Embodiment Construction

[0015] The present invention will be further explained in detail below in conjunction with the accompanying drawings.

[0016] In order to provide accurate basic data of crane jib torsion, provide original reference data for crane jib design, and ensure safe operation of the crane, the invention provides a jib torsion test device. The jib torsion test device of the present invention uses a large-tonnage jib as a force carrier, a small-tonnage jib as a test jib, and generates torsional torque through symmetrically installed loading cylinders, thereby realizing multiple tests of jib torsion.

[0017] figure 1 , figure 2 They are respectively a structural schematic diagram and a partially enlarged schematic diagram of the boom torsion test device of the present invention. As shown in the figure, the boom torsion test device of the present invention includes a boom 1, a first fixed tool 2, a test boom 3, a second fixed tool 4, a loading cylinder 5, a loading plate 6, a rotating...

Abstract

The invention provides a cantilever crane torsion test device, which comprises a large cantilever crane, a test cantilever crane, a first fixing tool, a second fixing tool, two loading oil cylinders, a loading plate, a rotation shaft and a rotary supporting bracket, wherein the test cantilever crane is smaller than the large cantilever crane, one end of the test cantilever crane is fixed on the large cantilever crane through the first fixing tool, and the other end is fixedly connected with the loading plate; one end of the rotation shaft passes through a central through hole of the loading plate, and the other end is connected on the rotation supporting bracket; the rotation bracket is fixed on the lower part of the large cantilever crane; and the two loading oil cylinders are symmetrically connected on two ends of the loading plate, and the loading oil cylinder is fixed on the upper part of the large cantilever crane through the second fixing tool. The cantilever crane torsion test device has simple structure and convenient operation, and can effectively perform the torsion deformation test of the cantilever crane.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a jib torsion test device. Background technique [0002] In a crawler crane, the front end of the crane has a jib frame for supporting and lifting the object to be hoisted, and the rear end has a counterweight for weight balance with the front end jib frame and the object to be hoisted. In the specific operation of the crane, due to the excessive load, the boom often suffers from torsion and deformation. This directly affects the performance and service life of the whole crane, and will cause certain safety problems. Therefore, there is an urgent need for a device that can measure the torsional deformation parameters of the jib, so as to improve the crane accordingly and limit the load accordingly, so as to ensure the safety of the crane operation process. Contents of the invention [0003] The main purpose of the present invention is to provide a jib torsion test device, whic...
