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.

[0009] By adopting the above technical scheme, the reduction motor drives the reducer of the same group to rotate, and the reducer drives the winding roller and the baffle plate on the same side to rotate synchronously, so as to play the role of winding the second steel cable, and the second steel cable pulls the mounting block on the same side, and the mounting block squeezes the spring on the same side to contract, and the two second steel cables pull the moving plate on the same side to slide between the two slide rails, and the moving plate pushes the connecting plate and the support plate on the same side to move, so as to play the role of contracting the cover plate body, and when it is necessary to close the guide groove body, the reduction motor drives the winding roller to rotate in the reverse direction, so as to play the role of unwinding the second steel cable, and then the mounting block moves away from the mounting seat under the elastic force of the spring on the same side, so as to unfold the two cover plate bodies, so as to play the role of closing the guide groove body.

[0010] Furthermore, two symmetrically distributed installation frames are fixedly installed on both sides of the platform, and two symmetrically distributed support wheels are rotatably installed in the installation frames. One end of the second steel cable close to the mounting seat on the same side is located between the two support wheels on the same side and slides.

[0011] By adopting the above technical solution, the second steel cable slides between the two supporting wheels on the same side. The supporting wheels can support the second steel cable and help reduce the friction when the second steel cable slides, thereby protecting the second steel cable.

[0012] Furthermore, the first locking assembly includes two first mounting plates fixedly mounted on the top of one of the movable plates, a card plate is rotatably mounted between the two first mounting plates, two symmetrically distributed second mounting plates are fixedly mounted on the top of the other movable plate, a fixing rod is fixedly mounted between the two second mounting plates, grooves are provided on one side of the two first mounting plates close to the second mounting plates, a handle is fixedly mounted on the top of the card plate, and a fixing groove is provided on the bottom of the card plate.

A fixing groove is provided at the bottom of the card plate, and after the fixing rod exceeds the fixing groove, the card plate drops under the action of gravity, thereby engaging the fixing rod and the fixing groove, which can play the role of preliminarily fixing the two movable plates.

[0014] Furthermore, the second locking assembly includes two first support blocks fixedly installed on the top of one of the movable plates, and a second support block fixedly installed on the top of the other movable plate, the cross-sections of the first support block and the second support block are both inverted "L" shapes, the horizontal section of the second support block is lower than the horizontal section of the first support block, the horizontal sections of the first support block and the second support block are both provided with through holes, and a positioning pin is provided between the first support block and the second support block on the same side.

[0015] By adopting the above technical solution, when the two movable plates are docked, the horizontal section of the second support block moves to below the horizontal section of the first support block on the same side, so that the second support block and the first support block on the same side are fitted together, and then the positioning pin passes through the through holes opened at the top of the first support block and the second support block on the same side, which can fix the first support block and the second support block, and further fix the two cover plate bodies.

Subsequently, the two load-bearing plates are driven to rise synchronously through two sets of telescopic rods and contact with the bottom of the cover plate body, which can play the role of supporting the load-bearing cover plate body, which is beneficial to improve the load-bearing capacity of the cover plate body, and thus facilitates the subsequent staff to stand stably.

[0018] Furthermore, two symmetrically distributed plug rods are fixedly installed on opposite sides of the two supporting plates, slots matching the plug rods are opened on opposite sides of the two supporting plates, and the two groups of plug rods are staggered, sliders are fixedly installed on both sides of the two supporting plates, and sliding grooves matching the sliders on the same side are opened on the inner walls of the two storage grooves.

[0020] Furthermore, two symmetrically distributed hanging rings are fixedly installed on the top of the two movable plates, and a first steel cable is provided on the hanging ring. The first steel cable slides through the platform at one end away from the hanging ring on the same side, and two symmetrically distributed connecting rings are fixedly installed on both sides of the platform.

[0021] By adopting the above technical solution, a first steel cable is provided at the top of each of the two movable plates. When the reduction motor fails, the staff can pull the movable plate on the same side to slide between the slide rails through the first steel cable, thereby opening the guide trough body. Then the staff fixes the first steel cable to the connecting ring on the same side to fix the cover plate body.
