Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, the present invention discloses a crane heightening device 30 . First, let's introduce the structure of the following cranes. The crane includes a sea-side upper beam 10, a land-side upper beam 20, a sea-side column 40, a land-side column 50, and the like. The heightening device 30 of the present invention is arranged in the middle of the sea-side upper beam 10 , the land-side upper beam 20 , the sea-side upright 40 , and the land-side upright 50 . Specifically, the heightening device 30 is disposed below the sea-side upper beam 10 and the land-side upper beam 20 , and above the sea-side column 40 and the land-side column 50 .

[0027] Such as figure 2 As shown, the heightening device 30 of the present invention includes a sea side column heightening section 1, a land side column heighten...

Abstract

The invention discloses a crane heightening device and a crane heightening method. A crane comprises a large front beam, a large rear beam, an upper cross beam at the sea side, an upper cross beam at the land side, a vertical column at the sea side, a vertical column at the land side and the like; the heightening device comprises a heightening section of the vertical column at the sea side, a heightening section at the vertical column at the land side, a horizontal support rod, a door frame diagonal bracing, a door frame diagonal bracing at the sea side and a door frame diagonal bracing at the land side. The method comprises the following steps of: step 1, manufacturing the crane heightening device; step 2, dismounting the large front beam and the large rear beam of the crane; step 3, installing the heightening device on the ground below the upper cross beam at the sea side and the upper cross beam at the land side; step 4, resetting the large front beam and the large rear beam of the crane and a heightening device assembly; and step 5, connecting and installing the crane heightening device and the top ends of the vertical columns at the sea side and the land side of the crane. By adopting the technical scheme provided by the invention, the existing crane equipment can be utilized to the maximum, and the structure of the heightening device is simplified, so that the heightening method is convenient and rapid, and the cost is saved.

Description

technical field [0001] The invention relates to a device and a method for increasing the lifting height of a quayside container crane, more specifically, to a device and a method for increasing the height of a crane. Background technique [0002] With the increase in the capacity of transport ships, the stacking height of container ships continues to rise, and the requirements for the lifting height of container cranes on shore are also getting higher and higher. The old equipment in the original container terminal generally has a low lifting height and cannot meet the hoisting requirements. It is necessary to upgrade the container bridge crane. If the new bridge crane is redesigned and manufactured, it will not only take a long time, but also cost a lot. Based on the heightening transformation, it has become the first choice for all container terminals. The method of heightening and reconstruction of bridge cranes directly affects the cost of heightening and the period of ...
