[0036] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] An embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer, which can solve the problem of how to perform emergency parking and braking of a ship model test trailer during a high-speed running experiment in the related art.

[0038] See also Figures 1 to 4As shown, an embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer, comprising:

[0039] The trailer support 100 is located on the top of the steel rail 101 and is used to connect a ship model test trailer (not shown in the figure). The ship model test trailer moves on the steel rail 101 along the length direction of the steel rail 101.

[0040] The sliding mechanism 200 includes a bracket 210 fixed to the trailer support 100, and a connecting frame 220 is slidably connected to the bracket 210 and moves along the width direction of the rail 101. The connecting frame 220 is fixedly connected to a guide wheel group 230 located on both sides of the rail 101 and slidably connected to the rail 101.

[0041] The guide wheel group 230 is fixedly connected to the connecting frame 220. It is located on both sides of the rail 101 and is slidably connected to the rail 101 to adjust the left and right positions of the connecting frame 220 on the bracket 210 according to the bending direction of the rail 101, so that the brake mechanism 300 located on the connecting frame 220 and the rail 101 always maintain a set distance.

[0042] The brake mechanism 300 includes a housing 301 fixed to the connecting frame 220. The housing 301 is a rectangular structure with an open bottom and closed edges. Within the housing 301 are a brake assembly 310, a first drive mechanism 320 that drives the brake assembly 310 to clamp the rail 101, and a second drive mechanism 330 that drives the brake assembly 310 to disengage and clamp the rail 101.

[0043] When the ship model test trailer is running normally on the rail 101, the brake mechanism 300 does not participate in the braking action of the rail 101. The guide wheel group 230 of the sliding mechanism 200 is slidingly connected to both sides of the rail 101 to adjust the distance between the brake mechanism 300 and the rail 101 according to the bending direction of the rail 101 to prevent the brake mechanism 300 from rubbing against the rail 101.

[0044] When the ship model test trailer requires braking, the second drive mechanism 330 drives the brake assembly 310 to clamp the rail 101 to brake the ship model test trailer. If the ship model test trailer malfunctions, such as an unexpected power outage, the second drive mechanism 330 fails, and the first drive mechanism 320 urgently drives the brake assembly 310 to clamp the rail 101 to brake, thereby improving the safety performance of the ship model test trailer.

[0045] The adaptive box-type closed emergency brake of the present embodiment is provided with a sliding mechanism 200 on the trailer support 100. The sliding mechanism 200 is provided with a guide wheel assembly 230 that is slidably connected to the rail 101. The sliding mechanism 200 can change and adjust the distance between the brake mechanism 300 and the rail 101 along the direction of the rail 101. When the brake mechanism 300 is not required to brake, the brake mechanism 300 always maintains a set distance from the rail 101 to prevent it from rubbing against the rail 101.

[0046] The brake mechanism 300 comprises a housing 301 fixed to the connecting frame 220. Within the housing 301 are a brake assembly 310, a first drive mechanism 320 that drives the brake assembly 310 to clamp the rail 101, and a second drive mechanism 330 that drives the brake assembly 310 to disengage and clamp the rail 101. The first drive mechanism 320 can urgently drive the brake assembly 310 to clamp the rail 101 and achieve braking if the second drive mechanism 330 fails, thereby improving the safety of the ship model test trailer.

[0047] In some alternative embodiments: See Figures 2 to 4 As shown, an embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer, wherein the brake assembly 310 of the adaptive box-type closed emergency brake includes two brake clamps 311 located on both sides of the rail 101 and both rotatably connected to the box body 301, and a wedge block 316 is slidably connected between the two brake clamps 311.

[0048] The first drive mechanism 320 includes a spring seat 321 fixedly connected to the housing 301. The spring seat 321 is provided with an elastic member that pulls the wedge block 316 to enable the two brake calipers 311 to clamp the rail 101. The second drive mechanism 330 includes a telescopic mechanism 331 fixedly connected to the housing 301. The telescopic mechanism 331 is used to push and pull the wedge block 316 to enable the two brake calipers 311 to clamp and release the rail 101.

[0049] The brake assembly 310 of the embodiment of the present application is provided with two brake calipers 311 located on both sides of the rail 101 and both are rotatably connected to the box 301. The two brake calipers 311 rotate in the box 301 in directions of approaching and moving away from the rail 101 to achieve clamping and detachment from the rail 101.

[0050] A wedge block 316 is slidably connected between the two brake clamps 311. The wedge block 316 has an inverted triangle or inverted trapezoidal structure. The wedge block 316 can drive the two brake clamps 311 to clamp and disengage the rail 101 under the drive of the first drive mechanism 320 and the second drive mechanism 330, thereby realizing braking and releasing the brake.

[0051] The second driving mechanism 330 is provided with a telescopic mechanism 331 fixedly connected to the box body 301. The telescopic mechanism 331 pushes and pulls the wedge block 316 to clamp and detach the two brake clamps 311 from the rail 101, so that when the ship model test trailer is operating normally, the telescopic mechanism 331 is used to control the two brake clamps 311 to clamp and detach from the rail 101.

[0052] The first drive mechanism 320 is provided with a spring seat 321 fixed in the housing 301. The spring seat 321 is provided with an elastic member that pulls the wedge block 316 to clamp the two brake calipers 311 to the rail 101. When the second drive mechanism 330 fails, the elastic member of the first drive mechanism 320 pulls the wedge block 316 to clamp the two brake calipers 311 to the rail 101, achieving emergency braking.

[0053] In some alternative embodiments: See Figures 2 to 4 As shown, an embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer, one end of the brake caliper 311 of the adaptive box-type closed emergency brake extends out of the box body 301 and is provided with a brake pad 314 frictionally connected to the rail 101, and the end of the brake caliper 311 away from the brake pad 314 is rotatably connected to a roller 312 slidingly connected to a wedge block 316.

[0054] The brake caliper 311 is rotatably connected to a support shaft 313 fixedly connected to the box body 301. The support shaft 313 is located in the middle position of the brake caliper 311. The brake caliper 311 rotates around the support shaft 313 to approach and move away from the rail 101. A spring 315 is provided between the brake caliper 311 and the box body 301 to drive the brake caliper 311 to move in a direction away from the rail 101.

[0055] In this embodiment of the present application, a brake pad 314 is provided at one end of the brake caliper 311, which is frictionally connected to the rail 101. The brake pad 314 is fixedly connected to the brake caliper 311 via bolts, facilitating replacement and maintenance of the brake pad 314. A roller 312 on the brake caliper 311 is slidably connected to a wedge block 316 to reduce friction between the wedge block 316 and the brake caliper 311, thereby reducing the driving force of the first drive mechanism 320 and the second drive mechanism 330.

[0056] A support shaft 313 fixedly connected to the box body 301 is rotatably connected to the brake clamp 311. The support shaft 313 rotatably supports the brake clamp 311 so that the two symmetrically arranged brake clamps 311 can synchronously rotate in the direction of approaching and moving away from the rail 101 to achieve braking and braking cancellation.

[0057] As the wedge block 316 slides away from the brake pad 314, the clamping force between the two symmetrically arranged brake clamps 311 and the rail 101 gradually decreases until the brake pad 314 on the brake clamps 311 is released from the rail 101. To prevent the brake pad 314 from still contacting the rail 101 due to vibration or gravity, the spring 315 between the brake clamp 311 and the housing 301 drives the brake clamp 311 to rotate away from the rail 101, maintaining a set distance between the brake pad 314 and the rail 101.

[0058] In some alternative embodiments: See Figure 3 As shown, an embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer. The elastic member of the adaptive box-type closed emergency brake includes a pull rod 324 at one end that penetrates a spring seat 321 and is fixedly connected to a wedge block 316. A disc spring support cover 323 is fixedly provided at the other end of the pull rod 324. A plurality of disc springs 322 are provided between the disc spring support cover 323 and the spring seat 321 and are sleeved on the pull rod 324.

[0059] The elastic member of the embodiment of the present application is provided with a pull rod 324, one end of the pull rod 324 is inserted into the spring seat 321 and is fixedly connected to the wedge block 316, and the other end of the pull rod 324 is provided with a disc spring support cover 323. A plurality of stacked disc springs 322 are provided between the disc spring support cover 323 and the spring seat 321. The disc spring 322 can pull the wedge block 316 through the pull rod 324 to enable the two brake calipers 311 to clamp the rail 101, thereby achieving emergency braking.

[0060] In some alternative embodiments: See Figure 3 As shown, an embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer. The telescopic mechanism 331 of the adaptive box-type closed emergency brake is a cylinder fixed to the box body 301. The telescopic arm of the cylinder is fixedly connected to a connecting sleeve 332. A pull rod 324 fixedly connected to a wedge block 316 is threadedly connected to the connecting sleeve 332. The cylinder drives the wedge block 316 to reciprocate through telescopic motion, so that the wedge block 316 drives the two brake calipers 311 to clamp and release the rail 101.

[0061] A sliding sleeve 333 connected to the connecting sleeve 332 is fixedly mounted on the housing 301. The connecting sleeve 332 slides and retracts up and down within the sliding sleeve 333. An adjusting screw (not shown) is threadedly connected to the wedge block 316 and abuts against the spring seat 321. The adjusting screw is used to adjust the distance between the wedge block 316 and the spring seat 321.

[0062] The telescopic mechanism 331 of the present embodiment is a cylinder fixed to the housing 301. The telescopic arm of the cylinder is fixedly connected to a connecting sleeve 332. The connecting sleeve 332 has an internal thread. The top of the pull rod 324 has an external thread connected to the connecting sleeve 332. The telescopic arm of the cylinder has an external thread connected to the connecting sleeve 332, and a nut is provided on the telescopic arm of the cylinder to secure the telescopic arm to the connecting sleeve 332.

[0063] The cylinder uses its telescopic arm to move the wedge block 316 up and down, thereby enabling the two brake clamps 311 to clamp and release the rail 101. When the cylinder's telescopic arm drives the wedge block 316 upward, the two brake clamps 311 release the rail 101, releasing the brake. This simultaneously drives the pull rod 324 upward, compressing the butterfly spring 322 to store energy. When the cylinder's telescopic arm drives the wedge block 316 downward, the two brake clamps 311 clamp the rail 101, achieving braking.

[0064] In some alternative embodiments: See Figure 5 As shown, an embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer. The bracket 210 of the adaptive box-type closed emergency brake includes a mounting plate 211 fixedly connected to the trailer support 100, and two symmetrical and spaced outer ear plates 212 are fixedly provided on the mounting plate 211. The connecting frame 220 includes a fixing plate 221 fixedly connected to the box body 301, and two symmetrical and spaced inner ear plates 222 are provided on the fixing plate 221.

[0065] The two inner ear plates 222 are located between the two outer ear plates 212, with a gap between adjacent inner ear plates 222 and outer ear plates 212. Reinforcement plates are fixedly connected to the mounting plate 211 at each end of the outer ear plates 212. The two inner ear plates 222 are fixedly connected by a connecting plate 225. Two shafts 223 are provided between the two outer ear plates 212, slidably connecting the two inner ear plates 222. The axes of the shafts 223 are perpendicular to the axis of the rail 101.

[0066] The two inner ear plates 222 are provided with through holes for inserting the shaft rod 223, and a sliding sleeve (not shown in the figure) is fixed in the through hole and is slidably connected to the shaft rod 223. The two outer ear plates 212 are provided with an axis end baffle 224 on the side away from the inner ear plate 222 to fix the shaft rod 223 on the outer ear plate 212. The axis end baffle 224 is connected to the shaft rod 223 by screws to fix the shaft rod 223 on the outer ear plate 212.

[0067] The trailer support 100 includes a positioning frame 102 connected to a bracket 210. A guide post 103 is located within the positioning frame 102 and vertically slidably connected to the positioning frame 102. A top plate 104 is located on top of the guide post 103, which is fixedly connected to the ship model test trailer. The ship model test trailer is driven by the trailer support 100 to move the sliding mechanism 200 and the brake mechanism 300.

[0068] In the embodiment of the present application, two shafts 223 are provided between the two outer ear plates 212 to slidably connect the two inner ear plates 222. The two inner ear plates 222 are located between the two outer ear plates 212, and a gap is preset between adjacent inner ear plates 222 and outer ear plates 212. The two inner ear plates 222 move between the two outer ear plates 212 along the axis of the two shafts 223.

[0069] The guide wheel assembly 230 is fixed to the bottom of the two inner ear plates 222. The guide wheel assembly 230 is slidably connected to the two sides of the rail 101, thereby adjusting the left and right sliding of the two inner ear plates 222 on the shaft 223 according to the turning direction of the rail 101. The gap between the inner ear plates 222 and the outer ear plates 212 ensures that the inner ear plates 222 have sufficient space to move.

[0070] How it works

[0071] An embodiment of the present application provides an adaptive box-type closed emergency brake for a ship model test trailer. Since the adaptive box-type closed emergency brake of the present application is provided with a trailer support 100, the trailer support 100 is located on the top of the rail 101 and is used to connect the ship model test trailer; a sliding mechanism 200, the sliding mechanism 200 includes a bracket 210 fixed on the trailer support 100, and a connecting frame 220 that moves along the width direction of the rail 101 is slidably connected to the bracket 210, and a guide wheel group 230 is fixedly connected to the connecting frame 220 and is located on both sides of the rail 101 and is slidably connected to the rail 101; a brake mechanism 300, the brake mechanism 300 includes a box body 301 fixed on the connecting frame 220, and a brake assembly 310, a first drive mechanism 320 that drives the brake assembly 310 to clamp the rail 101, and a second drive mechanism 330 that drives the brake assembly 310 to disengage and clamp the rail 101.
