Abstract
The invention relates to a multifunctional suspension hook counterweight apparatus, which comprises an arm head pulley rack, a counterweight block and a suspension hook, the lower part of the arm head pulley rack is connected to the counterweight block through a steel wire rope, the counterweight block is divided into a front part and a rear part, a rope end fixed pressure sleeve used for fixing the steel wire rope is provided between the front counterweight block and the upper part of the rear counterweight block, two pulling plates are provided between the front counterweight block and the middle and lower part of the rear counterweight block, the upper portion of the pulling plate is connected to a heavy type sleeve ring with a connection aperture through a pin shaft, the lower part of the pulling plate exposes out of the counterweight block, and the lower part of the pulling plate is connected to a suspension hook through hinged bolt and nut. The multifunctional suspension hook counterweight apparatus has the advantages of novel structure, concise external form and compact structure, and is suitable for matched cranes of offshore work platforms and ships, and the security and the technical content of the cranes can be enhanced.
Description
Technical field
The present invention relates to a kind of Multifunctional hanging hook counter weight device and relate to lifting parts, particularly the lifting parts of the 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, weight-lifting equipment is also proposed to upgrade higher requirement simultaneously.Due to the structure particularity of offshore work platform, when hoisting crane is parked, suspension hook often overhangs beyond deck, cannot place above deck, can produce very large impact to arm member at sea under job platform towing condition; In addition, important production facilities as offshore work platform, to the various safetys of equipment, be also exigent, for suspension hook, if just require spacingly at work malfunctioningly can not damage actuating unit and crane steel structure, if the clump weight that utilizes suspension hook itself just to need, can overcome the above problems again, just can reduce equipment cost, improve the technology content of safety and hoisting crane, the competitive power of lift crane product.The suspension hook of offshore work platform hoisting crane suspends mostly, and also infinite place based Cb Failure Protection, so safety is poor.
Summary of the invention
The object of the invention is, in order to overcome above deficiency, provides a kind of Multifunctional hanging hook counter weight device, is meeting on suspension hook counterweight basic function, has solved again suspension hook and has parked and the spacing malfunctioning problem that also can not damage actuating unit and crane steel structure.
Object of the present invention is achieved through the following technical solutions: a kind of Multifunctional hanging 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, between anterior clump weight and the top of rear portion clump weight, be provided with for the fixing gland of the end of fixing described steel rope, between anterior clump weight and the middle and lower part of rear portion clump weight, be provided with two arm-ties, the top of arm-tie is connected with the heavy collar with connecting bore by bearing pin, clump weight is exposed in the bottom of arm-tie, the bottom of arm-tie is connected with suspension hook by articulation bolt and nut.
Further improvement of the present invention is: anterior clump weight and rear portion clump weight are connected and fixed by four retaining thread pairs.
The present invention compared with prior art has the following advantages: the present invention links together clump weight, steel rope and suspension hook by the heavy collar, bearing pin, arm-tie, articulation bolt and nut, suspension hook load is without through clump weight, but directly by articulation bolt, arm-tie, bearing pin and the heavy collar by force transmission to steel rope; When clump weight arrives arm head pulley yoke stand, the suffered application force of clump weight is directly delivered on steel rope by bearing pin and the heavy collar, without process arm-tie and suspension hook; Above clump weight, be flat, rounding on limit, the stressed and guiding while being convenient to clump weight arrival arm head pulley yoke stand is parked; The mounting hole that clump weight is connected with bearing pin is blind hole, and after whole device installs, bearing pin is ensconced inner, and service free is safeguarded; Clump weight is divided into symmetrical halves cylinder, by four groups of screw thread pairs, is connected and fixed, and convenient that bearing pin and heavy collar plant is inner, service free is safeguarded; The present invention has the advantages such as novel structure, external form are succinct, compact conformation, is applicable to being applied on the supporting hoisting crane such as offshore work platform, boats and ships, can improve the technology content of safety and hoisting crane, is a kind of hoisting crane accessory with broad prospect of application.
