Description

Lifting herringbone lifting mast under the particular surroundings of high-altitude
Technical field
The utility model relates to lifting herringbone lifting mast under the particular surroundings of a kind of high-altitude.
Background technology
In the project of building the new television mast in Guangzhou, in carrying out antenna decline installation project, need to use to descend and use pumping source, equipment such as hydraulic ram, and since the hydraulic efficiency equipment used of decline antenna need install at 529 meters platform places, existing 3t fixedly loop wheel machine only can use pumping source with descending, equipment handlings to 454 such as hydraulic ram meter flat-bed height, but remaining 74 meters just other means of needs dependence carried.Because weights of equipment such as pumping source, hydraulic ram are heavier, can't directly use the manpower transport, therefore must the installation place be arrived in its handling with weight-lifting equipment, because it is the service platform of this decline is positioned at 529 meters platform places of new television mast, Guangzhou, highly quite high.Ground rigging can't winch to descending device this height.Therefore just need need set up lifting mast at 550 meters platform places and come handling decline pumping source, equipment such as hydraulic ram, but because the restriction of height, so can help the installation of lifting mast without any weight-lifting equipment, thereby lifting mast also can't integral installation, need to remove to 550 meters platform places, assemble in the high-altitude with the manpower segmentation.Because have only manpower to rely on, so single weight can't surpass 50kg.Because engineering is special, the new television mast antenna part in Guangzhou is a box-structure, and lifting mast is again interim weight-lifting equipment, so welding that can not be any with generation at the bottom of the tower again.This installation to mast has brought inconvenience very, the new television mast antenna part in Guangzhou horizontal section is to diminish gradually from the bottom up in addition, so lifting mast can not only only be considered a function of lifting height, the function that luffing also need be arranged, so lifting mast need have 6 meters effective radius at least, could guarantee like this at 454 meters platform place handling members.As adopt common lifting mast can't finish the handling task, therefore demanding designing new lifting mast urgently solves the problems referred to above.
Summary of the invention
The purpose of this utility model is to solve existing lifting mast can't finish the problem that the equipment handling is carried out on new television mast top in Guangzhou, and lifting herringbone lifting mast under the particular surroundings of a kind of high-altitude is provided.The utility model designs lifting herringbone lifting mast under the particular surroundings of a kind of high-altitude, it is characterized in that: the herringbone lifting mast is made up of two tubes and a horizon bar, the head captive joint of two tubes, be fixedly connected with the head otic placode at head, end at two tubes is fixedly connected with the afterbody otic placode, two tubes is made of some pipe joint spare bolt togethers, the afterbody otic placode of two tubes end is captiveed joint with pivot pin with the beam of embracing in the antenna box girder with variable cross section place, on the otic placode of head, gin wheel is installed, at the pipe rear portion another pulley is installed, be wound with hoist rope on gin wheel and another pulley, the hoist rope top is connected with shackle, the hoist rope rear portion connects by being located at following winch, on the antenna case beam on herringbone lifting mast top, be connected with a fixed pulley, antenna box girder with variable cross section place at herringbone lifting mast afterbody otic placode place is provided with a coupling link, on coupling link, be fixedly connected with one and pull cucurbit, the other end of chain block is walked around fixed pulley by steel wire and is captiveed joint with the head of herringbone lifting mast, it is characterized in that: the two tubes of herringbone lifting mast is a φ 219x6070 millimeter, between 2 otic placodes of herringbone lifting mast afterbody at a distance of 1800 millimeters.The utility model has the advantages that the handling that can realize the smallclothes equipment unit, and the structure of original building is not damaged in the high-altitude, and simple in structure, economical and practical.
Description of drawings
Fig. 1 is the heavy mast structure scheme drawing of herringbone of the present utility model.
Fig. 2,3 is running condition figure of the present utility model.
Fig. 4,5 is a running condition figure enlarged drawing of the present utility model, and Fig. 4 is a herringbone lifting mast amplitude peak, and Fig. 5 is a herringbone lifting mast minimum radius.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed description of operation.
The specific embodiment
The herringbone lifting mast is made up of two tubes 1 and a horizon bar 2 among the figure, the head captive joint of two tubes, be fixedly connected with head otic placode 3 at head, end at two tubes is fixedly connected with afterbody otic placode 4, two tubes is connected and composed by some pipe joint spare 5 usefulness bolts 6, the afterbody otic placode of two tubes end is captiveed joint with pivot pin with the beam of embracing in antenna box girder with variable cross section 7 places, gin wheel 8 is installed on the head otic placode, another pulley 9 is installed at the pipe rear portion, be wound with hoist rope 10 on gin wheel and another pulley, the hoist rope top is connected with shackle 11, the hoist rope rear portion is by being located at following winch 12(3t) connect, on the antenna case beam on herringbone lifting mast top, be connected with a fixed pulley 13, antenna box girder with variable cross section place at herringbone lifting mast afterbody otic placode place is provided with a coupling link 14, on coupling link, be fixedly connected with one and pull cucurbit 15, the other end of chain block is walked around fixed pulley by steel wire and is captiveed joint with the head of herringbone lifting mast, it is characterized in that: the two tubes of herringbone lifting mast is a φ 219x6070 millimeter, between 2 otic placodes of herringbone lifting mast afterbody at a distance of 1800 millimeters.
The utility model is that integral body is to be assemblied to form by the less relatively primary structural component of some quality, plants the root place and does not have welding, does not destroy original body; Can realize the luffing function.
For for security consideration, be provided with a 5t chain block as insurance more.One work in, another is followed.So just can avoid because the safety misadventure that the problem of cucurbit causes.
During use, need the segmentation of herringbone lifting mast to be removed at 550 meters platform places with manpower, assemble in the high-altitude, because have only manpower to rely on, so single weight must be less than 50kg, assembling is also captiveed joint with embracing beam and pivot pin with antenna box girder with variable cross section place, and the installation chain block can use.Utilize earlier on the building 3t fixedly loop wheel machine will descend and use pumping source, equipment handling to 454 meter platforms such as hydraulic ram, using the hoist rope of herringbone lifting mast then instead fixes with shackle, and according to the weight and the size of institute's handling appliance, the width of cloth that changes the herringbone lifting mast with chain block is read, in order to avoid the equipment Collision Antenna case beam that hangs, promote with the 3t winch on 454 meters platforms then, to descend and use pumping source, equipment such as hydraulic ram are handling to 529 meter platform place one by one, can carry out the decline of antenna after the installation and install.After treating that at last engineering finishes, remove the herringbone lifting mast.
Need to be about the scaffold tubes of 300mm after installing, the vertical herringbone lifting mast of direction line of centers at herringbone lifting mast end segment midpoint weld length.Can guarantee that like this herringbone lifting mast is unlikely to topple to antenna case beam direction after arriving an elevation angle.So the shackle that relates to all must be stamped insurance with galvanized wire, thereby guarantee that in use the shackle screw rod can not come off.During the work of lifting herringbone lifting mast, winch and chain block cannot be worked simultaneously.One work in, another cannot be operated.In order to avoid cause danger.
