Abstract
The utility model relates to an installing tool for a roller chain, in particular to a roller chain installing device, which is frequently used during maintenance and installation. The roller chain installing device comprises a left grabbling hook seat and a right grabbling hook seat provided with grabbling hooks at the bottom. The left grabbling hook seat is fixedly provided with a bolt, the right grabbling hook seat is provided with a through hole in clearance fit to the bolt, and the bolt is arranged in the through hole. The right grabbling hook seat is fixedly provided with a guide rod, the left grabbling hook seat is provided with a guide rod hole in clearance fit to the guide rod, and the guide rod is arranged in the guide rod hole. The guide rod is arranged in parallel to the bolt, and one end of the bolt is provided with a nut for adjusting the distance between the grabbling hooks. When the roller chain forms a closed loop so that an installation joint can not be clamped, the roller chain installing device can clamp both ends of the roller chain by means of force, which is convenient to joint installation. Meanwhile, the roller chain installing device is also applicable to other linear clamping occasions.
Description
Technical field
The utility model relate to a kind of in maintenance, in installing the common employed erecting tools of roller chain, especially a kind of roller chain mounting-connecting device(material).
Background technology
The roller chain transmission has been a kind of very common drive mechanism in the middle of industrial production, and for making roller chain transferring power normally, its tensioning mode can be divided into direct tensioning and tensioning indirectly.So-called directly tensioning is adjusted main passive center distance by mobile drive source (motor, reductor etc.) exactly, thereby reaches the tensioning purpose.So-called tensioning indirectly is exactly by middle device the roller chain application of force to be reached tensioning purpose to roller chain.But which kind of mode no matter, regular meeting runs into that roller chain forms closed loop and differs fraction with pitch and can't erection joint when the maintenance and installation roller chain, will unclamp the passive centre distance of drive source adjustment master for direct tensioning mode like this, then tightens up fastening; Will dismantle middle device for indirect tensioning mode, then assembling.Still therefore the erecting tools that does not have at present specialty needs many people compounding practice, and some dangerous operating mode is operated difficulty more.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of roller chain mounting-connecting device(material), and when roller chain formation closed loop can't be tightened up erection joint, this roller chain mounting-connecting device(material) power of just can borrowing be tightened up roller chain two ends, makes things convenient for erection joint.Simultaneously also tighten up occasion applicable to other linearities.
The utility model solves the problems of the technologies described above by following technical proposals: a kind of roller chain mounting-connecting device(material), comprise that the bottom is fixed with the left claw hook seat and the right claw hook seat of claw hook, be fixed with a bolt on the described left claw hook seat, offer through hole on the described right claw hook seat with described bolt matched in clearance, described bolt is arranged in the described through hole, be fixed with a guide rod on the described right claw hook seat, described left claw hook seat is provided with the guide rod hole with described guide rod matched in clearance, described guide rod is arranged in the described guide rod hole, described guide rod and described bolt be arranged in parallel, and described bolt one end is provided with the nut that is used to regulate distance between claw hook.
As preferably, be formed with optical axis section that cooperates with through hole and the thread segment that cooperates with nut on the described bolt.
As preferably, described nut is a flange nut.
Guide rod on the described right grapple seat is to be used for guaranteeing the rectilinear motion of grapple under the effect of spiral power; One section of cooperating of bolt on the described left grapple seat and through hole is an optical axis section and parallel with guide rod, in order to guarantee two grapples rectilinear motion at grade; Further, the size of grapple needs to be complementary with roller chain roller and pitch, guarantees to hook the roller of roller chain.
The beneficial effect that the utility model brings is, this roller chain mounting-connecting device(material) hooks folding and unfolding by grapple with chain by means of guide rod and bolt, utilizes flange nut to make in the spiral power on the bolt and does linear movement on the direction of two grapples at guide rod and tighten up roller chain two ends with this.

The specific embodiment
1-4 describes in further detail the utility model below in conjunction with accompanying drawing:
Shown in Fig. 1-4, a kind of roller chain mounting-connecting device(material), comprise that the bottom is fixed with the left claw hook seat 1 and the right claw hook seat 6 of claw hook 3, be fixed with a bolt 4 on the described left claw hook seat 1, offer through hole 7 on the described right claw hook seat 6 with described bolt 4 matched in clearance, described bolt 4 is arranged in the described through hole 7, is formed with optical axis section that cooperates with through hole 7 and the thread segment that cooperates with nut 8 on the described bolt 4.Be fixed with a guide rod 5 on the described right claw hook seat 6, described left claw hook seat 1 is provided with the guide rod hole 2 with described guide rod 5 matched in clearance, described guide rod 5 is arranged in the described guide rod hole 2, and described bolt 4 one ends are provided with the nut 8 that is used to regulate distance between claw hook, and described nut 8 is a flange nut.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
