Description
(1) technical field
The utility model relates to a kind of construction hoisting machinery, is specifically related to a kind of suspension tower cap that is used for tower crane.
(2) background technology
There is not the balance coupling of crane arm and equilibrium arm to show at present in construction trade tower crane (hereinafter to be referred as the tower machine) safety device, when in case the change arm of generation specification sheets no standard or counterbalanced weight weight unknown are true, whether the balance coupling can't be known for tower machine crane arm and equilibrium arm, brings hidden danger for tower machine safety.In the tower machine safety device, load moment limiter and load lifting limiter are extremely important, at present, load moment limiter mostly is board-like being hung on beyond the tower cap of bow, load lifting limiter many tower cap outside root raising line track adjusting wheel place, this design has the following disadvantages: (1) two kind of killer is installed in beyond the tower cap, easy damaged in collision in the dismounting, it is fragile that sleet corrodes switch, and be difficult for maintenance.(2) distortion realizes by the tower cap in the load moment limiter action, the tower cap is a formed steel construction spare, and each distortion all can bring some expendable plastic deformation, deformation data difference before and after causing, make the reliability decrease of load moment limiter, this brings hidden danger to safety in production.
(3) summary of the invention
The purpose of this utility model is to overcome above the deficiencies in the prior art, and a kind of simple compactness, multiple functional suspension tower cap are provided.It can realize that the balance coupling of crane arm and equilibrium arm shows; Overcome of the influence of tower cap plastic deformation to the load moment limiter accuracy; Make the balance coupling demonstration of load moment limiter, load lifting limiter and crane arm, equilibrium arm concentrate on tower cap inside, easily maintenance.
The technical solution of the utility model is: a kind of suspension tower cap that is used for tower crane, it is characterized in that, movable tower cap is suspended in fixed tower cap top by one group of vertical weight spring and one group of athwartship moment spring, described vertical weight spring is below the movable tower cap and between above the fixed tower cap, and described athwartship moment spring is between fixed tower cap and movable tower cap strut member; The built-in slide block of fixed tower cap, hinge is arranged on the described slide block, and movable tower cap strut member and hinge are rotatable hinged; Movable tower cap top is equipped with derrick line pulley, crane arm pull bar and balance arm brace, moment, weight switch and the direction board corresponding matching of installing on moment collision block, weight collision block and pointer that install movable tower cap bottom and the fixed tower cap.
The beneficial effects of the utility model: (1) can realize that the balance coupling of crane arm and equilibrium arm shows; (2) overcome of the influence of tower cap plastic deformation to the load moment limiter accuracy; (3) make the balance coupling demonstration of load moment limiter, load lifting limiter and crane arm, equilibrium arm concentrate on tower cap inside; easily maintenance easily protects killer to be subjected to the damaged in collision that sleet corrodes and dismounting brings less, and is simple and compact for structure; multiple functional, high suitable the applying of efficient.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Among the figure: 1 movable tower cap, 2 crane arm pull bars, 3 derrick line pulleys, 4 equilibrium arm pull bars, 5 hoist ropes, 6 vertical weight springs, 7 fixed tower caps, 8 athwartship moment springs, 9 moment collision blocks, 10 moments, 11 hinges, 12 weight collision blocks, 13 weight switch, 14 pointers, 15 direction boards, 16 slide blocks, 17 movable tower cap strut members.
(5) specific embodiment
As Fig. 1, this kind is used for the suspension tower cap of tower crane, comprise movable tower cap 1 and fixed tower cap 7, movable tower cap 1 is suspended in fixed tower cap 7 tops by one group of vertical weight spring 6 and one group of athwartship moment spring 8, described vertical weight spring 6 is below the movable tower cap 1 and between above the fixed tower cap 7, described athwartship moment spring 8 is between fixed tower cap 1 and movable tower cap strut member 17, and being with tower cap line of centers is that benchmark is symmetrically distributed.
The built-in slide block 16 of fixed tower cap upper shed, described slide block 16 two sides and fixed tower cap upper shed inwall bearing fit.Fixedly install hinge 11 on slide block 16, movable tower cap strut member 17 can be around hinge 11 deflections.Movable tower cap 1, movable tower cap strut member 17 can make slide block 16 slide with limitation in the upper shed of fixed tower cap under the effect of hinge 11.
Movable tower cap 1 top is equipped with existing structures such as two derrick line pulleys 3, hoist rope 5, crane arm pull bar 2 and balance arm brace 4; The moment of installing on movable tower cap 1 bottom mounting torque collision block 9, the fixed tower cap 7 10, these two parts are in order to the hoisting moment limitation function; The weight switch 13 of installing on movable tower cap 1 bottom erection weight collision block 12, the fixed tower cap 7, these two parts are in order to the hoisting capacity limitation function.In movable tower cap 1 bottom pointer 14 is installed, on fixed tower cap 7, is provided with the direction board 15 that cooperates with pointer, be used for the balance coupling Presentation Function of crane arm, equilibrium arm.
The utility model can be finished following work:
1, hoisting moment limitation function: when tower machine hoisting moment greater than corresponding operating mode under rated value and less than rated value 110% the time, crane arm pull bar 2 pulling activity tower caps 1 clockwise rotate through the elastic force that hinge 11 overcomes athwartship moment spring 8, drive moment collision block 9 touches the power supply that rising and amplitude increase direction are cut off in moments 10 actions, but the motion that descends and reduce the amplitude direction can be done by mechanism.Increase that switch and collision block quantity can realize reporting to the police, tentering becomes sign indicating number, a fixed sign indicating number luffing, force a plurality of functions such as throw-over.
2, hoisting capacity limitation function: when tower machine hoisting capacity greater than the rated value of corresponding gear and less than rated value 110% the time, the pulling force of hoist rope 5 makes derrick line pulley 3 produce downward power, pulling activity tower cap 1 overcomes the elastic force of vertical weight spring 6 to lower slider through slide block 16, drive weight collision block 12 and touch the power supply that ascent direction is cut off in weight switch 13 actions, but the motion of descent direction can be done by mechanism.
3, the balance of crane arm, equilibrium arm coupling Presentation Function: when the tower machine is not worked, crane arm pull bar 2 and balance arm brace 4 pulling activity tower caps 1 are along hinge 11 cws or rotate counterclockwise, movable tower cap 1 lower end pointer 14 is swung to the left or to the right, as exceed green area shown in the direction board 15, then crane arm, equilibrium arm do not match (needing to adjust counterbalanced weight weight or boom length), otherwise are the balance coupling.
