[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0028] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.
[0029] like Figure 1 and Figure 5 As shown, according to an embodiment of the utility model, a parking anti-slip device braking force monitoring device 100 is provided, and the parking anti-slip device braking force monitoring device 100 includes an inner support mechanism 110, a brake drive mechanism 120, a brake force detection component 130 and a control system 140. The inner support mechanism 110 is connected to the brake rail 170, and the brake drive mechanism 120 is connected to the inner support mechanism 110. The brake drive mechanism 120 is suitable for driving the inner support mechanism 110 to drive the brake rail 170 to move to achieve braking; the brake force detection component 130 is arranged on the inner support mechanism 110, and the brake force detection component 130 is suitable for detecting the braking force generated by the inner support mechanism 110 during the movement process and generating a braking force signal. The control system 140 is communicatively connected with the brake force detection component 130, and the control system 140 controls the braking force within a safe range according to the brake force signal.
[0030] In this embodiment, the brake rail 170 cooperates with the basic rail of the railway line, and a method is adopted in which the brake rails 170 on both sides of the parking anti-slip device braking force monitoring device 100 are simultaneously supported inwardly to act on the inner side of the railway locomotive vehicle wheel, and friction is used to prevent the railway locomotive vehicle that stops or moves at a low speed on the basic rail from slipping. According to the needs of railway transportation organization, when the working state is braking, the brake drive mechanism 120 drives the inner support mechanism 110, and the brake rail 170 is supported inwardly on both sides and rises upward, so that the action surface of the brake rail 170 can fully contact the inner side of the railway locomotive vehicle wheel to meet the braking needs. When the non-working state is relief, the brake rail 170 shrinks inwardly and drops downward, and each component is outside the specified limit, thereby ensuring the needs of various types of railway locomotive vehicles to pass on the basic rail.
[0031] During braking, the braking force is usually measured and calculated by staff on site, and whether measures need to be taken are evaluated based on the measurement results. This method not only wastes manpower, but also causes loss in the working efficiency of the locomotive. Therefore, the braking force generated by the inner support mechanism 110 during the operation is detected by the braking force detection component 130 and a braking force signal is generated. The braking force signal transmits data to the control system 140 via the 485 communication method. The control system 140 controls the braking force within a safe range to ensure that the vehicle can stay stably in place, thereby effectively preventing safety accidents caused by locomotive sliding or slipping.
[0032] In another embodiment, Figure 2 As shown, the braking force detection component 130 includes an elastic member 131 and a pressure detection module 132. The elastic member 131 has an elastic deformation direction. The elastic member 131 is connected to the internal support mechanism 110 at one end of the elastic deformation direction. The pressure detection module 132 abuts against the elastic member 131 at the other end of the elastic deformation direction. The braking force signal is a pressure signal detected by the pressure detection module 132.
[0033] In this embodiment, an elastic member 131 is installed on the inner support mechanism 110, and the elastic member 131 can store energy. A high-precision pressure detection module 132 is installed at one end of the elastic deformation direction of the elastic member 131. When braking, the brake drive mechanism 120 drives the inner support mechanism 110 to open the elastic members 131, brake arms 180 and brake rails 170 at both ends. At the same time, the brake arms 180 and brake rails 170 move along the grooves of the lifting and positioning frame 190. After braking, the brake drive mechanism 120 stops rotating. At this time, the elastic members 131 at both ends are supported to the maximum position, and the pressure felt by the pressure detection module 132 is the braking force of the parking anti-slip device.
[0034] The pressure detection module 132 monitors the braking force output of the vehicle in real time, and converts the braking force data into electrical signals and transmits them to the control system 140. The control system 140 receives the braking force data transmitted by the pressure detection module 132, and determines whether the current braking force is sufficient based on a preset braking force threshold.
[0035] Among them, the control system 140 receives the braking force data transmitted by the pressure detection module 132, and performs real-time analysis and processing. The control system 140 is provided with a braking force threshold, which can be a specific value or a range value. According to the preset braking force threshold, the control system 140 can determine whether the current braking force is sufficient and take corresponding measures. For example, if the detected braking force data is greater than the braking force threshold, the control system 140 can control the braking drive mechanism 120 to decelerate, and if the detected braking force data is less than the braking force threshold, the braking drive mechanism 120 is controlled to increase the braking force until the detected braking force is equal to the braking force threshold or falls within the interval range of the braking force threshold, and then the braking is stopped.
[0036] The data collected by the pressure detection module 132 is converted, amplified, output processed and analyzed so that the system can accurately determine the braking force stability of the parking device.
[0037] The pressure signal detected by the pressure detection module 132 is a braking force signal, which can monitor the braking force output of the vehicle braking system in real time. The pressure detection module 132 converts the braking force data into an electrical signal and transmits it to the control system 140 for processing.
[0038] The pressure data detected by the pressure detection module 132 is converted and amplified, and can be transmitted to the management system in real time through the Internet of Things technology for staff to make judgments.
[0039] In another embodiment, the elastic member 131 is a disc spring, and the disc spring is a disc-shaped spring, which can better store energy.
[0040] In another embodiment, the pressure detection module 132 includes a pressure sensor. By detecting the pressure from the elastic member 131 through the pressure sensor, the detection accuracy can be improved.
[0041] In another embodiment, the pressure detection module 132 further includes a support frame, the support frame is fixed on the rail, and the pressure sensor is arranged on the support frame. The pressure detection module 132 is arranged on the support frame so that the pressure sensor can be fixed, the disc spring is compressed, and the position of the pressure sensor is fixed, so that the pressure from the disc spring can be detected more accurately.
[0042] In another embodiment, a parking guard braking force monitoring device 100 further includes an alarm system 160, which is communicatively connected to a control system 140. If the braking force is within an unsafe range, the control system 140 controls the alarm system 160 to send an alarm signal.
[0043] The staff can judge and prevent the braking force of the parking anti-skid device braking force monitoring device 100 according to the transmitted data. When the braking force is insufficient, the control system 140 will trigger the alarm system 160, for example, it can send an alarm signal to the driver, so that the staff can check in time and take corresponding measures.
[0044] In another embodiment, the internal support mechanism 110 includes a screw 111, a first nut 112, a second nut 113 and a connecting rod 114, the screw 111 is connected to the brake drive mechanism 120, the first nut 112 is threadedly connected to the screw 111, the second nut 113 is threadedly connected to the screw 111, the second nut 113 and the first nut 112 are spaced apart from each other, and the connecting rod 114 is rotatably connected to the first nut 112 and the second nut 113 respectively; wherein, the elastic member 131 is connected to the connecting rod 114.
[0045] In this embodiment, the brake drive mechanism 120 drives the lead screw 111 to rotate, and the first nut 112 and the second nut 113 move toward each other, thereby driving the connecting rod 114 to move. The first nut 112 and the second nut 113 are hinged to the connecting rod 114 respectively.
[0046] In another embodiment, the connecting rod 114 includes a first rod body 1141 and a second rod body 1142, one end of the first rod body 1141 is rotatably connected to the first nut 112, one end of the second rod body 1142 is rotatably connected to the second nut 113, and the connecting block 1143 is connected to the first rod body 1141 and the second rod body 1142; wherein the elastic member 131 is connected to the connecting block 1143.
[0047] The connecting rod 114 includes two first rod bodies 1141 and two second rod bodies 1142, that is, the connecting rod 114 is a four-bar connecting rod 114 mechanism. The first nut 112 is symmetrically hinged to the two first rod bodies 1141, the second nut 113 is symmetrically hinged to the two second rod bodies 1142, and a set of structures connecting the first rod body 1141 and the second rod body 1142 are provided on opposite sides of the lead screw 111.

[0048] In another embodiment, the braking drive mechanism 120 includes a transmission rod 121, a clutch 122 and a reduction motor 123.

The clutch 122 has a power input end and a power output end, and the power output end is connected to the transmission rod 121; the reduction motor 123 has a power end, and the power end is connected to the power input end.
[0049] In this embodiment, the reduction motor 123 includes a driving motor 1232 and a reducer 1231. A high-precision pressure detection module 132 is installed at the disc spring of the brake arm 180. During the braking action, the driving motor 1232 and the output shaft of the reducer 1231 begin to rotate clockwise, and the transmission rod 121 and the two-way lead screw 111 nut mechanism are driven by the clutch 122 to move the nut inward, driving the connecting rod 114 to open the disc springs, brake arms 180 and brake rails 170 at both ends. At the same time, the brake arms 180 and brake rails 170 move along the grooves of the lifting and positioning frame 190. After the brake is in place, the motor stops rotating.

[0054] 1. Improve safety: A parking anti-slip brake force monitoring device 100 detects the pressure of the disc spring of the inner support structure in real time through the pressure detection module 132, so as to monitor the braking force of the vehicle in real time, ensuring that the vehicle can stay in place stably when parking, and preventing the vehicle from sliding or slipping due to insufficient braking force.
