Description

Technical Field

[0001] The present invention relates to the field of guide trough cover plates, and more specifically, to a guide trough cover plate. Background Art

[0002] A guide groove is opened on the top of the launch platform of the carrier rocket. The guide groove has the functions of exhausting gas flow, buffering, environmental protection and cooling, preventing gas from backfiring or rushing to ground facilities, and protecting the safety of rockets and ground facilities. Specifically, the guide groove guides the gas flow generated when the rocket is ignited to the outside of the launch platform to prevent high-temperature gas from damaging the launch facilities and the tail of the rocket. There is usually a large amount of water in the guide groove. When the high-temperature flame meets water, white water mist will form. This water mist not only has a cooling effect, but also absorbs part of the sound energy and reduces the impact noise of the gas flow. There is usually a cover in the guide groove to facilitate the staff to stand and repair the rocket.

[0003] Some existing guide trough internal covers are integrally arranged, which may occupy a large space, and the movement and opening and closing are relatively cumbersome, which reduces the efficiency of opening and closing the cover, and may affect the work efficiency of the staff. Therefore, we propose a guide trough cover. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a guide groove cover plate, which adopts the following technical solution:

[0005] The top of the platform is provided with a guide groove body, and the inner walls of both sides of the guide groove body are fixedly installed with slide rails, and two symmetrically distributed cover plate bodies are arranged between the two slide rails, and the cover plate body comprises two support plates fixedly installed between the two slide rails, and the two support plates are provided with a movable plate on opposite sides, and two groups of symmetrically distributed cross plates are slidably installed between the two slide rails, and the same group of cross plates has at least three and are located between the support plates and the movable plates on the same side, and connecting plates are arranged between the movable plate and an adjacent cross plate on the same side, between the support plate and an adjacent cross plate, and between two adjacent cross plates on the same side, and two symmetrically distributed moving wheels are arranged at the bottom ends of the cross plate and the movable plate, and the moving wheels on the same side are located in the slide rails on the same side, and a driving assembly is arranged between the two movable plates and the slide rails, and a first condensation structure and a second condensation structure are arranged between the two movable plates;

[0006] The inner walls on both sides of the guide groove body are provided with receiving grooves, and the two receiving grooves are provided with supporting components.

[0007] By adopting the above technical scheme, when the device is in use, the cover plate body is composed of a movable plate, a connecting plate, a transverse plate and a support plate which are assembled by hinges in the prior art and have retractability. The driving component drives the movable plate on the same side to slide in the slide rail, and the movable plate pushes the connecting plate and the transverse plate on the same side to slide, which can play the role of shrinking the cover plate body, thereby facilitating the opening of the guide trough body. The bottom of the movable plate and the transverse plate are both provided with movable wheels, which are convenient for the movable plate and the transverse plate to slide in the slide rail. When the guide trough body needs to be closed, the movable plate is driven by the driving component to slide between the two slide rails, and the movable plate pulls the transverse plate and the connecting plate on the same side to move, thereby closing the two movable plates, thereby closing the guide trough body. A first condensation component and a second condensation component are provided between the two movable plates, which play the role of fixing and shrinking the two movable plates.

[0008] When the two cover bodies are locked, the support assembly is moved to the bottom of the two cover bodies, and the support assembly is brought into contact with the bottom of the cover bodies, thereby supporting and stabilizing the cover bodies, which is beneficial to improving the bearing capacity of the cover bodies.

[0009] Furthermore, the driving assembly includes a tooth plate fixedly installed in the two slide rails, two symmetrically distributed mounting seats are fixedly installed at the bottom ends of the two movable plates, the cross-sections of the mounting seats are "L"-shaped, and a reduction motor is fixedly installed on the top of the horizontal section of the mounting seat, the output shaft of the reduction motor is connected to a reducer, and the side walls of the reducer shaft are sleeved with gears, and the reducers are fixedly connected to the side opposite to the horizontal section of the mounting seat on the same side, and the two gears on the same side are meshed with the tooth plate on the same side, and the inner walls on both sides of the guide trough body are provided with sliding grooves, and two symmetrically distributed sliders are slidably installed in the two sliding grooves, and the two sliders are respectively fixedly connected to the side opposite to the two mounting seats on the same side.

When the reduction motor drives the gear on the same side to rotate, the tooth block plate is fixedly connected to the inner side of the slide rail on the same side, and 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, thereby playing the role of closing or opening and closing the guide trough body.

[0011] Furthermore, the first condensation component includes two first mounting plates fixedly installed on the top of one of the movable plates, a card plate is rotatably installed between the two first mounting plates, two symmetrically distributed second mounting plates are fixedly installed on the top of the other movable plate, a positioning rod is fixedly installed between the two second mounting plates, a handle is fixedly installed on the top of the card plate, a positioning groove is provided at the bottom end of the card plate, and grooves are provided on the side of the two first mounting plates close to the second mounting plates.

[0012] By adopting the above technical scheme, when the two movable plates move relative to each other, the first mounting plate and the second mounting plate move relative to each other, and when the two movable plates contact, the positioning rods installed between the two second mounting plates push the card plate located between the two first mounting plates to rotate, thereby causing the card plate to rotate upward between the two first mounting plates, and then the positioning rods move between the two first mounting plates, and then the card plate drops under the action of gravity, so that the positioning rods engage with the positioning grooves opened at the bottom of the card plate, which can fix the two movable plates, and is beneficial to maintaining the stability of the fit of the two cover plate bodies. When the two cover plate bodies need to be retracted, the staff pulls the card plate by the handle, thereby causing the positioning grooves opened at the bottom of the card plate to disengage from the positioning rods, and then the two cover plate bodies can be retracted.

[0013] Furthermore, the second condensation assembly includes two first support blocks fixedly mounted on the top of one of the movable plates, and two symmetrically distributed second support blocks fixedly mounted on the top of the other movable plate, through holes are provided on the tops of the first support blocks and the second support blocks, and fixing pins are provided between the first support blocks and the 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 fitted together, the second support block moves to below the first support block on the same side. Then the staff places the fixing pins in the through holes opened on the side walls of the first support block and the second support block on the same side, which can further fix the two movable plates. When the cover body needs to be retracted, the staff can take out the fixing pins.

[0015] Furthermore, the support assembly includes a support plate slidably installed in the two receiving grooves, the cross-sections of the two support plates are both "L"-shaped, and multiple cylinders distributed in a linear array are fixedly installed on the inner walls on the opposite sides of the two receiving grooves, and 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, and a stabilizing plate is provided above the horizontal sections of the two support plates, and multiple first telescopic rods distributed in a rectangular array are provided on the top of the horizontal sections of the two support plates, and the tops of the first telescopic rods on the same side are fixedly connected to the bottom ends of the stabilizing plates on the same side, and installation grooves are opened on both sides of the two stabilizing plates, and fixing components are provided in the installation grooves.

[0016] By adopting the above technical solution, when the two cover bodies are closed, the cylinder drives the support plate on the same side to move the stabilizing plate to the outside of the storage groove on the same side, and then the first telescopic rod drives the stabilizing plate to rise, so that the stabilizing plate contacts the bottom of the cover body. Through the cooperation of the two stabilizing plates, the cover body is supported and stabilized, which is beneficial to improve the bearing capacity of the cover body. A fixing component is provided between the stabilizing plate and the guide groove body, which fixes the stabilizing plate and is beneficial to maintaining the stability of the stabilizing plate during use.

[0017] Furthermore, a fixing plate is slidably installed in the installation grooves, and two symmetrically distributed second telescopic rods are fixedly installed on the inner walls of the two installation grooves 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, and a fixing groove matching the fixing plate on the same side is provided on the inner wall of the guide groove body.

[0018] By adopting the above technical solution, when the stabilizing plate is in contact with the bottom of the cover body, the second telescopic rod is used to drive the fixing plate on the same side to move toward the outside of the mounting groove on the same side, so that the fixing plate is engaged with the fixing groove opened on the inner side of the guide groove body. The engagement of the fixing plate and the fixing groove is helpful to improve the stability of the support of the cover body by the stabilizing plate.

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

[0020] (1) In the present invention, the cover body is composed of a movable plate, a connecting plate, a horizontal plate and a supporting plate assembled by hinges, and has retractability.
