Floating bridge type pedestal of semi-mobile crushing station for mining, and its application

Abstract

The invention provides a floating bridge type pedestal of a semi-mobile crushing station for mining, and its application. The semi-mobile crushing station comprises a plurality of main columns for supporting the body of the semi-mobile crushing station, and a discharging platform for supporting bottoms of the main columns. The floating bridge type pedestal comprises: two main floating bridges, wherein the main columns corresponding to the two main floating bridges support the bottom of the discharging platform, and the inner side of each of the main floating bridges is symmetrically provided with at least one cantilevers; and supporting structures which are respectively detachably assembled under the each of the cantilevers at the inner side of each of the main floating bridges, and support the cantilevers. The cantilever floating bridge type pedestal adopting above supporting structures makes the supporting structures directly support just under steel structure auxiliary columns, so bearing force of the auxiliary columns is dispersed, the bearing force of the main columns, the auxiliary columns and the cantilevers is uniform, and the fatigue deformation of the cantilevers is prevented; and simultaneously weights of the main floating bridges are substantially reduced, and the supporting structures can be demounted when the crushing station is moved, so the pedestal of the invention can be applied to large crawler belt transport vehicles.

Description

technical field [0001] The invention relates to mining equipment, in particular to a pontoon-type base of a semi-mobile crushing station for mining with stable structure and convenient relocation and its application. Background technique [0002] At present, in the known technology, the pontoon-type base of the semi-mobile crushing plant with a processing capacity greater than 1500t / h is basically the following two types: one is the integral pontoon-type , to leave a moving space for the large-load crawler transport vehicle, and its upper part should be designed as a cantilever beam support structure. Due to the self-weight of the equipment and the crusher will generate large vibration during work, in order to avoid fatigue deformation at the joint of the cantilever support structure , it is necessary to strengthen the overall structure of the pontoon base, which leads to an increase in the overall weight of the base, which brings difficulties to the transportation of the po...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, to provide a pontoon-type base of a semi-mobile crushing station for mining, to solve the problem that the cantilever support connection of the existing pontoon-type base is prone to stress deformation and cannot be used due to structural limitations. The problem of one-time relocation of the load-carrying crawler transport vehicle finally reduces the operating cost and improves the operation rate of the stope
