Abstract
The invention discloses a kind of counterbalanced weight for tower crane to move and positioner, it comprises two winchs (8) be arranged on hoisting crane, and the rope of two winchs (8) connects the two ends, left and right of counterbalanced weight (5) respectively; The steelframe (6) of hoisting crane is provided with two symmetrically arranged chutes (2), the both sides, front and back of counterbalanced weight are fixedly connected with flank panel (4), and flank panel (4) is provided with the roller (3) be placed in chute (2); The below of chute (2) is provided with the spring hydraulic lever apparatus (1) of several diverse location, and the push rod top of spring hydraulic lever apparatus (1) is fixedly connected with one piece can the plate (7) of load side aerofoil plate (4) and roller (3).The present invention, by changing the torque arm length of counterbalanced weight, increases balancing torque when heavy duty, reduces tower body torque load time unloaded, thus increases the safety of hoisting crane and the use alerting ability in full load interval, greatly reduces tower body load, increases the service life.
Description
Technical field:
The present invention relates to tower crane accessory technical field, specifically a kind of counterbalanced weight for tower crane moves and positioner.
Background technology:
Along with the fast development of China's economic construction, tower crane application is more and more extensive, when hoisting crane is unloaded, bear unnecessary equilibrium arm moment, a lot of moments of torsion and bending load can be born when load, counterbalanced weight is irremovable, cause the moment of crane arm and equilibrium arm unadjustable, hoisting crane is caused to be subject to much unnecessary moment, the tower body meeting run-off the straight when load exceedes tolerance range, tower crane entirety is caused to topple over or rupture, cause a serious accident, therefore the device that a kind of adjustable and balancing is heavy is badly in need of, to improve stability and safety.
Summary of the invention:
Technical matters to be solved by this invention is to provide a kind of counterbalanced weight for tower crane and moves and positioner, heavily increases the arm of force by shifting balance, reduces the arm of force, the safety and stability of equipment is improved when lifting by crane light object.
The present invention solves the problems of the technologies described above with following technical scheme:
A kind of counterbalanced weight for tower crane of the present invention moves and positioner, and the rope comprising winch 8, two winchs 8 that two are arranged on hoisting crane connects the two ends, left and right of counterbalanced weight 5 respectively, makes counterbalanced weight can sway; The steelframe 6 of hoisting crane is provided with two symmetrically arranged chutes 2, and the both sides, front and back of counterbalanced weight are fixedly connected with flank panel 4, and flank panel 4 is provided with the roller 3 be placed in chute 2; The below of chute 2 is provided with the spring hydraulic lever apparatus 1 of several diverse location, and the push rod top of spring hydraulic lever apparatus 1 is fixedly connected with one piece can the plate 7 of load side aerofoil plate 4 and roller 3.
Two rollers are installed below the flank panel 4 of counterbalanced weight both sides of the present invention respectively; The width of described plate 7 is slightly larger than the width of flank panel 4.
Apparatus of the present invention are by shifting balance weight, change the torque arm length of counterbalanced weight, and the scope controlling its arm of force is blocked at ad-hoc location, the unnecessary moment of equilibrium arm is reduced when zero load, can increase counterbalanced weight weight when load but by the heavy position of adjustment, the load be carried on hoisting crane not increased, therefore when lifting by crane heavier object, shifting balance heavily increases the arm of force, the arm of force is reduced, to improve stability and the safety of equipment when lifting by crane light object.

In figure: spring hydraulic lever apparatus 1, chute 2, roller 3, flank panel 4, counterbalanced weight 5, steelframe 6, plate 7, winch 8.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As depicted in figs. 1 and 2, be provided with two symmetrically arranged chutes 2 in the steelframe 6 of hoisting crane, the both sides, front and back of counterbalanced weight 5 weld one piece of flank panel 4 respectively, and the below of flank panel 4 is provided with the roller 3 be placed in chute 2.The below of chute 2 is provided with the spring hydraulic lever apparatus 1 of several diverse location, and spring hydraulic lever apparatus 1 is fixed on steelframe 6, as shown in Figure 3.The push rod top of spring hydraulic lever apparatus 1 is fixedly connected with one piece can the plate 7 of load side aerofoil plate 4, the width of plate 7 is slightly larger than the width of flank panel 4, plate 7 can rise to the position maintained an equal level with chute 2 by spring hydraulic lever apparatus 1, also can drop to the position lower than chute 2, as shown in Figure 4.
As shown in Figure 5, the rope being arranged on two winchs 8 on hoisting crane steelframe 6 connects the two ends, left and right of counterbalanced weight 5 respectively, and counterbalanced weight 5 is horizontally slipped along chute 2 by flank panel 4 and roller 3.
Principle of work of the present invention is as follows:
When winch 8 rope shrinks, counterbalanced weight 5 is slided on chute 2 by flank panel 4 and roller 3, decline by control setup controlling spring hydraulic stem device 1 when sliding into the position of plate 7, and drive plate 7 to decline, flank panel 4 is then blocked by chute 2, roller 3 sink, and makes counterbalanced weight 5 by screens in that specific position, as shown in Figure 3.When not needing in this position by card, being risen by control setup controlling spring hydraulic stem device 1, driving plate 7 to rise to the position maintained an equal level with chute 2, flank panel 4 and roller 3 are passed through smoothly; By pull counterbalanced weight 5 movement that driven equilibrium weighs 5 of winch 8 rope at two ends, left and right.
Use apparatus of the present invention, the unnecessary moment of equilibrium arm can be reduced when zero load, counterbalanced weight weight can be increased when load but by the heavy position of adjustment, the load be carried on hoisting crane not increased, thus improve the stability and safety run, and use flexibly, can service life of extension device.
