The specific embodiment
Below the utility model is described in further detail.
Extremely shown in Figure 7 as Fig. 1, the utility model sectional track comprises two rail, a rail conduct in these two rail is rail 300 fixedly, and another rail is installed on a plurality of rail variable pitch devices 100 as removable rail 200, and each section of this removable rail 200 is fixed on this rail variable pitch device 100 via a fixed component.
Extremely shown in Figure 6 as Fig. 4, this rail variable pitch device 100 comprises a base plate 101, be welded with a sliding component 102 on this base plate 101, this sliding component 102 is the hollow cuboid that a cross section is hollow, on the end face of this sliding component 102, offer the slippage opening 103 of a strip, the two ends of this slippage opening 103 offer a bolt respectively and insert mouth 104, offer many group pins hole at these slippage opening 103 places, every group of pin hole is made of two pin holes 105, and two pin holes 105 in every group of pin hole are symmetricly set in the both sides of this slippage opening 103.
As shown in Figures 2 and 3, this fixed component comprises fastener 402, bolt 401, nut 403 and pin 404.This removable rail 200 is placed on the corresponding position of sliding component 102 end faces of this rail variable pitch device 100 by actual gauge requirement, the base in these removable rail 200 outsides and corresponding one group of pin hole are contiguous, the base of these removable rail 200 both sides respectively via with nut down mode insert by bolt that mouthful 104 bolts 401 that slip into slippage opening 103 wear that a fastener 402 backs are spirally connected with a nut 403 and the end of this fastener 402 of be spirally connected by this bolt 401 and nut 403 to push compresses downwards, pin joint one pin 404 in each pin hole 105 in this group pin hole on the base in contiguous these removable rail 200 outsides, the pin 404 of this pin joint is used to replace removable rail 200 and prevents this removable rail 200 slippage laterally.
In reality was made, the two ends of sliding component 102 can be made as uncovered, and this is uncovered as clean out 106, and as Fig. 6, like this, the staff can clean the dust and dirt of sliding component 102 inside easily by this clean out 106.
During installation, with respect to mounted fixedly rail 300, a plurality of rail variable pitch devices 100 are installed on the railway line of regulation, the spacing a between each rail variable pitch device 100 sets according to actual demands of engineering.In the enforcement, rail variable pitch device 100 can be located on steel column or concrete column or concrete integral channel bed or the track service pit pool wall according to actual field situation.Then, one section removable rail 200 is shelved on sliding component 102 end faces of rail variable pitch device 100, according to current requirement to the rail gauge, should removable rail 200 adjust to the right place (location, plan-position), at this moment, the base in these removable rail 200 outsides should be adjoining with corresponding one group of pin hole.Then, with two bolts 401 with nut down state and respectively the bolt by two ends insert mouthfuls 104 and slip into slippage opening 103, until the base place of slippage to these removable rail 200 both sides.Then, each side for removable rail 200 bases, one fastener 402 is located on the bolt 401, at this moment, the end of this fastener 402 be positioned at rail 200 bases above, then, one nut 403 is spirally connected with this bolt 401, be subjected to this bolt 401 and pushing that nut 403 is spirally connected, the end of this fastener 402 is adjacent to the base of removable rail 200, thereby the combination of this bolt 401, nut 403 and fastener 402 makes the base of removable rail 200 be downward impaction state.After each side on removable rail 200 bases all is downward impaction state, pin joint one pin 404 in each pin hole 105 in this group pin hole on contiguous this base, removable rail 200 outside prevents this removable rail 200 slippage laterally to replace removable rail 200 by pin 404.At last, the every section rail that is fixed on the rail variable pitch device 100 is spliced, thereby finished the installation task of the removable rail 200 of whole piece.
When needing conversion fixedly during the gauge of 200 of rail 300 and removable rail, the pin 404 in the outside is extracted, unclamp nut 403, with removable rail 200 slippages to the gauge position that requires, nut 403 is spirally connected tightly again, make the combination of bolt 401, nut 403 and fastener 402 compress the base of removable rail 200 both sides downwards, pin joint one pins 404 in each the pin hole 105 in this group pin hole on contiguous this base, removable rail 200 outside are got final product.
In the practical application, the group number in the pin hole at these slippage opening 103 places can design according to actual needs.For example, these slippage opening 103 places can be provided with two groups of pin holes, to form unidirectional mobile sectional track.Again for example, these slippage opening 103 places can be provided with three groups of pin holes, and to form two-way mobile sectional track, sectional track as shown in Figure 1 is two-way mobile track.
The position (just organizing the distance between the pin hole, as shown in Figure 4 D1, D2) that every group of pin hole is located on the sliding component 102 can need and be provided with by actual rail spacing.As Fig. 7, reasonable setting has been carried out by rail spacing conversion requirement in the position of every group of pin hole on sliding component 102, thereby make that fixedly rail 300 is arranged on the circuit P4, and removable rail 200 can be arranged on request on arbitrary the circuit among the circuit P1 to P3.For example, the removable rail 200 among Fig. 1 has been arranged on the circuit P1.
As Fig. 7, the distance between arbitrary the circuit among circuit P4 and the circuit P1 to P3 is the rail gauge.In actual applications, the distance between circuit P4 and circuit P1, P2, the P3 can be set at 1000mm, 1067mm, 1435mm respectively, and this is common rail arrow gauge substitute mode.In addition, the distance between circuit P4 and circuit P1, P2, the P3 also can be set at 1435mm, 1520mm, 1676mm respectively, and this is common rail broad gage substitute mode.
The utility model has the advantages that:
1, according to actual requirement, but the rail variable pitch device horizontal cross in the utility model changes the position of removable rail, thereby change the fixedly distance between the rail and removable rail, make the locomotive of multiple gauge, vehicle can be produced or overhaul on a track, the vehicle of promptly producing or overhaul any gauge just is transformed into the gauge of any length, reduced manufacturing, the quantity of ground rail between tool car, when saving the workshop floor space, satisfied the domestic and international locomotive of multiple gauge, the production of vehicle and the requirement of maintenance are railway locomotive, the manufacturing of vehicle and the maintenance condition of providing convenience.
2, the end of the sliding component in the utility model is made as uncoveredly, and it is uncovered and clean the dust and dirt of sliding component inside easily by this to help the staff.
3, the removable rail outside in the utility model is connected with pin, and this pin can be replaced removable rail, thereby prevents the slippage laterally of removable rail, has guaranteed the safe in utilization of track.
4, the utility model is simple in structure, and is safe and reliable, and part strength is guaranteed, easy and simple to handle, is easy to installation and removal, highly versatile.And materials of the present utility model are common, adopt welding procedure to make, and production and processing is very convenient, general factory all have ready conditions self-control, process.
The above is preferred embodiment of the present utility model and the know-why used thereof; for a person skilled in the art; under the situation that does not deviate from spirit and scope of the present utility model; any based on conspicuous changes such as the equivalent transformation on the technical solutions of the utility model basis, simple replacements, all belong within the utility model protection domain.
