specific Embodiment approach

[0010] The specific embodiment: the specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0011] Such as Figure 1-Figure 3 As shown, a central hinged structure of trackless equipment with a swing function, which includes a front frame, a front frame hinged frame 1 connected to the front frame, a rear frame, and a rear frame hinged frame 17 connected to the rear frame , Swing frame 8. The swing frame 8 is an important structural part that realizes the rotation and swing between the front frame hinge frame 1 and the rear frame hinge frame 17. It consists of a horizontal upper swing plate 8-1, a horizontal lower swing plate 8-2, a vertical The side swing plates 8-3 in the vertical direction are connected and formed in an L shape. The upper swing plate 8-1 is provided with an upper hinge hole 8-4, and the lower swing plate 8-2 is provided with a lower hinge hole 8-5. The hole 8-4 is concentric with the lower hinge ...

Abstract

The invention discloses a trackless equipment central hinging structure with a swinging function, which is characterized in that a swinging frame is arranged between a front frame hinging frame and a rear frame hinging frame, an upper hinging shaft is arranged in an upper hinging fixing sleeve connected with the upper end of the front frame hinging frame, and an angular contact bearing coaxial with the upper hinging shaft is arranged in a bearing seat sleeve connected with the swinging frame; a lower hinge shaft is arranged in a lower hinge fixing sleeve and a lower hinge sleeve which are connected with the lower end of the front frame hinge frame, and a joint bearing coaxial with the lower hinge shaft is arranged in a lower hinge bearing gland connected with the swing frame; the swing frame is connected with the bearing supporting sleeve to guarantee coaxial installation with the inner ring of the slewing bearing, the inner ring of the slewing bearing is connected with the swing frame, and the outer ring of the slewing bearing is hinged to the rear frame. The device is convenient to maintain and repair, machining difficulty and cost are reduced, installation is convenient, efficiency is improved, and the failure rate is reduced.

Description

technical field [0001] The invention relates to a central hinged structure of trackless equipment with a swing function, which belongs to the technical field of engineering machinery and mining engineering. Background technique [0002] The central hinge structure of underground trackless equipment is an important part of trackless equipment. This structure needs to connect the front and rear frames to realize the flexible steering of the frame. In underground trackless equipment, in order to make the equipment have better passability and improve the adhesion effect of rubber wheels, a swing frame is often designed on the front drive axle or rear drive axle so that the drive axle can swing within a certain angle. Most of the designs now are to design a swing frame at the installation place of the drive axle, install the drive axle on the swing frame, and install the two ends of the swing frame on the car body through the hinge shaft, and realize the swing of the drive axle t...
