By using different types and numbers of engines, the trolley can slide at different speeds to complete tests for different test equipment and different speed requirements; finally, a deceleration braking system can be used to safely decelerate the moving trolley to a stop.

[0003] Since the running speed of the trolley in the slide rail test is relatively high, there are relatively high requirements for the deceleration braking system.

[0040] In view of the technical problems existing in the prior art, an embodiment of the present invention provides a braking system for a slide rail test, as Figures 1-8As shown in the figure, the braking system includes two parallel slide rails 10 and a sliding carriage 20 arranged on the two slide rails 10; in a specific embodiment, the slide rails 10 are flexible slide rails. The braking system further includes a deceleration assembly 30, and the deceleration assembly 30 includes a first collar 31 sleeved on the slide rail 10 and a deceleration parachute 33 connected to the first collar 31 through a parachute cord 32, and the first collar 31 forms a closed loop. Here, the first collar 31 and the deceleration parachute 33 are both arranged on the two slide rails 10; in a specific embodiment, the deceleration assembly 30 further includes a fixing bracket 34 arranged on one side of the slide rail 10 for fixing the deceleration parachute 33, and the fixing bracket 34 is fixed to the ground. Specifically, the deceleration parachute 33 is fixed to the fixing bracket 34 through a hanging parachute line 35. The deceleration assembly 30 is configured such that when the sliding carriage 20 impacts the first collar 31 and drives the first collar 31 to move along the extending direction of the slide rail 10, the deceleration parachute 33 unfolds to slow down the moving speed of the sliding carriage 20. In a specific embodiment, the moving direction of the sliding carriage 20 is as Figure 1 , 2 shown by the arrow pointing in the direction. The sliding carriage 20 moves forward along this direction. When the sliding carriage 20 touches the first collar 31 and drives the first collar 31 to continue moving forward, the first collar 31 pulls the parachute cord 32 forward, the parachute cord 32 pulls the deceleration parachute 33, the deceleration parachute 33 breaks the hanging parachute line 35, and then drives the deceleration parachute 33 to unfold and break away from the fixing bracket 34. The unfolded deceleration parachute generates a certain aerodynamic resistance, and the sliding carriage 20 is decelerated gradually due to the resistance. Here, the method of breaking the hanging parachute line 35 to make the deceleration parachute 33 break away from the fixing bracket 34 enables the deceleration parachute 33 not to be damaged when breaking away from the fixing bracket 34, and it can also be reused.

[0041] In a specific embodiment, as Figures 1-8 shown, the braking system includes deceleration assemblies 30 symmetrically arranged on the two slide rails 10 respectively, that is, it includes two first collars 31 and two deceleration parachutes 33 sleeved on the slide rail 10. The symmetrically arranged deceleration assemblies 30 are a group, and a group includes two deceleration assemblies 30; when the sliding carriage 20 moves, the front end of the sliding carriage 20 will simultaneously impact the two first collars 31 and drive the two first collars 31 to move forward, thereby enabling the two deceleration parachutes 33 to unfold simultaneously, generating symmetric aerodynamic resistance to gradually decelerate the sliding carriage 20. The braking system in this embodiment is provided with two symmetric deceleration assemblies 30, which can effectively prevent the sliding carriage from shaking the track due to the aerodynamic resistance of the unilateral deceleration parachute and affecting the test.

[0042] The braking system provided in the embodiment of the present invention can effectively achieve the safe deceleration and stop of the high-speed moving pulley by setting a deceleration component, avoid the pulley colliding with the slide rail terminal facilities, causing the pulley parts to fly off the slide rail and cause damage to personnel and buildings, ensure the safety of the pulley and on-board equipment, meet the working needs of the slide rail test, and provide a safe deceleration and braking method for the slide rail test.

[0043] In a specific embodiment, the pulley 20 includes: two sliding shoes 23 respectively located on the two slide rails 10; a pulley body 22 connected and fixed to the two sliding shoes 23; and a protrusion 21 for cooperating with the first ring 31 is provided at one end of the sliding shoe 23 close to the deceleration assembly 30. Before the pulley 20 moves to the deceleration assembly 30, the protrusion 21 will be sleeved in the first ring 31, thereby driving the first ring 31 to move forward, so that the deceleration parachute 32 is deployed and separated from the fixing frame 34; this can prevent the pulley 20 from moving too fast and easily breaking or wearing off the first ring 31.

[0044] like Figure 4 As shown, the slide shoe 23 includes: two first connecting members 231 sleeved on the slide rail 10 and connected and fixed to the two ends of the side of the pulley body 22; an anti-wear pipe 232 sleeved on the slide rail 10 and connected and fixed to the two first connecting members 231; the two first connecting members 231 and the anti-wear pipe 232 are connected to form a whole. This design ensures that when the first ring 31 or the parachute rope 32 moves along the extension direction of the slide rail 10, the first ring 31 and / or the parachute rope 32 will not rub against the slide rail 10, that is, the friction will not occur. Figure 9 The portion A shown in the figure contacts the slide rail 10 to generate friction, thereby protecting the first ring 31 and the parachute rope 32 from damage; in practical applications, this embodiment enhances the strength of the pulley and is suitable for tests that require high pulley strength.

[0045] In a specific embodiment, Figure 5 As shown, the slide shoe 23 includes: two second connecting members 233 which are sleeved on the slide rail 10 and connected and fixed to the two ends of the side of the pulley body 22; and a wear plate 234 for connecting the two second connecting members 233, wherein the wear plate 234 is located on the side of the slide shoe away from the pulley body 22. Specifically, there are two wear plates 234 which are arranged opposite to each other and are respectively located on the upper side and the lower side of the slide rail 10; when the first ring 31 or the parachute rope 32 moves along the extension direction of the slide rail 10, the wear plate 234 can also prevent the first ring 31 and / or the parachute rope 32 from contacting with the slide rail 10 and generating friction, thereby protecting the first ring 31 and the parachute rope 32 from being damaged, and also preventing the occurrence of the following problems: Figure 9The situation where the shown part A contacts the slide rail 10 to generate friction; there is a gap between the inner plate surface of the wear-resistant plate 234 and the slide rail 10 to prevent the wear-resistant plate 234 from generating friction with the slide rail 10, thereby protecting the slide rail 10 from damage. Further, both ends of the sliding shoe 23 are respectively provided with a fixing block 235, and the wear-resistant plate 234 can be fixedly connected to the sliding shoe 23 through the two fixing blocks 235. This embodiment reduces the mass of the sliding carriage 20, thereby increasing the speed of the sliding carriage 20.

[0046] In a specific embodiment, the braking system includes a plurality of sets of deceleration components 30 arranged along the extending direction of the slide rail 10, and a plurality of deceleration components 30 are arranged on each slide rail 10. There is a certain interval distance between adjacent deceleration components 30, and this interval distance can be designed according to different operation requirements, different sliding carriage speeds and different test requirements. Thus, after the sliding carriage 20 passes through the first set of first loops 31, the first set of deceleration parachutes 33 is deployed to decelerate the sliding carriage 20. When the sliding carriage 20 decelerates to a certain extent and then passes through the second set of first loops 31, the second set of deceleration parachutes 33 is deployed to further decelerate the sliding carriage 20. In this embodiment, a plurality of sets of deceleration components 30 are arranged along the extending direction of the slide rail, mainly considering that the larger the area of the deceleration parachute 32, the greater the aerodynamic resistance generated, and the greater the resulting overload. And generating too large an overload at one time is likely to damage the devices carried on the vehicle. This embodiment gradually decelerates the sliding carriage 20 moving at high speed by setting a plurality of sets of deceleration components 30. While achieving a better deceleration effect on the sliding carriage 20, it prevents generating too large an overload on the sliding carriage 20 at one time, and avoids damage to the sliding carriage 20 and the vehicle-mounted equipment caused by excessive overload. For the slide rail test with a relatively fast speed of the sliding carriage 20, deceleration components 30 can be added at an appropriate distance; for the slide rail test with a relatively slow speed of the sliding carriage 20, the use of deceleration components 30 can be appropriately reduced to reduce the workload and improve work efficiency.

[0047] In one embodiment, the braking system further includes a buffer component 40 located on the side of the deceleration component 30 away from the sliding carriage 20; the buffer component 40 includes an elastic member 41, a second loop 42 sleeved on the slide rail 10, and a connecting band 43 with two ends respectively connected to the elastic member 41 and the second loop 42, and the second loop 42 forms a closed loop. In a specific embodiment, one end of the connecting band 43 away from the second loop 42 is sleeved on the elastic member 41. As Figure 1 、 2As shown, the connecting belt 43 includes an elastic first body 431 and an inelastic second body 432; one end of the elastic first body 431 is sleeved on the elastic member 41, the other end of the first body 431 is connected to one end of the inelastic second body 432, and the other end of the inelastic second body 432 is fixedly connected to the second collar 42. The buffer assembly 40 also has two symmetrically arranged groups, which can also effectively prevent the trolley 20 from shaking the track due to the resistance of the unilateral buffer assembly 40, affecting the test.

[0048] When the trolley 20 hits the first collar 31 during movement, driving the first collar 31 to move forward, so that the deceleration parachute 33 unfolds to generate aerodynamic resistance to decelerate the trolley 20, the decelerated trolley 20 continues to slide forward, hits the second collar 42, and drives the second collar 42 to move forward. The second collar 42 pulls the inelastic second body 432, and the second body 432 drives the elastic first body 431. The first body 431 is stretched to generate a pulling force to further decelerate the trolley 20. When the pulling force generated by the first body 431 reaches a certain level, the end of the first body 431 sleeved on the elastic member 41 disengages from the elastic member 41, so as to prevent the first body 431 from being overstretched and causing damage or fracture of the first body 431, and improve the service life of the buffer assembly 40.

[0049] In this embodiment, the buffer assembly is further provided to decelerate the trolley 20, shorten the sliding distance of the trolley 20, and prevent the trolley 20 from sliding too long and hitting the end setting of the slide rail, ensuring the safety of the trolley 20 and the on-vehicle equipment. In a specific embodiment, the elastic first body 431 is a rubber cord. In the embodiment where the second collars 42 are symmetrically arranged on the two slide rails 10 respectively, the elastic first bodies 431 are respectively fixedly connected to the two second collars 42 through two inelastic second bodies 432.

[0050] In one embodiment, the first collar 31 and / or the second collar 42 are fixed to the slide rail 10 by a plurality of support lines 50. In a specific embodiment, as Figure 3 shown, a plurality of support lines 50 are arranged along the circumferential direction of the slide rail 10. In one embodiment, the support line 50 is a thin cord or tape or other soft linear objects well-known in the art that are easily broken when the trolley passes through. In this embodiment, the first collar 31 and / or the second collar 42 are fixed to the slide rail by a plurality of support lines, so as to ensure that when the trolley 20 passes through the first collar 31 and / or the second collar 42, the trolley 20 can smoothly break the support line 50, drive the first collar 31 and / or the second collar 42, thereby decelerating the trolley 20, and ensuring that there is no friction between the first collar 31 and / or the second collar 42 and the slide rail 10.

[0051] In one embodiment, the braking system further includes a damping assembly 60 configured to generate a damping force on the movement of the sliding carriage 20; as Figure 1 、 2 shown, the damping assembly 60 includes a damping wheel 61 and a lacing 62 wound around the damping wheel 61; the free end of the lacing 62 is fixedly connected to the connecting belt 43. In one embodiment, the free end of the lacing 62 is connected to one end of the first section 431 sleeved on the elastic member 41, the lacing 62 is wound around the winch of the damping wheel 61, and a damper is installed on the damping wheel 61, and the damper can hinder the rotation of the winch. Specifically, the damper is a friction member installed on the damping wheel 61. When the winch rotates, the friction member can generate friction with the winch, thereby generating a damping force. After the first section 431 of the sliding carriage 20 drives the second collar 42 to move forward and the end of the first section 431 sleeved on the elastic member 41 disengages from the elastic member 41, when the first section 431 pulls the lacing 62, the lacing 62 drives the winch on the damping wheel 61, the winch starts to rotate, the damper provides a certain damping force, and then provides a damping force to the movement of the sliding carriage, further decelerating the sliding carriage to a stop. In another specific embodiment, the lacing 62 is a winch belt or a connecting rope.

[0052] In this embodiment, since the free end of the lacing 62 is fixedly connected to the connecting belt 43, that is, connected to the end of the first section 431 sleeved on the elastic member 41, for the slide rail test with a relatively slow trolley speed, that is, in the case where the trolley generates a relatively small inertial force, the connecting belt 43 between the elastic member 41 and the second collar 42 further decelerates the trolley on the slide rail until it stops sliding. In a specific example, the elastic member 41 is a constant force decoupling hook. For the slide rail test with a relatively fast trolley speed, the trolley generates a relatively large inertial force, and the first section 431 will be stretched to a large extent. When the first section 431 is stretched to a certain extent, the end of the first section 431 sleeved on the elastic member 41 disengages from the elastic member 41. Since the free end of the lacing 62 is fixedly connected to the end of the first section 431 sleeved on the elastic member 41, the disengaged first section 431 pulls the lacing 62, and the lacing 62 drives the winch on the damping wheel 61, and the winch starts to rotate. The damper on the damping wheel 61 provides a certain damping force, thereby providing a damping force to the movement of the trolley and further decelerating the trolley, so as to achieve gradual deceleration of the trolley on the slide rail until it stops sliding. In another specific example, for the slide rail test with a relatively slow or fast trolley speed, the elastic member is arranged such that when the first section 431 is stretched to a certain extent, the end of the first section 431 sleeved on the elastic member 41 will disengage from the elastic member 41, thereby providing a damping force through the damping assembly, providing a damping force to the movement of the trolley, and decelerating the trolley until it stops sliding. This example avoids excessive stretching of the first section 431, which may cause damage or breakage of the first section, and ensures the reliability of the buffer assembly 40. The above damping assembly 60 also has two symmetrically arranged groups, which can also effectively prevent the trolley from shaking the track due to the damping force of the unilateral damping assembly 60, affecting the test. In a specific embodiment, the above buffer assembly 40 also has a protective effect on the damping assembly 60; specifically, when the trolley 20 impacts the second collar 42, the second collar 42 pulls the connecting belt 43 in the buffer assembly 40 to run, and the connecting belt 43 pulls the damping assembly 60 and generates a pulling force on the damping assembly 60; since the first section 431 of the connecting belt 43 has elasticity, the connecting belt 43 will play a certain buffering role when pulling the damping assembly 60, and will not cause a sudden large pulling force on the damping assembly 60, thereby avoiding the situation where the damping assembly 60 is damaged. In a specific embodiment, the braking system may also only include a deceleration assembly 30 or / and a buffer assembly 40 or / and a damping assembly 60. Through the buffer assembly 40 and the damping assembly 60, the trolley can also be decelerated, shortening the sliding distance of the trolley, avoiding the trolley sliding too long and hitting the terminal setting of the slide rail, and ensuring the safety of the trolley and the on-vehicle equipment.

[0053] Those skilled in the art should understand that the above several implementation manners can also be freely combined. In a specific implementation manner, the braking system includes a deceleration component 30, a buffer component 40 located on the side of the deceleration component 30 away from the sliding carriage 20, and a damping component 60. By setting the above components, the sliding carriage is decelerated step by step in this embodiment, so as to safely decelerate the sliding carriage moving at high speed to a stop, avoid the sliding carriage hitting the terminal facilities of the slide rail 10, and prevent the parts of the sliding carriage from flying off the slide rail and causing damage to personnel and buildings, thus ensuring the safety of the sliding carriage and the on-vehicle equipment. The present invention makes no limitation thereto.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
