Detailed description of the invention

As depicted in figs. 1 and 2, the utility model comprises some framed bents 4 be arranged in parallel, framed bent 4 adopts heavy wall rectangular tube to make, connected by two parallel tool tracks 6 between framed bent 4, tool track 6 is perpendicular with framed bent 4, and tool track 6 is placed in the groove matched with tool track 6 that framed bent 4 presets.Tool track 6 adopts and the product formally using rail same, substituting good.Double-block type sleeper is by realizing to formally using rail future accurate location with the connection of tool track 6.Connected by splice bar 5 between framed bent 4 and tool track 6, framed bent 4 and tool track 6 are provided with bolt hole, by framed bent 4 and tool track 6 being coupled together to the fish-bolt 7 that described bolt hole matches, the nut matched with fish-bolt 7 and corresponding splice bar 5.As shown in Figure 3, splice bar 5 has ramp structure, is provided with bar hole 11, and the structure of this uniqueness can facilitate Adjustment precision.Framed bent 4 and the flexible combination of tool track 6, can adapt to different construction requirements.

The two ends of framed bent 4 are provided with the supporting mechanism for supporting row frame 4, and described supporting mechanism comprises bracing frame 2, studdle 1, contiguous block 8 and angle adjustment bolt 9.Composition graphs 4, bracing frame 2 adopts heavy wall rectangular tube to make, bracing frame 2 is fixedly connected on the end of framed bent 4, specifically, the end connected with framed bent 4 at bracing frame 2 is provided with flanged plate 12, flanged plate 12 has bolt hole, and the flange bolt 3 matched by bolt hole can make to realize Flange joint between bracing frame 2 and framed bent 4.

Breach 15 is had in bracing frame 2 bottom, by breach 15, contiguous block 8 is set in bracing frame 2 inside, two vertical side walls relative on bracing frame 2 have lateral connection hole 14, as shown in Figure 5, horizontal axis hole 16 is had in one end of contiguous block 8, make bearing pin 10 through the connecting hole 14 of bracing frame 2 sidewall and the axis hole 16 of contiguous block 8, the hinged of bracing frame 2 and contiguous block 8 can be realized.

Through hole 13 is had at the top of bracing frame 2, vertical screw 17 is had at the middle part of contiguous block 8, through hole 13 is relative with vertical screw about 17, studdle 1 is from top to bottom through the through hole 13 on bracing frame 2 and the vertical screw 17 on contiguous block 8, and be threaded with contiguous block 8, rotational support screw rod 1, can adjust the high and low position of contiguous block 8.Studdle 1 is more with the threaded engagement number of turns of contiguous block 8, this be due to: screw thread is when by External Force Acting, and load is not be evenly distributed on each building ring of screw thread, but successively decreases from top to bottom, for avoiding stress to concentrate, therefore adds the number of effective coils of screw thread.

Locking member is provided with at the other end (one end relative with the one end having axis hole 16) of contiguous block 8, the position relative with the locking member on contiguous block 8 at the top of bracing frame 2 has through hole, through hole is welded with nut, angle adjustment bolt 9 through the nut at bracing frame 2 top and through hole, and the bolt head of angle adjustment bolt 9 stretch in the inner chamber of bracing frame 2 with the locking member clamping on contiguous block 8.

Particularly, as shown in Figure 5, the locking member of contiguous block 8 has hemi-spherical cavities 18, be provided with tapped circular bayonet socket 19 at the top of hemi-spherical cavities 18, the diameter of bayonet socket 19 is less than the diameter of hemi-spherical cavities 18.As shown in Figure 6, angle adjustment bolt 9 comprises bolt head 20 and screw rod, bolt head 20 is hemispherical dome structure, the diameter of bolt head 20 is slightly less than the diameter of locking member upper latch notch 19, between bolt head 20 and screw rod, be provided with the thin neck 21 that diameter is less than bolt head 20 diameter, the height of thin neck 21 is greater than the degree of depth of locking member upper latch notch 19.The top periphery of bolt head 20 is shaped with the external screw thread suitable with the internal thread on bayonet socket 19, and bolt head 20, through after the bayonet socket 19 on locking member, is connected in the hemi-spherical cavities 18 of locking member.

When the bolt head 20 of angle adjustment bolt 9 is stretched in the hemi-spherical cavities 18 on locking member, first the internal thread on the external screw thread at bolt head 20 top and bayonet socket 19 will be made to be interlocked, rotational angle adjustment bolt 9, the bayonet socket 19 of bolt head 20 on locking member is made to enter in hemi-spherical cavities 18, now the thin neck 21 of bolt head 20 upper end is positioned at the bayonet socket 19 on locking member, between thin neck 21 and bayonet socket 19 inwall, there is pore volume, make bolt head 20 free to rotate in the hemi-spherical cavities 18 of locking member.As long as contiguous block 8 one rotates a little, the internal thread of locking member upper latch notch 19 will no longer be interlocked with the external screw thread at bolt head 20 top, and then bolt head 20 can not be gone out along locking member upper latch notch 19, therefore, stretch into after in first spherical hollow space 18 of locking member at bolt head 20, bolt head 20 is connected in hemi-spherical cavities 18.

When needing adjusting angle, studdle 1 is made to be in relaxed state, studdle 1 pair of contiguous block 8 no longer applies any active force, and pass through bearing pin 10 between one end of contiguous block 8 and bracing frame 2 in hinged state, bolt head 20 clamping of angle adjustment bolt 9 is lived by the locking member on contiguous block 8 other end.At the top rotating angle adjustment bolt 9 of bracing frame 2, make angle adjustment bolt 9 to move or moves down, the movement of angle adjustment bolt 9 drives contiguous block 8 to move by locking member, that is: make contiguous block 8 with the bearing pin 10 of its one end for axle and rotating, thus realize the stepless changing of angle.
