The specific embodiment
Below in conjunction with the specific embodiment content of the present utility model is described, the description of this part only is that exemplary and indicative, concrete descriptive language and order should not have any restriction to protection domain of the present utility model.
As shown in Figure 1, the shallow hole formula rolling stock that embodiment one provides leads ride, comprises vehicle frame 3, a plurality of rail wheel 1, a plurality of breast wheel 2, uplink path section 4, and described vehicle frame 3 comprises left vehicle frame 31, right vehicle frame 32 and a plurality of vertical hinge 5.For clear this routine structure of describing, among the figure, also show rolling stock 01.Following description is reference with the lateral cross section of vehicle frame 3, is the left side with a side of vehicle frame 3, and opposite side is the right side, and described lateral cross section is vertical with the trend of uplink path section 4.
The left side of the right side of described left vehicle frame 31 and right vehicle frame 32 is hinged and connected with vertical hinge 5; On left side vehicle frame 31 and the right vehicle frame 32 orbital segment is housed respectively; Two orbital segments on described left vehicle frame 31 and the right vehicle frame 32 are formed a uplink path section 4 complete, that rolling stock 01 can be walked, when transportation rolling stock 01, rolling stock 01 can be parked on the uplink path section 4; Described a plurality of rail wheel 1 is installed in the left side of left vehicle frame 31 and the left side of right vehicle frame 32, and rail wheel 1 direction of travel is vertical with the trend of uplink path section 4; Described breast wheel 2 order on the direction consistent with uplink path section 4 trends is installed on the corresponding vertically hinge 5, is used to the centre portion of vehicle frame 3 to provide support power, and the direction of travel of described breast wheel 2 is consistent with rail wheel 1 direction of travel.In this example, breast wheel 2 is walked on same track with rail wheel 1.
According to material mechanics principle, as shown in Figure 2, the amount of deflection of the maximum of crossbeam, just the maximum distortion of crossbeam is: PaL
2(3-4a
2)/24EI, wherein P is that uplink path is to leading the application force that ride applies; A is the horizontal throw between uplink path and the homonymy rail wheel 1, the horizontal throw between just outer origin of force and the homonymy rail wheel 1, and the width of uplink path is constant, and the width that leads between the ride rail wheel also just remains unchanged, and a also remains unchanged; E is a modulus of elasticity, and is irrelevant with shapes such as the thickness of the size of object and object, length, only is decided by the character of material, the different modulus of elasticity differences of material, because the material of crossbeam is basic identical, elastic modulus E also remains unchanged; The I moment of inertia also remains unchanged, and therefore, leads under the ride width unmodified situation in maintenance, and P, a, E, I remain unchanged.In this example, because vehicle frame 3 is divided into two parts, span L is original half, and when stressed P was identical, the maximum of vehicle frame 3 crossbeams was scratched the end and can be reduced to original 1/4.Therefore, lead ride with shallow hole formula rolling stock of the prior art and compare, under the load same case, the deformation ratio that crossbeam is bent down is less, and the rigidity of crossbeam improves greatly.Specifically, left side vehicle frame 31 and right vehicle frame 32 are separately stressed, when stressed as mechanism's bearing load independently, because span is smaller, the lower bending shape that the stressed back of crossbeam produces becomes less, under the load same case that bears, can reach required rigidity with less crossbeam, therefore can alleviate the total weight that leads ride; Simultaneously, left vehicle frame 31 is hinged and connected by vertical hinge 5 with right vehicle frame 32, can guarantee to be installed in the distance of two orbital segments on left vehicle frame 31 and the right vehicle frame 32, guarantees that two orbital segments form one section uplink path section 4 that complete rolling stock can be walked.
According to above-mentioned description as can be seen, vertically the effect of hinge 5 is the location of crossing for fear of vehicle frame 3, when avoiding the straightness accuracy of downing track unit length out of reach requirement, makes rail wheel and breast wheel discontinuity, and rail wheel 1 or breast wheel 2 are damaged.Those skilled in the art can understand, and levy the guarantor under the situation of corresponding working accuracy, can adopt the scheme that only adds a breast wheel 2 at the middle place of vehicle frame 3 that the rigidity of leading ride is increased, and alleviate and lead ride weight.In addition, keeping under the vehicle frame 3 middle pivotally attached situations, as long as in a lateral direction, breast wheel 2 is between two rail wheels 1, just can increase the rigidity of leading the ride crossbeam, preferred positions is the centre of vehicle frame 3 lateral cross section, can make vehicle frame 3 stressed more even like this.
In this example, breast wheel 2 can exchange with rail wheel 1, can facilitate for the manufacturing and the installation of leading ride, needn't distinguish use.Those skilled in the art understand, and lead the smaller situation in ride midway location space in order to satisfy, and breast wheel 2 also can be littler than rail wheel.In addition, breast wheel 2 also is not limited to walk on same track with rail wheel 1, for being provided with independent track, breast wheel 2 can realize that also the utility model alleviates the purpose of leading ride weight, optimized technical scheme is, breast wheel 2 is walked on same track with rail wheel 1, so just can utilize the existing ride basis of leading, needn't carry out corresponding transformation the existing ride basis of leading.
The shallow hole formula rolling stock that embodiment one provides leads ride under the prerequisite of the rigidity that guarantees, has alleviated the weight of leading ride, but when bearing the large-tonnage load, the wheel load of breast wheel 2 is just bigger; According to the requirement of design regulation, the wheel load of breast wheel 2 is bigger, and the diameter of breast wheel 2 also will increase; But because the height that leads in the middle of the ride is limited, the height of breast wheel 2 is restricted, and can not infinitely increase, and therefore, breast wheel 2 diameters of said structure can not satisfy the requirement of transportation large-tonnage rolling stock.
On the basis of embodiment one, embodiment two just provides a kind of shallow hole formula rolling stock that can satisfy the requirement of transportation large-tonnage rolling stock to lead ride, as shown in Figure 3, shallow hole formula rolling stock in this example lead ride comprise rail wheel 1, breast wheel 2, by left vehicle frame 31, right vehicle frame 32 and vertical vehicle frame 3 and the uplink path section 4 formed of hinge 5, also comprise a plurality of driving supports 21; For clear this routine structure of describing, among the figure, also show rolling stock 01.Described driving support 21 is hinged and connected with corresponding vertical hinge 5, and on the direction consistent with uplink path section 4 trends serial arrangement; Two breast wheels 2 that are equipped with on each described driving support 2, and two breast wheels 2 can be walked on same track.Other are identical with embodiment one, repeat no more herein.
The principle that the shallow hole formula rolling stock that this example provides leads ride raising transverse beam rigidity is identical with last example, repeats no more herein.
In this example, because two breast wheels 2 are housed on the vertical hinge 5 between left vehicle frame 31 and the right vehicle frame 32, therefore a strong point just provides support power by two breast wheels 2, when load is the large-tonnage rolling stock, two breast wheels 2 just can bear large-tonnage load jointly, each breast wheel 4 load of bearing reduces like this, wheel load between breast wheel 2 and its walking track is also just smaller like this, under the condition of the wheel load allowable that satisfies the design regulation requirement, what the diameter of breast wheel 2 can be provided with is smaller, so that breast wheel 2 is leading ride midway location layout, satisfy the requirement of transportation large-tonnage rolling stock.
In the last example, about also not being defined as, do not arrange two breast wheels 2 on the same driving support 21, also can be in vertical layout, promptly can on moving towards consistent direction, uplink path section 4 arrange, be that such layout can make two breast wheels 2 that are installed on the same driving support 21 not walk on same track, therefore in order to make the track that leads the ride basis simpler, optimized technical scheme is that two breast wheels 2 that are installed on the same driving support 21 are arranged on rail wheel 1 direction of travel, and two breast wheels 2 can be walked on same track.
Above-mentioned breast wheel 2 and vertical hinge 5 are installed together, though can alleviate under the prerequisite of leading ride weight, the rigidity that guarantees, but when transportation or installation, vertically hinge 5 makes the structure more complicated with being connected of breast wheel 2, and vertically hinge 5 is stressed bigger, easily impaired, therefore has for the position of breast wheel 2 and can improve part.
Embodiment three provides a kind of and has led ride with what breast wheel linked to each other with the vehicle frame that leads ride.As shown in Figure 4, the ride that leads that this example provides comprises that rail wheel 1, breast wheel 2, vehicle frame 3 comprise left vehicle frame 31, right vehicle frame 32 and vertical hinge 5, uplink path section 4; Same clearer for what structure was represented, also show rolling stock 01 among the figure.The right side of described left vehicle frame 31 and right vehicle frame 32 left sides are hinged and connected with vertical hinge 5; Described a plurality of breast wheel 2 makes up in twos, forms a plurality of middle wheels that comprise two breast wheels 2, and described a plurality of middle wheels are serial arrangement on the direction consistent with uplink path section 4 trends; Two breast wheels 2 of wheels are installed in the right side and right vehicle frame 32 left sides of left vehicle frame 31 respectively in the middle of same, and other structures are identical with embodiment one, repeat no more herein.
The principle that the shallow hole formula rolling stock that this example provides leads ride raising transverse beam rigidity is identical with embodiment one, repeats no more herein.
In this example, because the left side of left vehicle frame 31 is equipped with rail wheel 1, the right side is equipped with breast wheel 2, like this, after removing hinged between the left and right vehicle frame 31,32, the left halfbody of being made up of left vehicle frame 31, rail wheel 1 and breast wheel 2 itself can self-movement, and its width is to lead half of ride integral width; Equally, the right halfbody of being made up of right vehicle frame 31, rail wheel 1 and breast wheel 2 itself also can self-movement, and its width also is to lead half of ride integral width.Therefore, when ride is led in transportation, can be divided into two parts with leading the ride vehicle frame: left halfbody and right halfbody.Because left halfbody and right halfbody width are whole half of ride of leading, transportation is just very convenient like this; When ride is led in installation, as long as left vehicle frame 31 and right vehicle frame 32 are put in position, with vertical hinge 5 with left vehicle frame 31 and the right vehicle frame 32 hinged assemblings that just can realize leading ride.In addition, in this example, vertically hinge 5 is stressed smaller, has also avoided vertical hinge 5 stressed concentrating.
Certainly the breast wheel structure that goes up example can be identical with rail wheel, so that the two can exchange, and also can be different; Breast wheel can be walked on same track with rail wheel, also can not walk on the bar track.
In addition, bear load when little leading ride, because breast wheel 2 is stressed smaller, in the scope of wheel load allowable, breast wheel also can be made as one, with the diameter of breast wheel 2 be provided with smaller, make the position intermediate space can hold breast wheel, it can only be installed in the right side of left vehicle frame 31, also can only be installed in the left side of right vehicle frame 32, can only be that left vehicle frame or right vehicle frame can self-movements although it is so, but different can be implemented under the prerequisite that guarantees rigidity alleviate the purpose of the overall weight of leading ride.
The structure of the lateral cross section of leading ride has below only been described, those skilled in the art can understand, because rolling stock is long, in the vertical, shallow hole formula rolling stock leads ride and also is provided with many group rail wheels and breast wheel, in order to satisfy different requirements, in a longitudinal direction, it is corresponding that the strong point that provides with rail wheel also is provided the strong point that the combination of breast wheel or breast wheel provides, and also can be less than the strong point that the combination of rail wheel provides.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
