[0002] The traveling crane girder is the track for the boom of devices such as cranes and hoists in the machining field. These tracks are usually called traveling crane lanes and are the infrastructure for various traveling cranes (including cranes, hoists, etc.) to move and operate in industrial factories.

[0003] The common traveling crane girder is driven to travel on the track by setting driving wheels and driven wheels to realize the traveling of the traveling crane. However, there are some deficiencies: when the driving wheels travel on the track, if the operating driver makes an operating error and causes two traveling cranes to collide, the driving wheels and driven wheels are very easy to disengage from the track, resulting in accidents. Therefore, improvements are needed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing girder is easy to disengage from the track during use.

[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a traveling crane anti-derailment girder, including an I-beam. A traveling beam is arranged above the I-beam. A driven wheel is arranged in the traveling beam and rolls on the I-beam. An overhaul component is arranged in the traveling beam. A driving device is arranged in the traveling beam and rolls on the I-beam. An anti-derailment device is arranged at the lower end of the traveling beam and is located on both sides of the I-beam; the anti-derailment device includes a fixing plate. Two groups of fixing plates are symmetrically arranged with respect to the I-beam. A hydraulic cylinder is arranged on the fixing plate. A frame is arranged at the output end of the hydraulic cylinder. A pressure roller is arranged in the frame. By driving the pressure roller with the hydraulic cylinder, the pressure roller fits in the side groove of the I-beam, which can prevent the traveling beam from derailing during traveling.

A gear ring is arranged on the driving wheel. A speed reducer is arranged on the side wall of the traveling beam. A motor is arranged on the speed reducer. A gear is arranged at the output shaft end of the speed reducer and is meshed and connected with the gear ring. By meshing the gear with the gear ring, the driving wheel can actively travel on the I-beam.

[0007] Further, the overhaul component includes a plugging plate. The plugging plate is buckled in the side wall of the traveling beam and is flush with the end face of the traveling beam. A threaded hole is arranged on the plugging plate. A connecting block is arranged on the plugging plate. Both the driven wheel and the driving wheel rotate in the connecting block. By disassembling the plugging plate, it is convenient to disassemble and overhaul the driven wheel or the driving wheel.

[0008] Preferably, a guide rod is fixedly connected to the frame. The guide rod passes through the fixed plate, and the guide rods are symmetrically arranged above and below the hydraulic cylinder.

[0009] Preferably, the length of the pressure roller is equal to the width of the side groove of the I-beam.

[0010] Preferably, the fixed plate is located at the middle position between the driven wheel and the driving wheel.

[0021] As Figures 1-4 , a traveling anti-derailment walking beam of the present utility model includes an I-beam 1. A walking beam 2 is provided above the I-beam 1. A driven wheel 3 is provided in the walking beam 2 and rolls on the I-beam 1. A maintenance component 4 is provided in the walking beam 2. A driving device 5 is provided in the walking beam 2 and rolls on the I-beam 1. An anti-derailment device 6 is provided at the lower end of the walking beam 2 and is located on both sides of the I-beam 1.

[0022] As Figures 1-2 , the anti-derailment device 6 includes a fixing plate 7. Two groups of fixing plates 7 are symmetrically provided with respect to the I-beam 1. A hydraulic cylinder 8 is provided on the fixing plate 7. The output end of the hydraulic cylinder 8 is provided with a frame 9. A guide rod 19 is fixedly connected to the frame 9. The guide rod 19 penetrates through the fixing plate 7. The guide rod 19 is symmetrically arranged above and below the hydraulic cylinder 8. A pressure roller 10 is provided in the frame 9. The length of the pressure roller 10 is equal to the width of the side groove of the I-beam 1. By driving the pressure roller 10 through the hydraulic cylinder 8, the pressure roller 10 fits into the side groove of the I-beam 1, which can prevent the walking beam 2 from derailing during walking.

[0023] As Figure 1 and 3 , the driving device 5 includes a driving wheel 11. The driving wheel 11 rotates in the walking beam 2 and rolls on the I-beam 1 in alignment with the driven wheel 3. The fixing plate 7 is located at the middle position between the driven wheel 3 and the driving wheel 11. A toothed ring 12 is provided on the driving wheel 11. A speed reducer 13 is provided on the side wall of the walking beam 2. A motor 14 is provided on the speed reducer 13. A gear 15 is provided at the output shaft end of the speed reducer 13 and is meshed with the toothed ring 12. By meshing the gear 15 with the toothed ring 12, the driving wheel 11 can actively travel on the I-beam 1.

[0025] During specific use, when the driving wheel 11 and the driven wheel 3 at the lower end of the walking beam 2 are located on the I-beam 1, by starting the hydraulic cylinder 8, the hydraulic cylinder 8 pushes the frame 9, so that the pressure roller 10 is buckled into the side wall groove of the I-beam 1. The pressure roller 10 can prevent the walking beam 2 from disengaging upward from the I-beam 1 track during walking.

[0026] By starting the motor 14, after decelerating through the reducer 13, the gear 15 meshes with the gear ring 12 to rotate, and the driving wheel 11 will roll and walk on the I-beam 1. The driven wheel 3 will also roll on the I-beam 1, and the walking beam 2 will walk. During the walking process, the pressure roller 10 will roll while fitting the I-beam 1, always maintaining the buckling of the I-beam 1, achieving the purpose of preventing derailment of the walking beam 2 during walking.
