DETAILED DESCRIPTION

[0020] like Figure 1-Figure 6 As shown, the utility model is a reactor blanking pipe blind plate disassembly device comprising a mobile vehicle 1, to which a hydraulic telescopic rod 2 is fixedly connected, the upper part of the hydraulic telescopic rod 2 extends out of the top surface of the mobile vehicle 1, the front end of the piston rod of the hydraulic telescopic rod 2 extends out of the top surface of the mobile vehicle 1, the front end of the piston rod of the hydraulic telescopic rod 2 is rotatably connected to a support rod 3, one end of the support rod 3 away from the piston rod of the hydraulic telescopic rod 2 is fixedly connected to a support plate 4, and the support plate 4 is supported on the side of the blanking pipe blind plate 11 away from the blanking pipe flange 10.

[0021] The drop pipe 9 of the reactor in the prior art is tilted downward, the drop pipe flange 10 is fixedly connected to the drop pipe 9, and the drop pipe blind plate 11 is connected to the drop pipe flange 10 by multiple fasteners evenly distributed around the circumference. The utility model is supported on the drop pipe blind plate 11 by the support plate 4, thereby avoiding falling or collision when the drop pipe blind plate 11 is disassembled. The hydraulic telescopic rod 2 can be extended and retracted up and down in the height direction, so it can be suitable for drop pipe blind plates 11 of different heights.

[0022] The support plate 4 includes a circular plate 401 and a lug plate 402. Two lug plates 402 are provided. The two lug plates 402 are respectively fixedly connected to the left and right sides of the circular plate 401. The two lug plates 402 are arranged on the same straight line. The outer diameter of the circular plate 401 is smaller than the hole pitch of the fastener connecting holes on the blanking tube blind plate 11. The fasteners of the blanking tube blind plate 11 are all arranged on the outside of the circular plate 401. Screw holes 403 are provided on the two lug plates 402. The screw holes 403 are connected to the support screws 12. The front end of the support screw 12 extends out of the screw hole 403. The front end of the support screw 12 extending out of the screw hole 403 is inserted into the fastener connecting hole of the blanking tube blind plate 11.

[0023] Since the support plate 4 is only supported on the blanking tube blind plate 11 without being fixed, there is still a certain risk of falling, especially when the mobile vehicle 1 moves. Therefore, the utility model uses the support screw 12 to support the blanking tube blind plate 11. When in use, first remove the multiple fasteners on the blanking tube blind plate 11 to only one pair on a straight line, loosen the remaining pair of fasteners but do not completely detach them. At this time, support the support plate 4 on the blanking tube blind plate 11, and make the remaining pair of fasteners located on the outside of the circular plate 401, so that the circular plate 401 will not block the removal of the fasteners, rotate the support screw 12 so that the front end of the support screw 12 is inserted into the fastener connecting hole of the blanking tube blind plate 11, at this time, the support screw 12 cooperates with the support plate 4 to form a support for the blanking tube blind plate 11, and finally remove the remaining pair of fasteners. Due to the support of the support screw 12 on the blanking tube blind plate 11, the blanking tube blind plate 11 will not fall off the support plate 4, and it can remain stable during movement.

[0024] A groove 301 is provided at one end of the support rod 3 away from the support plate 4, and arc grooves 302 are provided on both side walls of the groove 301, and the two arc grooves 302 are symmetrical.

[0025] The utility model can conveniently change the angle of the support plate 4 by connecting the arc groove 302 with the ball head 201, so as to match the blanking tube 9 and the blanking tube blind plate 11 with different inclination angles. After being adjusted into place, it can be positioned by locking the fasteners, and the operation is relatively simple.

[0026] The top of the mobile vehicle 1 is a rectangular frame formed by welding angle steels, a top plate is welded inside the rectangular frame, telescopic legs 6 are fixedly connected to the four corners of the bottom surface of the rectangular frame, and each telescopic leg 6 is fixedly connected to a caster 7 at the bottom away from the rectangular frame; a through hole Ⅰ101 is provided on the top plate of the mobile vehicle 1, a support cylinder 5 is fixedly connected to the upper side of the top plate of the mobile vehicle 1, the bottom of the hydraulic telescopic rod 2 is connected to the support cylinder 5, and the upper part of the hydraulic telescopic rod 2 extends out of the through hole Ⅰ101; the rectangular frame of the mobile vehicle 1 is fixedly connected with side panels all around, and handles 8 are fixedly connected to the two symmetrical side panels.

[0027] The setting of the caster 7 facilitates the movement of the mobile vehicle 1. In actual use, the caster 7 with a brake function can be used to facilitate the positioning of the mobile vehicle 1 after the movement. The telescopic legs 6 can use a telescopic leg with a rotating structure or a telescopic leg with a plug-in locking structure. The telescopic leg 6 is common knowledge in the art and will not be described in detail again. The setting of the handle 8 allows the mobile vehicle 1 to be pulled.

[0028] The support tube 5 is configured to carry the hydraulic telescopic rod 2 .
