[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0040] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] As Figure 1 and Figure 2 shown, the present utility model provides a bogie detection device for detecting the tensile resistance and load-bearing strength of the frame body 1 in the bogie. It includes a base 2, a first detection component 3, a second detection component 4, and a control unit.

[0042] Among them, the base 2 is fixed on the workshop floor, and the frame body 1 to be tested is placed above the base 2. The first detection component 3 includes a pressure loading device 31 for applying a vertical pressure to the frame body 1 and a pressure detection device 32. The pressure loading device 31 and the pressure detection device 32 are installed on the base 2. The second detection component 4 is arranged on both sides of the frame body 1 and has two groups. The structures of the two groups of second detection components 4 are the same, and both include a tensile force loading device 41 for applying a lateral tensile force to the frame body 1 and a tensile force detection device 42. The tensile force loading device 41 is installed on the base 1. The first detection component 3 and the second detection component 4 are electrically connected to the control unit.

[0043] In this way, a device can be used to realize the test of the tensile resistance and load-bearing strength of the frame body 1, which can not only simplify the device structure, reduce costs, but also improve the detection efficiency, thereby ensuring the safety of the rail vehicle during driving.

[0044] In this embodiment, the pressure-applying device 31 includes a horizontally disposed pressure plate 311 and a press 312 that applies vertical pressure to the pressure plate 311. The pressure plate 311 is a complete flat plate structure, its shape matching the horizontal projection of the frame body 1. Its width can be the same as or slightly wider than the width of the frame body 1, and its length is slightly shorter than the length of the frame body 1, avoiding the ends of the frame body 1 to facilitate connection between the frame body 1 and other components. Thus, by utilizing a complete pressure plate 311 as a whole to apply vertical force downwardly to the frame body 1, the pressure applied to the frame body 1 is evenly distributed across its upper surface, ensuring a uniform force distribution across the frame body 1 and more accurate test results.

[0045] In this embodiment, an inverted L-shaped mounting base 5 is preferably mounted on the base 2. The mounting base 5 is mounted on one side of the frame body 1. The bottom of the vertical portion 51 of the mounting base 5 is fixed to the base 2, and the press 312 is mounted on the horizontal portion 52 of the mounting base 5. The press 312 is preferably a hydraulic cylinder, which is vertically mounted on the horizontal portion 52 of the mounting base 5. The output shaft of the hydraulic cylinder vertically passes through the horizontal portion 52 of the mounting base 5 and connects to the pressing plate 311 below, so that the pressing plate 311 is directly above the frame body 1. The operation of the hydraulic cylinder is controlled by a control unit, thereby controlling the lifting and lowering of the lower pressing plate 311, thereby controlling the pressing plate 311 to press the frame body 1 downward.

[0046] The base 2 is used to provide a supporting platform with sufficient supporting capacity for the pressure loading device 31, and the press 312 can be installed directly above the frame body 1, so that the force application point of the press 312 is located on the center line of the frame body 1, ensuring accurate pressure detection.

[0047] In this embodiment, the pressure detection device 32 comprises a plurality of pressure sensors 321, which are evenly distributed and mounted on the upper surface of the base 2. Each of the pressure sensors 321 is electrically connected to the control unit. Furthermore, a bearing plate 33 is preferably mounted on top of the pressure sensors 321, and the frame body 1 is placed on the bearing plate 33.

[0048] In this embodiment, the load-bearing plate 33 is used to support the frame body 1, and the weight of the frame body 1 and the vertical pressure applied downward by the press 312 through the pressure plate 322 are transferred to the load-bearing plate 33, and then detected by several pressure sensors 321 under the load-bearing plate 33 to obtain the required pressure value.

[0049] Specifically, when the pressing plate 311 presses down on the frame body 1, the frame body 1 can press down on the pressure sensor 321 together with the load-bearing plate 33, so as to be able to detect in real time the downward pressure weight of the frame body 1 exerted by the pressing plate 311 and check whether the bearing strength of the frame body 1 meets the requirements. It should be noted that the downward pressure weight is the weight detected by the pressure sensor 321 minus the self-weights of the load-bearing plate 33 and the frame body 1. The greater the downward pressure weight that the frame body 1 can bear, the stronger the bearing strength of the frame body 1.

[0050] In this embodiment, it is further preferably that the load-bearing plate 33 is installed on the base 2 through a rotating mechanism (not shown in the figure). The rotating mechanism can be a bearing disc, so that it is convenient for the inspectors to adjust the position of the frame body 1 in the horizontal direction according to the actual situation on site. In this structure, it is ensured that the load-bearing plate 33 supports on the pressure sensor 321.

[0051] In this embodiment, preferably, the tension loading device 41 in the second detection assembly 4 includes a pulling rope 411 and a servo motor 412. The two ends of the pulling rope 411 are respectively connected to the frame body 1 and the servo motor 412. The servo motor 412 is fixedly installed on the motor base 413. The two motor bases 413 in the two groups of second detection assemblies 4 are symmetrically installed on the base 2 on both sides of the frame body 1.

[0052] An I-shaped pulley 414 is fixed on the output shaft of the servo motor 412, and the pulling rope 411 is connected to the I-shaped pulley 414. When the control unit controls the operation of the servo motor 412, it controls the I-shaped pulley 414 to rotate forward and backward, so as to be able to retract or release the pulling rope 411, and apply a pulling force to the frame body 1 when retracting the pulling rope.

[0053] In this embodiment, it is further preferably that a baffle 6 is installed between each motor base 413 and the frame body 1. The baffles 6 in the two groups of second detection assemblies 4 are symmetrically installed on the base 2. The frame body 1 is placed between the two baffles 6. A through hole 61 is opened on the baffle 6, and the pulling rope 411 passes through the through hole 61 on the baffle 6 and is connected to the frame body 1 and the servo motor 412. The setting of the baffle 6 can play a role in protecting the pulling rope 411 and the servo motor 412.

[0054] Such as Figure 2 and Figure 3As shown in the figure, in this embodiment, it is further preferably that a U-shaped buckle 43 is installed at the end of the pull rope 411. Through holes 431 are opened at both ends of the U-shaped buckle 43. A communication hole 11 is correspondingly opened at the end of the frame body 1. The U-shaped buckle 43 is snapped into the end of the frame body 1. A bolt 44 passes through the communication hole 11 of the frame body 1 and the through holes 431 at both ends of the U-shaped buckle 43. The upper and lower ends of the bolt 44 are tightened and fixed by nuts 45, realizing the fixed connection between the U-shaped buckle 43 and the frame body 1, and further connecting the pull rope 41 to the frame body 1. By simply disassembling and installing the bolt 44 and the nut 45, the disassembly and installation between the U-shaped buckle 43 and the frame body 1 can be controlled, and the operation is simple and convenient.

[0055] In this embodiment, the tensile force detection device 42 preferably adopts a tensile force sensor 421. The tensile force sensor 421 is installed on the pull rope 411. When the pull rope 411 is contracted to apply a tensile force to the frame body 1, the tensile force sensor 421 can detect the applied tensile force value at this time. Both tensile force sensors 421 are electrically connected to the control unit.

[0056] Specifically, when the servo motor 412 controls the contraction of the pull rope 411, a tensile force can be applied to both ends of the frame body 1. This tensile force can be detected by the tensile force sensor 421 in real time, so as to well detect whether the tensile resistance of the frame body 1 meets the requirements.

[0057] As Figure 4 As shown in the figure, in this embodiment, the control unit includes a controller 7. The controller 7 is connected to a power supply 8. The power supply is 220V commercial power from the outside. The controller 7 can be an existing technical device such as a computer that plays a control role. The tensile force sensor 421, the pressure sensor 321, the servo motor 412, and the press 312 are all electrically connected to the controller 7. The controller 7 uniformly controls the actions of the servo motor 412 and the press 312, and at the same time receives the tensile force value and the pressure value transmitted by the tensile force sensor 421 and the pressure sensor 321, and further calculates the maximum tensile force and the maximum downward pressure weight that the frame body 1 can bear according to the tensile force value and the pressure value, and then judges whether the tensile resistance and the bearing strength of the frame body 1 meet the design requirements.

[0058] The bogie detection device provided by the present utility model has the following advantages:

[0059] 1. It can use one device to realize the test of the tensile resistance and bearing strength of the frame body, which can not only simplify the device structure, reduce costs, but also improve the detection efficiency, so as to well detect the quality of the frame body and ensure the safety of the rail vehicle during driving.

[0060] 2. The device tests the bearing strength of the frame body by controlling the first detection component to apply a downward pressure on the frame body, and tests the tensile resistance ability of the frame body by controlling the second detection component to apply a tensile force on the frame body through the control unit, and the operation is safe and reliable.

[0061] 3. The device integrates the detection devices for tensile resistance and bearing strength on a base, which can greatly reduce the occupied space of the two detection devices.

[0062] The above are only the preferred embodiments of the present invention, and there is no any form of limitation to the present invention. Although the present invention has been disclosed as above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to equivalent embodiments with equivalent changes by using the technical content prompted above.
