Abstract
The utility model relates to a device which is applied to control a connector assembling gap in processing of a metal container or a pipeline and the like, in particular to a spiral tensioner used for assembling weld of the metal container or the pipeline. The spiral tensioner used for assembling weld of the metal container or the pipeline comprises a threaded rod, a nut, and rockers, wherein two ends of the threaded rod is respectively provided with left-hand threads and right-hand threads, the left-hand threads are provided with a left-hand nut, and the right-hand threads are provided with a right-hand nut. The middle portion of the threaded rod is provided with a left through hole and a right through hole, and the rockers are assembled on the left through hole and the right through hole. Compared with the prior art, the spiral tensioner is small in size, convenient to use, firm and reliable in fixation, precise to a millimeter range in adjustment amount, large in adjustable range, suitable for various welded joints such as butt joint, angle joint, and lap joint, capable of being reused, capable of conveniently exchanging easily damaged part square nuts, and capable of achieving aims of economy, convenience, and high efficiency.
Description
Technical field
The utility model relates to a kind of control joint group that is applied in the processing and fabricatings such as canister or pipeline to the device, particularly a kind of spiral tensioning device for canister or tube group butt welding in gap.
Background technology
The operation that " welding " arranged in the making such as canister, the pipeline process, the group that group will strictly be controlled welding point to process are to the gap, and the gap too greatly then is difficult to welding, and the gap is too small can't to guarantee welding quality again.Traditional group adopts the mode have the devices such as crane cooperations, chain block cooperation to match to device, but the aforesaid way existence is such as shortcoming as described in the following table:
| Mode | Shortcoming |
| Crane cooperates (large part) | Expense is high, and adjustment amount is large, is difficult to control group to the gap |
| Chain block cooperates | Suspension centre need be set, and adjustment amount is large, is difficult to control group to the gap |
| Crowbar cooperates the buting iron sled | Effort, dangerous, adjustment amount is little, can only turn down and can not tune up the gap group, easily causes misalignment |
| The bolt tension | Effort, adjustment amount is little, only the welding of the small containers equipment such as applicable banjo fixing butt jointing and pipeline |
Summary of the invention
The purpose of this utility model is safety, solve fine setting group in canister or the pipe string process easily provides a kind of spiral tensioning device for canister or tube group butt welding to the problem in gap.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of spiral tensioning device for canister or tube group butt welding, comprise screw rod, nut, rocking bar, the two ends of described screw rod are respectively equipped with left hand thread and right-handed thread, and this left hand thread end is equipped with left-handed nut, and described right-handed thread end is equipped with the right-handed nut, the middle part of described screw rod is provided with left and right two through holes, and this left and right through hole is equipped with rocking bar.
The utility model compared with prior art, volume is little, easy to use, fixed safety, adjustment amount can be accurate to a millimeter scope, and adjusting range is large, be applicable to the multiple welding points such as docking, corner connection, overlap joint, and can be repeatedly used, it is convenient to change for the consumable accessory square nut, can reach in actual applications economic, convenient, efficient purpose.
Preferred version of the present utility model is:
Described left-handed nut and right-handed nut are respectively square nuts.
Both axis of described left through hole, right through hole are 90 ° of angles.
Description of drawings
Fig. 1 is the structural representation of tension device.
Fig. 2 is the structural representation of square nut.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
A kind of spiral tensioning device for canister or tube group butt welding is referring to accompanying drawing 1 and accompanying drawing 2, among the figure: screw rod 1, left-handed nut 2, left through hole 3, right through hole 4, right-handed nut 5, rocking bar 6.
The two ends of screw rod 1 are respectively equipped with left hand thread and right-handed thread, and the left hand thread end is equipped with left-handed nut 2, and the right-handed thread end is equipped with right-handed nut 5, and the middle part of screw rod 1 is provided with left and right two through holes, and both axis of left through hole 3 and right through hole 4 are 90 ° of angles; Left and right through hole 3,4 is equipped with rocking bar 6.Left-handed nut 2 and right-handed nut 5 are respectively square nuts.
In the present embodiment, left-handed nut 2 is connected with the right-handed nut and is crossed spot welding with canister, device for cleaning pipeline and be connected, rocking bar 6 alternately inserts in screw rod 1 middle left through hole 3 and the right through hole 4, and by rotation rocking bar 6, make screw rod 1 with respect to left-handed nut 2 and right-handed nut 5 motion of spinning, thereby control two foldings of waiting to organize to equipment.
Left-handed nut 2 and right-handed nut 5 are sub-packed on the screw rod 1, according to the required group of equipment spacing between left-handed nut 2 and the right-handed nut 5 are adjusted in the gap.In the time of group will being tuned up the gap, left-handed nut 2 and right-handed nut 5 should be close; In the time of need dwindling group to the gap, then left-handed nut 2 and right-handed nut 5 are by far away.Left-handed nut 2 after mixing up and right-handed nut 5 are welded in respectively on the right two parts equipment of need group, rotate rocking bar 6 by hand, turn clockwise and to dwindle group to the gap, be rotated counterclockwise the amplification group the gap, wait to organize the suitable laggard spot welding in gap is fixed, cut off the solder joint of left-handed nut 2 and right-handed nut 5 and equipment room, pull down tension device, equipment interface is welded.
Points for attention during use: when using tension device that equipment, pipeline etc. is grouping adjust the play, should avoid powerful group; Left-handed nut 2 and right-handed nut 5 should polish smooth the solder joint of leaving on the equipment after removing from equipment; The tension device threaded portion is answered the intermittent oiling maintenance.
