Description

Technical Field

[0001] The present application relates to the technical field of railway vehicle anti-slipping, and in particular to a fastening device and a vehicle anti-slipping system. Background Art

[0002] In railway shunting operations, anti-slipping of vehicles is a crucial part of railway traffic safety. When a train is parked on the rails, it is easy for it to slip due to gravity, track slope, and strong winds. The train itself has a large mass, and the inertia generated when it slips is large. Once the train slips, it is difficult to brake it, which can easily cause a certain degree of danger.

[0003] The anti-skid fastener is an important tool to prevent vehicles parked on the railway from skidding. The principle is to use the hook on the fastener to hook the brake chain of the manual brake at the bottom of the vehicle, and hang the card at the tail of the fastener on the card on the manual brake at the rear of the train. After the two ends are hooked, the screw of the fastener is turned by the crank to apply tension to the fastener to tighten the brake chain, so that the brake shoe and the wheel tread rub to generate braking force.

[0004] Currently, the existing anti-skid fasteners cannot monitor the chain tension value of the manual brake in real time, and there is no scientific and well-founded method to judge whether the anti-skid operation performed by the on-site operator meets the axis tension requirements of the national standard. It can only be judged based on the subjective experience of the operator.

[0030] The technical solution of the present application will be described below in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1 , Figure 2 The present application provides a fastening device 1, which can be used in the anti-skid work of railway transportation vehicles, and is used to perform anti-skid braking on the vehicles. The fastening device 1 includes: a hook 100, a transmission member 200, a mounting seat 300, a card box 400, a fastening tension detection member 500, and a control module 600; wherein, one end of the transmission member 200 is rotatably connected to the hook 100, the mounting seat 300 is sleeved on the transmission member 200, the card box 400 is rotatably connected to the mounting seat 300, the fastening tension detection member 500 is sleeved on the transmission member 200 and connected to the mounting seat 300, the control module 600 is arranged in the card box 400, and the fastening tension detection member 500 is electrically connected to the control module 600.

[0032] In this embodiment, the hook 100 of the fastening device 1 is hooked on the manual brake chain at the bottom of the train, and the train body is fixed by the card box 400, and the transmission member 200 is fixed by a special tool. The special tool is shaken by manpower or mechanically assisted to drive the transmission member 200 on the fastening device 1 to rotate, and the mounting seat 300 and the fastening tension detection member 500 are fixed to the train body through the card box 400 and remain relatively motionless. The transmission member 200 moves axially relative to the mounting seat 300, the card box 400 and the fastening tension detection member 500, thereby pulling the hook 100 to tighten the brake chain to achieve anti-slip braking. When the hook 100 begins to be stressed to tighten the brake chain, the fastening tension detection member 500 can detect slight deformation, and then generate changes in the tension value signal. As the brake chain is pulled tighter, the tension value signal changes more. Therefore, the change in the tension value on the manual brake chain can be monitored in real time by the fastening tension detection member 500.

[0033] The tightening tension detection member 500 transmits the tension value signal collected in real time to the control module 600, and the control module 600 receives the tension value signal and determines whether the current tension value signal reaches the deployment setting value. According to the judgment result, the control module 600 gives a corresponding control instruction, which is convenient for the on-site operator to make a more intuitive judgment on the deployment requirement. It should be noted here that the tension value signal collected by the tightening tension detection member 500 can be regarded as the tension value on the brake chain of the manual brake.

[0034] The hook 100 is used to realize the hooking function, so the hook 100 needs to have certain strength and stability. Optionally, the hook 100 includes: a hook 110 and a thrust bearing 120, one end of the hook 110 is connected to the thrust bearing 120, and the thrust bearing 120 is rotatably connected to the transmission member 200.

[0035] In this embodiment, the hook 110 is used to hook the manual brake chain at the bottom of the train, and the thrust bearing 120 is used to connect the transmission member 200, so that the thrust bearing 120 and the transmission member 200 can be rotated more labor-saving and convenient to use.

[0036] Optionally, the transmission member 200 can be a screw rod, one end of the thrust bearing 120 is rotatably connected to the screw rod, and the other end of the thrust bearing 120 is fixedly connected to the hook 110. Therefore, when the screw rod rotates, the hook 110 will not rotate with the rotation of the screw rod when hooking the manual brake chain at the bottom of the train, thereby preventing the brake chain from being twisted together.

[0037] Furthermore, when the transmission member 200 is a screw rod, the mounting seat 300 can be a nut seat, and when the nut seat is sleeved on the screw rod, it is threadedly connected with the screw rod. In one embodiment, the mounting seat 300 and the transmission member 200 are both engaged with T-shaped threads of the same structure. The transmission member 200 and the mounting seat 300 are connected with T-shaped threads, so that it is more time-saving and labor-saving when rotating the transmission member, and it is convenient to use.

[0038] Furthermore, the card box 400 is rotatably connected to the mounting base 300. The rotatable connection includes, but is not limited to, a hinge connection, a pin connection, a gear connection, a universal joint connection, and the like.

[0039] In order to limit the card box 400 from rotating too much on the mounting seat 300, a limiter may be provided to limit the card box 400. In one embodiment, the limiter is provided on the card box 400 to limit the card box 400 to rotate 180 degrees. In another embodiment, a limiter rod 510 may be provided at both sides of the tightening tension detection member 500 sleeved on the transmission member 200. When the card box 400 rotates relative to the mounting seat 300, the limiter rod 510 on the tightening tension detection member 500 may further limit the rotation angle of the card box 400.

[0040] In order to improve the stability of the fastening device 1 when performing anti-skid braking of the vehicle, the card box 400 can be hooked or clamped on the car body while the hook portion 100 hooks the manual brake chain at the bottom of the train. Optionally, at least one clamping position 410 is provided on the card box 400, and the clamping position 410 is used to clamp and fix with the object to be clamped. Among them, the object to be clamped is the train body or an object such as a plate, a rod, etc. on the body that can provide a clamping position for the card box 400. The clamping position 410 includes but is not limited to a structure with a accommodating function such as a groove or a pit.

[0041] In this embodiment, by setting the engaging position 410 on the card box 400, the card box 400 is easier to be hooked on the train body when the hook 110 is hooked on the manual brake chain at the bottom of the train. It can be understood that when the special tool is used to shake and fix the transmission member 200, the card box 400 can be regarded as the supporting point of the fastening device 1, providing a fixed supporting force for the transmission member 200 when rotating, so that it is more labor-saving when shaking the transmission member 200, and further improving the stability of the fastening device 1 when performing anti-slip braking. It should be noted that when the transmission member 200 is shaken and the transmission member 200 rotates, since the card box 400 is hung on the train body, it is equivalent to being fixed. According to the principle of relative motion of objects, the transmission member 200 is moving relative to the card box 400 and the fastening tension detection member 500 connected thereto, so the movement of the transmission member 200 pulls the hook 100 to tighten the chain, thereby realizing the anti-slip braking of the vehicle.

[0042] In an operation process, the hook portion 100 of the fastening device 1 is hooked on the manual brake chain at the bottom of the train, and the engaging portion 410 on the card box 400 is hooked on the train body. After the fastening device 1 is installed and fixed, a special tool is used to shake the transmission member 200 to rotate the transmission member 200. At this time, the mounting seat 300 and the transmission member 200 rotate along the axial direction of the transmission member 200 due to the threaded engagement. In this way, the distance between the hook portion 100 and the card box 400 can be directly controlled. Therefore, the manual brake chain can be gradually tightened by this method, so that the train is not easy to slip when it stops on the track.

[0043] Similarly, when it is necessary to release the vehicle's anti-skid brake, a special tool can be used to shake the transmission member 200 in the opposite direction to make the transmission member 200 rotate in the opposite direction, and the manual brake chain gradually loosens. At this time, the tension value signal on the tightening tension detection member 500 is constantly decreasing until the tension value signal is displayed as less than the set threshold or equal to zero. At this time, the operator can remove the hook 100 and the card box 400 to remove the fastening device 1 and release the anti-skid brake of the vehicle.

[0044] For further information, please refer to Figure 1 , Figure 2 as well as Figure 3 The card box 400 includes a card plate 420, a top plate 430, a front cover plate 440 and a rear cover plate 450 which are symmetrically arranged; the front cover plate 440 and the rear cover plate 450 are arranged opposite to each other and are respectively connected to the card plate 420, and the top plate 430 is respectively connected to the front cover plate 440, the card plate 420 and the rear cover plate 450.

[0045] Compared with the structure of the card box 400 in the prior art, the size of the card plate 420 in this embodiment is enlarged. The increase in the size of the card plate 420 can, on the one hand, increase the clamping area between the clamping position 410 on the card box 400 and the train body, thereby improving the stability of the clamping; on the other hand, the internal accommodation space of the card box 400 is increased, which facilitates the reasonable arrangement of more electronic components.

[0046] Optionally, the card plate 420, the top plate 430, the front cover plate 440 and the rear cover plate 450 are integrally formed by a milling machine. In this embodiment, the card box 400 is integrally formed by a milling machine, which is convenient for processing and manufacturing.

[0047] Furthermore, pins 310 are fixed to both sides of the mounting seat 300, and the clamping plate 420 is rotatably connected to the pins 310. In this embodiment, the clamping plate 420 and the mounting seat 300 are connected in a pin connection manner, which has a simpler structure.

[0048] Since the tightening tension detection member 500 is sleeved on the transmission member 200 and is directly fixedly connected to the mounting seat 300, even if the card box 400 on the mounting seat 300 is damaged, the card box 400 can be directly removed and replaced with a new card box 400 without removing the tightening tension detection member 500, which is convenient for removal and replacement and reduces maintenance costs. If the transmission member 200 is worn, the transmission member 200 can be directly replaced, which has lower maintenance costs and is more convenient to replace.

[0049] As mentioned above, the tightening tension detection member 500 transmits the real-time collected tension value signal to the control module 600, and the control module 600 receives the tension value signal and determines whether the current tension value signal reaches the arming setting value. In addition, the control module 600 can also determine the disarming setting value or the warning setting value by receiving the tension value signal.

[0050] It can be understood that the arming setting value is the axis tension value that complies with the national standard when the fastening device 1 is used to perform anti-skid braking on the vehicle; the disarming setting value is the axis tension value that complies with the national standard when the fastening device 1 is used to release the anti-skid braking on the vehicle. The warning setting value is the axis tension value corresponding to the warning prompt when the fastening device 1 is used to perform anti-skid braking on the vehicle or release the anti-skid braking of the vehicle.

[0051] Among them, the arming setting value and the disarming setting value can be set according to the operation requirements or national standards. In this embodiment, the arming setting value can be set to an axis tension of 5-8kN according to the national standard for vehicle anti-skid operations. The disarming setting value can be set to an axis tension of less than 0.5kN according to the national standard for vehicle anti-skid operations. The warning setting value can be set according to the on-site operation requirements. For example, the warning setting value of the arming setting value is set to 5kN; the warning setting value of the disarming setting value is 0.5kN. The axis tension that the fastening device as a whole can withstand should be no less than 10-14.8KN according to the national vehicle standard requirements for fastening devices.

[0052] For further information, please refer to Figure 4 The card box 400 is also provided with a communication module 700, and the communication module 700 communicates wirelessly with a host computer. The host computer described here can be a monitoring center of a network inside a railway.

[0053] When the tension value exceeds the arming setting value, disarming setting value or warning setting value, the arming information, disarming information or warning information of the fastening device 1 can be sent to the host computer through the communication module 700, and the host computer can issue a corresponding indication signal according to the arming information, disarming information or warning information.

[0054] At present, the wireless network inside the train station and the railway is fully covered. Therefore, the deployment information, disarming information, warning information, etc. of the fastening device 1 can be timely transmitted to the monitoring center of the network inside the railway through the communication module 700, so that the monitoring center of the network inside the railway can conduct real-time monitoring and grasp the use status of the fastening device 1. Therefore, in this embodiment, the status information of the fastening device 1 is transmitted in real time through the communication module 700, the anti-slip status of the fastening device 1 is monitored, and remote monitoring is realized.

[0055] Optionally, the communication module 700 may include a communication unit and an antenna. In one embodiment, the communication module 700 uses a LoRa communication unit. In other embodiments, the communication module 700 uses one of the LoRa Internet of Things frequency bands, including but not limited to the 230Mhz-890Mhz frequency band.

[0056] During the railway operation, multiple on-site operators are required to perform vehicle anti-skid braking or release anti-skid braking operations on multiple trains of different train numbers. In order to further improve the railway operation efficiency, in this embodiment, a radio frequency card module 800 is set in the card box 400 of the fastening device 1, and the radio frequency card module 800 is electrically connected to the control module 600. The radio frequency card module 800 can timely obtain basic information such as operator information, operation information, corresponding track number information, train number information, etc., so as to realize the positioning information acquisition of the fastening device and the operator information acquisition. Then, the above basic information is sent to the host computer through the communication module 700. The host computer accurately grasps the corresponding use status of each fastening device 1 and the corresponding deployment and disarming operator information according to the deployment information, disarming information or warning information, as well as the basic information collected by the radio frequency card module 800.

[0057] During an operation, after the on-site operator installs the fastening device 1, he performs a slipping brake operation on the vehicle. Since each operator is equipped with an operation recorder, the operator's information is bound to the operation recorder. The operator inputs the relevant anti-slip vehicle information through the operation recorder App, and transmits it to the fastening device 1 through the radio frequency card module 800. The fastening device 1 then transmits the personnel information and the anti-slip vehicle information to the host computer through the communication module 700. The host computer can realize real-time monitoring of the fastening device 1 during use based on the above information.

[0058] Furthermore, in order to facilitate the on-site operators to grasp the deployment information, disarming information and warning information in time, the fastening device 1 further includes: an indication module 900, which is electrically connected to the control module 600; the fastening tension detection member 500 transmits the collected tension signal to the control module 600, and the control module 600 determines that when the tension signal reaches the deployment setting value, it sends an indication signal, and the indication module 900 is used to receive the indication signal and send indication information.

[0059] The control module 600 receives the tension signal collected by the tightening tension detection component 500, and determines whether the tension value reaches the arming setting value, the disarming setting value or the warning setting value. When the tension value reaches the arming setting value, the disarming setting value or the warning setting value, the control module 600 sends a control instruction to the indication module 900, and the indication module 900 sends an indication signal to remind the operator. At the same time, the arming information, disarming information and warning information are sent to the host computer through the communication module 700 to realize the monitoring of the intelligent fastening device 1 during use.

[0060] Optionally, the indication module 900 includes: an indicator light 910. The indicator light 910 is used to remind the on-site operator that when operating the fastening device 1, when the fastening tension detection member 500 detects that the tension value reaches the required arming setting value, disarming setting value or warning setting value, the control module 600 issues a control instruction to the indicator light 910 of the indication module 900 according to the judgment result, and helps the operator to judge the use status of the fastening device 1 according to the lighting of the indicator light.

[0061] In one embodiment, the indicator light 910 is an LED lamp bead.

[0062] Therefore, in order to facilitate the operator to see the lighting state of the indicator light 910, optionally, at least one surface of the card box 400 is a transparent window, and the indicator light 910 can be installed at the transparent window of the card box 400. Exemplarily, the rear cover 450 is set as a transparent window, the control module 600 can be installed at the rear cover 450, and the indicator light 910 can be installed on the control module 600, so that the operator can see the indicator light 910 through the rear cover 450, so as to judge whether the arming setting value, the disarming setting value, and the warning setting value are reached during the use of the fastening device 1.

[0063] Furthermore, the indication module 900 may also include: a buzzer 920. In one embodiment, the buzzer 920 may be installed together with the indicator light 910 at the transparent window of the card box 400, that is, simultaneously installed at the rear cover plate 450. When the fastening device 1 is in use, the fastening tension detection member 500 detects that the tension value reaches the required arming setting value, disarming setting value or warning setting value, and the control module 600 issues a control instruction to the indication module 900 according to the judgment result. At this time, the indicator light 910 lights up, and at the same time, the buzzer 920 starts to sound an alarm to remind the on-site operator.

[0064] In another embodiment, the buzzer 920 can be set separately. When the fastening device 1 is used and the required arming setting value, disarming setting value, and warning setting value are reached, the control module 600 issues a control instruction to the buzzer 920 of the indication module 900 according to the judgment result, and the buzzer 920 starts to sound an alarm to remind the on-site operator.

[0065] During an operation, the on-site operator uses the fastening device 1 to perform anti-skid braking on the vehicle. The operator inputs relevant anti-skid vehicle information through the operation recorder App. The radio frequency card module 800 on the fastening device 1 records and reads basic information such as on-site operator information (including name and other identity information), operation time, track number information, train number information, etc.; the radio frequency card module 800 transmits the read on-site operator information, operation time, track number information, train number information, etc. operation information to the communication module 700, and the communication module 700 transmits it to the host computer.

[0066] After completing the information reading, the operator installs the fastening device 1, hooks the hook 100 of the fastening device 1 to the manual brake chain at the bottom of the train, and uses the card box 400 to fix the train body, uses a special tool to fix the transmission member 200, and shakes the special tool to drive the transmission member 200 of the fastening device 1 to rotate, and the mounting seat 300 drives the fastening tension detection member 500 to move along the axial direction of the transmission member 200, thereby tightening the brake chain through the hook 100 to achieve anti-slip braking. When the transmission member 200 rotates the hook 100 and begins to tighten the brake chain, the fastening tension detection member 500 can detect slight deformations, thereby generating changes in the tension value signal. As the brake chain is tightened, the tension value signal changes more. In the process of the transmission member 200 rotating the hook 100 to tighten the brake chain, the fastening tension detection member 500 detects changes in the tension value signal in real time.

[0067] When the tension value signal continues to increase and the currently detected tension value is greater than 5kN, that is, reaches the deployment setting value range of 5-8kN, the control module 600 sends a control instruction to the indication module 900 based on the judgment result, the indicator light 910 lights up, and at the same time, the buzzer 920 starts to sound an alarm to remind the on-site operator.

[0068] After the indication module 900 sends an indication signal, it reminds the operator that the communication module 700 can send the real-time tension value of 5kN detected by the current tightening tension detection member 500 as the deployment information of the tightening device 1 to the host computer, and at the same time, the radio frequency card module 800 transmits the basic information such as the on-site operator information, operation time, track number information, train number information, etc. read to the host computer of the monitoring center of the railway internal network. After the operation is completed, the on-site operator and the monitoring center talk to each other to check whether the anti-slip information is correct. After confirmation, the anti-slip operation is completed.

[0069] After the anti-skid operation is completed, there is no need for manual on-site inspection. The fastening device 1 will regularly monitor the axial tension of its brake chain and regularly send the corresponding tension value data to the host computer monitoring center. Once the tension value is lower than the minimum warning setting value of 5kN set for deployment, abnormal information will appear, and the abnormal information will be transmitted to the host computer monitoring center through the communication module 700 for voice alarm. The monitoring center can notify the on-site operators to conduct inspections based on the alarm information.

[0070] Similarly, when it is necessary to release the vehicle's anti-skid brake, use a special tool to shake the transmission member 200 in the opposite direction to make the transmission member 200 rotate in the opposite direction, and the manual brake chain gradually loosens. At this time, the tension value signal on the tightening tension detection member 500 is constantly decreasing. When the tension value signal decreases and reaches the disarming setting value (assuming that the current detected tension value is 0.49kN), the control module 600 sends a control instruction to the indication module 900 based on the judgment result, and the indicator light 910 lights up. At the same time, the buzzer 920 starts to sound an alarm to remind the on-site operator. The communication module 700 transmits the real-time tension value of 0.49 kN detected by the current tightening tension detection component 500 as the disarming information of the fastening device 1, as well as the basic information such as the on-site operator information, operation time, track number information, train number information, etc. read by the radio frequency card module 800 to the host computer of the monitoring center of the internal railway network. After receiving the disarming information, the host computer can give an instruction information to the on-site operator. According to the instruction signal, the on-site operator can promptly know that the train has released the vehicle anti-skid brake and can wait for the driving instruction.

[0071] Furthermore, a power supply is also provided in the card box 400, and the power supply is used to continuously supply power to various electrical components, such as supplying power to the control module 600, the communication module 700, the radio frequency card module 800, and the indication module 900.

[0072] In summary, the fastening device 1 of the present application has added a fastening tension detection member 500. By real-time detection of the tension value during the operation of the fastening device 1, the operator can obtain the corresponding tension size of the fastening device 1 in real time during the deployment and disarming operation state, and more intuitively judge whether the deployment and disarming requirements are met. The communication module 700 is used to realize wireless communication between the fastening device 1 and the railway station monitoring center, so that the operator of the monitoring center can obtain the use status of the fastening device 1 in time, making the on-site deployment and disarming operations more convenient. The radio frequency card module 800 is used to realize the positioning tracking and real-time monitoring of the use status of the fastening device 1.

[0073] Furthermore, the embodiment of the present application also provides a vehicle anti-slip system, including the fastening device 1 described in the embodiment of the present application. Optionally, the fastening device 1 can also cooperate with an anti-slip iron shoe to achieve anti-slip braking of the vehicle.
