The invention relates to the technical field of cable type crane equipment, in particular to a cable type crane sports car with transversely arranged pulleys, compared with the prior art, the cable type crane sports car with the transversely arranged pulleys is additionally provided with profile steel or a box girder as an anti-bending component, and a wheel axle only bears shear force and no longer bears bending moment, so that the anti-bending and anti-torsion performance is improved; vertical arrangement is changed into transverse arrangement, after improvement, a hoisting cable steering pulley is not located under a walking pulley any more and is transversely staggered by a certain distance, and the condition that a sports car climbs over a cable saddle is not blocked any more; climbing auxiliary devices are additionally arranged on the two sides of a sports car, so that when the sports car climbs over a cable saddle, the sports car is suspended, a sports car walking pulley is disengaged from a bearing cable and located over the bearing cable, the sports car does not make contact with the cable saddle, and the sports car walking pulley falls back to the bearing cable after climbing is completed, and if the climbing auxiliary devices are not additionally arranged, the rims of the pulleys need to be thickened; when the running pulley of the sports car rolls over the cable saddle pulley, the top faces of the rims of the pulleys make contact with each other.
本发明涉及缆索式起重机设备技术领域,特别是一种滑轮横向布置的缆索式起重机跑车,与现有技术相比,该滑轮横向布置的缆索式起重机跑车增设型钢或箱梁作为抗弯部件,轮轴仅承受剪切力而不再承受弯矩,提高了抗弯和抗扭性能;将竖向布置改为横向布置,改进后起重索转向滑轮不再位于行走滑轮的正下方,而是横向错开一定的距离,跑车翻越索鞍不再受阻;在跑车两侧增加翻越辅助装置,使得跑车翻越索鞍期间,跑车被架空,跑车行走滑轮脱离承重索且位于其正上方,跑车与索鞍不接触,待翻越完成后跑车行走滑轮落回承重索之上,若不增加翻越辅助装置,则需对滑轮轮缘进行加厚,使得跑车行走滑轮从索鞍滑轮上滚过,从滑轮上滚过时,各滑轮轮缘顶面相接触。
