Description
Technical field
The present invention relates in a kind of Mining Market the test detacher that breaks off relations.
Background technology
In Mining Market, may there is unhook phenomenon in winding cage, now relies on break catching apparatus to arrest safety rope to ensure the personal safety of staff.Therefore, the sensitivity of break catching apparatus and reliability most important.For testing reliability and the sensitivity of break catching apparatus, need when winding cage dispatches from the factory and install to carry out unhook test.The detacher that test of breaking off relations uses comprises hook, upper hook is hinged with lower draw-bar and pull bar respectively, described pull bar galianconism end and lower draw-bar end hook.
In unhook test, the upper hook of detacher is suspended on lifting gear, and winding cage is lifted on the lower draw-bar of detacher by wire rope, by lifting gear winding cage mentioned and pull pull bar to during test specified altitude assignment, lower draw-bar unclamps, and winding cage falls.Safety rope is arrested after break catching apparatus induction winding cage falls.
The shortcoming of this structure is: 1, because the weight of winding cage is 3t ~ 5t, lower draw-bar and pull bar hook place are by tight pressing, need greatly pulling force that lower draw-bar and pull bar can be made to depart from, the long-armed galianconism need being longer than pull bar far away of pull bar, considerably increase the quality of detacher, the quality of the common detacher for test of breaking off relations, at more than 25kg, hangs detacher effort.2, operated by pull bar, lower draw-bar and pull bar easily occur stuck, and winding cage cannot depart from, even if lower draw-bar is separated with pull bar, lower draw-bar hangs, and wire rope still may be hooked on lower draw-bar, test operation poor reliability.3, when there is lower draw-bar and pull bar is stuck or wire rope still may be hooked on lower draw-bar, winding cage easily falls suddenly, now, cutting tool need be used to be cut off by wire rope, waste time and energy, and the wire rope cut off can launch suddenly, easily be extracted into it staff, damage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lightweight, rapid operation, esy to use, safe and reliable, not to the unhook test detacher that staff damages.
The present invention is achieved in that
A kind of unhook test detacher, comprise shell, its special character is: the drive unit being provided with leading screw in the enclosure and being connected with leading screw, leading screw is provided with two screws, fixture block is respectively equipped with at two screw opposite sides, two fixture blocks are respectively equipped with arc notch, putting hole is formed after described two arc notch splits, suspension rod is provided with in putting hole, described suspension rod is stepped stem, its bigger diameter end diameter is greater than putting hole diameter, and its miner diameter end diameter is less than or equal to putting hole diameter, is provided with hook or suspension ring at the miner diameter end of described stepped stem.
The quantity of described leading screw is two, each leading screw is divided into two sections and the rotation direction of two sections of upper screw threads is contrary, described screw is sleeved on two leading screws respectively simultaneously, and two screws lay respectively at the different rotation direction section of leading screw, one end of two leading screws is connected with drive unit respectively, the other end of two leading screws is connected with gear respectively, two gears meshing, to realize steady folding.
Described leading screw is one, and described fixture block and screw are arranged up and down, is provided with limited block, with weight reduction around described screw.
Drop handle is provided with, so that hang outside described fixture block.
Described drive unit is made up of the rotating disk affixed with described leading screw, the strap be wrapped on rotating disk, the crank that is fixed in center of turntable, to reduce weight.
Described shell is connected with the banking stop corresponding with disk position, ties a knot to avoid cloth bag.
The motor that described drive unit is connected with direct supply by direct supply, the teleswitch be connected between power supply and motor form, and the output shaft of described motor is connected with described leading screw power, to realize automatic control.
Described fixture block is provided with roller with suspension rod correspondence position, to reduce friction when suspension rod falls.
The invention has the beneficial effects as follows:
1, the folding owing to adopting screw-nut to realize fixture block, reach the object of unhook, folding with convenience is easy, compared with existing detacher, substantially reduce volume, reduce weight, the quality of whole unhook test detacher is only 12kg ~ 20kg and facilitates staff to hang this unhook test detacher.
2, due to the horizontal folding of fixture block, suspension rod vertically falls, and avoid and occur stuck possibility, the success ratio 100% of unhook, reliability increases greatly.
3, owing to adopting leading screw to drive fixture block to be separated to realize breaking off relations, staff can, in comparatively distant positions realization unhook, can not be scraped and damage by the winding cage dropped, the wire rope got rid of, and unhook success ratio be high, without the need to using welding and cutting tool to remedy, security increases greatly.
