Description
Technical field:
The utility model relates to a kind of multi-functional suspension hook counter weight device and relates to the lifting parts, particularly the lifting parts of Offshore Units such as offshore wind farm erecting stage, drilling platform, service platform and boats and ships configuration.
Background technology:
At present, along with the fast development of offshore wind farm and oil production industry, the offshore work platform demand of using hoisting crane to carry out operation and maintenance increases day by day, simultaneously weight-lifting equipment is also proposed to upgrade higher requirement.Because the structure particularity of offshore work platform, suspension hook often overhang beyond the deck when hoisting crane was parked, and can't place above deck, and at sea the job platform towing condition can produce very big impact to the arm member down; In addition, important production facilities as offshore work platform, various safetys to equipment also are exigent, for suspension hook, spacingly at work malfunctioningly can not damage actuating unit and crane steel structure, the clump weight that if can utilize suspension hook itself just to need if just require, can overcome the above problems again, just can reduce equipment cost, improve the technology content of safety and hoisting crane, upgrade the heavy-duty machine competitiveness of product.The suspension hook of offshore work platform hoisting crane suspends mostly, and also infinite place failure protection device is so safety is relatively poor.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, a kind of multi-functional suspension hook counter weight device to be provided, satisfying on the suspension hook counterweight basic function, having solved suspension hook again and parked and the spacing malfunctioning problem that also can not damage actuating unit and crane steel structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of multi-functional suspension hook counter weight device, comprise arm head pulley yoke, clump weight and suspension hook, the below of arm head pulley yoke is connected with described clump weight by steel rope, clump weight is divided into front and rear, be provided with the fixing gland of end that is used for fixing described steel rope between the top of anterior clump weight and rear portion clump weight, be provided with two arm-ties between the middle and lower part of anterior clump weight and rear portion clump weight, the top of arm-tie is connected with the heavy collar of band connecting bore by bearing pin, clump weight is exposed in the bottom of arm-tie, and the bottom of arm-tie is connected with suspension hook by articulation bolt and nut.
Further improvement of the utility model is: anterior clump weight and rear portion clump weight are connected and fixed by four retaining thread pairs.
The utility model compared with prior art has the following advantages: the utility model links together clump weight, steel rope and suspension hook by the heavy collar, bearing pin, arm-tie, articulation bolt and nut, the suspension hook load need not through clump weight, but directly by articulation bolt, arm-tie, bearing pin and the heavy collar with force transmission to steel rope; When clump weight arrived arm head pulley yoke stand, the suffered application force of clump weight was directly delivered on the steel rope by the bearing pin and the heavy collar, need not through arm-tie and suspension hook; Be flat above the clump weight, rounding on the limit, the stressed and guiding when being convenient to clump weight arrival arm head pulley yoke stand is parked; Clump weight and bearing pin bonded assembly mounting hole are blind holes, and after whole device installed, bearing pin was ensconced inner, and service free is safeguarded; Clump weight is divided into the symmetrical halves cylinder, is connected and fixed by four groups of screw thread pairs, and convenient that bearing pin and heavy collar plant is inner, service free is safeguarded; The utlity model has advantages such as novel structure, external form are succinct, compact conformation, be fit to be applied on the supporting hoisting crane such as offshore work platform, boats and ships, can improve the technology content of safety and hoisting crane, be a kind of hoisting crane accessory with broad prospect of application.
