Description

Lifting appliance capable of adjusting bridge deck balance Technical Field The utility model relates to the technical field of concrete prefabricated part hoisting, in particular to a lifting appliance capable of adjusting bridge deck balance. Background The bridge deck slab is used as a common concrete prefabricated part and is mainly paved on the top of a bridge, a plurality of bridge deck slabs are finally fixedly connected together through reserved position pouring, a layer of concrete structure is paved on the bridge deck slabs after the bridge deck slabs are connected, and then a layer of asphalt layer is paved, so that bridge deck construction is completed. The bridge deck is heavy as a whole, and needs to be hoisted by a large-scale lifting appliance, particularly in a production workshop, not only is the bridge deck hoisted to a designated position for storage after being integrally poured, but also the bridge deck is hoisted when being sold for transportation. However, the existing lifting appliance is basically formed by integrally lifting the bridge deck by two lifting hooks or one lifting hook, the bridge deck is easy to deflect when the bridge deck is relatively longer in surface, particularly, when structures on two sides of the bridge deck are different, the bridge deck is easier to incline in the lifting process, the lifting after incline deepens the load weight of a steel wire rope, if one side of the bridge deck with heavy weight breaks due to overrun of the traction force of the steel wire rope, serious safety accidents are caused, and therefore the lifting appliance capable of balancing the bridge deck is designed and has great practical value. Disclosure of utility model The utility model aims to provide a lifting appliance capable of adjusting the balance of a bridge deck so as to solve the problems in the background art. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The utility model provides an adjustable bridge deck balance's hoist, includes hanging beam, fixed pulley and movable pulley, the top both sides fixed mounting of hanging beam has wire rope, evenly has seted up the installation on the plate body of hanging beam the locating hole of fixed pulley, the fixed pulley has a plurality ofly at the internally mounted of hanging beam, and the fixed pulley passes through the traction rope and is connected with the movable pulley transmission, hangs on the movable pulley and is equipped with the lifting hook. In the scheme, the hanging beams are provided with two anchoring pieces, the two sides of the top of the hanging beams are provided with the anchoring pieces, the whole anchoring piece is of a long-strip trapezoid structure, and the two sides of the anchoring pieces are fixedly connected with the two hanging beams. As a preferable scheme, an anchoring head facing the pulling direction of the steel wire rope is arranged at the top of the anchoring piece, and the working end of the anchoring head is fixedly connected with the steel wire rope through a rope lock. In the scheme, the hanging beam comprises side plates, and the fixed pulleys are arranged between the two side plates through positioning holes and matched with the rotating shafts.
