Embodiment Construction

[0029] Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail:

[0030] Take the vehicle-mounted drilling rig mast frame with a length of 12m as an example. The vehicle-mounted drilling rig mast frame includes frame 1. The cross section of frame 1 is a groove structure. The vertical edge of the groove type of the frame is welded with guide rail components. The fixed plate 3 on the vertical side of the type is connected with several connecting plates 4 by bolts on the fixed plate 3 on each side, and the guide rail 5 is arranged on the connecting plate 4, such as figure 1 , 2 shown.

[0031] The design of the mast frame of the 12m vehicle-mounted drilling rig requires that the straightness be within 3mm. The assembly method is described in detail below, including the following steps:

[0032] ①Welding frame 1: Frame 1 is a large-scale riveted weldment. When assembling and welding frame 1, ensure that the distance be...

Abstract

The invention discloses a method for assembling a large long guide rail assembly with guaranteed straightness. An assembly sequence of an existing method is changed by the method. The method includes controlling a tool and assembling guide rails with the requirement on guaranteeing the straightness; integrally welding the assembled guide rails with the excellent straightness with a frame to obtain a final product. The method has the advantages that a guide rail part of the product manufactured by the method is excellent in straightness, a workpiece can assuredly freely slide on the guide rails, and the safety performance is greatly improved when a truck-mounted drilling rig works; the method is economical, practical and simple, operation is easy, and the production efficiency is obviously improved; the tool can be reused, and accordingly the production cost is lowered.

Description

technical field [0001] The invention relates to a method for processing and assembling mechanical components, in particular to a method for assembling large-scale long guide rail components. Background technique [0002] Vehicle-mounted drilling rigs are required in the construction of ground gas drainage in coal mining areas, shallow oil, hydrological water wells and geological exploration, and mine rescue. The drilling frame of the vehicle-mounted drilling rig is generally a telescopic mast. When the telescopic mast is extended, the height can reach more than 20 meters, and when retracted, the length is more than 10 meters. The telescopic mast includes a telescopic rod and a mast frame that provides a track for the telescopic rod. The power head of the drilling rig moves on the telescopic rod, and at the same time the telescopic rod moves along the guide rail of the mast frame. Therefore, there must be a tight gap between the telescopic rod and the guide rail of the mast ...
