Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] combine figure 1 and figure 2 As shown, a crane for installing bridge shutters includes a main structure frame, hoist crane guide beam 2, front hoist crane 4 and rear hoist crane 3. The main structural frame has two front supporting columns 5 and two rear supporting columns 1, and the main structural frame forms the main stressed structure of the crane to ensure the stability of the shutter installation. The gourd hanging guide beam 2 is installed in the middle of the upper end surface of the main structure frame, and the front end of the gourd hanging guide beam 2 extends out of the main structure frame, so that the movable range of the hoisting shutter is further extended outward. The front hoist crane 4 and the rear hoist crane 3 are successively installed on the hoist crane guide beam 2, and the coordinated operation of ...

Abstract

The invention relates to a hoist for mounting a bridge shield plate, which comprises a main structure frame, a cucurbit hoist guide beam, a front cucurbit hoist and a rear cucurbit hoist, wherein the main structure frame is provided with a front support vertical column and a rear support vertical column; the cucurbit hoist guide beam is installed in the middle of the upper end surface of the main structure frame, and the front end of the cucurbit hoist guide beam extends out of the main structure frame; the front cucurbit hoist and the rear cucurbit hoist are sequentially installed on the cucurbit hoist guide beam; a weight counter is installed on the rear support vertical column, a guide wheel is installed on the front support vertical column, and a fixed wheel is installed on the rear support vertical column. The invention has simple structure, low cost and convenient maintenance. The installation and construction processes of a passenger transport special line bridge shield plate are tightly combined; and by a scene test, the hoist can meet the installation precision requirement on the shield plate, and has simple and convenient operation without influencing the development of other construction operations.

Description

technical field [0001] The invention belongs to an installation device for a bridge shutter of a passenger dedicated line, in particular to a crane used for installing a bridge shutter. Background technique [0002] The mass of the bridge deck shutters of the passenger dedicated line is about 500kg, and its installation work cannot be carried out by manpower alone. However, since the shutters are installed continuously on the bridge deck, continuous construction is required. If ordinary truck cranes are used for installation, on the one hand, it is difficult to control the installation accuracy, and on the other hand, ordinary truck cranes occupy a large area, which will inevitably affect other construction operations. development, thereby affecting the construction progress. The patent number is 200720191945, and the invention patent titled "simple track-type cantilever crane" discloses a crane technical solution: it includes a cantilever boom support, a cantilever boom, a...
