of the first transmission gear, providing a second limiting protection. To further enhance protection, safeguarding the motor and preventing overtravel, the design also includes two limiting blocks 53 to increase the reliability of position locking. These limiting blocks 53 are bolted to the side plate of the gearbox and located on either side of the rotating shaft of the reduction gear 232, with their bottom surfaces fixedly connected to the bottom surface of the drive housing 21. This restricts the rotation of the reduction gear 232 to only 180 degrees, ultimately ensuring the rotating shaft 33 can rotate.

[0039] To ensure overall fixation, this embodiment also includes a fixing clamp 6. The fixing clamp 6 is provided in two locations, with one location detachably mounted on the fixing plate 1 and the other location detachably mounted on the drive housing 21. In practical applications, this design improves interchangeability and ensures interchangeability.

[0040] Furthermore, to enable detachable installation, in this embodiment, the fixing clamp 6 includes a clamping fastener 61 and a fixing bolt 62. Both the fixing plate 1 and the drive box 21 have at least one connecting screw hole seat 101. The fixing bolt 62 passes through the clamping fastener 61 and is threadedly connected to the connecting screw hole seat 101. The clamping fastener 61 has an abutment groove that abuts against the track. In actual design, the clamping fastener 61 can be fixedly installed on the track by rotating the fixing bolt 62, thereby achieving overall fixation of the device.

[0041] In this embodiment, a coupling 7 is also included. The coupling 71 includes a coupling 71 and a connecting shaft 72. Two connecting shafts 72 are provided, one connected to the drive shaft 24 and the other connected to the tilting shaft 33. The connecting shafts 72 are detachably mounted at both ends of the coupling 71. In actual design, this connection method can also be replaced by a hinged connection.

[0042] To further ensure the monitoring effect, this embodiment also includes a monitoring mechanism 8, which is used to monitor the working displacement state of the shoe loading device 3. In actual use, the monitoring mechanism 8 monitors the working displacement state of the shoe loading device 3 mainly to monitor the flipping effect of the shoe loading device 3; in actual design, the monitoring mechanism 8 includes a shoe position detection component 81, a torsion spring 82, and a shoe position indicator 83. In this design, the shoe position detection component 81 is equipped with at least one proximity sensor 811, and the shoe position indicator 83 is equipped with two detection points 831, which are spaced 90 degrees apart. The torsion spring 82 is installed in the flip shaft 33, and the shoe position indicator 83 is detachably installed on the flip shaft 33, located on the torsion spring 82, and abutting against it. The shoe position indicator 83 is fixedly connected to the flip shaft 33. When the flip shaft 33 rotates, the detection points 831 on the shoe position indicator 83 will rotate accordingly. At this time, the proximity sensor 811 will sense the distance and upload its rotation displacement to the background control system. Through the control system, the motor 22 is driven to rotate, realizing the automatic flipping of the device on the track, and finally realizing the automatic shoe loading and unloading of the anti-slip iron shoe 31 on the specified position. At the same time, the torsion spring 82 will achieve a pre-compensation effect on the shoe position indicator 83 that it abuts, and reduce the axial displacement of the shoe position indicator 83.

[0043] In this embodiment, the flipping component 32 includes a shoe support 321, a flipping plate 322, and a fixing block 323; the fixing block 323 has two locations, which are respectively installed through the flipping shaft 33; and the fixing block 323 is detachably and fixedly installed on the flipping plate 322, one end of the shoe support 321 is installed on the flipping plate 322, and the other end of the shoe support 321 is connected to the anti-slip shoe 31.

[0044] In summary, the anti-slip iron shoe device that can automatically attach the shoe is not only reasonably designed, but also enables automated operation and remote monitoring; it greatly reduces manual intervention and alleviates labor costs. Therefore, this device is suitable for industry promotion.
