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

[0046] 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 1-2 Simplified 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 monorai...

Embodiment 2

[0058] On the basis of Embodiment 1, the present invention also provides a working process of a suspension-type freight turnout rail follow-up rail locker, comprising the following steps:

[0059] Step 1. When it is necessary to change the line of the turnout rail, reversely start the hydraulic motor 12, and the output shaft of the hydraulic motor 12 rotates in the reverse direction, driving the transmission shaft 11, the small bevel gear 10, the large bevel gear 7, and the shaft screw 9 to rotate in reverse together ; Nut 18 and push rod 17 move downward in a straight line due to being restricted by the blocking pin shaft 24 and guide sleeve 19, and the lifting slide table 4 and locking plate 5 move downward together with the push rod 17 under the action of their own weight. Lock loose. The line-changing rail 2 can be changed as required. During the line-changing process of the line-changing rail 2, all components of the follow-up rail locking device (except the open box-shap...

Abstract

The invention provides a suspension type freight turnout steel rail follow-up rail locking device and a working process thereof. The device comprises four guide rods fixedly connected with a steel rail, a lifting sliding table arranged on the guide rods in a sleeving mode, a locking plate, a lead screw nut pushing the lifting sliding table and the locking plate to move up and down, and a driving system. Under the condition that the precision of the open box-type track beam and the precision of the line-changing steel rail are very low, follow-up locking of the line-changing steel rail can be achieved, the requirement for frequent track 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 suspension type freight turnout rail follow-up rail locker and its working process. 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 suspended freight monorail transportation system ...
