Hoisting frame gantry device with telescopic cantilever

Abstract

The invention provides a hoisting frame gantry device with a telescopic cantilever. The hoisting frame gantry device comprises a hoisting frame, an adjusting mechanism, travelling mechanisms and a hoisting mechanism; the hoisting frame comprises vertical supporting legs, longitudinal bearing beams, transverse bearing beams and transverse connecting systems, the vertical supporting legs are arranged on the two sides of a pipe gallery mounting foundation pit, and the two ends of the transverse bearing beams are arranged exceeding the positions of the longitudinal bearing beams to form cantileverends; the hoisting mechanism is arranged at the bottom of one cantilever end of the transverse bearing beams, and the travelling mechanisms are arranged at the bottoms of the vertical supporting legs; the transverse connecting systems are arranged between two adjacent vertical supporting legs in the transverse position, the transverse connecting systems involves inclined struts and transverse struts, and each of the transverse struts and the inclined struts is formed by connecting two telescopic sleeves in a sleeved mode; and the adjusting mechanism comprises a hydraulic adjusting mechanism and a lead screw adjusting mechanism. The hoisting frame gantry device with the telescopic cantilever is simple in structure, high in safety coefficient, convenient to travel, wide in application rangeand suitable for pipe gallery construction with different section sizes, and project economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment for pipe gallery construction, and in particular relates to a cantilever telescopic hoisting frame gantry device. Background technique [0002] The hoisting device is an auxiliary device used to lift and move the components to the designated position during installation or maintenance. It has been widely used in the field of hoisting technology. The traditional hoisting structure has the disadvantages of heavy weight, high cost, and difficult construction. High safety risks and other defects, and does not have the conditions for streamlined construction, construction efficiency is low, in order to solve many shortcomings caused by the traditional hoisting structure in the construction process of the pipe gallery, it is particularly important to design a new type of hoisting frame. [0003] The patent application number 201721492513.4 provides a gantry crane for segmental hoisting of pip...

[0002] The hoisting device is an auxiliary device used to lift and move the components to the designated position during installation or maintenance. It has been widely used in the field of hoisting technology. The traditional hoisting structure has the disadvantages of heavy weight, high cost, and difficult construction. High safety risks and other defects, and does not have the conditions for streamlined construction, and the construction efficiency is low. In order to solve many shortcomings caused by the traditional hoisting structure in the construction process of the pipe gallery, it is particularly important to design a new type of hoisting frame

[0003] The patent application number 201721492513.4 provides a gantry crane for segmental hoisting of pipe gallery, including a set of main girder and cantilever beam, two sets of main vertical outriggers, a set of auxiliary vertical outriggers, a set of lifting crane and Its special spreader, two sets of the main vertical legs are supported in the installation pit of the pipe gallery, the lower surface of the main beam is connected with the upper surface of the main vertical legs, and the cantilever beam is the main The beam hangs out from the outer beam section of the main vertical outrigger, the lifting crane is installed on the main beam, and can walk along the main beam and the cantilever beam, and the upper part of the auxiliary vertical outrigger is connected to the cantilever beam. The cantilever beam is connected, the lower part is supported to the ground, and the pipe gallery section can be hoisted into the pipe gallery installation foundation pit, which greatly improves the lifting efficiency of the pipe gallery section, but there are problems of small application range and inconvenient movement
