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] Such as Figure 1-2 shown in figure 1 In the structural schematic diagram of the suspended freight monorail three-opening turnout, the fixed monorail open box track beam a is two I-shaped beams ( Figure 1-2Simplified in , the same below), the rotatable single-track open box-shaped track beam c is also two I-shaped beams arranged in parallel in space; the three-track open box-shaped track beam e is composed of six mutually fixed The two I-shaped girders in the center of the three-track open box track beam e are arranged in parallel in space; the two I-shaped girders on both sides are respectively arranged in parallel in space; the central I-shaped girder and the two sides The included angle between the I-shaped girders is just equal to the line change angle of the turnout. The two change-line rails g are respectively placed on the upper surface of the lower bottom plate inside the I-shaped girder (inside the vertical plate of the I-shaped girder) of the fixed monorail...

Embodiment 2

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

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

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

[0071] 2) The rail 4 is placed at a suitable position of the open box-shaped track beam 1, and the straight line section to be fixed of the steel rail 4 is fixedly connected with the open box-shaped track beam 1.

[0072] 3) The movable straight section of the rail 4 is connected (detachable) to the open box-shaped track beam 1 through a universal clamp, such as a screw clamp and the like.

[0073] 4) Reversely start the hydraulic motor 2 to 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 ...

Abstract

The invention provides a suspension freight turnout steel rail linear segment rail locking device and a mounting process thereof.The device comprises two clamping jaws which are provided with hook heads and are symmetrically arranged, the two clamping jaws are driven by a hydraulic motor through a left-handed lead screw and a right-handed lead screw to move, and the locking process and the unlocking process are both automatically completed. Under the condition that the precision of the open box type track beam and the precision of the steel rail are very low, accurate positioning and locking of the steel rail are achieved, the requirement for frequent rail changing of a suspension type freight train turnout can be met, and safety, high efficiency and reliability are achieved.

Description

technical field [0001] The invention relates to a rail locking device for a straight line section of a steel rail for a suspension freight turnout and an installation process thereof. Background technique [0002] The main feature of the suspended monorail transportation system is that the running part on the upper part of the vehicle is placed in the open box-shaped track beam, and the vehicle is suspended to run under the track beam. The suspended monorail transport moves the ground traffic to the air, making full use of the urban space. It is not easy to derail, strong climbing ability, small turning radius, low noise, low cost, less affected by the weather, prefabricated and short construction period, occupying an area Less, detachable and reusable and many other advantages. [0003] The suspended monorail transportation system is generally used for passenger transportation, with small load and high stability requirements, so it is mostly made of rubber tires; while the...
