Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of filling projectile, specifically relates to a retreat stop mechanism and stage type filling projectile launching device. BACKGROUND

[0002] The existing launching device usually uses an electric cylinder to send the filling projectile directly into the launcher from the filling bin for launching when launching the filling projectile, which makes the pushing and launching stroke of the electric cylinder too long, usually about two meters, and brings certain difficulty to the adjustment of the whole launching device, especially when adjusting the pitch angle. In order to overcome the above problems, the stage type launching device emerges as the times require. The stage type launching can divide the launching process of the filling projectile into two steps: in the first stage, the filling bin is aligned with the launcher, and the filling projectile is pushed from the filling bin to the launcher; in the second stage, the launching mechanism is aligned with the launcher, and the filling projectile is launched by the launching mechanism. In addition, the launching device needs to change the attitude according to the launching requirements, such as pitch and rotation. The attitude needs to be adjusted first, and then the filling projectile is launched, that is, the attitude adjustment and the launching process of the filling projectile are carried out in steps.

[0003] However, in the traditional stage type launching device, there are still some key problems to be solved: because no special retreat stop mechanism is set in the first stage pushing process, under the condition of large pitch angle or external force vibration, the filling projectile cannot be retained in the specified position in the launcher for launching, which causes positioning error, which not only affects the launching accuracy in the second stage, but also may cause launching failure. Secondly, although the stage type launching divides the launching process into two steps to solve the problem of long launching device difficult to adjust, it introduces the step of switching the filling bin and the launching mechanism, which reduces the overall launching efficiency of the device, especially it is difficult to adapt to the scene requiring rapid and continuous launching.

[0050] Example 1

[0051] A type of anti-reverse mechanism 412, such as Figures 1-4 As shown, it includes a retaining housing 4121 and a retaining block 4122.

[0052] The system comprises a support block 4123, an elastic element 4124, and a guide element 4125. The anti-reverse housing 4121 has an anti-reverse channel penetrating through it. An anti-reverse block 4122 is movably connected to one side of the anti-reverse channel, and a support block 4123 is fixedly connected to the other side. The top of the anti-reverse block 4122 is an anti-reverse end, and the bottom is a connecting end. The two opposite sides of the anti-reverse end in the thickness direction are a wedge-shaped surface and a vertical surface, respectively. One side of the guide element 4125 passes through the support block 4123 and connects to the connecting end of the anti-reverse block 4122; the other side has a limiting block that can restrict movement outside the anti-reverse channel. An elastic element 4124 is provided between the anti-reverse block 4122 and the support base. The anti-reverse block 4122 can retract into the anti-reverse channel under pressure, and when no external force is applied, the anti-reverse block 4122 can extend out of the anti-reverse channel under the action of the elastic element 4124. Preferably, the elastic element 4124 is a spring.

[0053] Specifically, the anti-reverse mechanism 412, through the cooperation of the elastic element 4124 and the guide element 4125, realizes the automatic extension and retraction of the anti-reverse block 4122 under force and non-force conditions, effectively ensuring the positional stability of the loading material during the launch process, and improving the launch accuracy and system reliability.

[0054] The anti-reverse end has symmetrical anti-reverse protrusions 4126 on both sides along its length, forming a concave structure.

[0055] Specifically, the concave structure of the retreat-preventing end can effectively reduce the contact area with the filling, ensuring smooth passage of the filling through the retreat-preventing end.

[0056] The connecting end is provided with a connecting hole, and the side of the guide piece 4125 matched with the retreat-preventing block 4122 can extend into the connecting hole and be threadedly connected with the connecting end.

[0057] Specifically, through the threaded connection, the connection between the guide piece 4125 and the retreat-preventing block 4122 is more stable, which can effectively avoid the loosening of the components caused by external force, and improve the durability and reliability of the entire retreat-preventing mechanism 412.

[0058] The side of the guide piece 4125 matched with the retreat-preventing block 4122 is provided with a limiting boss, and the limiting boss is limited outside the connecting hole.

[0059] Specifically, the limiting boss ensures the assembly precision of the guide piece 4125, prevents the guide piece 4125 from being excessively inserted or removed, and ensures the reliable operation of the retreat-preventing mechanism 412 in a complex launch environment.

[0060] The first-stage pushing guide piece 4125 is a circular shaft structure, and the support block 4123 is provided with a cylindrical hole for the guide piece 4125 to pass through.

[0061] The first-stage pushing guide piece 4125 is a circular shaft structure, and the support block 4123 is provided with a cylindrical hole for the guide piece 4125 to pass through.

[0062] The first-stage pushing guide piece 4125 is a circular shaft structure, and the support block 4123 is provided with a cylindrical hole for the guide piece 4125 to pass through.

[0063] Specifically, by symmetrically arranging the guide pieces 4125 in pairs, the stress on the retreat-preventing block 4122 is more uniform when the retreat-preventing block 4122 is in extension and contraction, reducing the occurrence of deviation and jamming, and improving the movement stability of the retreat-preventing block 4122 and the reliability of the overall structure.

[0064] Specifically, by symmetrically arranging the guide pieces 4125 in pairs, the stress on the retreat-preventing block 4122 is more uniform when the retreat-preventing block 4122 is in extension and contraction, reducing the occurrence of deviation and jamming, and improving the movement stability of the retreat-preventing block 4122 and the reliability of the overall structure.

[0065] The two ends of the retreat-preventing shell 4121 in the length direction are provided with supports 4127 for fixing the thrust shell to the installation base surface, and a plurality of mounting holes are arranged at the supports 4127.

[0066] Specifically, the retreat-preventing shell 4121 can be conveniently fixed to the installation base surface through the mounting holes on the supports 4127, ensuring the adaptability and installation convenience of the retreat-preventing mechanism 412 in various devices, and without interfering with the guide piece 4125 and the retreat-preventing block 4122.

[0067] Example 2

[0068] A staged loading launcher, such as Figures 1-12 As shown, the system includes the anti-reverse mechanism 412 as described in Embodiment 1, and also includes a first-stage pushing channel 21, a first-stage pushing drive device 1, a second-stage launching channel, a second-stage launching drive device 3, and an adjusting bracket 42. The second-stage launching channel is not shown in the figure. A loading port 411 is provided on the entrance side of the second-stage launching channel. The anti-reverse mechanism 412 is located at the loading port 411. The first-stage pushing channel 21 and the second-stage launching drive device 3 are arranged side by side on the adjusting bracket 42. The adjusting bracket 42 can drive one of the first-stage pushing channel 21 and the second-stage launching drive device 3 to match the loading port 411. When the first-stage pushing channel 21 matches the loading port 411, the first-stage pushing drive device 1 can drive the loading material in the first-stage pushing channel 21 to pass through the anti-reverse device and enter the second-stage launching channel. When the second-stage launching drive device 3 matches the loading port 411, the second-stage launching drive device 3 can act on the loading material in the second-stage launching channel. The loading material can be launched along the second-stage launching channel under the action of the second-stage launching drive device 3. To achieve continuous supply of the filling material, multiple first-stage push channels 21 are arranged circumferentially at intervals to form a filling chamber 2. The filling chamber 2 includes a first filling chamber 2 and a second filling chamber 2. The two filling chambers 2 are located on both sides of the second-stage launch drive device 3 to achieve dual-sided filling material supply. One side of the filling chamber 2 is a pushing side corresponding to the first-stage pushing drive device 1, and the other side is a receiving side corresponding to the filling port 411. The first-stage pushing drive device 1 can provide a pushing force for the filling material in the filling chamber 2, causing the filling material located on the pushing side to move to the receiving side and enter the filling port 411 corresponding to the receiving side. The first-stage pushing drive device 1 includes a one-way chain assembly 11, a guide rail 12, and a one-way chain drive unit 13. The guide rail 12 corresponds to the filling chamber 2. The one-way chain assembly 11 can extend or retract from the guide rail 12 under the action of the one-way chain drive unit 13. When the one-way chain assembly 11 is in the pushing state, it can extend and straighten from the guide rail 12. The extended end of the one-way chain assembly 11 can act on the filling material and push the filling material from the filling chamber 2 to the filling port 411. When the one-way chain assembly 11 is in the storage state, it can bend along the shape of the guide rail 12 and retract into the guide rail 12.

[0069] Specifically, by setting a backstop mechanism 412 at the loading port 411, it is possible to ensure that the loading material maintains an accurate position during each stage of the pushing process, making the pushing and launching operations in the first and second stages more precise and efficient, and improving the overall performance and reliability of the device.

[0070] The two sides of the length direction of the retreat prevention end are symmetrically provided with retreat prevention protrusions 4126 to form a concave- shaped structure, and the head end of the filling object is provided with a wedge-shaped surface matched with the retreat prevention end.

[0071] Specifically, when the filling object enters the filling port 411, the wedge-shaped surface can press down the retreat prevention block 4122 by matching with the retreat prevention end, and after the filling object passes through the filling port 411, the retreat prevention block 4122 is ejected to limit the retreat of the filling object.

[0072] The first-stage pushing further comprises a posture adjustment device 4 capable of performing pose adjustment, wherein the pose adjustment comprises one or more combinations of horizontal rotation, pitch adjustment, roll adjustment and translation adjustment, and the second-stage launching channel and the adjustment support 42 are arranged in the posture adjustment device 4. The posture adjustment device 4 is further provided with a connecting flange plate 41, the filling port 411 is arranged on the connecting flange plate 41, the connecting flange plate 41 is connected with the second-stage launching channel entrance, and the adjustment support 42 is movable relative to the connecting flange plate 41.

[0073] Specifically, the introduction of the posture adjustment device 4 enables the launching device to perform pose adjustment according to actual needs, greatly improves the adaptability and operation flexibility of the device in various complex environments, ensures that the filling object can be accurately launched at any angle and position, and improves the diversity and reliability of the launching effect. The filling object can be limited at the retreat prevention mechanism 412, so the first-stage pushing of the filling object can be performed while the posture is adjusted, achieving the effect of being mobile, flexible and time-saving.

[0074] When the first loading chamber needs to launch the loading material, the first loading chamber rotates to match the selected first-stage pushing channel 21 with the corresponding first-stage pushing driving device 1, the adjusting bracket 42 moves relative to the connecting flange plate 41 to make the loading end 211 of the selected first-stage pushing channel 21 in the first loading chamber correspond to the loading port 411 on the connecting flange plate 41, at this time, the one-way chain driving unit 13 of the first-stage pushing driving device 1 is started to drive the one-way chain assembly 11 to extend from the supplement end 212 of the first-stage pushing channel 21 and keep straight under the action of the elastic member to act on the loading material, so that the loading material moves from the loading end 211 of the first-stage pushing channel 21 to the loading port 411 of the connecting flange plate 41, when the loading material passes through the loading port 411, the stop mechanism 412 matches and is compressed by the head end of the loading material under the action of the thrust force to achieve elastic retreat, after the loading material passes through the loading port 411, the stop mechanism 412 can extend again under the action of the elastic force to limit the tail end of the loading material, so as to avoid the loading material from retreating during the pitch adjustment of the attitude adjustment device 4, after the loading material is moved into position, the one-way chain assembly 11 is retracted into the guide rail 12 under the action of the one-way chain driving unit 13, the adjusting bracket 42 moves relative to the connecting flange plate 41 to make the second-stage launching driving device 3 align with the loading port 411, the push rod 31 of the second-stage launching driving device 3 extends and acts on the loading material at the loading port 411 to quickly push the loading material into the second-stage launching channel for launching, after the launching is completed, the push rod 31 of the second-stage launching driving device 3 is retracted, when the first loading chamber launches the loading material, the second loading chamber rotates to match the selected first-stage pushing channel 21 with the corresponding first-stage pushing driving device 1, after the push rod 31 of the second-stage launching driving device 3 is retracted, the adjusting bracket 42 moves relative to the connecting flange plate 41 to make the loading end 211 of the selected first-stage pushing channel 21 in the second loading chamber correspond to the loading port 411 on the connecting flange plate 41, the rest of the process is the same as the process of launching the loading material by the first loading chamber, which will not be described here, in this way, the first loading chamber and the second loading chamber can alternately provide the loading material, more preferably, while one loading chamber 2 is launching the loading material, the other loading chamber 2 can simultaneously select the loading material, which effectively shortens the cycle time of launching the loading material. The above launching process is divided into two stages, the first stage provides a moving thrust for the first-stage pushing driving device 1 to make the loading material move from the supplement end 212 of the first-stage pushing channel 21 to the loading port 411 of the connecting flange plate 41, the second stage provides a launching thrust for the second-stage launching driving device 3 to make the loading material quickly move into the second-stage launching channel and press the launching device, which balances the pitch moment of the launching device and reduces the power of the whole machine.
