[0058] In the related art, there is a technical problem that overloading and unbalanced loading of railway flat cars cannot be detected during operation. The embodiment of the present application provides a railway flat car and a railway vehicle, which can at least solve the technical problem that overloading and unbalanced loading of railway flat cars cannot be detected during operation to a certain extent.

[0059] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0060] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a railway flat car 100, including a car body 110 and a bogie 120 installed on the car body 110. The railway flat car 100 also includes a weight sensor 130. The weight sensor 130 is installed on the lower center plate 121 of the bogie 120 and is located below the upper center plate 111 of the car body 110. The weight sensor 130 has two weight detection points 130b. The two weight detection points 130b are arranged at intervals along the width direction of the car body 110 and are respectively located on both sides of the pin shaft 122 of the bogie 120.

[0061] The structures of the car body 110 and the bogie 120 are various and well known to those skilled in the art, and are not limited in this application.

[0062] The weight sensor 130 is fixedly mounted above the lower core plate 121, and the weight sensor 130 is located below the upper core plate 111, that is, the weight sensor 130 is located between the upper core plate 111 and the lower core plate 121. The weight sensor 130 can be fixedly mounted on the lower core plate 121 by bolt connection, clamping, etc.

[0063] The upper center plate 111 will press on the weight sensor 130, exerting a downward force on the weight sensor 130, thereby enabling the weight sensor 130 to monitor and detect the weight of the vehicle body 110 and the cargo thereon in real time.

[0064] The weight sensor 130 has two weight detection points 130b, that is, it can detect two weight values. Figure 2 As shown, two weight detection points 130b are arranged at intervals along the width direction of the car body 110, and are respectively located on both sides of the pin 122 of the bogie 120. After such a design, one of the weight detection points 130b detects the weight located on one side of the pin 122, and the other weight detection point 130b detects the weight located on the other side of the pin 122. By the magnitude relationship of the values ​​detected by the two weight detection points 130b, it can be determined whether the railway flat car 100 is overloaded in the width direction. By adding the values ​​of each weight detection point 130b on the railway flat car 100, the load of the railway flat car 100 can be obtained, and it can be determined whether the railway flat car 100 is overloaded.

[0065] After such design, the railway flat car is equipped with a weight sensor 130. During the operation of the railway flat car 100, the load of the railway flat car 100 can be detected in real time, and it is known whether the railway flat car 100 is overloaded in the width direction, so as to provide guidance for the subsequent work of the railway staff.

[0066] The railway flat car 100 may be provided with one bogie 120, or may be provided with two or more bogies 120, etc., which is not limited in this application. It should be noted that when the railway flat car 100 is provided with multiple bogies 120, a weight sensor 130 is installed on the lower center plate 121 of each bogie 120 of the railway flat car 100, and the values ​​of each weight detection point 130b of each weight sensor 130 are added up to the load of the railway flat car 100.

[0067] In some embodiments, the railway flat car 100 includes two bogies 120 and two weight sensors 130 . The two bogies 120 are arranged at intervals along the length direction of the car body 110 , and the two weight sensors 130 are arranged in a one-to-one correspondence with the two bogies 120 .

[0068] After such a design, the sum of the four weight values ​​detected by the four weight detection points 130b of the two weight sensors 130 is the load of the railway flat car 100. The sum of the two weight values ​​detected by the two weight detection points 130b of each weight sensor 130 is the load on both sides of the railway flat car 100 along the length direction, namely, the front load and the rear load. After such a design, it is also possible to judge whether the railway flat car 100 has an unbalanced load in the length direction by the size relationship between the front load and the rear load.

[0069] For ease of understanding, the following examples are given: along the forward direction of the railway flat car 100, the weight value detected by the weight detection point 130b on the left of the front weight sensor 130 is 21.56t, and the weight value detected by the weight detection point 130b on the right is also 21.56t; the weight value detected by the weight detection point 130b on the left of the rear weight sensor 130 is 22.23t, and the weight value detected by the weight detection point 130b on the right is 23.56t.

[0070] From the above data, we can know that: there is no overload in the front area of ​​the railway flat car 100 in the width direction 100; there is overload in the rear area of ​​the railway flat car 100 in the width direction 100; the front load of the railway flat car 100 is: 21.56+21.56=43.12t; the rear load is 22.23+23.56=45.79t; the front load and the rear load are inconsistent, and the railway flat car 100 is overloaded in the length direction; it can also be known that the total load of the railway flat car 100 is: 43.12+45.79=88.91t, and the railway flat car 100 is overloaded (the maximum load is 70t, 88.91t>70t).

[0071] like Figures 3 to 6 As shown, the railway flat car 100 also includes a center plate wear plate 140, which is arranged between the upper center plate 111 and the weight sensor 130, the upper end surface of the center plate wear plate 140 contacts the lower end of the upper center plate 111, and the lower end surface of the center plate wear plate 140 contacts the upper end surface of the weight sensor 130.

[0072] The core disk wear disk 140 is arranged below the upper core disk 111 and above the weight sensor 130. The upper core disk 111 contacts the core disk wear disk 140, squeezes the core disk wear disk 140, and the core disk wear disk 140 contacts the weight sensor 130, thereby transmitting the force of the upper core disk 111 to the weight sensor 130, so that the weight sensor 130 can detect the weight. The structure of the core disk wear disk 140 is known to those skilled in the art, and it can be supported by special oil-containing nylon. The core disk wear disk 140 is arranged between the upper core disk 111 and the weight sensor 130, which can avoid the upper core disk 111 from directly contacting the weight sensor 130, improve the load uniformity of the upper core disk 111, and increase the service life of the weight sensor 130.

[0073] In some embodiments, the lower center plate 121 has an upper center plate mounting groove 121a, and at least a portion of the upper center plate 111 is located in the upper center plate mounting groove 121a; a sensor mounting groove 121b is provided at the bottom of the upper center plate mounting groove 121a, and the weight sensor 130 is installed in the sensor mounting groove 121b, and at least a portion of the weight sensor 130 extends out of the sensor mounting groove 121b and is located in the upper center plate mounting groove 121a.

[0074] An upper core plate installation groove 121a is provided on the upper surface of the lower core plate 121, the notch of the upper core plate installation groove 121a is facing upward, the lower part of the upper core plate 111 is placed in the upper core plate installation groove 121a, and the upper core plate installation groove 121a limits the upper core plate 111. It should be noted that in the embodiment where the railway flat car 100 includes a core plate wear plate 140, the core plate wear plate 140 is also installed in the upper core plate installation groove 121a, and the upper core plate installation groove 121a also limits the core plate wear plate 140.

[0075] The bottom of the upper core plate installation groove 121a is provided with a sensor installation groove 121b, and the notch of the sensor installation groove 121b is also upward. The weight sensor 130 is fixedly installed in the sensor installation groove 121b, and the upper part of the weight sensor 130 extends out of the sensor installation groove 121b and is located in the upper core plate installation groove 121a, so that the upper core plate 111 or the core plate wear plate 140 can be pressed on the weight sensor 130, thereby enabling the weight sensor 130 to detect the weight.

[0076] In some embodiments, the weight sensor 130 has an avoidance hole 130 a for avoiding the pin shaft 122 , and the weight sensor 130 is sleeved outside the pin shaft 122 through the avoidance hole 130 a .

[0077] The pin shaft 122 is fixedly arranged on the bogie 120, and the pin shaft passes through the lower center plate 121, the upper center plate 111 and the center plate wear plate 140 at the same time. The weight sensor 130 is provided with an avoidance hole 130a to ensure that the pin shaft 122 can smoothly pass through the upper center plate 111 and the center plate wear plate 140 after passing through the weight sensor 130. The avoidance hole 130a of the weight sensor 130 is provided in the middle of the weight sensor 130.

[0078] In some embodiments, the weight sensor 130 has a lug 131 , and a limiting groove 121 c is formed on the inner wall of the sensor installation groove 121 b , and the lug 131 is located in the limiting groove 121 c .

[0079] The position-limiting weight sensor 130 is limitedly matched with the lower center plate 121 through the lug 131 to prevent the weight sensor 130 from rotating around the pin shaft 122 , thereby ensuring the stability of the position of the weight sensor 130 .

[0080] In some embodiments, the lug 131 is snap-fitted to the inner wall of the limiting groove 121 c so that the weight sensor 130 and the lower center plate 121 are fixedly connected.

[0081] like Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments, the railway flat car 100 also includes a positioning unit 150, a display unit 160 and a power supply unit 170; the positioning unit 150 is used for positioning; the display unit 160 is installed on the car body 110, electrically connected to the weight sensor 130, and used to display the weight values ​​detected by each weight detection point 130b of the weight sensor 130; the power supply unit 170 is installed on the car body 110, electrically connected to the weight sensor 130, the positioning unit 150 and the display unit 160, and used to supply power to the weight sensor 130, the positioning unit 150 and the display unit 160, and the positioning unit 150 is installed on the power supply unit 170.

[0082] The weight value detected by each weight detection point 130b is displayed in real time by the display unit 160, so that the user can understand the weight value detected by each weight detection point 130b in real time, and timely monitor the unbalanced load and overload of the railway flat car 100. The position of the car body 110 is located by the positioning unit 150, and the position of the railway flat car 100 can be detected in real time, which is convenient for the user to use the railway flat car 100. The power supply unit 170 can be a battery, etc., which is electrically connected to the weight sensor 130, the positioning unit 150 and the display unit 160 to provide power for the weight sensor 130, the positioning unit 150 and the display unit 160.

[0083] The positioning unit 150 is used to locate the position of the railway flat car 100. Its structure is diverse and well known to those skilled in the art. Users can directly purchase the positioning unit from the market, which is not limited in this application. In some embodiments, the positioning unit 150 uses the Beidou positioning system.

[0084] In some embodiments, the display unit 160 and the weight sensor 130, the display unit 160 and the power supply unit 170, the positioning unit 150 and the power supply unit 170, and the weight sensor 130 and the power supply unit 170 are all connected by wires. In some embodiments, a hose is provided on the outer cover of the wire to protect the wire and extend the service life of the wire.

[0086] When the railway flat car 100 passes a curve, that is, turns, the wires are easily rubbed against the lower center plate 121, which may cause line failure. In some embodiments, an aviation connector is used to connect the wires and the weight sensor 130, which can effectively prevent the wires from being worn. In addition, the aviation connector can realize a detachable connection between the weight sensor 130 and the wires, which can also facilitate the maintenance and repair of the weight sensor 130 in the future. The structure and installation method of the aviation connector are known to those skilled in the art and will not be described in detail here.
