Above-mentioned mounting structure and mode, in actual applications, have following shortcoming and defect:
1. due to the needs of actual installation, for adjusting surplus, the hole on backing plate is bar hole; Track bears vibratory force for a long time, and this power can be delivered to bolt by pressing plate, uses for a long time, bolt can produce loosening phenomenon, after bolt looseness, will in bar hole, produce displacement, cause pressing plate displacement, lose the restriction to track, like this, track also has lateral offset, the most direct consequence just cause wheel and track wiping rail, gnaw rail phenomenon, the wheel group of damaging weight-lifting equipment, the phenomenon that may occur jumping onto the tracks causes safety misadventure.
2. between pressing plate and backing plate, do not retrain and detent mechanism (effect), track bears axial power (when brake suddenly or startup), and track produces after longitudinal travel, and the pressing plate of close contact will be in free situation with it, there is the rotational action centered by bolt, can not push down track.
3. work as bolt looseness, need again when fastening, due to what adopt, be bolt, nut fixed form, so need two personnel's associated treatment: a people is in upper end, and a people, in bottom surface, has increased hoisting crane maintenance employee's inspection, maintenance workload, it two is service personnels of bottom surface, there is safety hazard in job position, there will be the situation of screw cap-falling while overhauling simultaneously, to ground staff, brings certain potential safety hazard.
Summary of the invention
The purpose of this utility model be to provide a kind of can not be shifted and rotation, fastening device for fixing running tracks safe, easy to adjust to overcome the deficiency of prior art.
The utility model is to realize the technical scheme that object adopts:
Device for fixing running tracks, comprises track and basis, between track and basis, has backing plate; The inclined-plane of pressing plate contacts and oppresses with the inclined-plane of track underbeam; It is characterized in that: on backing plate, have bar hole, have mounting hole in concrete foundation, bolt passes after bar hole and mounting hole, coordinate with nut and realize backing plate and basic fixing; On backing plate, have round screw, have circular hole on pressing plate, bolt, through circular hole and circle screw, is realized fixing.
Optimize: on described pressing plate, have projection, described round screw is positioned on projection; The both sides along centre-line of track vertical direction of pressing plate are provided with lower to limit, the lower both sides that encase projection along limit.
Good effect of the present utility model is: the utility model has adopted said structure, even the vibrated generation of bolt between pressing plate and backing plate is loosening, owing to being borehole structure, can not produce horizontal displacement yet, separately the bar hole of design has also met backing plate and basic surplus adjusting; Meanwhile, due to the design of screw, make fastening need one people of bolt get final product safe and efficient operation.In addition, projection and the lower rotation phenomenon that has overcome pressing plate along the design actv. on limit.

The specific embodiment
embodiment 1:
In the drawings, the 1st, track, the 2nd, basis, the 3rd, backing plate, the 4th, pressing plate, the 5th, inclined-plane, the 6th, inclined-plane, the 7th, bar hole, the 8th, mounting hole, the 9th, bolt, the 10th, nut, the 11st, circle screw, the 12nd, circular hole, the 13rd, bolt (thru-bolt), the 15th, projection, the 16th, lower to limit, the 18th, nut.
As shown in Figure 2, first by backing plate 3 placements and basic 2, regulate backing plate 3 positions, bar hole 7 on backing plate 3 is alignd with the mounting hole 8 on basis 2, bolt 9 is passed to bar hole 7 and mounting hole 8, nut 10 is tightened and realized the fixing of backing plate 3, track 1 is positioned over to backing plate 3 middle parts, the circular hole of pressing plate 4 12 is alignd with circle screw 11, the inclined-plane 6 of pressing plate 4 aligns with the inclined-plane 5 of track 1 underbeam, bolt 13 is aimed at and put into circular hole 12 and circle screw 11, tighten again, until pressing plate 4 is pressed abd fixed on backing plate 3, make the inclined-plane 6 of pressing plate 4 tightly push down the inclined-plane 5 of track 1, thereby realize the fixing of track 1.
In operational process, what directly bear vibration is inclined-plane 5 and inclined-plane 6, under the effect of vibration, thereby cause that bolt 13 is loosening, even if bolt 13 has certain becoming flexible, due to circular hole 12 and circle screw 11 little with the gap of bolt 13, so pressing plate 4 does not have horizontal displacement yet, all the time tightly push down track 1.In addition, due to not acting directly on backing plate on 3 of vibration, thereby bolt 9 can not become flexible, and in other words, just avoided the displacement phenomenon of the pressing plate 4 that original bar hole 7 causes.
Now, loosening bolt 13 be tightened, only be needed a people to operate rotating nut 10, lower end without another people coordinates, safer, and this advantage has benefited from the negative thread design of circle screw 11, and in the past, in basis 2, negative thread cannot be set, so cannot overcome this problem all the time.
When wheel suddenly stops or starts on track 1, track 1 is had to an axial power, this power can be transferred on the pressing plate 4 of contact with it, makes pressing plate 4 produce a larger deflecting torque.
In the present embodiment, what be arranged on pressing plate 4 both sides 16 coordinates with projection 15 along limit down, lower along limit 16 vertical direction along track 1 projection 15 bags are held together in inside.
Owing to thering is above-mentioned design, so pressing plate 4, under the restriction of projection 15, can not produce deflection, thereby avoided the possibility of the rotation displacement of pressing plate 4.
Embodiment 2:
As shown in Figure 6, when under the less working environment of some intensity, can not consider the situation of the axial force of track 1, under at this moment just can cancelling along limit 16 and design, pressing plate 4 and backing plate 3 plane contact of projection 15.
