Mast crane applied to river network area

Abstract

The invention discloses a mast crane applied to the river network area. The mast crane comprises a body. The body comprises a rotation base, a rotation platform, a main mast and a lifting mast. The rotation base is fixed, and the main mast and the lifting mast can synchronously rotate with the rotation platform through a rotation driving vertical motor. A lifting winch and a variable amplitude winch are arranged in a layering manner, a variable amplitude steel wire rope penetrates the top of the main mast from back to front, a lifting steel wire rope directly penetrates the bottom of the main mast, and the situation that the steel wire ropes interfere with each other can be effectively prevented. In addition, a winch system is arranged at the rear end of the rotation platform, and the balance weight balancing function can be achieved. The main mast and the rotation platform are connected through bolts or pins. When the main mast is integrally assembled, an installing support plays a supporting role, the main mast is pulled and erected through a vertical rod, and therefore the main mast can be rapidly assembled.

Description

【Technical field】 [0001] The invention relates to a crane, in particular to a mast crane used in river network areas. 【Background technique】 [0002] There are many mountainous rivers in Hubei, Jiangxi and other provinces, so many of these high-voltage transmission line towers must be built in mountainous areas, rivers and other areas. It is difficult for general large cranes to enter these places, which also makes it difficult to transport tower materials, so it is difficult to build towers and other problems. In view of the above problems, a kind of crane is often used in construction, which has poor flexibility, cumbersome installation, cannot be rotated and hoisted at 360 degrees, and cannot adapt to the self-generating hoisting work of the crane under the condition of no power supply. 【Content of invention】 [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a mast crane applied in the river network area, which can not onl...
