Abstract
The utility model relates to a ward-off rope device of a telescopic boom crane, which relates to the hoisting machinery and solves the problem that the superlift steel wire rope in the prior art is in danger of sliding. The ward-off rope device comprises a supporting base fixed on a superlift device, and a ward-off rope roller connected with the supporting base. The ward-off rope device of the telescopic boom crane is characterized in that both ends of the ward-off rope roller are fixed on two sliding frames, respectively, wherein one end of one sliding frame is connected with an oil rod of a hydraulic oil cylinder. The cylinder body of the hydraulic oil cylinder is fixed with the supporting base. The two sliding frames are matched with a guide rod fixed on the superlift device. The hydraulic oil cylinder is connected with an oil path system. The superlift device is provided with limiting bases that position the sliding frames. The ward-off rope device for the telescopic boom crane has the advantages of stable in sliding, accurate in positioning and strong in practicality, can prevent the steel wire rope from sliding effectively and is simple to operate.
Description
Technical field
The utility model relates to elevator machinery, particularly a kind of super lifting device of telescopic arm crane.
Background technology
Like Fig. 1, shown in 2, when telescopic arm crane was worked under super lifting working condition, super lifting device 2 was vertical with telescopic boom 1, and two arms of super lifting device 2 open a certain angle a simultaneously, have surpassed steel rope 3 in tension.End at telescopic arm crane super lifting device 2 is installed ward off rope device 4.
As shown in Figure 3, existing ward off rope device 4 is made up of with the retaining rope roller 4-2 that is fixed on the support 4-1 the support 4-1 that is fixed on the super lifting device 2.This is simple in structure, and retaining rope roller 4-2 is fixed on ad-hoc location, can not slide.When under super lifting working condition, working; Surpass steel rope 3 and be in the tensioning strained condition; Owing to keep off rope roller 4-2 stationkeeping, do not fix and surpassed the rope stretching position of steel rope 3 on super lifting device, there is the gap between the steel rope 3 if keep off rope roller 4-2 this moment and surpassed; Then retaining rope roller 4-2 is inoperative, and having surpassed steel rope 3 has the danger of taking off groove.
The utility model content
The utility model provides a kind of ward off rope device of telescopic arm crane in order to overcome the shortcoming of above-mentioned prior art, solves the ward off rope device of existing telescopic arm crane, and it has surpassed steel rope has the dangerous problem of groove of taking off.
The utility model is to adopt following measure to realize:
A kind of ward off rope device of telescopic arm crane; Comprise: with telescopic boom super lifting device connected vertically, surpassed steel rope, be installed in the terminal ward off rope device of said super lifting device with said super lifting device bonded assembly; Said ward off rope device comprises: be fixed on the bearing on the super lifting device; With said bearing bonded assembly retaining rope roller, it is characterized in that: the two ends of said retaining rope roller are separately fixed on two sliding racks, and an end of one of them sliding rack links to each other with the beam hanger of hydraulic ram; The cylinder body of said hydraulic ram and said bearing are fixed; Two said sliding racks be fixed on the pilot bar bearing fit on the said super lifting device, said hydraulic ram links to each other with oil piping system, said super lifting device is provided with the limit base that said sliding rack is located.
The utility model compared with prior art; The ward off rope device that one cover is made up of bearing, retaining rope roller, sliding rack, hydraulic ram, limit base and oil piping system is set on the telescopic arm crane super lifting device; Drive retaining rope roller through hydraulic ram, with having surpassed the position that the steel rope retaining is being set.The utility model hydraulic-driven is slided steadily, and accurate positioning can prevent that effectively steel rope from taking off groove according to the state real-time positioning of steel rope on super lifting device in oil cylinder stroke.This device is simple to operate, and is practical.
Description of drawings
Fig. 1 is the installation site scheme drawing of ward off rope device on telescopic arm crane;
Fig. 2 is the lateral plan of Fig. 1;
Fig. 3 is the enlarged diagram of existing ward off rope device on super lifting device;
Fig. 4 is the structural representation of the utility model.
The utility model is elaborated through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 4; A kind of ward off rope device of telescopic arm crane; Comprise: with telescopic boom 1 super lifting device 2 connected vertically, surpassed steel rope 3, be installed in the ward off rope device 4 of said super lifting device 2 ends with said super lifting device 2 bonded assemblys; Said ward off rope device 4 comprises: be fixed on the bearing 4-1 on the super lifting device 2, with said bearing 4-1 bonded assembly retaining rope roller 4-2; The two ends of said retaining rope roller 4-2 are separately fixed on two sliding rack 4-3; The end of one of them sliding rack 4-3 links to each other with the beam hanger of hydraulic ram 4-5; The cylinder body of said hydraulic ram 4-5 and said bearing 4-1 fix; Two said sliding rack 4-3 be fixed on the pilot bar 4-4 bearing fit on the said super lifting device 2, said hydraulic ram 4-5 links to each other with oil piping system 4-7, said super lifting device 2 is provided with the limit base 4-6 that said sliding rack 4-3 is located.
The working process of the utility model:
The first step: before super lifting device 2 launches, in the beam hanger chamber of hydraulic ram 4-5 low pressure oil is arranged, make oil cylinder be in full reduced state.Second step: as shown in Figure 1, super lifting device 2 launches and 1 one-tenth 90 ° of telescopic booms, and when two arms of super lifting device 2 launched 10 ° respectively, tensioning had surpassed steel rope 3, and hydraulic ram 4-5 gets into pressure oil, and oil cylinder promotes sliding rack 4-3 slides its drive retaining rope roller 4-2.When retaining rope roller 4-2 slide in the tensioning state surpass the position of steel rope 3 time, the by pass valve effect among the oil piping system 4-7, oil cylinder stops to move also locked.The 3rd step: telescopic arm crane work finishes, and hydraulic ram 4-5 oil return drives sliding rack 4-3 and slides into initial position with retaining rope roller 4-2, and oil cylinder quits work, and limit base 4-6 makes sliding rack 4-3 be positioned at desired location.
