Description

Technical Field

[0001] The utility model belongs to the field of railway vehicle testing, and more specifically, relates to a static strength test loading device for an iron filings cleaning vehicle. Background Art

[0002] The iron filings cleaning vehicle is mainly used for cleaning the iron filings ground in the ballastless track inside and outside the tunnel, and can also take into account the dirt such as dust, solid debris, and small stones deposited on the surface of the ballastless track outside the tunnel, to avoid the dirt being rolled up by the high-speed running of the EMU and damaging the vehicle and line equipment, and to ensure the safe operation of the EMU. The whole vehicle suction system has sweeping and suction methods, magnetic suction methods, peeling methods, and flushing methods. The body of the iron filings cleaning vehicle adopts an integral load-bearing structure, which is mainly composed of a cab, a frame, a coupler buffer device, and a fender; the cab is mainly composed of driver's cabs at both ends, equipment rooms, fan rooms, and dirt rooms, and the position of the water tank adopts a truss structure; the frame, as the main load-bearing part of the under-hung components, is mainly composed of front and rear end traction beams, side beams, side bearing beams, cross beams, longitudinal beams, and various suspension hangers, etc., and the material is Q355B, so that the frame can have sufficient strength and stiffness. When the steel structure of the body of the iron filings cleaning vehicle is subjected to a static strength test, when simulating the vertical load force of the under-vehicle equipment on the body, a method of adding counterweights at the installation positions of the under-vehicle equipment is adopted. Due to the narrow space under the vehicle, it is inconvenient to operate during the static strength test. At the same time, due to the area limitation, auxiliary equipment such as cranes and forklifts cannot be used, resulting in low overall work efficiency and slow test progress. At the same time, due to the inconsistent installation methods of the magnetic suction device and the sweeping and suction device of the iron filings cleaning vehicle with those of other vehicles, there is no relevant loading scheme. To solve the problems of narrow space, inconvenient operation, low work efficiency, and no relevant loading scheme during the static strength test of the body of the grinding iron filings cleaning vehicle, a loading device that can match the static strength test of the iron filings cleaning vehicle is urgently needed to solve the existing problems. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide a static strength test loading device for an iron filings cleaning vehicle. The completed static strength test loading device can effectively simulate the under-hung components and apply a vertical load force to the vehicle body, so that the static strength test of the vehicle body can be successfully completed.

[0026] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] The present invention provides a static strength test loading device for an iron filings cleaning vehicle, including:

[0028] A mounting base, which is arranged on the vehicle frame;

[0029] A connecting mechanism, the upper end of which is connected to the mounting base, and the lower end of the connecting mechanism is connected to the simulated counterweight through a chain block or a hand winch.

[0030] Specifically, the loading device is to install the mounting base on the iron filings cleaning vehicle, then install the connecting mechanism on the mounting base, and finally hang the simulated counterweight on the connecting mechanism, so that the simulated counterweight can apply a vertically downward load force to the vehicle frame. In this way, when various tests of the iron filings cleaning vehicle are carried out, the actual operating conditions can be simulated.

[0031] Optionally, the mounting base is provided with mounting holes, and the mounting base and the connecting mechanism are connected by a pin shaft.

[0032] Optionally, the mounting base is welded to the vehicle frame.

[0033] Specifically, in order to ensure that the simulated counterweight can be stably connected to the vehicle frame, a mounting seat is welded on the vehicle frame, which can improve the connection strength. In addition, the mounting seat is connected to the connecting mechanism by means of pin hole fit, which makes the operation more convenient when applying static load.

[0034] Optionally, the connecting mechanism includes a scraper plate and a pull plate. The pull plate penetrates through the lower end of the scraper plate, and the pull plate is perpendicularly connected to the scraper plate. The upper end of the scraper plate is connected to the mounting seat.

[0035] Optionally, a first opening is provided on the scraper plate, and second openings are correspondingly provided in the areas on both sides of the pull plate where the pull plate is located. The second openings are connected to a chain block or a hand winch.

[0036] Specifically, the scraper plate and the pull plate are welded to form a connecting mechanism. The connecting mechanism is connected to the mounting hole of the mounting seat through the first opening at the upper end of the pull plate, and then connected to a chain block or a hand winch through two second openings on the scraper plate. In this way, it can be connected from one point of the mounting seat to the relatively large simulated counterweight and ensure the stability of the connection.

[0037] Optionally, the areas of the pull plate on both sides of the scraper plate are the same.

[0038] Optionally, the opening directions of the first opening and the second opening are perpendicular to each other.

[0039] Specifically, in order to ensure that after the simulated counterweight is installed, the iron filings cleaning vehicle is more evenly loaded with vertical loads, both the scraper plate and the mounting seat are arranged along the same axis. When it comes to the pull plate, the connection area is increased. The first opening and the second opening are symmetrically arranged with respect to the scraper plate, so that the simulated counterweight will not tilt after connection, and the state of the magnetic attraction device and the sweeping and suction device installed on the vehicle frame can be truly simulated.

[0040] Optionally, the weight of the simulated counterweight is 1.1 to 1.3 times the weight of the magnetic attraction device or the sweeping and suction device.

[0041] Specifically, when conducting the static strength test of the vehicle body steel structure, it is necessary to simulate and load the original weights of the magnetic attraction device and the sweeping and suction device. According to different working conditions, it is also necessary to load 1.1 times and 1.3 times the original weight of this component. In order to ensure the integrity of each device, the original components cannot be used for loading during the test, so corresponding simulated counterweights need to be manufactured to meet the requirements.

[0042] Optionally, the simulated counterweight is in the shape of a cuboid, and a plurality of lifting holes are respectively provided on the simulated counterweight along the length direction and the width direction.

[0043] Specifically, multiple lifting holes are provided on the simulated counterweight, which can meet the corresponding counterweight simulation under different weights and different working conditions. At the same time, a chain block / hand winch is used to lift the counterweight in different states. Meanwhile, when designing the structure, multiple lifting holes are also provided on the other two surfaces of the simulated counterweight, which can meet the use under another working condition and can also adjust the lifting position to meet different working conditions, with strong on-site practicability.
