Description

Technical Field

[0001] This utility model relates to bulk material loading and unloading equipment for railway vehicles, and in particular to a weighing device for a tipper platform. Background Technology

[0002] The weighing device on the tippler platform is used to read material weight data, assisting the tippler user in digitizing the unloading data. Currently, commonly used tippler weighing devices include dynamic and static weighing devices. Dynamic weighing devices typically require one set each at the tippler's entry and exit ends to weigh loaded and empty cars respectively. This type of device requires a concrete foundation, resulting in higher costs, and the weighing process occurs during car movement, limiting measurement accuracy. Static weighing devices are generally installed below the tippler's idlers, increasing the overall height of the tippler and requiring the weighing of both the tippler and the train car, further increasing the cost of the tippler foundation and weighing equipment. Therefore, developing a new type of weighing device for tippler platforms is essential. Summary of the Invention

[0003] The present invention aims to facilitate the measurement of the weight data of materials unloaded by a tippler, and provides a weighing device for a tippler platform.

[0004] The purpose of this utility model is achieved by the following technical solution: a weighing device for a tippler platform, including a weighing bracket (1), a transverse tie rod (2), a longitudinal tie rod (3), a sensor (4), a pressure plate (5), and a guard rail (6); the lower end of the weighing bracket (1) is engaged with the upper pressure head of the sensor (4), and the lower pressure head of the sensor (4) is placed on the tippler platform support; the weighing bracket (1) is hinged to the tippler platform through the transverse tie rod (2) and the longitudinal tie rod (3), which restricts the transverse and longitudinal displacement of the weighing bracket (1) relative to the tippler platform; the pressure plate (5) is closed on the tippler platform, which restricts the vertical displacement of the weighing bracket (1) during the tippler overturning process; the guard rail (6) is installed on the weighing bracket (1) to protect the vehicle from falling off the rail during the tippler overturning process; the spherical pressure head of the sensor (4) only bears the vertical force, and its measured data is accurate and complete.

[0005] The loaded train car is positioned on the tippler platform, ensuring that the front bogie of the car is on the front weighing device and the rear bogie is on the rear weighing device. The first weighing is performed to measure and record the weight of the car and the materials. Then the tippler performs the unloading operation. After the unloading is completed, the tippler returns to the 0 position and is weighed again to measure the weight of the car after unloading. The program will calculate the weight of the materials and store it in the database to complete the weight measurement of the unloaded materials.

[0006] Compared with the prior art, the present invention has the following advantages: 1. Simple structure and easy maintenance; 2. The weighing platform has a limit device, so the weighing device does not move during the tipper unloading process; 3. The sensor installation structure is reasonable, and the measured data is accurate and complete. Attached Figure Description

[0007] Figure 1 This is a top view of the weighing device on the tippler platform; Figure 2 This is the main view of the weighing device on the tipper platform; Figure 3 This is a side view structural diagram of a specific embodiment of the present utility model; Figure 4 This is a top view of a specific embodiment of the present invention.

[0008] In the diagram: 1. Weighing bracket; 2. Horizontal tie rod; 3. Longitudinal tie rod; 4. Sensor; 5. Pressure plate; 6. Guard rail. Detailed Implementation

[0009] like Figure 1-4 The diagram shows a weighing device for a tippler platform, comprising: a weighing bracket 1; a transverse tie rod 2; a longitudinal tie rod 3; a sensor 4; a pressure plate 5; and a guard rail 6. The weighing bracket 1 has mounting holes for the transverse tie rod 2 on both sides for hinged connection. The weighing bracket 1 also has mounting holes for the longitudinal tie rod 3 at its front and rear ends for hinged connection. The weighing bracket 1 restricts its lateral and longitudinal displacement relative to the tippler platform via the transverse tie rods 2 and 3. The weighing bracket 1 is fixed by the pressure plate 5, which is bolted to the tippler platform. The lower surface of the pressure plate 5 contacts the upper surface of the weighing bracket 1, restricting its vertical displacement. The guard rail 6 is a U-shaped structure fixed to the inside of the weighing bracket 1 to protect the vehicle bogie from derailing during tippler unloading. The upper pressure head of sensor 4 is engaged with the weighing bracket 1, and the lower pressure head of sensor 4 is in contact with the tipper platform support. The spherical pressure head of sensor (4) only bears the force in the vertical direction, and its measured data is accurate and complete.

[0010] The working principle is described in detail as follows: Loaded car weighing stage: When the train car enters the tippler platform, the four wheels of the front bogie rest on the weighing bracket 1 of the front weighing device, and the four wheels of the rear bogie rest on the weighing bracket 1 of the rear weighing device. At this time, the vertical pressure of the wheels is transmitted to the sensor 4 through the weighing bracket 1. The sensor 4 converts the pressure into an electrical signal, which is then recorded as the loaded car weight data by the data acquisition system. Under the combined action of the transverse tie rod 2, the longitudinal tie rod 3, and the pressure plate 5, the weighing bracket 1 only bears the force in the vertical direction, ensuring measurement accuracy.

[0011] During the unloading operation: When the tippler is unloading, the transverse tie rod 2, the longitudinal tie rod 3, and the pressure plate 5 together restrict the displacement of the weighing support 1 on the tippler platform, ensuring that the weighing device remains stable. The guard rail 6 protects the vehicle bogie from derailment during the tippler unloading process, preventing accidents from occurring during the unloading process.

[0012] Empty car weighing stage: After the tippler completes the unloading operation, it returns to position 0, weighs again, and records the empty car weight data. At this point, the car body on the tippler platform is empty, leaving only the weight of the car body itself.

[0013] Material weight calculation stage: The system automatically calculates the material weight (loaded vehicle weight - empty vehicle weight) and stores it in the database, completing the weight measurement of unloaded materials. The calculation process can be automatically completed by the PLC control system without manual intervention, improving work efficiency and data accuracy.

[0014] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
