Description
Technical field
The utility model belongs to the bearing pin disassemblerassembler, the fast automatic detaching device of particularly a kind of bearing pin.
Technical background
Bearing pin is usually in the part that fixes on the machinery equipment, transferring power and be used for rising on instrument, the mould part positioning action.The bearing pin of main equipment is removed very difficulty, and there are many problems in currently used bearing pin method for dismounting such as hammering dismounting method, percussion hammer method, flyball method etc., and the one, labour intensity is big, the 2nd, be subjected to spacial influence big, the 3rd, dangerous, the 4th, waste time and energy, effect is bad.
Middle patent documentation CN2417969 discloses a kind of utensil of pulling pin, particularly a kind of hydraulic pin remover that is used to dismantle big bearing pin on the big machinery.It includes by two transverse slats up and down and fixedly constitutes the load framework by pull bar, load framework middle upper portion arrangement hydraulic jack, and hydraulic jack one end bearing is in the bottom surface of upper cross plate, and the other end is supported on end face on the block pressur plate; Pressing plate is by fixedlying connected the top pressing board that is positioned at the lower cross plate below with the depression bar that lower cross plate through hole cunning is joined; There are pull pin bolt and a lower cross plate centre bore cunning to join, and pass the centre bore of top pressing board and stretch out outside the top pressing board.Disclosed pin removal in the document exists to be subjected to spacial influence big, and utensil connects complicated, needs problems such as specific purpose tool, and operation is had relatively high expectations.
Disclosed bearing pin demolition technique is a kind of special technology in the 10th phase of " building safety " calendar year 2001 " the self-control hydraulic jack is removed K50/50 tower crane bearing pin technology " in addition, can only eject bearing pin from the non-end of packing into.Can only be when packing the end taking-up into when bearing pin, this technology can not be used.This technology is had relatively high expectations to bearing pin dismounting site space simultaneously." introducing a kind of novel bearing pin provision for disengagement " the related bearing pin provision for disengagement of " PORT OF SHANGHAI science and technology " the 1st phase in 2004 exists device bigger, the dismounting complexity of device.Need processing to use independent frock in the bearing pin unloading process.
More than device in use all exists and can't take out the problem of bearing pin automatically continuously, if when running into bearing pin and surpassing the stroke of pin pulling out device, all need repeatedly pin pulling out device to be installed, dismantled just and can fulfil assignment, so cumbersome.
Summary of the invention
The utility model is in order to solve the deficiency that prior art exists, to provide a kind of bearing pin fast automatic withdrawing device.
The technical solution of the utility model is: the bearing pin automatic device for taking out, comprise locking device, adjust silk braid, draw bar, jack and hydraulic pump, it is characterized in that, locking device (1) one end is provided with screw thread, the other end is connected by link pins (2) and draw bar (6) are inner, adjustment silk braid (4), two moving hollow plunger jack (7), bearing bottom plate (8) are set on the draw bar (6), adjust silk braid (4) and be connected by alignment pin (5) with two moving hollow plunger jack (7), two moving hollow plunger jack (7) are driven by hydraulic pump (12).
The interior silk braid internal diameter of described adjustment silk braid (4) is than the big 10-20mm of external diameter of bearing pin (15), and outer silk braid external diameter is adjusted the silk braid maximum length greater than bearing pin (15) and locking device (1) length sum than two little 40-60mm of moving hollow plunger jack (7) diameter.
Suspension ring (3) are housed on the outer silk braid of described adjustment silk braid (4).
Described two moving hollow plunger jack (7) diameter is than the little 40-60mm of bearing bottom plate (8) diameter.
Oblique cutting plate (9) is installed in the outer end of described draw bar (6).
According to the principle of active force and reaction force, utilize two moving hollow plunger jack to give and adjust silk braid with pressure, adjust silk braid and give two moving hollow plunger jack reaction forces, when the resistance of reaction force greater than bearing pin, bearing pin will shift out along draw bar.
In order to guarantee the continuity of operation, can reach and eliminate the gap that two moving hollow plunger jack stay because of stroke alteration by changing the length of adjusting silk braid.The outer silk braid of adjusting silk braid is fixed on the jack by alignment pin, and interior silk braid rotation power-saving is quick, operation repeatedly, thus realize continuously automatic purpose of taking out bearing pin.
The beneficial effects of the utility model are: simple in structure, and easy accessibility, tear down capability is strong, connects the positioning accuracy height, can self-locking, labor strength is little.The two moving hollow plunger jack active force that drives by the power fluid press pump is big, removes continuously fast.Can remove the different bearing pin of length easily.
