Description

Technical Field

[0001] This utility model belongs to the technical field of rocket recovery devices, specifically relating to a chain-type recovery device. Background Technology

[0002] A rocket recovery system is a device used to recover the first stage or other parts of a rocket, with the aim of safely returning the rocket to Earth for reuse after launch. This system ensures controlled descent and precise landing, reduces launch costs, and increases launch frequency and efficiency.

[0003] When recovering rocket devices, different recovery equipment is often required for rocket devices of different sizes, which makes the adjustment process complicated. At the same time, when the rocket device lands, the landing point often deviates from the preset point, which makes it difficult to make temporary adjustments and increases the risk of recovery failure. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention provides a chain-type recovery device. This invention utilizes double-row sprockets and single-row sprockets in conjunction with a first and second slide, respectively. This enables the recovery of rocket devices of different sizes and allows for rapid adjustments based on the landing location of the rocket device, thereby improving recovery accuracy and preventing recovery failure. Furthermore, by fixing the first and second chain connectors to different sides of the chain, a single drive motor enables adjacent first and second slides to move synchronously towards or away from the double-row sprockets. This ensures that the intersection of the steel wire ropes is along the diagonal of the steel frame, ultimately achieving precise landing and recovery of rocket devices of different sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A chain-type recycling device includes a steel frame with columns fixedly mounted at the four bottom corners; double-row sprockets rotatably connected to the four top corners of the steel frame; two single-row sprockets rotatably connected to each side of the steel frame; the two sprockets of each double-row sprocket are respectively connected to corresponding single-row sprockets on adjacent side frames via chain drive; and drive motors are installed at the bottom of each of the four corners of the steel frame, with the output shafts of the drive motors fixedly connected to the shafts of the corresponding double-row sprockets. Two chains connected to the double-row sprocket drive have a first slide and a second slide fixedly connected to their inner sides, respectively; the first slide is fixedly connected to another first slide on the steel frame by a first steel wire rope; the second slide is fixedly connected to another second slide on the steel frame by a second steel wire rope; the first and second steel wire ropes form a grid structure.

[0006] Furthermore, a first chain connector and a second chain connector are respectively fixedly provided at the bottom of the first slide and the second slide; the first chain connector and the second chain connector are respectively fixed on different sides of the inner and outer sides of the chain.

[0007] Furthermore, the first chain connector is fixed to the inside of the chain, and the second chain connector is fixed to the outside of the chain.

[0008] Furthermore, guide rails are provided above the frame edges of the steel frame, and sliders are fixedly provided at the bottom of the first and second slides, with the sliders slidably connected to the corresponding guide rails.

[0009] Furthermore, a first guide rail is fixedly installed on the edge of the steel frame located below the first slide, and the first guide rail is slidably connected to the slider at the bottom of the first slide above.

[0010] Furthermore, a second guide rail is fixedly installed on the edge of the steel frame located below the second slide, and the second guide rail is slidably connected to the slider at the bottom of the upper second slide.

[0011] Furthermore, chain guide grooves are fixedly provided on the frame edge of the steel frame, and the chains are all located in the corresponding chain guide grooves.

[0012] Furthermore, a first chain guide groove is fixedly provided on the frame edge of the steel frame located below the first slide, and the chain below the first slide is located in the first chain guide groove.

[0013] Furthermore, a second chain guide groove is fixedly provided on the frame edge of the steel frame located below the second slide, and the chain below the second slide is located in the second chain guide groove.

[0014] Furthermore, multiple bearings are fixedly connected to the shaft of the double-row sprocket, and the single-row sprocket is fixedly installed on the corresponding bearing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model, through the cooperation of double-row sprockets and single-row sprockets with the first slide and the second slide respectively, can not only realize the recovery of rocket devices of different sizes, but also temporarily and quickly adjust according to the landing position of the rocket device, thereby improving the recovery accuracy and preventing recovery failure; specifically, by controlling the operation of the drive motor, the drive motor drives the double-row sprockets to rotate, thereby making the chain connected to the double-row sprocket drive rotate synchronously; at this time, the first slide and the second slide will move synchronously with the chain, and because the first slide and the other slide on the steel frame are opposite to each other, One sliding platform is fixedly connected by a first steel wire rope, and the second sliding platform is fixedly connected to another second sliding platform on the steel frame by a second steel wire rope. Therefore, the four steel wire ropes in the steel frame form a grid structure, and the size of the wellhead can be quickly adjusted, making it suitable for the landing and recovery of rocket devices of different sizes. At the same time, by controlling the running direction of different drive motors, the wellheads of the four steel wire ropes can be finely adjusted on the diagonal of the steel frame, which can also be temporarily and quickly adjusted according to the landing location of the rocket device, improving the recovery accuracy and preventing recovery failure.

[0016] (2) This utility model uses a first chain connector and a second chain connector to be fixed on different sides of the chain, so that the adjacent first slide and second slide can move synchronously toward or away from the double-row sprocket by a single drive motor. This ensures that the intersection of the wire ropes is along the diagonal of the steel frame, thus achieving precise landing and recovery of rocket devices of different sizes. Specifically, since the first chain connector is fixed on the inner side of the chain and the second chain connector is fixed on the outer side of the chain, when the double-row sprocket rotates, the adjacent first slide and second slide can move synchronously toward or away from the double-row sprocket. In this way, the intersection of the wire ropes is always along the diagonal of the steel frame, thus achieving precise landing and recovery of rocket devices of different sizes.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example like Figures 1-7 As shown, a chain-type recycling device includes a steel frame 50, with columns 51 fixedly installed at the four bottom corners of the steel frame 50; double-row sprockets 30 are rotatably connected to the four top corners of the steel frame 50; two single-row sprockets 90 are rotatably connected to each side of the steel frame 50; the two sprockets of the double-row sprockets 30 are respectively connected to the corresponding single-row sprockets 90 on the adjacent side of the frame via chain drive; drive motors are installed at the bottom of the four corners of the steel frame 50, and the output shafts of the drive motors are fixedly connected to the shafts of the corresponding double-row sprockets 30. Two chains, which are connected to the double-row sprockets 30, are respectively fixedly connected to the inner sides of a first slide 81 and a second slide 82; the first slide 81 is fixedly connected to another first slide 81 on the steel frame 50 by a first steel wire rope 70; the second slide 82 is fixedly connected to another second slide 82 on the steel frame 50 by a second steel wire rope 60; the first steel wire rope 70 and the second steel wire rope 60 form a grid-like structure.

[0021] This invention, through the cooperation of double-row sprockets 30 and single-row sprockets 90 with the first slide 81 and the second slide 82 respectively, can achieve the recovery of rocket devices of different sizes, and can also make temporary and rapid adjustments according to the landing location of the rocket device, thereby improving recovery accuracy and preventing recovery failure. Specifically, by controlling the operation of the drive motor, the drive motor drives the double-row sprockets 30 to rotate, thereby causing the chain connected to the double-row sprockets 30 to rotate synchronously. At this time, the first slide 81 and the second slide 82 will move synchronously with the chain, and because the first slide 81 and the other slide 82 on the steel frame 50 are opposite each other... A sliding platform 81 is fixedly connected by a first steel wire rope 70, and a second sliding platform 82 is fixedly connected to another second sliding platform 82 on the steel frame 50 via a second steel wire rope 60. Therefore, the four steel wire ropes in the steel frame 50 form a grid structure, and the size of the wellhead can be quickly adjusted, making it suitable for the landing and recovery of rocket devices of different sizes. At the same time, by controlling the running direction of different drive motors, the wellheads of the four steel wire ropes can be finely adjusted on the diagonal of the steel frame 50, which can also be temporarily and quickly adjusted according to the landing location of the rocket device, improving the recovery accuracy and preventing recovery failure.

[0022] It is worth noting that the drive motor of this utility model is powered by an external power source and can be a forward and reverse rotating motor. Since this is existing conventional technology, it is not shown in the accompanying drawings and will not be described in detail here.

[0023] Furthermore, the bottom of the first slide 81 and the second slide 82 are respectively fixedly provided with a first chain connector 42 and a second chain connector 41; the first chain connector 42 and the second chain connector 41 are respectively fixed on different sides of the inner and outer sides of the chain.

[0024] This invention uses a first chain connector 42 and a second chain connector 41, which are respectively fixed to the inner and outer sides of the chain. This allows adjacent first slides 81 and second slides 82 to move synchronously towards or away from the double-row sprocket 30 using a single drive motor. This ensures that the intersection of the wire ropes is along the diagonal of the steel frame 50, thereby achieving precise landing and recovery of rocket devices of different sizes. A detailed description follows.

[0025] Furthermore, the first chain connector 42 is fixed to the inner side of the chain, and the second chain connector 41 is fixed to the outer side of the chain.

[0026] Because the first chain connector 42 is fixed to the inner side of the chain and the second chain connector 41 is fixed to the outer side of the chain, when the double-row sprocket 30 rotates, the adjacent first slide 81 and second slide 82 can move synchronously towards or away from the double-row sprocket 30. In this way, the intersection of the wire ropes is always along the diagonal of the steel frame 50, thereby ultimately achieving precise landing and recovery of rocket devices of different sizes.

[0027] Furthermore, guide rails are provided above the frame edges of the steel frame 50, and sliders are fixedly provided at the bottom of the first slide table 81 and the second slide table 82, with the sliders slidably connected to the corresponding guide rails.

[0028] This invention improves the stability of the operation of the first slide 81 and the second slide 82 through the structural design of the slider and guide rail.

[0029] Furthermore, a first guide rail 10 is fixedly installed on the frame edge of the steel frame 50 located below the first slide table 81, and the first guide rail 10 is slidably connected to the slider at the bottom of the upper first slide table 81.

[0030] Furthermore, a second guide rail 20 is fixedly installed on the edge of the steel frame 50 located below the second slide table 82, and the second guide rail 20 is slidably connected to the slider at the bottom of the upper second slide table 82.

[0031] Furthermore, chain guide grooves are fixedly provided on the frame edge of the steel frame 50, and the chains are all located in the corresponding chain guide grooves.

[0032] This invention, through the structural design of the chain guide groove, can prevent the chain from sagging, thereby further improving operational stability and preventing equipment failure.

[0033] Furthermore, a first chain guide groove 92 is fixedly provided on the frame edge of the steel frame 50 located below the first slide table 81, and the chain below the first slide table 81 is located in the first chain guide groove 92.

[0034] Furthermore, a second chain guide groove 91 is fixedly provided on the frame edge of the steel frame 50 located below the second slide table 82, and the chain below the second slide table 82 is located in the second chain guide groove 91.

[0035] Furthermore, such as Figures 8-9As shown, multiple bearings are fixedly connected to the shaft of the double-row sprocket 30, and the single-row sprocket 90 is fixedly mounted on the corresponding bearing. With this structural design, when the motor drives the shaft of the corresponding double-row sprocket 30 to rotate, the corresponding single-row sprocket 90 on the bearing remains fixed due to the bearing structure. The rotation of the double-row sprocket 90 mounted on it drives the corresponding single-row sprocket 90 on the other side of the bearing to rotate, thereby driving the slide table on the chain to move.

[0036] This structural design allows the first slide 81 and the second slide 82 to move over a wider range, enabling the intersection of the first wire rope 70 and the second wire rope 60 to reach the corner position, thus preventing the rocket device from deviating too far from its target position during landing and causing collection failure.

[0037] like Figures 10-12 As shown, when the drive shaft rotates clockwise, the left slide is fixed to the outside of the chain, and the right slide is fixed to the inside of the chain, achieving simultaneous forward movement of both slides driven by the same motor. The chain-type recycling device uses four motors to drive four drive shafts to rotate. The four layers of sprockets are assembled on the same rotating shaft. Each drive shaft consists of a double-row drive shaft sprocket, a single-row driven shaft sprocket, and a double-row drive shaft sprocket, as shown in the diagram. Figure 12 As shown.

[0038] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
