Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment, a portal frame for villa elevator car, refer to fig. 2-4, including support body 1, support body 1 includes two vertical beams, and the lower extreme of vertical beam is fixed with 2 bottom end rails.

The upper end of the frame body 1 is provided with two upper beams 3 which are arranged in parallel, and the upper beams 3 are fixed with the vertical beams.

An insertion hole 33 for installing the diverting pulley 2 is provided between the two upper beams 3, and the insertion hole 33 is used for inserting the rotating shaft of the diverting pulley 2, so that the diverting pulley 2 can rotate between the two upper beams 3.

The cross section of the upper beam 3 is concave, which is mainly to increase the bending strength of the upper beam 3.

The upper girder 3 comprises a main plate 31 and short plates 32 on both sides of the main plate 31, the short plates 32 of the two upper girders 3 are arranged to be apart,

a bearing plate 4 is arranged below the

upper beam

3, and 2

bolts

5,2 bolts 5 inserted into the bearing plate 4 are respectively arranged on the short plates 32 of the 2 upper beams 3; the same first nut 61, second nut 62 and third nut 63 are sequentially mounted on 51,2 bolts 5 hung on the cap portions 5363 of the bolts 5 from top to bottom, the first nut 61 butts against the upper surface of the short plate 32 to realize that the bolts 5 are hung on the short plate 32, the second nut 62 butts against the lower surface of the short plate 32, and the third nut 63 butts against the upper surface of the bearing plate 4.

In this design, contradict short plate 32 through first nut 61 for bolt 5 can hang on short plate 32, can adjust the vertical position of bolt 5 relative short plate 32 through rotatory first nut 61 certainly, realizes reciprocating of bolt 5, has certainly just also driven reciprocating of accepting board 4.

The second nut 62 and the third nut 63 are mainly used for clamping the short plate 32 by matching the second nut 62 and the first nut 61 after the diversion sheave 2 is installed, so that the bolt 5 is fixed;

the bearing plate 4 is clamped by the third nut 63 and the cap part 51, so that the bearing plate 4 is fixed;

after the diversion sheave 2 is installed, the bearing plate 4 is used as a connecting bridge plate to further connect the 2 upper beams 3, so that the overall structural strength of the upper beams 3 and the frame body 1 can be improved.

For the bearing plate 4, the bearing plate 4 is a rectangular steel plate, the bearing plate 4 is positioned right below the jack 33, the upper surface of the bearing plate 4 is provided with an arc groove 41, and the circle center of the arc groove 41 and the jack 33 are on the same vertical line;

the design is that when the diverting pulley 2 is placed on the bearing plate 4, the position of the rotating shaft of the diverting pulley 2 and the position of the insertion hole 33 can be aligned by rotating the diverting pulley 2 on the bearing plate 4.

The bolt 5 is provided with a first mark coating 71, and when the first nut 61 is positioned on the first mark coating 71, the distance from the groove bottom of the circular arc groove 41 to the insertion hole 33 is equal to the radius of the pulley 2. The bolt 5 is provided with a second mark coating 72, and when the first nut 61 is positioned on the second mark coating 72, the distance from the groove bottom of the arc groove 41 to the insertion hole 33 is 5cm larger than the radius of the diverting pulley 2.
