The specific embodiment
Extremely shown in Figure 5 as Fig. 1, a kind of mine crane in bridge type, comprise two horizontally disposed girders 2, be fixedly connected with two end carriages 6 in the end of two girders 2, girder 2 and end carriage 6 constitute crane bridge, end carriage 6 is provided with cart walking mechanism, this cart walking mechanism comprises the wheel that is arranged on the end carriage two ends and is used for the movable motor that drive wheels is rotated, on girder 2, be installed with the guide rail that extends along the girder bearing of trend, guide rail is provided with monkey 1, monkey 1 comprises the dolly chassis 11 that is slidingly mounted on the guide rail, dolly chassis 11 is provided with reel 14, reel 14 is driven by motor 13, be installed with the cantilever beam 12 that extends upward outside place's dolly chassis in reel 14 1 sides on the dolly chassis 11, cantilever beam 12 is inclined to set on the plane that it extends axially on the direction with dolly chassis 11 places, the end away from dolly chassis at cantilever beam 12 is provided with fixed pulley group 124, on fixed pulley group 124, be wound with hauling rope 125, one end of hauling rope 125 is connected on the reel, its other end is fixed with suspender, cantilever beam 12 in the present embodiment comprises fixed beam 122 that is installed on the dolly chassis and the portable beam 126 that cooperates with fixed beam 122 sliding plugs, described fixed pulley group is arranged on the end away from dolly chassis of portable beam, dolly chassis 11 is provided with fixed beam fixed mount 15, opposite position place at fixed beam fixed mount 15 and fixed beam 122 is provided with mounting hole, in mounting hole, be provided with and be used for fixed beam is fixed on fixed pin shaft 16 on the fixed beam fixed mount, between portable beam and fixed beam, be installed with the retractor device that is used for the support fixation portable beam, retractor device in the present embodiment is to be distributed in the piston system of two covers of cantilever beam both sides by the hydraulic power driving, every cover piston system includes piston cylinder 51 and the piston rod 52 that extends along the cantilever beam bearing of trend, on the outer peripheral face of fixed beam 122, be furnished with fixed mount 55, one end of piston cylinder 51 is fixed on the fixed mount 55, the outer peripheral face of portable beam 124 is provided with contiguous block 54, being connected on the contiguous block 54 of piston rod 52 away from the outer end of piston cylinder, because the bilateral symmetry at cantilever beam is furnished with two cover piston systems, therefore, in fixed mount that is provided with on the fixed beam outer peripheral face and all corresponding both sides that are symmetrically distributed in cantilever beam of contiguous block that on the portable beam outer peripheral face, are provided with, be bearing fit in the present embodiment between portable beam and the fixed beam, between portable beam and fixed beam, be furnished with roller 123 along the fixed beam bearing of trend, the eye portable beam is axial arranged on the outer peripheral face of portable beam a roller track, described roller rolls and is arranged in the roller track, the edge has been arranged side by side a plurality of hanging beams 3 perpendicular to the girder bearing of trend between two girder relative inner of hoisting crane, the two ends of each hanging beam 3 are cooresponding to be fixedly connected on two girders 2, be set with the electric block rail bracket that extends along the girder bearing of trend in hanging beam 3 bottoms, electric block rail bracket in the present embodiment is an I-beam section 4, I-beam section 4 is positioned on the hanging beam and the corresponding corresponding section midway location of two girder relative inner place, is slidingly fitted with electric block 5 on I-beam section.
Because cantilever beam stretches out outside the dolly chassis, in order to guarantee that center of gravity still is positioned at whole crane span structure center, therefore can make certain improvements like this in the junction of girder and end carriage.As shown in Figure 2, every butt beam is divided into three sections by two girders, be corresponding to the girder section 61 of the corresponding inboard of two girders be positioned at the end carriage section of girder section both sides on the end carriage, the end carriage Duan Weichang end carriage section 62 of the cantilever beam on the close described dolly chassis in described two end carriage sections, another is short end carriage section 63, described long end carriage section 62 along the length of the axial length of end carriage greater than short end carriage section 63.
Cantilever beam in the foregoing description is that portable beam and fixed beam sliding plug cooperate, and whole like this cantilever beam is scalable adjustment structure, also can be regular length unmodified cantilever beam, but the field of employment that can limit cantilever beam this moment.
As what adopt in Fig. 4, the cantilever beam structure shown in Figure 5 is the piston system that hydraulic power drives, the piston system that also can adopt Pneumatic pressure power to drive, and the structure that is provided in its structure and this enforcement is basic identical.
Between portable beam and fixed beam, be provided with roller in the foregoing description, also can between be installed by stability and the reliability of plain bearing to guarantee that both sliding plugs cooperate.
Be arranged side by side a plurality of hanging beams at two girders, hanging beam can adopt steel construction piece, the electric block rail bracket is set on hanging beam, and on the electric block rail bracket, electric block is installed, thereby auxiliary hook is installed on hoisting crane to save the service life of power and assurance main hook.
Because the cantilever beam that is adopted stretches out outside the dolly chassis in the present invention, prevent that like this dolly from toppling, usually the end away from cantilever beam at dolly chassis is provided with Overthrow preventing device, as shown in Figure 3, Overthrow preventing device is the anti-roller 18 of cantilever dolly that is arranged on the dolly chassis, and the anti-roller of cantilever dolly herein can adopt structure of the prior art.
When the present invention uses, cart walking mechanism drives crane span structure and monkey moves to mine well head appropriate location, monkey slides into the appropriate location of well head along girder, the grafting of adjusting portable beam and fixed beam by hydraulic power system cooperates to guarantee the length of cantilever beam, machine operation, reel drives suspender and hoists by hauling rope, fixed pulley group, and the equipment in the mine well is sling, and end carriage drive girder and monkey are transported to assigned address with equipment then.The fixed beam of cantilever beam is fixed on the fixed beam fixed mount by fixed pin shaft among the embodiment provided by the present invention, thereby is convenient to the on-site installation dismounting, changes to make things convenient for split transportation and maintenance.
