Description

Technical Field

[0001] This invention relates to the field of guide channel cover plates, and more specifically, to a guide channel cover plate. Background Technology

[0002] The launch pad of a carrier rocket has a deflector channel on top. This channel serves several purposes: venting the combustion gases, buffering, protecting the environment, and cooling the rocket. It prevents backfire or the combustion gases from impacting ground facilities, thus protecting both the rocket and ground equipment. Specifically, the deflector channel guides the combustion gases generated during rocket ignition to the outside of the launch pad, preventing high-temperature gases from damaging launch equipment and the rocket's tail. The deflector channel typically contains a large amount of water. When the high-temperature flames encounter water, they form a white mist. This mist not only cools the rocket but also absorbs some sound energy, reducing the impact noise of the combustion gases. The deflector channel is usually equipped with a cover to facilitate personnel standing and inspecting the rocket.

[0003] Existing guide channel covers are often integrated into a single unit, which can take up considerable space and is cumbersome to move and open, reducing efficiency and potentially impacting worker productivity. Therefore, we propose a new guide channel cover design. Summary of the Invention

[0004] To solve the above problems, the present invention provides a guide channel cover plate, which adopts the following technical solution:

[0005] A flow guide channel cover plate includes a platform, a flow guide channel body is formed at the top of the platform, slide rails are fixedly installed on the inner walls of both sides of the flow guide channel body, two cover plate bodies are provided between the two slide rails in a symmetrical arrangement, the cover plate body includes two support plates fixedly installed between the two slide rails, a movable plate is provided on the opposite side of the two support plates, two sets of symmetrically distributed horizontal plates are slidably installed between the two slide rails, at least three horizontal plates in the same set are located between the support plates and the movable plates on the same side, a connecting plate is provided between the movable plate on the same side and an adjacent horizontal plate, between the support plate and an adjacent horizontal plate, and between two adjacent horizontal plates on the same side, two symmetrically distributed movable wheels are provided at the bottom of the horizontal plates and the movable plates, the movable wheels on the same side are located in the slide rail on the same side, a driving assembly is provided between the two movable plates and the slide rails, and a first shrinking structure and a second shrinking structure are provided between the two movable plates;

[0006] The inner walls on both sides of the guide channel body are provided with storage slots, and each of the two storage slots is provided with a support component.

[0007] By adopting the above technical solution, when the device is in use, the cover plate body is assembled by hinges using existing technology, consisting of a movable plate, a connecting plate, a horizontal plate, and a support plate. It has telescopic properties. The movable plate on the same side is driven to slide within the slide rail by the drive assembly. The movable plate pushes the connecting plate and the horizontal plate on the same side to slide, which can retract the cover plate body and facilitate the opening of the guide channel body. Both the movable plate and the horizontal plate are equipped with movable wheels at the bottom to facilitate their sliding within the slide rail. When it is necessary to close the guide channel body, the movable plate is driven to slide between the two slide rails by the drive assembly. The movable plate pulls the horizontal plate and the connecting plate on the same side to move, thereby closing the two movable plates and sealing the guide channel body. A first shrinking assembly and a second shrinking assembly are provided between the two movable plates to fix and shrink the two movable plates.

[0008] Once the two cover plates are locked, the support assembly moves to the bottom of the two cover plates and contacts the bottom of the cover plates, thus supporting and stabilizing the cover plates and improving their load-bearing capacity.

[0009] Furthermore, the drive assembly includes a toothed block plate fixedly installed in two slide rails. Two symmetrically distributed mounting seats are fixedly installed at the bottom of each of the two movable plates. The mounting seats have an "L"-shaped cross-section. A geared motor is fixedly installed at the top of the horizontal section of each mounting seat. The output shaft of the geared motor is connected to a reducer. Gears are sleeved on the sidewalls of the reducer shafts. Each reducer is fixedly connected to the opposite side of the horizontal section of the mounting seat on the same side. The two gears on the same side mesh with the toothed block plate on the same side. Slide grooves are opened on the inner walls of both sides of the guide channel body. Two symmetrically distributed sliders are slidably installed in each of the two slide grooves. The two sliders are fixedly connected to the opposite side of the two mounting seats on the same side.

[0010] By adopting the above technical solution, the geared motor drives the reducer on the same side to rotate, the reducer drives the gear on the same side to rotate, the gear meshes with the toothed block plate on the same side, the geared motor and the reducer are both fixed to the mounting base on the same side, and the mounting base is fixed to the bottom end of the moving plate on the same side. When the geared motor drives the gear on the same side to rotate, the toothed block plate is fixedly connected to the inner side of the slide rail on the same side. The moving plate slides between the two slide rails under the action of the driving force, thereby causing the moving plate to push the horizontal plate and the connecting plate on the same side to contract or extend, which can achieve the function of closing or opening the guide channel body.

[0011] Furthermore, the first shrinking assembly includes two first mounting plates fixedly installed on the top of one of the movable plates, a clamping plate rotatably installed between the two first mounting plates, two symmetrically distributed second mounting plates fixedly installed on the top of the other movable plate, a positioning rod fixedly installed between the two second mounting plates, a handle fixedly installed on the top of the clamping plate, a positioning groove opened at the bottom of the clamping plate, and grooves opened on the side of the two first mounting plates near the second mounting plates.

[0012] By adopting the above technical solution, when the two movable plates move relative to each other, the first mounting plate and the second mounting plate move relative to each other. When the two movable plates come into contact, the positioning rod installed between the two second mounting plates pushes the clamping plate located between the two first mounting plates to rotate, thereby causing the clamping plate to rotate upward between the two first mounting plates. Subsequently, when the positioning rod moves between the two first mounting plates, the clamping plate descends under the action of gravity, causing the positioning rod to engage with the positioning groove opened at the bottom of the clamping plate, which can fix the two movable plates and help maintain the stability of the two cover plate bodies. When it is necessary to retract the two cover plate bodies, the operator pulls the clamping plate by the handle, thereby causing the positioning groove opened at the bottom of the clamping plate to disengage from the positioning rod, and then the two cover plate bodies can be retracted.

[0013] Furthermore, the second shrinking assembly includes two first support blocks fixedly installed on the top of one of the movable plates, and two second support blocks symmetrically distributed fixedly installed on the top of the other movable plate. The tops of the first and second support blocks are provided with through holes, and a fixing pin is provided between the first and second support blocks on the same side.

[0014] By adopting the above technical solution, the height of the second support block is lower than that of the first support block. When the two movable plates are attached, the second support block moves to the bottom of the first support block on the same side. Then, the worker places the fixing pin in the through hole opened on the side wall of the first and second support blocks on the same side, which can further fix the two movable plates. When it is necessary to shrink the cover plate body, the worker can remove the fixing pin.

[0015] Furthermore, the support assembly includes a support plate slidably installed in the two storage slots. The cross-section of the two support plates is "L" shaped. Multiple cylinders arranged in a linear array are fixedly installed on the inner wall of opposite sides of the two storage slots. The piston shafts of the cylinders on the same side are fixedly connected to the side opposite to the vertical section of the support plate on the same side. A stabilizing plate is provided above the horizontal section of the two support plates. Multiple first telescopic rods arranged in a rectangular array are provided at the top of the horizontal section of the two support plates. The top ends of the first telescopic rods on the same side are fixedly connected to the bottom end of the stabilizing plate on the same side. Mounting slots are provided on both sides of the two stabilizing plates, and fixing components are provided in the mounting slots.

[0016] By adopting the above technical solution, after the two cover plates are closed, the cylinder drives the same-side support plate to move the stabilizing plate to the outside of the same-side receiving groove. Then, the first telescopic rod drives the stabilizing plate to rise, so that the stabilizing plate contacts the bottom of the cover plate body. Through the cooperation of the two stabilizing plates, the cover plate body is supported and stabilized, which helps to improve the load-bearing capacity of the cover plate body. In addition, a fixing component is provided between the stabilizing plate and the guide groove body to fix the stabilizing plate and help maintain the stability of the stabilizing plate in use.

[0017] Furthermore, each of the mounting slots is slidably installed with a fixing plate, and two symmetrically distributed second telescopic rods are fixedly installed on the inner wall of the two mounting slots on the same side. The ends of the two second telescopic rods on the same side are fixedly connected to the side opposite to the fixing plate on the same side. The inner wall of the guide channel body is provided with a fixing groove that matches the fixing plate on the same side.

[0018] By adopting the above technical solution, when the stabilizing plate is attached to the bottom of the cover plate body, the second telescopic rod drives the fixing plate on the same side to move to the outside of the mounting groove on the same side, so that the fixing plate engages with the fixing groove opened on the inner side of the guide channel body. The engagement of the fixing plate and the fixing groove helps to improve the stability of the stabilizing plate supporting the cover plate body.

[0019] In summary, the present invention has the following beneficial technical effects:

[0020] (1) In this invention, the cover plate body is assembled by hinges from a movable plate, a connecting plate, a horizontal plate and a support plate, and has telescopic properties. Then, the movable plate is driven by a drive component to slide between two slide rails, thereby causing the cover plate body to retract, which can play the role of opening and closing the cover plate body, which is beneficial to reducing the storage space of the cover plate body.

[0021] (2) In this invention, by setting up the support component, the support plate is driven by the cylinder to move the same side stabilizing plate into the interior of the flow channel body. Then, the same side stabilizing plate is driven to rise by the first telescopic rod and contact the bottom of the cover plate body, which can play the role of supporting and stabilizing the cover plate body, which is beneficial to improving the load-bearing capacity when the two cover plate bodies are closed.

[0022] (3) In this invention, by setting the fixing component, when the stabilizing plate contacts the bottom of the cover plate body, the second telescopic rod drives the fixing plate on the same side to slide to the outside of the mounting groove on the same side, thereby making the fixing plate engage with the fixing groove opened on the inner wall of the guide channel body. The cooperation between the fixing plate and the fixing groove helps to maintain the stability of the stabilizing plate supporting the cover plate body. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below.

[0038] Please see Figure 1-9 A guide channel cover plate includes a platform 1, a guide channel body 2 is provided at the top of the platform 1, slide rails 4 are fixedly installed on the inner walls of both sides of the guide channel body 2, and two cover plate bodies 3 are provided between the two slide rails 4. The cover plate body 3 includes two support plates 304 fixedly installed between the two slide rails 4. A movable plate 301 is provided on the opposite side of the two support plates 304. Two sets of symmetrically distributed horizontal plates 303 are slidably installed between the two slide rails 4. There are at least three horizontal plates 303 in the same set and they are located between the support plates 304 and the movable plates 301 on the same side. A connecting plate 302 is provided between the movable plate 301 on the same side and an adjacent horizontal plate 303, between the support plate 304 and an adjacent horizontal plate 303, and between two adjacent horizontal plates 303 on the same side. Two symmetrically distributed movable wheels are provided at the bottom of the horizontal plates 303 and the movable plates 301. The movable wheels on the same side are located in the slide rails 4 on the same side. A drive assembly is provided between the two movable plates 301 and the slide rails 4.

[0039] The drive assembly includes toothed block plates 5 fixedly installed in two slide rails 4. Two symmetrically distributed mounting seats 13 are fixedly installed at the bottom of each of the two moving plates 301. The cross-section of each mounting seat 13 is "L" shaped. A geared motor 14 is fixedly installed at the top of the horizontal section of each mounting seat 13. The output shaft of the geared motor 14 is connected to a reducer 15. Gears 26 are sleeved on the side wall of the shaft of the reducer 15. Each reducer 15 is fixedly connected to the side opposite to the horizontal section of the mounting seat 13 on the same side. The two gears 26 on the same side mesh with the toothed block plates 5 on the same side. Slide grooves 22 are opened on the inner walls of both sides of the guide channel body 2. Two symmetrically distributed sliders 21 are slidably installed in each of the two slide grooves 22. The two sliders 21 are fixedly connected to the side opposite to the two mounting seats 13 on the same side.

[0040] When in use, the cover plate body 3 is assembled from a movable plate 301, a connecting plate 302, a horizontal plate 303, and a support plate 304 using hinges in the prior art. It is telescopic. The geared motor 14 drives the reducer 15 on the same side to rotate. The reducer 15 drives the gear 26 on the same side to rotate. The gear 26 meshes with the toothed block plate 5 on the same side. The geared motor 14 and the reducer 15 are both fixed to the mounting base 13 on the same side. The mounting base 13 is fixed to the bottom end of the movable plate 301 on the same side. When the geared motor 14 drives the gear 26 on the same side to rotate, the toothed block plate 5 is fixedly connected to the inner side of the slide rail 4 on the same side. The movable plate 301 slides between the two slide rails 4 under the action of the driving force, thereby causing the movable plate 301 to push the horizontal plate 303 and the connecting plate 302 on the same side to contract or extend, which can achieve the function of closing or opening the guide channel body 2.

[0041] A first retraction assembly is provided between two movable plates 301. The first retraction assembly includes two first mounting plates 8 fixedly installed on the top of one of the movable plates 301, and a locking plate 9 rotatably installed between the two first mounting plates 8. Two symmetrically distributed second mounting plates 10 are fixedly installed on the top of the other movable plate 301, and a positioning rod 11 is fixedly installed between the two second mounting plates 10. A handle is fixedly installed on the top of the locking plate 9, and a positioning groove is provided at the bottom of the locking plate 9. Grooves 801 are provided on the side of each of the two first mounting plates 8 near the second mounting plates 10. When the two movable plates 301 move relative to each other, the first mounting plates 8 and the second mounting plates 10 move relative to each other. When contact occurs, the positioning rod 11 installed between the two second mounting plates 10 pushes the clamping plate 9 located between the two first mounting plates 8 to rotate, thereby causing the clamping plate 9 to rotate upward between the two first mounting plates 8. Subsequently, as the positioning rod 11 moves between the two first mounting plates 8, the clamping plate 9 descends under the action of gravity, causing the positioning rod 11 to engage with the positioning groove opened at the bottom of the clamping plate 9, which can fix the two moving plates 301 and help maintain the stability of the two cover plate bodies 3. When it is necessary to retract the two cover plate bodies 3, the operator pulls the clamping plate 9 by the handle, thereby causing the positioning groove opened at the bottom of the clamping plate 9 to disengage from the positioning rod 11, and then the two cover plate bodies 3 can be retracted.

[0042] A second shrinking assembly is provided between the two movable plates 301. The second shrinking assembly includes two first support blocks 7 fixedly installed on the top of one of the movable plates 301, and two second support blocks 12 symmetrically distributed fixedly installed on the top of the other movable plate 301. The tops of the first support blocks 7 and the second support blocks 12 are provided with through holes. A fixing pin 6 is provided between the first support blocks 7 and the second support blocks 12 on the same side. The height of the second support block 12 is lower than the height of the first support block 7. When the two movable plates 301 are attached, the second support block 12 moves to the bottom of the first support block 7 on the same side. Then, the worker places the fixing pin 6 into the through hole opened on the side wall of the first support block 7 and the second support block 12 on the same side, which can further fix the two movable plates 301. When it is necessary to shrink the cover plate body 3, the worker can remove the fixing pin 6.

[0043] The inner walls of both sides of the guide channel body 2 are provided with receiving slots 16. Each receiving slot 16 is provided with a support assembly, which includes a support plate 18 slidably installed in the two receiving slots 16. The cross-section of the two support plates 18 is "L" shaped. Multiple cylinders 17 arranged in a linear array are fixedly installed on the inner walls of opposite sides of the two receiving slots 16. The piston shafts of the cylinders 17 on the same side are fixedly connected to the opposite side of the vertical section of the support plate 18 on the same side. Stabilizing plates 19 are provided above the horizontal sections of the two support plates 18. Multiple rectangular arrays are provided at the top of the horizontal sections of the two support plates 18. The first telescopic rod 20 is distributed, and the top of the first telescopic rod 20 on the same side is fixedly connected to the bottom of the stabilizing plate 19 on the same side. The two stabilizing plates 19 are provided with mounting grooves 25 on both sides. After the two cover plate bodies 3 are closed, the cylinder 17 drives the support plate 18 on the same side to move the stabilizing plate 19 to the outside of the storage groove 16 on the same side. Then, the first telescopic rod 20 drives the stabilizing plate 19 to rise, so that the stabilizing plate 19 contacts the bottom of the cover plate body 3. Through the cooperation of the two stabilizing plates 19, the cover plate body 3 is supported and stabilized, which helps to improve the load-bearing capacity of the cover plate body 3.

[0044] Each mounting slot 25 is equipped with a fixing component, and a fixing plate 23 is slidably installed in each mounting slot 25. Two symmetrically distributed second telescopic rods 24 are fixedly installed on the inner wall of the opposite side of the two mounting slots 25 on the same side. The ends of the two second telescopic rods 24 on the same side are fixedly connected to the opposite side of the fixing plate 23 on the same side. The inner wall of the guide channel body 2 is provided with a fixing groove that matches the fixing plate 23 on the same side. When the stabilizing plate 19 is attached to the bottom of the cover plate body 3, the second telescopic rods 24 drive the fixing plate 23 on the same side to move to the outside of the mounting slot 25 on the same side, so that the fixing plate 23 engages with the fixing groove opened on the inner side of the guide channel body 2. The engagement of the fixing plate 23 and the fixing groove helps to improve the stability of the stabilizing plate 19 supporting the cover plate body 3.

[0045] The implementation principle of this invention is as follows: When the device is in use, the cover plate body 3 is assembled from a movable plate 301, a connecting plate 302, a horizontal plate 303, and a support plate 304 using hinges in the prior art, and has telescopic properties. The movable plate 301 on the same side is driven to slide within the slide rail 4 by a drive assembly. The movable plate 301 pushes the connecting plate 302 and the horizontal plate 303 on the same side to slide, thus retracting the cover plate body 3, facilitating the opening of the guide channel body 2. Furthermore, both the movable plate 301 and the horizontal plate 303 have bottom features... The device has casters to facilitate the sliding of the movable plate 301 and the horizontal plate 303 within the slide rail 4. When it is necessary to close the guide channel body 2, the movable plate 301 is driven to slide between the two slide rails 4 by the drive assembly. The movable plate 301 pulls the horizontal plate 303 and the connecting plate 302 on the same side to move, thereby closing the two movable plates 301 and thus closing the guide channel body 2. A first shrinking assembly and a second shrinking assembly are provided between the two movable plates 301 to fix and shrink the two movable plates 301.

[0046] After the two cover plate bodies 3 are locked, the support assembly moves to the bottom of the two cover plate bodies 3 and makes the support assembly contact the bottom of the cover plate body 3, which plays a role in supporting and stabilizing the cover plate body 3 and helps to improve the load-bearing capacity of the cover plate body 3.

[0047] When the cover plate body 3 moves from the closed state to the open state, the reduction motor 14 may fail and cannot operate normally. In this case, after the cover plate body 3 is opened and the limit lock is tightened, it needs to be connected to the top of the moving plate 301 by a rope in the prior art, and then the cover plate body 3 is pulled by the rope to ensure that the cover plate body 3 can be opened smoothly in the event of failure of the reduction motor 14.
