A kind of pipe prefabrication lowering or hoisting gear
Technical field
The utility model relates to a kind of pipe prefabrication lowering or hoisting gear, when being mainly used in pipe prefabrication to the support of pipeline.
Background technology
When pipeline formed a team to weld, an end need be installed on the welding deflection machine, and the other end then needs to rely on foreign object to keep the levelness of pipeline integral body, and normally used is the pipeline rack.During the pipeline butt welding, place if can't guarantee pipe level, will cause various weld defects, influenced the qualification rate of product.Existing pipeline rack all is to make specially according to the specification of pipeline usually, do not possess the function of adjusting, thereby the scope of application is little, has caused manpower waste physically.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is easy to use, adjustable for height pipe prefabrication lowering or hoisting gear.
The technical scheme in the invention for solving the above technical problem is: this pipe prefabrication is with the design feature of lowering or hoisting gear: comprise pipeline support portion, screw mandrel, nut, support and screw mandrel sleeve pipe, described nut is arranged on the screw mandrel, this nut and screw mandrel match, described screw mandrel top is provided with for the pipeline support portion of supporting pipeline, this pipeline support portion is the V-type that opening makes progress, this screw mandrel passes support and is arranged on the support by nut, described screw mandrel sleeve pipe is fixed on the support and with screw mandrel and matches, and this screw mandrel sleeve pipe is positioned at the below of nut.The utility model is simple in structure, reasonable in design; The screw mandrel sleeve pipe be arranged so that the screw mandrel lifting time stablize firmly more, and screw mandrel formed protection; Only with hand is fixed the pipeline support portion during use, and it can not be rotated, and rotating nut can drive the lifting of screw mandrel again, thereby realizes the lifting of pipeline.
The utility model also comprises handle, and described handle is fixed on the nut.Be used for rotating nut, make that use is convenient.
The utility model also comprises rubber blanket, and described rubber blanket is arranged on the pipeline support portion.During duty, the friction between pipeline and pipeline support portion increases, and makes that pipeline is difficult for rolling or sliding, and also can prevent from causing pipe surface to scratch.
The utility model also comprises wheel, and described wheel is arranged on the bottom of support.Make that movement, the carrying of this lowering or hoisting gear are convenient laborsaving.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, by being used of screw mandrel and nut, can regulate duct height, make operating efficiency higher, the use of rubber blanket can effectively prevent the damage of pipe surface, the position of this lowering or hoisting gear can be moved or adjust to the setting of wheel more easily, and the screw mandrel sleeve pipe makes to be difficult in the lifting process producing and rocks and influence work, further improves stability.

Fig. 1 is the structural representation that pipe prefabrication is used lowering or hoisting gear in the utility model.
The pipe prefabrication use state diagram of lowering or hoisting gear in Fig. 2 the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1~Fig. 2, the pipe prefabrication in the present embodiment comprises pipeline support portion 1, screw mandrel 2, nut 3, support 4, handle 5, rubber blanket 6, wheel 7 and screw mandrel sleeve pipe 8 with lowering or hoisting gear, wherein the V-type that makes progress for opening of pipeline support portion 1.Support 4 is hollow structure, and the top of support 4 is gripper shoe 10, is used for holding nut 3, and nut 3 is played position-limiting action.
Nut 3 in the present embodiment is arranged on the screw mandrel 2; this nut 3 matches with screw mandrel 2; screw mandrel 2 tops are provided with for the pipeline support portion 1 of supporting pipeline 9; " V " type that this pipeline support portion 1 makes progress for opening; this screw mandrel 2 passes support 4 and is arranged on the support 4 by nut 3; only with hand is fixed pipeline support portion 1 during use; it can not be rotated; rotating nut 3 can drive the lifting of screw mandrel 2 again; thereby realize the lifting of pipeline 9, screw mandrel sleeve pipe 8 is fixed on gripper shoe 10 bottoms of support 4 and matches with screw mandrel 2, and this screw mandrel sleeve pipe 8 is positioned at the below of nut 3; screw mandrel sleeve pipe 8 be arranged so that screw mandrel 2 liftings the time stablize firmly more, and screw mandrel 2 formed protection.
Handle 5 in the present embodiment is fixed on the nut 3, is used for rotating nut 3, makes that use is convenient.
Rubber blanket 6 in the present embodiment is arranged on the V-shaped pipeline support portion 1, and during duty, the friction that pipeline 9 and pipeline support portion are 1 increases, and makes that pipeline 9 is difficult for rolling or sliding, and also can prevent pipeline 9 surface tears.
Wheel 7 in the present embodiment is arranged on the bottom of support 4, make this lowering or hoisting gear movement, the carrying convenient laborsaving.
Pipe prefabrication in the present embodiment is used for supporting and lifting pipeline 9 with lowering or hoisting gear, only need fix pipeline support portion 1 during use, and it can not be rotated, and can drive the lifting of screw mandrel 2 again by handle 5 rotating nuts 3, thereby realizes the lifting of pipeline 9.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different, the above content described in this specification only is to the explanation of the utility model structure example.Allly conceive equivalence variation or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
