Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
A kind of conical coil spring formula buffer, during to highway transport, railway transport, marine transportation, to steel, buffer function has been reinforced in the binding of industrial wheeled equipment, large cargo and the transportation of heavy packages case Container Loading.This buffer is provided with and connects pressing plate 1 and conical spring 2, connects pressing plate 1 and comprises that first connects pressing plate 11 and be connected and connect pressing plate 12, and described conical spring 2 is arranged on first and connects pressing plate 11 and second and connect between pressing plate 12.Conical spring 2 refers to present the helical spring of conical in shape, and the spring ring at the two ends of this helical spring 2 is arranged from large to small.First connects pressing plate 11 connects with being connected the rope that pressing plate 12 connects respectively fastening use, and the tension force that is subject to rope when buffer is done the used time, and described first connects pressing plate 11 connects pressing plate 12 and will form compressive loads to conical spring 2 with being connected.
As shown in Figure 4, the conical spring 2 that the present embodiment provides, it uses as Compress Spring, and during bearing load, before spring coil did not occur and be dead, this camber of spring was directly proportional to load, and as shown in Figure 5, Eigenvector is linear section on P-F figure; When load when increasing gradually, spring ring begins to occur and dead from large end, along with and dead spring ring increase, the corresponding minimizing of number of active coils, spring rate also increase gradually, until spring ring is pressed also fully, this one-phase distortion is non-linear with the relation of load, and the characteristic line segment is cumulative type on P-F figure.The rigidity of conical spring 2 is variate, and its cone angle is larger, and the variance ratio of the natural frequency of vibration of this spring is higher, and is more favourable for the resonance that relaxes or eliminate in transportation.
Compare with cylindrically coiled spring, conical spring can bear larger load in identical overall sizes situation, and can produce larger distortion, and the spring total head and the time, highly smaller.In addition, the stability of conical spring when stressed is also relatively good, compares with cylindrically coiled spring, has larger lateral stability.
can be provided with between the connection pressing plate 1 of buffer and connect guide rod 3, 3 pairs first of this connection guide rods connect pressing plates 11 and connect pressing plate 12 and play connection with being connected, the effect of supporting, and connecting guide rod 3 can be divided into the first connection guide rod 31 and be connected connection guide rod 32, they all will pass first and connect pressing plate 11 and be connected connection pressing plate 12, as illustrated in fig. 1 and 2, first connects guide rod 31 connects guide rod 32 and is connected with respectively fastening rope with being connected, when the tension force that is subject to fastening rope is done the used time, first connects guide rod 31 drives the first connection pressing plate 11, second connects guide rod 32 drives the second connection pressing plate 12, thereby make first to connect pressing plate 11, second connects 12 pairs of conical springs 2 of pressing plate compresses.
Above-mentioned conical spring 2 adopts the even number configuration, and conical spring 2 is equally divided into two-part, the placement direction of this two-part conical spring 2 is just in time opposite, the big or small extreme direction that is conical spring 2 is opposite, this conical spring can be divided into forward conical spring 21 and reverse conical spring 22, as shown in Figure 1, the small end of forward conical spring 21 is upper, and the large end of reverse conical spring 22 is upper.And, the quantity of conical spring 2 is preferably four, being arranged on abreast described first with the form of parallel connection connects pressing plate and second and connects between pressing plate wherein, two forward conical springs 21 and two balanced arrangements of reverse conical spring 22, arrange as criss-crossing, the mechanical property that is subject on connection pressing plate 1 with the assurance buffer is identical.
For connecting pressing plate 1 and the annexation that is connected guide rod 3, can adopt kinds of schemes.For example, can connect guide rod 31 with first and pass second and connect pressing plate 12 and is connected pressing plate 11 with first and be fixedly connected with, connect guide rod 32 with second simultaneously and pass first and connect pressing plate 11 and be connected pressing plate 12 connections with second.As shown in Figure 3, the scheme of employing preferred for this invention is: described connection guide rod 3 all adopts screw rod, and first connects guide rod 31 passes described the first connection pressing plate 11, forward conical spring 21 and the connection pressing plate 12 of being connected successively; Described second connects guide rod 32 passes described the second connection pressing plate 12, reverse conical spring 22 and the connection pressing plate 11 of being connected successively.Connect guide rod 31 first like this and connect guide rod 32 and be subjected to tension force to do the used time with being connected, first connects guide rod 31 connects guide rod 32 and just can drive accordingly first and connect pressing plate 11 and be connected connection pressing plate 12 with being connected.When forward conical spring 21 and oppositely conical spring 22 be respectively in the situation of two, can connect guide rod 31 with first and connect guide rod 32 correspondences and be set to respectively two with being connected.
Buffer is provided with and draws earrings 4, is used for connecting fastening rope.Generally draw earrings 4 can be set to two, and draw earrings 4 and be connected guide rod and be fixedly connected with.If connecting guide rod 3 is all under the situation of screw rod, this programme can draw one of them earrings 4 to be connected on described the first connection guide rod 31 by nut, and draws earrings 4 to be connected on described the second connection guide rod 32 by nut another one.
In goods is bundled the process of reinforcing, along with the tension of tension device to rope, the connection guide rod 3 of buffer is drawn out from connect pressing plate 1, connects guide rod 3 and is provided with the scale demonstration, be carved with pretightening force size situation and show, can realize the quantization operation to pretightening force.
As shown in Figure 3, in buffer is hit process, for the destruction that prevents that impact force from causing, added limited post 6 designs in the middle part of buffer is positive, limited post 6 adopts the moulding material with damping performance.When buffer is subject to impacting, be arranged on first connect pressing plate 11 be connected connect limited post 6 on pressing plate 12 will be preferential and be combined, realize the damping purpose by plastic deformation; Also volute spring 2 and whole buffer device are played a protective role simultaneously, and then increased working life and the Security of buffer.
Conical coil spring formula buffer working method is to be connected between lash rope, and for example, an end draws earrings 4 to be connected on the goods that must reinforce, and the other end draws earrings 4 to connect fastening on node of carrier vehicle.According to impulse principle:
Ft=m（u-v）
F: impact force;
t; Working time of collision;
U: the speed before impacting;
V: the speed after impact.
Goods to lash rope, forms compression to conical coil spring with impact loading on buffer when being subject to impacting.In this process, extended the action time of impact force, and then subdued the peak value of impact force.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
