Embodiment 1

[0045] A lifting mechanism of this embodiment, such as figure 2 Shown, comprise the pulley group that fixed pulley 5 and movable pulley 6 form, also comprise the pull-up mechanism 1 of low position and the auxiliary hanger 4 of high position; The lifting mechanism 1 passes through the pulley block chute by the traction line to drive the driving pulley 6 to lift the weight and rise. The hoisting mechanism of this embodiment is a hoisting mechanism that does not require the use of a crane. When this mechanism is installed without the need for a crane, it is only necessary to fix the lifting mechanism 1 at a low position and the auxiliary hanger 4 at a high position. Realize the purpose of lifting heavy objects such as large steel structures and reinforced concrete components, with strong mobility and low requirements for the installation environment on the processing site.

Embodiment 2

[0047] A lifting mechanism of this embodiment, the specific structure is basically the same as that of Embodiment 1, and the improvement is that the number of fixed pulleys 5 and movable pulleys 6 in the pulley block is the same, which can be three, and correspond to each other, and can be combined. The shape and weight of large structural parts are configured accordingly, and the characteristics of large structural parts, good symmetry, and easy configuration of the position of the pulley blocks can achieve mutual synergistic technical effects. Can also include guide pulley 3, the traction line of pulling mechanism 1 passes through guide pulley 3 chute first, and then works on the pulley block, can coordinate the position of pulley block and pulling mechanism according to the situation on the spot, further improves the flexibility of lifting mechanism and Versatility.

Embodiment 3

[0049] A lifting mechanism of this embodiment and a lifting system for large structural parts based on the mechanism, such as figure 1 , 3 As shown, it is applied to the 4# blast furnace project of a steel plant, the steel corridor is 30t, the span is 40m, and the lifting height is 15m, such as Figure 5 , 6 As shown, 4 sets of this lifting mechanism are adopted, and the basic structure of the lifting mechanism is the same as that of embodiment 2. The improvement is that the lifting mechanism 1 is a winch, so as to improve the lifting height of the whole mechanism to the heavy object, which can be any height in theory. Moreover, the maneuverability is strong; the guide pulley 3 is fixed in the horizontal direction of the hoist, directly below the pulley block, and the force direction of the traction line is turned to be vertically downward, and the pulley block is pulled to avoid oblique pulling and shaking, and achieve a smooth lifting effect ; Realize the maximization of t...

Abstract

The invention discloses a lifting mechanism and a lifting system based on the lifting mechanism for a large structural part, and belongs to the technical field of lifting devices. The lifting mechanism comprises a pulley block which is composed of a fixed pulley and a movable pulley, and further comprises a low pull-up mechanism and a high auxiliary hanging bracket; the pulley block is fixed onto the auxiliary hanging bracket through a rotary shaft of the fixed pulley; and the pull-up mechanism passes through a slide slot of the pulley block through a pull wire to drive the movable pulley to lift a heavy object to ascend. In addition to the lifting mechanism, the lifting system for the large structural part further comprises pedestals which are symmetrically arranged left and right and are fixedly arranged at the two sides of the large structural part, and structural stand columns which is fixedly arranged on the pedestals perpendicularly. The lifting mechanism does not need a crane; in case of not needing to adopt the crane, the pull-up mechanism is fixedly arranged on a low position and the auxiliary hanging bracket is fixedly arranged on a high position by mounting the lifting mechanism, so that a large steel structure and a reinforced concrete component can be lifted, and therefore, maneuverability is strong and requirements on mounting environment of a processing site are low.

Description

technical field [0001] The invention belongs to the technical field of lifting devices for large structural parts, and in particular relates to a lifting mechanism and a lifting system for large structural parts based on the mechanism. Background technique [0002] The weight of large steel structures and reinforced concrete components is often dozens of tons or hundreds of tons. In traditional hoisting construction, the main lifting equipment used is cranes. Various cranes include truck cranes, crawler cranes, tower cranes, floating cranes, driving cranes, etc. . It is usually hoisted by one crane or multiple cranes. [0003] However, under some special difficult conditions, such as working on water, the current construction schemes of large-span arch bridges on water include: cable hoisting schemes, bracket schemes, and swivel construction schemes. The main questions are as follows: [0004] 1. For the cable hoisting scheme, it is necessary to set up multiple taller tow...
