Description
Technical Field
The utility model relates to a staircase uninstallation guide rail connecting device.
Background
In the prior art, the connecting devices for connecting the unloading guide rail of the escalator to the drive side plate generally comprise a clamping piece, a shim, a fastening plate and a hexagon head bolt. When it is necessary to adjust the relative positions of the discharge guide and the driving side plate, more shims need to be inserted between the brackets fixed to the driving side plate and the discharge guide.
However, in the prior art, before inserting the shim, the tension spring must be driven loosely to reduce the pressure of the step chain on the unloading rail, thereby leaving room for inserting the shim. After the shim is inserted, the unloader rail clamp is tightened and the tension spring tightened, and the position of the unloader rail is rechecked and measured. If the measurement fails to reach the desired range, the above steps are repeated.
In the prior art, when two or more shims are inserted, the length of the bolt is not sufficient to reach the thickness of the fastening plate, and the length of the bolt is not too long, which would interfere with the internal parts of the unloading rail. In addition, after the bolt is loosened and tightened for many times, the clamping piece is seriously deformed, which results in that the bolt cannot be firmly connected.

Fig. 1 shows a schematic view of an escalator discharge guide track attachment according to an exemplary embodiment of the present invention.
As shown in fig. 1, in the illustrated embodiment, the escalator unloading guide rail coupling device mainly includes a bracket 200, a coupling plate 10, coupling members 20, 21, 22, 23, an upper wedge 11, a lower wedge 12, and an adjustment screw 30.
As shown in fig. 1, in the illustrated embodiment, the bracket 200 is fixed to a drive side plate (not shown) of the escalator. The connection plate 10 is fixed to the bracket 200. The connecting assemblies 20, 21, 22, 23 are used to connect the unloading rail 100 of the escalator to the connecting plate 10. An upper wedge block 11 is fixed to the link plate 10, having an inclined lower surface 11 a. The lower wedge block 12 is movably disposed between the upper wedge block 11 and the unloading rail 100 of the escalator, and has an inclined upper surface 12a engaged with the lower surface 11a of the upper wedge block 11.
As shown in fig. 1, in the illustrated embodiment, the adjustment screw 30 is screwed to the bracket 200, and the lower wedge block 12 can be pushed to move relative to the upper wedge block 11 by rotating the adjustment screw 30 so as to adjust the position of the discharge rail 100 relative to the driving side plate.
As shown in fig. 1, in the illustrated embodiment, when the adjustment screw 30 is rotated, the adjustment screw 30 pushes the lower wedge block 12 to move relative to the upper wedge block 11 in the illustrated horizontal direction X. When the adjustment screw 30 pushes the lower wedge 12 to move, the lower wedge 12 moves along the inclined lower surface 11a of the upper wedge 11 and pushes the discharge rail 100 to move in the vertical direction Z perpendicular to the horizontal direction X with respect to the driving side plate.
As shown in FIG. 1, in the illustrated embodiment, the web 10 is L-shaped and may be referred to as an L-shaped plate. The connection plate 10 includes a plate-shaped main body 10a and a plate-shaped end 10b located at one end of the plate-shaped main body 10a and perpendicular to the plate-shaped main body 10 a. The upper wedge blocks 11 are fixed to the bottom of the plate-shaped body portion 10a of the connection plate 10, and the plate-shaped end portion 10b of the connection plate 10 is fixed to the bracket 200.
As shown in fig. 1, in the illustrated embodiment, the adjustment screw 30 is screwed into the plate-shaped end portion 10b and a screw hole on the bracket 200, thereby fixing the connection plate 10 to the bracket 200.
As shown in fig. 1, in the illustrated embodiment, the escalator discharge guide connecting device further includes a spacer 31, and the spacer 31 is padded in the gap between the plate-like end 10b of the connecting plate 10 and the bracket 200. The adjusting screw 30 passes through the spacer 31.
As shown in fig. 1, in the illustrated embodiment, an upper wedge block 11 is welded to the bottom of a plate-shaped main body portion 10a of the connecting plate 10. However, the present invention is not limited to the illustrated embodiment, and the upper wedge 11 and the connecting plate 10 may be integrally formed.
As shown in fig. 1, in the illustrated embodiment, the inclined lower surface 11a of the upper wedge 11 and the inclined upper surface 12a of the lower wedge 12 are both inclined smooth planes.
As shown in fig. 1, in the illustrated embodiment, the connection assembly 20, 21, 22, 23 includes a screw 20, a nut 21, and a fastening plate 22. The screw 20 passes through the connecting plate 10 and the unloading rail 100. A nut 21 is threadedly coupled to an upper end of the screw 20, and a fastening plate 22 is threadedly coupled to a lower end of the screw 20.
As shown in fig. 1, in the illustrated embodiment, the connection assemblies 20, 21, 22, 23 include a plurality of nuts 21, e.g., double nuts 21. A plurality of nuts 21 are threadedly coupled to the upper end of the screw 20.
As shown in fig. 1, in the illustrated embodiment, the coupling assemblies 20, 21, 22, 23 further include a locking washer 23, the locking washer 23 being fitted over the upper end of the threaded rod 20 and compressed between the nut 21 and the coupling plate 10.
Fig. 2 shows a schematic view of an escalator discharge guide track attachment according to another exemplary embodiment of the present invention.
The escalator unloading guide rail coupling device shown in fig. 2 differs from the escalator unloading guide rail coupling device shown in fig. 1 only in the mating surface characteristics of the upper wedge 11 and the lower wedge 12.
In the embodiment shown in fig. 2, a toothed structure is formed on the lower surface 11a of the upper wedge block 11 and the upper surface 12a of the lower wedge block 12, respectively, such that the lower surface 11a of the upper wedge block 11 and the upper surface 12a of the lower wedge block 12 have a saw-toothed shape in section. The upper wedge 11 and the lower wedge 12 with the toothed structure can obtain larger friction force and more accurate step distance adjustment.
As shown in fig. 1, in the illustrated embodiment, the upper wedge 11 and the lower wedge 12 have sufficient material and strength to resist the large pressure of tightening. The adjusting screw 30 can be rotated through the threaded holes of the L-shaped link plate 10 and the bracket 200 to jack the lower wedge 12 against the upper wedge 11 without loosening and tightening a tension spring (not shown). In addition, the threaded rod 20 is of sufficient length to accommodate the range of adjustment.
As shown in fig. 1, in the illustrated embodiment, the upper wedge block 11 and the lower wedge block 12 have inclined surfaces 11a, 12a that cooperate with each other, thereby forming a distance adjustment mechanism. When it is desired to adjust the position of the discharge guide rail 100 relative to the drive side plates, the double nut 21 is first unscrewed. At this time, although the tension spring is kept in a tensioned state, the upper wedge block 11 is not moved upward by the pressure because it is fixed to the bracket 200 by the adjustment screw 30. Next, adjusting screw 30 is rotated, which moves through threaded holes in L-shaped connecting plate 10 and bracket 200, to push lower wedge 12 toward upper wedge 11. Since the upper wedge 11 is welded to the L-shaped link plate 10 and is fixed to the bracket 200 by the adjustment screw 30, the lower wedge 12 moves downward along the inclined surfaces 11a, 12 a. Thereby, the unloading rail 100 is pushed by the lower wedge block 12 to move downward against the upward pressure generated by the tension. Finally, the rotary adjusting threaded rod 5 is extended downward by a suitable length of the fastening plate 22 and is fixed by tightening the double nut 21.
