Abstract
The utility model discloses a gantry crane for installing large equipment, which relates to a gantry crane, and aims to solve the technical problem of high operation difficulty for installing large equipment by large crawler cranes. Four support columns are divided into two groups; the lower ends of each two support columns are connected with lower cross beams, and the upper ends of each two support columns are connected with main beams; two upper cross beams are arranged between the two main beams; the two lower cross beams are respectively connected with an operating mechanism; the two operating mechanisms can operate on two self-contained tracks; four hoisting mechanisms are divided into two groups; each hoisting mechanism consists of a winch, a lower pulley group, an upper pulley group and steel wire ropes; the four hoisting mechanisms are fixed on the two lower cross beams; the four upper pulley groups are fixed on the two upper cross beams; the winches, the lower pulley groups and the upper pulley groups are connected through the steel wire ropes; and the four lower pulley groups and the lifted equipment form four-lifting-point connection. The gantry crane is used for installing the large equipment, and has the advantages of flexibility in lifting, descending and operation, and convenience in equipment connection, dismounting and transportation.
Description
Technical field
The utility model relates to transfer crane, particularly a kind of gauntry crane for main equipment is installed.
Background technology
At present, large caterpillar is used in the installation of large-scale equipment in factory building (as compression machine) usually.In order to satisfy the lifting lifting altitude, sometimes need remove the factory building roof, not only dismounting difficulty is large, and expense is high, long construction period.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of gauntry crane for main equipment is installed is provided, and solves and uses large caterpillar that the large technical matters of main equipment operation easier is installed.
The utility model is achieved through the following technical solutions:
A kind of gauntry crane for main equipment is installed is characterized in that: described gauntry crane by four door legs, two girders, two entablatrances, two cross sills, two cover operating units, two provide track for oneself and the quadruplet hoisting mechanism forms; Four described door legs are divided into two groups, the lower end of every group two described door legs is connected with described cross sill with bolt, the upper end of every group two described door legs is connected with described girder with bolt, be provided with two entablatrances between two described girders, be connected with described operating unit respectively below two described cross sills, the two described operating units of cover can move two described providing for oneself on track respectively; The quadruplet hoisting mechanism is divided into two groups, every group two cover, the described hoisting mechanism of every cover is comprised of winch, downslide wheels, top sheave group and steel rope, four described winchs are separately fixed on two described cross sills, four described top sheave groups are fixed on respectively on two described entablatrances, by described steel rope, winch, downslide wheels, top sheave group are connected, four described downslide wheels have consisted of four-point lifting with the equipment that hung and have been connected.
The utility model compared with prior art, owing to having adopted four fixed windlass that crane capacity is identical, with steel rope, winch and upper and lower assembly pulley are intertwined, and the top sheave group is fixed on girder with on bolted entablatrance, can move two positions between entablatrance according to the width that is hung equipment, adjust the suspension centre of four Heave Heres apart from L
T, four winchs are switched on simultaneously and can be hoisted and descend object.Because cross sill is provided with operating unit, can realize vertically moving of a machine.The utility model be used for to be installed main equipment (as compression machine), has a machine lifting, decline, flexible operation, equipment connection, disassemble, the advantage of convenient transportation.
Description of drawings
Fig. 1 is structural representation of the present utility model (front view);
The right elevation of Fig. 2 Fig. 1.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, a kind of gauntry crane for main equipment is installed, by four door legs 7, two girders 6, two entablatrances 5, two cross sills 8, two cover operating units 9, two provide track 10 for oneself and the quadruplet hoisting mechanism forms; Four described door legs 7 are divided into two groups, the lower end of every group two described door legs 7 is connected with described cross sill 8 with bolt, the upper end of every group two described door legs 7 is connected with described girder 6 with bolt, be provided with two entablatrances 5 between two described girders 6, be connected with described operating unit 9 respectively below two described cross sills 8, the two described operating units 9 of cover can move two described providing for oneself on track 10 respectively; The quadruplet hoisting mechanism is divided into two groups, every group two cover, the described hoisting mechanism of every cover is comprised of winch 1, downslide wheels 2, top sheave group 3 and steel rope 4, four described winchs 1 are separately fixed on two described cross sills 8, four described top sheave groups 3 are separately fixed on two described entablatrances 5, by described steel rope 4, winch 1, downslide wheels 2, top sheave group 3 are connected, four described downslide wheels 2 have consisted of four-point lifting with the equipment that hung and have been connected.
Select four the identical fixed windlass 1 of crane capacity, top sheave group 3 and downslide wheels 2 according to the multiplying power of hoisting capacity and assembly pulley.According to the width that is hung equipment can mobile suspension centre apart from L
TGenerally hung equipment light, L
TBe worth little; Hung equipment heavy, L
TValue is large.The span L of gauntry crane
KAlso to determine according to the width that is hung equipment.The height of door leg 7 is determined according to hanging device height.Cross sill 8 all is connected with bolt with entablatrance 5 with door leg 7, girder 6 with operating unit 9, cross sill 8, and mounting and dismounting are convenient.After four groups of downslide wheels 2 and the equipment that hung are fixing, start simultaneously four winchs 1, will be hung equipment lifting liftoff, gauntry crane is being provided operation on track 10 for oneself, the place in place equipment decline of arrival equipment, installation in place.Otherwise the process of disassembling.The utlity model has lifting, operation, lower degradation function, satisfied the requirement that the equipment lifting is installed.The structure each several part all adopts Bolt to position to connect, and conveniently installs, disassembles, transports.
