Problems solved by technology

[0002] Due to the heavy weight of the crawler crane in the prior art, it is easy to cause damage to the ground. It is necessary to lay iron plates on the ground before construction to increase the bearing capacity of the ground, resulting in slow construction progress and increased construction costs.
In addition, the existing crawler cranes cannot fully utilize the construction site during the construction process, which affects the construction progress

Embodiment 1

[0011] In the crawler crane reinforcement construction method described in this embodiment, a subgrade box is laid on the crawler crane travel route. The main support beam is composed of three I-beams welded side by side. The two main support beams on both sides are connected by channel steel, and the center line of the channel steel is fixed by angle steel. The bottoms of the two ends of the main support beam are provided with Elevated steel plate.

[0012] In order to realize the long-distance forward operation of the crawler crane, the hot-rolled steel is used to butt-weld the roadbed box in the workshop, and then the roadbed box is laid in place by the steam crane at the construction site, and then the crawler crane is assembled by the steam crane, and the main engine of the crawler crane is installed first. , and then install the crawlers on both sides, then install the counterweight, then install the arm, and finally install the wire rope and the hook; after the completi...

Abstract

The invention provides a construction method for strengthening a track crane. The construction method comprises the following steps: firstly fitting up welding roadbed boxes in a workshop by using hot rolled section steel, then paving the roadbed boxes in place at a construction site through a vehicle crane, and finally assembling the track crane by using the vehicle crane; the step of paving the roadbed boxes comprises the following steps: firstly mounting a main engine of the track crane, then mounting tracks on two sides, mounting a balance weight block, mounting a rod, finally threading a steel rope and mounting a lifting hook. After the track crane is completed, the lifting operation can be officially started after an acceptance check is qualified, the track crane runs on the roadbed boxes during the lifting operation of the track crane, and the track crane can lift a roadbed box at the rear part of the track crane to the front part of the track crane, so that long-distance forward running operation is completed; according to the construction method for strengthening the track crane, the length of a roadbed box is at least larger than a distance between supports of a girder through paving the roadbed boxes, so that weight of the roadbed boxes and the weight of the track crane are applied to the supports of the girder; besides according to the track crane, the roadbed boxes can be paved on a running route of the track crane, so that the paving time is shortened, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to the field of crawler crane operations, in particular to a reinforcement construction method for crawler cranes. Background technique [0002] Due to the heavy weight of the crawler crane in the prior art, it is easy to cause damage to the ground. It is necessary to lay iron plates on the ground before construction to increase the bearing capacity of the ground, resulting in slow construction progress and increased construction costs. In addition, during the construction process of the existing crawler cranes, the construction site cannot be fully utilized, which affects the construction progress. Contents of the invention [0003] The object of the present invention is to provide a construction method that can directly transmit the load of the crawler crane to the beam-column frame of the bridge in order to solve the deficiencies of the above-mentioned technologies, avoid direct damage to the bridge deck, and reduce the scope...
