Description

Technical Field

[0001] This application relates to the field of training devices, and more specifically, to a low-resistance roller bearing type underwater escape training device and system. Background Technology

[0002] Before helicopter crew members officially take up their posts, they need to undergo underwater escape training. This training requires the use of underwater escape rotation training devices, which are now widely used in various countries for underwater escape training.

[0003] Currently, most common underwater escape rotation training devices are unpowered, relying on airbags for training through manual flipping. Only the brakes are pneumatic. This type of underwater escape rotation training device is labor-intensive and has poor training results. Later underwater escape rotation training devices adopted a method of using a pneumatic motor and gear meshing to drive the gear to rotate, thereby rotating the underwater test chamber connected to the gear. Although this structure uses a pneumatic method to provide rotational power to the underwater chamber, the motion resistance between the pneumatic motor and the gear is too large, which can easily cause jamming and make it difficult to meet the requirements for long-term stable and smooth operation of the test device. Utility Model Content

[0004] The purpose of this application is to provide a low-resistance roller bearing type underwater escape training device and system, which greatly reduces the operating resistance of the equipment and significantly improves the operational reliability by setting roller bearings to roll against and support the rotating gears.

[0008] In some alternative implementations, multiple pairs of arc-shaped gear connecting plates are also included. The rotating gear is composed of multiple arc-shaped gear segments arranged sequentially along the circumference. Each pair of gear connecting plates is located on both sides of the splicing end of two adjacent arc-shaped gear segments. Each pair of gear connecting plates is connected at both ends by at least one screw. The screws at both ends of each pair of gear connecting plates pass through the slots of the two adjacent arc-shaped gear segments and the gear connecting flange, respectively.

[0009] In some alternative embodiments, the two sides of the gearbox are connected to the two connecting plates by a plurality of reinforcing seats, the reinforcing seats including a first L-shaped plate and a second L-shaped plate respectively connected to the gearbox and the connecting plates, the first L-shaped plate and the second L-shaped plate being connected by bolts.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this application provides a low-resistance roller bearing type underwater escape training device, which includes an annular gear connecting flange 100, four simulation chamber connecting plates 240 connected to the inner wall of the gear connecting flange 100, a rotating gear 110 sleeved and connected to the outer peripheral wall of the gear connecting flange 100, two annular connecting plates 120 symmetrically arranged on both sides of the rotating gear 110, a gearbox 130 whose bottom is connected to the top of the two connecting plates 120 respectively, and six pairs of arc-shaped gear connecting plates 190. The four simulation chamber connecting plates 240 are used to connect the top, bottom and sides of the simulation test chamber respectively. A pneumatic motor 140 is connected to each end of both sides of the gearbox 130. Two rotatable power gears 141 are connected to the gear shaft within the gearbox 130. The two power gears 141 are connected one-to-one with the output shafts of two pneumatic motors 140. The two power gears 141 mesh with the rotating gears 110. Each connecting plate 120 is connected with two sets of roller bearings 150. Each set includes twenty roller bearings 150 arranged circumferentially along the connecting plate 120. The rotating gears 110 have protrusions on both sides forming gear bosses 160 extending circumferentially. The two sets of roller bearings 150 connected to each connecting plate 120 roll and press against the inner and outer circumferential walls of the protruding gear bosses 160 on one side of the rotating gears 110. The top of the gearbox 130 is connected with a lifting lug.

[0028] The inner circumferential wall of the rotating gear 110 is provided with a groove 170 extending circumferentially therein. The outer circumferential wall of the gear connecting flange 100 is fitted into the groove 170. The rotating gear 110 is composed of six arc-shaped gear segments 111 arranged sequentially along the circumference. Each arc-shaped gear segment 111 has a groove 170 on its inner wall. Each pair of gear connecting plates 190 is fitted to both sides of the splicing end of two adjacent arc-shaped gear segments 111. Two screws 180 are connected to both ends of each gear connecting plate 190 through fixing holes 191. Two first connecting holes 112 are provided, which penetrate into the slot 170. The gear connecting flange 100 is provided with six sets of second connecting holes 260 arranged circumferentially. Each set includes four second connecting holes 260 arranged circumferentially along the gear connecting flange 100. Two screws 180 connected to both ends of each gear connecting plate 190 pass through the first connecting holes 112 at the ends of two adjacent arc-shaped gear segments 111, a set of second connecting holes 260 on the gear connecting flange 100, and the fixing holes 191 at both ends of the corresponding gear connecting plate 190 in sequence.

[0029] The gearbox 130 is connected to the two connecting plates 120 on both sides by four reinforcing seats 200. Each reinforcing seat 200 includes a first L-shaped plate 210 and a second L-shaped plate 220 connected to the gearbox 130 and the connecting plate 120 respectively. The first L-shaped plate 210 and the second L-shaped plate 220 are connected by four bolts. Each second L-shaped plate 220 is also connected to two ribs 230. Each rib 230 is connected to both ends of the corresponding second L-shaped plate 220. Six reinforcing plates 121 are connected between the two connecting plates 120. The six reinforcing plates 121 are arranged circumferentially around the rotating gear 110. Each connecting plate 120 has sixteen weight-reducing holes 122 arranged circumferentially around it.

[0030] The working principle of the low-resistance roller bearing underwater escape training device provided in this application embodiment is as follows: four simulation chamber connecting plates 240 connected to the inner peripheral wall of the gear connecting flange 100 are welded and fixed to the top, bottom and sides of the simulation test chamber to complete the installation. Then, the low-resistance roller bearing underwater escape training device and the simulation test chamber are hoisted together into the training pool. Trainees can enter the simulation test chamber to conduct training. During training, two pneumatic motors 140 are started to drive two power gears 141 to rotate. The rotating power gears 141 drive the rotating gear 110 to rotate, so that the rotating gear 110 drives the simulation chamber connecting plate 240 and the simulation test chamber to rotate through the connected gear connecting flange 100, thereby conducting underwater escape training. Each connecting plate 120 is connected to two sets of roller bearings 150. The two sides of the rotating gear 110 are respectively raised to form gear bosses 160 extending circumferentially. When the rotating gear 110 drives the simulation chamber connecting plate 240 and the simulation test chamber to rotate, the two sets of roller bearings 150 connected to each connecting plate 120 roll and press against the inner and outer circumferential walls of the gear bosses 160 on one side of the rotating gear 110. In this way, the weight of the simulation test chamber is evenly borne by the four sets of roller bearings 150, which effectively reduces the running resistance when the simulation test chamber rotates and greatly improves the reliability and smoothness of operation.

[0031] Specifically, by installing a pneumatic motor 140 on each side of the gearbox 130 to drive two power gears 141 to rotate, thereby rotating the rotary gear 110, the stress on the top sides of the rotary gear 110 can be dispersed by the power gears 141 connected to the pneumatic motors 140 on both sides of the gearbox 130, ensuring that the two power gears 141 stably drive the rotary gear 110 to rotate. The rotary gear 110 is composed of six arc-shaped gear segments 111 arranged circumferentially. The inner circumferential wall of the rotary gear 110 is provided with a groove 170 extending circumferentially. The outer circumferential wall of the gear connecting flange 100 is engaged in the groove 170. A gear connecting plate 19 is provided on each side of the splicing end of two adjacent arc-shaped gear segments 111. Each gear connecting plate 190 has two screws 180 connected to both ends of each gear connecting plate 190 through fixing holes 191. The two screws 180 connected to both ends of each gear connecting plate 190 pass through the first connecting holes 112 at the ends of two adjacent arc-shaped gear segments 111, a set of second connecting holes 260 on the gear connecting flange 100, and the fixing holes 191 at both ends of the corresponding gear connecting plate 190 in sequence. This allows the six pairs of gear connecting plates 190 to be connected into a whole by the screws 180 passing through the ends of the six arc-shaped gear segments 111 and the gear connecting plates 190. This ensures the connection strength and operational stability of the rotating gear 110 and the gear connecting plate 190, while facilitating the transportation and loading / unloading of the rotating gear 110 and the gear connecting plate 190 by the operators.

[0032] The gearbox 130 is connected to the two connecting plates 120 on both sides by four reinforcing seats 200. Each reinforcing seat 200 includes a first L-shaped plate 210 and a second L-shaped plate 220 connected to the gearbox 130 and the connecting plate 120 respectively. The first L-shaped plate 210 and the second L-shaped plate 220 are connected by four bolts. Each second L-shaped plate 220 is also connected to two ribs 230. Each rib 230 is connected to both ends of the corresponding second L-shaped plate 220. The first L-shaped plate 210 and the second L-shaped plate 220 can be used to stably connect the gearbox 130 and the connecting plate 120 into a whole, thereby improving the overall structural strength and ensuring operational stability. Six reinforcing plates 121 are connected between the two connecting plates 120. The six reinforcing plates 121 are arranged at intervals along the circumference of the rotating gear 110. The reinforcing plates can improve the connection stability of the two connecting plates 120 and ensure that the two connecting plates 120 are stably wrapped around the outside of the rotating gear 110 and the gear connecting plate 190 for protection. Each connecting plate 120 has weight-reducing holes 122 arranged at intervals along its circumference to reduce the weight of the device and improve the operating stability of the device.

[0033] This application embodiment also provides a low-resistance roller bearing type underwater escape training system, which includes the above-mentioned low-resistance roller bearing type underwater escape training device and a simulation test chamber. The top, bottom and sides of the simulation test chamber are respectively connected to four simulation chamber connecting plates 240 on the inner wall of the gear connecting flange 100.

[0034] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
