Problems solved by technology

The invention has the advantages of anti-loosening, strong anchoring, simple structure, easy installation, large adjustment amount, low cost, etc., and effectively solves the possible hazards to the operation of the maglev train such as the loosening of the fastener bolts and the relatively serious problems of the track beam foundation. When it sags or arches greatly, it is difficult to achieve negative adjustment and positive adjustment with a large amount of height adjustment

Embodiment 1

[0031] An anti-loosening strong anchoring large height adjustment fastener for the track row of medium and low speed maglev trains, which is composed of a bolt square head anchor structure, a bottom plate anchor structure, a rubber pad group, a height adjustment group, and a lock nut group; the bolt square head anchor Structure, floor anchoring structure, rubber pad group, height adjustment group, and lock nut group are arranged sequentially from bottom to top to form the main body of the fastener.

[0032] The bolt square head anchoring structure is composed of a square head of a square head bolt 1 and four bottom steel bars 9 arranged vertically and horizontally on it, and is anchored in grouting material or cement after the rail platform is poured. Such as figure 1 , figure 2 , image 3 , Figure 5 shown. The grouting material or cement is injected into a rectangular rail platform. The rail bearing platform is a rectangular or square platform made of grouting material...

Embodiment 2

[0047] Others are with embodiment 1. The difference is that the fastener is a double anchor lag bolt fastener. The bolt square head anchoring structure is composed of the square heads of two square head bolts 1 and six bottom steel bars 9 arranged vertically and horizontally on them; the height adjustment group 5 is a set of rubber and plastic plates with two slots 5A , or nylon plate, or other steel plates and other materials, which are composed of one or two or more plates with a thickness of 0.1mm, 0.2mm, 0.5mm, 1mm, 2mm, 5mm, 10mm, or 20mm. After the total thickness of 20mm, its shape is E-type.

Embodiment 3

[0049] Others are with embodiment 1. The difference is that the fastener is a four-anchor lag bolt fastener. The bolt square head anchoring structure is composed of the square heads of four square head bolts 1 and eight underlying steel bars 9 vertically and horizontally arranged on them; the height adjustment group 5 is a set of rubber and plastic plates with two slots 5A , or nylon plate, or other steel plates and other materials, which are composed of one or two or more plates with a thickness of 0.1mm, 0.2mm, 0.5mm, 1mm, 2mm, 5mm, 10mm, or 20mm. After the total thickness of 20mm, its shape is E-type.

Abstract

The invention relates to a fastener for assembly of track panels, in particular to an anti-loosing, double-layer and strong-anchoring fastener for assembly of track panels of a low- and medium-speed maglev track, which is provided with a fastening nut, a lock nut, a heavy spring and a rubber gasket for joint action. The anti-loosing, double-layer and strong-anchoring fastener is capable of meeting various requirements of track sleepers on one to four strong-anchoring bolts in assembly and design, the track is more stable and safer, and the height of the fastener can be adjusted from -20mm to +60mm. The anti-loosing strong-anchoring fastener has the advantages of simple structure, easiness in assembly, high adjusting precision, high height adjustment and the like, and the problems of operational hazards and the like of a maglev train due to loosing of the fasteners and the like can be solved effectively.

Description

technical field [0001] The invention relates to an anti-loosening strong anchorage fastener with a large amount of height adjustment, in particular to an anti-loosening and double-layer fastening nut, a lock nut, a heavy spring and a rubber pad for the installation of the track rail row of a medium-low speed maglev train. Strong anchor fasteners improve track safety. Background technique [0002] The medium and low speed maglev train rail transit system refers to an environment-friendly transportation tool that runs at a speed of 80-150 kilometers per hour, has a small turning radius, strong climbing ability, low noise, and no pollution. It is being rapidly developed and popularized for its excellent comprehensive performance. . The track rails of medium and low-speed maglev trains are about 2m to 13m long and weigh about 1 to 6 tons. Such weight rails require that they be installed on reinforced concrete beams with a height of three to ten meters, and the installation accu...
