Problems solved by technology

[0003] In addition, in view of the construction characteristics of high-speed railway sound barriers generally in the late stage of the project, and considering the mutual intersection and interference with other construction processes, the only choice is to install the sound barrier in the gap between rail laying, electrification construction and overall locomotive commissioning , the construction tasks are heavy and the construction period is tight, so high-efficiency mechanized equipment must be used, and the invention of a mechanized construction equipment has become a top priority for the modern construction requirements of the sound barrier

Embodiment Construction

[0021] The present invention will be described in detail with reference to the drawings.

[0022] Such as figure 1 As shown, the universal sound barrier crane is composed of a base and an upper crane, which includes: 1. hook assembly, 2. telescopic boom (two sections), 3. basic boom, 4. telescopic cylinder (built-in), 5. amplitude indication Device, 6. Luffing cylinder, 7. Lifting mechanism, 8. Turntable, 9. Control mechanism, 10. Slewing base, 11. Flange, 12. General railway flat car, 13. Railway rail.

[0023] The upper crane is connected with a general railway flatbed car or a comprehensive maintenance vehicle through a flange, so that the universal sound barrier crane can complete the all-round hoisting operation of the sound barrier along the rail direction.

[0024] By replacing two different lifting fixtures at the end of the universal sound barrier crane, the lifting work of different component units of the sound barrier can be completed, such as figure 2 , As shown in 3.

Abstract

The invention relates to a universal crane for the construction process of a high-speed railway sound barrier, belonging to the field of construction equipment. The universal crane is a flat truck type mobile universal sound barrier crane which comprises a base and a crane independently working on the base, wherein the base is a railway flat truck or an engineering comprehensive maintenance truck, and the crane and the railway flat truck or the engineering comprehensive maintenance truck are respectively provided with an independent dynamic system. The universal sound barrier crane can carry out construction operations on vertical sound barriers, eave-folded sound barriers and totally enclosed sound barriers under any condition, the maximum hoisting load is 0.5 ton, both the maximum length and the maximum height of an extended arm are 11 meters, and the universal sound barrier crane can be used for hoisting and installing I-shaped steel upright columns and sound barrier unit boards by replacing different hoisting jigs. For intermittent operation situations of the sound barrier, the universal sound barrier crane can be designed into a retractable mode, so that the volume can be reduced, thereby facilitating transportation and use.

Description

Technical field [0001] The invention relates to a construction hoisting machine used in the construction of a high-speed railway sound barrier, belonging to the field of construction equipment. Background technique [0002] my country's high-speed railway and other transportation infrastructure construction are in a period of rapid development, but the construction equipment of sound barriers is obviously lagging behind the supporting construction equipment of high-speed railways. During the construction of sound barriers, construction sites with construction operations are generally used The sound barrier components are hoisted by car cranes, while for some special construction sites with no operating space, the sound barrier components are manually transported and installed, which causes a lot of waste of human resources and is difficult to construct in some construction sites. There are potential safety hazards in the area. [0003] In addition, in view of the construction charac...
