Abstract

The utility model discloses a tapered wedge adjusting device, which is characterized in that two tapered through holes with horizontal axes are arranged on a housing, a lower sliding support is fixedly mounted on the lower surface of each tapered through hole, an upper movable sliding support is arranged on the upper surface of each tapered through hole, each upper sliding support is in vertical sliding connection with the housing through keying fit, a tapered wedge body penetrates through the two tapered through holes, two lower inclined surfaces of the tapered wedge body respectively slidably contact with the two lower sliding supports, two upper inclined surfaces of the tapered wedge body respectively slidably contact with lower surfaces of the two upper sliding supports, a hydraulic cylinder is fixedly connected to a cylinder support, and a piston rod of the hydraulic cylinder is connected with lugs of the tapered wedged body. The tapered wedge adjusting device increases adjustment quantity of taper wedges, and only needs one set of hydraulic cylinder driving device, thereby reducing cost, saving operating space, increasing stability of systems and being economic, safe and reliable.

Description

Wedge adjusting equipment

Technical field

The utility model belongs to technical field of metallurgical equipment, relates to a kind of wedge adjusting equipment.

Background technology

In the operation of rolling of roll, roll wear phenomenon can occur gradually, and then variation has taken place in roll gap, or after roll change, variation has taken place in the absolute altitude of roll line, therefore need take certain measure to adjust, roll gap or roll line absolute altitude are returned within the scope of design load or the permission of roll line absolute altitude.Existing wedge adjusting equipment needs upper and lower wedge to be used on the one hand, and the working face of wedge is smaller; Need two hydraulic cylinders to drive upper and lower wedge respectively simultaneously on the other hand, and the bar electrical path length that makes two hydraulic cylinders stretch out simultaneously wants consistent, make two to go up the sliding support piece on a horizontal plane, by upper and lower wedge move toward one another, to obtain the adjustment on the short transverse, the upper and lower wedge of this Technology Need is used two Driven by Hydraulic Cylinder respectively, and the adjustment amount of wedge is restricted.Continuous development along with science and technology, the rolling requirement of breaker roll also improves gradually, because the wear extent of roll on diametric(al) is increasing, existing wedge adjustment amount can not satisfy industrial accuracy requirement, loaded down with trivial details, the inefficiency of wedge adjustment work have influenced normal production.

Summary of the invention

The purpose of this utility model provides a kind of wedge adjusting equipment, has solved that the adjustment amount of wedge is little in the prior art, adjustment work is loaded down with trivial details, adjust inefficient problem.

The technical solution adopted in the utility model is, a kind of wedge adjusting equipment, on memorial archway, have the conical through-hole of two groups of axis horizontal, the lower surface of each conical through-hole is installed with a lower slider and supports, the upper surface of each conical through-hole is provided with the last sliding support of an activity, sliding support keeps sliding up and down being connected by the key cooperation with memorial archway on each, be installed with a wedge body in these two groups of conical through-holes, two groups of lower inclined planes of wedge body support sliding-contacts with two lower slider respectively, two groups of ramps of wedge body respectively with two lower surface sliding-contacts of going up sliding supports; A fixedly connected hydraulic cylinder on cylinder support, the piston rod of hydraulic cylinder is connected with the wedge lug of wedge body.

Wedge adjusting equipment of the present utility model, its feature also is: described wedge body is that two monocline wedge tandems merging are made, and is provided with two groups of ramps and two groups of lower inclined planes of structure unanimity.

The beneficial effects of the utility model are, make the adjustment amount of wedge be improved, and only need a Driven by Hydraulic Cylinder device, have reduced cost, have saved working space, have improved the stability of system, economic, safety, reliable.

Description of drawings

Fig. 1 is the wedge body construction schematic diagram in the wedge adjusting equipment of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is a wedge adjusting equipment structural representation of the present utility model;

Fig. 4 is the vertical view of Fig. 3.

Among the figure, 1. hydraulic cylinder, 2. memorial archway, 4. wedge body, 5. the wedge lug is 6. gone up sliding support, and 7. lower slider supports, 8. cylinder support.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, Fig. 2, wedge body 4 of the present utility model is two wedges that monocline wedge tandem combination system makes, be provided with two groups of ramps and two groups of lower inclined planes of structure unanimity, the upper and lower inclined-plane of two monocline wedges is symmetry fully, like this if the height that last sliding support 6 needs to adjust is L, only need wedge body 4 L/2 that moves in vertical direction, therefore, the face length of wedge is improved, and then has improved the adjusting range of wedge.

As Fig. 3, Fig. 4, the structure of wedge adjusting equipment of the present utility model is, on memorial archway 2, have the conical through-hole of two groups of axis horizontal, the lower surface of each conical through-hole is installed with a lower slider and supports 7, the upper surface of each conical through-hole is provided with the last sliding support 6 of an activity, sliding support 6 keeps sliding up and down being connected by the key cooperation with memorial archway 2 on each, be installed with a wedge body 4 in these two groups of conical through-holes, two groups of lower inclined planes of wedge body 4 support 7 sliding-contacts with two lower slider respectively, two groups of ramps of wedge body 4 respectively with two lower surface sliding-contacts of going up sliding supports 6; A fixedly connected hydraulic cylinder 1 on cylinder support 8, the piston rod of hydraulic cylinder 1 is connected with the wedge lug 5 of wedge body 4, and wedge body 4 is subjected to the driving of hydraulic cylinder 1.

When wedge adjusting equipment of the present utility model is worked, Driven by Hydraulic Cylinder wedge body 4 is moved to the left, wedge body 4 moves upward along the ramp of lower slider support 7, this moment is by sliding support 6 in the mobile lifting on inclined-plane, feasible upward sliding support 6 is done on memorial archway 2 along keyway and is moved both vertically, and then adjusts the absolute altitude of roll line.

Wedge adjusting equipment of the present utility model is compared with existing wedge adjusting equipment, structurally, this wedge adjusting equipment has a style of one's own, and only need use a Driven by Hydraulic Cylinder wedge, solve well the deficiency that existing wedge adjusting equipment exists, and so that effective work area of wedge becomes big, increased the scope of wedge adjustment amount, also improve the stability of device, reduced cost.
