Embodiment Construction

[0010] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 , figure 2 Shown: a heavy-duty chain roller row, including a roller bracket 1 as a base, in practical applications, this roller bracket 1 can be connected to a three-dimensional positioning vehicle to carry heavy objects, and can also be directly hoisted On the support surface thereon; along the outside of the outline of the roller rack, there are a plurality of rotatable (self-rotating) stick rows 2, and all the stick rows 2 are connected by chain pieces 3 arranged at both ends to form a Roller strips, which are connected end to end in a ring shape, are set on the outside of the roller frame 1, and the two ends of each stick row 2 (that is, the lateral sides of the roller strip) are respectively provided with limit blocks 4 , to prevent the roller belt from moving laterally during the movement; baffles 5 are fixedly connec...

Abstract

The invention discloses a heavy-load chain roller row, which comprises a roller row frame (1), and is characterized in that a plurality of rotatable roller rows (2) are arranged along the outer side of the outline of the roller row frame (1); all roller rows (2) are connected into an annular roller row belt through chain sheets (3); the roller row belt is sleeved outside the roller row frame (1); both sides of the roller row belt are provided with limiting chock blocks (4); baffle plates (5) are fixedly connected to the two transverse sides of the roller row frame (1) respectively; a track is arranged below the roller row frame (1); and the upper end face of the track is contacted with the roller rows (2). The heavy-load chain roller row is simple in structure, and is skillful in design; and the conventional point contact roller is changed into a liner contact structure, so that the heavy-load chain roller row has the characteristics of high bearing capability, small size and low cost.

Description

technical field [0001] The invention relates to a load rolling device, in particular to a heavy-duty chain roller row. Background technique [0002] At present, fixed rails and heavy-duty transport vehicles are used for heavy-duty transportation of more than 2,000 tons and long-distance transportation (such as hundreds of meters or more). However, whether it is a train rail or a crane rail, the wheels rolling on it are theoretically in point contact. When the contact stress is greater than the allowable stress of the material, pitting corrosion will occur; first, pitting occurs on the surface of the wheel and rail, and then It is peeling, damaged and scrapped. Therefore, the corresponding norms stipulate the maximum permissible wheel pressure for different materials and different wheel diameters. For example, if the material is ZG50SiMn low-alloy steel wheel with a diameter of φ900mm, the maximum wheel pressure on the QU80 rail is 50t, and the maximum wheel pressure on the...
