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
The present invention relates to a kind of crawler crane field of operation, particularly a kind of crawler crane reinforced construction method.
Background technology
Because its weight is comparatively large during crawler crane construction of the prior art, easily damage ground, need to carry out iron plate laying to ground before construction, to increase load supporting ability of ground, cause construction speed slow, construction cost increases.Full use cannot be carried out to construction plant in existing crawler crane work progress in addition, affect construction speed.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and a kind of beam column frame that crawler crane load can be directly delivered to bridge is provided, avoiding bridge floor to be subject to direct destruction, reduce the construction method of Deck Consolidation job area.
In order to achieve the above object, the crawler crane reinforced construction method designed by the present invention, crawler crane track route lays subgrade case, and the distance between length at least two construction plant crossbeams of described subgrade case or large beam support is equal.
Described subgrade case is made up of the main brace summer of both sides, and main brace summer is welded side by side by three i iron, and two main brace summers of both sides are connected by channel-section steel, and the centerline of channel-section steel is fixed by angle steel again.
The bottom at described main brace summer two ends is provided with padded steel plate.
In order to realize the long distance advance operation of crawler crane, first use hot-rolled steel section welding subgrade case in workshop, then hung by vapour at the construction field (site) and subgrade case laying is put in place, then vapour is used to hang assembling crawler crane, first crawler crane main frame is installed, deals with problems arising from an accident and both sides crawler belt is installed, then carry out the installation of counterweight, then carry out the installation of penholder, finally carry out the installation of cable wire threading and suspension hook; After crawler crane completes, formally can start lifting operation through checking and accepting, in crawler crane lifting operation, crawler crane is walked on subgrade case, and the subgrade case at its rear portion can be lifted into front portion by crawler crane, thus completes long distance advance operation.
The crawler crane reinforced construction method that the present invention obtains, it is by the laying of subgrade case, and the length of subgrade case equals the distance between at least two construction plant crossbeams or large beam support, the weight of subgrade case and crawler crane is made all to be applied on crossbeam or large beam support, crane can lay subgrade case on self passing line, can effectively reduce the laying time, construction speed is accelerated.Devise the simple subgrade case structure of structure simultaneously, only need to form main brace summer by simple three i iron as main material, then by channel-section steel and angle steel permanent position, subgrade case processing can be completed, reduce further construction cost and time.
Detailed description of the invention
The present invention is further described by the following embodiment.
Embodiment 1.
The crawler crane reinforced construction method that the present embodiment describes, crawler crane track route lays subgrade case, length and at least two construction plant crossbeams or the large beam support of described subgrade case, described subgrade case is made up of the main brace summer of both sides, main brace summer is welded side by side by three i iron, two main brace summers of both sides are connected by channel-section steel, and the centerline of channel-section steel is fixed by angle steel again, and the bottom at described main brace summer two ends is provided with padded steel plate.
In order to realize the long distance advance operation of crawler crane, first use hot-rolled steel section welding subgrade case in workshop, then hung by vapour at the construction field (site) and subgrade case laying is put in place, then vapour is used to hang assembling crawler crane, first crawler crane main frame is installed, then both sides crawler belt is installed, then carries out the installation of counterweight, then carry out the installation of armed lever, finally carry out the installation of cable wire threading and suspension hook; After crawler crane completes, formally can start lifting operation through checking and accepting, in crawler crane lifting operation, crawler crane is walked on subgrade case, and the subgrade case 1 at its rear portion can be lifted into front portion by crawler crane, thus completes long distance advance operation.
