Building hoist is widely used a kind of vertical transportation machinery in modern architecture construction, is mainly used in the transportation up and down of workmen, building materials and construction equipment.Building hoist has counterweight building hoist and counterweightless building hoist according to there being counterweightless to be divided into.Present stage has that the building hoist of counterweight is low because consuming energy, guide rail bracket reasonable stress, starting current are little, electrical network is impacted to the plurality of advantages such as little, and Occupation coefficient is higher.But it is loaded down with trivial details that the standard knot installation of its guide rail bracket, dismounting are compared with the building hoist of counterweightless, in operation, there are some potential safety hazards.Deficiency for existing, has much designed polytype jack up drilling platform with administrative staff now, has realized building hoist dependence self accessory device and has carried out Assembly &Disassembly.If announcement number in prior art is the patent " S type building hoist jack up drilling platform " of CN2878305Y, its vertical transport function of utilizing elevator basket connects standard knot to transport near jack up drilling platform from ground, do not need extra lifting appliance, safe, reliable, convenient, but its power from liter and lifting is from manual hoist, and workman need to stand on service platform around the work of upright post of elevator surrounding, need to consume human resources, also has potential safety hazard.Notification number is the patent " elevator frame for construction " of CN201228183Y, and it uses hydraulic gear to carry out the lifting of jack up drilling platform, and hydraulic gear exists cost high, to the high disadvantage that requires of installing.Notification number is the patent " construction elevator moves lifting stock " of CN200954969Y, and it exists the parts that have from lift operations process to need occasional combination to install, the disadvantage of operating process trouble.
Utility model content
The disadvantage existing for above-mentioned prior art, the purpose of this utility model is that a kind of building hoist jack up drilling platform lift system will be provided, its power is without relying on manpower, but comes from electric driving mechanism; Cheap; From lift operations process without there being again parts occasional combination to install, the simple and safety of operating process.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of building hoist jack up drilling platform lift system, comprise top standard knot, jack up drilling platform, its main points are, it also comprise be movablely contained in the pulley that fills on movable pulley support on the standard knot of top, movable pulley support, be installed on winch on jack up drilling platform and fixed pulley, steel rope; Steel rope is worn and is walked around pulley, fixed pulley, and one end is fixed and is wound on the rope sheave of winch, and the other end fixedly ties up on jack up drilling platform.
As preferably, two pulleys are equipped with at the described movable pulley support two ends that make progress, and two ends can be inserted in respectively in the hole of column of top standard knot and fix downwards.
As preferably, described movable pulley support upwards one side is equipped with a pulley, and one side can be inserted in the hole of column of top standard knot and fix downwards.
The utility model compared with prior art tool has the following advantages: when supernumerary segment or dismounting, steel rope is worn and walked around pulley, fixed pulley, and one end is fixed and is wound on the rope sheave of winch, and the other end fixedly ties up on jack up drilling platform.Start winch, can realize the lifting of jack up drilling platform, the peace that completes standard knot by the suspender on jack up drilling platform is torn operation open; This kind of jack up drilling platform lift system is simple in structure, and dependable performance is safe; Winch is driven by motor, does not need to use artificial manual hoist; From lift operations process, without there being parts occasional combination to install, operating process is simple and efficiency is high again; Also have its low cost of manufacture, easily promote.
