Example 1

Referring to fig. 1, fig. 1 is a schematic structural diagram of a simple device for disassembling a hole of an assembling machine. A simple device 100 for disassembling a tunnel of an assembling machine comprises a shield machine Mi-shaped beam 110, the assembling machine 130 and a transport vehicle 150. The assembling machine comprises a walking beam 131, and the assembling machine 130 is in bolted connection with the shield machine Mi-shaped beam 110 through the walking beam 131. A support assembly 170 is also provided between the erector 130 and the transporter 150. The supporting assembly 170 comprises a plurality of mouth-shaped supporting frames 171 and a plurality of lifting assemblies 190, the supporting frames 171 are connected end to end, a plurality of fixing holes 177 are further formed in the two ends of the supporting frames 171, and the fixing holes 177 are used for installing high-strength bolts to fix the two adjacent supporting frames 171. The supporting frame 171 is connected with the walking beam 131 through the lifting assembly 190, and one end of the supporting frame 171, which is far away from the lifting assembly 190, is connected with the transport vehicle 150. The height between the erector 130 and the transport vehicle 150 cannot be determined, when a user selects the simple device 100 for disassembling the erector in the erector hole to install, the support frame 171 with the corresponding height needs to be selected according to the height between the erector 130 and the transport vehicle 150, and then fine adjustment is carried out by using the lifting assembly 190, so that the effect that the gap between the upper plane of the transport vehicle 150 and the lower plane of the walking beam 131 and the support frame 171 is zero is achieved. Then, the disassembly and assembly machine 130 and the transportation vehicle 150 are welded to the support frame 171, and the fixation is completed. And finally, disassembling the connecting bolts between the walking beams 131 and the shield machine cross beams 110, and pulling the assembling machine 130 out of the tunnel.

Referring to fig. 2, fig. 2 is a schematic structural diagram of the supporting frame and the lifting assembly. The plurality of support frames 171 are each provided with a first fixing rod 173 and a second fixing rod 175. The first fixing bar 173 and the second fixing bar 175 are cross-welded, and both the first fixing bar 173 and the second fixing bar 175 are welded to opposite corners of the supporting bracket 171. The weight of the erector 130 is great, and when the support frame 171 supported the erector, in order to avoid the support frame 171 to damage because of the weight of the erector 130 is too big, set up first dead lever 173 and second dead lever 175 along the diagonal welding of support frame 171, can effectively fix the support frame 171, increase the bearing capacity of support frame 171 and avoid the support frame 171 to warp or even damage, the material of first dead lever 173 and second dead lever 175 can be I-shaped steel.

Referring to fig. 3, fig. 3 is an enlarged schematic view of the lifting assembly I. The lifting assembly 190 includes a lifting column 191 and a lifting base 193. The lifting column 191 is in threaded connection with the lifting base 193, and the lifting base 193 is welded with the support frame 171. When the simple device 100 for disassembling the machine in the hole of the assembling machine is used for disassembling the assembling machine, the height of the lower plane of the walking beam 131 and the height of the upper plane of the transport vehicle 150 need to be completely consistent with the height of the supporting component 170, but the height of the lower plane of the walking beam 131 and the height of the upper plane of the transport vehicle 150 are not fixed in actual operation, so the height of the supporting component 170 is also divided into a plurality of specifications, when the supporting component 170 is installed, the height of the lower plane of the walking beam 131 and the height of the upper plane of the transport vehicle 150 need to be measured, the supporting component 170 with the most similar height and smaller than the height of the lower plane of the walking beam 131 and the height of the upper plane of the transport vehicle 150 is selected, then the lifting component 190 is used for adjustment, so that the heights of the two are completely consistent (namely, the gap between the upper plane of the transport vehicle 150 (not shown in the figure) and the lower plane of the walking, by changing the length of the lifting column 191 on the lifting base 193, the clearance between the upper plane (not shown) of the transport vehicle 150 and the lower plane (not shown) of the walking beam 131 and the supporting assembly 190 can be zero.

In addition, an opening 195 is radially formed at one end of the lifting column 191 far away from the lifting base 193, and the opening 195 is used for rotating the lifting column 191. The end of the lifting column 191 far away from the lifting base 193 is provided with a bolt head 197, and the bolt head 197 is used for rotating the lifting column 191. In order to make the operation of the user more convenient and labor-saving when rotating the lifting column 191, the lifting column 191 is provided with an opening 195 and a bolt head 197. When the user rotates the lifting column 191, two ways can be taken: 1. a rod-shaped metal object (steel rod) matched with the opening 195 is selected and inserted into the opening 195, and then the steel rod is horizontally rotated anticlockwise, so that the length of the lifting column 191 in the lifting base 193 can be shortened, and the height of the supporting component 170 is increased; the height of the support assembly 170 may be lowered by rotating the steel bar horizontally clockwise. 2. The user may also choose to rotate the lifting column 191 using a wrench compatible with the bolt head 197, in the same manner as using a steel rod to rotate the lifting column 191.

The supporting frame 171 is at least welded with two lifting assemblies 190, and the plurality of lifting assemblies 190 are arranged on the supporting frame 171 at intervals. In order to ensure that the assembling machine 130 is stably placed on the supporting assembly 170, the lifting assemblies 190 should be uniformly distributed on the supporting frame 171, when only two lifting assemblies 190 are provided, the two lifting assemblies 190 preferably need to be arranged at two ends of the top of the supporting frame 171, so that the assembling machine 130 can be more balanced on the supporting assembly 170, and the supporting frame 171 is not easily deformed. In addition, in order to make the supporting frame 171 have better bearing capacity, more stable and less prone to deformation, the supporting frame 171 is made of an i-shaped steel.

The working principle of the simple device 100 for disassembling the machine in the hole of the assembling machine is as follows:

when the user uses the simple device 100 for disassembling the hole in the assembling machine to disassemble the assembling machine, the track needs to be extended to the front end of the assembling machine, and the transport vehicle 150 is parked below the assembling machine 130. Then, the vertical distance between the upper plane of the transporter 150 and the lower plane 131 of the erector walking beam is determined, and then the supporting component 170 which is adaptive to the vertical distance between the upper plane of the transporter 150 and the lower plane of the erector walking beam 131 is selected. The support frames 171 are respectively placed below the walking beams 131 of the erector and fixed by high-strength bolts through fixing holes, and then the lifting columns 191 are rotated to ensure that the lower ends of the support frames 171 are vertically contacted with the upper plane of the transport vehicle 150, the top ends of the lifting columns 191 are vertically contacted with the lower plane of the walking beams 131, and the gaps between the upper plane of the transport vehicle 150, the lower plane of the walking beams 131 and the support assemblies 190 are zero. Then, the lower end of the support frame 171 is welded to the upper plane of the transport vehicle 150, and the top end of the lifting column 191 is welded to the lower plane of the traveling beam 131. After the welding is ensured to be firm, the connecting bolts of the walking beam 131 and the shield machine cross beam 110 are finally disassembled, the transport vehicle 150 pulls the assembling machine 130 out of the tunnel, and therefore the work of disassembling the assembling machine 130 in the tunnel is completed.
