Problems solved by technology

[0004] The installation method of the above-mentioned slewing mechanism can effectively install and fix the slewing mechanism, but the machining accuracy of the corresponding mounting bolt holes of the slewing upper support frame is high and the processing procedure is complicated
Moreover, the structure of the slewing support frame is compact. When the slewing mechanism is assembled, due to the structural limitations of the slewing support frame, it is difficult to assemble the bolt group, which is time-consuming and labor-intensive.
Bolts are prone to missing tightening or insufficient tightening. During use, the flange is mainly pressed by the bolt group to increase the friction between the flange and the slewing support frame to resist the torque of the slewing mechanism. The bolts are tightened too loosely during installation. It will cause the bolt group to loosen during use, making the installation of the slewing mechanism invalid, and there are potential safety hazards

Embodiment 1

[0026] Such as figure 1 As shown, a tower crane slewing mechanism installation device includes a fixed support 2 installed on the slewing support frame 1, a wedge 3 and a connecting piece 4 adapted to the fixed support 2, and the fixed support 2 is the bottom Wide and narrow wedge-shaped, the slope of the wedge 3 is adapted to the upper wedge-shaped slope of the fixed support 2, the upper part of the wedge 3 extends horizontally to form a top cover, and the connecting piece 4 penetrates the top cover to connect the wedge 3 Fixed on the fixed support 2, the slewing support frame 1 is fixed on the side of the slewing mechanism 5, and a bayonet is provided on the rotating arm 6 of the slewing mechanism, and the bayonet is aligned with the fixed support 2 for installation. According to the assembly and force characteristics of the slewing mechanism 5, a fast, simple and stable installation method is developed, and at the same time, the slewing mechanism can be assembled quickly, e...

Embodiment 2

[0034] A method for installing a slewing mechanism of a tower crane. A slewing mechanism arm 6 is provided on the slewing mechanism, a bayonet opening is provided on the slewing mechanism arm, and a mounting assembly detachably engaged by a wedge is provided at the bayonet. The installation device The bottom of the slewing support frame is fixed on the slewing support frame, and the entire installation device is clamped in the bayonet. The key problems to be solved are: 1. The fixed support of the slewing mechanism is directly welded on the slewing support frame, which solves the problem of the installation bolt group of the slewing support frame slewing mechanism. The machining of the mounting holes is cumbersome, and it is difficult to require high precision. 2. Improve the stability of the installation of the slewing mechanism and the efficiency and simplicity of the processing of the slewing support frame and the installation of the slewing mechanism.

Abstract

The invention discloses a tower crane slewing mechanism mounting method. A mounting device comprises a fixed support mounted on a slewing bearing frame, a wedge block matched with the fixed support and a connecting piece, the fixed support is in a wedge shape with the wide lower portion and the narrow upper portion, the inclined face of the wedge block is matched with the upper portion wedge-shaped inclined face of the fixed support, the upper portion of the wedge block horizontally extends to form a top cover, the connecting piece penetrates through the top cover to fix the wedge block on the fixed support, the slewing bearing frame is fixed on the side edge of the slewing mechanism, a bayonet is formed in a rotating arm of the slewing mechanism, and the bayonet is aligned with the fixed support for installation. According to the tower crane slewing mechanism mounting method, and efficient machining of the slewing bearing frame, stable installation of the slewing mechanism and rapid installation of the slewing mechanism are achieved.

Description

technical field [0001] The invention relates to the technical field of tower crane auxiliary equipment, in particular to a method for installing a tower crane slewing mechanism. Background technique [0002] The slewing mechanism is the core mechanism of the tower crane, and the installation and fixation of the slewing mechanism directly affects the safe operation of the entire tower crane. The slewing mechanism is installed on the slewing support frame of the tower crane, and forms an effective cooperation with the slewing support of the tower crane to drive the slewing action of the tower crane. The slewing mechanism decelerates and increases torque through the planetary slewing reducer, and outputs powerful torque to drive the tower crane to rotate. During work, the slewing mechanism mainly bears the slewing torque transmitted from the slewing parts of the tower crane to the slewing mechanism. The torque is transmitted to the slewing ring. At present, the installation a...
