Technical field
The utility model relates to logistlcs technology field, particularly relates to a kind of gas spring vibration damping pallet.
Background technology
Pallet is a kind of logistics equipment of being convenient to mechanized handling, transporting goods, and is the important packing device in logistics system.In logistics operation, the goods of transport or storage is piled up on pallet, form a carrying unit to facilitate mechanized handling and storage operation.At present conventional in logistics chain have wood pallets and a plastic pallet.
At present, pallet is all to adopt rigid posts to connect upper disk surface and lower card, lacks the effect of anti-vibration vibration damping.In the transportation of modern precision instrument and precision equipment, due to very high to the susceptibility of vibration, often need good anti-vibration measure.And existing pallet is because entirety is rigid construction, cannot set it as an anti-vibration link in goods transport process, in goods transport process, vibrate relatively great Yi and cause damage.In the time of the high-end precision instrument of transport or military hardware, Chang Bixu additionally uses special dampening apparatus, produces higher expense.The pallet that for this reason, need to have a vibration-damping function adapts to commodity transport that anti-vibration has relatively high expectations and the needs of storage.
The vibration damping emphasis of pallet is to reduce downward acceleration due to gravity.Aerification between pallet pop-up card and subiculum card, theoretical analysis points out that gas has higher compressibility, and along with its stiffness coefficient of variation of load is variable, its high frequency waveforms filtering effect is obvious, the vibration-proof structure that therefore, need to adapt to for the characteristics design of pallet.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and provides a kind of simple in structure, the gas spring vibration damping pallet of dependable performance.
For realizing the technical scheme that the purpose of this utility model adopts be:
A kind of gas spring vibration damping pallet, comprises pop-up card and subiculum card, between described pop-up card and subiculum card, is installed with gas spring; The pressure cylinder end portion of each described gas spring is fixedly connected with described subiculum card, and the piston rod end of each described gas spring is fixedly connected with described pop-up card.
The piston rod of each described gas spring is connected with described pop-up card and subiculum card with bolt by steel pad respectively with pressure cylinder part.
The bottom-to-top-height of described gas spring is 15-40cm.
Described gas spring respectively symmetry is installed on four bights between described pop-up card and subiculum card.
Compared with prior art, the beneficial effects of the utility model are:
1, vibration damping pallet of the present utility model is according to the constructional feature of pallet, adopt gas spring as the attaching parts that supports pop-up card and subiculum card, utilize gas spring to absorb a large amount of kinetic energy, reduced the impact of acceleration due to gravity to institute's cargo in pop-up card, realize the object of vibration damping.Simple in structure, cost is low, and reliability is high, can transport vibrating exigent sensitive instrument and equipment, makes the larger reduction of logistics cost of precision instrument, equipment.
2, vibration damping pallet of the present utility model adopts gas spring as vibration-proof structure, and speed is relatively slow, and dynamic force changes little, easily controls.
3, while using vibration damping pallet traffic of the present utility model, vibration damping pallet, in having reduced the vibration of goods, has reduced the impulsive force to vehicle too, thereby vehicle is further reduced the impulsive force of road, and vehicle can be advanced by pulsation-free.Damping of vibrations protection transporting cargo not only can well be provided, can also play to a certain extent the effect of protection vehicle and road.
4, the gas spring height in vibration damping pallet of the present utility model is 10-40cm, can ensure best effectiveness in vibration suppression.
Brief description of the drawings
Figure 1 shows that the block diagram of the utility model gas vibration damping pallet;
Figure 2 shows that the front view of the utility model gas spring vibration damping pallet.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model gas spring vibration damping pallet as Figure 1-Figure 2, comprises pop-up card 1 and subiculum card 2, between described pop-up card 1 and subiculum card 2, is installed with gas spring 3; The pressure cylinder part of each described gas spring 3 is fixedly connected with described subiculum card 2, and the piston rod of each described gas spring 3 is fixedly connected with described pop-up card 1.
In the present embodiment, the piston rod of each described gas spring 3 is connected with described pop-up card and subiculum card with bolt by steel pad 4 respectively with pressure cylinder part.
In order to reach best effectiveness in vibration suppression, the bottom-to-top-height of described gas spring is 10-40cm.Described gas spring 3 respectively symmetry is installed on four bights between described pop-up card 1 and subiculum card 2.
Damping test:
1, test method: first open vibrobench, the utility model gas spring vibration damping pallet is placed on vibrobench, and subiculum card 2 and test cell are fixed; A vibration acceleration sensor is placed on and in subiculum card, carries out initial alignment.After demarcation, will test with load weight (about 265kg) be loaded in pop-up card 1.The acceleration pick-up that is fixed on subiculum card 2 is taken off, be fixed on weight and compress.Set test cell oscillation frequency, make it to produce vibration, the vibration acceleration data after vibration is stable in random acquisition weight 3S; Data acquisition is complete, shuts down and set the required frequency of vibration next time, repeats said process.According to the method described above the utility model gas spring vibration damping pallet is changed and adds the weight of loads simultaneously, and gather weight vibration data.Under the prerequisite identical with method with above-mentioned condition, be conventional wooden pallet by the utility model gas spring vibration damping pallet-changing, and carry out vibrating data collection to loading same weight on it, using the contrast groups as effectiveness in vibration suppression.
Experiment vibration frequency range is 0HZ---100HZ, and experiment oscillation frequency is spaced apart 5Hz.
2, test pallet dimension used:
(1) pop-up card and subiculum card 600mm × 600mm
(2) gas spring: high 10cm, product type 900N, operative norm: JB/T8046.1-1996
