Problems solved by technology

[0003] Due to the short construction time and fast effect of track laying on the existing subway lines in my country, ordinary rail flat cars cannot meet the technical requirements for fast and convenient construction. Therefore, it is necessary to develop a set of detachable and convenient transportation rail flat cars for the current construction requirements of existing subway lines.

Embodiment 1

[0034] like Figure 7 As shown, a detachable convenient transport safety rail flat car described in this embodiment is mainly composed of a tripod, a wheel rail, a wheel axle, and an anti-slip safety pin, and the vehicle load is 1.5t. Each tripod is welded into a 390mm×1680mm frame by 4 longitudinal and 2 transverse channel steels with a thickness of 2mm. There is barbed wire on it and flat steel on the lower side. The whole vehicle platform is spliced ​​by three tripods. , The steel wire mesh on the upper part of the tripod is used to carry and transport heavy objects, and the channel steel and flat steel play the role of fixing and supporting the tripod. The wheel rail is made of φ100mm insulating nylon material, the gauge is 1435mm, and there are several φ6mm slot holes on the inside of the wheel rail, which are used for inserting the anti-rolling safety pin to fix the wheel rail. There are baffles welded on both sides of the axle, which are used to fix the relative positi...

Embodiment 2

[0040]Before the work, the anti-slip safety pin was in a mating state with the wheel rail through the fixing hole on the anti-slip car safety pin fixed sheet, and now the wheel rail could not rotate freely relative to the axle. When working, first pull out the anti-slip safety pin, then place a pair of wheel sets on the standard track respectively, and then keep them at a certain position front and rear, and then put the three tripods into it respectively to ensure that the tripods are connected to the hooks. The hand and the axle are reliably connected and placed in the block to ensure that the relative position of the tripod is fixed.

[0041] Then push the detachable convenient transport rail flat car to the loading position, and then use the anti-slip safety pin to insert the anti-slip car safety pin fixing piece and the slot hole of the wheel rail to fix the flat car position to prevent it from moving during the loading process. cause an accident. Load the required trans...

Abstract

The invention relates to the technical field of existing subway line track laying construction, and particularly relates to a detachable convenient-to-transport rail flat car and a using method. The rail flat car comprises a wheel set, a foot stool and an anti-slip safety pin structure, wherein the anti-slip safety pin structure comprises safety pin fixing pieces and an anti-slip safety pin, the anti-slip safety pin fixing pieces are arranged on the axle in a bilateral symmetry mode, fixing holes are formed in the anti-slip safety pin fixing pieces, and one ends of the anti-slip safety pins can penetrate through the fixing holes to be matched with the wheel rails so as to fix the relative positions of the wheel rails and the axle. Compared with the prior art, the combined structure is simple, feasible and easy to assemble and disassemble, and has the advantages that the foot stool and the wheel set axle can be separated, the whole vehicle is disassembled and assembled quickly, and transition transportation and quick operation are facilitated; the wheel set can be connected with different foot stools, so that different transportation effects are achieved, and the applicability is wider; and the anti-slip safety pin is additionally arranged, and the parking safety is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of track laying construction of existing subway lines, in particular to a detachable and convenient transport rail flat car and a use method thereof. Background technique [0002] During the track laying construction process of domestic subway existing lines, small and light transportation equipment is extremely important. The track flat car plays an important role in transporting construction materials and turnover construction equipment during the track laying construction of existing subway lines. It is an important small-scale transportation equipment in track laying construction. More construction time greatly improves construction efficiency. [0003] Due to the short construction time and quick effect of track laying on the existing subway lines in my country, ordinary track flat cars cannot meet the technical requirements for fast and convenient construction. Therefore, it is necessary to develop a ...
