Abstract
The utility model relates to an elevating rope height limiter for a trolley amplitude varying tower crane, which is positioned on a tower machine arm bracket, wherein, one side of which is provided with a barrel-shaped supporting seat, and an elastic body is arranged in the supporting seat. The outer end of the elastic body is connected with an elastic body guide seat which is connected with an L-shaped shaft, and the end part of the L-shaped shaft is arranged under the tower machine bracket. When the L-shaped shaft is rotated, the L-shaped shaft can drive the elastic body guide seat to cause the elastic body to be compressed, the elastic body releases to cause the L-shaped shaft to reset, and the shaft end part is sheathed with a rope supporting roller. The limiter has simple structure, no power need, reliable operation and convenient installation. The utility model can cause the weight of a suspension hook to reduce by 50%, the elevating sag is limited, the self weight of the suspension hook is lightened, and the effective elevating capacity is improved.
Description
The utility model relates to a kind of crane hoisting rope sag killer.
Trolley-jib tower crane at work, especially in empty hook luffing or lifting process, the weight of suspension hook and boom length and raising line deadweight relation are very big, the long more suspension hook that requires of jib is heavy more, otherwise the raising line sag of chain is excessive, causes the lifting mechanism disorder cable, can cause suspension hook to descend when serious, and increasing the weight of of suspension hook just means the decline of effective hoisting capacity.General tower machine does not have raising line sag killer, depends merely on to increase the weight of the suspension hook deadweight and solve problem.
The purpose of this utility model aims to provide a kind of simple in structure, unpowered, reliable operation, trolley-jib tower crane raising line sag killer easy for installation, and restriction raising line sag alleviates the suspension hook deadweight, improves effective hoisting capacity.
The purpose of this utility model is achieved in that trolley-jib tower crane raising line sag killer is positioned on the arm frame of tower crane, it is characterized in that: one tubular bearing is arranged in arm frame of tower crane one side, elastic body is housed in the bearing, the elastic body outer end is connected with the elastic body guide bracket, the elastic body guide bracket is connected with L shaped special-shaped axis, and L shaped special-shaped axis end can drive the elastic body guide bracket and make the elastic body compression under arm frame of tower crane during rotation, elastic body discharges L shaped special-shaped axis is resetted, and shaft end is with holder rope roller.
Above-mentioned elastic body be compression spring, torsion spring, reed or can energy-absorbing release can polyurethane material.
Working process of the present utility model: trolley-jib tower crane raising line sag killer is installed on the elevator boom rack mid point, when crane carriage 3 runs to raising line sag killer place, special-shaped axis 7 bears against down at crane carriage, around angle of vertical shaft turn-off, allow crane carriage 3 pass through, special-shaped axis 7 pushes elastic body guide brackets 6 simultaneously, make elastic body 5 compress energy storage, after crane carriage 3 passed through, special-shaped axle 7 suffered squeese pressures disappeared, and the accumulation of energy of elastic body 5 discharges, promote elastic body guide bracket 6, and extruding special-shaped axis 7 goes back to original position, just in time holds derrick line, and the sag of derrick line is limited within the specific limits.On special-shaped axle 7, rotatable holder rope is housed and rolls 8, be not subjected to additional wear when making derrick line work.
Advantage of the present utility model: simple in structure, need not power, reliable operation, easy for installation, can make suspension hook weight saving 50% after the installation.Can limit the raising line sag, improve effective hoisting capacity.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the scheme of installation of the utility model embodiment.
Fig. 2 is Figure 1A-A section-drawing.
As shown in Figure 1, this killer is positioned on the arm frame of tower crane 1.As Fig. 2: one tubular bearing 4 is arranged in arm frame of tower crane 1 one sides, the elastic body 5 of compressed spring type is housed in the bearing 4, elastic body 5 outer ends are with elastic body guide bracket 6, the lower end of elastic body guide bracket 6 be connected with the end under arm frame of tower crane, can promote the L shaped special-shaped axis 7 that the elastic body guide bracket makes elastic body compression and released movement.Shaft end is with holder rope roller 8.
Claims (2)
1, a kind of trolley-jib tower crane raising line sag killer, it is positioned on the arm frame of tower crane, it is characterized in that: one tubular bearing is arranged in arm frame of tower crane one side, elastic body is housed in the bearing, and the elastic body outer end is connected with the elastic body guide bracket, and the elastic body guide bracket is connected with L shaped special-shaped axis, L shaped special-shaped axis end is under arm frame of tower crane, can drive the elastic body guide bracket during rotation and make the elastic body compression, elastic body discharges L shaped special-shaped axis is resetted, and shaft end is with holder rope roller.
2, trolley-jib tower crane raising line sag killer according to claim 1, described elastic body be compression spring, torsion spring, reed or can energy-absorbing release can polyurethane material.
