Description

Beam structure of road roller and road roller Technical Field The application relates to a road roller part technology, in particular to a beam structure of a road roller and the road roller. Background At present, the main frame of the road roller comprises a front frame, a rear frame and a hinged frame, wherein the front frame comprises a front cross beam and a rear cross beam which are connected with each other. Wherein, the rear cross beam on the front frame is connected with the rear frame through a hinge bracket. In the related art, the rear cross beam is connected with the hinge bracket through a hinge seat welded on the rear cross beam. However, the joint position of the rear cross beam and the hinged seat is easy to cause fatigue cracking of the welding seam due to stress concentration under the influence of factors such as vibration impact of a vibration wheel of the road roller, huge shearing force during abrupt steering and the like, so that the normal work of the road roller is influenced. Disclosure of utility model The application provides a beam structure of a road roller and the road roller, which are used for solving the technical problem that the strength of the connecting structure of a rear beam and a hinged seat of the road roller is poor in the related art. In one aspect, the present application provides a beam structure for a road roller, comprising: a beam body; The hinged seat comprises a mounting platform and at least one mounting plate arranged on the mounting platform, wherein the mounting platform is used for being connected with a hinged frame of a rear frame of the road roller, the mounting plate is inserted on the beam body, the mounting plate extends to a second side surface of the beam body through a first side surface of the beam body, and the first side surface and the second side surface are oppositely arranged; the mounting platform is in butt joint with the first side face and is connected, and the mounting plate is connected with the second side face. In some possible embodiments, the beam body has a receiving cavity, and a mounting groove penetrating the receiving cavity, the first side surface and the second side surface is formed in the beam body, and the mounting plate is inserted into the mounting groove. In some possible embodiments, an end of the mounting plate inserted into the mounting slot is flush with the second side. In some possible embodiments, the mounting plate is welded to the second side and/or the mounting platform is welded to the first side. In some possible embodiments, the plane of the mounting plate is perpendicular to the axis of the beam body. In some possible embodiments, the mounting platform has a through hole, the mounting plate is disposed on the mounting platform through the through hole, and the mounting plate is welded with the mounting platform. In some possible embodiments, two mounting plates are disposed on the mounting platform at intervals, and the two mounting plates are inserted into the beam body. In some possible embodiments, the hinge bracket further comprises a support bearing seat, wherein two ends of the support bearing seat are respectively correspondingly connected with the two mounting plates, and the support bearing seat is used for penetrating through the joint bearing of the hinge bracket. In some possible embodiments, the mounting platform is provided with a mounting hole for mounting the knuckle bearing, the mounting hole being arranged coaxially with the support bearing seat.
