Frame high-altitude piece mounting method of dry quenching lifter device

Abstract

The invention relates to a frame high-altitude piece mounting method of a dry quenching lifter device. The method comprises the following concrete steps of: lifting the two end beams of a frame piece component and a wheel group connected with the end beams onto a lifter track by use of a truck crane with tonnage of less than or equal to 300; lifting the two girders and accessories of the frame piece component to the position between the two end beams; assembling on a high-altitude construction platform so that the frame assembly work originally performed on the ground is finished at the high altitude; and in the frame assembly process on the high-altitude construction platform, firstly adjusting the space between the two end beams by use of an adjustable end beam fixing device, accuratelypositioning and mounting the two end beams on the lifter track by use of a wheel fixing device, and connecting the girders and the end beams to finish the mounting of the frame, wherein the accessories include a lower operation platform connected with the first girder and the second girder, and a walking first-level speed reducer arranged on the second girder. Compared with the traditional construction method, the method provided by the invention has the advantages of short construction period, low construction cost and the like, and is beneficial to construction.

Description

technical field [0001] The invention relates to a high-altitude segmental installation method for a car frame of a CDQ hoist device. Background technique [0002] The frame of CDQ lifting locomotive is composed of two end beams and two main beams. The traditional hoisting method is to assemble the frame on the ground and hoist it as a whole. After the frame is assembled, it weighs about 46 tons and needs to be hoisted to the hoist working plane at a height of 45.96 meters from the ground. According to the hoisting site conditions, 500 The truck crane of more than 10 tons can complete the hoisting task. At present, the number of truck cranes over 500 tons in China is relatively small, and leases must be booked in advance, and often affected by other factors, they cannot arrive on schedule, which in turn affects the overall construction period. Moreover, the 500-ton truck crane itself is heavy, difficult to transport, and expensive to enter the site. [0003] Just based on ...
