Problems solved by technology

[0005] Due to the large span and heavy hoisting weight of the hoisting gantry this time, although there are examples of Scheme 1 and Scheme 2, according to previous construction experience, Scheme 1 has large deformation, long hoisting time, and difficult positioning adjustment. The strength is good, but the unbalanced hoisting is prominent. Since the steel ball net frame of this project has been completed, the extension of the boom arm of the crane is restricted, resulting in insufficient extension of the arm of the large crane, so that both plan 1 and plan 2 are not applicable. For this reason, We propose a special construction technology for stacker-reclaimer mast installation

Embodiment 1

[0052] A special construction process for installing a stacker-reclaimer door frame, comprising the following steps:

[0053] Step 1. Crane station setting

[0054] Four truck cranes are used for hoisting, among which two 350t truck cranes are the main cranes. Bind it firmly with steel wire ropes. The lifting point of a 130t truck crane is set near the central column of the mast (point B, the center of the support of section A), and the lifting point of the other 80t truck crane is set on the side of the mast traveling mechanism ( Point C, which is the center of the support of section E of the gantry), each lifting point is fixed with a steel wire rope, and the A, B and C lifting points of the gantry are all made of 6*37+1-φ64mm steel wire ropes, and the A lifting point of the gantry Use two 6*37+1-φ64mm steel wire ropes to go around the single arm of the mast twice, and choose the appropriate wire rope to reduce the possibility of breakage during hoisting;

[0111] Inner Mongolia Jiutai New Material Co., Ltd. Coal Transportation Island Project with an annual output of 1 million tons of ethylene glycol

[0112] Project overview: Inner Mongolia Jiutai New Material Co., Ltd. has an annual output of 1 million tons of ethylene glycol project. The round coal yard of the coal handling island adopts the round stockyard stacker and reclaimer produced by Huadian Heavy Industry Co., Ltd., and its portal frame installation applies this construction craft. In this project, three circular coal yards with a diameter of Φ100m will be built, and the height of the coal retaining wall will be 16.5m. The coal storage capacity of a single circular coal yard is about 10×104t, and the total coal storage capacity of the three circular coal yards is about 30×104t, which can be used for about 20 days by the boiler and gasifier of this phase of the project. According to the requirements of the owner, incoming coal ...

Abstract

The invention discloses a special construction process for mounting a stacker-reclaimer gantry. The process comprises the following steps that first, the crane position is set, four auto cranes are adopted for hoisting, two 350t auto cranes serve as the main cranes, the hoisting points of the two 350t auto cranes are arranged at the centers of two arms at the top of the gantry up and down, the hoisting point of a 130t auto crane is arranged at the position, close to a central column, of the gantry, and the hoisting point of another 80t auto crane is arranged on the walking mechanism side of the gantry; second, a walking mechanism is hoisted; third, a gantry hoisting test is carried out, two cranes of the gantry are slowly hoisted by 0.5 m under the hoisting command at first, at the moment,the head of the gantry has already lifted, the 130t auto crane at the point B and the 80t auto crane at the point C are slightly lifted up to leave the ground to wait for 10 minutes, and the stressing conditions of all stressing points are checked; fourth, gantry rotating is conducted; and fifth, gantry lifting is made in place. According to the method, the structural design is reasonable, the gantry can be effectively mounted under the condition that a steel ball net rack is mounted, time is saved, and positioning and adjusting are facilitated.

Description

technical field [0001] The invention relates to the technical field of stacker-reclaimer door frame installation, in particular to a special construction process for stacker-reclaimer door frame installation. Background technique [0002] The gantry is an L-shaped irregular equipment with a span of 50 meters. It is divided into two box structures of 2800mm*1000mm. The horizontal projection length of the gantry is 50.82 meters. Separate supply, this equipment is supplied separately by the factory, assembled and installed on site, the assembly has been completed, and it has passed the acceptance test, meeting the conditions for lifting and hoisting. [0003] Option 1: In previous engineering examples, the weight and size of this project were consistent. Since the steel ball grid was not installed at that time, and the crane had a large operating space, the main lifting point was selected at the highest point of the mast, and two 260-ton cranes were used. Set up a 130t truck c...
