[0049] In the following description, in order to clearly demonstrate the structure and working mode of the utility model, many directional words will be used for description, but the words "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as restrictive terms.

[0050] The utility model relates to a linear impact system, which includes a track 6, a cover plate 7, a tractor 5, a traction rope 4, a driver, a mobile trolley 1, a guide base 2 and an impactor 3, wherein the track 6 extends along a first direction and one end is close to a sample to be tested. The tractor 5 is movably connected to the track. The traction rope 4 is annular and connected to the tractor 5 and the driver, and the driver can drive the traction rope 4 to rotate and then drive the tractor 5 to move along the track. The mobile trolley 1 is arranged on the track and located in front of the tractor 5, and the tractor 5 can push the mobile trolley 1 to move along the track. The guide base 2 is connected to the top surface of the mobile trolley 1 and is provided with a guide rail 21 extending along the first direction. The impactor 3 is located on the top surface of the guide base 2 and is movably connected to the guide rail 21 of the guide base 2, and is used to impact the test piece. When the tractor 5 pushes the mobile trolley 1 to move to the impact area, the tractor 5 releases the traction rope 4 and stops moving, the mobile trolley 1 is quickly stopped, and the impactor 3 moves forward along the guide rail 21 due to inertia to impact the sample to be tested.

[0051] The cover plate 7 is arranged at the impacted area, and is used to detachably cover the pit, and the pit is located below the impacted area, and is used to install a camera, so as to conveniently observe the shape of the sample to be tested when it is impacted from below.

[0052] The track 6 includes a first section 61 and a second section 62 along the first direction, the first section 61 extends along the first direction and is fixedly connected to the ground, the first section 61 has a first end and a second end along the first direction, and the first end is arranged opposite to the cover plate 7. One end of the second section 62 abuts against the first end of the first section 61, and the other end extends along the first direction, the second section 62 is detachably connected to the cover plate 7, and the second section 62 is located in the impacted area and is detachably connected to the cover plate 7.

[0053] The linear impact system also includes a linear impact device 100 and a damping device 300. The linear impact device 100 also includes: an impact head 200 arranged at the front end of the mobile trolley 1. The damping device 300 is arranged at the front end of the track and is used to lock the mobile trolley 1. The damping device 300 has a cavity for inserting the impact head 200. The driver is connected to the traction rope 4 and is used to drive the traction rope to move. Specifically, the driver is a driving motor, a turntable is connected to the driving motor, the traction rope 4 is wound on the turntable, the traction rope 4 is arranged in a closed loop along the track, the driving motor drives the turntable to rotate, and the rotation of the turntable drives the traction rope 4 to move, so that the driving motor drives the traction rope 4 to run in a closed loop along the track. The traction vehicle 5 clamps one side of the traction rope 4 forming a closed loop, and the traction rope 4 drives the traction vehicle 5 to move toward the direction of the sample to be tested. The traction vehicle 5 is gradually accelerated by the traction rope 4 while moving on the track, and can be accelerated to the speed required by the test. The mobile trolley 1 is placed on the track and is located in front of the tractor 5. When the tractor 5 moves, it pushes the mobile trolley 1 to move in the direction of the sample to be tested, thereby providing speed to the mobile trolley 1, so that the mobile trolley 1 accelerates to the speed required by the test. After the mobile trolley 1 reaches the acceleration, the tractor 5 releases the traction rope 4, and the tractor 5 continues to push the mobile trolley 1 along the track in the direction of the sample to be tested. The mobile trolley 1 continues to move forward until the impact head 200 is inserted into the cavity of the damping device 300, and the mobile trolley 1 stops moving. At this time, the impactor 3 moves along the guide rail 21 toward the sample to be tested due to inertia and impacts the sample to be tested.

[0054] In the existing linear impact test, the motor is directly connected to the transmitter in the short-range track, and the transmitter is pushed to push the mobile trolley 1 to drive the impactor 3 to impact the sample to be tested. In this structure, the speed of the mobile trolley 1 and the impactor 3 is relatively low, generally 8km / s, which cannot meet the actual impact requirements. If the existing device needs to reach the speed required by the test, it is necessary to increase the motor power, which will cause great costs and difficulties in actual implementation. However, this embodiment uses a driving motor to drive the traction rope 4. After the traction rope 4 pulls the traction vehicle 5, the traction vehicle 5 can move along the track to reach a sufficiently fast speed, and also pushes the mobile trolley 1 to the speed required by the test, which can meet the impact energy of 2.5t / 120km / h. After the mobile trolley 1 moves at high speed, it brakes and slows down. Relying on the inertia impactor 3 can slide freely, and the impactor 3 impacts the sample to be tested. By configuring the traction rope 4 and the traction vehicle 5, the ability of the linear impact device 100 is improved, which can meet the high quality and high speed requirements of the impactor 3. In addition, the structure of this embodiment is simple, easy to operate, and highly safe. In addition, compared with the tens of millions of purchase costs of existing equipment, this device reduces the test cost and is extremely convenient for the popularization of the test equipment.

[0055] In addition, the track in the utility model is generally 100-200 meters long, and the flatness and horizontality of the track are very high, generally requiring the error within ±2mm every 2m and the error within ±10mm every 5m. When performing a collision test, when the mobile trolley 1 hits the sample under test in the impact area, the front end of the mobile trolley 1 will rise or the rear end of the mobile trolley 1 will rise due to factors such as the height deviation of its center of mass and the stability of the damping device 300. After falling or stopping suddenly, the mobile trolley 1 will impact the second section 62 of the track twice, which may cause the second section 62 of the track to deform and be damaged. The damage and deformation of the second section 62 of the track will affect the traction accuracy of the tractor 5, thereby affecting the entire collision test.

[0056] The utility model sets the track into a first section 61 and a second section 62. The first section 61 adopts a layered casting method to fix the rail of the first section 61. The second section 62 is set to be detachable. After a preset period or a preset number of collision tests, or when it is found through inspection that the second section 62 no longer meets the test requirements, the second section 62 and the cover plate 7 can be removed, the second section 62 can be removed from the cover plate 7, and the second section 62 can be replaced, thereby ensuring that the entire track meets the test requirements, greatly saving maintenance costs and repair time.

[0057] The cover plate 7 includes a first plate 74 and a second plate 75, both of which extend along a first direction and are arranged relatively spaced apart along a second direction, wherein the second direction is perpendicular to the first direction. In addition, the first plate 74 and the second plate 75 are respectively formed by a top cover 72 and a bottom bracket 71, wherein the bottom bracket 71 is detachably connected to the pit, and the top cover 72 covers the top surface of the bottom bracket 71.

[0058] The second section 62 is formed by two L-shaped angle steels 621 disposed opposite to each other, and the two L-shaped angle steels 621 are detachably connected to the first plate 74 and the second plate 75 respectively.

[0059] Optionally, the first plate 74 and the second plate 75 are provided with L-shaped grooves 73 on the inner sides opposite to each other. The L-shaped grooves 73 are formed by the top cover 72 and the bottom bracket 71. It can be regarded as the top cover 72 protruding from the groove formed by the bottom bracket 71. The L-shaped grooves 73 extend along the first direction. The two L-shaped angle steels 621 are respectively located in the two L-shaped grooves 73 and are connected to the inner walls of the two L-shaped grooves 73 by bolts. The tops of the two L-shaped angle steels extend beyond the outer sides of the L-shaped grooves 73.

[0060] In other embodiments, the L-shaped angle steel 621 may also be connected to the opposite side of the first plate 74 and the second plate 75 by bolts.

[0061] Furthermore, if Figure 1 As shown, a baffle 11 for the tractor 5 to hit is provided on the side of the mobile trolley 1 facing away from the sample to be tested.

[0062] In addition, the baffle 11 is an elastic member, and the traction rope 4 is a steel wire rope. The baffle 11 is an elastic member, and after the traction vehicle 5 releases the traction rope 4, the impact of the traction vehicle 5 on the mobile trolley 1 is reduced, thereby ensuring the accuracy of the test.

[0063] Furthermore, this example relates to a tractor 5, such as Figure 3 As shown, the tractor 5 comprises: a vehicle body 51 and a clamping member arranged on the vehicle body 51. The clamping member is used to clamp or release the traction rope 4.

[0064] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, Figure 4 and Figure 5The guide wheel is not shown in the figure, and the clamping member includes: a driving handle 521, a first clamping plate 522 and a second clamping plate 523. The driving handle 521 includes: a handle body 5211 rotatably connected to the vehicle body 51, and an elliptical cam 5212 eccentrically connected to the handle body 5211 and driven to rotate by the handle body 5211. The first clamping plate 522 is fixed to the vehicle body 51, and the second clamping plate 523 is arranged opposite to the first clamping plate 522 along a direction perpendicular to the movement direction of the vehicle body 51, and the second clamping plate 523 is movably connected to the vehicle body 51, and the second clamping plate 523 and the first clamping plate 522 are matched to form a movable clamp that can clamp or release the traction rope 4. The second clamping plate 523 is used to be pushed by the elliptical cam 5212 to move toward the first clamping plate 522, and to clamp the traction rope 4 in cooperation with the first clamping plate 522. When the elliptical cam 5212 is in the clamping position, the protruding portion of the elliptical cam 5212 pushes the second clamping plate 523, so that the second clamping plate 523 and the first clamping accessory clamp the traction rope 4, and the second clamping plate 523 is clamped and positioned between the first clamping plate 522 and the elliptical cam 5212. When the elliptical cam 5212 is in the loosening position, the protruding portion of the elliptical cam 5212 rotates away from the second clamping plate 523, and the second clamping plate 523 can move away from the first clamping plate 522, and the second clamping plate 523 and the first clamping plate 522 loosen the traction rope 4. The plane of the elliptical cam 5212 pushes the second clamping plate 523 so that the second clamping plate 523 and the first clamping plate 522 clamp the traction rope 4, and the elliptical cam 5212 is rotated so that the long arc surface portion faces the second clamping plate 523, and at this time, the elliptical cam 5212 is away from the second clamping plate 523, and the second clamping plate 523 and the first clamping plate 522 are loosened. Through the cooperation of the first clamping plate, the second clamping plate and the driving handle, the elliptical cam can be rotated through the handle body, so that the first clamping plate and the second clamping plate can cooperate to clamp the traction rope. The handle body extends outside the vehicle body. When the tractor moves, the driving block on the moving path collides with the handle body, so that the handle body drives the elliptical cam to rotate, so that the first clamping plate and the second clamping plate release the traction rope. Through a simple structure, the tractor can meet the need to clamp the traction rope and be driven by the traction rope to move during use, and during the movement process, the handle body can be driven by external components without the need for operator operation, so that the first clamping plate and the second clamping plate release the traction rope.

[0065] In addition, if Figure 4 , Figure 5 and Figure 6 As shown, the first clamping plate 522 has a first clamping surface 5221 facing the second clamping plate 523, and the second clamping plate 523 has a second clamping surface 5231 facing the first clamping plate 522. The first clamping surface 5221 and the second clamping surface 5231 are at least partially toothed surfaces that match each other, so that the clamping surface and the second clamping surface 5231 have multiple arc surface areas that can clamp the traction rope 4.

[0066] In addition, if Figure 3 , Figure 4 and Figure 5 As shown, the tractor 5 further includes: a pair of mounting plates 53 spaced apart from each other along the moving direction of the vehicle body 51, and the second clamping plate 523 is slidably connected to the pair of mounting plates 53. The mounting plates 53 are provided with a slide groove 531 that moves in a direction perpendicular to the moving direction of the vehicle body 51, and the second clamping plate 523 at least partially extends out and is inserted into the slide groove 531, so that when the protruding portion of the elliptical cam 5212 rotates away from the second clamping plate 523, the second clamping plate 523 can slide away from the first clamping plate 522 along the slide groove 531.

[0067] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the second clamping plate 523 includes: a mounting plate 5232 at least partially inserted into the slide groove 531, and a second clamping plate body 5233 fixedly connected to the mounting plate 5232. The second clamping plate body 5233 cooperates with the first clamping plate 522 to clamp the traction rope 4.

[0068] Furthermore, if Figure 3 , Figure 4 and Figure 5 As shown, the second clamping plate body 5233 has a first toothed surface on one side facing the first clamping plate 522, and the second clamping plate body 5233 has a second toothed surface on one side facing the first clamping plate 522. When the elliptical cam 5212 is in the clamping position, the first toothed surface and the second toothed surface are at least partially separated to form a toothed space for clamping the traction rope 4, so as to better clamp the traction rope 4.

[0069] In addition, if Figure 3 , Figure 4 and Figure 5 As shown, the side of the mounting slide plate 5232 facing the first clamping plate 522 has a third toothed surface 5230 , and when the elliptical cam 5212 is located in the clamping position, the first toothed surface and the third toothed surface 5230 are meshed and abutted.

[0070] Further, as shown in Figure Figure 3 , Figure 4 and Figure 5 As shown, when the elliptical cam 5212 is in the clamping position, the handle body 5211 extends outside the vehicle body 51. A driving block is provided on the track, and the driving block is used to push the handle body 5211 to rotate. The rotation of the handle body 5211 drives the elliptical cam 5212 to rotate, so that the elliptical cam 5212 is in the loosening position. When the tractor 5 moves along the track to the driving block, since the handle body 5211 is outside the vehicle body 51, the driving block collides with the handle body 5211 on the moving tractor 5, so that the handle body 5211 rotates, drives the elliptical cam 5212 to rotate, and the elliptical cam 5212 no longer pushes the second clamping plate 523, and the second clamping plate 523 and the first clamping plate 522 release the traction rope 4.

[0071] Furthermore, if Figure 3 , Figure 4 and Figure 5 As shown, the elliptical cam 5212 and the handle body 5211 are respectively located on both sides of the vehicle body 51 .

The guide base 2 has a pair of limit stops 34 arranged at both ends of the guide rail 21, and the moving slider 31 is slidably located between the pair of limit stops 34, so that the impactor 3 will not be separated from the guide rail 21. The impact body 33 is used to move outside the extension direction of the guide rail 21 under inertia.

[0074] The damping device 300 further includes an energy absorbing tube, which is connected to the back plate, is located outside the installation space, and extends toward the side where the opening of the installation space is located. The energy absorbing tube is used to collapse toward the back plate. Both sides of the installation space width direction have energy absorbing tubes. The impact force of the test impact energy on the impact head 200 and the damping device 300 is shared, thereby protecting the impact head 200 and the damping device 300.

[0075] The linear impact device 100 includes: an impact head 200 arranged at the front end of the mobile trolley 1. A damping device 300 is arranged at the front end of the track for locking the mobile trolley 1. The damping device 300 has a cavity for inserting the impact head 200.
