Description

Technical Field

[0001] A traveling guiding mechanism belongs to the technical field of cranes. Background Art

[0002] A bridge crane is the most common heavy object transfer device in the glass production industry. The bridge crane includes a main beam and a traveling crane moving along the main beam. An electric hoist is provided at the traveling crane, and the lifting and lowering of heavy objects are realized through the electric hoist. A fixed plate is arranged inside the traveling crane of the traditional bridge crane. The fixed plate is arranged on both sides of the main beam. Traveling wheels are respectively arranged on the inner sides of the fixed plates on both sides. The traveling wheels are clamped and connected with the main beam. One group of traveling wheels is the driving traveling wheels, and the driving motor is connected with the driving traveling wheels through a speed reducer, so as to drive the traveling crane to move along the main beam.

[0003] After the traditional traveling crane runs for a long time, since it is difficult to make the weights of the electric hoist itself and the heavy objects it carries uniform, the traveling wheels will wear out with the main beam support, resulting in the situation that the electric hoist runs off track. After long-term grinding, the main beam will be damaged or even scrapped. At the same time, the continuous wear of the traveling wheels also brings potential safety hazards to the traveling crane.

[0004] The Chinese invention patent with the application number 201110115640.3, the application date of May 4, 2011, and the patent name of "A New Type of Electric Semi-Gantry Crane" discloses a technical solution. In this technical solution, guiding wheels are arranged on both sides of the main beam, and the situation that the traveling wheels run off track is controlled through the guiding wheels. However, in this technical solution, the guiding wheels are clamped on both sides of the lower edge of the main beam. The following defects are also found in the specific implementation of this technical solution: Since the guiding wheels are clamped on both sides of the lower edge of the main beam, not only the assembly accuracy requirements are relatively high, but also the lower edge of the main beam has a small thickness, so the guiding wheels will be worn after long-term use. After the wear reaches a certain degree, the situation that the traveling wheels run off track will also occur. Therefore, designing a technical solution that can avoid the wear of the guiding wheels and at the same time reduce the assembly accuracy has become an urgent problem to be solved in this field.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: In this traveling crane guiding mechanism, by arranging the guide wheels in the middle of the main beam of the traveling crane, while realizing the guiding of the traveling crane and avoiding the deviation of the traveling wheels, the assembly difficulty is reduced.

[0018] Figures 1 - 2 This is the best embodiment of the present utility model. The present utility model will be further described below with reference to the attached drawings. Figures 1 - 2 Make a further description of the present utility model.

[0019] As Figures 1 - 2 shown, a driving guiding mechanism includes fixing plates 1 arranged on both sides of the driving main beam 2 of the vehicle. The two fixing plates 1 are arranged opposite to each other. A bottom plate 15 is arranged between the two fixing plates 1. The bottom plate 15 is below the driving main beam 2 of the vehicle, and its two sides are respectively fixed to the two fixing plates 1.

[0020] Walking wheels 5 are respectively arranged on the inner sides of the two fixing plates 1. The walking wheels 5 on both sides are respectively in rolling connection with the upper surfaces of the corresponding lower edges of the driving main beam 2 of the vehicle. A speed reducer 7 is installed on the side of one of the fixing plates 1 through a mounting plate 6. The output end of the speed reducer 7 is connected to one of the walking wheels 5. A driving motor 10 is installed at the input shaft of the speed reducer 7. The motor shaft of the driving motor 10 is connected to the input shaft of the speed reducer 7. The walking wheel 5 connected to the speed reducer 7 is the driving wheel, and the remaining walking wheels 5 are the driven wheels.

[0021] Fixing rods 8 are respectively arranged at both ends of each fixing plate 1. The fixing rods 8 are made of square steel. The inner sides of each fixing rod 8 are fixed by a plurality of bolts passing through the fixing plates 1. Guide bolts 9 are also arranged at the ends of the fixing rods 8. After the guide bolts 9 penetrate through the fixing rods 8 and the fixing plates 1 at the same time, they are fixed by two nuts inside and outside.

[0022] A guide wheel frame 3 is fixed to the inner ends of the two guide bolts 9 respectively. A guide wheel 4 is arranged in each of the guide wheel frames 3 on both sides. The guide wheels 4 on both sides are respectively in contact with the middle part of the driving main beam 2 of the vehicle.

[0023] An extrusion bolt 14 is arranged at each end of the bottom plate 15. The bottom of the extrusion bolt 14 is fixed by a nut. The upper end of the extrusion bolt 14 passes through the bottom plate 15 and is fixed with an extrusion wheel frame 11. A spring 13 is also sleeved on the outer ring of the extrusion bolt 14. The spring 13 is located between the extrusion wheel frame 11 and the bottom plate 15. The spring 13 pushes the extrusion wheel frame 11 upward, so that the extrusion wheel 12 is closely attached to the bottom of the driving main beam 2 of the vehicle.

[0024] The specific working process and principle are as follows: When the driving motor 10 works, it drives the rotation of the driving wheel in the traveling wheel 5 through the speed reducer 7, so as to realize the movement of this traveling crane guiding mechanism along the main beam 2 of the traveling crane. The same as the prior art, an electric hoist (not shown in the figure) is also provided on this traveling crane guiding mechanism. When the electric hoist is moved above the heavy object to be transported, the driving motor 10 stops working. After the electric hoist hooks the heavy object and lifts the heavy object, the driving motor 10 works again to transfer the heavy object to the target position, and finally the heavy object is lowered to the target position by the electric hoist.

[0025] During the process of the guiding mechanism moving according to the above, first, the main beam 2 of the traveling crane is clamped by the guiding wheels 4 on both sides. While realizing the guiding function, it avoids the phenomenon of the traveling wheels 5 running off track. At the same time, the extrusion wheels 12 at the bottom are used to make the traveling wheels 5 on both sides closely adhere to the upper surface of the lower edge of the main beam 2 of the traveling crane, further ensuring the stability of the traveling wheels 5 on both sides during operation.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
