Summary of the invention
The purpose of this utility model is to provide that a kind of system is reliable, multi-functional, load-carrying capacity is large, and four suspension centres can be realized stepless transformation, thereby meets the electric hydaulic bont of the large part lifting demand of disparity items.
As follows for realizing the technical scheme that the purpose of this utility model adopts: a kind of electric hydaulic bont, it is characterized in that, comprise girder, the portal frame of column and lifting beam composition, lifting beam is positioned at the top of girder and perpendicular with girder, column is positioned at the bottom of girder, column and girder junction are provided with rigid support, girder and lifting beam are box beam structure, between two girders of the same side, be provided with crossbeam and diagonal brace, GYT hydraulic lifting apparatus is placed in lifting beam, the cable wire of GYT hydraulic lifting apparatus is connected with the hydraulic jack of GYT hydraulic lifting apparatus, cable wire is connected with thing to be hoisted, the traveling gear that drives portal frame walking is equipped with in the bottom of column.
Technical characterictic of the present utility model also has: between described column and girder, adopt high strength bolt to be connected, be provided with the bolt connecting hole of 13 diverse locations on girder.
Technical characterictic of the present utility model also has: between described column and the walking carriage of traveling gear, adopt high strength bolt to be connected.
Technical characterictic of the present utility model also has: between described column and walking carriage, be also connected with and added segmented column by high strength bolt.
The Heave Here of the main equipments such as combustion machine, electrical generator arranges difference, therefore in the time of design, will realize four suspension centre stepless transformations, and the horizontal and vertical position of suspension centre will arrange according to the suspension centre of lifting part.The design of this suspender above girder lifting beam, bont is installed in lifting beam and has been realized this object, bont is realized the longitudinal sliding motion of thing to be hoisted in lifting beam by cable wire, thereby realizes the adjusting of the lengthwise position of thing to be hoisted; Lifting beam is by traveling gear transverse shifting in orbit simultaneously, and the horizontal position that can realize thing to be hoisted regulates.
The height of foundation that simultaneously fires machine, electrical generator is different with the each project of width, will realize that the hoisting depth of a whole set of suspender is adjustable, span is adjustable in when design.Between this suspender column and girder, adopt high strength bolt to be connected, it is optional that its connection location has 13 positions, thereby it is adjustable to have realized two column spans; Between column and the walking carriage of traveling gear, adopt high strength bolt to be connected, the height setting that can require according to disparity items adds segmented column, and to have realized hoisting depth adjustable.
The equipment such as combustion machine, electrical generator are all visual plants, and weight is large, it is high to be worth, and therefore in the time of lifting, will guarantee that it is steadily mobile in place, and this TV station suspender is controlled walking with regard to the control system that has adopted tandem to regulate in the time of design, guarantees that hoisting process is steady.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation sketch of electric hydaulic bont, and accompanying drawing 2 is left views of accompanying drawing 1.Wherein 1: lifting beam; 2: girder; 3: column; 4: traveling gear; 5: crossbeam; 6: diagonal brace; 7: rigid support.
The specific embodiment
The utility model comprises girder 2, the portal frame that column 3 and lifting beam 1 form, lifting beam 1 is positioned at the top of girder 2 and perpendicular with girder 2, column 3 is positioned at the bottom of girder 2, column 3 is provided with rigid support 7 with girder 2 junctions, girder 2 and lifting beam 1 are box beam structure, between two girders 2 of the same side, be provided with crossbeam 5 and diagonal brace 6, GYT hydraulic lifting apparatus (not shown) is placed in lifting beam 1, the cable wire of GYT hydraulic lifting apparatus is connected with the hydraulic jack of this hydraulic lifting apparatus, cable wire is connected with thing to be hoisted, the traveling gear 4 that drives portal frame walking is equipped with in the bottom of column 3.
