The all tensioned meter roller of 1 ~ 4# rack outlet, each one group of dam roller in the milling train of the pickling continuous-rolling of production non-orientation silicon steel, amount to 8 groups.Mill speed due to milling train needs to remain on 800 ~ 900 ms/min, therefore very high requirement is had to the good operation of tension meter roll, dam roller, once tension meter roll or dam roller " locking " will produce quality accident to steel band, thus, when " locking " occurs for tension meter roll or dam roller, just need to carry out quick-replaceable to it.
The roll change operation of traditional tension meter roll or dam roller needs 6 ~ 8 people just can complete.With jack, roller is sling after dismounting tension meter roll or dam roller, then by driving, tension meter roll or dam roller are hung out, then with driving, new tension meter roll or dam roller are hung by milling train, finally tap into milling train with jack and return dress.Because the driving of mill area is at full stretch, and the roll change of tension meter roll or dam roller needs operation 4 hours, thus very large on Rolling production impact; In addition, the use of driving, will certainly bury potential safety hazard to staff.
Roll change operation that is how fast, efficient, safe, that complete tension meter roll or dam roller has in high quality become the important topic of attendant and equipment management personnel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of walking dolly, and it can realize carrying out fast, efficient, safe, roll change in high quality to tension meter roll or dam roller.
For solving the problems of the technologies described above, the utility model provides a kind of walking dolly and comprises: parallel longitudinal vehicle frame, laterally recessed vehicle frame and deflecting roller; The recessed vehicle frame of described transverse direction is connected between described parallel longitudinal vehicle frame; Described deflecting roller is arranged on the lower end of described parallel longitudinal vehicle frame; The recessed vehicle frame of described transverse direction comprises: at least 2 reclinate horizontal supports; Described reclinate horizontal support is set in parallel between described parallel longitudinal vehicle frame.
Further, described deflecting roller comprises: 2 directional wheels and 2 universal wheels; Described 2 directional wheels are arranged on the lower end of described parallel longitudinal vehicle frame as front-wheel; Described 2 universal wheels are arranged on the lower end of described parallel longitudinal vehicle frame as trailing wheel.
Further, the angle of bend of described reclinate horizontal support is between 90 °-120 °.
Further, the angle of bend of described reclinate horizontal support is 120 degree.
Further, also comprise: reinforcement; Described reinforcement is arranged between described reclinate horizontal support and described parallel longitudinal vehicle frame.
Further, the material of described parallel longitudinal vehicle frame is angle steel.
Further, the material of the recessed vehicle frame of described transverse direction is channel-section steel.
The beneficial effects of the utility model are:
The walking dolly that the utility model provides, when when carrying out roll change to tension meter roll or dam roller, tension meter roll to be replaced or dam roller only need be placed on walking dolly by staff, again walking dolly is released, then new tension meter roller or dam roller are shifted onto in milling train by walking dolly and carry out installing.It can thus be appreciated that the walking dolly provided by the utility model carries out the roll change of tension meter roll or dam roller, easy to operate, not only reduce the labour intensity of staff, and shorten the roll changing time of tension meter roll or dam roller; Because whole process does not need the intervention of driving, thus the utility model not only also alleviates the use pressure of driving, but also substantially eliminating the potential safety hazard brought by driving use.The utility model achieves fast, efficient, safe, high-quality roll change to tension meter roll or dam roller.
Accompanying drawing explanation
The front view of the walking dolly that Fig. 1 provides for the utility model embodiment;
The left view of the walking dolly that Fig. 2 provides for the utility model embodiment.
Wherein, the parallel longitudinal vehicle frame of 1-, 2-is recessed vehicle frame laterally, 3-directional wheel, 4-universal wheel, 5-reinforcement.
Detailed description of the invention
For setting forth the utility model further for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, be described in detail to according to the detailed description of the invention of walking dolly that the utility model proposes and operation principle.
See Fig. 1 and Fig. 2, the walking dolly that the utility model embodiment provides, comprising: parallel longitudinal vehicle frame 1, laterally recessed vehicle frame 2 and deflecting roller; Laterally recessed vehicle frame 2 is connected between parallel longitudinal vehicle frame 1; Deflecting roller is arranged on the lower end of parallel longitudinal vehicle frame 1.Particularly, deflecting roller comprises: 2 directional wheels 3 and 2 universal wheels 4; 2 directional wheels 3 are arranged on the lower end of parallel longitudinal vehicle frame 1 as front-wheel; 2 universal wheels 4 are arranged on the lower end of parallel longitudinal vehicle frame 1 as trailing wheel.Laterally recessed vehicle frame 2 comprises: at least 2 reclinate horizontal supports; Reclinate horizontal support is set in parallel between parallel longitudinal vehicle frame 1.The angle of bend of reclinate horizontal support is between 90 °-120 °.Preferably, in the utility model embodiment, the angle of bend of reclinate horizontal support is 120 degree.
In order to strengthen the structural strength of the walking dolly that the utility model embodiment provides, the walking dolly that the utility model embodiment provides, also comprises: reinforcement 5; Reinforcement 5 is arranged between reclinate horizontal support and parallel longitudinal vehicle frame 1, in gusseted.
In the utility model embodiment, the material of parallel longitudinal vehicle frame 1 is 4# angle steel.Laterally the material of recessed vehicle frame 2 is 10# channel-section steel.Deflecting roller is the wheel that can bear 500kg weight.
The walking dolly provided by the utility model embodiment carries out the roll change of tension meter roll or dam roller, first dismantles old tension meter roll or dam roller, and tension meter roll or dam roller is sling with jack.Again that walking dolly is other and be parked in below the tension meter roll or dam roller that are lifted to milling train.Then tension meter roll or dam roller are put down and fall on horizontal recessed vehicle frame 2, and release dolly.Again new tension meter roller or dam roller are undertaken installing by the inverted order of dismounting.The walking dolly provided by the utility model embodiment carries out roll change to tension meter roll or dam roller, and the number of operating personnel can reduce to 3 people by 6-8 people, and the activity duration can shorten to 2 hours by 4 hours, and operating efficiency improves 2 times.
