Detailed Description

Referring to fig. 3 to 8, the lifting appliance support comprises a bottom plate 1, a baffle plate 2, a rerailing base plate 3, a sleeper beam 4, a lifting appliance reserved notch 5, a limiting bolt circular hole 6, a boss stop 7, anti-skidding textures 8, a fastener 9, a through hole 10, a groove 11, a frame seat 12 and a rerailing jack 13.

The arrangement of the frame saddle 12 comprises the steps that firstly, 4 points are arranged on a car body at positions, which are 1.5-2 meters away from the inside of the sleeper beam 4 in a translation mode, on the basis of the sleeper beam 4, the frame saddle 12 with 8 points is arranged on the whole car, the specific size and the position can be determined according to bogie space and user frame system parameters, the arrangement mode can solve the problem that extra hoisting points are lacked after 4 frame points are occupied during car transportation or frame maintenance, and the specific figure is shown in figure 3.

The structure design of the saddle 12, the saddle 12 is divided into three parts of a bottom plate 1, a baffle 2 and a rerailing backing plate 3. Wherein the bottom plate 1 is made of a plate with the thickness of at least 10mm and the size of not less than 100X400mm, and the bottom surface is machined with anti-skid grains 8; two ends are provided with round holes 6 capable of installing limit bolts; a gap 5 is reserved in the middle for the lifting appliance; boss backstops 7 are arranged at two ends of a bottom plate 1 of the saddle 12, anti-skidding textures 8 are machined on the bottom plate 1, friction force and safety of a contact area can be increased, and slippage between a vehicle and a lifting appliance or a car lifting jack is prevented during vehicle lifting or hoisting, and the detailed description is shown in figure 4.

The baffle 2 is located above the bottom plate 1 and is vertically welded with the bottom plate 1, the thickness is generally 10mm, in order to form a clamping fit structure with the lifting appliance, the distance between the baffle 2 and the lifting appliance is generally 220-240mm, the baffle is provided with circular holes with the diameter of 20-25, and fixed connection points can be provided during transportation, and further, the baffle is respectively located on the bottom plate between the reserved notch of the lifting appliance and the circular holes of the limiting bolts, which is shown in the attached drawings 5 and 6 in detail.
