The specific embodiment
The automatic pin pulling out device of hydraulic pressure of the present invention; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the automatic pin pulling out device of hydraulic pressure comprise shoring cylinder body 1, the cylinder cylinder body 2 of pulling pin, shoring piston rod 3, pull pin cylinder piston rod 4 and Bolt Connector 5.
The cylinder cylinder body 2 of pulling pin is located at shoring cylinder body 1 inside, the shoring cylinder body 1 and the cylinder cylinder body 2 nested, concentric assembling of pulling pin.
Shoring piston rod 3 adopts closed hollow shaft design, and the cylinder piston rod 4 of pulling pin is located at shoring piston rod 3 inside, cylinder piston rod and the shoring piston rod nested, concentric of pulling pin assembling.
The pull pin top of cylinder piston rod 4 is provided with internal thread hole, is connected with Bolt Connector 5 through internal thread.
The automatic pin pulling out device of hydraulic pressure is installed in and carries on the base for supporting 6, carries the adjustable height of base for supporting 6, and the automatic pin pulling out device of hydraulic pressure connects with Hydraulic Station 18.
Hydraulic Station is provided with hydraulic control system, and hydraulic control system is provided with pressure monitoring device and warning device, and operation conditions that can real-time monitoring device is also reported to the police.
The automatic pin pulling out device of hydraulic pressure of the present invention is mainly used a kind of device that mine hydraulic bracket and main equipment alignment pin are extracted, and it has following inventive point:
The automatic pin pulling out device of hydraulic pressure adopts the assembling of double hydraulic cylinder cylinder body nested, concentric, and is simple in structure, saves the space, easy to use, can from equipment, extract bearing pin is disposable.
The automatic pin pulling out device shoring of hydraulic pressure piston rod adopts hollow shaft to install, and plays the effect of supporting and protecting the cylinder piston rod of pulling pin simultaneously.
The double hydraulic cylinder piston rod of the automatic pin pulling out device of hydraulic pressure adopts closed nested, concentric to install, and has guaranteed the stability of pin pulling out device in running.
The automatic pin pulling out device of hydraulic pressure adopts the special bolt connector, and Bolt Connector adopts the hydraulic quick coupler mode to connect with bearing pin, has guaranteed the versatility of pin pulling out device.
Further specify below in conjunction with the operation principle of accompanying drawing the automatic pin pulling out device of hydraulic pressure:
During use; Earlier with the automatic pin pulling out device of hydraulic pressure its centre-height of position adjustment according to the equipment bearing pin of dismantling; Hydraulic Station gets into the cylinder of pulling pin at hydraulic control system effect downforce oil from hydraulic fluid port 9; The cylinder piston rod 4 of under the effect of control oil, pulling pin stretches out, and reaches range and stops, and the automatic pin pulling out device of hydraulic pressure links up through Bolt Connector 5 and bearing pin then; Hydraulic Station gets into shoring at hydraulic control system effect downforce oil from hydraulic fluid port 7; Shoring piston rod 3 stretches out under the effect of control oil, reaches range and stops, and the stroke of shoring piston rod 3 is greater than 20 millimeters of the strokes of the cylinder piston rod of pulling pin; And the aperture of shoring piston 3 is bigger 6 millimeters than the external diameter of Bolt Connector; The top that guarantees the shoring piston rod contacts with the equipment end face, and thrust is provided, and is then that the carrying base for supporting 6 of the automatic pin pulling out device of hydraulic pressure is fixing; After the fixation, shoring shoring piston rod 3 under the effect of control oil keeps original position; Control oil gets into the cylinder of pulling pin from hydraulic fluid port 10 then, and the cylinder piston rod 4 of pulling pin is shunk, and drives Bolt Connector 5 and shrinks; Bolt Connector 5 connects with bearing pin; Thereby can extract bearing pin is disposable down in the effect of control oil pressure, to feed control from oil-in 8 oily for hydraulic system after bearing pin was extracted, and the shoring piston rod is contracted to original position; Then bearing pin is removed, this moment, the whole process of pulling pin was accomplished.
