Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model discloses a buffering apart from adjusting device's concrete structure on elevator to heavy frame is shown as figure 1 to 5, including the elevator to heavy frame, the elevator includes the frame that encloses by entablature 1, underbeam 2 and two stands 3 to heavy frame, has piled up the polylith from top to bottom in the frame and has been to pouring weight 4. The buffer distance adjusting device on the elevator counterweight frame further comprises a buffer 5 arranged on the elevator counterweight frame and a buffer base 6 arranged on the ground of a pit. When the lower end of the elevator counterweight frame moves to the bottom, the buffer 5 contacts the buffer base 6 first, and the falling impulse of the elevator counterweight frame can be buffered.
The lower beam 2 is of a box-type structure and comprises a front side plate, a rear side plate, an upper side plate and end plates at two ends. The bumper 5 includes a fixed striking plate 51 and a floating striking plate 52, wherein the floating striking plate 52 is mounted below the fixed striking plate 51 by an adjustment bolt 53. Specifically, a bolt through hole is formed in the fixed striking plate 51, a spot welding nut 54 adapted to the adjusting bolt 53 is welded and fixed to the upper end surface of the fixed striking plate 51, and the spot welding screw 54 is located at the orifice edge of the bolt through hole. After the first adjusting nut 55 is threaded on the adjusting bolt 53, the adjusting bolt passes through the bolt through hole on the floating collision plate 52 from bottom to top, and then the second adjusting nut 56 is threaded on the adjusting bolt 53, and the floating collision plate 52 is clamped and fixed at the middle part of the adjusting bolt 53 through the first adjusting nut 55 and the second adjusting nut 56. Finally, the floating striking plate 51 is mounted below the fixed striking plate 51 through the adjusting bolt 53 by fixing the adjusting bolt 53 to the spot welding nut 54.
The floating striking plate 52 comprises a striking surface for striking the bumper base 6, and when the height of the floating striking plate 52 needs to be adjusted to compensate for the elongation of the wire rope, the distance between the floating striking plate 52 and the fixed striking plate 51 can be adjusted by only rotating the positions of the first adjusting nut 55 and the second adjusting nut 56 relative to the adjusting bolt 53.
In this embodiment, the fixed striker plate 51 is fixed to the lower beam 2 by welding. In order to increase the strength of the fixed striking plate 51, the fixed striking plate 51 is of a groove structure with an upward opening, and the structural form can also increase the welding area of the fixed striking plate 51 and the lower beam 2, so that the fixed striking plate and the lower beam are firmly connected. In order to further increase the connection firmness degree of the fixed striking plate 51 and the lower beam 2, a connecting plate 7 for drawing the fixed striking plate 51 from the upper part is welded and fixed on the upper side plate of the lower beam 2, the cross section of the connecting plate 7 is in a T shape, the connecting plate is welded and fixed on the upper side plate through a transverse plate, and the lower end of the vertical plate of the connecting plate is fixed in the middle of the fixed striking plate 51. In other embodiments, the cross-sectional shape of the connecting plate can also be rectangular or other shapes; in the case of a firmly welded fastening striker plate 51, the connecting plate 7 can also be omitted.
In the present embodiment, the floating collision plate 52 has a groove structure with a downward opening, and the floating collision plate 52 has a relatively high strength.
In other embodiments, the opening directions of the fixed striking plate 51 and the floating striking plate 52 can be reversed; the fixed striker 51 and the floating striker 52 may also be plate-like structures or other structures, rather than channel-like structures.
In other embodiments, the lower beam 2 may not be a box structure surrounded by a plurality of plates, but may be a solid beam structure, and only a sinking groove with a lower opening for installing the buffer 5 is formed at the lower end of the solid beam structure; the buffer also can not be installed in the cavity of underbeam 2, but install the outside at underbeam 2, but the elevator is to the stress of counter weight frame edge when buffer 5 and buffer base 6 striking under this condition, easily appears rocking.
Finally, the description is as follows: the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
