Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the cylinder buffer device of the utility model preferred embodiment;
Fig. 2 is the plan view of cylinder buffer device shown in Figure 1.
The name of each label correspondence is called among the figure:
1 sliding mount, 2 collision blocks, 3 guide springs, 4 guide rods, 5 oil cylinders, 6 accumulators, 7 one-way valves, 8 need the object of buffering, 9 rolling bearings.
Embodiment
The utility model relates to a kind of cylinder buffer device that can play buffering, absorb momentum, it mainly comprises targeting part and oil pressure part, targeting part is used for and has very big momentum, needs the object of buffering to contact, and with its momentum transfer to oil cylinder, the kinetic energy that the oil pressure part then receives oil cylinder is converted into moving of hydraulic oil, and gas compression absorbs kinetic energy in the accumulator thereby finally force.
The structure of cylinder buffer device as shown in Figure 1, wherein targeting part comprises sliding mount 1, guide rod 4, guide spring 3, collision block 2, oil pressure partly comprises oil cylinder 5 with piston, accumulator 6, connect oil cylinder 5 and accumulator 6 oil pipe, be arranged on the one-way valve 7 on the oil pipe.
Need the object 8 of buffering directly to contact, bump sliding mount 1 with sliding mount 1.Sliding mount 1 moves axially along guide rod 4.In addition, be arranged with guide spring 3 on the guide rod 4, and guide spring 3 has the movement direction opposite effect power when being impacted with sliding mount 1, can slow down moving of sliding mount 1, strengthen cushioning effect.
Owing to need the impact force of 8 pairs of sliding mounts 1 of object of buffering might not promptly be parallel to guide rod 4; but the component that in most cases has other directions; therefore rolling bearing 9 is installed on sliding mount 1, as shown in Figure 2, can only moves axially along guide rod 4 to guarantee sliding mount 1.
Store hydraulic oil in the oil cylinder 5, oil cylinder 5 is provided with unique oil outlet that is communicated with accumulator 6.Piston one end is installed with collision block 2, and collision block 2 is positioned at sliding mount 1 by on the path that moves forward after clashing into, and is separated with a determining deviation with it towards sliding mount 1 ground.Therefore, when the object 8 of needs bufferings knocks sliding mount 1, drive sliding mount 1 when guide rod 4 moves, sliding mount 1 will firmly hit on collision block 2; Collision block 2 is fixedlyed connected with piston, thereby collision block 2 hit the back and drive piston and move, and hydraulic oil is squeezed out oil outlet.Piston and guide rod 4 be arranged in parallel, so its movement direction is consistent with sliding mount 1.
One end of oil pipe is connected with the oil outlet of oil cylinder 5, and the other end is connected to accumulator 6.Oil pipe adopts high-pressure oil pipe, can bear certain pressure, and oil pipe can not break when guaranteeing that hydraulic oil flows.The centre of oil pipe is provided with one-way valve 7, and it allows the hydraulic oil in the oil cylinder 5 to flow to accumulator 6, and does not allow the oil in the accumulator 6 to flow to oil cylinder 5.Also be parallel with adjustable throttle valve on the one-way valve 7, regulate from accumulator 6 to oil cylinder 5 hydraulic oil where necessary and reflux.
Accumulator 6 inside are provided with a dividing plate movably, and dividing plate is separated into two independent cavity with accumulator 6 inner spaces, and wherein a chamber is communicated with oil cylinder 5, and hydraulic oil is equipped with in inside, and another chamber is an enclosed cavity, and inside is gas by compression.Piston is impacted and is moved, force the hydraulic oil of oil cylinder 5 inside to enter in the chamber of accumulator 6 through oil pipe and one-way valve 7 from oil outlet, and then promote dividing plate and move to another chamber, compress the gas in this chamber, then energy is absorbed and is stored in the pressurized gas.
Hydraulic oil moves to accumulator 6 in the oil cylinder 5, and then hydraulic oil reduces in the oil cylinder 5, so also offers filler opening on the oil cylinder 5, and filler opening is connected with a hand pump, and hand pump can add to the hydraulic oil of outside in the oil cylinder 5, adjusts the oil pressure of damping device.The filler opening of oil cylinder 5 need be blocked in application, only reserves hydraulic fluid port.
When the object 8 of needs buffering bumps against sliding mount 1, sliding mount 1 moves along guide rod 4, guide spring 3 is compressed, run into collision block 2 until sliding mount 1, and force collision block 2 to drive piston then to move, hydraulic oil in the oil cylinder 5 is extruded and enters oil pipe, enter into accumulator 6 through one-way valve 7, the hydraulic oil that increases in the accumulator 6 promotes dividing plate, the chamber volume that gas is housed is reduced, gas in it is compressed, and initial kinetic energy is converted into the interior energy of the gas of compression, and making needs the energy of the object 8 of buffering by the GAS ABSORPTION in the accumulator 6.Gas in the accumulator 6 herein, can be various can compressed gas, as nitrogen, air etc.
Adopt cylinder buffer device of the present utility model; for the impacted object that need stop immediately; it will be zero reposefully that this device can make striking velocity moment, avoid the destruction of inertial force with the protection impacted object, and this device can be widely used in the bigger place that needs buffering of various impacts.Simultaneously, this device impact speed does not have strict restriction, and the occasion that can adapt to different bump dynamics by the gas pressures in the adjusting accumulator 6 and the mode of oil cylinder 5 interior oil pressure, oil pressure also can refuel by hand pump and adjust in the oil cylinder 5, certainly the filler opening of oil cylinder 5 need be blocked in application, only reserves hydraulic fluid port.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
