[0014] Compared with the prior art, the present invention provides a nuclear power cable tray dismantling device, which has the following features:

[0015] Beneficial effects:

[0016] 1. The nuclear power cable tray dismantling device uses a first cylinder to push a horizontal shaft to slide on a horizontal rail, and a support shaft to drive a collar to rotate on the horizontal shaft, causing an inclined plate to drive a support plate to rotate on a connecting rail. This facilitates the top plate to be flush with the cable tray, pushing the top plate upward to hold the cable tray in place and ensuring stability during cable tray cutting.

[0017] 2. This nuclear power cable tray removal device uses a drive motor to rotate a threaded rod, causing a support rod to slide inside the sliding opening. This, in turn, causes an auxiliary plate to press against the bottom of the cable tray, further ensuring the stability of the cable tray during cutting. A second cylinder drives a clamping plate to hold the cable tray in place. Then, a cutting device is used to cut the cable tray between the auxiliary plate and the top plate. An electric push rod pushes a third connecting rod upward, causing the rotating drum to rotate. This causes the second connecting rod to deflect downward, which in turn causes the first fixing plate to flip downward, allowing the cut cable tray to flip downward for easy removal. A rotating shaft facilitates the rotation of the rotating drum.

[0018] 3. In this nuclear power cable tray removal device, the pressure shaft moves out from the inside of the airbag as the third connecting rod moves. At this time, the sealing gasket moves up with the pressure ring. The connecting ball pulls the second spring down to block the inside of the inner cylinder. The air hole can slow down the air entering the inside of the airbag, thereby slowing down the upward movement speed of the pressure shaft and thus slowing down the downward movement speed of the first fixed plate. When the third connecting rod rotates, the airbag moves out from the inside of the inner cylinder under the action of the air pressure inside the airbag. At this time, the air will be discharged from the inside of the inner cylinder, thus facilitating the air discharge. Attached Figure Description

[0028] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Please see Figure 1 - Figure 8 A nuclear power cable tray dismantling device includes a trolley head 1, with two sets of horizontal rails 2 fixedly connected to the rear end of the trolley head 1, a connecting rail 3 fixedly connected between the two sets of horizontal rails 2, rollers 4 rotatably connected to both ends of the connecting rail 3, a support plate 5 rotatably connected to the upper end of the connecting rail 3, an inclined plate 6 provided at the front end of the support plate 5, a top plate 7 movably connected to the upper end of the inclined plate 6, and an auxiliary component 8 for providing auxiliary support for the cable tray provided at the upper end of the support plate 5.

[0030] In this embodiment, the included angle between the support plate 5 and the inclined plate 6 is between 100 degrees and 145 degrees. Two sets of fixing rings 9 are fixedly connected to the outer side of the connecting rail 3. A rotating ring 10 is rotatably connected to the outer side of the fixing ring 9. A support column 11 is fixedly connected to the outer side of the rotating ring 10. The support column 11 is fixedly connected to the support plate 5.

[0031] A fixing block 16 is fixedly connected to the upper end of the connecting rail 3. A first cylinder 17 is fixedly connected to the front end of the fixing block 16. A slip ring 12 is fixedly connected to the outer side of the horizontal rail 2. A horizontal shaft 13 is fixedly connected between the two sets of slip rings 12. A collar 14 is rotatably connected to the outer side of the horizontal shaft 13. A support shaft 15 is fixedly connected to the outer side of the collar 14. The support shaft 15 is rotatably connected to the inclined plate 6.

[0032] Specifically, the first cylinder 17 can push the horizontal shaft 13 to slide on the horizontal rail 2, and the support shaft 15 can drive the collar 14 to rotate on the horizontal shaft 13, so that the inclined plate 6 drives the support plate 5 to rotate on the connecting rail 3. This makes it convenient for the top plate 7 to be parallel to the cable tray, and pushing the top plate 7 to move upward can hold the cable tray in place, ensuring stability when the cable tray is cut.

[0033] In this embodiment, the auxiliary component 8 includes an auxiliary plate 81 that is slidably connected to the support plate 5. The lower end of the auxiliary plate 81 is rotatably connected to a first connecting rod 82. The upper end of the first connecting rod 82 is fixedly connected to a first fixing plate 83. The lower end of the first fixing plate 83 is fixedly connected to two sets of second cylinders 810. The output end of the second cylinder 810 is fixedly connected to a clamping plate 84.

[0034] Specifically, the first fixing plate 83 can support the cut cable tray, making it easier for the cut cable tray to move down.

[0035] In this embodiment, two sets of mounting blocks 86 are fixedly connected to the lower end of the support plate 5, and a threaded rod 87 is rotatably connected between the two sets of mounting blocks 86. A drive motor 88 is fixedly connected to the lower end of the support plate 5, and the output end of the drive motor 88 is fixedly connected to the threaded rod 87. Two sets of support rods 89 are threadedly connected to the outer side of the threaded rod 87. A sliding opening 85 is opened at the upper end of the support plate 5, and the support rods 89 are slidably connected to the inner side of the sliding opening 85. The support rods 89 are fixedly connected to the auxiliary plate 81.

[0036] Specifically, the drive motor 88 drives the threaded rod 87 to rotate, causing the support rod 89 to slide inside the slide 85, which in turn drives the auxiliary plate 81 to press against the bottom of the bridge frame, further ensuring the stability of the bridge frame during cutting. The second cylinder 810 can drive the clamping plate 84 to clamp the bridge frame to ensure the stability of the bridge frame during cutting.

[0037] In this embodiment, a rotating shaft 819 is fixedly connected to both sides of the auxiliary plate 81. A spring piece 820 is rotatably connected to the outer side of the rotating shaft 819. A second connecting rod 812 is fixedly connected to the rear end of the outer side of the spring piece 820. The second connecting rod 812 is fixedly connected to the first fixed plate 83. A third connecting rod 813 is fixedly connected to the front end of the spring piece 820. A connecting plate 815 is fixedly connected to the lower end of the auxiliary plate 81. A second fixed plate 816 is fixedly connected to the lower end of the connecting plate 815. An electric push rod 817 is fixedly connected to the upper end of the second fixed plate 816. A rotating groove 814 is opened at the rear end of the third connecting rod 813. The output end of the electric push rod 817 is rotatably connected to the inner side of the rotating groove 814. A buffer member 818 is provided at the front end of the second fixed plate 816 to assist the rotation of the first fixed plate 83.

[0038] Specifically, the electric push rod 817 pushes the third connecting rod 813 upward, causing the rotating drum 811 to rotate, which in turn causes the second connecting rod 812 to deflect downward, thereby causing the first fixing plate 83 to flip downward, so that the cut cable tray can be flipped downward, making it easier to remove the cut cable tray.

[0039] In this embodiment, a spring piece 820 is provided on the outer side of the rotating shaft 819. The spring piece 820 is located on the inner side of the rotating cylinder 811. One end of the spring piece 820 is fixedly connected to the rotating cylinder 811, and the other end of the spring piece 820 is fixedly connected to the rotating shaft 819.

[0040] Specifically, the rotating shaft 819 facilitates the rotation of the drum 811.

[0041] In this embodiment, the buffer 818 includes an airbag 8181 fixedly connected to the second fixed plate 816. A pressure shaft 8182 is slidably connected to the inner side of the airbag 8181. A connecting shaft 8183 is rotatably connected to the inner side of the rotating groove 814. The connecting shaft 8183 is fixedly connected to the pressure shaft 8182. A pressure ring 8184 is fixedly connected to the lower end of the pressure shaft 8182. A sealing gasket 8185 is provided at the upper end of the pressure ring 8184.

[0042] In this embodiment, an inner cylinder 8187 is fixedly connected to the inner side of the airbag 8181. A connecting ring 8188 is fixedly connected to the upper end of the inner cylinder 8187. A second spring 8189 is fixedly connected to the lower end of the connecting ring 8188. The second spring 8189 is located inside the inner cylinder 8187. A connecting ball 8191 is fixedly connected to the lower end of the second spring 8189. The second spring 8189 fits into the inner cylinder 8187. An air hole 8192 is provided on the outer side of the connecting ball 8191.

[0043] Specifically, the pressure shaft 8182 will move out from the inside of the airbag 8181 as the third connecting rod 813 moves. At this time, the sealing gasket 8185 will move up with the pressure ring 8184. The connecting ball 8191 will pull the second spring 8189 down to block the inside of the inner cylinder 8187. The air hole 8192 can slow down the air entering the inside of the airbag 8181, thereby slowing down the upward movement speed of the pressure shaft 8182, and thus slowing down the downward movement speed of the first fixed plate 83.

[0044] In this embodiment, a first spring 8186 is fixedly connected to the inner side of the airbag 8181, the upper end of the first spring 8186 is fixedly connected to the pressure ring 8184, and the inner cylinder 8187 is located inside the first spring 8186.

[0045] Specifically, the first spring 8186 can pull the pressure ring 8184 to prevent the pressure ring 8184 from moving upward quickly and ensure the safety of the pressure shaft 8182.

[0046] It should be noted that during use, the first cylinder 17 is activated to push the horizontal shaft 13 to slide on the horizontal rail 2, thereby pushing the support shaft 15 forward. At this time, the support shaft 15 will drive the collar 14 to rotate on the horizontal shaft 13, while simultaneously lifting the inclined plate 6 and driving the support plate 5 to rotate on the connecting rail 3, so that the support column 11 drives the rotating ring 10 to rotate on the fixed ring 9. When the top plate 7 is parallel to the cable tray, pushing the top plate 7 upward can hold the cable tray in place. Then, the drive motor 88 is activated to drive the threaded rod 87 to rotate, causing the support rod 89 to slide inside the sliding mouth 85, thereby driving the auxiliary plate 81 to press against the bottom of the cable tray. Then, the second cylinder 810 is activated to drive the clamping plate 84 to clamp the cable tray. Then, the cutting equipment is used to cut the cable tray between the auxiliary plate 81 and the top plate 7. After the cutting is completed, the drive motor 88 is activated again to move the auxiliary plate 81 down to the appropriate position. Then, the electric push rod 817 is activated to push the third connecting rod 8. 13 moves upward, causing the rotating drum 811 to rotate, causing the second connecting rod 812 to deflect downward, which in turn causes the first fixing plate 83 to flip downward, making the cut cable tray flip downward, facilitating the removal of the cut cable tray. As the rotating drum 811 rotates, the rotating shaft 819 will retract accordingly, and at the same time, the pressure shaft 8182 will move out from the inside of the air bag 8181 along with the movement of the third connecting rod 813. At this time, the sealing gasket 8185 will move upward along with the pressure ring 8184. At this time, the connecting ball 8191 will block the inside of the inner cylinder 8187 under the action of the second spring 8189. Air can only enter the inside of the air bag 8181 from the inside of the air hole 8192, thereby slowing down the upward movement speed of the pressure shaft 8182. When the third connecting rod 813 rotates back, the air bag 8181 will move out from the inside of the inner cylinder 8187 under the action of the air pressure inside the air bag 8181. At this time, the air will be discharged from the inside of the inner cylinder 8187, thus facilitating the discharge of air.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
