Description
The utility model belongs to the special purpose crane that is used for the building site, particularly a kind of lifting appliance of building network frame house cap.
The network frame house cap structure of building, because of its good integrity, shock resistance is strong, building flexible arrangement, short construction period, and extensive use.Its construction method of installation has installation at high altitude or installation on ground, the whole two big classes that promote, in integral lifting method, again to adopt the whole lifting of mast to be installed as.Present mast lifting appliance mostly is steel pipe dead man and bar capstan or electric winch to be formed, and setting and dismounting mast are not very convenient; When many lifting appliances promoted the rack operation simultaneously, the bar capstan or the electric winch synchronism that promote usefulness were bad, and safety is not high, therefore, all were difficult to satisfy on lifting weight and setting height(from bottom) use for large-size net rack.The lifting machine that Chinese patent " ZL94216605.1 uses hoisting machine more " provides a kind of building site to use is made up of track, A-frame, hoist engine, simple structure, but be difficult to satisfied lifting to rack integral body.
The purpose of this utility model is, designs and produces a kind of rack integral lifting apparatus, adopts the light-duty guide rail bracket of uniform section cancelled structure, connects with burnished bolt between the standard knot, and the middle part standard knot is provided with the hinge ear of removing guide rail bracket self usefulness; Hang narrow type suspension bracket by head sheave and assembly pulley, guide wheel device and safety device are set on suspension bracket,, safety, finish the lifting installation exercise of whole rack synchronously, reposefully so that during many lifting appliance synchronization jobs; And can from mounted whole rack below guide rail bracket be folded dismounting easily.
A kind of rack integral lifting apparatus of the present utility model, form by base, guide rail bracket, suspension bracket, guide wheel device, safety device, assembly pulley, wire rope, it is characterized in that, base is welded into the rectangle housing by channel-section steel, is provided with four hinged-supports of guide rail bracket and the directive wheel support of wire rope on housing; Guide rail bracket is spliced to form by standard knot, and standard knot is made of the stull of welding angle steel, brace and gusset between four column guide rail steel pipes, and the upper and lower end of column guide rail steel pipe adopts the socket form; The standard knot column steel pipe outside, bottom is provided with 4 hinge ears with the hinged usefulness of base, and the middle part standard knot is provided with two groups of hinge ears of dismounting usefulness in column steel tube end part one side; Be provided with the pulley frame that two pulleys are formed on the guide rail bracket top, standard knot side, top is provided with the block pulley group, below the movable pulley of block pulley group, by narrow type suspension bracket suspension hook suspension strap safety device and guide wheel device, that be used to promote whole rack.
The rectangular framework of narrow type suspension bracket, lower transverse beam are provided with two hangers that promote whole net frame, and crossbeam one side is provided with the guide wheel that slides on guide rail bracket; Guide wheel device is welded into right angle frame by shaped steel, the inboard be provided with the clamping guide rail, the mutually perpendicular guide wheel of axis; Safety device adopts RHS-1 type hoist with lever augmented friction catch formula safety tongs, excites breaking rope protecting and speed control to excite the hypervelocity slide to fall protection two by the power control and partly forms; Assembly pulley is made up of 4 fixed pulleys and 5 movable pulley.
Using method of the present utility model is; Adopt many lifting appliances to promote the method for whole rack synchronously.At engineering site, assemble lifting appliance on the spot, the standard knot of guide rail bracket is connected with burnished bolt, two groups of hinge ears of middle part standard knot connect with junction plate, and pulley frame, block pulley group all can install, and are that narrow type suspension bracket is not assembled earlier.When setting up lifting appliance, need to utilize auxiliary mast, near base, erect auxiliary mast; Two hinges of the guide rail bracket coxopodite ear that assembles on the ground is hinged on the hinged-support of base, wire rope and the fixed pulley of auxiliary mast upper end, the leading block of lower end with block pulley group on the guide rail bracket are connected in series on the hoist engine, start hoist engine, guide rail bracket is cocked with rotary process, be hinged on the hinged-support in addition two hinge ears of guide rail bracket coxopodite fixing with bolt then; After having erect guide rail bracket, the tensioning cable wind rope; Remove auxiliary mast, install narrow type suspension bracket, finish and set up operation.Assembly network frame on the spot, this moment, guide rail bracket was within the whole rack scope, and therefore, the rack web member that guide rail bracket plants oneself wouldn't be assembled.The operation that promotes whole rack is, the hanger of the narrow type suspension bracket on the guide rail bracket is linked to each other with wire rope with a plurality of nodes of rack lower edge, start hoist engine, can lift by crane whole rack, when removing lifting appliance, because after rack installs, guide rail bracket is in the rack scope, need to support one group of hinge ear place, standard knot top, middle part of guide rail bracket with auxiliary mast, back out the connection burnished bolt between two standard knots in one group of hinge ear place, standard knot below, middle part then, back out two bolts that cut with scissors ears that the guide rail bracket coxopodite is connected with base, with wire rope by another directive wheel support on the base, utilize hoist engine pulling wire rope, guide rail bracket is rotated around middle part standard knot below one group of hinge gudgeon, and guide rail bracket can fall slowly.Auxiliary mast is the rod member that the termination is provided with hinge ear and junction plate, perhaps adopts small-sized door frame to get final product.
The utility model has the advantages that: the lifting tonnage is big, but 30 tons of racks of lifting when 30M is high; The guide rail bracket cross sectional dimensions is little, is fit to the network frame hoisting characteristics; Each standard knot connects with burnished bolt, and single-unit weight is little, is convenient to lift; Standard knot quantity is selected according to sling height, and is flexible; Adopt the top pulley frame, make structure stress reasonable, improve stress condition.Adopt auxiliary mast, the integral erection guide rail bracket, the efficient height, speed is fast; Employing adds the way of cutting with scissors ear between standard knot, guide rail bracket can cut with scissors the gudgeon rotation around coxopodite during dismounting, and it is rapidly convenient to remove; Narrow type suspension bracket installing breaking rope protecting of lifting and hypervelocity are slipped and fallen two cover protective devices, and be safe and reliable; Guide rail bracket set up and remove the auxiliary mast that adopts this device to carry, do power with hoist engine, convenient and swift, safe and reliable.The integral body that is applicable to the network frame house cap of various buildings promotes.
