Description

Base bolt quick-tightening device
Technical Field
The utility model relates to a tool equipment, concretely relates to base bolt is tight device soon.
Background
Electric power and oil field workers working in the field have many large-scale bolt fastening projects, such as fixing of a base of a wind generating set and the like. At present, the fastening of the bolts is realized by adopting a traditional bolt fastening mode, and the production mode has the defects of long time consumption, high labor intensity of workers, low operation efficiency and high production cost. And the large automatic tool is inconvenient to carry during field work, the tools are not suitable for being carried by workers, the types of the tools are not too many, and the universal tool is preferred. The length of a base bolt of the wind generating set is too long, a common quick socket wrench in assembly production is not provided in the depth and the size of a socket, and a common tool is difficult to realize quick operation.
Disclosure of Invention
The utility model aims at providing a quick tight device of base bolt to the defect that prior art exists exactly.
The technical scheme is as follows: the base bolt quick-tightening device comprises a power machine, a driving gear, a driven gear, a synchronous belt pulley and a limiting shaft, wherein the driving gear is arranged on a power shaft of the power machine, the end parts of the power machine on the upper side and the lower side of the driving gear are fixedly connected with an upper end cover and a lower end cover through bolts, the synchronous belt pulley is vertically arranged in the upper end cover and the lower end cover and close to the driving gear, the two ends of the synchronous belt pulley are connected with the inner parts of the upper end cover and the lower end cover and can rotate, the driven gear is arranged at one end part of the synchronous belt pulley, and; the left side portion is equipped with two spacing axles in the lower extreme cover, the hold-in range penetrates and is in the suit after between two spacing axles on the synchronous pulley by the uncovered of upper end cover and lower extreme cover front end.
The driving gear and the driven gear are both conical gears.
The power machine is an electric hand drill structure with a storage battery and an electronic speed regulating mechanism.
And two ends of the synchronous belt wheel are connected with the inner walls of the upper end cover and the lower end cover through bearings or shaft sleeves.
The synchronous belt is an annular synchronous belt.
Compared with the prior art, the utility model, have following advantage: the device has the advantages of reasonable design, simple structure, reliable work, simple and convenient operation, convenient maintenance, no need of special training or training and capability of being used by hands; the device obviously reduces the labor intensity of workers, saves physical power, saves a large amount of physical power for field work, and improves other working efficiency.

fig. 2 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
Referring to fig. 1-2, a base bolt quick fastening device comprises a power machine 1, a driving gear 2, a driven gear 3, a synchronous belt 4, a synchronous belt pulley 5 and a limiting shaft 6, wherein the driving gear 2 and the driven gear 3 are both conical gears. The synchronous belt 5 is an annular synchronous belt. A driving gear 2 is arranged on a power shaft of the power machine 1, the end parts of the power machine 1 on the upper side and the lower side of the driving gear 2 are fixedly connected with an upper end cover 7 and a lower end cover 8 through bolts, a synchronous pulley 5 is vertically arranged in the upper end cover 7 and the lower end cover 8 near the driving gear 2, two ends of the synchronous pulley 5 are connected with the upper end cover 7 and the lower end cover 8 in an internal mode and can rotate, a driven gear 3 is arranged at one end part after the synchronous belt 4 is overlapped, and the driven gear 3 and the synchronous pulley 5 are fixed into a whole and are meshed with the driving; the left side portion is equipped with two spacing axles 6 in the lower end cover 8, hold-in range 4 is penetrated and is overlapped on synchronous pulley 5 behind two spacing axles 6 by the uncovered of upper end cover 7 and 8 front ends of lower end cover. The power machine 1 is an electric hand drill structure with a storage battery and an electronic speed regulating mechanism. And two ends of the synchronous belt wheel 5 are connected with the inner walls of the upper end cover 7 and the lower end cover 8 through bearings or shaft sleeves. The two outer sides of the upper end cover 7 and the lower end cover 8 are fixedly connected through screws 9.
When the power machine works, the power machine 1 drives the driving gear 2 to rotate, the driving gear 2 is meshed with the driven gear 3, the driven gear 3 rotates and drives the synchronous pulley 5 to rotate, the synchronous belt 4 is in contact with the synchronous pulley 5, the synchronous belt 4 can rotate along with the synchronous pulley 5, the outer end of the synchronous belt 4 is sleeved on a bolt to be tightened, a handle of the power machine 1 is held by a hand to tighten the synchronous belt 4, the power machine 1 is started and slowly accelerated, and the bolt is driven to rotate by the friction force of the synchronous belt 4 (with a groove therein), so that the purpose of tightening is achieved; due to the continuous driving of the motor, the quick fastening of the base bolt can be realized. The bolt can be loosened by switching the steering of the power machine 1. Since the timing belt pulley 5 is easily worn out, it needs to be replaced regularly.
The utility model has reasonable design, simple structure, reliable work, simple operation and convenient maintenance, does not need special training or training and can be used by the hands; the device obviously reduces the labor intensity of workers, saves physical power, saves a large amount of physical power for field work, and improves other working efficiency.
