It should be noted that, the difficulty of adding reation kettle is mainly because reation kettle self volume is great, is inconvenient for the transport, and the pipeline who is connected with reation kettle is more for original reation kettle is inconvenient for remove, in addition, in order to save the expense, prevent that workshop inner tube from being disordered, the reation kettle that newly set up can not be too far away from old equipment, and builds the workstation that supports reation kettle and need weld, in order to satisfy above-mentioned requirement, often need abandon old workstation, need consume a large amount of manpowers, and the establishment of new workstation is also comparatively difficult. In the above supporting platform 300, by providing the carrying plate 310, the plurality of locking assemblies 320 and the plurality of foot seat assemblies 330, the supporting portion 311 on the carrying plate 310 is used for supporting the reaction kettle, the trapezoidal boss 331 on the foot seat main body 332 is clamped in the dovetail groove 312a of the carrying plate 310, the first end of the deflector rod 323 on the locking assembly 320 extends into the dovetail groove 312a to prevent the trapezoidal boss 331 from sliding out of the dovetail groove 312a, thereby fixing the foot seat main body 332 on the carrying plate 310, in addition, the flip cover 333 can be turned around the foot seat main body 332, when the flip cover 333 is turned over, the supporting rod 334 hinged on the flip cover 333 is pulled, so that the roller 337 on the first end of the supporting rod 334 slides in the sliding groove on the foot seat main body 332, when the roller 337 moves to the guiding inclined plane of the anti-falling slider 335, the outer side wall of the roller 337 can apply pressure to the guiding inclined plane, because the guiding inclined plane has an included angle with the moving direction of the roller 337, when the force component is greater than the elastic force applied by the spring 336 to the anti-falling slider 335, the anti-falling slider 335 is pressed to move toward the foot seat body 332, so that the roller 337 can continue to slide along the sliding groove and move to the other end of the anti-falling slider 335, and then the anti-falling slider 335 returns to the initial state under the elastic force of the spring 336, so that the flip 333 is turned to the horizontal position, after the external force is stopped, the flip 333 stops turning, under the action of gravity, there is a tendency of inversion, that is, the roller 337 on the support rod 334 has a driving force to slide toward the initial position, and at this time, the roller 337 is positioned on one side surface of the anti-falling slider 335 without a guiding slope, the pressure applied by the roller 337 to the anti-falling slider 335 can not drive the anti-falling slider 335 to move toward the foot seat body 332 against the elastic force of the spring 336, that is, the anti-falling slider 335 prevents the roller 337 from moving toward the initial position, the anti-falling sliding block 335 keeps a state of abutting against the roller 337, so that the flip 333 keeps a flip state and cannot be turned over, and at the moment, the supporting rod 334, the flip 333 and the foot base main body 332 enclose a triangular structure, so that the supporting rod 334 supports the flip 333, and the structure is firmer; if the flip 333 needs to be reversed and restored to the original state, only the anti-falling slider 335 needs to be pressed, so that the anti-falling slider 335 overcomes the elastic force of the spring 336 and moves towards the direction leaning against the foot seat assembly 330, and thus, the roller 337 arranged on the support rod 334 loses the blocking and can continue to slide along the sliding groove on the foot seat main body 332, that is, the flip 333 can be reversed and restored to the original position; further, the length, width and thickness of the clamping boss 333a arranged on the flip cover 333 are the same as those of the trapezoid boss 331, the clamping boss 333a can slide into the dovetail groove 312a of the clamping part 312 on the other carrying plate 310, and the deflector 323 arranged in the locking assembly 320 on the other carrying plate 310 prevents the clamping boss 333a from leaving the dovetail groove 312a, so as to realize the butt joint function; the elastic member 325 in the locking assembly 320 applies an elastic force to the supporting ring 324, so as to drive the supporting ring 324 to maintain an abutting state with the supporting portion 311 of the carrier plate 310, that is, drive the first end of the driving lever 323 in the locking assembly 320 to be maintained inside the dovetail groove 312a, so that the first end of the driving lever 323 and the inner side wall of the dovetail groove 312a enclose a closed cavity, the closed cavity prevents the trapezoid boss 331 (or the clamping boss 333 a) from leaving the dovetail groove 312a, and when the disassembly operation is required, the handle 322 on the driving lever 323 is pulled, so that the driving lever 323 drives the supporting ring 324 to overcome the elastic force of the elastic member 325, so that the driving lever 323 moves away from the supporting portion 311, and further the first end of the driving lever 323 leaves the dovetail groove 312a, so that the trapezoid boss 331 (or the clamping boss 333 a) can leave the dovetail groove 312a.
Thus, when a reaction kettle needs to be added in a workshop, a new material of the supporting platform 300 is prepared first; according to the above operation, the new foot rest assembly 330 is mounted on the clamping portion 312 of the new support platform, the new foot rest assembly 330 is locked by the locking assembly 320, then the flip cover 333 of the foot rest assembly 330 on the original support platform is turned over, so that the flip cover 333 is in a horizontal state, the dovetail groove 312a of the clamping portion 312 of the new support platform is aligned with the clamping boss 333a of the flip cover 333, the new support platform is pushed, so that the new support platform slides into the dovetail groove 312a of the clamping portion 312 of the new support platform along the clamping boss 333a until the clamping boss 333a abuts against the first end of the deflector 323 on the new support platform, the handle 322 on the locking assembly 320 of the new support platform is pulled, so that the first end of the deflector 323 on the new support platform leaves the inside of the dovetail groove 312a, then the new support platform is pushed until the clamping boss 333a is mounted in place, the deflector 323 on the new supporting platform restores the initial state under the action of the elastic force of the elastic piece 325, the clamping boss 333a of the flip 333 on the original supporting platform is locked in the dovetail groove 312a on the clamping part 312 of the new supporting platform, and the splicing operation of the supporting platform is completed, so that the building of the supporting platform can be completed under the condition of no welding, screwing and other operations, the time and difficulty of adding the reaction kettle are greatly reduced, the original supporting platform is not required to be abandoned due to the splicing on the basis of the original supporting platform, the cost of adding the reaction kettle can be saved, the space between the reaction kettles is smaller, the material conveying pipelines can be conveniently built by maintenance personnel by adopting the splicing mode, meanwhile, the equipment can be conveniently maintained or rebuilt at the later stage, the pipelines in the workshop are more orderly, is beneficial to reasonably planning the internal equipment of the workshop.
