Description

Technical Field

[0001] The present application relates to a multi-rope telescopic device, and in particular to a multi-rope isotorque driven launching telescopic device, which belongs to the field of aircraft load release. Background Art

[0002] When the aircraft payload is released from the carrier platform, its own power or onboard power is required to push the payload out of the carrier platform. A release system with large load-bearing capacity and small size can provide effective protection for the payload launch. At present, the main power methods for payload release include the payload's own high-pressure gas, a multi-section rod installed on the carrier platform and driven by high-pressure gas, and a launch platform driven by a flexible rope. The method of launching using high-pressure gas is mostly one-time use, and generally has high sealing requirements for the container that bears the gas pressure. It is suitable for disposable payload carriers. The launch platform driven by a flexible rope is electrically driven and reusable. The launch platform driven by a flexible rope mainly uses a winding roller to pull the flexible rope to retract and release, thereby driving the launch platform to push out the load. The traditional flexible rope drive system uses a single or two ropes for drive. Summary of the invention

[0003] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, to provide an inter-stage self-locking and interlocking device, to solve the problem that a multi-stage rope-driven telescopic device is difficult to automatically unfold and fold in sequence; to use an equal-torque multi-rope driving device as a drive, to solve the problem of excessive bearing capacity of a single rope caused by multi-rope eccentric loading, and to improve the bearing capacity of the drive; the integrated driving device and the simple self-locking and interlocking device enable the telescopic device to have the advantages of high integration and large expansion and contraction ratio.

[0004] The technical solution of the present invention is:

[0005] A multi-rope equal-torque driven launching telescopic device comprises a plurality of telescopic sleeves which are sleeved in sequence from the inside to the outside, an interlocking device is arranged between any three adjacent telescopic sleeves, and the three adjacent telescopic sleeves are sequentially an inner telescopic sleeve, a middle telescopic sleeve and an outer telescopic sleeve from the inside to the outside;

[0006] The interlocking device includes a locking pin, an interlocking groove, a locking pin hole, and an elastic member.

[0007] The locking pin hole is opened on the outer telescopic sleeve.

[0008] The interlocking groove is set on the inner telescopic sleeve.

The elastic member gives the locking pin a thrust to move toward the outer telescopic sleeve.

[0010] The interlocking groove includes a first groove and a second groove which are sequentially connected along the expansion direction of the telescopic sleeve.

[0011] When the locking end is not facing the locking pin hole, the first groove limits the locking end so that the interlocking end is located in the interlocking groove;

[0012] When the locking end is facing the locking pin hole, the elastic member pushes the locking end to be inserted into the locking pin hole, and when the inner telescopic sleeve is extended, the interlocking end can be disengaged from the interlocking groove; when the inner telescopic sleeve is retracted, the interlocking end enters the first groove, and then under the guidance of the second groove, the interlocking end drives the locking end to move until it disengages from the locking pin hole.

[0013] There is a connecting section between the locking end and the interlocking end, and the outer diameter of the interlocking end is larger than the outer diameter of the connecting end.

[0015] The interlocking end is provided with a first tapered portion and a second tapered portion. Starting from the end of the connecting section, along the direction toward the inner telescopic sleeve, the outer diameter of the first tapered portion gradually increases, and starting from one end of the first tapered portion toward the inner telescopic sleeve, along the direction toward the inner telescopic sleeve, the outer diameter of the second tapered portion gradually decreases, and the maximum outer diameter of the second tapered portion is smaller than the maximum outer diameter of the first tapered portion.

[0016] The second groove is gradually inclined toward the inner telescopic sleeve along the extending direction of the telescopic sleeve to form a slope groove.

[0017] The interlocking groove further comprises a third groove, which is a straight groove connected to an end of the second groove away from the first groove, so that the interlocking end is stably located in the third groove.

[0018] The locking end includes a flange and an insertion portion. The outer diameter of the flange is not larger than the inner diameter of the through hole. The insertion portion is used to insert into the locking pin hole. The outer diameter of the flange is larger than the outer diameter of the insertion portion and is used to limit the insertion depth of the locking end in the locking pin hole. One end of the elastic member presses against the side wall of the through hole and the other end presses against one end of the flange facing the inner telescopic sleeve.

[0019] The insertion portion is in a tapered shape with a diameter gradually decreasing along a direction away from the axis of the inner telescopic sleeve.

[0020] The multiple telescopic sleeves that are sleeved in sequence from the inside to the outside include an innermost top-level telescopic sleeve, an outermost final-level telescopic sleeve, and an intermediate-level telescopic sleeve between the top-level telescopic sleeve and the final-level telescopic sleeve, the top of the final-level telescopic sleeve is rotatably connected to a final-level top wire wheel, the bottom of the intermediate-level telescopic sleeve is rotatably connected to an intermediate-level bottom wire wheel, the top is rotatably connected to an intermediate-level top wire wheel, and the bottom of the top-level telescopic sleeve is rotatably connected to a top-level bottom wire wheel;

[0054] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0056] An inter-stage self-locking and interlocking device C-5, such as Figure 1 As shown, it includes a telescopic driving device A, a telescopic structure body, an interlocking device C-5, and a flexible rope.

[0057] like Figure 1-Figure 5 As shown, the telescopic structure body includes a plurality of telescopic sleeves which are sequentially sleeved from the inside to the outside.

The bottom wire wheel of the telescopic sleeve is mounted on the bottom flange, and the top wire wheel is mounted on the top flange of the top wire wheel. Except for the top telescopic sleeve, each telescopic sleeve has a locking pin hole near the top.

[0058] In any two adjacent telescopic sleeves, the outer wall of the inner telescopic sleeve is provided with an intermediate guide rail C-7, and the top flange of the outer telescopic sleeve is connected with a groove matching the intermediate guide rail C-7, ensuring that the telescopic sleeves will not rotate relative to each other.

[0059] like Figure 1 and Figure 3 As shown, the telescopic drive device A is a multi-rope isotorque drive device based on a differential gear system, comprising a pull-back reversing guide wheel group, a pull-back reel, a power distribution gear group, a differential gear system torque distributor, a motor, a launch reel, and a launch reversing guide wheel group. The pull-back reversing guide wheel group is fixedly connected to the housing, the pull-back reel is fixedly connected to the pull-back power output gear on the power distribution gear group, and is connected to the housing through a rotating pair. The power distribution gear group is fixedly connected to the pull-back reel and the differential gear system torque distributor, respectively, and forms two gears with the gear on the motor. The gear pair, the motor is fixedly connected to the housing, the three launching reels are evenly arranged in the circumference, connected to the housing through a rotating pair, and connected to the differential gear system torque distributor through different gear pairs, the launching reversing guide wheel group is fixedly connected to the housing, the pull-back flexible rope is reversingly wound on the pull-back reel through the pull-back reversing guide wheel group, the launching flexible rope is reversingly wound on the pull-back reel through the launching reel, the pull-back flexible rope is fixed to the buffer device at the bottom of the top telescopic sleeve F, and the launching flexible rope is fixed to the buffer device at the top of the top telescopic sleeve F. The telescopic drive device A is located inside the final telescopic sleeve B, and the bottom of the final telescopic sleeve B is connected to the base of the telescopic fixing device.

[0060] The telescopic drive device can also be: multiple motors are respectively connected to the launching reels for individual driving, and equal torque driving is achieved by relying on a control algorithm.

[0061] like Figure 6 and Figure 7As shown, an interlocking device C-5 is provided between any three adjacent telescopic sleeves, and the three adjacent telescopic sleeves are, from inside to outside, an inner telescopic sleeve 1, a middle telescopic sleeve 2, and an outer telescopic sleeve 3. The interlocking device C-5 includes a locking pin 5, an interlocking groove C-6, a locking pin hole, and an elastic member; the locking pin hole is provided in the outer telescopic sleeve 3; the interlocking groove C-6 is provided in the inner telescopic sleeve 1; the middle telescopic sleeve 2 is connected with an adapter box C-5-3, and the adapter box C-5-3 is provided with a through hole, and the locking pin 5 is connected to the middle telescopic sleeve 2 through the through hole, and the elastic member gives the locking pin 5 a thrust to move outward toward the telescopic sleeve, and one end of the locking pin 5 is provided with a locking end C-5-2 for inserting into the locking pin hole, and the other end is provided with an interlocking end C-5-1 that cooperates with the interlocking groove C-6 for interlocking; the interlocking groove C-6 includes a first groove 42, a second groove 43, and a third groove 44 that are sequentially connected along the expansion direction of the telescopic sleeve.

[0062] like Fig. 9 and Figure 11-Figure 14 As shown, the outer wall of the inner telescopic sleeve 1 is connected with an interconnecting portion, and the interlocking groove C-6 also includes an insertion groove 41, which is opened in the interconnecting portion. The width of the insertion groove 41 matches the outer diameter of the connecting section C-5-5, and the insertion groove 41 has a closed end at one end along the extending direction of the telescopic sleeve and an open end at the other end opposite to the extending direction of the telescopic sleeve, so that the connecting end can be inserted into the insertion groove 41 and the interlocking end C-5-1 can enter the first groove 42.

[0063] The first groove 42 is inclined opposite to the inner wall of the extending groove 41, and the inclination direction is: along the extension direction of the telescopic sleeve, gradually inclined toward the inner telescopic sleeve 1. The second groove 43 is inclined along the extension direction of the telescopic sleeve, gradually inclined toward the inner telescopic sleeve 1, without forming a ramp groove. The third groove 44 is a straight groove connected to the end of the second groove 43 away from the first groove 42, so that the interlocking end C-5-1 is stably located in the third groove 44.

[0064] like Figure 8 and Fig. 9 As shown, the locking pin 5 has the following structure: the locking end C-5-2 is a cylindrical oblique cone pin with a flange, the interlocking end C-5-1 is a relatively double cone shape at the bottom, and the middle is cylindrical, and the interlocking groove C-6 has the following structure: the lower half is a ramp groove, and the upper half is a straight groove. The exit position of the interlocking groove C-6 is slightly higher, and the spring C-5-4 is coaxially placed on the outside of the cylindrical section of the locking pin 5.

[0065] Specifically, there is a connecting section C-5-5 between the locking end C-5-2 and the interlocking end C-5-1, and the connecting section C-5-5 is a cylindrical section. The outer diameter of the interlocking end C-5-1 is larger than the outer diameter of the connecting end. The interlocking end C-5-1 is provided with a first tapered portion 511 and a second tapered portion 512. Starting from the end of the connecting section C-5-5, along the direction toward the inner telescopic sleeve 1, the outer diameter of the first tapered portion 511 gradually increases, and starting from one end of the first tapered portion 511 toward the inner telescopic sleeve 1, along the direction toward the inner telescopic sleeve 1, the outer diameter of the second tapered portion 512 gradually decreases, and the maximum outer diameter of the second tapered portion 512 is smaller than the maximum outer diameter of the first tapered portion 511. The locking end C-5-2 includes a flange 521 and an insertion portion 522. The outer diameter of the flange 521 is not greater than the inner diameter of the through hole. The insertion portion 522 is used to be inserted into the locking pin hole. The outer diameter of the flange 521 is greater than the outer diameter of the insertion portion 522, which is used to limit the insertion depth of the locking end C-5-2 in the locking pin hole. One end of the elastic member presses against the side wall of the through hole and the other end presses against the end of the flange facing the inner telescopic sleeve 1. The insertion portion 522 is a cone with a diameter gradually decreasing along the direction away from the axis of the inner telescopic sleeve 1.

[0066] like Figure 1 As shown, the flexible rope has the following winding order: one end of the launching flexible rope is connected to the telescopic drive device A, and then is wound on the reel in the order of the last-stage top reel, the first intermediate-stage bottom reel C-2, the first intermediate-stage top reel, the second intermediate-stage bottom reel C-2, the second intermediate-stage top reel, the third intermediate-stage bottom reel C-2, and the third intermediate-stage top reel; the other end of the launching flexible rope is fixed to the buffer device at the top of the top-level telescopic sleeve F; one end of the pulling back flexible rope is connected to the telescopic drive device A, and the other end is fixed to the buffer device at the bottom of the top-level telescopic sleeve F.

[0067] The multi-rope equal-torque driven launching telescopic device can realize the function of repeated sequential expansion and contraction of multi-stage telescopic sleeves under single-degree-of-freedom input multi-rope equal-torque drive. Its working process is as follows: in the initial state, the telescopic device is in a contracted state. At this time, except that there is no mutual interlocking between the last stage and the first intermediate stage, the other two adjacent stages are interlocked by the locking pin 5 installed on the intermediate stage and the inner stage interlocking groove C-6, so that the two cannot slide arbitrarily in the axial direction. During the expansion process, the motor drives the wire roller to start winding the wire. Except for the last-stage telescopic sleeve B, the other telescopic sleeves are locked with each other. Therefore, the first intermediate stage to the top telescopic sleeve F are extended together. When the first intermediate stage telescopic sleeve C moves to the position where the locking pin and the lock hole coincide, the spring C-5-4 pushes the locking pin to move radially outward along the sleeve, and the locking pin falls into the lock hole and falls off from the interlocking groove C-6 of the second intermediate telescopic sleeve 2, thereby completing the locking with the previous stage and releasing the interlocking with the next stage. Similarly, the next stage continues to extend until it is fully extended.

[0068] The interlocking process is described as follows: an interlocking pin is installed on the middle telescopic sleeve 2, and the compression spring C-5-4 presses the interlocking pin to one side of the outer telescopic sleeve 3, but due to the limitation of the cylinder wall of the outer telescopic sleeve 3, the interlocking pin cannot slide. At this time, the other end of the interlocking pin is in the interlocking groove C-6 of the inner telescopic sleeve. At this time, the first groove 42 limits the interlocking pin in the vertical direction, so that when the inner telescopic sleeve 1 moves up, the middle telescopic sleeve 2 is driven to move up through the first groove 42 and the interlocking pin, thereby achieving interlocking;

[0069] The locking end C-5-2 is initially squeezed into the interlocking groove. Due to the force of the spring C-5-4, when the inner telescopic sleeve 1 moves upward until the locking pin hole is directly opposite to the locking pin 5, the locking pin 5 is ejected by the spring and inserted into the locking pin hole, thereby achieving locking. The exit position of the interlocking groove C-6 is slightly higher, so that the locking pin 5 cannot pass this position before being inserted into the locking pin hole, thereby ensuring that only one stage can be extended, preventing the various stages from being disengaged when retracted or the order from being disordered when extended. Conversely, when the outer telescopic sleeve 3 moves downward, the conical surface of the locking pin 5 cooperates with the ramp groove (i.e., the second groove 43) of the interlocking groove C-6, pulling the locking pin 5 to the left, and finally making the locking pin 5 stay in the straight section (i.e., the third groove 44) of the interlocking groove C-6.

[0070] Although the present invention is disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims of the present invention.
