[0026] The beneficial effects of the present invention are:

[0027] First, the technical solution adopted by the present invention is that the first displacement component of the displacement device is connected to the main body of the brake belt guiding device.

By partially inserting the external teeth into the hollow cylinder of the first displacement component and meshing with the internal teeth of the first displacement component, when it is necessary to adjust the tension force of the brake belt, the second displacement component equipped with the horizontal belt guiding mechanism is pulled out from the internal teeth of the first displacement component, rotated by an appropriate angle, and then inserted into the first displacement component to mesh with it, so as to realize that the spatial position of the central axis of the vertical belt guiding wheel of the horizontal belt guiding mechanism and the horizontal belt guiding wheel of the vertical belt guiding mechanism can form a vertical angle or any angle, and further adjust the angle between the brake belt at the position of the horizontal belt guiding mechanism and the brake belt at the position of the vertical belt guiding mechanism to form a vertical angle or any angle, meeting the requirements of different occasions and working conditions, improving the tension force of the brake belt, and solving problems such as the brake belt jumping out of the groove during movement;

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0042] It should be noted that before the aircraft or high-speed heavy-duty moving parts need to be braked, the arresting net, arresting cable and other forms of arresters are placed in the running track of the aircraft or high-speed heavy-duty moving parts, or fixedly placed somewhere, and then started before they should be used.

[0043] When the aircraft or high-speed heavy-duty moving parts are engaged with the arresting net or arresting cable, a huge kinetic energy is transmitted to the arresting net or arresting cable. The arresting net or arresting cable forms a safety protection barrier for the aircraft or high-speed heavy-duty moving parts. The kinetic energy is then transmitted through the arresting net or arresting cable to the brake belt, and further through the brake belt to the brake belt recovery device. The brake belt recovery device consumes the huge kinetic energy of the aircraft or high-speed heavy-duty moving parts before they are stopped, so as to stop the aircraft or high-speed heavy-duty moving parts safely within a controllable acceleration range. During the stopping process, the brake belt is pulled out passively by the brake belt recovery device and the brake belt guiding device, etc., and moves along with the aircraft and high-speed heavy-duty moving parts in the direction of the arresting net or arresting cable.

[0044] As Figure 2 shown, the present invention provides a brake belt guiding device, which includes a brake belt guiding device main body 1, a vertical guiding mechanism 2, a horizontal guiding mechanism 3, a strip brush device 4 and a displacement device 5.

[0045] The brake belt guiding device main body 1 is a cavity with open ends and a closed perimeter, which is used to provide a passing space for the brake belt.

[0046] The vertical guiding mechanism 2 and the displacement device 5 are respectively fixedly installed at both ends of the brake belt guiding device main body 1, and the horizontal guiding mechanism 3 is installed outside the displacement device 5. Among them, the horizontal guiding mechanism 3 is the inlet of the brake belt, and the vertical guiding mechanism 2 is the outlet of the brake belt. The displacement device 5 is used to adjust the angle between the inlet and outlet of the brake belt to be vertical or any angle, improve the tension of the brake belt, solve the problem of the brake belt jumping out of the groove, and ensure the stability of the movement process.

[0047] The strip brush device 4 is fixedly installed on the brake belt guiding device main body 1 and is located between the vertical guiding mechanism 2 and the displacement device 5. The strip brush device 4 is used to remove the sundries on the brake belt, effectively prevent the sundries from affecting the winding of the brake belt on the belt reel in the brake belt recovery device, and the unreliable factors during the recovery process.

[0048] As Figure 3 shown, the brake belt guiding device main body 1 includes a mounting base 101, an operation cover plate 102 and a nameplate 103.

[0049] The mounting base 101 is provided with a plurality of reserved mounting holes. An operation cover plate 102, a nameplate 103 and a brush device 4 are fixedly installed on the reserved mounting holes of the mounting base 101 through bolts. The operation cover plate 102 is used to provide a sufficient operation window for the disassembly and assembly of the brake band, the repair of the adjusting device, etc. The nameplate 103 is used to provide information such as the physical characteristics and performance of the device.

[0050] The bottom of the mounting base 101 is provided with a plurality of fixed mounting ports for the ground base.

[0051] Such as Figure 4 、 Figure 5 、 Figure 6 As shown, the vertical belt guiding mechanism 2 includes a vertical wear-resistant liner 201, a support shaft 202, a vertical belt guiding wheel cover plate 203, an end cover 204, a vertical belt guiding wheel 205, a vertical support shaft 206, a seal ring 207, a cover plate gasket 208, a vertical rotary seal ring 209, a vertical bearing 210 and a seal ring 211.

[0052] The vertical belt guiding wheel cover plate 203 is an upper cover plate and a lower cover plate arranged in parallel. The vertical belt guiding wheel 205 is installed between the upper cover plate and the lower cover plate of the vertical belt guiding wheel cover plate 203 through the vertical bearing 210 and the vertical support shaft 206. Vertical wear-resistant liners 201 are provided on the inner sides of the upper cover plate and the lower cover plate of the vertical belt guiding wheel cover plate 203, which are used for anti-wear protection during the movement of the brake band.

[0053] Seal ring installation grooves are provided at the bottom and the head of the vertical support shaft 206. The seal ring 207 is installed at the head of the vertical support shaft 206 and is matched with the end cover 204. The seal ring 211 is installed at the bottom of the vertical support shaft 206 and is matched with the lower cover plate of the vertical belt guiding wheel cover plate 203. The vertical support shaft 206 is used to enhance the bearing capacity of the brake band under heavy load conditions and improve the service life of the components, making the brake band more stable and reliable during the transmission and recovery movement.

[0054] The inner side of the end cover 204 is provided with a mounting groove for the cover plate gasket 208. The end cover 204 is fixed to the upper cover plate of the vertical belt guiding wheel cover plate 203 and presses the vertical support shaft 206, which is used to support and press the brake band, effectively preventing the brake band from generating power fluctuations and disengaging from the belt guiding wheel during the recovery process.

[0055] Vertical rotary seal rings 209 are respectively installed between the end cover 204 and the vertical belt guiding wheel 205, and between the base of the vertical support shaft 206 and the vertical belt guiding wheel 205.

[0056] In addition, the support shaft 202 is located at the bottom of the vertical belt guiding mechanism 2, and can be movably arranged as a whole with the brake band recovery device through anchor components such as anchor rings and mounting plates.

[0057] In this embodiment, there are three vertically guiding pulleys 205 with the same structure. There is a passing gap for the brake belt between the three vertically guiding pulleys 205. The three vertically guiding pulleys 205 are arranged in a triangle. Two of the vertically guiding pulleys 205 are arranged side by side at the belt outlet position of the vertical belt guiding mechanism 2. The brake belt enters the vertical belt guiding mechanism 2 from the main body 1 of the brake belt guiding device. After the brake belt is pressed against and bypasses one vertically guiding pulley 205, it passes through between the two vertically guiding pulleys 205 arranged side by side, and then is output from the belt outlet of the vertical belt guiding mechanism 2. The two vertically guiding pulleys 205 arranged side by side play a role in limiting the brake belt.

[0058] As Figure 3 , Figure 7 , Figure 8 shown in the figure, the horizontal belt guiding mechanism 3 includes a horizontal rotary seal ring 301, a horizontal bearing 302, a horizontal guiding pulley 303, a horizontal wear-resistant liner 304, a horizontal support frame 305, an end cover two 306 and an end cover three 307.

[0059] There are two horizontal support frames 305. The two horizontal support frames 305 are parallel to each other and perpendicular to the axis of the horizontal guiding pulley 303. Both ends of the horizontal guiding pulley 303 are installed between the two horizontal support frames 305 through the horizontal bearings 302.

[0060] Horizontal wear-resistant liners 304 are provided on the inner sides of the two horizontal support frames 305 to protect the brake belt during its movement.

[0061] The horizontal guiding pulley 303 is fixed to the two horizontal support frames 305 through the end cover two 306 and the end cover three 307. The end cover two 306 and the end cover three 307 press the horizontal bearing 302 through the horizontal rotary seal ring 301. The horizontal rotary seal ring 301 is arranged at both ends of the horizontal guiding pulley 303.

[0062] In this embodiment, there are two horizontal guiding pulleys 303 with the same structure. There is a passing gap for the brake belt between the two horizontal guiding pulleys 303. One of the horizontal guiding pulleys 303 is close to the belt inlet position of the horizontal guiding pulley 303, and the other horizontal guiding pulley 303 is close to the displacement device 5. The brake belt passes between the two horizontal guiding pulleys 303 and plays a role in being limited, effectively preventing the brake belt from generating power fluctuations and breaking away from the guiding pulley during the recycling process.

[0063] As Figure 8 , Figure 9 shown in the figure, the displacement device 5 includes a first displacement component 501 and a second displacement component 502.

[0064] The first displacement component 501 has a first hollow cylinder. The inner wall of the first hollow cylinder is provided with internal teeth. One end of the first hollow cylinder has a first rectangular flange and is fixedly connected to the main body 1 of the brake belt guiding device. The other end of the first hollow cylinder has a first annular flange and is fixedly connected to the second displacement component 502 by bolts.

[0065] The second displacement component 502 has a second hollow cylinder. One end of the second hollow cylinder has a second rectangular flange and is fixedly connected to the two horizontal support frames 305 of the horizontal belt guiding mechanism 3. The middle part of the outer wall of the second hollow cylinder has a second annular flange. External teeth meshing with the internal teeth of the first hollow cylinder are provided on the outer wall of the second hollow cylinder on the left side of the second annular flange, which plays a role in axially rotating limit; the second annular flange is fixedly connected to the first annular flange of the second displacement component 502 by bolts.

[0066] Arc-shaped holes with the same diameter are provided on the first annular flange of the first displacement component 501 and the second annular flange of the second displacement component 502. After the second displacement component 502 penetrates into the second displacement component 502, bolts pass through the arc-shaped holes to tightly connect the first displacement component 501 and the second displacement component 502, improving the meshing force between the internal teeth and the external teeth.

[0067] The displacement device 5 realizes adjusting the angle between the brake belt of the horizontal belt guiding mechanism 3 and the brake belt of the vertical belt guiding mechanism 2 by rotating the second displacement component 502 equipped with the horizontal belt guiding mechanism 3 by an appropriate angle and then penetrating it into the first displacement component 501 and fastening it together with the second displacement component 502, thereby enhancing the tension force of the brake belt.

[0068] The principle of the embodiment of the present invention is as follows:

[0069] First, the brake belt enters from the belt inlet of the horizontal belt guiding mechanism 3, sequentially passes between the two horizontal belt guiding wheels 303, the second displacement component 502 and the first displacement component 501, and then is limited by the two horizontal belt guiding wheels 303 when passing through the two horizontal belt guiding wheels 303, effectively preventing the brake belt from generating power fluctuations and disengaging from the belt guiding wheels during the recovery process.

[0070] Subsequently, the brake belt enters the main body 1 of the brake belt guiding device, then closely adheres to and bypasses a vertical belt guiding wheel 205 of the vertical belt guiding mechanism 2, passes between the two juxtaposed vertical belt guiding wheels 205, is limited by the two juxtaposed vertical belt guiding wheels 205, and is output perpendicular to the horizontal state from the belt outlet of the vertical belt guiding mechanism 2 and is connected to a barrier net, a barrier cable or other types of barriers.

[0071] When it is necessary to adjust the tension of the brake band, loosen the connecting bolt of the first displacement component 501 and the second displacement component 502, pull out the second displacement component 502 equipped with the horizontal tape guiding mechanism 3 from the internal teeth of the first displacement component 501, insert it into the first displacement component 501 after rotating an appropriate angle, so that the internal teeth of the first displacement component 501 mesh with the external teeth of the second displacement component 502, and the bolt passes through the arc-shaped hole to fasten the first displacement component 501 and the second displacement component 502 again, realizing that the central axes of the horizontal tape guiding wheel 303 and the vertical tape guiding wheel 205 form a vertical angle or an arbitrary angle, thereby making the inlet and outlet angles of the brake band vertical or at an arbitrary angle to increase the brake band tension, solving the problem of the brake band jumping out of the groove, ensuring the stability of the movement process, and meeting the requirements of different occasions and working conditions.

[0072] In the present invention, terms such as "installation", "connection", "attachment", "fixation" and the like shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "attachment" can be a direct attachment or an indirect attachment through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0073] The shapes of the components in the drawings are all schematic, and there is no exclusion of a certain difference from their actual shapes. The drawings are only used to illustrate the principle of the present invention and are not intended to limit the present invention.

[0074] Although the present invention has been disclosed in detail with reference to the drawings, it should be understood that these descriptions are merely exemplary and are not used to limit the application of the present invention.
