An escalator or walkway comprises a support structure as described above for supporting the main shaft of the side motor reduction gearbox of the escalator or walkway.
Description
Technical Field
The present disclosure relates to a support structure for a main shaft of a motor reduction gearbox of an escalator or a pedestrian walkway. The present disclosure also relates to an escalator or walkway comprising a support structure as described above for supporting the main shaft of the side motor reduction gearbox of the escalator or walkway.
Background
Some escalators or pedestrian walkways transmit power from the drive unit to the step belt through a side intermediate motor reduction gearbox rather than a drive chain, thereby improving transmission efficiency. The general design requirement for this drive method is to keep the overall dimensions of the escalator the same as a chain driven escalator, even though the main shaft of the side intermediate motor reduction gearbox is much longer than the main shaft of the chain driven escalator.
In the prior art, hollow profiles are used as support beams (also called girders), over which a threaded plate is welded to secure a bearing block for supporting the spindle. Adjustment requirements in the front-rear direction, i.e. the direction of travel of the elevator, and in the left-right direction, i.e. the direction perpendicular to the direction of travel of the elevator, due to manufacturing tolerances, are not taken into account in this solution.
Also used in the prior art are curved shaped support beams with a threaded plate inside the support beam (no welding) with two axial adjustments. However, since the screw plate is located inside the support beam, it is difficult to move the screw plate and fix the screw plate to the spindle bearing holder.
Therefore, there is a need for a new support structure for the main shaft of the side intermediate motor reduction gearbox which can guarantee sufficient strength and rigidity of the whole escalator or pedestrian walkway and which makes the adjustment of the bearing blocks used to support the main shaft (especially in the elevator travel direction and perpendicular to the travel direction), installation and maintenance work more convenient.
SUMMERY OF THE UTILITY MODEL
The general idea of the present disclosure is that the new support structure for the main shaft of the side intermediate motor reduction gearbox uses a machined thick plate as a support beam (also called a truss) and a threaded plate is located in a slotted hole (also called a sliding groove) of the truss for fixing the bearing block.
Each bearing seat of the main shaft is fixed by a reinforced truss supporting beam, and a threaded plate is arranged in a slotted hole of the truss supporting beam. Fasteners such as bolts are attached to the threaded plate through fastener slots provided on the truss support beam.
During field installation and maintenance, the thread plate can be moved back and forth by pulling a pulling rod arranged on the thread plate. Since most escalators or walkways are directly surrounded on the sides by buildings or cladding, there is limited adjustment space for the operator on the outside of the truss. To this end, the present disclosure also provides a front and rear jack screw mechanism and a lateral jack screw mechanism, thereby enabling adjustment of a bearing housing for supporting the main shaft (in the elevator traveling direction and perpendicular to the traveling direction) to a correct position.
Specifically, according to one aspect of the present disclosure, there is provided a support structure of a main shaft for a main shaft of a motor reduction gearbox of an escalator or a pedestrian walkway, wherein: the support structure includes a bearing housing for supporting the spindle.
The support structure further comprises a first adjustment mechanism and a second adjustment mechanism; the first adjustment mechanism adjusts the position of the bearing block relative to the truss support beam in a first direction; the second adjustment mechanism adjusts a position of the bearing housing relative to the truss support beam in a second direction different from the first direction.
According to the above aspect of the present disclosure, the support structure includes a thread plate; the bearing seat is mounted on the thread plate through a fastener; the thread plate is slidable relative to and supported by a truss support beam for mounting the escalator or pedestrian walkway; the fastener is connected to the threaded plate through an elongated fastener slot provided on the truss support beam and through another elongated fastener slot provided on the bearing block; the length direction of the elongated fastener slot is along the first direction; the length direction of the other elongated fastener slot is along the second direction.
According to the above aspects of the present disclosure, the first direction is perpendicular to the second direction; the first direction is parallel to the direction of travel of the escalator or pedestrian walkway; the second direction is perpendicular to the direction of travel of the escalator or pedestrian walkway.
According to the above aspects of the present disclosure, the truss support beam is provided with elongated sliding grooves along the first direction; a portion of the thread plate is slidably disposed in the sliding groove and supported by the truss support beam in the first direction and the second direction.
The sliding groove restricts movement of the thread plate in a third direction perpendicular to the first direction and the second direction.
According to the above aspects of the present disclosure, a pulling rod is provided on the thread plate, and an operator can move the thread plate during installation and maintenance by pulling the pulling rod.
The pulling rod penetrates through a pulling rod slotted hole formed in the truss supporting beam.
According to the above-described aspects of the present disclosure, the first adjusting mechanism includes a first thread mechanism (front and rear thread mechanisms); the first screw mechanisms are arranged on two sides of the bearing seat, one end of each first screw mechanism abuts against one end of the bearing seat, and the other end of each first screw mechanism is rotatably connected to the truss supporting beam through threaded connection.
The first jack screw mechanism moves the bearing housing in the first direction by rotation of the first jack screw mechanism relative to the truss support beam.
According to the above-described aspects of the present disclosure, the second adjusting mechanism includes a second jack-screw mechanism (lateral jack-screw mechanism); the second screw mechanisms are arranged on two sides of the bearing seat, one end of each second screw mechanism abuts against a lug extending from one end of the bearing seat, and the other end of each second screw mechanism is rotatably connected to the truss supporting beam through a threaded connection.
The second jack screw mechanism moves the bearing housing in the second direction by rotation of the second jack screw mechanism relative to the truss support beam.
According to another aspect of the present disclosure there is provided an escalator or walkway including a support structure as described above for supporting the main shaft of the side motor reduction gearbox of the escalator or walkway.
Compared with the solutions in the prior art, the technical solution of the present disclosure has the following technical advantages:
1. the overall strength and rigidity of the truss support beam of the escalator or pedestrian walkway are enhanced, thereby reducing displacement during installation and maintenance.
2. Even in a limited working space, a space for installation and maintenance adjustment can be reserved by pulling the pulling rod fixed to the thread plate.
3. The position of the bearing seat is simply and conveniently adjusted in the elevator advancing direction and in the direction perpendicular to the elevator advancing direction by using the front and rear jack screw mechanisms and the transverse jack screw mechanism, so that the influence of manufacturing tolerance is overcome.
