Description

The Line for Passenger Transportation fastener is accurately installed frock

Technical field

The utility model relates to a kind of frock that the Line for Passenger Transportation fastener is accurately installed, more specifically say so to be used to make Line for Passenger Transportation with WJ-7 type fastener accurate location and installation on the track plate, and the gauge of assurance circuit and rail to special tooling.

Background technology

WJ-7 type fastener is by the independent research of China railway research institute, is exclusively used in to lay the fastener that 250km/h～350km/h does not have quarrel non-shoulder Line for Passenger Transportation, and in the laying of Shanghai and Nanjing inter-city passenger rail, this type fastener has obtained large-scale promotion and application at present.The great advantage of WJ-7 type fastener is exactly that gauge can steplessly be adjusted, but relative other Line for Passenger Transportation fasteners, and its later stage adjustment difficulty is big, the adjustment time is long, has prolonged the laying cycle.

The utility model content

The utility model is for avoiding prior art that the problem that WJ-7 type fastener exists is installed, provide a kind of Line for Passenger Transportation fastener that frock accurately is installed at WJ-7 type fastener, at the gauge that guarantees laying-out and rail under prerequisite accurately, reduce and adjust difficulty, reduce the accurate adjustment time in later stage of circuit, the reduction of erection time.

The utility model technical solution problem adopts following technical scheme:

The design feature that the utility model Line for Passenger Transportation fastener is accurately installed frock is:

Be provided as the rectangle posting of fastener installing and locating benchmark, described rectangle posting has two backstays that are parallel to each other, and keeping bar to be connected, the span between two backstays can be by keeping bar to regulate between two backstays; Mark has towards identical direction signs respectively on described two backstays;

Supporting setting can have caulking groove on the described locating piece by the locating piece of dowel fixes on the track plate, and the backstay in the posting can be embedded in the caulking groove and be fixed;

Fastener is located with the outside that its rail support groove outside shoulder block is resisted against backstay.

Design feature of the present utility model also is:

The supporting adjustment pad that is provided with, described adjustment pad are placed on the position location that is used to adjust fastener between the rail support groove outside shoulder block of fastener and the backstay.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, at the gauge that guarantees laying-out and rail under prerequisite accurately, greatly reduce the adjustment difficulty, reduced the accurate adjustment time in later stage of circuit, the reduction of erection time.

2, the utility model is simple in structure, easy to implement.

Number in the figure: 1 track plate, 2 insulated buffer plates, 3 is the WJ-7 iron chair, 4 is WJ-7 plain cushion piece, 5 anchor bolts, 6 springs, 7 is T type bolt, 8 nuts, 9 rail, 10 plain washers, 11 heavy-duty spring packing rings, 12 metallic pins, 13 locating pieces, 14 erection bolts, 15 backstays, 16 rest pads, 17 adjustment pads, 18 are WJ-7 type fastener, 19 direction signs, 20 rail support grooves outside shoulder block.

The specific embodiment

Figure 1 shows that present embodiment at the structural representation of WJ-7 type fastener after finishing assembling on the track plate 1, its composition comprises insulated buffer plate 2, WJ-7 iron chair 3, WJ-7 plain cushion piece 4, anchor bolt 5, spring 6, T type bolt 7, nut 8, rail 9, plain washer 10 and heavy-duty spring packing ring 11, and the laying of WJ-7 type fastener 18 on track plate 1 as shown in Figure 2.

Referring to Fig. 3, in the present embodiment, be provided as the rectangle posting of fastener installing and locating benchmark, the rectangle posting has two backstays that are parallel to each other 15, article two, between the backstay 15 keeping bar to be connected, the span between two backstays 15 can be by keeping bar regulate; Mark has towards identical direction signs 19 respectively on two backstays 15;

Fig. 3, Fig. 4 and shown in Figure 5, supporting setting can be fixed in locating piece 13 on the track plate by pin 12, on the locating piece 13 caulking groove is arranged, and the backstay 15 in the posting can be embedded in the caulking groove to be fixed;

Fig. 6, shown in Figure 7, WJ-7 type fastener 18 fasteners are located with the outside that its rail support groove outside shoulder block 20 is resisted against backstay 15.

Shown in Figure 7, in the present embodiment, the supporting setting adjusted pad 17, adjustment pad 17 is placed between the rail support groove outside shoulder block 20 and backstay 15 of fastener.

In concrete the enforcement:

As shown in Figure 2, WJ-7 type fastener 18 is laid on track plate 1, its second node place, middle orbit plate 1 front and back, and paving location is vacated, and is used for the location of later stage track plate 1, and the installation frock in the present embodiment also is to utilize this room, two places to position.
