Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present invention.
Fig. 1 to 5 show a height-adjustable angle steel bottom beam structure according to the present invention, on which a main frame of an escalator is mounted. The structure comprises an adjustment unit and a base plate 3. At least two groups of the adjusting units are arranged in parallel, and the adjusting units of the embodiment are arranged in two groups, and the two groups are separated by a preset interval. The adjusting unit comprises a first angle steel 1, a second angle steel 2 and an adjusting bolt 4. The first angle steel 1 and the second angle steel 2 of this embodiment are equilateral angle steel or unequal angle steel in the prior art. The first angle 1 comprises a first side 11 and a second side 12. The second angle 2 comprises a third side 21 and a fourth side 22. Wherein the angle formed between the first side 11 and the second side 12 is preferably 90 ° depending on the actual design requirements. The included angle of the second angle steel 2 is equal to that of the first angle steel 1.
The second angle steel 2 is arranged above the first angle steel 1 in the same direction. The first side 11 corresponds to the third side 21 in a vertically sliding fit connection along the width direction of the first side 11 or the third side 21. The second side 12 corresponds to the fourth side 22 in a vertical direction with a movement distance therebetween. The aforementioned adjusting bolt 4 is used to adjust the size of the moving distance. Specifically, the adjusting bolt 4 is screwed to the fourth side 22 through the mating screw hole 221, and the adjusting bolt 4 has an abutment end facing the outer side of the second side 12, the abutment end being adapted to abut against the outer side of the second side 12. By rotating the position of the adjusting bolt 4 in the forward and reverse directions, the abutting end of the adjusting bolt 4 abuts against the second side edge 12, so that the fourth side edge 22 is pushed to move towards the direction approaching or separating from the second side edge 12, and the second angle steel 2 is pushed to move along the width direction of the first side edge 11 or the third side edge 21. The central axis of the adjusting bolt 4 of the present embodiment is perpendicular to the outer side face of the second side. The bottom plate 3 is respectively connected with the second angle steel 2 of each group of adjusting units. When the second angle steel 2 moves, the bottom plate 3 moves along. The two groups of the adjusting bolts 4 are arranged at intervals along the length direction of the second angle steel 2.
The lock nut 41 is screwed to the aforementioned adjusting bolt 4. The lock nut 41 is adapted to cooperate with the outer side surface of the fourth side 22 and lock the adjusting bolt 4. The movement distance between the second side 12 and the fourth side 22 is smaller, and the lock nut 41 of the present embodiment cannot enter the movement distance. The locking nut 41 can only be installed at the outer side position of the second angle steel 2, and locking operation of the locking nut 41 is facilitated.
Wherein, the third side 21 is provided with a first kidney-shaped hole 211. The first kidney-shaped hole 211 extends in the width direction of the third side 21. The first side 11 is provided with a first threaded hole 121 corresponding to the first kidney-shaped hole 211. The fastening bolt 5 is inserted into the first kidney hole 211 and is in threaded connection with the first threaded hole 121, so that the first side 11 and the third side 21 can be locked, and the first angle steel 1 and the second angle steel 2 can be fixed. The fastening bolts 5 are arranged in two groups in the longitudinal direction of the second angle steel 2.
The second angle steel 2 is provided with a connecting piece 7 in a welding mode. The bottom plate 3 is connected with the connecting piece 7, and after the connection is completed, the bottom plate 3 is horizontally arranged. A plurality of mounting holes are processed on the bottom plate 3, and the host is fixed on the bottom plate 3. The bottom plate 3 and the connecting piece 7 are fixedly connected through a connecting bolt 6. Specifically, the connecting piece 7 is provided with a second threaded hole 71, the bottom plate 3 is provided with a second waist-shaped hole 31 corresponding to the second threaded hole 71, and the connecting bolt 6 is inserted into the second waist-shaped hole 31 and is in threaded connection with the second threaded hole 71, so that locking and fixing between the bottom plate 3 and the connecting piece 7 are realized. The position adjustment of the bottom plate 3 in the horizontal direction is accomplished by adjusting the relative position between the second kidney-shaped hole 31 and the second screw hole 71. Specifically, the second kidney hole 31 extends in the longitudinal direction of the first angle steel 1, so that the position of the bottom plate 3 in the longitudinal direction of the first angle steel 1 can be adjusted.
During specific adjustment, the lock nut 41 and the fastening bolt 5 are loosened, each group of the adjusting bolts 4 is sequentially adjusted, the second angle steel 2 moves obliquely upwards or downwards relative to the first angle steel 1 (the oblique movement can be decomposed into two directions of horizontal and vertical), so that the position of the second angle steel 2 in the vertical direction and the position of the second angle steel in the horizontal direction are adjusted, the position of a host on the bottom plate 3 is further adjusted, and further the tensioning adjustment of a driving chain of the host from the two directions of horizontal and vertical is realized. After the adjustment is completed, the adjusting bolt 4 is locked by the locking nut 41, and the second angle steel 2 is further fastened by the fastening bolt 5.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present invention.
