Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of subway track-laying integral roadbed construction, and in particular relates to a direction regulating rod for fine adjustment of track rows in a shield section. Background Art
[0002] During the subway track laying process, the integral roadbed plays a connecting role, transmitting the longitudinal, transverse and vertical loads generated by the train operation. The quality of its construction determines the success or failure of the integral roadbed track structure and affects the safety and comfort of train operation.
[0003] Conventionally, when constructing the integral roadbed in the shield section, there is no action point for adjusting the direction of the track row, and it is often necessary to drill holes and plant reinforcement on the shield segments or directly push them onto the gantry crane running rail piers. Planting reinforcement on the segments will damage the appearance quality and even the physical quality of the segments, which may easily cause quality risks to the long-term operation of the subway; directly pushing them onto the running rail piers may easily cause running rail gauge deviation, which will affect the safe operation of the gantry crane. Utility Model Content
[0004] The utility model is designed to solve the problem that there is no action point for the direction adjustment of the rail row when constructing an integral roadbed in a shield section.
[0005] The utility model provides a direction adjusting rod for fine adjustment of track rows in a shield section, comprising a tray for supporting a steel rail, a sleeve for connecting with connecting bolts of a shield segment, and an adjusting rod capable of adjusting length; one end of the adjusting rod is connected to the tray through a first hinge joint, and the other end is connected to the sleeve through a second hinge joint; the adjusting rod is supported between the steel rail and the shield segment through the tray and the sleeve, the rotating shafts of the first hinge joint and the second hinge joint are parallel to the length direction of the tunnel, and the tray and the sleeve on the adjusting rod can swing in the cross section of the tunnel.
[0006] Furthermore, the adjusting rod includes a hollow steel pipe and a screw; threads are engraved in the two side pipe openings of the hollow steel pipe, and the threads in the two side pipe openings have opposite rotation directions. The two screws are respectively screwed with the threads of the two side pipe openings of the hollow steel pipe, and the ends of the two screws are respectively connected to the first hinge joint and the second hinge joint.
[0007] Furthermore, the ear plate at the end of the screw rod extends into a pair of ear plates on the tray and is connected by a pin to form a first hinge joint; the ear plate at the end of the screw rod extends into a pair of ear plates on the sleeve and is connected by a pin to form a second hinge joint.
[0008] Furthermore, the middle of the hollow steel pipe is provided with insertion holes distributed around the ring.
[0009] Furthermore, the contact surface between the tray and the rail is an arc-shaped surface that matches the waist of the rail.
[0010] Furthermore, a geotextile is pasted on the contact surface between the pallet and the rail.
[0011] Compared with the prior art, the advantages of the present invention are:
[0012] When constructing the integral roadbed of the subway shield section, one end of the direction adjustment rod is manually pressed against the waist of the rail, and the other end is inserted into the shield segment connecting bolt. When fine-tuning the track, a steel chisel is inserted into the circular hole in the middle of the hollow steel pipe and rotated back and forth to adjust the direction of the track. The above-mentioned direction adjustment rod for fine-tuning the track is easy to operate, can quickly adjust the direction of the track, and does not damage the rails; it avoids the quality risk of drilling holes on the shield segment to provide a point of action for the adjustment rod, which damages the shield segment.

[0017] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0018] like Figure 1 , Figure 2 , Figure 3As shown: a direction adjustment rod for fine adjustment of the track row in a shield section, comprising a tray 1 for supporting on the rail, a sleeve 2 for connecting with the connecting bolts of the shield segment and an adjusting rod 3 capable of adjusting the length; one end of the adjusting rod 3 is connected to the tray 1 through a first hinge joint 4, and the other end is connected to the sleeve 2 through a second hinge joint 5; the adjusting rod 3 is supported between the rail and the shield segment by the tray 1 and the sleeve 2, and the adjusting rod 3 applies a thrust to the rail with the connecting bolts of the shield segment as support, the rotating shafts of the first hinge joint 4 and the second hinge joint 5 are parallel to the length direction of the tunnel, the tray 1 and the sleeve 2 on the adjusting rod 3 can swing in the cross section of the tunnel, and as the adjusting rod 3 is extended or shortened, the angle between the tray 1 and the sleeve 2 and the adjusting rod 3 can be adjusted at any time.
