Detailed Description
In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 1-6, a maintenance platform for mounting and dismounting a construction elevator comprises a main frame 1, a platform 2 and a fixed cross beam 4, wherein the main frame 1 is fixedly mounted on one side of the platform 2, and the fixed cross beam 4 is hinged on the main frame 1 and is detachably and fixedly connected with a cross rod of a guide rail frame;
the main frame 1 comprises a frame body 11, a front roller set 12 arranged on the inner side of the frame body 11, and a side roller set 13 arranged on the front side of the frame body 11, wherein the front roller set 12 and the side roller set 13 are symmetrically arranged on two sides of the frame body 11, the front roller set 12 comprises a first front roller 121 and a second front roller 122 which are arranged on two sides of a guide rail frame upright post and are opposite to each other, and the side roller set 13 comprises a first side roller 131 and a second side roller 132 which are vertically arranged and arranged on the guide rail frame upright post. The front roller set 12 and the side roller sets 13 are mounted on the frame body 11 through bolts.
Specifically, the number of the first positive rollers 121 and the number of the second positive rollers 122 on each side are two, that is, the four rollers on the same side, the two first positive rollers 121 and the two second positive rollers 122, are abutted against two opposite sides of one guide rail frame upright post, so that the guide rail frame can guide and prevent the guide rail frame from falling; meanwhile, the first side roller 131 and the second side roller 132 on each side are abutted against the guide frame upright post, so that the guide frame upright post can guide and prevent falling.
