Abstract
The utility model provides a double-block type ballastless track angle adjustable track bent frame which comprises a bent frame, a tool track and a supporting frame and is characterized in that an angle adjusting block is connected to the supporting frame and connected with a lifting adjusting screw in a penetrating mode. The angle adjusting block and the lifting adjusting screw are main parts for adjustments of the height and angles. The angle adjusting block can be driven to move vertically through rotation of the lifting adjusting screw, and therefore vertical movement of the track bent frame can be achieved., Angle adjustment of the track bent frame can be achieved through locating pins inserted into different locating holes of the supporting frame and the angle adjusting block, and therefore the track bent frame can be enabled to satisfy practical demand of a roadbed.
Description
Technical field
The utility model relates to a kind of track framed bent, specifically a kind of double-block type ballastless track adjustable angle track framed bent.
Background technology
Non-fragment orbit is the advanced person's of the world today track technology, and its advantage is very obvious, is particularly suitable for the needs of Development of High Speed Railway.Flourish along with the China Express Railway Line for Passenger Transportation, non-fragment orbit is constantly being applied, and growth momentum is swift and violent.In the double-block type ballastless track work progress, need to adopt the track framed bent that sleeper is adjusted to theoretical position, then joints cement disassembles described track framed bent after theing cement solidifies.Because described track framed bent is in different states in different highway sections, therefore need to be when laying the track framed bent to the direction of track framed bent, just, horizontal level adjusts, to satisfy actual construction requirement.
The utility model content
The purpose of this utility model just provides a kind of double-block type ballastless track adjustable angle track framed bent, to satisfy in the angle adjustment requirement of respective stretch to the track framed bent.
The utility model is achieved in that a kind of double-block type ballastless track adjustable angle track framed bent, comprises framed bent, tool track and bracing frame, is connected to the angle adjustment piece at support frame as described above, and cross-under has the lift adjustment screw rod on described angle adjustment piece.
Some locating holes for alignment pin grafting location are set respectively on described angle adjustment piece and support frame as described above.
Be provided with the groove that is complementary with described tool track at described framed bent, described tool track is placed in the described groove; Between described framed bent and described tool track, be connected to splice bar.
Lift adjustment screw rod in the utility model and angle adjustment piece are the critical piece of height adjustment, angle adjustment, by rotating the lift adjustment screw rod, can drive the angle adjustment piece and move up and down, and then realize moving up and down of track framed bent; By alignment pin is inserted in the different locating holes on bracing frame and the angle adjustment piece, can realize the adjustment to track framed bent angle, thereby can make the track framed bent satisfy the actual demand of roadbed.
The utility model is the raising in conjunction with the high-speed railway construction level, the raising that the precision of construction equipment, rigidity are required and the optimal design of carrying out, under prerequisite easy to use, rigidity has been improved 30%, increase simultaneously the angular adjustment ability that adapts to freeboard section construction needs, in use had lightweight, the advantages such as rigidity is large, efficient is high, easy and simple to handle, labour intensity is low, wide accommodation.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of track framed bent shown in Figure 1.
Fig. 3 is the structural representation of bracing frame.
Fig. 4 is the structural representation of angle adjustment piece.
Among the figure: 1, lift adjustment screw rod, 2, connecting pin, 3, framed bent, 4, fish-bolt, 5, nut, 6, tool track, 7, bracing frame, 8, holding pin, 9, the angle adjustment piece, 10, alignment pin, 11, fastening bolt.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises some framed bents that be arranged in parallel 3, framed bent 3 adopts the heavy wall rectangular tube to make, connect by two tool tracks 6 between the framed bent 3, tool track 6 is perpendicular with framed bent 3, and tool track 6 is placed in the groove that predefined and tool track 6 are complementary on the framed bent 3.Tool track 6 adopts and the formal same product of rail that uses, and is substituting good.Double-block type sleeper by with can realize being connected of tool track 6 formal accurate location of using rail in future.Be provided with bolt hole at framed bent 3 and tool track 6, the fish-bolt 4 by being complementary with described bolt hole, the nut 5 and the corresponding splice bar that are complementary with fish-bolt 4 can couple together framed bent 3 and tool track 6.Described splice bar has ramp structure, is provided with slotted hole on it, and the structure of this uniqueness can conveniently be adjusted precision.The flexible combination of framed bent 3 and tool track 6 can adapt to different construction requirements.
Be provided with the bracing frame 7 for supporting row frame 3 at the two ends of framed bent 3, bracing frame 7 is the lead frame structure, and its side plate is made with the monoblock steel plate, non-welding structure, thereby so that the rigidity of bracing frame 7 greatly increase.Be respectively arranged with connecting hole at framed bent 3 with the position that bracing frame 7 is connected, be connected by the connecting pin 2 that passes described connecting hole between framed bent 3 and the bracing frame 7.
The angle adjustment piece 9 that is provided with for the adjustment angle at bracing frame 7 reaches the vertical lift adjustment screw rod 1 that angle adjustment piece 9 is used for adjusting high and low position that passes.In conjunction with Fig. 3 and Fig. 4, be respectively arranged with a through hole and some locating holes at bracing frame 7 and angle adjustment piece 9, are connected with alignment pin by holding pin 8 between bracing frame 7 and the angle adjustment piece 9 and are connected, holding pin 8 passes respectively the through hole on bracing frame 7 and the angle adjustment piece 9, alignment pin 10 can be inserted in the different locating hole on bracing frame 7 and the angle adjustment piece 9, insert in the different locating holes by changing alignment pin 10, can realize to the track framed bent adjustment of angle.Also be provided with screwed hole on the bracing frame 7, fastening bolt 11 penetrates in the described screwed hole and can carry out fastening to bracing frame 7.Bracing frame 7 has the dual-use function of supporting row frame 3 and adjusting angle; Its processing and fabricating is simple and convenient, and production efficiency is high, and is with short production cycle.
Be provided with screwed hole at angle adjustment piece 9, lift adjustment screw rod 1 passes between described screwed hole and the angle adjustment piece 9 and is threaded.Rotate lift adjustment screw rod 1 and can drive angle adjustment piece 9 and move up and down, and then so that the track framed bent move up and down.Lift adjustment screw rod 1 is the critical piece of height adjustment and angle adjustment with angle adjustment piece 9, matching thread between lift adjustment screw rod 1 and the angle adjustment piece 9 is regular screw threads, simple in structure, lift adjustment screw rod 1 is more with the threaded engagement number of turns of angle adjustment piece 9, this be because: screw thread is when being subjected to External Force Acting, and load is not to be evenly distributed on each building ring of screw thread, but successively decreases from top to bottom, for avoiding stress to concentrate, therefore increased the number of effective coils of screw thread.
