Problems solved by technology

[0006] The size of the open box track beam is very large, generally longer than 20m, and the processing and heat treatment are difficult. In addition to the cost problem, the manufacture of the open box track beam is almost natural aging after welding, so its accuracy is very low; Rolled parts, because of their large length, their shape accuracy is not high

Embodiment 1

[0058] like Figure 1-2 shown in figure 1 In the structural schematic diagram of the suspended freight monorail three-way turnout, the fixed monorail open box track beam a is two I-shaped beams ( Figure 1-2Simplified in the above, the same below), the rotatable single-track open box-type track beam c is also two I-shaped beams arranged in parallel in space, which are fixed to each other; It consists of two I-shaped beams. The central two I-shaped beams of the three-track open box track beam e are arranged in parallel in space; the two I-shaped beams on both sides are arranged in parallel in space respectively; The angle between the I-shaped girders is exactly equal to the turnout angle. Two line-changing rails g are respectively placed on the upper surface of the lower bottom plate (the inner side of the vertical plate of the I-shaped beam) on the inner side of the I-shaped girder (the inner side of the I-shaped girder vertical plate) of the fixed monorail open box track be...

Embodiment 2

[0068] On the basis of Embodiment 1, the present invention also provides an installation process of a rail locker for a straight section of a rail of a suspended freight turnout, including an installation process and a working process.

[0069] 1. The installation process includes the following steps:

[0070] 1) Remove the two jaw set screws 44.

[0071] 2) Place the steel rail 4 in the proper position of the open box type track beam 1, and fasten the straight line section to be fixed with the open box type track beam 1.

[0072] 3) The movable straight section of the rail 4 and the open box-type track beam 1 are fixedly connected (removable) by a universal fixture, such as a screw pressing plate and the like.

[0073] 4) Start the hydraulic motor 2 in the reverse direction, and drive the left and right screw 12 to rotate, so that the locking claw A3 moves to the left, and the locking claw B5 moves to the right, so that the two claws are opened. When the distance between the t...

Abstract

The invention provides a rail locking device for a straight section of a rail for a suspended freight turnout and an installation process thereof. Both the tightening process and the unlocking process are completed automatically. The invention can realize the precise positioning and locking of the steel rail under the condition that the precision of the open box-type track beam and the steel rail is very low, can meet the frequent track change requirements of the suspended freight train turnout, and is safe, efficient and reliable.

Description

technical field [0001] The invention relates to a rail locker for a straight line section of a rail for a suspended freight turnout and an installation process thereof. Background technique [0002] The main feature of the suspended monorail transportation system is that the vehicle is suspended under the track beam through the running part of the upper part of the vehicle and placed in the open box-shaped track beam. The suspended monorail transports the ground traffic to the air, makes full use of the urban space, is not easy to derail, has strong climbing ability, small turning radius, low noise, low cost, little influence by weather, can be prefabricated, and has a short construction period and occupies a lot of land. Less, can be disassembled and reused and many other advantages. [0003] Suspended monorail transportation systems are generally used for passenger transportation, with small loads and high requirements for stability, so they are mostly rubber-wheeled syst...
