The side correspondence is provided with the axial junction plate in band radial concentric hole before and after left and right deck the inner, and hydraulic cylinder piston rod connector the inner is provided with axial screw, the outer end is provided with radially connecting hole, and the connecting rod left end is provided with the double-screw bolt section, right-hand member is provided with radially connecting hole; Hydraulic cylinder piston rod connector the inner is spirally connected with piston rod, the outer end is connected with left deck with bearing pin by the insulation sleeve of two ends band shoulder; The connecting rod left end is spirally connected with the piston rod bottom, right-hand member is connected with bearing pin with the insulation sleeve of right clamp seat by two ends band shoulder.
Connector outer end connecting hole and insulation sleeve are interference fit, and connecting rod right-hand member connecting hole and insulation sleeve are interference fit.
Rule comprises the chi chamber of fixedlying connected with the hydraulic cylinder piston rod connector and the moving scale chi that can slide therein, is connected with spring between at the bottom of moving scale chi and the chi chamber.
Hydraulic control pump is a manual pump.
The present invention is made up of mechanical part and hydraulic part, and wherein the mechanical part two ends are decks, and the centre is a hydraulic cylinder and connecting rod (steel pipe), and insulating effect is played with the transition of (nylon) insulation sleeve in deck and hydraulic cylinder and connecting rod (steel pipe) junction.Hydraulic part adopt well known to those skilled in the art manually or electric hydaulic control pump control hydraulic cylinder piston rod flexible.There is one dip stick-rule at the place at the hydraulic pressure cylinder head, can accurately measure the actual value of gauge.
The present invention can satisfy following line condition: maximum speed 350km/h Line for Passenger Transportation and maximum speed 250km/h Line for Passenger Transportation (taking into account shipping) and existing line are applicable to the gauge adjustment of quarrel and ballastless track.The applied code gauge is 1435mm, adjusting range is-20~+ 20mm.Test by EN 13146-5, two decks cut off insulaion resistance greater than 10k Ω, and satisfy the requirement of track circuit to its insulaion resistance.Concrete using method is:
(1) carry the spacing that the rule measurement is adjusted rail with space adjuster, according to iron mark gauge adjustment amount+8~-the 2mm requirement, draw the scope of adjusting rail;
(2) two snap joints of hydraulic cylinder oil pipe are connected the import and export of manual pump;
(3) as shown in Figure 1, space adjuster is stuck in two bursts of rail foot;
(4) come the control piston bar to push away, spur work by the manual pump handle;
(5) pressing about the handle makes the steady push-and-pull of piston rod, up to adjusting to the deck correct position, thoroughly unclamp the fastener that is adjusted each 1.4m about rail deck place;
(6) adjusting range of measuring according to rule, the pressing handle is until adjusting to the gauge normal place;
(7) after gauge is adjusted to standard, fastening all fasteners that unclamp;
(8), remove space adjuster by the anti-order that space adjuster is installed;
(9) forbidding thoroughly not unclamp fastener just brings into use the rail adjuster to adjust gauge;
(10) space adjuster must with the rail horizontal vertical, otherwise forbid to use;
The maintenance of space adjuster:
(1) before each the use, checks the whether leakage of oil of oil cylinder, oil pump;
(2) check whether connector, deck be unusual, loosening;
(3) check whether insulation meets the requirements;
(4) prevent to collide with.
The adjustment of this space adjuster fast, accurate positioning, maneuverability, easy and simple to handle, easy to carry, safe in utilization, be that the railway ew line is laid and the indispensable instrument of maintenance activity.
The specific embodiment
Steel rail space adjuster as shown in Figure 1, comprise right-hand member and right clamp seat 2 connecting rod 4 that insulation is connected, left end is connected with hydraulic cylinder 3, hydraulic cylinder 3 piston rod connectors 15 are connected with left deck 1 insulation, be equipped with on the piston rod connector 15 can be between piston rod connector 15 and hydraulic cylinder 3 cylinder caps the rule 10 of elastic telescopic, hydraulic cylinder 3 is connected with hydraulic control pump 17 by oil pipe 16, and hydraulic control pump 17 is connected with oil cylinder 14.
As Fig. 3, Fig. 6, shown in Figure 7, be used for the left deck 1, right clamp seat 2 of steel-fastening rail 25 inner before and after the side correspondences be provided with the axial junction plate 26 in band radial concentric hole.As shown in Figure 5, hydraulic cylinder 3 piston rod connectors 15 the inners are provided with axial screw 21, the outer end is provided with radially connecting hole 22.Connecting rod 4 left ends are provided with double-screw bolt section 18 as shown in Figure 4, right-hand member is provided with radially connecting hole 27.As Fig. 1, Fig. 2, shown in Figure 3, hydraulic cylinder 3 piston rod connectors 15 the inners are spirally connected with piston rod 8, the outer end is connected with left deck 1 with bearing pin 7 by the insulation sleeve 9 of two ends band shoulder, and piston rod connector 15 outer end connecting holes 22 are interference fit with insulation sleeve 9; The cottor pin 13 of bearing pin 7 outer ends is fixing by plain cushion 11 and hexagon slotted nut 12; Connecting rod 4 left ends are spirally connected with piston rod 3 bottoms, right-hand member is connected with bearing pin 7 with the insulation sleeve 9 of right clamp seat 1 by two ends band shoulder, and connecting rod 4 right-hand member connecting holes 22 are interference fit with insulation sleeve 9.
As shown in Figure 1 and Figure 2, chi chamber 19 outside buckles compress and are provided with a recessed pressing plate 5 of inboard band arc, and pressing plate 5 two ends are fixed on the hydraulic cylinder 3 piston rod connectors 15 by screw 6.As Fig. 8, shown in Figure 9, rule 10 comprises chi chamber 19 of fixedlying connected with hydraulic cylinder 3 piston rod connectors 15 and the moving scale chi 20 that can slide therein, and moving scale chi 20 and chi chamber are connected with spring 24 at 19 the end.Hydraulic control pump 17 is a manual pump, is provided with operating grip 23.
