All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1-9, a thrustor for disassembling an integral ballast bed, comprising a thrusting mainboard 1, a left side fixedly connected with an outer cylinder 3 of the thrusting mainboard 1, a push rod 4 installed inside the outer cylinder 3 and on the left side of the thrusting mainboard 1, a movable rod 5 movably inserted inside the outer cylinder 3 and on the left side of the push rod 4, a pressure spring 6 installed between the push rod 4 and the movable rod 5, a rotating cylinder 7 rotatably connected on the left side of the thrusting mainboard 1 and on the outer side of the outer cylinder 3, a sealing plate 8 movably inserted inside the rotating cylinder 7, a balancing weight 9 arranged on the bottom of the sealing plate 8, a sand outlet 10 arranged on the top of the rotating cylinder 7, a through hole 11 corresponding to the sand outlet 10 arranged on the sealing plate 8, a sand box 12 fixedly connected with the top of the rotating cylinder 7, fine sand 13 placed inside the sand box 12, and sand holes 14 corresponding to the sand outlet 10 arranged on.

Wherein, the pushing main plate 1 is abutted against the integral ballast bed main section 201, the movable rod 5 is abutted against the disassembly section 202, and the disassembly section 202 is pushed out through the push rod 4 and the movable rod 5.

Wherein, push up and install the auto-lock drive arrangement who corresponds with urceolus 3 on the mainboard 1 for urceolus 3 can rotate and fix a position.

Wherein the push rod 4 is driven by a hydraulic cylinder.

Wherein, the left side of movable rod 5 extends to the left side of urceolus 3, is provided with the stopper on the movable rod 5 to avoid movable rod 5 to drop from the urceolus 3.

Wherein, shrouding 8 and balancing weight 9 are the arc, and radian and rotary drum 7 phase-match, and the rotary trough that corresponds with shrouding 8 is seted up to rotary drum 7's inside for shrouding 8 can rotate in rotary drum 7's inside, through setting up balancing weight 9, makes shrouding 8 when static under the action of gravity, and through-hole 11 on the shrouding 8 aligns with sand hole 14 on the urceolus 3.

Wherein, the bottom of the sand box 12 is provided with a leak communicated with the sand outlet 10.

The working principle is as follows: when the integral ballast bed is disassembled, the integral ballast bed is cut off and grooved in advance, the integral ballast bed is divided into an integral ballast bed main section 201 and a disassembled section 202 which is cut off, the pushing main plate 1 is placed between the integral ballast bed main section 201 and the disassembled section 202, the pushing main plate 1 is abutted against the integral ballast bed main section 201, the hydraulic cylinder is started, the push rod 4 and the movable rod 5 move outwards and extend out until the movable rod 5 is abutted against the disassembled section 202, the extending amount of the movable rod 5 can be automatically adjusted by arranging the pressure spring 6, after the disassembly, the section of the disassembled section 202 is not flat, and is uneven or has a slope radian, therefore, the extending length of each movable rod 5 is different, the gravity center of the sealing plate 8 is designed by arranging the counter weight 9, when the sealing plate 8 is balanced and static, the through hole 11 is aligned with the sand hole 14 on the sealing plate, and the initial state is as shown in figure 6, the flask 12 is deflected, the sand outlet 10 is offset from the through hole 11, and the sand outlet 10 is blocked by the closing plate 8, so that the fine sand 13 in the flask 12 does not leak out.

After all the movable rods 5 are abutted to the detaching section 202, the rotary drum 7 is driven to rotate, the sealing plate 8 is movably installed inside the rotary drum 7, and the sealing plate 8 is provided with the balancing weight 9 to fall, therefore, the sealing plate 8 cannot rotate along with the rotary drum 7 until the sand outlet 10 is aligned with the through hole 11, fine sand 13 in the sand box 12 flows into the outer drum 3 through the sand outlet 10 and the sand hole 14 on the sand outlet, a gap between the push rod 4 and the movable rods 5 is filled up, then the rotary drum 7 is rotated, the two sand holes 14 are respectively blocked by the sealing plate 8 and the rotary drum 7, therefore, the fine sand 13 in the outer drum 3 cannot be extruded out, at the moment, the movable rods 5, the fine sand 13 and the push rod 4 are integrally closed entities, at the moment, the hydraulic cylinder is started, the detaching section 202 is pushed through the push rod 4 and the movable rods 5, and the detaching section 202 is detached. After the disassembly section 202 is disassembled, the rotating drum 7 is rotated to 180 degrees, so that the sand outlet 10 is aligned with the sand hole 14 below, the fine sand 13 in the outer cylinder 3 flows into the sand box 12 again, finally, the rotating drum 7 is rotated to the initial position, the whole device is reset, and the next round of pushing and disassembling can be carried out.

In the pushing and detaching process of the integral ballast bed, the hydraulic cylinder applies great thrust to the detaching section 202 through the hydraulic rods, if all the hydraulic rods are not aligned with the detaching section 202, the detaching section 202 is easily pushed and broken due to uneven stress, and part of the hydraulic rods are also excessively stressed, so that detaching work is influenced, and the service life of the hydraulic rods is also influenced; by arranging the sand box 12 and the fine sand 13, when pushing is carried out, the fine sand 13 is filled between the push rod 4 and the movable rod 5 to form a compact whole, so that the problem that the push rod 4 and the movable rod 5 are unstable in connection due to deformation of the pressure spring 6 is solved, the tolerance to high-strength pushing force can be improved due to the compact whole, the firmness is enhanced, the possibility that the outer barrel 3, the push rod 4 and the movable rod 5 are broken or broken is reduced, and the use safety is high; the gap between the push rod 4 and the movable rod 5 is filled by arranging the fine sand 13, and the fine sand 13 has fluidity, so that the filling work under the conditions that the surface of the disassembly section 202 is uneven, the extension amount of the movable rod 5 is inconsistent, and the gap between the push rod 4 and the movable rod 5 is different in size can be met, the filling effect is good, the adjustment and the fixation of the movable rod 5 are more accurate, and the applicability is strong; the flow of the fine sand 13 is controlled by arranging the rotary drum 7 and the closing plate 8, so that the operation is simple, the operation of the rotary drum 7 does not need to consume large driving force, and the energy consumption is low; the whole structure is simple, the operation is convenient, and the popularization and the use are convenient.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
