Problems solved by technology

Due to (1) the heavy workload of 3D solid modeling, in general, the modeling cycle of gantry cranes is 30 days; (2) there are many repetitive tasks in modeling, and every small change in structural parameters may The reconstruction of the entire model wastes a lot of time and energy; (3) The modeling software is highly professional and has high requirements for users, and it is difficult for ordinary users to master and use it proficiently in a short period of time, which will lead to the efficiency of safety assessment work not tall

Embodiment 1

[0028] Such as figure 1 As shown, the present invention provides a three-dimensional rapid modeling method for portal cranes, figure 1 It is the main program block diagram of the rapid modeling method, including the secondary development of Pro / ENGINEER5.0, using Pro / ENGINEER5.0 to establish and parameterize the 3D model of the portal crane, and using the secondary development program to modify the characteristic size value of the model template , generate a new model, and complete the 3D rapid modeling of the portal crane.

Embodiment 2

[0030] This embodiment is basically the same as Embodiment 1, and the special features are:

[0031] Such as figure 2 As shown, it is the secondary development subroutine block diagram of Pro / ENGINEER5.0. The secondary development of Pro / ENGINEER5.0 mainly includes writing menu resource files, parameterized dialog resource files, registration files, and main application program source files.

Embodiment 3

[0033] This embodiment is basically the same as embodiment two, and the special features are:

[0034] Such as image 3 As shown, it is to use Pro / ENGINEER5.0 to establish the 3D model model of the portal crane and parameterize the subprogram block diagram, including the structural division of the portal crane, the establishment of the 3D model diagram of each structure of the portal crane, and the 3D model of the portal crane Template parameterization, the specific operation steps are as follows:

[0035] Structural division of gantry crane: divide the structure of gantry crane into gantry, rotating column, turntable, man-shaped frame, lifting arm, large pull rod, elephant trunk;

[0036] Establish a three-dimensional model model of each structure of the gantry crane: such as Figures 5 to 11 As shown, according to the standard drawings, the length and width or inner and outer diameters of each structural section, overall length, wall thickness, internal rib spacing and thi...

Abstract

The invention relates to a rapid three-dimensional modeling method for a gantry crane and belongs to the field of mechanical design and manufacture. The rapid three-dimensional modeling method for the gantry crane is used for solving the problems in modeling of the large gantry crane in the field, and Pro / ENGINEER 5.0 secondary development and three-dimensional parameter modeling of the gantry crane are combined. The main work is secondary development of Pro / ENGINEER 5.0 and establishment of a three-dimensional parameter model template of the gantry crane. Through the combination of secondary development and modeling, a reference value can be rapidly modified through a parameter modification dialog box, so that a new three-dimensional model graph of the gantry crane is established.

Description

technical field [0001] The invention belongs to the field of mechanical design and manufacture, and in particular relates to a three-dimensional rapid modeling method for a portal crane. Background technique [0002] With the development of the economy, many large-scale engineering equipment are widely used. The issue of equipment security has also attracted more and more attention from the majority of business users and related units. As a large-scale lifting equipment, cranes undertake very heavy tasks in daily work. Usually the items that are hoisted are heavy and expensive items, so it is especially important to ensure the safety of the crane equipment. According to statistics, the number of deaths caused by crane accidents in my country accounts for about 15% of the total number of deaths in all industrial enterprises, and the number of casualties caused by crane accidents ranks first among all mechanical accident deaths. From the analysis of hoisting machinery accid...
