Abstract
The utility model discloses a novel crown block walking device, which comprises a U-shaped frame, walking wheels, a motor, a driving gear, a driven gear and a guide wheel; guide wheels are respectively and rotatably arranged on two side edges of the frame on two sides of the web plate; the central line of the guide wheel is vertical to the lower flange plate. Has the advantages that: the utility model has simple structure and easy realization; the driven gear is effectively prevented from being in contact with the outer edge of the lower flange plate to generate friction and abrasion, the driven gear and the track are prevented from being damaged due to friction and abrasion, the service life of the crown block is prolonged, and the maintenance amount is reduced; meanwhile, the problem that maintenance workers climb up for many times for maintenance is avoided, and potential safety hazards are reduced.
Description
The technical field is as follows:
the utility model relates to a running gear, in particular to novel overhead traveling crane running gear.
Background art:
the existing crown block is widely applied to factory enterprises for conveying materials and the like; as shown in fig. 1, the existing travelling device of the overhead travelling crane travels on an i-shaped track, and comprises a frame 1, travelling wheels 2, a motor 3, a driving gear 4 and a driven gear 5; two opposite sides of the frame 1 are respectively and rotatably provided with a rotating shaft 8; the opposite ends of the two rotating shafts 8 are respectively fixed with a traveling wheel 2, and one side of the frame 1 is fixedly provided with a motor 3; a driving gear 4 is coaxially fixed at the output end of the motor 3, a driven gear 5 is concentrically fixed on one of the rotating shafts 8, and the driving gear 4 is meshed with the driven gear 5; the two walking wheels 2 respectively walk on the lower flange plates 7.2 at two sides of a web plate 7.1 of the H-shaped track 7, and the driven gear 5 is positioned at the outer edges of the lower flange plates 7.2; the crown block walking device has the following problems: 1. when the overhead travelling crane walks on a curved track, the driven gear is easily contacted with the outer edge of the lower flange plate, so that frictional wear is generated, the driven gear and the track are easily damaged, the service life of the overhead travelling crane is shortened, and the maintenance amount is increased; 2. because the track is located higher position, therefore take place to damage the back maintenance comparatively difficult, the maintenance workman need climb and maintain, and then has the potential safety hazard that the maintenance workman fell off.
The utility model has the following contents:
an object of the utility model is to provide a simple structure, and avoided driven gear and track to take place the novel overhead traveling crane running gear of frictional wear.
The utility model discloses by following technical scheme implement: a novel crown block walking device comprises a U-shaped frame, walking wheels, a motor, a driving gear, a driven gear and guide wheels; rotating shafts which are perpendicular to the web plates are respectively and rotatably arranged on the frame on two sides of the web plates of the I-shaped track; the opposite ends of the two rotating shafts are respectively fixed with a traveling wheel, and the wheel surface of each traveling wheel is in contact with the surface of the lower flange plate of the track; the motor is fixedly arranged on the frame on one side of the web plate; the output end of the motor is coaxially fixed with the driving gear, one of the rotating shafts is concentrically fixed with the driven gear, and the driving gear is meshed with the driven gear; the two side edges of the frame at the two sides of the web plate are respectively and rotatably provided with the guide wheels; the center line of the guide wheel is perpendicular to the lower flange plate.
Further, the shortest distance between the wheel surface of the guide wheel and the side surface of the web plate is smaller than the shortest distance between the side surface of the driven gear and the outer edge of the lower flange plate.
The utility model has the advantages that: the utility model has simple structure and easy realization; when the overhead travelling crane walks on a curved track, the guide wheel is in contact with a web plate of the track, so that the driven gear is effectively prevented from being in contact with the outer edge of the lower flange plate to cause frictional wear, the driven gear and the track are prevented from being damaged due to frictional wear, the service life of the overhead travelling crane is prolonged, and the maintenance amount is reduced; meanwhile, the problem that maintenance workers climb up for many times for maintenance is avoided, and potential safety hazards are reduced.

in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the prior art.
Fig. 2 is a schematic view of the overall structure of the embodiment of the present invention.
Fig. 3 is a schematic cross-sectional view of portion a-a of fig. 3.
The specific implementation mode is as follows:
as shown in fig. 2-3, a novel crown block walking device comprises a frame 1 shaped like a U, walking wheels 2, a motor 3, a driving gear 4, a driven gear 5 and a guide wheel 6; rotating shafts 8 which are perpendicular to the web plate 7.1 are respectively and rotatably arranged on the frame 1 at two sides of the web plate 7.1 of the I-shaped track 7; the opposite ends of the two rotating shafts 8 are respectively fixed with a traveling wheel 2, and the wheel surface of each traveling wheel 2 is in contact with the surface of a lower flange plate 7.2 of the track 7; a motor 3 is fixedly arranged on the frame 1 at one side of the web 7.1; a driving gear 4 is coaxially fixed on the output end of the motor 3, a driven gear 5 is concentrically fixed on one of the rotating shafts 8, and the driving gear 4 is meshed with the driven gear 5; guide wheels 6 are respectively and rotatably arranged on two side edges of the frame 1 at two sides of the web 7.1; the center line of the guide wheel 6 is vertical to the lower flange plate 7.2, and the shortest distance between the wheel surface of the guide wheel 6 and the side surface of the web 7.1 is smaller than the shortest distance between the side surface of the driven gear 5 and the outer edge of the lower flange plate 7.2; when the bent track 7 is walked, the guide wheel 6 is contacted with the web 7.1 of the track 7, so that the driven gear 5 is effectively prevented from being contacted with the outer edge of the lower flange plate 7.2 to generate friction and abrasion, the condition that the driven gear 5 and the track 7 are damaged due to friction and abrasion is further avoided, the service life of the crown block is prolonged, and the maintenance amount is reduced; meanwhile, the maintenance worker is prevented from climbing for many times for maintenance, and the potential safety hazard is reduced; the utility model discloses simple structure easily realizes.
