[0026] Example
[0027] like Figure 1 As shown, the utility model proposes a power traction device for automobile chassis collision test, including a tractor 1 and a traction track 2. The tractor 1 is provided with two groups of rectangular holes, and a group of limiting columns 102 are movably penetrated in the rectangular holes. The two limiting columns 102 are fixedly connected with a lifting block 101, and one end of the two limiting columns 102 is connected with a friction block 103 for braking. The lifting block 101 can change the height of the friction block 103 by raising and lowering. The lifting block 101 is fixedly connected with a connecting plate 104, and the connecting plate 104 is fixedly connected with a storage plate 105 for adjusting the downward pressure of the friction block 103. By placing counterweights of different weights on the storage plate 105, the downward pressure of the friction block 103 can be changed, thereby changing the braking effect of the friction block.
[0028] like Figure 1 and Figure 2 As shown, a group of steel plates 201 are fixedly connected to the traction track 2, and the steel plates 201 are in contact with the friction blocks 103. Friction is generated by the contact between the steel plates 201 and the friction blocks 103, thereby forming a braking force for braking the tractor 1. A sensor 202 is fixedly installed on the traction track 2. The sensor 202 can be composed of a heating light and is used to trigger the sensor.
[0029] like Figure 1 and Figure 2 As shown, a group of slide rails 203 are provided on the traction track 2 , and a guide rail 204 is provided on the traction track 2 . Both the slide rails 203 and the guide rails 204 are used to limit the moving direction of the tractor 1 .
[0030] like Figure 1 and Figure 3 As shown, the storage plate 105 fits into a groove provided on the tractor 1, an arc-shaped slope is provided in the middle of the lifting block 101, the lifting block 101 contacts an extrusion block 106, and an arc-shaped slope is provided on the extrusion block 106. An electric cylinder 107 is fixedly connected to the extrusion block 106, and the model of the electric cylinder is the MTL series electric cylinder of Maitz. The electric cylinder 107 is fixedly installed on the tractor 1, and a controller 108 is fixedly installed on the tractor 1. The controller 108 is electrically connected to the electric cylinder 107, and the control line of the electric cylinder 107 is connected to the corresponding output port of the controller 108 for receiving instructions from the controller 108 to realize motion control, thereby driving the extrusion block 106 to move forward and backward, thereby achieving the purpose of lifting the lifting block 101 and separating from the lifting block 101.
[0031] like Figure 5As shown, two sets of pulleys 109 are fixedly installed on the tractor 1, and the pulleys 109 are used to drive the tractor 1 to move. Multiple pulleys 109 are fitted in the slide rail 203. A set of connecting columns 110 are fixedly connected to the tractor 1, and the two connecting columns 110 are fitted in the guide rail 204. The tractor 1 is located at a horizontal position of the friction block 103 and is equipped with an infrared sensor 111. The model of the infrared sensor 111 is Panasonic's AMN series infrared sensor. The infrared sensor 111 is electrically connected to the controller 108, and the output signal line of the infrared sensor 111 is connected to the input port of the controller 108. The model of the controller 108 is Siemens' S7-1200 series controller, which is used to transmit the detected signal.
[0032] like Figure 1 and Figure 4 As shown, a traction motor 3 is installed at one end of the traction track 2, and a traction steel cable 4 is rotatably connected to the traction motor 3. One end of the traction steel cable 4 is connected to the lifting block 101. The traction motor 3 and the traction steel cable 4 are used to pull the tractor 1 and the test vehicle to move.
[0033] In this embodiment, the vehicle to be tested is moved in front of the tractor 1, and then the tractor 1 is attached to the test vehicle. The traction motor 3 is then started to tighten the traction cable 4, thereby pulling the connecting column 110, thereby driving the tractor 1 and the test vehicle to move. When the tractor 1 moves above the sensing object 202, the infrared sensor 111 senses the sensing object 202, thereby sending an electrical signal to the controller 108. The controller 108 sends an instruction to the electric cylinder 107, thereby driving the electric cylinder 107 to retract quickly, thereby causing the squeezing block 106 to separate from the lifting block 101. Under the action of gravity, the limiting column 102, the friction block 103, the connecting plate 104 and the storage plate 105 are driven to descend, thereby generating friction between the friction block 103 and the steel plate 201, thereby forming a braking force for braking the tractor 1. Subsequently, a counterweight block can be installed on the storage plate 105 according to the braking effect to adjust the braking effect of the tractor.
[0034] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
