Abstract
The utility model relates to a crane, specifically a tower type crane vibrating amplitude small car tight cable device which consists of a tight cable wheel, a pawl and a supporting body; the supporting body supports the tight cable wheel and the pawl; the pawl is connected with the tight cable wheel, which prevents a steel wire cable from becoming loose. The utility model has the advantages of reasonable design, simple structure, convenient use, safety, reliability and low cost; the utility model can regulate the tightness of the steel wire cable, prevents the steel wire cable from becoming loose, effectively makes the vibrating amplitude to prevent the steel wire cable from breaking off, to keep a clip board level and not to interfere the operation of a lower boom web rod, guarantees the vibrating amplitude to operate along a rail normally and is suitable for a tower type crane.
Description
Technical field:
The utility model relates to hoisting crane, specifically a kind of tower crane amplitude variation trolley tight rope device.
Background technology:
At present, crane amplitude variation trolley does not have escapement, and is directly fixing with steel rope, occurs amplitude variation trolley clamp and the collision of crane arm lower edge web member after steel rope is lax easily, thereby dolly can't normally be moved and the lax wearing and tearing of steel rope, causes potential safety hazard.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provides a kind of reasonable in design, simple in structure, easy to use, effective, safe, firm tower crane amplitude variation trolley tight rope device.
The technical scheme that its technical matters that solves the utility model adopts is a kind of tower crane amplitude variation trolley tight rope device, and it is made up of bearing up pulley, ratchet, supporting mass, and supporting mass supports bearing up pulley and ratchet, and ratchet and bearing up pulley join, and prevents that steel rope is lax.
The utility model is reasonable in design, simple in structure, can adjust the elasticity of steel rope, prevent that steel rope is lax, makes amplitude variation trolley anti-break rope clamp maintenance level effectively, do not interfere with crane arm lower edge web member, guaranteed that amplitude variation trolley normally moves along track, easy to use, safety, reliably, cost is low.
Description of drawings:
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
Among Fig. 1 and Fig. 2: 1, bearing up pulley, 2, ratchet, 3, supporting mass, 4, the tight rope axle.
From Fig. 1 and Fig. 2 as can be seen, a kind of tower crane amplitude variation trolley tight rope device, it is made up of bearing up pulley 1, ratchet 2, supporting mass 3.Wherein, supporting mass 3 plays a part to support and fixedly bearing up pulley 1 and ratchet 2.Ratchet 2 joins with bearing up pulley 1.Adjust the elasticity of steel rope by tight rope axle 4, make it to keep tensioning state.Ratchet 2 can prevent effectively that steel rope is lax, makes amplitude variation trolley anti-break rope clamp maintenance level, does not interfere with crane arm lower edge web member, has guaranteed that amplitude variation trolley normally moves along track.
The utility model is reasonable in design, simple in structure, can adjust the elasticity of steel rope, prevent that steel rope is lax, makes amplitude variation trolley anti-break rope clamp maintenance level effectively, do not interfere with crane arm lower edge web member, guaranteed that amplitude variation trolley normally moves along track, easy to use, safety, reliably, cost is low.Be suitable for using on the tower crane.
Claims (1)
1. tower crane amplitude variation trolley tight rope device is characterized in that it is made up of bearing up pulley, ratchet, supporting mass, and supporting mass supports bearing up pulley and ratchet, and ratchet and bearing up pulley join, and prevent that steel rope from relaxing.
