Abstract
The utility model relates to a novel inserted chain jib device, including the lead screw, the lead screw lower part is provided with the chain and connects, and the chain connects the sub -unit connection has the chain, the lead screw lower part adopts threaded connection to connect upper portion at the chain, the chain connects upper portion and is provided with the fixed plate, and the lead screw passes the fixed plate setting, and fixed plate upper portion is provided with the nut. Among the the device, the chain connects one end tapping processing, and the tapping degree of depth probably is 10-15mm, twists the chain with lead screw one end and connects rather than the perfect fitting, then carry out welding treatment. Welding back deburring, the sharp edge. Passing the fixed plate with the lead screw of chain jib, using tighten nut, the chain jib is with regard to the installation like this. The utility model discloses a device adopts to weld behind the threaded connection and forms, has both saved the expense of detecting a flaw, even weld insecurely, still has threaded connection to can prevent that two parts break away from, simultaneously, the complexity of processing has been solved to this structure.
Description
Technical field
The utility model belongs to chain suspension rod technical field, is specifically related to a kind of novel mosaic chain derrick rig.
Background technique
At present, simple lifting chain suspension rod has two kinds of production methods on the market, and one is directly welded with chain joint by screw mandrel, so general needs are detected a flaw, otherwise there will be welding part phenomenon of rupture, another is then that entirety machined into forms, and takes very much material, takes a lot of work.
Model utility content
The utility model relates to a kind of inserted chain derrick rig, and chain suspension rod is made up of two-part, and screw mandrel and a chain joint combine, the tapping of chain joint one end, screw mandrel is screwed into chain joint, then two weld parts is integrated, enhances its firmness.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of novel mosaic chain derrick rig, comprise screw mandrel, screw mandrel bottom is provided with chain joint, and chain joint bottom is connected with chain; Screw mandrel bottom adopts and is threaded in chain joint top; Chain joint top is provided with fixed plate, and screw mandrel is arranged through fixed plate, and fixed plate top is provided with nut.
Further, the degree of depth that chain joint top is connected with screw mandrel lower thread is 10 ~ 15mm.
In this device, the tapping of chain joint one end is processed, and tapping depth is probably 10 ~ 15mm, screw mandrel one end is screwed into chain joint and coordinates completely with it, then carries out soldering.Burr is removed, sharp edge after welding.By the screw mandrel of chain suspension rod through fixed plate, with nut screwing clamping, such chain suspension rod is with regard to installation.In this structure, the multichain bar suspension rod no matter in chain applies the power in any direction, all can not destroy the structure of chain suspension rod.
The beneficial effect of this model utility is: this model utility device is welded after adopting and being threaded, and has both eliminated flaw detection expense, even if not prison welding is solid, also have and be threaded, thus can prevent two parts from departing from, meanwhile, this structure solves the complexity of processing.
Accompanying drawing explanation
Fig. 1 is institute's operative installations structural representation in the utility model embodiment.
Description of symbols in figure: 1, screw mandrel; 2, chain joint; 3, nut; 4, fixed plate; 5, chain.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, better to understand the utility model.
Novel mosaic chain derrick rig as shown in Figure 1, comprises screw mandrel 1, and screw mandrel 1 bottom is provided with chain joint 2, and chain joint 2 bottom is connected with chain 5; Screw mandrel 1 bottom adopts and is threaded in chain joint 2 top; Chain joint 2 top is provided with fixed plate 4, and screw mandrel 1 is arranged through fixed plate 4, and fixed plate 4 top is provided with nut 3.
In this device, the tapping of chain joint 2 one end is processed, and tapping depth is probably 10 ~ 15mm, screw mandrel 1 one end is screwed into chain joint 2 and coordinates completely with it, then carry out soldering.Burr is removed, sharp edge after welding.By the screw mandrel 1 of chain suspension rod through fixed plate 4, tighten with nut 3, such chain suspension rod is with regard to installation.In this structure, the multichain bar suspension rod no matter in chain 5 applies the power in any direction, all can not destroy the structure of chain suspension rod.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
