Description

Double-beam metallurgical bridge crane Technical Field The utility model belongs to the technical field of cranes, and particularly relates to a double-beam metallurgical bridge crane. Background In the metallurgical production process, a crane is generally adopted to hoist molten metal and high-temperature materials. Metallurgical plants often have a lot of dust which can accumulate on the trolley track forming grinding media between the wheels and the track, accelerating the scoring of the track surface, causing abnormal wear of the rim. In the prior art, cleaning brushes corresponding to the trolley tracks are usually arranged at two ends of the trolley frame respectively, and the trolley tracks are cleaned through the cleaning brushes in the moving process of the trolley, so that the purpose of cleaning dust on the trolley tracks is achieved. However, when the trolley moves, the cleaning brush at the front end of the trolley frame mainly cleans the track in the moving direction, and the cleaning brush at the rear end of the trolley increases friction with the track, so that unnecessary abrasion between the cleaning brush and the track is caused, and the service life of the cleaning brush is influenced. Therefore, a double-beam metallurgical bridge crane capable of adjusting different cleaning brushes to be in contact with a rail according to the moving direction of the trolley is required to be designed, unnecessary abrasion of the cleaning brushes is reduced, and the service life of the cleaning brushes is prolonged, so that the technical problem faced at present is solved. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model provides the double-beam metallurgical bridge crane which can adjust different cleaning brushes to contact with a track according to the moving direction of the trolley, reduce unnecessary abrasion of the cleaning brushes and prolong the service life of the cleaning brushes. The technical scheme is that the double-beam metallurgical bridge crane comprises two beams which are arranged in parallel, wherein a track is fixedly arranged at the top of each beam, a trolley frame is arranged on each track, two brackets are symmetrically arranged at two ends of each trolley frame, the ends of each bracket are hinged with the beams, cleaning brush assemblies corresponding to the tracks are arranged at the bottoms of the two ends of each beam, and a driving part for driving the beams to outwards turn at least 90 degrees or reset is arranged on each trolley frame. Further, the cleaning brush assembly is provided with a brush plate, bristles are arranged at the bottom of the brush plate, and the brush plate is vertically and slidably connected with the bottom of the cross beam. Further, two guide rods are symmetrically arranged at the top of the brush plate, the guide rods are vertically and slidably connected with the cross beam, and a limiting plate is fixedly arranged at the top end of each guide rod. Further, an electromagnet corresponding to the middle part of the top surface of the brush plate is fixedly arranged at the bottom of the cross beam and used for adsorbing or releasing the brush plate. Further, the bottom of the brush hair is provided with a U-shaped notch matched with the track. Further, a first hinge seat is arranged at the middle of the top of the cross beam, two second hinge seats are symmetrically arranged at the top of the cross beam, the height of the first hinge seat is twice that of the second hinge seat, the end part of the support is hinged with the second hinge seat, one end of the driving part is hinged with one end of the trolley frame, and the other end of the driving part is hinged with the end part of the first hinge seat. Further, the driving component is an air cylinder, a hydraulic cylinder or an electric push rod. Further, the driving part drives the beam to turn outwards by 90 degrees. The utility model has the beneficial effects that: (1) According to the utility model, the driving part drives the cross beam to turn outwards for at least 90 degrees or reset, so that the cleaning brush component is far away from the track or is contacted with the track, when the cleaning brush component is contacted with the track, the track can be cleaned along with the movement of the trolley frame, and the cleaning brush component is far away from the track, so that the abrasion of the cleaning brush component when the trolley frame moves can be reduced; (2) In the process that the trolley frame moves along the track, the cleaning brush component at the front end in the moving direction is controlled to be in contact with the track, the track is cleaned, the cleaning brush component at the rear end is far away from the track, unnecessary abrasion is reduced, and the service life of the cleaning brush component is prolonged.
