Detailed Description
The present invention is described in detail below with reference to the following embodiments and accompanying drawings:
a blast furnace stave dismantles frock, refer to fig. 1 to 6, in the figure: the furnace comprises a base body 1, a welding part 101, a connecting part 102, an open part 1021, a limiting part 1022, a power device 2, a limiting block 201, a primary oil cylinder 202, a secondary oil cylinder 203, a cooling wall 3, a furnace shell 4, a cooling wall water pipe 5 and a bolt hole 6.
In this embodiment, base body 1 sets up with power device 2 is supporting, and base body 1 is cyclic annular tube structure, and power device adopts the pneumatic cylinder, and base body 1 wholly is cyclic annular tube structure, and base body 1 suit is on the pneumatic cylinder outer wall, and base body 1 sets up with the pneumatic cylinder coaxial line.
The base body 1 is divided into a welding part 101 and a connecting part 102, and the connecting part 102 is connected with a limiting block 201 of the power device; stopper 201 is the rectangle structure, stopper 201 and hydraulic cylinder body structure, belongs to the customized product.
The connecting portion 102 has an opening portion 1021 and a limiting portion 1022 at an end thereof, and the limiting portion 1022 is disposed near the welding portion and is provided with a limiting block 201.
50 ton and 100 ton gauge. In the process of dismantling the cooling wall, the cooling wall needs to be jacked by about 400mm, and the defect is overcome well by adopting the two-stage double-acting hydraulic cylinder.
The circumferential width of the open part 1021 at the end far from the connecting part 102 is smaller than that at the end near the connecting part 102.
The open part 1021 is in a' type space structure; the position-limiting portion 1022 is a solid structure of a shape of a' which is inverted with respect to the space of the opening portion 1021.
The circumferential width of the open portion 1021 is greater than or equal to the circumferential width of the limiting block 1022, (the circumferential width is the width in the circumferential direction, since the open portion has a difference between the inner and outer diameters, more specifically, the radian must be consistent), the circumferential width of the limiting block 1022 is equal to the circumferential width of the limiting block 201, and the axial length of the limiting block 1022 is equal to the axial length of the limiting block 201 (specifically, the limiting block 1022 and the limiting block 201 must be matched, so that excessive gap allowance does not exist, and the limiting block 201 can be smoothly taken out and clamped).
The hydraulic cylinder and the base body 1 are arranged concentrically, and the welding process is simple to operate, time-saving and labor-saving.
The connecting portion equipartition that this frock adopted sets up to 3, can be according to actual need equipartition 2, 4 or 5 all feasible.
The tool is simple to operate, after the outer connecting pipes and bolts of the cooling wall 3 are removed, the base body 1 and the blast furnace body furnace shell 4 are welded, the position corresponding to the holes 5 or the bolt holes 6 of the cooling wall water pipe is ensured, and the base body 1, the holes 5 and the bolt holes 6 of the cooling wall water pipe are concentrically arranged; the hydraulic cylinder is screwed into the base body 1, so that the limiting block 201 and the base body 1 are rotationally locked.
