The specific embodiment
The automatic pin pulling out device of the hydraulic pressure of the utility model; 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.
Bolt Connector 5 comprises sleeve 11, separation pad 12, connecting bolt 13, connector 14.Sleeve 11 left sides are provided with external screw thread 17, and connector 14 adopts the hollow cylinder structures, and connector 14 is provided with screwed hole 15,, pin shaft hole 16, connector 14 can be changed according to the different size bearing pin.
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 18 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 the hydraulic pressure of the utility model is mainly used a kind of device that mine hydraulic bracket and main equipment alignment pin are extracted, and it has following innovative 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.
