Abstract
The utility model discloses a maintenance tool for mining machinery, and in particular relates to a lift type shaft pulling device. The device comprises a base and four support columns. The device is characterized in that the support columns penetrate through the through holes in the four corners of a square support plate, two jacks which are arrayed on the support plate in parallel, and a lateral pin penetrates through hinge holes in the top ends of piston rods of the two jacks; and two lifting frames are arranged between the support plate and the base, and a first cross rod and a second cross rod are connected between the two lifting frames and connected with each other through a third jack. The device is simple to operate, safe, reliable, time-saving and labor-saving, hinged shafts can be easily pulled out no matter how serious the hinged holes in hydraulic supports are blocked, and the hydraulic supports cannot be damaged.
Description
Technical field
The utility model relates to a kind of maintenance tool of mining machinery, specifically a kind of lift Shaft drawer.
Background technology
The mine underground hydraulic support frame is to assemble into an integral body by back timber, guard beam, connecting rod, base by a plurality of jointed shafts, need when disassembling maintenance jointed shaft is pulled up, but hydraulic support is bulky, part jointed shaft present position is higher, disassemble the workman touch on the ground less than, and the jointed shaft size on the hydraulic support is big, weight is big, in the hinge hole after in addition using foreign material, iron rust etc. is arranged, pull-out resistance is big, relies on manpower to be difficult to pull up jointed shaft merely.
Prior art generally is at cylinder of the top of jack welding, after piston rod stretches out in cylinder fully, with overhead traveling crane jack is hung and to deliver to the jointed shaft position, cylinder abuts against the jointed shaft outside, and the strength when utilizing the piston rod retraction is extracted jointed shaft, and mainly there is following problem in it: the one,, owing to have only a jack, strength is limited, when too much or seriously stopping up as if chance hinge hole iron rust, is difficult to extract jointed shaft; The 2nd,, after jack takes out jointed shaft, there is not attachment position aloft, carrying jointed shaft and aloft rocking back and forth, there is potential safety hazard.
The utility model content
The utility model provides a kind of lift Shaft drawer for addressing the above problem.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of lift Shaft drawer comprises base and four pillars, and it is characterized in that: pillar passes the through hole of four jiaos of square supporting plates, and supporting plate can be slided up and down along pillar; Two jack that are arranged in parallel are arranged on the supporting plate, and lateral pin is applied in the hinge hole on piston rod top of two jack; Two cranes are arranged between aforementioned supporting plate and the base, be connected with first cross bar, second cross bar between two cranes, first cross bar, second cross bar connect by the 3rd jack.
There is the universal wheel of strap brake aforementioned base below, is convenient to the utility model and moves.
Two jack ends on the aforementioned supporting plate also have hinge hole, and the hinge hole that pin passes the jack end is connected to two jack on the left hinged-support and right hinged-support of supporting plate, and the middle part of jack is fixed on the supporting plate by the U-shaped snap ring.
All there are hinged through hole and pulley in the two ends of aforementioned crane, and bearing pin passes the hinged through hole at crane two ends, two cranes are connected on the lower hinge support of the upper hinge support of supporting plate bottom and base.
Aforementioned the 3rd jack is identical with two jack structures on the supporting plate, and the hinge hole at the 3rd jack two ends is socketed in respectively on first cross bar, second cross bar.
Adopt technique scheme, when the jointed shaft position on the hydraulic support was higher, the piston rod that can adjust the 3rd jack stretched out, and made first cross bar, second cross bar drive crane and rose, and the jack height on the supporting plate was adjusted to the horizontal level of jointed shaft.
Not holding in the horizontal direction near the jointed shaft on the hydraulic support that need disassemble of two jack on the supporting plate, after with a chain lateral pin on jack piston rod top on jointed shaft and the supporting plate being connected, again two jack on the supporting plate are suppressed, piston rod stretches out, and lateral pin is converted into pulling force tractive chain with the pressure of jack and extracts jointed shaft.
The utility model is simple to operate, safe and reliable, time saving and energy saving, no matter how serious the hinge hole on the hydraulic support stops up, all can extract jointed shaft easily under the effect of two jack, and can not damage hydraulic support, the course of work does not have potential safety hazard to operating personnel yet.
