Abstract
The utility model provides a rope tightener for a revolving drum of a tower crane trolley, which comprises a left support plate, a right support plate and the revolving drum arranged between the two support plates, wherein a rotary shaft is arranged in the middle of the revolving drum, and two ends of the rotary shaft are respectively fixed onto a left fixed plate and a right fixed plate. The rope tightener is characterized in that an elongated through hole which extends in the vertical direction is arranged on the fixed plate, a pin shaft is arranged in the elongated through hole, the outer edges of the support plates are provided with through holes which extend towards the rotating direction of the revolving drum when a rope is tightened, and the pin shaft is abutted against the outer edge of the support plates. The utility model has the advantages that the installation time is shortened and the safety factors are improved.
Description
Technical field
The utility model relates to a kind of tower crane dolly rotating cylinder boomer, is used for tight steel rope.
Background technology
As shown in Figure 1, be traditional tower crane dolly rotating cylinder boomer front view, Fig. 2 is its lateral plan, two support plates 2 and be located at two rotating cylinders 1 between the support plate 2 about described traditional tower crane dolly rotating cylinder boomer comprises, rotating cylinder 1 middle part is provided with rotating shaft, and on two adapter plates 4, support plate 2 outer rims were provided with circular port about the two ends of rotating shaft were separately fixed at, bearing pin 3 passes the circular port of adapter plate 4 and support plate 2 outer rims, with rotating cylinder 1 stationkeeping.During tight rope, need extract bearing pin 3 earlier and rotate rotating cylinder 1 tight rope again.If use the tower crane dolly rotating cylinder boomer of said structure, when installing, the erector must operate simultaneously with two people, and a people extracts bearing pin, and a people rotates the rotating cylinder tight rope, not too makes things convenient for but also the consumption set-up time during use.
Summary of the invention
This practical purpose provide a kind of can the one man operation and have than high safety factor tower crane dolly rotating cylinder boomer.
In order to achieve the above object, the utility model provides a kind of tower crane dolly rotating cylinder boomer, two support plates and be located at two rotating cylinders between the support plate about comprising, rotating cylinder middle part is provided with rotating shaft, on two adapter plates, it is characterized in that about the two ends of rotating shaft are separately fixed at, adapter plate is provided with the strip shape through hole that vertically extends, bearing pin is located in the strip shape through hole, the through hole that the rotation direction of rotating cylinder was extended when the outer rim of support plate was provided with along tight rope, and bearing pin is near the outer rim of support plate.
The utility model has the advantages that and shortened the set-up time, improved safety factor.
Description of drawings
Fig. 1 is traditional tower crane dolly rotating cylinder boomer front view;
Fig. 2 is traditional tower crane dolly rotating cylinder boomer lateral plan;
Fig. 3 is a tower crane dolly rotating cylinder boomer front view of the present utility model;
Fig. 4 is a tower crane dolly rotating cylinder boomer lateral plan of the present utility model.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 3, be tower crane dolly rotating cylinder boomer front view of the present utility model, two support plates 5 and be located at two rotating cylinders 1 between the support plate 5 about described tower crane dolly rotating cylinder boomer comprises, rotating cylinder 1 middle part is provided with rotating shaft, about the two ends of rotating shaft are separately fixed on two adapter plates 4.
As shown in Figure 4, be tower crane dolly rotating cylinder boomer lateral plan of the present utility model, adapter plate 4 is provided with the strip shape through hole 6 that vertically extends, bearing pin 3 is located in the strip shape through hole 6, the through hole 7 that rotating cylinder 1 rotation direction was extended when the outer rim of support plate 5 was provided with along tight rope, bearing pin 3 is near the outer rim of support plate 5.During tight rope, rotating cylinder 1 rotates along clockwise direction, and bearing pin 3 fluctuates in strip shape through hole 6 near the outer rim of support plate 5, and when the tight rope operation stopped, rotating cylinder 1 rotated earlier in the counterclockwise direction, and bearing pin 3 snaps in the through hole 7, makes rotating cylinder 1 stop operating.In the whole operation process, do not need to extract bearing pin 3, shortened the set-up time so greatly, improved safety factor.
