Example Embodiment

[0022] Example 1:

[0023] This embodiment is a double-body rail fixing device. The whole set of fixing devices are arranged on both sides of the upper flange rail 8 of the steel beam 7. It consists of a fixing base 1, an upper cover 2, a toothed backing plate 3, a bucket bolt 4, and a spring washer 5. , Nut 6. Composition.

[0024] Double-body reinforced structure, the fixed base 1 and the steel crane beam 7 are welded on all sides, and the fixed base 1 has grooves for welding with the car beam 7 around the fixed base 1 to strengthen the welding strength and force strength. The fixed base 1 has a central part Two T-shaped openings are used to hang bucket bolts 4, and the two sides of the bolts in the T-shaped opening of the fixed base are bucket-shaped (lower width and upper narrow) with a slope; the lower part of the bucket bolt 4 is fixed The contact part of the base 1 is bucket-shaped (wide at the bottom and narrow at the top) with a slope; the bucket bolt 4 is placed in the T...

Abstract

The invention belongs to the field of fixing devices, and discloses a dual-body track fixing device. The dual-body track fixing device comprises a fixing base; the middle part of the fixing base is provided with two T-shaped openings; each T-shaped opening is provided with a hopper-shaped bolt; the upper part of the fixing base is also connected with an upper cover; the middle part of the upper cover is provided with two bolt openings; the other ends of the hopper-shaped bolts pass through the bolt openings; the upper part of the upper cover is also provided with two tooth-shaped cushion plates. The invention aims to provide the dual-body track fixing device which is solid, durable, is unique in structure, is safe and convenient, is wide in application, and the overhauling expense is reduced greatly.

Description

technical field [0001] The invention relates to the field of fixing devices, in particular to a double-body rail fixing device. Background technique [0002] At present, with the rapid development of domestic modern industry, the lifting tonnage of lifting and transportation equipment and the lateral force generated by the four major coking vehicles in the working environment continue to increase. At the same time, there is a need for a more superior and stronger track fixing device; there are two traditional track fixing devices: one is the combination of the base and the upper cover, and the wedge-shaped adjustment plate is used to adjust the distance of the pressing track, and then the bolts are fixed. Track fixtures. The advantages of this fixing device: the precision of the track is adjusted through the wedge-shaped adjustment plate, the precision is high, the center of the bolt is closer to the track, and the force is large after the track is pressed. The disadvantag...
