Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In order to technical solutions according to the invention are described, be described below by specific embodiment.
Fig. 1 and Fig. 2 respectively illustrates the main TV structure of the cantilevered parallel rollers roller replacing device for straightening machine that the embodiment of the present invention provides and right TV structure, illustrate only the part relevant to the embodiment of the present invention for convenience of explanation.
See figures.1.and.2, the cantilevered parallel rollers roller replacing device for straightening machine that the present embodiment provides comprises rail bracket 1, transmission mechanism 2 and roll changing carriage 3, described roll changing carriage 3 is provided with bracket elevating mechanism 4, and described roll changing carriage 3 is moved on described rail bracket 1 by described transmission mechanism 2.
During specific implementation, described bracket elevating mechanism 4 comprises bracket 41 and bottom bracket 42, and both are fixed as one by latch 43.The structural representation of the bracket elevating mechanism shown in composition graphs 3, described bracket elevating mechanism also comprises the hydraulic cylinder 44 and lead vertical shaft 45 and the sleeve 46 of processing on described bottom bracket that are fixed on roll changing carriage, the movable end of described hydraulic cylinder 44 is held bottom described bottom bracket 42, described bracket and bottom bracket are equipped with and assemble the identical curved surface of secondary quantity with roller shell, and it is corresponding that the cover that when described surface location and straightener are in roll change position, upper and lower smoothing roll is installed assembles secondary position.
In this structure, bracket is for supporting roll sleeve on straightener, bottom bracket is for supporting roll sleeve under straightener, connected by latch between upper and lower bracket, upper and lower bracket holds up the curved surface quantity of roller shell and position and strictly corresponds to the secondary position of roller shell assembling that when straightener is in roll change position, upper straightening roll and lower smoothing roll are installed.In diagram, upper and lower bracket is equipped with 5 curved surfaces, 10 secondary roller shell roll changes can be completed.Roller shell assembling pair on upper and lower bracket and bracket can be hung out operation area to area in preparation by crane in the outer operation area in preparation of rolling line together, and is lifted on roll changing carriage, realizes fast roll changing, saves roll changing time.Inclination is had in rolling line direction and rolling line vertical direction after holding up roller shell assembling pair for avoiding bracket, in the present embodiment, each hydraulic cylinder is symmetrically arranged in below bottom bracket, each hydraulic cylinder synchronous lifting under guiding vertical shaft coordinates with the guiding of sleeve, realize the overall steadily lifting of bracket, prevent bracket from tumbling.
As a kind of preferred structure, in Fig. 1 as described in Figure 4, local A enlarged drawing, described rail bracket 1 is provided with track 11, is provided with wheel shaft 31 in described roll changing carriage 3, described wheel shaft two ends are provided with wheel 32, and described wheel is free to rotate and be fitted on described track 11.Driven by described transmission mechanism, roll changing carriage 3 even running on described track 11.Here, the position of centre of gravity after wheel loads onto roller shell assembling pair according to roll changing carriage is arranged, tumbles, ensure stability when roll changing carriage travels at full capacity when preventing roll changing carriage from pulling out roller shell.
In the present embodiment, preferably, transmission mechanism adopts chain drive and mate gear tooth bar, concrete, described transmission mechanism 2 comprises reducing motor 21, is arranged on the driven wheel 22 on described reducing motor 21 output shaft, the power transmission shaft 23 be arranged on described roll changing carriage, in the middle of described power transmission shaft, driven gear (not shown) is installed, power transmission shaft 23 two ends are fixed with synchromesh gear 24, described driven wheel and described driven gear are socketed with chain 25, described rail bracket is also provided with tooth bar 26, and described synchromesh gear engages with described tooth bar.Here, realize mechanical synchronization by power transmission shaft between driven gear and synchromesh gear, during work, reducing motor output shaft rotation, by described chain-driving drive axis, then by rack pinion, roll changing carriage entirety can move forward and backward in orbit.In addition, preferably, described transmission mechanism 2 also comprises the cable drum 27 for folding and unfolding cable.Cable drum 27 is folding and unfolding power line and holding wire when roll changing carriage travels.
Be further used as a kind of preferred embodiment, this device also comprises guiding mechanism 5, as shown in Figure 5, described guiding mechanism 5 comprises the eccentric shaft 51 be arranged on bottom roll changing carriage, described eccentric shaft 51 is provided with directive wheel 52, also be provided with side rails 53 inside described rail bracket, described directive wheel 52 is close to and described side rails 53.The fine-tuning roll changing carriage position of offset of adjustment eccentric shaft, prevents car body at horizontal plane intrinsic deflection, ensures the accurate contraposition that roller shell assembling is secondary further.Therefore, when roll changing carriage has skew on rolling line direction, adjust by the offset adjusting eccentric shaft.Under the effect of roll changing carriage guiding mechanism and synchromesh gear, tooth bar, roll changing carriage effectively can be avoided to offset in motion and reverse, thus ensure that roll changing carriage position when roll change is correct, realize the accurate contraposition of the secondary and smoothing roll of each roller shell assembling.In the present embodiment, guiding mechanism is furnished with everywhere, and each two of one-sided front and back are adjacent to side rails realization guiding.
