Description

Technical Field

[0001] This utility model relates to the field of collision testing of trackless manned vehicles in mines, and in particular to a collision testing device for trackless manned vehicles. Background Technology

[0002] In mining operations, trackless passenger vehicles serve as an important means of transportation, undertaking the crucial task of rapid and efficient transfer. Due to the complex underground environment of mines, there are many risk factors such as narrow tunnels, uneven road surfaces, and poor visibility, making vehicles prone to collision accidents during operation. Therefore, it is necessary to conduct collision tests on trackless passenger vehicles.

[0003] However, most existing crash test devices are designed and modified according to highway vehicle test standards, which makes it difficult to realistically simulate the complex road conditions and collision scenarios in mines. When trackless mining vehicles are running underground, collisions can easily occur in different scenarios such as vehicles hitting rock walls or fixed obstacles. Existing test devices can only perform single-form collision simulations, making it difficult to test different collision conditions and reducing the effectiveness of crash tests. To address this issue, we propose a trackless mining vehicle crash test device to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Unless otherwise specified, the methods used in the present utility model are conventional methods; unless otherwise specified, the raw materials and apparatus used are conventional commercially available products.

[0020] The test host, trackless manned test vehicle, and geared motor in this utility model are all common and known electrical devices in the prior art. This application will not elaborate on their models or internal structures.

[0021] Please see Figure 1-4In this utility model, a collision testing device for a trackless passenger vehicle includes a test base 2. A support base 3 is fixedly connected to one side of the test base 2. A transmission slide 7 is provided above the support base 3. A reduction motor 6 is fixedly installed on one side of the transmission slide 7. A transmission screw 8 is fixedly installed at the output end of the reduction motor 6. A threaded slider 9 is threadedly connected to the outer surface of the transmission screw 8. A connecting plate 10 is fixedly connected to the bottom surface of the threaded slider 9. A movable support plate 1 is fixedly connected to one side of the connecting plate 10. A deformable barrier plate 20 and a rigid obstacle avoidance plate 2 are respectively fixedly installed on one side of the movable support plate 1. The test base 2 has a raised barrier plate 22 and a trackless manned test vehicle 4 on its upper surface. The trackless manned test vehicle 4 is equipped with various types of sensors, including acceleration sensors, displacement sensors, force sensors and strain gauges. The acceleration sensors are used to measure the acceleration changes of the vehicle during the collision process, the displacement sensors monitor the deformation displacement of key parts of the vehicle, the force sensors measure the forces on each component during the collision, and the strain gauges are used to detect the strain of the vehicle structure. The sensor signals are transmitted to the data acquisition system in real time through a wireless transmission module to ensure the timeliness and accuracy of data acquisition.

[0022] In this embodiment: driven by the reduction motor 6 and driven by the threaded transmission of the transmission screw 8 and the threaded slider 9, the rotational motion of the motor can be converted into linear motion. The threaded slider 9 drives the movable support plate 1 to move through the connecting plate 10, thereby enabling the deformable barrier plate 20, rigid obstacle plate 21 and raised barrier plate 22 installed on the movable support plate 1 to flexibly adjust their positions. Different types of collision barriers are arranged on the driving path of the trackless manned test vehicle 4 to realize the simulation test of various collision conditions.

[0023] As a technical optimization of this utility model, a limiting hole 12 is provided on one side of the support base 3, and a limiting slide plate 13 is slidably connected to the inner wall of the limiting hole 12. One side of the limiting slide plate 13 is fixedly connected to one side of the movable support plate 1. Two limiting grooves 5 are provided on the upper surface of the test base 2. A guide ramp 19 is provided at one end of the test base 2. One end of each of the two limiting grooves 5 extends above the guide ramp 19. Two limiting baffles 18 are fixedly connected to the outer surface of the test base 2. The bottom end of the trackless manned test vehicle 4 extends into the interior of the limiting grooves 5.

[0024] In this embodiment: the sliding cooperation between the limiting hole 12 and the limiting slide plate 13 can provide guidance and limit for the movement of the movable support plate 1, ensuring that the barrier plate will not deviate during the movement, improving the accuracy of position adjustment. The limiting slide groove 5 constrains and guides the travel path of the trackless manned test vehicle 4. Combined with the guiding ramp 19, it assists the trackless manned test vehicle 4 to smoothly enter the test starting position. In addition, the limiting baffle 18 prevents the trackless manned test vehicle 4 from leaving the test path during the collision, ensuring the safety of the test process.

[0025] As a technical optimization of this utility model, the bottom surface of the transmission slide 7 is fixedly connected to two mounting plates 16, and the bottom surface of the two mounting plates 16 is provided with mounting holes 17. The inner wall of the transmission slide 7 is fixedly embedded with two bearings 11, and the inner rings of the two bearings 11 are fixedly connected to the outer surfaces of both ends of the transmission screw 8. A support plate 14 is fixedly connected to one side of the support base 3, and a test host 15 is fixedly installed on one side of the support plate 14. The test host 15 uses an industrial-grade computer as the core control unit and is equipped with dedicated control software. The control software has a user-friendly human-machine interface, and the tester can set test parameters, such as collision speed, through the control interface and monitor the operating status of the test device in real time.

[0026] In this embodiment: the mounting plate 16 and mounting hole 17 facilitate the stable installation of the transmission slide 7 on the support base 3, ensuring its installation stability. The bearing 11 and the transmission screw 8 cooperate to reduce the frictional resistance when the transmission screw 8 rotates. The support plate 14 provides an installation position for the test host 15. Using the test host 15, the collision force, acceleration, deformation and other data of the trackless manned test vehicle 4 can be collected in real time at close range and stably when a collision occurs, providing reliable data support for subsequent analysis of the performance of the trackless manned vehicle in mining under different collision conditions.

[0027] The working principle of this utility model is as follows: When in use, the guide ramp 19 and the limiting slide 5 can help the trackless manned test vehicle 4 enter the test starting position and place the trackless manned test vehicle 4 to be tested above the test base 2. When different collision conditions need to be simulated, the reduction motor 6 on one side of the transmission slide 7 is started to run. The output end of the reduction motor 6 drives the transmission screw 8 to rotate, which enables the threaded slider 9 to move along the transmission screw 8 under the threaded transmission. The threaded slider 9 drives the moving support plate 1 to move through the connecting plate 10. Then, the deformable barrier plate 20, rigid obstacle plate 21 and raised barrier plate 22 fixedly installed on one side of the moving support plate 1 move accordingly. Therefore, different types of barrier plates can be moved to the front of the trackless manned test vehicle 4 to simulate various collision scenarios such as vehicle and rock wall, vehicle and fixed obstacle.

[0028] After adjusting the position of the barrier, the trackless manned test vehicle 4 travels at the set speed and path and collides with the corresponding barrier. During the collision, the test host 15 collects various data in real time, such as the collision force, acceleration, and deformation of the trackless manned test vehicle 4, to provide a basis for subsequent analysis of the performance of the trackless manned vehicle in mining under different collision conditions.

[0029] However, the above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
